2014-09-30  Paul Eggert  <eggert@cs.ucla.edu>

        * alloc.c: Remove now-unnecessary check.
        Suggested by Dmitry Antipov in:
        http://lists.gnu.org/archive/html/emacs-devel/2014-09/msg00891.html

        * xterm.c (x_term_init): Allocate temps on stack, not on heap.

        * frame.c (x_set_frame_parameters): Port --enable-gcc-warnings
        to Ubuntu 14.04.1 x86-64.

        Simplify stack-allocated Lisp objects, and make them more portable.
        The build_local_string macro was used in two ways: (1) string
        literals for which scoped allocation suffices, and (2) file name
        components, where it's not safe in general to assume bounded-size
        ASCII data.  Simplify by defining a new macro SCOPED_STRING that
        allocates a block-scope string, and by using SCOPED_STRING for (1)
        and build_string for (2).  Furthermore, actually use stack
        allocation only for objects known to have sufficient alignment.
        This simpler implementation means Emacs can make
        USE_STACK_LISP_OBJECTS the default unless GC_MARK_STACK !=
        GC_MAKE_GCPROS_NOOPS.
        * lisp.h (GCALIGNED): Align even if !USE_STACK_LISP_OBJECTS,
        for fewer differences among implementations.
        (struct Lisp_String): Now GCALIGNED.
        (USE_STACK_LISP_OBJECTS): Default to true, since the
        implementation no longer insists on a nonempty GCALIGNED.
        But make it false if GC_MARK_STACK != GC_MAKE_GCPROS_NOOPS.
        (SCOPED_CONS_INITIALIZER): Remove, since it's no longer needed
        separately.  Move definiens to scoped_cons.  The old definition
        was incorrect when GCALIGNED was defined to be empty.
        (union Aligned_String): New type.
        (USE_STACK_CONS, USE_STACK_STRING): New constants, so that the
        implementation ports to compilers that don't align strictly enough.
        Don't worry about the union sizes; it's not worth bothering about.
        (scoped_cons, scoped_list1, scoped_list3, scoped_list4):
        Rewrite using USE_STACK_CONS.
        (scoped_cons): Assume the use of union Aligned_Cons.
        (lisp_string_size, make_local_string, build_local_string): Remove.
        Unless otherwise specified, all callers of build_local_string
        changed to use SCOPED_STRING.
        (SCOPED_STRING): New macro.
        * data.c (wrong_choice):
        * menu.c (single_menu_item):
        * process.c (Fformat_network_address):
        Hoist use of SCOPED_STRING out of a scope, so that its returned
        object lives long enough.
        * fileio.c (Fexpand_file_name): Use build_string, not SCOPED_STRING,
        as the string might be long or might not be ASCII.

2014-09-29  Eli Zaretskii  <eliz@gnu.org>

        * msdos.c (internal_terminal_init): Bump version to 25.

2014-09-29  Dmitry Antipov  <dmantipov@yandex.ru>

        Keep stack-allocated Lisp objects fast rather than versatile.
        * lisp.h (union Aligned_Cons) [!GCALIGNED]: Define as such.
        (SCOPED_CONS_INITIALIZER): New macro.

        (USE_LOCAL_ALLOCA): Remove.
        (local_cons, local_list1, local_list2, local_list3, local_list4):
        Remove.  Stack overflow checking makes them too slow.
        (make_local_vector): Likewise.  Also we just don't have enough
        users for it.
        (enum LISP_STRING_OVERHEAD): Remove.
        (local_string_init, local_vector_init): Remove prototypes.
        (make_local_string, build_local_string): Redesign to target short
        compile-time string constants, fall back to regular string allocation
        where appropriate.
        (lisp_string_size): New function.
        (verify_ascii) [ENABLE_CHECKING]: Add prototype.
        * alloc.c (local_string_init, local_vector_init): Remove.
        (verify_ascii) [ENABLE_CHECKING]: New function.
        * buffer.c, charset.c, chartab.c, data.c, editfns.c, emacs.c, fileio.c:
        * fns.c, font.c, fontset.c, frame.c, keyboard.c, keymap.c, lread.c:
        * menu.c, minibuf.c, process.c, textprop.c, xdisp.c, xfns.c, xfont.c:
        * xselect.c, xterm.c: All related users changed.

        incorrect definition.

2014-09-27  Stefan Monnier  <monnier@iro.umontreal.ca>

        * keyboard.c (track-mouse): Rename to internal--track-mouse.

        * lisp.mk (lisp): Add elisp-mode.elc.

2014-09-26  Paul Eggert  <eggert@cs.ucla.edu>

        * xfns.c (x_default_scroll_bar_color_parameter):
        Use USE_LOCAL_ALLOCA only if USE_TOOLKIT_SCROLL_BARS,
        to pacify --enable-gcc-warnings in non-scrollbar builds.

2014-09-26  Ken Brown  <kbrown@cornell.edu>

        * w32term.h (ALIGN_STACK): Fix the cpp condition.

2014-09-25  Eli Zaretskii  <eliz@gnu.org>

        * lisp.h (USE_STACK_LISP_OBJECTS): Default to false for 32-bit
        MinGW builds that use GCC before 4.2.

        Default to stack objects on DOS_NT platforms as well.
        * w32term.h (ALIGN_STACK) [__GNUC__]: Define to
        __attribute__((force_align_arg_pointer)) for GCC 4.2 and later.

2014-09-25  Martin Rudalics  <rudalics@gmx.at>

        * frame.c (frame_inhibit_resize):
        * widget.c (EmacsFrameResize):
        * window.c (resize_frame_windows, Fset_window_configuration):

        Remove code left dead after 2014-07-27 changes.

2014-09-25  Paul Eggert  <eggert@cs.ucla.edu>

        Fix local_cons etc. to not exhaust the stack when in a loop.
        Problem reported in:
        http://lists.gnu.org/archive/html/emacs-devel/2014-09/msg00696.html

        Put USE_LOCAL_ALLOCA at the start of the function.
        * fns.c (maybe_resize_hash_table): Use build_string instead of
        build_local_string, since we'd otherwise need a conditional
        USE_LOCAL_ALLOCA here, but this is just debugging output and is
        not worth the bother of optimization.
        * font.c (font_delete_unmatched): Remove by-hand code that
        observed MAX_ALLOCA limit, since it's now done automatically.
        * keymap.c (Fsingle_key_description): Put USE_SAFE_ALLOCA at top,
        since build_local_string needs its sa_alloc.
        * lisp.h (lisp_word_count): New function.
        (SAFE_ALLOCA_LISP): Use it.
        (USE_LOCAL_ALLOCA): New macro.

2014-09-24  Paul Eggert  <eggert@cs.ucla.edu>

        Default to stack objects on non-GNU/Linux, non-DOS_NT platforms.
        * lisp.h (USE_STACK_LISP_OBJECTS): Also default to true
        if !defined DOS_NT && !defined GNU_LINUX.  I've tested this on AIX
        and Solaris and it's likely to work on similar platforms.

        Avoid signed integer overflow when converting Time to ptrdiff_t.
        * keyboard.c (INPUT_EVENT_POS_MAX, INPUT_EVENT_POS_MIN):
        New macros.
        (position_to_Time, Time_to_position): New functions.
        (gen_help_event, kbd_buffer_get_event): Use them.
        * systime.h (Time) [emacs && !HAVE_X_WINDOWS]:
        Go back to plain 'unsigned long', so that 'Time' is the same
        for both X and non-X builds; this is less likely to cause surprise.
        * termhooks.h: Remove compile-time check that Time and ptrdiff_t
        are the same size; this is no longer required.

        * keyboard.c (make_lispy_event): Avoid unnecessary tests
        of bit 28 and of whether an unsigned value is negative.
        This simplifies the code a bit, and pacifies clang 3.4.

2014-09-24  Eli Zaretskii  <eliz@gnu.org>

        * systime.h (Time): Define as size_t, to be consistent with 64-bit
        Windows builds, where 'long' is a 32-bit type.

        * w32inevt.h (w32_console_mouse_position): Update the argument
        types to use 'Time'.

        * w32term.c (w32_mouse_position)
        (x_horizontal_scroll_bar_report_motion)
        (x_scroll_bar_report_motion): Update the argument types to use
        'Time'.

        * termhooks.h (enum scroll_bar_part): Begin from 0 to allow...
        (struct input_event): ...unsigned bitfields.  Likewise for
        `event_kind' member.  Prefer unsigned for `code' and 'modifiers'.

        (kbd_buffer_get_event): Adjust users.
        (scroll_bar_parts): Add Qnil to match scroll_bar_nowhere.
        (make_scroll_bar_position): New function, refactored out of...

        * nsterm.h (EmacsScroller): Use enum for `last_hit_part' member.
        * nsterm.m (ns_mouse_position, mouseUp):
        * term.c (term_mouse_position):
        * w32inevt.c (w32_console_mouse_position):
        * w32term.c (w32_mouse_position):
        * xterm.c (XTmouse_position): Use scroll_bar_above_handle.
        (x_send_scroll_bar_event, xm_scroll_callback, xg_scroll_callback):
        Prefer enum and explicit enum members to integers and numeric values.

        * chartab.c (uniprop_encode_value_numeric):
        * font.c (font_style_to_value): Use make_local_vector.
        (font_delete_unmatched): Use local_cons but respect MAX_ALLOCA.
        * keymap.c (append_key): Use scoped_list1.

        * lisp.h (USE_STACK_LISP_OBJECTS): Enable by default if GNU_LINUX
        && __GNUC__ && !__clang__.  Mention known problems.  Adjust comment.

        * xfns.c (xic_create_fontsetname):
        Don't assume output buffer is initially zero.

2014-09-23  Paul Eggert  <eggert@cs.ucla.edu>

        * lisp.h (lispstpcpy): Rename from lispstrcpy, and act like stpcpy.
        All callers changed.
        * xterm.c (x_term_init): Use new functionality to avoid two needs
        to compute a string length.

        * dispextern.h, xdisp.c (window_box_right_offset): Now static.

2014-09-23  Dmitry Antipov  <dmantipov@yandex.ru>

        More and more stack-allocated Lisp objects if USE_LOCAL_ALLOCATORS.
        * lisp.h (local_list4) [USE_LOCAL_ALLOCATORS]: New macro.
        [!USE_LOCAL_ALLOCATORS]: Fall back to regular list4.
        * frame.h (FRAME_PARAMETER): New macro.
        * dispnew.c (init_display):

        * xfns.c (x_default_scroll_bar_color_parameter)
        (x_default_font_parameter, x_create_tip_frame): Use it.
        * editfns.c (Fpropertize): Use local_cons.

        * xdisp.c (build_desired_tool_bar_string): Use local_list4.

2014-09-18  Paul Eggert  <eggert@cs.ucla.edu>

        Port USE_LOCAL_ALLOCATORS code to clang 3.4 x86-64.
        * lisp.h (USE_LOCAL_ALLOCATORS): Define only if __GNUC__ &&
        !__clang__.  This works with GCC and with clang and is safer for
        compilers we don't know about.
        (local_cons): Rename parameter to make capture less likely.

2014-09-17  Samuel Bronson  <naesten@gmail.com>

        * unexmacosx.c (copy_data_segment): Port to GCC 4.6+ (Bug#9927).

2014-09-17  Paul Eggert  <eggert@cs.ucla.edu>

        Fix minor problems found by static checking.
        * alloc.c, lisp.h (SAVE_TYPE_INT_OBJ, make_save_int_obj):
        Remove; now unused.
        * buffer.h (decode_buffer): Doc and indentation fixes.
        * fns.c (Qstring_collate_lessp, Qstring_collate_equalp): Now static.

2014-09-17  Dmitry Antipov  <dmantipov@yandex.ru>

        Avoid clang-specific warnings.
        * buffer.c (init_buffer): Shut up -Wself-assign.
        * process.c (server_accept_connection): Shut up -Wunsequenced.

2014-09-16  Daniel Colascione  <dancol@dancol.org>

        * fns.c (sxhash): For symbols, use address as hash code.

2014-09-16  Dmitry Antipov  <dmantipov@yandex.ru>

        If USE_LOCAL_ALLOCATORS, allocate even more Lisp objects on stack.
        * charset.c (load_charset_map_from_file): Use scoped_list2
        and build_local_string.
        * buffer.c (Fother_buffer, other_buffer_safely, init_buffer):
        * emacs.c (init_cmdargs, decode_env_path):
        * fileio.c (Fexpand_file_name):
        * fns.c (maybe_resize_hash_table) [ENABLE_CHECKING]:
        * frame.c (x_get_arg):
        * keyboard.c (safe_run_hooks_error):
        * lread.c (load_warn_old_style_backquotes):
        * xdisp.c (Fcurrent_bidi_paragraph_direction):
        * xfns.c (x_default_scroll_bar_color_parameter, select_visual):
        * xselect.c (x_clipboard_manager_error_1)
        (x_clipboard_manager_save_all):
        * xterm.c (x_term_init): Use build_local_string.

        Avoid more integer overflows on string size calculations.
        * category.c (Fmake_category_set):
        * xdisp.c (get_overlay_arrow_glyph_row):
        * w32font.c (intern_font_name): Prefer ptrdiff_t to int.

2014-09-15  Eli Zaretskii  <eliz@gnu.org>

        * sound.c [WINDOWSNT]: Include w32common.h and mbstring.h.
        (SOUND_WARNING) [WINDOWSNT]: Include in do..while and improve the
        error message format.  Use message_with_string to have non-ASCII
        file names properly displayed.
        (do_play_sound) [WINDOWSNT]: Use Unicode APIs to play sound files
        when w32-unicode-filenames is non-nil, but not on Windows 9X,
        where these APIs are not available even in UNICOWS.DLL.
        Improve the format of error messages and include the file name in them
        where appropriate.
        (Fplay_sound_internal) [WINDOWSNT]: Make the MS-Windows branch
        call play-sound-functions, per documentation.

        * w32.c (w32_get_long_filename, w32_get_short_filename):
        Constify the input file name arguments.

        * w32.h (w32_get_long_filename, w32_get_short_filename):
        Update prototypes.

2014-09-15  Dmitry Antipov  <dmantipov@yandex.ru>

        If USE_LOCAL_ALLOCATORS, allocate some Lisp objects on stack.
        * lisp.h (local_cons, local_list1, local_list2, local_list3)
        [USE_LOCAL_ALLOCATORS]: New macros.
        [!USE_LOCAL_ALLOCATORS]: Fall back to regular functions.
        (build_local_string): Avoid argument name expansion clash with
        make_local_string.
        * alloc.c (toplevel)
        [USE_LOCAL_ALLOCATORS && GC_MARK_STACK != GC_MAKE_GCPROS_NOOPS]:
        Preprocessor guard to avoid impossible configuration.
        * charset.c (Ffind_charset_region, Ffind_charset_string):
        Use make_local_vector.
        * lread.c (read1, substitute_object_recurse): Use scoped_cons.
        * textprop.c (Fput_text_property, Fadd_face_text_property):
        Use scoped_list2.
        (copy_text_properties): Use local_cons and local_list3.
        * chartab.c (uniprop_table):
        * data.c (wrong_choice, wrong_range):
        * doc.c (get_doc_string):
        * editfns.c (format2):
        * fileio.c (Fexpand_file_name, auto_save_error):
        * fns.c (Fyes_or_no_p):
        * font.c (font_parse_xlfd, font_parse_family_registry, font_add_log):
        * fontset.c (Fset_fontset_font):
        * keyboard.c (echo_add_key, echo_dash, parse_menu_item)
        (read_char_minibuf_menu_prompt):
        * keymap.c (silly_event_symbol_error, describe_vector):
        * menu.c (single_menu_item):
        * minibuf.c (Fread_buffer):
        * process.c (status_message, Fformat_network_address)
        (server_accept_connection): Use make_local_string and
        build_local_string.  Prefer compound literals where appropriate.

2014-09-15  Daniel Colascione  <dancol@dancol.org>

        * fns.c (Fsort): Tweak sort docstring.

2014-09-15  Eli Zaretskii  <eliz@gnu.org>

        * w32.c (fcntl): Support O_NONBLOCK fcntl on the write side of pipes.
        (sys_write): When a write to a non-blocking pipe returns ENOSPC,
        set errno to EAGAIN instead, to allow the caller to retry the
        write after some waiting.  Fixes deadlocks when Emacs exchanges a
        lot of data through the pipe.  (Bug#18420)

        * sound.c (Fplay_sound_internal): Encode the sound file name in
        the ANSI codepage.  Expand it against data-directory, as per docs,
        not against the current directory.  No need to make a local copy
        of the file name; pass the encoded file name directly to
        do_play_sound.  (Bug#18463)

        * w32.c (ansi_encode_filename): If w32_get_short_filename returns
        NULL, and the file name is not encodable in ANSI codepage, return
        the string with "?" replacement characters, which will fail the
        caller.  This avoids returning a random value in that case.

2014-09-15  Martin Rudalics  <rudalics@gmx.at>

        * window.c (Fresize_mini_window_internal): Set w->total_lines
        from w->pixel_height (Bug#18422).

2014-09-15  Jan Djärv  <jan.h.d@swipnet.se>

        * nsterm.m (updateFrameSize:, initFrameFromEmacs:)
        (toggleFullScreen:): Take frame_resize_pixelwise into account when
        setting resize increments (Bug#18435).

2014-09-15  Eli Zaretskii  <eliz@gnu.org>

        * xdisp.c (pos_visible_p): Properly save and restore the iterator
        state around the call to line_bottom, since it can move the
        iterator to another screen line.  This fixes off-by-one errors in
        the reported row in some rare cases.

2014-09-14  Jan Djärv  <jan.h.d@swipnet.se>

        * callproc.c (init_callproc): Fix bug introduced at
        2014-09-07 (Bug#18474).

2014-09-13  Dmitry Antipov  <dmantipov@yandex.ru>

        Prefer ptrdiff_t to int and avoid integer overflows.
        * fileio.c (make_temp_name):
        * font.c (font_parse_family_registry): Avoid integer
        overflow on string size calculation.
        * data.c (Faset): Likewise for byte index.

2014-09-12  Detlev Zundel  <dzu@member.fsf.org>

        * buffer.c (syms_of_buffer): DEFSYM Qchoice (Bug#18337).

2014-09-11  Dmitry Antipov  <dmantipov@yandex.ru>

        * lisp.h (make_local_string): Nitpick indent.
        * print.c (Fprin1_to_string): Remove unused GCPROs.

        More debugging aids around GCPROs.
        * lisp.h (struct gcpro) [DEBUG_GCPRO]: Add extra members.
        (GCPRO1, GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6, GCPRO7):
        Minor restyle.  If DEBUG_GCPRO, initialize extra fields.

        * lread.c (readevalloop_eager_expand_eval): Add GCPRO and fix
        bootstrap broken if GC_MARK_STACK == GC_USE_GCPROS_AS_BEFORE.

        Remove redundant GCPROs around Ffuncall and Fapply calls.
        This is safe because Ffuncall protects all of its arguments by itself.
        * charset.c (map_charset_for_dump): Remove redundant GCPRO.
        * eval.c (Fapply, apply1, call0, call1, call2, call3, call4, call5)
        (call6, call7): Likewise.  Use compound literals where applicable.
        (run_hook_with_args_2): Use compound literal.

2014-09-11  Paul Eggert  <eggert@cs.ucla.edu>

        Pacify --enable-gcc-warnings when no window system is used.
        These warnings found that subscript error, so they seem worthwhile.
        * composite.c (char_composable_p): Simplify a bit.
        * frame.c (x_set_frame_parameters): Add an IF_LINT.
        * frame.c (x_set_horizontal_scroll_bars, x_set_scroll_bar_height):
        * frame.h (FRAME_HAS_HORIZONTAL_SCROLL_BARS):
        * window.c (set_window_scroll_bars):
        Use USE_HORIZONTAL_SCROLL_BARS for simplicity.
        * frame.h [! USE_HORIZONTAL_SCROLL_BARS]:
        Ignore -Wsuggest-attribute=const.
        * window.h (USE_HORIZONTAL_SCROLL_BARS): New macro.
        (WINDOW_HAS_HORIZONTAL_SCROLL_BAR): Use it.

2014-09-10  Paul Eggert  <eggert@penguin.cs.ucla.edu>

        * charset.c (Fget_unused_iso_final_char): Fix subscript error.
        Use check_iso_charset_parameter instead of doing the checks by hand.
        (check_iso_charset_parameter): Move up.  Check parameters a bit
        more carefully, and return true for 96-char sets.  All callers changed.

2014-09-10  Paul Eggert  <eggert@cs.ucla.edu>

        Simplify lisp.h by removing the __COUNTER__ business.
        Problem reported by Dmitry Antipov in:
        http://lists.gnu.org/archive/html/emacs-devel/2014-09/msg00220.html
        * lisp.h (make_local_vector, make_local_string)
        (build_local_string): Simplify by not bothering with __COUNTER__.
        The __COUNTER__ business wasn't working properly, and was needed
        only for hypothetical future expansion anyway.

2014-09-10  Alp Aker  <alp.tekin.aker@gmail.com>

        * nsterm.m (ns_draw_fringe_bitmap): Use the same logic as other
        terms to determine bitmap color.  (Bug#18437)

2014-09-10  Eli Zaretskii  <eliz@gnu.org>

        * w32.c (sys_write): Use SAFE_NALLOCA for the NL -> CRLF
        translation buffer.

2014-09-10  Paul Eggert  <eggert@cs.ucla.edu>

        * xterm.c (handle_one_xevent): Add braces to pacify gcc -Wall.

2014-09-10  Jan Djärv  <jan.h.d@swipnet.se>

        * xterm.c (handle_one_xevent): Detect iconified by looking at
        _NET_WM_STATE_HIDDEN.

2014-09-10  Paul Eggert  <eggert@cs.ucla.edu>

        * lisp.h (DEFINE_GDB_SYMBOL_ENUM): Remove.
        These can generate a constant with the correct value but the wrong
        width, which doesn't work as a printf argument.  All uses removed.
        Problem reported by Dmitry Antipov in:
        http://lists.gnu.org/archive/html/emacs-devel/2014-09/msg00213.html
        (ENUMABLE): Remove; no longer needed.
        (ARRAY_MARK_FLAG_val, PSEUDOVECTOR_FLAG_val, VALMASK_val):
        Remove; no longer needed because of the above change.
        Each definiens moved to the only use.

        Improve the experimental local and scoped allocation.
        * alloc.c (local_string_init, local_vector_init):
        New functions, defined if USE_LOCAL_ALLOCATORS.
        Mostly, these are moved here from lisp.h, as it's not
        clear it's worth making them inline.
        * lisp.h (USE_STACK_LISP_OBJECTS): Default to false.
        (GCALIGNED): Depend on HAVE_STRUCT_ATTRIBUTE_ALIGNED and
        USE_STACK_LISP_OBJECTS, not on a laundry list.
        (local_string_init, local_vector_init): New decls.
        (union Aligned_Cons): New type.
        (scoped_cons): Use it.  Give up on the char trick, as it's a too
        much of a maintenance hassle; if someone wants this speedup
        they'll just need to convince their compiler to align properly.
        Conversely, use the speedup if struct Lisp_Cons happens to
        be aligned even without a directive.  Better yet, help it along
        by using union Aligned_Cons rather than struct Lisp_Cons.
        (pointer_valid_for_lisp_object): Remove.  This check is not
        necessary, since make_lisp_ptr is already doing it.  All uses removed.
        (local_vector_init, local_string_init): Move to alloc.c.
        (build_local_vector): Remove this awkward macro, replacing with ...
        (make_local_vector): New macro, which acts more like a function.
        Use statement expressions and use __COUNTER__ to avoid macro
        capture.  Fall back on functions if these features are not supported.
        (build_local_string, make_local_string): Likewise.

2014-09-09  Dmitry Antipov  <dmantipov@yandex.ru>

        * xterm.c (x_term_init): Consolidate duplicated code.
        [USE_LUCID]: Revert 2014-04-02 change (Bug#18403).  Add comment.
        (x_delete_terminal): Do not close X connection fd (Bug#18403).
        Add eassert and mark dpyinfo as dead only if it was alive.

        Add macros to allocate temporary Lisp objects with alloca.
        Respect MAX_ALLOCA and fall back to regular GC for large objects.
        * character.h (parse_str_as_multibyte): Move prototype to ...
        * lisp.h (parse_str_as_multibyte): ... here.
        (struct Lisp_Cons): Add GCALIGNED attribute if supported.
        (scoped_cons, scoped_list2, build_local_vector, build_local_string):
        New macros.
        (scoped_cons_init, pointer_valid_for_lisp_object, local_vector_init)
        (local_string_init): New functions.
        * alloc.c (verify_alloca) [ENABLE_CHECKING]: New function.
        (init_alloc_once): Call it.

        Cleanup last change and make all new stuff conditional.
        * lisp.h (build_local_string): Rename to ...
        (make_local_string): ... this macro.
        (build_local_string, scoped_list1, scoped_list3): New macros.
        (toplevel) [USE_STACK_LISP_OBJECTS]: Define all new macros
        and functions as such, use regular fallbacks otherwise.
        * alloc.c (verify_alloca) [USE_STACK_LISP_OBJECTS]: Define
        conditionally.

2014-09-08  Eli Zaretskii  <eliz@gnu.org>

        * dispnew.c (prepare_desired_row): When MODE_LINE_P is zero,
        always make sure the marginal areas of the row are in sync with
        what the window wants.  (Bug#18419)

        * data.c (set_internal): Use assq_no_quit, not Fassq, to find an
        existing binding of a variable, to avoid silently aborting
        commands that use specbind.  (Bug#18331)

2014-09-07  Paul Eggert  <eggert@cs.ucla.edu>

        Fix bug uncovered by changing alloca to auto buffer (Bug#18410).
        * coding.c (growable_destination): New function.
        (produce_chars): Use it for sanity checks.  Do not fiddle with
        dst_end if the source and destination are both nil, as it's
        the caller's responsibility to avoid overlap.
        * keyboard.c (read_decoded_event_from_main_queue):
        The destination must be MAX_MULTIBYTE_LENGTH times the max source
        length, not 4 times, to prevent decode_coding_c_string from trying
        to reallocate a destination.  This removes the need for the FIXME.

        * callproc.c (exec_failed) [DOS_NT]: Define a dummy.
        All callers simplified.  Add a comment about exec_failed, vfork,
        and alloca.

        Adjust drag-and-drop fix when window is above top (Bug#18303).
        * xselect.c (x_fill_property_data): Don't let sign bit of negative
        XCDR bleed into XCAR's encoded value.  Improve checks for
        out-of-range data while we're at it.

2014-09-07  Jan Djärv  <jan.h.d@swipnet.se>

        * xselect.c (x_fill_property_data): Handle negative XCDR when data
        is CONSP (Bug#18303).

2014-09-07  Eli Zaretskii  <eliz@gnu.org>

        * callproc.c (child_setup) [WINDOWSNT]: Don't call exec_failed if
        'alloca' gets passed arguments larger than MAX_ALLOCA.

        * font.c (MAX): Define if not defined elsewhere.

2014-09-07  Paul Eggert  <eggert@cs.ucla.edu>

        * keyboard.c (read_decoded_event_from_main_queue): Reinstitute alloca
        here for destination buffer, to work around what appears to be a
        bug in decode_coding_c_string when the source and destination are
        both C strings.

        Use SAFE_ALLOCA etc. to avoid unbounded stack allocation (Bug#18410).
        This follows up on the recent thread in emacs-devel on alloca; see:
        http://lists.gnu.org/archive/html/emacs-devel/2014-09/msg00042.html
        This patch also cleans up alloca-related glitches noted while
        examining the code looking for unbounded alloca.
        * alloc.c (listn):
        * callproc.c (init_callproc):
        Rewrite to avoid need for alloca.

        * xfaces.c (face_at_buffer_position):
        * xmenu.c (x_menu_show):
        Use SAFE_ALLOCA etc. instead of plain alloca, since the
        allocation size isn't bounded.
        * callint.c (Fcall_interactively): Redo memory_full check
        so that it can be done at compile-time on some platforms.

        (get_translation_table): Use it.
        * callproc.c (call_process): Use SAFE_NALLOCA instead of

        * xdisp.c (load_overlay_strings, dump_glyph_row):

        * ftfont.c: Include <c-strcase.h>.
        (matching_prefix): New function.
        (get_adstyle_property): Use it, to avoid need for alloca.
        * keyboard.c (echo_add_key):
        * keymap.c (describe_map): Use ptrdiff_t, not int.
        * keyboard.c (echo_add_key): Prefer sizeof to strlen.

        when counting bytes.
        * lisp.h (xlispstrdupa): Remove, replacing with ...
        (SAFE_ALLOCA_STRING): ... new macro with different API.
        This fixes a portability problem, namely, alloca result
        passed to another function.  All uses changed.
        (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Check for MAX_ALLOCA,
        not MAX_ALLOCA - 1.
        * regex.c (REGEX_USE_SAFE_ALLOCA, REGEX_SAFE_FREE)
        (REGEX_ALLOCATE): New macros.

2014-09-03  Eli Zaretskii  <eliz@gnu.org>

        * xdisp.c (display_and_set_cursor): Call erase_phys_cursor also
        when HPOS is negative, for the benefit of R2L glyph rows whose
        newline overflows into the fringe.

2014-09-03  Ken Brown  <kbrown@cornell.edu>

        to strlen and strcat.
        * callproc.c (egetenv_internal): Add arg and rename from egetenv ...

        Clean up extern decls a bit.
        * bytecode.c: Include blockinput.h and keyboard.h rather
        than rolling their APIs by hand.
        * emacs.c: Include regex.h and rely on its and lisp.h's API
        rather than rolling them by hand.
        * lastfile.c: Include lisp.h, to check this file's API.

2014-08-31  Eli Zaretskii  <eliz@gnu.org>

        * xdisp.c (get_glyph_string_clip_rects): Don't let the width of a
        clipping rectangle become negative (i.e. large positive, since
        it's an unsigned data type).  This can happen in R2L hscrolled
        glyph rows, and caused us to draw the cursor glyph on the fringe.
        For the details, see
        http://lists.gnu.org/archive/html/emacs-devel/2014-08/msg00543.html.

2014-08-31  Ken Brown  <kbrown@cornell.edu>

        * gmalloc.c: Don't include <stdlib.h>.  Declare system malloc and
        friends before defining hybrid_malloc and friends if HYBRID_MALLOC
        is defined.  (Bug#18368)

2014-08-30  Paul Eggert  <eggert@cs.ucla.edu>

        Vector-sorting fixes (Bug#18361).
        It's not safe to call qsort or qsort_r, since they have undefined
        behavior if the user-specified predicate is not a total order.
        Also, watch out for garbage-collection while sorting vectors.
        * fns.c: Include <vla.h>.
        (sort_vector_predicate) [!HAVE_QSORT_R]: Remove.
        (sort_vector_compare): Remove, replacing with ....
        (inorder, merge_vectors, sort_vector_inplace, sort_vector_copy):
        ... these new functions.
        (sort_vector): Rewrite to use the new functions.
        GCPRO locals, since the predicate can invoke the GC.
        Since it's in-place return void; caller changed.
        (merge): Use 'inorder', for clarity.

        * sysdep.c (str_collate): Clear errno just before wcscoll(_l).
        One can't hoist this out of the 'if', because intervening calls to
        newlocale, twolower, etc. can change errno.

2014-08-30  Eli Zaretskii  <eliz@gnu.org>

        * sysdep.c (str_collate) [__STDC_ISO_10646__]: Improve the
        wording of the error messages.
        (str_collate) [WINDOWSNT]: Signal an error if w32_compare_strings
        sets errno.

        * w32proc.c (get_lcid_callback): Accept locale specifications
        without the country part, as in "enu" vs "enu_USA".
        (w32_compare_strings): Signal an error if a locale was specified,
        but couldn't be translated into a valid LCID.

2014-08-29  Michael Albinus  <michael.albinus@gmx.de>

        * sysdep.c (str_collate) [__STDC_ISO_10646__]: Move up setting errno.

2014-08-29  Paul Eggert  <eggert@cs.ucla.edu>

        * sysdep.c (str_collate) [__STDC_ISO_10646__]: Do not look at
        errno after towlower_l.  errno's value is not specified after
        towlower_l.  Instead, assume that towlower_l returns its argument
        on failure, which is portable in practice.

2014-08-29  Eli Zaretskii  <eliz@gnu.org>

        * fns.c (Fstring_collate_lessp, Fstring_collate_equalp): Doc fix.

        * w32proc.c (w32_compare_strings): Accept additional argument
        IGNORE_CASE.  Set up the flags for CompareStringW to ignore case
        if requested.  If w32-collate-ignore-punctuation is non-nil, add
        NORM_IGNORESYMBOLS to the flags.
        (LINGUISTIC_IGNORECASE): Define if not already defined.
        (syms_of_ntproc) <Vw32_collate_ignore_punctuation>: New variable.

        * sysdep.c (str_collate) [WINDOWSNT]: Adapt to the interface
        change.

2014-08-29  Michael Albinus  <michael.albinus@gmx.de>

        * sysdep.c (LC_CTYPE, LC_CTYPE_MASK, towlower_l):
        Define substitutes for platforms that lack them.
        (str_collate): Add arguments locale and ignore_case.

        * fns.c (Fstring_collate_lessp, Fstring_collate_equalp):
        Add optional arguments LOCALE and IGNORE-CASE.

        * lisp.h (str_collate): Adapt argument list.

2014-08-29  Dmitry Antipov  <dmantipov@yandex.ru>

        Add vectors support to Fsort.
        * fns.c (sort_vector, sort_vector_compare): New functions.
        (sort_list): Likewise, refactored out of ...
        (Fsort): ... adjusted user.  Mention vectors in docstring.
        (sort_vector_predicate) [!HAVE_QSORT_R]: New variable.
        * alloc.c (make_save_int_obj): New function.
        * lisp.h (enum Lisp_Save_Type): New member SAVE_TYPE_INT_OBJ.
        (make_save_int_obj): Add prototype.

        Fix last change to support Darwin/OSX and FreeBSD (Bug#18354).
        * sysdep.c (sort_vector_compare) [DARWIN_OS || __FreeBSD__]:
        Conditionally define to match system's qsort_r signature.
        (sort_vector) [DARWIN_OS || __FreeBSD__]: Likewise in call to qsort_r.

2014-08-28  Ken Brown  <kbrown@cornell.edu>

        Add support for HYBRID_MALLOC, allowing the use of gmalloc before
        dumping and the system malloc after dumping.  (Bug#18222)

        * conf_post.h (malloc, realloc, calloc, free) [HYBRID_MALLOC]:
        Define as macros, expanding to hybrid_malloc, etc.
        (HYBRID_GET_CURRENT_DIR_NAME): New macro.
        (get_current_dir_name) [HYBRID_GET_CURRENT_DIR_NAME]: Define as
        macro.
        * gmalloc.c: Set up the infrastructure for HYBRID_MALLOC, with a
        full implementation on Cygwin.  Remove Cygwin-specific code that
        is no longer needed.

        (hybrid_aligned_alloc) [HYBRID_MALLOC && (HAVE_ALIGNED_ALLOC ||
        HAVE_POSIX_MEMALIGN)]: New functions.
        * alloc.c (aligned_alloc) [HYBRID_MALLOC && (ALIGNED_ALLOC ||
        HAVE_POSIX_MEMALIGN)]: Define as macro expanding to
        hybrid_aligned_alloc; declare.
        (USE_ALIGNED_ALLOC) [HYBRID_MALLOC && (ALIGNED_ALLOC ||
        HAVE_POSIX_MEMALIGN)]: Define.
        (refill_memory_reserve) [HYBRID_MALLOC]: Do nothing.
        * sysdep.c (get_current_dir_name) [HYBRID_GET_CURRENT_DIR_NAME]:
        Define as macro, expanding to gget_current_dir_name, and define
        the latter.
        * emacs.c (main) [HYBRID_MALLOC]: Don't call memory_warnings() or
        malloc_enable_thread().  Don't initialize malloc.
        * lisp.h (NONPOINTER_BITS) [CYGWIN]: Define (because GNU_MALLOC is
        no longer defined on Cygwin).
        (refill_memory_reserve) [HYBRID_MALLOC]: Don't declare.
        * sheap.c (bss_sbrk_buffer_end): New variable.

2014-08-28  Martin Rudalics  <rudalics@gmx.at>

        * w32term.c (w32_horizontal_scroll_bar_handle_click):
        In `event->y' return entire range (the size of the scroll bar minus
        that of the thumb).
        * xterm.c (xm_scroll_callback, xaw_jump_callback): In `whole'
        return entire range (the scaled size of the scroll bar minus
        that of the slider).  In `portion' return the scaled position of
        the slider.
        (xaw_jump_callback): Restore part of code for vertical scroll
        bar broken in change from 2014-07-27.
        (xaw_scroll_callback): Provide incremental scrolling with
        horizontal scroll bars.

2014-08-28  Eli Zaretskii  <eliz@gnu.org>

        * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Don't define.

        * indent.c (Fvertical_motion): Fix vertical motion up through a
        display property after a newline.  (Bug#18276)

        * xdisp.c (display_line): Don't assume that the call to
        reseat_at_next_visible_line_start ends up at a character
        immediately following the newline on the previous line.
        Avoids setting the ends_at_zv_p flag on screen lines that are not at or
        beyond ZV, which causes infloop in redisplay.  For the details, see
        http://lists.gnu.org/archive/html/emacs-devel/2014-08/msg00368.html.

        * dispnew.c (buffer_posn_from_coords): Fix mirroring of X
        coordinate for hscrolled R2L screen lines.  (Bug#18277)

2014-08-28  Paul Eggert  <eggert@cs.ucla.edu>

        * sysdep.c (LC_COLLATE, LC_COLLATE_MASK): Give individual defaults

2014-08-27  Paul Eggert  <eggert@cs.ucla.edu>

        Improve robustness of new string-collation code (Bug#18051).
        * sysdep.c (LC_COLLATE, LC_COLLATE_MASK, freelocale, locale_t)
        (newlocale, wcscoll_l): Define substitutes for platforms that
        lack them, so as to simplify the mainline code.
        (str_collate): Simplify the code by assuming the above definitions.
        Use wcscoll_l, not uselocale, as uselocale is too fragile.
        For example, the old version left the Emacs in the wrong locale if
        wcscoll reported an error.  Use 'int', not ptrdiff_t, for the int
        result.  Report an error if newlocale fails.

2014-08-27  Michael Albinus  <michael.albinus@gmx.de>

        * lisp.h (str_collate):
        * sysdep.c (str_collate): Return int.

        to stack boundary, and handle fatal signal as usual if not.
        (init_sigsegv): Adjust accordingly.
        * keyboard.c (Vtop_level_message): Rename to
        Vinternal__top_level_message, as suggested by Stefan Monnier in
        http://lists.gnu.org/archive/html/emacs-devel/2014-08/msg00493.html
        All related users changed.

        (regular_top_level_message): New variable.
        (command_loop) [HAVE_STACK_OVERFLOW_HANDLING]: Handle non-local

        [WINDOWSNT]: Call str_collate on MS-Windows.

2014-08-25  Dmitry Antipov  <dmantipov@yandex.ru>

        One more minor cleanup of font subsystem.
        * font.h (struct font_driver): Convert text_extents to
        return void because returned value is never actually used.
        * macfont.m (macfont_text_extents):
        * w32font.c (w32font_text_extents):
        * xftfont.c (xftfont_text_extents): Adjust to return void

        * ftfont.c (ftfont_text_extents):
        * xfont.c (xfont_text_extents): Likewise.  Avoid redundant memset.

2014-08-25  Paul Eggert  <eggert@cs.ucla.edu>

        Minor cleanups of str_collate fix (Bug#18051).

        * lisp.h (str_collate): ... to here.
        * sysdep.c (str_collate): Prune away some of the forest of ifdefs.
        Remove unnecessary casts.  Use SAFE_NALLOCA to avoid
        potential problems with integer overflow.  Don't assume
        setlocale succeeds.  Remove unnecessary test before restoring
        locale via setlocale, and free the copied setlocale string
        when done with it.

2014-08-24  Michael Albinus  <michael.albinus@gmx.de>

        * fns.c (Fstring_collate_lessp, Fstring_collate_equalp): New DEFUNs.

2014-08-11  Glenn Morris  <rgm@gnu.org>

        * fileio.c: Revert 2013-01-31 change, which chose coding system for
        writing before backing up, since it causes a more serious problem
        than the one it solves.  (Closes Bug#18141, reopens Bug#13522.)
        (choose_write_coding_system): No longer callable from Lisp.
        Move last piece back here from Fwrite_region.

        inhibit-quit to t and pass 2 args to safe_run_hook_funcall.  See
        <http://lists.gnu.org/archive/html/emacs-devel/2014-08/msg00077.html>.
        (safe_run_hook_funcall): Adjust accordingly.

2014-08-03  Paul Eggert  <eggert@cs.ucla.edu>

        Don't let big frames overrun the stack.
        * dispnew.c (mirrored_line_dance, mirror_line_dance, scrolling):
        Use SAFE_NALLOCA, not alloca.

        Fix bug with clang + directory_files_internal + GC (Bug#16986).
        * dired.c (directory_files_internal): Use a volatile variable
        to prevent the compiler from optimizing away all copies of a local.
        I wonder how many other GC-related bugs like this lurk elsewhere?

        Avoid 100% CPU utilization on ssh session exit (Bug#17691).
        * xterm.h (struct x_display_info): New member 'connection'.
        * xterm.c (x_term_init, x_delete_terminal): Set and use it,
        so that x_delete_terminal has a file descriptor to pass to

        Don't mishandle year-9999 dates (Bug#18176).
        * editfns.c (decode_time_components): Store an invalid timespec
        on overflow, instead of returning false, so that the caller can
        distinguish overflow from other errors.
        (lisp_time_argument, lisp_seconds_argument): If the time is out
        of range, signal a time overflow instead of an invalid time spec.
        * keyboard.c (decode_timer): Treat time overflow like other

        See http://lists.gnu.org/archive/html/emacs-devel/2014-07/msg00476.html
        for the details.
        * xdisp.c (extend_face_to_end_of_line): If the last glyph of an
        R2L row is visible only partially, give the row a negative x
        offset.
        (display_line): Fix the calculation of the glyph whose pixel width
        is used to decide whether the last produced glyph fits on the
        line.  When the last glyph fits only partially, give the row a
        negative x offset.

        Fix hscroll of R2L lines that begin with a TAB or another wide glyph.
        * xdisp.c (append_stretch_glyph): In a R2L glyph row, decrease the
        pixel width of the first glyph that is hscrolled from display.
        (display_line): In R2L glyph rows, don't give a negative offset to
        row->x when the first glyph begins before first_visible_x.

        * xdisp.c (display_line): If called with iterator set up to write
        to a marginal area, delay the call to handle_line_prefix until we
        switch back to the text area.  (Bug#18035)

        * .gdbinit (xwindow): The members total_cols, total_lines,
        left_col, and top_line are C integers (and has been so for the
        last 1.5 years).

2014-08-01  Andreas Schwab  <schwab@suse.de>

        * macros.c (Fstart_kbd_macro): Initialize kbd_macro_ptr and
        kbd_macro_end together with kbd_macro_buffer.  (Bug#18140)

2014-08-01  Dmitry Antipov  <dmantipov@yandex.ru>

        * atimer.c (toplevel) [HAVE_TIMERFD]: Include errno.h.
        (timerfd_callback): Ignore weird events with no data.  Add tight
        assertions and comments.
        (init_atimer) [HAVE_TIMERFD]: Add environment variable to optionally
        disable timerfd-based timer.  Use TFD_NONBLOCK for timer descriptor.

2014-08-01  Paul Eggert  <eggert@cs.ucla.edu>

        * frame.c (x_set_frame_parameters): Fix typo in previous patch.

        Simplify timerfd configuration and fix some minor glitches.
        * atimer.c (TIMERFD_CREATE_FLAGS): Remove; we now assume TFD_CLOEXEC.
        (alarm_timer, alarm_timer_ok, set_alarm, init_atimer):
        Fall back on timer_create if timerfd_create fails at runtime.
        (resolution) [HAVE_CLOCK_GETRES]: Remove; we now rely on the
        kernel primitives to do resolution.  All uses removed.
        (timerfd) [!HAVE_TIMERFD]: Define to be -1, for convenience.
        (turn_on_atimers): Clear timer_create-based timers too,
        for consistency.

        * frame.c (x_set_frame_parameters): Don't use uninitialized locals.
        Without this change, the code can access the local variable 'width'
        even when it has not been initialized, and likewise for 'height';
        in either case this leads to undefined behavior.

2014-07-30  Dmitry Antipov  <dmantipov@yandex.ru>

        * xrdb.c (x_load_resources) [USE_MOTIF]: Although not strictly
        necessary, put horizontal scroll bar resources as well.  See

        FRAME_X_WINDOW when calling x_set_window_size (Bug#18138).

2014-07-28  Martin Rudalics  <rudalics@gmx.at>

        * frame.c (x_set_frame_parameters): Revert part of 2014-07-24
        change that added the top margin height to the requested height
        and revert (undocumented) part of 2014-07-28 change that changed
        the logic of whether a size change occurred.

2014-07-28  Eli Zaretskii  <eliz@gnu.org>

        * .gdbinit (xwindow): The members total_cols, total_lines,
        left_col, and top_line are C integers (and has been so for the
        last 1.5 years).

        * .gdbinit (xsubchartable): The members 'depth' and 'min_char' are
        now C integers.

        system timer resolution.
        (set_alarm) [HAVE_TIMERFD]: Use timerfd_settime.
        (timerfd_callback) [HAVE_TIMERFD]: New function.
        (atimer_result, debug_timer_callback, Fdebug_timer_check)
        [ENABLE_CHECKING]: New function for the sake of automated tests.
        (init_atimer) [HAVE_TIMERFD]: Setup timerfd.
        [HAVE_CLOCK_GETRES]: Likewise for system timer resolution.
        [ENABLE_CHECKING]: Defsubr test function.
        * atimer.h (timerfd_callback) [HAVE_TIMERFD]: Add prototype.
        * lisp.h (add_timer_wait_descriptor) [HAVE_TIMERFD]: Likewise.
        * process.c (add_timer_wait_descriptor) [HAVE_TIMERFD]: New function.

        Revert previous change.
        There is certainly nothing wrong with writing code like 'lo <= i
        && i <= hi', even if LO happens to a constant.  There isn't even
        anything wrong in general with writing 'a <= b' if A happens to
        be a constant.  At any rate stylistic changes shouldn't
        be done like this without discussion.

        extra padding and shrink struct coding_system by 56 bytes (x86_64).
        * coding.c (decode_coding_utf_8, decode_coding_utf_16)
        (decode_coding_emacs_mule, decode_coding_iso_2022, decode_coding_sjis)

        * xdisp.c (pos_visible_p): If CHARPOS is at beginning of window,
        and there is a display property at that position, don't call
        move_it_to to move to a position before window start.  (Bug#17942)
        Fix condition for finding CHARPOS by the first call to move_it_to.

        * xdisp.c (redisplay_window): If redisplay of a window ends up
        with point in a partially visible line at end of the window, make
        sure the amended position of point actually has smaller Y

        * window.c (window_scroll_pixel_based): When point ends up at the
        last fully visible line, don't let move_it_to stop at the left

        (imagemagick_load_image): Use int for pixel counts that can't
        exceed INT_MAX.  Avoid problem if PixelGetNextIteratorRow returns
        a row width greater than the image width (or greater than LONG_MAX!).

        * frame.c (do_switch_frame): When switching to another TTY frame,
        make sure FrameCols and FrameRows are in sync with the new frame's
        data.  (Bug#17875)

        error string where appropriate.  (Bug#17790)

        Change object marking routines to minimize stack usage.
        This change moves a few cold paths from mark_object to NO_INLINE
        functions and adjusts symbol marking loop.  According to GCC 4.8.2
        -Wstack-usage, this reduces mark_object's stack usage from 80 to
        48 bytes on a 64-bit system.  For a long byte-force-recompile runs,
        stack usage at the mark phase is reduced up to 28%.  Surprisingly,
        it also gains up to 3% in speed (with default '-O2 -g3' flags).
        * alloc.c (mark_compiled, mark_localized_symbol): New functions,
        refactored out from ...
        (mark_object): ... adjusted user.  Also mark symbols in a tight

        exit).

        Minimize cursor motion during TTY menu updates.
        * term.c (tty_menu_display): Don't position cursor here.
        Instead, pass the cursor coordinates to update_frame_with_menu.
        (tty_menu_activate): Send the hide cursor command only once in an
        iteration through the outer 'while' loop.

        * dispnew.c (update_frame_1): Accept an additional argument
        SET_CURSOR_P, and position the cursor at the end of the frame
        update only if that argument is non-zero.  All callers changed to
        provide the additional argument as non-zero, except for
        update_frame_with_menu.
        (update_frame_with_menu): Accept 2 additional arguments ROW and
        COL; if they are non-negative, instruct update_frame_1 not to
        position the cursor, and instead position it according to ROW and COL.

        * xterm.c (xg_scroll_callback): Remove position, for jump set portion
        to min(value, whole).

2014-06-02  Paul Eggert  <eggert@cs.ucla.edu>

        Bring back the changes to GDB-visible symbols, but only on AIX.
        And only if it's not pre-4.2 GCC.
        * lisp.h (ENUMABLE, DEFINE_GDB_SYMBOL_ENUM): New macros.
        (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Use them.
        (ARRAY_MARK_FLAG_val, PSEUDOVECTOR_FLAG_val, VALMASK_val):
        New macros.

2014-06-02  Eli Zaretskii  <eliz@gnu.org>

        * fileio.c (Finsert_file_contents): Call prepare_to_modify_buffer
        with PT, not GPT.  (Bug#16433)

        Revert last changes to GDB-visible symbols.
        * lisp.h (ENUMABLE, DEFINE_GDB_SYMBOL_ENUM): Delete macros.
        (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Don't use them.
        (ARRAY_MARK_FLAG_val, PSEUDOVECTOR_FLAG_val, VALMASK_val):
        Delete macros.

2014-06-02  Glenn Morris  <rgm@gnu.org>

        * cmds.c (Fself_insert_command): Allow zero repeat count.  (Bug#17649)

2014-06-02  Paul Eggert  <eggert@cs.ucla.edu>

        Fix port to 32-bit AIX with xlc (Bug#17598).
        * alloc.c (gdb_make_enums_visible): Remove FLOAT_TO_STRING_BUFSIZE.
        * conf_post.h (FLEXIBLE_ARRAY_MEMBER) [__IBMC__]: Don't define to empty.
        * lisp.h (FLOAT_TO_STRING_BUFSIZE): Make it a macro, instead of an enum,
        to work around a compiler bug in IBM xlc 12.1.

2014-06-02  Eli Zaretskii  <eliz@gnu.org>

        * xterm.c (x_update_window_end): Don't invalidate the entire
        mouse-highlight info, just signal frame_up_to_date_hook that mouse
        highlight needs to be redisplayed.  (Bug#17588)

2014-06-02  Paul Eggert  <eggert@cs.ucla.edu>

        Port the GDB-visible symbols to AIX.
        Without them, GDB doesn't work to debug Emacs, since the AIX linker
        optimizes away the relevant external symbols.  Use enums instead;
        this suffices for the AIX port, which is 32-bit-only anyway.
        * lisp.h (ENUMABLE, DEFINE_GDB_SYMBOL_ENUM): New macros.
        (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Use them.
        (ARRAY_MARK_FLAG_val, PSEUDOVECTOR_FLAG_val, VALMASK_val):
        New macros.

        Include sources used to create macuvs.h.
        * Makefile.in ($(srcdir)/macuvs.h): New rule.
        * macuvs.h: Use automatically-generated header.

2014-06-01  Paul Eggert  <eggert@cs.ucla.edu>

        Port signal-handling to DragonFly BSD (Bug#17646).
        * callproc.c, sysdep.c (block_child_signal, unblock_child_signal):
        Move implementations from callproc.c to sysdep.c.
        * process.h, syssignal.h (block_child_signal, unblock_child_signal):
        Move declarations from process.h to syssignal.h.

2014-06-01  Juanma Barranquero  <lekktu@gmail.com>

        (malloc_before_dump, realloc_after_dump, realloc_before_dump)
        (mmap_alloc, mmap_realloc): Check for errors more thoroughly and
        set errno where appropriate to emulate CRT functions.

2014-05-30  Dmitry Antipov  <dmantipov@yandex.ru>

        Debugging facility to check whether 'const char *' points to
        relocatable data of non-pure Lisp string.
        * alloc.c (maybe_lisp_pointer): New function, refactored out of ...
        (mark_maybe_pointer): ... adjusted user.

        * lisp.h (relocatable_string_data_p): Add prototype.
        * xdisp.c (message_with_string): If ENABLE_CHECKING, make sure
        the pointer to relocatable Lisp data is not used.

2014-05-30  Paul Eggert  <eggert@cs.ucla.edu>

        Don't let SIGINT handling block SIGCHLD indefinitely (Bug#17561).
        * atimer.c (block_atimers):
        * callproc.c (block_child_signal): Block SIGINT too;
        otherwise, its handler might now unblock signals that it shouldn't.
        * keyboard.c (read_char): Clear signal mask, since we may
        be in a SIGINT handler, and many signals may be masked.
        * keyboard.c (handle_interrupt):
        * sysdep.c (handle_arith_signal):
        Clear signal mask instead of just unblocking the signal that
        was received, since several signals may be blocked at this point.

2014-05-29  Eli Zaretskii  <eliz@gnu.org>

        * Makefile.in (TEMACS_POST_LINK): Remove target.
        (emacs$(EXEEXT)): Remove $(ADDSECTION) from prerequisites.
        (temacs$(EXEEXT)): Remove $(TEMACS_POST_LINK) from the recipe.

2014-05-29  Dmitry Antipov  <dmantipov@yandex.ru>

        * xmenu.c (xdialog_show): Remove prototype, rename to
        x_dialog_show, remove 2nd arg because it's always zero
        and simplify accordingly.
        (xw_popup_dialog): Adjust user.
        * w32menu.c (w32_dialog_show): Adjust prototype, remove
        2nd arg because it's always zero and simplify accordingly.

2014-05-29  Eli Zaretskii  <eliz@gnu.org>

        * w32heap.c (report_temacs_memory_usage): New function.

        * unexw32.c (unexec) [ENABLE_CHECKING]:
        Call report_temacs_memory_usage.

2014-05-29  Paul Eggert  <eggert@cs.ucla.edu>

        Don't substitute sigprocmask for pthread_sigmask (Bug#17561).
        * Makefile.in (LIB_PTHREAD_SIGMASK): Remove; all uses removed.

2014-05-29  Eli Zaretskii  <eliz@gnu.org>

        * buffer.c (init_buffer): Accept an argument 'initialized'.
        [USE_MMAP_FOR_BUFFERS]: If 'initialized' is non-zero, reset
        mmap_regions and mmap_fd, to avoid referencing stale data from the
        dump phase.  Add an assertion for buffer text of buffers created
        in temacs before this function is called.  (Bug#17622)
        (mmap_regions_1, mmap_fd_1): Remove unused variables.

        * lisp.h (init_buffer): Update prototype.

        * emacs.c (main): Pass 'initialized' as the argument to init_buffer.

2014-05-29  Dmitry Antipov  <dmantipov@yandex.ru>

        GC_MARK_STACK == GC_USE_GCPROS_AS_BEFORE.

2014-05-29  Paul Eggert  <eggert@cs.ucla.edu>

        * frame.c, frame.h (frame_char_to_pixel_position)
        (frame_set_mouse_position): Now static, and made private in
        frame.c rather than public in frame.h.

2014-05-28  Dmitry Antipov  <dmantipov@yandex.ru>

        Refactor mouse positioning stuff to avoid code duplication.
        * frame.h (frame_char_to_pixel_position): New function.

        * frame.c (Fset_mouse_pixel_position, Fset_mouse_position):
        Adjust users.
        * xterm.h, w32term.h ( x_set_mouse_position)
        (x_set_mouse_pixel_position): Remove prototypes.

2014-05-28  Dmitry Antipov  <dmantipov@yandex.ru>

        On X, always make pointer visible when deleting frame (Bug#17609).
        * frame.c (frame_make_pointer_visible, frame_make_pointer_invisible):
        Pass frame as arg.
        * frame.h (frame_make_pointer_visible, frame_make_pointer_invisible):
        Adjust prototypes.
        * cmds.c (Fself_insert_command): Use SELECTED_FRAME.
        * keyboard.c (gobble_input): If there is no terminal input error,
        make sure the pointer is visible for all frames on this terminal.
        * xterm.c (x_free_frame_resources): Enable pointer visibility if
        it was previously disabled.

2014-05-28  Stefan Monnier  <monnier@iro.umontreal.ca>

        (Qcall_interactively): Remove.
        (Ffuncall_interactively): New function.
        (Fcall_interactively): Use it.
        (syms_of_callint): Defsubr it.

2014-05-27  Stefan Monnier  <monnier@iro.umontreal.ca>

        * bytecode.c (FETCH) [BYTE_CODE_SAFE]: Check the bytecode wasn't
        relocated from under us.

2014-05-27  Fabrice Popineau  <fabrice.popineau@gmail.com>

        Use mmap(2) emulation for allocating buffer text on MS-Windows.
        * Makefile.in (C_HEAP_SWITCH): Get the predefined heap size from
        configure, not from HEAPSIZE.
        (ADDSECTION, MINGW_TEMACS_POST_LINK): Remove, no longer used.

        * lisp.h (NONPOINTER_BITS): Modify the condition to define to zero
        for MinGW, since it no longer uses gmalloc.

        * buffer.c: Do not define mmap allocations functions for Windows.
        Remove mmap_find which is unused. Remove mmap_set_vars which does
        nothing useful.
        [WINDOWSNT]: Include w32heap.h.
        (init_buffer): Always allocate new memory for buffers.

        * emacs.c: Remove mmap_set_vars calls.

        * image.c (free_image): Undef free for Windows because it is
        redirected to our private version.

        * unexw32.c (COPY_PROC_CHUNK): Use %p format for 64bits compatibility.
        (copy_executable_and_dump_data): Remove dumping the heap section.
        (unexec): Restore using_dynamic_heap after dumping.

        * w32heap.c (dumped_data_commit, malloc_after_dump)
        (malloc_before_dump, realloc_after_dump, realloc_before_dump)

        (mmap_free): New functions.

        * w32heap.h: Declare dumped_data and mmap_* function prototypes.

2014-05-27  Paul Eggert  <eggert@cs.ucla.edu>

        * image.c (imagemagick_load_image): Use MagickRealType for local
        'color_scale', instead of double, to avoid a GCC warning about
        double promotion.

        * xfns.c (Fx_window_property): Remove unused local.

        Don't kill already-reaped process (Bug#17561).
        * process.c (process_send_signal): Fix race condition where a
        subprocess was reaped by a signal handler between the check for
        liveness and calling 'kill', which meant that Emacs could in
        theory kill an innocent bystander process.  Do the fix by blocking
        SIGCHLD in a critical section that checks liveness before killing.

2014-05-26  Eli Zaretskii  <eliz@gnu.org>

        * w32.c (_ANONYMOUS_UNION, _ANONYMOUS_STRUCT): Define only if undefined.

        * nsterm.m (ns_init_events, ns_finish_events): New functions.
        (ns_read_socket, ns_select): Call ns_init_events, ns_finish_events.

        * nsfns.m (ns_do_applescript): Surround executeAndReturnError
        with calls to ns_init_events, ns_finish_events (Bug#17424).

2014-05-26  Eli Zaretskii  <eliz@gnu.org>

        * xdisp.c (move_it_in_display_line_to): Don't record wrap position
        if we are iterating over an object that generates glyphs for
        marginal areas.  (Bug#17585)

2014-05-26  Paul Eggert  <eggert@cs.ucla.edu>

        * xdisp.c (safe__call1, safe__eval): Now static.

2014-05-26  Eli Zaretskii  <eliz@gnu.org>

        * xdisp.c (safe__call): Accept va_list argument instead of '...'.
        (safe_call, safe__call1): Construct a va_list argument for safe_call.
        (safe_call1): Call safe_call instead of safe__call directly.

2014-05-26  Ken Brown  <kbrown@cornell.edu>

        * w32term.c (x_delete_display) [CYGWIN]: Don't free
        dpyinfo->w32_id_name, to make sure it doesn't get freed more than
        once.  (Bug#17510)

2014-05-26  Stefan Monnier  <monnier@iro.umontreal.ca>

        * xdisp.c: Bind inhibit-quit during pre-redisplay-function.
        (safe__call, safe__call1, safe__eval): New functions.
        (safe_call): Use it.
        (prepare_menu_bars): Use it for pre-redisplay-function (bug#17577).
        (display_mode_element): Same for `:eval'.

2014-05-26  Paul Eggert  <eggert@cs.ucla.edu>

        Fix port to 32-bit AIX (Bug#17540).
        * unexaix.c (copy_text_and_data): Don't add text_scnptr to ptr
        twice.  _text already includes this offset.
        (unrelocate_symbols): Don't cast 64-bit integer to pointer.

2014-05-26  Eli Zaretskii  <eliz@gnu.org>

        * xdisp.c (move_it_in_display_line_to): Avoid infinite recursion:
        when closest_pos is identical to to_charpos, don't recurse, since
        we already tried that, and failed.  (Bug#17539)

        * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: If we are
        unwinding when frame's faces were not initialized yet, increment
        the frame's image-cache reference count before calling
        x_free_frame_resources.  Don't dereference
        dpyinfo->terminal->image_cache if it is NULL.  (Bug#17524)

2014-05-25  Jan Djärv  <jan.h.d@swipnet.se>

        * nsfont.m (nsfont_draw): Simplify as arguments are adjusted in
        nsterm.m now.

        * nsterm.m (ns_draw_glyph_string): Move isComposite and end from
        macfont.m, call draw with adjusted arguments so font drivers
        don't need to do that.

        * macfont.m (macfont_draw): Merge changes from Macport.

2014-05-24  Eli Zaretskii  <eliz@gnu.org>

        * alloc.c (garbage_collect_1): New function, with all of the guts
        of Fgarbage_collect.
        (mark_stack): Accept an argument END and don't mark Lisp objects
        on the stack beyond the address given by END.  Calculation of END
        was moved to Fgarbage_collect.
        (Fgarbage_collect): Calculate the end address of the stack portion
        that needs to be examined by mark_stack, and pass that address to
        garbage_collect_1, which will pass it to mark_stack.
        See http://lists.gnu.org/archive/html/emacs-devel/2014-05/msg00270.html
        for more details about the underlying problems.  In particular,
        this avoids dumping Emacs with the large hash-table whose value is
        held in purify-flag for most of the time loadup.el runs.

2014-05-24  Jan Djärv  <jan.h.d@swipnet.se>

        * xfns.c (x_window_property_intern): New function (code from
        x_window_property).
        (Fx_window_property): Call x_window_property_intern.  If property
        not found and NILP (source) and outer window != inner window,
        check outer window for property (Bug#17537).

2014-05-22  Paul Eggert  <eggert@cs.ucla.edu>

        Supply malloc and alloc_size attributes for extern allocators.
        This documents the C API, and helps GCC generate a bit better code.
        * conf_post.h (ATTRIBUTE_MALLOC, ATTRIBUTE_ALLOC_SIZE)
        (ATTRIBUTE_MALLOC_SIZE): New macros.
        * gmalloc.c (malloc, realloc, calloc):

2014-05-19  Paul Eggert  <eggert@cs.ucla.edu>

        Allow any non-nil value to count as true in bool-vector.
        Likewise for xd_signature in dbusbind.c.
        This is more consistent with the usual practice in Emacs, which is
        that any non-nil value counts as true.
        * alloc.c (Fbool_vector): Don't require args to be t or nil.
        * dbusbind.c (xd_signature): Likewise, for booleans.
        * data.c, lisp.h (Qbooleanp):

        from the vector of matching entities (Bug#17486).

2014-05-17  Paul Eggert  <eggert@cs.ucla.edu>

        Assume C99 or later (Bug#17487).
        * bytecode.c (B__dummy__): Remove.
        * conf_post.h (bool_bf) [!NS_IMPL_GNUSTEP]: Use bool.

        * xterm.c (x_create_terminal): Adjust users.
        Avoid redundant NULL initializers and add comments.

2014-05-13  Paul Eggert  <eggert@cs.ucla.edu>

2014-04-30  Paul Eggert  <eggert@cs.ucla.edu>

        * term.c (tty_menu_activate): Don't assume row and col are initialized.
        GCC 4.9.0 warned about this, and I couldn't easily prove to my own

2014-04-30  Eli Zaretskii  <eliz@gnu.org>

        * term.c (tty_menu_display): Move the cursor to the active menu item.

        bits_word is typically a tad more efficient for mark bits than
        unsigned is, so use bits_word.  All uses changed.
        * lisp.h (BITS_PER_INT): Remove; no longer used.

        Avoid undefined behavior in signed left shift.

        * conf_post.h (ADDRESS_SANITIZER_WORKAROUND): Port to GCC 4.9.0
        and to clang 3.4, which have fixed the bug.  This should let us
        run a bit faster on these platforms when address sanitization is
        in effect.

2014-04-22  Paul Eggert  <eggert@cs.ucla.edu>

        Port to GCC 4.9.0 with --enable-gcc-warnings.

        paragraph-start cache before the newline cache.  (Bug#17269)

        Remove DATA_SEG_BITS.
        The DATA_SEG_BITS hack was needed for older 32 bit platforms.
        As a result of this change, Emacs won't work on IRIX 6.5 with IRIX
        cc, but that platform is so old that SGI itself stopped supporting
        it in December 2013.  If you still need Emacs on IRIX, please

        './configure --with-wide-int'.
        * alloc.c (gdb_make_enums_visible): Update to match lisp.h.

2014-04-12  Eli Zaretskii  <eliz@gnu.org>

        * xdisp.c (move_it_by_lines): If a large portion of buffer text is
        covered by a display string that ends in a newline, and that cases
        going back by DVPOS lines to hit the search limit, lift the limit
        and go back until DVPOS is reached.  (Bug#17244)

        * indent.c (Fvertical_motion): Handle correctly the case when the
        display string is preceded by an empty line.

        * w32.c (sys_umask) <WRITE_USER>: Remove redundant constant, and

2014-04-02  Martin Rudalics  <rudalics@gmx.at>

        * xterm.c (x_new_font): Don't calculate non-toolkit scrollbar
        width from font width (Bug#17163).

        * frame.c (x_set_frame_parameters): Calculate default values of
        new frame sizes only after all other frame parameters have been
        processed (Bug#17142).

2014-04-02  Ken Brown  <kbrown@cornell.edu>

        * conf_post.h (SYSTEM_PURESIZE_EXTRA) [CYGWIN]: Set to 10000.

        width accordingly when its x position is adjusted.  (Bug#17115)

2014-04-02  Dmitry Antipov  <dmantipov@yandex.ru>

        * font.c (font_list_entities): Do not add empty vector to font cache.
        (font_matching_entity): Likewise.  If matching entity is found, insert
        1-item vector with this entity instead of entity itself (Bug#17125).

        * xterm.c (x_term_init) [USE_LUCID]: Fix minor memory leak.

2014-04-01  Paul Eggert  <eggert@cs.ucla.edu>

        * fns.c (validate_subarray): Rename from validate_substring,
        since it works for vectors too.  New arg ARRAY.  Optimize for the
        non-nil case.  Instead of returning bool, throw an error if out of
        range, so that the caller needn't do that.  All uses changed.
        Report original values if out of range.
        (Fsubstring, Fsubstring_no_properties, secure_hash):
        Also optimize the case where FROM is 0 or TO is the size.

2014-03-31  Dmitry Antipov  <dmantipov@yandex.ru>

        * search.c (Freplace_match): Use make_specified_string.
        * xterm.c, w32term.c (x_set_glyph_string_gc): Use emacs_abort
        to catch bogus override face of glyph strings.
        * fns.c (Fsubstring, Fsubstring_no_properties, secure_hash):
        Move common substring range checking code to...

2014-03-30  Jan Djärv  <jan.h.d@swipnet.se>

        * nsterm.m (updateFrameSize:): If waiting for the tool bar and tool

        * nsterm.h (EmacsView): Add wait_for_tool_bar.

        * nsmenu.m (update_frame_tool_bar): Return early if view or toolbar
        is nil.  If waiting for toolbar to complete, force a redraw.

2014-03-28  Glenn Morris  <rgm@gnu.org>

        * emacs.c (emacs_version): Use PACKAGE_VERSION rather than VERSION.
        (emacs_bugreport): New variable.
        (usage_message): Use PACKAGE_BUGREPORT.
        (syms_of_emacs) <report-emacs-bug-address>: New variable.

        * emacs.c (syms_of_emacs) <system-configuration-features>: New var.

2014-03-27  Paul Eggert  <eggert@cs.ucla.edu>

        Port recent signal-related changes to FreeBSD.
        Problem reported by Herbert J. Skuhra.
        * lisp.h (block_tty_out_signal, unblock_tty_out_signal):
        Move decls from here ...
        * syssignal.h: ... to here, so that lisp.h doesn't depend on signal.h.

2014-03-27  YAMAMOTO Mitsuharu  <mituharu@math.s.chiba-u.ac.jp>

        * w32term.c (x_draw_image_glyph_string): Fix computation of height
        and width of image background when it is displayed with a 'box'
        face.  (Bug#17115)

2014-03-27  Paul Eggert  <eggert@penguin.cs.ucla.edu>

        More backward-compatible fix to char-equal core dump (Bug#17011).
        * editfns.c (Fchar_equal): In unibyte buffers, assume values in
        range 128-255 are raw bytes.  Suggested by Eli Zaretskii.

2014-03-27  Juanma Barranquero  <lekktu@gmail.com>

        * image.c (init_svg_functions): When loading SVG-related libraries,
        free already loaded libraries if the initialization fails.
        (rsvg_handle_set_size_callback): Remove declaration, unused.

2014-03-26  Paul Eggert  <eggert@cs.ucla.edu>

        Fix core dump in char-equal (Bug#17011).
        * editfns.c (Fchar_equal): Do not use MAKE_CHAR_MULTIBYTE in
        unibyte buffers, as we can't tell whether the characters are
        actually unibyte.

        * insdel.c (adjust_markers_for_delete): Remove unused local.

2014-03-26  Barry O'Reilly  <gundaetiapo@gmail.com>

        Have (MARKER . ADJUSTMENT) undo records always be immediately
        after their corresponding (TEXT . POS) record in undo list.
        (Bug#16818)
        * lisp.h (record-delete): New arg record_markers.
        (record_marker_adjustment): No longer needed outside undo.c.
        * insdel.c (adjust_markers_for_delete): Move calculation of marker
        adjustments to undo.c's record_marker_adjustments.  Note that
        fileio.c's decide_coding_unwind is another caller to
        adjust_markers_for_delete.  Because it has undo list bound to t,
        it does not rely on adjust_markers_for_delete to record marker
        adjustments.
        (del_range_2): Swap call to record_delete and
        adjust_markers_for_delete so as undo marker adjustments are
        recorded before current deletion's adjustments, as before.
        (adjust_after_replace):
        (replace_range): Pass value for new record_markers arg to
        delete_record.
        * undo.c (record_marker_adjustment): Rename to
        record_marker_adjustments and made static.
        (record_delete): Check record_markers arg and call
        record_marker_adjustments.
        (record_change): Pass value for new record_markers arg to
        delete_record.
        (record_point): at_boundary calculation no longer needs to account
        for marker adjustments.

2014-03-26  Martin Rudalics  <rudalics@gmx.at>

        * w32term.c (x_set_window_size): Refine fix from 2014-03-14

        * xdisp.c (redisplay_window): If all previous attempts to find the
        cursor row failed, try a few alternatives before falling back to
        the top-most row of the window.  Use row_containing_pos.  (Bug#17047)

2014-03-26  Juanma Barranquero  <lekktu@gmail.com>

        * image.c (x_bitmap_height, x_bitmap_width) [HAVE_X_WINDOWS]:

        * w32notify.c (watch_worker): Remove unnecesary var sleep_result.
        (start_watching): Remove unused var `thr'.

        * w32proc.c (sys_spawnve): Comment out unused vars `first', `last'.
        (find_child_console): Remove unnecesary var `thread_id'.

2014-03-25  Eli Zaretskii  <eliz@gnu.org>

        * w32.c (w32_delayed_load): Call DisableThreadLibraryCalls on the
        DLL handle, to speed up thread startup.

2014-03-25  Paul Eggert  <eggert@cs.ucla.edu>

        Handle sigmask better with nested signal handlers  (Bug#15561).
        * atimer.c (sigmask_atimers): Remove.
        Remaining use rewritten to use body of this function.
        * atimer.c (block_atimers, unblock_atimers):
        * callproc.c (block_child_signal, unblock_child_signal):
        * sysdep.c (block_tty_out_signal, unblock_tty_out_signal):
        New arg OLDSET.  All callers changed.
        * atimer.c (block_atimers, unblock_atimers):
        * callproc.c (block_child_signal, unblock_child_signal):
        * keyboard.c (handle_interrupt):
        * sound.c (vox_configure, vox_close):
        Restore the old signal mask rather than unilaterally clearing bits
        from the mask, in case a handler is running within another
        handler.  All callers changed.
        * lisp.h, process.c, process.h, term.c:
        Adjust decls and callers to match new API.
        * sysdep.c (emacs_sigaction_init): Don't worry about masking SIGFPE;
        signal handlers aren't supposed to use floating point anyway.
        (handle_arith_signal): Unblock just SIGFPE rather than clearing mask.

2014-03-23  Daniel Colascione  <dancol@dancol.org>

        Split gc_sweep into discrete functions for legibility and better
        stack traces.

        * alloc.c (sweep_strings, sweep_vectors): Add NO_INLINE

2014-03-23  Daniel Colascione  <dancol@dancol.org>

        * xfns.c (create_frame_xic): Pass XNStatusAttributes to XCreateIC
        only if xic_style calls for it.  This change allows Emacs to work
        with ibus.  Also, don't leak resources if create_frame_xic fails,
        and stop caching xic_style across different displays.
        (supported_xim_styles): Make const.
        (best_xim_style): Remove first parameter: it's always just
        supported_xim_styles.  Change to look at supported_xim_styles
        directly.

2014-03-23  Daniel Colascione  <dancol@dancol.org>

2014-03-22  Daniel Colascione  <dancol@dancol.org>

        * process.c (conv_sockaddr_to_lisp): When extracting the string
        names of AF_LOCAL sockets, stop before reading uninitialized memory.

2014-03-21  YAMAMOTO Mitsuharu  <mituharu@math.s.chiba-u.ac.jp>

        Fix regression introduced by patch for Bug#10500.
        * xterm.c (x_draw_image_relief): Respect Vtool_bar_button_margin.
        * w32term.c (x_draw_image_relief): Likewise.

2014-03-21  Martin Rudalics  <rudalics@gmx.at>

        * w32fns.c (w32_wnd_proc): For WM_WINDOWPOSCHANGING don't
        constrain frame size in SW_SHOWMAXIMIZED case so we can truly
        maximize a frame for odd default fonts.

2014-03-21  Glenn Morris  <rgm@gnu.org>

        * minibuf.c (history-length): Increase default from 30 to 100.

2014-03-21  Daniel Colascione  <dancol@dancol.org>

        * xterm.c (x_bitmap_icon): Stop reading the icon bitmap from disk
        every time we switch to minibuffer.

        * alloc.c (lisp_align_malloc, allocate_string_data)
        (allocate_vectorlike): Allow mmap allocation of lisp objects.

2014-03-21  Eli Zaretskii  <eliz@gnu.org>

        * w32fns.c (Fw32_shell_execute) [!CYGWIN]: Use ShellExecuteEx, to
        support more "verbs".

2014-03-21  Daniel Colascione  <dancol@dancol.org>

        Always prohibit dumping a dumped Emacs.

        * emacs.c (might_dump): New variable.
        (Fdump_emacs): Always prohibit dumping of dumped Emacs.
        * lisp.h (might_dump): Declare.

        put a docstring.
        (Fsubstitute_command_keys): Don't advertise the fact that
        text-properties are dropped, since we think it's a bug that we'll fix.

        * frame.h (SET_FRAME_VISIBLE): Keep frame_garbaged up to date.
        * xterm.c (handle_one_xevent) <MapNotify>: Don't garbage the frame.

        Fix porting inconsistency about rounding to even.
        * floatfns.c (emacs_rint) [!HAVE_RINT]: Round to even.
        This way, the unusual !HAVE_RINT case acts like the usual
        HAVE_RINT case, and we can fix the documentation accordingly.

2014-03-19  Eli Zaretskii  <eliz@gnu.org>

        * w32fns.c (reset_modifiers): Zero out keystate[] before using it.
        (w32_wnd_proc): Initialize the dwHoverTime member of
        TRACKMOUSEEVENT structure.

2014-03-17  Teodor Zlatanov  <tzz@lifelogs.com>

2014-03-16  Eli Zaretskii  <eliz@gnu.org>

        * search.c (find_newline): Speed up the function when using the
        newline cache, by halving the number of calls to
        region_cache_forward and region_cache_backward.  (Bug#16830)

2014-03-15  Juanma Barranquero  <lekktu@gmail.com>

        * buffer.c (Fset_buffer): Document return value (bug#17015).

2014-03-14  Martin Rudalics  <rudalics@gmx.at>

        * w32term.c (x_set_window_size): When frame-resize-pixelwise is
        nil, always resize character wise to avoid potential loss of the
        mode line (Bug#16923 related).

2014-03-12  Martin Rudalics  <rudalics@gmx.at>

        * frame.c (x_set_frame_parameters): Always calculate new sizes
        pixelwise to avoid potential loss when rounding.

2014-03-11  Dmitry Antipov  <dmantipov@yandex.ru>

        * xfns.c (x_set_mouse_color): Recolor vertical_drag_cursor.
        * xterm.c (x_free_frame_resources): Free all allocated cursors.

2014-03-10  Eli Zaretskii  <eliz@gnu.org>

        * w32.c (fstatat): Don't add an extra slash if the argument ends
        with a slash: this fails the subsequent call to stat_worker on
        Windows 9X.  Reported by oslsachem <oslsachem@gmail.com>.

2014-03-09  Martin Rudalics  <rudalics@gmx.at>

        * xdisp.c (Fwindow_text_pixel_size): Adjust doc-string.

        when frame is only on one screen (Bug#14713).

2014-03-08  Eli Zaretskii  <eliz@gnu.org>

        * xdisp.c (move_it_in_display_line_to): If word-wrap is ON, and
        there's a valid wrap point in the display line, the last glyph
        cannot "just barely fit" on this row, because display_line doesn't
        let it.  Instead, proceed as if the last glyph didn't fit, so that
        we eventually back up the iterator to the wrap point.  This avoids
        delusional behavior of move_it_to, whereby it proceeds to the next
        display line, but sets current_x to zero for all the glyphs that
        without word-wrap would fit on the previous display line.
        One result was that visual-order cursor movement behaved erratically
        under word-wrap.
        (Fmove_point_visually): Add code to find the x coordinate of the
        last character before wrap point, under word-wrap on a TTY.

2014-03-07  Eli Zaretskii  <eliz@gnu.org>

        * xdisp.c (Fmove_point_visually): When under word-wrap, accept
        also return value of MOVE_POS_MATCH_OR_ZV from
        move_it_in_display_line_to, when moving from beginning of line to
        point's position.  (Bug#16961)

2014-03-07  Martin Rudalics  <rudalics@gmx.at>

        * buffer.c (Vbuffer_list_update_hook): Doc-string fix.
        * window.c (Fselect_window): Explain NORECORD and
        `buffer-list-update-hook' in doc-string.

2014-03-06  Martin Rudalics  <rudalics@gmx.at>

        * window.c (Fother_window_for_scrolling): Check that
        Vother_window_scroll_buffer is a buffer.

2014-03-06  Dmitry Antipov  <dmantipov@yandex.ru>

        * xterm.c (xim_initialize): Always pass a copy of resource name
        to XRegisterIMInstantiateCallback and eassert whether return
        value is True.  Passing copy is important because Xlib doesn't
        make its own copy and resource name argument usually points to
        SSDATA (Vx_resource_name), which may be changed from Lisp.
        (xim_close_display): For XUnregisterIMInstantiateCallback,
        always eassert return value and pass exactly the same values
        as were used for XRegisterIMInstantiateCallback.
        Otherwise XUnregisterIMInstantiateCallback will always fail.  See Xlib
        sources to check why if you are interested.

2014-03-05  Martin Rudalics  <rudalics@gmx.at>

        * dispnew.c (change_frame_size_1): Add new_lines instead of
        new_height, the latter may be still zero if passed as such.
        * window.c (Fwindow_pixel_height): Mention bottom divider in
        doc-string.

2014-03-05  Paul Eggert  <eggert@cs.ucla.edu>

        Fix "resource temporarily unavailable" with xgselect
        (Bug#16925).
        * xgselect.c: Include <stdbool.h>.
        (xg_select) [!USE_GTK]: Don't lose track of errno.

        Fix minor --enable-gcc-warnings issues.
        * widget.c (update_various_frame_slots, EmacsFrameResize):
        Avoid unused locals.  Prefer 'if' to '#if' when either will do.

2014-03-04  Ken Brown  <kbrown@cornell.edu>

        * gmalloc.c (aligned_alloc): Clarify the code by making `adj'
        represent the actual adjustment needed for alignment.

2014-03-04  Eli Zaretskii  <eliz@gnu.org>

        * gmalloc.c (aligned_alloc): Don't allocate more memory than
        needed, and don't reallocate if the initial allocation already
        fits the bill.  Suggested by Ken Brown <kbrown@cornell.edu>.

2014-03-04  YAMAMOTO Mitsuharu  <mituharu@math.s.chiba-u.ac.jp>

        * xterm.c (x_draw_stretch_glyph_string): Reset clipping.
        (Bug#16932)

2014-03-04  Michal Nazarewicz  <mina86@mina86.com>

        * cmds.c (delete-char): Update docstring pointing out that the
        function ignores `delete-active-region' and `overwrite-mode'.

2014-03-03  Eli Zaretskii  <eliz@gnu.org>

        * font.c (Fframe_font_cache): Fix last change.  (Bug#16930)

        * gmalloc.c (aligned_alloc): Fix adjustment of size of the
        allocated buffer due to alignment.
        (freehook): If the block to be freed was allocated by
        'aligned_alloc', find its real pointer before calling 'free'.
        (Bug#16901)
        (mabort) [emacs]: Call 'emacs_abort', not 'abort', to provide a
        backtrace.

2014-03-03  Dmitry Antipov  <dmantipov@yandex.ru>

        * font.c (toplevel): Adjust comment about font cache layout.
        (font_clear_cache): Fix to match real font cache layout.
        Suggested by <namespace_collision@yahoo.com> in Bug#16069.
        (Fframe_font_cache) [FONT_DEBUG]: New function.
        (syms_of_font) [FONT_DEBUG]: Defsubr it.

        Avoid crashes when X fonts are erroneously freed on reused X
        'Display *' connection data (Bug#16069).  Note that X font
        resources still may be leaked, but currently there is no way
        to completely avoid it.
        * xterm.h (struct x_display_info): New member x_id.  Add comments.
        * xterm.c (x_display_id): New variable.
        (x_term_init): Assign identifier to each opened X connection.
        * xfont.c (struct xfont): New member x_display_id.
        (xfont_open): Initialize it with frame's display id.
        (xfont_close): Check whether font's display id matches the one
        recorded for the given display.  Adjust comment.
        * xftfont.c (struct xftfont_info):
        (xftfont_open, xftfont_close): Exactly as above with xfont stuff.

2014-03-01  Martin Rudalics  <rudalics@gmx.at>

        Consider Vother_window_scroll_buffer valid iff it's a live buffer.
        * window.c (Fother_window_for_scrolling): Don't try to scroll a
        killed Vother_window_scroll_buffer.
        (Vother_window_scroll_buffer): Fix doc-string accordingly.

2014-03-01  Eli Zaretskii  <eliz@gnu.org>

        * fileio.c (Fexpand_file_name) [WINDOWSNT]: Don't treat file names
        that start with more than 2 slashes as UNCs.  (Bug#16751)

2014-02-28  Paul Eggert  <eggert@penguin.cs.ucla.edu>

        Fix a few crashes and leaks when cloning C strings.
        * alloc.c, lisp.h (dupstring): New function.
        * gtkutil.c (xg_get_font):
        * term.c (tty_default_color_capabilities):
        * xsettings.c (store_monospaced_changed)
        (store_font_name_changed, parse_settings)
        (read_and_apply_settings, init_gsettings, init_gconf): Use it.
        This avoids some unlikely crashes due to accessing freed storage,
        and avoids some minor memory leaks in the more-typical case.

2014-02-28  Martin Rudalics  <rudalics@gmx.at>

        * xdisp.c (note_mode_line_or_margin_highlight): Don't show drag
        cursor when modeline can't be dragged (Bug#16647).

2014-02-28  Glenn Morris  <rgm@gnu.org>

        * doc.c (Fsnarf_documentation): Snarf not-yet-bound variables
        from custom-delayed-init-variables.  (Bug#11565)

2014-02-27  Martin Rudalics  <rudalics@gmx.at>

        More fixes for mouse glyph calculations (Bug#16647).
        * window.c (coordinates_in_window): In intersection of
        horizontal and vertical window dividers prefer the horizontal
        one.  Add some extra parens to last fix.
        (window_relative_x_coord): Return x-coordinate for header and
        mode line too.
        * xdisp.c (remember_mouse_glyph): In text area don't extend
        glyph into mode line to show the vertical drag cursor there
        immediately.  Subdivide mouse glyphs in right fringes to show a
        horizontal drag cursor as soon as we enter the "grabbable width"
        portion.  Handle vertical border case separately.  Do not
        subdivide window divider areas.
        (note_mouse_highlight): On bottom divider of bottommost windows
        show vertical drag cursor only when the minibuffer window can be
        resized.

2014-02-27  Eli Zaretskii  <eliz@gnu.org>

        * xdisp.c (pop_it): Restore the it->face_box_p flag which could be
        reset by the face of the object just displayed.  See also bug#76.
        (get_next_display_element): If the string came from a display
        property, examine the box face attribute at it->position, not at
        it->current.pos, since the latter was not updated yet.  (Bug#16870)
        (handle_face_prop): Improve commentary.

2014-02-27  Michael Albinus  <michael.albinus@gmx.de>

        * dbusbind.c (Fdbus__init_bus, Qdbus__init_bus, Sdbus__init_bus):
        Rename from Fdbus_init_bus_1, Qdbus_init_bus_1, Sdbus_init_bus_1.

2014-02-26  Martin Rudalics  <rudalics@gmx.at>

        Fixes around Bug#16647.
        * xdisp.c (remember_mouse_glyph): Handle ON_RIGHT_DIVIDER and
        ON_BOTTOM_DIVIDER cases.
        * window.c (coordinates_in_window): Return ON_VERTICAL_BORDER
        only if the window has no right divider.
        (Fcoordinates_in_window_p): Fix doc-string.

2014-02-25  Juanma Barranquero  <lekktu@gmail.com>

        * lread.c (Funintern): Fix doc to match advertised calling convention.

2014-02-24  Daniel Colascione  <dancol@dancol.org>

        * keyboard.c (read_char): Close race that resulted in lost events.

2014-02-22  Glenn Morris  <rgm@gnu.org>

        * frame.c (frame-alpha-lower-limit, frame-resize-pixelwise):
        * window.c (window-resize-pixelwise): Doc fixes.

        * process.c (Finternal_default_process_filter)
        (Finternal_default_process_sentinel): Doc tweaks.

2014-02-21  Glenn Morris  <rgm@gnu.org>

        * process.c (Fprocess_buffer, Faccept_process_output)
        (Finternal_default_process_filter, Finternal_default_process_sentinel):
        Doc fixes.

2014-02-21  Martin Rudalics  <rudalics@gmx.at>

        * window.c (Fwindow_scroll_bar_width): New function.

2014-02-21  Paul Eggert  <eggert@cs.ucla.edu>

        Pacify GCC when configuring with --enable-gcc-warnings.
        * xdisp.c (move_it_in_display_line_to) [lint]:
        Initialize recently-added local.

2014-02-21  Daniel Colascione  <dancol@dancol.org>

        * dbusbind.c: Rename dbus-init-bus to dbus-init-bus-1.

2014-02-20  Eli Zaretskii  <eliz@gnu.org>

        * xdisp.c (init_iterator): Don't dereference a bogus face
        pointer.  (Bug#16819)
        (try_cursor_movement): Don't use cursor position if
        set_cursor_from_row failed to compute it.  This avoids assertion
        violations in MATRIX_ROW.
        (move_it_in_display_line_to): Save the iterator state in ppos_it
        only once per call.  Reimplement the method used to return to the
        best candidate position if all the positions found in display line
        are beyond TO_CHARPOS.  This cuts down the number of calls to
        bidi_shelve_cache, which moves a lot of stuff when lines are long
        and include bidirectional text.  (Bug#15555)

2014-02-20  Glenn Morris  <rgm@gnu.org>

        * data.c (Fdefalias): Doc fix.

2014-02-19  Eli Zaretskii  <eliz@gnu.org>

        * xdisp.c (display_line): Fix horizontal scrolling of large images
        when fringes are turned off.  This comes at a price of not
        displaying the truncation/continuation glyphs in this case.
        (Bug#16806)

        * image.c (x_create_x_image_and_pixmap) [HAVE_NTGUI]: If
        CreateDIBSection returns an error indication, zero out *ximg after
        destroying the image.  This avoids crashes in memory allocations
        due to the fact that some of the callers also call
        x_destroy_x_image, which will attempt to free an already free'd
        block of memory.

2014-02-18  Martin Rudalics  <rudalics@gmx.at>

        * widget.c (update_various_frame_slots): Don't set
        FRAME_PIXEL_HEIGHT and FRAME_PIXEL_WIDTH here (Bug#16736).

2014-02-18  Michael Albinus  <michael.albinus@gmx.de>

        * dbusbind.c (xd_close_bus): Apply proper check on busobj.

2014-02-17  Paul Eggert  <eggert@cs.ucla.edu>

        temacs --daemon fix (Bug#16599).
        * emacs.c (main): Initialize daemon_pipe[1] here ...
        (syms_of_emacs): ... instead of here.

2014-02-16  Anders Lindgern  <andlind@gmail.com>

        * nsterm.m (keyDown:): Check for normal key even if NSNumericPadKeyMask
        is set (Bug#16505).

2014-02-16  Daniel Colascione  <dancol@dancol.org>

        * dbusbind.c (xd_lisp_dbus_to_dbus): New function.
        (xd_get_connection_address): Use it.
        (xd_close_bus): Use xd_lisp_dbus_to_dbus to instead of
        xd_get_connection_address because the latter signals if the bus
        we're trying to close is already disconnected.

2014-02-13  Eli Zaretskii  <eliz@gnu.org>

        * w32proc.c (start_timer_thread): Pass a non-NULL pointer as last
        argument to CreateThread.  This avoids segfaults on Windows 9X.
        Reported by oslsachem <oslsachem@gmail.com>.

2014-02-13  Paul Eggert  <eggert@cs.ucla.edu>

        Fix subspace record bug on HP-UX 10.20 (Bug#16717).
        * unexhp9k800.c (unexec_error): New function, to simplify the code.
        (check_lseek): New function, to report lseek errors.
        (save_data_space, update_file_ptrs, read_header, write_header)
        (copy_file, copy_rest, unexec): Use these news functions.
        (update_file_ptrs): Don't assume wraparound behavior when
        converting a large size_t value to off_t.

2014-02-13  Dmitry Antipov  <dmantipov@yandex.ru>

        * composite.c (fill_gstring_header): Pass positions as C integers
        and move parameters checking to...
        (Fcomposition_get_gstring): ...this function.  Handle case when
        buffer positions are in reversed order and avoid crash (Bug#16739).
        Adjust docstring.
        * buffer.c (validate_region): Mention current buffer in error message.

2014-02-12  Marcus Karlsson  <mk@acc.umu.se>  (tiny change)

        * image.c (pbm_load): Set to NO_PIXMAP on error (Bug#16683).

2014-02-12  Lars Ingebrigtsen  <larsi@gnus.org>

        * buffer.c (syms_of_buffer): Doc clarification (bug#9981).

2014-02-11  Glenn Morris  <rgm@gnu.org>

        * nsfns.m (ns_display_info_for_name, Fx_open_connection):
        Replace refs to "OpenStep" in messages.

2014-02-10  Paul Eggert  <eggert@cs.ucla.edu>

        Avoid "." at end of error diagnostics.
        * cmds.c (Fself_insert_command): Reword and avoid "." at end.
        * font.c (Ffont_at):
        * nsfns.m (ns_display_info_for_name):
        * nsselect.m (Fx_own_selection_internal):
        * nsterm.m (performDragOperation:):
        Remove "." from end of diagnostic.

2014-02-10  Lars Ingebrigtsen  <larsi@gnus.org>

        * fns.c (Fmaphash): Say what `maphash' returns, since it may be
        unintuitive (bug#15824).
        (Fyes_or_no_p): Doc fix (bug#15456).

2014-02-10  Dmitry Antipov  <dmantipov@yandex.ru>

        * cmds.c (Fself_insert_command): Respect the width of EMACS_INT
        and avoid warning.
        * eval.c (call_debugger): When exiting the debugger, do not allow
        max_specpdl_size less than actual binding depth (Bug#16603).
        (syms_of_eval): Adjust docstring.

2014-02-09  Lars Ingebrigtsen  <larsi@gnus.org>

        * cmds.c (Fself_insert_command): Output a clearer error message on
        negative repetitions (bug#9476).

        * macros.c (Fexecute_kbd_macro): Doc fix (bug#14206).

2014-02-08  Lars Ingebrigtsen  <larsi@gnus.org>

        * minibuf.c (Fread_string): Doc clarification (bug#15422).

        * buffer.c (Fmake_overlay): Doc clarification (bug#15489).

2014-02-08  Juanma Barranquero  <lekktu@gmail.com>

2014-02-08  Lars Ingebrigtsen  <larsi@gnus.org>

        * xdisp.c (syms_of_xdisp): Doc clarification (bug#15657).

        * keyboard.c (Frecursive_edit): Say more precicely how throwing
        `exit' works (bug#15865).

2014-02-07  Martin Rudalics  <rudalics@gmx.at>

        Constrain window box/body sizes and margin widths (Bug#16649).

        * window.c (window_body_height, window_body_width): Don't return
        negative value.
        (window_resize_apply): Adjust margin width, if necessary.

        * nsterm.m (syms_of_nsterm): Doc fix.

2014-02-06  Eli Zaretskii  <eliz@gnu.org>

        * w32.c (pMultiByteToWideChar, pWideCharToMultiByte):
        New variables: pointers through which to call the respective APIs.
        (filename_to_utf16, filename_from_utf16, filename_to_ansi)
        (filename_from_ansi, sys_link, check_windows_init_file):
        Call MultiByteToWideChar and WideCharToMultiByte through pointers.
        This is required on Windows 9X, where we dynamically load
        UNICOWS.DLL which has their non-stub implementations.
        (maybe_load_unicows_dll): Assign addresses to these 2 function
        pointers after loading UNICOWS.DLL.

        * w32fns.c (Fx_file_dialog, Fw32_shell_execute) [!CYGWIN]: Call
        MultiByteToWideChar and WideCharToMultiByte through function
        pointers.

        * w32.h (pMultiByteToWideChar, pWideCharToMultiByte):
        New declarations.

2014-02-06  Jan Djärv  <jan.h.d@swipnet.se>

        * nsterm.m (toggleFullScreen:): Hide menubar on secondary monitor
        for OSX >= 10.9 if separate spaces are used.
        (toggleFullScreen:): Use screen of w instead of fw (Bug#16659).

2014-02-06  Glenn Morris  <rgm@gnu.org>

        * buffer.c (cache-long-scans): Doc fix.

2014-02-05  Eli Zaretskii  <eliz@gnu.org>

        * w32fns.c (Fw32_shell_execute): Doc fix.

2014-02-05  Bastien Guerry  <bzg@gnu.org>

        * syntax.c (Fforward_word): Call Fconstrain_to_field with
        ESCAPE-FROM-EDGE set to `nil' (Bug#16453).

2014-02-04  Paul Eggert  <eggert@cs.ucla.edu>

        * menu.c (Fx_popup_dialog): Remove label 'dialog_via_menu'.
        It prompted a compile-time diagnostic on GNU/Linux.
        Simplify to remove the need for the label.

2014-02-04  Eli Zaretskii  <eliz@gnu.org>

        * w32menu.c (w32_popup_dialog): Don't condition the whole function
        on HAVE_DIALOGS.  If the dialog is "simple", pop up a message box
        to show it; otherwise return 'unsupported--w32-dialog' to signal
        to the caller that emulation with menus is necessary.
        This resurrects code inadvertently deleted by the 2013-10-08 commit.
        (Bug#16636)
        (syms_of_w32menu): DEFSYM Qunsupported__w32_dialog.

        * w32term.h (w32_popup_dialog): Prototype is no longer conditioned
        by HAVE_DIALOGS.

        * menu.c (Fx_popup_dialog): Don't condition the call to
        w32_popup_dialog on HAVE_DIALOGS.  If w32_popup_dialog returns a
        special symbol 'unsupported--w32-dialog', emulate the dialog with
        a menu by calling x-popup-menu.

        * menu.h (Qunsupported__w32_dialog): New extern variable.

2014-02-04  Michael Albinus  <michael.albinus@gmx.de>

        * keyboard.c (kbd_buffer_get_event): Read file notification events
        also in batch mode.

        * xgselect.c (xg_select): Read glib events in any case, even if
        there are no file descriptors to watch for.  (Bug#16519)

2014-02-03  Martin Rudalics  <rudalics@gmx.at>

        * dispextern.h (face_id): Add WINDOW_DIVIDER_FIRST_PIXEL_FACE_ID
        and WINDOW_DIVIDER_LAST_PIXEL_FACE_ID.
        * w32term.c (w32_draw_window_divider): Handle first and last
        pixels specially.
        * w32term.h (w32_fill_area_abs): New function.
        * xdisp.c (x_draw_right_divider): Don't draw over bottom
        divider.
        * xfaces.c (realize_basic_faces): Handle new face ids.
        * xfns.c (Fx_create_frame): Call x_default_parameter for right
        and bottom divider width.

        (Bug#16013).  Don't set pixel sizes since change_frame_size

        * emacs.c (main) [HAVE_W32NOTIFY]: When non-interactive, call
        init_crit, since init_display, which does that otherwise, is not

        * Makefile.in (OLDXMENU_TARGET, OLDXMENU, OLDXMENU_DEPS)
        (really-lwlib, really-oldXMenu, stamp-oldxmenu)
        (../src/$(OLDXMENU), $(OLDXMENU)): Remove.
        (temacs$(EXEEXT)): Depend on $(LIBXMENU), not stamp-oldxmenu.

        Fix recently introduced bool vector overrun.
        This was due to an optimization that went awry.
        Reported by Glenn Morris in
        <http://lists.gnu.org/archive/html/emacs-devel/2013-11/msg00622.html>.
        * alloc.c (make_uninit_bool_vector): Don't allocate a dummy word
        for empty vectors, undoing the 2013-11-18 change.
        * data.c (bool_vector_binop_driver): Rely on this.
        Fix bug that occasionally overran the destination.
        * lisp.h (struct Lisp_Bool_vector): Document this.

2013-11-20  Jan Djärv  <jan.h.d@swipnet.se>

2013-11-18  Paul Eggert  <eggert@cs.ucla.edu>

        * data.c (bool_vector_binop_driver): Rename locals for sanity's sake.
        The old names predated the API change that put destination at end.

        Improve API of recently-added bool vector functions (Bug#15912).
        The old API had (bool-vector-count-matches A B)
        and (bool-vector-count-matches-at A B I), which gave the
        misleading impression that the two functions were variants, one
        with a location I.  The new API has (bool-vector-count-population A)
        and (bool-vector-count-consecutive A B I) to make the distinction
        clearer.  The first function no longer has a B argument, since the
        caller can easily determine the number of nils if the length and
        number of ts is known.
        * data.c (Fbool_vector_count_population): Rename from
        bool_vector_count_matches, and accept just 1 argument.
        (Fbool_vector_count_consecutive): Rename from
        Fbool_vector_count_matches_at.

2013-11-17  Eli Zaretskii  <eliz@gnu.org>

        * w32term.c (x_update_window_end): Don't invalidate the entire
        mouse-highlight info, just signal frame_up_to_date_hook that mouse
        highlight needs to be redisplayed.  (Bug#15913)

2013-11-17  Paul Eggert  <eggert@cs.ucla.edu>

        * lisp.h (DEBUGGER_SEES_C_MACROS): Remove.

2013-11-16  Eli Zaretskii  <eliz@gnu.org>

        * doc.c (Fsubstitute_command_keys): Inhibit modification hooks
        while we are using Vprin1_to_string_buffer.

        * keymap.c (describe_map): Don't crash if PT is 1 both before and
        after inserting the description string.  (Bug#15907)

2013-11-15  Paul Eggert  <eggert@cs.ucla.edu>

        * data.c: Work around bogus GCC diagnostic about shift count.
        Reported by Eli Zaretskii in
        <http://lists.gnu.org/archive/html/emacs-devel/2013-11/msg00489.html>.
        (pre_value): New function.

2013-11-15  Eli Zaretskii  <eliz@gnu.org>

        * lisp.h (DEBUGGER_SEES_C_MACROS) [GCC < v3.5]: Pessimistically
        assume C macros are not supported even under -g3 in these old GCC
        versions.

2013-11-15  Leo Liu  <sdl.web@gmail.com>

        * minibuf.c (Ftry_completion, Fall_completions)

        * lisp.h (DEFINE_GDB_SYMBOL_BEGIN, DEFINE_GDB_SYMBOL_END):
        Define to empty if DEBUGGER_SEES_C_MACROS is defined.
        This avoids placing unnecessary constants into the Emacs code.

2013-11-14  Kazuhiro Ito  <kzhr@d1.dion.ne.jp>  (tiny change)

        * keyboard.c (make_ctrl_char) [HAVE_NTGUI]: Now externally visible
        for Cygwin w32 build.

        Simplify by using bool_vector_bytes.
        * alloc.c (make_uninit_bool_vector):
        New function, broken out from Fmake_bool_vector.
        (Fmake_bool_vector): Use it.  Use tail call.

        * data.c (BITS_PER_ULL): New constant.
        (ULLONG_MAX, count_one_bits_ll): Fall back on long counterparts
        if long long versions don't exist.
        (shift_right_ull): New function.
        (count_one_bits_word): New function, replacing popcount_bits_word
        macro.  Don't assume that bits_word is no wider than long long.
        (count_one_bits_word, count_trailing_zero_bits):
        Don't assume that bits_word is no wider than long long.

        contain at least one word.
        (bits_word_to_host_endian): Prefer if to #if.  Don't assume
        chars are narrower than ints.

        * fns.c (Fcopy_sequence):
        Simplify and tune.
        * lisp.h (bits_word, BITS_WORD_MAX, BITS_PER_BITS_WORD):

        (make_uninit_bool_vector): New decl.
        (bool_vector_fill): Now returns Lisp_Object.

        * xrdb.c (gethomedir): Prefer tail calls.

2013-11-12  Paul Eggert  <eggert@cs.ucla.edu>

        * xterm.c (syms_of_xterm): staticpro Qmodifier_value, Qalt, Qhyper,
        Qmeta, and Qsuper.  This is safer, and it's what w32fns.c does.

        that requires a return value.
        (Fset_buffer_modified_p): Take advantage of this change to do

2013-11-11  Paul Eggert  <eggert@cs.ucla.edu>

        * search.c (find_newline): Rewrite to prefer offsets to pointers.
        This avoids undefined behavior when subtracting pointers into
        different aways.  On my platform it also makes the code a tad
        smaller and presumably faster.

2013-11-11  Stefan Monnier  <monnier@iro.umontreal.ca>

        * keyboard.c (command_loop_1): Use region-extract-function.
        * insdel.c (Qregion_extract_function): Not static any more (can we
        stop pretending that these vars can benefit from being marked static?).

2013-11-09  Eli Zaretskii  <eliz@gnu.org>

        * search.c (find_newline): If buffer text is relocated during the
        "dumb loop", adjust C pointers into buffer text to follow suit.
        (Bug#15841)

2013-11-09  Łukasz Stelmach  <stlman@poczta.fm>  (tiny change)

        * gtkutil.c (xg_check_special_colors): Use rgb: instead of rgbi:

        unspecified (Bug#15815).

2013-11-08  Eli Zaretskii  <eliz@gnu.org>

        * xdisp.c (message_dolog): Make sure the *Messages* buffer has its
        cache-long-scans disabled, since we don't want to call
        prepare_to_modify_buffer (in insert_1_both) for each message we
        display.

        * buffer.h (bset_cache_long_scans): New INLINE function, moved
        from buffer.c.  Improve commentary to the buffer field setter
        functions.

        * buffer.c (bset_cache_long_scans): Static function deleted.
        Improve commentary to the buffer field setter functions.

        (Bug#15797)

2013-11-08  Paul Eggert  <eggert@cs.ucla.edu>

        * gmalloc.c (special_realloc, calloc, mallochook): Use tail calls.

        * chartab.c (make_sub_char_table): Fix size typo (Bug#15825).
        This bug was introduced in my 2013-06-21 change, and caused
        struct Lisp_Sub_Char_Table objects to be given too many slots,
        which broke 'make -C admin/unidata'.

2013-11-07  Jan Djärv  <jan.h.d@swipnet.se>

        Import changes from mac-port 4.5.
        * macfont.m (mac_font_copy_default_descriptors_for_language)

        (aligned_alloc): New function, defined or declared as needed.
        * conf_post.h (HAVE_POSIX_MEMALIGN) [DARWIN_OS]:

2013-11-06  Stefan Monnier  <monnier@iro.umontreal.ca>

        * *.[chm]: Number every assignment to windows_or_buffers_changed so we
        can track why it is set.

2013-11-06  Paul Eggert  <eggert@cs.ucla.edu>

        * callproc.c (call_process): Call prepare_to_modify_buffer before
        decoding text read from the sub-process, as the decoded stuff will
        be inserted into the buffer.  This will invalidate the various
        caches maintained for the buffer.  (Bug#15148)

2013-11-05  Xue Fuqiao  <xfq.free@gmail.com>

        * xdisp.c (syms_of_xdisp): Mention the active display table in doc

        (bits_word, BITS_WORD_MAX, BITS_PER_BITS_WORD): Fall back on
        unsigned char on unusual architectures, so that we no longer
        assume that the number of bits per bits_word is a power of two or

        resulting temporary name before returning it to the caller.
        (Fexpand_file_name): If NAME is pure-ASCII and DEFAULT_DIRECTORY
        is a unibyte string, convert NAME to a unibyte string to ensure
        that the result is also a unibyte string.

        * emacs.c (init_cmdargs): Use build_unibyte_string to make sure we
        create unibyte strings from default paths and directory/file

        but it was solved long ago.  (Bug#15260)

2013-11-04  Paul Eggert  <eggert@cs.ucla.edu>

        Port to stricter C99 platforms.
        Especially, C99 prohibits nesting a struct X inside struct Y if

        * alloc.c (struct sdata): New type.
        (sdata): Implement in terms of struct sdata.

        (Fbool_vector_not, Fbool_vector_count_matches_at):
        Remove uses of 'eassume' that should no longer be needed,
        because they are subsumed by the 'eassume' in bool_vector_size.

        * image.c (GIFLIB_MAJOR, GIFLIB_MINOR, GIFLIB_RELEASE): Move back
        after inclusion of gif_lib.h, thus fixing compiler warnings caused

        excluding the echo area.
        (tty_menu_activate): Limit the Y coordinate allowed by
        read_menu_input to the last screen line used for menu display.

2013-10-11  Paul Eggert  <eggert@cs.ucla.edu>

        * lisp.h (eassume): New macro.
        Also, include <verify.h>, for 'assume'.
        * alloc.c (bool_vector_payload_bytes, Fmake_bool_vector)
        (vroundup, vector_nbytes):
        * data.c (bool_vector_spare_mask, bool_vector_binop_driver)
        (Fbool_vector_not, Fbool_vector_count_matches)
        (Fbool_vector_count_matches_at):

2013-10-10  Dmitry Antipov  <dmantipov@yandex.ru>

        * keyboard.c (last_event_timestamp): Remove.  For X selection and

        (process_special_events): Adjust users.
        * keyboard.h (last_event_timestamp): Remove declaration.

        * intervals.c (temp_set_point_both): Move test into 'eassert',
        for speed.

        * lisp.h (eassert): Don't use 'assume'.
        Sometimes 'assume' wins in performance, and sometimes it loses,
        so it shouldn't be used all the time.  Perhaps we need two
        flavors of 'eassert', one for where 'assume' is far more likely
        to help or to hurt; but that can be done later.
        Problem reported by Dmitry Antipov in
        <http://lists.gnu.org/archive/html/emacs-devel/2013-10/msg00276.html>.
        Also, don't include <verify.h>; no longer needed.

        (save_and_enable_current_matrix): Omit unnecessary casts.

        (BITS_PER_BITS_WORD): Rename from BITS_PER_SIZE_T.  All uses changed.
        * data.c (popcount_bits_word): Rename from popcount_size_t.
        (bits_word_to_host_endian): Rename from size_t_to_host_endian.
        All uses changed.

2013-10-07  Paul Eggert  <eggert@cs.ucla.edu>

        Improve support for popcount and counting trailing zeros (Bug#15550).
        * data.c: Include <count-one-bits.h>, <count-trailing-zeros.h>.
        (USE_MSC_POPCOUNT, POPCOUNT_STATIC_INLINE)
        (NEED_GENERIC_POPCOUNT, popcount_size_t_generic)
        (popcount_size_t_msc, popcount_size_t_gcc):
        Remove; now done by Gnulib.
        (popcount_size_t): Now a macro that defers to Gnulib.
        (count_trailing_zero_bits): Return int, for consistency with
        Gnulib and because Emacs prefers signed to unsigned int.
        Don't assume that size_t is either unsigned int or unsigned long
        or unsigned long long.
        (size_t_to_host_endian): Do not assume that size_t is either
        exactly 32 or exactly 64 bits wide.
        * lisp.h (BITS_PER_SIZE_T): Define consistently with BITS_PER_LONG
        etc., so that it's now an enum constant, not a macro.
        No need to assume that it's either 32 or 64.

2013-10-07  Jan Djärv  <jan.h.d@swipnet.se>

        * nsterm.m (windowDidEnterFullScreen:): setPresentationOptions only
        on >= 10.7.

2013-10-07  Dmitry Antipov  <dmantipov@yandex.ru>

        * insdel.c (insert_from_gap): Prefer ptrdiff_t to int where needed.
        * xdisp.c (handle_fontified_prop): Likewise.  Use bool for boolean.

2013-10-07  Paul Eggert  <eggert@cs.ucla.edu>

        emacs_read and emacs_write now use void *, not char *.
        * alloc.c (valid_pointer_p) [!WINDOWSNT]: Remove now-unnecessary cast.
        * sysdep.c (emacs_read, emacs_write, emacs_write_sig):
        Buffer arg is now void *, not char *.  This matches plain
        'read' and 'write' better, and avoids a constraint violation
        on Solaris 9 with Oracle Studio.

2013-10-07  Dmitry Antipov  <dmantipov@yandex.ru>

        * alloc.c (Fmake_string): For ASCII char initializer, prefer
        memset to explicit loop.  Otherwise copy largest possible chunk
        from initialized to uninitialized part, thus allowing the longer
        memcpy runs and reducing the number of loop iterations.

2013-10-06  Jan Djärv  <jan.h.d@swipnet.se>

        * nsterm.m (ns_update_begin): If native fullscreen and no toolbar,
        hide toolbar (Bug#15388).
        (windowDidEnterFullScreen:): If presentation options are zero,
        set them here (Bug#15388).
        (ns_update_auto_hide_menu_bar): Remove runtime check.
        Don't auto hide dock unless menubar is also auto hidden.

2013-10-05  Xue Fuqiao  <xfq.free@gmail.com>

        * editfns.c (message): Mention batch mode in doc string.

2013-10-05  Jan Djärv  <jan.h.d@swipnet.se>

        * nsterm.m (check_native_fs): Remove erroneous comment.

2013-10-04  Dmitry Antipov  <dmantipov@yandex.ru>

        * xdisp.c (redisplay_internal): Simplify because scan_for_column now
        uses find_newline instead of scan_newline and so doesn't move point.

2013-10-04  Paul Eggert  <eggert@cs.ucla.edu>

        Use hardware support for byteswapping on glibc x86 etc.
        On Fedora 19 x86-64, the new bswap_64 needs 1 instruction,
        whereas the old swap64 needed 30.
        * fringe.c (init_fringe_bitmap) [WORDS_BIGENDIAN]:
        * sound.c (le2hl, le2hs, be2hl) [!WINDOWSNT]:
        Use byteswap.h's macros to swap bytes.
        * lisp.h (swap16, swap32, swap64): Remove.
        All uses replaced by bswap_16, bswap_32, bswap_64.

        * bytecode.c (exec_byte_code): Use some more volatile variables
        to work around local variables getting clobbered by longjmp.
        Port to pre-C99, which doesn't allow decls after stmts.

2013-10-03  Paul Eggert  <eggert@cs.ucla.edu>

        * lisp.h (eassert): Assume that COND is true when optimizing.
        In other words, take on the behavior of eassert_and_assume.
        This makes Emacs 0.2% smaller on my platform (Fedora 19, x86-64).
        (eassert_and_assume): Remove.  All uses replaced by eassert.

        * xdisp.c (Qglyphless_char): Now static.

        Adjust to merge from gnulib.
        * conf_post.h (__has_builtin, assume): Remove; gnulib now does these.
        * lisp.h: Include <verify.h>, for 'assume'.

        * eval.c (clobbered_eassert): New macro.
        (internal_catch, internal_condition_case)
        (internal_condition_case_1, internal_condition_case_2)
        (internal_condition_case_n): Use it instead of eassert
        when the argument contains locals clobbered by longjmp.
        Don't use clobbered locals outside of clobbered_eassert.
        (internal_lisp_condition_case): Use a volatile variable
        to work around a local variable's getting clobbered.

2013-10-03  Stefan Monnier  <monnier@iro.umontreal.ca>

        * lisp.h (struct handler): Merge struct handler and struct catchtag.
        (PUSH_HANDLER): New macro.
        (catchlist): Remove.
        (handlerlist): Always declare.

        * eval.c (catchlist): Remove (merge with handlerlist).
        (handlerlist, lisp_eval_depth): Not static any more.
        (internal_catch, internal_condition_case, internal_condition_case_1)
        (internal_condition_case_2, internal_condition_case_n):
        Use PUSH_HANDLER.
        (unwind_to_catch, Fthrow, Fsignal): Adjust to merged
        handlerlist/catchlist.
        (internal_lisp_condition_case): Use PUSH_HANDLER.  Adjust to new
        handlerlist which can only handle a single condition-case handler at
        a time.
        (find_handler_clause): Simplify since we only a single branch here
        any more.

        * bytecode.c (BYTE_CODES): Add Bpushcatch, Bpushconditioncase
        and Bpophandler.
        (bcall0): New function.
        (exec_byte_code): Add corresponding cases.  Improve error message when
        encountering an invalid byte-code.  Let Bunwind_protect accept
        a function (rather than a list of expressions) as argument.

        * alloc.c (Fgarbage_collect): Merge scans of handlerlist and catchlist,
        and make them unconditional now that they're heap-allocated.

2013-10-03  Stefan Monnier  <monnier@iro.umontreal.ca>

        * charset.c (Fdecode_char, Fencode_char): Remove description of
        `restriction' arg. now that it's hidden by advertised-calling-convention.

2013-10-02  Jan Djärv  <jan.h.d@swipnet.se>

        * macfont.m (mac_ctfont_create_preferred_family_for_attributes):
        Remove unused variable (from mac-port).
        (macfont_draw): Use s->ybase for correct y position.

2013-10-02  Dmitry Antipov  <dmantipov@yandex.ru>

        * frame.h (struct frame): Drop has_minibuffer member because...
        (FRAME_HAS_MINIBUF_P): ...this macro can be implemented without it.
        * frame.c (make_frame, make_minibuffer_frame): Adjust users.

2013-10-02  Dmitry Antipov  <dmantipov@yandex.ru>

        * window.h (struct window): Prefer enum text_cursor_kinds to int
        for phys_cursor_type member.  Move the latter, phys_cursor_width,
        phys_cursor_ascent and phys_cursor_height under HAVE_WINDOW_SYSTEM.
        * window.c (replace_window, make_window): Adjust users.

2013-10-02  Dmitry Antipov  <dmantipov@yandex.ru>

        * fringe.c (toplevel): Do not use HAVE_WINDOW_SYSTEM because
        this module is never compiled otherwise.

2013-10-01  Alp Aker  <alp.tekin.aker@gmail.com>

        * macfont.m (macfont_draw): Use CGRectMake rather than NSMakeRect
        (Bug#15500).

2013-09-29  Eli Zaretskii  <eliz@gnu.org>

        * xdisp.c (get_next_display_element): Don't call face_for_font in
        a build configured --without-x.  (Bug#15484)

2013-09-29  Jan Djärv  <jan.h.d@swipnet.se>

        * window.c (calc_absolute_offset): #elif should be #elif defined.

        * frame.c (delete_frame): Block/unblock input to overcome race
        condition (Bug#15475).

2013-09-24  Paul Eggert  <eggert@cs.ucla.edu>

        * dispnew.c (clear_glyph_row, copy_row_except_pointers): Use enums
        instead of ints, as it's the usual style for offsetof constants.  See:
        http://lists.gnu.org/archive/html/emacs-devel/2013-09/msg00478.html

        * data.c (POPCOUNT_STATIC_INLINE): New macro, as a hack for popcount.
        This is ugly, but it should fix the performance problem for older
        GCC versions in the short run.  I'll look into integrating the
        Gnulib module for popcount, as a better fix.
        See the thread starting in:
        http://lists.gnu.org/archive/html/emacs-devel/2013-09/msg00474.html

        No need for 'const' on locals that do not escape.
        Omit easserts with unnecessary and unportable assumptions about
        alignment.  Avoid unnecessary casts to char *.

2013-09-24  Dmitry Antipov  <dmantipov@yandex.ru>

        (bool_vector_binop_driver, count_trailing_zero_bits)
        (size_t_to_host_endian): Now static, not static inline;
        the latter isn't needed with modern compilers and doesn't
        work with older compilers anyway.

        * alloc.c (valgrind_p): Use bool for boolean.

2013-09-23  Dmitry Antipov  <dmantipov@yandex.ru>

2013-09-22  Paul Eggert  <eggert@cs.ucla.edu>

        Fix syntax.h bug introduced by recent INLINE change.
        syntax.h defined an extern inline function SYNTAX_ENTRY that was
        conditionally compiled one way in some modules, and a different
        way in others.  This doesn't work with extern inline functions,
        which must have the same definition in all modules, because the
        defining code might be shared across modules, depending on the
        implementation.  Symptoms reported by Martin Rudalics in:
        http://lists.gnu.org/archive/html/emacs-devel/2013-09/msg00414.html
        * regex.c, syntax.c (SYNTAX_ENTRY_VIA_PROPERTY): Remove.

        Do not copy X event in handle_one_xevent except KeyPress case.

        Fix corruption with multiple emacsclient -t instances (Bug#15222).

        assumed that the terminfo implementation doesn't use termcap buffers.
        * term.c (init_tty) [TERMINFO]: Remove optimization, as
        these buffers apparently are used after all.
        * termchar.h (TERMCAP_BUFFER_SIZE) [TERMINFO]: Define here too.

        (redisplay_internal): Look for cursor type change on each visible
        frame and consider all frames if cursor type has been changed on
        the frame other than selected.  If cursor type has been changed on

        * w32.c (term_winsock): Call release_listen_threads before calling
        WSACleanup.
        (_sys_wait_accept): Wait for accept event in a loop with a finite
        timeout, instead of waiting indefinitely.  Will hopefully avoid
        hanging during exit because WSACleanup deadlocks waiting for the
        event object to be released.  (Bug#14333)

        * w32proc.c (release_listen_threads): New function, signals all
        the reader threads that listen for connections to stop waiting.

        field of new marker (for sanity and safety).
        * lisp.h (XSETMARKER): Remove unused macro (it doesn't work
        anyway because XMISCTYPE is a function and can't be an lvalue).

2013-08-29  Dmitry Antipov  <dmantipov@yandex.ru>

        * xterm.c (x_clear_area): Lost 7th arg because it is always False.

2013-08-29  Dmitry Antipov  <dmantipov@yandex.ru>

        Hook scanning and indentation functions to find_newline.  This helps
        to avoid duplicated code and renders more respect to newline cache.
        * lisp.h (scan_newline): Prefer ptrdiff_t to EMACS_INT.
        * cmds.c (Fforward_line):
        * indent.c (scan_for_column, Fcurrent_indentation, indented_beyond_p):

        Remove unused macro definitions.
        (CHARSET_RANGE_TABLE_BITS, EXTEND_RANGE_TABLE)
        (SET_RANGE_TABLE_WORK_AREA_BIT, SET_RANGE_TABLE_WORK_AREA):
        Only define if emacs.

2013-08-28  Dmitry Antipov  <dmantipov@yandex.ru>

        Prefer enum glyph_row_area to int where appropriate.
        * dispextern.h (enum glyph_row_area): Add ANY_AREA member.
        Fix comment.
        (window_box, window_box_width, window_box_left, window_box_left_offset)

        * xdisp.c (window_box, window_box_width, window_box_left)

        * nsterm.m (ns_clip_to_row):
        * w32term.c (w32_clip_to_row):
        * xterm.c (x_clip_to_row): Likewise.

2013-08-28  Paul Eggert  <eggert@cs.ucla.edu>

        * Makefile.in (SHELL): Now @SHELL@, not /bin/sh,
        for portability to hosts where /bin/sh has problems.

2013-08-28  Dmitry Antipov  <dmantipov@yandex.ru>

        Redesign redisplay interface to drop global output_cursor.

        Adjust to use per-window output cursor.

2013-08-27  Paul Eggert  <eggert@cs.ucla.edu>

        Simplify SELECT_TYPE-related code.
        Like EMACS_TIME, this portability layer is no longer needed, since
        Emacs has been using fd_set as a portability layer for some time.
        * sysselect.h (FD_SETSIZE): Rename from MAXDESC.  All uses changed.
        (SELECT_TYPE): Remove.  All uses changed to fd_set.
        (fd_set) [!FD_SET]: New typedef.

        Simplify EMACS_TIME-related code.
        This portability layer is no longer needed, since Emacs has been
        using struct timespec as a portability layer for some time.
        * atimer.h, buffer.h, dispextern.h, xgselect.h:
        Include <time.h> rather than "systime.h"; that's all that's needed now.
        * dispnew.c: Include <timespec.h> rather than "systime.h";
        that's all that's needed now.
        * systime.h (EMACS_TIME): Remove.  All uses changed to struct timespec.

        changed to timespec_cmp.
        * xgselect.c: Include <timespec.h>, since our .h files don't.

2013-08-27  Dmitry Antipov  <dmantipov@yandex.ru>

        * xterm.h (FONT_TYPE_FOR_UNIBYTE, FONT_TYPE_FOR_MULTIBYTE:)
        * nsterm.h (FONT_TYPE_FOR_UNIBYTE, FONT_TYPE_FOR_MULTIBYTE):
        Remove the leftovers.
        * gtkutil.c (toplevel): Do not declare Qxft but include
        font.h to do so.
        * image.c (toplevel): Do not declare Vlibrary_cache because
        it's already done in lisp.h.

2013-08-27  Dmitry Antipov  <dmantipov@yandex.ru>

        * lisp.h (Mouse_HLInfo): Move from here...

2013-08-26  Paul Eggert  <eggert@cs.ucla.edu>

        Fix minor problems found by static checking.

        * nsterm.h, nsterm.m (ns_select):
        * xgselect.c, xgselect.h (xg_select):
        Adjust signature to better match pselect's.
        * nsterm.m (ns_select):
        Don't set *TIMEOUT, since pselect doesn't.
        * regex.c (whitespace_regexp): Now const_re_char *, to avoid
        diagnostic about assigning const char * to it.
        * xfaces.c (x_display_info) [HAVE_NS]: Remove; unused.

2013-08-26  Stefan Monnier  <monnier@iro.umontreal.ca>

2013-08-26  Paul Eggert  <eggert@cs.ucla.edu>

        Fix unlikely core dump in init_tty, and simplify terminfo case.
        * term.c (init_tty) [TERMINFO]: Fix check for buffer overrun.
        The old version incorrectly dumped core if malloc returned a
        buffer containing only non-NUL bytes.
        (init_tty): Do not allocate or free termcap buffers; the
        struct does that for us now.
        * termchar.h (TERMCAP_BUFFER_SIZE) [!TERMINFO]: New constant.
        (struct tty_display_info): Define members termcap_term_buffer and
        termcap_strings_buffer only if !TERMINFO, since terminfo doesn't
        use them.  Allocate them directly in struct rather than indirectly
        via a pointer, to simplify init_tty.

        * frame.c (check_minibuf_window): Initialize 'window' properly,
        so that Emacs reliably aborts later if 'window' is not initialized.

2013-08-26  Jan Djärv  <jan.h.d@swipnet.se>

        * gtkutil.c (xg_initialize): Set gtk-menu-bar-accel to "" instead

2013-08-26  Dmitry Antipov  <dmantipov@yandex.ru>

        * window.h (struct window): Replace last_cursor with last_cursor_vpos
        because this is the only last cursor data we need to keep and consult.
        * window.c (replace_window, set_window_buffer, Fsplit_window_internal):
        * xdisp.c (mark_window_display_accurate_1, try_cursor_movement):
        Adjust users.

2013-08-26  Dmitry Antipov  <dmantipov@yandex.ru>

        Fix recovering from possible decompression error.
        Since insert_from_gap doesn't always move point, we can't use PT as
        the position where the partially decompressed data ends, and
        should count how many bytes was produced so far.
        * decompress.c (struct decompress_unwind_data): Add nbytes member.
        (unwind_decompress): Really delete partially uncompressed data.
        (Fzlib_decompress_region): Take decompressed data size into account.

2013-08-26  Dmitry Antipov  <dmantipov@yandex.ru>

        * syntax.c (init_syntax_once): Adjust comment and do an early

        * casetab.c (init_casetab_once):
        * category.c (init_category_once):
        * character.c (syms_of_character):
        * coding.c (syms_of_coding):
        * xdisp.c (syms_of_xdisp): ...and omit it here.

2013-08-24  Eli Zaretskii  <eliz@gnu.org>

        * xdisp.c (get_next_display_element): Don't apply to characters
        from a display vector the logic of setting it->end_of_box_run_p
        suitable for characters from a buffer.  (Bug#15175)

        * w32.c (fdutimens): Call 'utime', which is implemented on w32.c
        to handle directories, rather than '_utime' which doesn't.
        (Bug#15176)

2013-08-24  Jan Djärv  <jan.h.d@swipnet.se>

        * gtkutil.c (x_wm_set_size_hint): Don't set hints when maximized
        or fullscreen (Bug#14627).

        System-dependent integer overflow fixes.
        * process.c (Fset_process_window_size): Signal an error if
        the window size is outside the range supported by the lower level.
        * sysdep.c (set_window_size): Return negative on error,
        nonnegative on success, rather than -1, 0, 1 on not in system,
        failure, success.  This is simpler.  Caller changed.
        (serial_configure): Remove unnecessary initialization of local.
        (procfs_get_total_memory) [GNU_LINUX]: Don't assume system memory
        size fits in unsigned long; this isn't true on some 32-bit hosts.
        Avoid buffer overrun if some future version of /proc/meminfo has a
        variable name longer than 20 bytes.
        (system_process_attributes) [__FreeBSD__]:
        Don't assume hw.availpages fits in 'int'.

2013-08-23  Paul Eggert  <eggert@cs.ucla.edu>

        Don't let very long directory names overrun the stack.
        Fix some related minor problems involving "//", vfork.

        (call_process): Don't append "/"; not needed.
        * fileio.c (file_name_as_directory_slop): New constant.
        (file_name_as_directory): Allow SRC to be longer than SRCLEN;
        this can save the caller having to alloca.
        (Ffile_name_as_directory, Fdirectory_file_name, Fexpand_file_name):
        Use SAFE_ALLOCA, not alloca.
        (directory_file_name, Fexpand_file_name): Leave leading "//"
        alone, since it can be special even on POSIX platforms.
        * callproc.c (call_process):
        * process.c (Fformat_network_address):
        * sysdep.c (sys_subshell):
        Use encode_current_directory rather than rolling our own.
        (create_process): No need to encode directory; caller does that now.
        * process.h (encode_current_directory): New decl.
        * sysdep.c (sys_subshell): Work even if vfork trashes saved_handlers.
        Rework to avoid 'goto xyzzy;'.

2013-08-23  Eli Zaretskii  <eliz@gnu.org>

        * xdisp.c (handle_face_prop): If the default face was remapped use
        the remapped face for strings from prefix properties.  (Bug#15155)

2013-08-23  Dmitry Antipov  <dmantipov@yandex.ru>

        Minor cleanup for redisplay interface and few related functions.

        enum text_cursor_kinds where appropriate.

2013-08-23  Dmitry Antipov  <dmantipov@yandex.ru>

        Redesign redisplay interface to drop updated_row and updated_area.
        * dispextern.h (updated_row, updated_area): Remove declaration.
        (struct redisplay_interface): Pass glyph row and row area parameters
        to write_glyphs, insert_glyphs and clear_end_of_line functions.
        (x_write_glyphs, x_insert_glyphs, x_clear_end_of_line):
        Adjust prototypes.

        Don't mistakenly kill process created by a call-process invocation
        that discards output and does not wait.

2013-08-21  Dmitry Antipov  <dmantipov@yandex.ru>

        Fix compilation with GC_MARK_STACK == GC_USE_GCPROS_AS_BEFORE
        and GC_MARK_STACK == GC_USE_GCPROS_CHECK_ZOMBIES.
        * alloc.c (toplevel): Remove unnecessary nested #if...#endif.
        (mark_maybe_object) [!GC_MARK_STACK]: Define to emacs_abort
        to shut up compiler in mark_object.
        (dump_zombies): Convert to global and add EXTERNALLY_VISIBLE.

2013-08-21  Paul Eggert  <eggert@cs.ucla.edu>

        * process.c (allocate_pty) [PTY_OPEN]: Set fd's FD_CLOEXEC flag.
        We can't portably rely on PTY_OPEN doing that, even if
        it calls posix_openpt with O_CLOEXEC.

2013-08-20  Kenichi Handa  <handa@gnu.org>

        * character.c (string_char): Improve commentary.

2013-08-20  Paul Eggert  <eggert@cs.ucla.edu>

        * image.c (SIGNATURE_DIGESTSIZE): Remove.
        (struct animation_cache): Make signature a flexible array member.
        All uses changed.  This is a tad slower but may insulate us better
        from future changes to ImageMagick.

2013-08-19  Paul Eggert  <eggert@cs.ucla.edu>

        * image.c: Shrink memory needed for animation cache.
        (SIGNATURE_DIGESTSIZE): New constant.
        (struct animation_cache): Make 'signature' a fixed size array of bytes.
        (imagemagick_create_cache): Copy the signature.  This saves
        several KB of memory that ImageMagick wastes per signature.
        Don't bother updating the update_time, as the caller does that now.
        (imagemagick_prune_animation_cache): Don't destroy the signature, as
        it's a fixed size struct member now.
        (imagemagick_get_animation_cache): Always destroy the signature,
        as it's now imagemagick_create_cache's responsibility to copy it.
        Avoid duplicate calls to strcmp and to imagemagick_create_cache,
        and use memcmp rather than strcmp.
        eassert that ImageMagick returns a signature of the specified length.

2013-08-19  Lars Magne Ingebrigtsen  <larsi@gnus.org>

        * image.c (imagemagick_get_animation_cache): Don't segfault on
        each invocation.
        (imagemagick_get_animation_cache): Revert to previous definition
        so that it actually works.  But keep the memory leak fix.
        (imagemagick_get_animation_cache): Fix memory leak.

2013-08-19  Paul Eggert  <eggert@cs.ucla.edu>

        * image.c: Fix animation cache signature memory leak.
        Fix some other minor performance problems while we're at it.
        (imagemagick_create_cache): Clear just the members that
        need clearing.  Don't set update_time, as caller does that now.
        (imagemagick_prune_animation_cache, imagemagick_get_animation_cache):
        Simplify by using pointer-to-pointer instead of a prev pointer.
        (imagemagick_prune_animation_cache): Use make_emacs_time rather
        than EMACS_TIME_FROM_DOUBLE, and DestroyString rather than free.
        (imagemagick_get_animation_cache): Don't xstrdup the image signature;
        it's already a copy.  Free the signature probe unless it's cached.

        * process.c (handle_child_signal): Fix crash; deleted pid (Bug#15106).
        This was introduced by my 2013-08-12 fix for Bug#15035.

2013-08-19  Dmitry Antipov  <dmantipov@yandex.ru>

        * image.c (imagemagick_create_cache, imagemagick_get_animation_cache)
        (imagemagick_prune_animation_cache): Now static.

2013-08-18  Lars Magne Ingebrigtsen  <larsi@gnus.org>

        * image.c (imagemagick_get_animation_cache): Don't segfault when
        pruning all entries.

2013-08-18  Ken Brown  <kbrown@cornell.edu>

        * sheap.c (STATIC_HEAP_SIZE): Adjust to current needs; use bigger
        static heap if ENABLE_CHECKING is defined.
        (max_bss_sbrk_ptr): New variable.
        (bss_sbrk): Use it.
        (report_sheap_usage): Report maximum static heap usage instead of
        ending static heap usage.

2013-08-17  Eli Zaretskii  <eliz@gnu.org>

        * decompress.c (Fzlib_available_p) [WINDOWSNT]: Update the value
        of zlib_initialized according to the results of calling
        init_zlib_functions.

2013-08-16  Lars Magne Ingebrigtsen  <larsi@gnus.org>

        * image.c: Implement an ImageMagick per-image cache.
        (imagemagick_get_animation_cache): Fix a double-free error.
        (imagemagick_load_image): Remove the ping_wand code, which only
        apparently saved time on invalid animated images, and slowed down
        everything else.  Optimise for the common case.

2013-08-16  Xue Fuqiao  <xfq.free@gmail.com>

        * buffer.c (syms_of_buffer) <buffer-undo-list>: Doc fix.

        * editfns.c (insert_before_markers): Mention overlay in the doc string.

        * marker.c (set_marker): Remove documentation of undefined behavior.

2013-08-15  Lars Magne Ingebrigtsen  <larsi@gnus.org>

        * image.c (imagemagick_compute_animated_image): Animate correctly
        when sub-images are smaller than the main image.
        (imagemagick_compute_animated_image): Setting the iterator row to
        zero is apparently not allowed.
        (imagemagick_compute_animated_image): Allow images that say they
        have sub-images that are bigger than the main image, but just crop
        them.

2013-08-15  Jan Djärv  <jan.h.d@swipnet.se>

        * nsmenu.m (menuWillOpen:): Fix preprocessor test (Bug#15001).

2013-08-15  Lars Magne Ingebrigtsen  <larsi@gnus.org>

        * image.c (imagemagick_compute_animated_image): Respect the GIF
        disposal methods.

2013-08-15  Ken Brown  <kbrown@cornell.edu>

        * emacs.c (main): Update comment about G_SLICE_ALWAYS_MALLOC.
        * gmalloc.c (memalign) [CYGWIN]: Revert last change; it's not
        needed.

2013-08-15  Paul Eggert  <eggert@cs.ucla.edu>

        Fix minor problems found by static checking.
        * frame.c (delete_frame):
        * xdisp.c (next_element_from_display_vector):
        Avoid uninitialized local.
        * image.c (imagemagick_compute_animated_image): Port to C89.
        Prefer usual GNU indentation style for loops.
        Be more careful about bizarrely large sizes, by using ptrdiff_t
        instead of int.

2013-08-15  Dmitry Antipov  <dmantipov@yandex.ru>

        Fix infinite frame selection loop (Bug#15025).
        * frame.c (delete_frame): Prefer fast ad-hoc loop to next_frame.

2013-08-15  Eli Zaretskii  <eliz@gnu.org>

        * xdisp.c (compute_window_start_on_continuation_line):
        When WORD_WRAP is in effect, use move_it_to instead of move_it_by_lines
        to make sure we end up setting the window start at the leftmost
        visible character of the display line.  This avoids funky
        horizontal shifting because the window start is not kept on the
        same position.  (Bug#15090)
        (next_element_from_display_vector): Support 'box' face attribute
        in the face definitions of a display vector.  (Bug#15099)

        * image.c (imagemagick_compute_animated_image): Implement animated
        images (bug#14700).
        (imagemagick_compute_animated_image): Fix some compilation
        warnings.  Implement a very simple cache to make the animation
        usable at all, but it should be replaced with a per-image cache.

2013-08-15  Dmitry Antipov  <dmantipov@yandex.ru>

        * lisp.h (FOR_EACH_ALIST_VALUE): New macro
        to do `for' loops over alist values.

        * process.c (FOR_EACH_PROCESS): Use it.
        (handle_child_signal, status_notify, Fget_buffer_process)
        (kill_buffer_processes): Use FOR_EACH_PROCESS.

2013-08-15  Dmitry Antipov  <dmantipov@yandex.ru>

        * term.c (get_named_tty, create_tty_output, tty_free_frame_resources)
        (tty_free_frame_resources, delete_tty): Prefer eassert to emacs_abort.
        * image.c (make_image_cache): For struct image_cache, prefer xmalloc
        to xzalloc and so avoid redundant call to memset.
        * xterm.c (x_term_init): Avoid unnecessary initializations of dpyinfo
        members because it is allocated with xzalloc and so already zeroed.

2013-08-14  Ken Brown  <kbrown@cornell.edu>

        * gmalloc.c (memalign) [CYGWIN]: Rename to emacs_memalign
        (Bug#15094).

        * image.c (x_create_bitmap_from_file):
        * w32term.c (w32_term_init):

2013-08-14  Lars Magne Ingebrigtsen  <larsi@gnus.org>

        * image.c (imagemagick_load_image): Make animated pictures work.
        There's still some problems with background color settings, though
        (bug#14700).

        Use changed.  This avoids the need to call xmalloc and for the
        caller to call xfree, and avoids memory leaks in some situations.

2013-08-14  Dmitry Antipov  <dmantipov@yandex.ru>

        * xdisp.c (adjust_window_ends): Move duplicated code to new function.
        (try_window, try_window_reusing_current_matrix, try_window_id): Use it.
        (redisplay_window): If window_end_valid is cleared due to non-zero
        windows_or_buffers_changed, clear current_matrix_up_to_date_p and
        so do not call to try_cursor_movement for that window.

2013-08-14  Dmitry Antipov  <dmantipov@yandex.ru>

        * window.h (struct window): Convert window_end_pos and

        (Fzlib_decompress_region): Don't bother verifying
        that avail_out <= UINT_MAX, as that was confusing.
        Mention the restriction in a comment instead.

        objects now.  This avoids crashes in GC.

        * w32term.h (struct scroll_bar): Convert fringe_extended_p to a
        bool, so its address could be taken.

2013-08-13  Lars Magne Ingebrigtsen  <larsi@gnus.org>

        * image.c (imagemagick_filename_hint): New function to possibly
        apply `image-content-type-suffixes'.

        (redisplay_window): Use it.

2013-08-12  Paul Eggert  <eggert@cs.ucla.edu>

        Fix some fd issues when running subprocesses (Bug#15035).
        Fix bugs that can leak files or file descriptors on errors.
        Don't unlink open temp files, as that's hard for users to diagnose
        when things go awry (e.g., temp disk exhausted).
        Don't bother to lock temp files.  Check for invalid recursion.
        * callproc.c (synch_process_fd): Remove.  All uses removed.
        (synch_process_tempfile): New var or macro.
        (CALLPROC_STDOUT, CALLPROC_STDERR, CALLPROC_PIPEREAD, CALLPROC_FDS):
        New constants.
        (record_kill_process): New arg, the temp name.  All callers changed.
        (delete_temp_file): Now just a simple wrapper around unlink.
        (call_process_kill): New arg, the call_process_fd array.
        Close them all.  Clear synch_process_pid.  Remove the temp file,
        or arrange for it to be removed.
        (call_process_cleanup) [MSDOS]: Arg no longer contains file name;
        that's been moved to synch_process_tempfile.  Caller changed.
        Do not remove the tempfile; that's now call_process_kill's
        responsibility.
        (call_process_cleanup) [!MSDOS]: Do not record unwind-protect for
        call_process_kill; the caller now does that.
        (call_process_cleanup): Do not close the process fd; that's now
        call_process_kill's responsibility.
        (Fcall_process): Implement via new function call_process, which
        has most of the old body of Fcall_process, but with a different API.
        (call_process): New function that does not open or close filefd if
        it is nonnegative.  Record which fds need to be closed, and let
        call_process_kill close (and remove the tempfile, on MSDOS) on error.
        Signal an error if invoked recursively (could be done via a hook).
        Simplify creation of the tempfile in the MSDOS case.
        Don't create the output file until after checking for the executable.
        Report any failure to open /dev/null.
        Don't open /dev/null for writing twice; once is enough.
        Don't create pipe if all output is being discarded or sent to file.
        Don't worry about setting up the coding system or reading from the
        pipe if all output is being discarded.
        Hoist fd_error local into top level, to lessen block nesting.
        Don't record deleted pid here; now done by Fcall_process_region.
        (Fcall_process) [MSDOS]: Report mktemp failure immediately,
        and note its success in synch_process_tempfile.
        Do not leak resources when child_setup fails.
        (Fcall_process) [!MSDOS && !WINDOWSNT]: Remove duplicate assignment
        to child_errno.  Remove unnecessary close of fd0; it's close-on-exec.
        (create_temp_file): Now returns open fd, with an additional
        Lisp_Object * argument to return the name.  All callers changed.
        Do not close the file; rewind it instead, and leave it open for
        the caller.  Do not lock the temp file.  Unwind-protect the file
        and the file-descriptor.
        (Fcall_process_region): If the input is /dev/null, unwind-protect it.
        If an asynchrounous process, record it here, not in call_process.
        (syms_of_callproc) [MSDOS]: Initialize synch_process_tempfile.
        * eval.c (set_unwind_protect): New function.
        * fileio.c (write_region): New function, generalized from the
        old Fwrite_region.  Do not lock temp files.
        (Fwrite_region): Use it.
        * lisp.h (set_unwind_protect, write_region): New decls.
        * process.c: Include <verify.h>.
        (make_process): Mark fds as initially closed.
        (deleted_pid_list): Now a list of pid-filename pairs.
        All uses changed.
        (close_process_fd): New function.
        (SUBPROCESS_STDIN, WRITE_TO_SUBPROCESS, READ_FROM_SUBPROCESS)
        (SUBPROCESS_STDOUT, READ_FROM_EXEC_MONITOR, EXEC_MONITOR_OUTPUT):
        New constants.  Verify that their number matches PROCESS_OPEN_FDS.
        (create_process, create_pty, Fmake_serial_process)
        (server_accept_connection): Record which fds need to be closed,
        and let deactivate_process close them.
        (Fmake_network_process): Do not discard the unwind-protect
        until it's safe to do so.
        (deactivate_process): Close the fds opened by create_process etc.
        (Fprocess_send_eof): Adjust to new way of recording open fds.
        Report an error if /dev/null can't be opened, instead of aborting.
        * process.h (PROCESS_OPEN_FDS): New constant.
        (struct Lisp_Process): New member open_fds.
        (record_kill_process, record_deleted_pid): Adjust signatures.
        (record_deleted_pid): Move decl here ...
        * syswait.h (record_deleted_pid): ... from here.

2013-08-11  Paul Eggert  <eggert@cs.ucla.edu>

        * decompress.c: Fix bugs with large buffers and weird inputs.
        Tune a bit.  Reindent as per usual Emacs style.
        (BUFFER_SIZE): Remove.
        (Fdecompress_gzipped_region): Do not mishandle input buffers with
        more than UINT_MAX bytes.  Decompress into the gap instead of into
        an auto buffer, as this should avoid copying.  Return nil if
        'inflate' returns Z_NEED_DICT, as we have no dictionary.  Do not
        set immediate_quit; we shouldn't trust zlib code that much.

2013-08-11  Lars Magne Ingebrigtsen  <larsi@gnus.org>

        * decompress.c (Fdecompress_gzipped_region): Respect all zlib
        errors, and really move the gap to where we want it.

        * emacs.c (main): Include decompress.c support.

        Be more careful if selected window shows the buffer other than current,

        * editfns.c (Fsubst_char_in_region, Ftranslate_region_internal)
        (Ftranspose_regions): Use modify_text.

2013-08-05  Stefan Monnier  <monnier@iro.umontreal.ca>

        * lisp.mk (lisp): Add nadvice.elc.

2013-08-05  Dmitry Antipov  <dmantipov@yandex.ru>

        New macro to iterate over live buffers similar to frames.
        * buffer.h (FOR_EACH_LIVE_BUFFER): New macro.
        (Vbuffer_alist, Qpriority, Qbefore_string, Qafter_string):
        Declare buffer-related variables here to offload lisp.h.

        Fix some minor races in hosts lacking mkostemp (Bug#15015).
        * callproc.c (create_temp_file):
        * filelock.c (create_lock_file):
        Assume mkostemp, since it's now provided by Gnulib.

2013-08-04  Eli Zaretskii  <eliz@gnu.org>

        * w32.c (mkostemp): New function.
        (mktemp): Remove, no longer used.  Most of the code reused in
        mkostemp.  (Bug#15015)
        (mktemp): Don't undef.

2013-08-04  Dmitry Antipov  <dmantipov@yandex.ru>

        * dispnew.c (glyph_matrix_count, glyph_pool_count):
        Move under GLYPH_DEBUG and ENABLE_CHECKING.
        (new_glyph_matrix, free_glyph_matrix, new_glyph_pool)
        (free_glyph_pool, check_glyph_memory): Likewise for
        all users.  Adjust comments where appropriate.

2013-08-03  Paul Eggert  <eggert@cs.ucla.edu>

        * composite.h: Minor fixups.
        (composition_registered_p): Rename from COMPOSITION_REGISTERD_P
        to fix a misspelling, and change it to an inline function while
        we're at it (it need not be a macro).  All uses changed.
        (composition_method, composition_valid_p):
        Rewrite to avoid assignments in if-conditions.

2013-08-03  Dmitry Antipov  <dmantipov@yandex.ru>

        Do not use global Lisp_Object in composition macros.
        * composite.h (composition_temp): Remove declaration.

        * composite.c (composition_temp): Remove.
        (run_composition_function, update_compositions)
        (composition_compute_stop_pos, composition_adjust_point)
        (Ffind_composition_internal):
        * coding.c (handle_composition_annotation):
        * xdisp.c (handle_composition_prop, check_point_in_composition):
        Related users changed.

2013-08-03  Dmitry Antipov  <dmantipov@yandex.ru>

        Drop FRAME_PTR typedef.
        * composite.c, font.c, font.h, fontset.c, fontset.h, frame.c, frame.h:
        * ftfont.c, ftxfont.c, gtkutil.c, gtkutil.h, image.c, keyboard.c:

        All related users changed.

2013-08-02  Stefan Monnier  <monnier@iro.umontreal.ca>

        (Fdefault_toplevel_value, Fset_default_toplevel_value): New subrs.
        (syms_of_eval): Export them.
        * data.c (Fdefault_value): Micro cleanup.
        * term.c (init_tty): Use "false".

2013-08-02  Dmitry Antipov  <dmantipov@yandex.ru>

        Fix X GC leak in GTK and raw (no toolkit) X ports.
        * xterm.c (x_free_frame_resources): If white and black relief
        GCs are allocated, always free them here.
        * xfns.c (x_make_gc): Omit redundant initialization.
        * widget.c (create_frame_gcs): Remove the leftover.
        (EmacsFrameDestroy): Do nothing because all GCs are now freed
        in x_free_frame_resources.

2013-08-02  Jan Djärv  <jan.h.d@swipnet.se>

        * nsterm.m (windowWillResize:toSize:): Only change title if

        modifying it.
        (viewDidEndLiveResize): New method.

        * nsterm.h (EmacsView): Add maximizing_resize, put it and old_title
        inside NS_IMPL_COCOA.

2013-08-02  Dmitry Antipov  <dmantipov@yandex.ru>

        * insdel.c (adjust_after_replace, replace_range, del_range_2):
        Do not check whether undo is enabled because record_insert and
        record_delete does that themselves.

2013-08-02  Dmitry Antipov  <dmantipov@yandex.ru>

        * xterm.h (struct x_output) [HAVE_X_I18N]: Remove xic_base_fontname
        member which is not really used any more.
        (FRAME_XIC_BASE_FONTNAME): Remove.
        * xfns.c (xic_free_fontset): Adjust user.
        * xmenu.c (mouse_position_for_popup, x_activate_menubar)
        (update_frame_menubar, set_frame_menubar, free_frame_menubar)
        (create_and_show_popup_menu, xmenu_show, create_and_show_dialog)
        (xdialog_show): Use eassert for debugging check.
        * w32term.c (x_unfocus_frame): Remove unused dummy function.

        Fix prototype.
        * w32uniscribe.c (uniscribe_list, uniscribe_match)
        (uniscribe_list_family): Adjust to match font API change.
        MS-Windows breakage reported by Juanma Barranquero <lekktu@gmail.com>
        at http://lists.gnu.org/archive/html/emacs-devel/2013-08/msg00006.html.

2013-08-01  Dmitry Antipov  <dmantipov@yandex.ru>

        * frame.h (FRAME_MOUSE_UPDATE):
        * nsterm.m (ns_frame_up_to_date): Omit redundant check
        whether hlinfo->mouse_face_mouse_frame is non-NULL.

2013-08-01  Dmitry Antipov  <dmantipov@yandex.ru>

        Avoid redundant Lisp_Object <-> struct frame conversions in font API.
        * font.h (struct font_driver): Change list, match, and list_family
        functions to accept struct frame * as first arg.
        * font.c (font_score, font_compare, font_sort_entities):
        Remove prototypes.
        (font_sort_entities, font_list_entities, font_select_entity)
        (font_find_for_lface, Flist_fonts, Ffont_family_list): Adjust to
        match font API change.
        * xfont.c (xfont_list, xfont_match, xfont_list_family):
        * ftfont.c (ftfont_list, ftfont_match, ftfont_list_family):
        * ftxfont.c (ftxfont_list, ftxfont_match):
        * xftfont.c (xftfont_list, xftfont_match):
        * nsfont.m (nsfont_list, nsfont_match, nsfont_list_family):
        * w32font.c (w32font_list, w32font_match, w32font_list)
        (w32font_list_internal, w32_font_match_internal): Likewise.
        * xfaces.c (Fx_family_fonts): Adjust user.

2013-08-01  Dmitry Antipov  <dmantipov@yandex.ru>

        Do not use pure Xism x_wm_set_icon_position in non-X ports.
        * frame.c (x_set_frame_parameters): Call to x_wm_set_icon_position
        only if HAVE_X_WINDOWS is in use.
        * frame.h (x_set_frame_parameters): Move under HAVE_X_WINDOWS.
        * nsterm.m (x_wm_set_icon_position): Remove no-op.
        * w32term.c (x_wm_set_icon_position): Likewise.
        * w32fns.c (x_icon): Adjust user.

2013-08-01  Dmitry Antipov  <dmantipov@yandex.ru>

        * xterm.c (last_mouse_press_frame): Remove the
        leftover which is not really used any more.
        (handle_one_xevent, syms_of_xterm): Adjust users.
        (x_flush): Call XFlush once per each X display, not frame.
        This is better because this code always unconditionally skips
        non-X frames in Vframe_list and issues the only XFlush if we
        have more than one X frame on the same X display.
        (any_help_event_p, x_draw_glyph_string_background, x_display_ok):
        Use bool for booleans.
        (x_draw_glyph_string_background, cvt_string_to_pixel)
        (cvt_pixel_dtor): Drop unnecessary prototypes.
        * xterm.h (x_display_ok): Adjust prototype.

        * frame.h, msdos.h, w32term.h, xterm.h (x_pixel_width)
        (x_pixel_height): Drop prototypes.
        * msdos.c, nsfns.m, w32fns.c, xfns.c (x_pixel_width)
        (x_pixel_height): Drop implementations.
        * frame.c (Fframe_pixel_height): Use FRAME_PIXEL_HEIGHT
        which should be always valid for window frame.
        (Frame_pixel_width): Likewise with FRAME_PIXEL_WIDTH.
        * w32menu.c (Fx_popup_dialog):
        * xmenu.c (Fx_popup_dialog): Likewise for both.

2013-07-31  Dmitry Antipov  <dmantipov@yandex.ru>

        * frame.c (Fmake_terminal_frame): Use store_in_alist to setup
        frame parameters and call to Fmodify_frame_parameters just once.
        (Fset_frame_height, Fset_frame_width): Mention nil frame in docstring.
        (Fset_frame_size, Fset_frame_position): Use decode_live_frame
        and mention nil frame in docstring.

2013-07-31  Dmitry Antipov  <dmantipov@yandex.ru>

        * frame.c (make_frame, x_set_frame_parameters): Use bool for boolean.
        (x_figure_window_size): Likewise.  Adjust to return long.
        (syms_of_frame): Do not DEFSYM Qterminal_live_p.
        (toplevel): Move Qterminal_live_p to...
        * terminal.c (toplevel): ...here, make it static, and...
        (syms_of_terminal): ...DEFSYM here.
        * frame.h (Qterminal_live_p): Remove declaration.
        (make_frame, x_figure_window_size): Adjust prototype.
        * nsfns.m (Fx_create_frame): Use long for window flags.

2013-07-30  Paul Eggert  <eggert@cs.ucla.edu>

        Fix tempfile bug on platforms lacking mkostemp and mkstemp (Bug#14986).
        * callproc.c (create_temp_file) [! (HAVE_MKOSTEMP || HAVE_MKSTEMP)]:
        Do not assume that emacs_close (INT_MAX) is a no-op.

2013-07-30  Dmitry Antipov  <dmantipov@yandex.ru>

        * xfaces.c (make_face_cache): For struct face_cache, prefer
        xmalloc to xzalloc and so avoid redundant call to memset.
        (Finternal_set_lisp_face_attribute): Fix comment typo and style.

2013-07-30  Dmitry Antipov  <dmantipov@yandex.ru>

        * fringe.c (draw_window_fringes, update_window_fringes)
        (compute_fringe_widths):
        * w32term.c (x_draw_glyph_string):
        * window.c (candidate_window_p, Frecenter):
        * xfaces.c (realize_basic_faces, realize_default_face)
        (Fbitmap_space_p, Finternal_set_lisp_face_attribute)
        (x_update_menu_appearance, face_attr_equal_p, lface_equal_p):
        * xfns.c (x_set_cursor_color, xic_free_xfontset):
        * xmenu.c (Fx_menu_bar_open_internal):
        * xselect.c (x_reply_selection_request, Fx_get_atom_name):
        * xsettings.c (xft_settings_event):
        * xterm.c (x_draw_glyph_string, x_had_errors_p):
        Use bool for booleans.  Adjust style and comments where
        appropriate.
        * dispextern.h (draw_window_fringes, update_window_fringes)
        (compute_fringe_widths):
        * xterm.h (x_had_errors_p): Adjust prototype.

2013-07-30  Dmitry Antipov  <dmantipov@yandex.ru>

        * frame.c (Fmodify_frame_parameters): Always check 2nd arg with
        CHECK_LIST.  Rewrite the loop to avoid useless local variable.

2013-07-29  Dmitry Antipov  <dmantipov@yandex.ru>

        * fns.c (toplevel): Remove comment before Fsafe_length because
        it checks for QUIT.

2013-07-28  Paul Eggert  <eggert@cs.ucla.edu>

        * frame.c (delete_frame): Avoid unnecessary 'this_f' test (Bug#14970).

2013-07-28  Eli Zaretskii  <eliz@gnu.org>

        * w32fns.c (w32_wnd_proc) <WM_IME_STARTCOMPOSITION>: Make sure the
        frame which got the message is still alive, before dereferencing
        its pointer.  (Bug#14970)

        * frame.c (delete_frame): Test "this" frame's minibuffer window to
        be a live window, before using it as such.  (Bug#14970)

2013-07-27  Eli Zaretskii  <eliz@gnu.org>

        * w32term.c (w32_read_socket) <WM_KILLFOCUS>: Call
        w32_detect_focus_change instead of doing part of its job by hand.
        This fixes the problem whereby FOCUS_OUT events were not sent to
        the event queue.

2013-07-26  Eli Zaretskii  <eliz@gnu.org>

        * process.c (Fprocess_list): Doc fix.

        * w32term.c (w32_read_socket) <WM_EMACS_PAINT>: Warn about frame
        being re-exposed only if it didn't ask to become visible.
        <WM_SIZE>: Under SIZE_RESTORED, only set the frame visible if it
        was previously iconified.  (Bug#14841)
        (x_iconify_frame): Mark the frame iconified.

2013-07-26  Paul Eggert  <eggert@cs.ucla.edu>

        Fix minor problems found by static checking.

        (backtrace_eval_unrewind): ';' -> '{}' to pacify GCC.

2013-07-26  Stefan Monnier  <monnier@iro.umontreal.ca>

        * eval.c (set_specpdl_old_value): New function.
        (unbind_to): Minor simplification.
        (get_backtrace_frame): New function.
        (Fbacktrace_frame): Use it.  Add `base' argument.
        (backtrace_eval_unrewind, Fbacktrace_eval): New functions.
        (syms_of_eval): Export backtrace-eval.
        * xterm.c (x_focus_changed): Simplify.

2013-07-25  Paul Eggert  <eggert@cs.ucla.edu>

        * fileio.c (Finsert_file_contents): Avoid double-close (Bug#14936).

2013-07-24  Eli Zaretskii  <eliz@gnu.org>

        * xdisp.c (redisplay_window): Instead of moving point out of
        scroll margin, reject the force_start method, and try scrolling
        instead.  (Bug#14780)

2013-07-24  Ken Brown  <kbrown@cornell.edu>

        * alloc.c (make_save_ptr): Define if HAVE_NTGUI is defined
        (Bug#14944).

2013-07-24  Paul Eggert  <eggert@cs.ucla.edu>

        * eval.c (Fprogn): Do not check that BODY is a proper list.
        This undoes the previous change.  The check slows down the
        interpreter, and is not needed to prevent a crash.  See
        <http://lists.gnu.org/archive/html/emacs-devel/2013-07/msg00693.html>.

2013-07-23  Glenn Morris  <rgm@gnu.org>

        * Makefile.in ($(etc)/DOC, temacs$(EXEEXT)): Ensure etc/ exists.

2013-07-23  Paul Eggert  <eggert@cs.ucla.edu>

        Port to GNU/Linux systems with tinfo but not ncurses.
        * dispnew.c (init_display): Depend on USE_NCURSES, not GNU_LINUX,
        to decide whether ncurses is being used.  Without this change,
        GCC complains about tgetent not being declared, on a system
        that has tinfo installed but ncurses not installed.

        * eval.c (Fprogn): Check that BODY is a proper list.

        Tune UNEVALLED functions by using XCAR instead of Fcar, etc.
        * data.c (Fsetq_default):
        * eval.c (Fif, Fcond, Fprog1, Fsetq, Fquote, Ffunction, Fdefvar)
        (Fdefconst, FletX, Flet, Fwhile, Fcatch, Funwind_protect)
        (Fcondition_case):
        Tune by taking advantage of the fact that ARGS is always a list
        when a function is declared to have UNEVALLED args.

        * emacsgtkfixed.c: Port to GCC 4.6.
        GCC 4.6 complains about -Wunused-local-typedefs, introduced in 4.7.

2013-07-23  Juanma Barranquero  <lekktu@gmail.com>

        * callproc.c (child_setup)[!WINDOWSNT]: Move exec_errno and pid
        here to silence compiler warnings.

2013-07-22  Paul Eggert  <eggert@cs.ucla.edu>

        * sysdep.c (frame) [__FreeBSD__]: #define to freebsd_frame
        when including <sys/user.h>, to prevent Sparc/ARM machine/frame.h
        from messing up Emacs's 'struct frame' (Bug#14923).

2013-07-21  Paul Eggert  <eggert@cs.ucla.edu>

        * alloc.c (make_save_ptr_ptr): Define this function.
        It was inadvertently omitted.  It's needed only if
        HAVE_MENUS && ! (USE_X_TOOLKIT || USE_GTK).

2013-07-21  Jan Djärv  <jan.h.d@swipnet.se>

        * nsterm.m (sendEvent:): Skip mouse moved if no dialog and no Emacs
        frame have focus (Bug#14895).

2013-07-21  Paul Eggert  <eggert@cs.ucla.edu>

        Avoid vfork-related deadlock more cleanly.
        * callproc.c (child_setup): When the child's exec fails, output
        the program name, as that's more useful.  Use O_NONBLOCK to avoid
        deadlock.
        * process.c (create_process_1): Remove; no longer needed.
        (create_process): Remove timer hack; no longer needed, now that
        the child avoids deadlock.

2013-07-20  Glenn Morris  <rgm@gnu.org>

        * image.c (Fimage_flush): Fix doc typo.

2013-07-20  Paul Eggert  <eggert@cs.ucla.edu>

        Fix array bounds violation when pty allocation fails.
        * process.c (PTY_NAME_SIZE): New constant.
        (pty_name): Remove static variable; it's now auto.
        (allocate_pty): Define even if !HAVE_PTYS; that's simpler.
        Take pty_name as an arg rather than using a static variable.
        All callers changed.
        (create_process): Recover pty_flag from process, not from volatile local.
        (create_pty): Stay inside array even when pty allocation fails.
        (Fmake_serial_process): Omit unnecessary initializaiton of pty_flag.

        * lread.c (Fload): Avoid initialization only when lint checking.
        Mention that it's needed only for older GCCs.

2013-07-20  Kenichi Handa  <handa@gnu.org>

        * coding.c (CODING_ISO_FLAG_LEVEL_4): New macro.
        (decode_coding_iso_2022): Check the single-shift area.  (Bug#8522)

2013-07-20  Andreas Schwab  <schwab@linux-m68k.org>

        * lread.c (Fload): Avoid uninitialized warning.

2013-07-19  Paul Eggert  <eggert@cs.ucla.edu>

        Fix some minor file descriptor leaks and related glitches.
        * filelock.c (create_lock_file) [!O_CLOEXEC]: Use fcntl with FD_CLOEXEC.
        (create_lock_file): Use write, not emacs_write.
        * image.c (slurp_file, png_load_body):
        * process.c (Fnetwork_interface_list, Fnetwork_interface_info)
        (server_accept_connection):
        Don't leak an fd on memory allocation failure.
        * image.c (slurp_file): Add a cheap heuristic for growing files.
        * xfaces.c (Fx_load_color_file): Block input around the fopen too,
        as that's what the other routines do.  Maybe input need not be
        blocked at all, but it's better to be consistent.
        Avoid undefined behavior when strlen is zero.

        * alloc.c (staticpro): Avoid buffer overrun on repeated calls.
        (NSTATICS): Now a constant; doesn't need to be a macro.

2013-07-19  Richard Stallman  <rms@gnu.org>

        * coding.c (decode_coding_utf_8): Add simple loop for fast
        processing of ASCII characters.

2013-07-19  Paul Eggert  <eggert@cs.ucla.edu>

        * conf_post.h (RE_TRANSLATE_P) [emacs]: Remove obsolete optimization.

2013-07-19  Eli Zaretskii  <eliz@gnu.org>

        * keyboard.c (kbd_buffer_get_event): Use Display_Info instead of
        unportable 'struct x_display_info'.
        (DISPLAY_LIST_INFO): Delete macro: not needed, since Display_Info
        is a portable type.

2013-07-19  Paul Eggert  <eggert@cs.ucla.edu>

        * sysdep.c [GNU_LINUX]: Fix fd and memory leaks and similar issues.
        (procfs_ttyname): Don't use uninitialized storage if emacs_fopen
        or fscanf fails.
        (system_process_attributes): Prefer plain char to unsigned char
        when either will do.  Clean up properly if interrupted or if
        memory allocations fail.  Don't assume sscanf succeeds.
        Remove no-longer-needed workaround to stop GCC from whining.
        Read command-line once, instead of multiple times.  Check read status a
        bit more carefully.

        Fix obscure porting bug with varargs functions.
        The code assumed that int is treated like ptrdiff_t in a vararg
        function, which is not a portable assumption.  There was a similar
        -- though these days less likely -- porting problem with various
        assumptions that pointers of different types all smell the same as
        far as vararg functions is conserved.  To make this problem less
        likely in the future, redo the API to use varargs functions.
        * alloc.c (make_save_value): Remove this vararg function.
        All uses changed to ...
        (make_save_int_int_int, make_save_obj_obj_obj_obj)
        (make_save_ptr_int, make_save_funcptr_ptr_obj, make_save_memory):
        New functions.
        (make_save_ptr): Rename from make_save_pointer, for consistency with
        the above.  Define only on platforms that need it.  All uses changed.

2013-07-18  Paul Eggert  <eggert@cs.ucla.edu>

        * keyboard.c: Try to fix typos in previous change.
        (DISPLAY_LIST_INFO): New macro.
        (kbd_buffer_get_event): Do not access members that are not present
        in X11.  Revert inadvertent change of "!=" to "=".

2013-07-18  Juanma Barranquero  <lekktu@gmail.com>

        * keyboard.c (kbd_buffer_get_event):
        * w32term.c (x_focus_changed): Port FOCUS_(IN|OUT)_EVENT changes to W32.
        Followup to 2013-07-16T11:41:06Z!jan.h.d@swipnet.se.

2013-07-18  Paul Eggert  <eggert@cs.ucla.edu>

        * filelock.c: Fix unlikely file descriptor leaks.
        (get_boot_time_1): Rework to avoid using emacs_open.
        This doesn't actually fix a leak, but is better anyway.
        (read_lock_data): Use read, not emacs_read.

        * doc.c: Fix minor memory and file descriptor leaks.
        * doc.c (get_doc_string): Fix memory leak when doc file absent.
        (get_doc_string, Fsnarf_documentation):
        Fix file descriptor leak on error.

        * term.c: Fix minor fdopen-related file descriptor leaks.
        * term.c (Fresume_tty) [!MSDOS]: Close fd if fdopen (fd) fails.
        (init_tty) [!DOS_NT]: Likewise.  Also close fd if isatty (fd) fails.

        * charset.c: Fix file descriptor leaks and errno issues.
        Include <errno.h>.
        (load_charset_map_from_file): Don't leak file descriptor on error.
        Use plain record_xmalloc since the allocation is larger than
        MAX_ALLOCA; that's simpler here.  Simplify test for exhaustion
        of entries.
        * eval.c (record_unwind_protect_nothing):
        * fileio.c (fclose_unwind):
        New functions.
        * lread.c (load_unwind): Remove.  All uses replaced by fclose_unwind.
        The replacement doesn't block input, but that no longer seems
        necessary.

2013-07-17  Paul Eggert  <eggert@cs.ucla.edu>

        * lread.c: Fix file descriptor leaks and errno issues.
        (Fload): Close some races that leaked fds or streams when 'load'
        was interrupted.
        (Fload, openp): Report error number of last nontrivial failure to open.
        ENOENT counts as trivial.
        * eval.c (do_nothing, clear_unwind_protect, set_unwind_protect_ptr):
        New functions.
        * fileio.c (close_file_unwind): No need to test whether FD is nonnegative,
        now that the function is always called with a nonnegative arg.
        * lisp.h (set_unwind_protect_ptr, set_unwind_protect_int): Remove.
        All uses replaced with ...
        (clear_unwind_protect, set_unwind_protect_ptr): New decls.

        A few more minor file errno-reporting bugs.
        * callproc.c (Fcall_process):
        * doc.c (Fsnarf_documentation):
        * fileio.c (Frename_file, Fadd_name_to_file, Fmake_symbolic_link):
        * process.c (set_socket_option):
        Don't let a constructor trash errno.
        * doc.c: Include <errno.h>.

2013-07-16  Juanma Barranquero  <lekktu@gmail.com>

        * w32fns.c (unwind_create_tip_frame): Fix declaration.

2013-07-16  Paul Eggert  <eggert@cs.ucla.edu>

        Fix w32 bug with call-process-region (Bug#14885).
        * callproc.c (Fcall_process_region): Pass nil, not "/dev/null",
        to Fcall_process when the input is empty.  This simplifies the
        code a bit.  It makes no difference on POSIXish platforms but
        apparently it fixes a bug on w32.

        Fix bug where insert-file-contents closes a file twice (Bug#14839).
        * fileio.c (close_file_unwind): Don't close if FD is negative;
        this can happen when unwinding a zapped file descriptor.
        (Finsert_file_contents): Unwind-protect the fd before the point marker,
        in case Emacs runs out of memory between the two unwind-protects.
        Don't trash errno when closing FD.
        Zap the FD in the specpdl when closing it, instead of deferring
        the removal of the unwind-protect; this fixes a bug where a child
        function unwinds the stack past us.

        New unwind-protect flavors to better type-check C callbacks.
        This also lessens the need to write wrappers for callbacks,
        and the need for make_save_pointer.
        * alloc.c (free_save_value):
        * atimer.c (run_all_atimers):
        Now extern.
        * alloc.c (safe_alloca_unwind):
        * atimer.c (unwind_stop_other_atimers):
        * keyboard.c (cancel_hourglass_unwind) [HAVE_WINDOW_SYSTEM]:
        * menu.c (cleanup_popup_menu) [HAVE_NS]:
        * minibuf.c (choose_minibuf_frame_1):

        * xdisp.c (pop_message_unwind):
        * xselect.c (queue_selection_requests_unwind):
        Remove no-longer-needed wrapper.  All uses replaced by the wrappee.
        * alloc.c (record_xmalloc):
        Prefer record_unwind_protect_ptr to record_unwind_protect with
        make_save_pointer.
        * alloc.c (Fgarbage_collect):
        Prefer record_unwind_protect_void to passing a dummy.
        * buffer.c (restore_buffer):
        * window.c (restore_window_configuration):
        * xfns.c, w32fns.c (do_unwind_create_frame)
        New wrapper.  All record-unwind uses of wrappee changed.
        * buffer.c (set_buffer_if_live):
        * callproc.c (call_process_cleanup, delete_temp_file):
        * coding.c (code_conversion_restore):
        * dired.c (directory_files_internal_w32_unwind) [WINDOWSNT]:
        * editfns.c (save_excursion_restore)

        (fast_set_selected_frame):
        * xfns.c, w32fns.c (unwind_create_tip_frame):
        Return void, not a dummy Lisp_Object.  All uses changed.
        * buffer.h (set_buffer_if_live): Move decl here from lisp.h.
        * callproc.c (call_process_kill):
        * fileio.c (restore_point_unwind, decide_coding_unwind)
        (build_annotations_unwind):

        * xfns.c (clean_up_dialog):
        * xselect.c (x_selection_request_lisp_error, x_catch_errors_unwind):
        Accept no args and return void, instead of accepting and returning
        a dummy Lisp_Object.  All uses changed.
        * cygw32.c (fchdir_unwind):
        * fileio.c (close_file_unwind):
        * keyboard.c (restore_kboard_configuration):
        * lread.c (readevalllop_1):
        * process.c (wait_reading_process_output_unwind):
        Accept int and return void, rather than accepting an Emacs integer
        and returning a dummy object.  In some cases this fixes an
        unlikely bug when the corresponding int is outside Emacs integer
        range.  All uses changed.
        * dired.c (directory_files_internal_unwind):
        * fileio.c (do_auto_save_unwind):
        * gtkutil.c (pop_down_dialog):
        * insdel.c (reset_var_on_error):
        * lread.c (load_unwind):
        * xfns.c (clean_up_file_dialog):
        * xmenu.c, nsmenu.m (pop_down_menu):
        * xmenu.c (cleanup_widget_value_tree):
        * xselect.c (wait_for_property_change_unwind):
        Accept pointer and return void, rather than accepting an Emacs
        save value encapsulating the pointer and returning a dummy object.
        All uses changed.
        * editfns.c (Fformat): Update the saved pointer directly via
        set_unwind_protect_ptr rather than indirectly via make_save_pointer.
        * eval.c (specpdl_func): Remove.  All uses replaced by definiens.
        (unwind_body): New function.
        (record_unwind_protect): First arg is now a function returning void,
        not a dummy Lisp_Object.
        (record_unwind_protect_ptr, record_unwind_protect_int)
        (record_unwind_protect_void): New functions.
        (unbind_to): Support SPECPDL_UNWIND_PTR etc.
        * fileio.c (struct auto_save_unwind): New type.
        (do_auto_save_unwind): Use it.
        (do_auto_save_unwind_1): Remove; subsumed by new do_auto_save_unwind.
        * insdel.c (struct rvoe_arg): New type.
        (reset_var_on_error): Use it.
        * lisp.h (SPECPDL_UNWIND_PTR, SPECPDL_UNWIND_INT, SPECPDL_UNWIND_VOID):
        New constants.
        (specbinding_func): Remove; there are now several such functions.
        (union specbinding): New members unwind_ptr, unwind_int, unwind_void.
        (set_unwind_protect_ptr): New function.
        * xselect.c: Remove unnecessary forward decls, to simplify maintenance.

        Be simpler and more consistent about reporting I/O errors.
        * fileio.c (Fcopy_file, Finsert_file_contents, Fwrite_region):
        Say "Read error" and "Write error", rather than "I/O error", or
        "IO error reading", or "IO error writing", when a read or write
        error occurs.
        * process.c (Fmake_network_process, wait_reading_process_output)
        (send_process, Fprocess_send_eof, wait_reading_process_output):
        Capitalize diagnostics consistently.  Put "failed foo" at the
        start of the diagnostic, so that we don't capitalize the
        function name "foo".  Consistently say "failed" for such
        diagnostics.
        * sysdep.c, w32.c (serial_open): Now accepts Lisp string, not C string.
        All callers changed.  This is so it can use report_file_error.
        * sysdep.c (serial_open, serial_configure): Capitalize I/O
        diagnostics consistently as above.

        * fileio.c (report_file_errno): Fix errno reporting bug.
        If the file name is neither null nor a pair, package it up as a
        singleton list.  All callers changed, both to this function and to
        report_file_error.  This fixes a bug where the memory allocator
        invoked by list1 set errno so that the immediately following
        report_file_error reported the wrong errno value.

        Fix minor problems found by --enable-gcc-warnings.
        * frame.c (Fhandle_focus_in, Fhandle_focus_out): Return a value.
        * keyboard.c (kbd_buffer_get_event): Remove unused local.

2013-07-16  Jan Djärv  <jan.h.d@swipnet.se>

        * xterm.c (x_focus_changed): Always generate FOCUS_IN_EVENT.
        Set event->arg to Qt if switch-event shall be generated.
        Generate FOCUS_OUT_EVENT for FocusOut if this is the focused frame.

        * termhooks.h (enum event_kind): Add FOCUS_OUT_EVENT.

        * nsterm.m (windowDidResignKey): If this is the focused frame, generate
        FOCUS_OUT_EVENT.

        * keyboard.c (Qfocus_in, Qfocus_out): New static objects.
        (make_lispy_focus_in, make_lispy_focus_out): Declare and define.
        (kbd_buffer_get_event): For FOCUS_IN, make a focus_in event if no
        switch frame event is made.  Check ! NILP (event->arg) if X11 (moved
        from xterm.c).  Make focus_out event for FOCUS_OUT_EVENT if NS or X11
        and there is a focused frame.
        (head_table): Add focus-in and focus-out.
        (keys_of_keyboard): Add focus-in and focus-out to Vspecial_event_map,
        bind to handle-focus-in/out.

        * frame.c (Fhandle_focus_in, Fhandle_focus_out): New functions.
        (Fhandle_switch_frame): Call Fhandle_focus_in.
        (syms_of_frame): defsubr handle-focus-in/out.

2013-07-16  Paul Eggert  <eggert@cs.ucla.edu>

        Fix porting bug to older POSIXish platforms (Bug#14862).
        * sysdep.c (emacs_pipe): New function, that implements
        pipe2 (fd, O_CLOEXEC) even on hosts that lack O_CLOEXEC.
        This should port better to CentOS 5 and to Mac OS X 10.6.
        All calls to pipe2 changed.

        Prefer list1 (X) to Fcons (X, Qnil) when building lists.
        This makes the code easier to read and the executable a bit smaller.
        Do not replace all calls to Fcons that happen to create lists,
        just calls that are intended to create lists.  For example, when
        creating an alist that maps FOO to nil, use list1 (Fcons (FOO, Qnil))
        rather than list1 (list1 (FOO)) or Fcons (Fcons (FOO, Qnil), Qnil).
        Similarly for list2 through list5.

        * xdisp.c (redisplay_tool_bar, store_mode_line_string)
        (Fformat_mode_line, syms_of_xdisp):
        * xfaces.c (set_font_frame_param)
        (Finternal_lisp_face_attribute_values)

        (menu_help_callback, xmenu_show):
        * xml.c (make_dom):
        * xterm.c (set_wm_state):
        Prefer list1 (FOO) to Fcons (FOO, Qnil) when creating a list,
        and similarly for list2 through list5.

2013-07-15  Paul Eggert  <eggert@cs.ucla.edu>

        * callproc.c (Fcall_process_region): Fix minor race and tune.
        (create_temp_file): New function, with the temp-file-creation part
        of the old Fcall_process_region.  Use Fcopy_sequence to create the
        temp file name, rather than alloca + build_string, for simplicity.
        Don't bother to block input around the temp file creation;
        shouldn't be needed.  Simplify use of mktemp.
        Use record_unwind_protect immediately after creating the temp file;
        this closes an unlikely race where the temp file was not removed.
        Use memcpy rather than an open-coded loop.
        (Fcall_process_region): Use the new function.  If the input is
        empty, redirect from /dev/null rather than from a newly created
        empty temp file; this avoids unnecessary file system traffic.

2013-07-14  Paul Eggert  <eggert@cs.ucla.edu>

        * filelock.c (create_lock_file) [!HAVE_MKOSTEMP && !HAVE_MKSTEMP]:
        Simplify by making this case like the other two.  This is a bit
        slower on obsolete hosts, but the extra complexity isn't worth it.

        * callproc.c (child_setup, relocate_fd) [!DOS_NT]:
        * process.c (create_process) [!DOS_NT]:
        Remove now-unnecessary calls to emacs_close.

2013-07-13  Eli Zaretskii  <eliz@gnu.org>

        * w32term.c (x_draw_hollow_cursor): Delete the brush object when
        returning early.  (Bug#14850)

        * coding.c (syms_of_coding): Set up inhibit-null-byte-detection
        and inhibit-iso-escape-detection attributes of 'undecided'.
        (Bug#14822)

2013-07-13  Paul Eggert  <eggert@cs.ucla.edu>

        * deps.mk (sysdep.o): Remove dependency on ../lib/ignore-value.h.
        Reported by Herbert J. Skuhra in
        <http://lists.gnu.org/archive/html/emacs-devel/2013-07/msg00455.html>.

        Don't lose top specpdl entry when memory is exhausted.
        * eval.c (grow_specpdl): Increment specpdl top by 1 and check for
        specpdl overflow here, to simplify callers; all callers changed.
        Always reserve an unused entry at the stack top; this avoids
        losing the top entry's information when memory is exhausted.

2013-07-12  Paul Eggert  <eggert@cs.ucla.edu>

        Clean up errno reporting and fix some errno-reporting bugs.
        * callproc.c (Fcall_process):
        * fileio.c (Fcopy_file, Finsert_file_contents, Fwrite_region):
        * process.c (create_process, Fmake_network_process):
        * unexaix.c (report_error):
        * unexcoff.c (report_error):
        Be more careful about reporting the errno of failed operations.
        The code previously reported the wrong errno sometimes.
        Also, prefer report_file_errno to setting errno + report_file_error.
        (Fcall_process): Look at openp return value rather than at path,
        as that's a bit faster and clearer when there's a numeric predicate.
        * fileio.c (report_file_errno): New function, with most of the
        old contents of report_file_error.
        (report_file_error): Use it.
        (Ffile_exists_p, Ffile_accessible_directory_p):
        Set errno to 0 when it is junk.
        * fileio.c (Faccess_file):
        * image.c (x_create_bitmap_from_file):
        Use faccessat rather than opening the file, to avoid the hassle of
        having a file descriptor open.
        * lisp.h (report_file_errno): New decl.
        * lread.c (Flocate_file_internal): File descriptor 0 is valid, too.

        Minor EBADF fixes.
        * process.c (create_process, wait_reading_process_output) [AIX]:
        Remove obsolete SIGHUP-related  code, as Emacs no longer disables
        SIGHUP, so EBADF is no longer acceptable here (it wouldn't work in
        a multithreaded environment anyway).
        * sysdep.c (emacs_close): It's not dangerous to invoke emacs_close (-1).

2013-07-12  Andreas Schwab  <schwab@linux-m68k.org>

        * image.c (x_find_image_file): Don't close a remote file handle.

2013-07-12  Paul Eggert  <eggert@cs.ucla.edu>

        Fix races with threads and file descriptors.
        * callproc.c (Fcall_process_region):
        * dired.c (open_directory):
        * emacs.c (main, Fdaemon_initialized):
        * image.c (x_find_image_file):
        * inotify.c (Finotify_rm_watch):
        * lread.c (Flocate_file_internal):
        * process.c (Fnetwork_interface_list, Fnetwork_interface_info):
        * term.c (term_mouse_moveto, init_tty):
        * termcap.c (tgetent):
        * unexaix.c, unexcoff.c (report_error, report_error_1, adjust_lnnoptrs)
        * unexaix.c, unexcoff.c, unexcw.c, unexelf.c (unexec):
        * unexhp9k800.c, unexmacosx.c (unexec):
        * callproc.c (Fcall_process_region):
        Use emacs_close, not close.
        * sysdep.c (POSIX_CLOSE_RESTART, posix_close) [!POSIX_CLOSE_RESTART]:
        New macro and function, which emulates the POSIX_CLOSE_RESTART macro
        and posix_close function on current platforms (which all lack them).
        (emacs_close): Use it.  This should fix the races on GNU/Linux and
        on AIX and on future platforms that support POSIX_CLOSE_RESTART,
        and it should avoid closing random victim file descriptors on
        other platforms.

2013-07-11  Paul Eggert  <eggert@cs.ucla.edu>

        * inotify.c (uninitialized): Remove.  All uses replaced by -1.
        (Finotify_add_watch): Simplify, since -1 means uninitialized now.
        Touch up doc a bit.

        * eval.c (backtrace_function, backtrace_args): Now EXTERNALLY_VISIBLE.
        This is for .gdbinit xbacktrace.

        * sysdep.c, term.c, termcap.c, terminal.c: Integer-related minor fixes.
        * sysdep.c (emacs_get_tty): Return void, since nobody uses the value.
        (emacs_set_tty): Now static.
        * sysdep.c (emacs_set_tty, tabs_safe_p, emacs_close):
        * term.c (tty_capable_p, tty_default_color_capabilities)
        (get_tty_terminal, term_mouse_movement)
        (handle_one_term_event, init_tty, maybe_fatal):
        * termcap.c (tgetst1, struct termcap_buffer, valid_filename_p)
        (tgetent, scan_file, name_match, compare_contin):
        * terminal.c (get_terminal):
        Use bool for boolean.
        * sysdep.c (init_system_name): Don't overflow stack on huge hostname.
        Prefer char to unsigned char if either will do.
        * term.c (OUTPUT, turn_on_face): Omit unnecessary casts to int.
        (tty_write_glyphs): Prefer int to unsigned.
        (produce_glyphless_glyph): Remove 2nd (unused) int arg.
        All callers changed.
        * termcap.c (tprint, main) [TEST]: Remove non-working test.

2013-07-10  Paul Eggert  <eggert@cs.ucla.edu>

        Port to C89.
        * bytecode.c (BYTE_CODE_THREADED): Do not define if __STRICT_ANSI__.
        (B__dummy__): New dummy symbol, to pacify C89.
        * dbusbind.c (XD_DEBUG_MESSAGE): Omit debugging on C89 hosts, since
        they can't grok varargs macros.
        * dispnew.c (add_window_display_history)
        (add_frame_display_history):
        * print.c (print_object):
        * xdisp.c (debug_method_add):
        Use %p printf format only for void pointers.
        * emacs.c (usage_message): New constant, replacing ...
        (USAGE1, USAGE2, USAGE3): Remove; they were too long for C89.
        (main): Adjust to usage reorg.
        * fns.c (syms_of_fns):
        * profiler.c (syms_of_profiler):
        Don't use non-constant struct initializers.
        * gnutls.h (gnutls_initstage_t):
        * lisp.h (enum Lisp_Fwd_Type):
        * lread.c (lisp_file_lexically_bound_p):
        * xsettings.c (anonymous enum):
        Remove trailing comma.
        * xsettings.c (apply_xft_settings): Use %f, not %lf; %lf is a C99ism.
        * lisp.h (ENUM_BF): Use unsigned if pedantic.
        (DEFUN_FUNCTION_INIT): New macro, that falls back on a cast if pre-C99.
        (DEFUN): Use it.
        * regex.c (const_re_char): New type, to pacify strict C89.
        All uses of 'const re_char' replaced to use it.
        * regex.h (_Restrict_): Rename from __restrict, to avoid clash
        with glibc when strict C89.  This change is imported from gnulib.
        All uses changed.
        (_Restrict_arr_): Rename from __restrict_arr, similarly.
        * sysdep.c (time_from_jiffies) [!HAVE_LONG_LONG_INT]:
        Omit GNU_LINUX implementation, since it requires long long.
        * xterm.c (x_draw_underwave):
        Do not assume the traditional order of struct's members.
        (x_term_init): Rewrite to avoid the need for non-constant structure
        initializers.

        Syntax cleanup, mostly replacing macros with functions.
        This removes the need for the syntax_temp hack.
        * search.c: Include syntax.h after buffer.h, since syntax.h uses BVAR.
        * syntax.c (SYNTAX_INLINE): New macro.
        (SYNTAX_FLAGS_COMSTART_FIRST, SYNTAX_FLAGS_COMSTART_SECOND)
        (SYNTAX_FLAGS_COMEND_FIRST, SYNTAX_FLAGS_COMEND_SECOND)
        (SYNTAX_FLAGS_PREFIX, SYNTAX_FLAGS_COMMENT_STYLEB)
        (SYNTAX_FLAGS_COMMENT_STYLEC, SYNTAX_FLAGS_COMMENT_STYLEC2)
        (SYNTAX_FLAGS_COMMENT_NESTED, SYNTAX_FLAGS_COMMENT_STYLE)
        (SYNTAX_COMEND_FIRST): Now functions, not macros.
        (ST_COMMENT_STYLE, ST_STRING_STYLE, INTERVALS_AT_ONCE):
        Now constants, not macros.
        (syntax_temp) [!__GNUC__]: Remove.
        (SYNTAX_PREFIX): Remove; all uses replaced by syntax_prefix_flag_p.
        (syntax_prefix_flag_p): Move implementation of SYNTAX_PREFIX here.
        (SET_RAW_SYNTAX_ENTRY, SET_RAW_SYNTAX_ENTRY_RANGE, SYNTAX_MATCH)
        (SETUP_SYNTAX_TABLE, SETUP_SYNTAX_TABLE_FOR_OBJECT):
        Move here from syntax.h; now functions, not macros.  Except for the
        last function, these are static since only syntax.c uses them.
        (syntax_multibyte): Rename from SYNTAX_WITH_MULTIBYTE_CHECK.
        All uses changed.  Now a function, not a macro; use this fact
        to simplify the code.
        (scan_lists, scan_sexps_forward): Remove workarounds for ancient
        compiler bugs; no longer relevant.
        * syntax.h: Use INLINE_HEADER_BEGIN, INLINE_HEADER_END.
        (SYNTAX_INLINE): New macro.
        (struct gl_state_s, gl_state): Move earlier, so that it's in scope
        for the new functions.  Use bool for boolean member.
        (SYNTAX_ENTRY, SYNTAX, SYNTAX_WITH_FLAGS, SYNTAX_MATCH)
        (SYNTAX_TABLE_BYTE_TO_CHAR, UPDATE_SYNTAX_TABLE_FORWARD)
        (UPDATE_SYNTAX_TABLE_BACKWARD, UPDATE_SYNTAX_TABLE)
        (SETUP_BUFFER_SYNTAX_TABLE):
        Now extern inline functions, not macros.
        (CURRENT_SYNTAX_TABLE, SYNTAX_ENTRY_INT):
        Remove; all uses replaced by implementation.
        (syntax_temp) [!__GNUC__]: Remove decl.
        (SETUP_SYNTAX_TABLE_FOR_OBJECT): New decl.

2013-07-10  Jan Djärv  <jan.h.d@swipnet.se>

        * emacs.c (main): Fix syntax error.

2013-07-10  Paul Eggert  <eggert@cs.ucla.edu>

        Timestamp fixes for undo (Bug#14824).
        * atimer.c (schedule_atimer):
        * fileio.c (Ffile_newer_than_file_p):
        Minor cleanup: use EMACS_TIME_LT so that we can remove EMACS_TIME_GT.
        * buffer.c (buffer-undo-list): Document (t . 0) and (t . -1).
        * fileio.c (Fclear_visited_file_modtime): Move to lisp/files.el.
        (syms_of_fileio): Remove Sclear_visited_file_name.
        (Fvisited_file_modtime): Return -1, not (-1 ...), when the visited
        file doesn't exist; this avoids an ambiguity with negative timestamps.
        (Fset_visited_file_modtime): Accept -1 and 0 as time-list arg.
        * systime.h (make_emacs_time, invalid_emacs_time):
        Don't assume struct timespec layout; POSIX doesn't guarantee it.
        (EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE): Remove.
        * undo.c (record_first_change): Push (visited-file-modtime) onto
        undo list rather than reimplementing it by hand, incorrectly.

2013-07-09  Ken Brown  <kbrown@cornell.edu>

        * sheap.c (STATIC_HEAP_SIZE) [__x86_64__]: Increase to 18MB.

2013-07-09  Juanma Barranquero  <lekktu@gmail.com>

        * makefile.w32-in ($(BLD)/emacs.$(O), $(BLD)/sysdep.$(O)): Update.

2013-07-09  Paul Eggert  <eggert@cs.ucla.edu>

        Handle errno and exit status a bit more carefully.
        * callproc.c (child_setup) [!DOS_NT]: Don't try to stuff an error
        number into an exit status.  Instead, use EXIT_CANCELED.
        (child_setup) [!MSDOS]: Avoid possible deadlock with vfork.
        * callproc.c (relocate_fd):
        * emacs.c (close_output_streams, main):
        * process.c (create_process):
        * sysdep.c (sys_subshell) [!DOS_NT || !WINDOWSNT]:
        Use emacs_perror for simplicity.
        * callproc.c (relocate_fd, main):
        * sysdep.c (sys_subshell):
        Exit with EXIT_CANCELED etc., not 1, when exec setup fails.
        (shut_down_emacs): Use emacs_write, not write.
        * emacs.c, sysdep.c: Don't include <ignore-value.h>.
        * fileio.c (Fcopy_file, e_write):
        * nsterm.m (ns_select):
        * process.c (send_process):
        * sound.c (vox_write):
        Use emacs_write_sig, not emacs_write.
        * lisp.h (emacs_write_sig, emacs_perror): New decls.
        * process.h (EXIT_CANCELED), EXIT_CANNOT_INVOKE, EXIT_ENOENT):
        New constants.
        * sysdep.c (emacs_backtrace): Use emacs_write, not ignore_value
        of write.
        (emacs_full_write): New function.
        (emacs_write): Rewrite to use it.
        (emacswrite_sig, emacs_perror): New functions.
        * xrdb.c (fatal): Don't invoke perror, since errno might be garbage.

2013-07-08  Magnus Henoch  <magnus.henoch@gmail.com>  (tiny change)

        * image.c (imagemagick_load_image): Do not use MagickExportImagePixels
        on NS even if it is present.  Pixmap on NS is a void*.

2013-07-07  Paul Eggert  <eggert@cs.ucla.edu>

        Port to Ubuntu 10 (Bug#14803).
        Problem reported by T.V. Raman.
        * process.c (close_on_exec, accept4, process_socket):
        Define these if !HAVE_ACCEPT4, not if !SOCK_CLOEXEC.

2013-07-07  Eli Zaretskii  <eliz@gnu.org>

        * w32.c (sys_dup): Declare prototype.

        * filelock.c:

2013-07-07  Paul Eggert  <eggert@cs.ucla.edu>

        Make file descriptors close-on-exec when possible (Bug#14803).
        This simplifies Emacs a bit, since it no longer needs to worry
        about closing file descriptors by hand in some cases.
        It also fixes some unlikely races.  Not all such races, as
        libraries often open files internally without setting
        close-on-exec, but it's an improvement.
        * alloc.c (valid_pointer_p) [!WINDOWSNT]:
        * callproc.c (Fcall_process) [!MSDOS]:
        * emacs.c (main) [!DOS_NT]:
        * nsterm.m (ns_term_init):
        * process.c (create_process):
        Use 'pipe2' with O_CLOEXEC instead of 'pipe'.
        * emacs.c (Fcall_process_region) [HAVE_MKOSTEMP]:
        * filelock.c (create_lock_file) [HAVE_MKOSTEMP]:
        Prefer mkostemp with O_CLOEXEC to mkstemp.
        * callproc.c (relocate_fd) [!WINDOWSNT]:
        * emacs.c (main): Use F_DUPFD_CLOEXEC, not plain F_DUPFD.
        No need to use fcntl (..., F_SETFD, FD_CLOEXEC), since we're
        now using pipe2.
        * filelock.c (create_lock_file) [! HAVE_MKOSTEMP]:
        Make the resulting file descriptor close-on-exec.
        * lisp.h, lread.c, process.c (close_load_descs, close_process_descs):
        * lread.c (load_descriptor_list, load_descriptor_unwind):
        Remove; no longer needed.  All uses removed.
        * process.c (SOCK_CLOEXEC): Define to 0 if not supplied by system.
        (close_on_exec, accept4, process_socket) [!SOCK_CLOEXEC]:
        New functions.
        (socket) [!SOCK_CLOEXEC]: Supply a substitute.
        (Fmake_network_process, Fnetwork_interface_list)
        (Fnetwork_interface_info, server_accept_connection):
        Make newly-created socket close-on-exec.
        * sysdep.c (emacs_open, emacs_fopen):
        Make new-created descriptor close-on-exec.
        * w32.c (fcntl): Support F_DUPFD_CLOEXEC well enough for Emacs.
        * w32.c, w32.h (pipe2): Rename from 'pipe', with new flags arg.

2013-07-07  Jan Djärv  <jan.h.d@swipnet.se>

        * nsterm.m (sendEvent:): Propagate keyboard events to modal windows
        for NS_IMPL_GNUSTEP.

2013-07-07  Paul Eggert  <eggert@cs.ucla.edu>

        Fix openp errno handling.
        * callproc.c (Fcall_process): Preserve openp errno around close.
        * lread.c (openp): Set errno when returning -1, as some callers
        expect this.

2013-07-06  Jan Djärv  <jan.h.d@swipnet.se>

        * nsterm.m (sendEvent:): Handle NSAPP_DATA2_RUNFILEDIALOG.

        (ns_run_file_dialog): Declare.

        * nsfns.m: Remove panelOK.
        (ns_fd_data): New.
        (ns_run_file_dialog): New function.
        (Fns_read_file_name): Fill in ns_fd_data, post an event and start the
        event loop, so file dialog is popped up by ns_run_file_dialog, called
        by sendEvent (Bug#14578).
        (EmacsSavePanel, EmacsOpenPanel): Remove ok and cancel methods.

2013-07-06  Eli Zaretskii  <eliz@gnu.org>

        (try_cursor_movement, redisplay_window, try_window)
        (try_window_id): Use it instead of FRAME_LINE_HEIGHT.  (Bug#14771)

        * window.c (window_scroll_pixel_based):
        use default_line_pixel_height.

        * dispextern.h (default_line_pixel_height): Add prototype.

        * frame.c (x_set_line_spacing): Accept a float value for
        line-spacing parameter, per the documentation.

        * data.c (Fmultibyte_string_p): Doc fix.

2013-07-05  Paul Eggert  <eggert@cs.ucla.edu>

        Use emacs_open more consistently when opening files.
        This handles EINTR more consistently now, and makes it easier
        to introduce other uniform changes to file descriptor handling.
        * sysstdio.h: New file.

        plain fopen.
        * dispnew.c, fileio.c, image.c, keyboard.c, lread.c, print.c, sysdep.c:
        * xfaces.c: Include sysstdio.h rather than stdio.h, for emacs_fopen.

        Remove duplicate #include directives.
        * alloc.c [GC_MARK_STACK == GC_USE_GCPROS_CHECK_ZOMBIES]:
        * xfaces.c:
        Don't include stdio.h twice.
        * buffer.c [USE_MMAP_FOR_BUFFERS]:

2013-07-04  Paul Eggert  <eggert@cs.ucla.edu>

        Scale ImageMagick images more carefully.
        * image.c (scale_image_size) [HAVE_IMAGEMAGICK]: New function.
        (compute_image_size): Use it.  Define only if HAVE_IMAGEMAGICK.
        Be more careful about avoiding undefined behavior after
        integer overflow and division by zero.

2013-07-04  YAMAMOTO Mitsuharu  <mituharu@math.s.chiba-u.ac.jp>

        * w32fns.c (Qgeometry, Qworkarea, Qmm_size, Qframes): New variables.
        (syms_of_w32fns): DEFSYM them.
        (MONITORINFOF_PRIMARY, SM_XVIRTUALSCREEN, SM_YVIRTUALSCREEN)
        (CCHDEVICENAME): Define macros if not defined.

        multi-monitor setups in docstrings.
        (Fx_display_mm_height, Fx_display_mm_width): Approximate whole
        screen size by primary monitor's millimeter per pixel.

        (syms_of_w32fns): Defsubr Sw32_display_monitor_attributes_list.

        * w32term.c (SM_CXVIRTUALSCREEN, SM_CYVIRTUALSCREEN): Define macros
        if not defined.
        (x_display_pixel_height, x_display_pixel_width): Use GetSystemMetrics.

2013-07-04  Michael Albinus  <michael.albinus@gmx.de>

        * fileio.c (Qfile_notify_error): New error symbol.

        * gfilenotify.c (Fgfile_add_watch, Fgfile_rm_watch):
        * inotify.c (inotify_callback, symbol_to_inotifymask)
        (Finotify_add_watch, Finotify_rm_watch): Use it.

        (Finotify_add_watch): Adapt docstring.

        * lisp.h (Qfile_notify_error): Declare.

2013-07-04  Paul Eggert  <eggert@cs.ucla.edu>

        Try again to fix FreeBSD bug re multithreaded memory alloc (Bug#14569).
        * emacs.c (main) [HAVE_PTHREAD && !SYSTEM_MALLOC && !DOUG_LEA_MALLOC]:
        Do not clear _malloc_thread_enabled_p, undoing the previous change,
        which did not work (see <http://bugs.gnu.org/14569#307>).
        (main): Do not invoke malloc_enable_thread if (! CANNOT_DUMP
        && (!noninteractive || initialized)).  This attempts to thread
        the needle between the Scylla of FreeBSD and the Charybdis of Cygwin.

2013-07-04  Juanma Barranquero  <lekktu@gmail.com>

        * image.c (x_to_xcolors) [HAVE_NTGUI]: Remove unused var `hdc'.
        (x_build_heuristic_mask) [HAVE_NTGUI]: Remove unused var `frame_dc'.

2013-07-04  Paul Eggert  <eggert@cs.ucla.edu>

        Try to fix FreeBSD bug re multithreaded memory allocation (Bug#14569).
        * emacs.c (main) [HAVE_PTHREAD && !SYSTEM_MALLOC && !DOUG_LEA_MALLOC]:
        Clear _malloc_thread_enabled_p at startup.  Reported by Ashish SHUKLA in
        <http://lists.gnu.org/archive/html/emacs-devel/2013-07/msg00088.html>.

2013-07-02  Paul Eggert  <eggert@cs.ucla.edu>

        * sysdep.c (sys_siglist) [HAVE_DECL___SYS_SIGLIST]:
        Define to __sys_siglist.

2013-07-02  Eli Zaretskii  <eliz@gnu.org>

        * xdisp.c (IT_OVERFLOW_NEWLINE_INTO_FRINGE): Don't disallow
        word-wrap, so that overflow-newline-into-fringe would work in
        visual-line-mode.  (Bug#2749)
        (move_it_in_display_line_to): When the last scanned display
        element fits exactly on the display line, and
        overflow-newline-into-fringe is non-nil, but wrap_it is valid,
        don't return MOVE_NEWLINE_OR_CR, but instead back up to the last
        wrap point and return MOVE_LINE_CONTINUED.  Fixes problems with
        finding buffer position that corresponds to pixel coordinates,
        e.g. in buffer_posn_from_coords.

2013-07-02  Jan Djärv  <jan.h.d@swipnet.se>

        * process.c (handle_child_signal): Call catch_child_signal if
        NS_IMPL_GNUSTEP.

2013-07-02  Paul Eggert  <eggert@cs.ucla.edu>

        Don't convert function pointers to void * and back.
        It isn't portable C, and it's easy enough to avoid.
        * alloc.c: Verify SAVE_FUNCPOINTER bits, too.
        (make_save_value): Add support for SAVE_FUNCPOINTER.
        * keymap.c (map_keymap_char_table_item, map_keymap_internal):
        * print.c (print_object):
        Distinguish function from object pointers.
        * lisp.h (SAVE_FUNCPOINTER): New constant.
        (SAVE_SLOT_BITS): Adjust to it.
        (SAVE_TYPE_FUNCPTR_PTR_OBJ): New constant, replacing
        SAVE_TYPE_PTR_PTR_OBJ.  Change the only use.
        (voidfuncptr): New typedef.
        (struct Lisp_Save_Value): New member data[0].funcpointer.
        (XSAVE_FUNCPOINTER): New function.

        Simplify buildobj processing.
        * Makefile.in (buildobj.h): Make it a sequence of strings each
        followed by comma, rather than a single string.  Put it into a
        .tmp file in case there's an error while generating it.
        (gl-stamp): Use .tmp for temp files.
        (mostlyclean): Clean .tmp files.
        * doc.c (buildobj): Move to just the routine that needs it.
        It's now an array of strings, so processing is simpler.

2013-07-01  Paul Eggert  <eggert@cs.ucla.edu>

        Fix bug re noninteractive multithreaded memory allocation (Bug#14569).
        * emacs.c (malloc_enable_thread): Hoist extern decl to top level.
        (main) [HAVE_PTHREAD && !SYSTEM_MALLOC && !DOUG_LEA_MALLOC]:
        Invoke malloc_enable_thread even when not interactive.
        Problem reported by Ken Brown in <http://bugs.gnu.org/14569#275>.
        * process.c (init_process_emacs) [CYGWIN]: Tickle glib even
        in this case, since the underlying bug has now been fixed.

2013-07-01  Juanma Barranquero  <lekktu@gmail.com>

        * emacs.c (Fkill_emacs): Expand Vauto_save_list_file_name before
        unlinking it (bug#14691).

2013-06-30  Michal Nazarewicz  <mina86@mina86.com>

        * buffer.c (FKill_buffer): Run `kill-buffer-query-functions'
        before checking whether buffer is modified.  This lets
        `kill-buffer-query-functions' cancel killing of the buffer or save
        its content before `kill-buffer' asks user the "Buffer %s
        modified; kill anyway?" question.

2013-06-30  Jan Djärv  <jan.h.d@swipnet.se>

        * nsfns.m (handlePanelKeys): Don't process Command+Function keys.
        Let the super performKeyEquivalent deal with them (Bug#14747).

2013-06-30  Paul Eggert  <eggert@cs.ucla.edu>

        * widget.c (resize_cb): Remove unused local.

        Do not use GTK 3 if it exists but cannot be compiled.
        * xmenu.c (x_menu_wait_for_event) [!USE_GTK]:
        * xterm.c (x_error_handler) [!USE_GTK]:
        Do not use GTK 3.

        * intervals.c (get_local_map): Actually clip POSITION (Bug#14753).

2013-06-30  Eli Zaretskii  <eliz@gnu.org>

        * intervals.c (get_local_map): Instead of aborting, clip POSITION
        to the valid range of values.  (Bug#14753)

        * xdisp.c (Fmove_point_visually): Invalidate the cursor position
        when moving point by using the current glyph matrix.  This avoids
        the need to force redisplay when this function is called in a
        loop.

2013-06-29  Paul Eggert  <eggert@cs.ucla.edu>

        Fix minor problems found by static checking.
        * coding.c (encode_inhibit_flag, inhibit_flag): New functions.
        Redo the latter's body to sidestep GCC parenthesization warnings.
        (setup_coding_system, detect_coding, detect_coding_system): Use them.
        * coding.c (detect_coding, detect_coding_system):
        * coding.h (struct undecided_spec):
        Use bool for boolean.
        * image.c (QCmax_width, QCmax_height): Now static.
        * xdisp.c (Fmove_point_visually): Remove unused local.

2013-06-29  Eli Zaretskii  <eliz@gnu.org>

        * xdisp.c (Fmove_point_visually): New function.

2013-06-28  Kenichi Handa  <handa@gnu.org>

        * coding.h (define_coding_undecided_arg_index): New enum.
        (coding_attr_index): New members
        coding_attr_undecided_inhibit_null_byte_detection,
        coding_attr_undecided_inhibit_iso_escape_detection,
        coding_attr_undecided_prefer_utf_8.
        (undecided_spec): New struct.
        (struct coding_system): New member `undecided' of the member
        `spec'.

        * coding.c (setup_coding_system): Handle CODING->spec.undecided.
        (detect_coding): Likewise.
        (detect_coding_system): Likewise.
        (Fdefine_coding_system_internal): New coding system properties
        :inhibit-null-byte-detection, :inhibit-iso-escape-detection, and
        :prefer-utf-8.
        (syms_of_coding): Adjust for coding_arg_undecided_max.

2013-06-28  Paul Eggert  <eggert@cs.ucla.edu>

        * image.c (x_from_xcolors): Remove unused local.

2013-06-28  YAMAMOTO Mitsuharu  <mituharu@math.s.chiba-u.ac.jp>

        Defer image data transfer between X client and server until actual
        display happens.

        * dispextern.h (struct image) [HAVE_X_WINDOWS]: New members `ximg'
        and `mask_img'.

        * image.c (Destroy_Image): Remove.
        (x_clear_image_1): New arg `flags' instead of 3 bools `pixmap_p',
        `mask_p', and `colors_p'.  All uses changed.
        (x_clear_image_1) [HAVE_X_WINDOWS]: Destroy `ximg' and `mask_img'.
        (CLEAR_IMAGE_PIXMAP, CLEAR_IMAGE_MASK, CLEAR_IMAGE_COLORS):
        New macros for `flags' arg to x_clear_image_1.
        (postprocess_image, xpm_load_image, x_build_heuristic_mask)
        (png_load_body): Use x_clear_image_1 instead of Free_Pixmap.
        (ZPixmap, XGetImage) [HAVE_NS]: Remove.
        (image_get_x_image_or_dc, image_unget_x_image_or_dc)
        (image_get_x_image, image_unget_x_image): New functions or macros.
        (image_background, image_background_transparent, x_to_xcolors)
        (x_build_heuristic_mask): Use image_get_x_image_or_dc instead of
        XGetImage or CreateCompatibleDC.  Use image_unget_x_image_or_dc
        instead of Destroy_Image.
        (image_create_x_image_and_pixmap, image_put_x_image): New functions.
        (xpm_load_image, x_from_xcolors, x_build_heuristic_mask, pbm_load)
        (png_load_body, jpeg_load_body, tiff_load, gif_load)
        (imagemagick_load_image, svg_load_image): Use them instead of
        x_create_x_image_and_pixmap, and x_put_x_image followed by
        x_destroy_x_image, respectively.
        (xpm_load) [HAVE_XPM && !HAVE_NTGUI]: Use XpmReadFileToImage and
        XpmCreateImageFromBuffer instead of XpmReadFileToPixmap and
        XpmCreatePixmapFromBuffer.  Create pixmaps.  Fill background and
        background_transparent fields.
        (image_sync_to_pixmaps) [HAVE_X_WINDOWS]: New function.
        (prepare_image_for_display, x_disable_image) [HAVE_X_WINDOWS]: Use it.

2013-06-27  Paul Eggert  <eggert@cs.ucla.edu>

        Do not tickle glib SIGCHLD handling if Cygwin (Bug#14569).
        This mostly consists of undoing recent changes.
        * callproc.c (Fcall_process):
        * process.c (create_process):
        Do not worry about catching SIGCHLD here, undoing previous change.
        * nsterm.m (ns_term_init): Re-catch SIGCHLD, undoing previous change.
        * process.c, process.h (catch_child_signal):
        No longer extern if !NS_IMPL_GNUSTEP, undoing 06-22 change.
        * process.c (catch_child_handler): Don't worry about being called
        lazily and do not assume caller has blocked SIGCHLD, undoing
        previous change.  Move first-time stuff back to
        init_process_emacs, undoing 06-22 change.  If CYGWIN, do not
        tickle glib, as that causes Cygwin bootstrap to fail.  Do not
        set lib_child_handler if it's already initialized, which may
        help avoid problems on GNUstep.

2013-06-23  Paul Eggert  <eggert@cs.ucla.edu>

        A more-conservative workaround for Cygwin SIGCHLD issues (Bug#14569).
        * callproc.c (Fcall_process):
        * process.c (create_process):
        Make sure SIGCHLD is caught before we fork,
        since Emacs startup no arranges to catch SIGCHLD.
        * process.c (lib_child_handler): Initialize to null, not to
        dummy_handler.
        (catch_child_signal): Allow self to be called lazily.
        Do nothing if it's already been called.
        Assume caller has blocked SIGCHLD (all callers do now).
        * emacs.c (main): Do not catch SIGCHLD here; defer it until
        just before it's really needed.
        * nsterm.m (ns_term_init): No need to re-catch SIGCHLD here,
        since it hasn't been caught yet.

2013-06-23  Lars Magne Ingebrigtsen  <larsi@gnus.org>

        * image.c (compute_image_size): New function to implement
        :max-width and :max-height.
        (imagemagick_load_image): Use it.

2013-06-23  Paul Eggert  <eggert@cs.ucla.edu>

        Try to avoid malloc SEGVs on Cygwin (Bug#14569).
        * callproc.c, process.h (block_child_signal, unblock_child_signal):
        Now extern.
        * emacs.c (main): Catch SIGCHLD just before initializing gfilenotify.
        * process.c (catch_child_signal): Block SIGCHLD while futzing with
        the SIGCHLD handler, since the code is not atomic and (due to glib)
        signals may be arriving now.
        * sysdep.c (init_signals): Do not catch child signals here;
        'main' now does that later, at a safer time.

2013-06-22  Paul Eggert  <eggert@cs.ucla.edu>

        Clean up SIGCHLD handling a bit (Bug#14569).
        * process.c, process.h (catch_child_signal):
        Now always extern, even if !NS_IMPL_GNUSTEP.
        * process.c (catch_child_signal): Move glib tickler here from
        init_process_emacs, so that it's done earlier in Emacs
        initialization.  Also move the noninteractive && !initialized
        check here from init_process_emacs.  This is all a bit cleaner for
        GNUish platforms, and I hope it works around the Cygwin bug.
        * sysdep.c (init_signals): Invoke catch_child_signal here, so
        that glib signal handling is tickled before glib creates threads.

        * process.c (wait_reading_process_output): Avoid int overflow
        when reading more than 2 GiB total from a process.

2013-06-21  Paul Eggert  <eggert@cs.ucla.edu>

        * process.c (create_process): Handle a couple more cases,
        i.e., work even if new_argv and wait_child_setup[i] are cached.
        Use Fcall_process's style for volatile vars.

2013-06-21  Andreas Schwab  <schwab@linux-m68k.org>

        * process.c (create_process): Mark PROCESS volatile.

2013-06-21  Paul Eggert  <eggert@cs.ucla.edu>

        Use C99-style flexible array members if available.
        This avoids some subtle aliasing issues, which typically
        aren't a problem with GCC but may be a problem elsewhere.
        * alloc.c (sdata): New typedef, replacing the old struct sdata.
        It is a struct if GC_CHECK_STRING_BYTES, a union otherwise.
        In either case, it uses a flexible array member rather than
        the old struct hack.  All uses changed.
        (SDATA_NBYTES, sweep_strings) [!GC_CHECK_STRING_BYTES]:
        Adjust to sdata reorganization.
        * alloc.c (VBLOCK_BYTES_MIN, allocate_vectorlike, Fgarbage_collect):
        Use offsetof (struct, flex_array_member), not sizeof (struct), as
        that ports better to pre-C99 non-GCC.
        * chartab.c (Fmake_char_table, make_sub_char_table, copy_char_table):
        Use CHAR_TABLE_STANDARD_SLOTS rather than its definition,
        as the latter has changed.
        * conf_post.h (FLEXIBLE_ARRAY_MEMBER): Move here from w32.c,
        and port better to pre-C99 GCC.
        * image.c (struct xpm_cached_color):
        * lisp.h (struct Lisp_Vector, struct Lisp_Bool_Vector)
        (struct Lisp_Char_Table, struct Lisp_Sub_Char_Table):
        Use FLEXIBLE_ARRAY_MEMBER.
        * lisp.h (string_bytes) [GC_CHECK_STRING_BYTES]:
        Move decl to top level so it gets checked against implementation.
        (CHAR_TABLE_STANDARD_SLOTS): Adjust to struct Lisp_Char_Table change.
        * w32.c (FLEXIBLE_ARRAY_MEMBER): Move to conf_post.h.

2013-06-20  Paul Eggert  <eggert@cs.ucla.edu>

        * syntax.c: Integer cleanups.
        (SYNTAX_FLAGS_COMMENT_STYLEC): Return a boolean, not 0-or-2.
        All uses that need 0-or-2 changed to:
        (SYNTAX_FLAGS_COMMENT_STYLEC2): New macro, with the same semantics
        as the old SYNTAX_FLAGS_COMMENT_STYLEC.
        (struct lisp_parse_state, syntax_prefix_flag_p, update_syntax_table)
        (char_quoted, prev_char_comend_first, back_comment)
        (Finternal_describe_syntax_value, skip_chars, skip_syntaxes)
        (in_classes, forw_comment, scan_lists, scan_sexps_forward):
        Use bool for boolean.
        (update_syntax_table, skip_chars, skip_syntaxes):
        Prefer int to unsigned when either will do.
        (back_comment): Return boolean success flag, like forw_comment,
        instead of positive-or-minus-1 (which might have overflowed int anyway).
        Don't stuff ptrdiff_t into int.
        (syntax_spec_code, syntax_code_spec): Now const.
        (Fmatching_paren, scan_lists, scan_sexps_forward):
        Use enum syntaxcode for syntax code.
        (Fmatching_paren): Check that arg is a character, not just an integer.
        (Fstring_to_syntax): Don't assume 0377 fits in enum syntaxcode.
        (Finternal_describe_syntax_value): Omit no-longer-needed
        comparison to 0.
        (skip_chars): Use char, not unsigned char, when the distinction
        doesn't matter.
        (forw_comment, scan_lists): Prefer A |= B to A = A || B when B's cheap.
        * bytecode.c (exec_byte_code):
        * syntax.c (syntax_spec_code, Fchar_syntax)
        (Finternal_describe_syntax_value, skip_chars, skip_syntaxes)
        (init_syntax_once):
        * syntax.h (SYNTAX_WITH_FLAGS):
        Omit unnecessary casts.

2013-06-20  Eli Zaretskii  <eliz@gnu.org>

        * w32fns.c (w32_wnd_proc): Don't compute the header line and mode
        line dimensions here, to avoid race conditions with the main
        thread.  (Bug#14062, bug#14630, bug#14669)

        * w32term.c (w32_draw_window_cursor): Compute the header line and
        mode line dimensions here.
        <w32_system_caret_window, w32_system_caret_hdr_height>:
        <w32_system_caret_mode_height>: New variables.

        * w32term.h: Declare them.

2013-06-20  Paul Eggert  <eggert@cs.ucla.edu>

        * alloc.c (die): Move "assertion failed" string here ...
        * lisp.h (eassert): ... from here.  Also, suppress evaluation of
        COND when SUPPRESS_CHECKING.  This shrinks the executable text
        size by 0.8% to 2.2% when configured with --enable-checking,
        depending on optimization flags (GCC 4.8.1 x86-64).

        * floatfns.c (Flog10): Move to Lisp (marked obsolete there).

2013-06-20  Rüdiger Sonderfeld  <ruediger@c-plusplus.de>

        * floatfns.c (Flog) [HAVE_LOG2]: Use log2 if available and if the
        base is 2; this is more accurate.

2013-06-19  Juanma Barranquero  <lekktu@gmail.com>

        * sound.c (string_default): Move to !WINDOWSNT section.
        (Fplay_sound_internal) [WINDOWSNT]: Remove i_result to avoid warning.

2013-06-19  Paul Eggert  <eggert@cs.ucla.edu>

        * sound.c: Integer cleanups.
        Remove unnecessary forward decls.
        (struct sound_device): The 'file' member is now a Lisp_Object, not
        a char *, so that we needn't invoke alloca on a huge size.
        (Fplay_sound_internal): Adjust to this.
        (string_default): New function.
        (vox_open, vox_init, alsa_open, alsa_configure, alsa_init):
        Use it to adjust to the struct sound_device change.
        (parse_sound, wav_init, au_init, alsa_init): Use bool for booleans.
        (be2hs) [0]: Remove.

        * syntax.c (skip_chars): Don't use uninitialized storage
        when searching a multibyte buffer for characters that are not in a
        unibyte string that contains non-ASCII characters.

2013-06-18  Jan Djärv  <jan.h.d@swipnet.se>

        * process.c: Include xgselect.h if HAVE_GLIB.  Include glib.h
        if HAVE_GLIB && ! WINDOWSNT (Bug#14654).

2013-06-18  Paul Eggert  <eggert@cs.ucla.edu>

        * conf_post.h: Add comments for INLINE, EXTERN_INLINE, etc.

2013-06-18  Kenichi Handa  <handa@gnu.org>

        * font.c (Ffont_spec): Signal an error for an invalid font name
        (Bug#14648).

2013-06-18  Paul Eggert  <eggert@cs.ucla.edu>

        Porting fixes for merged specpdl and backtrace stacks (Bug#14643).
        In particular this ports to 32-bit sparc Sun cc.
        * eval.c (init_eval_once, grow_specpdl): Allocate a specbinding
        array with a dummy element at specpdl[-1], so that its address can
        be taken portably.
        (unbind_to): Do not copy the binding; not needed, now that we
        copy old_value in the one place where the copy is needed.
        * fileio.c (Fwrite_region): Use ptrdiff_t, not int, for specpdl count.
        * lisp.h (BITS_PER_PTRDIFF_T): Remove; no longer needed.
        (union specbinding): Rename from struct specbinding.  Redo layout
        to avoid the need for 'ptrdiff_t nargs : BITS_PER_PTRDIFF_T - 1;',
        which is not portable.  With Sun C 5.12 32-bit sparc, the
        declaration causes nargs to be an unsigned bitfield, a behavior
        that the C standard allows; but Emacs wants nargs to be signed.
        The overall type is now a union of structures rather than a
        structure of union of structures, and the 'kind' member is now a
        bitfield, so that the overall type doesn't grow.  All uses changed.
        * process.c (Fmake_serial_process): Remove unnecessary initialization.

2013-06-17  Paul Eggert  <eggert@cs.ucla.edu>

        * frame.c (x_report_frame_params): Cast parent_desc to uintptr_t.
        Needed if HAVE_NTGUI.  Reported by Juanma Barranquero.

        * nsfont.m (ns_registry_to_script): Parenthesize while expression.

2013-06-17  Eli Zaretskii  <eliz@gnu.org>

        * w32fns.c (w32_wnd_proc): Don't call WINDOW_HEADER_LINE_HEIGHT
        unless we know that the window w's frame is a frame object.
        Another attempt at solving bug#14062 and bug#14630.

2013-06-17  Lars Magne Ingebrigtsen  <larsi@gnus.org>

        * textprop.c (property_set_type): New enum.
        (add_properties): Allow appending/prepending text properties.
        (add_text_properties_1): Factored out of Fadd_text_properties.
        (Fadd_text_properties): Move all the code into
        add_text_properties_1.
        (Fadd_face_text_property): New function that calls
        add_text_properties_1.

2013-06-17  Paul Eggert  <eggert@cs.ucla.edu>

        Move functions from lisp.h to individual modules when possible.
        From a suggestion by Andreas Schwab in <http://bugs.gnu.org/11935#68>.
        * alloc.c (XFLOAT_INIT, set_symbol_name):
        * buffer.c (CHECK_OVERLAY):
        * chartab.c (CHECK_CHAR_TABLE, set_char_table_ascii)
        (set_char_table_parent):
        * coding.c (CHECK_NATNUM_CAR, CHECK_NATNUM_CDR):
        * data.c (BOOLFWDP, INTFWDP, KBOARD_OBJFWDP, OBJFWDP, XBOOLFWD)
        (XKBOARD_OBJFWD, XINTFWD, XOBJFWD, CHECK_SUBR, set_blv_found)
        (blv_value, set_blv_value, set_blv_where, set_blv_defcell)
        (set_blv_valcell):
        * emacs.c (setlocale) [!HAVE_SETLOCALE]:
        * eval.c (specpdl_symbol, specpdl_old_value, specpdl_where)
        (specpdl_arg, specpdl_func, backtrace_function, backtrace_nargs)
        (backtrace_args, backtrace_debug_on_exit):
        * floatfns.c (CHECK_FLOAT):
        * fns.c (CHECK_HASH_TABLE, CHECK_LIST_END)
        (set_hash_key_and_value, set_hash_next, set_hash_next_slot)
        (set_hash_hash, set_hash_hash_slot, set_hash_index)
        (set_hash_index_slot):
        * keymap.c (CHECK_VECTOR_OR_CHAR_TABLE):
        * marker.c (CHECK_MARKER):
        * textprop.c (CHECK_STRING_OR_BUFFER):
        * window.c (CHECK_WINDOW_CONFIGURATION):
        Move here from lisp.h, and make these functions static rather than
        extern inline.
        * buffer.c (Qoverlayp):
        * data.c (Qsubrp):
        * fns.c (Qhash_table_p):
        * window.c (Qwindow_configuration_p):
        Now static.
        * lisp.h: Remove the abovementioned defns and decls.

        Use functions, not macros, for XINT etc (Bug#11935).
        In lisp.h, prefer functions to function-like macros, and
        constants to object-like macros, when either will do.  This:
         . simplifies use, as there's no more need to worry about
           arguments' side effects being evaluated multiple times.
         . makes the code easier to debug on some platforms.
        However, when using gcc -O0, keep using function-like macros
        for a few critical operations, for performance reasons.
        This sort of thing isn't needed with gcc -Og, but -Og
        is a GCC 4.8 feature and isn't widely-enough available yet.
        * alloc.c (gdb_make_enums_visible) [USE_LSB_TAG]:
        Remove enum lsb_bits; no longer needed.
        (allocate_misc, free_misc): Don't use XMISCTYPE as an lvalue.
        * buffer.c (Qoverlap):
        * data.c (Qsubrp):
        * fns.c (Qhash_table_p):
        Now extern, so lisp.h can use these symbols.
        * dispextern.h: Include character.h, for MAX_CHAR etc.
        (GLYPH, GLYPH_CHAR, GLYPH_FACE, SET_GLYPH_CHAR, SET_GLYPH_FACE)
        (SET_GLYPH, GLYPH_CODE_CHAR, GLYPH_CODE_FACE)
        (SET_GLYPH_FROM_GLYPH_CODE, GLYPH_MODE_LINE_FACE, GLYPH_CHAR_VALID_P)
        (GLYPH_CODE_P): Move here from lisp.h.
        (GLYPH_CHAR, GLYPH_FACE, GLYPH_CODE_CHAR, GLYPH_CODE_FACE)
        (GLYPH_CHAR_VALID_P, GLYPH_CODE_P): Now functions, not macros.
        (GLYPH_MODE_LINE_FACE): Now enums, not macros.
        * eval.c (Fautoload): Cast XUNTAG output to intptr_t, since
        XUNTAG now returns void *.
        * lisp.h (lisp_h_XLI, lisp_h_XIL, lisp_h_CHECK_LIST_CONS)
        (lisp_h_CHECK_NUMBER CHECK_SYMBOL, lisp_h_CHECK_TYPE)

        (lisp_h_XPNTR, lisp_h_XSYMBOL):
        New macros, renamed from their sans-lisp_h_ counterparts.
        (XLI, XIL, CHECK_LIST_CONS, CHECK_NUMBER CHECK_SYMBOL)
        (CHECK_TYPE, CONSP, EQ, FLOATP, INTEGERP, MARKERP)

        (VECTORLIKEP, XCAR, XCDR, XCONS, XHASH, XPNTR, XSYMBOL):
        If compiling via GCC without optimization, define these as macros
        in addition to inline functions.
        To disable this, compile with -DINLINING=0.
        (LISP_MACRO_DEFUN, LISP_MACRO_DEFUN_VOID): New macros.
        (check_cons_list) [!GC_CHECK_CONS_LIST]: Likewise.
        (make_number, XFASTINT, XINT, XTYPE, XUNTAG): Likewise, but
        hand-optimize only in the USE_LSB_TAG case, as GNUish hosts do that.
        (INTMASK, VALMASK): Now macros, since static values cannot be
        accessed from extern inline functions.
        (VALMASK): Also a constant, for benefit of old GDB.
        (LISP_INT_TAG_P): Remove; no longer needed as the only caller
        is INTEGERP, which can fold it in.
        (XLI, XIL, XHASH, XTYPE, XINT, XFASTINT, XUINT)

        Now functions.
        (check_cons_list) [!GC_CHECK_CONS_LIST]: New empty function.
        (LISP_MAKE_RVALUE, TYPEMASK): Remove; no longer needed.
        (VALMASK): Define in one place rather than in two, merging the
        USE_LSB_TAG parts; this is simpler.
        (aref_addr, gc_aset, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM)
        (max, min, struct Lisp_String, UNSIGNED_CMP, ASCII_CHAR_P):
        Move up, to avoid use before definition.
        Also include "globals.h" earlier, for the same reason.
        (make_natnum): New function.
        (XUNTAG): Now returns void *, not intptr_t, as this means fewer casts.
        (union Lisp_Fwd, BOOLFWDP, BOOL_VECTOR_P, BUFFER_OBJFWDP, BUFFERP)

        (XCAR_AS_LVALUE, XCDR_AS_LVALUE): Remove these macros, replacing with ...

        * window.c (Qwindow_configuration_p): Now extern,
        so window.h can use it.
        * window.h (Qwindowp): Move decl back to lisp.h.

2013-06-15  Eli Zaretskii  <eliz@gnu.org>

        * xdisp.c (Fline_pixel_height): New function, required for solving
        bug #14567.

2013-06-15  Paul Eggert  <eggert@cs.ucla.edu>

        * fns.c (Fcopy_sequence): Simplify XTYPE calculation.

2013-06-12  Xue Fuqiao  <xfq.free@gmail.com>

        * fileio.c (expand_file_name): Doc fix.

2013-06-11  Paul Eggert  <eggert@cs.ucla.edu>

        Tickle glib by waiting for Emacs itself, not for process 0 (Bug#14569).
        * process.c (init_process_emacs) [HAVE_GLIB && !WINDOWSNT]:
        Wait for self, not for 0.  This can't hurt on GNU or similar
        system, and may help with Cygwin.

        * keyboard.c: Don't use PROP (...) as an lvalue.
        (parse_tool_bar_item) [!USE_GTK && !HAVE_NS]:
        Use set_prop (A, B), not PROP (A) = B.

2013-06-10  Eli Zaretskii  <eliz@gnu.org>

        * xdisp.c (get_it_property): Use it->window instead of generating
        a Lisp object from it->w.

2013-06-09  Eli Zaretskii  <eliz@gnu.org>

        * xdisp.c (get_it_property): If it->object is a buffer, pass to
        get-char-property the window that is being rendered, instead of
        the buffer, to support window-specific overlays.  (Bug#14575)

        don't insist on being invoked on a highlighted tool-bar button.
        Avoids losing tool-bar functionality when mouse-highlight is nil.
        (note_tool_bar_highlight, note_mode_line_or_margin_highlight):
        Don't highlight when mouse-highlight is nil.
        (note_mouse_highlight): When mouse-highlight is nil, don't return
        right away; instead, run tool-bar and mode-line highlight
        subroutine, clear any existing highlight, and revert the mouse
        pointer to its default shape.  (Bug#14558)

        * w32console.c (initialize_w32_display): Return the dimensions of
        the console window via 2 additional arguments, not via the current
        frame.  This avoids crashes due to overrunning the bounds of

        the change of the frame dimensions from the initial 10x10.

        * w32term.h (w32_initialize_display_info): Adjust prototype.

        * term.c (init_tty): Take dimensions of the frame from the values

        Mark EXTERNALLY_VISIBLE so they don't get optimized away by the
        compiler or linker.  Add extern decls to pacify gcc -Wall.

        Make it extern only if NS_IMPL_GNUSTEP is defined.

2013-06-03  Eli Zaretskii  <eliz@gnu.org>

        * w32.c (gettimeofday): Make the signature identical to prototype

        * xterm.h (GTK_PREREQ): New macro.
        All simple uses of GTK_MAJOR_VERSION and GTK_MINOR_VERSION changed

2013-05-07  Juri Linkov  <juri@jurta.org>

        * callint.c (Fcall_interactively): Set `visargs[i]' for code 'n'

        beginning of a display property or overlay for any "replacing"

        configure and build with -DUNEXELF_DEBUG without worrying about
        other modules that use DEBUG.
        (DEBUG_LOG) [UNEXELF_DEBUG]: New macro.  All debug code that prints
        possibly-wide integers now uses it instead of plain fprintf.
        (entry_address): New function, which avoids problems with 32-bit
        overflow on 64-bit hosts.

        (round_up): Don't assume the remainder fits in int.
        (find_section): Use bool for boolean.  Simplify debug code.
        (unexec): Don't assume file sizes fit in int or size_t.

        * regex.c: Fix problems when DEBUG is defined.
        (extract_number, extract_number_and_incr): Define regardless of
        whether DEBUG is defined; that's simpler and makes the code less
        likely to go stale in the normal case when DEBUG is not defined.
        Return int rather than taking an int * arg.  All callers changed.
        (DEBUG_PRINT1, DEBUG_PRINT2, DEBUG_PRINT3, DEBUG_PRINT4):
        Remove, replacing with ...
        (DEBUG_PRINT): New macro.  All callers changed.

        (print_fastmap, print_partial_compiled_pattern) [DEBUG]:
        (print_compiled_pattern, print_double_string) [DEBUG]:

        (print_partial_compiled_pattern, print_compiled_pattern) [DEBUG]:
        (ENSURE_FAIL_STACK, PUSH_FAILURE_REG) [DEBUG]:
        (POP_FAILURE_REG_OR_COUNT, PUSH_FAILURE_POINT) [DEBUG]:
        (POP_FAILURE_POINT, re_match_2_internal) [DEBUG]:
        Don't assume ptrdiff_t, size_t, and long are the same width as int.
        (POINTER_TO_OFFSET): Return ptrdiff_t, not regoff_t.
        This matters only when DEBUG is defined.

        * xdisp.c (set_iterator_to_next): Set the
        ignore_overlay_strings_at_pos_p flag only if we are _really_

        current.overlay_string_index member.  (Bug#14306)

2013-05-05  Jan Djärv  <jan.h.d@swipnet.se>

        * nsmenu.m (ns_update_menubar): Move initialization of submenuTitle
        to where it is used, to avoid autorelease issues (Bug#14050).

        * filelock.c (create_lock_file): If symbolic links don't work, so
        we use a regular file as a lock file, do not fsync the lock file;
        it's not needed.

2013-05-04  Stefan Monnier  <monnier@iro.umontreal.ca>

        * minibuf.c (Fread_minibuffer, Feval_minibuffer): Move to Elisp.

2013-04-27  Juri Linkov  <juri@jurta.org>

        * callint.c (Fcall_interactively): Call `Qread_number' for

        status to the safest one.

2013-04-22  Paul Eggert  <eggert@cs.ucla.edu>

        * Makefile.in (bootstrap-clean): Remove stamp-h1 too.
        Without this fix, "make distclean" leaves stamp-h1 behind.

2013-04-20  Erik Charlebois  <erikcharlebois@gmail.com>

        * w32fns.c (w32_fullscreen_rect): New function to compute the
        window rectangle for the given fullscreen mode.
        (w32_wnd_proc): When in a fullscreen mode, WM_WINDOWPOSCHANGING no
        longer tunes the window size.  This keeps the window's edges flush
        with the screen and allows the taskbar to hide itself in fullboth.

        * w32term.c (w32fullscreen_hook): 'fullboth' now shows without
        window decorations and uses the entire screen.

        * w32term.h  (w32_fullscreen_rect) Add prototype.
        (struct w32_output): Replace normal_width, normal_height,
        normal_top, and normal_left members with a single normal_placement
        struct.

        * buffer.c (syms_of_buffer) <left-margin-width, right-margin-width>:
        <left-fringe-width, right-fringe-width, fringes-outside-margins>:
        Mention in the doc string that setting these variables takes
        effect only after a call to set-window-buffer.  (Bug#14200)

2013-04-13  Eli Zaretskii  <eliz@gnu.org>

        * indent.c (Fvertical_motion): Don't consider display strings on
        overlay strings as display strings on the buffer position we
        started from.  This prevents vertical cursor motion from jumping
        more than one line when there's an overlay string with a display
        property at end of line.
        Reported by Karl Chen <Karl.Chen@quarl.org> in

        already selected (bug#14191).

2013-04-11  Eli Zaretskii  <eliz@gnu.org>

        * window.c (Fwindow_end): Test more flags, including the buffer's
        last_overlay_modified flag, to determine whether the window's
        display is really up-to-date.  Prevents the function from
        returning a stale value.  (Bug#14170)
        (Fwindow_line_height): Fix the test for up-to-date-ness of the
        current matrix.

2013-04-10  Eli Zaretskii  <eliz@gnu.org>

        * frame.c (do_switch_frame): Mark the TTY frame we switch to as
        garbaged only if it is not already the top frame on its TTY.
        This prevents flickering due to constant redrawing of TTY frames when
        there are GUI frames open in the same session.  (Bug#13864)

2013-04-10  Stefan Monnier  <monnier@iro.umontreal.ca>

        This bug was introduced by my 2013-02-25 change that simplified
        data_start configuration.  Without this change, on GNU/Linux
        an Emacs configured with --enable-profiling fails immediately
        due to a profiler signal.
        * Makefile.in: Compile with $(PROFILING_CFLAGS), but do not link
        with these flags.  On platforms where special flags are needed
        when linking temacs, the flags are now in LD_SWITCH_SYSTEM_TEMACS.
        (ALL_CFLAGS): Remove $(PROFILING_CFLAGS).
        (.c.o, .m.o): Compile with $(PROFILING_CFLAGS).

2013-04-07  Dmitry Antipov  <dmantipov@yandex.ru>

        Prefer < to > in range checks such as 0 <= i && i < N.
        This makes it easier to visualize quantities on a number line.
        This patch doesn't apply to all such range checks,
        only to the range checks affected by the 2013-03-24 change.

        * window.h (struct window): Replace hchild, vchild and buffer slots
        with a single slot 'contents'.  This is possible because each valid
        window may have either the child window (in vertical or horizontal
        combination) or buffer to display (for the leaf window).  Using that,
        a lot of operations to traverse and/or change window hierarchies may
        be simplified.  New member horizontal is used to distinguish between
        horizontal and vertical combinations of internal windows.

        Use contents slot, not buffer, where appropriate.
        * frame.c (set_menu_bar_lines_1): Use WINDOW_VERTICAL_COMBINATION_P
        and WINDOW_HORIZONTAL_COMBINATION_P.
        (make_frame_visible_1): Simplify the loop.
        Use contents slot, not buffer, where appropriate.
        * xdisp.c (hscroll_window_tree, mark_window_display_accurate)
        (redisplay_windows, redisplay_mode_lines, update_cursor_in_window_tree)
        (expose_window_tree): Likewise.
        Use contents slot, not buffer, where appropriate.
        * textprop.c (get_char_property_and_overlay): Add CHECK_LIVE_WINDOW
        to avoid deleted windows.  Use contents slot instead of buffer.

        automatically prepended.

        * w32term.c (w32_initialize): Silence compiler warning.

2013-03-23  Eli Zaretskii  <eliz@gnu.org>

        * w32term.c (w32fullscreen_hook): Use FRAME_NORMAL_WIDTH,
        FRAME_NORMAL_HEIGHT, and FRAME_PREV_FSMODE, instead of static
        variables, to save and restore frame dimensions.
        Use FRAME_NORMAL_LEFT and FRAME_NORMAL_TOP to restore frame position
        after returning from a 'fullscreen' configuration.
        use SendMessage instead of PostMessage to send the SC_RESTORE message,
        to avoid races between the main thread and the input thread.

        * w32term.h (struct w32_output): New members normal_width,
        normal_height, normal_top, normal_left, and prev_fsmode.
        (FRAME_NORMAL_WIDTH, FRAME_NORMAL_HEIGHT, FRAME_NORMAL_TOP)
        (FRAME_NORMAL_LEFT, FRAME_PREV_FSMODE): New macros to access these
        members of a frame.

        * w32term.c (w32fullscreen_hook): Record last value of the frame's
        'fullscreen' parameter.  Always record previous width and height
        of the frame, except when switching out of maximized modes, so
        that they could be restored correctly, instead of resetting to the
        default frame dimensions.  Send SC_RESTORE command to the frame,
        unless we are going to send SC_MAXIMIZE, to restore the frame
        resize hints in the mouse pointer shown by the window manager.
        (Bug#14032)

        * frame.c (get_frame_param): Now extern for WINDOWSNT as well.

        * dispnew.c (clear_current_matrices, clear_desired_matrices)

2013-03-21  Paul Eggert  <eggert@cs.ucla.edu>

        Use functions and constants to manipulate Lisp_Save_Value objects.
        This replaces code that used macros and strings and token-pasting.
        The change makes the C source a bit easier to follow,
        and shrinks the Emacs executable a bit.
        * alloc.c: Verify some properties of Lisp_Save_Value's representation.
        (make_save_value): Change 1st arg from string to enum.  All callers

        (SAVE_TYPE_PTR_PTR, SAVE_TYPE_PTR_PTR_OBJ, SAVE_TYPE_MEMORY):
        New constants.
        (struct Lisp_Save_Value): Replace members area, type0, type1, type2,
        type3 with a single member save_type.  All uses changed.

        Adjust users where appropriate.

2013-03-20  Dmitry Antipov  <dmantipov@yandex.ru>

        * frame.h (struct frame): Drop resx and resy because the same data is
        available from window system-specific output context.  Adjust users.
        (default_pixels_per_inch_x, default_pixels_per_inch_y):
        New functions to provide defaults when no window system available.
        (FRAME_RES_X, FRAME_RES_Y): New macros.
        (NUMVAL): Move from xdisp.c.
        * font.c (font_pixel_size, font_find_for_lface, font_open_for_lface)

2013-03-20  Kenichi Handa  <handa@gnu.org>

        * coding.c (syms_of_coding): Initialize disable_ascii_optimization
        to 1 (temporary workaround until a bug related to ASCII
        optimization is fixed).

2013-03-19  Dmitry Antipov  <dmantipov@yandex.ru>

        * window.c (Fwindow_combination_limit, Fset_window_combination_limit):
        Signal error if window is not internal.  Adjust docstring.

        * print.c (syms_of_print): Initialize debugging output not here...
        (init_print_once): ...but in a new function here.
        * lisp.h (init_print_once): Add prototype.
        * emacs.c (main): Add call to init_print_once.  Adjust comments.

2013-03-18  Dmitry Antipov  <dmantipov@yandex.ru>

2013-03-17  Ken Brown  <kbrown@cornell.edu>

        * dispextern.h (RGB_PIXEL_COLOR): Move here from image.c.  Use it
        as return type of image_background.  (Bug#13981)
        * image.c (RGB_PIXEL_COLOR): Move to dispextern.h.

2013-03-16  Jan Djärv  <jan.h.d@swipnet.se>

        * nsterm.m (updateFrameSize:): Change resize increments if needed.
        (ns_select): Don't return with result uninitialized.

        * nsterm.h (EmacsSavePanel, EmacsOpenPanel): Add getFilename
        and getDirectory.

        * nsfns.m (ns_filename_from_panel, ns_directory_from_panel):
        New functions.
        (Fns_read_file_name): ret is BOOL.  If ! dir_only_p, don't choose
        directories.  If filename is nil, get directory name (Bug#13932).
        Use getFilename and getDirectory.
        (getFilename, getDirectory): New methods for EmacsSavePanel and
        EmacsOpenPanel.
        (ok:): In EmacsOpenPanel, if we can't choose directories, just return.

        * insdel.c (insert_from_gap): New arg text_at_gap_tail.
        (adjust_after_replace): Make it back to static.  Delete the third

        * coding.c (detect_ascii): New function.
        (detect_coding): Set coding->head_ascii and coding->eol_seen only

        coding_category_utf_8_auto, call detect_ascii instead of scanning
        source bytes directly.
        (produce_chars): Call insert_from_gap with the new arg 0.
        (encode_coding): Likewise.
        (decode_coding_gap): Control ASCII optimization by the variable
        disable_ascii_optimization instead of #ifndef .. #endif.

        (syms_of_coding): Declare disable-ascii-optimization as a Lisp
        variable.

        (insert_cache_boundary, delete_cache_boundaries, set_cache_region):
        Simplify debugging check and convert to eassert.  Adjust comment.

        and WM_ACTIVATEAPP.
        (w32fullscreen_hook): If the frame is visible, reset
        f->want_fullscreen flag after changing the frame size.  If the

        (Bug#13953)

2013-03-13  Daniel Colascione  <dancol@dancol.org>

        * emacs.c (main): Call syms_of_cygw32 on CYGWIN non-NTGUI builds
        too so that these builds can use Cygwin's file conversion
        functions.  (We've been building and linking cygw32.o all along
        and just not using it.)

2013-03-13  Paul Eggert  <eggert@cs.ucla.edu>

        File synchronization fixes (Bug#13944).
        * Makefile.in (LIB_FDATASYNC): New macro.
        (LIBES): Use it.
        * conf_post.h (BSD_SYSTEM, BSD_SYSTEM_AHB): Remove; no longer needed.
        * fileio.c (Fwrite_region, write_region_inhibit_fsync):
        Don't worry about HAVE_FSYNC, since a substitute fsync is
        available if the system lacks one.
        (Fwrite_regin): Retry fsync if interrupted.

2013-03-13  Eli Zaretskii  <eliz@gnu.org>

        * w32term.c (w32_read_socket): If the Emacs frame is being
        activated, call w32fullscreen_hook, to make sure the new frame
        dimensions are in effect.  (Bug#13937)

2013-03-13  Dmitry Antipov  <dmantipov@yandex.ru>

        * xdisp.c (init_iterator): Simplify because both character and byte
        positions are either specified or -1.  Add eassert.  Adjust comment.
        * window.c (Fscroll_other_window): Use SET_PT_BOTH because both
        character and byte positions can be obtained from marker.

2013-03-13  Paul Eggert  <eggert@cs.ucla.edu>

        Static checking by Sun C 5.12.
        * alloc.c (buffer_memory_full) [REL_ALLOC]:
        * bytecode.c (exec_byte_code):
        * dispnew.c (init_display):
        * eval.c (error):
        * fileio.c (Fsubstitute_in_file_name):
        * keyboard.c (Fevent_convert_list):
        * keymap.c (Fsingle_key_description):
        * term.c (maybe_fatal, fatal):
        * xfns.c (Fx_display_backing_store, Fx_display_visual_class):
        * xsmfns.c (Fhandle_save_session):
        Omit unreachable code.
        * keymap.c (map_keymap_char_table_item): Cast void * to
        a function pointer type; the C Standard requires this.

        * sysdep.c: Remove a use of BSD_SYSTEM, which I'm trying to phase out.
        Include <sys/param.h> unconditionally, as that works elsewhere and
        is simpler here.  Include <sys/sysctl.h> if DARWIN_OS ||
        __FreeBSD__, not if BSD_SYSTEM, since it's needed only for Darwin
        and FreeBSD now.

See ChangeLog.12 for earlier changes.
