        * Version 27.2 released.

2021-03-18 Basil L. Contovounesios <contovob@tcd.ie>

        Fix 'frame-inner-height' in non-GUI builds

        Include tab bar in frame's inner height in non-GUI builds that
        don't define 'tab-bar-height'.  This is consistent with the
        inclusion of the menu bar in the calculated height.  It is also
        consistent with TTY frames of GUI builds, for which
        'tab-bar-height' is always zero anyway (bug#47234).
        Fix suggested by Eli Zaretskii <eliz@gnu.org>.

        * lisp/frame.el (frame-inner-height): Don't assume
        'tab-bar-height' is defined in builds --without-x.

2021-03-18  Stefan Monnier  <monnier@iro.umontreal.ca>

        Revert "* lisp/mouse.el: Fix mouse-1-clock-follows-mouse = double"

        This reverts commit 02a5cfce471613f671722b35536d2a78f17b0429.
        That commit breaks because of a missing patch to `parse_modifiers_uncached`
        in `src/keyboard.c`.  IOW, too risky for `emacs-27`.

        Don't merge to `master`.

2021-03-18  Stefan Monnier  <monnier@iro.umontreal.ca>

        * lisp/mouse.el: Fix mouse-1-clock-follows-mouse = double

        This functionality was broken by commit 3d5e31eceb9dc1fb62b2b2,
        the problem being that we end up considering as distinct the events
        `down-double-mouse-1` and `double-down-mouse-1`.

        Reported by Eyal Soha <eyalsoha@gmail.com>

        (mouse--click-1-maybe-follows-link): Make sure the last element of
        the list passed to `event-convert-list` is indeed a "basic" event.

2021-03-18  Stefan Monnier  <monnier@iro.umontreal.ca>

        * lisp/emacs-lisp/gv.el (edebug-after): Don't run the getter in the setter

        This fixes bug#46573 which was introduced by commit
        d79cf638f278e50c22feb53d6ba556f5ce9d7853.
        The new code is a middle ground, which makes sure the instrumentation
        point is used (so the coverage checker won't have ghost unreachable
        instrumentation points) yet without artificially running the getter
        when we only need to run the setter.

2021-03-18  Masahiro Nakamura  <tsuucat@icloud.com>

        * doc/misc/tramp.texi (Remote shell setup): Fix reference. (Do not merge)

2021-03-18  Eli Zaretskii  <eliz@gnu.org>

        'while-no-input-ignore-events' after loading the dump file.
        (Bug#46940)

2021-03-18  Eli Zaretskii  <eliz@gnu.org>

2021-03-18  Eli Zaretskii  <eliz@gnu.org>

        Avoid crashes in Mew due to corrupted tool-bar label

        * src/gtkutil.c (update_frame_tool_bar): Don't keep around a
        'char *' pointer to a Lisp string's contents when calling Lisp,
        because that could relocate string data; keep the Lisp string
        itself instead.  This avoids crashes in Mew.  (Bug#46791)

        * lisp/comint.el (comint-password-prompt-regexp): Match all

        * lisp/image-mode.el (image-toggle-display-image): Preserve point

2021-03-18  Eli Zaretskii  <eliz@gnu.org>

        Fix language-environment and font selection on MS-Windows

        These changes improve setting the language-environment and font
        selection when MS-Windows returns useless "ZZZ" as the "language
        name", which then disrupts all the setup of the locale-dependent
        stuff, and in particular font selection.
        * lisp/w32-fns.el (w32-charset-info-alist): Add an element for
        "iso8859-5", in case LANG is set to something unusable, like
        "ZZZ".  This allows fonts capable of displaying Cyrillic
        characters to be used even when language preferences are screwed.

        * src/w32.c (init_environment): If GetLocaleInfo returns "ZZZ" as
        the "language name" for LOCALE_USER_DEFAULT, try again with locale
        ID based on what GetUserDefaultUILanguage returns.  (Bug#39286)

        the former.
        (command-line): Call 'startup--load-user-init-file' with last arg
        t: there's no longer any need to test the value of
        'inhibit-default-init' here, as it will be tested by the called

        Fix problem with 8bit content-transfer-encoding in nndoc mbox files

        * lisp/gnus/nndoc.el (nndoc-possibly-change-buffer): If we're
        reading an mbox file, it may contain messages that use
        content-transfer-encoding 8bit, which means that we have to treat
        the file as a sequence of byte (bug#42951).  This avoids
        double-decoding -- once by Emacs when inserting the mbox into the
        buffer, and once by Gnus when displaying the articles.

        Revert "Fix incorrect handling of module runtime and environment pointers."

        This reverts commit cdc632fbe6e149318147a98cccf1b7af191f2ce8.
        Those changes are too significant and non-trivial to be
        suitable for a release branch at this time.

2021-02-03  Philipp Stephani  <phst@google.com>

        Fix incorrect handling of module runtime and environment pointers.

        We used to store module runtime and environment pointers in the static
        lists Vmodule_runtimes and Vmodule_environments.  However, this is
        incorrect because these objects have to be kept per-thread.  With this
        naive approach, interleaving module function calls in separate threads
        leads to environments being removed in the wrong order, which in turn
        can cause local module values to be incorrectly garbage-collected.

        Instead, turn Vmodule_runtimes and Vmodule_environments into
        hashtables keyed by the thread objects.  The fix is relatively
        localized and should therefore be safe enough for the release branch.

        Module assertions now have to walk the pointer list for the current
        thread, which is more correct since they now only find environments
        for the current thread.

        Also add a unit test that exemplifies the problem.  It interleaves two
        module calls in two threads so that the first call ends while the
        second one is still active.  Without this change, this test triggers
        an assertion failure.

        Fix cond jump table compilation (bug#42919)

        This bug affected compilation of

         (cond ((member '(some list) variable) ...) ...)

        While equal is symmetric, member is not; in the latter case the
        arguments must be a variable and a constant list, in that order.

        Reported by Ikumi Keita.

        * lisp/emacs-lisp/bytecomp.el (byte-compile--cond-switch-prefix):
        Don't treat equality and member predicates in the same way; only

        Backport: Fix subtle bug when checking liveness of module values.

        We can't simply look up the Lisp object in the global reference table

        Backport: Fix memory leak for global module objects (Bug#42482).

        Instead of storing the global values in a global 'emacs_value_storage'

        clicking on a widget in the customize buffer applies changes in the

        If automatic character composition triggers GC, and

        Consider face inheritance when checking region face background.

        Some themes (like dracula) make the region face inherit from some
        other face.  If the background color of the region was inherited,
        `indicate-copied-region' did the switch-point-and-mark-twice dance
        which is not visible in case the region is highlighted.  It just
        looked like Emacs would hang for a second after M-w.

        * lisp/simple.el (indicate-copied-region): Consider face inheritance
        when checking region face background.

        in options.

        * doc/lispref/keymaps.texi (Extended Menu Items): Tweak :key-sequence

        Don't make it sound like `:key-sequence nil` is any different than the
        absence of `:key-sequence`.  And the performance advantage of
        `:key-sequence` disappeared long ago.

        Fix redisplay when scrolling under redisplay-dont-pause

        * src/dispnew.c (update_window): Reset the window's
        'must_be_updated_p' flag if the window's update was completed
        without interruption.  This fixes redisplay glitches when
        'redisplay-dont-pause' is nil, at least on MS-Windows, because
        'expose_window' doesn't redraw the exposed rectangle when the
        window's 'must_be_updated_p' flag is set.

        'resize-mode' resize policy as well.

2020-04-06  Martin Rudalics  <rudalics@gmx.at>

        Fix some problems with moving and resizing child frames

        (1) Provide new option 'x-gtk-resize-child-frames' which allows
        to either hide a child frame during resizing or asks GTK to
        resize it "immediately".  This is needed because desktops like
        GNOME shell otherwise won't allow resizing child frames at all.
        (2) Do not try to synchronize the position of a child frame
        after moving it.  Needed because the present implementation
        introduces a 0.5 secs delay which makes dragging child frames
        virtually impossible with Lucid and Motif toolkits on desktops
        like GNOME shell that use invisible outer frame borders.

        For further information see the thread starting with
        https://lists.gnu.org/r/emacs-devel/2020-01/msg00343.html

        * src/xterm.c (x_set_offset): Don't x_sync_with_move for child

        Don't signal during backtrace unrewind (Bug#40088)

        backtrace_eval_unrewind is used to temporarily reverse
        let-bindings (it's called with a positive argument to reverse
        bindings, and then a negative argument to re-apply them) by
        backtrace--locals and backtrace-eval.  For the SPECPDL_LET_DEFAULT and
        SPECPDL_LET_LOCAL cases (which occur for let-bindings on buffer-local
        variables), the code calls Fdefault_value and Fbuffer_local_value on
        the symbol.

        For symbols which are unbound at top-level, the first (with positive
        argument) call to backtrace_eval_unrewind will set the symbol's value
        to unbound (putting the current value in the specpdl's "old value"
        slot).  On the second (with negative argument) call,
        backtrace_eval_unrewind attempts to retrieve the symbol's value with
        Fdefault_value or Fbuffer_local_value, but that raises a void-variable
        signal.  This interrupts the restoration of the let-bindings, so any
        other variables more recent on the stack will now have the wrong
        value.

        * src/data.c (default_value): Make non-static.
        * src/lisp.h: Declare it.
        * src/eval.c (backtrace_eval_unrewind): Replace the calls to
        Fdefault_value and Fbuffer_local_value with default_value and
        buffer_local_value, respectively.  The latter do exactly the same as
        the former, except if the symbol's value is Qunbound they just return
        it instead of signaling void-variable.

        Fix a couple of problems in changelog generating functions

        easily happen since we are calling end-of-defun on a partial code
        fragment from a diff.
        * lisp/vc/log-edit.el (log-edit-generate-changelog-from-diff): Bind

        Most of the manual here addresses Message mode, yet talks about
        'send-mail-function' which is used for Mail mode.
        Fixing this completely requires more involved work, but for now at
        least document the difference here.

        Skip shell prompt on current line in Eshell even if it's protected

        When the eshell prompt is protected (e.g., with rear non-sticky,
        inhibited movements, etc.), 'beginning-of-line' won't move to the
        actual beginning of the line and therefore won't skip over the

        Make OMake support slightly less expensive (bug#39595)

        When run with -p or -P, OMake regurgitates error messages that
        prevented further progress, indented by 6 spaces.  Use that fact
        to ameliorate the modification done to other error message regexps.

        * lisp/progmodes/compile.el (compilation-parse-errors):
        When 'omake' is enabled, allow error messages to be indented by 0 or 6
        spaces instead of any number of spaces, to avoid pathological
        behaviour.
        (compilation-error-regexp-alist-alist): Anchor the 'omake' pattern to
        bol for performance.  Repair the 'ruby-Test::Unit' pattern, which

        Speed up 'msft' and 'watcom' compilation error regexps

        They have similar structure, and both suffer from being able to
        match leading spaces in multiple ways which leads to bad performance
        when backtracking (bug#39595).

        * lisp/progmodes/compile.el (compilation-error-regexp-alist-alist):
        Improved 'msft' and 'watcom' regexps.

        Speed up 'maven' compilation error message regexp

        Anchor the regexp at line-start to prevent quadratic behaviour when
        it doesn't match (bug#39595).  It's unclear whether the type tag, like
        [ERROR], is always present; we keep it optional just in case.

        * lisp/progmodes/compile.el (compilation-error-regexp-alist-alist):
        Rewrite 'maven' regexp, using rx for clarity.
        * etc/compilation.txt (maven): More examples.
        * test/lisp/progmodes/compile-tests.el
        (compile-tests--test-regexps-data): No leading spaces; they seems to
        stem from a misunderstanding in bug#11517.

        This argument was added for the 'or' clause in rx, but it turned out

        rx: Use longest match for all-string 'or' forms (bug#37659)

        Revert to the Emacs 26 semantics that always gave the longest match
        for rx 'or' forms with only string arguments.  This guarantee was
        never well documented, but it is useful and people likely have come to
        rely on it.  For example, prior to this change,

         (rx (or ">" ">="))

        matched ">" even if the text contained ">=".

        Add more blackboard bold characters to TeX input method

        This patch adds all capital blackboard bold letters and those for "1"
        and "2". Most characters are in common use in mathematics, but it does
        not seem useful to exclude the few not widely used.

        Fix the notification action for PRIVMSG in erc-notifications-notify

        * lisp/erc/erc-desktop-notifications.el (erc-notifications-notify):
        explicitly request the buffer for `nick', rather than relying on
        (current-buffer) returning it.  That works fine for the very first
        PRIVMSG sent by `nick', but ERC seems to handle subsequent PRIVMSGs
        differently, where (current-buffer) would return the server buffer
        rather than the existing buffer for PRIVMSGs from `nick'.

        Add unattended spell-checking to checkdoc

        This commit makes checkdoc capable of spell-checking even when the
        user isn't using it interactively.  When TAKE-NOTES is non-nil,
        checkdoc will run spell-checking (with ispell) and report spelling
        mistakes.

        Fixes: (bug#38583).

        * lisp/textmodes/ispell.el (ispell-word): Extract part of it to
        `ispell--run-on-word`.
        (ispell--run-on-word): New function, extracted from `ispell-word`.
        (ispell-error-checking-word): New function.
        (ispell-correct-p): New function.  Use `ispell--run-on-word` and
        `ispell-error-checking-word`.
        * lisp/emacs-lisp/checkdoc.el (checkdoc-current-buffer): Pass
        TAKE-NOTES to `checkdoc-start`.
        (checkdoc-continue): Pass TAKE-NOTES to `checkdoc-this-string-valid`.
        (checkdoc-this-string-valid): Add optional argument TAKE-NOTES and
        pass it to `checkdoc-this-string-valid-engine`.
        (checkdoc-this-string-valid-engine): Add optional argument TAKE-NOTES
        and pass it to `checkdoc-ispell-docstring-engine`.
        (checkdoc-ispell-init): Call `ispell-set-spellchecker-params` and
        `ispell-accept-buffer-local-defs`.  These calls are required to
        properly use ispell.  The problem went unnoticed until now because
        checkdoc was only using ispell through the high-level command
        `ispell-word` which takes care of all the initialization for the user.
        (checkdoc-ispell-docstring-engine): Add optional argument TAKE-NOTES
        to force reporting of spell-checking errors.  Throw error
        when (checkdoc-ispell-init) fails configuring ispell.  Replace a
        few (if cond nil body) with (unless cond body). Replace (let ((var
        nil))) with (let (var)).  Replace (if (not (eq checkdoc-autofix-flag
        'never)) body) with just body because `checkdoc-autofix-flag` is
        checked at the beginning of the function.

        Fix compression of directories in Dired

        This fixes comporession and uncompression of directories on
        MS-Windows, but also on other systems.  The original code used
        ":" as the REGEXP of the directory entry in
        dired-compress-file-suffixes, which on Windows always matched any
        absolute file name, and can also match unusual file names on Posix
        hosts.  This false match would cause dired-compress-file to act as
        if we are decompressing a directory, but use a command suitable
        for compression, which would fail in interesting ways.
        We now use a REGEXP that can never match any valid file name.

        * lisp/dired-aux.el (dired-compress-file-suffixes): Make the
        "compress directory" entry's REGEXP really fail to match any valid
        file name.
        (dired-compress-file): Adapt to the change in
        dired-compress-file-suffixes.  (Bug#39024)
        (dired-compress): If the current file is a directory, or if the
        uncompressed file is a directory, don't remove the original from
        the listing, since it is left in the filesystem.

        Fix redisplay when mode-line-format changes mode-line's height

        * lisp/frame.el (top-level): Add mode-line-format,
        tab-line-format, and header-line-format to the list of variables
        that should trigger an immediate redisplay of the buffer's

        in preference to CURRENT_MODE_LINE_HEIGHT,

        respectively.  This fixes display of vertical scroll bar when the
        height of the window's mode line changes.
        * src/dispnew.c (adjust_glyph_matrix): When resizing a window's
        matrix, reset the mode_line_p flag of the previous mode-line row,
        so that the window_box_height, CURRENT_MODE_LINE_HEIGHT, and their
        ilk won't use stale info.  (Bug#38828)

        Move flex style's minibuffer-default-aware sorting to lisp/icomplete.el

        This moves the logic from the series of commits starting in the commit named:

          Improve sorting of flex completion style with non-nil minibuffer-default

        to lisp/icomplete.el, so far the only confirmed beneficiary of that
        functionality.

        * lisp/icomplete.el (icomplete--sorted-completions): Consider

        Fix tar-mode reading the oldgnu Tar format

        This makes sure an entry for a long file name will not
        accidentally appear as a directory, and thus its size will be
        disregarded, causing corrupted file headers for all the subsequent
        entries.  The original problem happened because the long file name
        truncated to 99 bytes happened to end in a slash, which tar-mode
        takes to be the indication of a directory.
        * lisp/tar-mode.el (tar-header-block-tokenize): Accept an
        additional argument DISABLE-SLASH; if non-nil, don't set the
        link-type field of the descriptor to 5 (meaning a directory) just
        because the name ends in a slash.  Use this argument when calling
        itself recursively, to read the entry of the file with a long
        name.  Set the link-type to 5 if the long name ends in a slash.

        Document and verify that emacs_limb_t doesn’t have padding bits.

        This is a useful property when doing further bit-twiddling with the
        magnitude array before/after calling extract_big_integer or
        make_big_integer.  For example, constructing an emacs_limb_t object
        using repeated shift-and-add should work as expected, but relies on
        the type not having padding bits.  Since the C standard already
        guarantees that unsigned integers use a pure binary representation,
        not having padding bits is enough to guarantee that the type has
        unique object representations in the sense of C++’s
        std::has_unique_object_representations.

        * doc/lispref/internals.texi (Module Values): Document that

        now skips re-sorting the completions completely if there is no

        Improve sorting of flex completion style with non-nil minibuffer-default

        This affects the behaviour of flex completion when there is a default
        completion and the user hasn't entered any input pattern to flex-match
        against.  It is most visible when icomplete-mode or fido-mode are
        being used in conjunctio.

        When using M-x man, for instance, the default completion is picked
        from text around point.  Say it is "emacs" (for Emacs's man page).  It
        will not match the intended completion, "emacs(1)", exactly.  If the
        user hasn't yet given any input to the completion prompt, that
        completion should bubble to top so that
        icomplete-force-complete-and-exit will select it, but it didn't.

        This new approach uses 'string-prefix-p' instead of 'equal' to find
        the default to bubble to the top.  This strategy could eventually be
        improved, most naturally by flex-matching the default string to all
        the candidates and picking the highest scoring one.

        Additionally, the new strategy only considers minibuffer-default if
        there is no input in the minibuffer, which seems sensible and produces
        a small but noticeable speedup.

        * lisp/minibuffer.el (completion--flex-adjust-metadata):
        Reformulate sorting strategy.

        Treat passed strings as raw-text when percent-escaping in epg

        The strings contained in gpg keys can contain UTF-8 data, but can also
        use percent-escapes to encode non-ASCII chars.  When converting those

        * src/emacs-module.c: Add a few more restrictions for emacs-module.h

2019-12-04  Philipp Stephani  <phst@google.com>

        Change module interface to no longer use GMP objects directly.

        As described in the new comment added to emacs-module.c, using GMP
        directly in the module interface has significant downsides: it couples
        the module interface directly to the implementation and requires
        module authors to link their module against the same GMP library as
        Emacs itself, which is often difficult and an unnecessary burden.  By
        picking a representation for the magnitude that often matches the one
        used by GMP, we can avoid overhead when converting from and to GMP in
        most cases.

        Loading the test module in test/data/emacs-module and evaluating

        (dotimes (_ 10000)
          (mod-test-double (* 2 most-negative-fixnum)))

        under Callgrind shows that on my (GNU/Linux) machine Emacs only spends
        10% of the CPU time of mod-test-double in mpz_import and mpz_export
        combined, even though that function does little else.  (By contrast,
        30% is spent in allocate_pseudovector.)

        * src/emacs-module.h.in: Don't check EMACS_MODULE_GMP.  Don't include
        gmp.h.  Remove emacs_mpz structure.  Instead, define type alias
        emacs_limb_t and macro EMACS_LIMB_MAX.

        * src/module-env-27.h: Change interface of extract_big_integer and
        make_big_integer to take a sign-magnitude representation instead of
        mpz_t.

        * src/emacs-module.c: Don't check EMACS_MODULE_GMP or
        EMACS_MODULE_HAVE_MPZ_T.  Add a comment about the chosen
        implementation.
        (module_extract_big_integer, module_make_big_integer): Reimplement
        without using mpz_t in the interface.

        * doc/lispref/internals.texi (Module Values): Adapt function
        documentation and example.  Stop mentioning GMP and EMACS_MODULE_GMP.

        * test/data/emacs-module/mod-test.c: Don't define EMACS_MODULE_GMP or
        EMACS_MODULE_HAVE_MPZ_T.
        (memory_full, extract_big_integer, make_big_integer): New helper
        functions, identical to example in the Info documentation.
        (Fmod_test_nanoseconds, Fmod_test_double): Adapt to new interface.

        (message-sendmail-envelope-from): Use it.
        * lisp/mail/emacsbug.el (report-emacs-bug): Use it.

2019-12-03  Stefan Monnier  <monnier@iro.umontreal.ca>

        * lisp/minibuffer.el (completion-pcm--optimize-pattern): New function

        This fixes bug#38458 where a final `point` in the pattern prevented
        the expected normal behavior of point moving after the completion
        of the final implicit `any`.

        (completion-pcm--find-all-completions)
        (completion-substring--all-completions): Use it.
        (completion-basic--pattern): Don't both removing "" any more.
        (completion-basic-try-completion): Use it as well as
        `completion-basic--pattern`.

2019-12-03  Mattias Engdegård  <mattiase@acm.org>

        Avoid duplicated character classes in rx

        For example, (any digit digit) should produce "[[:digit:]]",
        not "[[:digit:][:digit:]]".

        * test/lisp/emacs-lisp/rx-tests.el (rx-any): Add test case.

2019-12-02  Tobias Bading  <tbading@web.de>  (tiny change)

        Fix incorrect GTK menus on HiDPI monitors with scaling factor > 1

        This should fix Bug#31223, Bug#28106, Bug#23672 as well as Ubuntu bug
        https://bugs.launchpad.net/ubuntu/+source/emacs25/+bug/1695228

        Also fixes the formerly unscaled Y value returned by
        frame-monitor-workarea (and display-monitor-attributes-list).

        For details on why some GTK menus were empty please see thread
        https://lists.gnu.org/r/emacs-devel/2019-11/msg01061.html

        * src/gtkutil.c (menubar_map_cb, xg_update_frame_menubar): Scale up
        req.height so that the menu bar's height is in device pixels as
        expected.
        (xg_event_is_for_menubar): Scale down rec.x and rec.y so that
        gtk_widget_intersect() works as intended.
        * src/xfns.c (Fx_display_monitor_attributes_list): Scale work.x and
        work.y up to be in device pixels.

2019-12-01  Juanma Barranquero  <lekktu@gmail.com>

        ibuf-ext.el: Fix previous change

        * lisp/ibuf-ext.el (ibuffer-generate-filter-groups): Use
        `cl-destructuring-bind' instead of `cl-multiple-value-bind', as we
        don't want to assume how multiple-values are implemented, and we
        know a list is being returned anyway.  Suggested by Stefan Monnier.

2019-12-01  Dmitry Gutov  <dgutov@yandex.ru>

        * lisp/vc/diff-mode.el (diff-context): Set 'extend t' (bug#37774).

        Enable transient-mark-mode during selection (bug#38431).

2019-12-01  Michael Albinus  <michael.albinus@gmx.de>

        Suppress superfluous messages in tramp-tests

        * test/lisp/net/tramp-tests.el (tramp-test10-write-region)
        (tramp-test10-write-region-file-precious-flag)
        (tramp-test34-connection-local-variables)
        (tramp-test36-vc-registered): Let-bind `inhibit-message'.

2019-12-01  Juanma Barranquero  <lekktu@gmail.com>

        ibuffer-mark-by-content-regexp: don't depend on `cl-some'

        * lisp/ibuf-ext.el (ibuffer-mark-by-content-regexp): Use `cl-dolist'
        instead of `cl-some' to avoid a run-time dependency on cl-lib that
        triggers an unreported bug similar to bug#38430.

2019-12-01  Juanma Barranquero  <lekktu@gmail.com>

        ibuffer-do-isearch: don't depend on `cl-values-list' (bug#38430)

        * lisp/ibuf-ext.el (ibuffer-generate-filter-groups): Don't call
        `cl-values-list'.  Our implementation of that function just
        checks that its argument is a list, and then returns it.  In
        this specific case, the argument is guaranteed to be a list.

2019-11-30  Mattias Engdegård  <mattiase@acm.org>

        Improved mouse rectangle selection robustness (bug#38013)

        Make the rectangular selection work better with
        display-line-numbers-mode and side-by-side windows.
        Also make the mouse track the text cursor in a consistent way.

        * lisp/mouse.el (mouse--rectangle-track-cursor): Added constant.
        (mouse-drag-region-rectangle): Take the line-number width into
        account, and use window-relative columns.  Track either the cursor or
        rectangle corner with more care.

2019-11-30  Juri Linkov  <juri@linkov.net>

        * lisp/tab-line.el (tab-line-auto-hscroll): Don't let-bind buffer-local values

        Use setq to set buffer-local values of truncate-lines and buffer-undo-list.
        This will prevent leaking of let-bound values to buffer-local values
        of the minibuffer.

2019-11-30  Juri Linkov  <juri@linkov.net>

        * lisp/gnus/gnus-win.el (gnus-configure-frame): Check for window-live-p.

        * doc/misc/gnus.texi (Tabbed Interface): New node.  (bug#37998)

2019-11-30  Juri Linkov  <juri@linkov.net>

        * lisp/subr.el: Add discard-input to more functions.

        * lisp/subr.el (read-char-from-minibuffer-insert-other)
        (y-or-n-p-insert-other): Use discard-input in case of user mistake.
        (do-after-load-evaluation): Add discard-input before calling 'message',
        so in case of the active minibuffer, calling minibuffer-message will allow
        sit-for to wait the complete timeout, because discard-input will discard
        all initial events that prevent sit-for from waiting during startup.

        CC Mode.  Fix fontification bug with unterminated quotes on adjacent lines

        In particular, with these unterminated quotes on each of two adjacent lines,
        the following text was spuriously fontified with string face.

        * lisp/progmodes/cc-defs.el
        (c-search-backward-char-property-with-value-on-char): New macro.

        * lisp/progmodes/cc-mode.el (c-clear-string-fences): Check whether there is an
        unmatched quote at a lower buffer position which should match the current
        quote, rather than wrongly assuming the latter is unmatched and marking it
        with a punctuation syntax.
        (c-font-lock-fontify-region): Ensure all pertinent parts of the buffer have
        string fence properties applied before performing any syntactic operations on
        it; in particular, this applies to a quote at an earlier buffer position which
        "matches" one inside the region about to be fontified.

2019-11-30  Juri Linkov  <juri@linkov.net>

        * lisp/image.el: Support image scaling with mouse in other buffer.

        * lisp/image.el (image-increase-size, image-decrease-size):
        Add optional arg position.
        (image-mouse-increase-size, image-mouse-decrease-size):
        Use '(point-marker)' for arg position.
        (image--get-image): Use get-char-property from position if non-nil,
        and its buffer.
        (image--get-imagemagick-and-warn, image--change-size):
        Add optional arg position.

        * lisp/image.el (image-increase-size, image-decrease-size):
        Use run-with-idle-timer.
        (image--change-size): Rename back from image--change-size-function.

        * lisp/image-mode.el (image-mode--setup-mode): Remove hooks
        window-size-change-functions and window-selection-change-functions (bug#32672)
        (image-fit-to-window): Rename from image--window-change-function.
        (image--window-state-change): Rename from image--window-change.
        Use run-with-idle-timer.

        Fix image scaling with masks (bug#38109)

        * src/image.c (lookup_image): Move call to image_set_transform after
        postprocess_image.
        (image_create_x_image_and_pixmap_1): Use new function.
        (image_set_transform): Apply the transform to the mask too.
        (x_create_xrender_picture): New function.
        (Create_Pixmap_From_Bitmap_Data):
        (xpm_load): Use new function.
        * src/xterm.c (x_composite_image): Use PictOpOver when there is a mask
        so the transparency is honoured.
        (x_draw_image_foreground_1): Use x_composite_image.

2019-11-29  Stefan Monnier  <monnier@iro.umontreal.ca>

        * lisp/gnus/gnus.el (gnus-info): Define with `cl-defstruct`

        This makes the accessors into (inlined) functions (instead of macros),
        which simplifies some uses, and it makes the gnus-info-set-<foo>
        macros redundant since we can use `setf` instead.  Remove them and
        update all users.

        (gnus-info-group, gnus-info-rank, gnus-info-read, gnus-info-marks)
        (gnus-info-method, gnus-info-params): Auto-defined by defstruct.
        (gnus-info-level, gnus-info-score): Define as a function.  Add gv-setter.
        (gnus-info-set-group, gnus-info-set-rank, gnus-info-set-read): Remove,
        use `setf` instead.
        (gnus-info-set-marks, gnus-info-set-method, gnus-info-set-params):
        Define as a function.
        (gnus-info-set-entry): Delete function.
        (gnus-info--grow-entry): New function, extracted from it.
        (gnus-info--set-level, gnus-info--set-score): New functions, extracted
        from the `gnus-info-set-level` and `gnus-info-set-score` which they replace.
        (gnus-get-info): Define as a function.

        * lisp/gnus/gnus-group.el (gnus-group-edit-group-done):
        Use the `extend` arg of `gnus-info-set-method`.
        (gnus-group-sort-selected-flat): eta-reduce.

        * lisp/textmodes/mhtml-mode.el: Fix bug#38372

        The `sgml-syntax-propertize-rules` rely on the `sgml--syntax-propertize-ppss`
        setup by `sgml-syntax-propertize` so it is not correct/safe to use
        them directly like html used to do.

        Change `sgml-syntax-propertize` so it can be used by mhtml,
        and then adjust mhtml-mode accordingly.

        * lisp/textmodes/mhtml-mode.el: Remove redundant `eval-and-compile`.
        Only require cl-lib at compile-time.
        (mhtml--syntax-propertize): New const, extracted from mhtml-syntax-propertize.
        (mhtml-syntax-propertize): Use `sgml-syntax-propertize`.

        * lisp/textmodes/sgml-mode.el (sgml--syntax-propertize): New const,
        extracted from sgml-syntax-propertize.
        (sgml-syntax-propertize): Add optional `rules-function` arg.

        Fix MS-Windows build with mingw.org's MinGW

        mingw.org's MinGW by default targets Windows 9X, so
        _WIN32_WINNT is set to a value that bypasses declarations
        in system headers we need to compile network_interface_list.
        Also, the code needed a workaround for Windows XP, where
        some functionality is missing from the GetAdaptersAddresses
        API.

        Make auth-source-pass-search understand port lists

        For cases such as a typical IMAP Gnus setup, auto-source-pass-search
        is passed a list of "port aliases" like (993 "imaps" "imap" "993"
        "143") in hopes of finding a matching ~/.password-store entry.

        This modification makes this library understand and unroll the port
        list so that, i.e. "domain:993", "domain:imaps"", "domain:imap",
        etc. are computed as potential suffixes.  Previously a nonsensical
        string "domain:(993 imaps imap ...)" was returned.

        argument instead of using `so-long-menu-item-replace-action'.

        * lisp/so-long.el (so-long): Firstly revert the existing action, if any

        This makes `so-long' consistent with the action commands in the menu.

        If multiple actions were to be layered on top of one another, we would
        lose the ability to revert to the normal state.  Custom actions
        combining multiple other actions can be defined if necessary.

        afterwards, whereas the old code did not; but that is not a problem.
        (so-long-menu-click-window, so-long-menu-item-revert): Remove the

        Make icomplete-tidy-shadowed-file-names less aggressive

        When using this option and editing input, some transient situations
        may arise that lead to file-name shadowing, but that shouldn't
        necessarily lead to auto-delete behaviour, which will be surprising.

        In '/foo/x/bar', if the user deletes the 'x', shadowing occurs, but
        probably shouldn't.  So, somewhat like ido-mode, only auto-tidy
        shadowed file names if the user is inserting text at end of input.

        * lisp/icomplete.el (icomplete-exhibit): Check this-command.

        Port hexdigit init to non-GCC + pdumper

        The old code assumed that hexdigit initialization (needed by
        non-GCC) could be done in syms_of_character, but that is no longer
        true with pdumper.  Instead, simplify hexdigit init so that it can
        be done statically on all C99 platforms.  Problem discovered on
        Solaris 10 sparc + Oracle Solaris Studio 12.6.
        * src/character.c (hexdigit): Add 1 to every value; all uses
        changed.  This simplifies the initialization so that it can be
        done statically on any C99 compiler.  hexdigit is now always const.
        (syms_of_character): Omit no-longer-necessary initialization.
        * src/character.h (HEXDIGIT_CONST, HEXDIGIT_IS_CONST):
        Remove.  All uses removed.

        (repos-count-screen-lines): Narrow without changing point-min

        * lisp/reposition.el (repos-count-screen-lines): Narrow without
        changing point-min.  It wasn't necessary for vertical-motion to
        work, and it had some adverse effects on how font-lock rules were
        applied
        (https://lists.gnu.org/r/emacs-devel/2019-11/msg00522.html).
        This can also be an alternative fix for bug#38049.

        (c-remove-stale-state-cache, c-remove-stale-state-cache-backwards): Instead of

        consing.
        (c-parse-state-1): Call c-state-cache-lower-good-pos rather than

        an earlier version, as well as making provisions for doing likewise
        following any incompatible changes arising in future versions.

2019-11-14  Phil Sainty  <psainty@orcon.net.nz>

        Backwards-compatibility function definitions for so-long.el

        (so-long-make-buffer-read-only, so-long-revert-buffer-read-only)
        (so-long-inhibit-global-hl-line-mode): Restore dummy definitions of
        now-obsolete hook functions used by earlier versions of so-long.el,

        * test/lisp/so-long-tests/so-long-tests.el:
        Support for so-long-deferred.

        Pre-existing tests have been updated to ensure the buffer is already
        displayed in cases where a call to `normal-mode' is the (potential)
        trigger for `so-long'.

        Avoid fido-mode's setup on non-icomplete minibuffers

        Otherwise we would lose things like C-r (isearch-backward) when doing

        * lisp/icomplete.el (icomplete--fido-mode-setup): Restrict setup
        to when icomplete-mode really kicks in.

        Conditionally omit edition numbers, dates in doc

        This redoes the 2019-11-02T00:24:02!eggert@cs.ucla.edu patch,
        updated after consultation with John Sullivan.
        Omit printed edition numbers in online manuals while keeping
        them in printed manuals.  In online manuals the edition
        numbers seem to cause more confusion than they cure; e.g.,
        https://shop.fsf.org/books/gnu-emacs-manual-18th-edition-v-261
        currently advertises "18th edition" even as it points to
        https://www.gnu.org/software/emacs/manual/pdf/emacs.pdf which
        says "Seventeenth Edition".  It is simpler and less confusing
        to stick to one version number like "27.0" in online manuals.
        For printed manuals people can run, e.g., "texi2any -D
        'EDITION Nineteenth'" when generating the 19th printed edition
        of the Emacs manual.
        * doc/emacs/emacs.texi (EDITION):
        * doc/lispintro/emacs-lisp-intro.texi (edition-number, update-date):
        * doc/lispref/elisp.texi (VERSION, DATE):
        Remove definitions.  Instead, let the person printing the book
        specify these values, with the default being the online version
        which does not have printed edition numbers.
        * doc/lispintro/emacs-lisp-intro.texi (titlepage-edition-number):
        New flag, for the edition number as it appears on the title page.

        might use some floating-point format other than IEEE format, as
        Emacs currently assumes IEEE in several places and there seems

        * lisp/autorevert.el: Use 'minibuffer-message' to not obscure the prompt.

        * lisp/autorevert.el (auto-revert-handler): Use 'minibuffer-message'
        instead of 'message'.  Call it from the original window's buffer
        that in case of the minibuffer should be current, so
        minibuffer-message could add a message to it.  (Bug#34614)

        * lisp/emacs-lisp/ert-x.el (ert--make-message-advice): Add nil to
        the list of values to not use for format-message, because

        Allow flymake diagnostic types to have shorter names

        Eglot, a third-party package which uses Flymake, has its own
        diagnostic types such as 'eglot-error', 'eglot-warning', etc...  While
        not being too long, they will not fit in the type column of the "list
        all diagnostics" buffer.  This commit allows diagnostic types to have
        user-defined names and also assigns names to the default categories.

        Fix icomplete-force-complete-and-exit for no-input situations

        If there is no minibuffer input, but the user has already cycled some
        pre-calculated completions, we should be calling
        minibuffer-force-complete-and-exit instead of
        minibuffer-complete-and-exit.  The former is guaranteed to be fast in
        this situation and yields the desired "selected" completion, while the
        latter will just give us the default, ignoring all the cycling of
        icomplete-{forward|backward}-completions.

        Omit edition numbers and dates in manuals

        These seem to cause more confusion than they cure; e.g.,
        https://shop.fsf.org/books/gnu-emacs-manual-18th-edition-v-261
        currently advertises "18th edition" even as it points to
        https://www.gnu.org/software/emacs/manual/pdf/emacs.pdf
        which says "Seventeenth Edition".  It is simpler and less
        confusing to stick to one version number like "26.3".  If we
        need a separate edition number for each printed manual for
        some reason (marketing?) we can put “@ifset printed-edition”
        around anything specific to the printed editions.
        (as opposed to online PDF copies).

        Inhibit undo-in-region for mouse-drag-region (bug#37700)

        'mouse-drag-region' leaves the region active around the dragged text,
        so a straight undo did not revert the entire operation.  To remedy
        this, inhibit undo-in-region when the last command was
        mouse-drag-region.  (Method suggested by Stefan Monnier.)

        * lisp/mouse.el (undo-drag-region): Set the undo-inhibit-region property.
        * lisp/simple.el (undo): Inhibit undo-in-region if the last command
        had the undo-inhibit-region property set.
        * doc/lispref/symbols.texi (Standard Properties):
        * doc/lispref/text.texi (Undo): Document undo-inhibit-region.

        This adds create/snapshot bindings to the stash button even when there

        * etc/NEWS: Announce the bindings.

        * lisp/vc/vc-git.el (vc-git-stash-shared-map): New keymap.  Holds

        Fix print.c infloop on circular lists

        Fix infinite loops in print.c when a circular list is passed
        to command-error-default-function or to error-message-string.
        * src/print.c (print_error_message):
        Use FOR_EACH_TAIL to avoid infloop on circular lists.
        (print_object): Use FOR_EACH_TAIL_SAFE, as it uses
        Brent’s teleporting tortoise-hare algorithm which is
        asymptotically better than the classic tortoise-hare
        algorithm that the code wsas using.
        * test/src/print-tests.el (print-circle-2): When print-circle
        is nil, do not insist on a particular cycle-detection heuristic.
        (error-message-string-circular): New test.

        Fix infinite loops in keyboard.c when a circular list is
        found in a hook, or in help-event-list, or in the argument
        of event-convert-list, or in a keymap where a Lucid event
        type list is expected, or in a menu or tab spec.
        * src/keyboard.c (safe_run_hooks_error, menu_bar_items)
        (parse_menu_item, parse_tab_bar_item, parse_tool_bar_item):
        Use FOR_EACH_TAIL to avoid infloop on circular lists.
        (help_char_p, Fevent_convert_list, lucid_event_type_list_p):
        Use FOR_EACH_TAIL_SAFE to avoid infloop on circular lists,
        when the action is idempotent so a circular list can be
        treated as a noncircular one.

        write-region-annotate-functions.
        * src/fileio.c (Finsert_file_contents, build_annotations):
        Use FOR_EACH_TAIL to avoid infloop on circular lists.
        (build_annotations): Use an EMACS_INT, not an int, to count
        nesting level.
        * test/src/fileio-tests.el:
        (fileio-tests--circular-after-insert-file-functions): New test.

2019-10-30  Lars Ingebrigtsen  <larsi@gnus.org>

        Revert "Move description of value to syntax-ppss function."

        This reverts commit 305dbc7e2be05748039aacb1a3d697f6f64bed4c.

        Both of the functions in question are used a lot in the sources, so move it back to the more basic function.

        Tweak fontification of \url{http://foo.org/bar%zot} in (la)tex-mode

        * lisp/textmodes/tex-mode.el (tex-font-lock-keywords-1):
        \url{http://foo.org/bar%zot} shouldn't be fontified as having a
        comment, so make the tex-verbatim face overwrite the
        already-applied syntactical comment bits (bug#37134).

2019-10-30  Lars Ingebrigtsen  <larsi@gnus.org>

        Bind vc-git-stash to a key

        * lisp/vc/vc-git.el (vc-git-stash-map): Give `vc-git-stash' a
        keystroke, because it's a useful command.

        When there are no stashes, there's no way to use that keystroke (since
        it's only bound on the stash lines), so perhaps that should also be
        fixed somehow.

2019-10-30  Lars Ingebrigtsen  <larsi@gnus.org>

        Clear more data in font-lock-refontify to ensure refontifying

        font-lock \ #foo in shell mode more correctly

        * lisp/progmodes/sh-script.el (sh-syntax-propertize-function):
        \ #foo isn't a comment -- it's a symbol that starts with a space
        character (bug#17538).

2019-10-30  Lars Ingebrigtsen  <larsi@gnus.org>

        Make font-lock-refontify try even harder to refontify

        even after switching global font lock mode on and then off again.

2019-10-30  Lars Ingebrigtsen  <larsi@gnus.org>

        Fix setgid fontification in dired on some OS-es

        * lisp/dired.el (dired-font-lock-keywords): Apparently some
        versions of ls use "S" for setgid and other use "s" (bug#8186).

2019-10-30  Lars Ingebrigtsen  <larsi@gnus.org>

        Fix "dnl" highlights in m4-mode

        * lisp/progmodes/m4-mode.el (m4-font-lock-keywords): "dnl"
        comments should override any previous syntax-based highlighting
        (37132).  This makes "dnl foo#bar" be highlighted correctly.

2019-10-30  Lars Ingebrigtsen  <larsi@gnus.org>

        Move description of value to syntax-ppss function.

        * lisp/emacs-lisp/syntax.el (syntax-ppss): Move the description of
        the return value from...

        * src/syntax.c (Fparse_partial_sexp): ... here because
        `syntax-ppss' is what's called over the place, and jumping through
        an indirection to get to the value description is inconvenient.

2019-10-30  Lars Ingebrigtsen  <larsi@gnus.org>

        sensible feedback to the user.

        Optimize conditional recursive merge face.

        * src/xfaces.c (merge_face_vectors) : Pass ATTR_FILTER to
        merge_face_ref to stop recursion merging in advance when possible.
        (merge_named_face) : add more conditions to potentially reduce calls to
        merge_face_vectors in more unneeded situations.

2019-10-29  Jimmy Aguilar Mena  <spacibba@aol.com>

        Fix extend face in gui interfaces.

        Make icomplete-exhibit actually work when navigating up directories

        Sometimes, when finding files with icomplete-mode, backward-deleting
        the previous word or sexp (to move up a directory) doesn't actually
        refresh the file list of the new directory.  Forcing redisplay in
        icomplete-exhibit misteriously fixes the problem.

        * lisp/icomplete.el (icomplete-exhibit): Add call to redisplay.

2019-10-28  João Távora  <joaotavora@gmail.com>

        New commands for making icomplete behave more like ido

        This tries (not particularly hard) to emulate Ido's magic C-k, C-d,
        RET and DEL.  For now, the new commands have to be explicitly added to
        an active map by the user, using something like this:

        (let ((imap icomplete-minibuffer-map))
          (define-key imap (kbd "C-k") 'icomplete-magic-ido-kill)
          (define-key imap (kbd "C-d") 'icomplete-magic-ido-delete-char)
          (define-key imap (kbd "RET") 'icomplete-magic-ido-ret)
          (define-key imap (kbd "DEL") 'icomplete-magic-ido-backward-updir))

        * lisp/icomplete.el (icomplete-magic-ido-kill)
        (icomplete-magic-ido-delete-char, icomplete-magic-ido-ret)
        (icomplete-magic-ido-backward-updir): New commands.

2019-10-27  João Távora  <joaotavora@gmail.com>

        Optimize lisp/icomplete.el when default completion available

        Often, when using icomplete with icomplete-show-matches-on-no-input
        and commands like C-h f, icomplete-exhibit will take a long time (like
        several seconds) to show all the completions.

        However, if there is a non-nil default value, like when the C-h f is
        performed exactly on a function name, the minibuffer prompt will
        reflect that immediately.  If the user immediately presses RE
        (icomplete-force-complete-and-exit) we take that to mean "use the
        default" and avoid the long wait.

        As an extra performance tweak, this commit also removes an unneeded
        call to icomplete-exhibit in icomplete-minibuffer-setup.

        * lisp/icomplete.el (icomplete-force-complete-and-exit): Short-circuit
        possibility of non-nil minibuffer-default.
        (icomplete-minibuffer-setup): No need to explicitly icomplete-exhibit

        Improve scoring algorithm for flex-style completions

        The previous algorithm had two problems: it considered non-matches in
        the beginning and end of the string as matching "holes" and failed to
        penalize larger holes, making flex-score-match-tightness only
        effective in some corner cases.

        The new formula, which is described in code and in pseudo-code in the
        comments, fixes these problems.

        As a result, by default, C-h f flex now correctly bubbles up
        "company-search-flex-regexp" to the top, in front of "file-exists-p".
        With a flex-score-match-tightness smaller than 1.0, the situation is
        reversed.

        * lisp/minibuffer.el (flex-score-match-tightness): Adjust default

        Allow completion styles to adjust completion metadata

        This commit re-does the now-reverted commit with the same title.  That
        version relied on generic functions, which cannot be used yet in files
        such as lisp/minibuffer.el.  This version uses a symbol property
        completion--adjust-metadata instead.

        The new facility allows completion styles to have a say in metadata
        properties such as cycle-sort-function and display-sort-function.
        This is especially useful for completion styles such as 'flex', which
        generally produce many matches, including some potentially "obscure"
        ones.  The default sorting strategy would often bubble the latter to
        the top of the list.

        The sorting function for 'flex' considers pre-computed matching scores
        and is thus much better than the default for this particular style.

        Additionally, it overrides the completion table's cycle-sort-function
        or display-sort-function properties if they exist, although it still
        uses them to pre-sort the result, so that they are still relevant for
        resolving ties.

        * lisp/minibuffer.el (completion--nth-completion)
        (completion--flex-adjust-metadata): New helper.

        Replay key if kboard is interrupted while initializing (Bug#37782)

        The problem with the original fix for bug#5095 is that it drops

        Thus, the first ESC character sent by the terminal after turning
        on focus tracking is lost and we get '[' and 'I' events separately

        * lisp/emacs-lisp/rx.el (rx--translate-symbol):

        stack space.  For example, (0+ anychar) now matches strings of any
        size (bug#37659).

        Fix python-shell font-lock cleanup for unclosed quotes (Bug#32390)

        The problem originating this report was:

        -------------
        In [15]: "
          File "<ipython-input-15-3b7a06bb1102>", line 1
            "
             ^
        SyntaxError: EOL while scanning string literal

        In [16]:   string face still here"
        -------------

        This happens because
        python-shell-font-lock-comint-output-filter-function is called twice,
        first for the error output and then for the "In [16]: " part.  The
        first time python-shell-comint-end-of-output-p returns nil since
        we're *not* at the end of an input prompt.  The second time it returns
        0 since we're at the end of *just* an input prompt.  So we don't call
        python-shell-font-lock-cleanup-buffer either time.

        The current code is relying in a very weak rule: it considers "just an
        input prompt" to be a continuation prompt.  Another unreliable aspect
        of the current rule is that sometimes

            (python-shell-comint-end-of-output-p (ansi-color-filter-apply output))

        returns 1 and not 0 for continuation prompts.  In short, the rule does
        a very poor job identifying continuations.

        * lisp/progmodes/python.el (python-shell-font-lock-cleanup-buffer):
        Don't check for empty OUTPUT since python-shell-comint-end-of-output-p
        returns nil for that anyway.  Don't check for
        python-shell-comint-end-of-output-p returning a specific number
        because it's unreliable, just check for any non-nil.  Identify
        continuation prompts by looking for "...".

        (iso8601-parse-date):
        Don’t bother to separate the year’s sign from the year,
        as that distinction is not needed: ISO 8601 uses
        astronomical year numbering with a year zero, which
        is what the Emacs time functions use, so there’s no
        need to treat nonpositive years specially.
        (iso8601--adjust-year): Remove; no longer needed
        since callers can just use string-to-number.
        * test/lisp/calendar/iso8601-tests.el (test-iso8601-date-years):
        Adjust test case to match fixed behavior.

        Fix linear equation system solving in Calc (bug#35374)

        * lisp/calc/calcalg2.el (math-try-solve-for):
        To solve Ax^n=0 where A is a nonzero constant and x the variable to
        solve for, solve x^n=0 instead of solving A=0 (which obviously fails)
        or something equally stupid.
        * test/lisp/calc/calc-tests.el (calc-test-solve-linear-system): New.

        Update some URLs

        This mostly changes http: to https: in URLs.  It also updates
        some URLs that have moved, removes some URLs that no longer
        work, recommends against using procmail (procmail.org no
        longer works), and removes some mentions of the
        no-longer-existing Gmane, LPF and VTW.
        It doesn't update all URLs, just the ones I had time for.

        Expand time-stamp unit tests to cover all formatting options

        * test/lisp/time-stamp-tests.el: Expand unit tests to cover all formatting options.
        These tests validate time-stamp-pattern formatting that has existed
        since at least Emacs 22 (released in 2007).  The tests cover both
        documented behavior and behavior implemented to support future migrations.

        * test/lisp/time-stamp-tests.el (time-stamp-string): Add a second argument (TIME) to
        open a testing seam.  Have the unit tests call this public function.

        * test/lisp/time-stamp-tests.el (time-stamp-string, time-stamp-string-preprocess):
        Remove the second pass through time-string--format.  (Previously both
        functions called it.)  It was used only to handle "%", but this is now
        handled by having time-stamp-string-preprocess not double it.
        Not doubling the "%" in time-stamp-string-preprocess fixes the padding
        of "%2%", which was discovered by the new unit tests to be wrong.

        Make js-jsx-regexps case-sensitive

        The regexp in this list used a capitalized “React” because it actually
        should be capitalized like that.  Otherwise, the following code would

        file were missing.
        * src/fileio.c (Ffile_newer_than_file_p): Use file_attribute_errno
        not file_test_errno, since returning nil is not appropriate when
        there are two files to test; e.g., in the rare cases where both
        file timestamps have overflowed then neither t nor nil is correct.

        * lisp/gnus/message.el (message-make-forward-subject-function): Change
        default value to be a list so it's easier for users to add

        * doc/misc/tramp.texi (Inline methods) <sshx, plink, plinkx>:
        (External methods) <scpx, pscp, psftp>: Mention, that the remote
        login shell could be changed.
        (Remote shell setup): Remove description of properties
        "remote-shell-login" and "remote-shell-args", they don't matter
        here.  Changing the default remote shell works only for some
        methods.
        (Frequently Asked Questions): Refer to alternative approach fixing
        zsh problems.

        * etc/NEWS: Some Tramp methods allow to change the remote login shell.

        * lisp/gnus/gnus-registry.el (gnus-registry-article-marks-to-chars):
          (gnus-registry-article-marks-to-names): In some circumstances it's
          possible for the user's summary line format spec to include
          registry-specific code, while the registry itself isn't actually
          loaded. Make sure the database is actually a hashtable before

        Omit some overenthusiastic file-truename calls

        Problem reported by Tino Calancha (Bug#37445).
        * src/emacs.c (init_cmdargs): Call file-truename only if
        needed, i.e., if invocation-directory ends in "/i386/" on
        WINDOWSNT.
        * src/lread.c (readevalloop): If the sourcename is not
        absolute, make it absolute.  There is no need to convert
        non-absolute files into truenames, since absolute files are
        not converted into truenames.
        (init_lread): Do not convert source-directory into a truename
        at startup.  There is no need to do so in a dumped Emacs since
        an absolute file name suffices.  The source directory might
        not even exist any more, or might have been replaced by an
        interloper who takes advantage of the truename calculation.
        (syms_of_lread): Remove Qfile_truename; no longer needed.

2019-09-18  Matt Bisson  <mbisson@vmware.com>  (tiny change)

        Fix ignored Motif scrollbar resources (Bug#37359)

        * src/xterm.c (x_create_toolkit_scroll_bar): On Motif
        scrollbars, "foreground" has no meaning, while "background"
        means the truck and arrow colors, and "trough" means the
        background of the entire widget.  This fix hooks up the Emacs
        scrollbar "foreground" color to the XmNbackground resource
        and the "background" color to XmNtroughColor which is more in
        line with how Xaw scrollbars behave.

        in isearch-lazy-highlight-timer to cancel it in lazy-highlight-cleanup.

        (isearch-done): No need to set isearch-lazy-highlight-start to nil -
        it used to reset lazy-highlight loop like isearch-lazy-highlight-window-start,
        but now other packages set isearch-lazy-highlight-last-string to nil to reset

        Out-of-datedness .elc check is merely a file test

        * src/fileio.c (file_test_errno): Now extern.

        Improve reporting of I/O, access errors

        Signal an error for file-oriented errors that are not tame
        errors like ENOENT and ENOTDIR (Bug#37389).
        Do this for primitives exposed to Lisp; the lower
        level internal C API merely makes errno values available
        to higher-level C code.
        * doc/lispref/files.texi (Testing Accessibility)
        (File Attributes, Extended Attributes): Do not say that the

        (emacs_readlinkat): Now static.
        * src/filelock.c (current_lock_owner, lock_if_free): Return a
        positive errno on error, and the negative of the old old value
        on success.  All callers changed.
        * src/lread.c (openp): Propagate serious errno values to caller.

        Updated to match more recent versions of Praat.

        * lisp/leim/quail/ipa-praat.el ("ipa-praat"): Update to match
        more recent versions of Praat (bug#36198).

        - \rh was used for ram's horns (a vowel) and rhoticity hook (a
          diacritic).  Praat uses \hr for the hook, so I made that changed.

        - \e3v for the slightly rounded diacritic seems to have been a typo
          related to the use of e in the example.  Changed it to \3v to match
          Praat.

        - Added examples to the table of tone diacritics

        - Added \^h for superscript h

        - Added \^H for superscript h with hook

        - Added \^w for superscript w (labialization)

        - Added \^j for superscript j (palatalization)

        - Added \^g for superscript symbol (velarization)

        - Added \^9 for superscript symbol (pharyngealization)

        match_data.known_fonts if the font spec includes :script that
        names one of the non-USB scripts.
        (add_font_entity_to_list): If font_matches_spec returns zero
        for a font, and we have some fonts in match_data->known_fonts,
        consider the font to be a match if it is named in known_fonts.
        (font_supported_scripts): Update the Unicode Subranges.  In
        particular, map bit 74 to 'burmese', as this is the name Emacs
        uses, not 'myanmar'.  Add a list of scripts that have no USBs
        defined for them.
        (syms_of_w32font) <Qburmese, Qcuneiform_numbers_and_punctuation>

        it keeps other-write but disables other-execute permissions.
        3949 (#o7555) was intended here.  Use octal notation for clarity.

        broken out of Ffile_name_directory.
        (file_name_case_insensitive_err, Ffile_writable_p, Fdo_auto_save):
        Use it.
        (file_name_case_insensitive_err): Rename from
        file_name_case_insensitive_p.  Accept an unencoded Lisp_Object
        rather than an encoded char *, so that platforms other than
        Cygwin and macOS need not encode the file name.  Return an int
        -1, 0, errno rather than a bool (setting errno if false),
        so that the caller can distinguish an error from false.
        All callers changed.
        (Ffile_name_case_insensitive_p): Don’t issue system calls on
        platforms other than Cygwin and macOS.  Fix bug that broke the
        attempt to move up the filesystem tree (it moved up only one
        level).

        Improve gc-cons-percentage calculation

        The old calculation relied on a hodgpodge of partly updated GC
        stats to find a number to multiply gc-cons-percentage by.
        The new one counts data found by the previous GC, plus half of
        the data allocated since then; this is more systematic albeit
        still ad hoc.
        * src/alloc.c (consing_until_gc, gc_threshold, consing_threshold):
        Now EMACS_INT, not intmax_t.
        (HI_THRESHOLD): New macro.

        (make_interval, allocate_string, allocate_string_data)
        (make_float, free_cons, allocate_vectorlike, Fmake_symbol): Use it.
        (allow_garbage_collection, inhibit_garbage_collection)
        (consing_threshold, garbage_collect):
        Use HI_THRESHOLD rather than INTMAX_MAX.
        (consing_threshold): New arg SINCE_GC.  All callers changed.
        (bump_consing_until_gc): Return new consing_until_gc, instead of
        nil.  All callers changed.  Don’t worry about overflow since we
        now saturate at HI_THRESHOLD.  Guess that half of
        recently-allocated objects are still alive, instead of relying on
        the previous (even less-accurate) hodgepodge.
        (maybe_garbage_collect): New function.
        (garbage_collect): Work even if a finalizer disables or enables
        memory profiling.  Do not use malloc_probe if GC reclaimed nothing.
        * src/lisp.h (maybe_gc): Call maybe_garbage_collect instead

        (free_cons, Fcons, setup_on_free_list)
        (allocate_vector_from_block, Fmake_symbol):
        Do not update gcstat, since it is for statistics from the most
        recent GC, not for a partially-updated hodgepodge.
        (sweep_vectors): Update gcstat, since setup_on_free_list
        no longer does.
        (garbage_collect_1): Rename to garbage_collect and adopt its API.
        Remove the old garbage_collect, which is no longer needed.
        All callers changed.

        Don't build print-number-table unless it will be used

        There are only a few users of print-number-table, and none of them use
        it when print-circle is nil.  A couple of them used to.  print_object
        was changed in 2012-04-20 "* src/print.c (print_preprocess): Only
        check print_depth if print-circle is nil".
        byte-compile-output-docform which uses print-number-table binds
        print-circle to t before printing unless
        byte-compile-disable-print-circle is set, but that variable has been
        marked obsolete since 24.1.

        * src/print.c (print_preprocess): Assert Vprint_circle is non-nil.
        Remove code handling the case when Vprint_circle is nil.
        (print, Fprint_preprocess): Don't call print_preprocess unless
        Vprint_circle is non-nil.
        (print_object): Remove comment referencing removed code in
        print_preprocess.

        Fix unnecessary hash table creation in cl-prin1 (bug#36566)

        cl-prin1 prints all its punctuation by passing strings to prin1.  When
        print-circle was set, print_preprocess was creating a new hash table
        for each string, causing excessive garbage collection when printing
        large Lisp objects with cl-prin1.

        * src/print.c (print_number_index): Fix typo in comment above.
        (PRINT_CIRCLE_CANDIDATE_P): Don't create print_number_table
        for top-level strings with no properties, except when
        print_continuous_numbering is on.

        (backtrace--with-output-variables): Bind print-gensym with value
        of :print-gensym found in view plist.

        Fix assertion violations due to non-ASCII text in menus

        * src/xdisp.c (tool_bar_height, redisplay_tool_bar)

        menu-bar or tool-bar window is multibyte, tell the display
        engine to treat it as multibyte, instead of relying on the
        initial determination by init_iterator (which is based on the
        multibyteness of the current buffer).  (Bug#37385)

        * lisp/progmodes/python.el (python-do-auto-fill): New function.
        (python-mode): Set it as normal-auto-fill-function, and don't set
        fill-indent-according-to-mode.  Having the latter set during
        fill-paragraph gives wrongs result, because python-indent-line doesn't
        remove indentation added by filling.
        * test/lisp/progmodes/python-tests.el (python-fill-docstring): New
        test.

2019-09-12  Stefan Monnier  <monnier@iro.umontreal.ca>

        * src/profiler.c: Leave `key` hashslots as Qunbound (bug#37382)

        Now that "key == Qunbound" is used to determine if a hash table entry
        is available, we can't stash pre-allocated vectors into the `key` slot
        anymore, so use the `value` slot instead.

        (make_log): Pre-fill the `value` slots i.s.o `key`.

2019-09-11  Paul Eggert  <eggert@cs.ucla.edu>

        Improve checking of pdump load failures

        * src/alloc.c (memory_full): Just report "memory exhausted" if
        failure occurs during initialization, since fancier recovery
        schemes are not likely to work when not initialized.
        * src/emacs.c (dump_error_to_string): Accept int, not enum
        pdumper_load_result, since the result might not fit in the
        enum.  Use strerror if it was derived from errno.  This is for
        better diagnostics of pdump load failures.
        (load_pdump_find_executable): Return char *, not enum.  2nd
        arg is now pointer to buffer size, rather than pointer to
        pointer to buffer.  All callers changed.  Use Emacs allocator
        since they should now be OK even during early startup.
        Use check_executable instead access, to use effective rather
        than real permissions.
        (load_pdump): Return void since callers ignore result.
        Use int where enum could be too narrow.  Use heap rather
        than stack for possibly-long string.  Prefer ptrdiff_t to
        size_t.
        * src/fileio.c (check_executable): Now extern.
        * src/pdumper.c (pdumper_load): Return int that may have
        errno added to it, for better diagnostics when loads fail.

        This reverts commit a59839d7556ef85058e09b005f0ff32e59b20ec3.
        This commit broke the MS-Windows build (because there's no

        to always signal an error on MS-Windows, the build fails.

        directly.  This results in `erc-lurker-state' being properly updated
        to keep track of non-lurkers, and thus `erc-lurker-p' returning

        Prefer functions to macros in buffer.h

        In buffer.h, prefer inline functions to function-like macros
        when either will do.  This helps avoid confusion about how
        many times an arg is evaluated.  On my platform, this patch
        improves performance of ‘make compile-always’ by 5.7%.
        Also, prefer enum constants to object-like macros

        Check instead of relying on NOTREACHED

        NOTREACHED was designed for traditional lint decades ago,
        and _Noreturn now normally subsumes its function.
        In the one case in Emacs where NORETURN might help and _Noreturn does
        not, check for NOTREACHED instead of assuming it.
        * lib-src/etags.c (main):
        * src/xterm.c (x_connection_closed):
        Remove NOTREACHED after a call to a _Noreturn function, as NOTREACHED
        is no longer needed there.  Also, one of the NOTREACHEDs was
        misplaced, which defeated traditional lint checking anyway.
        * lib-src/pop.c (pop_getline): Redo so as to not need NOTREACHED.
        * src/emacs.c (main): Use eassume (false) rather than NOTREACHED,
        so that running with ENABLE_CHECKING catches any internal error
        causing the toplevel Frecursive_edit to return.

        XDG_CONFIG_HOME, consistently with Emacs proper.  Caller changed.
        Use XDG convention if available, falling back on the old names
        if not.

2019-08-30  Paul Eggert  <eggert@cs.ucla.edu>

        Prefer ~/.config/emacs to ~/.emacs.d if neither exists

        That way, when Emacs starts in a fresh home directory,
        it prefers the new (XDG) convention rather than the old one.
        * lisp/files.el (locate-user-emacs-file): Make the parent
        directories of user-emacs-directory if needed.  This is useful
        if user-emacs-directory is "~/.config/emacs" and "~/.config"
        does not yet exist.
        * lisp/startup.el (command-line):
        * lisp/subr.el (user-emacs-directory):
        Prefer XDG_CONFIG_HOME to ~/.emacs.d if neither exists.

        Use XDG conventions more consistently

        Fit in better with the XDG conventions.
        Something like this was suggested in 2008 (Bug#583)
        and the XDG conventions seem to have settled down by now.

        just use the alt-file.
        (find-init-path): Remove; no longer used.
        (command-line): Don't check twice for XDG.
        Look at XDG_CONFIG_HOME instead of assuming it's ~/.config.
        Prefer XDG configuration if it exists; the user can disable
        this by setting XDG_CONFIG_HOME to some other place.

        Introduce new value t for compilation-context-lines to eliminate scrolling

        In particular, to prevent scrolling in a window lacking a left fringe.
        Instead, a visible arrow "=>" is inserted before column zero.  This fixes
        bug #36832.

        * lisp/progmodes/compile.el (compilation-context-lines): Add the new value t.
        (compilation-set-window): Amend to handle compilation-context-lines being t.

        property "=>".
        (compilation-set-overlay-arrow): New function which manipulates
        overlay-arrow-overlay.
        (compilation-goto-locus, compilation-find-file): In addition to calling
        compilation-set-window, also call compilation-set-overlay-arrow.

        * doc/emacs/building.texi (Compilation Mode): Document the new value t which
        compilation-context-lines can take.

        Fix a recent change in coding.c

        This partially reverts the changes in "extern function cleanup".
        * src/coding.c (encode_string_utf_8, decode_string_utf_8): Now
        extern again.  They should NOT be static, as they are intended
        to be used by the likes of json.c, where we need
        highly-optimized code for processing UTF-8 strings.  E.g.,
        decode_string_utf_8 beats make_string_from_utf8 by a factor of
        2 to 5 in a large number of scenarios.

        when either will do.

2019-08-24  Paul Eggert  <eggert@cs.ucla.edu>

        Speed up % and mod with fixnum denom

        * src/data.c (integer_remainder): New function.  When the
        numerator is a bignum and the denominator is small, this function
        uses mpz_tdiv_ui, which should be faster than mpz_tdiv_r.
        (Frem, Fmod): Use it.

2019-08-24  Paul Eggert  <eggert@cs.ucla.edu>

        Tweak integer mod performance

        * src/data.c (integer_mod): Use mpz_tdiv_r not mpz_mod, as that’s
        more similar to the fixnum case, is a bit more efficient, and
        otherwise the later ‘sgn_r < 0’ code is useless anyway.

2019-08-24  Paul Eggert  <eggert@cs.ucla.edu>

        Make (mod 1.0 0) consistent with (/ 1.0 0)

        * src/data.c (Fmod): Do not signal an error for (mod 1.0 0), for
        the same reason (/ 1.0 0) does not signal an error.
        * test/src/data-tests.el (data-tests-mod-0): New test.

        extern function cleanup

        Most of these functions can be static.  A few are unused.
        * src/coding.c (encode_string_utf_8, decode_string_utf_8):
        Define only if ENABLE_UTF_8_CONVERTER_TEST, as they're
        not needed otherwise.
        * src/coding.c (encode_string_utf_8, decode_string_utf_8):
        * src/data.c (integer_mod):
        * src/fns.c (base64_encode_region_1, base64_encode_string_1):
        * src/ftfont.c (ftfont_get_fc_charset):
        Now static.
        * src/sysdep.c (verrprintf): Remove; unused.

        :encrypt-then-mac only if the underlying GnuTLS library has
        the corresponding features.  This give the Elisp caller a bit
        more information about the peer status.
        * lisp/net/nsm.el (nsm-protocol-check--compression):
        Don’t worry about compression in newer GnuTLS versions
        that do not support compression.

        Print macro modified macro keys as characters not integers

        * lisp/macros.el (macros--insert-vector-macro): Pass all elements to

        which have modifier bits set wouldn't qualify otherwise).
        'prin1-char' will return nil if it can't handle the argument (e.g.,
        for symbols representing function keys).

        Rename renamed nsm.el variables and functions back

        * doc/emacs/misc.texi (Network Security): Start working on
        updating the NSM bits, but it's unclear how much of the new stuff
        to document.

        * lisp/net/nsm.el: Rename all nsm-tls-check-* functions to
        nsm-protocol-check--* to bring them back into line with the
        documentation.
        (network-security-protocol-checks): Renamed back again from
        `nsm-tls-checks', as this variable is documented and can't just go
        away.

2019-08-23  Lars Ingebrigtsen  <larsi@gnus.org>

        Move all NSM tests away from the `low' level

        * lisp/net/nsm.el (network-security-level, nsm-tls-checks): Make
        `low' a "check nothing" setting again, and move all the `low'
        checks back to `medium'.  This makes the test suite work again.

        Get the Gnutls code compiling on Fedora 30

        The recent changes caused the build to fail on Fedora 30 when built
        with --enable-gcc-warnings, among other things with diagnostics that
        gnutls_compression_get and gnutls_compression_get_name are deprecated
        (this started with GnuTLS 3.6).  Fix this by refusing to call these
        obsolescent and now-dummy functions in GnuTLS 3.6 and later.  However,
        this is just a temporary workaround to get the build working; a real
        fix is needed, as network-stream-tests fail.
        * src/gnutls.c (HAVE_GNUTLS_COMPRESSION_GET): New macro.
        (gnutls_compression_get, gnutls_compression_get_name):
        Define only if HAVE_GNUTLS_COMPRESSION_GET.
        (init_gnutls_functions): Load the two functions only if
        HAVE_GNUTLS_COMPRESSION_GET.
        (emacs_gnutls_certificate_export_pem): Use alloca instead of xmalloc.
        (Fgnutls_peer_status): Just return "NULL" if the functions
        are deprecated.
        (Fgnutls_format_certificate): Fix pointer signedness glitches.
        * src/process.c: Fix spacing.

        Put error output from M-! at the end of the error buffer

        * lisp/simple.el (shell-command-on-region): Put the error output

        This avoids interleaving error output.

        Restore functions for parsing subjects.
        (nsm-format-certificate): Use them to display more user-friendly

        Signal an error on `M-x shell-mode'

        * lisp/shell.el (shell-mode): This mode can't usefully be called
        interactively (and is somewhat destructive, as it disables
        `undo'), and it's usually confused with `shell-script-mode'
        (bug#19812).  So signal an error if it's used interactively.

2019-08-22  Lars Ingebrigtsen  <larsi@gnus.org>

        Make ibuffer-mark-by-file-name-regexp work on the displayed file name

        matching on the abbreviated (i.e., displayed) file name, and not
        the complete name (bug#18859).  This seems like the more expected
        action.

        Put index_size calculation closer to where it’s needed.
        (hash_clear): If hash_rehash_needed_p (h), don’t clear the

        Be more careful about pointers to bignum vals

        This uses ‘const’ to be better at catching bugs that

        Lisp bignums are supposed to be immutable.
        * src/alloc.c (make_pure_bignum):

        * src/bignum.h (bignum_val, xbignum_val): New inline functions.
        Prefer them to &i->value and XBIGNUM (i)->value, since they
        apply ‘const’ to the result.

        More-compatible subsecond calendrical timestamps

        Instead of appending a subseconds member to the result of
        ‘decode-time’, this keeps the format unchanged unless you give
        a new optional argument to ‘decode-time’.  Also, the augmented
        format now puts the subsecond info in the SECONDS element, so
        the total number of elements is unchanged; this is more
        compatible with code that expects the traditional 9 elements,
        such as ‘(pcase decoded-time (`(,SEC ,MIN ,HOUR ,DAY ,MON
        ,YEAR ,DOW ,DST ,ZONE) ...) ...)’.

        Fix rounding errors with float timestamps

        When converting from float to (TICKS . HZ) form, do the
        conversion exactly.  When converting from (TICKS . HZ) form to
        float, round to even precisely.  This way, successfully
        converting a float to (TICKS . HZ) and back yields a value
        numerically equal to the original.
        * src/timefns.c (flt_radix_power_size): New constant.
        (flt_radix_power): New static var.

        (decode_ticks_hz): It is now the caller’s responsibility to
        pass a valid TICKS and HZ.  All callers changed.
        Use frac_to_double to round (TICKS . HZ) precisely.
        (decode_time_components): When decoding nil, use
        decode_ticks_hz since it rounds precisely.
        (syms_of_timefns): Initialize flt_radix_power.

        Debug out-of-range make_fixnum args

        With --enable-checking, make_fixnum (N) now checks that N is
        in fixnum range.  Suggested by Pip Cet in:
        https://lists.gnu.org/r/emacs-devel/2019-07/msg00548.html
        A new function make_ufixnum (N) is for the rare cases where N
        is intended to be unsigned and is in the range 0..INTMASK.
        * configure.ac (AC_C_TYPEOF): Add.
        (HAVE_STATEMENT_EXPRESSIONS): Resurrect this macro.
        * src/fns.c (Frandom, hashfn_eq, hashfn_equal, hashfn_user_defined):
        * src/profiler.c (hashfn_profiler):
        Use make_ufixnum rather than make_fixum, since the argument is
        an unsigned integer in the range 0..INTMASK rather than a signed
        integer in the range MOST_NEGATIVE_FIXNUM..MOST_POSITIVE_FIXNUM.
        Typically this is for hashes.
        * src/lisp.h (lisp_h_make_fixnum_wrap) [USE_LSB_TAG]:
        Rename from lisp_h_make_fixnum.
        (lisp_h_make_fixnum): Redefine in terms of lisp_h_make_fixnum_wrap.
        Check for fixnum overflow on compilers like GCC that
        have statement expressions and typeof.
        (FIXNUM_OVERFLOW_P): Move up.
        (make_fixnum): Check for fixnum overflow.
        (make_ufixnum): New function, which checks that the arg

        Provide better target window consistency across x window property functions.

        Use the argument name WINDOW-ID instead of SOURCE for same.
        Revise docstrings to clarify semantics of FRAME and WINDOW-ID.

        (Fx_change_window_property): Use `target_window' instead of `w'.
        This is consistent with other related functions.
        Finalize its value before blocking input.

        (Fx_window_property):
        (Fx_window_property_attributes): Use `window_id' instead of `source'.

        (Fx_change_window_property): Rename SOURCE arg to WINDOW-ID

2019-08-08  Noah Friedman  <friedman@splode.com>

        (Fx_change_window_property): Add optional arg SOURCE.

        This provides symmetry with Fx_window_property, so that the window
        need not be an actual emacs frame.  This is useful for modifying
        properties of parent windows (specified with --parent-id to emacs) or
        generally assisting the window manager.

        When asking XTerm for the selection via OSC 52, use ST as string

        New function time-convert

        This replaces the awkward reuse of encode-time to both convert
        calendrical timestamps to Lisp timestamps, and to convert Lisp
        timestamps to other forms.  Now, encode-time does just the
        former and the new function does just the latter.

2019-07-31  Stefan Monnier  <monnier@iro.umontreal.ca>

        * src/lread.c (infile): Set/reset it like a dynamically scoped variable

        I've seen segfaults where `infile` is nil when we get to
        readbyte_from_file, presumably because Fload set it to NULL (via
        close_infile_unwind) just before returning to its caller which was
        probably itself within another read/load and for some reason
        readevalloop didn't get to re-set `infile` like it used to do at every
        iteration.  I was not able to really track down the bug, but the way
        `infile` was set/reset seemed fragile and managing it like a standard
        dynamically-scoped var seems both safer (and more efficient since we
        don't need readevalloop to constantly re-set it).

        (readchar): Assert that `infile` is set if using a function the depends on it.
        (readbyte_from_file): Assert that `infile` is set.
        (close_infile_unwind): Reset `infile` to its previous value rather than
        to NULL.
        (Fload): Remember the previous value of `infile` before chaning it.
        (readevalloop): Don't set `infile` any more.

        Revert "Make `ispell-change-dictionary' only list installed dictionaries"

        This reverts commit 848712b481e16f5c96fed6344c2f7d71a8d52ed1.

        There could be dictionaries available (set via command-line options for the
        speller, for instance) that would not be returned.

        the code, it doesn't seem like this function is actually used for
        doing that, either.  This makes describing some text properties

        This patch also moves the internal/external browser logic from
        shr to browse-url, where it belongs more naturally.

        * doc/misc/gnus.texi (Article Commands): Ditto.

        * lisp/gnus/gnus-art.el (gnus-button-url-regexp): Default to

        previously enjoyed by this variable.

        * lisp/progmodes/cc-cmds.el (c-forward-to-nth-EOF-{): Rename to
        c-forward-to-nth-EOF-\;-or-}, and when the starting (or ending) position is in
        the "variable" part of a struct/class/union/enum/etc., move to after the
        terminating semicolon.  Adjust the counting such that N only gets decremented
        on a successful movement over {..}.
        (c-beginning-of-defun, c-end-of-defun): Rename the calls to

        Have emacsbug only warn the user when sending to the bug address

        * lisp/mail/emacsbug.el (report-emacs-bug-hook): Only ask for
        confirmation if we're really sending the bug report to the bug
        address.  If the user is sending it somewhere else (to themselves,
        for instance), the warning is misleading.

2019-07-28  Lars Ingebrigtsen  <larsi@gnus.org>

        Allow the user to send a bug report after initially saying "no"

        * lisp/mail/emacsbug.el (report-emacs-bug-hook): Don't remove the
        address in the To: header (or the hook) after the user has said
        "no" (bug#23799).  This made it impossible for the user to do
        touch-ups and then resent the bug report.

        the backend (i.e., aspell/hunspell) provided a list of languages,
        don't add the base list (bug#24050).
        (ispell-set-spellchecker-params): Ditto.

        * lisp/emacs-lisp/bytecomp.el (byte-compile-out-toplevel): Fix bug#34757

        This fix was provided by Pip Cet <pipcet@gmail.com>.  It tightens the
        code that tries to recognize a bytecode sequence as being a simple
        function call (to then decompile it), which occasionally misfired.

        I added some minor changes found while investigating this issue.

        (byte-compile): Handle corner case where byte-compile-top-level returns
        a non-self-evaluating expression.
        (byte-compile-out-toplevel): Remove support for `progn` and `t` values
        of output-type which aren't used anywhere.

        (c-multichar->-op-not->>->>>-regexp) New lang const/var.

        * lisp/progmodes/cc-engine.el (c-forward-<>-arglist-recur): use the new

        Adjust location of Gnus group split setup process

        Updating group splits requires the gnus-newsrc-hashtb to be
        initialized. Previously this failed silently, now it errors.

        * lisp/gnus/gnus-mlspl.el (gnus-group-split-setup): Don't call the
        update when loading the user's init file, that's too early. Use
        appropriate hooks depending on AUTO-UPDATE.
        * doc/misc/gnus.texi (Group Mail Splitting): Change mention in docs.

        * lisp/nxml/nxml-mode.el (nxml-mode): Don't insert the XML
        declaration unless it's an empty buffer (bug#24978).  This avoids

        edebug-unknown and edebug-ok-coverage instead of unknown and
        ok-coverage to avoid naming collisions with packages that use
        those two symbols (bug#25471).

        we're recomputing it completely.
        (hash_table_rehash): Use hash_rehash_needed_p more.
        (hash_put): Add assertion that the slot was indeed considered empty.

        Improve pdumper doc; say unexec is deprecated

        Say that pdumping cannot redump unless -batch is used.  Say that
        the traditional unexec dumping method is by default not available,
        and is deprecated.  Don't call dump files "portable", as dump files
        are not any more portable than the Emacs executables themselves.
        Just call them "dump files".  Similar, prefer "portable dumper"
        (since the dumper code is portable) to "portable dumping" (since
        the dump file is not).  Be more systematic about calling them
        "dump files" instead of "dumped images" or whatnot.

        Improve doc for hash tables

        * doc/lispref/hash.texi (Creating Hash, Defining Hash):

        Say that hashes are fixnums.
        (Fmake_hash_table): Say that that an integer rehash-size
        should be a fixnum.
        * doc/lispref/hash.texi (Defining Hash): Say that hash and
        comparison functions should be consistent and pure, and should
        return quickly.

2019-07-21  Paul Eggert  <eggert@cs.ucla.edu>

        pure_alloc returns cleared memory

        * src/alloc.c (pure_alloc): Clear any heap-allocated storage.
        This is simpler than auditing all the callers to make sure
        they don’t assume pure memory is cleared memory, and the
        performance implication is nonexistent except when Emacs
        is misconfigured.  Also, add an assertion to catch
        caller misuse when pure space is exhausted.

        New static function.
        (Fexpand_file_name): If the current buffer's default-directory
        starts with "~user" where "user" is not a valid user name, don't
        give the '~' a special meaning.  Just treat the value of
        default-directory as a relative name.  (Bug#36502)
        * test/src/fileio-tests.el

2019-07-20  Paul Eggert  <eggert@cs.ucla.edu>

        Tweak recent hash-table fix

        * src/fns.c (maybe_resize_hash_table): Completely initialize the
        new ‘next’ vector before allocating more vectors, as this
        preserves locality a bit better and it’s safer not to leave an
        uninitialized Lisp object around.  Use next_size instead of
        new_size to compute new index size.

2019-07-20  Paul Eggert  <eggert@cs.ucla.edu>

        Fix crash if user test munges hash table

        * src/fns.c (restore_mutability)
        (hash_table_user_defined_call): New functions.
        (cmpfn_user_defined, hashfn_user_defined): Use them.
        (make_hash_table, copy_hash_table):
        Mark new hash table as mutable.
        (check_mutable_hash_table): New function.
        (Fclrhash, Fputhash, Fremhash): Use it instead of CHECK_IMPURE.
        * src/lisp.h (struct hash_table_test): User-defined functions
        now take pointers to struct Lisp_Hash_Table, not to struct
        hash_table_test.  All uses changed.
        (struct Lisp_Hash_Table): New member ‘mutable’.
        * src/pdumper.c (dump_hash_table): Copy it.
        * test/src/fns-tests.el (test-hash-function-that-mutates-hash-table):
        New test, which tests for the bug.

2019-07-20  Paul Eggert  <eggert@cs.ucla.edu>

        Simplify hashfn/cmpfn calling convention

        * src/fns.c (cmpfn_eql, cmpfn_equal, cmpfn_user_defined)
        (hashfn_eq, hashfn_equal, hashfn_eql, hashfn_user_defined):
        * src/profiler.c (cmpfn_profiler, hashfn_profiler):
        Use new calling convention where the return value is a fixnum
        instead of EMACS_UINT.  While we’re at it, put the hash table
        at the end, since that’s a bit simpler and generates better
        code (at least on the x86-64).  All callers changed.
        * src/fns.c (hash_lookup): Store fixnum rather than EMACS_UINT.
        All callers changed.
        (hash_put): Take a fixnum rather than an EMACS_UINT.
        All callers changed.  Remove unnecessary eassert (XUFIXNUM does it).
        * src/lisp.h (struct hash_table_test):
        Adjust signatures of cmpfn and hashfn.

2019-07-20  Paul Eggert  <eggert@cs.ucla.edu>

        Inhibit GC after inhibit_garbage_collection

        Without this patch, there are unlikely ways that garbage
        collection could occur (sometimes causing undefined behavior)
        even when inhibit_garbage_collection is in effect.
        * src/alloc.c (garbage_collection_inhibited): New var.
        (pure_alloc): Increment it if pure space is exhausted, so that
        garbage_collect_1 no longer needs to inspect
        pure_bytes_used_before_overflow.
        (allow_garbage_collection): New function.
        (inhibit_garbage_collection): Increment the new variable rather
        than specbinding a user variable.
        (garbage_collect_1): Do not garbage collect if the new variable
        is set, rather than if pure_bytes_used_before_overflow is set.

2019-07-20  Paul Eggert  <eggert@cs.ucla.edu>

        Simplify maybe_gc implementation

        * src/alloc.c (consing_until_gc): New variable, replacing the
        combination of consing_since_gc and gc_relative_threshold.
        All uses changed.
        (byte_ct): Move decl here from lisp.h.
        (memory_full_cons_threshold): New an enum constant.
        (free_cons): Check for integer overflow in
        statistics calculation.
        * src/lisp.h (object_ct): Move decl here from alloc.c.
        (OBJECT_CT_MAX): New macro.
        (maybe_gc): Simplify accordingly.

2019-07-20  Paul Eggert  <eggert@cs.ucla.edu>

        Rename ‘pure’ to ‘purecopy’

        * src/lisp.h (struct Lisp_Hash_Table): Rename ‘pure’ member to
        ‘purecopy’, as the old name was quite confusing (it did not
        mean the hash table was pure).  All uses changed.

2019-07-20  Paul Eggert  <eggert@cs.ucla.edu>

        Fix hash table overallocation etc.

        * src/fns.c (set_hash_key_and_value, set_hash_next)
        (set_hash_hash, set_hash_index): Remove.  All uses removed.
        (maybe_resize_hash_table): Don’t update h->next until it’s
        known that all the allocations succeeded, to avoid trashing
        the hash table if memory is exhausted.  Don’t overallocate the
        other vectors.  Don’t output growth message if the hash table
        didn’t actually grow due to allocation failure.  Assume C99
        decls after statements.

        Do not alter match data in Fcapitalize etc.

        Without this patch, (capitalize "x") can alter the match data,
        which is not what users expect.  Problem found by running

2019-07-07  Paul Eggert  <eggert@cs.ucla.edu>

        Remove printmax_t etc.

        IDs in the minibuffer.  Improves on previous brittle approach of
        word-at-point -> read-string -> string-to-number by a) defaulting to

        without using the intrusive INITIAL-INPUT argument, and b) not
        attempting to parse bug IDs.
        (gnus-read-ephemeral-bug-group): Use it.  Extend docstring and
        commentary.  Fix handling of multiple bug IDs as either numbers or
        strings.  Hoist some string consing out of inner loop.  Delete
        temporary file even on error.  Throw more informative error when
        url-insert-file-contents successfully returns an error (bug#36433).
        (gnus-read-ephemeral-debian-bug-group): Use gnus-group--read-bug-ids
        and fix docstring for multiple bug IDs.  Accept optional WINDOW-CONF
        like other ephemeral bug group commands.
        (gnus-read-ephemeral-emacs-bug-group): Use gnus-group--read-bug-ids
        and fix string/numeric ID conversions.  Try loading debbugs-gnu
        before testing for debbugs-gnu-summary-mode (bug#36433).

        Fix Flymake's user-visible accessors of diagnostic positions

        Diagnostics are supported by overlays, and they can legitimately move
        around.  So flymake-diagnostic-beg and flymake-diagnostic-end must
        look up the overlay positions, not the immutable slots of the
        flymake--diag structure, which become stale.

        * lisp/progmodes/flymake.el (version): Bump to 1.0.8.
        (flymake-diagnostic-beg, flymake-diagnostic-end): Use diag's
        overlay.

        flymake-diagnostic-beg.

        Small fix to writing Gnus dribble change-level entries

        * lisp/gnus/gnus-start.el (gnus-group-change-level): PREVIOUS needs to
          still be a string when the dribble entry is written, so don't
          convert it to an entry until after that's done. Also, we're not
          meant to write PREVIOUS itself, we're meant to write the group that
          comes _after_ it in the sort-order of gnus-group-list, so do that
          instead.

        Protect Flymake from being corrupted by backends

        A backend building a diagnostic with a nil :type would cause Flymake
        to create a diagnostic without an overlay, confusing Flymake's
        accounting of overlays and diagnostics

        * lisp/progmodes/flymake.el (flymake--highlight-line): Return
        non-nil unconditionally.

2019-07-02  João Távora  <joaotavora@gmail.com>

        More carefully cleanup Flymake C/C++ backend's temp buffers

        Sometimes the Flymake process dies by some means that doesn't involve
        a sentinel call for the "exit" status, so we clean up the temporary
        buffer as soon as we notice it's not process-alive-p anymore.

        conditions.

        Support native image transforms on MS-Windows

        This changeset also rearranges native image transform code
        for other platforms to make it cleaner, and also removes
        the support for native cropping.  For the discussions, see
        https://lists.gnu.org/r/emacs-devel/2019-06/msg00242.html

        * src/w32term.c (w32_image_rotations_p, transform): New functions.
        (w32_draw_image_foreground): If image rotation is requested
        and supported, call PlgBlt to transform the image.
        (w32_initialize): Populate the PlgBlt function pointer if it
        is supported.
        * src/w32term.h (w32_image_rotations_p): Add prototype.

        * src/image.c (compute_image_rotation): Renamed from
        image_set_rotation.  Only compute and returns the rotation
        angle; leave the matrix calculation for later.  Log an error
        message if the :rotation parameter is not a number.
        (image_set_crop): Function deleted.  We no longer support
        native cropping, as one can display an image slice instead.
        (image_set_transform): Compute the transform matrix in its
        entirety here, in two variants: one for XRender and Cairo, the
        other for NS and MS-Windows.  call compute_image_size and
        compute_image_rotation internally.
        (lookup_image) [HAVE_NATIVE_TRANSFORMS]: Call only
        image_set_transform.  No need to pass the transform matrix to
        image_set_transform.
        (Fimage_transforms_p): Return a list of transform capabilities
        rather than a simple boolean.  Support TTY frames as well.
        * src/nsimage.m (setTransform:): Don't invert the matrix, as
        it is already inverted in image.c.

        * test/manual/image-transforms-tests.el (test-cropping): State
        in the text that only ImageMagick supports cropping.

        * doc/lispref/display.texi (Image Descriptors): Update the
        documentation of native image transforms.
        (ImageMagick Images): Move the description of ':crop' here.

        Improve ‘equal’ and array doc

        * doc/lispref/objects.texi (Array Type): Array sizes are
        nonnegative fixnums, not arbitrary integers.
        (Equality Predicates): Do not say that ‘eq’ equals ‘=’ on bignums.
        Do not imply that ‘equal’ must signal an error on circular lists.

2019-06-27  Paul Eggert  <eggert@cs.ucla.edu>

        Omit a few minor unnecessary range checks

        Based on Pip Cet’s review (Bug#36370#19).
        * src/fileio.c (Fdo_auto_save):
        * src/image.c (lookup_image):
        * src/textprop.c (Fnext_single_char_property_change):
        Prefer XFIXNUM to XFIXNAT for clarity and consistency with
        neighboring code, and to avoid unnecessary range checks.
        * src/image.c (lookup_image): Omit unnecessary range checks.

2019-06-27  Paul Eggert  <eggert@cs.ucla.edu>

        Improve XFIXNUM cleanup a bit

        Based on Pip Cet’s review (Bug#36370#13).
        * src/ccl.c (Fccl_execute_on_string): Use clearer indexing.
        * src/dosfns.c (Fint86, Fdos_memput):
        Avoid runtime checks for negative fixnums when debugging.
        This restores the earlier machine code.
        * src/lisp.h (XFIXNUM, XUFIXNUM): Use eassert, not eassume.
        (XFIXNAT): At the start, merely eassert FIXNUMP rather
        than eassuming FIXNATP.  At the end, eassume that the
        result is nonnegative.  This restores help to the compiler
        that the previous patch mistakenly removed.

2019-06-27  Paul Eggert  <eggert@cs.ucla.edu>

        Clean up use of XFIXNUM etc.

        A few bits of the code were relying on the fact that XFIXNUM,
        XFIXNAT, and XUFIXNUM do something even with arguments that
        are not fixnums/fixnats.  Separate these rare uses out into
        XFIXNUM_RAW and XUFIXNUM_RAW.
        Problem and original patch reported by Pip Cet (Bug#36370).
        * src/ccl.c (Fccl_execute_on_string):
        * src/fileio.c (Finsert_file_contents, a_write)
        (Fdo_auto_save):
        * src/process.c (conv_lisp_to_sockaddr):

        (Fprevious_single_char_property_change)
        (Fnext_property_change, Fnext_single_property_change)
        (Fprevious_property_change)
        (Fprevious_single_property_change):
        Don’t assume fixnums are nonnegative.
        * src/ccl.c (Fccl_execute_on_string):
        Fix range-checking bug if AREF (status, i) is out of int range.
        * src/data.c (arith_driver): Use XFIXNUM_RAW as we want
        efficient garbage if the value is not a fixnum.
        * src/dosfns.c (Fint86, Fdos_memput):
        Check that args are nonnegative.
        * src/image.c (lookup_image): Check that args are in range.
        * src/lisp.h (lisp_h_XHASH): Use XUFIXNUM_RAW, since this
        is for hashing.
        (lisp_h_XFIXNAT, XFIXNAT) [USE_LSB_TAG]: Remove macros.
        (lisp_h_XFIXNUM_RAW, XFIXNUM_RAW) [USE_LSB_TAG]: New macros, with
        the semantics of the old macros without _RAW.
        (XFIXNUM_RAW, XUFIXNUM_RAW): New inline functions, with the
        semantics of the old functions without _RAW.
        (FIXNUMP): Move definition up to avoid forward use.
        (XFIXNUM, XFIXNAT, XUFIXNUM): Use eassume to add a runtime
        check (when debugging) that the argument has the proper form.
        (XFIXNUM, XFIXNAT): Now inline functions only, since they
        refer to their arguments more than once now that they use eassume.
        * src/textprop.c (Fprevious_single_char_property_change):
        Avoid fixnum overflow with invalid input.
        (set_text_properties): Fix unlikely failure
        to validate arguments, by using EQ instead of XFIXNAT.
        * src/w32term.c (w32_draw_glyph_string):
        * src/xterm.c (x_draw_glyph_string):
        Treat negative minimums as 0 rather than as garbage patterns.

2019-06-27  Paul Eggert  <eggert@cs.ucla.edu>

        Catch duplicate keywords in image specs

        * src/image.c (struct image_keyword.count): Now bool, not int,
        since it is either 0 or 1.
        (parse_image_spec, xpm_image_p): Use bool for boolean.
        (parse_image_spec): Fix a bug introduced in
        2011-09-21T17:41:20!eggert@cs.ucla.edu that reported only
        triplicate (or more) keywords, not duplicates.

        Mention the new emacsclient -a/--eval behaviour

2019-06-27  Lars Ingebrigtsen  <larsi@gnus.org>

        emacsclient: ignore --eval parameters when starting alternate editor

        * lib-src/emacsclient.c (fail): If the user said --eval, don't
        pass those arguments to the alternate editor as file names.
        Suggested by a patch from Scott Turner (bug#11474).

        This reverts commit 573de396f03684efa89ead24a371b0f4c9bf8d5d.

        `replace-regexp-in-string' omits the first START characters of the

        Fix previous patch to dired-mark-if

        * lisp/dired.el (dired-mark-if): Don't use looking-at to check for

2019-06-25  Paul Eggert  <eggert@cs.ucla.edu>

        Prefer PATH_MAX to MAXPATHLEN

        PATH_MAX is standardized, MAXPATHLEN is not.
        Also, the Gnulib pathmax module fixes some rare bugs with PATH_MAX.
        So prefer PATH_MAX to MAXPATHLEN unless we know the latter is
        also correct (for some platform-specific code).
        * admin/merge-gnulib (GNULIB_MODULES): Add pathmax.
        This module was already present, as a dependency of canonicalize-lgpl,
        but now Emacs is using it directly.  Sort.
        * lib-src/emacsclient.c: Include stdint.h, pathmax.h.
        (get_current_dir_name): Sync to current src/sysdep.c.
        * lib/gnulib.mk.in, m4/gnulib-comp.m4: Regenerate.
        * src/sysdep.c: Include pathmax.h.
        (get_current_dir_name_or_unreachable):
        Use PATH_MAX instead of MAXPATHLEN.

        * lisp/view.el (view-search): Jump to the next/prev occurrence of

        This seems more logical than the previous (undocumented) behaviour.

        * lib-src/etags.c (Prolog_functions, prolog_pr)
        (Erlang_functions, erlang_func):
        Prefer ptrdiff_t to size_t when either will do.
        (prolog_pr, erlang_func): New arg LASTLEN, to avoid
        unnecessary strlen call. All callers changed.
        * lib/gnulib.mk.in, m4/gnulib-comp.m4: Regenerate.
        * lib/strnlen.c, m4/strnlen.m4: New files, copied from Gnulib.

        This fixes bug #25111.

        * doc/lispref/display.texi (Overlay Properties): For the hook property
        modification-hooks, state that inhibit-modification-hooks is bound to non-nil
        when calling its functions.  This also applies to insert-in-front-hooks and

        modification-hooks, state that inhibit-modification-hooks is NOT bound to

2019-06-24  Lars Ingebrigtsen  <larsi@gnus.org>

        Make message_to_stderr do one single fwrite

        * src/xdisp.c (message_to_stderr): When running as a batch
        process, the output from `message' goes to stderr, and has a
        newline appended.  Rewrite the code so that only one fwrite is
        performed to enable messages that are shorter than PIPE_BUF
        (usually 4096 on modern operating systems) are written out as one
        chunk, as this will ensure that the messages are not interleaved
        with messages from other processes that are writing at the same
        time.  This does not affect other stderr outputs, just the ones
        from `message'.

        Minimize entry parsing in auth-source-pass

        Prior to this commit, while searching for the most applicable entry
        password-store entries were decrypted and parsed to ensure they were
        valid.  The entries were parsed in the order they were found on the
        filesystem and all applicable entries would be decrypted and parsed,
        which varied based on the contents of the password-store and the entry
        to be found.

        This is fine when the GPG key is cached and each entry can be
        decrypted without user interaction.  However, for security some people
        have their GPG on a hardware token like a Yubikey setup so that they
        have to touch a sensor on the toke for every cryptographic operation,
        in which case it becomes inconvenient as each attempt to find an entry
        requires a variable number of touches of the hardware token.

        The implementation already assumes that names which contain more of
        the information in the search key should be preferred so there is an
        ordering of preference of applicable entries.  If the decrypt and
        parsing is removed from the initial identification of applicable
        entries in the store then in most cases a single decrypt and parse of
        the most preferred entry will suffice, improving the experience for
        hardware token users that require interaction with the token.

        This commit implements that strategy.  It is in spirit a refactor of
        the existing code.

        * lisp/auth-source-pass.el (auth-source-pass--matching-entries): New
        function, generate an ordered list of regular expression matchers for
        all possible names that could be in the password-store for the entry
        to be found and then makes a pass over the password-store entry names
        accumulating the matching entries in a list after the regexp that
        matched.  This implementation ensures the password-store entry list
        still only has to be scanned once.
        (auth-source-pass--find-match-unambiguous): Use it to obtain candidate
        entries and then parse them one by one until an entry containing the
        desired information is located.  When complete, return the parsed data
        of the entry instead of the entry name so that the information can be
        used directly to construct the auth-source response.
        (auth-source-pass--build-result): Update accordingly.
        (auth-source-pass--find-match): Update docstring accordingly.
        (auth-source-pass--select-one-entry)
        (auth-source-pass--entry-valid-p)
        (auth-source-pass--find-all-by-entry-name)
        (auth-source-pass--find-one-by-entry-name): Remove.
        (auth-source-pass--select-from-entries)
        (auth-source-pass--accumulate-matches)
        (auth-source-pass--entry-reducer)
        (auth-source-pass--generate-entry-suffixes)
        (auth-source-pass--domains)
        (auth-source-pass--name-port-user-suffixes): New functions.

        * test/lisp/auth-source-pass-tests.el: One test case was added to the
        test suite to verify that only the minimal number of entries are
        parsed in common cases.  The
        auth-source-pass-only-return-entries-that-can-be-open test case had to
        be re-implemented because the function it was used eliminated as the
        functionality is provided elsewhere.  All the other fairly substantial
        changes to the test suite are the result of mechanical changes that
        were required to adapt to auth-source-pass--find-match returning the
        data from a parsed password-store entry instead of the entry name.

2019-06-24  Keith Amidon  <camalot@picnicpark.org>

        Split out the attribute retrieval form auth-source-pass-get

        Eliminate the need to repeatedly retrieve and parse the data for the
        entry.  This is generally a good thing since it eliminates repetitions
        of the same crypto and parsing operations.  It is especially valuable
        when protecting an entry with a yubikey with touch required for crypto
        operations as it eliminates the need to touch the yubikey sensor for
        each attribute retrieved.

        * lisp/auth-source-pass.el (auth-source-pass-get): Extract some code to
        `auth-source-pass--get-attr'.
        (auth-source-pass--get-attr): New function to get a field value from a
        parsed entry.
        (auth-source-pass--build-result): Make use of
        `auth-source-pass--get-attr` to avoid repeated parsing.

        Fix auth-source-pass to search for hostname:port/username

        auth-source-pass supports entries with username either prefixed to the
        hostname with an @ as separator or in a subdirectory under the
        hostname.  This was true when there was no port or service included in
        the name, but got broken with the introduction of
        auth-source-pass-port-separator.

        * lisp/auth-source-pass.el (auth-source-pass--find-match-unambiguous): Fix
        to match hostname:port/username.
        * test/lisp/auth-source-pass-tests.el: Add corresponding tests.

        (auth-source-pass--find-match-unambiguous): Adapt to make use of the
        new variable.

        `~/.password-store'.

        Optional space and unit in `file-size-human-readable' (bug#35756)

        To improve readability of strings produced by
        `file-size-human-readable', add two optional arguments:

        - SPACE, to provide a string (typically a space or non-breaking space)
        to put between the number and unit.  For compatibility, the default is
        an empty string.

        - UNIT, a string to use as unit.  For compatibility, the default is
        "B" in `iec' mode and the empty string otherwise.

        Also fix a glitch with small numbers in `iec' mode which caused a
        stray "i" in the result.

        Compile any subsequence of `cond' clauses to switch (bug#36139)

        A single `cond' form can how be compiled to any number of switch ops,
        optionally interspersed with non-switch conditions.
        Previously, switch ops would only be used for whole `cond' forms
        containing no other tests.

        * lisp/emacs-lisp/bytecomp.el (byte-compile--cond-vars):
        Rename from `byte-compile-cond-vars'.
        (byte-compile--default-val): Remove.

        Use the most specific of `memq', `memql' and `member' in or-patterns
        with constant cases.  This improves performance and may help the byte-code
        compiler generate a switch.

        * lisp/emacs-lisp/disass.el (disassemble-1): Remove a

2019-06-12  Lars Ingebrigtsen  <larsi@gnus.org>

        Revert previous ps-mode.el change

        * lisp/progmodes/ps-mode.el (ps-mode-octal-region): Revert
        previous change because the `string-make-unibyte' insertion was
        the previous single change (in 2013) to this file, so it must have
        some subtle meaning or other.

2019-06-12  Lars Ingebrigtsen  <larsi@gnus.org>

        semi-deprecated functions rely on each other.

        Tune base64 decoding

        This improves performance of base64-decode-region by about 7.5% on
        my platform, and gets rid of some macros.
        * src/fns.c (IS_ASCII, IS_BASE64, IS_BASE64_IGNORABLE)
        (READ_QUADRUPLET_BYTE): Remove.
        (base64_value_to_char, base64_char_to_value):
        Now an array of two arrays.  All uses changed.
        (base64url_value_to_char, base64url_char_to_value):
        Remove.  All uses changed to the other array.
        (base64_char_to_value): Entries are now of type signed char, not
        short, since we can assume C99.  Use C99 initializers; this is
        clearer and caters to the (theoretical) possibility of systems
        that do not use ASCII or do not have 8-bit bytes.  Allow any index
        in the range 0..UCHAR_MAX instead of limiting it to 0..127, so
        that uses need not check for in-range indexes.  Also record
        padding chars.  All uses changed.
        (base64_decode_1): Always store number of chars in *NCHARS_RETURN,
        for simplicity.  All callers changed.  Speed up the byte-fetching.

        The copy_file_range syscall (introduced in Linux kernel

        * admin/merge-gnulib (GNULIB_MODULES): Add copy-file-range.

        double-to-int conversion and to reduce bignum rotations correctly.
        (image_set_crop): Finish up previous correction, by not re-setting
        width and height if compute_image_size has set them.

        Since the hostname returned by irc.freenode.net can be something other
        than irc.freenode.net, e.g. niven.freenode.net, the entries for
        rcirc-authinfo and rcirc-server-alist will not match.

        returned), this corresponds with what rcirc-authenticate does.
        Moreover, if rcirc-auto-authenticate-flag is set, check the
        corresponding rcirc-authinfo, regardless of whether the

        Instead of using after-change-functions.  Also, stop consulting
        nxml-prolog-regions during syntax-propertize.  It turns out the
        problems fixed by using prolog information are actually due to using
        the wrong syntax table during propertizing.  This was fixed in
        2019-06-04 "* lisp/emacs-lisp/syntax.el: Use syntax-ppss-table for

        macros for matrix manipulation.
        (HAVE_NATIVE_SCALING, HAVE_NATIVE_TRANSFORMS): Rename and change all

        Do not use syntax-ppss-table in syntax-propertize when nil (Bug#36095)

        * lisp/emacs-lisp/syntax.el (syntax-propertize): Use (syntax-table)
        instead of syntax-ppss-table when the latter is nil.

2019-06-04  Stefan Monnier  <monnier@iro.umontreal.ca>

        * lisp/emacs-lisp/syntax.el: Use syntax-ppss-table for syntax-propertize.

        `syntax-ppss` uses `syntax-ppss-table` while parsing the buffer as well
        as when it calls `syntax-propertize`, but `syntax-propertize` can also
        be called directly rather than via `syntax-ppss` so it needs to explicitly
        use `syntax-ppss-table` as well in order to avoid using sometimes one
        table and sometimes another.

        (syntax-ppss-table): Move before new use.
        (syntax-propertize): Use it.

        Revert "Add extra text property to fix issue with js2-mode integration"

        This reverts commit 382a508ed21e4f12ace9f8871818e25235e8f05e.

        We ended up deciding against using this in js2-mode.  Instead,
        js2-mode may eventually use js-mode’s syntax-propertize-function to
        set syntax-table text properties.

        * lisp/international/mule-cmds.el (encode-coding-char): Fix ASCII case

        Don't bother with string-as-multibyte since `string` already returns
        multibyte when needed.  Don't forget to encode when the string is
        ASCII, e.g. for ebcdic case and to make sure we always return
        a unibyte string.

        is a 'char **', not a 'char *'.  This fixes -xrm handling on
        MS-Windows, broken by conversion of x_get_string_resource to
        terminal-specific hook.

        Correctly eliminate duplicate cases in switch compilation

        Fix code mistakes that prevented the correct elimination of duplicated
        cases when compiling a `cond' form to a switch bytecode, as in

          (cond ((eq x 'a) 1)
                ((eq x 'b) 2)
                ((eq x 'a) 3)   ; should be elided
                ((eq x 'c) 4))

        Sometimes, this caused the bytecode to use the wrong branch (bug#35770).

        * lisp/emacs-lisp/bytecomp.el (byte-compile-cond-vars): Return obj2 eval'ed.
        (byte-compile-cond-jump-table-info):
        Discard redundant condition.  Use `obj2' as evaluated.
        Discard duplicated cases instead of failing the table generation.
        * test/lisp/emacs-lisp/bytecomp-tests.el (toplevel): Require subr-x.
        (byte-opt-testsuite-arith-data, bytecomp-test--switch-duplicates): Test.

        * lisp/emacs-lisp/rmc.el (read-multiple-choice): Use `read-event'

2019-05-26  Paul Eggert  <eggert@cs.ucla.edu>

        Update author/maintainer info

        Update email addresses and fix spellings of some author and
        maintainer names.

2019-05-26  Paul Eggert  <eggert@cs.ucla.edu>

        Remove Maintainer: when it duplicates Author:

        The convention is that a file with Author: but not Maintainer:
        means the author is a maintainer, which makes it confusing
        when a file lists the same person as author and maintainer.
        Avoid the confusion by removing the duplicate Maintainer: line.

        Document ‘Maintainer: emacs-devel@gnu.org’

        * doc/lispref/tips.texi (Library Headers): Document that the
        Maintainer: line now says ‘emacs-devel@gnu.org’ rather than ‘FSF’.

2019-05-25  Paul Eggert  <eggert@cs.ucla.edu>

        Go back to "Maintainer: emacs-devel@gnu.org"

        Restore lines saying "Maintainer: emacs-devel@gnu.org" when there is
        no special maintainer for a file.  Although this wasn't documented
        it was common practice and removing the lines didn't have consensus.

        Remove fixnum restriction on some display vars

        This is a minor patch to remove some fixnum restrictions.
        Many more such patches are needed, but one thing at a time.
        * doc/emacs/custom.texi (Examining): Update fill-column example.
        * src/buffer.c (fill-column, left-margin, tab-width)
        (buffer-saved-size, left-margin-width, right-margin-width)
        (left-fringe-width, right-fringe-width, scroll-bar-width)
        (scroll-bar-height, buffer-display-count):
        Allow any integer; do not restrict to fixnums.
        * src/character.h (SANE_TAB_WIDTH): Do not assume tab_width
        is a nonnegative fixnum.
        (sanitize_tab_width): Take a Lisp_Object integer, not an
        EMACS_INT.  Only use changed.
        * src/data.c (store_symval_forwarding): Remove unnecessary
        SYMBOLP since the predicate (e.g., Qintegerp) is always a
        symbol (leave the test in as an eassert).  Avoid assignments
        inside if-conditions.
        * src/fileio.c (Fdo_auto_save): Do not assume
        buffer-saved-size is a fixnum.  Avoid undefined behavior
        on EMACS_INT overflow by multiplying a fixnum by at most 4,
        not by at most 13.
        * src/window.c (set_window_buffer): When buffer-display-count
        is too large for a fixnum, make it a bignum.
        * src/xdisp.c (FILL_COLUMN_INDICATOR_NEEDED): Remove macro, ...
        (fill_column_indicator_column): ... replacing with this new function.
        All uses changed.  The function is a bit pickier, to prevent
        problems with non-character fixnums and columns out of range
        for int, and to remove the assumption that integers are in
        fixnum range.
        (append_space_for_newline, extend_face_to_end_of_line):
        Avoid undefined behavior with signed integer overflow.
        Simplify.

        Avoid polling in global-auto-revert-mode (bug#35418)

        Make `auto-revert-avoid-polling' have effect in global-auto-revert-mode.
        Buffers actually handled by that mode are marked with a non-nil value
        of `auto-revert--global-mode'.  When global-auto-revert-mode is
        entered, eligible buffers are marked in that way, and hooks are set up
        to mark new buffers and take care of buffers whose file names change.
        This way the existing poll-avoidance logic can be used, since the
        entire set of buffers in auto-revert is known.

        A new hook, `after-set-visited-file-name-hook', was added to handle
        the case when the file name of a tracked buffer changes.

        * lisp/autorevert.el (auto-revert-avoid-polling): Amend doc string.
        (auto-revert--global-mode): New buffer-local variable.
        (global-auto-revert-mode): Mark existing buffers and set up hooks when
        mode is entered; do the opposite when exited.

        * lisp/emacs-lisp/package.el: Fix decoding of downloaded files

        This is a different fix for bug#34909, which should also fix bug#35739.

        Our downloading code used to automatically decode the result according
        to the usual heuristics for files.  This caused problems when we later
        needed to save the data in a file that needed to be byte-for-byte
        equal to the original in order to pass the signature verification,
        especially because we didn't keep track of which coding-system was
        used to decode the data.

        (package--unless-error): New macro extracted from
        package--with-response-buffer-1, so that we can specify edebug and
        indent specs.
        (package--with-response-buffer-1): Use it.  More importantly, change
        code so it runs `body` in a unibyte buffer with undecoded data.
        (package--download-one-archive): Don't encode with utf-8 since the data
        is not decoded yet.
        (describe-package-1): Explicitly decode the readem.txt files here.

        * lisp/url/url-handlers.el (url-insert-file-contents): Use it.
        (url-insert): Don't decode if buffer is unibyte.

        * lisp/url/url-http.el (url-http--insert-file-helper): New function,
        extracted from url-insert-file-contents.

        For SVG, 8192 is the new 256

        Prefer librsvg for display of splash.svg
        When both librsvg and Imagemagick are available, Emacs should
        prefer librsvg to render SVG images.  However, Emacs was using
        Imagemagick to render its own splash.svg file because
        image-type-from-file-header returned nil for that file.
        * lisp/image.el (image-type-from-buffer)
        (image-type-from-file-header): Look at the first 8192 bytes of
        the image, not just the first 256.  For Emacs’s own splash.svg
        file, image-type-header-regexps needs to look at 939 bytes.
        8192 bytes is a reasonable number nowadays given typical file
        system design.
        * test/lisp/image-tests.el (image-tests--emacs-images-directory):

        Allow non-file buffers to declare that notification on their

        * lisp/gnus/nnheader.el (mail-header-*): Define via cl-defstruct

        This also has the side effect that the accessors are now defined as proper
        functions rather than as macros, so they can be passed to `mapcar` etc..

        * lisp/emacs-lisp/cl-macs.el (cl--sm-macroexpand) <setq>: Rewrite

        The previous code had 2 problems:
        - It converted `setq` to `setf` in unrelated cases such as
          (cl-symbol-macrolet ((x 1)) (setq (car foo) bar))
        - It macroexpanded places before `setf` had a chance to see if they
          have a gv-expander.

        lost in the conflict against 2019-05-09 "Recognize single quote
        attribute values in nxml and sgml (Bug#35381)".
        * lisp/textmodes/sgml-mode.el (sgml-syntax-propertize-rules): Reapply
        the 2019-01-17 change to speed up sgml-syntax-propertize-rules, taking
        into account the 2019-05-09 which means we have to handle single
        quotes as well.

        Replace backquoted lambda with closure.
        (gnus-summary-article-header): Use define-inline rather than defmacro,
        so it's also a function.
        (gnus-save-hidden-threads, gnus-summary-iterate, gnus-with-article):
        Use `declare`.

        Tune reading of radix integers

        This improves the performance of (read "%xFF") by about 25%
        on my platform.

        buffer sizes of arguments.

        Add standard unmatchable regexp

        Add `regexp-unmatchable' as a standard unmatchable regexp, defined as

        * lisp/net/tramp.el (tramp-interrupt-process): Remove with-timeout.
        Instead pass a timeout to tramp-accept-process-output.

        ImageMagick has continuing stability and security problems, suggesting

        * lisp/help.el (help--read-key-sequence): Handle `switch-frame' events

        If you do `C-h k ... mouse-1 in other frame` (at least if you have a focus
        that follows the mouse), then additionally to the down-mouse-1 and mouse-1
        events, a `switch-frame` event (and `select-window` event as well sometimes)
        is generated.  When `read-key-sequence` is called with nil for
        `can-return-switch-frame`, this event is not returned but kept for later,
        which causes a subsequent `sit-for` to return nil immediately.
        This interfered without our "wait for double-click" which in turn prevented
        us from stopping after the mouse-1 click, getting stuck waiting for something
        else instead.

        (help--read-key-sequence): Pass a non-nil `can-return-switch-frame`, so the
        subsequent `sit-for` returns more trustworthy information.

        Fix setting and resetting of scroll-with-delete

        The start and end lines of the scroll region must to be in the range
        [0,term-height).  There are few placees that incorrectly set the end
        line of the scroll region to term-height which is outside the valid
        range.  Combined with another off-by-one error in
        term-set-scroll-region's clamping logic, this would cause
        term-scroll-with-delete to be unnecessarily turned on.

        * lisp/term.el (term-scroll-start,term-scroll-end): Use defvar-local

        * src/marker.c (buf_bytepos_to_charpos): Re-add the CHAR_HEAD_P assertion

        This assertion was removed in 1c349c62305d432abf0fa2b6e3f5d754fe4cab79
        because the assumption was invalid during set_intervals_multibyte_1.
        So we change set_intervals_multibyte_1 to solve the problem in the same
        way as in the rest of Fset_buffer_multibyte, which actually simplifies
        the code.

        * src/buffer.c (advance_to_char_boundary): Not static any more.
        * src/buffer.h (advance_to_char_boundary): Add prototype.

        Use simpler way to print function pointers

        The module code can’t possibly work on weird platforms where
        function pointers are wider than data pointers, so there’s no need
        to bother with the stackoverflow-like approach that is intended
        only for portability to such platforms.  Besides, the
        stackoverflow-like approach does not work well on weird platforms
        where CHAR_BIT is not a multiple of 4.

        Refactoring: Factor out a function to set an mpz_t from a Lisp int.

        * src/bignum.h (mpz_set_integer): New function.

        * src/emacs-module.c (module_make_big_integer): Use it.

        Avoid undefined behavior when printing function pointers.

        * src/print.c (print_vectorlike): Don’t pass a function pointer to
        ‘snprintf’, as that is undefined behavior.  Instead, print the
        individual bytes making up the function pointer.

        Notify broken file notification from Tramp

        Set process sentinel.

        Port new fingerprinting scheme to clang + LTO

        * lib-src/make-fingerprint.c (main): Don't consider multiple
        instances of the fingerprint to be an error, as this can
        happen with clang and -flto.  Instead, replace all instances
        of the fingerprint.  There is a tiny chance that this will
        silently corrupt the Emacs executable.

        This patch suggests that we should go back to fingerprinting
        the inputs to the linker instead of its output, as the new
        fingerprinting scheme is unnecessarily complicated and this
        complexity reduces reliability. The old scheme (i.e., before
        commit 2019-05-14T23:31:24Z!eggert@cs.ucla.edu) was simpler
        and more portable and good enough, and it's looking like it
        would be less trouble in practice than the new scheme.

        `ansi-color-apply-face-function' while calling
        `ansi-color-apply-on-region'.  Use `font-lock-face' to propertize
        instead of `face'.

2019-05-04  Eli Zaretskii  <eliz@gnu.org>

        Minor fix in .gdbinit

        * src/.gdbinit (xprintsym): Don't attempt to print the
        symbol's name if it is not yet set.  This happens with
        built-in symbols at the beginning of 'main'.

        Problem reported by Jeffrey Walton in:
        https://lists.gnu.org/r/emacs-devel/2019-05/msg00041.html
        * Makefile.in (CHECK_TARGETS): New macro; use it
        to simplify 'check' and similar rules.
        ($(CHECK_TARGETS)): If tests are missing, do not fail
        after issuing a diagnostic.  Just skip the tests.

2019-05-03  Paul Eggert  <eggert@cs.ucla.edu>

        Modernize INSTALL a bit

        * INSTALL: Omit filesystem space estimates.  These estimates
        were (1) wrong and (2) no longer important nowadays, as people
        have plenty of space.  Instead, start with how to get and
        unpack an Emacs tarball.  Don’t say "disk" as it’s often not
        disk nowadays.  Update URLs.

2019-05-03  Paul Eggert  <eggert@cs.ucla.edu>

        Simplify use of NDEBUG in etags.c

        * lib-src/etags.c [!DEBUG]: Do not define NDEBUG,
        as that’s conf_post.h’s job now.
        [NDEBUG]: Do not redefine ‘assert’, as that works around
        ancient bugs (e.g., sunos4 pcc) that don’t matter any more,
        as can be seen that other Emacs source files that successfully
        use assert.h without this workaround.

2019-05-03  Paul Eggert  <eggert@cs.ucla.edu>

        Pacify librsvg 2.45.1 and later

        * src/image.c (svg_load_image): Pacify librsvg 2.45.1 and later,
        and add a FIXME comment about the deprecated librsvg functions.

2019-05-03  Paul Eggert  <eggert@cs.ucla.edu>

        Simplify xd_signature to pacify GCC 9

        * src/dbusbind.c (xd_signature): Use simpler way to set up
        the subsignature.  This also pacifies GCC 9 on Fedora 30 x86-64.

2019-05-03  Paul Eggert  <eggert@cs.ucla.edu>

        Update from Gnulib

        This incorporates:

        Remove duplicated and unused code.

        Allow project-find-regexp'ing inside an ignored dir

        * lisp/progmodes/project.el (project-find-regexp): Don't pass
        project's ignores to project--files-in-directory.  The FILES glob
        should be enough, and we don't want to prohibit searching inside
        ignored directories this way (it can be counter-intuitive).

2019-05-02  Dmitry Gutov  <dgutov@yandex.ru>

        (xref--mouse-2): Fix not to jump to the next line

        Fix fontification of first item in CC Mode macro without parentheses

        * lisp/progmodes/cc-engine.el (c-find-decl-prefix-search): Handle the new
        matching possibility (of a #define construct) in the new
        c-decl-prefix-or-start-re.
        (c-find-decl-spots): Allow the initial search for an in-macro starting point
        settle on the # of #define, to facilitate the regexp matching in
        c-find-decl-prefix-search.

        * lisp/progmodes/cc-langs.el (c-anchored-hash-define-no-parens): New lang
        const.

        (c-decl-prefix-or-start-re): Enhance also to match "#define <identifier>".
        (c-dposr-cpp-macro-depth): New lang variable and lang constant.

2019-05-02  Stefan Monnier  <monnier@iro.umontreal.ca>

        * lisp/mail/footnote.el: Add TEXT and POINTERS together

        Rather than adding POINTERS and TEXT separately to footnote--markers-alist,
        add them together, so we don't need footnote--first-text-marker because
        the TEXT part is never nil.

        (footnote--insert-numbered-footnote): Return marker.
        (footnote--insert-text-marker, footnote--insert-pointer-marker):
        Delete functions.
        (footnote--insert-markers): New function to replace them.
        (footnote--insert-footnote): Adjust accordingly.
        Simplify pointless `unless`.
        (footnote--first-text-marker): Remove.  Replace all calls by
        (cadr (car footnote--markers-alist)) or just footnote--markers-alist.

2019-05-02  Alan Mackenzie  <acm@muc.de>

        CC Mode: Fix multiline block comments in macros.

        In particulr, handle multiline block comments whose newlines are not escaped.
        There is an example of this in #define EXTRA_CONTEXT_FIELDS in editfns.c.

        * lisp/progmodes/cc-engine.el (c-beginning-of-macro, c-end-of-macro): Enclose
        the loops scanning escaped newlines with outer loops which check
        heuristically for, respectively, a block comment ender and a block comment
        starter on the lines we end up on.  (A rigorous syntactic check would be too
        slow, here.)

        * lisp/progmodes/cc-langs.el (c-last-c-comment-end-on-line-re)
        (c-last-open-c-comment-start-on-line-re): New language constants/variables.

2019-05-02  Stefan Monnier  <monnier@iro.umontreal.ca>

        * lisp/mail/footnote.el: Tweak markers convention

        Instead of using markers that are sometimes before and sometimes after
        the [...] and using `insert-before-markers` to make sure those that are
        are before stay before, always place them before, and make them
        "move after"so they stay with their [...] without the need for
        insert-before-markers.

        (footnote--current-regexp): Add arg to match previous style.
        Include the start/end "tags" in the regexp.  Adjust all callers.
        (footnote--markers-alist): Change position of POINTERS.
        (footnote--refresh-footnotes, footnote--renumber)
        (footnote--make-hole, footnote-delete-footnote)
        (footnote-back-to-message): Adjust accordingly, mostly by using
        `looking-at` instead of `looking-back`.
        (footnote--make-hole): Always return footnote nb to use.
        (footnote-add-footnote): Simplify call accordingly.

        * test/lisp/mail/footnote-tests.el: New file.

        New functions.

2019-05-02  Stefan Monnier  <monnier@iro.umontreal.ca>

        * lisp/mail/footnote.el: Use dolist and hoist regexps out of loops

        (footnote--refresh-footnotes): Use pcase-dolist; compute regexp once
        outside of the loops.  Use less confusing `literal` arg to `replace-match`
        and specify `fixedcase` since footnote--index-to-string already chose
        the proper case for us.
        (footnote--renumber): Use dolist; compute regexp once
        outside of the loops; shortcircuit when number is unchanged.
        (footnote--text-under-cursor): Rewrite.
        (footnote--make-hole): Use dolist.
        (footnote-add-footnote): CSE.
        (footnote-delete-footnote): Use dolist; compute regexp once
        outside of the loop.
        (footnote-delete-footnote): Don't renumber if there's no footnote left.
        (footnote-renumber-footnotes): Use dolist.

        Consolidate footnote-text-marker-alist and footnote-pointer-marker-alist
        into a single footnote--markers-alist.

        (footnote--markers-alist): New var.

        (footnote--insert-text-marker, footnote--insert-pointer-marker):
        Add to footnote--markers-alist instead.

        case, and not ignoring it causes encode-time to not invert
        decode-time on some platforms (Bug#35502).

        * lisp/progmodes/cc-fonts.el (c-font-lock-enum-body)
        (autodoc-font-lock-line-markup): As part of the `while' condition, check that
        the previous iteration of the loop hasn't moved point past `limit', thus
        obviating "wrong side of point" errors in re-search-forward, etc.

2019-04-30  Mattias Engdegård  <mattiase@acm.org>

        Don't poll auto-revert files that use notification (bug#35418)

        It is a waste to periodically poll files that use change notification
        in auto-revert mode; stop doing that.  If no files need polling,
        turn off the periodic execution entirely to further avoid wasting power.
        Use a timer to inhibit immediate reversion for some time after a
        notification, for throttling.

        This change does not apply to files in global-auto-revert-mode, where

        Port to Oracle Developer Studio 12.6

        This compiler is a bit pickier about checking conformance to
        the C standard, ranging from syntax trivia (no extra ";" at
        the top level) to portability trivia (warnings re conversion
        between function and data pointers) to more-important stuff
        like lack of support for some __attribute__ usages.
        * src/dynlib.c (dynlib_addr): First argument is a function
        pointer, not a data pointer.  All callers changed.
        * src/emacs-module.c (module_function_address):
        Return module_funcptr, not void *.  All uses changed.
        * src/lisp.h (module_funcptr) [HAVE_MODULES]: New type.
        * src/lread.c (union ieee754_double): Don’t assume the usual
        semantics for converting signed to unsigned int when initializing
        a bitfield, as the Oracle compiler complains and the C standard
        is unclear.
        * src/pdumper.c (ALLOW_IMPLICIT_CONVERSION): Make it clearer
        that -Wsign-conversion is disabled everywhere in this file.
        (dump_trace, dump_tailq_prepend, dump_tailq_append):
        Don’t assume __attribute__.

        warnings; it’s not needed here.
        (DEFINE_FROMLISP_FUNC): Avoid possible signal in integer
        conversion from unsigned to signed.
        (DEFINE_FROMLISP_FUNC, finish_dump_pvec): Avoid warning about
        unreachable statements on platforms not supporting the

        Omit stray semicolon that violates C standard.
        (dump_metadata_for_pdumper): Add cast to pacify compiler complaining
        about conversion from function pointer to data pointer.

        Unbreak build when building without GMP support.

        Add support for a new preprocessor macro EMACS_MODULE_HAVE_MPZ_T to

2019-04-24  Philipp Stephani  <phst@google.com>

        Add conversions to and from struct timespec to module interface.

        Time values are a fundamental data type, and such conversions are hard
        to implement within modules because of the various forms of time
        values in Emacs Lisp.  Adding dedicated conversion functions can
        significantly simplify module code dealing with times.

        This approach uses nanosecond precision.  While Emacs in theory has
        support for higher-precision time values, in practice most languages
        and standards, such as POSIX, C, Java, and Go, have settled on
        nanosecond-precision integers to represent time.

        * src/emacs-module.h.in: Add header for struct timespec.

        * src/module-env-27.h: Add module functions for time conversion.

        (mod-test-add-nanosecond/nil, mod-test-add-nanosecond/invalid): New
        unit tests.

        * doc/lispref/internals.texi (Module Values): Document time
        conversion functions.

        Revert "Remove font.c code commented out for a decade"

        This reverts commit 64d0cd9810af6bd0c378fc6bc666c76ddfa97e40.

        Rationale: any font-related code and comments, even if unused
        for decades, serves as important source of useful information
        in an area of Emacs code that is notoriously under-documented.

        Please do NOT remove this stuff until we have an active
        expert in this are on board, who will then decide whether
        this can be retired.

        Thanks to Dmitry Gutov <dgutov@yandex.ru> for running many
        benchmarks and for useful discussions.
        * src/json.c (json_make_string): Speed up parsing of JSON
        strings by optimizing the normal case of a valid UTF-8 string
        being returned from libjansson.  (Bug#31138)

2019-04-23  Philipp Stephani  <phst@google.com>

        Small fix for a JSON unit test.

        * test/src/json-tests.el (json-parse-string/null): Make JSON object
        syntactically valid.  This test is supposed to check whether an
        escaped null character causes an error, but without quoting the string
        it would be syntactically invalid in any case.

2019-04-23  Alan Mackenzie  <acm@muc.de>

        Optimize for typing characters into long C++ raw strings.

        * lisp/progmodes/cc-fonts.el (c-font-lock-complex-decl-prepare)
        (c-font-lock-objc-methods) (c-font-lock-declarations, c-font-lock-enum-tail)
        (c-font-lock-cut-off-declarators, c-font-lock-enclosing-decls): If the chunk
        been fontified consists entirely of comments and strings, don't attempt to
        perform the function's action.

        * lisp/progmodes/cc-mode.el (c-before-change-check-unbalanced-strings): Don't
        expand (c-new-BEG c-new-END) unnecessarily to the entire raw string being
        fontified.
        (c-fl-decl-start, c-fl-decl-end): When in a (raw or otherwise) string, don't
        return a position outside of the string (which used to cause unneeded
        fontification).

        Release xft_data in widget destroy callback to avoid visual distraction

        * lwlib/lwlib-int.h (struct _widget_instance) [HAVE_XFT]: Remove nr_xft_data.
        * lwlib/lwlib-Xaw.c (find_xft_data, xaw_update_one_widget) [HAVE_XFT]: Loop
        while widget member is not NULL instead of using nr_xft_data.
        (xaw_destroy_instance) [HAVE_XFT]: Move xft_data release code from here ...
        (destroy_xft_data) [HAVE_XFT]: ... to here.
        (make_dialog) [HAVE_XFT]: Add destroy_xft_data as destroy callback for dialog.

2019-04-22  Paul Eggert  <eggert@cs.ucla.edu>

        Let plain ‘make’ work even not GNU Make

        * Makefile.in (top_distclean): Clean makefile as well as Makefile.
        * configure.ac: If not using plain ‘make’, create a makefile
        so that plain ‘make’ simply calls $(MAKE).

2019-04-22  Paul Eggert  <eggert@cs.ucla.edu>

        Revert Vinternal_interpreter_environment tweak

        Stefan Monnier pointed out examples like (funcall `(closure
        ,(let ((cycle (list nil))) (setcdr cycle cycle)) () a)),
        where the user can set Vinternal_interpreter_environment
        indirectly.
        * src/eval.c (Fsetq): Revert recent change, going back to Fassq.

2019-04-22  Paul Eggert  <eggert@cs.ucla.edu>

        Improve UBSan discussion in etc/DEBUG

        * etc/DEBUG: Improve -gdwarf-N documentation.
        Go into more detail about UndefinedBehaviorSanitizer.

2019-04-22  Paul Eggert  <eggert@cs.ucla.edu>

        Tweak Vinternal_interpreter_environment lookup

        * src/eval.c (Fsetq, eval_sub): Use assq_no_quit instead
        of Fassq for a list that cannot contain cycles or be that long.

2019-04-22  Paul Eggert  <eggert@cs.ucla.edu>

        Improve wur coverage on older GCCs

        * src/conf_post.h (__has_attribute_warn_unused_result):
        New macro for compilers lacking __has_attribute.
        * src/systhread.h (__has_attribute): Remove ineffective define.
        (ATTRIBUTE_WARN_UNUSED_RESULT): Work better on GCC 3.4 thru 4.

2019-04-22  Paul Eggert  <eggert@cs.ucla.edu>

        Go back to old way of checking json int range

        Although the lisp.h macros really need improvement,
        INTEGER_TO_INT is not the right way to go about it, as it
        causes conversion from intmax_t to uintmax_t and back again,
        which can cause a signal if the value is negative.
        * src/lisp.h (INTEGER_TO_INT, ranged_integer_to_int)
        (ranged_integer_to_uint): Remove, reverting recent changes to
        this file.
        * src/json.c (lisp_to_json): Revert to previous code,
        as the change messes up with uintmax_t<->intmax_t conversion.

2019-04-22  Philipp Stephani  <phst@google.com>

        * src/lisp.h (INTEGER_TO_INT): Fix bug.

2019-04-22  Mattias Engdegård  <mattiase@acm.org>

        Precise handling of filenotify `stopped' events

        * lisp/autorevert.el (auto-revert-notify-handler):
        When getting a `stopped' event, deal with it for the buffers it applies to,
        rather than for all buffers in auto-revert mode.

2019-04-22  Mattias Engdegård  <mattiase@acm.org>

        * lisp/autorevert.el (auto-revert-notify-rm-watch): Simplify.

2019-04-22  Mattias Engdegård  <mattiase@acm.org>

        Revert "Don't remove notify descriptor that is already gone"

        This reverts commit e9e807e9317ca7aa99a5dd220ee8586f8f4331bf,
        which is no longer necessary as `file-notify-rm-watch' has been
        made robust against reentry.

2019-04-22  Mattias Engdegård  <mattiase@acm.org>

        Make file-notify-rm-watch robust against reentry

        Allow file-notify callbacks to call `file-notify-rm-watch', harmlessly,
        after receiving a `stopped' event without triggering recursion.

        * lisp/filenotify.el (file-notify--watch): Note that `callback' can be nil.
        (file-notify--rm-descriptor): Set the `callback' field to nil before
        sending `stopped'.
        (file-notify-rm-watch): Don't do anything if the `callback' field is nil.

2019-04-22  Philipp Stephani  <phst@google.com>

        Introduce a helper macro to convert a Lisp integer to a C integer.

        This is similar to CONS_TO_INTEGER.  The inverse (INT_TO_INTEGER)
        already exists.

        * src/lisp.h (INTEGER_TO_INT): New macro.
        (ranged_integer_to_int, ranged_integer_to_uint): New
        functions.

        * src/json.c (lisp_to_json): Use helper macro.

2019-04-22  Philipp Stephani  <phst@google.com>

        Improve documentation around standard error pipes (Bug#35328).

        * doc/lispref/processes.texi (Asynchronous Processes): Document
        existence and properties of the standard error process.
        (Accepting Output): Document that one has to accept output from the
        standard error process separately.

2019-04-22  Philipp Stephani  <phst@google.com>

        Module API: Don’t require null-terminated strings in make_string.

        * src/emacs-module.c (module_make_string): Use make_unibyte_string, which
        doesn’t require its argument to be null-terminated.  Since it always
        returns a heap-allocated string, we don’t have to copy it any more
        while decoding.
        (module_decode): New helper function.

2019-04-22  Philipp Stephani  <phst@google.com>

        Use utf-8-unix for coding system conversions in the module API.

        Factor out conversions into helper functions to provide a simpler
        interface.

        * src/emacs-module.c (module_encode, module_decode_copy): New helper
        functions.
        (module_make_function, module_copy_string_contents)
        (module_make_string): Use them.

2019-04-22  Basil L. Contovounesios  <contovob@tcd.ie>

        Improve pure and side-effect-free docs

        For discussion, see thread starting at:
        https://lists.gnu.org/r/emacs-devel/2019-04/msg00316.html
        * doc/lispref/customize.texi (Composite Types): Do not overspecify
        :match-alternatives predicates.
        * doc/lispref/eval.texi (Intro Eval): Anchor definition of "side
        effect" for cross-referencing...
        * doc/lispref/functions.texi (What Is a Function): ...from here.
        Define what a pure function is.
        * doc/lispref/internals.texi (Writing Emacs Primitives): Describe
        currently preferred approach to marking primitives as pure and
        side-effect-free.
        * doc/lispref/symbols.texi (Standard Properties): Expand description
        of pure and side-effect-free properties.

2019-04-22  Philipp Stephani  <phst@google.com>

        Refactoring: Inline a few macros.

        Now that CATCHER_ALL catches signals as well, we can simplify
        MODULE_HANDLE_NONLOCAL_EXIT a bit.

        * src/emacs-module.c (MODULE_SETJMP, MODULE_SETJMP_1): Remove.
        (MODULE_HANDLE_NONLOCAL_EXIT): Inline MODULE_SETJMP and
        MODULE_SETJMP_1.

2019-04-22  Michael Albinus  <michael.albinus@gmx.de>

        Some changes in tramp-tests

        * test/lisp/net/tramp-tests.el (tramp-test32-shell-command):
        Check for backward compatibility.
        (tramp-test33-environment-variables): Apply a better check for
        unset variable.

2019-04-21  Paul Eggert  <eggert@cs.ucla.edu>

        Mention AddressSanitizer etc. in etc/DEBUG

        * etc/DEBUG: Modernize for AddressSanitizer etc.
        * etc/NEWS: Defer to etc/DEBUG for this.

2019-04-21  Paul Eggert  <eggert@cs.ucla.edu>

        Remove --enable-checking=xmallocoverrun

        It doesn’t work anymore, and these days ‘gcc -fsanitize=address’
        does a better job anyway.
        * configure.ac: Remove the option.
        * configure.ac (ac_xmalloc_overrun, XMALLOC_OVERRUN_CHECK):
        * src/alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD)
        (XMALLOC_OVERRUN_CHECK_SIZE, XMALLOC_OVERRUN_SIZE_SIZE)
        (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer)
        (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
        (overrun_check_realloc, overrun_check_free):
        Remove.  All uses removed.
        * etc/NEWS: Mention this.

2019-04-21  Paul Eggert  <eggert@cs.ucla.edu>

        Remove --enablechecking=conslist configure option

        * configure.ac: Remove the option.
        * configure.ac (ac_gc_check_cons_list, GC_CHECK_CONS_LIST):
        * src/alloc.c (check_cons_list) [GC_CHECK_CONS_LIST]:
        * src/lisp.h (lisp_h_check_cons_list, check_cons_list):
        Remove.  All uses removed.
        * etc/NEWS: Mention this.

2019-04-21  Paul Eggert  <eggert@cs.ucla.edu>

        Simplify XPNTR

        Because XPNTR now uses ATTRIBUTE_NO_SANITIZE_UNDEFINED,
        it can be simplified.
        * src/alloc.c (macro_PNTR_ADD, PNTR_ADD, macro_XPNTR): Remove.
        (XPNTR): Open-code rather than using the removed macros and
        functions.  Also, simplify by using LISP_WORD_TAG.

2019-04-21  Paul Eggert  <eggert@cs.ucla.edu>

        Fix drain_reloc_list alignment bug

        * src/pdumper.c (dump_charset): Use alignof (struct charset),
        not alignof (int), since struct charset might be more strictly
        aligned than int.  I think this is just a minor performance
        issue, but we might as well use the correct alignment.
        (drain_reloc_list): Use an alignment instead of a size for the
        output alignment.  This prevents undefined behavior when
        alignof (struct emacs_reloc) == 8 and sizeof (dump_off) == 4
        when building on x86-64 with gcc -fsanitize=undefined.

2019-04-21  Paul Eggert  <eggert@cs.ucla.edu>

        Port dump_bitset_clear to -fsanitize=undefined

        * src/pdumper.c (dump_bitset_clear):
        Pacify -fsanitize=undefined by avoiding memset (NULL, x, 0),
        which strictly speaking has undefined behavior although it
        works on all production platforms I know.

2019-04-21  Paul Eggert  <eggert@cs.ucla.edu>

        Port to recent gcc -fsanitize=undefined

        * src/alloc.c (XPNTR): Add ATTRIBUTE_NO_SANITIZE_UNDEFINED and
        remove ATTRIBUTE_UNUSED.  Do not define as a macro, so that
        ATTRIBUTE_NO_SANITIZE_UNDEFINED works.
        * src/lisp.h (lisp_h_XSYMBOL): Remove.  All uses removed.
        With recent GCC the macro does not work with -fsanitize=undefined,
        and the macro can be omitted as its only function is to optimize -O0.

2019-04-21  Basil L. Contovounesios  <contovob@tcd.ie>

        Move side-effect-free from unsafep.el to subr.el

        * lisp/emacs-lisp/unsafep.el: Move side-effect-free property setting
        from here...
        * lisp/subr.el: ...to here, as function declarations for modularity.

2019-04-21  Paul Eggert  <eggert@cs.ucla.edu>

        Revert the double-free bug that I introduced in
        2019-03-11T15:20:54Z!eggert@cs.ucla.edu.
        * src/pdumper.c (dump_mmap_reset): Do not free the private member;
        that’s the release function’s job.
        (dump_mm_heap_cb_release): Free cb if its refcount goes to zero.
        (dump_mmap_contiguous_heap): Mention memory leak in comment.

        Remove some ineffective #ifdefs.

        Since DEFSYM doesn't by itself do anything and make-docfile ignores
        preprocessor statements, conditional compilation of DEFSYMs is
        ineffective.

        * src/data.c (syms_of_data): Remove ineffective #ifdefs.

2019-04-19  Philipp Stephani  <phst@google.com>

        Remove some #ifdefs for user pointers.

        Even if Emacs is compiled without module support, we don't have to
        comment out every bit of user pointer support.  Defining the basic
        structures and functions and detecting user pointers in switch
        statements is harmless, and we're already doing the same for module
        functions.  Removing these #ifdefs makes the code a bit easier to
        read.

        * src/alloc.c (mark_maybe_pointer): Remove special-casing of tagged

        Fix comment and tweak eval_sub

        * src/eval.c (eval_sub): Check whether Fassq returns Qnil,

        nowadays.  Remove incorrect comment “only original_fun and

2019-04-19  Philipp Stephani  <phst@google.com>

        Refactoring: simplify definition of some internal variables.

        In some cases, we never specbind internal objects, so they don't have
        to be symbols.  Rather than using DEFSYM/DEFVAR and then uninterning
        the symbols, use plain static variables.  Call staticpro for all of
        them, to protect them from the garbage collector.

        * src/eval.c (syms_of_eval): Use a static variable for
        Qcatch_all_memory_full.

        * src/emacs-module.c (syms_of_module): Use static variables for
        Vmodule_refs_hash, Vmodule_runtimes, and Vmodule_environments.

2019-04-18  Philipp Stephani  <phst@google.com>

        Refactoring: have CATCHER_ALL also catch signals.

        In all cases where we use a CATCHER_ALL handler we also want to catch
        signals.  Therefore have 'signal' respect CATCHER_ALL.  Adapt internal

        nonlocal exits in CATCHER_ALL handlers.

        * src/lisp.h (enum nonlocal_exit): New enum.
        (struct handler): Add member 'nonlocal_exit' to hold the type of
        nonlocal exit during stack unwinding.

        (unwind_to_catch): Store nonlocal exit type in catch structure.

        Let debugger handle process spawn errors on w32 (Bug#33016)

        Since child_setup() is called between block_input()...unblock_input(),
        when an error is signaled the Lisp debugger is prevented from
        starting.  Therefore, let the callers signal the error instead (which
        they already do for non-w32 platforms, just the error message needs an
        update).
        * src/callproc.c (child_setup) [WINDOWSNT]: Don't call
        report_file_error here.
        (call_process) [WINDOWNT]:
        * src/process.c (create_process) [WINDOWSNT]: Call report_file_errno
        here instead, after the unblock_input() call, same as for !WINDOWSNT.
        * src/lisp.h (CHILD_SETUP_ERROR_DESC): New preprocessor define.  Flip
        the containing ifndef DOS_NT branches so that it's ifdef DOS_NT.
        * src/eval.c (when_entered_debugger): Remove.
        (syms_of_eval) <internal-when-entered-debugger>: Define it as a Lisp
        integer variable instead.
        (maybe_call_debugger): Update comment.
        * test/src/process-tests.el (make-process-w32-debug-spawn-error):

        Bump minimum GTK versions to 2.24 and 3.10

        * configure.ac: Bump required GTK 2 and GTK 3 versions and the
        associated GLib versions. Remove obsolete AC_CHECK_FUNCS calls. These
        check for functions available in later GTK 2 versions. These checks
        and can safely be removed with the exception of
        gtk_window_set_has_resize_grip, which according to a comment in
        gtkutil.c causes an issue in Ubuntu's GTK 2.

        * src/gtkutil.c:

        Add extra text property to fix issue with js2-mode integration

        * lisp/progmodes/js.el (js-jsx--put-syntax-table): New function for
        consistently ensuring smooth js2-mode integration.  js2-mode sets
        syntax-table temporarily while parsing buffers—seemingly to recover
        from parsing interruptions—and then it later clears syntax-table
        blindly.  When integrating with js-mode, this means that unterminated
        string quotes are re-broken in JSX (i.e., they become strings again,
        often stringifying large regions of the buffer which should not be
        strings).  We try to treat quotes in JSXText as non-strings by setting
        syntax-table to a non-“string quote” syntax class, but that stops
        working if we lose the property.  On the js2-mode end, by scanning for
        this second js-jsx-syntax-table property, we can recover the
        syntax-table property there.
        (js-jsx--text-range, js-jsx--syntax-propertize-tag): Use
        js-jsx--put-syntax-table for above reason.
        (js-jsx--text-properties): Clear the js-jsx-syntax-table property too.

        Remove the need for temacs.in

        Instead of building a file temacs.in used only to compute a
        fingerprint, compute the fingerprint directly from the .o and
        .a files that go into temacs.in.  This speeds up the build by
        avoiding the need to link temacs twice, once with a dummy
        fingerprint.
        * lib-src/make-fingerprint.c (main): No need to generate
        a fingerprint file that includes config.h, now that fingerprint.c
        depends on all the .o files.
        * src/Makefile.in ($(libsrc)/make-fingerprint$(EXEEXT)):
        Use the same rule as $(libsrc)/make-docfile$(EXEEXT).
        * src/fingerprint-dummy.c: Remove.
        * src/Makefile.in (${charsets}, $(libsrc)/make-docfile$(EXEEXT))

        (../config.status, ${ETAGS}, ../lisp/TAGS, $(lwlibdir)/TAGS)
        ($(lispsource)/loaddefs.el):
        Prefer ‘$(MAKE) -C $(dir $@)’ to ‘${MAKE} -C SOMESTRING’ when
        either will do, as the former is more regular and lets us
        coalesce rules better.
        (EMACS_DEPS_PRE, EMACS_DEPS_POST, BUILD_EMACS_PRE)
        (BUILD_EMACS_POST, temacs.in$(EXEEXT)): Remove.
        (FINGERPRINTED): New macro.
        (fingerprint.c): Use it instead of temacs.in$(EXEEXT), to
        avoid the need to build temacs.in at all.
        (temacs$(EXEEXT)): No need to depend on other .o files now;
        fingerprint.o is enough, since it depends on the rest.
        Spell out what used to be in BUILD_EMACS_PRE and BUILD_EMACS_POST.
        (mostlyclean): No need to remove temacs.in.

        Remove assumption of uint64_t etc. in portable code

        C11 doesn’t guarantee the existence of types like uint64_t,
        so avoid these types in portable code, as it’s easy to do so.
        There’s no need to avoid the types in w32-specific code,
        since w32 is guaranteed to have them.
        * lib-src/make-fingerprint.c (main):
        * src/fingerprint-dummy.c:
        * src/fingerprint.h:
        * src/pdumper.c (dump_fingerprint, struct dump_header):
        Prefer unsigned char to uint8_t in portable code, as either will do.
        Put an "#include <config.h>" in fingerprint.c files, so
        that the corresponding .o file is rebuilt after ./configure is run.
        * lib-src/make-fingerprint.c (main):
        Simplify loop.
        * src/Makefile.in (fingerprint.c): Update atomically.
        * src/pdumper.c: Omit unnecessary check that off_t is the same
        size as int32_t or int64_t, as the code does not rely on this
        assumption.
        (dump_off): Use int_least32_t, not int32_t.
        (struct dump_reloc): Use unsigned int, not uint32_t.

        https://lists.gnu.org/r/emacs-devel/2019-03/msg00122.html
        As I’m the main person who’s made changes in this area since
        dmpstruct.h was introduced, I’m the most motivated to clean up
        the situation.
        * make-dist (possibly_non_vc_files): Remove src/dmpstruct.h.
        * src/Makefile.in (dmpstruct_headers, dmpstruct.h): Remove.
        (pdumper.o): Do not depend on dmpstruct.h.

2019-04-08  Jackson Ray Hamilton  <jackson@jacksonrayhamilton.com>

        Explain reasonings for JSX syntax support design decisions

        * lisp/progmodes/js.el: Throughout the code, provide explanations for
        why JSX support was implemented in the way that it was; in particular,
        address the overlap between syntax-propertize-function, font-lock, and
        indentation (as requested by Stefan).

2019-04-08  Jackson Ray Hamilton  <jackson@jacksonrayhamilton.com>

        Move curly functions closer to where they’re used

        * lisp/progmodes/js.el (js-jsx--enclosing-curly-pos)
        (js-jsx--goto-outermost-enclosing-curly): As the code evolved, these
        functions’ definitions ended up being far away from the only places
        where they were used.  Move them there.

2019-04-08  Jackson Ray Hamilton  <jackson@jacksonrayhamilton.com>

        Add open/close parenthesis syntax to “<” and “>” in JSX

        * lisp/progmodes/js.el (js-jsx--syntax-propertize-tag): Like in
        sgml-mode, treat “<” and “>” like open/close parenthesis, making the
        text more navigable via forward-sexp, etc.

2019-04-08  Jackson Ray Hamilton  <jackson@jacksonrayhamilton.com>

        Permit non-ASCII identifiers in JS

        * lisp/progmodes/js.el (js--name-start-re): Generally allow
        identifiers to begin with non-ASCII letters.  This is of particular
        importance to JSX parsing.

        * test/manual/indent/jsx-unclosed-2.jsx: Add test to ensure non-ASCII
        characters are parsed properly.

2019-04-08  Jackson Ray Hamilton  <jackson@jacksonrayhamilton.com>

        Identify JSX strings (for js2-mode)

        * lisp/progmodes/js.el (js-jsx--syntax-propertize-tag): Derived modes
        like js2-mode may use font-lock-syntactic-face-function to apply faces
        to JSX strings (and only JSX strings).  Apply the js-jsx-string text
        property to such strings so they can be distinctly identified.
        (js-jsx--text-properties): Ensure the js-jsx-string text property gets
        cleaned up, too.

2019-04-08  Jackson Ray Hamilton  <jackson@jacksonrayhamilton.com>

        Properly set a dynamic, syntactic mode name

        Use mode-line-format constructs to properly set mode-name, rather than
        use the very hacky solution that was filling-in for my lack of
        knowledge of this feature.

        * lisp/progmodes/js.el (js--update-mode-name)
        (js--idly-update-mode-name): Remove.

        (js--syntactic-mode-name-part): New helper function for mode-name.
        (js-use-syntactic-mode-name): Helper to set up the dynamic mode-name.

        (js-jsx-enable): Don’t need to call any extra functions now.
        (js-mode): Use the new setup function rather than the old ones.

        (js-jsx-mode): Use the same initial mode name as js-mode so the final
        one is identical for both modes.

2019-04-08  Jackson Ray Hamilton  <jackson@jacksonrayhamilton.com>

        Improve whitespace and unary keyword parsing

        * lisp/progmodes/js.el (js--name-start-chars): Remove, adding these
        chars back to js--name-start-re.
        (js--name-start-re): Add chars back from js--name-start-chars.

        (js-jsx--tag-start-re): Improve regexp to capture the tag name (so it
        can be disambiguated from a unary keyword), to match newlines (which
        are common in this spot), and to require at least one whitespace
        character before the attribute name.

        (js-jsx--matched-tag-type): Ensure the “tag name” isn’t possibly a
        unary keyword.

        (js-jsx--self-closing-re, js-jsx--matching-close-tag-pos): Allow
        whitespace around “<” and “>”.

        * test/manual/indent/jsx-unclosed-2.jsx: Add tests for unary keyword
        and whitespace parsing.

2019-04-08  Jackson Ray Hamilton  <jackson@jacksonrayhamilton.com>

        Optimize js-jsx--enclosing-tag-pos

        * lisp/progmodes/js.el (js-jsx--enclosing-tag-pos): Update docstring
        to be more precise.  Also, remember close tag positions after they’ve
        been calculated once to avoid many redundant calls to
        js-jsx--matching-close-tag-pos.
        (js-jsx--text-properties): Ensure js-jsx-close-tag-pos text properties
        get cleaned up, too.

2019-04-08  Jackson Ray Hamilton  <jackson@jacksonrayhamilton.com>

        Optimize js-jsx--matching-close-tag-pos

        This function’s performance was having a noticeable impact when
        editing large JSX structures.  Improve its performance
        slightly (elapsed time will be cut in half according to ELP).

        * lisp/progmodes/js.el (js-jsx--tag-re): Remove.
        (js-jsx--matched-tag-type): Simplify implementation with respect to
        the new implementation of js-jsx--matching-close-tag-pos.
        (js-jsx--self-closing-re): Simplify regexp slightly in sync with a
        generally simpler matching algorithm.
        (js-jsx--matching-close-tag-pos): Optimize matching algorithm by using
        multiple simple regexp searches, rather than one big complex search.

        * test/manual/indent/jsx-unclosed-2.jsx: Use the term “inequality” and
        add a test for a possible parsing foible.

2019-04-08  Jackson Ray Hamilton  <jackson@jacksonrayhamilton.com>

        Add tests for miscellaneous JSX parsing feats

        * test/manual/indent/jsx.jsx: Add tests for JSXMemberExpression names
        and JSXOpeningFragment/JSXClosingFragment support (already supported).

2019-04-08  Jackson Ray Hamilton  <jackson@jacksonrayhamilton.com>

        Split JSX indentation calculation into several functions

        * lisp/progmodes/js.el (js-jsx--contextual-indentation)
        (js-jsx--expr-attribute-pos, js-jsx--expr-indentation): Extract logic
        from js-jsx--indentation, and improve the logic’s documentation.
        (js-jsx--indentation): Simplify by splitting into several
        functions (see above) and improve the logic’s documentation.

2019-04-08  Jackson Ray Hamilton  <jackson@jacksonrayhamilton.com>

        Indent expressions in JSXAttributes relative to the attribute’s name

        * lisp/progmodes/js.el (js-jsx--syntax-propertize-tag): Refer to the
        beginning of a JSXExpressionContainer’s associated JSXAttribute (so
        line numbers can be calculated later).
        (js-jsx--text-properties): Also clear the new text property
        js-jsx-expr-attribute.

        (js-jsx--indenting): Remove.
        (js-jsx--indent-col, js-jsx--indent-attribute-line): New variables.
        (js-jsx--indentation): Instead of alternating between two separate
        column calculations, neither necessarily correct, bind the JSX column
        such that the second call to js--proper-indentation can use it as a
        base column.
        (js--proper-indentation): Use JSX as the base column for some indents
        while indenting JSX.

        * test/manual/indent/jsx.jsx: Add more tests for expression indents.

2019-04-08  Jackson Ray Hamilton  <jackson@jacksonrayhamilton.com>

        Fix counting of nested self-closing JSXOpeningElements

        * lisp/progmodes/js.el (js-jsx--matching-close-tag-pos): Fix bug where
        self-closing JSXOpeningElements might be missed if one was nested
        within another.

        * test/manual/indent/jsx-self-closing.jsx: Add test for bug concerning
        self-closing JSXOpeningElement counting.

2019-04-08  Jackson Ray Hamilton  <jackson@jacksonrayhamilton.com>

        Indent broken arrow function bodies as an N+1th arg

        * lisp/progmodes/js.el (js--line-terminating-arrow-re): Revise regexp
        for use with re-search-backward.
        (js--looking-at-broken-arrow-function-p): Remove.
        (js--broken-arrow-terminates-line-p): Replacement for
        js--looking-at-broken-arrow-function-p.  Don’t consider whether an
        arrow appears at point (in an arglist); instead, just look for an
        arrow that terminates the line.
        (js--proper-indentation): Use js--broken-arrow-terminates-line-p.

        * test/manual/indent/js.js: Add test for a broken arrow as an N+1th
        arg.

2019-04-08  Jackson Ray Hamilton  <jackson@jacksonrayhamilton.com>

        Rename tests to use the “.jsx” file extension

        * test/manual/indent/js-jsx-quote.js: Renamed to “jsx-quote.jsx”.
        * test/manual/indent/js-jsx-unclosed-1.js: Renamed to
        “jsx-unclosed-1.jsx”.
        * test/manual/indent/js-jsx-unclosed-2.js: Renamed to
        “jsx-unclosed-2.jsx”.
        * test/manual/indent/js-jsx.js: Renamed to “jsx.jsx”.

        * test/manual/indent/jsx-quote.jsx: Renamed from “js-jsx-quote.js”.
        * test/manual/indent/jsx-unclosed-1.jsx: Renamed from
        “js-jsx-unclosed-1.js”.
        * test/manual/indent/jsx-unclosed-2.jsx: Renamed from
        “js-jsx-unclosed-2.js”.
        * test/manual/indent/jsx.jsx: Renamed from “js-jsx.js”.

2019-04-08  Jackson Ray Hamilton  <jackson@jacksonrayhamilton.com>

        Improve JSX syntax propertization

        * lisp/progmodes/js.el (js-jsx--attribute-name-re): New variable.
        (js-jsx--syntax-propertize-tag): Allow “-” in JSXAttribute names.  Fix
        “out of range” error when typing at the end of a buffer.  Fix/improve
        future propertization of unfinished JSXBoundaryElements.

        * test/manual/indent/js-jsx-unclosed-2.js: Add tests for allowed
        characters in JSX.

2019-04-08  Jackson Ray Hamilton  <jackson@jacksonrayhamilton.com>

        Automatically detect JSX in JavaScript files

        * lisp/files.el (auto-mode-alist): Simply enable
        javascript-mode (js-mode) when opening “.jsx” files, since the “.jsx”
        file extension will be used as an indicator of JSX syntax by js-mode,
        and more code is likely to work in js-mode than js-jsx-mode, and we
        probably want to guide users to use js-mode (with js-jsx-syntax)
        instead.  Code that used to work exclusively in js-jsx-mode (if anyone
        ever wrote any) ought to be updated to work in js-mode too when
        js-jsx-syntax is set to t.

        * lisp/progmodes/js.el (js-jsx-detect-syntax, js-jsx-regexps)
        (js-jsx--detect-and-enable, js-jsx--detect-after-change): New
        variables and functions for detecting and enabling JSX.

        (js-jsx-syntax): Update docstring with respect to the widened scope of
        the effects and use of this variable.

        (js-syntactic-mode-name, js--update-mode-name)
        (js--idly-update-mode-name, js-jsx-enable): New variable and functions
        for indicating when JSX is enabled.

        (js-mode): Detect and enable JSX.  Print all enabled syntaxes after
        the mode name whenever Emacs goes idle; this ensures lately-enabled
        syntaxes are evident.

        (js-jsx-mode): Update mode name for consistency with the state in
        which JSX is enabled in js-mode.  Update docstring to suggest
        alternative means of using JSX without this mode.  Going forward, it
        may be best to gently guide users away from js-jsx-mode, since a “one
        mode per syntax extension” model would not scale well if more syntax
        extensions were to be simultaneously supported (e.g. Facebook’s
        “Flow”).

2019-04-08  Jackson Ray Hamilton  <jackson@jacksonrayhamilton.com>

        Finish replacing SGML-based JSX detection with js-mode’s parsing

        This removes the last dependency on sgml-mode for JSX-related logic.

        * lisp/progmodes/js.el (js-jsx--start-tag-re)
        (js-jsx--end-tag-re): Remove.
        (js-jsx--looking-at-start-tag-p)
        (js-jsx--looking-back-at-end-tag-p): Reimplement using text
        properties, using syntax information which ought to be slightly more
        accurate than regexps since it was found by complete parsing.

2019-04-08  Jackson Ray Hamilton  <jackson@jacksonrayhamilton.com>

        Indent JSX as parsed in a JS context

        Fixes the following issues (and re-fixes indentation issues initially
        fixed but later re-broken by previous commits in the process of adding
        comprehensive JSX support):

        - https://github.com/mooz/js2-mode/issues/389#issuecomment-390766873
        - https://github.com/mooz/js2-mode/issues/482
        - Bug#32158
        - https://github.com/mooz/js2-mode/issues/462

        Previously, we delegated to sgml-mode functions for JSX indentation.
        However, there were some problems with this approach:

        - sgml-mode does not anticipate tags inside attributes when indenting,
          which compromises JSX indentation inside JSXExpressionContainers
          inside JSXAttributes.

        - In previous iterations to provide comprehensive JSX support, it
          proved tedious to disambiguate “<” and “>” as JS inequality
          operators and arrow functions from opening and closing angle
          brackets as part of SGML tags.  That code evolved into a more
          complete JSX parsing implementation for syntax-propertize rules for
          font-locking, discarding the superfluous “<”/“>” disambiguation in
          anticipation of using the improved JSX analysis for indentation.

        - Using sgml-mode functions, we controlled JSX indentation using SGML
          variables.  However, JSX is a different thing than SGML; referencing
          SGML in JS was a leaky abstraction.

        To resolve these issues, use the text properties added by the JSX
        syntax-propertize code to determine the boundaries of various aspects
        of JSX syntax, and reimplement the sgml-mode indentation code in
        js-mode with better respect to JSX indentation conventions.

        * lisp/progmodes/js.el (js-jsx-attribute-offset): New variable to
        provide a way for users to still control JSX attribute offsets as they
        could with sgml-attribute-offset before.  The value of this feature is
        dubious IMO, but it’s trivial to keep it, so let’s do it just in case.

        (js-jsx--goto-outermost-enclosing-curly): New function.

        (js-jsx--enclosing-tag-pos): Refactor to be unbounded by curlies, so
        this function can be used to find JSXExpressionContainers within JSX.
        Fix bug where an enclosing JSXElement couldn’t be found when point was
        at the start of its JSXClosingElement.  Return the JSXClosingElement’s
        position as well, so the JSXClosingElement can be identified when
        indenting and be indented like the matching JSXOpeningElement.

        (js-jsx--at-enclosing-tag-child-p): js-jsx--enclosing-tag-pos now
        returns a list rather than a cons, so retrieve the JSXOpeningElement’s
        end position from a list.

        (js-jsx--context, js-jsx--indenting): New function and variable.
        (js-jsx--indentation): New function replacing the prior
        js-jsx--indent* functions and js-jsx-indent-line’s implementation.
        Use the JSX parsing performed in a JS context to more accurately
        calculate JSX indentation than by delegating to sgml-mode functions.
        (js--proper-indentation): Use js-jsx--indentation as yet another type
        of indentation.
        (js-jsx--as-sgml, js-jsx--outermost-enclosing-tag-pos)
        (js-jsx--indentation-type, js-jsx--indent-line-in-expression)
        (js-jsx--indent-n+1th-line): Remove obsolete functions.

        (js-jsx-indent-line): Refactor nearly-obsolete function to behave the
        same as it usually would before these changes, without respect to the
        binding of js-jsx-syntax.

        (js-jsx-mode): Remove obsolete documentation about the use of SGML
        variables to control indentation, and don’t bind indent-line-function
        any more, because it is no longer necessary given the new
        implementation of js-jsx-indent-line.

        Update expectations for JSX indentation in JSXAttribute space

        * test/manual/indent/js-jsx.js: Align expectations for dangling
        closing constructs with other places in the tests.

2019-04-08  Jackson Ray Hamilton  <jackson@jacksonrayhamilton.com>

        Propertize and font-lock JSXText and JSXExpressionContainers

        This completes highlighting support for JSX, as requested in:

        - https://github.com/mooz/js2-mode/issues/330
        - https://github.com/mooz/js2-mode/issues/409

        * lisp/progmodes/js.el (js--name-start-chars): Extract part of
        js--name-start-re so it can be reused in another regexp.
        (js--name-start-re): Use js--name-start-chars.

        (js-jsx--font-lock-keywords): Use new matchers.
        (js-jsx--match-text, js-jsx--match-expr): New matchers to remove
        typical JS font-locking and extend the font-locked region,
        respectively.

        (js-jsx--tag-re, js-jsx--self-closing-re): New regexps matching JSX.
        (js-jsx--matched-tag-type, js-jsx--matching-close-tag-pos)
        (js-jsx--enclosing-curly-pos, js-jsx--enclosing-tag-pos)
        (js-jsx--at-enclosing-tag-child-p): New functions for parsing and
        analyzing JSX.

        (js-jsx--text-range, js-jsx--syntax-propertize-tag-text): New
        functions for propertizing JSXText.
        (js-jsx--syntax-propertize-tag): Propertize JSXText children of tags.
        (js-jsx--text-properties): Remove JSXText-related text properties when
        repropertizing.
        (js-mode): Extend the syntax-propertize region with
        syntax-propertize-multiline; we are now adding the syntax-multiline
        text property to buffer ranges that are JSXText to ensure the whole
        multiline JSX construct is reidentified.

2019-04-08  Jackson Ray Hamilton  <jackson@jacksonrayhamilton.com>

        Font-lock JSX while editing it by extending regions

        * lisp/progmodes/js.el (js-jsx--font-lock-keywords):
        Call tag beginning and end matchers.
        (js-jsx--match-tag-beg, js-jsx--match-tag-end): New functions.
        (js-jsx--syntax-propertize-tag): Record buffer positions of JSXElement
        beginning and end for font-locking.

        (js--syntax-propertize-extend-region)
        (js-jsx--syntax-propertize-extend-region): New functions for extending
        the syntax-propertize region backwards to the start of a JSXElement so
        its JSXAttribute children on its n+1th lines can be parsed as such
        while editing those lines.
        (js-mode): Add js--syntax-propertize-extend-region to
        syntax-propertize-extend-region-functions.

2019-04-08  Jackson Ray Hamilton  <jackson@jacksonrayhamilton.com>

        Add basic JSX font-locking

        Font-lock JSX from the beginning of the buffer to the end.  Tends to
        break temporarily when editing lines, because the parser doesn’t yet
        look backwards to determine if the end of a tag in the current range
        starts before the range.

        This also re-breaks some tests fixed by previous commits, as we begin
        to take a different direction in our parsing code, looking for JSX,
        rather than for non-JSX.  The parsing code will eventually provide
        information for indentation again.

        * lisp/progmodes/js.el (js--dotted-captured-name-re)
        (js-jsx--disambiguate-beginning-of-tag)
        (js-jsx--disambiguate-end-of-tag, js-jsx--disambiguate-syntax):

        (js--font-lock-keywords-3): Add JSX matchers.
        (js-jsx--match-tag-name, js-jsx--match-attribute-name): New functions.
        (js-jsx--syntax-propertize-tag): New function to aid in JSX
        font-locking and eventually indentation.
        (js-jsx--text-properties): New variable.
        (js-syntax-propertize): Propertize JSX properly using
        syntax-propertize-rules.

        js-syntax-propertize: Disambiguate JS from JSX, fixing some indents

        Fix some JSX indentation bugs:

        - Bug#24896 / https://github.com/mooz/js2-mode/issues/389
        - Bug#30225
        - https://github.com/mooz/js2-mode/issues/459

        * lisp/progmodes/js.el (js--dotted-captured-name-re)
        (js--unary-keyword-re, js--unary-keyword-p)
        (js--disambiguate-beginning-of-jsx-tag)
        (js--disambiguate-end-of-jsx-tag)
        (js--disambiguate-js-from-jsx): New variables and functions.

        (js-syntax-propertize): Additionally clarify when syntax is JS so that
        ‘(with-syntax-table sgml-mode-syntax-table …)’ does not mistake some
        JS punctuation syntax for SGML parenthesis syntax, namely ‘<’ and ‘>’.

        * test/manual/indent/js-jsx-unclosed-2.js: Add additional test for
        unary operator parsing.

2019-04-08  Jackson Ray Hamilton  <jackson@jacksonrayhamilton.com>

        Add new (failing) unclosed JSX test and separate such tests

        * test/manual/indent/js-jsx.js: Move test with intentional scan error to
        its own file, js-jsx-unclosed-1.js.
        * test/manual/indent/js-jsx-unclosed-1.js: New file.
        * test/manual/indent/js-jsx-unclosed-2.js: New file with test for
        regression caused by new ambiguous parsing of JS/JSX.

2019-04-08  Jackson Ray Hamilton  <jackson@jacksonrayhamilton.com>

        Refactor JSX indentation code to improve enclosing JSX discovery

        Fix a number of bugs reported for JSX indentation (caused by poor JSX
        detection):

        - https://github.com/mooz/js2-mode/issues/140#issuecomment-166250016
        - https://github.com/mooz/js2-mode/issues/490
        - Bug#24896 / https://github.com/mooz/js2-mode/issues/389 (with
        respect to comments)
        - Bug#26001 /
        https://github.com/mooz/js2-mode/issues/389#issuecomment-271869380
        - https://github.com/mooz/js2-mode/issues/411 / Bug#27000 /
        https://github.com/mooz/js2-mode/issues/451

        Potentially manifest some new bugs (due to false positives with ‘<’
        and ‘>’ and SGML detection).  Slow down indentation a fair bit.

        * lisp/progmodes/js.el (js-jsx-syntax, js--jsx-start-tag-re)
        (js--looking-at-jsx-start-tag-p, js--looking-back-at-jsx-end-tag-p):
        New variables and functions.
        (js--jsx-find-before-tag, js--jsx-after-tag-re): Deleted.

        (js--looking-at-operator-p): Don’t mistake a JSXOpeningElement for the
        ‘<’ operator.
        (js--continued-expression-p): Don’t mistake a JSXClosingElement as a
        fragment of a continued expression including the ‘>’ operator.

        (js--as-sgml): Simplify.  Probably needn’t bind forward-sexp-function
        to nil (sgml-mode already does) and probably shouldn’t bind
        parse-sexp-lookup-properties to nil either (see Bug#24896).

        (js--outermost-enclosing-jsx-tag-pos): Find enclosing JSX more
        accurately than js--jsx-find-before-tag.  Use sgml-mode’s parsing
        logic, rather than unreliable heuristics like paren-wrapping.  This
        implementation is much slower; the previous implementation was fast,
        but at the expense of accuracy.  To make up for all the grief we’ve
        caused users, we will prefer accuracy over speed from now on.  That
        said, this can still probably be optimized a lot.

        (js--jsx-indented-element-p): Rename to js--jsx-indentation, since it
        doesn’t just return a boolean.
        (js--jsx-indentation): Refactor js--jsx-indented-element-p to simplify
        the implementation as the improved accuracy of other code allows (and
        to repent for some awful stylistic choices I made earlier).

        (js--expression-in-sgml-indent-line): Rename to
        js--indent-line-in-jsx-expression, since it’s a private function and
        we can give it a name that reads more like English.
        (js--indent-line-in-jsx-expression): Restructure point adjustment
        logic more like js-indent-line.

        (js--indent-n+1th-jsx-line): New function to complement
        js--indent-line-in-jsx-expression.

        (js-jsx-indent-line): Refactor.  Don’t bind js--continued-expression-p
        to ignore any more; instead, rely on the improved accuracy of
        js--continued-expression-p.

        (js-jsx-mode): Set js-jsx-syntax to t.  For now, this will be the flag
        we use to determine whether ‘JSX is enabled.’  (Maybe later, we will
        refactor the code to use this variable instead of requiring
        js-jsx-mode to be enabled, thus rendering the mode obsolete.)

2019-04-08  Jackson Ray Hamilton  <jackson@jacksonrayhamilton.com>

        Add failing tests for JSX indentation bugs

        * test/manual/indent/js-jsx.js: Add failing tests for all the js-mode
        and js2-mode JSX indentation bugs reported over the years that I could
        find.  Some may be duplicates, so I have grouped similar reports
        together, for now; we’ll see for certain which distinct cases we need
        once we start actually implementing fixes.
        * test/manual/indent/js-jsx-quote.js: New file with a nasty test.

        Don't check comp-buffer-name-function in derived mode (Bug#34956)

        * lisp/progmodes/compile.el (define-compilation-mode): Remove
        'compilation-buffer-name-function' from the list of overridden
        variables to ensure that it is not mistaken for a variable that can be
        major mode specific.  'compilation-buffer-name-function' is used
        before the major mode is loaded, therefore overriding it here is
        ineffectual.  Also, the function 'compilation-start' takes an optional
        argument name-function, so there is already a mechanism to override
        it.

        More regexp advice and clarifications

        * doc/lispref/searching.texi (Regexp Special): Simplify style
        advice for order of ], ^, and - in character alternatives.
        Stick with saying that it’s not a good idea to put ‘-’ after a
        range.  Remove the special case about raw 8-bit bytes and
        unibyte characters, as this documentation is confusing and
        seems to be incorrect in some cases.  Say that z-a is the
        preferred style for reversed ranges, since it’s clearer and is
        typically what’s used in practice.  Mention some bad styles:
        duplicates in character alternatives, ranges that denote <=3
        characters, and ‘-’ as the first character.

        Make struct Lisp_Objfwd etc. objects read-only

        Initialize these objects statically, and make them constants.
        This is a bit safer and more efficient.
        * src/data.c (XBOOLFWD, XKBOARD_OBJFWD, XFIXNUMFWD, XOBJFWD):
        * src/lisp.h (XBUFFER_OBJFWD):

        responsibility to initialize the pointed-to storage.  No need
        for a separate address argument any more.  All callers
        changed.

2019-04-01  Paul Eggert  <eggert@cs.ucla.edu>

        Fix union Lisp_Fwd * alignment bug

        It's not portable to cast (e.g.) struct Lisp_Objfwd * to union
        Lisp_Fwd * and then back again, because the compiler can then assume
        that the pointer is aligned for union Lisp_Fwd * when accessing
        the struct Lisp_Objfwd * components, and this assumption might
        be incorrect because we don't force that alignment.
        * src/lisp.h (lispfwd): New type, replacing ...
        (union Lisp_Fwd): ... this type, which was removed.
        All uses changed.
        (SET_SYMBOL_FWD): 2nd arg is now void *, not lispfwd.
        All uses changed (casts no longer needed; they were

        Don't run buffer-related hooks in " *code conversion work*" buffers

        Note: portions of this change were mistakenly pushed as part
        of an unrelated commit a35a1f6a9.

        * src/buffer.c (Fget_buffer_create): Set inhibit_buffer_hooks
        non-zero for temporary buffers created by coding.c.  Don't run
        buffer-list-update-hook for such buffers.
        (Frename_buffer, Fkill_buffer, record_buffer)
        (Fbury_buffer_internal): Don't run hooks for buffers whose
        inhibit_buffer_hooks flag is set.

        during encoding/decoding.
        (Vcode_conversion_workbuf_name): Now external variable.
        * src/coding.h (Vcode_conversion_reused_workbuf): Declare.

        Avoid occasional confusion of Flymake C/C++ backend

        The regexp would sometimes match non-errors and create a diagnostic

        Change Gnus hash tables into real hash tables

        Gnus has used obarrays as makeshift hash tables for groups: group
        names are coerced to unibyte and interned in custom obarrays, and
        their symbol-value set to whatever value needs to be stored. This
        patch replaces those obarrays with actual hash tables.

        * lisp/gnus/gnus-util.el (gnus-intern-safe, gnus-create-hash-size):
          Remove functions.
          (gnus-make-hashtable): Change to return a real hash table.
          (gnus-text-property-search): Utility similar to `text-property-any',
          but compares on `equal'. Needed because the 'gnus-group text
          property is now a string.
        * lisp/gnus/gnus.el (gnus-gethash, gnus-gethash-safe, gnus-sethash):
          Remove macros.
          (gnus-group-list): New variable holding all group names as an
          ordered list. Used because `gnus-newsrc-hashtb' used to preserve
          `gnus-newsrc-alist' ordering, but now doesn't.
        * lisp/gnus/nnmaildir.el (nnmaildir--servers): Change from obarray to
          alist.
          (nnmaildir--up2-1): Remove function.
        * lisp/thingatpt.el (thing-at-point-newsgroup-p): This was making use
          of Gnus obarrays, replace with a cond that can handle many different
          possibilities.
        * lisp/gnus/gnus-bcklg.el (gnus-backlog-articles): Remove
          gnus-backlog-hashtb, which wasn't doing anything. Just keep a list
          of ident strings in gnus-backlog-articles.
          (gnus-backlog-setup): Delete unnecessary function.
          (gnus-backlog-enter-article, gnus-backlog-remove-oldest-article,
          gnus-backlog-remove-article, gnus-backlog-request-article): Alter
          calls accordingly.
        * lisp/gnus/gnus-dup.el (gnus-duplicate-list-max-length): Rename from
          `gnus-duplicate-list-length', for accuracy.
        * lisp/gnus/gnus-start.el (gnus-active-to-gnus-format,
          gnus-groups-to-gnus-format, gnus-newsrc-to-gnus-format): Read group
          names as strings.
          (gnus-gnus-to-quick-newsrc-format): Write `gnus-newsrc-alist' using
          the ordering in `gnus-group-list'.
        * lisp/gnus/gnus-agent.el:
        * lisp/gnus/gnus-async.el:
        * lisp/gnus/gnus-cache.el:
        * lisp/gnus/gnus-group.el:

        * lisp/gnus/nnbabyl.el:
        * lisp/gnus/nnvirtual.el:
        * lisp/gnus/nnweb.el: In all files, change obarrays to hash-tables,
          and swap `gnus-sethash' for `puthash', `gnus-gethash' for `gethash',
          `mapatoms' for `maphash', etc.
        * test/lisp/gnus/gnus-test-headers.el (gnus-headers-make-dependency-table,
          gnus-headers-loop-dependencies): New tests to make sure we're
          building `gnus-newsgroup-dependencies' correctly.

2019-03-22  Michael Albinus  <michael.albinus@gmx.de>

        Fix Bug#24394, Bug#34172

        remote buffers, trust settings of `shell-file-name'.

        * lisp/net/tramp-adb.el (tramp-methods) <adb>:
        * lisp/net/tramp-smb.el (tramp-methods) <smb>:

        * lisp/net/tramp.el (tramp-handle-shell-command): Do not use shell
        file names from `tramp-methods'.
        Respect `async-shell-command-buffer'.  (Bug#24394, Bug#34172)
        Use `start-file-process-shell-command' and `process-file-shell-command'.

        * test/lisp/net/tramp-tests.el (tramp-test32-shell-command):

        * lisp/eshell/esh-proc.el (eshell-query-kill-processes):
        Remove invalid `format-message' call; `eshell-round-robin-kill' wants
        just the format string.

        which prevents the tab -> TAB remapping.
        Use completion-at-point and completion-help-at-point.
        (eshell-complete-commands-list): Use `fboundp` test instead of ugly
        gymnastics to try and hide the function call from the compiler.

2019-03-19  Paul Eggert  <eggert@cs.ucla.edu>

        Use ‘const’ to clarify GC marking

        Add ‘const’ to make the GC marking code a bit clearer.
        This can also help the compiler in some cases, I think because
        GCC can now determine more often that the value of a static C
        variable can be cached when its address is now converted to
        ‘Lisp Object const *’ before escaping.
        * src/alloc.c (staticvec, mark_maybe_objects, mark_memory)

        Disallow reversed char ranges in `rx'

        (any "a-Z0-9") generated "[0-9]", and (any (?9 . ?0)) generated "[9-0]".
        Reversed ranges are either mistakes or abuse.  Neither should be allowed.

        etc/NEWS: Explain the change.

2019-03-18  Paul Eggert  <eggert@cs.ucla.edu>

        Remove buggy regexp use in comint-output-filter

        This reverts commit 2012-07-02T16:18:02!monnier@iro.umontreal.ca
        which perhaps could be rethought and recommitted, and perhaps
        it’s no longer needed now that comint-use-prompt-regexp
        is almost always nil.
        * lisp/comint.el (comint-output-filter): Don’t try to skip
        repeated prompts, since comint-prompt-regexp typically begins
        with "^" and the resulting "^^" in the regular expression does
        not have the desired effect.  Noted by Mattias Engdegård in:

        Simplify list creation in C code

        The main new thing here is that C code can now say
        ‘list (a, b, c, d, e, f)’ instead of
        ‘listn (CONSTYPE_HEAP, 6, a, b, c, d, e, f)’,
        thus relieving callers of the responsibility of counting
        arguments (plus, the code feels more like Lisp).  The old
        list1 ... list5 functions remain, as they’re probably a bit
        faster for small lists.
        * src/alloc.c (cons_listn, pure_listn): New functions.
        (listn): Omit enum argument.
        All callers changed to use either new ‘list’ or ‘pure_list’ macros.

        Parenthesize to avoid expanding new ‘list’ macro.
        * src/gtkutil.c (GETSETUP): Rename from MAKE_FLOAT_PAGE_SETUP
        to get lines to fit.  Move outside the ‘list’ call, since it’s
        now a macro.
        * src/keymap.c (Fmake_keymap): Simplify.
        * src/lisp.h (list, pure_list): New macros.

        obsolete and make it set 'diff-refine' appropriately to keep
        backward compatibility.
        (diff-hunk-next, diff-hunk-prev): Adapt to rename of
        diff-auto-refine-mode and ensure that refining only happens
        when calling these commands interactively.
        (diff--font-lock-refined): Adapt to rename of
        diff-font-lock-refine.
        * lisp/vc/smerge-mode.el (smerge-next, smerge-prev): Check

        rx: fix `or' ordering by adding argument to regexp-opt

        The rx `or' form may reorder its arguments in an unpredictable way,

        Maintain interval ->position fields correctly in update_interval

        Also fix some anomalies in the handling of byte positions in regexp-emacs.c
        This fixes bug #34525.

        * src/intervals.c (SET_PARENT_POSITION): New macro.
        (update_interval): When moving to an interval's parent, set that parent's
        ->position field, to maintain the consistency of the tree.

        * src/intervals.h (struct interval): Amend the comment describing when
        ->position is valid.

        on byte positions.  Correct the argument to an invocation of
        UPDATE_SYNTAX_TABLE_FORWARD by adding 1 to it (in case wordend:).

        * src/syntax.c: (update_syntax_table): Remove the now redundant code that set

        This should help future improvements where these stats can be

        (garbage_collect): New function.  All C callers of
        Fgarbage_collect changed to use it, since none of them use the

        be good enough for these (for a while, anyway...).

        Bug#33975

2019-02-24  Philipp Stephani  <phst@google.com>

        Ignore pending_signals when checking for quits.

        pending_signals is often set if no quit is pending.  This results in
        bugs in module code if the module returns but no quit is actually
        pending.

        As a better alternative, add a new process_input environment function
        for Emacs 27.  That function processes signals (like maybe_quit).

        * configure.ac: Add module snippet for Emacs 27.

        * src/module-env-27.h: New file.

        * src/emacs-module.h.in: Add process_input function to environment
        interface.

        whether the caller should quit.
        (module_process_input): New function.

        * test/data/emacs-module/mod-test.c (signal_wrong_type_argument)
        (signal_errno): New helper functions.

        * test/src/emacs-module-tests.el (mod-test-sleep-until): New unit
        test.

        Don’t assume timersub and gettimeofday

        POSIX does not specify timersub, and marks gettimeofday as

        Prevent over-eager rx character range condensation

        `rx' incorrectly considers character ranges between ASCII and raw bytes to
        cover all codes in-between, which includes all non-ASCII Unicode chars.
        This causes (any "\000-\377" ?Å) to be simplified to (any "\000-\377"),
        which is not at all the same thing: [\000-\377] really means
        [\000-\177\200-\377] (Bug#34492).

        * lisp/emacs-lisp/rx.el (rx-any-condense-range): Split ranges going
        from ASCII to raw bytes.

        Change scoring strategy for 'flex' completion style

        The previous strategy had problems comparing scores of matches to
        strings of different lengths.  This one seems slightly more sensible,
        and uses a new constant `flex-score-match-tightness' instead of the
        more abstract `flex-score-falloff'.

        It's not completely without problems, and I think it shouldn't count
        "holes" at the front and at the back, but that needs a different
        "pattern-to-regexp" conversion in completion-pcm--hilit-commonality.

        (defun test ()
          (mapcar (lambda (a)
                    (cons (substring-no-properties a)
                          (get-text-property 0 'completion-score a)))
                  (sort (completion-pcm--hilit-commonality
                          '(prefix "f" star "o" star "o" point)

                            "barbazfoo"

        Dear eamcs developers, eshells current documentation first states
        that alias definitions are not saved to an alias file, later that
        they are saved to an alias file.  I tested it and the latter is
        correct.

        Please find attached a patch which fixes this.

        Thanks for working on emacs which is really great, Gregor

        Score flex-style completions according to match tightness

        The new completion style needs to score completion matches so that we
        can use it later on when sorting the completions.  This is because
        "foo" can flex-match "foobar", "frodo" and "barfromsober" but we
        probably want "foobar" to appear at the top of the completion list.

        This change introduces a scoring formula and adds scoring hints in the
        candidate string's `completion-score' property.

        * lisp/minibuffer.el (completion-pcm--hilit-commonality): Propertize

        Make window choice in xref commands configurable

        Previously, it wasn't easy to tell xref.el commands like

        choose a window for the *xref* buffer or how to find windows for
        displaying the results after choosing a candidate.  This patch makes

        Make make-dist more automatic

        Simplify make-dist maintenance by having it generate its
        list of files more automatically.  Put the list of distributed
        files into a file MANIFEST that can be used in the unusual
        situations when you’re making a distribution without having
        access to a Git repository.
        * make-dist (top_level_ChangeLog): Now nonempty if the
        distribution tarball will contain a ChangeLog, instead of
        being nonempty when a ChangeLog is requested, Git is present
        and a readable ChangeLog exists.  The new interpretation makes
        the script a bit easier to follow.
        (possibly_non_vc_files, info_files, mkdir_verbose)
        (file_to_skip, MANIFEST_subdir_sed, tempsubdirs):
        New variables.
        (MANIFEST): Update and use this file, which now records what
        files are distributed.
        (top_level, subdir, files, file): Remove.

        * configure.ac (CANNOT_DUMP): Remove.  All uses removed,
        or changed to the negative of with_unexec.
        (HAVE_UNEXEC): New macro.  All uses of CANNOT_DUMP changed
        to the negative of this macro.

        Omit some linker hacks if not doing unexec

        * configure.ac (LDFLAGS, LD_SWITCH_SYSTEM_TEMACS):
        Omit some funky linker flags if not supporting unexec.

        Use macOS linker hacks only if needed
        * configure.ac: On darwin, link with -fno-pie and -headerpad
        only if configuring with unexec.

        Stop using macOS -prebind option

        * configure.ac (LD_SWITCH_SYSTEM_TEMACS): Remove -prebind,
        which has been obsolete and ineffective since Mac OS X 10.4 (2005),
        which was never necessary for correct operation, and which now
        generates annoying warnings.  Problem reported by Robert Pluim in:

        * src/emacs.c (load_pdump): Support the use case where the
        Emacs binary was renamed: look in exec-directory for the

        in addition to just emacs.pdmp.

        Adjust previous electric.el and elec-pair.el change

        This fixes a serious bug introduced previously
        electric-pair-inhibit-if-helps-balance and
        electric-pair-skip-if-helps-balance, whereby "innocent" markers were
        being pushed by those function's new save-change-and-restore
        semantics.  The fix can probably still be improved.

        It also adds comments to parts of the code, where deemed necessary.

        * lisp/elec-pair.el (electric-pair--insert): Add comment.
        (electric-pair--save-literal-point-excursion): New helper macro.
        (electric-pair-inhibit-if-helps-balance)
        (electric-pair-skip-if-helps-balance): Don't use
        insert-before-markers since it may hurt other markers that have
        nothing to do with the 'save-excursion'.
        (electric-pair-post-self-insert-function): Use
        electric-pair--save-literal-point-excursion.

2019-01-23  Stefan Monnier  <monnier@iro.umontreal.ca>

        Rework last commit to icomplete and minibuffer.el.

        Rather than let minibuffer-force-complete set up cycling and then undoing it,
        better tell it directly not to setup cycling.  Also be a bit more careful
        to remove the transient map.
        Additionally to bug#34077 and bug#34116, this also relates to bug#25644.

        * lisp/minibuffer.el (completion--flush-all-sorted-completions):
        Also take down the transient cycling map if applicable.
        (minibuffer-force-complete): New arg dont-cycle.
        Set completion-cycling to the actual function that takes down the
        transient map rather than just t.
        (minibuffer-force-complete-and-exit):
        * lisp/icomplete.el (icomplete-force-complete): Use new dont-cycle arg.

2019-01-23  João Távora  <joaotavora@gmail.com>

        Force completion in icomplete with C-M-i, but don't cycle (bug#34077)

        Cycling after forcing a completion with C-M-i in icomplete can be
        confusing, as it leaves rotated prospects in the minibuffer.  In C-x
        C-f, for example it is very difficult to understand if the prospects
        refer to subdirectories of the directory being completed to, which
        happens naturally when the completion is unique; or if they are a
        cycled version of prospects that match the new completion pattern, in
        case the completion happens to still match other items.

        To resolve this confusion, never cycle with C-M-i in icomplete:
        non-ambiguous cycling can be achieved with C-. and C-,

        The former behaviour can still be restored with:

        (define-key icomplete-minibuffer-map (kbd "C-M-i") 'minibuffer-force-complete)

        * lisp/icomplete.el (icomplete-force-complete): New command.
        (icomplete-minibuffer-map): Bind C-M-i to icomplete-force-complete.

        electric-layout-mode kicks in before electric-pair-mode

        This aims to solve problems with indentation.  Previously in, say, a
        js-mode buffer with electric-layout-rules set to

           (?\{ before after)
           (?\} before)

        would produce an intended:

           function ()
           {
             <indented point>
           }

        The initial state

          function () {

        Would go immediately to the following by e-p-m

          function () {}

        Only then would e-l-m be applied to } first, and then again to {.
        This makes lines indent in the wrong order, which can be a problem in
        some modes.

        The way we fix this is by reversing the order of e-p-m and e-l-m in
        the post-self-insert-hook (and also fixing a number of details that
        this uncovered).  In the end this changes the sequence from

          function () {

        By way of e-l-m becomes:

          function () <newline>
          {
          <newline>

        The e-p-m inserts the pair

          function () <newline>
          {
          <newline>}

        And then e-l-m kicks in for the pair again, yielding the desired result

          function () <newline>
          {
          <indented point>
          }

        * lisp/elec-pair.el (electric-pair--insert): Bind
        electric-layout-no-duplicate-newlines.
        (electric-pair-inhibit-if-helps-balance)
        (electric-pair-skip-if-helps-balance): Use insert-before-markers,
        playing nice with save-excurion.
        (electric-pair-post-self-insert-function): Go to correct position
        before checking electric-pair-inhibit-predicate and
        electric-pair-skip-self predicate.
        (electric-pair-post-self-insert-function): Increase priority to
        50.

        * lisp/electric.el (electric-indent-post-self-insert-function):

        (electric-layout-post-self-insert-function-1): Rewrite comments.

        previous line because racecar.

        (electric-modes-int-main-allman-style)

2019-01-22  João Távora  <joaotavora@gmail.com>

        Remove tests of electric-pair-mode and CC-based modes

        The behaviour previously observed in cc-mode-based-modes (and every
        other major-mode) when electric-pair-mode or electric-layout-mode is
        turned on may no longer be observed: this because CC-mode goes around
        the generic implementation of electric-pair-mode.

        An alternative is to bind every delimiter key like '{', '}', etc to
        'self-insert-command, like most major modes already do, at the cost of
        losing c-auto-newline functionality (which was incompatible anyway
        before the recent changes of bug#33794).

        * test/lisp/electric-tests.el
        (electric-pair-test-for): No longer set it.

        Port to platforms where NULL is a pointer

        * src/image.c (x_create_x_image_and_pixmap):
        The Picture type is an integer, not a pointer.
        Come to think of it, Picture is really XID, and as
        far as I can tell, all-bits-one is the invalid XID,
        not all-bits-zero.  However that is a bigger issue;
        for now, this patch just unbreaks the build.

        Fix electric-pair-tests by disabling bug#33794's fix with a variable

        The variable c--disable-fix-of-bug-33794, which should be removed in
        the short term in favor of a permanent solution, is introduced.

        It is bound to nil by default.  This means that breakage is still
        happening in actual c-mode and c++-mode usage, though the tests no
        longer show it.

        To get around this breakage, put

           (setq c--disable-fix-of-bug-33794 t)

        In your init file.  Evidently, you will lose the fix for bug#33794,
        but that only affects a small corner case of c-toggle-auto-newline,
        which is not turned on by default.

        See https://lists.gnu.org/r/emacs-devel/2019-01/msg00360.html
        for more information.

        * lisp/progmodes/cc-cmds.el (c--disable-fix-of-bug-33794): New

        (c-electric-paren, c-electric-brace): Check
        c--disable-fix-of-bug-33794.

        * test/lisp/electric-tests.el (c--disable-fix-of-bug-33794):

        'argmatch' instead.
        (PDUMP_FILE_ARG): Macro removed; use literal strings instead,
        as with other command-line options.  Use HAVE_PDUMPER for cpp
        conditionals which used PDUMP_FILE_ARG.
        (load_pdump, main): Use 'argmatch' for "--dump-file" and
        "--temacs" arguments, thus supporting the "-dump-file" and
        "-temacs" variants, for consistency with other options.
        (main): Remove the extra fatal error for using --dump-file in
        unexec'ed Emacs: load_pdump does that anyway.

        Use emacs_gnutls_handle_error only on errors.
        (emacs_gnutls_read): Retry if gnutls_record_recv returns
        GNUTLS_E_INTERRUPTED, to be consistent with emacs_read.
        (emacs_gnutls_handle_error): Return 0 on fatal errors,
        -1 (setting errno) on ordinary errors, to simplify callers.
        Assume that ERR is negative, since it always is now.
        Map non-fatal GnuTLS errors to errno values as best we can.
        * src/process.c (read_process_output) [DATAGRAM_SOCKETS]:
        Retry recvfrom if it is interrupted, to be consistent with
        how things are handled when not a datagram channel.
        (send_process) [DATAGRAM_SOCEKTS]: If sendto is interrupted,

        List lengths are always fixnums now

        Without this patch, it was theoretically possible for a list
        length to be a bignum, which means that safe-length could
        signal an error (due to generating a too-large bignum) contrary
        to its documentation.  Fix things to remove the theoretical
        possibility, so that list lengths are always fixnums (and so
        that list lengths are always ptrdiff_t values too, since that
        is assumed internally anyway).
        * src/alloc.c (Fcons): Do not allocate so many conses that
        a list length won’t fit into ptrdiff_t or into fixnum.
        This matters only on weird platforms; on typical platforms,
        list lengths always fit anyway.
        * src/fns.c (list_length, Fsafe_length, proper-list-p):
        Remove integer overflow checks that are no longer needed.

        Always set explicit HarfBuzz buffer direction

        If no direction was given by the caller, I assume the text will be drawn
        left to right, if this is not the case then callers must provide
        sensible direction. Letting HarfBuzz guess the direction is not
        appropriate since shaping and drawing must use the same direction.

        Also move hb_buffer_guess_segment_properties() call to the end, so it
        only guessing unset properties, until we completely get rid of it.

        Extend electric-layout-mode to handle more complex layouts (bug#33794)

        Entries in electric-layout-rules can specify multiple
        newline-related actions which are executed in order of appearance.

        Also, have it play nice with electric-pair-mode when inserting a
        newlines, particularly with electric-pair-open-newline-between-pairs.

        Entries in electric-layout-rules can also be functions.  Among other
        things, the logic behind electric-pair-open-newline-between-pairs
        could now be moved to electric-layout-mode, but this commit doesn't do
        that yet.

        Subclass default HarfBuzz Unicode functions

        Instead of creating new functions from scratch, subclass the default
        implementation and override the selected functions we want/can
        override.  (Bug#33729)

        Fix previous commit

2018-12-22  Khaled Hosny  <khaledhosny@eglug.org>

        Properly fix building with HarfBuzz and without libotf

        HarfBuzz support does not depend on libotf, the build breakage when
        libotf is missing was because code guarded with:

         #if defined HAVE_M17N_FLT && defined HAVE_LIBOTF

        was incorrectly changed to:

         #if defined HAVE_M17N_FLT || defined HAVE_HARFBUZZ

        this is now properly fixed by making it:

         #if (defined HAVE_M17N_FLT && defined HAVE_LIBOTF) || defined HAVE_HARFBUZZ

        Other changes in previous commits were reverted.

        Jsonrpc error handlers can now safely call jsonrpc-shutdown

        Previously, if an error handler called jsonrpc-shutdown, and if that
        error handler was being called from the process sentinel,
        jsonrpc-shutdown would infloop waiting for jsonrpc-sentinel-done to be
        set.

        Rename the process property jsonrpc-sentinel-done to
        jsonrpc-sentinel-cleanup-started, arrange for it to be set earlier
        in the sentinel, and also check for it earlier in jsonrpc-shutdown.

        * lisp/jsonrpc.el (Version): Bump to 1.0.7.
        (jsonrpc--process-sentinel): Set jsonrpc-sentinel-cleanup-started
        a bit earlier than previous jsonrpc-sentinel-done.
        (jsonrpc-shutdown): Query jsonrpc-sentinel-cleanup-started

        * lisp/net/tramp.el: Rework mutual dependencies

        Functionally split tramp-loaddefs.el into two parts: one part run
        while loading it at the very beginning of loading tramp.el (holding plain
        autoloads and declarations), and another run at the very end of loading
        tramp.el (holding setup code).
        This should reduce infinite-recursion problems while loading.

        * lisp/net/tramp.el: Require tramp-loaddefs at beginning.
        Run (new and internal) tramp--startup-hook at the end.
        Remove all tramp-autoloads.  Prefer tramp--with-startup over
        eval-after-load.
        (tramp--with-startup): New macro.
        (tramp-set-syntax): Show the new value rather than the old value in the
        error message.
        (tramp-syntax-values): Explicitly return 'values'.

        (tramp-postfix-host-format, tramp-postfix-host-regexp)
        (tramp-remote-file-name-spec-regexp, tramp-file-name-structure)
        (tramp-completion-file-name-regexp): Don't initialize in the declaration,
        since it's recomputed at the end anyway.
        (tramp-time-dont-know, tramp-time-doesnt-exist): Move before first use.

        * lisp/net/tramp-compat.el: Don't require tramp-loaddefs any more.
        (tramp-compat-tramp-syntax): Declare tramp-syntax.

        * lisp/net/tramp-smb.el:
        * lisp/net/tramp-rclone.el:
        * lisp/net/tramp-gvfs.el:
        * lisp/net/tramp-ftp.el:
        * lisp/net/tramp-adb.el: Wrap all autoloaded setup operations within
        tramp--with-startup.

        tramp--with-startup.
        (tramp-display-escape-sequence-regexp)
        (tramp-device-escape-sequence-regexp): Don't tramp-autoload any more.
        (tramp-stat-marker): Use eval-and-compile rather than tramp-autoload.

        * lisp/net/tramp-sudoedit.el: Wrap all autoloaded setup operations within
        tramp--with-startup.
        Require tramp-sh at compile-time to precompute some regexps based on
        tramp-stat-marker.

        way earlier in the startup process, when init_environment was

2018-12-06  Paul Eggert  <eggert@cs.ucla.edu>

        Fix emacsclient hang when backgrounded

        Problem reported by Kaushal Modi in:
        https://lists.gnu.org/r/emacs-devel/2018-12/msg00083.html
        The tcdrain call replaced an fdatasync call which had no
        effect on the tty, so removing it entirely shouldn’t cause
        problems.  The fdatasync call replaced an fsync call which
        also had no effect on the tty, and the fsync call seems to be
        badly-merged revenant of emacsclient’s old (circa 2004) way of
        communicating to and from Emacs via FILE * streams, where
        fsync was apparently needed when talking to sockets.
        * lib-src/emacsclient.c [!DOS_NT]: Don’t include termios.h.
        (flush_stdout): Remove.  All callers removed.
        (main): Do not drain the tty after "Waiting for Emacs..."
        message.  There should be no need to drain, and draining it
        might send us a SIGTTOU.  Do not fflush stdout just before
        exiting, as exiting does that for us.

        Convert NS face colors to RGBA when comparing with frame values

        The NS port uses indexes into a color table to specify the colors of
        faces, whereas frames use RGBA pixel values.  In
        extend_face_to_end_of_line the two needed to be compared to ensure
        that the backgrounds of certain faces are not extended to the edge of
        the window, which was failing because of this difference, thus causing
        a visual difference with other platforms.  Convert from index to RGBA
        when doing such comparisons.

        * src/dispextern.h (FACE_COLOR_TO_PIXEL) [HAVE_NS]: New macro.  Call
        ns_color_index_to_rgba under NS only.

        * src/nsgui.h: Add prototype for ns_color_index_to_rgba.

        * src/nsterm.m (ns_color_index_to_rgba): New function.  Converts a
        color_table entry to corresponding RGBA pixel value.

        * src/xdisp.c (extend_face_to_end_of_line): Call FACE_COLOR_TO_PIXEL
        on face background color when comparing with frame color.

        Make compilation mode work with warnings from compiled buffer functions

        In particular, warning messages from compile_defun now contain the source
        buffer name and line and column numbers.  Typing CR on such a warning now
        moves to the pertinent place in the source buffer.

        This fixes bug #33475

        * lisp/emacs-lisp/bytecomp.el (top-level): Require compile.elc?.
        (emacs-lisp-compilation-file-name-or-buffer)
        (emacs-lisp-compilation-parse-errors-filename-function): New
        variables/constants.
        (emacs-lisp-compilation-mode): New mode derived from compilation-mode.
        (byte-compile-log-file): Check byte-compile-current-file for being a string,
        not merely non-nil.  Change wording in message from "buffer" to "in buffer".
        Go into emacs-lisp-compilation-mode rather than the plain compilation-mode.
        (compile-defun): Bind byte-compile-current-file to current-buffer, not nil.

        * lisp/progmodes/compile.el
        (compilation-parse-errors-filename-function): Amend comments to specify that
        this function may return a buffer, and that it need not save the match data.
        (Several places): Amend comments to allow for the use of a buffer rather than
        a file name.
        (compilation-next-error-function): If the "file name" in file struct is
        actually a buffer, use it rather than compilation-find-file's result.
        (compilation-get-file-structure): save-match-data around the call to
        compilation-parse-errors-filename-function.  Only call
        command-line-normalize-file-name when `filename' is a string.

        Unbreak compilation of emacsclient on MS-Windows

        * lib-src/emacsclient.c (main): Make "-suspend" handling
        conditional on !WINDOWSNT, as there's no SIGSTOP nor 'kill'
        there.

2018-11-26  Paul Eggert  <eggert@cs.ucla.edu>

        emacsclient: assume HAVE_INET_SOCKETS

        * configure.ac (HAVE_INET_SOCKETS): Remove.
        * lib-src/emacsclient.c: Simplify by assuming HAVE_SOCKETS and
        HAVE_INET_SOCKETS, which are always true nowadays, except perhaps
        for MS-DOS and if so this program shouldn’t be built there anyway.
        Don’t bother including sys/types.h, as it’s not needed on modern
        systems (and syswait.h does it for us anyway).
        (main): Simplify by assuming SIGSTOP (which is always defined
        if SIGCONT is), and by assuming HAVE_SOCKETS && HAVE_INET_SOCKETS.

        emacsclient: negate NO_SOCKETS_IN_FILE_SYSTEM

        * lib-src/emacsclient.c (SOCKETS_IN_FILE_SYSTEM): Rename from
        NO_SOCKETS_IN_FILE_SYSTEM, with inverted sense.  All uses changed.
        All uses were of the form ‘#ifndef NO_SOCKETS_IN_FILE_SYSTEM’, and
        it’s easier to read ‘#ifdef SOCKETS_IN_FILE_SYSTEM’.

        emacsclient: fix some races on POSIX systems

        Fix some longstanding race conditions due to emacsclient’s use of
        ‘signal’ instead of ‘sigaction’ and its use of nested signal
        handlers.  These races could cause premature exit or incorrect
        commands sent to Emacs.
        * lib-src/emacsclient.c (signal) [!WINDOWSNT]: Do not undef.
        (emacs_socket): Remove this static variable.  It is now a parameter.
        (send_to_emacs): Do not exit merely because ‘send’ was interrupted.
        Instead, act on the signal if possible, and then retry the ‘send’.
        (pass_signal_to_emacs): Remove; now done by act_on_signals.
        (reinstall_handler_if_needed, handle_sigttou, handle_sigwinch)
        (install_handler): New functions.
        (got_sigcont, got_sigtstp, got_sigttou, got_sigwinch):
        New globals, used for more-portable signal handling.
        (handle_sigcont, handle_sigtstp): Just set the static var; other
        actions are now done later by act_on_signals.
        (install_handler): New function that arranges for signals to
        never be reset to default, on modern POSIX platforms.
        This fixes some races.
        (act_on_signals): New function.  When acting on SIGCONT,
        don’t bother calling getpgrp if tcgetpgrp fails.
        (start_daemon_and_retry_set_socket): Return the socket
        rather than setting a global variable.  All uses changed.
        (flush_stdout): New function that acts on signals received while
        flushing.
        (main): Use it.  emacs_socket is now a local var.
        Act on signals received during recv.

        bug1253. Reported by David Rogoff.

        not including nested array references, msg2417.
        (verilog-at-constraint-p): begin/end are illegal inside constraint blocks,
        so use that knowledge to make smarter indentation decisions.
        (verilog-auto-simplify-expressions, verilog-simplify-range-expression):
        Add `verilog-auto-simplify-expressions' to disable range simplifications.
        (verilog-auto-save-check, verilog-batch-execute-func): Fix .* causing
        Emacs batch to always re-save files with no changes, bug1239.  Reported by

        Fix interaction between vc-hg find-file-hook and vc state caching

        Bad assumptions in the `vc-hg-find-file-hook' prevented it from
        working. This correctly them.  (Bug#33129).

        2018-10-23  Daniel Pittman  <slippycheeze@google.com>

                * lisp/vc/vc-hg.el (vc-hg-find-file-hook): This function made two
                assumptions about conflicted files that were not accurate,
                preventing conflicts in files ever being detected.

                The first was that the `vc-state' was cache by the time this was
                invoked, which it is not - at least when visiting the file, or
                using `vc-refresh-state'.

                The second was that a file with the ".orig" extension would be
                present, next to the file being visited.  This is the default
                behavior of Mercurial, but can be overridden by the user.

                Since the VC mode-line code will shortly calculate the state for
                display, the optimization of testing for the ".orig" file only
                delayed this work by a few moments.

        Although the previously-applied fix worked for its platform,
        it doesn’t suffice in general.
        * src/bytecode.c (exec_byte_code): Save VECTOR into stack slot
        so that it survives GC.  The stack slot was otherwise unused,

        2018-10-14T19:12:04Z!gazally@runbox.com.  Adding ‘volatile’
        does not suffice, since storage for a volatile local can be
        reclaimed after its last access (e.g., by tail recursion

        Add support in emacsclient for EMACS_SOCKET_NAME

        If the '--socket-name' argument is unspecified, the environment
        variable 'EMACS_SOCKET_NAME' is now consulted with the same
        semantics.  This mirrors the behavior of the '--server-file' argument,
        and allows for easier configuration of emacsclient when the socket is
        in a location other than 'TMPDIR' or '/tmp'.

        * emacsclient.c (set_socket): Add support for the
        EMACS_SOCKET_NAME environment variable.  (Bug#33095)

        In edebug in GUIs, move focus to the selected frame.

        Thus when entering edebug, the focus will be moved to the frame with the
        source being debugged, and when its finished, the focus will move back.
        Commands edebug-visit-eval-list (`E') and edebug-bounce-point (`p') have been
        likewise amended.

        * src/keyboard.c (readable_events): Handle FOCUS_OUT_EVENT as an invisible
        event.  This prevents input-pending-p returning t when one of these events
        arrives, and thus obviates an instant termination of sit-for when there's no
        "real" event waiting.

        * lisp/emacs-lisp/edebug.el (edebug-focus-frame): New function.
        (edebug-default-enter, edebug--display-1, edbug-where, edebug-bounce-point)
        (edebug-visit-eval-list): Call edebug-focus-frame to move focus into the
        window newly selected by edebug-pop-to-buffer.

        Fix struct thread alignment on FreeBSD x86

        Problem reported by Joseph Mingrone in:
        https://lists.gnu.org/r/emacs-devel/2018-10/msg00238.html
        While we’re at it, apply a similar fix to struct Lisp_Subr; this
        removes the need for GCALIGNED_STRUCT_MEMBER and thus can shrink
        struct Lisp_Subr a bit.
        * configure.ac (HAVE_STRUCT_ATTRIBUTE_ALIGNED): Bring back this macro.
        Although used only for performance (not to actually align
        structures), we might as well take advantage of it.
        * src/lisp.h (GCALIGNED_STRUCT_MEMBER): Remove; all uses removed.
        (union Aligned_Lisp_Subr): New type, like struct Lisp_Subr but aligned.
        * src/lisp.h (XSUBR, DEFUN):
        * src/lread.c (defsubr): Use it.  All callers changed.
        * src/thread.c (union aligned_thread_state): New type.
        (main_thread): Now of this type, so it’s aligned.
        All uses changed.
        * src/xmenu.c (syms_of_xmenu) [USE_GTK || USE_X_TOOLKIT]:
        Adjust to union Aligned_Lisp_Subr change.

        (follow-prev-buffer): New variable.
        (follow-adjust-window): Manipulate cursor-in-non-selected-windows when the

        Rework empty abbrev table omitting

        There were two problems with the original implementation:

        1. It changed the behavior of insert-abbrev-table-description when
        READABLE is nil to sometimes insert one Emacs Lisp expression and
        sometimes insert nothing.
        2. It broke the tests.

        This commit reworks this so that insert-abbrev-table-description
        always inserts an expressions even if no abbrevs need to be saved and
        making only write-abbrev-file check that a table has any abbrevs to
        save before calling insert-abbrev-table-description.  This duplicates
        the work of filtering the table for saveable abbrevs, but the benefit
        of keeping the API is worth it.

        * doc/lispref/abbrevs.texi (Abbrev Tables): Update documentation.
        * lisp/abbrev.el (write-abbrev-file): Skip tables without user abbrevs
        (insert-abbrev-table-description): Always insert the define
        expression.
        (abbrev--table-symbols): New function.
        * test/lisp/abbrev-tests.el (abbrev--table-symbols-test):
        Add test for abbrev--table-symbols.

        Fix mishandling of symbols that look like numbers

        * src/bignum.c (make_neg_biguint): New function.
        * src/lread.c (read1): Do not mishandle an unquoted symbol
        with name equal to something like "1\0x", i.e., a string
        of numeric form followed by a NUL byte.
        Formerly these symbols were misread as numbers.
        (string_to_number): Change last argument from an integer flag
        to a pointer to the length.  This lets the caller figure out
        how much of the prefix was used.  All callers changed.
        Add a fast path if the integer (sans sign) fits in uintmax_t.
        Update comments and simplify now that bignums are present.
        * src/print.c (print_object): Fix quoting of symbols that look
        like numbers, by relying on string_to_number for the tricky
        cases rather than trying to redo its logic, incorrectly.  For
        example, (read (prin1-to-string '\1e+NaN)) formerly returned
        "1e+NaN", which was wrong: a backslash is needed in the output
        to prevent it from being read as a NaN.  Escape NO_BREAK_SPACE
        too, since lread.c treats it like SPACE.
        * test/src/print-tests.el (print-read-roundtrip):
        Add tests illustrating the abovementioned bugs.

        Fix malfunctioning cursor display on 32-bit Gtk

        This bug on 32-bit platforms was caused by the timespec_hz
        definition going haywire because the C expression
        FIXNUM_OVERFLOW_P (MOST_POSITIVE_FIXNUM) did not work in #if.
        Eventually the numeric problem showed up as a malfunctioning
        cursor (Bug#32992).  Fix the problem with MOST_POSITIVE_FIXNUM.
        By the way, make_fixnum should check for integer overflow when
        debugging; this would have made it easier to track this bug down.
        But one fix at a time.
        * src/lisp.h (INTTYPEBITS): Now a macro, so usable in #if.
        (MOST_POSITIVE_FIXNUM): Mention it’s used in #if.

        Ibuffer filter by modes: Accept several mode names

        Extend all mode filters so that they handle >1 mode.
        For instance, if the users want to filter all buffers in
        C or C++ mode, then they can call the filter interactively
        with input: 'c-mode,c++-mode' (Bug#32731).

        * lisp/ibuf-macs.el(define-ibuffer-filter): Add key :accept-list.
        If the value of this key is non-nil, then the filter accepts
        either a single qualifier or a list of them; in the latter case,
        the resultant filter is the `or' composition of the individual ones.

        * lisp/ibuf-ext.el (ibuffer-filter-by-used-mode)
        (ibuffer-filter-by-mode, ibuffer-filter-by-derived-mode)
        Set :accept-list value non-nil.
        Interactively, accept a comma separated list of mode names.

        Avoid writing empty abbrev tables

        Fixes bug#29923

        'insert-abbrev-table-description' with a non-nil READABLE inserts Lisp
        forms suitable for evaluation to restore the defined abbrevs.  We
        don't have to insert a form for tables that do not have any abbrevs.

        To implement this, we need to filter out system abbrevs before
        checking if a table is empty, because system abbrevs were previously
        skipped in the 'abbrev--write' call, at which point we would already
        have started inserting the beginning of a table definition form.

        * lisp/abbrev.el (insert-abbrev-table-description):
        Skip inserting empty tables when READABLE is non-nil.
        Clarify behavior in documentation string.
        (abbrev--write): Remove system abbrev check.

        * doc/lispref/abbrevs.texi (Abbrev Tables): Document behavior
        with empty tables.

        Remove some assumptions about timestamp format

        These changes remove some assumptions of Lisp code on timestamp
        format.  Although we’re not going to change the default format any
        time soon, I went looking for code that was too intimate about
        details of timestamp format and removed assumptions where this was
        easy to do with current Emacs primitives.
        * lisp/ido.el (ido-wash-history):
        Fix test for zero timestamp.
        * lisp/time.el (display-time-event-handler):
        Use time-less-p rather than doing it by hand.
        (display-time-update): Simplify by using float-time
        instead of doing the equivalent by hand.

        file-attributes cleanup

        Mostly, this replaces magic-number calls like (nth 4 A) with
        more-informative calls like (file-attribute-access-time A).
        It also fixes some documentation and minor timestamp coding

        * lisp/multifile.el: New file, extracted from etags.el

        The main motivation for this change was the introduction of
        project-query-replace.  dired's multi-file query&replace was implemented
        on top of etags.el even though it did not use TAGS in any way, so I moved
        this generic multifile code into its own package, with a nicer interface,
        and then used that in project.el.

        * lisp/progmodes/project.el (project-files): New generic function.
        (project-search, project-query-replace): New commands.

        * lisp/dired-aux.el (dired-do-search, dired-do-query-replace-regexp):
        Use multifile.el instead of etags.el.

        * lisp/progmodes/etags.el: Remove redundant :groups.
        (next-file-list): Remove var.
        (tags-loop-revert-buffers): Make it an obsolete alias.
        (next-file): Don't autoload (it can't do anything useful before some
        other etags.el function setup the multifile operation).
        (tags--all-files): New function, extracted from next-file.
        (tags-next-file): Rename from next-file.
        Rewrite using tags--all-files and multifile-next-file.
        (next-file): Keep it as an obsolete alias.
        (tags-loop-operate, tags-loop-scan): Mark as obsolete.
        (tags--compat-files, tags--compat-initialize): New function.
        (tags-loop-continue): Rewrite using multifile-continue.  Mark as obsolete.
        (tags--last-search-operate-function): New var.
        (tags-search, tags-query-replace): Rewrite using multifile.el.

        * lisp/emacs-lisp/generator.el (iter-end-of-sequence): Use 'define-error'.
        (iter-make): New macro.
        (iter-empty): New iterator.

        * lisp/menu-bar.el (menu-bar-search-menu, menu-bar-replace-menu):
        tags-loop-continue -> multifile-continue.

        Fix ambiguity in nil DST flag

        Formerly nil meant both that DST was not in effect and that
        the DST flag was unknown, and different functions interpreted
        the flag differently.  Now the meaning is consistently nil for
        DST not in effect, and -1 for DST flag not known.
        * doc/lispref/os.texi (Time Conversion): The DST slot is
        now three-valued, not two-.
        * doc/misc/emacs-mime.texi (time-date): Adjust to new behavior.
        * etc/NEWS: Mention this.
        * lisp/calendar/parse-time.el (parse-time-string):
        * src/editfns.c (Fdecode_time):

        * test/lisp/calendar/parse-time-tests.el (parse-time-tests):
        Adjust tests to match new behavior, and add a new
        test for nil vs -1.

        Bindat examples in source, not manual

        * doc/lispref/processes.texi (Bindat Examples): Remove, fixing
        a FIXME in the manual.  The long example had bitrotted to some
        extent, compared to the more-up-to-date example in bindat.el
        commentary, which apparently what people were referring to
        anyway.  The short example was confusing and not that useful
        and will be obsolescent anyway if we change timestamp format.

        Move current_timespec decl to timespec.h

        This change was motivated by the desire to remove the weird
        dependency of lib-src/profile.o on src/systime.h.  profile.c
        included systime.h only for current_timespec, and this
        inclusion required systime.h to have #ifdef emacs in multiple
        places and complicated further changes I have in mind.
        The current_timespec decl belongs in timespec.h anyway,
        and the main effect of this change is to move it there.
        * lib-src/profile.c (INLINE): Remove.
        Include timespec.h, not systime.h.
        * lib/gettime.c (gettime): Prefer clock_gettime to nanotime,
        and don’t worry about it failing on a CLOCK_REALTIME arg.
        POSIX requires it to succeed and I don’t know of any
        counterexamples where the fallbacks would work.
        (current_timespec): Move here from src/systime.h.
        Nowadays it seems to be better to not have this function
        be inline.
        * lib/timespec.h: Include arg-nonnull.h.
        (current_timespec): New declaration.
        (gettime, settime): Declare args to be nonnull.
        * lib/gettime.c, lib/timespec.h: Copy from Gnulib.
        * src/systime.h: Simplify by assuming ‘emacs’ is defined,
        which it always is now.
        (current_timespec): Move to lib/timespec.h.

2018-09-16  Stefan Monnier  <monnier@iro.umontreal.ca>

        * lisp/delsel.el (minibuffer-keyboard-quit): Remove old redundant code.

        The various minibuffer maps all inherit from minibuffer-local-map nowadays,
        so a single binding in it is all it takes.

        itimerspec works.  POSIX no longer requires support for the
        obsolescent setitimer function.

        * lisp/mh-e/mh-junk.el (mh-junk-process-blacklist, mh-junk-process-whitelist): Do
        not call mh-next-msg.  Now that these functions are called from
        mh-execute-commands, they should not change the current message pointer.
        The calls to mh-next-msg are probably left over from when blacklist and
        whitelist message processing was done immediately.

        Tweak nthcdr for bignum efficiency

        * src/fns.c (Fnthcdr): Use mpz_tdiv_ui and mpz_tdiv_r
        instead of mpz_mod_ui and mpz_mod, as they are more efficient.
        Suggested by Pip Cet in:

        Speed up (+ 2 2) by a factor of 10

        Improve arithmetic performance by avoiding bignums until needed.
        Also, simplify bignum memory management, fixing some unlikely leaks.
        This patch improved the performance of (+ 2 2) by a factor of ten
        on a simple microbenchmark computing (+ x 2), byte-compiled,
        with x a local variable initialized to 2 via means the byte
        compiler could not predict: performance improved from 135 to 13 ns.
        The platform was Fedora 28 x86-64, AMD Phenom II X4 910e.
        Performance also improved 0.6% on ‘make compile-always’.
        * src/bignum.c (init_bignum_once): New function.
        * src/emacs.c (main): Use it.
        * src/bignum.c (mpz): New global var.

        temporaries.
        * src/bignum.h (bignum_integer): New function.
        * src/data.c (Frem, Fmod, Fash, expt_integer):

        in intmax_t instead of mpz_t, when they fit.
        Break out mpz_t calculations into bignum_arith_driver.
        (Fquo): Use floatop_arith_driver instead of float_arith_driver,
        since the op is known to be valid.
        (Flogcount, Fash): Simplify by coalescing bignum and fixnum code.
        (Fadd1, Fsub1): Simplify by using make_int.

        Make todo-show work when adding and deleting a new todo file

        * lisp/calendar/todo-mode.el (todo-add-file): Since
        todo-current-todo-file must be set before calling todo-show, but
        the buffer is not yet in todo-mode, which makes it buffer local,
        explicitly set it buffer locally (bug#32627).

        Rename Emacs-specific INFINITY constants

        Although these constants were not erroneous, as they were
        used only in modules that did not include <math.h>, it's
        less confusing to names that cannot be confused with
        the now-standard INFINITY macro.
        * src/dispextern.h (SCROLL_INFINITY): New constant.
        * src/dispnew.c, src/scroll.c (INFINITY):
        Remove.  All uses replaced with SCROLL_INFINITY.

        Port better to non-IEEE platforms

        * src/lread.c (string_to_number) [!IEEE_FLOATING_POINT]:
        Do not use the INFINITY macro, since the C standard requires

        support infinities.

        Several fixes for formatting bignums

        * src/bignum.c: Include stdlib.h, for abs.
        (bignum_bufsize, bignum_to_c_string): New functions.
        * src/bignum.c (bignum_to_string):
        * src/print.c (print_vectorlike): Use them.
        * src/editfns.c (styled_format): Instead of having a separate
        buffer for sprintf (which does not work for bignums), just append
        to the main buffer.  When formatting bignums, add support for the
        standard integer flags -, #, 0, + and space.  Fix some comments.
        Capitalize properly when formatting bignums with %X.  Use
        functions like c_isdigit rather than reinventing the wheel.
        Simplify computation of excess precision.
        * src/print.c: Do not include bignum.h; no longer needed.
        (print_vectorlike): Avoid recalculating string length.
        * test/src/editfns-tests.el (format-bignum):
        Test some of the above fixes.

        Improve (format "%g" bignum) precision

        * src/editfns.c (styled_format): When formatting bignums with
        floating-point conversions like %g, use long double if that
        would lose less information than double, which is what the
        code was already doing for fixnums.  On Fedora 28 x86-64, for
        example, (format "%.100g" (1- (ash 1 64))) now yields
        "18446744073709551615" instead of the numerically incorrect
        "18446744073709549568".  Also, fix a stray INTEGERP that
        can just be FIXNUMP, since bignums are not possible there.

        Improve bignum support for system types

        Use bignums when Emacs converts to and from system types like
        off_t for file sizes whose values can exceed fixnum range.
        Formerly, Emacs sometimes generted floats and sometimes ad-hoc
        conses of integers.  Emacs still accepts floats and conses for
        these system types, in case some stray Lisp code is generating
        them, though this usage is obsolescent.

        Optimization opportunity noted by Pip Cet in:
        https://lists.gnu.org/r/emacs-devel/2018-08/msg00828.html
        On my platform (Fedora 28 x86-64, AMD Phenom II X4 910e,

        The change from 2017-12-22 "Support French password prompts in shell"
        tried to allow nonbreaking space in addition to whitespace syntax
        characters around the colon, but used square brackets which cause "\s"
        to be interpreted literally rather than as a backslash construct.
        * lisp/comint.el (comint-password-prompt-regexp): Use [[:blank:]]
        instead, which also has the benefit of not relying on the major mode's
        whitespace syntax setting.

        I looked through all instances of most-negative-fixnum
        and most-positive-fixnum in the Lisp source code, and
        when it was easy I removed assumptions that integers

        Fix bugs when rounding to bignums

        Also, since Emacs historically reported a range error when
        rounding operations overflowed, do that consistently for all
        bignum overflows.
        * doc/lispref/errors.texi (Standard Errors):
        * doc/lispref/numbers.texi (Integer Basics): Document range errors.
        * src/alloc.c (range_error): Rename from integer_overflow.
        All uses changed.
        * src/floatfns.c (rounding_driver): When the result of a floating
        point rounding operation does not fit into a fixnum, put it
        into a bignum instead of always signaling an range error.
        * test/src/floatfns-tests.el (divide-extreme-sign):
        These tests now return the mathematically-correct answer
        instead of signaling an error.
        (bignum-round): Check that integers round to themselves.

        Audit use of lsh and fix glitches

        I audited use of lsh in the Lisp source code, and fixed the
        glitches that I found.  While I was at it, I replaced uses of lsh
        with ash when either will do.  Replacement is OK when either
        argument is known to be nonnegative, or when only the low-order
        bits of the result matter, and is a (minor) win since ash is a bit
        more solid than lsh nowadays, and is a bit faster.
        * lisp/calc/calc-ext.el (math-check-fixnum):
        Prefer most-positive-fixnum to (lsh -1 -1).
        * lisp/vc/vc-hg.el (vc-hg-state-fast): When testing fixnum width,
        prefer (zerop (ash most-positive-fixnum -32)) to (zerop (lsh -1
        32)) (Bug#32485#11).
        * lisp/emacs-lisp/bytecomp.el (byte-compile-lapcode):
        Tighten sanity-check for bytecode overflow, by checking that the
        result of (ash pc -8) is nonnegative.  Formerly this check was not
        needed since lsh was used and the number overflowed differently.

        Avoid libgmp aborts by imposing limits

        libgmp calls ‘abort’ when given numbers too big for its
        internal data structures.  The numeric limit is large and
        platform-dependent; with 64-bit GMP 6.1.2 it is around
        2**2**37.  Work around the problem by refusing to call libgmp
        functions with arguments that would cause an abort.  With luck
        libgmp will have a better way to do this in the future.
        Also, introduce a variable integer-width that lets the user
        control how large bignums can be.  This currently defaults
        to 2**16, i.e., it allows bignums up to 2**2**16.  This
        should be enough for ordinary computation, and should
        help Emacs to avoid thrashing or hanging.
        Problem noted by Pip Cet (Bug#32463#71).
        * doc/lispref/numbers.texi, etc/NEWS:
        Document recent bignum changes, including this one.
        Improve documentation for bitwise operations, in the light

        Problem and initial solution reported by Andy Moreton in:
        https://lists.gnu.org/r/emacs-devel/2018-08/msg00503.html
        * doc/lispref/numbers.texi (Math Functions): expt integer
        overflow no longer causes truncation; it now signals an error
        since bignum overflow is a big deal.
        * src/floatfns.c (Fexpt): Support bignum arguments.
        * test/src/floatfns-tests.el (bignum-expt): New test.

        Tweak integer division

        * src/data.c (arith_driver): Reorder to remove unnecessary

        fixnum to mpz_t.  Simplify.

2018-08-18  Paul Eggert  <eggert@cs.ucla.edu>

        Simplify float_arith_driver

        * src/data.c (float_arith_driver): Simplify, as we needn’t

2018-08-18  Paul Eggert  <eggert@cs.ucla.edu>

        Minor fixups for intmax_t→mpz_t conversion

        * src/alloc.c (mpz_set_intmax_slow): Tighten assertion.
        Work even in the unlikely case where libgmp uses nails.
        * src/data.c (FIXNUMS_FIT_IN_LONG): New constant.
        (arith_driver): Use it to tighten compile-time checks.
        * src/lisp.h (mpz_set_intmax): Do not assume that converting
        an out-of-range value to ‘long’ is harmless, as it might raise
        a signal.  Use simpler expression; compiler can optimize.

2018-08-18  Paul Eggert  <eggert@cs.ucla.edu>

        Improve --with-wide-int mpz_t→fixnum conversion

        These tuneups and minor simplifications should affect only
        platforms with EMACS_INT wider than ‘long’.
        * src/alloc.c (make_number): If the number fits in long but
        not in fixnum, do not attempt to convert to fixnum again.
        Tighten the compile-time check for whether the second attempt
        is worth trying, from sizeof (long) < sizeof (EMACS_INT) to
        LONG_WIDTH < FIXNUM_BITS.  Do not bother computing the sign of
        the value to tighten the bounds for whether to try the second
        attempt, as it’s not worth the effort.  Do not call mpz_size,
        which is unnecessary since the number of bits is already known
        and the loop can iterate over a shift count instead.  Avoid
        unnecessary casts.  Use + instead of | where either will do,
        as + is typically better for optimization.

        Improve mpz_t to fixnum when --with-wide-int
        * src/alloc.c (make_number): Avoid undefined behavior
        when shifting an EMACS_UINT by more than EMACS_UINT_WIDTH bits.
        Check for integer overflow when shifting.

        Improve bignum comparison (Bug#32463#50)

        * src/data.c (isnan): Remove, as we can assume C99.
        (bignumcompare): Remove, folding its functionality
        into arithcompare.
        (arithcompare): Compare bignums directly here.
        Fix bugs when comparing NaNs to bignums.
        When comparing a bignum to a fixnum, just look at the
        bignum’s sign, as that’s all that is needed.
        Decrease scope of locals when this is easy.
        * test/src/data-tests.el (data-tests-bignum): Test bignum vs NaN.

        Restore traditional lsh behavior on fixnums

        * doc/lispref/numbers.texi (Bitwise Operations): Document that
        the traditional (lsh A B) behavior is for fixnums, and that it
        is an error if A and B are both negative and A is a bignum.
        See Bug#32463.
        * lisp/subr.el (lsh): New function, moved here from src/data.c.
        * src/data.c (ash_lsh_impl): Remove, moving body into Fash
        since it’s the only caller now.
        (Fash): Check for out-of-range counts.  If COUNT is zero,
        return first argument instead of going through libgmp.  Omit
        lsh code since lsh is now done in Lisp.  Add code for shifting
        fixnums right, to avoid a round trip through libgmp.
        (Flsh): Remove; moved to lisp/subr.el.
        * test/lisp/international/ccl-tests.el (shift):
        Test for traditional lsh behavior, instead of assuming
        lsh is like ash when bignums are present.
        * test/src/data-tests.el (data-tests-logand)
        (data-tests-logior, data-tests-logxor, data-tests-ash-lsh):
        New tests.

        Port better to x86 -fexcess-precision=fast

        Problem reported by Eli Zaretskii in:
        https://lists.gnu.org/r/emacs-devel/2018-08/msg00380.html
        * src/data.c (arithcompare): Work around incompatibility
        between gcc -fexcess-precision=fast and the C standard on x86,
        by capturing the results of floating-point comparisons before
        the excess precision spontaneously decays.  Although this fix
        might not work in general, it does work here and is probably
        good enough for the platforms we care about.

        This reverts commit c580443325a3d071625185876a8f28e04793c625.  It
        leads to situations where the sentinel hasn't run yet, which brings

2018-08-11  Paul Eggert  <eggert@cs.ucla.edu>

        Turn misc objects into pseudovectors

        Eliminate the category of miscellaneous objects, and turn all
        such objects into pseudovectors.  The immediate motivation
        for this change is to free up an enum Lisp_Type tag value, a
        scarce resource that can be better used elsewhere.  However,
        this change is worthwhile in its own right, as it improves
        performance slightly on my platform, 0.3% faster for 'make
        compile-always' on Fedora 28, and it simplifies the garbage
        collector and interpreter (Bug#32405).

        (VBLOCK_BYTES_MIN, VBLOCK_BYTES_MAX, VECTOR_MAX_FREE_LIST_INDEX):
        Prefer enums to macros where either will do.
        (allocate_vector_from_block): Arg is ptrdiff_t, not size_t.
        Use eassume instead of eassert.
        (PSEUDOVEC_STRUCT): New macro, which verifies the already-existing
        assumption that the vector-like objects are small.
        (cleanup_vector): Use it.  Use if-then-else systematically;
        this lets GCC do a bit better job.

        2018-08-08  Paul Eggert  <eggert@cs.ucla.edu>

        * src/alloc.c (VBLOCK_BYTES_MAX): Use vroundup_ct, not
        vroundup, so that can be used in static assertions.

        (tramp-archive-test44-auto-load)

        because they run longer than 10 seconds.  (Bug#30807)

        Use Gnulib regex for lib-src

        Emacs regular expressions forked from everyone else long ago.
        This makes it official and should allow simplification later.
        etags.c now uses the glibc regex API, falling back on a
        Gnulib-supplied substitute lib/regex.c if necessary.
        Emacs proper now uses its own regular expression module.
        Although this patch may look dauntingly large, most of it
        was generated automatically by admin/merge-gnulib
        and contains an exact copy of the glibc regex source,
        and the by-hand changes do not grow the Emacs source code.
        * admin/merge-gnulib (GNULIB_MODULES): Add regex.
        (AVOIDED_MODULES): Add btowc, langinfo, lock, mbrtowc, mbsinit,
        nl_langinfo, wchar, wcrtomb, wctype-h.
        * lib-src/Makefile.in (regex-emacs.o): Remove; Gnulib does it now.
        (etags_deps, etags_libs): Remove regex-emacs.o.
        * lib-src/etags.c: Go back to including regex.h.
        (add_regex): Use unsigned char translation array,
        since glibc regex requires that.
        * lib/Makefile.in (not_emacs_OBJECTS, for_emacs_OBJECTS): New macros.
        (libegnu_a_OBJECTS): Use them, to avoid building e-regex.o.
        * lib/gnulib.mk.in, m4/gnulib-comp.m4: Regenerate.
        * lib/regcomp.c, lib/regex.c, lib/regex.h, lib/regex_internal.c:
        * lib/regex_internal.h, lib/regexec.c, m4/builtin-expect.m4:
        * m4/eealloc.m4, m4/glibc21.m4, m4/mbstate_t.m4, m4/regex.m4:
        New files, copied from Gnulib.
        * src/regex-emacs.h, src/conf_post.h:
        (RE_TRANSLATE_TYPE, RE_TRANSLATE, RE_TRANSLATE_P):
        Move from src/conf_post.h to src/regex-emacs.h,
        so that they don’t interfere with compiling lib/regex.c.

2018-08-05  Paul Eggert  <eggert@cs.ucla.edu>

        Prefer ?* to hide passwords

        It might be argued that a hidden string is more legible when using
        ?* as the hidden character instead of ?.
        For example, the following strings have the same length:
        "......"

        "******"

        %o and %x can now format signed integers

        Optionally treat integers as signed numbers with %o
        and %x format specifiers, instead of treating them as
        a machine-dependent two’s complement representation.
        This option is more machine-independent, allows formats
        like "#x%x" to be useful for reading later, and is
        better-insulated for future changes involving bignums.
        Setting the new variable ‘binary-as-unsigned’ to nil
        enables the new behavior (Bug#32252).
        This is a simplified version of the change proposed in:
        https://lists.gnu.org/r/emacs-devel/2018-07/msg00763.html
        I simplified that proposal by omitting bitwidth modifiers, as
        I could not find an any example uses in the Emacs source code
        that needed them and doing them correctly would have been
        quite a bit more work for apparently little benefit.
        * doc/lispref/strings.texi (Formatting Strings):
        Document that %x and %o format negative integers in a
        platform-dependent way.  Also, document how to format

        * etc/NEWS: Document the change.
        * src/editfns.c (styled_format): Treat integers as signed
        numbers even with %o and %x, if binary-as-unsigned is nil.

        Notify systemd in daemon-initialized and kill-emacs (Bug#31498)

        With --[bg-]daemon and Type=forking, systemd will only consider the
        daemon to have fully started up once the original process exits, and
        will wait until then to start units depending on the Emacs service.  To
        get the same functionality with --fg-daemon, use Type=notify instead of
        Type=simple and explicitly send a readiness notification to systemd at
        the point where the forked process would in --bg-daemon mode notify its
        parent process and cause it to exit.  Similarly, notify systemd at the
        beginning of the shutdown process as well.  (Both of these calls are
        successful no-ops if emacs was not started by systemd.)

        Make ielm accept an optional buffer name param

        The ielm buffer name was hardcoded which made it hard for programs to
        interactively create ielm buffers with different names and switch to
        them (e.g. perhaps you want to have one ielm buffer for each of the
        Elisp projects you're working on).

2018-07-18  Paul Eggert  <eggert@cs.ucla.edu>

        Fix bug with eql etc. on NaNs

        Fix a bug where eql, sxhash-eql, memql, and make-hash-table
        were not consistent on NaNs.  Likewise for equal,
        sxhash-equal, member, and make-hash-table.  Some of these
        functions ignored NaN significands, whereas others treated
        them as significant.  It's more logical to treat significands
        as significant, and this typically makes eql a bit more
        efficient on floats, with just one integer comparison instead
        of one to three floating-point comparisons.
        * doc/lispref/numbers.texi (Float Basics): Document that
        NaNs are never numerically equal, but might be eql.

        the corresponding functions treat NaNs consistently.
        (sxhash_float): Simplify based on above-mentioned changes.

        * test/src/fns-tests.el (fns-tests-equality-nan): New test.

        * test/lisp/emacs-lisp/package-tests.el (package-test-signed): Stop
        using epg-check-configuration and ignore-errors, they're redundant
        because epg-find-configuration already does all that.
        * test/lisp/epg-tests.el (epg-tests-find-usable-gpg-configuration):
        Remove tracing.
        (with-epg-tests): Skip test if no gpg config is found.
        (epg-decrypt-1 epg-roundtrip-1, epg-sign-verify-1, epg-sign-verify-2)
        (epg-import-1): Don't check gpg configuration at top-level, rely on
        `with-epg-tests' instead.  Checking the gpg configuration requires a
        valid HOME (or GNUPGHOME), which is provided by `with-epg-tests'.

        Show full issuer and subject distinguished names

        CAs like Let's Encrypt do not put O and OU into the Subject's DN.
        Similarly, O and OU are often used to indicate Domain Validated or
        Organization Validation as opposed to the actual OU.

        Issuer CN often contains the issuer's server or as an indication of
        Extended Validation certificate as opposed to the actual issuer
        organization.

        The Hostname part as extracted from the Subject is also confusing, as
        in the case of a hostname mismatch, the Subject's CN, which
        `nsm-format-certificate' naively calls the Hostname, will not actually
        match the hostname in the problem preamble.

        * lisp/net/nsm.el (nsm-format-certificate): Show full DN of Issuer and
          Subject.  Remove Hostname.
          (nsm-certificate-part, nsm-parse-subject): Removed.

        * lisp/net/nsm.el (nsm-trust-local-network, nsm-should-check,
          nsm-check-tls-connection, nsm-check-plain-connection): New defcustom
          `nsm-trust-local-network' lets users customize whether NSM should
          check for TLS problems when connecting to the hosts on their local
          networks.  `nsm-should-check' determines whether
          `nsm-check-tls-connection' and `nsm-check-plain-connection' should
          perform checks.  localhost is implicitly trusted, thus checks are
          never performed there.

        * lisp/net/nsm.el (nsm-check-tls-connection): Batch all problems found
          before querying the user.

        * lisp/net/nsm.el (nsm--encryption): Renamed to `nsm-cipher-suite'.

        * lisp/net/nsm.el (nsm-fingerprint-ok-p): No longer prompt when
          certificate fingerprints mismatch.  Returns a boolean instead when
          the fingerprint of the certificate received matches the saved
          fingerprints.

        * lisp/net/nsm.el (nsm-query): Change signature.  Accepts a list of
          problems and a preformatted message instead of just a message format
          and the arguments for the message.

        * lisp/net/nsm.el (nsm-query-user): Change signature.  Accepts a
          preformatted message and the peer status of the handshake instead of
          a message format, its arguments and the certificate for the host.

        * lisp/net/nsm.el (nsm-save-host): Change signature.  Accepts a list of
          problems after the WHAT parameter.  Saves multiple fingerprints for
          the same host in case the host load balances a TLS server with more
          than one certificates signed with different keys.  Makes sure
          conditions are not removed when updating a fingerprint.

        * lisp/net/nsm.el (nsm-format-certificate): Display the TLS handshake's
          renegotiation info extension, compression level, encrypt-then-MAC
          extension, and key exchange prime bit length.

        * src/gnutls.c (gnutls-peer-status-warning-describe,
          gnutls-peer-status): Check for certificate verification problems
          introduced since GnuTLS 3.1.

        * src/gnutls.c (gnutls-peer-status): `:compression', `:encrypt-then-mac'
          and `:safe-renegotiation' are now contained in the peer status
          result return value.

        * src/lisp.h (union specbinding.unwind_array):
        Remove unused member func.  Move array after nelts, as this is
        likely to generate more efficient code in safe_free, which can

        Suppress errors from indent code, but don't suppress errors from

        electric indent "not working", the error should be reproducible by
        calling indent directly (as is the case for Bug#18764), or else it's
        from the electric indent code and will be reported normally.

        Properly ignore stderr in elisp Flymake backend

        comint-insert-previous-argument doesn't detect and ignore trailing &

        This function is invoked in shell-mode by the user, and is meant to
        emulate what M-. does in zsh and bash: it inserts an argument from a
        previous command.  Neither zsh nor bash treat a trailing & specially:
        M-. simply inserts it if it is encountered.  Emacs DID have extra
        logic to detect and discard trailing &, but this logic was buggy, and
        a && anywhere in the sequence would confuse it.  This patch simply
        removes that logic to fix the bug and to emulate zsh and bash more
        closely

        * lisp/comint.el (comint-insert-previous-argument): don't detect and
          ignore trailing &

        comint-insert-previous-argument counts args from start or from end

        This function is invoked in shell-mode by the user, and is meant to
        emulate what M-. does in zsh and bash: it inserts an argument from a
        previous command.  Without a prefix argument, it inserts the last arg
        from the previous command; with an argument INDEX, it inserts the
        INDEX-th argument.  bash counts from the start, while zsh counts from
        the end.  This patch adds a variable
        `comint-insert-previous-argument-from-end' that emulates the zsh
        behavior if non-nil.

        * lisp/comint.el (comint-arguments): can take in negative arguments to count
          from the end, same as indexing in python.
          (comint-insert-previous-argument): if

        Apply non-user themes only when asked

        Theme settings now generally aren't actually applied until a call to
        `enable-theme-, either one made explicitly or implicitly through
        `load-theme' with NO-ENABLE nil.  This change has the effect of not
        applying theme changes just because we load a lisp file containing a
        theme specification.  The previous behavior is preserved for the
        special case of the `user' theme, which is frequently used for
        ad-hoc customization.

2018-06-15  Paul Eggert  <eggert@cs.ucla.edu>

        Minor CANNOT_DUMP cleanups

        Mostly, this avoids munging executables when CANNOT_DUMP = yes,
        as the munging is needed only for unexec.
        * configure.ac (PAXCTL_dumped, PAXCTL_notdumped) [CANNOT_DUMP]:

        Remove old combreloc hack

        It has not been needed for many years and gets in the way of
        portable dumping, address sanitization, etc.  See:

        Fix a bug in Flymake handling of region-specific reports

        The backend's diagnostic list must be updated too, not just cleared.

        * lisp/progmodes/flymake.el (flymake--diag): Add overlay field.
        (flymake--highlight-line): Return created overlay.
        (flymake--handle-report): Iterate the backend's diagnostics, not
        the overlays.  Set diagnostic overlay.
        (flymake--run-backend): Don't clean diagnostic list here.
        (flymake-mode): Call delete-overlay directly.

2018-06-15  Eli Zaretskii  <eliz@gnu.org>

        Fix building --without-x and similar

        * src/keyboard.c (make_lispy_focus_out): Compile it

        Reported by Filipp Gunbin <fgunbin@fastmail.fm>.

2018-06-15  João Távora  <joaotavora@gmail.com>

        Flymake and backends exchange hints abouts changed regions

        (flymake-diagnostic-functions): Describe :region, :recent-changes
        in docstring.
        (flymake--handle-report): Accept REGION.

        Remove Lisp_Misc_Save_Value

        This type and its associated routines are no longer used.
        * src/alloc.c (voidfuncptr): Move here from src/lisp.h.

        (make_save_funcptr_ptr_obj, make_save_memory)
        (free_save_value, mark_save_value):
        Remove.
        (mark_object): Remove mention of Lisp_Misc_Save_Value.
        * src/lisp.h (Lisp_Misc_Save_Value, SAVE_SLOT_BITS)
        (SAVE_VALUE_SLOTS, SAVE_TYPE_BITS, enum Lisp_Save_Type)
        (struct Lisp_Save_Value, SAVE_VALUEP, XSAVE_VALUE)
        (save_type, XSAVE_POINTER, set_save_pointer)
        (XSAVE_FUNCPOINTER, XSAVE_INTEGER, set_save_integer)
        (XSAVE_OBJECT): Remove.

2018-06-14  Paul Eggert  <eggert@cs.ucla.edu>

        New type Lisp_Misc_Ptr

        This is a streamlined version of Lisp_Save_Value, which contains just
        a pointer, as that is all Lisp_Save_Values are used for any more.
        With the previous changes, these objects are not primarily used as
        save values, so just call them "Misc" rather than "Save".
        * src/alloc.c (make_misc_ptr): New function.
        (mark_object): Mark Lisp_Misc_Ptr too.
        * src/lisp.h (Lisp_Misc_Ptr): New constant.
        (struct Lisp_Misc_Ptr): New type.

        Use Lisp_Misc_Ptr, not Lisp_Save_Value.
        (union Lisp_Misc): Add Lisp_Misc_Ptr.
        * src/print.c (print_object): Print Lisp_Misc_Ptr.

2018-06-14  Paul Eggert  <eggert@cs.ucla.edu>

        Avoid allocating Lisp_Save_Value for arrays

        * src/alloc.c (mark_maybe_objects): New function.
        * src/eval.c (default_toplevel_binding)
        (backtrace_eval_unrewind, Fbacktrace__locals):
        Treat array unwindings like other miscellaneous pdl types.
        (record_unwind_protect_array): New function.
        (do_one_unbind): Free the array while unwinding.
        (mark_specpdl): Mark arrays directly.
        * src/lisp.h (SPECPDL_UNWIND_ARRAY): New constant.
        (union specbinding): New member unwind_array.
        (SAFE_ALLOCA_LISP_EXTRA): Use record_unwind_protect_array
        instead of make_save_memory + record_unwind_protect.

2018-06-14  Paul Eggert  <eggert@cs.ucla.edu>

        Avoid allocating Lisp_Save_Value for excursions

        * src/editfns.c (save_excursion_save): New arg PDL,
        specifying where to save the state.  All uses changed.
        (save_excursion_restore): Args are now the marker and info
        rather than a pointer to a Lisp_Save_Value containing them.
        All uses changed.
        * src/eval.c (default_toplevel_binding, Fbacktrace__locals):
        Treat excursions like other miscellaneous pdl types.
        (record_unwind_protect_excursion): Save data directly
        into the pdl rather than creating an object on the heap.
        This avoids the need to allocate and free an object.
        (do_one_unbind, backtrace_eval_unrewind):
        Unwind excursions directly.
        (mark_specpdl): Mark excursions directly.
        * src/lisp.h (SPECPDL_UNWIND_EXCURSION): New constant.
        (union specbinding): New member unwind_excursion.

2018-06-14  Paul Eggert  <eggert@cs.ucla.edu>

        Just use cons in macfont_descriptor_entity

        * src/macfont.m (macfont_descriptor_entity): Use cons instead
        of make_save_ptr_int, as this avoids the need for a special
        type and function for this one-off.

2018-06-14  Paul Eggert  <eggert@cs.ucla.edu>

        Avoid allocating a Lisp_Save_Value in ftfont.c

        * src/ftfont.c (struct ftfont_cache_data): New member face_refcount.
        (ftfont_lookup_cache): Clear it when initializing.
        Use make_mint_ptr, since this typically avoids the need to
        allocate a Lisp_Save_Value as refcount is now stored elsewhere.
        (ftfont_open2, ftfont_close): Manipulate the reference
        count in the struct, not in the save object.

2018-06-14  Paul Eggert  <eggert@cs.ucla.edu>

        Use record_unwind_protect_ptr to avoid allocation

        * src/term.c (struct tty_pop_down_menu): New type.
        (tty_pop_down_menu, tty_menu_show): Use it, along with
        record_unwind_protect_ptr, to avoid allocating a Lisp_Misc.
        * src/xmenu.c (struct pop_down_menu): New type.
        (pop_down_menu, x_menu_show): Use it, likewise.
        * src/xterm.c (x_cr_destroy, x_cr_export_frames):
        Use record_unwind_protect_pointer to avoid possibly allocating
        a Lisp_Misc.

2018-06-14  Paul Eggert  <eggert@cs.ucla.edu>

        Avoid Lisp_Misc allocation if C stack suffices

        * src/fileio.c (union read_non_regular): New type.

        (map_keymap_char_table_item, map_keymap_internal):
        Use it to avoid allocating a Lisp_Misc.

2018-06-14  Paul Eggert  <eggert@cs.ucla.edu>

        Simplify init_module_assertions

        * src/emacs-module.c (init_module_assertions): Just use NULL
        instead of allocating a dummy on the stack and then using
        eassert.  Practical platforms check for null pointer
        dereferencing nowadays, so this is good enough.

2018-06-14  Paul Eggert  <eggert@cs.ucla.edu>

        New mint_ptr representation for C pointers

        Fix pretty-printing empty objects as null

        * lisp/json.el (json-pretty-print): Force distinction between empty
          objects and null.
        (json-encode-list): Remove responsibility to print "null" as this
        value is not a list.
        (json-encode): Give higher precedence to lists so that an empty list
        is printed as an empty object, not as "null".

        * test/lisp/json-tests.el (test-json-encode): Add many tests to check
          the behavior of pretty-printing.

2018-06-13  Paul Eggert  <eggert@cs.ucla.edu>

        Remove some wrong 8-byte alignment assumptions

        Do not assume that 8-byte alignment suffices for all C objects,
        as some platforms require 16-byte alignment for some objects,
        and this will start to bite us as time goes on (e.g., if an
        Emacs module ever uses an object containing a long
        double, which requires 16-byte alignment on x86-64).
        Conversely, on !USE_LSB_TAG platforms, do not insist on
        aligning Lisp objects to a multiple of 8, as this is not
        needed for high-order tag bits.
        * src/alloc.c (LISP_ALIGNMENT, MALLOC_IS_LISP_ALIGNED):
        New constants.
        (XMALLOC_BASE_ALIGNMENT, XMALLOC_HEADER_ALIGNMENT):
        Removed.  All uses replaced by LISP_ALIGNMENT.
        (aligned_alloc, laligned, lmalloc, lrealloc, union aligned_Lisp_Misc)
        (maybe_lisp_pointer, pure_alloc):

        Pacify gcc -Wnull-dereference some more

        * src/keyboard.c (read_char): Use xevent_start in a couple
        more places where it is safe.  This is needed with

2018-06-10  Paul Eggert  <eggert@cs.ucla.edu>

        Use native alignment to access Lisp object data

        Instead of using __builtin_assume_aligned (P, GCALIGNMENT) to
        tell GCC that P has alignment 8, use (T *) P where T is the
        type of the pointed-to object, to tell GCC that P has native
        alignment.  This is simpler, matches the intent better, and
        should help simplify future improvements.  Some of these
        changes are to pacify gcc -Wnull-dereference, since GCC is
        smarter about pointers now that Emacs no longer uses
        __builtin_assume_aligned; these minor changes should improve
        code efficiency slightly.  On Fedora 28 x86-64 with default
        optimization this patch shrinks the size of the Emacs text
        segment by 0.36%.
        * src/conf_post.h (__has_builtin, __builtin_assume_aligned):
        Remove; no longer used.
        * src/dbusbind.c (XD_OBJECT_TO_DBUS_TYPE):
        Pacify -Wnull-dereference by using XCAR instead of CAR_SAFE
        and XCDR instead of CDR_SAFE when this is safe.
        * src/fileio.c (Fexpand_file_name):
        * src/font.c (clear_font_cache):

        * src/lisp.h (lisp_h_XUNTAG): Remove; XUNTAG is always a macro

        Correctly set last_nonmenu_event when replaying

        read_key_sequence can, in various circumstances, play back recorded
        events.  Make sure that we set last_nonmenu_event as if we weren't
        replaying.  Without this change, we leave last_nonmenu_event set to
        whatever it was before we started replaying, leading to spurious
        random keymap menu prompts appearing after reading terminal control
        sequences, the translation of which sometimes causes event replays.

        * src/keyboard.c:
        (grow_bool_vector): New function
        (read_key_sequence): Remember menu event history per-event.

        Improve robustness xterm event processing

        We used to treat the start of a focus-in, focus-out, and the start of
        a paste sequence as normal events bound in global-map, but this
        approach produces problems when we recognize events in the middle of
        actions that don't immediately dispatch to the command loop.

        Now we handle these events internally inside read-key, translating the
        focus events to nothing and paste-start into an xterm-paste event that
        neatly encapsulates the entire paste sequence.

        * lisp/term/xterm.el:

        Avoid unnecessary readahead early in TTY frame init

        We query some properties of the terminal early in initialization, and
        just before we do, we perform ordinary redisplay.  This redisplay can
        result in unsightly flickering if we change some aspects of the
        display immediately afterward and redisplay again.  By avoiding
        redisplay in xquery--query as long as we get timely responses from the
        terminal, we can avoid this early unwanted redisplay.

        Obsolete Flymake's flymake-diagnostic-types-alist

        That variable was an association between symbols and properties,
        effecively duplicating symbol's property lists.  It is simpler to just
        put properties on symbols.  Backward compatibility to the old variable
        has been kept.

        * doc/misc/flymake.texi (Flymake error types): Don't mention

        Correctly filter Flymake diagnostic types shown in mode-line

        Thus, if a package foo has its own types foo-error and
        foo-warning, and if the buffer has no errors, the mode-line
        will correctly show `[0 0]' (zero errors and warnings) instead
        of `[0 0 0 0]' (zero errors, zero foo-errors, zero warnings,
        zero  foo-warnings).

        * lisp/progmodes/flymake.el
        (flymake--mode-line-format): Coalesce diagnostic types based on
        the severity, not the symbol.

        Add proper Flymake support to cc-mode.el

        Except for the important detail that it doesn't make temporary files,
        the new flymake-cc backend doesn't yet behave much differently from
        the old flymake-proc-legacy-flymake, i.e. it still needs a special
        `check-syntax' Makefile target to provide the compiler and compilation
        flags.  However, the new infrastructure created should allow less
        intrusive cleverer flag guessers (yet to be written) to replace that
        mechanism.

        * lisp/progmodes/cc-mode.el (c-mode, c++-mode): Add to

        Amend c-before-change-check-unbalanced-strings to handle a quote at EOB.

        * lisp/progmodes/cc-mode.el (c-before-change-check-unbalanced-strings): Before
        going back a sexp from the \n marked with a string-fence syntax-table text

        property from the isolated quote, not the quote and the \n which otherwise
        delimit an unterminated string.  Should we encounter a double quote marked
        with a string-fence syntax-table text property at the end of the last line,
        remove that property.

2018-05-20  Alan Mackenzie  <acm@muc.de>

        Enhance CC Mode's fontification, etc., of unterminated strings.

        String delimiters, including escaped new lines, of correctly terminated
        strings are left in font-lock-string-face.  All others get
        font-lock-warning-face.  The latter get syntax-table text properties on the
        opening string delim and the "terminating EOL".

        Correct two miscellaneous bugs: the handling of text properties on Java Mode's
        generic delimiters; the handling of c-just-done-before-change.

        * lisp/progmodes/cc-defs.el (c-point): New position 'eoll "end of logical line".
        (c-characterp): New macro.

        * lisp/progmodes/cc-fonts.el (c-font-lock-invalid-string): Removed.
        (c-basic-matchers-before): Use a simple matcher in place of the form around
        c-font-lock-invalid-string.

        * lisp/progmodes/cc-langs.el (c-get-state-before-change-functions): Add
        c-before-change-check-unbalanced-strings to the value for all modes except AWK
        Mode.  Also add c-before-change-check-<>-operators to Java Mode, correcting an
        error in that mode's handling of generic delimiters.
        (c-before-font-lock-functions): Add c-after-change-re-mark-unbalanced-strings
        to the value for all modes except AWK Mode.
        (c-single-quotes-quote-strings, c-string-delims): New lang variables for
        future enhancements.
        (c-string-innards-re-alist): New lang variable.

        * lisp/progmodes/cc-mode.el (c-just-done-before-change): Do not set this
        variable when a change is the alteration of text properties.
        (c-basic-common-init): Set parse-sexp-lookup-properties (and the XEmacs
        equivalent) also for Pike Mode.
        (c-neutralize-CPP-line): No longer neutralize unbalanced quotes here.
        (c-unescaped-nls-in-string-p, c-multiline-string-start-is-being-detached)
        (c-pps-to-string-delim, c-before-change-check-unbalanced-strings)

2018-05-19  Eli Zaretskii  <eliz@gnu.org>

        Use Enriched mode in etc/HELLO to keep charset information

        This allows to encode HELLO in UTF-8, thus supporting the entire
        repertory of Unicode, while still keeping the charset info where
        that is important.  Suggested by Michael Welsh Duggan <mwd@md5i.com>.
        * lisp/textmodes/enriched.el (enriched-translations): Add
        translations for 'charset'.
        (enriched-decode-charset, enriched-handle-charset-prop): New
        functions.
        * lisp/facemenu.el (facemenu-special-menu): Add sub-menu for

        Port to GCC 8 -fsanitize=undefined

        In GCC 8, gcc -fsanitize=undefined flags the undefined behavior
        that Emacs relies on in its XPNTR and XSYMBOL low-level functions.
        Disable undefined sanitization in these functions.  Although this
        disabling doesn’t suffice if DEFINE_KEY_OPS_AS_MACROS is true, it
        works for -fsanitize=undefined -DINLINING=0, which is good enough.
        * src/alloc.c (macro_PNTR_ADD): New macro.
        (PNTR_ADD): New function and macro.
        The function disables -fsanitize=undefined.

        Fix decoding of directories when "~" includes non-ASCII chars

        * src/fileio.c (Fexpand_file_name): Don't build multibyte strings
        from unibyte non-ASCII strings when NAME and DEFAULT_DIRECTORY
        have different multibyteness, as this adds bytes to the byte
        sequence, and in some situations, e.g., when the home directory
        includes non-ASCII characters, can fail file APIs.  (Bug#30755)

        esh-opt.el: Fix improper parsing of first argument (Bug#28323)

        Examples of broken behavior:

            sudo -u root whoami
            Outputs: -u
            ls -I '*.txt' /dev/null
            Errors with: *.txt: No such file or directory

        * lisp/eshell/esh-opt.el (eshell--process-args): Refactor usage of
        args to eshell--args, as we rely on modifications from
        eshell--process-option and vice versa.  These modifications were not
        being propagated in the (if (= ai 0)) case, since popping the first
        element of a list doesn't destructively modify the underlying list
        object.

        The Flymake legacy "proc" backend, which is active by default will try
        to syntax-check foo.c/foo.cpp and many other types of files, but on
        failing to find a suitable Makefile target, will fail.  There's
        nothing wrong with that except that it used to leave behind the
        foo_flymake.c and foo_flymake.cpp auxiliary files behind, littering
        the filesystem.

        specifying it on the mode line, but shift it to the initial place

        like "(foo)" without losing focus (bug#30091).

        https://lists.gnu.org/r/emacs-devel/2018-04/msg00207.html

2018-04-17  Lars Ingebrigtsen  <larsi@gnus.org>

        Tweak shr window width computation

        * lisp/net/shr.el (shr-insert-document): The computation of the
        window width is apparently one pixel too wide for the shr line
        folding algorithm (bug#31196).

2018-04-17  Lars Ingebrigtsen  <larsi@gnus.org>

        (gnus-summary-select-article-buffer): Further point placing tweak

        * lisp/gnus/gnus-sum.el (gnus-summary-select-article-buffer):

        * lisp/gnus/gnus-art.el (gnus-article-read-summary-keys): Make `c'
        work from the article buffer (bug#31195) when no summary buffer is
        shown.

2018-04-17  Lars Ingebrigtsen  <larsi@gnus.org>

        Place point consistently in the Gnus group buffer on exit

        when exiting with `q' (and the like) from the article buffer when
        only the article buffer is displayed (bug#31195).  This is
        apparently yet another fall-out from the "preserve-visible-point-
        in-windows" patches of yesteryear...

2018-04-17  Lars Ingebrigtsen  <larsi@gnus.org>

        Reimplement `shr-next-link' and `shr-previous-link'

2018-04-16  Katsumi Yamaoka  <yamaoka@jpl.org>

        * lisp/mail/sendmail.el (mail-sendmail-undelimit-header): Work for
        the case where the mail header separator has already been deleted.

2018-04-16  Lars Ingebrigtsen  <larsi@gnus.org>

        (gnus-group-goto-group): Return correct value after previous patch

        * lisp/gnus/gnus-group.el (gnus-group-goto-group): Return the
        correct value after the previous patch.

        * lisp/gnus/gnus-group.el (gnus-group-goto-group): If we can't

        Make mail-sendmail-undelimit-header actually remove the delimiter

        * lisp/mail/sendmail.el (mail-sendmail-undelimit-header): Actually
        remove the mail header separator (bug#17488).  In all the cases
        where this is called, the separator will probably already have
        been removed, so the only thing this does is place point at the
        end of the headers.

2018-04-16  Lars Ingebrigtsen  <larsi@gnus.org>

        (semantic-symref-results-mode-map): Fix typo in previous check-in

2018-04-15  Lars Ingebrigtsen  <larsi@gnus.org>

        Use quit-buffer instead of semantic-symref-hide-buffer

        * lisp/cedet/semantic/symref/list.el
        (semantic-symref-hide-buffer): Removed (bug#15857).
        (semantic-symref-results-mode-map): Use quit-buffer instead.

2018-04-15  Lars Ingebrigtsen  <larsi@gnus.org>

        update.

2018-04-15  Lars Ingebrigtsen  <larsi@gnus.org>

        Add an undo command to url-cookie-mode

        * lisp/url/url-cookie.el (url-cookie-undo): New command and
        keystroke (bug#16650).

        into its own function.
        (url-cookie-delete): Use it to make the buffer look consistent
        after deleting a cookie.

2018-04-15  Lars Ingebrigtsen  <larsi@gnus.org>

        Make eww handle "http://a/../../../g"

        * lisp/net/eww.el (eww): Strip leading elements off URLs on the
        form "http://a/../../../g", because that's what all the other
        browsers do (bug#8622).

2018-04-15  Lars Ingebrigtsen  <larsi@gnus.org>

        Make url-cookie-write-file be more permissive

        * lisp/url/url-cookie.el (url-cookie-write-file): If

        Don't warn the user about large files if they are unreadable

        * lisp/files.el (abort-if-file-too-large): There's no point in
        warning the user about a too-large file if we're not able to read
        it (bug#29549).  Hopefully this doesn't introduce a race condition
        between this test and the `file-readable-p' test later.

2018-04-15  Lars Ingebrigtsen  <larsi@gnus.org>

        Only save the mailer choice after sending the mail

        * lisp/mail/sendmail.el (sendmail-query-once): Only save the
        mailer choice after we've sent the mail, so that if that fails,
        the user has an easy way to back out of the choice and make
        another (bug#14487).
        (sendmail-query-user-about-smtp): Return the choice; don't save it.

2018-04-15  Lars Ingebrigtsen  <larsi@gnus.org>

        (compose-mail): Give a better error message for `mail-user-agent'

        * lisp/simple.el (compose-mail): Give a better error message for
        invalid values for `mail-user-agent' (bug#17979).

2018-04-15  Lars Ingebrigtsen  <larsi@gnus.org>

        Fix typo in gnus.texi

        Revert "Make mail-extract-address-components return the user name more"

        This reverts commit 8b50ae8b2284b5652c2843a9d0d076f4f657be28.

        According to tests in bug#27656 by OGAWA Hirofumi, this patch
        led to wrong results when binding

        (dolist (addr '("Rasmus <rasmus@gmx.us>" "Rasmus <mbox@gmx.us>"))
          (dolist (ignore-single '(t nil))
            (dolist (ignore-same '(t nil))
              (let ((mail-extr-ignore-single-names ignore-single)
                    (mail-extr-ignore-realname-equals-mailbox-name ignore-same))
                (message "%s" (mail-extract-address-components addr))))))

        in combination.

        Query the user whether to increase stack depth in shr

        * lisp/net/shr.el (shr-insert-document): Bind `max-specpdl-size'
        here... (bug#30675).
        (shr-descend): So that we can increase it temporarily here if the
        user wants to.

2018-04-15  Lars Ingebrigtsen  <larsi@gnus.org>

        Minor copy edit of etc/NEWS

        * src/lread.c (openp): Add a comment before the now-obscure loop.

2018-04-15  Lars Ingebrigtsen  <larsi@gnus.org>

        Clarify menu entry in previous check-in

        * lisp/gnus/gnus-sum.el (gnus-summary-make-menu-bar): Menu bar
        entry for it.

2018-04-15  Lars Ingebrigtsen  <larsi@gnus.org>

        Add new command `gnus-summary-attach-article'

        * doc/misc/gnus.texi (Summary Message Commands): Document it.

        * lisp/gnus/gnus-msg.el (gnus-summary-attach-article): New command
        and keystroke (bug#19788).

        * lisp/gnus/gnus-sum.el (gnus-summary-make-menu-bar): Menu bar
        entry for it.

2018-04-15  Daiki Ueno  <ueno@gnu.org>

        Divert to call `gnus-activate-group' with the SCAN argument set

        * lisp/gnus/gnus-group.el (gnus-group-get-new-news-this-group):
        Divert to call `gnus-activate-group' with the SCAN argument set,
        if request-group-scan is not defined for the backend.  Ensure that
        the server is open when calling `gnus-request-group-scan'
        (bug#22649).

2018-04-15  Lars Ingebrigtsen  <larsi@gnus.org>

        Abort Gnus exit if we have unsaved Message buffers

        * lisp/gnus/gnus-group.el
        (gnus--abort-on-unsaved-message-buffers): New function (bug#28843).
        (gnus-group-exit): Use it to abort exit if we have unsaved Message
        buffers.

2018-04-15  Lars Ingebrigtsen  <larsi@gnus.org>

        Avoid an infloop in shr filling when not using fonts

        * lisp/net/shr.el (shr-fill-line): If we have an indentation
        that's wider than the width of what we're trying to fill, just
        give up.  This avoids an infloop when `shr-use-fonts' in nil.

2018-04-14  Lars Ingebrigtsen  <larsi@gnus.org>

        Remove calls from string-to-multibyte in nnheader/nntp

        * lisp/gnus/nntp.el (nntp-copy-to-buffer): Apparently `insert' now
        behaves more like string-make-multibyte, but it now behaves more
        like string-to-multibyte, so remove that call here.  I'm not quite
        sure I follow that logic, but apparently there are no ill effects.

        * lisp/gnus/nnheader.el (nnheader-insert-buffer-substring): Ditto.

2018-04-14  Lars Ingebrigtsen  <larsi@gnus.org>

        Remove a string-to-multibyte from nnmh.el

        * lisp/gnus/nnmh.el (nnmh-request-list-1): Remove superfluous
        string-to-multibyte.

2018-04-14  Lars Ingebrigtsen  <larsi@gnus.org>

        Remove call to string-to-multibyte from nndoc.el

        * lisp/gnus/nndoc.el (nndoc-oe-dbx-type-p): My testing shows that
        no matter whether we're in a unibyte or a multibyte buffer, doing
        the looking-at here without the string-to-multibyte, we'll get a
        match.  We did not get a match with the call in and if we were in
        a unibyte buffer, but we presumably never are.

2018-04-14  Lars Ingebrigtsen  <larsi@gnus.org>

        Fix calculation in gnus-update-group-mark-positions

        * lisp/gnus/gnus-group.el (gnus-update-group-mark-positions):
        Rewrite a call to string-to-multibyte that didn't even work.
        After the rewrite it gives the correct result and should allow
        people to customise Gnus group process mark positions (but that's
        a pretty obscure feature).

2018-04-14  Lars Ingebrigtsen  <larsi@gnus.org>

        Removed outdated comment from nnweb.el

        * lisp/gnus/nnweb.el (nnweb-insert-html): Removed ten year old
        comment from Stefan about string-as-multibyte.

2018-04-14  Lars Ingebrigtsen  <larsi@gnus.org>

        Rewrite Gnus calls to compat function mm-multibyte-p

2018-04-14  Lars Ingebrigtsen  <larsi@gnus.org>

        Rewrite string-as-unibyte/string-as-multibyte logic in nnmail

        * lisp/gnus/nnmail.el (nnmail-insert-xref): Rewrite
        string-as-unibyte/string-as-multibyte logic and confirm that the
        result is the same in both multibyte and unibyte buffers after the
        change.

2018-04-14  Lars Ingebrigtsen  <larsi@gnus.org>

        Remove call to string-as-unibyte from nnmail

        * lisp/gnus/nnmail.el (nnmail-parse-active): Remove call to
        string-as-unibyte; the alist before and after the change are
        `equal' to each other, so it should presumably have no impact.

2018-04-14  Lars Ingebrigtsen  <larsi@gnus.org>

        Remove calls to string-as-unibyte from nnir.el

        * lisp/gnus/nnir.el (nnir-get-active): Remove two calls to
        string-as-unibyte from code that seems cargo-culted from Gnus
        functions where it is not needed, so it's presumably not needed
        here, either.

2018-04-14  Lars Ingebrigtsen  <larsi@gnus.org>

        Remove call to string-as-unibyte in gnus-start.el

        * lisp/gnus/gnus-start.el (gnus-read-newsrc-el-file): Remove
        string-as-unibyte call, which appears not to do anything much in
        modern Emacsen.

2018-04-14  Lars Ingebrigtsen  <larsi@gnus.org>

        Remove call to string-as-unibyte from gnus-start.el

        * lisp/gnus/gnus-start.el (gnus-update-active-hashtb-from-killed):
        Remove a string-as-unibyte call here, which appears not to be
        necessary: I'm able to complete over non-ASCII names both before
        and after.

2018-04-14  Lars Ingebrigtsen  <larsi@gnus.org>

        Modernise a Gnus function a bit

        * lisp/gnus/gnus-start.el (gnus-update-active-hashtb-from-killed):
        Modernise code a bit.

2018-04-14  Lars Ingebrigtsen  <larsi@gnus.org>

        Remove two string-as-unibyte in gnus-srvr.el

        * lisp/gnus/gnus-srvr.el (gnus-browse-foreign-server): We do not
        seem to need the string-as-unibyte here: We read a multibyte
        string from the *nntpd* buffer and then decode it later, and this
        apparently by some strange magic leads to the correct results in
        my test cases.

2018-04-14  Lars Ingebrigtsen  <larsi@gnus.org>

        Fix a `string-to-multibyte' in Gnus

        * lisp/gnus/gnus-art.el (gnus-request-article-this-buffer): The
        original article buffer is multibyte, and we're inserting into the
        article buffer, which is also multibyte, so the `string-to-multibyte'
        here should be unnecessary?

2018-04-14  Lars Ingebrigtsen  <larsi@gnus.org>

        Fix a string-as-unibyte in Gnus

        * lisp/gnus/gnus-art.el (gnus-article-browse-html-parts): Get rid
        of a string-as-unibyte.

        Further shr line folding/link continuation tweaks

        * lisp/net/shr.el (shr-fill-line): Tweak the link continuations
        further when folding lines.

        Indent after transforming for loop into do/while

2018-04-14  Lars Ingebrigtsen  <larsi@gnus.org>

        Make call-process work if exec-path is nil

        * src/lread.c (openp): If exec-path is nil, no files would be
        found to execute (bug#30564).

        Test cases:

         (let ((exec-path ()))
           (call-process "/bin/ls" nil (current-buffer)))

        This would previously fail, but now works.

         (let ((exec-path '("/bin/")))
           (call-process "ls" nil (current-buffer)))

        This worked, and still works.

2018-04-14  Lars Ingebrigtsen  <larsi@gnus.org>

        Make erc-current-logfile work with explicit parameter

        * lisp/erc/erc-log.el (erc-current-logfile): This function
        apparently refers to buffer-local variables, so switch to the
        buffer given before calculating the file name (bug#16111).

2018-04-14  Lars Ingebrigtsen  <larsi@gnus.org>

        Tweak shr link text property adjustments when folding

        * lisp/net/shr.el (shr-fill-line): If a link starts at the first
        word on a new folded line, then don't copy the link properties to
        the newline inserted.

2018-04-14  Lars Ingebrigtsen  <larsi@gnus.org>

2018-04-14  Lars Ingebrigtsen  <larsi@gnus.org>

        erc-truncate-buffer-on-save doc string clarification

        * lisp/erc/erc-log.el (erc-truncate-buffer-on-save): Doc
        clarification (bug#18207) since "truncate" is a word used by
        erc-truncate to mean something else.

2018-04-14  Lars Ingebrigtsen  <larsi@gnus.org>

        Ignore all-whitespace topics in erc

        (bug#25153).

2018-04-14  Lars Ingebrigtsen  <larsi@gnus.org>

        Rename url-button-google-url

        * lisp/erc/erc-button.el (erc-button-search-url): Renamed from
        url-button-google-url (bug#25717).  Suggested by Andrew Robbins.
        (erc-button-alist): Use it.

2018-04-14  John Goerzen  <jgoerzen@complete.org>  (tiny change)

        Subject: Fix problem with erc buffer renames after reconnect

        * lisp/erc/erc.el (erc-generate-new-buffer-name): Solve problem

        * src/xml.c (Flibxml_parse_html_region)
        (Flibxml_parse_xml_region): Don't mention DISCARD-COMMENTS, since

2018-04-14  Lars Ingebrigtsen  <larsi@gnus.org>

        Revert "Revert "Give better errors in signing failures in Gnus""

        This reverts commit 42141da5b0885b199636524c1e57f08ee1723aea.

        This patch was reverted in error.  I misinterpreted an email saying that
        it didn't work, but apparently it worked as it should.

2018-04-14  Lars Ingebrigtsen  <larsi@gnus.org>

        Make DISCARD-COMMENTS in `libxml-parse-{html,xml}-region' obsolete

        * doc/lispref/text.texi (Parsing HTML/XML): Mention that

        * lisp/xml.el (xml-remove-comments): New function (bug#27178).

        * src/xml.c (Flibxml_parse_html_region): Clarify what
        DISCARD-COMMENTS actually does, and say that the parameter is
        obsolete.
        (Flibxml_parse_xml_region): Ditto.

        This reverts commit ef2059e877d104bfe5abd24df05bb09c7295e4fa.

        Apparently this test triggered both when signing was successful
        and unsuccessful (bug#26298).

2018-04-14  Lars Ingebrigtsen  <larsi@gnus.org>

        Tweak mailcap precedence so that Emacs values are heeded better

        * lisp/net/mailcap.el (mailcap-parse-mailcaps): Place entries from
        system-wide mailcap files after the values that are distributed
        with Emacs, and the ones from ~/.mailcap before.
        (mailcap-parse-mailcap): Take an optional `after' parameter to

        Subject: Fix circular dependency for mm-decode

        * lisp/gnus/mm-decode.el: Do not require shr.el at the top
        of the file; `mm-shr' already requires shr.el in its body, and
        this function is the only `mm-convert-shr-links' caller (Bug#31151).

        Don't bind image commands on eww non-image links

2018-04-13  Lars Ingebrigtsen  <larsi@gnus.org>

        Make the url file: handler be less clever

        * doc/misc/url.texi (file/ftp): Remove mention of the
        url-directory-index-file variable, which is no longer consulted.

        * lisp/url/url-file.el (url-file-build-filename): Remove the DWIM
        code from the file: handler (bug#30195): It would look for
        index.html in a directory if we asked it to fetch the directory.
        Determining what to do in a directory should be left up to the
        programs that use this low-level library.  If the library decides
        to load a different file than we specified, then things start
        falling apart, as demonstrated by this bug report.

2018-04-13  Lars Ingebrigtsen  <larsi@gnus.org>

        Don't bind image commands on non-image links in Gnus

        * lisp/gnus/mm-decode.el (mm--images-in-region-p): New utility
        function.
        (mm-convert-shr-links): Only use the shr image map on links that
        contain images.  This avoids binding commands like `r' on links
        that don't need it.

2018-04-13  Lars Ingebrigtsen  <larsi@gnus.org>

        Revert "Add colors to faces that lack them."

        This reverts commit 16748a5f6bd57ec0967ecb5e14ffe8af5f43d888.

        From the discussion on the ding mailing list, I said:

        I think the colours should be reverted back to what they were before the
        change.  Normal text should be white on black (if you have a dark
        background), and colours should be used to emphasise or de-emphasise
        certain text.  Following that principle, normal Gnus groups should be
        white, not ... er...  what are they now?  Teal?

2018-04-13  Lars Ingebrigtsen  <larsi@gnus.org>

        Tweak the fonts applied to shr indentation

        * lisp/net/shr.el (shr-fill-line): Don't use fonts (especially

2018-04-13  Lars Ingebrigtsen  <larsi@gnus.org>

        Further tweak point placement on gnus-summary-select-article-buffer

        * lisp/gnus/gnus-sum.el (gnus-summary-select-article-buffer):
        Place point in the empty space between headers and body.

2018-04-13  Lars Ingebrigtsen  <larsi@gnus.org>

        Tweak point placement in *Group* on `Q' exit

        * lisp/gnus/gnus-sum.el (gnus-summary-exit-no-update): When
        exiting the summary buffer with `Q', move point to the next unread
        group (which is the same thing that happens on `q' exit.)

2018-04-13  Lars Ingebrigtsen  <larsi@gnus.org>

        Tweak point placement in gnus-summary-select-article-buffer

        * lisp/gnus/gnus-sum.el (gnus-summary-select-article-buffer):
        Tweak where point is placed because when the user selects the
        article buffer, it's probably to cite something or click on
        something, and not do anything with the headers.

2018-04-13  Lars Ingebrigtsen  <larsi@gnus.org>

        Compute erc line lengths correctly for utf-8 (etc.)

        * lisp/erc/erc-backend.el (erc-split-line): Fold the lines

        Further fix to eieio-persistent

        * lisp/emacs-lisp/eieio-base.el (eieio-persistent-validate/fix-slot-value):
          Make handling of hash tables and vectors recursive. This is
          necessary because the write process, in `eieio-override-prin1' is
          also recursive. With any luck, this will be the last fix of its
          kind. If that's true, cherry-pick to Emacs 26.2 later on.

        Handle quotation marks and apostrophes in ‘sgml-quote’

        To be able to use text in an HTML argument, quotation marks need
        to be replaced with an appropriate character reference.  Make
        ‘sgml-quote’ do that.

        While at it, fix entiteis not being unquoted if they lack closing
        semicolon (e.g. ‘&amp’) occurring at the very end of a region.
        Even though unlikely, make ‘sgml-quote’ handle this scenario.

        * lisp/textmodes/sgml-mode.el (sgml-quote): Handle quotation marks and
        apostrophes.  Match entities lacking semicolon at the end of regions.
        * test/lisp/textmodes/sgml-mode-tests.el (sgml-quote-works): New test

        Introduce new macro combine-change-calls

        This macro is a bit like combine-after-change-calls, but also works with a
        non-null before-change-functions.  It suppresses the operation of the change
        hooks on a possibly large sequence of buffer modifications, replacing them
        with a single invocation of before-change-functions at the start, and a single
        invocation of after-change-functions at the end.

        Fix constant folding of overflows

        This suppresses some byte-code optimizations that were invalid in
        the presence of integer overflows, because they meant that .elc
        files assumed the runtime behavior of the compiling platform, as
        opposed to the runtime platform.  Problem reported by Pip Cet in:
        https://lists.gnu.org/r/emacs-devel/2018-03/msg00753.html

        When considering markers (to find a starting point for the conversion),
        typically one of the two bounds is nearby (coming from
        cached_(byte|char)pos) but the other is far (point-min or point-max),
        so change the exit condition so we stop as soon as *one* of the bounds
        is near.

        (BYTECHAR_DISTANCE_INITIAL, BYTECHAR_DISTANCE_INCREMENT): New constants.
        (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Use them to try and

        Allow `&rest' or `&optional' without following variable (Bug#29165)

        This is sometimes convenient when writing macros, so that the empty
        variable case doesn't need to be handled specially.  Older versions of
        Emacs accepted this in some cases (especially the interpreter in Emacs
        25 and below was very accepting).

        Avoid Fortran-style floating-point optimization

        When optimizing arithmetic operations, avoid optimizations that
        are valid for mathematical numbers but invalid for floating-point.
        For example, do not optimize (+ 1 v 0.5) to (+ v 1.5), as they may
        not be the same due to rounding errors.  In general,
        floating-point numbers cannot be constant-folded, since that would
        make .elc files platform-dependent.
        * lisp/emacs-lisp/byte-opt.el (byte-optimize-associative-math):
        Do not optimize floats.

        (byte-optimize-minus): Do not optimize (- 0 x) to (- x).
        (byte-optimize-multiply): Do not optimize (* -1 x) to (- x).
        (byte-optimize-divide): Do not optimize (/ x -1) to (- x).
        (logand, logior, logxor): Optimize with byte-optimize-predicate
        instead of with byte-optimize-logmumble.

        Don't call swap_in_symval_forwarding since the currently swapped
        binding is never one we've modified.
        (Fkill_local_variable): Use swap_in_global_binding rather than messing

        Fix byte-opt lists of pure functions etc.

        This fixes a bug where a byte-compiler running on 64-bit Emacs
        optimized (lsh -1 -1) to #x1fffffffffffffff, an optimization
        that is incorrect for .elc files intended for either 32- or
        64-bit Emacs.  While I was in the neighborhood, I noticed other
        glitches in the lists of pure and side-effect-free functions, and
        fixed the errors that I found.
        * lisp/emacs-lisp/byte-opt.el (side-effect-free-fns):
        Move some functions here from side-effect-and-error-free-fns,
        since they can now signal errors.  The affected functions are
        current-time-string, current-time-zone,
        line-beginning-position, line-end-position.  Rename langinfo
        to locale-info.  Add logcount.  Remove string-to-int.
        (side-effect-and-error-free-fns): Remove minibuffer-window, a
        function that can signal errors, and that is already in
        side-effect-free-fns.
        (pure-fns): Remove ash, lsh, and logb, since they are
        platform-dependent and .elc files should be
        platform-independent.  Add %, logand, logcount.  Sort.
        Clarify what is meant by “pure”.

        Revert move of interactive `transpose-regions' to Lisp

        This reverts my commit 3a3aa0e056a of 2018-03-18 at 21:43:18 UTC.
        I thought consensus had been reached, but it had not: Eli Zaretskii
        felt the pre-3a3aa0e056a situation was fine and would not like to
        see it changed without at least further discussion.

        Various follow-ups for early init file changes

        * doc/emacs/custom.texi (Early Init File): Add more details about
        which variables must be set in the early init file rather than the
        regular init file.  See
        https://lists.nongnu.org/archive/html/bug-gnu-emacs/2018-02/msg00827.html

        * lisp/emacs-lisp/package.el (package-enable-at-startup): Update
        docstring to note that packages are now made available before loading
        the init file, rather than afterwards.  See
        https://lists.gnu.org/r/emacs-devel/2018-02/msg00632.html
        (package-load-list): Refer to "making available" rather than "loading"

        * lisp/startup.el (command-line): Call `custom-reevaluate-setting' on
        predefined variables before loading the early init file and before
        `package-initialize' is called.  This prevents
        `Info-default-directory-list' from being unbound when
        `package-initialize' tries to access it during startup.  See
        https://lists.gnu.org/r/emacs-devel/2018-02/msg00545.html

        Move interactive `transpose-regions' to Lisp

        Define `transpose-regions' in Lisp, because its complex interactive
        spec was ungainly in C, and change the C version to non-interactive
        `transpose-regions-internal'.  The Lisp function is just a wrapper
        around the C function, which still does all the work.

        * lisp/simple.el (transpose-regions): New wrapper function, with
          interactive spec taken from old C `transpose-regions'.

        * src/editfns.c (Ftranspose_regions): Rename to...
          (Ftranspose_regions_internal): ...here, and remove interactive spec.

        Improve port to NetBSD tzalloc

        Problem reported by Valery Ushakov (Bug#30738#13).
        * src/editfns.c (tzlookup) [__NetBSD_Version__ < 700000000]:
        If tzalloc fails for any reason other than memory exhaustion,
        assume it’s because NetBSD 6 does not support tzalloc on
        POSIX-format TZ strings, and fall back on tzdb if possible.

        * src/sysdep.c (list_system_processes) [HAVE_PROCFS]: Allow pids

        reverts my patch 2018-03-09T20:06:05Z!eggert@cs.ucla.edu, which

        simplify the code, and permit toggling the hidden command options.
        (grep-mode-map): Add a menu-bar item and new separator for
        'grep-find-toggle-abbreviation', and fix the incumbent separators
        in the "Grep" menu-bar, of which only one was showing before this

        Add early init file, stop package-initialize insertion

        Discussion on emacs-devel leading up to this change (approximately 150

        Fix wait_reading_process_output wait_proc hang

        * src/process.c (read_process_output): Track bytes read from
        a process.
        (wait_reading_process_output): If called recursively through
        timers and/or process filters via accept-process-output, it is
        possible that the output of wait_proc has already been read by
        one of those recursive calls, leaving the original call hanging
        forever if no further output arrives through that fd and no
        timeout has been set.  Fix that by using the process read
        accounting to keep track of how many bytes have been read and
        use that as a condition to break out of the infinite loop and
        return to the caller as well as to calculate the proper return
        value (if a wait_proc is given that is).

        * src/process.h (struct Lisp_Process): Add nbytes_read to track
        bytes read from a process.

        initially shows the correct buffer.
        (server-process-filter): Pass a lambda to server-execute to create

        beginning of defun in moving backwards over comments.

        Stop keeping multiple doc copies for items defined multiple times

        It was always a nuisance to keep all the copies in sync.

        Instead, skip individual doc strings starting with "SKIP".
        * doc/lispref/internals.texi (Writing Emacs Primitives):

        * lisp/server.el (server--external-socket-initialized): Rename
        from server-external-socket-initialised, since it should be
        private and Emacs uses American spelling.  All uses changed.
        * src/emacs.c, src/lisp.h: Revert previous changes, as the
        initialization is now done in src/process.c, which already
        includes the relevant files.
        * src/process.c (union u_sockaddr): Move decl to top level.

        have main.c do it.  Use conv_sockaddr_to_lisp instead of doing

        Support standard Terminfo direct mode terminals

        Latest Terminfo introduces terminal definitions that support direct
        color mode.  The "Co"/"colors" capability is set to 0x1000000 on these
        terminals and Emacs is already compatible with them.
        However, if used Terminfo library hasn't been compiled with 32-bit
        value support, "Co"/"colors" is truncated to 0x7fff.  In this case
        direct color mode support can be detected from the "RGB" capability
        flag.
        There are some minor problems if the color count isn't corrected from
        0x7fff.  First eight standard colors defined in xterm-standard-colors
        are shown correctly.  However, their RGB values match the terminal
        settings, not the RGB values defined in xterm-standard-colors.  Bright
        versions of these colors are shown incorrectly.  They are interpreted
        as pixels #000008 - #000015, which are very dark shades of blue.

        * src/term.c (init_tty): Force terminal color count to 0x1000000 if
        "RGB" capability is present.
        * src/tparam.h: Define prototype for tigetflag.  (Bug#30308)

        * doc/misc/efaq.texi (Colors on a TTY): Add information about direct
        mode terminals supported by Terminfo.

        encountering a module, but use the normal loading machinery to
        properly set up load-history, check for recursive loads, print
        messages, etc.

        * test/src/emacs-module-tests.el (module/load-history): New test.
        (module/describe-function-1): Adapt test.

        * etc/NEWS: Mention fixed behavior.

2018-02-02  Philipp Stephani  <phst@google.com>

        Use 'defalias' in test module instead of 'fset'.

        This puts functions defined in the module into the 'load-history'.

        * test/data/emacs-module/mod-test.c (bind_function): Use 'defalias'
        instead of 'fset'.

        * test/src/emacs-module-tests.el (module/describe-function-1): Adapt
        unit test.

2018-02-02  Philipp Stephani  <phst@google.com>

        Add support for module functions to C-h f (Bug#30163).

        * lisp/help-fns.el (help-fns-function-description-header): Handle
        module functions.

        * test/src/emacs-module-tests.el (module/describe-function-1): New
        test.

        (file-notify-test-remote-temporary-file-directory):

2018-02-01  Noam Postavsky  <npostavs@gmail.com>

        Test and fix "/:" quoted file name handlers (Bug#30243)

        Some w32 specific problems were discovered, but only worked around, as
        these are not serious, and not the focus of this bug fix:
            - The w32 implementation of `insert-directory doesn't handle a nil
            SWITCHES argument.
            - `dired-compress-file' does not operate correctly if the unquoted
            filename contains a ":" (e.g., C:/foo/bar).

        * lisp/files.el (file-name-non-special): Strip the "/:" from
        `default-directory' for `temporary-file-directory' operation; both
        arguments to `file-name-completion', `file-name-all-completion', and
        `file-equal-p' operations; `buffer-file-name' for
        `make-auto-save-file-name' and 'set-visited-file-modtime' operations.
        Don't touch any operands of `file-notify-rm-watch' and
        `file-notify-valid-p' as they receive descriptors; not file
        names (this is not sufficient to fix these operations for "/:" quoted
        file names though, these are fixed in a later commit).

        * test/lisp/files-tests.el (files-tests--with-temp-file): Give it a
        `debug' property.
        (files-tests--with-temp-non-special): New helper macro.

        Fix some errors in c-display-defun-name when the type is "struct {..}", etc.

        Also fix some errors with c-display-defun-name when there are nested classes.

        * lisp/progmodes/cc-cmds.el (c-in-function-trailer-p): Deal with a struct {..}
        being merely the type of a function.
        (c-where-wrt-brace-construct): Deal with a struct {..} being merely the type
        of a function.  Rearrange the order of some Lisp forms.  Insert a check for
        c-protection-key ("private", etc.) alongside the checking for a label.
        (c-defun-name-1): New function extracted form c-defun-name, which works within
        the existing restriction.  Don't regard 'at-function-end as being within the
        defun any more.  Recognize "struct", etc., with the new
        c-defun-type-name-decl-key rather than c-type-prefix-key.  Make the
        recognition of a normal function more accurate.
        (c-defun-name): Part left after extracting the above function.  It now just
        widens and calls c-defun-name-1.
        (c-declaration-limits-1): New function extracted from c-declaration-limits,
        which works within the existing restriction.  Move LIM back one block to
        account for the possibility of struct {..} as a function type.  Check we're
        not inside a declaration without braces.
        (c-declaration-limits): Part left after extracting the above function.  It now
        just narrows to an enclosing decl block and calls c-declaration-limits-1.
        (c-defun-name-and-limits): New function which identifies the name and limits
        of the most nested enclosing declaration or macro.
        (c-display-defun-name): Use c-defun-name-and-limits rather than two separate
        functions (which didn't always agree on which function).

        * lisp/progmodes/cc-engine.el (c-beginning-of-statement-1): If we have struct
        {..} as the type of a function, go back over this, too.

        * lisp/progmodes/cc-langs.el (c-defun-type-name-decl-kwds)
        (c-defun-type-name-decl-key): New lang const/var.

        Fix round tripping of read->print for symbols with strange quotes

        Since 2017-07-22 "Signal error for symbol names with strange
        quotes (Bug#2967)", symbol names beginning with certain quote
        characters require an escaping backslash.  However, the corresponding
        change for printing missed, so that (eq (read (prin1-to-string SYM))
        SYM) does not give `t' for such symbols.
        * src/character.c (confusable_symbol_character_p): New function,
        extracted from test `read1'.
        * src/lread.c (read1): Use it.
        * src/print.c (print_object): Use it to print a backslash for symbols
        starting with characters that `read1' requires to be escaped.

        Raise limit of regexp repetition (Bug#24914)

        * src/regex.h (RE_DUP_MAX): Raise limit to 2^16-1.
        * etc/NEWS: Announce it.
        * doc/lispref/searching.texi (Regexp Backslash): Document it.
        * test/src/regex-tests.el (regex-repeat-limit): Test it.

        * src/regex.h (reg_errcode_t): Add REG_ESIZEBR code.
        * src/regex.c (re_error_msgid): Add corresponding entry.
        (GET_INTERVAL_COUNT): Return it instead of the more generic REG_EBADBR
        when encountering a repetition greater than RE_DUP_MAX.

        * lisp/isearch.el (isearch-search): Don't convert errors starting with
        "Invalid" into "incomplete".  Such errors are not incomplete, in the
        sense that they cannot be corrected by appending more characters to
        the end of the regexp.  The affected error messages are:

        - REG_BADPAT "Invalid regular expression"
          - \\(?X:\\) where X is not a legal group number
          - \\_X where X is not < or >

        - REG_ECOLLATE "Invalid collation character"
          - There is no code to throw this.

        - REG_ECTYPE "Invalid character class name"
          - [[:foo:] where foo is not a valid class name

        - REG_ESUBREG "Invalid back reference"
          - \N where N is referenced before matching group N

        - REG_BADBR "Invalid content of \\{\\}"
          - \\{N,M\\} where N < 0, M < N, M or N larger than max
          - \\{NX where X is not a digit or backslash
          - \\{N\\X where X is not a }

        - REG_ERANGE "Invalid range end"
          - There is no code to throw this.

        - REG_BADRPT "Invalid preceding regular expression"
          - We never throw this.  It would usually indicate a "*" with no
            preceding regexp text, but Emacs allows that to match a literal
            "*".

        Fix some tooltip related problems

        Replace 'tooltip' frame parameter with a 'tooltip' member in
        the frame structure.  For GTK+ builds use 'tip_last_frame' to

        member to true.
        (x_hide_tip): Rewrite with additional tests of frames for

        cl-loop: Add missing guard condition

        Consider the expansion of `cl-loop' with a `for' clause and more
        than one internal variables, X, Y, processed in parallel.
        Each step updates X and Y right after update the loop variable, K; if
        either X or Y depend on K, then some forms of the body are
        evaluated with the wrong K (Bug#29799).

        For instance, consider the following code:
        (cl-loop for k below 2
                 for x = (progn (message "k = %d" k) 1)
                 and y = 1)

        This code should show in *Messages*:
        k = 0
        k = 1

        Instead, the code shows:
        k = 0
        k = 1
        k = 2

        To prevent this we must ensure that the loop condition is still
        satisfied right after update the loop variable.
        In the macro expansion of the example above, right after:
        (setq k (+ k 1))

        evaluate the rest of the body forms if the condition
        (< k 2)
        is still valid.

        * lisp/emacs-lisp/cl-macs.el (cl--loop-guard-cond): New variable.
        (cl--parse-loop-clause): Set it non-nil if the loop contains
        a for/as clause.
        (cl-loop): After update the loop variable, evaluate the remaining of
        the body forms just if the loop condition is still valid (Bug#29799).

        * test/lisp/emacs-lisp/cl-macs-tests.el (cl-macs-loop-for-as-equals-and):

        Fix command repetition with lexical-binding (Bug#29334)

        `call-interactively' relies on analyzing the source of `interactive'
        forms in order to preserve arguments like (region-end) in the command
        history, rather than just storing the resulting position.  However,
        the byte-compiler does not preserve the source of the interactive form
        when lexical-binding is in effect, because `call-interactively' would
        evaluate the form with dynamic binding in that case.

        To fix this, change `call-interactively' so that it checks compiled
        functions for lexical-binding as well.  Then the byte-compiler can
        preserve the source of interactive forms regardless of the value of
        lexical-binding.

        * src/callint.c (Fcall_interactively): Functions compiled with
        lexical-binding have their arglist encoded as an integer, use this to
        choose the right kind of binding for compiled functions too.
        * lisp/emacs-lisp/bytecomp.el (byte-compile-lambda): Preserve the
        uncompiled form of the interactive form when lexical-binding is
        enabled too.

        closing parentheses, causing an unrelated error.

        * lisp/gnus/gnus-registry.el (gnus-registry-fetch-recipients-fast,
          gnus-registry-fetch-sender-fast): First, delete
          `gnus-registry-fetch-header-fast'. It was being called with reversed
          arguments, and thus always returned nil, but even if the argument
          order was correct it would have raised an error, as it was trying to
          `assq' a string in a vector. Instead, just have these two functions
          do their own work, as they're doing fairly different things.

        * configure.ac: Go back to not defining CHECK_LISP_OBJECT_TYPE by
        default for developer builds, since it is no longer that useful.
        We can make it a no-op entirely later, if in practice it's not
        that helpful to enable it.

        Don't compare arguments that can be nil

        copy-region-as-kill can be called passing nil as `beg' and

        Narrow pointer bounds when appropriate

        This typically occurs in a storage manager, where the caller
        is expected to access only the newly-allocated object,

        parts of the heap.

        Port to gcc -fcheck-pointer-bounds

        This is a minimal port, just to get Emacs running;
        it does not attempt to make the pointer bounds at all tight.
        * src/ptr-bounds.h: New file.
        * src/alloc.c, src/gmalloc.c: Include it.
        * src/alloc.c (live_string_holding, live_cons_holding)
        (live_symbol_holding, live_misc_holding, garbage_collect_1)
        (sweep_conses, sweep_floats):
        * src/gmalloc.c (malloc_initialize_1, _free_internal_nolock)
        (_realloc_internal_nolock):
        Widen pointer bounds as necessary.
        We're in a memory allocator so this is OK.
        * src/lisp.h (lisp_h_XSYMBOL, make_lisp_symbol) [__CHKP__]:
        Do not convert from pointer to integer and back again, so
        that GCC does not lose track of pointer bounds.
        (XSYMBOL) [__CHKP__ && !USE_LSB_TAG]: Now a compile-time error.
        Although it's possible to support both -fcheck-pointer-bounds and
        --with-wide-int, it's more work; keep things simple for now.
        (DEFINE_LISP_SYMBOL) [__CHKP__]: Now a no-op, to avoid
        trouble with unbounded pointers.

        Reimplement Lisp_Object as pointer-to-incomplete

        This makes Lisp_Object values opaque pointers instead of integers,
        which helps avoid the same sort of typos that
        CHECK_LISP_OBJECT_TYPE helps to avoid, without having to wrap
        pointers inside structures.  This also looks forward to supporting
        -fcheck-pointer-bounds.
        * etc/DEBUG:
        * src/.gdbinit (Lisp_Object_Printer.to_string):

        incomplete type.  Keep pointers pointers, as much as possible.
        * src/alloc.c (macro_XPNTR_OR_SYMBOL_OFFSET, XPNTR_OR_SYMBOL_OFFSET):
        Remove.  All uses replaced by plain XPNTR.

        * src/xwidget.c (webkit_javascript_finished_cb): Use XPL
        instead of XIL with a non-EMACS_INT arg.
        (Fxwidget_webkit_execute_script): Use XLP instead of XLI
        followed by two conversions.

        Ensure that we can find definitions when buffer is narrowed

        find-function-search-for-symbol will reuse the existing buffer if
        we've already opened the file that contains this symbol. However, if
        the user has narrowed that buffer, we can't find definitions outside
        the narrowed area.

        Instead, search the whole file to find definitions, and teach the help
        buttons to widen if necessary.

        For help commands, ensure all keys of a mouse sequence are reported.

        This solves the problem where read_key_sequence initializes and uses a global
        buffer raw_keybuf, yet is called recusrsively.  The initialization is now done
        elsewhere, avoiding the reinitialization of that global buffer.

        * src/keyboard.c (command_loop_1, read_key_sequence_vs): Initialize
        raw_event_count before calling read_key_sequence.
        (read_char_x_menu_prompt): Call x_popup_menu_1 in place of Fx_popup_menu.
        (init_raw_keybuf_count): New function.
        (read_key_sequence): Remove initialization of raw_event_count.  Add a missing
        GROW_RAW_KEYBUF invocation.

        * src/keyboard.h: (init_raw_keybuf_count): New declaration.

        * src/menu.c: (x_popup_menu_1): New function with the functionality of the
        former Fx_popup_menu.
        (Fx_popup_menu): Replace with function which initializes raw_event_count then
        calls x_popup_menu_1.

        * src/menu.h: (x_popup_menu_1): New declaration.

2017-11-24  Sam Steingold  <sds@gnu.org>

        Fix last patch: ensure the return value of tags-verify-table.

        * lisp/progmodes/etags.el (tags-verify-table): Since `(tags-table-mode)'
        always return nil now that it is a derived mode, call
        `verify-tags-table-function' explicitly.

2017-11-22  Sam Steingold  <sds@gnu.org>

        * lisp/progmodes/etags.el (tags-table-mode): Define using
        `define-derived-mode', inheriting from `special-mode'.
        Not only the buffer is now read-only, but you can bury it with "q".

        * lisp/gnus/gnus-score.el (gnus-summary-current-score): The only point

          need to do gnus-message filtering.

2017-11-20  Alan Mackenzie  <acm@muc.de>

        read_key_sequence: correct the handling of raw_keybuf in recursive calls

        This fixes bug #29349.

        * src/keyboard.c (raw_keybuf_buffer, raw_keybuf_count_buffer): New variables
        pointed to by ...
        (raw_keybuf, raw_keybuf_count): Variables converted to pointers.
        (GROW_RAW_KEYBUF): enhance with a length argument.
        (command_loop_1): Initialize the above two pointers to their canonical values.

        (read_key_sequence): In recursive calls (for menus) the function was
        overwriting the raw event buffer of the outer call.  Correct this by
        introducing a local buffer for each level of call, and setting this up to be
        used by the call to read_char.  Any contents of this local buffer are appended
        to the global buffer afterwards.

        Rename Man-build-section-alist (bug#28998)

        The defsubst Man-build-section-alist builds and returns a list of
        strings, so rename it to Man-build-section-list and make it a defun.

        * lisp/man.el (Man-build-section-alist): Do it and reduce syntax.
        (Man-goto-page):
        * lisp/woman.el (woman-find-file): Use it.

          object name is printed for each object, and whether an object's
          contents are indented or not. Object names are obsoleted; omitting
          indentation reduces the size of persistence files.

        Expand recognized time intervals for MPC seeking

        Now accepts [+-]H:M:S and subsets.  Also accepts some odd variations of
        it since the regexp is not strict.  One unpleasant caveat is that
        string-to-number simply returns zero on failure instead of signaling an
        error.  At the moment, there are cases where instead of getting
        a user-error, the seek may simply not go where one expects it.
        * lisp/mpc.el (mpc-read-seek): New function.
        (mpc-seek-current): Use it.

        Update view-mode docstring

        Not all the kill commands save the text in the kill ring
        by default (e.g. `kill-rectangle').
        It is more precise to just say that the kill commands save
        the text and do not change the buffer (Bug#36741).

        Fix subproc listening when setting filter to non-t (Bug#36591)

        * src/process.c (Fset_process_filter): Call add_process_read_fd
        according to the state of process filter before it's updated.  This
        restores the correct functioning as it was before 2016-02-16 "Allow
        setting the filter masks later".  Inline the set_process_filter_masks
        call instead of fixing it that function, because it is also called
        from connect_network_socket, and we don't want to change the behavior
        of that function so close to release.
        * test/src/process-tests.el (set-process-filter-t): New test.

        Use plain symbols for eieio type descriptors (Bug#29220)

        Since Emacs 26, eieio objects use a class record (with circular
        references) as the type descriptor of the object record.  This causes
        problems when reading back an object from a string, because the class
        record is not `eq' to the canonical one (which means that read objects
        don't satisfy the foo-p predicate).
        * lisp/emacs-lisp/eieio.el (make-instance): As a (partial) fix, set
        the record's type descriptor to a plain symbol for the type descriptor
        when eieio-backward-compatibility is non-nil (the default).

        Let dir locals for more specific modes override those from less

        The list of dir local variables to apply is now sorted by the number
        of parent modes of the mode used as the key in the association list.
        That way when the variables are applied in order the variables from
        more specific modes will override those from less specific modes.

        If there are directory entries in the list then they are sorted in
        order of name length.  The list of modes for that dir is then
        recursively sorted with the same mechanism.  That way variables tied
        to a particular subdirectory override those in a parent directory.

        Previously the behavior didn’t seem to be well defined anyway and was
        dependent on the order they appeared in the file.  However this order
        was changed in version 26.1 and it probably also depended on the
        number of dir-local files that are merged.

        Dear eamcs developers, eshells current documentation first states
        that alias definitions are not saved to an alias file, later that
        they are saved to an alias file.  I tested it and the latter is
        correct.

        Please find attached a patch which fixes this.

        Thanks for working on emacs which is really great, Gregor

        Problem reported by Eli Zaretskii in:
        https://lists.gnu.org/r/emacs-devel/2018-08/msg00380.html
        * src/data.c (arithcompare): Work around incompatibility
        between gcc -fexcess-precision=fast and the C standard on x86,

        might not work in general, it does work here and is probably
        good enough for the platforms we care about.

        Prevent line-mode term from showing user passwords

        For buffers whose mode derive from comint-mode, the user password is

        rcirc does not retain the server alias on reconnect.  As a result, rcirc
        fails to re-use server and channel buffers when an alias is used.  Further
        problems may ensue when aliases are used to differentiate multiple
        connections to the same host, for example when using a single IRC bouncer
        or proxy to connect to multiple IRC networks.

        Save the server alias when connecting to a server so that reconnect will
        retain the alias.

        signal an error when passed both :server and :nowait non-nil.  In
        Emacs 25, :nowait would be ignored in this case, but as of Emacs 26.1
        this gives an error, albeit an unclear one.  Also remove obsolete
        comment regarding configurations lacking non-blocking mode, the
        corresponding code was removed in 2012-11-17 "Assume POSIX 1003.1-1988
        or later for fcntl.h."

        (Freplace_buffer_contents): Set up ctx.beg_a and ctx.beg_b.
        (buffer_chars_equal): Use ctx->beg_a and ctx->beg_b instead of
        calling BUF_BEGV, which is expensive.  This speeds up the recipe
        in bug#31888 by 30%.

        * doc/emacs/docstyle.texi: Avoid messing up the html output.

        (Freplace_buffer_contents): Initialize a_unibyte, b_unibyte, and
        rbc_quitcounter.  Inhibit modification hooks if they were not
        already inhibited.  Use rarely_quit to allow user to quit, to
        avoid calling maybe_quit too frequently (which hurts performance).
        Remove redundant assertions (which hurt performance too much).
        Call signal_after_change and update_compositions after all the
        changes are done.
        (buffer_chars_equal): Remove redundant assertions (which hurt
        performance).  Avoid using BUF_FETCH_CHAR_AS_MULTIBYTE, which
        hurts performance by referencing Lisp symbols; instead, use
        lower-level macros with explicit tests to select which macro to
        use.  (Bug#31888)

2018-06-26  Noam Postavsky  <npostavs@gmail.com>

        Detect a non-list package archive content properly (Bug#22311)

        * lisp/emacs-lisp/package.el (package--download-one-archive): Use
        `read' instead of `read-from-string'; the latter always returns a
        cons, so the `listp' check on its return value doesn't make sense.  It
        was changed from `read' to `read-from-string' in 2015-04-01 "*
        emacs-lisp/package.el: Implement asynchronous refreshing", but that
        change was not needed because `read' works fine on strings as well as
        buffers.

        * lisp/ido.el (ido-fallback): New variable.
        (ido-buffer-internal, ido-file-internal): Reset ido-fallback to nil
        before prompting user.  Use ido-fallback when ido-exit is 'fallback'.
        (ido-fallback-command): Add optional FALLBACK-COMMAND argument.

        Use swap_in_global_binding to swap out any local binding, instead of
        a mix of find_symbol_value followed by messing with where&found.
        Don't call swap_in_symval_forwarding since the currently swapped
        binding is never one we've modified.
        (Fkill_local_variable): Use swap_in_global_binding rather than messing

        This reverts commit 8b50ae8b2284b5652c2843a9d0d076f4f657be28.

        According to tests in bug#27656 by OGAWA Hirofumi, this patch
        led to wrong results when binding

        (dolist (addr '("Rasmus <rasmus@gmx.us>" "Rasmus <mbox@gmx.us>"))
          (dolist (ignore-single '(t nil))

        Fix wait_reading_process_output wait_proc hang

        * src/process.c (read_process_output): Track bytes read from
        a process.
        (wait_reading_process_output): If called recursively through
        timers and/or process filters via accept-process-output, it is
        possible that the output of wait_proc has already been read by
        one of those recursive calls, leaving the original call hanging
        forever if no further output arrives through that fd and no
        timeout has been set.  Fix that by using the process read
        accounting to keep track of how many bytes have been read and
        use that as a condition to break out of the infinite loop and
        return to the caller as well as to calculate the proper return
        value (if a wait_proc is given that is).

        TO_CHARPOS, but didn't yet produce glyphs for that buffer

        Before this patch, after the terminal process dies the command

        post-command-hook because the process is dead.  (Bug#31236)

        Let eieio-persistent-read read what object-write has written

        * lisp/emacs-lisp/eieio-base.el (eieio-persistent-validate/fix-slot-value):
          `object-write' may quote lists inside hash tables and vectors, so
          unquote those lists here.

        This patch allows the eieio-persistent write/restore process to
        perform a clean round trip. It only handles a very specific and
        limited range of object structures, but at least the write and read
        procedures match.

        Define if-let* and derivatives as aliases for if-let etc

        This commit reverts declaring `if-let' and `when-let' obsolete in
        favor of the new `if-let*' and `when-let*' versions because of the
        compiler warning mess (Bug#30039).  Instead we make foo-let* aliases
        for foo-let.  The old single-tuple variable spec case is still
        supported for backward compatibility.
        * lisp/emacs-lisp/subr-x.el (if-let, when-let): Don't declare
        obsolete.  Tweak edebug specs.

        Avoid memory corruption with specpdl overflow + edebug (Bug#30481)

        If grow_specpdl fails due to outgrowing max_specpdl_size, it will
        signal an error *before* growing the specpdl array.  Therefore, when
        handling the signal, specpdl_ptr points past the end of the specpdl
        array and any further use of specpdl before unwinding (e.g., if
        edebug binds signal-hook-function) will cause memory corruption.
        * src/eval.c (signal_or_quit): Don't call `signal-hook-function' if
        the specpdl_ptr is already past the end of the specpdl array.

        Revert "Signal error for symbol names with strange quotes (Bug#2967)"

        That commit did not make the corresponding change to printing, thus
        breaking the (eq (read (prin1-to-string SYM)) SYM) invariant for those
        symbols.  It's too late in the release cycle to change printing
        behavior, therefore revert the reader change.

        Don't merge to master, the print function will be updated there (see
        "Fix round tripping of read->print for symbols with strange quotes").

        Allow read-passwd to hide characters inserted by C-y.  (Security fix.)

        This fixes bug #30186.  The with-silent-modifications was there to prevent
        records of text property manipulations being put into buffer-undo-list.  These
        had been causing a significant slowdown in CC Mode with C-_ after a large
        C-y.  This CC Mode problem has since been solved by a different workaround.

        This reverts commit 4fd446e9f65e5531b18d4a0c5e08a6eeabc292d8:
        * lisp/emacs-lisp/bytecomp.el (byte-compile-file):
        Put tempfile next to the target file, as was the original intent.

2018-01-19  Paul Eggert  <eggert@cs.ucla.edu>

        Fix tempfile creation when byte compiling

        This improves on the recent fix for master failing to build
        on FreeBSD.  Suggested by Stefan Monnier in:
        https://lists.gnu.org/r/emacs-devel/2018-01/msg00600.html
        * lisp/emacs-lisp/bytecomp.el (byte-compile-file):

        Unbreak building Emacs on FreeBSD

        the temporary file under temporary-file-directory if the file
        being compiled is specified by an absolute file name.  This avoids
        problems with ACL copying from temporary-file-directory on
        FreeBSD.  For the details, see

2018-01-19  Callum Cameron  <cjcameron7@gmail.com>  (tiny change)

        Check to see if there is an incomplete command at the end of

        "Switch term.el to lexical binding, and clean up code a bit".

        CC Mode: stop distinguishing brace blocks from defun blocks by content.

        Don't merge to master; this is a quick fix for the emacs-26 branch.  This is
        essentially a reversion of the patch from 2017-11-10 which attempted to handle
        C99's compound literals.

        The bug here was triggered when a defun block contained a declaration ending
        in a comma, yet without a semicolon.

        * lisp/progmodes/cc-engine.el (c-guess-basic-syntax): At the CASE 9 test,
        remove from the `or' form the test of a block's contents.

        Make c-defun-name analyze more thoroughly a function type which is a struct

        This fixes bug #29293.

        * lisp/progmodes/cc-cmds.el (c-defun-name): When a struct (etc.) type is
        encountered, check whether it is the return type of a function rather than a
        declaration of the struct itself.  Similarly adapt the cond arm which deals
        with functions properly to recognize struct return types.

        Filter obtrusive events in help-read-key-sequence.

        This fixes most of bug #29272.

        * lisp/help.el (help-read-key-sequence): After a mouse event, pause for 0.01s,
        discarding any events (such as <help-echo>) received in this time, before
        polling for the double-click (etc.) events which may follow.  This fixes the
        infinite loop which occurred whwn <help-echo> events triggered a sit-for
        whilst handling menu events.

        More fixes in src/.gdbinit

        * src/.gdbinit (pwinx): Update to match 'struct window'.

        or 'body'.

2017-11-13  Paul Eggert  <eggert@cs.ucla.edu>

        Port to IBM xlc 12.01

        Work around a compiler bug by using a separate enum for alignment.
        * src/alloc.c (roundup_size): Declare in a separate enum.

2017-11-13  Paul Eggert  <eggert@cs.ucla.edu>

        Simplify by removing HAVE_STRUCT_ATTRIBUTE_ALIGNED

        * configure.ac (HAVE_STRUCT_ATTRIBUTE_ALIGNED): Remove.  No longer
        needed, since we no longer rely on __attribute__ ((aligned (8))).
        All uses removed.
        * src/emacs-module.c (HAVE_STRUCT_ATTRIBUTE_ALIGNED): Remove.
        (lisp_to_value): Simplify now that we no longer need to worry
        whether HAVE_STRUCT_ATTRIBUTE_ALIGNED is false.

2017-11-13  Paul Eggert  <eggert@cs.ucla.edu>

        Use alignas to fix GCALIGN-related bugs

        Use alignas and unions to specify alignments of objects needing
        addresses that are at least a multiple of GCALIGNMENT.  Using
        these standard C facilities should be safer than relying on ad hoc
        and poorly-understood features like GCC’s __attribute__
        ((aligned (N))), the root cause for recent porting bugs like
        Bug#29040.  The alignas macro was standardized by C11 and Gnulib
        supports alignas for pre-C11 platforms.  I have tested this on Sun
        Studio 12 sparc (2007) and GCC 4.4.7 x86-64 (2012) as well as on
        more recent platforms like GCC 7.2.1 (2017) on Fedora 26 (both
        x86-64 and x86).
        * lib-src/make-docfile.c (close_emacs_globals): lispsym is now
        just an array of struct Lisp_Symbol, since struct Lisp_Symbol is
        now properly aligned.  All uses changed.
        * src/alloc.c (NEXT_FREE_LISP_STRING): Just use the new u.next
        member; this is simpler and safer than casting a pointer that
        might not be aligned properly.
        (aligned_Lisp_Symbol): Remove.  No longer needed, now that struct
        Lisp_Symbol is aligned properly.  All uses replaced with struct
        Lisp_Symbol.
        * src/lisp.h (GCALIGNED): Remove, as it does not work as expected:
        it can cause the natural alignment to be ignored.  All uses
        replaced by unions with a ‘char alignas (GCALIGNMENT)’ member as
        described below.
        (struct Lisp_Symbol, struct Lisp_Cons, struct Lisp_String):
        Change definition from ‘struct TAG { MEMBERS };’ to
        ‘struct TAG { union { struct { MEMBERS } s; char alignas
        (GCALIGNMENT) gcaligned; } u; };’.  This guarantees ‘struct TAG’
        to have an alignment that at least max (GCALIGNMENT, N) where N is
        its old alignment.  All uses like ‘PTR->MEMBER’ changed to
        ‘PTR->u.s.MEMBER’; these uses were supposed to be mostly private
        anyway.  Verify that the resulting ‘struct TAG’ is properly
        aligned for Emacs.
        (union vectorlike_header): New member ‘gcaligned’ to guarantee
        that this type, and its containing types like ‘struct Lisp_Subr’,
        ‘struct buffer’ and ‘struct thread_state’, are all properly
        aligned for Emacs.
        (struct Lisp_String): New union member ‘next’, for the benefit
        of NEXT_FREE_LISP_STRING.
        (union Aligned_Cons, union Aligned_String): Remove.  All uses
        replaced by struct Lisp_Cons and struct Lisp_String, since they
        are now properly aligned.
        (USE_STACK_CONS, USE_STACK_STRING): Simplify now that we can
        assume struct Lisp_Cons and struct Lisp_String are properly
        aligned.

2017-11-13  Paul Eggert  <eggert@cs.ucla.edu>

        Change vectorlike from struct to union

        * src/lisp.h (vectorlike_headed): Change from struct to union.
        All uses changed.  Since it has only one member, this does not
        change semantics.  This is designed to simplify future changes
        needed to fix bugs like Bug#29040.  All uses changed.

        Evidently nobody builds Emacs with --enable-checking=all,
        which is no surprise as it is so slow as to be unusable nowadays.

        Flymake correctly highlights whole last line if eob (bug#29201)

        If a line/column pair indicates an end-of-buffer position, flymake
        should behave like the case where the last line of the buffer is

        This fixes bug #28623.

        * lisp/progmodes/cc-engine.el (c-looking-at-or-maybe-in-bracelist): When
        testing for being enclosed in parens, recognize also a brace directly

        Enhance the return value, by indicating when we're directly inside an open
        paren.
        (c-inside-bracelist-p): Add an extra argument ACCEPT-IN-PARAM which indicates
        whether we will accept a bracelist directly inside an open parenthesis.
        Simplify the manipulation of PAREN-STATE by dispensing with variable LIM and
        using c-pull-open-brace.  Enhance the return value, respecting the new argument.
        (c-guess-basic-syntax): Save a copy of the initial parse-state in the new
        variable STATE-CACHE.  Use this variable in place of C-STATE-CACHE throughout
        the function.  At CASE 7B, call c-inside-bracelist-p with extra argument nil.

        Use GCALIGNED properly for GCC

        Apparently GCC requires that ‘__attribute__ ((aligned (8)))’ must
        immediately follow the ‘struct’ keyword when aligning a structure.
        The attribute silently does not work if it follows a tag after the
        ‘struct’ keyword.  Who knew?  Anyway, this patch is designed to
        fix a SIGSEGV problem reported by John Mastro (Bug#29183).

        Allow split-window-sensibly to split threshold in further edge case

        As a fallback, and to avoid creating a frame, split-window-sensibly
        would previously disregard split-height-threshold if the window to be
        split is the frame's root window.

        This change generalizes that: it disregards the threshold if the
        window to be split is the frame's only _usable_ window (it is either
        the only one, as before, or all the other windows are dedicated to
        some buffer and thus cannot be touched).

        This is required for the fix to bug#28814.

        * lisp/window.el (split-height-threshold): Adjust doc to match
        split-window-sensibly.
        (split-window-sensibly): Also disregard threshold if all other

        go to or show a reference is finally made.

        (xref--original-window-intent): New variable.

        Fix another "wrong side of point" error in CC Mode.

        This fixes (a follow-up to) bug #28850.
        A internal generated form for scanning text to fontify had a LIMIT parameter.
        It also locally bound LIMIT to a value possibly beyond the original LIMIT,
        allowing point to move beyond the original LIMIT, and to create the wrong side
        error.  Fix it by checking point is not beyond LIMIT in the outer context
        before using it.

        * lisp/progmodes/cc-fonts.el (c-make-font-lock-search-form): Add a new
        parameter CHECK-POINT which, when non-nil, directs the function to generate a

        Fix a "wrong side of point" error in CC Mode.  Fixes bug #28850.

        The cause was a scanning over a bracket pair taking us beyond the supplied
        LIMIT parameter in c-forward-declarator.

        * lisp/progmodes/cc-engine.el (c-forward-declarator): Add three checks (<
        (point) limit) whilst dealing with tokens after the declared identifier.

        argument to `c-forward-declarator' (twice), since we want to fontify up till

        Fix two more minor Gnus typos

        * lisp/gnus/mail-source.el (mail-source-delete-old-incoming):
        The old code had two minor bugs: first, it multiplied by 1/65536

        Be lazy when starting Flymake checks

        Don't start the check immediately if the buffer is not being
        displayed.  Wait until it is, using window-configuration-change-hook.

        This enables the user to batch-enable flymake-mode on many buffers and
        not have that operation exhaust system resources for checking each
        one.  Likewise, an editing or save operation in a currently
        non-displayed buffer does not immediately start a check.

        Speed up (format "%s" STRING) and the like

        Although the Lisp manual said that ‘format’ returns a
        newly-allocated string, this was not true for a few cases like
        (format "%s" ""), and fixing the documentation to allow reuse of
        arguments lets us improve performance in common cases like
        (format "foo") and (format "%s" "foo") (Bug#28625).
        * doc/lispref/strings.texi (Formatting Strings):
        * etc/NEWS:

        * src/editfns.c (Fmessage, Fmessage_box):
        * src/xdisp.c (vadd_to_log, Ftrace_to_stderr):
        Just use Fformat or Fformat_message, as that’s simpler and no
        longer makes unnecessary copies.
        * src/editfns.c (styled_format): Remove last argument, as it
        is no longer needed: all callers now want it to behave as if it
        were true.  All remaining callers changed.  Make this function
        static again.  Simplify the function now that we no longer
        need to worry about whether the optimization is allowed.

        Fontify untyped function declarations in C Mode correctly.

        Also correct two bugs where deleting WS at a BOL could leave an untyped
        function declaration unfontified.

        * lisp/progmodes/cc-engine.el (c-find-decl-spots): Don't set the flag
        "top-level" when we're in a macro.
        (c-forward-decl-or-cast-1): Recognize top-level "foo(bar)" or "foo()" in C
        Mode as a implicitly typed function declaration.
        (c-just-after-func-arglist-p): Don't get confused by "defined (foo)" inside a
        macro.  It's not a function plus arglist.

        * lisp/progmodes/cc-langs.el (c-cpp-expr-functions-key): New defconst and
        defvar.

        * lisp/progmodes/cc-mode.el (c-fl-decl-end): After c-forward-declarator, move

        The interfaces in bytecomp.el and checkdoc.el are mostly boilerplate,

        Flymake backends can report multiple times per check

        Rewrote a significant part of the Flymake backend API.  Flymake now
        ignores the return value of backend functions: a function can either
        returns or errors.  If it doesn't error, a backend is no longer
        constrained to call REPORT-FN exactly once.  It may do so any number
        of times, cumulatively reporting diagnostics.  Flymake keeps track of
        outdated REPORT-FN instances and disconsiders obsolete reports.
        Backends should avoid reporting obsolete data by canceling any
        ongoing processing at every renewed call to the backend function.

        Consolidated flymake.el internal data structures to require less
        buffer-local variables.  Adjusted Flymake's mode-line indicator to the
        new semantics.

        Adapted and simplified the implementation of elisp and legacy
        backends, fixing potential race conditions when calling backends in
        rapid succession.

        Added a new test for a backend that calls REPORT-FN multiple
        times.  Simplify test infrastructure.

        * lisp/progmodes/flymake-elisp.el (flymake-elisp-checkdoc)
        (flymake-elisp-byte-compile): Error instead of returning nil
        if not in emacs-lisp-mode.

        obsolete process.

2017-10-03  João Távora  <joaotavora@gmail.com>

        Fix three Flymake bugs when checking C header files

        The first of these problems is longstanding: if an error-less B.h is
        included from error-ridden A.h, flymake's legacy parser will panic
        (and disable itself) since it sees a non-zero exit for a clean file.
        To fix this, recommend returning 'true' in the documentation for the
        check-syntax target.

        Another problem was introduced by the parser rewrite.  For error
        patterns spanning more than one line, point may be left in the middle
        of a line and thus render other patterns useless.  Those patterns were
        written for the old line-by-line parser.  To make them useful again,
        move to the beginning of line in those situations.

        The third problem was also longstanding and happened on newer GCC's:
        The "In file included from" prefix confused
        flymake-proc-get-real-file-name.  Fix this.

        Also updated flymake--diag-region to fallback to highlighting a full
        line less often.

        Add automatic tests to check this.

        A couple of Flymake backends for emacs-lisp-mode

        Loading flymake-elisp.el doesn't setup flymake-mode to turn on
        automatically, but it affects emacs-lisp-mode-hook so that
        flymake-diagnostic-functions is setup with a suitable buffer-local

        Tweak Flymake commands flymake-goto-[next/prev]-error

        Add filters, useful for backends like the upcoming
        flymake-elisp-checkdoc backend, for example, which litters everything
        with low-priority notes.

        Also re-implement wraparound for flymake-goto-next-error. Manual

        Simplify Flymake logging and erroring

        Use display-warning and a dedicated *Flymake log* buffer.

        To ease readability, flymake log messages are now prefixed with a
        common prefix and the buffer that originated them.

        Some situations of over-zealous logging are fixed.

        New Flymake API variable flymake-diagnostic-functions

        Lay groundwork for multiple active backends in the same buffer.

        Backends are lisp functions called when flymake-mode sees fit.  They
        are responsible for examining the current buffer and telling
        flymake.el, via return value, if they can syntax check it.
        Backends should return quickly and inexpensively, but they are also
        passed a REPORT-FN argument which they may or may not call
        asynchronously after performing more expensive work.

        REPORT-FN's calling convention stipulates that a backend calls it with
        a list of diagnostics as argument, or, alternatively, with a symbol
        denoting an exceptional situation, usually some panic resulting from a
        misconfigured backend.  In keeping with legacy behavior,
        flymake.el's response to a panic is to disable the issuing backend.

        The flymake--diag object representing a diagnostic now also keeps
        information about its source backend.  Among other uses, this allows
        flymake to selectively cleanup overlays based on which backend is
        updating its diagnostics.

        * lisp/progmodes/flymake-proc.el (flymake-proc--report-fn):
        New dynamic variable.

        More Flymake cleanup before advancing to backend redesign

        Diagnostics are reported for buffers, not necessarily files.  It’s the
        backend’s responsibility to compute the buffer where the diagnostic is
        applicable.  For now, this has to match the buffer where flymake-mode
        is active and which is at the origin of the backend call.

        flymake.el knows nothing about line/column diagnostics (except for
        backward-compatible flymake-ler-make-ler, which must yet be tested).
        It’s also the backend’s responsibility to compute a BEG and END
        positions for the diagnostic in the relevant buffer.

        * lisp/progmodes/flymake-proc.el
        (flymake-proc--diagnostics-for-pattern): Convert LINE/COL to
        region here.  Check file buffer here.
        (flymake-proc--process-sentinel): Don’t kill output buffer if
        high enough log level.

        * lisp/progmodes/flymake.el (flymake-diag-region): Make this a utility
        function.  (flymake--highlight-line): Diagnostic has region now.
        (flymake-popup-current-error-menu): Don’t add file and line numbers to
        already this silly menu.  (flymake--fix-line-numbers): Remove.
        (flymake-report): No need to fix diagnostics here.

        Protect Flymake's eager checks against commands like fill-paragraph

        If flymake-start-syntax-check-on-newline is t, check should start as
        soon as a newline is seen by after-change-functions.  But don't rush
        it: since the buffer state might not be final, we might end up with
        invalid diagnostic regions after some commands silently insert and
        delete newlines (looking at you, fill-paragraph).

        * lisp/progmodes/flymake.el (flymake-after-change-function): Pass
        `deferred' to flymake--start-syntax-check.

        Flymake checks file names before considering diagnostics

        Flymake's flymake-proc.el parses column numbers from gcc/javac errors

        Column numbers are not a great way of marking diagnostic regions, but
        that's probably all that can be expected from the flymake-proc.el
        backend.  For now, try (end-of-thing 'sexp) to discover the
        diagnostic's end position.

        * lisp/progmodes/flymake-proc.el ()
        (flymake-proc-err-line-patterns): Also parse column numbers,

2017-10-03  João Távora  <joaotavora@gmail.com>

        New Flymake variable flymake-diagnostic-types-alist and much cleanup

        A new user-visible variable is introduced where different diagnostic
        types can be categorized.  Flymake backends can also contribute to
        this variable.  Anything that doesn’t match an existing error type
        is considered.

        The variable’s alists are used to propertize the overlays pertaining
        to each error type.  The user can override the built-in properties by
        either by modifying the alist, or by modifying the properties of a
        special "category" symbol, named by the `flymake-category' entry in
        the alist.

        The `flymake-category' entry is especially useful for, say, the author
        of foo-flymake-backend, who issues diagnostics of type :foo-note, that
        should behave like notes, except with no fringe bitmap:

           (add-to-list 'flymake-diagnostic-types-alist
                        '(:foo-note
                          . ((flymake-category . flymake-note)
                             (bitmap . nil))))

        For essential properties like `severity', `priority', etc, a default
        value is produced.  Some properties like `evaporate' cannot be
        overridden.

        * lisp/progmodes/flymake.el (flymake--diag): Rename from
        flymake-ler.

        Flymake diagnostics now apply to arbitrary buffer regions

        Make Flymake UI some 150 lines lighter

        Strip away much of the original implementation's complexity in
        manipulating objects representing diagnostics as well as creating and
        navigating overlays.

        Lay some groundwork for a more flexible approach that allows for
        different classes of diagnostics, not necessarily line-based.
        Importantly, one overlay per diagnostic is created, whereas the
        original implementation had one per line, and on it it concatenated
        the results of errors and warnings.

        This means that currently, an error and warning on the same line are
        problematic and the warning might be overlooked but this will soon be
        fixed by setting appropriate priorities.

        Since diagnostics can highlight arbitrary regions, not just lines, the
        faces were renamed.

        Tests pass and backward compatibility with interactive functions is
        maintained, but probably any third-party extension or customization
        relying on more than a trivial set of flymake.el internals has stopped
        working.

        * lisp/progmodes/flymake-proc.el
        (flymake-proc--diagnostics-for-pattern): Use new flymake-ler-make
        constructor syntax.

        Move symbols in flymake-proc.el to separate namespace

        Every symbol in this flymake now starts with the prefix flymake-proc-.

        Make obsolete aliases for (almost?) every symbol.

        Furthermore, many flymake-proc.el symbols are prefixed with
        "flymake-proc--", that is they were considered internal.

        Some customization variables, interactive functions, and other symbols
        considered useful to user customizations or third-party libraries are
        considered "public" or "external" and so use a "flymake-proc-" prefix.

        * lisp/progmodes/flymake-proc.el: Every symbol renamed.

        * test/lisp/progmodes/flymake-tests.el
        (flymake-tests--current-face): Use

        Completely rewrite Flymake's subprocess output processing

        Instead of parsing and matching regexps line-by-line, insert
        subprocess output in a separate buffer and parse using
        `search-forward-regexp'.  This eventually enables multi-line error
        patterns and simplifies code all around.  Store per-check information
        in the subprocess using `process-get' and `process-put'.  Treat error
        messages, warnings, etc. more generically as "diagnostics".  Create
        these objects as soon as possible, reusing existing `flymake-ler'
        structure.  Fix some whitespace.

        * lisp/progmodes/flymake.el (cl-lib): Require also when
        loading.
        (flymake--fix-line-numbers): Rename from

        * lisp/progmodes/flymake-proc.el (flymake-process-filter): Insert
        process output and parse in dedicated output buffer.
        (flymake-proc--diagnostics-for-pattern): New helper function.

        Split Flymake into flymake.el into flymake-proc.el (again!)

        After deciding that this work would continue on master only, which
        caused two commits named

           Revert "Split flymake.el into flymake-proc.el and flymake-ui.el"

        and

           Revert "Add flymake-backends defcustom"

        to be added to the emacs-26 branch, further discussion reversed that
        decision.

           See:

             https://lists.gnu.org/r/emacs-devel/2017-09/msg01020.html
             https://lists.gnu.org/r/emacs-devel/2017-09/msg01030.html

        This means that those two commits MUST be merged to master AFTER ALL.

        flymke-proc.el contains the main syntax-checking backend, while
        flymake.el keeps mostly the UI part.

        * lisp/progmodes/flymake-proc.el: New file.  Require flymake.

        * lisp/progmodes/flymake.el: Require flymake-proc.el at the end.

        Avoid some unnecessary copying in Fformat etc.

        On my platform, it made the microbenchmark (format "%S" load-path)

        * lisp/calendar/cal-tex.el (cal-tex-preamble): Make 12pt the
        default class option.

        request to `cal-tex-insert-preamble' function call within the
        class option string.
        (cal-tex-cursor-month): Don't pass any longer "12pt" argument
        to `cal-tex-insert-preamble' function, as it is default.
        (cal-tex-insert-preamble): Suppress landscape and size
        argument, and replace them by a class-options string
        argument. Do not insert any longer "\special{landscape}" in
        case of landscape layout, as the job is made by the geometry
        package.

        eassert, to avoid compilation warnings about NULL pointer
        dereferences.

2017-09-15  Mark Oteiza  <mvoteiza@udel.edu>

        More JSON optimization

        Last I checked, inlining json-skip-whitespace didn't make much
        difference.  However, changing defsubsts to define-inline results
        in roughly 15% reduction in read time on a 200K file.
        * lisp/json.el (json-advance, json-peek, json-pop):
        (json-skip-whitespace): Inline with define-inline.
        (json-read-keyword): Don't use whitespace syntax.
        (json-add-to-object): Simpler condition.

        Prefer HTTPS to FTP and HTTP in documentation

        Most of this change is to boilerplate commentary such as license URLs.
        This change was prompted by ftp://ftp.gnu.org's going-away party,
        planned for November.  Change these FTP URLs to https://ftp.gnu.org
        instead.  Make similar changes for URLs to other organizations moving
        away from FTP.  Also, change HTTP to HTTPS for URLs to gnu.org and
        fsf.org when this works, as this will further help defend against
        man-in-the-middle attacks (for this part I omitted the MS-DOS and
        MS-Windows sources and the test tarballs to keep the workload down).
        HTTPS is not fully working to lists.gnu.org so I left those URLs alone
        for now.

2017-09-14  Paul Eggert  <eggert@cs.ucla.edu>

        Prefer HTTPS to HTTP for gnu.org

        This patch just changes code files; a followup companion patch
        (much larger) will affect the commentary.  This part is

        Remove "baroque" use of prefix argument from gensym

        shed some historical baggage.
        * lisp/subr.el (gensym): Remove special treatment of PREFIX as a

        Bug#28412

        * lisp/files.el (basic-save-buffer): Re-arrange function so that
          write-contents-functions are run earlier. If they return non-nil,
          consider the buffer saved without requiring the buffer to be
          visiting a file.
          (save-some-buffers): This function should consider any buffer with a

2017-09-12  Mark Oteiza  <mvoteiza@udel.edu>

        Implement and-let*

        This also includes changes to if-let and when-let.  The single tuple
        special case is ambiguous, and binding a symbol to nil is not as
        useful as binding it to its value outside the lexical scope of the
        binding.  (Bug#28254)

        * lisp/emacs-lisp/subr-x.el (internal--listify):
        (internal--build-binding-value-form): Extend to account for
        solitary symbols and (EXPR) items in binding varlist.
        (if-let*, when-let*): Nix single tuple case and incumbent
        bind-symbol-to-nil behavior.
        (and-let*): New macro.
        (if-let, when-let): Mark obsolete.  Redefine in terms of if-let*, so
        they implicitly gain the new features without breaking existing code.
        * test/lisp/emacs-lisp/subr-x-tests.el: Adjust tests for: lack of
        single-tuple special case, lack of binding solitary symbols to nil,
        and the introduction of uninterned symbols for (EXPR) bindings.  Add
        SRFI-2 test suite adapted to Elisp.

2017-09-11  Paul Eggert  <eggert@cs.ucla.edu>

        Fix race with rename-file etc. with dir NEWNAME

        This changes the behavior of rename-file etc. slightly.
        The old behavior mostly disagreed with the documentation, and had
        a race condition bug that could allow attackers to modify victims'
        write-protected directories (Bug#27986).

2017-09-09  Paul Eggert  <eggert@cs.ucla.edu>

        Improve --enable-gcc-warnings for MinGW64

        This partially reverts my 2016-05-30 patch.  Apparently MinGW64
        still requires pacifications that GCC 7.1.1 x86-64 (Fedora 26)
        does not.  Also, pacify tparam.c, which isn’t used on Fedora.

        (internal_lisp_condition_case): Use it.
        * src/tparam.c (tparam1): Use FALLTHROUGH to pacify GCC.

        * lisp/net/rcirc.el (rcirc-markup-urls): Use `make-text-button'
        instead of `make-button'; the former is much more efficient in large

        Be more conservative in link time optimization doc

        While testing --enable-link-time-optimization with GCC 7.1.1
        I ran into a serious GCC code-generation bug which makes me
        think that --enable-link-time-optimization should be
        discouraged for typical installs (Bug#28213).  See:
        https://bugzilla.redhat.com/show_bug.cgi?id=1486455

2017-08-29  Paul Eggert  <eggert@cs.ucla.edu>

        Make garbage collection more conservative

        Check for a pointer anywhere within the object, as opposed to just
        the start of the object.  This is needed for gcc -Os -flto on
        x86-64 (Bug#28213).  This change means that the garbage collector
        is more conservative, and will incorrectly keep objects that it
        does not need to, but that is better than incorrectly discarding
        objects that should be kept.
        * src/alloc.c (ADVANCE, VINDEX): Now functions, not macros;
        this is easier to debug.
        (setup_on_free_list): Rename from SETUP_ON_FREE_LIST.
        Now a function with two args, not a macro with three.
        All callers changed.
        (live_string_holding, live_cons_holding, live_symbol_holding)
        (live_misc_holding, live_vector_holding, live_buffer_holding):
        New functions, which check for any object containing the addressed
        byte, not just for an object at the given address.
        (live_string_p, live_cons_p, live_symbol_p, live_misc_p)
        (live_vector_p, live_buffer_p):
        Redefine in terms of the new functions.
        (live_float_p): Refactor slightly to match the new functions.
        (mark_maybe_object, mark_maybe_pointer): Use the new functions.
        Don’t bother checking mark bits, as mark_object already does that,
        and omitting the checks here simplifies the code.  Although
        mark_maybe_object can continue to insist that tagged pointers
        still address the start of the object, mark_maybe_pointer now is
        more conservative and checks for pointers anywhere into an object.

2017-08-29  Paul Eggert  <eggert@cs.ucla.edu>

        Improve stack-top heuristic

        This is needed for gcc -Os -flto on x86-64; otherwise, GC misses part
        of the stack when scanning for heap roots, causing Emacs to crash
        later (Bug#28213).  The problem is that Emacs's hack for getting an
        address near the stack top does not work when link-time optimization
        moves stack variables around.
        * configure.ac (HAVE___BUILTIN_FRAME_ADDRESS): New macro.
        * lib-src/make-docfile.c (DEFUN_noinline): New constant.
        (write_globals, scan_c_stream): Support noinline.

        Disable completion while entering python multiline statements

        Amend the CC Mode macro cache to cope with changes at the macro start

        Fixes bug #28233.

        error.

2017-08-27  Paul Eggert  <eggert@cs.ucla.edu>

        Fix over-protection of byte-compiled files

        Problem reported by Sven Joachim (Bug#28244).
        Also, fix similar problem for autoload files.
        * lisp/emacs-lisp/autoload.el (autoload--save-buffer):
        Set temp file modes to the buffer-file-name file modes (or 666
        if not available) as adjusted by umask.
        * lisp/emacs-lisp/bytecomp.el (byte-compile-file):
        Set temp file modes to 666 as adjusted by umask.

        Bug#28218
        * lisp/textmodes/conf-mode.el (conf-toml-font-lock-keywords): Use
        conf-toml-recognize-section.  Use \s- in variable regexp.
        (conf-toml-recognize-section): New function.

2017-08-27  Paul Eggert  <eggert@cs.ucla.edu>

        Do not munge contents of local symbolic links

        This lets Emacs deal with arbitrary local symlinks without
        mishandling their contents (Bug#28156).  For example,
        (progn (shell-command "ln -fs '~' 'x'") (rename-file "x" "/tmp/x"))
        now consistently creates a symbolic link from '/tmp/x' to '~'.
        Formerly, it did that only if the working directory was on the
        same filesystem as /tmp; otherwise, it expanded the '~' to
        the user's home directory.
        * lisp/dired.el (dired-get-filename): Use files--name-absolute-system-p
        instead of rolling our own code.
        * lisp/files.el (files--name-absolute-system-p): New function.
        (file-truename, file-chase-links): Use it to avoid mishandling
        symlink contents that begin with ~.
        (copy-directory, move-file-to-trash):
        Use concat rather than expand-file-name, to avoid mishandling
        symlink contents that begin with ~.
        * src/fileio.c (Fmake_symbolic_link): Do not expand leading "~" in the
        target unless interactive.  Strip leading "/:" if interactive.
        (emacs_readlinkat): Do not prepend "/:" to the link target if
        it starts with "/" and contains ":" before NUL.
        * test/src/fileio-tests.el (try-link): Rename from try-char,
        and accept a string instead of a char.  All uses changed.
        (fileio-tests--symlink-failure): Also test leading ~, and "/:",
        to test the new behavior.

2017-08-27  Reuben Thomas  <rrt@sc3d.org>

        Remove invalid regexp for shell builtins for wksh

        * lisp/progmodes/sh-script.el (sh-builtins): Shell built-ins have to
        be literal strings, so remove a regexp for wksh. In any case, it’s a
        defunct proprietary shell.

        Fix Tramp part of Bug#28156

        * lisp/files.el (file-name-non-special): Use `file-name-quote'

        * lisp/net/tramp.el (tramp-error): Handle null arguments.
        (tramp-handle-make-symbolic-link):
        * lisp/net/tramp-sh.el (tramp-sh-handle-make-symbolic-link)

        * lisp/net/tramp-smb.el (tramp-smb-handle-add-name-to-file)
        (tramp-smb-handle-make-symbolic-link): Adapt implementation to
        stronger semantics in Emacs.  (Bug#28156)

        * test/lisp/net/tramp-tests.el (tramp-test21-file-links):
        Extend test.

        section detection in several langages: French, German, Spanish,
        Portuguese, Italian, Polish, Turkish, Japanese, Chinese.  (Bug#28142)

2017-08-26  Paul Eggert  <eggert@cs.ucla.edu>

        Improve expand-file-name doc

        * doc/lispref/files.texi (Relative File Names, Directory Names)
        (File Name Expansion):
        * doc/lispref/minibuf.texi (Reading File Names):
        Document expand-file-name behavior with ~ more clearly
        and accurately.
        * doc/misc/org.texi (Batch execution): Simplify example
        script so that it does not need expand-file-name and thus
        will not mishandle file names with leading ~.

2017-08-26  Jefferson Carpenter  <jeffersoncarpenter2@gmail.com>  (tiny change)

        Support all perl variable declarators and prefixes (Bug#27613)

        Fix file-attributes race on GNU hosts

        * doc/lispref/files.texi (File Attributes):
        Document file-attributes atomicity.
        * etc/NEWS: Document the fix.
        * src/dired.c (file_attributes): New args DIRNAME and FILENAME,
        for diagnostics.  All callers changed.  On platforms like
        GNU/Linux that support O_PATH, fix a race condition in
        file-attributes and similar functions, so that these functions do
        not return nonsense if a directory entry is replaced while getting
        its attributes.  On non-GNU platforms, do a better (though not
        perfect) job of detecting the race, and return nil if detected.

2017-08-25  Paul Eggert  <eggert@cs.ucla.edu>

        Simplify expand_and_dir_to_file

        * src/fileio.c (expand_and_dir_to_file): Simplify by omitting 2nd
        argument, since in practice it always has the default value.  All
        callers changed.  Prefer C99 style decls in nearby code.

2017-08-25  Eli Zaretskii  <eliz@gnu.org>

        Fix file-name completion on network shares

        * src/w32.c (faccessat): Don't assume that F_OK is non-zero.

        Fix a FIXME with an exegetical comment

        * lisp/progmodes/sh-script.el (sh-builtins): Explain why we have a

2017-08-25  Reuben Thomas  <rrt@sc3d.org>

        Minor docstring language fix

2017-08-25  Reuben Thomas  <rrt@sc3d.org>

        Remove old commented code from sh-script.el

        * lisp/progmodes/sh-script.el (sh-abbrevs): Remove commented function
        and variable, commented since 2001.

2017-08-25  Stefan Monnier  <monnier@iro.umontreal.ca>

        * lisp/emacs-lisp/package.el: Don't let failure stop us

        (package-activate-1): Don't throw an error for missing deps.
        (package-unpack): Don't bother compiling if activation failed.
        (package-initialize): Report failures but keep activating other packages.

2017-08-25  Paul Eggert  <eggert@cs.ucla.edu>

        (x_set_toolkit_scroll_bar_thumb)
        (x_set_toolkit_horizontal_scroll_bar_thumb): Prefer ‘double’ to
        ‘float’ for individual local floating-point temporaries.

2017-08-24  Reuben Thomas  <rrt@sc3d.org>

        Avoid using string-to-multibyte in ispell.el

        * lisp/textmodes/ispell.el (ispell-get-decoded-string): Use
        decode-coding-string instead. Note that decode-coding-string returns a
        string that satisfies multibyte-string-p even if its input is pure
        ASCII and the third argument is t, so the result of
        ispell-get-decoded-string is always a multibyte string.

2017-08-24  Tino Calancha  <tino.calancha@gmail.com>

        Store the regexp just when there are matches

        * lisp/hi-lock.el (hi-lock-set-pattern): When font-lock-mode is
        disabled and there are no matches do not store REGEXP
        in hi-lock-interactive-patterns.

2017-08-24  Tino Calancha  <tino.calancha@gmail.com>

        Keep face available if there are no matches

        If font-lock-mode is disabled in the current buffer, and
        there are no matches for REGEXP, then keep FACE available
        for a next search.
        * lisp/hi-lock.el (hi-lock-set-pattern): Add FACE into
        hi-lock--unused-faces if font-lock-mode is disabled and
        there are no matches.
        * test/lisp/hi-lock-tests.el (hi-lock-test-set-pattern): Add test.

        Remove old commented code and obsolete comments

        * lisp/files.el (locate-dominating-files): Remove old commented
        implementation from 9 years ago.  Since the current version
        appears (at least to me) not just more efficient but clearer than the
        version removed, also delete a comment in the new version referring to
        the old version. Remove old commented heuristic code,
        and explanatory comments.

2017-08-24  Reuben Thomas  <rrt@sc3d.org>

        Remove old duplicate commented code

        * lisp/files.el (file-relative-name): Remove old commented version,

        options.
        * src/frame.h (ns_appearance_type) [NS_IMPL_COCOA]: Add enum to

        When looking for the end of a declarator, prevent macros fouling up the search

        The practical implication of this bug was a random jit-lock chunk remaining
        entirely unfontified.

        * lisp/progmodes/cc-mode.el (c-fl-decl-end): If point starts inside a macro,
        restrict two forward searches to the end of that macro.

2017-08-22  Noam Postavsky  <npostavs@gmail.com>

        Optimize skkdic conversion (Bug#28043)

        The primary speedup comes from the optimizing lookup-nested-alist and
        set-nested-alist for the case where the key is a string.  This brings
        the time down to less than half the original.

        * lisp/international/mule-util.el (lookup-nested-alist)
        (set-nested-alist): Use `assq' instead of `assoc' when KEYSEQ is a
        string.

        * lisp/international/ja-dic-cnv.el (skkdic-collect-okuri-nasi)
        (skkdic-convert-okuri-nasi): Use progress-reporter functions instead
        of calculating ratio of work done inline.

        (skkdic-reduced-candidates): Call `char-category-set' on the first
        character of the string directly, instead of using a regexp for the
        character category.
        (skkdic--japanese-category-set): New constant.
        (skkdic-collect-okuri-nasi): Just set
        `skkdic-okuri-nasi-entries-count' at once at the end rather than
        updating it throughout the loop.

        (skkdic-convert-postfix skkdic-convert-prefix)
        skkdic-get-candidate-list, skkdic-collect-okuri-nasi)
        (skkdic-extract-conversion-data): Use `match-string-no-properties'
        instead of `match-string'.

        Do not assume regular Git .git/hooks dir

        Apparently Gitlab doesn’t create .git/hooks, like regular Git does.
        Problem reported by Ted Zlatanov in:

        New manual section "Copying and Naming"

        * doc/emacs/files.texi (Copying and Naming):
        New section, split off from Misc File Ops and containing the
        operations that copy, name or rename files.  This fixes some
        confusion caused by the incorrect phrase "The same rule applies
        to all the remaining commands in this section" in the old manual.
        This change does not affect the confusion about directories (see
        Bug#27986 for ongoing discussion).

        Fix make-temp-file bug with ""/"."/".." prefix

        The bug with "." and ".." has been present for a while; I
        introduced the bug with "" earlier today in my patch for Bug#28023.
        * lisp/files.el (make-temp-file): Do not use expand-file-name if
        PREFIX is empty or "." or "..", as it does the wrong thing.
        Compute absolute-prefix here ...
        (files--make-magic-temp-file): ... instead of here ...
        * src/fileio.c (Fmake_temp_file_internal): ... or here.

        * lisp/files.el (make-temp-file): If the prefix is empty, append
        "/" to the absolute prefix so that the new files are children
        rather than siblings of temporary-file-directory.  This fixes a
        bug introduced in the previous change.
        * test/lisp/files-tests.el (files-test-make-temp-file-empty-prefix):
        New test, for the bug.

2017-08-13  Paul Eggert  <eggert@cs.ucla.edu>

        Improve make-temp-file performance on local files

        For the motivation behind this patch, please see Bug#28023 and:
        https://emacshorrors.com/posts/make-temp-name.html
        Although, given the recent changes to Tramp, the related security
        problem in make-temp-file is already fixed, make-temp-file still has
        several unnecessary system calls.  In the typical case on GNU/Linux,
        this patch replaces 8 syscalls (symlink, open, close, readlinkat, uname,
        getpid, unlink, umask) by 2 (open, close).
        * admin/merge-gnulib (GNULIB_MODULES): Add tempname, now
        that Emacs is using it directly.
        * configure.ac (AUTO_DEPEND): Remove AC_SYS_LONG_FILE_NAMES;
        no longer needed.
        * lib/gnulib.mk.in, m4/gnulib-comp.m4: Regenerate.
        * lisp/files.el (files--make-magic-temp-file): Rename from
        make-temp-file.
        (make-temp-file): Use make-temp-file-internal for
        non-magic file names.
        * src/fileio.c: Include tempname.h.
        (make_temp_name_tbl, make_temp_name_count)
        (make_temp_name_count_initialized_p, make_temp_name): Remove.
        (Fmake_temp_file_internal): New function.
        (Fmake_temp_name): Use it.
        * src/filelock.c (get_boot_time): Use Fmake_temp_file_internal
        instead of make_temp_name.

        * README: Mention autoconf.sh's effect on Git configuration.

2017-08-12  Paul Eggert  <eggert@cs.ucla.edu>

        Default autogen.sh to 'all'

        This addresses a problem noted by RMS in:
        https://lists.gnu.org/r/emacs-devel/2017-08/msg00052.html
        * autogen.sh (do_git): Set to true if this script is invoked
        with no arguments and there is a .git subdirectory.

        Fix completion on directory names on MS-DOS/MS-Windows

        * src/msdos.c (faccessat):
        * src/w32.c (faccessat): Support relative file names, and add D_OK
        to 'mode' if the argument is a directory.  This unbreaks file-name
        completion when the completion result is a directory.

2017-08-11  Stephen Berman  <steve@rosalinde.fritz.box>

        Fix a minor todo-mode regression

        * lisp/calendar/todo-mode.el (todo-get-overlay): Wrap in
        save-excursion.  This fixes a regression introduced by the fix
        for bug#27609, whereby trying to raise the priority of the
        first item or lower the priority of the last item, which
        should be noops, moves point to the item's start.  Clarify
        comment.

        * test/lisp/calendar/todo-mode-tests.el
        (todo-test-raise-lower-priority): Add test cases for trying to
        raise first item and lower last item.
        (with-todo-test): Clear abbreviated-home-dir, since we change HOME.
        (todo-test-toggle-item-header02): Remove ":expected-result
        :failed" and tests of point after todo-next-item, since the
        effect when using Todo mode is not reproducible in the test
        environment.  Add commentary about this.

        Although this does not fix Bug#27986, it is a step forward.
        I plan to propose a more-significant patch later.
        * lisp/files.el (directory-name-p): Move from here ...
        * src/fileio.c (Fdirectory_name_p): ... to here.
        (directory_like, cp_like_target): New static functions.
        (Fcopy_file, Frename_file, Fadd_name_to_file)
        (Fmake_symbolic_link):
        Use them, to avoid directory-testing syscalls on file names that
        must be directories if they exist.  Omit unnecessary
        initializations and CHECK_STRING calls.
        (Frename_file): Don't call file_name_case_insensitive_p
        twice on the same file.  Compare both file names expanded, instead
        of the old name expanded and the new one unexpanded.

        (ispell-check-version): If using Enchant, check it’s new enough (at

        without.)
        (ispell-enchant-dictionary-alist): Add variable.
        (ispell-find-enchant-dictionaries): Add function, based on
        ispell-find-aspell-dictionaries.

        Fix some crashes on self-modifying Elisp code

        Prompted by a problem report by Alex in:
        https://lists.gnu.org/r/emacs-devel/2017-08/msg00143.html
        * src/eval.c (For, Fprogn, Fsetq, FletX, eval_sub):
        Compute XCDR (x) near XCAR (x); although this doesn't fix any bugs,
        it is likely to run a bit faster with typical hardware caches.
        (Fif): Use Fcdr instead of XCDR, to avoid crashing on
        self-modifying S-expressions.
        (Fsetq, Flet, eval_sub): Count the number of arguments as we go
        instead of trusting an Flength prepass, to avoid problems when the
        code is self-modifying.
        (Fquote, Ffunction, Fdefvar, Fdefconst): Prefer !NILP to CONSP
        where either will do.  This is mostly to document the fact that
        the value must be a proper list.  It's also a tiny bit faster on
        typical machines nowadays.
        (Fdefconst, FletX): Prefer XCAR+XCDR to Fcar+Fcdr when either will do.
        (eval_sub): Check that the args are a list as opposed to some
        other object that has a length. This prevents e.g. (if . "string")
        from making Emacs dump core in some cases.
        * test/src/eval-tests.el (eval-tests--if-dot-string)
        (eval-tests--let-with-circular-defs, eval-tests--mutating-cond):

        dired-delete-file: Do not TAB complete the user answer

        This action might delete directories containing valuable information.
        Before previous commit, we prompted users with `yes-or-no-p'
        which doesn't TAB complete the user answer.  Let's play safe and
        keep requiring full answers.

        dired-do-delete: Allow to delete dirs recursively without prompts

        * lisp/dired.el (dired-delete-file): Accept 2 additional answers:
        'all', to delete all directories recursively and no prompt anymore.
        'quit', to cancel directory deletions (Bug#27940).
        Show help message when user inputs 'help'.
        (dired-do-flagged-delete): Bind locally dired-recursive-deletes
        so that we can overwrite its global value.
        Wrap the loop within a catch '--delete-cancel to catch when
        the user abort the directtry deletion.

        Use make-temp-file, not make-temp-name, to avoid an unlikely race
        that could lose data.  Remove the deletion hook as quickly as
        possible after the file is renamed; though a race still remains

        Instead, line numbers are invariant under shrinks/enlargements

2017-08-05  Eli Zaretskii  <eliz@gnu.org>

        Fix a bug in 'generate-new-buffer-name'

        * src/buffer.c (Fgenerate_new_buffer_name): Test IGNORE for being

        ls-lisp: Drop eshell dependencies

        Use 'file-expand-wildcards' instead of 'eshell-extended-glob' to
        expand the wildcards.
        Suggested by Fabrice Popineau in:
        https://lists.gnu.org/r/emacs-devel/2017-08/msg00108.html
        * lisp/ls-lisp.el (ls-lisp--dired): Use file-expand-wildcards.

        Fix dired-test-bug27631 on MS-Windows

        Skip the test if Dired use 'ls' emulation with lisp.  The same
        bug is tested in their respective test suites: ls-lisp-tests.el
        and em-ls-tests.el.
        * test/lisp/dired-tests.el (dired-test-bug27631): Skip test if 'ls-lisp'

        * test/lisp/dired-tests.el (dired-test-bug25609): On MS-Windows,
        pass temporary files through file-truename, to avoid bogus
        failures due to file-name comparison as strings.

2017-08-04  Tino Calancha  <tino.calancha@gmail.com>

        Fix 2 tests that fail in MS-Windows

        https://lists.gnu.org/r/emacs-devel/2017-08/msg00018.html
        * test/lisp/vc/ediff-ptch-tests.el (ediff-ptch-test-bug26084):
        Add comments to explain the test logic.
        Pass '--binary' option to 'patch' program in windows environments.
        Check explicitly that a backup is created before compare file contents.

        * test/lisp/dired-tests.el (dired-test-bug25609):
        Declare variable 'dired-dwim-target' right before the test.
        Add comments to explain the test logic.
        Ensure, before test the bug condition, that we are displaying the
        2 dired buffers created in this test, and no other dired buffer
        is shown.

2017-08-04  Stefan Monnier  <monnier@iro.umontreal.ca>

        Fix version numbers for some GnuTLS features

        Problem reported by Glenn Morris (Bug#27708#58).
        * src/gnutls.c (HAVE_GNUTLS_X509_SYSTEM_TRUST):
        New macro.  Use it instead of low-level version number checks.
        (HAVE_GNUTLS_AEAD): Move here from gnutls.h, and rename from
        HAVE_GNUTLS3_AEAD.  All uses changed.  Indent preprocessor lines.
        * src/gnutls.h (HAVE_GNUTLS3_CIPHER, HAVE_GNUTLS3_DIGEST)
        (HAVE_GNUTLS3_HMAC): Remove, since these were available
        before GnuTLS 3.0.0 and the code checks them only if HAVE_GNUTLS3
        is defined.  Remove all uses; this simplifies the code a bit.

2017-08-04  Paul Eggert  <eggert@cs.ucla.edu>

        Port recent rename changes to RHEL 7 + NFS

        Problem reported by Ted Zlatanov in:
        https://lists.gnu.org/r/emacs-devel/2017-08/msg00082.html
        * src/fileio.c (Frename_file): On RHEL 7 + NFS, renameat2 can fail
        with errno == EINVAL when it is not supported.  So treat that case
        like errno == ENOSYS.  Also, when ok_if_already_exists is neither
        nil nor an integer, just call plain rename; this avoids an extra
        syscall to renameat2 when the latter fails with errno == EINVAL or
        ENOSYS or ENOENT.

2017-08-03  Paul Eggert  <eggert@cs.ucla.edu>

        Port GnuTLS usage to Ubuntu 16.04.2 LTS

        * src/gnutls.h (HAVE_GNUTLS3_AEAD): Define only if GnuTLS 3.5.1 or
        later, as opposed to the old 3.4.0 or later.

2017-08-03  Paul Eggert  <eggert@cs.ucla.edu>

        Simplify configuration of HAVE_GNUTLS3 etc.

        There's only one GnuTLS, so configuring these symbols at
        'configure' time is overkill.  Simplify things by moving their
        configuration to src/gnutls.h (Bug#27708).
        * configure.ac (HAVE_GNUTLS3, HAVE_GNUTLS3_HMAC, HAVE_GNUTLS3_AEAD)
        (HAVE_GNUTLS3_CIPHER, HAVE_GNUTLS3_DIGEST): Move these definitions
        from here ...
        * src/gnutls.h: ... to here, and simplify.

        * Makefile.in (configure, bootstrap): Run ‘./autogen.sh autoconf’,

        autoconf-related tools should be run here.

2017-08-02  Toon Claes  <toon@iotcl.com>

2017-08-02  Paul Eggert  <eggert@cs.ucla.edu>

        When renaming a file, ask only if EEXIST or ENOSYS

        * src/fileio.c (Frename_file): Avoid calling Ffile_directory_p
        more than once on FILE.  Use renameat_noreplace, so that we can
        ask the user (and unlink and retry) only if this fails with errno
        == EEXIST or ENOSYS.  This avoids the need to ask the user for
        permission to do an operation that will fail anyway.  Simplify
        computation of ok_if_already_exists for subsidiary functions.
        * src/filelock.c (rename_lock_file): Prefer renameat_noreplace
        if it works, as this avoids the need to link and unlink.
        * src/lisp.h (renameat_noreplace): New decl.
        * src/sysdep.c [HAVE_LINUX_FS_H]: Include linux/fs.h and sys/syscall.h.
        (renameat_noreplace): New function.

2017-08-02  Paul Eggert  <eggert@cs.ucla.edu>

        When creating a link, ask only if EEXIST

        * src/fileio.c (Fadd_name_to_file, Fmake_symbolic_link):
        Ask the user (and unlink and retry) only if link creation fails
        with errno == EEXIST.  This avoids the need to ask the user for
        permission to do an operation that will fail anyway.

        Don’t worry about unlink if errno == ENOENT

        * src/fileio.c (Fdelete_file):
        * src/keyboard.c (Fopen_dribble_file): Do not report failure to
        remove a file if unlink fails with errno == ENOENT.  This can
        happen even if Emacs is the only program removing the file, in
        case an NFS cache overflows.  The file does not exist if errno ==
        ENOENT, so it is OK to proceed.

        Preserve point under 'dired-auto-revert-buffer' (third case)

        * lisp/files.el (find-file): Use pop-to-buffer-same-window

        The first two replace a previous test that combined them; that
        test intermittently fails in the Hydra build system, so maybe
        separating the two cases will help locate the point of
        failure.  The third test involves find-file but is here
        because it, like the others, is testing the effect of
        dired-auto-revert-buffer.

        Fix C++ class initializers not always being fontified at mode start.

        The problem here happened when an "outer list" of declarations moved beyond an

        Although I don't see how this bug can occur with vanilla GnuTLS 3.2.1,
        perhaps hydra was using a modified GnuTLS.
        * src/gnutls.c (Fgnutls_ciphers): Don't assume GNUTLS_CIPHER_NULL
        is at the end of the list returned by gnutls_cipher_list,

        GnuTLS integer-overflow and style fixes

        This tweaks the recently-added GnuTLS improvements so that
        they avoid some integer-overflow problems and follow typical
        Emacs style a bit better.
        * configure.ac (HAVE_GNUTLS3_HMAC, HAVE_GNUTLS3_AEAD)
        (HAVE_GNUTLS3_CIPHER): Use AC_CACHE_CHECK so that the
        configure-time results are displayed.
        * src/fns.c (extract_data_from_object): Return char *, not char
        const *, since one gnutls caller wants a non-const pointer.  Use
        CONSP rather than !NILP when testing for conses.  Use CAR_SAFE
        instead of rolling our own code.  Prefer signed types to unsigned
        when either will do.  Report problems for lengths out of range,
        instead of silently mishandling them.
        * src/gnutls.c (emacs_gnutls_strerror): New function, to simplify
        callers.  All callers of gnutls_sterror changed.
        (Fgnutls_boot): Check for integers out of range rather than
        silently truncating them.

        (gnutls_symmetric_aead, gnutls_symmetric):
        Work even if ptrdiff_t is wider than ‘long’.
        (gnutls_symmetric, Fgnutls_hash_mac, Fgnutls_hash_digest):

        wrapper.

        C++ Mode.  Fix anomaly occurring when a ">" is deleted then reinserted.

        This fontification anomaly happened because after deleting the ">",
        c-forward-<>-arglist parses the preceding identifier as a putative type but
        stores it in c-found-types before it becomes clear it is not an unambiguous
        type.  c-forward-<>-arglist fails, leaving the spurious type id in
        c-found-types.  Fix this by "binding" c-found-types "to itself" in
        c-forward-<>-arglist, and restoring the original value when that function call
        fails.

        * lisp/progmodes/cc-engine.el (c-copy-found-types): New function.
        (c-forward-<>-arglist): Record the original value of c-found-types at the

        relocate value for named cells as they keep the same symbol.
        (ses-rename-cell): Set new cell name symbol to cell value --- do not
        rely on recalculating.  Push cells with updated data --- cell name,
        cell reference list, or cell formula --- to deferred write list.

        * test/lisp/ses-tests.el: New file, with 7 tests for SES.

        Fix core dump in substitute-object-in-subtree

        Without this fix, (substitute-object-in-subtree #0=(#0# 'a) 'a)
        would dump core, since the C code would recurse indefinitely through
        the infinite structure.  This patch adds an argument to the function,
        and renames it to lread--substitute-object-in-subtree as the function
        is not general-purpose and should not be relied on by outside code.
        See Bug#23660.
        * src/intervals.c (traverse_intervals_noorder): ARG is now void *,
        not Lisp_Object, so that callers need not cons unnecessarily.
        All callers changed.  Also, remove related #if-0 code that was
        “temporary” in the early 1990s and has not been compilable for
        some time.
        * src/lread.c (struct subst): New type, for substitution closure data.
        (seen_list): Remove this static var, as this info is now part of
        struct subst.  All uses removed.
        (Flread__substitute_object_in_subtree): Rename from
        Fsubstitute_object_in_subtree, and give it a 3rd arg so that it
        doesn’t dump core when called from the top level with an
        already-cyclic structure.  All callers changed.
        (SUBSTITUTE): Remove.  All callers expanded and then simplified.
        (substitute_object_recurse): Take a single argument SUBST rather
        than a pair OBJECT and PLACEHOLDER, so that its address can be
        passed around as part of a closure; this avoids the need for an
        AUTO_CONS call.  All callers changed.  If the COMPLETED component
        is t, treat every subobject as potentially circular.
        (substitute_in_interval): Take a struct subst * rather than a
        Lisp_Object, for the closure data.  All callers changed.
        * test/src/lread-tests.el (lread-lread--substitute-object-in-subtree):
        New test, to check that the core dump does not reoccur.

        Re-add a useful assertion

        * src/emacs-module.c (module_free_global_ref): Re-add assertion that
        the reference count is zero.  This assertion was removed in commit
        8afaa1321f8088bfb877fe4b6676e8517adb0bb7, but it's not included in the
        test performed by XFASTINT before, because the previous reference
        count could have been zero already in the case of a buggy
        implementation.  This assertion might have detected Bug#27587.

        Further improve electric quote support for Markdown (Bug#24709)

        Markdown sets both 'comment-start' and 'comment-use-syntax' to non-nil
        values.  Therefore 'electric-quote-mode' recognized it as a
        programming mode.  Fix this by first checking whether the current
        major mode is derived from 'text-mode'.

        * lisp/electric.el (electric-quote-post-self-insert-function): Treat
        'text-mode' as stronger signal than comment syntax.

        * test/lisp/electric-tests.el (electric-quote-markdown-in-text)
        (electric-quote-markdown-in-code): Adapt unit tests.

        Optimize UCS normalization tests

        Brings the time for `ucs-normalize-part1' from 200s down to 130s.
        * test/lisp/international/ucs-normalize-tests.el
        (ucs-normalize-tests--parse-column): Use character instead of string
        of length 1 for terminator.  Convert return value into string since
        all callers need that form anyway.
        (ucs-normalize-tests--normalization-equal-p): Rename from
        ucs-normalize-tests--normalize.  Use dedicated buffer instead of
        messing with narrowing.  Take string to compare against and insert it
        into buffer so that compare-buffer-substrings can be used instead of
        allocating a new string from buffer contents.
        (ucs-normalize-tests--normalization-chareq-p): New macro, specialized
        for comparing single character.
        (ucs-normalize-tests--rule1-holds-p)
        (ucs-normalize-tests--rule2-holds-p): Turn into defsubst.

        Semi-automate the procedure for updating UCS normalize test bad lines

        * test/lisp/international/ucs-normalize-tests.el: Remove incorrect
        commentary describing a manual procedure for producing the updated
        failing lines, it did not actually work.  Replace it with pointer to
        new function which prints the updated values.
        (ucs-normalize-tests--rule1-holds-p): Renamed from
        ucs-normalize-tests--invariants-hold-p.

        (ucs-normalize-check-failing-lines): New functions, used to update
        the *--failing-lines-part* variables.

        Module assertions: check for garbage collections

        It's technically possible to write a user pointer finalizer that calls
        into Emacs module functions.  This would be disastrous because it
        would allow arbitrary Lisp code to run during garbage collection.
        Therefore extend the module assertions to check for this case.

        * src/emacs-module.c (module_assert_thread): Also check whether a
        garbage collection is in progress.

        * test/data/emacs-module/mod-test.c (invalid_finalizer)
        (Fmod_test_invalid_finalizer): New test module functions.
        (emacs_module_init): Register new test function.

        * test/src/emacs-module-tests.el (module--test-assertion)
        (module--with-temp-directory): New helper macros.

        lnum_bytepos, lnum_width, and lnum_pixel_width.
        * src/indent.c (line_number_display_width): New function,
        refactored from line-number width calculations in vertical-motion.
        (Fvertical_motion): Call line_number_display_width when the width
        of line-number display is needed.
        (Fline_number_display_width): New defun.
        (syms_of_indent): Defsubr it.
        * src/indent.c (Fvertical_motion): Help C-n/C-p estimate correctly
        the width used up by line numbers by looking near the window-start
        point.  If window-start is outside of the accessible portion,
        temporarily widen the buffer.
        * src/term.c (produce_glyphs): Adjust tab stops for the horizontal
        space taken by the line-number display.

        (should_produce_line_number, row_text_area_empty): New functions.
        (try_window_reusing_current_matrix): Don't use this method when
        display-line-numbers is in effect.
        (try_window_id, try_cursor_movement): Disable these optimizations
        when the line-number-current-line face is different from
        line-number face and for relative line numbers.
        (try_window_id, redisplay_window, try_cursor_movement): For
        visual line-number display, disable the same redisplay
        optimizations as for relative.

        space taken by the line-number display.
        (hscroll_window_tree): Adjust hscroll calculations to line-number
        display.
        (DISP_INFINITY): Renamed from INFINITY to avoid clashes with
        math.h; all users changed.
        (set_cursor_from_row): Fix calculation of cursor X coordinate in
        R2L rows with display-produced glyphs at the beginning.
        (display_line): Use should_produce_line_number to determine
        whether a line number should be produced for each glyph row, and
        maybe_produce_line_number to produce line numbers.
        Don't display line numbers in the minibuffer and in tooltip

        Electric quotes: Improve support for Markdown mode (Bug#24709)

        Introduce a new user option 'electric-quote-context-sensitive'.  If
        non-nil, have ' insert an opening quote if sensible.

        Also introduce a new variable 'electric-quote-code-faces'.  Major
        modes such as 'markdown-mode' can add faces to this list to treat text
        as inline code and disable electric quoting.

        Remove FIXME comments about sentinel values

        These FIXMEs can't be addressed because they would require breaking
        changes to the module API.  Furthermore, other module functions don't
        return sentinel values as well, so users generally have to call
        non_local_exit_check anyway.

        Make C++ digit separators work.  Amend the handling of single quotes generally

        Single quotes, even in strings and comments, are now marked with the
        "punctuation" syntax-table property, except where they are validly bounding a

        Improve ert backtrace recording

        Change ert to use the new `backtrace-frames' function instead of
        collecting frames one by one with `backtrace-frame'.  Additionally,
        collect frames starting from `signal' instead the somewhat arbitrary
        "6 from the bottom".  Skipping 6 frames would skip the expression that
        actually caused the signal that triggered the debugger.  Possibly 6
        was chosen because in the case of a failed test, the triggering frame
        is an `ert-fail' call, which is not so interesting.  But in case of a
        test throwing an error, this drops the `error' call which is too much.

        * lisp/emacs-lisp/debug.el (debugger-make-xrefs): Remove.

        Port recent frame changes to GCC 7

        * src/frame.c (keep_ratio): New arg P.  Caller changed.  Since it

        * src/xterm.c (x_free_frame_resources): Remove new cursors for
        dragging frame borders.
        * src/xterm.h (struct x_output): Add new cursor types for
        dragging frame borders.

        * doc/lispref/display.texi (Size of Displayed Text): Document

        'bottom-visible' parameters.
        (Management Parameters): Mention that `override-redirect' has
        no effect on MS Windows.
        (Font and Color Parameters): Mention child frames for `alpha'
        parameter.
        (Child Frames): Rewrite section with description and cross

        Problem reported by Mike Kupfer in:
        https://lists.gnu.org/r/emacs-devel/2017-06/msg00512.html
        * lisp/emacs-lisp/lisp-mnt.el (lm-crack-copyright):

        indentation than earlier lines.

2017-06-24  Eli Zaretskii  <eliz@gnu.org>

        Minor change in NEWS.

        Improve documentation in NEWS.

2017-06-24  Eli Zaretskii  <eliz@gnu.org>

        Move additional hscrolling code into a suitable 'if'

        * src/xdisp.c (hscroll_window_tree): Make additional calculations
        regarding glyphs produced for line numbers conditional on
        line-number display.

2017-06-24  Eli Zaretskii  <eliz@gnu.org>

        Partial fix of hscroll of truncated lines with line numbers

        * src/xdisp.c (x_produce_glyphs, hscroll_window_tree): Adjust
        hscroll calculations to line-number display.
        * src/term.c (produce_glyphs): Adjust tab stop to window's
        hscroll.  These two changes fix horizontal scrolling when line
        numbers are displayed.  But there's still a bug: the horizontal
        shift of lines that begin with a TAB is different from the rest.
        * src/xdisp.c (move_it_in_display_line_to): Call
        should_produce_line_number to determine whether a line number
        should be produced for this screen line.

2017-06-24  Noam Postavsky  <npostavs@gmail.com>

        Don't change byte-compile-delete-errors at runtime (Bug#27340)

        * lisp/emacs-lisp/eieio-core.el: Confine `cl-declaim' calls to compile
        time.

2017-06-24  Eli Zaretskii  <eliz@gnu.org>

        Allow Lisp program to disable line-number display for specific lines

        * etc/NEWS: Update the documentation.

        * src/xdisp.c (syms_of_xdisp) <display-line-numbers-disable>: New
        symbol.
        (should_produce_line_number): New function.
        (display_line): Use should_produce_line_number to determine
        whether a line number should be produced for each glyph row.

2017-06-24  Stefan Monnier  <monnier@iro.umontreal.ca>

        * lisp/net/html2text.el: Move to obsolete/.

2017-06-24  Eli Zaretskii  <eliz@gnu.org>

        Support a separate face for displaying the current line's number

        * lisp/faces.el (line-number-current-line): New face.

        * src/xdisp.c (syms_of_xdisp) <line-number-current-line>: New
        symbol.
        (try_window_id, try_cursor_movement): Disable these optimizations
        when the line-number-current-line face is different from
        line-number face.
        (maybe_produce_line_number): Display the current line in the
        line-number-current-line face, if it's different from line-number.

2017-06-24  Eli Zaretskii  <eliz@gnu.org>

        Change display of current line in relative mode

        * src/xdisp.c (maybe_produce_line_number): In relative mode
        display the current line number as its absolute value, not as zero.

2017-06-24  Eli Zaretskii  <eliz@gnu.org>

        Rename display-line-width

        * etc/NEWS:
        * src/xdisp.c (syms_of_xdisp, maybe_produce_line_number):
        * lisp/cus-start.el: Rename display-line-width to
        display-line-number-width.

2017-06-24  Eli Zaretskii  <eliz@gnu.org>

        Fix tab stops when line numbers are displayed

        * src/xdisp.c (x_produce_glyphs):
        * src/term.c (produce_glyphs): Adjust tab stops for the horizontal
        space taken by the line-number display.

2017-06-24  Eli Zaretskii  <eliz@gnu.org>

        Fix crashes on TTY frames due to negative lnum_width.

        Don't display line numbers in the minibuffer and in tooltip frames.

2017-06-24  Eli Zaretskii  <eliz@gnu.org>

        Fix problems with line-number updates in Follow mode

        * src/xdisp.c (redisplay_window): If forced window-start requires
        to move a window's point, and the window is under relative
        line-number display, force another round of redisplay to update
        the relative line numbers.  This fixes follow-mode "redisplay" of
        its window group.

        * lisp/frame.el: Add display-line-numbers to the list of variables
        that should trigger redisplay of the current buffer.

2017-06-24  Eli Zaretskii  <eliz@gnu.org>

        Fix display of line numbers with fonts larger than the default

        * src/xdisp.c (maybe_produce_line_number): Update the metrics in
        IT, not in IT->glyph_row, since the latter gets overwritten in
        display_line.  Fixes display of line numbers when the font used
        for them is larger than that of the default face.

2017-06-23  Eli Zaretskii  <eliz@gnu.org>

        Fix background color beyond EOB and cursor display

        * src/xdisp.c:  (maybe_produce_line_number): Use the default face
        for background of the blank glyphs in the line-number area which
        are drawn beyond EOB.
        (display_line): Reset the glyph row's displays_text_p flag only on
        empty lines that don't display line numbers.  This fixes cursor
        display beyond EOB.  Fix the bidi information in the glyphs
        produced for line numbers.  Set the avoid_cursor_p flag of glyphs
        produced for line numbers.

2017-06-23  Eli Zaretskii  <eliz@gnu.org>

        Fix display of indicate-empty-lines when line numbers are displayed

        * src/xdisp.c (row_text_area_empty): New function.
        (display_line): Call row_text_area_empty to verify that a glyph
        row's text area is devoid of any glyphs that came from a buffer or
        a string.  This fixes a bug with empty-lines indication
        disappearing when line numbers or line-prefix are displayed.
        (display_line): Delete the argument FORCE; all callers changed.
        Remove the condition for actually producing the glyphs for the
        line number, as even if the number didn't change we need to
        produce empty space.

2017-06-23  Vincent Belaïche  <vincentb1@users.sourceforge.net>

        Fix symbol relocation when the relocated cell is renamed.

        * lisp/ses.el (ses-sym-rowcol):  Check that the renamed cell
        hashmap has been instantiated before getting data from it.  When
        editing several spreadsheets, and you have spreadsheet #1 with a
        cell named `foo', and no renamed cell in spreadsheet #2, then if
        you make a formula with `foo' in spreadsheet #2, not doing this
        check will make an error.
        (ses-cell-set-formula): Robustify versus incorrect cell references
        given in the user provided formula.  An explicit error message is
        provided after the action when the user gives an incorrect cell
        reference, but the formula edition is not changed.  This means that
        if the incorrect reference is to a cell that is created someday,
        then this new cell will not have the edited cell in its reference
        list.  Fixing this can still be done by editing again the first
        cell formula.
        (ses-relocate-symbol): Do not create symbol of referred-to cell
        when this is a renamed cell.

2017-06-22  Paul Eggert  <eggert@cs.ucla.edu>

        Remove getc_unlocked configure-time check

        * configure.ac (getc_unlocked): Remove check, as unlocked-io now
        does this for us.

2017-06-22  Paul Eggert  <eggert@cs.ucla.edu>

        Use unlocked stdio more systematically

        This can improve performance significantly on stdio-bottlenecked code.
        E.g., make-docfile is 3x faster on my Fedora 25 x86-64 desktop.
        * admin/merge-gnulib (GNULIB_MODULES): Add unlocked-io.
        * lib-src/ebrowse.c, lib-src/emacsclient.c, lib-src/etags.c:
        * lib-src/hexl.c, lib-src/make-docfile.c, lib-src/movemail.c:
        * lib-src/profile.c, lib-src/update-game-score.c:
        Include unlocked-io.h instead of stdio.h, since these programs are
        single-threaded.
        * lib/gnulib.mk.in, m4/gnulib-comp.m4: Regenerate.
        * lib/unlocked-io.h, m4/unlocked-io.m4: New files, copied from Gnulib.
        * src/charset.c, src/cm.c, src/emacs.c, src/image.c, src/keyboard.c:
        * src/lread.c, src/term.c:
        Include sysstdio.h, possibly instead of stdio.h, to define
        the unlocked functions if the system does not provide them.
        * src/charset.c, src/lread.c (getc_unlocked):
        Remove, since sysstdio.h now defines it if needed.
        * src/cm.c (cmputc, cmcheckmagic):
        * src/dispnew.c (update_frame, update_frame_with_menu)
        (update_frame_1, Fsend_string_to_terminal, Fding, bitch_at_user):
        * src/emacs.c (main, Fdump_emacs):

        (our_stdio_fill_input_buffer):
        * src/keyboard.c (record_char, kbd_buffer_get_event, handle_interrupt):
        * src/lread.c (readbyte_from_file):

        (tty_write_glyphs_with_face, tty_insert_glyphs)
        (tty_menu_activate):
        * src/xfaces.c (Fx_load_color_file):
        Use unlocked stdio when it should be safe.
        * src/sysstdio.h (clearerr_unlocked, feof_unlocked, ferror_unlocked)
        (fflush_unlocked, fgets_unlocked, fputc_unlocked, fputs_unlocked)
        (fread_unlocked, fwrite_unlocked, getc_unlocked, getchar_unlocked)
        (putc_unlocked, putchar_unloced): Provide substitutes if not declared.

        unidata: don’t check special casing in unidata-check  (bug#26656)

        * admin/unidata/unidata-gen.el (unidata-check): Do not test special
        casing mapping of characters since that mapping is not constructed from
        the unidata.txt file.
        Also, check for integer decoder and cons char earlier so that less
        unnecessary processing is performed.

2017-06-22  Stefan Monnier  <monnier@iro.umontreal.ca>

        * lisp/descr-text.el (describe-char): Avoid string-*-multibyte

        Avoid string-to-multibyte and string-as-unibyte.
        Don't make *Help* unibyte just because the char was in a unibyte buffer.

2017-06-22  Rasmus  <rasmus@gmx.us>

        Add Org schemas.xml contents to Emacs schemas.xml

        Entries from the Org version of schemas.xml have been added to

2017-06-22  Vincent Belaïche  <vincentb1@users.sourceforge.net>

        Do not hard code A1 cell reference, as it may be renamed.

        * lisp/ses.el (ses-recalculate-all): `A1' -> `(ses-cell-symbol 0 0)'

2017-06-22  Martin Rudalics  <rudalics@gmx.at>

        Fix make_hash_table calls in lread.c

        * src/lread.c (readevalloop, read_internal_start): Fix
        make_hash_table calls to make build succeed.

2017-06-22  Ken Raeburn  <raeburn@raeburn.org>

        Merge several Lisp reader speedups.

2017-06-22  Ken Raeburn  <raeburn@raeburn.org>

        Create less garbage to collect while reading symbols.

        * src/lread.c (read1): When interning a symbol, only create a new
        string object for the name if we're going to use it for a new symbol
        object.

2017-06-22  Ken Raeburn  <raeburn@raeburn.org>

        Replace read_objects assoc list with two hash tables.

        For larger input files with lots of shared data structures, an
        association list is too slow.

        * src/lread.c (read_objects_map, read_objects_completed): New
        variables, replacing read_objects.
        (readevalloop): Initialize them with hash tables before starting a
        top-level read, if they're not already empty hash tables, and reset
        them to Qnil afterwards if something was added to the hash tables.
        (read_internal_start): Likewise.
        (read1): Store first the placeholder and later the newly read object
        into read_objects_map under the specified object number.  If the new
        object can contain a reference to itself, store it in
        read_objects_completed.
        (substitute_objects_recurse): Check read_objects_completed instead of
        read_objects for the known possibly-recursive objects.
        (syms_of_lread): Update initializations.

2017-06-22  Ken Raeburn  <raeburn@raeburn.org>

        Use getc_unlocked.

        * configure.ac: Check for getc_unlocked.
        * src/charset.c (read_hex, load_charset_map_from_file): Use
        getc_unlocked instead of getc.
        (getc_unlocked) [!HAVE_GETC_UNLOCKED]: Fall back to getc.
        * src/lread.c (readbyte_from_file, Fget_file_char, read1,
        getc_unlocked): Likewise.

2017-06-22  Stefan Monnier  <monnier@iro.umontreal.ca>

        Reduce lread substitutions.

        * src/lread.c (read1): After reading an object using the "#n=" syntax,
        if the read object is a cons cell, instead of recursively substituting
        the placeholder with the new object, mutate the placeholder cons cell
        itself to have the correct car and cdr values.

2017-06-22  Ken Raeburn  <raeburn@raeburn.org>

        Short-circuit substitutions for some simple types.

        Values that don't contain other values cannot be circular, so checking
        for circular objects is a waste of cycles.

        * src/lread.c (substitute_object_recurse): If the subtree being
        examined is a symbol, number, or property-less string, just return
        it.

2017-06-22  Paul Eggert  <eggert@cs.ucla.edu>

        Limit style_format to MAX_ALLOCA

        * src/editfns.c (styled_format): Subtract initial buffer size
        from sa_avail, since it is nontrivial.

2017-06-22  Paul Eggert  <eggert@cs.ucla.edu>

        Limit bidi_find_bracket_pairs to MAX_ALLOCA

        * src/bidi.c (MAX_BPA_STACK): Now a constant, not a macro.
        Shrink it to allow for the two struct bidi_it objects in
        the same frame.
        (PUSH_BPA_STACK): Avoid integer overflow with enormous bidi cache.
        (bidi_find_bracket_pairs): Use compile-time check instead of runtime.

2017-06-22  Paul Eggert  <eggert@cs.ucla.edu>

        Limit insert-file-contents to MAX_ALLOCA

        * src/fileio.c (READ_BUF_SIZE): Don’t allocate more than
        MAX_ALLOCA bytes in a single stack array.

2017-06-21  Paul Eggert  <eggert@cs.ucla.edu>

        Remove malloc_find_address relic

        * src/gmalloc.c (register_heapinfo, _malloc_internal_nolock):
        Omit unnecessary initialization.

2017-06-21  Paul Eggert  <eggert@cs.ucla.edu>

        Fix temacs hybrid_malloc core dump

        Without this patch, ./temacs would dump core sometimes on Fedora
        25 x86-64.  The problem was that the hybrid allocator assumed that
        all pointers into bss_sbrk_buffer are allocated via gmalloc.  This
        assumption is not true on Fedora, because the standard memory
        allocator calls gdefault_morecore, which means its blocks are
        interleaved with our blocks.  Usually the code happened to work,
        because our data structures agreed with the glibc data structures,
        but this was merely luck due to a shared pedigree, and as glibc
        mutates our luck has run out.
        * src/gmalloc.c (ALLOCATED_BEFORE_DUMPING) [HYBRID_MALLOC]:
        Remove; no longer needed.
        (BLOCK): Use unsigned division, as that does the right thing near zero.
        (register_heapinfo, __malloc_internal_nolock, __free_internal_nolock)
        (_realloc_internal_nolock):
        Big blocks now have type -1, not 0, as 0 now means the block is
        not ours.
        (morecore_nolock): Omit now-unnecessary casts to size_t.
        (allocated_via_gmalloc) [HYBRID_MALLOC]: New function.
        (hybrid_free, hybrid_realloc) [HYBRID_MALLOC]: Use it, to
        avoid calling the wrong free or realloc function in some cases.

        (article-transform-date):
        Refactor; add header name if it is missing in user-defined date line.
        (article-date-user): Fix name of date type.

        emacs-module.h: Create emacs_env_26

        This was part of the original design of the module
        API (https://lists.gnu.org/r/emacs-devel/2015-02/msg00960.html),
        but I didn't take it into account when adding the should_quit
        function.

        preprocessor, use configure to build emacs-module.h.

        * lib/strftime.c: Copy from gnulib, reverting Clang-specific
        change which I hope is no longer needed.
        * src/emacs.c (main): Revert rlim_t change, as rlim_t is signed on

        No need to complicate make-docfile.c for Clang

        Don’t worry about __STDC_VERSION__ in emacs-module

        * src/emacs-module.h: Remove __STDC_VERSION__ check.  In the past
        we’ve found that some compilers do not define this symbol even
        when they work well enough.  If necessary features like stdbool.h
        are missing the compiler will complain eventually anyway.

        Remove some tautological comparisons involving rlim_t

        Clang on macOS warns about these with -Wtautological-compare.  POSIX

        unsigned (cf.
        http://pubs.opengroup.org/onlinepubs/009695399/basedefs/sys/resource.h.html),
        so these resource limits can never be negative.

        * src/emacs.c (main): Remove tautological comparisons.

        Use --module-assertions if modules are available

        Implement module assertions for users

        Add a new command-line option '-module-assertions' that users can
        enable developing or debugging a module.  If this option is present,
        Emacs performs additional checks to verify that modules fulfill their
        requirements.  These checks are expensive and crash Emacs if modules
        are invalid, so disable them by default.

        This is a command-line option instead of an ordinary variable because
        changing it while Emacs is running would cause data structure
        imbalances.

        * src/emacs.c (main): New command line option '-module-assertions'.

        * src/emacs-module.c (module_assert_main_thread)
        (module_assert_runtime, module_assert_env, module_assert_value):
        New functions to assert module requirements.
        (syms_of_module): New uninterned variable 'module-runtimes'.
        (init_module_assertions, in_main_thread, module_abort): New helper
        functions.
        (initialize_environment): Initialize value list.  If assertions are
        enabled, use a heap-allocated environment object.
        (finalize_environment): Add assertion that environment list is never
        empty.
        (finalize_runtime_unwind): Pop module runtime object stack.
        (value_to_lisp): Assert that the value is valid.
        (lisp_to_value): Record new value if assertions are enabled.
        (mark_modules): Mark allocated object list.
        (MODULE_FUNCTION_BEGIN_NO_CATCH)
        (module_non_local_exit_check, module_non_local_exit_clear)
        (module_non_local_exit_get, module_non_local_exit_signal)
        (module_non_local_exit_throw): Assert thread and environment.
        (module_get_environment): Assert thread and runtime.
        (module_make_function, module_funcall, module_intern)
        (module_funcall, module_make_integer, module_make_float)
        (module_make_string, module_make_user_ptr, module_vec_get)
        (funcall_module, Fmodule_load): Adapt callers.
        (module_make_global_ref): If assertions are enabled, use the global
        environment to store global values.
        (module_free_global_ref): Remove value from global value list.

        * test/Makefile.in (EMACSOPT): Enable module assertions when testing
        modules.

        * test/data/emacs-module/mod-test.c (Fmod_test_invalid_store)
        (Fmod_test_invalid_load): New functions to test module assertions.
        (emacs_module_init): Bind the new functions.

        * test/src/emacs-module-tests.el (mod-test-emacs): New constant for
        the Emacs binary file.
        (mod-test-file): New constant for the test module file name.
        (module--test-assertions): New unit test.

2017-06-12  Philipp Stephani  <phst@google.com>

        Explicitly require C11 or C++11 in emacs-module.h

        We already implicitly require them by including stdbool.h.  Just make

        * src/lisp.h (Lisp_Misc_Float): Remove.  This placeholder has been
        unused for two decades; if we ever want to change floats to be a

        Allow non-local exits in module initializers

        Previously signals, throws, and quits from module initialization

        return code, so allow non-local exits.

        * src/emacs-module.c (module_signal_or_throw): New helper function.

        bindings into a single entry in the main environment under
        `:cl-symbol-macros'.
        (cl--sm-macroexpand): Look up symbol bindings in the
        `:cl-symbol-macros' entry of the environment.

        Otherwise, `tramp-test10-write-region' could fail.

2017-06-05  Philipp Stephani  <phst@google.com>

        Inline module_has_cleanup

        This constant is only used once, and we fail compilation anyway if
        it's false.

        * src/emacs-module.c (MODULE_SETJMP_1): Inline __has_attribute.

2017-06-05  Philipp Stephani  <phst@google.com>

        Add missing dependency to test module source file

2017-06-05  Paul Eggert  <eggert@cs.ucla.edu>

        Omit space that broke ‘make check’

        * src/print.c (print_vectorlike): Omit stray space.

2017-06-05  Paul Eggert  <eggert@cs.ucla.edu>

        Remove easserts etc. from emacs-module.c

        Most of these seem to run afoul of the comment "Do NOT use
        'eassert' for checking validity of user code in the module."
        * src/emacs-module.c (MODULE_FUNCTION_BEGIN_NO_CATCH)
        (module_non_local_exit_check, module_non_local_exit_clear)
        (module_non_local_exit_get, module_non_local_exit_signal)
        (module_non_local_exit_throw, module_make_string):
        Remove unnecessary easserts that pointers are nonnull.
        Hardware checks this for us nowadays, and the checks
        just clutter up the code.
        (module_extract_integer): Remove unnecessary verify that
        a C signed integer is in the range INTMAX_MIN..INTMAX_MAX.
        The C standard guarantees this.
        (module_copy_string_contents): Remove unnecessary eassert
        that Lisp strings are null-terminated.
        (module_function_arity): Remove unnecessary easserts that
        function arities are in range.

2017-06-05  Paul Eggert  <eggert@cs.ucla.edu>

        Remove unnecessary checking in emacs-module.c

        * src/emacs-module.c (module_copy_string_contents):
        Remove checking, as string lengths are always nonnegative and less
        than STRING_BYTES_BOUND, and this is checked elsewhere.
        (module_make_string): Check length against STRING_BYTES_BOUND, a
        tighter bound than MOST_POSITIVE_FIXNUM.  (funcall_module): Don't
        assume that an out-of-range integer is nonnegative.

2017-06-05  Paul Eggert  <eggert@cs.ucla.edu>

        SCHARS and STRING_BYTES are nonnegative

        Tell the compiler that SCHARS and STRING_BYTES are nonnegative, in
        the hopes that this will optimize a bit better.  Also, check this
        at runtime if ENABLE_CHECKING.
        * src/lisp.h (SCHARS, STRING_BYTES):
        eassume that these functions return nonnegative values.
        (STRING_SET_CHARS) [ENABLE_CHECKING]:
        eassert that newsize is nonnegative.

2017-06-05  Noam Postavsky  <npostavs@gmail.com>

        * lisp/desktop.el (desktop-clear): Skip the daemon's frame (Bug#26912).

2017-06-04  Philipp Stephani  <phst@google.com>

        Remove an unused error symbol

        * src/emacs-module.c (syms_of_module): Remove unused error symbol
        'invalid-module-call'.

2017-06-04  Philipp Stephani  <phst@google.com>

        Support quitting in modules

        The idea is that modules should call env->should_quit from time to
        time and return as quickly as possible if it returns true.

        * src/emacs-module.c (module_should_quit): New module function.
        (initialize_environment): Use it.
        (funcall_module): Process potential pending quit.

        * src/eval.c (maybe_quit): Add reference to module_should_quit.

2017-06-04  Philipp Stephani  <phst@google.com>

        Use more specific errors for module load failure

        * src/emacs-module.c (syms_of_module): Add more specific error
        symbols.
        (Fmodule_load): Use them.

2017-06-04  Philipp Stephani  <phst@google.com>

        Remove an unneeded assertion

        * src/emacs-module.c (module_copy_string_contents): Remove unneeded
        assertion.  If this assertion triggers, we raise an error anyway.

2017-06-04  Philipp Stephani  <phst@google.com>

        Guard against signed integer overflows

        * src/emacs-module.c (module_extract_integer)
        (module_copy_string_contents, module_make_string): Guard against
        signed integer overflows.

2017-06-04  Philipp Stephani  <phst@google.com>

        Add a couple more assertions to the module code

        These can help module authors debug crashes.

        * src/emacs-module.c (module_non_local_exit_check)
        (module_non_local_exit_clear, module_non_local_exit_get)
        (module_non_local_exit_signal, module_non_local_exit_throw)
        (module_copy_string_contents, module_make_string)
        (funcall_module, initialize_environment): Add assertions

2017-06-04  Philipp Stephani  <phst@google.com>

        Use ATTRIBUTE_MAY_ALIAS where alias violations are likely

        In particular, alias violations are likely for the return values of
        dlsym(3), which get cast around arbitrarily.

        * src/emacs-module.c (Fmodule_load): Use ATTRIBUTE_MAY_ALIAS.

2017-06-04  Philipp Stephani  <phst@google.com>

        Simplify interface of dynlib_attr.

        Instead of returning bool, set the argument pointers to NULL if the
        information is not available.

        * src/dynlib.c (dynlib_addr): Don't return bool.

2017-06-04  Philipp Stephani  <phst@google.com>

        Rationalize environment lifetime management functions

        * src/emacs-module.c (Fmodule_load, funcall_module): Adapt callers.
        (finalize_environment): Add parameter for public part of the
        environment, like 'initialize_environment'.  Add assertions.

2017-06-04  Philipp Stephani  <phst@google.com>

        Rework printing of module functions

        Fix a FIXME in emacs-module.c.  Put the printing into print.c, like
        other types.

        * src/print.c (print_vectorlike): Add code to print module functions.

        * src/emacs-module.c (funcall_module): Stop calling
        'module_format_fun_env'.  Now that module functions are first-class
        objects, they can be added to signal data directly.
        (module_handle_signal): Remove now-unused function
        'module_format_fun_env'.

        * test/src/emacs-module-tests.el (mod-test-sum-test): Adapt unit test.

        * src/eval.c (funcall_lambda): Adapt call to changed signature of
        'funcall_module'.

2017-06-04  Philipp Stephani  <phst@google.com>

        Define helper macro to reduce code duplication

        * src/emacs-module.c (MODULE_FUNCTION_BEGIN_NO_CATCH): New helper
        macro.
        (MODULE_FUNCTION_BEGIN, module_type_of, module_is_not_nil, module_eq):
        Use it.

2017-06-04  Philipp Stephani  <phst@google.com>

        Remove two FIXMEs that can't be fixed

2017-06-04  Eli Zaretskii  <eliz@gnu.org>

        Avoid slow startup in daemon mode when global-linum-mode is on

        * lisp/linum.el (linum-on): Don't turn on linum-mode in a
        non-client frame of a daemon session.  (Bug#27210)

2017-06-04  Paul Eggert  <eggert@cs.ucla.edu>

        Fix eldoc bug with curved quote

        * lisp/progmodes/elisp-mode.el (elisp-get-fnsym-args-string):
        Substitute quotes in documentation before returning it (Bug#27159).

2017-06-04  Paul Eggert  <eggert@cs.ucla.edu>

        Tune ‘format’ after recent fix

        * doc/lispref/strings.texi (Formatting Strings):
        * src/editfns.c (Fformat): Format field numbers no longer need
        to be unique, reverting the previous doc change since that has
        now been fixed.  Also, document that %% should not have modifiers.
        * src/editfns.c (styled_format): Improve performance.  Remove
        the need for the new prepass over the format string, by using
        a typically-more-generous bound for the info array size.
        Initialize the info array lazily.  Move string inspection to
        the same area to help caching.  Avoid the need for a
        converted_to_string bitfield by using EQ.  Cache arg in a
        local and avoid some potential aliasing issues to help the
        compiler.  Info array is now 0-origin, not 1-origin.

2017-06-04  Nikolay Kudryavtsev  <nikolay.kudryavtsev@gmail.com>

        Improve of file-local-name use in vc-git-checkin

        * lisp/vc/vc-git.el (vc-git-checkin): Use file-local-name only
        when calling git commit.

2017-06-03  Simen Heggestøyl  <simenheg@gmail.com>

        Support a new CSS indentation style

        * lisp/textmodes/css-mode.el (css-smie-rules): Indent after property
        immediately followed by a newline.

        * test/manual/indent/css-mode.css: Add test for the change above.

        * test/manual/indent/scss-mode.scss: Ditto.

2017-06-03  Philipp Stephani  <phst@google.com>

        Fix a bug when using format field numbers

        Previously styled_format overwrite the argument vector.  This is no
        longer possible because there might be more than one specification per
        argument.  Use the existing auxiliary info array instead.

        * src/editfns.c (styled_format): Record arguments in the info
        structure instead of overwriting them.
        * test/src/editfns-tests.el (format-with-field): Add unit test.

2017-06-03  Paul Eggert  <eggert@cs.ucla.edu>

        Document uniqueness limitation of ‘format’

        * doc/lispref/strings.texi (Formatting Strings):
        * src/editfns.c (Fformat):
        Document that field numbers should be unique within a format.

2017-06-03  Glenn Morris  <rgm@gnu.org>

        Small rmailmm fix (bug#27203)

        * lisp/mail/rmailmm.el (rmail-mime-insert-bulk):
        Fall back to HOME if no match in rmail-mime-attachment-dirs-alist.

2017-06-03  Glenn Morris  <rgm@gnu.org>

        * admin/authors.el (authors-aliases): Addition.

2017-06-03  Glenn Morris  <rgm@gnu.org>

        Add watch for password back to inferior python comint filter

        It was removed along with other items for speed (bug#16875),
        but doesn't seem to have been causing an issue, and it's useful to
        have it there (bug#27154).
        * lisp/progmodes/python.el (inferior-python-mode):
        Add comint-watch-for-password-prompt to comint-output-filter-functions.

2017-06-03  Ryan  <rct@thompsonclan.org>  (tiny change)

        Use completing-read-default in tmm-prompt

        tmm uses completing-read, but customizes its behavior so much
        that any alternative completing-read-function will almost
        certainly break it.  For example, both ido-ubiquitous and ivy have
        special code to deactivate themselves for tmm.
        * lisp/tmm.el (tmm-prompt): Use completing-read-default instead of
        completing-read.  (Bug#27193)

2017-06-02  Mats Lidell  <mats.lidell@cag.se>

        * etc/tutorials/TUTORIAL.sv: synced with TUTORIAL (Bug#20371)

2017-06-02  Glenn Morris  <rgm@gnu.org>

        Fix with-todo-test

        * test/lisp/calendar/todo-mode-tests.el (with-todo-test):
        HOME should be a directory, not a file.  Delete it when finished.

2017-06-02  Lele Gaifax  <lele@metapensiero.it>  (tiny change)

        Update TUTORIAL.it

        * etc/tutorials/TUTORIAL.it: Adjust to recent changes in TUTORIAL.

        Fix cursor position in Dired buffers after dired-sort-toggle

        * src/xdisp.c (display_and_set_cursor): Record cursor coordinates
        even if the frame is marked as garbaged.  (Bug#27187)

2017-06-02  Eli Zaretskii  <eliz@gnu.org>

        Update TUTORIAL.he

        * etc/tutorials/TUTORIAL.he: Adjust to recent changes in TUTORIAL.

2017-06-02  Noam Postavsky  <npostavs@gmail.com>

        * etc/tutorials/TUTORIAL: Explain how to stop the tutorial (Bug#20371).

2017-06-02  Paul Eggert  <eggert@cs.ucla.edu>

        Limit format fields to more POSIX-like spec

        * doc/lispref/strings.texi (Formatting Strings):
        Don’t allow mixing numbered with unnumbered format specs.
        * src/editfns.c (styled_format): Don’t bother checking for field 0,
        since it doesn’t crash and the behavior is not specified.
        * test/src/editfns-tests.el (format-with-field): Adjust tests to
        match current doc.  Add more tests for out-of-range fields.

2017-06-02  Paul Eggert  <eggert@cs.ucla.edu>

        Improve performance by avoiding strtoumax

        This made (string-to-number "10") 20% faster on my old desktop,
        an AMD Phenom II X4 910e running Fedora 25 x86-64.
        * admin/merge-gnulib (GNULIB_MODULES): Remove strtoumax.
        * lib/gnulib.mk.in, m4/gnulib-comp.m4: Regenerate.
        * lib/strtoul.c, lib/strtoull.c, lib/strtoumax.c, m4/strtoull.m4:
        * m4/strtoumax.m4: Remove.
        * src/editfns.c (str2num): New function.
        (styled_format): Use it instead of strtoumax.  Use ptrdiff_t
        instead of uintmax_t.  Check for integer overflow.
        * src/lread.c (LEAD_INT, DOT_CHAR, TRAIL_INT, E_EXP):
        Move to private scope and make them enums.
        (string_to_number): Compute integer value directly during
        first pass instead of revisiting it with strtoumax later.

2017-06-02  Paul Eggert  <eggert@cs.ucla.edu>

        Minor improvements to format field numbers

        * src/editfns.c (styled_format): Allow field numbers in a %% spec.
        No need for a special diagnostic for field numbers greater than
        PTRDIFF_MAX.  Reword diagnostic for field 0.
        * test/src/editfns-tests.el (format-with-field): Adjust to match.

2017-06-02  Philipp Stephani  <phst@google.com>

        Implement field numbers in format strings

        A field number explicitly specifies the argument to be formatted.
        This is especially important for potential localization work, since
        grammars of various languages dictate different word orders.

        * src/editfns.c (Fformat): Update documentation.

        Make sure exiting todo-mode buffer buries it (bug#27121)

        This failed due to commit ea3ae33b from 2013-05-16, which prevented
        quitting todo-mode buffer after visiting todo-archive buffer from
        making the archive buffer current again.  Avoid this now by simply
        killing the archive buffer, since there's no need to keep it a live
        buffer.  Consequently, quitting a todo-mode buffer can now use
        bury-buffer without an argument, which ensures that is will not
        becomes current on quitting the buffer that replaced it in the window.

        * lisp/calendar/todo-mode.el (todo-quit): Kill todo-archive-mode
        buffer instead of burying it.  This now allows exiting the
        todo-mode buffer by bury-buffer without an argument, so do that.

        Depromiscuify inotify with IN_MASK_ADD

        Use IN_MASK_ADD instead of using a no-longer-promiscuous-enough
        mask.  This simplifies the code and restores the ability to
        use IN_ACCESS, IN_CLOSE_WRITE, IN_CLOSE_NOWRITE, and IN_OPEN
        in some cases (Bug#26973).
        * src/inotify.c (INOTIFY_DEFAULT_MASK): Remove.
        (Finotify_add_watch): Use IN_MASK_ADD instead.

        Restore inotify onlydir support

        There was no need to remove it in the 2017-03-26 inotify change,
        as it is like IN_DONT_FOLLOW and does not affect other watchers
        for the same file.
        * src/inotify.c (symbol_to_inotifymask, Finotify_add_watch)
        (syms_of_inotify): Bring back onlydir.

        (Finotify_add_watch): Use aspect_to_inotifymask earlier, to
        simplify the code.

        Don't attempt to recover from undefined behavior in some cases

        These functions can only be run in batch mode and exit Emacs on
        return, so nothing can be recovered.  Disable unsafe recover
        mechanisms so that we get real failures and good stack traces on
        fatal signals.

        Avoid another compiler warning on macOS

        When configured with --without-ns, HAVE_NS is not defined on macOS,
        thus 'memory-limit' calls the deprecated sbrk(2) function.  Avoid that
        by using the pre-defined __APPLE__ preprocessor macro.

        * src/alloc.c (Fmemory_limit): Never use sbrk(2) on macOS.

        Make ff-find-other-file symmetric for C++ (Bug#20192)

        `cc-other-file-alist' has a mapping of file extensions to switch
        between headers and sources, but the mappings weren't completely
        symmetric.  In particular .cpp would map to .hh, but .hh would NOT map
        to .cpp.

        Improve module function terminology

        Module functions were previously called "function environments" when
        the functions created by module_make_functions were lambdas.  Now we
        can adapt the terminology and rename "function environments" to
        "module functions" everywhere.  This also removes the name clash
        between "function environments" and "module environments."

        Reimplement module functions

        Instead of a lambda, create a new type containing all data required to
        call the function, and support it in the evaluator.  Because this type
        now also needs to store the function documentation, it is too big for
        Lisp_Misc; use a pseudovector instead.  That also has the nice benefit
        that we don't have to add special support to the garbage collector.

        Since the new type is user-visible, give it a predicate.

        Now we can easily support 'help-function-args' and 'func-arity'; add
        unit tests for these.

        * src/lisp.h (allocate_module_function, MODULE_FUNCTIONP)
        (XMODULE_FUNCTION): New pseudovector type 'module function'.

        * src/eval.c (FUNCTIONP): Also treat module functions as functions.
        (funcall_lambda, Ffuncall, eval_sub): Add support for calling module
        functions.
        (Ffunc_arity): Add support for detecting the arity of module
        functions.

        * src/emacs-module.c (module_make_function): Adapt to new structure.
        Return module function object directly instead of wrapping it in a
        lambda; remove FIXME.
        (funcall_module): New function to call module functions.  Replaces
        `internal--module-call' and is called directly from eval.c.
        (syms_of_module): Remove internal helper function, which is no longer
        needed.
        (module_function_arity): New helper function.

        * src/data.c (Ftype_of): Adapt to new implementation.
        (Fmodule_function_p, syms_of_data): New user-visible function.  Now
        that module functions are first-class objects, they deserve a
        predicate.  Define it even if not compiled with --enable-modules so
        that Lisp code doesn't have to check for the function's existence.

        * src/doc.c (Fdocumentation): Support module functions.

        * src/print.c (print_object): Adapt to new implementation.

        * src/alloc.c (mark_object): Specialized garbage collector support is
        no longer needed.

        * lisp/help.el (help-function-arglist): Support module functions.
        While there, simplify the arity calculation by using `func-arity',
        which does the right thing for all kinds of functions.

        * test/data/emacs-module/mod-test.c: Amend docstring so we can test
        the argument list.

        * test/src/emacs-module-tests.el (mod-test-sum-docstring): Adapt to
        new docstring.
        (mod-test-non-local-exit-signal-test): Because `internal--module-call'
        is gone, the backtrace has changed and no longer leaks the
        implementation.
        (module--func-arity): New test for `func-arity'.
        (module--help-function-arglist): New test for `help-function-arglist'.

        Fix automatic hscrolling of only the current line

        * src/xdisp.c (display_line): When hscrolling only the current
        line, increment iterator's first_visible_x and last_visible_x
        values to account for the hscroll.  This propagates the hscroll
        effect on the iterator geometry all the way down to the
        subroutines called by display_line, and avoids scrolling bugs
        under large hscroll values.  (Bug#26994)

        Fix lisp-indent-region and indent-sexp (Bug#26619)

        The new lisp-indent-region introduced in 2017-04-22 "Add new
        `lisp-indent-region' that doesn't reparse the code." is broken because
        it doesn't save the calculated indent amounts for already seen sexp
        depths.  Fix this by unifying the indent-sexp and lisp-indent-region
        code.  Furthermore, only preserve position 2 of the running parse
        when the depth doesn't change.

2017-04-25  Glenn Morris  <rgm@gnu.org>

        Generate each unicode lisp file independently

        This is better for parallel builds, eg it eliminates race
        conditions from having one process write multiple files.
        * admin/unidata/Makefile.in (lparen, unifiles): New variables.

        Don't require bytecomp for running ert tests

        "Fix ert-tests when running compiled" 2016-12-06 accidentally
        introduced a dependency on `bytecomp' into `ert'.  As mentioned in
        "Avoid ert test failures" 2017-04-18, the accidental dependency of ert
        on bytecomp was masked by loading other libraries until recently.

        * lisp/emacs-lisp/ert.el (ert--expand-should-1): Only use
        `byte-compile-macro-environment' if it's bound.
        * test/src/eval-tests.el: Add defvar for dynamic variable
        `byte-compile-debug'.

        an optional argument to allow limiting the summary buffer to just the
        thread-related articles.
        (gnus-refer-thread-limit-to-thread): Introduce customizable variable
        to control whether thread-referral adds the thread to the summary
        buffer or limits to just the thread.
        (gnus-summary-refer-thread): Use the new variable.

2017-04-23  Andrew G Cohen  <cohen@andy.bu.edu>

        Correct gnus-newsgroup-limits in gnus when including thread

        * lisp/gnus/gnus-sum.el (gnus-summary-limit-include-thread): Should

        rather than two.

2017-04-23  Andrew G Cohen  <cohen@andy.bu.edu>

        Improve gnus thread matching of similar subjects

        * lisp/gnus/gnus-sum.el (gnus-summary-limit-include-thread):

        find thread articles with similar subjects.

2017-04-22  Noam Postavsky  <npostavs@gmail.com>

        Add new `lisp-indent-region' that doesn't reparse the code.

        Both `lisp-indent-region' and `lisp-indent-line' now use `syntax-ppss'
        to get initial state, so they will no longer indent string literal
        contents.

        * lisp/emacs-lisp/lisp-mode.el (lisp-ppss): New function, like
        `syntax-ppss', but with a more dependable item 2.
        (lisp-indent-region): New function, like `indent-region-line-by-line'
        but additionally keep a running parse state to avoid reparsing the
        code repeatedly.  Use `lisp-ppss' to get initial state.
        (lisp-indent-line): Take optional PARSE-STATE argument, pass it to
        `calculate-lisp-indent', use `lisp-ppss' if not given.
        (lisp-mode-variables): Set `indent-region-function' to
        `lisp-indent-region'.

2017-04-22  Noam Postavsky  <npostavs@gmail.com>

        Remove ignored argument from lisp-indent-line

        * lisp/emacs-lisp/lisp-mode.el (lisp-indent-line): Remove WHOLE-EXP
        argument, the behavior has long since been handled in
        `indent-for-tab-command'.  Also remove redundant `beg' and `shift-amt'
        variables and use `indent-line-to'.

2017-04-22  Noam Postavsky  <npostavs@gmail.com>

        * lisp/emacs-lisp/lisp-mode.el (indent-sexp): Clean up marker.

2017-04-22  Noam Postavsky  <npostavs@gmail.com>

        Don't reparse the sexp in indent-sexp (Bug#25122)

        * lisp/emacs-lisp/lisp-mode.el (calculate-lisp-indent): Let
        PARSE-START be a parse state that can be reused.
        (indent-sexp): Pass the running parse state to calculate-lisp-indent
        instead of the sexp beginning position.  Saving the
        CONTAINING-SEXP-START returned by `calculate-lisp-indent' is no longer
        needed.  Don't bother stopping if we don't descend below init-depth,
        since we now always scan the whole buffer (via syntax-ppss) anyway.
        * test/lisp/emacs-lisp/lisp-mode-tests.el (indent-sexp): Add blank
        line to test case.

2017-04-22  Vibhav Pant  <vibhavp@gmail.com>

        Add cond test cases for singleton clauses.

        * test/lisp/emacs-lisp/bytecomp-tests.el: Add test cond forms where
          the default clause is a single non-nil expression.

2017-04-22  Vibhav Pant  <vibhavp@gmail.com>

        b-c--cond-jump-table-info: Use correct body for singleton clauses

        * lisp/emacs-lisp/bytecomp.el (byte-compile-cond-jump-table-info):
        When a clause's body consists of a single constant expression, use
        that expression as the body to be compiled. This fixes switch bytecode
        evaluating to nil to such clauses.

2017-04-22  Philipp Stephani  <phst@google.com>

        ffap: Don't switch window unless needed

        When using ffap-other-window, don't change the window configuration
        unless a new buffer has actually been created (Bug#25352).

        configuration if no new buffer has been created.
        * test/lisp/ffap-tests.el (ffap-other-window--bug-25352): Add unit

        cfd-top-level properly.
        (c-forward-decl-or-cast-1): On finding FOO::FOO, check it is followed by "("
        before deciding it is a constructor.

        * lisp/progmodes/cc-fonts.el (c-font-lock-complex-decl-prepare): Negate the

        Fix usage of FRAME_Z_GROUP

        Revert 0d112c00ba0ec14bd3014efcd3430b9ddcfe1fc1 (to fix bug#26325)
        and use a different fix for bug#26068.
        (cl--symbol-macro-key): New function.

        Treat non-erroring lisp call as successful eshell command (Bug#26161)

        This lets a compound command like 'cd .. && echo ok' print 'ok',
        similar to how most other shells behave.

        * lisp/eshell/esh-cmd.el (eshell-exit-success-p): Only check if the
        last exit code was zero, rather than first checking whether the last
        command returned nil.
        (eshell-exec-lisp): Set `eshell-last-command-status' to 1 on error.

2017-04-21  Reuben Thomas  <rrt@sc3d.org>

        Fix reading of tab settings in whitespace-mode

        lisp/whitespace.el (whitespace-indent-tabs-mode)
        whitespace-tab-width): Remove these variables. The underlying
        variables `indent-tabs-mode' and `tab-width' are already buffer-local
        when needed, and whitespace-mode never changes them.
        (whitespace-ensure-local-variables): Remove this function, which only
        existed to set the above variables.
        (whitespace-cleanup-region, whitespace-regexp)
        (whitespace-indentation-regexp, whitespace-report-region)
        (whitespace-turn-on, whitespace-color-on): Adjust these functions to
        use `indent-tabs-mode' and `tab-width' directly, and not call
        `whitespace-ensure-local-variables'.

        bytecomp: Don't inline functions that use byte-switch (Bug#26518)

        * lisp/emacs-lisp/bytecomp.el (byte-compile-unfold-bcf): Don't inline
          FORM if the bytecode uses the byte-switch instruction. It is
          impossible to guess the correct stack depth while inlining such
          bytecode, resulting in faulty code.

        Remove some explicit runtime loads of pcase

        Pcase is macros, so these should have used eval-when-compile.
        Anyway, pcase entry points are autoloaded, so the compiler handles it.

        * lisp/emacs-lisp/generator.el, lisp/emacs-lisp/subr-x.el:
        * lisp/progmodes/xref.el: No need to require pcase.

        Treat pcase-defmacro like defmacro.

        Fix bugs in `with-displayed-buffer-window' and `fit-window-to-buffer'

        * lisp/window.el (with-displayed-buffer-window): When a
        'window-height' action alist entry specifies a function, call
        `temp-buffer-window-show' with a '(window-height . t)' dummy
        entry so `window--try-to-split-window' will bind
        `window-combination-limit' to t and that function does not
        resize any other window but the one we split this one off
        (Bug#25055, Bug#25179).
        (fit-window-to-buffer): Call `window-max-delta' with NOUP t so
        we steal space only from windows in the same combination.
        Stealing space from other windows would not allow us to return
        that space later when this window is deleted (Bug#25055,
        Bug#25179).

        ChangeLog was inadvertently dropped during its commit.  The proper
        ChangeLog is included below as part of the present commit.

        * src/gtkutil.c (xg_set_geometry): When x_gtk_use_window_move
        is set avoid calling x_gtk_parse_geometry (Bug#25851).
        (x_wm_set_size_hint): When x_gtk_use_window_move is set, set
        PPosition, USPosition and USSize flags if requested.
        * src/xterm.c (x_set_offset): With GTK when
        x_gtk_use_window_move is set, leave it entirely to
        gtk_window_move to position the window and skip any
        post-adjustments (Bug#25851 and Bug#25943).
        (x_gtk_use_window_move): New variable.

        Fix a loop in C Mode caused by inadequate analysis of comments.

        After M-;, and the insertion of the opening "/*", the CC Mode after-change
        function got confused, since the new comment opener matched the end of a
        subsequent comment, but moving back over that comment did not come back to the
        starting point.  Fix this.

        * lisp/progmodes/cc-engine.el (c-end-of-macro): Add a limit parameter, wherer
        point is left if no end-of-macro is found before it.
        (c-forward-sws): Change the `safe-start' mechanism.  Now `safe-start' is
        non-nil except where we have an unclosed block comment at the end of a macro.
        This enables us to populate the cache more fully, at the cost of some run
        time.

        Write updated loaddefs to a temporary file and rename into place.

        In a parallel build, byte compilation can be running at the same times
        as loaddefs.el is being regenerated.  However, in a CANNOT_DUMP build,
        loaddefs.el is read at startup and must always be in a usable state.

        * lisp/Makefile.in ($(lisp)/loaddefs.el): Write generated output to
        loaddefs.el.new and then rename it to loaddefs.el.

        and prefer C99-style decls within blocks.
        (GREEK_CAPITAL_LETTER_SIGMA): Rename from CAPITAL_SIGMA, so that
        we are merely using the Unicode name, and make it a constant

        Implement special sigma casing rule  (bug#24603)

        In Greek, a sigma character has two lower case forms which depend on
        their position in the word.  Implement logic determining it.

        * src/casefiddle.c (struct casing_context, case_character_impl): Don’t
        assume inword is true when flag is CASE_UP and false when flag is
        CASE_DOWN.  For final sigma detection we need this information tracked
        reliably;.
        (CAPITAL_SIGMA, SMALL_SIGMA, SMALL_FINAL_SIGMA): New macros defining
        Unicode code point of different forms of sigma letter.
        (case_character): Implement support for final sigma casing.
        (do_casify_multibyte_string, do_casify_multibyte_region): Update after
        changes to case_character.

        * test/src/casefiddle-tests.el (casefiddle-tests-casing): Add test
        cases for final sigma.

2017-04-06  Michal Nazarewicz  <mina86@mina86.com>

        Support casing characters which map into multiple code points  (bug#24603)

        Implement unconditional special casing rules defined in Unicode standard.

        Among other things, they deal with cases when a single code point is
        replaced by multiple ones because single character does not exist (e.g.
        ‘fi’ ligature turning into ‘FL’) or is not commonly used (e.g. ß turning
        into SS).

        * admin/unidata/SpecialCasing.txt: New data file pulled from Unicode
        standard distribution.
        * admin/unidata/README: Mention SpecialCasing.txt.

        * admin/unidata/unidata-gen.el (unidata-gen-table-special-casing,
        unidata-gen-table-special-casing--do-load): New functions generating
        ‘special-uppercase’, ‘special-lowercase’ and ‘special-titlecase’
        character Unicode properties built from the SpecialCasing.txt Unicode
        data file.

        * src/casefiddle.c (struct casing_str_buf): New structure for
        representing short strings used to handle one-to-many character
        mappings.

        (case_character_imlp): New function which can handle one-to-many
        character mappings.
        (case_character, case_single_character): Wrappers for the above
        functions.  The former may map one character to multiple (or no)
        code points while the latter does what the former used to do (i.e.
        handles one-to-one mappings only).

        (do_casify_natnum, do_casify_unibyte_string,
        do_casify_unibyte_region): Use case_single_character.
        (do_casify_multibyte_string, do_casify_multibyte_region): Support new
        features of case_character.
        * (do_casify_region): Updated to reflact do_casify_multibyte_string
        changes.

        (casify_word): Handle situation when one character-length of a word
        can change affecting where end of the word is.

        (upcase, capitalize, upcase-initials): Update documentation to mention
        limitations when working on characters.

        * test/src/casefiddle-tests.el (casefiddle-tests-char-properties):
        Add test cases for the newly introduced character properties.
        (casefiddle-tests-casing): Update test cases which are now passing.

        * test/lisp/char-fold-tests.el (char-fold--ascii-upcase,
        char-fold--ascii-downcase): New functions which behave like old ‘upcase’
        and ‘downcase’.
        (char-fold--test-match-exactly): Use the new functions.  This is needed
        because otherwise fi and similar characters are turned into their multi-
        -character representation.

        * doc/lispref/strings.texi: Describe issue with casing characters versus
        strings.
        * doc/lispref/nonascii.texi: Describe the new character properties.

        Split up casify_region function  (bug#24603)

        No functional changes at this time but splitting casify_region into
        a function dealing with multibyte and another dealing with unibyte
        buffers will make future code changes slightly easier.

        * src/casefiddle.c (casify_region): Move most of the code into two
        new functions:
        (do_casify_multibyte_region, do_casify_unibyte_region): new functions.

2017-04-06  Michal Nazarewicz  <mina86@mina86.com>

        Add support for title-casing letters  (bug#24603)

        * src/casefiddle.c (struct casing_context, prepare_casing_context): Add
        titlecase_char_table member.  It’s set to the ‘titlecase’ Unicode
        property table if capitalization has been requested.
        (case_character): Make use of the titlecase_char_table to title-case
        initial characters when capitalising.

        * test/src/casefiddle-tests.el (casefiddle-tests--characters,
        casefiddle-tests-casing): Update test cases which are now passing.

2017-04-06  Michal Nazarewicz  <mina86@mina86.com>

        Introduce case_character function

        Move single-character casing logic into a separate function so that
        it is collected in a single place.  This will make future changes to
        the logic easier.  This commit introduces no functionality changes.

        * src/casefiddle.c (struct casing_context, prepare_casing_context): New
        structure for saving casing context and function to initialize it.
        (case_character): New function which cases character base on provided
        context.
        (do_casify_integer, do_casify_multibyte_string,
        do_casify_unibyte_string, casify_object, casify_region): Convert to
        use casing_context and case_character.

2017-04-06  Michal Nazarewicz  <mina86@mina86.com>

        Split casify_object into multiple functions

        casify_object had three major cases to cover and those were mostly
        independent of each other.  Move those branches to separate function
        so it’s easier to comprehend each individual case.

        While at it, use somewhat more descriptive ch and cased variable names
        rather than c and c1.

        This commit introduces no functional changes.

        * src/casefiddle.c (casify_object): Split into…
        (do_casify_integer, do_casify_multibyte_string,
        do_casify_unibyte_string): …new functions.

        * doc/lispref/elisp.texi: reference it.
        * doc/lispref/records.texi (Records): reference it.  Document
        behavior when type slot is a record.

        In CANNOT_DUMP builds, allow editing of files named "dump".

        * lisp/loadup.el: Perform the "dump" or "bootstrap" actions like
        calling dump-emacs only if dump-emacs is defined; otherwise, don't
        treat those command-line argument specially.

2017-04-06  Ken Raeburn  <raeburn@raeburn.org>

        In CANNOT_DUMP builds, don't prepare for unexec.

        Having a command-line argument of "dump" or "bootstrap" would trigger
        behavior like not installing signal handlers.  In CANNOT_DUMP modes,
        we should get signal handlers installed regardless of whatever funny
        file names we decide to edit.

        src/emacs.c (main) [CANNOT_DUMP]: Don't enable the "dumping"
        alterations to initialization that prepares the process for unexec.

2017-04-06  Ken Raeburn  <raeburn@raeburn.org>

        Allow a CANNOT_DUMP build to use exec-path during bootstrap.

        During a bootstrap, loading rmail.el invokes movemail to determine its
        flavor, but call-process doesn't work if exec-path is nil.

        * lisp/loadup.el: Only clear exec-path if dumping.

2017-04-06  Ken Raeburn  <raeburn@raeburn.org>

        Fix CANNOT_DUMP build on Darwin/macOS.

        * src/conf_post.h (malloc, realloc, free) [DARWIN_OS && emacs &&

        Prefer 'PSEUDOVECTOR_SIZE_MASK' to its definiens.
        (allocate_record): Check arg range here, not in callers, as this
        simplifies the code.  Use allocate_vectorlike instead of
        allocate_vector, to avoid duplicate runtime tests.
        (Fmake_record, record): Don't mention PSEUDOVECTOR_SIZE_BITS in
        the doc string, as it is not visible to the user.

        Make subprocess functions resolve the default directory

        `call-process' doesn't respect file name handlers in
        `default-directory', so `file-name-non-special' has to resolve them
        for `process-file', `start-file-process', and
        `shell-command' (Bug#25949).

        * lisp/files.el (file-name-non-special): Also resolve default

        Throw a `search-failed' derived error in Info search

        The original fix for Bug#6106 switched from signaling `search-failed'
        to `user-error'.  However, this breaks incremental searching over
        multiple nodes because the isearch code doesn't expect a `user-error'.

        * src/search.c (syms_of_search): New error, `user-search-failed',
        with `user-error' and `search-failed' as parents.
        * doc/lispref/errors.texi (Standard Errors): Document it.
        * etc/NEWS: Announce it.
        * lisp/info.el (Info-search): Use it instead of `user-error' so that
        isearch will handle failed searches correctly.

        * test/Makefile.in (LOGFILES, TESTS): Omit leading "./".
        (TESTS): Omit unnecessary patsubst.
        (test_template): Redo dependency heuristic, hopefully

        subsequent calls to string-width don't signal an error (Bug#26317).
        * lisp/ibuffer.el (ibuffer-compile-format): If a column function returns
        nil, treat it like the empty string.

        Fix C++ fontification problems 500 bytes after typing a space, and other bugs

        Also implement the "asymmetric space" rule for fontifying otherwise
        ambiguous
        declarations/expressions.

        * lisp/progmodes/cc-engine.el (c-before-change-check-<>-operators): Don't set
        c-new-BEG or c-new-END when there is no need.
        (c-forward-decl-or-cast-1): Add "CASE 17.5" to implement the "asymmetric
        space" rule.

        * lisp/progmodes/cc-fonts.el (c-get-fontification-context): New function,
        extracted from c-font-lock-declarations.  Add to this function processing to
        make `context' 'decl for lines contained within parens when these are also
        declarations.
        (c-font-lock-declarations): Call the newly extracted function above in place
        of inline code.

        Some inotify cleanup

        This catches some problems with integer overflow and races
        that I noticed in inotify.c after reviewing the changes
        installed to fix Bug#26126.
        * src/fns.c, src/lisp.h (equal_no_quit): Now extern.
        * src/inotify.c (aspect_to_inotifymask):
        Check for cycles and for improper lists.
        (make_lispy_mask, lispy_mask_match_p): Remove.
        All callers changed to use INTEGER_TO_CONS and CONS_TO_INTEGER.
        (inotifyevent_to_event, add_watch):
        Don’t assume watch descriptors and cookies fit in fixnums.
        (add_watch): Use assoc_no_quit, not Fassoc.
        Avoid integer overflow in (very!) long-running processes where
        the Emacs watch ID could overflow.  Avoid some duplicate code.
        (find_descriptor): New function.
        (remove_descriptor): First arg is now the returned value from
        find_descriptor, rather than the descriptor.  This way, the
        value can be removed without calling Fdelete, which might quit.
        Wait until the end (when watch_list is consistent) before signaling
        any errors.
        (remove_watch, inotify_callback):
        Use find_descriptor to avoid the need for Fdelete.
        (inotify_callback): Use simpler tests for ioctl failure.
        Free temporary buffer if signaled, and put it on the stack if small.
        Use ssize_t to index through read results, to avoid a cast.
        (valid_watch_descriptor): New function, with a tighter check.
        (Finotify_rm_watch, Finotify_valid_p): Use it.
        (Finotify_valid_p): Use assoc_no_quit and ass_no_quit instead
        of Fassoc.  Do not assume the first assoc succeeds.
        * test/src/inotify-tests.el (inotify-valid-p-simple):
        Add inotify-valid-p tests, some of which dump core without
        the fixes noted above.

2017-03-30  Michael Albinus  <michael.albinus@gmx.de>

        * lisp/net/tramp-sh.el (tramp-get-remote-locale): Add "C.UTF-8" as candidate.

2017-03-30  Paul Eggert  <eggert@cs.ucla.edu>

        Fix assoc_no_quit so that it does not quit

        The problem was that it called Fequal, which can quit.
        * src/fns.c (enum equal_kind):
        New enum, to be used in place of a boolean.
        (equal_no_quit): New function.
        (Fmemql, Feql): Use it to compare floats, as a minor tuneup.
        (assoc_no_quit): Use it to avoid quitting, the main point here.
        (internal_equal): Generalize bool to enum equal_kind arg, so that
        there are now 3 possibilities instead of 2.  Do not signal an
        error if EQUAL_NO_QUIT.  Put the arg before the depth, since depth
        should be irrelevant if the arg is EQUAL_NO_QUIT.  All callers
        changed.

        Adjust some search failure errors in info.el

        * lisp/info.el (Info-select-node): The search for beginning of node is
        an internal detail, and is not normally expected to fail, so it should
        not be a user error.
        (Info-complete-menu-item): Failing to find a menu indicates the user
        searched for a menu when there isn't one, so change to `use-error'.

2017-03-28  Alan Mackenzie  <acm@muc.de>

        * lisp/progmodes/cc-defs.el (c-version):  Restore c-version to 5.33

        Don't add `search-failed' to ignored errors in info.el (Bug#6106)

        (Info-select-node, Info-search): Replace (signal 'search-failed ...)
        with (user-error "Search failed: "...).

        * Makefile.in (mostlyclean, clean, maybeclean_dirs, distclean)
        (bootstrap-clean, maintainer-clean):
        Clean ‘test’, not ‘test/automated’.  Test for existence of
        subdirectory only for ‘test’, not for directories that should
        always exist.
        * admin/MAINTAINERS, etc/TODO, lisp/emacs-lisp/bytecomp.el:

        Fix docstring of dabbrev-abbrev-char-regexp

        * lisp/dabbrev.el (dabbrev-abbrev-char-regexp): Using a value of nil
        is equivalent to "\\sw\\|\\s_", and has no special behavior.  If the
        previous character doesn't match, we search backwards for one that
        does, not throw an error.  Replace Lisp example with C based one to
        make it clear that "symbol" means a sequence of word and symbol
        constituent characters, not a Lisp symbol (Bug#358).

        Remove special code handling inotify descriptors.  Remove code
        handling multiple clients per descriptor.
        (file-notify--descriptor): Remove unused function.

        Let inotify-add-watch return a unique descriptor on every
        call, like every other back-end does (Bug#26126).  Prevent
        multiple clients from interfering with each other, when
        watching a shared descriptor.
        * src/inotify.c (watch_list): Extend the format by including a
        id and the provided mask.
        (INOTIFY_DEFAULT_MASK): Default mask used for all clients.

        (add_watch, remove_descriptor, remove_watch): New functions
        for managing the watch_list.
        (inotify_callback): Use the new functions.
        (Finotify_add_watch, Finotify_rm_watch): Remove deprecated
        flags from documentation.  Add check for validity of provided
        descriptor.  Use the new functions.  Use the default mask.
        (INOTIFY_DEBUG): Add new debug conditional.
        (inotify-watch-list, inotify-allocated-p): New debug functions.
        (symbol_to_inotifymask, syms_of_inotify): Remove deprecated symbols.

        Protect against an infloop in python-mode

        There appears to be an edge case caused by using `syntax-ppss' in a
        narrowed buffer during JIT lock inside of Python triple-quote strings.
        Unfortunately it is impossible to reproduce without manually
        destroying the syntactic information in the Python buffer, but it has
        been observed in practice.  In that case it can happen that the syntax
        caches get sufficiently out of whack so that there appear to be
        overlapping strings in the buffer.  As Python has no nested strings,
        this situation is impossible and leads to an infloop in
        `python-nav-end-of-statement'.  Protect against this by checking
        whether the search for the end of the current string makes progress.

        * lisp/progmodes/python.el (python-nav-end-of-statement): Protect
        against infloop.

        Improve configure --with-pop etc. diagnostics

        * configure.ac: Improve diagnostics re --with-pop and
        --with-mailutils (Bug#26102).

2017-03-21  Eli Zaretskii  <eliz@gnu.org>

        Revert "Make --without-pop the default."

        This reverts commit 9319de675e395517f9a7b50cae1a3aad9cd0abc2.

        Don’t remove dependency files when configuring

        Problem reported by Tom Tromey in:
        https://lists.gnu.org/r/emacs-devel/2017-03/msg00533.html
        * configure.ac: Don’t remove */*.o and */deps/* when
        --enable-autodepend is in effect.

2017-03-21  Paul Eggert  <eggert@cs.ucla.edu>

        Make --without-pop the default.

        Suggested by Angelo Graziosi in:
        https://lists.gnu.org/r/emacs-devel/2017-03/msg00431.html
        * configure.ac: Change the default from --with-pop to
        --without-pop.  Adjust diagnostics to match.

2017-03-21  Paul Eggert  <eggert@cs.ucla.edu>

        Streamline dependency-file generation

        * configure.ac (AUTODEPEND_PARENTS): New var.
        mkdir the dependency directories here, to simplify ‘make’.
        Remove dependency files just before outputting Makefiles, so that
        they are preserved if ‘configure’ exits early due to some other problem.
        * lib/Makefile.in, lwlib/Makefile.in, oldXMenu/Makefile.in:
        * src/Makefile.in: Adjust deps strategies to be similar, as follows:
        (MKDEPDIR): Remove.  All uses removed.  This cuts down on the
        number of processes spun off by ‘make’.
        (clean mostlyclean): Remove $(DEPDIR) contents, not $(DEPDIR) itself.
        (distclean): Remove $(DEPDIR) itself.
        * lwlib/Makefile.in (all): Move to front, so that depdir includes
        do not alter default action.

2017-03-21  Paul Eggert  <eggert@cs.ucla.edu>

        Port and simplify example sh script

        * doc/misc/org.texi (noweb-ref): Simplify shell script example and

        Narrow scope of modification hook renabling in org-src fontification

        Modification hooks should be enabled while modifying text in the
        org-src temp buffer, but in 2017-01-29 "Call modification hooks in
        org-src fontify buffers" the hooks were enabled also for modifications
        to the original org buffer.  This causes fontification errors when
        combined with certain packages, as reported in
        https://lists.gnu.org/r/emacs-orgmode/2017-03/msg00420.html.

            (sql-oracle--list-oracle-name): New function.
            (sql-oracle-list-all): Use it.

        Fix problem with out-of-date dependencies

        Problem reported by Robert Marshall in:
        https://lists.gnu.org/r/emacs-devel/2017-03/msg00501.html
        Although this problem has been with us for a while, the recent
        change from Automake to GNU Make exposed it again.
        * configure.ac (AUTO_DEPEND): When autodepending, clean out any
        leftover dependency and object files, since the previous sources'
        dependencies may disagree with the current ones.  Reconfiguring
        typically needs to force a rebuild anyway.

        Fixups for GNU Make switchover

        This fixes some minor problems introduced in the recent switch to GNU
        Make, discovered by further testing.  Without some of these changes
        'make -j' would sometimes have race conditions caused by missing
        dependencies.  (Bug#26100)
        * .gitignore: Remove src/stamp-h.in, src/stamp-h1.
        * Makefile.in ($(MAKEFILE_NAME)): Depend on configure, not
        src/config.in, since the former's timestamp now represents
        the latter's.
        ($(srcdir)/configure): Use plain ./autogen.sh, for consistency
        with other autogen.sh invocations.
        ($(srcdir)/src/stamp-h.in):
        Remove rule, as this file is no longer created.
        * Makefile.in (top_distclean):
        * src/Makefile.in (bootstrap-clean):
        No need to remove stamp-h1, as that was an Automake byproduct
        and Automake is no longer in use.
        * lib/Makefile.in, src/Makefile.in:
        (AUTOCONF_INPUTS, $(top_srcdir)/configure): Remove.
        (../config.status, Makefile): Simplify by limiting dependencies
        to files we care about and files in the repository, and by
        using just one file to represent the timestamps on multiple
        targets updated by the same rule.
        * autogen.sh: Do not create or use src/stamp-h.in.
        Instead, have 'find' test the two output files directly.

2017-03-17  Paul Eggert  <eggert@cs.ucla.edu>

        Switch from Automake to GNU Make

        Emacs assumes GNU Make, and GNU Make has much of the functionality of
        Automake built-in.  The Emacs build process uses Automake primarily
        because Emacs uses some Gnulib code and Gnulib formerly required
        Automake.  Now that Gnulib no longer requires Automake, Emacs can
        stop using Automake and this should simplify Emacs maintenance
        in the future (Bug#26100).  Although this patch may look long, most of
        it is generated automatically: the changes to build-aux/config.guess,
        build-aux/config.sub, build-aux/install-sh, and lib/gnulib.mk.in are
        all done by admin/merge-gnulib.
        * .gitignore: Remove build-aux/ar-lib, build-aux/compile,
        build-aux/config.guess, build-aux/config.sub, build-aux/depcomp,
        build-aux/install-sh, build-aux/missing, and lib/Makefile.in,
        as they are no longer built by autogen.sh.
        Add lib/gnulib.mk, as it is now built by 'configure'.
        Remove nt/gnulib.mk, as it is no longer built by 'make'.
        * INSTALL.REPO, README, admin/make-tarball.txt:
        Remove mention of Automake.
        * Makefile.in (AUTOCONF, AUTOMAKE, AUTOHEADER, ACLOCAL, lib)

        Show ancestor buffer in 3way merges

        Add an option ediff-show-ancestor', to control if the ancestor buffer
        must be shown in 3way merges (Bug#25493); set it non-nil by default.
        Add a toggle to change this option interactively; the original
        value of the option is restored on exit.

        Update the window setup so that the ancestor buffer is
        shown in 3way merges when ediff-show-ancestor is non-nil.

        Any operation on ediff windows must take in account the
        ancestor window as well, when this is shown.

        don't cheat it to think that is performing a comparison, that trick is not
        necessary anymore: simply call 'ediff-setup-diff-regions-function'

        Simplify checks for xdg-open and xdg-email

        browse-url's xdg-open detection was too picky on some GNU/Linux
        desktops; see Bug#25778.  Simplify the code by assuming xdg-open works
        if it is executable, as nowadays this is more likely to be correct than
        trying to use heuristics from a few years ago.  Don't test for nohup: it
        is ineffective nowadays, as xdg-open's child uses the default action for
        SIGHUP even if xdg-open's invoker ignores SIGHUP.  While we're at it,
        allow for Wayland here, as "emacs -nw" might be running in a non-X
        Wayland terminal.
        * lisp/mail/emacsbug.el (report-emacs-bug-can-use-xdg-email):
        * lisp/net/browse-url.el (browse-url-can-use-xdg-open):

        executable.  Allow WAYLAND_DISPLAY as an option.

        Stop abbrev-prefix-mark from adding extra newline (Bug#25767)

        Restore XFLOATINT but with restricted args

        Turn instances of extract_float into XFLOAT_DATA when possible,
        and to a resurrected XFLOATINT when the arg is a number.
        The resurrected XFLOATINT is more like XFLOAT and XINT in
        that is valid only if its arg is a number.  This clarifies
        the ways in which floats can be extracted at the C level.
        * src/editfns.c (styled_format):
        * src/floatfns.c (extract_float, Fexpt):
        Use XFLOATINT rather than open-coding it.

2017-03-01  Paul Eggert  <eggert@cs.ucla.edu>

        Fix rounding error in ‘ceiling’ etc.

        Without this fix, (ceiling most-negative-fixnum -1.0) returns
        most-negative-fixnum instead of correctly signaling range-error,
        and similarly for floor, round, and truncate.
        * configure.ac (trunc): Add a check, since Gnulib’s doc says
        ‘trunc’ is missing from MSVC 9.  The Gnulib doc says ‘trunc’ is
        also missing from some other older operating systems like Solaris
        9 which I know we don’t care about any more, so MSVC is the only
        reason to worry about ‘trunc’ here.
        * src/editfns.c (styled_format): Formatting a float with %c is now an
        error.  The old code did not work in general, because FIXNUM_OVERFLOW_P
        had rounding errors.  Besides, the "if (FLOATP (...))" was in there
        only as a result of my misunderstanding old code that I introduced
        2011.  Although %d etc. is sometimes used on floats that represent
        huge UIDs or PIDs etc. that do not fit in fixnums, this cannot
        happen with characters.
        * src/floatfns.c (rounding_driver): Rework to do the right thing
        when the intermediate result equals 2.305843009213694e+18, i.e.,
        is exactly 1 greater than MOST_POSITIVE_FIXNUM on a 64-bit host.
        Simplify so that only one section of code checks for overflow,
        rather than two.
        (double_identity): Remove.  All uses changed to ...
        (emacs_trunc): ... this new function.  Add replacement for
        platforms that lack ‘trunc’.
        * src/lisp.h (FIXNUM_OVERFLOW_P, make_fixnum_or_float):
        Make it clear that the arg cannot be floating point.
        * test/src/editfns-tests.el (format-c-float): New test.
        * test/src/floatfns-tests.el: New file, to test for this bug.

        Speed generation of ldefs-boot-auto

        Previously, generation of ldefs-boot-auto required at least one full
        bootstrap and, in extreme cases, two. Now, from build system, it
        requires the same time as taken to dump Emacs.

        Remove conditional includes from bootstrap

        Previously, bootstrap-emacs includes optional functionality, depending
        on the platform which is not needed for bootstrap function.  As a
        result, bootstrap-emacs contains different functions in different
        circumstances.  If ldefs-boot-auto.el is generated, then loaded
        functions will not be added to ldefs-boot-auto.el, although they may be
        required during some builds.  With this change, bootstrap-emacs should
        always behave the same way and, therefore, require the same autoloads.

        Find macro binding for symbol-bound macros too (Bug#6848)

        There are 2 ways to bind a macro: with global-set-key or
        kmacro-bind-to-key.  The former binds a key to a symbol, while the
        latter binds to a lambda.  In 2010-03-03 "Fix keyboard macro key
        lookup (Bug#5481)", `insert-kbd-macro' was fixed to detect the lambda
        case, but broke the symbol case.

        * lisp/macros.el (insert-kbd-macro): Also check for bindings of
        MACRONAME.

        h->next_weak when the hash table is not weak.
        (copy_hash_table): Put the copy next to the original in the
        weak_hash_tables list, as this should have better locality

        The rehash_size member of struct Lisp_Hash_Table is now a
        float, not a Lisp_Object.
        * src/alloc.c (purecopy_hash_table): Assign members in order.
        * src/fns.c (make_hash_table): Use EMACS_INT for size and
        float for rehash_size, instead of Lisp_Object for both.

        -1, not nil, is now the convention for end of collision list.
        * src/fns.c (maybe_resize_hash_table): Avoid double-initialization
        of the free list.  Reallocate H->next last, in case other
        reallocations exhaust memory.
        * src/lisp.h (struct Lisp_Hash_Table): ‘next_free’ is now
        ptrdiff_t, not Lisp_Object.  Adjust commentary for ‘next’ and
        ‘index’, which no longer contain nil.
        (HASH_NEXT, HASH_INDEX): Move to src/fns.c.

        Fix build failure caused by ‘Generate upcase and downcase tables from Unicode’

        The [5ec3a584: Generate upcase and downcase tables from Unicode data]
        commit broke bootstrap from a truly clean tree (e.g. a fresh clone or
        one created with ‘make extraclean’), see
        <https://hydra.nixos.org/build/48774928>.

        The failure was caused by characters.el trying to read Unicode
        property tables which aren’t available so early in the build process.

        Wrap the part that requires Unicode property tables in a condition
        checking if those are available.  If they aren’t they case and syntax
        tables won’t be fully set but later on, the characters.el file will be
        evaluated again and this time with Unicode properties available so
        final Emacs ends up with the exact same case and syntax tables.

        casing: don’t assume letters are *either* upper- or lower-case  (bug#24603)

        A compatibility digraph characters, such as Dž, are neither upper- nor
        lower-case.  At the moment however, those are reported as upper-case¹
        despite the fact that they change when upper-cased.

        Stop checking if a character is upper-case before trying to up-case it
        so that title-case characters are handled correctly.  This fixes one of
        the issues mentioned in bug#24603.

        ¹ Because they change when converted to lower-case.  Notice an asymmetry
          in that for a character to be considered lower-case it must not be
          upper-case (plus the usual condition of changing when upper-cased).

        * src/buffer.h (upcase1): Delete.
        (upcase): Change to upcase character unconditionally just like downcase
        does it.  This is what upcase1 was.

        * src/casefiddle.c (casify_object, casify_region): Use upcase instead
        of upcase1 and don’t check !uppercasep(x) before calling upcase.

        downcase(x) and see if it changed.

        Use Unicode data to generate case tables instead of mostly repeating

        This reverts commit b6fa58072304c2a24f1fe8a0e06a4739a7f8211b.

        The debbugs syntax requires a package name

2017-02-07  Vibhav Pant  <vibhavp@gmail.com>

        Add tests for checking byte-switch code.

        * test/lisp/emacs-lisp/bytecomp-tests.el (bytecomp-cond): New test,
          test byte-switch bytecode.

2017-02-07  Mark Oteiza  <mvoteiza@udel.edu>

        Add xdg library

        * etc/NEWS: Mention new library.
        * lisp/xdg.el: New file.

2017-02-07  Paul Eggert  <eggert@cs.ucla.edu>

        Do not trick info/dir’s timestamp

        * Makefile.in (${srcdir}/info/dir): When making this file, do not
        do anything special about its timestamp.  Previously this rule
        used move-if-change, which meant that this file’s timestamp could
        end up being older than the files it depends on, and this caused
        ‘make --question info’ to fail, which caused ‘make-dist’ to fail
        now that ‘make-dist’ invokes ‘make --question info’.

2017-02-07  Paul Eggert  <eggert@cs.ucla.edu>

        Make FOR_EACH_TAIL more like other FOR_EACH macros

        See comments by Stefan Monnier in:
        https://lists.gnu.org/r/emacs-devel/2017-02/msg00181.html
        and by Eli Zaretskii in:
        https://lists.gnu.org/r/emacs-devel/2017-02/msg00207.html
        * src/fns.c (internal_equal): Do not bypass check for depth
        overflow when tail-recursing via a dotted list tail or an overlay
        plist, to avoid a rare infloop.
        * src/lisp.h (FOR_EACH_TAIL, FOR_EACH_TAIL_SAFE): Take TAIL as an
        arg, and update it at each iteration, rather than have callers
        access it.tail.  All callers changed.
        (FOR_EACH_TAIL): Do not check for dotted lists, as this is now
        the caller’s responsibility.  All callers changed.
        (FOR_EACH_TAIL_CONS): Remove.  All callers changed.
        (struct for_each_tail_internal.tail): Remove; no longer needed.
        (FOR_EACH_TAIL_INTERNAL): Remove dotted arg, and set the tail
        arg each time through the loop.  All callers changed.

2017-02-05  Paul Eggert  <eggert@cs.ucla.edu>

        Port to clang 3.8.0

        It does not allow a for-loop's control var to be an anonymous struct.
        * src/lisp.h (struct for_each_tail_internal): New type.
        (FOR_EACH_TAIL_INTERNAL): Use it.

2017-02-05  Paul Eggert  <eggert@Penguin.CS.UCLA.EDU>

        Add cyclic-list tests

        * test/manual/cycle-tests.el: New file (Bug#25606).

2017-02-05  Paul Eggert  <eggert@Penguin.CS.UCLA.EDU>

        FOR_EACH_TAIL now checks for quit

        As per Eli Zaretskii (Bug#25606#20).  Although these calls to
        maybe_quit are unnecessary in practice, Eli was not convinced
        that the calls are unnecessary.
        * src/lisp.h (FOR_EACH_TAIL, FOR_EACH_TAIL_CONS):
        Call maybe_quit every so often.
        (FOR_EACH_TAIL_INTERNAL): New arg CHECK_QUIT.  All callers changed.

2017-02-05  Paul Eggert  <eggert@cs.ucla.edu>

        Signal list cycles in ‘length’ etc.

        Use macros like FOR_EACH_TAIL instead of maybe_quit to
        catch list cycles automatically instead of relying on the
        user becoming impatient and typing C-g (Bug#25606).
        * src/fns.c (Flength, Fmember, Fmemq, Fmemql, Fassq, Fassoc, Frassq)
        (Frassoc, Fdelete, Freverse):
        Use FOR_EACH_TAIL instead of maybe_quit.
        (Fnreverse): Use simple EQ to check for circular list instead
        of rarely_quit, as this suffices in this unusual case.
        (Fplist_put, Flax_plist_put, Flax_plist_put):
        Use FOR_EACH_TAIL_CONS instead of maybe_quit.
        (internal_equal): Use FOR_EACH_TAIL_CONS to check lists, instead
        of by-hand tail recursion that did not catch cycles.
        * src/fns.c (Fsafe_length, Fplist_get):
        * src/xdisp.c (display_mode_element):
        Use FOR_EACH_TAIL_SAFE instead of by-hand Floyd’s algorithm.
        * src/lisp.h (QUIT_COUNT_HEURISTIC): Remove; no longer needed.
        (rarely_quit): Simply count toward USHRT_MAX + 1, since the
        fancier versions are no longer needed.
        (FOR_EACH_TAIL_CONS, FOR_EACH_TAIL_SAFE)
        (FOR_EACH_TAIL_INTERNAL): New macros, the last with definiens
        mostly taken from FOR_EACH_TAIL.
        (FOR_EACH_TAIL): Rewrite in terms of FOR_EACH_TAIL_INTERNAL.

2017-02-05  Paul Eggert  <eggert@cs.ucla.edu>

        Simplify use of FOR_EACH_TAIL

        * src/data.c (circular_list): New function.
        * src/lisp.h (FOR_EACH_TAIL): Use Brent’s algorithm and C99 for-loop
        decl, to eliminate the need for the args TAIL, TORTOISE and N, and
        to speed things up a bit on typical hosts with optimization.
        All uses changed (Bug#25605).

2017-02-05  Simen Heggestøyl  <simenheg@gmail.com>

        * lisp/textmodes/css-mode.el: Require subr-x at compile time

2017-02-05  Eli Zaretskii  <eliz@gnu.org>

        Clarify documentation of 'bufferpos-to-filepos' and 'filepos-to-bufferpos'

        * doc/lispref/nonascii.texi (Text Representations): Clarify that
        'exact' value of QUALITY argument to 'bufferpos-to-filepos' and
        'filepos-to-bufferpos' can lead to expensive and slow processing.

        * lisp/international/mule-util.el (filepos-to-bufferpos)
        (bufferpos-to-filepos): Doc fix.  (Bug#25626)

2017-02-05  Vibhav Pant  <vibhavp@gmail.com>

        Merge remote-tracking branch 'origin/master' into feature/byte-switch

2017-02-05  Vibhav Pant  <vibhavp@gmail.com>

        bytecomp.el: Use macroexp-const-p instead of bc-cond-valid-obj2-p.

        * lisp/emacs-lisp/bytecomp.el (byte-compile-cond-vars): Use
          (macroexp-cons-p) instead of (byte-compile-cond-valid-obj2-p) to
          make sure that obj1/obj2 can be compared with `eq'.

2017-02-05  Vibhav Pant  <vibhavp@gmail.com>

        * lisp/emacs-lisp/byte-opt.el (byte-decompile-bytecode-1): Use eq instead of =.

2017-02-05  Vibhav Pant  <vibhavp@gmail.com>

        bytecomp.el: Inline lapcode containing `byte-switch' correctly.

        * lisp/emacs-lisp/bytecomp.el (byte-compile-inline-lapcode):
          Restore value of byte-compile-depth after emitting a jump to a tag
          in a jump table, or default/done tags.
          Set the depth of final tags for byte-switch to nil after emitting
          any jumps to them.

2017-02-05  Vibhav Pant  <vibhavp@gmail.com>

        byte-opt.el: Replace jump tables while decompiling correctly.

        * lisp/emacs-lisp/byte-opt.el (byte-decompile-bytecode-1):
          Don't make a copy of the constant vector, as it isn't used with
          the decompiled lapcode.
          Make sure that the correct lapcode pair/list is being modified while
          replacing the jump table.

2017-02-05  Vibhav Pant  <vibhavp@gmail.com>

        bytecomp.el: Don't store non-keyword symbols in jump-tables.

        * lisp/emacs-lisp/bytecomp.el (byte-compile-cond-valid-obj2-p) return
          nil when OBJ is a non-keyword symbol (i.e a variable), as the jump
          table can only be used when comparing variables with constant values.

2017-02-04  Tom Tromey  <tom@tromey.com>

        typo fix

        (css--colon-inside-selector-p): Fix typo in docstring.

2017-02-03  Paul Eggert  <eggert@cs.ucla.edu>

        Re-port alloc.c to Solaris sparc and simplify

        alloc.c had bitrotted a bit, and used an undefined symbol
        stack_base when Emacs was built on Solaris sparc, leading to
        compilation failures.  Also, code related to __builtin_unwind_init
        was unnecessarily duplicated.  Fix the bitrot and remove some
        duplication.
        * src/alloc.c: Remove uses of GC_SAVE_REGISTERS_ON_STACK, since it
        is never defined.
        (test_setjmp) [!HAVE___BUILTIN_UNWIND_INIT && GC_SETJMP_WORKS]:
        Define a no-op dummy, to simplify use.
        (test_setjmp) [!GC_SETJMP_WORKS]: Test setjmp_tested_p here rather
        than in the caller, to simplify use.
        (stacktop_sentry): New type.
        (__builtin_unwind_init) [!HAVE___BUILTIN_UNWIND_INIT]: New macro.
        (SET_STACK_TOP_ADDRESS): New macro, containing code that was duplicated.
        (flush_stack_call_func, Fgarbage_collect): Use it.
        (init_alloc): Omit unnecessary initialization.
        After dumping, Emacs need not re-test setjmp.

2017-02-03  Noam Postavsky  <npostavs@gmail.com>

        Add tests for scrolling

        * test/manual/scroll-tests.el: New tests for scroll-margin behavior.

2017-02-03  Noam Postavsky  <npostavs@gmail.com>

        Fix scrolling with partial lines

        * src/xdisp.c (partial_line_height): New function.
        (try_scrolling):
        * src/window.c (window_scroll_pixel_based): Use it for calculating the
        pixel scroll margin correctly in a window with partial lines.

2017-02-03  Noam Postavsky  <npostavs@gmail.com>

        Make limit on scroll-margin variable

        * src/xdisp.c (maximum-scroll-margin): New variable.
        * lisp/cus-start.el: Make it customizable.
        * etc/NEWS: Mention it.
        * doc/emacs/display.texi (Auto Scrolling):
        * doc/lispref/windows.texi (Textual Scrolling): Document it.
        * src/window.c (window_scroll_pixel_based): Use it instead of hardcoding
        division by 4 (Bug #5718).

2017-02-03  Noam Postavsky  <npostavs@gmail.com>

        Don't count mode line for scroll-margin limit

        * src/window.c (window_scroll_margin): Use window_box_height to avoid
        counting header line, scrollbars for scroll-margin limit (Bug #5718).

2017-02-03  Noam Postavsky  <npostavs@gmail.com>

        Refactor uses of scroll_margin to a function

        Its effective range needs to be clamped between 0 and (window height /
        4), so it's better to have this constraint in a single place.

        * src/window.c (window_scroll_margin): New function.
        (window_scroll_pixel_based, window_scroll_line_based):
        (Frecenter, Fmove_to_window_line):
        * src/xdisp.c (try_scrolling, try_cursor_movement):
        (redisplay_window, try_window, try_window_id): Use it.

2017-02-03  Dmitry Gutov  <dgutov@yandex.ru>

        (xref-collect-matches): Use '-E' together with '-e'

        * lisp/progmodes/xref.el (xref-collect-matches): Use '-E'
        together with '-e', as suggested by Noam Postavsky
        (https://lists.gnu.org/r/emacs-devel/2017-01/msg00780.html).

2017-02-02  Paul Eggert  <eggert@cs.ucla.edu>

        Fix lisp.h underparenthesization

        * src/lisp.h (STACK_CONS, AUTO_STRING_WITH_LEN):
        Parenthesize compound literals that are function call args.
        Although this does not fix any bugs, it is the proper style for
        macro parenthesization as it means this code will continue to
        work even if make_lisp_ptr is changed to a macro.

2017-02-02  Stefan Monnier  <monnier@iro.umontreal.ca>

        * lisp/doc-view.el (doc-view-mode): Don't require a final newline

        (doc-view-revert-buffer): Silence overflow warnings.

        Prevent creating thumbnails of all gif frames

        With the previous defaults, doing image-dired on a directory with an
        animated foo.gif would cause creation of foo.thumb-N.gif for each of
        N frames in foo.gif.  By default image-dired looks for foo.thumb.gif, so
        there additionally is no usable thumbnail after all the needless effort.
        image-dired never handled animation, regardless.

        Fix quitting bug when buffers are frozen

        Problem noted by Eli Zaretskii in:
        https://lists.gnu.org/r/emacs-devel/2017-01/msg00721.html
        This patch also fixes some other issues in that report.
        * src/lisp.h (incr_rarely_quit): Remove.
        All callers changed to use rarely_quit directly.
        * src/search.c (freeze_buffer_relocation)
        (thaw_buffer_relocation): New functions.
        (looking_at_1, fast_looking_at, search_buffer):
        Use them to fix bug when quitting when buffers are frozen.
        * src/sysdep.c (emacs_intr_read): Rename from emacs_nointr_read.
        All uses changed.

2017-02-02  Paul Eggert  <eggert@cs.ucla.edu>

        Revamp quitting and fix infloops

        This fixes some infinite loops that cannot be quitted out of,
        e.g., (defun foo () (nth most-positive-fixnum '#1=(1 . #1#)))
        when byte-compiled and when run under X.  See:
        https://lists.gnu.org/r/emacs-devel/2017-01/msg00577.html
        This also attempts to keep the performance improvements I recently
        added, as much as possible under the constraint that the infloops
        must be caught.  In some cases this fixes infloop bugs recently
        introduced when I removed immediate_quit.
        * src/alloc.c (Fmake_list):
        Use rarely_quit, not maybe_quit, for speed in the usual case.
        * src/bytecode.c (exec_byte_code):
        * src/editfns.c (Fcompare_buffer_substrings):
        * src/fns.c (Fnthcdr):
        * src/syntax.c (scan_words, skip_chars, skip_syntaxes)
        (Fbackward_prefix_chars):
        Use rarely_quit so that users can C-g out of long loops.
        * src/callproc.c (call_process_cleanup, call_process):
        * src/fileio.c (read_non_regular, Finsert_file_contents):
        * src/indent.c (compute_motion):

        Remove now-unnecessary maybe_quit calls.
        * src/callproc.c (call_process):
        * src/doc.c (get_doc_string, Fsnarf_documentation):

        * src/lread.c (safe_to_load_version):
        * src/sysdep.c (system_process_attributes) [GNU_LINUX]:
        Use emacs_read_quit instead of emacs_read in places where
        C-g handling is safe.
        * src/eval.c (maybe_quit): Move comment here from lisp.h.
        * src/fileio.c (Fcopy_file, e_write):
        Use emacs_write_quit instead of emacs_write_sig in places where
        C-g handling is safe.
        * src/filelock.c (create_lock_file): Use emacs_write, not
        plain write, as emacs_write no longer has a problem.
        (read_lock_data): Use emacs_read, not read, as emacs_read
        no longer has a problem.
        * src/fns.c (rarely_quit): Move to lisp.h and rename to
        incr_rarely_quit.  All uses changed..
        * src/fns.c (Fmemq, Fmemql, Fassq, Frassq, Fplist_put, Fplist_member):
        * src/indent.c (compute_motion):
        * src/syntax.c (find_defun_start, back_comment, forw_comment)
        (Fforward_comment, scan_lists, scan_sexps_forward):
        Use incr_rarely_quit so that users can C-g out of long loops.
        * src/fns.c (Fnconc): Move incr_rarely_quit call to within
        inner loop, so that it catches C-g there too.
        * src/keyboard.c (tty_read_avail_input): Remove commented-out
        and now-obsolete code dealing with interrupts.
        * src/lisp.h (rarely_quit, incr_rarely_quit): New functions,
        the latter moved here from fns.c and renamed from rarely_quit.
        (emacs_read_quit, emacs_write_quit): New decls.
        * src/search.c (find_newline, search_buffer, find_newline1):
        Add maybe_quit to catch C-g.
        * src/sysdep.c (get_child_status): Always invoke maybe_quit
        if interruptible, so that the caller need not bother.
        (emacs_nointr_read, emacs_read_quit, emacs_write_quit):
        New functions.
        (emacs_read): Rewrite in terms of emacs_nointr_read.
        Do not handle C-g or signals; that is now for emacs_read_quit.
        (emacs_full_write): Replace PROCESS_SIGNALS two-way arg
        with INTERRUPTIBLE three-way arg.  All uses changed.

2017-02-02  Paul Eggert  <eggert@cs.ucla.edu>

        Remove immediate_quit.

        The old code that sets and clears immediate_quit was
        ineffective except when Emacs is running in terminal mode, and
        has problematic race conditions anyway, so remove it.  This
        will introduce some hangs when Emacs runs in terminal mode,
        and these hangs should be fixed in followup patches.
        * src/keyboard.c (immediate_quit): Remove.  All uses removed.

2017-02-01  Alan Mackenzie  <acm@muc.de>

        Allow C++ nested brace-list-entries to be better indented.

        This fixes bug #24431.  The key change of this bug fix is correctly analyzing
        nested brace lists when the opening element stands on the same line as both
        its introductory brace and an enclosing parameter list parenthesis.

        * lisp/progmodes/cc-align.el (c-lineup-under-anchor): New line-up function.

        * lisp/progmodes/cc-engine.el (c-looking-at-or-maybe-in-bracelist): Accept the
        presence of exactly an identifier between an open parenthesis and an open
        brace as evidence of the brace starting a brace list.
        (c-looking-at-statement-block): New function, extracted from
        c-looking-at-inexpr-block.  Enhance it to analyze inner blocks recursively
        when needed.
        (c-looking-at-inexpr-block): Extract new function (see above) and call it.
        (c-add-stmt-syntax): Enhance, with new &optional parameter, to supply the
        prime syntactic symbol with a fixed anchor point.  When this is used, restrict
        all added syntactic symbols to those having an anchor point on the same line.
        Add, in addition to the current additional symbols, c-brace-list-entry when
        needed; use c-looking-at-statement-block to determine the latter.
        (c-guess-basic-syntax, CASE 9D): Use c-add-stmt-syntax rather than just
        c-add-syntax, to assemble the syntactic context of a 'brace-list-entry, thus
        getting, possibly, several accompanying syntactic entries.

        * lisp/progmodes/cc-styles.el (c-style-alist, "gnu" style): New entry for
        'brace-list-intro, namely c-lineup-arglist-intro-after-paren.

        * lisp/progmodes/cc-vars.el (c-offsets-alist): Change the factory default
        offset for 'brace-list-entry from 0 to c-lineup-under-anchor.

        * doc/misc/cc-mode.texi (Syntactic Symbols): Amend the definition of
        brace-list-intro.
        (Brace List Symbols): Amend the example to show the new analysis of brace
        lists when the first element comes on the same line as the opening brace.
        (Misc Line-Up): Document the new line-up function c-lineup-under-anchor.

        Replace QUIT with maybe_quit

        There’s no longer need to have QUIT stand for a slug of C statements.
        Use the more-obvious function-call syntax instead.
        Also, use true and false when setting immediate_quit.
        These changes should not affect the generated machine code.
        * src/lisp.h (QUIT): Remove.  All uses replaced by maybe_quit.

2017-01-26  Paul Eggert  <eggert@cs.ucla.edu>

        A quicker check for quit

        On some microbenchmarks this lets Emacs run 60% faster on my
        platform (AMD Phenom II X4 910e, Fedora 25 x86-64).
        * src/atimer.c: Include keyboard.h, for pending_signals.
        * src/editfns.c (Fcompare_buffer_substrings):
        * src/fns.c (Fnthcdr, Fmemq, Fmemql, Fassq, Frassq, Fplist_put)
        (Fnconc, Fplist_member):
        Set and clear immediate_quit before and after loop instead of
        executing QUIT each time through the loop.  This is OK for loops
        that affect only locals.
        * src/eval.c (process_quit_flag): Now static.
        (maybe_quit): New function, containing QUIT’s old body.
        * src/fns.c (rarely_quit): New function.
        (Fmember, Fassoc, Frassoc, Fdelete, Fnreverse, Freverse)
        (Flax_plist_get, Flax_plist_put, internal_equal, Fnconc):
        Use it instead of QUIT, for
        speed in tight loops that might modify non-locals.
        * src/keyboard.h (pending_signals, process_pending_signals):
        These belong to keyboard.c, so move them here ...
        * src/lisp.h: ... from here.
        (QUIT): Redefine in terms of the new maybe_quit function, which
        contains this macro’s old definiens.  This works well with branch
        prediction on processors with return stack buffers, e.g., x86
        other than the original Pentium.

        the loop could sometimes before the frame turned visible, and for some

        Check if the point is inside a diff header, in the middle of a hunk,
        or before the first hunk.

        with all the guts of lisp_mutex_lock.

        (condition_wait_callback): Don't call post_acquire_global_lock
        before locking the mutex, as that could cause a signaled thread to
        exit prematurely, because the condvar's mutex is recorded to be
        not owned by any thread, and with-mutex wants to unlock it as part
        of unwinding the stack in response to the signal.

        setting to nil is now supported.
        (ffap--gopher-var-on-line): New function.
        (ffap-gopher-at-point): Use it instead of the old ffap-gopher-regexp

        * lisp/emacs-lisp/bytecomp.el: Add documentation, remove code duplication

2017-01-14  Vibhav Pant  <vibhavp@gmail.com>

        Add new 'switch' byte-code.

        'switch' takes two arguments from the stack: the variable to test, and
        a jump table (implemented as a hash-table with the appropriate :test
        function). By looking up the value of the variable in the hash table,
        the interpreter can jump to the label pointed to by the value, if any.
        This implementation can only be used for `cond' forms of the type
        `(cond ((test x 'foo) 'bar) ...)`, such that the function `test` and
        variable `x` is same for all clauses.

        * lisp/emacs-lisp/bytecomp.el:

          * Add (byte-compile-cond-valid-obj2-p), (byte-compile-cond-vars),
            (byte-compile-cond-jump-table-info), (byte-compile-jump-table-add-tag),
            (byte-compile-cond-jump-table), byte-compile-jump-tables.

          * Add defcustom `byte-compile-cond-use-jump-table'.

          * (byte-compile-cond): Use them.

          * (byte-compile-lapcode): Patch tags present in jump tables, if any.

        * lisp/emacs-lisp//byte-opt.el: (byte-optimize-lapcode): Add checks to
          some peephole optimizations to prevent them from messing up any code
          involving `byte-switch`.

        * src/bytecode.c: (exec_byte_code): Add bytecode Bswitch.

2017-01-14  Alan Mackenzie  <acm@muc.de>

        Correct c-parse-state-get-strategy for moving HERE backward into a macro.

        * lisp/progmodes/cc-engine.el (c-parse-state-get-strategy): When HERE is below
        its previous value, we chose strategy 'forward, and the new HERE is in a
        (different) macro, ensure the returned START-POINT is not above the start of
        the macro.

        add the date, but the composed message body doesn't have it.

        Previously, autoloads were collected till loaddefs.el was generated as
        part of the build. However, bootstrap-emacs does not load
        loaddefs (rather it is dumped), hence we must record autoloads until the
        full emacs binary is dumped.

        Use expanded stack during regex matches

        While the stack is increased in main(), to allow the regex stack
        allocation to use alloca we also need to modify regex.c to actually take
        advantage of the increased stack, and not limit stack allocations to
        SAFE_ALLOCA bytes.

        * src/regex.c (MATCH_MAY_ALLOCATE): Remove obsolete comment about
        allocations in signal handlers which no longer happens and correct
        description about when and why MATCH_MAY_ALLOCATE should be defined.
        (emacs_re_safe_alloca): New variable.
        (REGEX_USE_SAFE_ALLOCA): Use it as the limit of stack allocation instead
        of MAX_ALLOCA.
        (emacs_re_max_failures): Rename from `re_max_failures' to avoid
        confusion with glibc's `re_max_failures'.
        * src/emacs.c (main): Increase the amount of fixed 'extra' bytes we add
        to the stack.  Instead of changing emacs_re_max_failures based on the
        new stack size, just change emacs_re_safe_alloca; emacs_re_max_failures
        remains constant regardless, since if we run out stack space SAFE_ALLOCA
        will fall back to heap allocation.

        Fix computation of regex stack limit

        The regex stack limit was being computed as the number of stack entries,
        whereas it was being compared with the current size as measured in
        bytes.  This could cause indefinite looping when nearing the stack limit
        if re_max_failures happened not to be a multiple of sizeof
        fail_stack_elt_t (Bug #24751).

        * src/regex.c (GROW_FAIL_STACK): Compute both current stack size and
        limit as numbers of stack entries.

        Fix term.el handling of ^Z-sequences spanning chunks

        Bash will after each command send ?\032 and the current directory "/tmp"
        to inform term.el.  Bash output is buffered in 4096 bytes chunks.  If a

        Warn about incomplete untarring of link files

        The current tar-mode doesn't really support unpacking symlinks, it
        simply creates an empty file of the same name.

        * lisp/tar-mode.el (tar--describe-as-link): New function extracted from
        `tar--check-descriptor'.
        (tar-untar-buffer): Use it to warn about imperfectly untarred link
        files.

        Since tmux version 2.1, new tmux terminfos are shipped due to oddities
        with xterm and screen terminfos.  This is simply a duplication of
        term/screen.el with screen -> tmux.
        * lisp/term/tmux.el: New file.

        Fix encoding of JSON surrogate pairs

        JSON requires that such pairs be treated as UTF-16 surrogate pairs, not
        individual code points; cf. Bug #24784.

        * lisp/json.el (json-read-escaped-char): Fix decoding of surrogate
        pairs.
        (json--decode-utf-16-surrogates): New defun.

        Clarify internal_catch etc.

        The recent change to internal_catch and friends relied on some
        confusion I introduced to the code in 2013.  Attempt to fix
        the confusion by clarifying the code instead.  This saves an
        instruction and a load dependency in the typical case.
        * src/eval.c (internal_catch, internal_condition_case)
        (internal_condition_case_1, internal_condition_case_2)
        (internal_condition_case_n): Undo the previous change.  Instead,
        use use ‘c’ rather than ‘handlerlist’ in the typical case.
        Also, use ‘eassert’ rather than ‘clobbered_eassert’ when possible.

2016-12-31  Ken Brown  <kbrown@cornell.edu>

        Further improve filenotify-tests.el

        GFamFileMonitor, which occur on Cygwin.
        (file-notify--test-monitor): Update doc string.

        * src/nsterm.m (unwind_apploopnr): Remove.
        (ns_read_socket): Remove references to apploopnr.  Make processing the
        NS event loop conditional on being in the main thread.
        (ns_select): Remove references to apploopnr.  Remove all fd_handler
        related stuff.  Check if there are events waiting on the NS event
        queue rather than running the event loop.  Remove unused variables and
        code.
        (fd_handler): Remove.
        (ns_term_init): Remove creation of fd_handler thread.
        (hold_event, EmacsApp:sendEvent, EmacsView:mouseMoved,
        EmacsView:windowDidExpose): Remove send_appdefined.
        (ns_send_appdefined): Always check the event queue for
        applicationDefined events rather than relying on send_appdefined var.
        * src/nsterm.h: Remove reference to fd_handler method.

        Checkdoc: use syntax functions instead of regex

        In checkdoc.el, get rid of the error-prone regex to find definition
        forms, and use existing syntax-based navigation functions instead.
        This fixes a corner case with one-argument `defvar' forms.

        * lisp/emacs-lisp/checkdoc.el (checkdoc--next-docstring): New function.
        (checkdoc-next-docstring, checkdoc-defun): Use it.
        * test/lisp/emacs-lisp/checkdoc-tests.el (checkdoc-tests--next-docstring):

        Don't define NOMINMAX on MS-Windows

        * src/callproc.c (NOMINMAX) [WINDOWSNT]: Don't define.  This is no
        longer needed with the current sources and MinGW headers, while
        defining NOMINMAX causes an annoying compiler warning.

2016-12-31  Chris Gregory  <czipperz@gmail.com>  (tiny change)

        (internal_condition_case_n): Factor out the common tail of the

        (random): Use it instead of MS runtime's 'rand'.  This avoids
        producing separate and identical random series in each Lisp
        thread.
        (srandom): Modify to supply 3 seed values to 'rand_as183'.

        In a typical GNU/Linux/X11 build, we wind up with over 15k symbols by
        the time we've started.  The old obarray size ensured an average chain
        length of 10 or more.

        * src/lread.c (OBARRAY_SIZE): Increase to 15121.

2016-12-30  Ken Raeburn  <raeburn@raeburn.org>

        Initialize thread support for Xlib.

        * src/xterm.c (x_initialize) [THREADS_ENABLED]: Call XInitThreads

2016-12-30  Paul Eggert  <eggert@cs.ucla.edu>

        Rename primary_thread to main_thread

        This avoids the confusion of using two different phrases "main thread"
        and "primary thread" internally to mean the same thing.  See:
        https://lists.gnu.org/r/emacs-devel/2016-12/msg01142.html
        * src/thread.c (main_thread): Rename from primary_thread,
        since the new name no longer clashes with main_thread_id
        and Emacs internals normally call this the "main thread".
        (init_main_thread): Rename from init_primary_thread.
        (main_thread_p): Rename from primary_thread_p.
        All uses changed.

2016-12-30  Paul Eggert  <eggert@cs.ucla.edu>

        Rename main_thread to main_thread_id and simplify

        * src/emacs-module.c: Include syssignal.h, for main_thread_id.
        [HAVE_PTHREAD]: Do not include pthread.h.
        (main_thread): Remove.  All uses replaced by main_thread_id,
        or by dwMainThreadId on NT.  Since the HAVE_PTHREAD code is now using
        the main_thread_id established by sysdep.c, there is no need for a
        separate copy of the main thread ID here.
        (module_init): Remove.  All uses removed.
        * src/sysdep.c (main_thread_id) [HAVE_PTHREAD]:
        Rename from main_thread.  All uses changed.  Now extern.

2016-12-30  Michael Albinus  <michael.albinus@gmx.de>

        * src/gfilenotify.c (Fgfile_monitor_name): Return a symbol.

        * src/sysdep.c (deliver_process_signal): Improve comment.

2016-12-30  Alan Mackenzie  <acm@muc.de>

        CC Mode: Fix the fontification of a spuriously recognized enum member.

        The "enum" was in an argument list, but triggered the fontification of a
        following identifier in the function block as though it were in an enum
        declaration.

        * lisp/progmodes/cc-fonts.el (c-font-lock-enum-body): New function.
        (c-basic-matchers-after): Replace the inline stanza for enum elements with a
        call to c-font-lock-enum-body.

        * lisp/progmodes/cc-langs.el (c-enum-clause-introduction-re): New language
        variable.

        * lisp/ldefs-boot.el: Update.

2016-12-30  Eli Zaretskii  <eliz@gnu.org>

        Attempt to fix crashes with threads in GTK builds

        * src/xgselect.c (xg_select): Call pselect via thread_select, not
        directly, to avoid running Lisp (via unblock_input) when more than
        one thread could be running.  (Bug#25247)
        * src/process.c (wait_reading_process_output) [HAVE_GLIB]: Call
        xg_select directly instead of through thread_select.
        * src/xgselect.h (xg_select): Last 2 arguments are no longer
        'const', for consistency with thread_select.

2016-12-30  Arash Esbati  <arash.esbati@gmail.com>

        Backport: Remove an ambiguity from defvar's doc string.  Fixes bug #25292.

        The ambiguity was whether INITVALUE is evaluated when it's not going to be

        * src/eval.c (defvar): Rewrite a paragraph of the doc string.

        Partially correct fontification of "(b*3)", and the like, in C++ Mode

        This problem is caused by the fundamental ambiguity in C++ between

        This is because there are times when this variable is changed by setcar before
        an atom is pushed onto it by debug-enter.  This happens, for example, whilst
        instrumenting c-font-lock-declarations in .../lisp/progmodes/cc-fonts.el.

        * lisp/emacs-lisp/edebug.el (edebug-offset-indices): initialize to '(0).

        Inspired by a suggestion from Chris Gregory in:

        On my platform, this generates exactly the same machine insns.

2016-12-25  Paul Eggert  <eggert@cs.ucla.edu>

        Reorder lisp.h to declare types before using them

        This puts basic functions for types to be after the corresponding
        type definitions.  This is a more-common programming style in C,
        and will make it easier to port Emacs to gcc
        -fcheck-pointer-bounds, since the functions now have access to the
        corresponding types' sizes.  This patch does not change the code;
        it just moves declarations and definitions and removes
        no-longer-needed forward declarations (Bug#25128).
        * src/buffer.c, src/data.c, src/image.c:
        Include process.h, for PROCESSP.
        * src/buffer.h (BUFFERP, CHECK_BUFFER, XBUFFER):

        * src/thread.h (THREADP, CHECK_THREAD, XTHREAD, MUTEXP, CHECK_MUTEX)
        (XMUTEX, CONDVARP, CHECK_CONDVAR, XCONDVAR):
        Move here from lisp.h.
        * src/intervals.h: Include buffer.h, for BUFFERP.
        Include lisp.h, for Lisp_Object.
        * src/lisp.h: Reorder declarations and definitions as described
        above.  Move thread includes to be later, so that they can use the
        reordered definitions.  Move some symbols to other headers (noted
        elsewhere).  Remove forward decls that are no longer needed.
        * src/thread.h: Include systhread.h here, not in lisp.h,
        since lisp.h itself does not need systhread.h.

        diff-mode auto-refines only after a successful motion

        Prior to this patch (if enabled) auto-refinement would kick in after all
        hunk navigation commands, even if the motion failed.  This would result
        in a situation where the hunk navigation would signal an error and beep,
        but yet still accomplish potentially useful work, by auto-refining.
        This patch moves the auto-refinement code to only run when a motion was
        successful

        * lisp/vc/diff-mode.el (diff--internal-hunk-next,
          diff--internal-hunk-prev): Removed auto-refinement-triggering code

        diff-mode is able to better handle file headers

        This fixes a regression introduced in

          https://git.savannah.gnu.org/gitweb/?p=emacs.git;a=commit;h=2c8a7e50d24daf19ea7d86f1cfeaa98a41c56085

          https://debbugs.gnu.org/cgi/bugreport.cgi?bug=25105

        Patches generated from a VCS such as git contain a patch message at the
        start, and diff-mode is now once-again able to properly able to ignore
        this message when issuing navigation commands around the message.

        * lisp/vc/diff-mode.el (diff-beginning-of-file-and-junk): More

        There were some functions in verilog-mode that implemented in-buffer

        Improve default load-path for uninstalled CANNOT_DUMP builds

        * src/lread.c (load_path_default) [CANNOT_DUMP]:
        Use build load-path if we seem to be running uninstalled.  (Bug#24974)
        I think this became an issue several years ago when we stopped
        using EMACSLOADPATH in the Makefiles; however this change should
        improve the CANNOT_DUMP uninstalled case in general.

        Add a new compile error regexp for Clang includes

        Clang uses a slight variation of GCC's include format, causing includes
        to be treated as warnings instead of informational messages.  Use a new
        regular expression instead.

        * lisp/progmodes/compile.el

        Use floor of mtime instead of rounding for thumb property

        This seems to be the correct thing to do, at least more in line with
        what at least one other implementation does.  Anything using
        gnome-desktop [0] effectively does the same, as
        gnome_desktop_thumbnail_is_valid applies atol(3) to mtime for
        comparison and time_t on GNU/Linux is a signed int.
        [0] https://git.gnome.org/browse/gnome-desktop/
        * lisp/image-dired.el (image-dired-create-thumb): Use floor here.

        * lisp/desktop.el (desktop-restoring-frameset-p): Test for the GUI
        frame here, instead of in desktop-restoring-frameset.  That's
        because desktop-read wants to know whether frameset will actually
        be restored, and has fallback procedures up its sleeve when it
        won't be; these fallbacks need to be invoked when the frameset is
        not going to be restored.  (Bug#24298)

2016-12-17  Eli Zaretskii  <eliz@gnu.org>

        Fix crashes on MS-Windows during dumping

        * src/unexw32.c (get_section_info): Make extra_bss_size be the
        maximum of extra_bss_size and extra_bss_size_static.  This avoids
        computing the size of the output file smaller than it actually
        needs to be, which then causes copy_executable_and_dump_data to
        write beyond the requested size of the file mapping, thus relying
        on the OS roundup to page boundary to save us from ourselves.  See
        https://lists.gnu.org/r/emacs-devel/2016-12/msg00642.html
        for the details.

        automatically set image-dired-thumb-width and image-dired-thumb-height.

        Prevent crashes in xg_select due to concurrency

        * src/xgselect.c (xg_select): Don't call Glib functions that use
        'context' if we failed to acquire it.  This means some other
        thread owns the context, in which case both using the context and
        calling block_input/unblock_input will step on that thread's toes
        and eventually lead to crashes.  (Bug#25172)

2016-12-15  Nicolas Petton  <nicolas@petton.fr>

        Fix circular list handling in seq-mapn

        Reset window scroll when displaying an image

        When viewing a large image full size and scrolling, for instance, to
        the lower right corner, then selecting a much smaller image in the
        thumbnail buffer, the window stays scrolled so the new image is out of
        the window.  One must scroll back to the "origin" to view the new
        displayed image, or just kill the image-dired-display-image buffer and
        try again.  This fixes the issue.
        * lisp/image-dired.el (image-dired-display-window-width):
        (image-dired-display-window-height): Operate on a window as argument.
        (image-dired-display-image): Bind (image-dired-display-window) and use
        it. Set window vscroll and hscroll to zero when refreshing the
        buffer's contents.

2016-12-14  Mark Oteiza  <mvoteiza@udel.edu>

        More image-dired polish

        * lisp/image-dired.el (image-dired-file-name-at-point): New function.
        (image-dired-thumbnail-mode, image-dired-display-image-mode): Disable
        undo list. Add image-dired-file-name-at-point to
        file-name-at-point-functions to facilitate find-file and friends.
        (image-dired-thumbnail-display-external):
        (image-dired-dired-display-external): Use start-process instead, to
        avoid needlessly blocking and using a shell.

2016-12-13  Phillip Lord  <phillip.lord@russet.org.uk>

        Replace ldefs-boot with a much smaller file

         * Makefile.in (bootstrap-build,generate-ldefs-boot): New targets.

        lisp/textmodes/ispell.el (ispell-check-version): Require Aspell 0.60.
        (ispell-aspell-dictionary-alist): Remove check that we have Aspell 0.60.

2016-12-13  Reuben Thomas  <rrt@sc3d.org>

        Minor docstring and comment fixes to ispell.el

        lisp/textmodes/ispell.el (ispell-aspell-dictionary-alist): Mention
        ispell-aspell-dictionary-alist, not ispell-dictionary-alist.
        (ispell-set-spellchecker-params): Change double-single quotes to
        single single quotes in comment.

2016-12-13  Reuben Thomas  <rrt@sc3d.org>

        (ispell-command-loop, ispell-message): Use with-no-warnings directly.

2016-12-13  Reuben Thomas  <rrt@sc3d.org>

        Remove meaningless defconst ispell-version

        * lisp/textmodes/ispell.el (ispell-version): Since ispell.el is now
        firmly part of Emacs, and the version hasn’t changed since 2003, and
        isn’t used anywhere, remove it.  3rd-party code can better use the
        Emacs version, or feature or function checks.
        (ispell-check-version): No longer report ispell.el version.

2016-12-13  Reuben Thomas  <rrt@sc3d.org>

        Remove boundp test for always-bound symbol

        * lisp/textmodes/ispell.el (ispell-message): mail-yank-prefix is

        bound.

2016-12-13  Reuben Thomas  <rrt@sc3d.org>

        Remove support for ispell < 3.1.12

        * lisp/textmodes/ispell.el (ispell-offset): Remove.

        (ispell-process-line): No longer use ispell-offset.

2016-12-13  Reuben Thomas  <rrt@sc3d.org>

        Remove support for old versions of supercite and GNUS from ispell.el

        * lisp/textmodes/ispell.el (ispell-message): Require supercite >= 3.0
        and GNUS >= 5.  Not exactly the bleeding edge!

        ispell-valid-dictionary-list): Remove commented-out code.

2016-12-13  Reuben Thomas  <rrt@sc3d.org>

        Remove XEmacs and old Emacs highlighting code

        * lisp/textmodes/ispell.el
        (ispell-highlight-spelling-error-xemacs): Remove.

2016-12-13  Reuben Thomas  <rrt@sc3d.org>

        Assume Emacs supports [:alpha:] in regexps

        * lisp/textmodes/ispell.el (ispell-emacs-alpha-regexp): Remove.
        (ispell-set-spellchecker-params): Remove tests of
        ispell-emacs-alpha-regexp.

        Generalize over-specific documentation

        * lisp/textmodes/ispell.el (ispell-personal-dictionary): Rather than
        document precise personal wordlist filenames for only two supported
        spelling checkers, simply say that the default personal dictionary
        depends on the chosen spelling checker.  The user can check the
        spelling checker’s documentation if necessary.  This is simpler, and
        works for other supported (and future, or unknown) spelling checkers.

2016-12-13  Reuben Thomas  <rrt@sc3d.org>

        Remove tests for built-in functions

        * lisp/textmodes/ispell.el (buffer-substring-no-properties): Remove

2016-12-13  Reuben Thomas  <rrt@sc3d.org>

        Assume we have version<= for checking ispell version

        * lisp/textmodes/ispell.el (ispell-check-minver): Remove.
        (ispell-check-version): Use version<= directly.

2016-12-13  Reuben Thomas  <rrt@sc3d.org>

        Remove ispell.el pre-GNU Emacs comments

        * lisp/textmodes/ispell.el (Commentary): Remove original maintainer
          details, as Emacs version, bug report address and so forth should be
          used instead for this version.  Remove in-line change history; use
          git instead.

2016-12-13  Mark Oteiza  <mvoteiza@udel.edu>

        node.
        (image-dired--with-db-file): Add declare forms.
        (image-dired-hidden-p): Rewrite with cl-loop.  It's not necessary to
        run through the whole list.

2016-12-13  Mark Oteiza  <mvoteiza@udel.edu>

        Remove image-dired-kill-buffer-and-window

        This breaks window layout, especially when quitting a
        image-dired-display-image-mode buffer.
        * lisp/image-dired.el (image-dired-thumbnail-mode-map):
        (image-dired-display-image-mode-map): Replace in keymap and menu items
        bindings to image-dired-kill-buffer-and-window with quit-window.
        (image-dired-kill-buffer-and-window): Remove.

2016-12-13  Mark Oteiza  <mvoteiza@udel.edu>

        Replace image-dired-setup-dired-keybindings with a minor mode

        * lisp/image-dired.el (image-dired-thumbnail-mode): Fix docstring to
        remove mention of nonexistent image-dired-dired and to refer to the
        new minor mode.
        (image-dired-minor-mode-map): New keymap assimilated from
        image-dired-setup-dired-keybindings.  In the future, the keymap parent
        should be removed, and perhaps also the duplicate bindings that
        already exist in dired-mode-map.
        (image-dired-setup-dired-keybindings): Remove.  Replace with an
        obsolete function alias.
        (image-dired-minor-mode): New minor mode, assuming the role of
        image-dired-setup-dired-keybindings.

2016-12-13  Paul Eggert  <eggert@cs.ucla.edu>

        Clean up var watcher disabling on thread switching

        * src/data.c (Fset_default): Move code into new C level function,
        `set_default_internal'.
        (set_default_internal): New function, like `Fset_default' but also takes
        additional bindflag parameter.
        (set_internal): Only call `notify_variable_watchers' if bindflag is not
        SET_INTERNAL_THREAD_SWITCH.
        * src/eval.c (do_specbind, do_one_unbind): Add bindflag parameter,
        passed on to set_internal and set_default_internal.  Adjust callers.

        SET_INTERNAL_THREAD_SWITCH to do_specbind, do_one_unbind instead of
        temporarily adjusting symbol's trapped_write field.

        Minor fix for define-derived-mode

        * lisp/emacs-lisp/derived.el (define-derived-mode):

        (get_backtrace_frame, Fbacktrace_debug): Use `get_backtrace_starting_at'.

        * lisp/subr.el (backtrace--print-frame): New function.
        (backtrace): Reimplement using `backtrace--print-frame' and `mapbacktrace'.
        (backtrace-frame): Reimplement using `backtrace-frame--internal'.

        * lisp/emacs-lisp/debug.el (debugger-setup-buffer): Pass a base to
        `mapbacktrace' instead of searching for "(debug" in the output of
        `backtrace'.

        (subr-test-backtrace-integration-test): New tests.

        * doc/lispref/debugging.texi (Internals of Debugger): Document

        Minor advice.el fix

        * lisp/emacs-lisp/advice.el (ad-preactivate-advice):
        Avoid setting the function definition of nil.
        This was happening during bootstrap of org-compat.el,
        apparently due to eager macro expansion of code behind
        a (featurep 'xemacs) test.

2016-12-12  Eli Zaretskii  <eliz@gnu.org>

        Make etags-tests work in out-of-tree builds

        * test/lisp/progmodes/etags-tests.el (etags-bug-158)

        Avoid crashing if a new thread is signaled right away

        * src/thread.c (post_acquire_global_lock): Don't raise the pending
        signal if the thread's handlers were not yet set up, as that will
        cause Emacs to exit with a fatal error.  This can happen if a
        thread is signaled as soon as make-thread returns, before the new
        thread had an opportunity to acquire the global lock, set up the
        handlers, and call the thread function.

        Fix point motion in cloned buffers

        * src/thread.c (post_acquire_global_lock): Call
        set_buffer_internal_2 instead of tricking set_buffer_internal_1
        into resetting the current buffer even if it didn't change.  This
        avoids bug#25165, caused by failing to record the modified values
        of point and mark, because current_buffer was set to NULL.  Also,
        don't bother re-setting the buffer if there was no thread switch,
        as that just wastes cycles.
        * src/buffer.c (set_buffer_internal_2): New function, with most of
        the body of set_buffer_internal_1, but without the test for B
        being identical to the current buffer.
        (set_buffer_internal_1): Call set_buffer_internal_2 if B is not
        identical to the current buffer.
        * src/buffer.h (set_buffer_internal_2): Add prototype.

        * test/src/thread-tests.el (thread-sticky-point): New test.

        When in a directory named '~', the default value given by
        `read-file-name' should be quoted by prepending '/:', in order to

        Define struct predicate before acccesors

        The accessor functions use the predicate function, which causes problems
        when reloading after unload-feature: the compiler-macro property is
        still present on the predicate symbol, and the compiler fails to find
        the definition when trying to inline it into the accessor
        function (Bug#25088).

        * lisp/emacs-lisp/cl-macs.el (cl-defstruct): Move predicate definition
        before field accessor definitions.

        Fix bad quoting of python-shell-interpreter

        `python-shell-calculate-command' was using `shell-quote-argument' as if
        it was generating a shell command, but its callers don't pass the result
        to a shell, and they expect to parse it with `split-string-and-unquote'.
        This caused problems depending on the flavor of shell quoting in
        effect (Bug#25025).

        * lisp/progmodes/python.el (python-shell-calculate-command): Use
        `combine-and-quote-strings' to quote the interpreter, so that it can be

        Make read1 more reentrant

        This is needed if ‘read’ is called soon after startup, before the
        Unicode tables have been set up, and it reads a \N escape and
        needs to look up a value the Unicode tables, a lookup that in turn
        calls read1 recursively.  Although this change doesn’t make ‘read’
        fully reentrant, it’s good enough to handle this case.
        * src/lread.c (read_buffer_size, read_buffer): Remove static vars.
        (grow_read_buffer): Revamp to use locals, not statics, and to
        record memory allocation un the specpdl.  All callers changed.
        (read1): Start with a stack-based buffer, and use the heap
        only if the stack buffer is too small.  Use unbind_to to
        free any heap buffer allocated.  Use bool for boolean.
        Redo symbol loop so that only one call to grow_read_buffer
        is needed.

         thread_state *' argument and use specpdl_ptr and specpdl of that
         thread.  Fixes crashes if find_symbol_value signals an error.
         src/thread.c (post_acquire_global_lock): Update current_thread

2013-08-31  Eli Zaretskii  <eliz@gnu.org>

        Improve MS-Windows implementation of threads.

         src/systhread.c (sys_cond_init): Set the 'initialized' member to
         true only if initialization is successful.  Initialize wait_count
         and wait_count_lock.
         (sys_cond_wait, sys_cond_signal, sys_cond_broadcast): If
         'initialized' is false, do nothing.
         (sys_cond_wait): Fix the implementation to avoid the "missed
         wakeup" bug: count the waiting threads, and reset the broadcast
         event once the last thread was released.
         (sys_cond_signal, sys_cond_broadcast): Use SetEvent instead of
         PulseEvent.  Don't signal the event if no threads are waiting.
         (sys_cond_destroy): Only close non-NULL handles.
         (sys_thread_create): Return zero if unsuccessful, 1 if successful.
         src/systhread.h (w32thread_cond_t): New member 'initialized'.

         wait_count_lock, respectively.

2013-07-03  Tom Tromey  <tromey@redhat.com>

2013-06-06  Tom Tromey  <tromey@redhat.com>

        fix a few latent issues in the thread patch

        * we called unbind_for_thread_switch unconditionally, but this
          is wrong if the previous thread exited
        * likewise, exiting a thread should clear current_thread
        * redundant assignment in run_thread
        * clean up init_threads - no need to re-init the primary thread

        This patch still sometimes causes weird hangs in "make check".
        However, I think that is a kernel bug, since Emacs enters the zombie
        state but its parent process hangs in wait.  This shouldn't happen.

        process changes

        This changes wait_reading_process_output to handle threads better.  It
        introduces a wrapper for select that releases the global lock, and it
        ensures that only a single thread can select a given file descriptor
        at a time.

        This also adds the thread-locking feature to processes.  By default a
        process can only have its output accepted by the thread that created
        it.  This can be changed using set-process-thread.  (If the thread
        exits, the process is again available for waiting by any thread.)

        Note that thread-signal will not currently interrupt a thread blocked
        on select.  I'll fix this later.

2012-08-15  Tom Tromey  <tromey@redhat.com>

        Prepare process.c for threads by not having global select masks.

2012-08-15  Tom Tromey  <tromey@redhat.com>

        This adds thread-blocker, a function to examine what a thread is
        blocked on.  I thought this would be another nice debugging addition.

        This adds names to mutexes.  This seemed like a nice debugging
        extension.

        This adds some tests of the threading code.

2012-08-15  Tom Tromey  <tromey@redhat.com>

        This supplies the mutex implementation for Emacs Lisp.

        A lisp mutex is implemented using a condition variable, so that we can
        interrupt a mutex-lock operation by calling thread-signal on the
        blocking thread.  I did things this way because pthread_mutex_lock
        can't readily be interrupted.

2012-08-15  Tom Tromey  <tromey@redhat.com>

        This adds most of the thread features visible to emacs lisp.

        I roughly followed the Bordeaux threads API:

        https://sionescu.github.io/bordeaux-threads/

        ... but not identically.  In particular I chose not to implement
        interrupt-thread or destroy-thread, but instead a thread-signaling
        approach.

        I'm still undecided about *default-special-bindings* (which I did not
        implement).  I think it would be more emacs-like to capture the let
        bindings at make-thread time, but IIRC Stefan didn't like this idea
        the first time around.

        There are one or two semantics issues pointed out in the patch where I
        could use some advice.

2012-08-15  Tom Tromey  <tromey@redhat.com>

        This turns thread_state into a pseudovector and updates various bits
        of Emacs to cope.

2012-08-15  Tom Tromey  <tromey@redhat.com>

        This introduces some new functions to handle the specpdl.  The basic
        idea is that when a thread loses the interpreter lock, it will unbind
        the bindings it has put in place.  Then when a thread acquires the
        lock, it will restore its bindings.

        This code reuses an existing empty slot in struct specbinding to store
        the current value when the thread is "swapped out".

        This approach performs worse than my previously planned approach.
        However, it was one I could implement with minimal time and
        brainpower.  I hope that perhaps someone else could improve the code
        once it is in.

2012-08-15  Tom Tromey  <tromey@redhat.com>

        This introduces the low-level system threading support.  It also adds
        the global lock.  The low-level support is a bit over-eager, in that
        even at the end of the present series, it will not all be used.  I
        think thiat is ok since I plan to use it all eventually -- in
        particular for the emacs lisp mutex implementation.

        I've only implemented the pthreads-based version.  I think it should
        be relatively clear how to port this to other systems, though.

        I'd also like to do a "no threads" port that will turn most things
        into no-ops, and have thread-creation fail.  I was thinking perhaps
        I'd make a future (provide 'threads) conditional on threads actually
        working.

        One other minor enhancement available here is to make it possible to
        set the name of the new thread at the OS layer.  That way gdb, e.g.,
        could display thread names.

2012-08-15  Tom Tromey  <tromey@redhat.com>

        This parameterizes the GC a bit to make it thread-ready.

        The basic idea is that whenever a thread "exits lisp" -- that is,
        releases the global lock in favor of another thread -- it must save
        its stack boundaries in the thread object.  This way the boundaries
        are always available for marking.  This is the purpose of
        flush_stack_call_func.

        I haven't tested this under all the possible GC configurations.
        There is a new FIXME in a spot that i didn't convert.

        Arguably all_threads should go in the previous patch.

2012-08-15  Tom Tromey  <tromey@redhat.com>

        This introduces a thread-state object and moves various C globals
        there.  It also introduces #defines for these globals to avoid a
        monster patch.

        The #defines mean that this patch also has to rename a few fields
        whose names clash with the defines.

        There is currently just a single "thread"; so this patch does not
        impact Emacs behavior in any significant way.

        Recognize more words from the Forth-2012 Standard.

        * lib-src/etags.c (Forth_words): Check for whitespace after defining
        words.  Create tag with make_tag instead of get_tag to avoid notiname
        which isn't appropriate for Forth.

        recomputation of 'tags-completion-table' next time it is used,
        since the list of tags table has changed.
        (visit-tags-table-buffer): Accept an additional optional argument

        Improve diff-mode navigation/manipulation

        This is Bug #17544.

        Navigation and use of diff buffers had several annoying corner cases
        that this patch fixes.  These corner cases were largely due to
        inconsistent treatment of file headers.  Say you have a diff such as
        this:

         --- aaa
         +++ bbb
         @@ -52,7 +52,7 @@
         hunk1
         @@ -74,7 +74,7 @@
         hunk2
         --- ccc
         +++ ddd
         @@ -608,6 +608,6 @@
         hunk3
         @@ -654,7 +654,7 @@
         hunk4

        The file headers here are the '---' and '+++' lines.  With the point on
        such a line, hunk operations would sometimes refer to the next hunk and
        sometimes to the previous hunk.  Most of the time it would be the
        previous hunk, which is not what the user would expect.  This patch
        consistently treats such headers as the next hunk.  So with this patch,
        if the point is on the '--- ccc' line, the point is seen as referring to
        hunk3.

        Specific behaviors this fixes are:

        1. It should be possible to place the point in the middle of a diff
        buffer, and press M-k repeatedly to kill hunks in the order they appear
        in the buffer.  With the point on hunk1, M-k M-k would kill hunk1 then
        hunk2.  With the point on hunk3, it would kill hunk3 then hunk4; this is
        fine.  However, with the point on hunk2, it'd kill hunk2 then hunk1.
        This is fixed by this patch.

        2. Similarly, it should be possible to apply hunks in order.  Previously
        with the point at the start, C-c C-a would apply the hunk1, then move
        the point to the first @@ header, and thus C-c C-a would try to apply
        the same hunk again.

        * lisp/vc/diff-mode.el (diff--wrap-navigation): New function to add better
        navigation logic to diff-{hunk,file}-{next,prev}.
        (diff-hunk-next, diff-hunk-prev):
        (diff-file-next, diff-file-prev): Better navigation logic if
        skip-hunk-start is true, which happens when called interactively.
        (diff-bounds-of-hunk, diff-find-source-location):
        (diff-apply-hunk, diff-current-defun, diff-refine-hunk): Small tweaks to
        improve hunk navigation.

        Upcase Path and ComSpec in process-environment

        Since 2016-07-18 "Keep w32 environment settings internal only", the
        upcasing of environment variables "Path" and "ComSpec" occurred after
        initializing process-environment.  This meant that Lisp code trying to
        override "PATH" environment had no effect (Bug #24956).

        * src/w32.c (init_environment): Upcase the "Path" and "ComSpec" entries
        in Vprocess_environment.

        Guard terminal parameter in XTerm mouse mode

        It has been observed (in the HTerm terminal emulator) that the
        event stored in the 'xterm-mouse-last-down' terminal parameter gets
        overwritten during a mouse drag operation, causing Emacs to attempt to
        synthesize the non-existing <drag-mouse-0> event.  Copy the event into
        the terminal parameter to protect against such modifications.

        * lisp/xt-mouse.el (xterm-mouse-translate-1): Guard against modification
        of input event list.

        Don't access pointers to freed storage in regex.c

        Remove __BOUNDED_POINTERS__ code, which does not work with

        add `vc-git-print-log-follow' and use it in `vc-git-print-log'

        When `vc-git-print-log-follow' is true and all files are

        Improve case-insensitive checks (Bug#24441)

        * doc/lispref/files.texi (Truenames): Simplify documentation,
        to avoid giving too much platform-specific information that
        may not be accurate anyway.
        * src/fileio.c (file_name_case_insensitive_p): Use pathconf with
        _PC_CASE_SENSITIVE if _PC_CASE_INSENSITIVE is not available.
        Otherwise if one approach fails (e.g., with errno == EINVAL), fall
        back on an alternative rather than returning false.  Try skipping
        the Darwin code, as it (1) no longer seems to be needed and (2)
        does not seem to match the Apple documentation.  Leave in two
        alternatives conditionally compiled based on
        DARWIN_OS_CASE_SENSITIVE_FIXME in case (1) or (2) is incorrect.

        Port --enable-gcc-warnings to Ubuntu 16.10

        * src/gmalloc.c: Include <stdlib.h>, so it declares

        * lisp/dired-aux.el (dired-do-create-files): Use

        (quickurl-list-populate-buffer): Use dolist instead.
        (quickurl-list-quit): Use quit-window.  It looks like this was written
        before the quit-window rewrite.  quit-window is very useful now.

        Problem reported by Ashish Shukla (Bug#24892).  I tested
        this on FreeBSD 11 x86-64 with HAVE_SBRK manually undefined.
        * configure.ac (system_malloc): Set to 'yes' if there is no sbrk.
        (sbrk): Check whether it exists.
        * src/alloc.c (my_heap_start) [!GNU_LINUX]:
        Do not define, since this function is now used only on GNU/Linux,
        and sbrk might not exist on other platforms.
        (malloc_initialize_hook) [!GNU_LINUX]:
        Do not call my_heap_start, since its side effect will never be used.

        Port emacsclient to FreeBSD 11 etc.

        * lib-src/emacsclient.c: Include <string.h>.  This is needed on
        platforms like FreeBSD 11 that use code involving strlen etc., and
        because <config.h> no longer includes string.h.

2016-11-07  Mark Oteiza  <mvoteiza@udel.edu>

        Prescribe history for read-regexp in query-replace

        In the fix for bug#24580, the history argument for read-regexp was
        removed erroneously; read-regexp's history argument defaults to
        regexp-history, not minibuffer-history.
        * lisp/replace.el (query-replace-read-from): Tell read-regexp to use
        minibuffer-history.  Fixes bug#24873.

        Stop force parameter of whitespace-report-region having global effect

        * lisp/whitespace.el (whitespace-report-region): Force parameter
        previously changed whitespace-style globally.  Fix this, and use
        whitespace-active-style, to take account of any changes the user may

        forces all classes of whitespace problem to be considered.
        (Bug#24745)

        If point is inside a comment or string, look for a list out of the
        comment/string.
        Escape '[' in doc string.
        * test/lisp/thingatpt-tests.el (thing-at-point-bug24627): Update

        Revert "Disable bracketed paste in a terminal in char mode"

        This change causes regressions, and besides, disabling BPM frame-wide
        for the sake of one buffer is the wrong solution.

        This reverts commit cf566b46a6cf85c6d54d0b0db80e32ed6ae8d1ca.

2016-11-02  Mark Oteiza  <mvoteiza@udel.edu>

        Disable bracketed paste in a terminal in char mode

        In char mode, a terminal doesn't accept bracketed paste events,
        therefore we should disable them; see Bug#24639.  To decouple the XTerm
        management from term.el, introduce a per-buffer setting to disable
        bracketed paste for that buffer.  If bracketed paste is inhiited for at
        least one buffer in a terminal, it is disabled for the whole terminal.

        * lisp/term/xterm.el (xterm-inhibit-bracketed-paste-mode): New mode to
        inhibit XTerm bracketed paste per buffer.
        (xterm--buffer-terminals, xterm--update-bracketed-paste)
        (xterm--bracketed-paste-possible, xterm--is-xterm): New helper
        functions.
        (xterm--init-bracketed-paste-mode): Remove unused helper
        function.
        (terminal-init-xterm): Update bracketed paste status when
        initializing an XTerm and on window configuration change.

        * lisp/term.el (term-char-mode, term-line-mode): Inhibit XTerm
        bracketed paste in char mode.

        Document and fix some bugs with side windows

        Add a documentation for side windows and fix some bugs
        found when testing their behavior.  Also add a new window
        parameter `no-delete-other-window', a new `display-buffer'
        alist member called `window-parameters', and functions to
        toggle and reverse side windows on a frame.  Add new function
        `window-swap-states' to exchange states of two live windows.

        * lisp/window.el (display-buffer-in-atom-window): Use
        `split-window-no-error'.

        `window--make-major-side-window', adjust
        caller, rewrite doc-string.  Make `window-side' and
        `window-slot' parameters persistent (Bug#23858).  Don't set
        `delete-window' parameter.  Add `preserve-size' entry to ALIST.

        (delete-other-windows): Handle ‘no-delete-other-window'
        parameter. Don't treat side windows separately (see discussion
        of Bug#24368) but keep optimization that makes the main window

        Restart blink cursor timers on interval changes

        This prevents surprising behavior when timer interval customizations are
        only applied whenever the timers happen to be restarted (see Bug#24372).

        * lisp/frame.el (blink-cursor--start-idle-timer)
        (blink-cursor--start-timer): New functions.
        (blink-cursor-start, blink-cursor-check, blink-cursor-mode): Use

        Use a simple keyword for a non-nil argument

        The second argument of `run-with-idle-timer' is Boolean, i.e. only nil
        and non-nil values are distinguished.  Passing a number here is
        confusing.  Pass a descriptive symbol instead.

        * lisp/frame.el (blink-cursor-mode, blink-cursor-check): Use

        Limit <config.h>’s includes

        This follows up on recent problems with the fact that config.h
        includes stdlib.h etc.; some files need to include stdlib.h later.
        config.h generally should limit itself to includes that are
        universally safe; outside of MS-Windows, only stdbool.h makes
        the cut among the files currently included.  So, move the
        other includes to just the files that need them (Bug#24506).
        * configure.ac (config_opsysfile): Remove, as this generic hook
        is no longer needed.
        * lib-src/etags.c, src/unexmacosx.c, src/w32.c, src/w32notify.c:
        * src/w32proc.c (_GNU_SOURCE):
        Remove, as it’s OK for config.h to do this now.
        * src/conf_post.h: Include <ms-w32.h>, instead of the generic
        config_opsysfile, for simplicity as this old way of configuring is
        now done only for the MS-Windows port.  Do not include <ms-w32.h>
        if DEFER_MS_W32_H, for the benefit of the few files that want its
        effects later.  Do not include <alloca.h>, <string.h>, or
        <stdlib.h>.  Other files modified to include these headers as
        needed, or to not include headers that are no longer needed.
        * src/lisp.h: Include <alloca.h> and <string.h> here, since
        some of the inline functions need them.
        * src/regex.c: Include <alloca.h> if not emacs.  (If emacs,
        we can rely on SAFE_ALLOCA.)  There is no longer any need to
        worry about HAVE_ALLOCA_H.
        * src/unexmacosx.c: Rely on config.h not including stdlib.h.
        * src/w32.c, src/w32notify.c, src/w32proc.c (DEFER_MS_W32_H):
        Define before including <config.h> first, and include <ms-w32.h>
        after the troublesome headers.

        The NetBSD library supports localtime_rz directly, and without

        (BITS_PER_LONG): Remove; all uses replaced by LONG_WIDTH.

        Correctly fontify C++ direct initializations with parens inside functions

        Or, more clearly, when something looks like a function declaration and it's
        inside a function, fontify it as a direct initialization.

        For this purpose, introduce a "brace stack" for each buffer, where an entry on
        the brace stack states how deeply nested a particular position is inside
        braces inside a "top level", which includes classes and namespaces.

        Also introduce a new "context", "top", with which c-font-lock-declarations
        signals to c-forward-decl-or-cast-1 that point is at the top level.

        * lisp/progmodes/cc-langs.el (c-get-state-before-change-functions): add
        c-truncate-bs-cache.
        (c-flat-decl-block-kwds, c-brace-stack-thing-key, c-brace-stack-no-semi-key)
        (c-type-decl-operator-prefix-key): new language constants/variables.

        * lisp/progmodes/cc-engine.el (c-bs-interval, c-bs-cache, c-bs-cache-limit)
        (c-bs-prev-pos, c-bs-prev-stack): New mostly local variables for the brace
        stack cache.
        (c-init-bs-cache, c-truncate-bs-cache, c-truncate-bs-cache, c-brace-stack-at)
        (c-bs-at-toplevel-p): New functions which manipulate the brace stack (cache).
        (c-find-decl-prefix-search): Keep track of whether we're at top level.
        (c-find-decl-spots): New local variable cfd-top-level which records what it
        says.  On calling cfd-fun, pass cfd-top-level as an additional argument.
        (c-forward-declarator): Add new element DECORATED to the result list.  Set it
        to non-nil when a match for c-type-decl-operator-prefix-key is found.
        (c-forward-decl-or-cast-1): Handle the newly introduced context "top".
        Introduce "CASE 9.5", which recognizes direct initializations.

        * lisp/progmodes/cc-fonts.el (c-font-lock-complex-decl-prepare)
        (c-font-lock-enum-tail, c-font-lock-cut-off-declarators)
        (c-font-lock-enclosing-decls, c-simple-decl-matchers, c-basic-matchers-after):
        Add appropriate `not-top' argument to calls to c-font-lock-declarators.
        (c-font-lock-declarators): Additional parameter `not-top'.  Use not-top to
        participate in the decision whether to fontify an identifier as a function or
        a variable.
        (c-font-lock-declarations): The internal lambda function takes an additional
        argument `toplev' from c-find-decl-spots, which it uses in determining the
        "context" of a declaration.  Add appropriate `not-top' argument to calls to
        c-font-lock-declarators.
        (c-font-lock-objc-methods): Add extra parameter to internal lambda function,
        like for c-font-lock-declarators.

        * lisp/progmodes/cc-mode.el (c-basic-common-init): Initialize the brace stack
        cache.

        Split regex character class test into smaller chunks

        Having one test for all character classes it is not always trivial to
        determine which class is failing.  This happens when failure is caused
        by ‘(should (equal (point) (point-max)))’ not being met.

        With per-character class tests, it is immediately obvious which test
        causes issues plus tests for all classes are run even if some of them
        fail.

        * test/src/regex-tests.el (regex-character-classes): Delete and split

        Remove dead loop iterations in regex.c

        RE_CHAR_TO_MULTIBYTE(c) yields c for ASCII characters and a byte8
        character for c ≥ 0x80.  Furthermore, CHAR_BYTE8_P(c) is true only
        for byte8 characters.  This means that

                c = RE_CHAR_TO_MULTIBYTE (ch);
                if (! CHAR_BYTE8_P (c) && re_iswctype (c, cc))

        is equivalent to:

                c = c;
                if (! false && re_iswctype (c, cc))

        for 0 ⪬ c < 0x80, and

                c = BYTE8_TO_CHAR (c);
                if (! true && re_iswctype (c, cc))

        for 0x80 ⪬ c < 0x100.  In other words, the loop never executes for
        c ≥ 0x80 and RE_CHAR_TO_MULTIBYTE call is unnecessary for c < 0x80.

        Port flexible array members to GCC + valgrind

        These changes are needed to conform to the C standard's rule for
        allocating structs containing flexible array members.  C11 says
        that malloc (offsetof (struct s, m) + n) does not suffice to
        allocate a struct with an n-byte tail; instead, malloc’s arg
        should be rounded up to the nearest multiple of alignof (struct s).
        Although this is arguably a defect in C11, gcc -O2 + valgrind
        sometimes complains when this rule is violated, and when debugging
        it’s better to keep valgrind happy.
        For details please see the thread containing the message at:

        Fix uses of (call-interactively) in lisp/emacs-lisp/checkdoc.el

        Passing the prefix argument as the 3rd argument to 'call-interactively'
        causes the prefix argument to be interpreted as events, which is not
        only wrong, but also causes a type error, as 'current-prefix-arg' can
        never be a vector as 'call-interactively' expects.  'call-interactively'
        automatically passes its prefix argument to the called function, so just
        do that, eliminating faulty behavior.

        is not a symbol, don't try to recognize it.  See
        https://lists.gnu.org/r/emacs-devel/2016-08/msg00502.html

        Memory allocator alignment fixes

        These changes remove some assumptions about heap allocator
        alignment that may not be true on unusual platforms.
        * src/alloc.c (POWER_OF_2): New macro.
        (ROUNDUP): Use it.
        (BLOCK_ALIGN): Verify that it is a power of 2.
        (aligned_alloc): Check that alignment passed to posix_memalign
        satisfies POSIX restrictions.
        (lisp_align_malloc): Check that size passed to aligned_alloc
        satisfies C11 restrictions.
        (MALLOC_IS_GC_ALIGNED): Check that GCALIGNMENT is 8, since the
        code has not been verified to work with other GCALIGNMENT values
        and the ice is thin here.  On GNU/Linux, malloc can return a value
        that is a multiple of 8 but not 16, even though __alignof__
        (max_align_t) is 16.  See:
        https://gcc.gnu.org/ml/gcc-patches/2016-08/msg01902.html
        (lmalloc) [USE_ALIGNED_ALLOC]: Use aligned_alloc only if size
        is a multiple of alignment, since C11 says the behavior is
        undefined otherwise.
        (lmalloc, lrealloc): Don't use INT_ADD_WRAPV on size_t, as in
        general this macro is restricted to signed types.  Remove
        assertion that the result is a multiple of GCALIGNMENT, as that
        need not be true.

        Pacify --enable-gcc-warnings for lib-src/pop.c

        * lib-src/pop.c: Include c-ctype.h.
        (socket_connection): Pacify --enable-gcc-warnings by rewriting to
        avoid 'if (v = E) ...'.  Use c_tolower, instead of a combination
        of the (undeclared) isupper and tolower.  Fix pointer constness
        problem.

        be correctly fontified.

        * lisp/progmodes/cc-engine.el (c-forward-type, c-forward-decl-or-cast-1):
        After reaching the "end" of a type expression, skip over any occurrences of
        c-type-decl-suffix-ws-ids-key.

        * lisp/progmodes/cc-langs.el (c-type-modifier-kwds): Remove "override" and
        "final" from the C++ value.
        (c-type-decl-suffix-ws-ids-kwds, c-type-decl-suffix-ws-ids-key): New lang
        constants/variables for "final" and "override".

        Fix an infinite loop in C++ Mode when we have "{ .... [ .... }"

        * lisp/progmodes/cc-fonts.el (c-font-lock-c++-lambda-captures): In the inner
        `while' form's condition, check for "\\s)" rather than merely "\\]", so that
        the loop won't hang at a "terminating" paren of a different type (due to the
        c-syntactic-re-search-forward at the end of the loop stopping at such
        characters).

        Adapt CC Mode for C++11 uniform initialization.

        For fontification, introduce a new "context", 'non-decl, to be used for
        brace
        lists; also a new value for the property 'c-type, called 'c-not-decl.

        * lisp/progmodes/cc-engine.el (c-back-over-compound-identifier): Check that
        an ostensible symbol we're going to move over isn't a keyword.
        (c-forward-decl-or-cast-1): CASE 1: Where we have two consecutive identifiers
        (hence a declaration), and an unmatched open paren, perform
        c-fdoc-shift-type-backwards to recognize the partial construct correctly.
        Whilst checking a type decl expression, check for and handle C++11's "copy
        initialization", where we have <type>(<constant>).  Recognize
        <id><id>(... (where the paren is unclosed) as a declaration.
        (c-looking-at-or-maybe-in-bracelist): New function, extracted from
        c-inside-bracelist-p.  Recognize as bracelists "{"s which are preceded by
        valid tokens other than "=".  Recognize a bracelist when preceded by a
        template declaration.
        (c-inside-bracelist-p): Call c-looking-at-or-maybe-in-bracelist in place of
        much inline code.
        (c-looking-at-inexpr-block): Amend so that it won't wrongly recognize an
        initialization starting "({" as an in-expression block, by checking for
        semicolons, as opposed to commas, separating elements inside it.
        (c-guess-continued-construct): (CASE B-2): Recognize a brace-list-open by
        calling c-looking-at-or-maybe-in-bracelist rather than checking for a
        preceding "=".  (CASE B-5): New code to recognize new construct "return {
        ...}".
        (c-guess-basic-syntax): (CASE 5A.3): Additionally recognize a "{" preceded by
        "return", or "{" preceded by <type><identifier> as a bracelist.

        * lisp/progmodes/cc-fonts.el (c-font-lock-declarations): Recognize brace
        lists, giving them `context' 'non-decl.  Pass over elements of one by regexp
        search for "," rather than calling c-forward-decl-or-cast-1.

        * lisp/progmodes/cc-langs.el (c-return-kwds, c-return-key): New lang
        constants/variables to recognize "return".
        (c-pre-id-bracelist-key): New lang constant/variable to recognize tokens
        which, when preceding an identifier followed by a brace, signify the brace as
        a bracelist.

        * lisp/progmodes/cc-mode.el (c-fl-decl-start): When searching outwards for
        the start of a "local" declaration, move out from an enclosing brace when
        that is the start of a brace list.

        Fix semantics of 'minibuffer' frame parameter

        The 'minibuffer' frame parameter is now t for a normal frame
        (a frame with a root window plus a minibuffer window) and the
        frame's minibuffer window for a minibuffer-less frame (a frame
        whose minibuffer window is on another frame).  See also:
        https://lists.gnu.org/r/emacs-devel/2016-07/msg01259.html

        * src/frame.c (make_frame, make_frame_without_minibuffer)
        (make_minibuffer_frame): When assigning the frame's minibuffer
        window also store corresponding 'minibuffer' frame parameter.
        (store_frame_param): Move the 'minibuffer' parameter checks to
        the beginning so we can silently override the value before it
        gets stored in the parameter alist.  Fix error handling.
        (Fframe_parameters): Return value of 'minibuffer' parameter
        unmodified.

        * lisp/frameset.el (frameset-filter-minibuffer): When the cdr of
        the parameter is a minibuffer window, save (minibuffer . nil)
        instead of (minibuffer . t).
        (frameset--reuse-frame): To find a non-minibuffer-only frame
        look out for a frame whose 'minibuffer' parameter is t instead
        of that frame's minibuffer window.
        (frameset-minibufferless-first-p): To find a minibuffer-less
        frame look out for a frame whose 'minibuffer' parameter is a
        window instead of nil.

        Check the limit both at macro expansion time (for a hard coded nil) and at run
        time in the generated code.  Tidy up these macros generally.

        * lisp/progmodes/cc-defs.el (c-safe-scan-lists): Check `limit' is present and
        not identically nil before generating a narrow-to-region call.  Generate code
        to check `limit' is not nil at run time.
        (c-go-list-forward, c-go-list-backward): Remove the generation of redundant
        narrow-to-region, instead calling c-safe-scan-lists directly.
        (c-go-up-list-forward, c-go-up-list-backward, c-go-down-list-forward)
        (c-go-down-list-backward): Invoke the corresponding macros without the "go-"
        to determine the destination position instead of generating a redundant
        narrow-to-region.

        * lisp/emacs-lisp/map.el (map--dispatch): Fix docstring

        The docstring referenced a non-existent parameter, as well as a
        parameter that has been renamed since the docstring was written. Fix
        both errors, fixing (Bug#24182).

        Amend hack-local-variables-prop-line not always to return any mode on line 1.

        This fixes bug #24266.

        * lisp/files.el (hack-local-variables-prop-line): Change the name of the
        parameter mode-only to handle-mode.  Change its meaning, such that it being
        set to a value non-nil and not t removes any mode parameter from the result
        list.  Leave its values nil and t with the same meanings they had.
        (hack-local-variables): Call hack-local-variables-prop-line appropriately.

        Fix minor bug in c-syntactic-re-search-forward.

        Bug was: when NOERROR is neither nil nor t, BOUND is non-nil, PAREN-LEVEL is
        non-nil, and the first internal search attempt fails, point wrongly ends up at
        BOUND, rather than just before the next closing paren.

        the above situation.

        quotes are substituted for, as this is no longer true.

2016-08-13  Paul Eggert  <eggert@cs.ucla.edu>

        Fix substitute-command-keys unibyte, alloc bugs

        * src/doc.c (Fsubstitute_command_keys): Fix some problems with
        unibyte strings and with buffer allocation.  Make strings
        multibyte, to avoid problems with unibyte strings that are not
        valid UTF-8 (Bug#24206).  Redo buffer allocation so that it is
        O(N), not O(N**2).  Avoid going past the end of the input string
        when given invalid input.  Avoid some unlikely problems in
        accessing the wrong storage after a GC.

        Fix process leak with make-network-process

        This problem was introduced by the recent async changes (Bug#23808).
        * src/process.c (Fmake_process): Move USE_SAFE_ALLOCA later,
        so that it follows the start_process_unwind unwind-protect.
        Set pid to -1 while the process is being created.
        (start_process_unwind): Omit unnecessary emacs_abort test.
        (connect_network_socket): Simplify use of counts.  Unwind
        bind_polling_period a bit earlier, so that a remove_process
        unwind-protect can be added when needed; this is the heart of
        the fix.  Undo the unwind-protect just before returning.

2016-08-11  Eli Zaretskii  <eliz@gnu.org>

        Avoid annoying re-scroll when buffer has many overlay strings

        * src/xdisp.c (redisplay_window): Add better recovery from a
        situation where window-start is on buffer position which has a
        before-string that includes newlines, with the result that point
        is not visible in the window, because the display engine starts
        displaying with the before-string.  (Bug#24179)

        Handle nil cell value in compiled printer functions.

        * doc/misc/ses.texi (Quick Tutorial): Minor clarification about the
        ses-range `!' modifier.
        (More on cell printing): Fix this that the fallback printer is
        `ses-prin1', not "%S".  That makes a difference for any cell value for
        which "%S" would insert a backslash characters.

        * lisp/ses.el (ses-local-printer-compile): Handle the nil cell value
        --- contrary to emacs-25 branches ses-call-printer does not handle
        prior to calling a function printer.  Not doing this would still work
        because the compiled function would throw and error and SES would in
        the end resort to the ses-prin1 fallback, however this way would not
        be in line with the raison d'être of compiling printer which is speed.

        'ses-range' modifier as an alternative to 'ses+'.
        (Advanced Features): Add a reference to node 'Nonrelocatable
        references' concerning function 'ses-rename-cell'.
        (Standard formula functions): Mention the '!' 'ses-range'
        modifier as an alternative to 'ses-delete-blanks'.
        (More on cell printing): Fix fallback printer
        definition.  Minor editorial formatting changes.
        (Nonrelocatable references): Document the use of
        'ses-rename-cell' as a better way to make cell reference
        non-relocatable.
        (The data area): Document the presence of local printer
        definitions in the data area.

        * lisp/ses.el (ses-delete-blanks): Do not remove
        *error*.  Any error in an argument should propagate into the
        using formula rather than being silently hidden !

        commit 8a38e948b039516e70176ebe20c5349e2ade6ac5
        Author: Vincent Belaïche <vincentb1@users.sourceforge.net>
        Date:   Thu Jul 28 19:49:37 2016 +0200

        Fix local printer set to left aligned string formatter.

        * lisp/ses.el (ses-local-printer-compile): Add missing case
        for left-aligned string formatter.

2016-08-09  Paul Eggert  <eggert@cs.ucla.edu>

        * .dir-locals.el (c-noise-macro-names): Remove NONVOLATILE.

2016-08-09  Stefan Monnier  <monnier@iro.umontreal.ca>

        * lisp/emacs-lisp/cconv.el: Fix λ-lifting in the presence of shadowing

        Change the code which detects and circumvents the case where one of the
        variables used in λ-lifting is shadowed, so that it also works when the
        shadowing comes before the λ-lifted function (bug#24171).

        (cconv--remap-llv): New function, extracted from cconv-convert.
        (cconv-convert): Use it, but differently for `let' and `let*'.

2016-08-09  Alan Mackenzie  <acm@muc.de>

        CC Mode: check for and fix missing call to before_change_functions.

        Fixes bug #24094 and bug #24074.

        This can happen with `revert-buffer' or sometimes `find-file', when the file
        is already in a buffer, but the file has been changed outside of Emacs.

        * lisp/progmodes/cc-mode.el (c-after-change): When we detect a missing
        invocation of c-before-change-functions, we assume the changed region is the
        entire buffer, and call c-before-change explicitly before proceding.

2016-08-09  Alan Mackenzie  <acm@muc.de>

        Make c-deprepertize-CPP work on deletion/insertion of "s.  Fixes bug #24132.

        * lisp/progmodes/cc-mode.el (c-depropertize-CPP): Rewrite function.

2016-08-09  Michael Albinus  <michael.albinus@gmx.de>

        Support $ENV in Tramp

        * doc/misc/tramp.texi (Remote processes): Explain setting $ENV.

        * etc/NEWS: Explain the "ENV" environment variable in
        `tramp-remote-process-environment'.

        * lisp/net/tramp-sh.el (tramp-remote-process-environment): Add "ENV=''".
        (tramp-open-shell): Read $ENV value from
        `tramp-remote-process-environment'.
        (tramp-open-connection-setup-interactive-shell): Set values in
        proper order.

2016-08-09  Paul Eggert  <eggert@cs.ucla.edu>

        Simplify exec_byte_code via moving decls etc.

        * src/bytecode.c (exec_byte_code): Simplify, mostly by moving
        initializers into decls, and by omitting some unnecessary
        changes to ‘top’.  This improves performance a bit on x86-64,
        as it happens.

2016-08-09  Paul Eggert  <eggert@cs.ucla.edu>

        Remove interpreter’s byte stack

        This improves performance overall on my benchmark on x86-64,
        since the interpreted program-counter resides in a machine
        register rather than in RAM.
        * etc/DEBUG, src/.gdbinit: Remove xbytecode GDB command, as there
        is no longer a byte stack to decode.
        * src/bytecode.c (struct byte_stack, byte_stack_list)
        (relocate_byte_stack): Remove.  All uses removed.
        (FETCH): Simplify now that pc is now local (typically, in a
        register) and no longer needs to be relocated.
        (CHECK_RANGE): Remove.  All uses now done inline, in a different way.
        (BYTE_CODE_QUIT): Remove; now done by op_relative_branch.
        (exec_byte_code): Allocate a copy of the function’s bytecode,
        so that there is no problem if GC moves it.
        * src/lisp.h (struct handler): Remove byte_stack member.
        All uses removed.
        (SAFE_ALLOCA_LISP_EXTRA): New macro, a generalization of
        SAFE_ALLOCA_LISP.
        (SAFE_ALLOCA_LISP): Use it.

2016-08-09  Paul Eggert  <eggert@cs.ucla.edu>

        Remove arbitrary limit on bytecode maxdepth

        * src/bytecode.c (exec_byte_code): Remove MAX_ALLOCA-based limit
        on bytecode maxdepth, by using SAFE_ALLOCA_LISP instead of alloca.

2016-08-09  Paul Eggert  <eggert@cs.ucla.edu>

        Tune bytecode quitting

        * src/bytecode.c (BYTE_CODE_QUIT): Check for GC, too.  Do the
        check only once every 256 times.  This should be good enough, and
        improves performance significantly on x86-64 as branch-prediction
        typically assumes checking will not be done so the instruction
        pipeline stays fuller.
        (exec_byte_code): Set up the quit counter.  Don’t call maybe_gc
        directly, as BYTE_CODE_QUIT does that now.

2016-08-09  Paul Eggert  <eggert@cs.ucla.edu>

        Simplify BYTE_CODE_SAFE checking

        * src/bytecode.c (BYTE_CODE_SAFE): Default to false, so that it
        can be used outside #if.  All uses of ‘defined BYTE_CODE_SAFE’
        changed to ‘BYTE_CODE_SAFE’.  Use BYTE_CODE_SAFE in plain
        expressions instead of #if expressions when this is easy.
        (struct byte_stack) [BYTE_CODE_SAFE]: Remove member ‘bottom’,
        as it is no longer needed.
        (exec_byte_code): Omit #if BYTE_CODE_SAFE when this is easy.
        Simplify stack-overflow checking when BYTE_CODE_SAFE.

2016-08-09  Paul Eggert  <eggert@cs.ucla.edu>

        Get BYTE_CODE_METER working again

        BYTE_CODE_METER hasn’t worked since 2013, and nobody seems to have
        noticed.  Perhaps we should remove it?
        * src/bytecode.c (METER_2) [BYTE_CODE_METER]:
        Use *aref_addr instead of AREF, since it needs to be an lvalue.

2016-08-08  Eli Zaretskii  <eliz@gnu.org>

        Fix cursor position under scroll-conservatively and overlay strings

        * src/xdisp.c (try_scrolling): Handle the case where the last
        visible screen line of a window displays a before- or after-string
        that takes up the whole screen line, and therefore there's no
        place to display the cursor, even though the window does seem to
        include the position of point.  (Bug#24179)

2016-08-08  Michael Albinus  <michael.albinus@gmx.de>

        * lisp/files.el (file-ownership-preserved-p): Fix docstring.  (Bug#23998)

2016-08-07  Paul Eggert  <eggert@cs.ucla.edu>

        Tune interpretation of integer arglist descriptor

        * src/bytecode.c (exec_byte_code):
        Simplify and tune when INTEGERP (args_template).

2016-08-07  Noam Postavsky  <npostavs@gmail.com>

        Fix debugging of string-match-p errors

        * src/eval.c (call_debugger): Bind inhibit-changing-match-data to nil so
        that debugger code that needs to do regexp match won't break
        (Bug #23949, Bug #24166, Bug#16294).

2016-08-07  Michael Albinus  <michael.albinus@gmx.de>

2016-08-06  Noam Postavsky  <npostavs@gmail.com>

        Make sh-mode always use p-s-lookup-properties

        This lets functions which rely on syntax-propertize for parsing
        work correctly even before font lock has a chance to run.

        parse-sexp-lookup-properties unconditionally (Bug #4920).

        * lisp/indent.el (indent-rigidly): Pass `deactivate-mark' as the ON-EXIT

        Fix accessing regex-resources in out-of-tree test runs in regex-tests

        [82a487d: Fix reading of regex-resources in regex-tests] attempted to
        fix regex-tests failing when run from the source tree (i.e. via make)
        by hard-coding path to regex-resources directory relative to the test
        directory.

        This fixed runs from the tree but broke the test when run using other
        methods.

        Fix by trying ‘load-file-name’ or ‘buffer-file-name’, whichever is set.

        * test/src/regex-tests.el (regex-tests--resources-dir): New variable
        storing path to the regex-resources directory.
        (regex-tests-generic-line): Use aforementioned variable.

        Hardcode regex syntax to remove dead code handling different syntax

        Emacs only ever uses its own regex syntax so support for other syntaxes
        is never used.  Hardcode the syntax so that the compilar can detect such
        dead code and remove it from compiled code.

        The only exception is RE_NO_POSIX_BACKTRACKING which can be separatelly
        specified.  Handle this separatelly with a function argument (replacing
        now unnecessary syntax argument).

        With this patchset, size of Emacs binary on x86_64 machine is reduced by
        around 60 kB:

                new-sizes:-rwx------ 3 mpn eng 30254720 Jul 27 23:31 src/emacs
                old-sizes:-rwx------ 3 mpn eng 30314828 Jul 27 23:29 src/emacs

        * src/regex.h (re_pattern_buffer): Don’t define syntax field #ifdef emacs.
        (re_compile_pattern): Replace syntax with posix_backtracking argument.

        * src/regex.c (print_compiled_pattern): Don’t print syntax #ifdef emacs.
        (regex_compile): #ifdef emacs, replace syntax argument with
        posix_backtracking which is now used instead of testing for
        RE_NO_POSIX_BACKTRACKING syntax.
        (re_match_2_internal): Don’t access bufp->syntax #ifndef emacs.
        (re_compile_pattern): Replace syntax with posix_backtracking argument.

        * src/search.c (compile_pattern_1): Pass boolean posix_backtracking
        instead of syntax to re_compile_pattern.

        * src/regex.c (re_set_whitespace_regexp, whitespace_regexp): Delete.
        (regex_compile): Add whitespace_regexp argument #ifdef emacs and wrap
        whitespace_regexp-related code in an #ifdef emacs so it’s compiled out
        unless building Emacs.
        (re_compile_pattern): Pass whitespace_regexp argument to regex_compile

        * src/search.c (compile_pattern_1): Don’t use re_set_whitespace_regexp,
        pass the regex as argument to re_compile_pattern instead.

2016-08-02  Michal Nazarewicz  <mina86@mina86.com>

        Get rid of re_set_syntax

        Instead of using a global variable for storing regex syntax, pass it
        to re_compile_pattern.  This is only enabled when compiling Emacs (i.e.
        ‘#ifdef emacs’).

        * src/regex.h (re_set_syntax): Declare only #ifndef emacs.
        (re_compile_pattern): Now takes syntax argument #ifdef emacs.

        * src/regex.c (re_syntax_options): Define only #ifndef emacs.
        (re_compile_pattern): Use the new syntax argument #ifdef emacs.

        * src/search.c (compile_pattern_1): Don’t use re_set_syntax and
        instead pass syntax to re_compile_pattern directly.

        Remove dead opcodes in regex bytecode

        There is no way to specify before_dot and after_dot opcodes in a regex
        so code handling those ends up being dead.  Remove it.

        * src/regex.c (print_partial_compiled_pattern, regex_compile,
        analyze_first, re_match_2_internal): Remove handling and references to
        before_dot and after_dot opcodes.

2016-08-02  Michal Nazarewicz  <mina86@mina86.com>

        Refactor regex character class parsing in [:name:]

        re_wctype function is used in three separate places and in all of
        those places almost exact code extracting the name from [:name:]
        surrounds it.  Furthermore, re_wctype requires a NUL-terminated
        string, so the name of the character class is copied to a temporary
        buffer.

        The code duplication and unnecessary memory copying can be avoided by
        pushing the responsibility of parsing the whole [:name:] sequence to
        the function.

        Furthermore, since now the function has access to the length of the
        character class name (since it’s doing the parsing), it can take
        advantage of that information in skipping some string comparisons and
        using a constant-length memcmp instead of strcmp which needs to take
        care of NUL bytes.

        * src/regex.c (re_wctype): Delete function.  Replace it with:
        (re_wctype_parse): New function which parses a whole [:name:] string
        and returns a RECC_* constant or -1 if the string is not of [:name:]
        format.
        (regex_compile): Use re_wctype_parse.
        * src/syntax.c (skip_chars): Use re_wctype_parse.

        (regex-tests-BOOST, regex-tests-PCRE, regex-tests-PTESTS-whitelist,

        Fix ‘[[:cc:]]*literal’ regex failing to match ‘literal’ (bug#24020)

        The regex engine tries to optimize Kleene star by avoiding backtracking
        when it can detect that star’s operand cannot match what follows it in
        the pattern.

        For example, when ‘[[:alpha:]]*1’ tries to match a ‘foo’, the engine
        will test the longest match for ‘[[:alpha:]]*’, namely ’foo’ which is
        the entire string.  Literal digit one still present in the pattern will
        however not match the remaining empty string.

        Normally, backtracking would be performed trying a shorter match for the
        character class (namely ‘fo’ leaving ‘o’ in the string), but since the
        engine knows whatever would be put back into the string cannot possibly
        match literal digit one so no backtracking will be attempted.

        In the regexes of the form ‘[[:CC:]]*X’, the optimization can be applied
        if the character class CC does not match character X.  In the above
        example, this holds because digit one is not in alpha character class.

        This test is performed by mutually_exclusive_p function but it did not
        check class bits of a charset opcode.  This resulted in an assumption
        that character classes do not match multibyte characters.  For example,
        it would incorrectly conclude that [[:alpha:]] doesn’t match ‘ż’.

        This, in turn, led to the aforementioned Kleene star optimization being
        incorrectly applied in patterns such as ‘[[:graph:]]*☠’ (which should
        match ‘☠’ but doesn’t as can be tested by executing
            (string-match-p "[[:graph:]]*☠" "☠")
        which should return 0 but instead yields nil.

        This issue affects any class witch matches multibyte characters, i.e.
        if ‘[[:cc:]]’ matches a multibyte character X then ‘[[:cc:]]*X’ will
        fail to match ‘X’.

        * src/regex.c (executing_charset): A new function for executing the
        charset and charset_not opcodes.  It performs check on the character
        taking into consideration existing bitmap, range table and class bits.
        It also advances the pointer in the regex bytecode past the parsed
        opcode.
        (CHARSET_LOOKUP_RANGE_TABLE_RAW, CHARSET_LOOKUP_RANGE_TABLE): Removed.
        Code now included in executing_charset.
        (mutually_exclusive_p, re_match_2_internal): Changed to take advantage
        of executing_charset function.

        * test/src/regex-tests.el: New file with tests for the character class
        matching.

        ‘signal’ no longer returns

        Although for decades ‘signal’ has been documented to not return,
        a corner case in the Lisp debugger causes ‘signal’ to return.
        Remove the corner case and adjust Emacs internals accordingly.
        An alternative would be to document the corner case, but this
        would complicate the Lisp API unnecessarily.  (Bug#24047)

        Qnil) changed to use this new function instead.
        (Fsignal): Use signal_or_quit.  Now _Noreturn.  All callers
        changed.
        (xsignal): Move to lisp.h.
        * src/lisp.h (xsignal): Now an inline function, as it's now

        Keep w32 environment settings internal only

        * src/emacs.c (main) [WINDOWSNT]: Move init_environment calls after the

        Port to glibc 2.24 (pre-release) + ppc64

        Inspired by a suggestion by Florian Weimer in:
        https://sourceware.org/ml/libc-alpha/2016-07/msg00425.html
        * configure.ac (HAVE_PERSONALITY_ADDR_NO_RANDOMIZE):
        Rename from HAVE_PERSONALITY_LINUX32, and check for
        ADDR_NO_RANDOMIZE (the crucial thing) instead of for LINUX32.
        All uses changed.
        * src/emacs.c (main) [HAVE_PERSONALITY_ADDR_NO_RANDOMIZE]:
        Use ADDR_NO_RANDOMIZE from personality.h rather than inventing the
        flag ourselves.  Just set that flag, rather than also setting the
        persona.  When doing it, avoid functions like putenv that may
        allocate memory.

        * src/xwidget.c: Remove #include directives that are not needed.
        Also, don’t conditionalize #includes on HAVE_X_WINDOWS, since this
        file is compiled only if the X interface is available.

        Revert "Cleanup tooltips"

        This reverts commit 20038f8ab75dd1551412a43cd58520c483c22921.

        I am reverting this change because it was applied without prior discussion
        on emacs-devel, and has been found to break the NS port.  It needs more
        testing and review before it should be applied here.

        * src/w32fns.c (setup_w32_kbdhook): Don't install the keyboard
        hook if we are being debugged.  This avoids hosing the debugger,
        because the hook is global, and is called in the context of the
        thread which installed it, and that thread is stopped when GDB has
        control.  Reported by Fabrice Popineau <fabrice.popineau@gmail.com>.

        Amend CC Mode to handle big C++ raw strings correctly.

        Problems were caused by such a string spanning jit-lock chunks, and by a flaw

        macro boundaries here.

        point already being within a raw string.

        with other Emacsen.

        Don’t create unnecessary marker in ‘delete-trailing-whitespace’

        * lisp/simple.el (delete-trailing-whitespace): If END argument is nil,
        there is no need for the end-marker to be created.

2016-07-04  Michal Nazarewicz  <mina86@mina86.com>

        Simplify ‘delete-trailing-whitespace’ by not treating \n as whitespace

        * lisp/simple.el (delete-trailing-whitespace): Set newline’s character
        syntax to non-whitespace so that ‘\s-’ regular expression does not match
        it.

        This simplifies the loop slightly since a simple ‘\s-+$’ can be used and
        as a consequence ‘line-beginning-position’ function does not need to be
        called any longer.

        Furthermore, when newline has whitespace syntax, ‘\s-$’ regular
        expression ends up matching empty lins since ‘\s-’ matches newline
        characetr of proceeding line.  This leads to needless loop iterations.

        Since previous change to ‘delete-trailing-whitespace’ already introduced
        ‘with-syntax-table’, take advantage of it and also overwrite newline’s
        character syntax.

2016-07-04  Michal Nazarewicz  <mina86@mina86.com>

        Make ‘delete-trailing-whitespace’ delete spaces after form feed

        * lisp/simple.el (delete-trailing-whitespace): Treat form fead as
        a non-whitespace character (regradless of whether it’s character syntax
        is whitespace) and delete any whitespace following it instead of leaving
        lines with form feeds completely unchanged.  I.e. a line like "\f " will
        now became "\f".

        FACE_FROM_ID_OR_NULL, as the resulting face is immediately
        dereferenced.
        (fill_gstring_glyph_string): Call FACE_FROM_ID, not
        FACE_FROM_ID_OR_NULL, as the resulting face will be dereferenced
        when the glyph string is drawn.
        (BUILD_COMPOSITE_GLYPH_STRING): Call FACE_FROM_ID, not
        FACE_FROM_ID_OR_NULL, as the resulting face will be dereferenced
        in fill_composite_glyph_string.
        (calc_line_height_property): Call FACE_FROM_ID_OR_NULL rather that
        FACE_FROM_ID, since the function and its caller can cope with that
        situation.  Conflate 3 tests of missing face or font into just
        one.
        * src/xfaces.c (Fx_list_fonts, Fface_font, lookup_face): Call
        FACE_FROM_ID_OR_NULL rather that FACE_FROM_ID, since these
        functions can cope with that situation.
        (lookup_derived_face): Don't call FACE_FROM_ID if the result will
        not be used.
        * src/w32console.c (w32_face_attributes): Remove redundant 'eassert'.

2016-06-23  Eli Zaretskii  <eliz@gnu.org>

        * lisp/international/characters.el (standard-case-table): Improve last change.

2016-06-23  Eli Zaretskii  <eliz@gnu.org>

        Improve results of 'upcase' for characters with title-case

        * lisp/international/characters.el (standard-case-table): Swap the
        order of some lines, to have 'upcase' return the upper-case
        variant, not the title-case, for some characters whose lower-case
        map to the same codepoints.  (Bug#23833)

2016-06-23  Alan Mackenzie  <acm@muc.de>

        Make typing into incomplete C++ raw strings work, and make it work fast enough

        * lisp/progmodes/cc-engine.el (c-beginning-of-macro, c-state-pp-to-literal):
        Put `save-match-data' around calls to `looking-at' to enable the use of the
        match data in higher level functions.

        * lisp/progmodes/cc-fonts.el (c-font-lock-declarations)
        (c-font-lock-cut-off-declarators): Use `limit' rather than `(point-max)' as a
        limit to speed up handling of C++ raw strings.

2016-06-23  Eli Zaretskii  <eliz@gnu.org>

        Fix handling of LWINDOW key on MS-Windows

        * src/w32fns.c (funhook): Correct a typo which broke handling of
        the LWINDOW key.  (Bug#23830)

2016-06-22  Eli Zaretskii  <eliz@gnu.org>

        * admin/unidata/copyright.html:
        * admin/unidata/BidiBrackets.txt:
        * admin/unidata/UnicodeData.txt: Update from Unicode 9.0.0, just
        released.

2016-06-22  Eli Zaretskii  <eliz@gnu.org>

        Fix test for whether the '.el' file is newer than '.elc'

        * src/lread.c (Fload): Don't overwrite the last character of the
        file name in FOUND with 'c', unless the file name ended in ".elc"
        to begin with.  Don't treat empty files as byte-compiled.  See
        https://lists.gnu.org/r/emacs-devel/2016-06/msg00463.html
        for more details of the problem this caused.

2016-06-22  Eli Zaretskii  <eliz@gnu.org>

        Fix 'insert-file-contents' when REPLACE is non-nil

        * src/fileio.c (maybe_move_gap): New function to move the gap to
        the end of a buffer, if it isn't there already.
        (Finsert_file_contents): Call 'maybe_move_gap' before using
        conversion_buffer's text as a C 'char' array.  (Bug#23659)
        * src/coding.c (decode_eol): Compute the byte increment before
        calling del_range_2, because the latter can invalidate the pointer
        to buffer text.

2016-06-22  Ken Brown  <kbrown@cornell.edu>

        Avoid compiler warning

        * src/w32fns.c (Fx_show_tip): Don’t jump over auto initialization.

2016-06-22  Stefan Monnier  <monnier@iro.umontreal.ca>

        * lisp/emacs-lisp/syntax.el (syntax-propertize): Flush extended region.

2016-06-22  Ken Brown  <kbrown@cornell.edu>

        Fix last change to FRAME_INTERNAL_BORDER_WIDTH

        * src/w32fns.c (x_set_internal_border_width): Don’t use
        FRAME_INTERNAL_BORDER_WIDTH(), which is now a function call, as an
        lvalue.

2016-06-21  Paul Eggert  <eggert@cs.ucla.edu>

        Improve --without-x GCC pacification

        * src/composite.c (autocmp_chars):
        * src/conf_post.h (DebPrint) [HAVE_NTGUI && !DebPrint && !EMACSDEBUG]:
        Use simpler ((void) 0) for no-op expression returning void.
        * src/dispextern.h [HAVE_WINDOW_SYSTEM]:
        Include fontset.h, for face_for_char.
        (FACE_SUITABLE_FOR_ASCII_CHAR_P, FACE_FOR_CHAR):
        Now inline functions instead of macros.  This avoids the need for
        all those casts to void.
        (FACE_SUITABLE_FOR_ASCII_CHAR_P): Omit 2nd (unused) arg.
        All uses changed.
        * src/frame.c (Ficonify_frame, Fset_frame_position):
        * src/xdisp.c (Fmove_point_visually, show_mouse_face):
        * src/xdisp.c (note_mode_line_or_margin_highlight)
        (note_mouse_highlight):
        Assume HAVE_WINDOW_SYSTEM for simplicity, since the code should
        now work either way without generating warnings.
        * src/frame.c (display_available) [HAVE_WINDOW_SYSTEM]: New function.
        (window_system_available) [HAVE_WINDOW_SYSTEM]: Move to frame.h.
        (decode_window_system_frame): Use check_window_system instead of
        rolling the code ourself.  Return needed only if HAVE_WINDOW_SYSTEM.
        (decode_window_system_frame, check_window_system):
        Merge the HAVE_WINDOW_SYSTEM and !HAVE_WINDOW_SYSTEM versions into one.
        * src/frame.c (Ficonify_frame, Fset_frame_position):
        * src/xdisp.c (show_mouse_face, define_frame_cursor1)
        (note_mouse_highlight):
        Narrow the scope of the HAVE_WINDOW_SYSTEM #ifdef;
        this is a better way to pacify GCC.
        * src/xdisp.c (x_set_left_fringe, x_set_right_fringe)
        (x_set_right_divider_width, x_set_bottom_divider_width):
        * src/xfns.c (x_set_internal_border_width):
        Don’t use what are now function calls as lvalues.
        * src/frame.h (WINDOW_SYSTEM_RETURN): New macro.
        (decode_window_system_frame, check_window_system):
        Use it, to avoid the need for duplicate declarations.
        (window_system_available): Now an inline function.
        (display_available): New decl.
        (frame_dimension): New inline function.
        (FRAME_FRINGE_COLS, FRAME_LEFT_FRINGE_WIDTH)
        (FRAME_RIGHT_FRINGE_WIDTH, FRAME_TOTAL_FRINGE_WIDTH)
        (FRAME_INTERNAL_BORDER_WIDTH, FRAME_RIGHT_DIVIDER_WIDTH)
        (FRAME_BOTTOM_DIVIDER_WIDTH):
        Use it, to avoid the need for duplicate definitions.
        Now inline functions instead of macros.
        * src/gnutls.c (gnutls_log_function2i): Remove.
        * src/gnutls.h (GNUTLS_LOG2i): Use ‘message’ directly.
        This avoids complaints about gnutls_log_function2i being defined
        and not used on older platforms that do not need to call GNUTLS_LOG2i.
        * src/image.c (DefaultDepthOfScreen) [0]: Remove unused macro.
        * src/lisp.h (AUTO_STRING_WITH_LEN): Revert change from ‘type id =
        expr’ to ‘type id; id = expr’, as this would suppress valid
        jump-misses-init diagnostics.  Let’s find a better way to address
        the problem.
        * src/vm-limit.c (__MALLOC_HOOK_VOLATILE):
        Define only if needed.
        * src/xdisp.c (handle_single_display_spec):
        Simplify fringe_bitmap computation.
        (define_frame_cursor1): Do nothing unless in a window system.
        All callers changed and simplified.
        * src/xfaces.c (realize_default_face):
        Use a simpler way to pacify GCC when a return value is not used
        on some platforms.

2016-06-21  Phillip Lord  <phillip.lord@russet.org.uk>

        Ensure undo-boundary after all commands

        * lisp/simple.el (undo-auto--boundaries): Ensure an undo-boundary after
          every command whether it (apparently) changes the buffer or not.

        See Bug#23785 for discussion.

2016-06-21  Eli Zaretskii  <eliz@gnu.org>

        Fix vertical layout calculations when newline has line-height property

        * src/xdisp.c (move_it_in_display_line_to): Reset the iterator's
        'constrain_row_ascent_descent_p' flag after processing the
        newline, similar to what 'display_line' does.  Without this, the
        flag remains set once set by x_produce_glyphs, and causes the
        vertical layout calculations to go awry, because Emacs thinks the
        screen lines have zero height.  (Bug#23850)

2016-06-20  Ken Brown  <kbrown@cornell.edu>

        Fix compiler warnings in Cygwin-w32 build

        * src/conf_post.h (DebPrint) [!EMACSDEBUG]: Add empty do-while
        loop to avoid compiler warnings about empty body of 'if'
        statement.

        * src/image.c [HAVE_NTGUI] (DefaultDepthOfScreen): Disable unused
        macro.
        (x_create_bitmap_from_data): Declare 'frame'.
        (x_create_bitmap_from_file): Don't declare unused variable

        * src/lisp.h (AUTO_STRING_WITH_LEN): Avoid initialization to
        prevent "jump-misses-init" compiler warnings.

        * src/w32fns.c (check_w32_winkey_state): Define and use only if
        WINDOWSNT.
        (Fx_show_tip): Declare 'f'.
        (Fx_file_dialog): Declare 'filter_a' only if not NTGUI_UNICODE.
        (w32_strerror): Use format specifier %d for sprintf argument of
        type int.
        (emacs_abort): Cast sprintf argument of type DWORD to unsigned
        int, and use format specifier %x, for compatibility with Cygwin.
        (unicode_append_menu) [NTGUI_UNICODE]:
        * src/w32menu.c [NTGUI_UNICODE] (get_menu_item_info)
        (set_menu_item_info, unicode_append_menu)
        (unicode_message_box):
        * src/menu.c [NTGUI_UNICODE] (unicode_append_menu): Define as
        functions rather than macros to avoid "address will always
        evaluate as true" compiler warnings.

        * src/w32font.c (w32_to_x_charset): Use format specifier %d for
        sprintf argument of type int.

        * src/w32term.c (x_draw_glyphless_glyph_string_foreground): Cast
        sprintf argument of type int to unsigned int to match %X format
        specifier.
        (w32_scroll_bar_handle_click):
        (w32_horizontal_scroll_bar_handle_click): Declare 'f'.

        * src/w32term.h (FRAME_DISPLAY_INFO): Explicitly discard unused
        argument.

2016-06-20  Ken Brown  <kbrown@cornell.edu>

        Fix compiler warnings in no-window-system-build

        * src/composite.c (autocmp_chars): Declare and set 'f' only if
        HAVE_WINDOW_SYSTEM.

        * src/dispextern.h (FACE_SUITABLE_FOR_ASCII_CHAR_P)
        (FACE_FOR_CHAR): Explicitly discard unused arguments.

        * src/font.c (font_open_entity): Declare 'min_width' where it is
        first set, and only if HAVE_WINDOW_SYSTEM.

        * src/frame.c [!HAVE_WINDOW_SYSTEM] (decode_window_system_frame):
        Define _Noreturn version to avoid "suggest attribute noreturn"
        compiler warning.
        (check_window_system): Declare as _Noreturn.
        (Ficonify_frame):
        (Fset_frame_position): Don’t declare and set 'f'.

        * src/frame.h [!HAVE_WINDOW_SYSTEM] (decode_window_system_frame)
        (check_window_system):  Add _Noreturn prototypes.
        (FRAME_FRINGE_COLS, FRAME_TOTAL_FRINGE_WIDTH)
        (FRAME_LEFT_FRINGE_WIDTH, FRAME_RIGHT_FRINGE_WIDTH)
        (FRAME_INTERNAL_BORDER_WIDTH, FRAME_RIGHT_DIVIDER_WIDTH)
        (FRAME_BOTTOM_DIVIDER_WIDTH): Explicitly discard unused argument.

        * src/xdisp.c (handle_single_display_spec): Declare
        'fringe_bitmap' only if HAVE_WINDOW_SYSTEM.
        (append_space_for_newline): Declare 'g' where it is first set.
        (Fmove_point_visually): Declare and set 'target_is_eol_p' only if
        HAVE_WINDOW_SYSTEM.
        (show_mouse_face): Declare and set 'f' and 'phys_cursor_on_p' only
        if HAVE_WINDOW_SYSTEM.

        (file-notify-test07-backup)
        (file-notify-test08-watched-file-in-watched-dir): Make test

        Minor ABLOCKS_BUSY cleanups in alloc.c

        * src/alloc.c (ABLOCKS_BUSY): Rename arg to avoid potential clash
        with member ‘abase’ in definiens.
        (lisp_align_malloc, lisp_align_free): Use bool for boolean.
        Avoid compiler warning with fewer casts.
        (lisp_align_free): Check busy-field values; this can help the
        compiler a bit when optimizing, too.

2016-06-19  Dmitry Gutov  <dgutov@yandex.ru>

        by catching them earlier.

        Use string-to-unibyte (bug#23750).

2016-06-19  Eli Zaretskii  <eliz@gnu.org>

        (c-directly-in-class-called-p): New function.

        map.el (map-merge*): Use `map-into' at beginning rather than end

        * lisp/emacs-lisp/map.el (map-merge): Use `map-into' for the first map,
        and don't use of an intermediate alist.
        (map-merge-with): Same, plus use `cl-callf' to try and avoid performing
        3 lookups per inner iteration.

        * lisp/generic-x.el (ansible-inventory-generic-mode): Add new mode.

2016-06-14  Paul Eggert  <eggert@cs.ucla.edu>

        Fix ifdef-vs-if typo with RANDR13_LIBRARY

        * src/xfns.c (x_get_monitor_attributes_xrandr): Use #if, not #ifdef.
        This ports to systems that predate xrandr 1.3. See Christian Lynbech in:
        https://lists.gnu.org/r/emacs-devel/2016-06/msg00198.html

2016-06-14  Paul Eggert  <eggert@cs.ucla.edu>

        Port to platforms where char * has top bit set

        This fixes a five-year-old FIXME comment.  Although I don’t know
        of a platform where this is a problem in practice, better safe
        than sorry.
        * src/doc.c (Fdocumentation): If SUBRP, simply use doc as integer,
        as it is now an integer, not char *.
        (store_function_docstring): Offset is now EMACS_INT, not ptrdiff_t;
        this is a file offset and EMACS_INT is better if --with-wide-int.
        If SUBRP, simply store the offset rather than negating it and
        converting it to char *.
        * src/lisp.h (struct Lisp_Subr.doc): Now EMACS_INT, not char *.

2016-06-14  Paul Eggert  <eggert@cs.ucla.edu>

        Remove recursion from store_function_docstring

2016-06-14  Ken Brown  <kbrown@cornell.edu>

        Remove system-specific -I switch from Cygwin-w32 build

        Suggested by Eli Zaretskii in discussion of bug#18302.

        * src/image.c [HAVE_NTGUI]: Remove the unused macro
        PIXEL_ALREADY_TYPEDEFED.  On Cygwin, include "noX/xpm.h" instead of
        "X11/xpm.h".

        * configure.ac [CYGWIN && HAVE_W32]: Change the xpm test to use
        "noX/xpm.h".  Don't add a -I switch to CPPFLAGS.

2016-06-14  Noam Postavsky  <npostavs@gmail.com>

        Make python.el work in Emacs 24

        * lisp/progmodes/python.el: Bump version.
        (python-define-auxiliary-skeleton): Only use format-message if
        fbound (Bug#23126).

2016-06-13  Ken Brown  <kbrown@cornell.edu>

        Avoid compiler warning

        * src/w32fns.c (deliver_wm_chars): Add 'const' to declaration of
        'type_CtrlAlt'.

2016-06-13  Paul Eggert  <eggert@cs.ucla.edu>

        Call tzset after setting TZ

        * src/editfns.c (tzlookup): Call tzset after setting TZ, so that
        the setting change propagates into Emacs local time (Bug#23600).
        (emacs_setenv_TZ): Clarify comments.

2016-06-13  Paul Eggert  <eggert@cs.ucla.edu>

        Update texinfo.tex

        * doc/misc/texinfo.tex: Update from gnulib.

2016-06-12  Paul Eggert  <eggert@cs.ucla.edu>

        New macro GNUC_PREREQ for GCC version

        * src/conf_post.h (GNUC_PREREQ): New macro.
        Change uses of __GNUC_MINOR__ and __GNUC_PATCHLEVEL__ to use this
        macro instead, for clarity and consistency.
        (PRINTF_ARCHETYPE): New macro.  Define it to __gnu_printf__ only
        if glibc, since non-GNU platforms don’t necessarily support GNU
        printf formats.
        (ATTRIBUTE_FORMAT_PRINTF): Use it.

2016-06-12  Nicolas Petton  <nicolas@petton.fr>

        * lisp/emacs-lisp/seq.el (seq-drop): Better list implementation

2016-06-12  Eli Zaretskii  <eliz@gnu.org>

        Fix printf-related compilation warnings on MinGW

        * src/conf_post.h (ATTRIBUTE_FORMAT_PRINTF) [__MINGW32__]: Use
        '__ms_printf__', not '__gnu_printf__', as the latter is not what
        MS 'printf' supports, and causes bogus compilation warnings.
        * src/lisp.h (pI) [__MINGW32__]: Define to "I64", as MS 'printf'
        doesn't support the "ll" modifier.

2016-06-11  Paul Eggert  <eggert@cs.ucla.edu>

        emacs_strerror cleanups

        * src/buffer.c, src/emacs.c, src/lread.c: Don’t include coding.h;
        no longer needed, now that emacs_strerror is declared by lisp.h.
        * src/coding.c (emacs_strerror): Remove; moved to emacs.c.
        * src/coding.h (emacs_strerror) [emacs]: Remove decl; moved
        to lisp.h.
        * src/emacs.c (emacs_strerror): Move here from coding.c.  Do not
        convert result string; this is now the caller’s responsibility,
        as some need conversion and others don’t.
        * src/fileio.c (report_file_errno, report_file_notify_error):
        Use emacs_strerror rather than rolling it ourselves.
        * src/lisp.h (emacs_strerror): Move decl here from coding.h.
        * src/lread.c (dir_warning): Just call emacs_strerror rather than
        both strerror and emacs_strerror.  Convert its result from
        locale-coding-system, since it no longer does that conversion.
        * src/sound.c (sound_perror):
        * src/sysdep.c (emacs_perror, str_collate):
        Use emacs_strerror, not strerror.

2016-06-10  David Reitter  <david.reitter@gmail.com>

        Prevent compiler warning for unused arguments

        * lisp/international/ucs-normalize.el
        (ucs-normalize-hfs-nfd-pre-write-conversion):
        Prevent compiler warning for unused arguments, add comment.

2016-06-10  Paul Eggert  <eggert@cs.ucla.edu>

        Catch malloc_get_state, malloc_set_state failure

        This should help insulate Emacs better from configuration screwups.
        Future versions of the GNU C library are planned to deprecate
        these functions, but will continue to support them in
        already-built-and-dumped Emacs executables.
        * src/alloc.c (malloc_initialize_hook) [DOUG_LEA_MALLOC]:
        Abort if malloc_set_state fails.
        (alloc_unexec_pre) [DOUG_LEA_MALLOC]:
        Report malloc_get_state failure, and exit.

2016-06-10  Eli Zaretskii  <eliz@gnu.org>

        Show returned value after gdb-mi "finish" command

        * lisp/progmodes/gdb-mi.el (gdb-stopped): Display the expected
        "Value returned" message in response to "finish", when not
        produced by GDB/MI.  (Bug#23720)

2016-06-10  David Reitter  <david.reitter@gmail.com>

        Simplify pre-write-conversion for utf-8-hfs coding system

        * lisp/international/ucs-normalize.el
        (ucs-normalize-hfs-nfd-pre-write-conversion): Refactor.

        May address an issue where Emacs consumed large amounts of CPU
        because of neverending toolbar updating (which was caused
        by, but also called this function).

2016-06-09  Martin Rudalics  <rudalics@gmx.at>

        Revert "Bind `widget-button-click' to mouse-1/-2 instead of down-mouse-1/-2"

        * lisp/wid-edit.el (widget-keymap): Bind `widget-button-click'
        to mouse-1/-2 instead of down-mouse-1/-2.  Suggested by Stefan
        Monnier.  (Bug#19185, Bug#20398)

        This reverts commit 72166f2f3dba18f1217c666574032f5a0351ed65.

        That commit did more harm than good (Bug#23571).

2016-06-09  Paul Eggert  <eggert@cs.ucla.edu>

        Port __builtin_assume_aligned to Sun C 5.13

        * src/conf_post.h (__builtin_assume_aligned):
        Fix typo: the extra arg did not conform to C99.

2016-06-09  Paul Eggert  <eggert@cs.ucla.edu>

        Prefer getsockopt to getpeername on non-MS-Windows

        * admin/CPP-DEFINES: Remove HAVE_GETPEERNAME.
        * configure.ac: Don’t check for getpeername.
        * src/process.c (wait_reading_process_output) [!WINDOWSNT]:
        Use getsockopt even if not GNU/Linux, as the platforms where
        getsockopt used to hang are no doubt long dead.

2016-06-09  Paul Eggert  <eggert@cs.ucla.edu>

        Fix XFASTINT of non-fixnum in process status

        * src/process.c (decode_status): 3rd arg is now Lisp_Object *,
        not int *, and is not decoded.  All uses changed.
        (status_message): Do not assume ‘failed’ code is an integer.
        * src/process.h: Document codes better.

2016-06-09  Glenn Morris  <rgm@gnu.org>

        Make messcompat.el obsolete.

        * lisp/obsolete/messcompat.el: Move here from lisp/gnus.

        Nowadays GCC is smarter, or the Emacs code has mutated, or both,

        Port to platforms where rlim_max < 0

        * src/emacs.c (main): Do not treat a negative rlim_max as a limit;
        this can happen if a special value like RLIM_INFINITY is negative.

        Robustify stack-size calculation

        Fix handling of ‘mouse-on-link-p’.

        If ‘mouse-on-link-p’ returns a string or vector, the first element

        happen if the return value is not a string or vector.  See
        docstring of ‘mouse-on-link-p’ and Bug#23288.

        CC Mode now uses the new :after-hook feature of define-derived-mode

        It now runs internal variable setting functions after the mode hooks, no
        longer runs the mode hooks twice, and declares the configuration variables for
        noise macros and macros with semicolons as safe variables (when given suitable
        arguments).

        Fixes bug #16759 and bug #23476.

        back into the C Mode value.

        Call hack-local-variables from major modes rather than from file visiting

        This prevents file/directory local variables from being lost when the major
        mode is set or changed.

        This fixes bug #15577 and bug #23407.

        * lisp/files.el (normal-mode): Call `hack-local-variables' when the major mode
        function hasn't already done so.
        (hack-local-variables): Rename parameter `mode-only' to `handle-mode', make
        its previous non-nil setting be t, and introduce the following action for a
        non-nil non-t value: apply all settings apart from `mode'.

        * lisp/subr.el (run-mode-hooks): call `hack-local-variables' for buffers
        which are visiting files.

        * doc/emacs/custom.texi (File Variables): Note that setting a major mode also
        sets file variables.
        (Directory Variables): Note that `mode', `eval', and `unibyte' can be set as
        dir local variables, but `coding' can't.

        * doc/lispref/modes.texi (Major Mode Conventions): Say that `run-mode-hooks'
        also calls `hack-local-variables'.
        (Auto Major Mode): Say that `find-file' no longer runs `hack-local-variables',
        as from 25.2.  Remove vagueness from `normal-mode' and `set-auto-mode' by
        saying that the mode IS SET, not merely "selected" or "chosen".
        (Mode Hooks): Document change to `run-mode-hooks'.

        Call va_end in boot_error

        * src/gnutls.c (boot_error): A recent change added a function
        to signal an error or return an error code. That function uses
        a variadic argument list to populate an error message
        string. However, it missed calling va_end after using the
        variadic argument list.

        modified the set_network_socket_coding_system function to take
        arguments host, service, and name. However, those arguments
        appear to be swapped.

        Revert "alas, a map can have only one parent"

        This reverts commit d05806fda1cbba2db112bc783597fbe9d27175b2.

        This had already been fixed by using `make-composed-map'.  And
        we don't want image-map to inherit from special-mode-map, anyway.

        New function ‘char-from-name’

        This also fixes the mishandling of "\N{CJK COMPATIBILITY
        IDEOGRAPH-F900}", "\N{VARIATION SELECTOR-1}", etc.
        Problem reported by Eli Zaretskii in:
        https://lists.gnu.org/r/emacs-devel/2016-04/msg00614.html
        * doc/lispref/nonascii.texi (Character Codes), etc/NEWS: Document this.
        * lisp/international/mule-cmds.el (char-from-name): New function.
        (read-char-by-name): Use it.  Document that "BED" is treated as
        a name, not as a hexadecimal number.  Reject out-of-range integers,
        floating-point numbers, and strings with trailing junk.
        * src/lread.c (character_name_to_code): Call char-from-name
        instead of inspecting ucs-names directly, so that we handle
        computed names like "VARIATION SELECTOR-1".  Do not use an auto
        string, since char-from-name might GC.

        c-forward-<>-arglist no longer directly applies face properties in Java Mode.

        This allows the calling of c-restore-<>-properties from c-common-init without
        the test suite giving spurious errors.

        * lisp/progmodes/cc-engine.el (c-forward-<>-arglist): Remove the form that
        sets face properties.
        (c-forward-<>-arglist-recur): Reformulate the bit that handles types inside
        template brackets using c-inside-<>-type-key.  Don't bind
        c-record-type-identifiers or c-record-found-types around the recursive call,
        allowing positions of found types to flow back to the caller.

        * lisp/progmodes/cc-langs.el (c-inside-<>-type-kwds, c-inside-<>-type-key):
        new lang consts/var.

        Add fontification for a C declaration which looks like a function call.

        For example, "t1 *fn (t2 *b);".

        * lisp/progmodes/cc-engine.el (c-forward-decl-or-cast-1): Add new variable
        at-decl-start, setting it to whether the putative decl starts immediately
        after ; or { or }.  Accept such a construct as a decl when at-decl-start is
        non-nil.

        * lisp/progmodes/cc-langs.el (c-pre-start-tokens): New language variable.

        * lisp/w32-fns.el (w32-convert-standard-filename): Don't mirror
        slashes into backslashes.  This avoids producing ugly file names,
        and is deemed no longer necessary, and should certainly be
        unrelated to which shell is in use.

        returned `unregistered' before.  Remove all checks comparing
        invocations with the backend passed in explicitly and without.

        Allow _ characters in SQL prompts

        Fixes issue 22596, whereby "_" is now not considered a word constituent
        character in sql-interactive-mode, so prompts like "foo_dev# " are not
        correctly detected. Rather than piggy-back on the symbol table, we
        explicitly match against alphanumeric chars or "_".

        like "\N{U+-0}" and null bytes in \N escapes.  Reject floating
        point in \N escapes instead of returning garbage.  Use
        AUTO_STRING_WITH_LEN to lessen pressure on the garbage collector.
        * test/src/lread-tests.el (lread-char-number, lread-char-name)
        (lread-string-char-number, lread-string-char-name):
        Test runtime behavior, not compile-time, as the test framework
        is not set up to test compile-time.

        Mark as obsolete, as it is now just an alias or narrow wrapper
        around format-time-string.
        * src/editfns.c (tzlookup): Also support integer OFFSET and
        list (OFFSET ABBR) as time zone rules.
        (Fencode_time): No longer need a special case for a cons ZONE.
        (Fcurrent_time_zone): If the time zone string is missing, compute
        it the same way the other new code does.

        Port redirect-debugging-output to MS-Windows

        Suggested by Eli Zaretskii in:
        https://lists.gnu.org/r/emacs-devel/2016-04/msg00037.html
        * src/print.c [WINDOWSNT]: Include sys/socket.h.

        Port redirect-debugging-output to non-GNU/Linux

        Problem reported by Kylie McClain for musl in:
        https://lists.gnu.org/r/emacs-devel/2016-03/msg01592.html
        * etc/DEBUG, etc/NEWS: Mention this.

        * src/regex.c (xmalloc, xrealloc):
        Prefer symbolic names like STDERR_FILENO to magic numbers like 2,
        to make file-descriptor manipulation easier to follow.
        * src/emacs.c (relocate_fd) [!WINDOWSNT]: Remove; no longer needed
        now that we make sure stdin, stdout and stderr are open.  All uses
        removed.
        (main): Make sure standard FDs are OK.  Prefer symbolic names like
        EXIT_FAILURE to magic numbers like 1.  Use bool for boolean.
        * src/lisp.h (init_standard_fds): New decl.
        * src/print.c (WITH_REDIRECT_DEBUGGING_OUTPUT) [GNU_LINUX]:
        Remove; no longer needed.
        (Fredirect_debugging_output): Define on all platforms, not just
        GNU/Linux.  Redirect file descriptor, not stream, so that the code
        works even if stderr is not an lvalue.  Report an error if the
        file arg is neither a string nor nil.
        (syms_of_print): Always define redirect-debugging-output.
        * src/sysdep.c (force_open, init_standard_fds): New functions.

        Rename C names to match Lisp symbols better

        This was inspired by commit e65c3079c65595d95749348366af9811fafff062,
        which fixed a bug where the C name for a symbol disagreed with the
        symbol name itself.  Fix other instances of disagreements that I found.
        Although this doesn’t fix a bug, it should make code easier to follow.
        The remaining disagreements are idiosyncratic: Qminus, Qplus,
        Qsans__serif, Qbackquote, Qcomma, Qcomma_at, Qcomma_dot.
        All uses changed.
        * src/alloc.c (QAutomatic_GC): Rename from Qautomatic_gc.
        * src/dbusbind.c (QCsystem): Rename from QCdbus_system_bus.
        (QCsession): Rename from QCdbus_session_bus.
        (QCtimeout): Rename from QCdbus_timeout.
        (QCbyte): Rename from QCdbus_type_byte.
        (QCboolean): Rename from QCdbus_type_boolean.
        (QCint16): Rename from QCdbus_type_int16.
        (QCuint16): Rename from QCdbus_type_uint16.

        Amend parse-partial-sexp correctly to handle two character comment delimiters

        Do this by adding a new field to the parser state: the syntax of the last
        character scanned, should that be the first char of a (potential) two char
        construct, nil otherwise.
        This should make the parser state complete.
        Also document element 9 of the parser state.  Also refactor the code a bit.

        * src/syntax.c (struct lisp_parse_state): Add a new field.
        (SYNTAX_FLAGS_COMSTARTEND_FIRST): New function.
        (internalize_parse_state): New function, extracted from scan_sexps_forward.
        (back_comment): Call internalize_parse_state.
        (forw_comment): Return the syntax of the last character scanned to the caller
        when that character might be the first of a two character construct.
        (Fforward_comment, scan_lists): New dummy variables, passed to forw_comment.
        (scan_sexps_forward): Remove a redundant state parameter.  Access all `state'
        information via the address parameter `state'.  Remove the code which converts
        from external to internal form of `state'.  Access buffer contents only from
        `from' onwards.  Reformulate code at the top of the main loop correctly to
        recognize comment openers when starting in the middle of one.  Call
        forw_comment with extra argument (for return of syntax value of possible first
        char of a two char construct).
        (Fparse_partial_sexp): Document elements 9, 10 of the parser state in the
        doc string.  Clarify the doc string in general.  Call
        internalize_parse_state.  Take account of the new elements when consing up the
        output parser state.

        * doc/lispref/syntax.texi: (Parser State): Document element 9 and the new
        element 10.  Minor wording corrections (remove reference to "trivial
        cases").
        (Low Level Parsing): Minor corrections.

        * etc/NEWS: Note new element 10, and documentation of element 9 of parser
        state.

        Stop calling res_init

        Emacs shouldn’t need to call res_init any more, now that nscd or
        equivalent is everywhere.  On modern systems, calling res_init
        simply slows Emacs down.  On ancient systems lacking nscd Emacs
        will still work well enough with this change; it’s just that it
        won’t respond to changes in /etc/resolv.conf.
        * configure.ac (HAVE_RES_INIT): Remove.  Worry about -lresolv only
        when configured --with-hesiod.  Hesiod is still used; see, e.g.:

        When configuring with --enable-gcc-warnings, also enable

        This addresses only a theoretical problem, as in practice these
        object sizes are less than 2**31, but we might as well use the
        same style here as elsewhere in Emacs.
        (string_integer_p): Remove; all uses removed.
        (Fmake_network_process): Check that port number is in range.
        When converting an integer-string service, rely on strtol

        Fix `window-configuration-change-hook' and `window-size-change-functions'

        (1) Run `window-configuration-change-hook' if and only if at least
        one window was deleted or created or shows another buffer since
        last redisplay.

        (2) Run `window-size-change-functions' if and only if at least
        one window changed its size since last redisplay (in a few cases
        `window-size-change-functions' will also run when no window
        changed its size).

        (3) Provide two functions `window-pixel-height-before-size-change'
        and `window-pixel-width-before-size-change' that allow to easily
        detect which window changed size.

        really changed.

        functions `window-pixel-height-before-size-change' and
        `window-pixel-width-before-size-change'.

        converted to a list of 16 bit quantities by
        conv_sockaddr_to_lisp(). conv_lisp_to_sockaddr() should follow the

        quantities.

        * lisp/gnus/message.el (message-beginning-of-header): New function which
        moves point to the beginning of a mail header.  The function is aware of

        value.
        (message-beginning-of-line): Function is now aware of folded headers and
        either moves point to the indentation of a header or, in visual-line-mode,

        Performance improvements for vc-hg

        Teach vc-hg how to read some Mercurial internal data structures,
        allowing us to avoid the need to run hg status -A, which is very slow
        for large repositories.  Fall back to running hg if anything looks
        funny.  vc-hg now puts the _working directory_ revision in the
        modeline instead of the file revision, which greatly improves
        performance and which allows us to again skip running hg in the case
        that we have an active bookmark.

        Just for the record, the test for that case could have been
        (XLI (init) % ((EMACS_UINT) -1 / UCHAR_MAX) == 0) (!),
        assuming the typical platform with no padding bits and where
        conversion to int omits the most significant bits.

        The current version of HTTP/1.1 (RFC 7231) no longer requires

        Remove packages obsoleted before Emacs 24.

        In accordance with the policy discussed in the emacs-devel list,
        packages that have been obsoleted for a full major release cycle are up
        for deletion.

        This removes almost all packages that are now eligible for deletion,
        with the exception of "cl-compat", which seems it is likely to still be
        used, and "optional", which offers some functionality that doesn't have
        a replacement yet.

2016-02-03  Paul Eggert  <eggert@cs.ucla.edu>

        Mention context when resume from emergency escape

        Support new arguments --help, all, autoconf, git.
        By default, just do autoconf-related configuration, not git.
        Prefer 'echo' to 'cat <<EOF ...', as this tends to avoid temp files.
        If GNU cp is available, use it to backup .git/config before
        changing it.  When configuring git, chatter about what is being
        done, and configure git to check hashes.  Avoid some duplicate
        file name specification when creating git hooks.

2016-01-30  Paul Eggert  <eggert@cs.ucla.edu>

        Include <malloc.h> when advisable

        This should help insulate us better from future glibc changes.
        It is good hygiene to include .h files for APIs that Emacs uses.
        Fix type clashes between Emacs and GNU <malloc.h> (Bug#22086).
        * configure.ac: Check for malloc.h.

        * src/lisp.h (alloc_unexec_pre, alloc_unexec_post) [!DOUG_LEA_MALLOC]:
        Declare unconditionally.
        * src/unexcw.c, src/unexelf.c (bss_sbrk_did_unexec): Remove decl.

        * src/emacs.c (main):
        * src/xsmfns.c (smc_save_yourself_CB, x_session_initialize):
        Use emacs_get_current_dir_name, not get_current_dir_name.
        * src/conf_post.h (aligned_alloc) [HYBRID_MALLOC && emacs]: New macro.
        (HYBRID_GET_CURRENT_DIR_NAME, get_current_dir_name): Remove.

        * src/gmalloc.c [HYBRID_MALLOC]:
        Include "sheap.h" rather than declaring its contents by hand.
        (get_current_dir_name, gget_current_dir_name)
        (hybrid_get_current_dir_name): Remove.
        (emacs_abort): Remove duplicate decl.

        (bss_sbrk_ptr): Now static and private.
        (bss_sbrk_did_unexec): Now bool.
        (BLOCKSIZE): Remove, to avoid GCC warning about its not being used.
        (bss_sbrk): Don't treat request_size 0 as special, since the code
        works without this being a special case.
        Avoid overflow if request size exceeds INT_MAX.
        (report_sheap_usage): Remove; now done in emacs.c.
        * src/sheap.h: New file.
        * src/sysdep.c (get_current_dir_name): Remove macro.
        Include "sheap.h".
        (emacs_get_current_dir_name): Rename function from

        this is simpler.
        (Bug#22086)

2016-01-30  Paul Eggert  <eggert@cs.ucla.edu>

        Report static heap usage on non-Cygwin, too

        * src/emacs.c (Fdump_emacs) [HYBRID_MALLOC]: Report sheap usage here ...
        * src/unexcw.c (unexec): ... instead of here, since sheap can be used
        on platforms other than Cygwin (Bug#22086).

        Define bss_sbrk_did_unexec (Bug#22086).

2016-01-30  Wolfgang Jenkner  <wjenkner@inode.at>

        Link temacs with gnulib compiled with -Demacs

        This is done to support HYBRID_MALLOC, since some static variables
        (e.g., last_environ in putenv.c) hold pointers to memory malloced
        before dumping (Bug#22086).
        * lib/Makefile.am: Add incantation to install libegnu.a.
        * src/Makefile.in ($(lib)/libgnu.a): Replace with libegnu.a
        (temacs$(EXEEXT)): Use it.

2016-01-30  Wolfgang Jenkner  <wjenkner@inode.at>

        Internal linkage for gmalloc etc. if HYBRID_MALLOC

        This avoids clashes with symbols if the after-dump malloc is
        derived from Doug Lea's implementation (Bug#22086).

        * src/gmalloc.c (emacs_abort, __morecore, __default_morecore):
        Move declarations up.  For HYBRID_MALLOC, turn all `extern'
        declarations below to `static' ones.
        (aligned_alloc): Declare for !MSDOS as well.
        (heapsize, _fraghead): Move resp. copy declaration downwards.
        For HYBRID_MALLOC, conditionalize out the other definitions,
        since the previous `static' declarations double as tentative
        definitions, anyway.
        (_malloc, _free, _realloc, __free_hook, _aligned_blocks)
        (__realloc_hook, __memalign_hook): Conditionalize out.
        (cfree, memalign, valloc): Ditto.

        renamed cell by testing `ses-cell' property to :ses-named, rather than
        comparing name to corresponding standard name. Set rowcol of renamed
        cell into the hashmap --- `ses-cell' property must not be used for
        that as the same name can be used for different locations in different
        SES sheets ; 2) use `local-variable-if-set-p' rather than `boundp' and
        `local-variable-p' to check if cell name is already in use in this
        sheet or needs initialization.
        (ses-relocate-all): Cell value relocation : 1) like for name
        relocation use the `ses-cell' property rather than comparing actual
        name to corresponding standard name. 2) Correct bug introduced in
        2011-12-27T19:30:39Z!vincentb1@users.sourceforge.net, as the test was
        made the other way round than the intention --- ie value relocation
        was disabled for standard cell, not for renamed cell as was the
        intention.
        (ses-relocate-all): Add loop for unbinding deleted renamed cells
        names.
        (ses-killbuffer-hook): new defun.
        (ses-mode): Add the ses--ses-buffer-list maintenance mechanism ---
        kill buffer hook, plus pushing current buffer if new in list.
        (ses-delete-row, ses-delete-column): Collect deleted renamed cells
        into `ses--in-killing-named-cell-list'.
        (ses-rename-cell): Remove update of variable
        `ses--renamed-cell-symb-list', this variable is renamed to
        `ses--in-killing-named-cell-list', and its setting is done in
        functions `ses-delete-row' and , `ses-delete-column' now.
        (ses-rename-cell): Change correction of
        2015-12-30T23:10:37Z!vincentb1@users.sourceforge.net concerning
        computation of the range over which `cursor-intangible' property was
        to be updated. This correction was ok for non spilling cells, but not
        for cells spilling over following blank cells. Simply use
        `next-single-property-change' rather than computing the end column
        from column widths.

        Correct ses-rename-cell cursor-intangible text prop updating.

        There were two problems:

        - First ses-rename-cell has to work when called non interactively
          (with non-nil CELL argument), so in this case the start pos of
          put-text-property cannot be plainly (point), you need a
          ses-goto-print call before

        - Second, the range itself was computed erroneously, only the first
          char was affected instead of the full cell width. This was not
          noticeable prior to changes (Deprecate `intangible' and
          `point-entered' properties) made by Stefan on 2015-04-13T19:51:15Z

        * lisp/ses.el (ses-rename-cell): Correct computation of position range
        to which the 'cursor-intangible text property has to be set to cell
        new name.

        Don't fake empty cells value by "" when printing with a lambda.

        When using a lambda expression printer function the user should be
        free to format differently a really empty cell, ie. containing nil,
        from a cell containing an empty string "".

        * lisp/ses.el (ses-call-printer): Replace `(or value "")' by just
        `value' in the case of a lambda expression printer function.

        * doc/misc/ses.texi (Printer functions): Add example and
        description about lambda expression printer function handling all
        the possible values, including unexpected ones.

        Quick temporary hack to fix curcell refreshing.

        The problem was caused by change: 2015-04-13 Deprecate `intangible'
        and `point-entered' properties. The problem is that this change has
        removed the (setq ses--curcell t) setting in the ses-command-hook
        function.

        * lisp/ses.el (ses-check-curcell): replace `(eq ses--curcell t)' by just `t' as
        a condition to call function `ses-set-curcell'. Comment this as a quick
        temporary hack to make it work, as I don't know yet whether a definite
        correction would be to make the ses-set-curcell at every ses-check-curcell,
        or to revert to the previous approach, ie marking ses--curcell as out-of-date
        at every potentially cursor motion command.

        * lisp/calculator.el (calculator-define-key): Silence warning

        ...about unknown calculator-mode-map.

2015-11-29  Eli Barzilay  <eli@barzilay.org>

        * lisp/calculator.el: more improvements and bugfixes.

        - Mark `calculator-paste-decimals' as obsolete.  (It wasn't having an
          effect anyway.)

        - Simplify `calculator-number-to-string' by throwing most of the work
          onto `number-to-string', leaving just some tweaks for decimal inputs.
          This leads to some minor changes, for example, pasting "1x1" in hex
          mode would warn that "x" is ignored and result in "11" (and it wasn't
          done in decimal mode), whereas now it just ignores everything from the
          "x" and on and result in a "1" just like in decimal input mode.  Also,
          overflows are left for `number-to-string' to deal with.

        - `calculator-paste' is very simple as a result.

        - Extend the simplified `calculator-paste': with a prefix argument it
          pastes a string as if the characters were entered.  This can be used
          to reduce expressions, but note that it's a simple literal operation,
          so precedence can be messed, a number can be paster while entering a
          number, spaces and newlines matter, etc.

        - Fix a minor bug where "e+" in hex mode wouldn't use "+" as an
          operator.

        - Fix a bug in `calculator-put-value': avoid grouping in the display
          that is used to construct `calculator-curnum'.  This would trigger
          when pasting or getting a value from a register in some radix mode
          with a large enough value.  Another fix: make the output radix equal
          the input one, otherwise numbers could be converted twice.

2015-11-29  Eli Barzilay  <eli@barzilay.org>

        * lisp/calculator.el: Re-do key bindings.

        Use a helper function that arranges a parent keymap that binds alternate
        case keys so if some letter key is unbound and it's un/shifted version
        is, it will get used.  This makes the global-map trickery unnecessary.

        Also switch to passing strings that name keys through `kbd'.

2015-11-29  Eli Barzilay  <eli@barzilay.org>

        * lisp/calculator.el: improve radix modes

        Fix prompt for some input radix with decimal output (eg, "BD" instead of
        the incorrect "B="); also, some minor docstring tweaks for these.

2015-11-29  Eli Barzilay  <eli@barzilay.org>

        * lisp/calculator.el: better reading of register names

        Use `register-read-with-preview' with a dynamically bound
        `register-alist' and a proper preview function to read register names.

2015-11-29  Eli Barzilay  <eli@barzilay.org>

        * lisp/calculator.el: General improvements

        Use things like `when', `unless', and `push'.

        Improve `calculator-last-input' so it doesn't barf when hitting `F1' in
        non-electric mode.

2015-11-28  Michael Albinus  <michael.albinus@gmx.de>

        Fix a problem with gfilenotify in filenotify-tests.el

        * test/lisp/filenotify-tests.el

        (file-notify--test-with-events): EVENTS can also be a list of lists.

        Add test targets without directory names.

         * (test/Makefile.in): Extend test_template to add two targets for each

        * lisp/emacs-lisp/package.el: Require url-handlers

2015-11-27  Phillip Lord  <phillip.lord@russet.org.uk>

        Move elisp-mode-tests to new function names.

         find-defs-defun-el-defvar-c): Call `elisp--xref-find-definitions'.

        * lisp/emacs-lisp/package.el: Declare `url-insert-buffer-contents'

        Merge branch 'feature/standard-test-location'

        * lisp/emacs-lisp/eieio.el: Add some default implementations

        (standard-class): Mark it obsolete.
        (slot-missing): Give it a default implementation.

        (object-print): Give it a default implementation.

        (c-save-buffer-state): Use with-silent-modifications when available.

2015-11-18  Michael Albinus  <michael.albinus@gmx.de>

        Further fixes for kqueue.

        * lisp/filenotify.el (file-notify-callback): Raise also event if
        directory name matches.
        (file-notify-add-watch): Add `create' to the flags for `kqueue'.

        * src/kqueue.c (kqueue_generate_event): Use watch_object as
        argument instead of ident.  Remove callback argument.  Adapt
        callees.  Check actions whether they are monitored flags.

        * test/automated/file-notify-tests.el (file-notify--test-library):

        for kqueue.  In case of deleting a directory, there are two
        `deleted' events.

2015-11-17  João Távora  <joaotavora@gmail.com>

        Minor fix to comment indentation and typo in last commit

        * lisp/linum.el (linum-update-window): Fix comment indentation and
        a typo.

2015-11-17  João Távora  <joaotavora@gmail.com>

        linum-mode plays more nicely with other margin-setting extensions

        linum.el will only modify the left margin if it needs to, and will
        only reset the it back to 0 if it guesses that no-one has touched that
        margin in the meantime.

        As such, this is a more of a workaround than an actual fix, but fixes
        the problems described in bug#20674 regarding the interaction with
        modes such as darkroom-mode and olivetti-mode.

        A similar fix was committed to nlinum.el in ELPA.git's
        e7f5f549fbfb740b911fb7f33b42381ecece56d8

        * lisp/linum.el (linum-delete-overlays): Restore margins more
        criteriously.
        (linum-update-window): Set margins more criteriously.

2015-11-17  Michael Albinus  <michael.albinus@gmx.de>

        Code cleanup of kqueue.c

        * src/kqueue.c (kqueue_directory_listing): Skip "." and "..".
        (kqueue_compare_dir_list): Do not loop when calling
        directory_files_internal.  Remove checks for "." and "..", this is
        done in kqueue_directory_listing now.
        (Fkqueue_add_watch): Check for proper emacs_open flags.

2015-11-16  Daiki Ueno  <ueno@gnu.org>

        * lisp/image-mode.el: Support encrypted file

        (image-toggle-display-image): Read content from the buffer instead
        of the file, if the buffer holds a decrypted data.  (Bug#21870)

2015-11-16  Michael Albinus  <michael.albinus@gmx.de>

        Doc changes for kqueue

        * doc/lispref/os.texi (File Notifications): Add kqueue as backend.
        Fix some glitches in the example.

2015-11-16  Michael Albinus  <michael.albinus@gmx.de>

        Finish implementation in kqueue.c

        * src/kqueue.c (kqueue_directory_listing, kqueue_callback):
        Simplify access to list.
        (kqueue_compare_dir_list): Simplify access to list.  Raise
        `delete' event if directory does not exist any longer.  Otherwise,
        wait until directory contents has changed.  Fix error in check.

2015-11-15  Michael Albinus  <michael.albinus@gmx.de>

        * lisp/filenotify.el (file-notify-add-watch): Fix thinko.

2015-11-15  Juanma Barranquero  <lekktu@gmail.com>

        * lisp/progmodes/verilog-mode.el (verilog-save-buffer-state): Add backquote

2015-11-15  Artur Malabarba  <bruce.connor.am@gmail.com>

        * lisp/emacs-lisp/package.el: Fix a decoding issue

        (package--with-response-buffer): Use `url-insert-buffer-contents'.
        The previous code had some issues with decoding. Refactoring that
        function allows us to use the decoding from url-handlers while still
        treating both sync and async requests the same.

        * lisp/url/url-handlers.el (url-insert-file-contents): Move some code to
        `url-insert-buffer-contents'.
        (url-insert-buffer-contents): New function

        (package--with-work-buffer-async): Reimplement as
        `package--with-response-buffer'.
        (package--with-work-buffer): Mark obsolete.
        (package--with-response-buffer): New macro. This is a more self
        contained and less contrived version of
        `package--with-work-buffer-async'.  It uses keyword arguments,
        doesn't have async on the name, doesn't fallback on
        `package--with-work-buffer', and has _much_ simpler error
        handling.

        (package--check-signature, package--download-one-archive)
        (package-install-from-archive, describe-package-1): Use it.

        (package--download-and-read-archives): Let
        `package--download-one-archive' take care of calling
        `package--update-downloads-in-progress'.

2015-11-15  Stefan Monnier  <monnier@iro.umontreal.ca>

        * lisp/progmodes/verilog-mode.el: Use with-silent-modifications

        (verilog-save-buffer-state): Use with-silent-modifications when available.
        (verilog-save-font-no-change-functions): Don't bind
        before/after-change-functions if it's not needed.

2015-11-15  Michael Albinus  <michael.albinus@gmx.de>

        More work on kqueue

        * lisp/filenotify.el (file-notify-callback): Handle also the

        * src/kqueue.c (kqueue_directory_listing): New function.
        (kqueue_generate_event): New argument FILE1.  Adapt callees.

        (gitmerge-setup-log-buffer): Use the same symmetric range as in
        `gitmerge-missing'.

2015-11-14  David Engster  <deng@randomsample.de>

        gitmerge: Try to detect cherry-picks

        * configure.ac:
        * msdos/sed2v2.inp: Bump version to 25.1.50.

2015-11-13  Wilson Snyder  <wsnyder@wsnyder.org>

        Update verilog-mode.el to 2015-11-09-b121d60-vpo.

        * lisp/progmodes/verilog-mode.el (verilog-auto, verilog-delete-auto)
        (verilog-modi-cache-results, verilog-save-buffer-state)
        (verilog-save-font-no-change-functions): When internally suppressing change
        functions, use `inhibit-modification-hooks' and call
        `after-change-functions' to more nicely work with user hooks.
        Reported by Stefan Monnier.

        (verilog-auto, verilog-delete-auto, verilog-delete-auto-buffer):
        Create `verilog-delete-auto-buffer' to avoid double-calling
        fontification hooks.

        (verilog-restore-buffer-modified-p, verilog-auto)
        (verilog-save-buffer-state): Prefer restore-buffer-modified-p over
