Make file descriptors close-on-exec when possible.

[emacs.git] / src / ChangeLog

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.

        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.

        * callproc.c (Fcall_process): Preserve openp errno around close.
        * lread.c (openp): Set errno when returning -1, as some callers

        by sendEvent (Bug#14578).
        (EmacsSavePanel, EmacsOpenPanel): Remove ok and cancel methods.

2013-07-06  Eli Zaretskii  <eliz@gnu.org>

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.

        (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.

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'.

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.

2013-06-29  Eli Zaretskii  <eliz@gnu.org>

        * xdisp.c (Fmove_point_visually): New function.

        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>

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.

        (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_XCAR, lisp_h_XCDR, lisp_h_XCONS, lisp_h_XHASH)
        (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)
        (MISCP, NILP, SET_SYMBOL_VAL, SYMBOL_CONSTANT_P, SYMBOL_VAL, SYMBOLP)
        (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)
        (make_number, XPNTR, XUNTAG, EQ, XCONS, XVECTOR, XSTRING, XSYMBOL)

        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.

        Tickle glib by waiting for Emacs itself, not for process 0 (Bug#14569).
        * process.c (init_process_emacs) [HAVE_GLIB && !WINDOWSNT]:

        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

        the buffer, to support window-specific overlays.  (Bug#14575)
        (compute_display_string_pos): When W is NULL, use the current
        buffer as the object to pass to get-char-property.
        (Fcurrent_bidi_paragraph_direction): Assign NULL to the window
        pointer member of the bidi iterator, since no window is pertinent

2013-06-08  Jan Djärv  <jan.h.d@swipnet.se>

        * xgselect.c: Remove unneeded include xterm.h.

        * process.c (wait_reading_process_output): Check for NS before GLIB.
        GLIB may be linked in due to rsvg, but ns_select must be called.

        * xgselect.c (xg_select): Remove call to window_system_available
        and g_main_context_pending at the top, so Gdk events (i.e. file
        notify) are processed when Emacs is started with -nw.

        See the thread containing
        <http://lists.gnu.org/archive/html/emacs-devel/2013-06/msg00109.html>.
        * gfilenotify.c (dir_monitor_callback, Fgfile_add_watch)
        (Fgfile_rm_watch): Don't assume EMACS_INT is the same width as a pointer.

2013-06-05  Eli Zaretskii  <eliz@gnu.org>

        * xdisp.c (handle_tool_bar_click): When mouse-highlight is off,
        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)

2013-06-05  Stefan Monnier  <monnier@iro.umontreal.ca>

        * lisp.mk (lisp): Add prog-mode.el.

        * syssignal.h (SA_SIGINFO): Default to 0.
        * xterm.c (x_term_init): Remove D-bus hack that I installed on May

        * 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
        frame's decode_mode_spec_buffer, which is not resized following
        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

        (backtrace_p, backtrace_top, backtrace_next):
        Mark EXTERNALLY_VISIBLE so they don't get optimized away by the
        compiler or linker.  Add extern decls to pacify gcc -Wall.

        * nsterm.m (ns_term_init):

        defined on all porting targets these days.
        * process.c, process.h (catch_child_signal):
        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

        (syms_of_xfns): DEFSYM them.

        beginning of a display property or overlay for any "replacing"

2013-05-06  Paul Eggert  <eggert@cs.ucla.edu>

        * unexelf.c: Fix some 32-bit integer problems, notably when debugging.

        configure and build with -DUNEXELF_DEBUG without worrying about
        other modules that use DEBUG.

        * regex.c: Fix problems when DEBUG is defined.
        (extract_number, extract_number_and_incr): Define regardless of

        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 ...

        we use a regular file as a lock file, do not fsync the lock file;
        it's not needed.

        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.

        * 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

        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>

        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).

        a lof of operations to traverse and/or change window hierarchies may

        MinGW64.
        Move inclusion of time.h before sys/time.h, so that MinGW64 could
        see its own definitions of 'struct timeval' and 'struct timezone'.

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

        (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

        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,

        resize hints in the mouse pointer shown by the window manager.

        New functions to provide defaults when no window system available.

        * 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.

        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.
