        * dispnew.c (redraw_frame): Remove useless #ifdef because
        FRAME_MSDOS_P is a compile-time zero everywhere except MS-DOS.
        Also, move TTY fflush to...
        * term.c (tty_update_end): ...this function.

2013-10-11  Eli Zaretskii  <eliz@gnu.org>

        * xdisp.c (display_tty_menu_item): Make sure we never write beyond
        the end of the frame's glyph matrix.  (Bug#15575)

        * term.c (tty_menu_display): Don't move cursor while overwriting
        frame's glyphs with menu items.  Limit the number of items
        displayed to what can be shown on the available screen lines,
        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):
        Use eassume, not eassert.
        * casetab.c (set_identity, shuffle):
        * composite.c (composition_gstring_put_cache):
        * dispnew.c (update_frame_1):
        * ftfont.c (ftfont_shape_by_flt):
        * image.c (gif_load):
        * intervals.c (offset_intervals):
        * macfont.m (macfont_shape):
        Remove calls to 'assume' that are no longer needed, because
        --enable-gcc-warnings no longer generates bogus warnings
        when these calls are removed.

2013-10-11  Dmitry Antipov  <dmantipov@yandex.ru>

        * xdisp.c (deep_copy_glyph_row): Remove unused locals.

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

        * fileio.c (Fsubstitute_in_file_name): Use substitute-env-in-file-name.
        (Qsubstitute_env_in_file_name): New var.
        (syms_of_fileio): Define it.

2013-10-10  Eli Zaretskii  <eliz@gnu.org>

        * xdisp.c (deep_copy_glyph_row): Assert that the 'used' counts of
        FROM and TO are identical.  Copy only the glyphs of TEXT_AREA.
        (Bug#15575)

        * term.c (save_and_enable_current_matrix): Don't allocate and
        don't save margin areas.
        (restore_desired_matrix): Don't restore margin areas.
        (free_saved_screen): Don't free margin areas.

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

        * image.c: Pacify --enable-gcc-warnings.
        (GIFLIB_MAJOR, GIFLIB_MINOR, GIFLIB_RELEASE, fn_GifErrorString):
        #define only if used.

2013-10-10  Eli Zaretskii  <eliz@gnu.org>

        * image.c (GIFLIB_MAJOR): Define to 4 if undefined.
        (GIFLIB_MINOR, GIFLIB_RELEASE): Define to zero if undefined.
        (GifErrorString) [GIFLIB_MAJOR >= 5]: Define a function pointer.
        (gif_load): For giflib v5.x and later, display the error message
        produced by giflib when its functions fail.
        (syms_of_image) <Qlibgif_version> [HAVE_NTGUI]: New DEFSYM.
        (Bug#15531)

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

        * keyboard.c (last_event_timestamp): Remove.  For X selection and
        GTK popup menus, it may be obtained from per-frame X display info.
        (kbd_buffer_store_event_hold, kbd_buffer_get_event)
        (process_special_events): Adjust users.
        * keyboard.h (last_event_timestamp): Remove declaration.
        * xmenu.c (xmenu_show, create_and_show_popup_menu): Lost last arg.
        Use FRAME_DISPLAY_INFO (f)->last_user_time for gtk_menu_popup.
        * menu.h (xmenu_show): Adjust prototype.
        * menu.c (Fx_popup_menu): Adjust user.
        * xselect.c (x_own_selection, x_get_foreign_selection)
        (Fx_disown_selection_internal): Use dpyinfo->last_user_time.

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

        * keyboard.c (init_kboard): Now static.  Add arg
        to denote window system.  Adjust comment.
        (init_keyboard): Adjust user.
        (allocate_kboard): New function.
        (syms_of_keyboard):
        * nsterm.m (ns_term_init):
        * term.c (init_tty):
        * w32term.c (w32_create_terminal):
        * xterm.c (x_term_init): Use it.
        * keyboard.h (init_kboard): Remove prototype.
        (allocate_kboard): Add prototype.

2013-10-10  Barry Fishman  <barry_fishman@acm.org>  (tiny change)

        * image.c (GIFLIB_MAJOR): Ensure it's defined.
        (DGifOpen, DGifOpenFileName): Handle giflib 5 syntax.  (Bug#15531)

2013-10-09  Paul Eggert  <eggert@cs.ucla.edu>

        * fns.c (sxhash_bool_vector): Fix buffer read overrun.

2013-10-09  Eli Zaretskii  <eliz@gnu.org>

        * term.c (tty_menu_activate): Flush the output stream after
        showing the cursor, and don't mark the frame garbaged at exit from
        the function.  Fixes redisplay glitches when moving from one menu
        to another.

2013-10-09  Jan Djärv  <jan.h.d@swipnet.se>

        * nsfns.m (Fns_convert_utf8_nfd_to_nfc): Check input for valid UTF-8
        or throw error (Bug#15570).

2013-10-09  Paul Eggert  <eggert@cs.ucla.edu>

        * 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.

2013-10-09  Glenn Morris  <rgm@gnu.org>

        * eval.c (Fcond): Doc tweak.

2013-10-09  Eli Zaretskii  <eliz@gnu.org>

        * xfaces.c (x_free_gc) [HAVE_X_WINDOWS, HAVE_NTGUI]: Don't pass
        expressions with side effects to eassert.  (Bug#15565)

2013-10-09  Stefan Monnier  <monnier@iro.umontreal.ca>

        * fns.c (hashfn_user_defined): Allow hash functions to return any
        Lisp_Object.

2013-10-08  Paul Eggert  <eggert@cs.ucla.edu>

        Fix minor problems found by static checking.

        benefit of STRING_CHAR_AND_LENGTH.  All uses changed.
        Return ptrdiff_t, not int.
        * term.c (tty_menu_struct): 'allocated' member is now ptrdiff_t,
        not int, for benefit of xpalloc.
        (tty_menu_create, tty_menu_make_room): Simplify by using xzalloc
        and xpalloc.
        (have_menus_p): Remove; unused.
        (tty_menu_add_pane, tty_menu_add_selection): Change signedness of
        local char * pointer to pacify STRING_CHAR_AND_LENGTH.

        Now static.
        (save_and_enable_current_matrix): Omit unnecessary casts.
        (read_menu_input): Omit local extern decl (now in lisp.h).
        Don't access uninitialized storage if mouse_get_xy fails.
        (tty_menu_activate): Mark local as initialized, for lint.
        (tty_menu_activate, tty_meny_show): Remove unused locals.

        (cursorY): New functions.

        * termhooks.h (cursorX, cursorY): Prototypes of functions on

        of in x-popup-menu.
        (ns_popup_dialog): Adapt order of arguments to the other
        *_menu_show implementations.
        (Fx_popup_dialog): Function deleted.

        * msdos.c (x_set_menu_bar_lines): Delete unused function.

        * menu.h (tty_menu_show, menu_item_width): provide prototypes.

        * menu.c (have_boxes): New function.
        (single_keymap_panes): Use it instead of a compile-time
        conditional.
        (single_menu_item): Use run-time tests of the frame type instead
        of compile-time conditionals.
        (encode_menu_string): New function.
        (list_of_items, list_of_panes): Use it instead of ENCODE_STRING

        (Fx_popup_menu): Detect when the function is called from keyboard
        on a TTY.  Don't barf when invoked on a text-mode frame.
        Check frame type at run time, instead of compile-time conditionals for
        invoking terminal-specific menu-show functions.
        Call tty_menu_show on text-mode frames.
        (Fx_popup_dialog): Move here from xmenu.c.  Test frame types at
        run time to determine which alternative to invoke; support dialogs
        on TTYs.

        * keyboard.c <Qmouse_movement>: Now extern.
        <Qecho_keystrokes>: New static variable.

        * dispextern.h (set_window_update_flags): Adjust prototype.
        * xdisp.c (redisplay_internal): When updating all frames with zero
        windows_or_buffers_changed, assume that only the windows that shows
        current buffer should be really updated.

2013-10-08  Dmitry Antipov  <dmantipov@yandex.ru>

        Do not allocate huge temporary memory areas and objects while encoding
        for file I/O, thus reducing an enormous memory usage for large buffers.
        See http://lists.gnu.org/archive/html/emacs-devel/2013-10/msg00180.html.
        * coding.h (struct coding_system): New member raw_destination.

        Fix race where emacs aborts when sent SIGTERM (Bug#15534).
        * keyboard.c (unblock_input_to): Don't process pending signals
        if a fatal error is in progress.

        * lisp.h (bits_word, BITS_WORD_MAX): New type and macro.
        All uses of 'size_t' and 'SIZE_MAX' changed to use them, when
        they're talking about words in Lisp bool vectors.
        (BITS_PER_BITS_WORD): Rename from BITS_PER_SIZE_T.  All uses changed.
        * data.c (popcount_bits_word): Rename from popcount_size_t.

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):

        (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,

        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>

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.

        * data.c (POPCOUNT_STATIC_INLINE): New macro, as a hack for popcount.
        This is ugly, but it should fix the performance problem for older

        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

        * frame.h (struct frame): Remove force_flush_display_p.
        * dispnew.c (update_frame): Adjust user and don't call
        flush_frame here.  The comment has said that there was an issues

        Drop flush_display_optional because flush_display is enough

        * dispnew.c (update_frame):

        Adjust to use per-frame bitfield.
        (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
        selected frame only, do not use fast update.

        (_sys_wait_accept): Wait for accept event in a loop with a finite

        (SET_RANGE_TABLE_WORK_AREA_BIT, SET_RANGE_TABLE_WORK_AREA):
        Only define if emacs.

        Fix comment.
        (window_box, window_box_width, window_box_left, window_box_left_offset)
        (window_box_right, window_box_right_offset): Adjust prototypes.
        * xdisp.c (window_box, window_box_width, window_box_left)
        (window_box_left_offset, window_box_right, window_box_right_offset):
        Use enum glyph_row_area.  Adjust users and tweak comment where needed.
        (window_box_edges): Likewise.  Lost 2nd arg since it is always ANY_AREA.
        * nsterm.m (ns_clip_to_row):
        * w32term.c (w32_clip_to_row):
        * xterm.c (x_clip_to_row): Likewise.

        (Fprevious_overlay_change): Fast path for buffer with no overlays.

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.

        * xterm.c (x_update_window_begin, x_update_window_end):
        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.
        (EMACS_TIME_RESOLUTION): Remove.  All uses changed to
        TIMESPEC_RESOLUTION.

        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...

        * termchar.h (toplevel):
        * xterm.h (toplevel): Include dispextern.h.

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

        Fix minor problems found by static checking.
        * image.c (XGetPixel, XPutPixel) [HAVE_NS]: Now static.
        (expect): Avoid nested-if warning.
        (x_build_heuristic_mask) [HAVE_NS]: Avoid unused-var warning.
        * nsmenu.m (fillWithWidgetValue:): Avoid type warning.
        * 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>

        * lread.c (substitute_object_recurse): Handle hash-tables as well
        (bug#15190).

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
        of VoidSymbol (Bug#15154).

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

        * lisp.h (Mouse_HLInfo): Drop set-but-unused members

        (mouse_face_from_string_pos, note_mode_line_or_margin_highlight):
        Adjust users and update comment where appropriate.

2013-08-26  Martin Rudalics  <rudalics@gmx.at>

        * frame.c (check_minibuf_window): New function.
        (delete_frame, Fmake_frame_invisible, Ficonify_frame):
        Call check_minibuf_window (Bug#15183).

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
        initialization of Qchar_table_extra_slots just once...
        * 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).

2013-08-24  Paul Eggert  <eggert@cs.ucla.edu>

        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.
        * callproc.c (encode_current_directory): New function.
        (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.
        * frame.h (enum text_cursor_kinds): Move from here...
        * dispextern.h (enum text_cursor_kinds): ...to here.
        (toplevel): Drop unnecessary declarations.
        (struct redisplay_interface): Use bool and enum text_cursor_kinds
        in update_window_end_hook and draw_window_cursor functions.
        (display_and_set_cursor, x_update_cursor): Adjust prototypes.
        * nsterm.m (ns_update_window_end, ns_draw_window_cursor):
        * w32term.c (x_update_window_end, w32_draw_window_cursor):
        * xterm.c (x_update_window_end, x_draw_window_cursor):
        * xdisp.c (display_and_set_cursor, update_window_cursor)
        (update_cursor_in_window_tree, x_update_cursor): Use bool and
        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.
        * dispnew.c (updated_row, updated_area): Remove.
        (redraw_overlapped_rows, update_window_line): Adjust user.
        (update_marginal_area, update_text_area): Likewise.  Pass updated row
        as a parameter.  Prefer enum glyph_row_area to int where appropriate.
        * xdisp.c (x_write_glyphs, x_insert_glyphs, x_clear_end_of_line):
        Adjust users.

2013-08-22  Paul Eggert  <eggert@cs.ucla.edu>

        * process.c (flush_pending_output): Remove stub.
        All uses removed.

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

        * callproc.c: Fix race that killed background processes (Bug#15144).
        (call_process): New arg TEMPFILE_INDEX.  Callers changed.
        Record deleted process-id in critical section, not afterwards.
        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)

        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

        * 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).

        There's still some problems with background color settings, though
        (bug#14700).

        * decompress.c (unwind_decompress): Always restore point.

2013-08-14  Xue Fuqiao  <xfq.free@gmail.com>

        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.

        (Fzlib_decompress_region): Don't bother verifying
        that avail_out <= UINT_MAX, as that was confusing.
        Mention the restriction in a comment instead.
        Prefer 'int' to 'ptrdiff_t' when 'int' is wide enough.

        * w32term.c (x_scroll_bar_create): Use ALLOCATE_PSEUDOVECTOR, not
        Fmake_vector, as scroll bar's struct members are not all Lisp
        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>

        All Obj-C code uses BOOL, except for interfaces callable from C.

        * nsterm.h: Fix CGFloat for OSX 10.4 (Bug#15086).

2013-08-13  Dmitry Antipov  <dmantipov@yandex.ru>

        * window.h (WINDOW_FRINGE_EXTENDED_P): New macro.

        from Lisp_Object to bitfield.  Adjust comment.
        * w32term.c (x_scroll_bar_create): Adjust user.

        Use bool for boolean.
        * xterm.h (struct scroll_bar): Prefer commonly used `unsigned'

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)

        * 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.

        Be more careful if selected window shows the buffer other than current,

2013-08-02  Jan Djärv  <jan.h.d@swipnet.se>

        * nsterm.m (windowWillResize:toSize:): Only change title if
        ! maximizing_resize && FULLSCREEN_NONE (Bug#15005).  strdup title before
        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.

2013-08-01  Paul Eggert  <eggert@cs.ucla.edu>

        * fileio.c, fns.c (merge): Move extern decl from here ...
        * lisp.h (merge): ... to here.

2013-08-01  Dmitry Antipov  <dmantipov@yandex.ru>

        Fix last font-related change.
        * w32font.h (w32font_list_internal, w32font_match_internal):
        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.

2013-07-31  Dmitry Antipov  <dmantipov@yandex.ru>

        Drop unnecessary functions that deals with frame pixel size.
        * 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.
        * eval.c (get_backtrace_frame, backtrace_eval_unrewind): Now static.
        (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.
        * alloca.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]:

        * xdisp.h (pop_message_unwind):
        * xselect.c (queue_selection_requests_unwind):
        Remove no-longer-needed wrapper.  All uses replaced by the wrappee.
        * alloca.c (record_xmalloc):
        Prefer record_unwind_protect_ptr to record_unwind_protect with
        make_save_pointer.
        * alloca.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]:

        (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)

        * 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.

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.

        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):

        * 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)

        (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.

        (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_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:
        * emacs.c:
        * callproc.c [WINDOWSNT]: Include sys/socket.h.

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.

        * nsterm.h (NSSavePanel): Update comment.

        * 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>

        * xdisp.c (default_line_pixel_height): New function.
        (pos_visible_p, move_it_vertically_backward, try_scrolling)
        (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.
        * src/systdio.h: New file.
        * src/buffer.c (mmap_init):
        * cygw32.c (chdir_to_default_directory):

        * w32term.c (w32_initialize) [CYGWIN]:
        * xfaces.c (Fx_load_color_file):
        Use emacs_open instead of plain open, and emacs_fopen instead of
        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.
        * callproc.c (default_output_mode): New constant.
        (Fcall_process): Use it to call emacs_open instead of plain creat.
        * dispnew.c (Fopen_termscript): Fix minor race in opening termscript.
        * sysdep.c (emacs_open): Add commentary and don't call file name "path".

        Remove duplicate #include directives.
        * alloc.c [GC_MARK_STACK == GC_USE_GCPROS_CHECK_ZOMBIES]:

        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>

        * 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.
        (inotifyevent_to_event): Exchange order of cookie and file name.
        (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)

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)
        (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
        to this function.

2013-06-08  Eli Zaretskii  <eliz@gnu.org>

        * bidi.c (bidi_fetch_char): Accept additional argument, the window
        being displayed, and pass it to compute_display_string_pos.
        (bidi_level_of_next_char, bidi_resolve_explicit_1)
        (bidi_paragraph_init): All callers changed.

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.

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

        * Makefile.in (ctagsfiles1, ctagsfiles2): Don't include *.m files.
        (ctagsfiles3): New variable, includes only *.m files.
        (TAGS): Use an explicit language name in the regular expressions,
        to avoid transformation of '/SOMETHING' by MSYS to
        'c:\MSYS\SOMETHING'.

2013-06-07  Richard Copley  <rcopley@gmail.com>  (tiny change)

        (Bug#14558)

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

        A few porting etc. fixes for the new file monitor code.
        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.
        (dir_monitor_callback, Fgfile_rm_watch):
        Use assq_no_quit instead of Fassoc, for speed.
        (dir_monitor_callback, Fgfile_rm_watch):
        eassert that the monitor is a fixnum.
        (dir_monitor_callback): No need for CDR_SAFE.
        Simplify building of lisp with alternative tails.
        (Fgfile_add_watch, Fgfile_rm_watch):
        Do not assume glib functions set errno reliably on failure.
        (Fgfile_add_watch): Check that the monitor survives the XIL trick,
        and signal an error otherwise.
        (Fgfile_rm_watch): Prefer CONSP to !NILP.
        Use Fdelq instead of Fdelete, for speed.

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.

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

        (handle_child_signal): Invoke it.
        (catch_child_signal): If a library has set up a signal handler,
        save it into lib_child_handler.
        (init_process_emacs): If using glib and not on Windows, tickle glib's
        child-handling code so that it initializes its private SIGCHLD handler.

        some window, increment windows_or_buffers_changed, so that
        *Messages* display in that window is updated.  (Bug#14408)

        * w32.c: Include epaths.h.
        (init_environment): Use cmdproxy.exe without leading directories.

        expectations.

        * unexw32.c (open_output_file): Delete the existing emacs.exe
        before creating it, to break the hard link to the versioned
        executable.

        * Makefile.in (EMACS_MANIFEST, CM_OBJ, TEMACS_POST_LINK)

2013-05-08  Paul Eggert  <eggert@cs.ucla.edu>

        * xterm.h (GTK_PREREQ): New macro.
        All simple uses of GTK_MAJOR_VERSION and GTK_MINOR_VERSION changed
        to use this macro instead, for consistency and clarity.

2013-05-08  Eli Zaretskii  <eliz@gnu.org>

        * xdisp.c (row_for_charpos_p): New function, with code of
        cursor_row_p, but accepts an additional argument CHARPOS instead
        of using a hardcoded PT.
        (cursor_row_p): Call row_for_charpos_p with 2nd argument PT.
        (row_containing_pos): Call row_for_charpos_p instead of partially
        doing the same.  Fixes cursor positioning under longlines-mode
        when longlines-show-effect includes more than one newline, when
        moving the cursor vertically up.

2013-05-08  Juanma Barranquero  <lekktu@gmail.com>

        * makefile.w32-in (ACL_H): New macro.

        !acl_errno_valid.
        (Fcopy_file) [!WINDOWSNT]: Use qcopy_acl instead of rolling
        it ourselves.

        * unexelf.c: Don't assume ElfW (Half) fits in int.
        (entry_address, find_section, unexec): Use ptrdiff_t, not int,
        when dealing with ElfW (Half) values, since they can exceed 2**31
        on 64-bit OpenBSD hosts.  Problem reported privately by Han Boetes.
        (entry_address): Omit unused NUM arg.  All uses changed.

2013-05-07  Juri Linkov  <juri@jurta.org>

        * callint.c (Fcall_interactively): Set `visargs[i]' for code 'n'
        to the string converted from number with `Fnumber_to_string'.

2013-05-07  Jan Djärv  <jan.h.d@swipnet.se>

        * xfns.c: Move misplaced ifndef USE_GTK from previous checkin.

2013-05-07  Paul Eggert  <eggert@cs.ucla.edu>

        Static checking by GCC 4.8.0.
        * xfns.c (x_get_net_workarea, struct MonitorInfo, free_monitors)
        (x_get_monitor_for_frame, x_make_monitor_attribute_list)
        (x_get_monitor_attributes_fallback)

        (x_get_monitor_attributes_xinerama, Fx_display_monitor_attributes_list):
        Use double, not float, to avoid mixed-mode floating point arithmetic.

2013-05-07  YAMAMOTO Mitsuharu  <mituharu@math.s.chiba-u.ac.jp>
            Jan Djärv  <jan.h.d@swipnet.se>

        * Makefile.in (XRANDR_LIBS, XRANDR_CFLAGS, XINERAMA_LIBS)
        (XINERAMA_CFLAGS): New macros.
        (ALL_CFLAGS, LIBES): Use them.

        * xfns.c: Include <X11/extensions/Xrandr.h> if HAVE_XRANDR, and
        include <X11/extensions/Xinerama.h> if HAVE_XINERAMA.
        (Qgeometry, Qworkarea, Qmm_size, Qframes, Qsource): New variables.
        (syms_of_xfns): DEFSYM them.
        (struct MonitorInfo): New struct.
        (x_get_net_workarea, free_monitors, x_get_monitor_for_frame)
        (x_make_monitor_attribute_list, x_get_monitor_attributes_fallback)

        and dpyinfo->Xatom_net_current_desktop.

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

        * xdisp.c (pos_visible_p): Use the special code for finding the
        beginning of a display property or overlay for any "replacing"
        display property, not just for display strings.  This solves
        incorrect reporting of position by posn-at-point.  (Bug#14241)

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

        * unexelf.c: Fix some 32-bit integer problems, notably when debugging.
        Include <limits.h>, <stdbool.h>, <intprops.h>, <verify.h>.
        Verify that ElfW (Half) fits in int.
        (fatal): Use same signature as lisp.h.
        (UNEXELF_DEBUG): New macro, replacing DEBUG, so that people can
        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.
        (OLD_SECTION_H, NEW_SECTION_H, NEW_PROGRAM_H): Use it.
        (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.
        Omit unnecessary trailing newline in 'fatal' format.
        Use strerror rather than outputting decimal error number.
        Remove unused code when emacs is not defined;
        this file relies on Emacs now.
        Don't assume e_phnum and e_shnum are positive.

        * 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.
        (DEBUG_COMPILES_ARGUMENTS): New macro.
        (print_fastmap, print_partial_compiled_pattern) [DEBUG]:
        (print_compiled_pattern, print_double_string) [DEBUG]:
        Use prototype rather than old-style definition.
        (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.

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

        * xdisp.c (set_iterator_to_next): Set the
        ignore_overlay_strings_at_pos_p flag only if we are _really_
        iterating over an overlay string, as indicated by the
        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).

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

        `write-region-inhibit-fsync' defaults to noninteractive (Bug#14273).
        * fileio.c (syms_of_fileio): Implement this.
        * 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.
        (syms_of_minibuf): Adjust accodingly.
        * lread.c (Fread):
        * callint.c (Fcall_interactively): Adjust calls accordingly.

2013-05-04  Eli Zaretskii  <eliz@gnu.org>

        * dispextern.h (WINDOW_WANTS_HEADER_LINE_P): Verify that
        w->contents is a buffer before computing everything else.
        Use parentheses to disambiguate last part of the condition.

        * w32fns.c (w32_wnd_proc): Remove temporary code used to trap
        assertion violations.  (Bug#14062)

2013-05-01  David Reitter  <david.reitter@gmail.com>

2013-04-28  Dan Nicolaescu  <dann@gnu.org>

        * dispextern.h (struct face): Move enum face_underline_type
        earlier so that bitfields can be in the same word.

2013-04-28  Jan Djärv  <jan.h.d@swipnet.se>

        * nsfns.m (handlePanelKeys): New function.
        (EmacsOpenPanel:performKeyEquivalent:)
        (EmacsSavePanel:performKeyEquivalent:): Call handlePanelKeys to handle
        arrows/function/control and copy/paste keys (Bug#14296).

2013-04-27  Juri Linkov  <juri@jurta.org>

        * callint.c (Fcall_interactively): Call `Qread_number' for
        interactive code letter `n' instead of using duplicate code.
        (Bug#14254)

2013-04-27  Paul Eggert  <eggert@cs.ucla.edu>

        * systime.h (make_timeval): Declare as 'const'.

        * font.c (font_open_entity): Always open a font of manageable
        size.

2013-04-26  Paul Eggert  <eggert@cs.ucla.edu>

        Port better to AIX (Bug#14258).
        * lisp.h (ENUM_BF) [__IBMC__]: Make it 'unsigned int' here, too,
        to pacify AIX xlc.

2013-04-24  Kenichi Handa  <handa@gnu.org>

        * coding.c (decode_coding_iso_2022): When an invalid escape
        sequence is encountered, reset the invocation and designation
        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.

        Remove macros.
        (FRAME_NORMAL_PLACEMENT): New macro.

        * w32fns.c (w32_wnd_proc): Add more assertions to investigate
        bug#14062.

        * frame.h (WINDOW_FRAME): Protect macro and its argument with
        parentheses.

        * dispextern.h (CURRENT_MODE_LINE_HEIGHT)
        (CURRENT_HEADER_LINE_HEIGHT, WINDOW_WANTS_MODELINE_P)
        (WINDOW_WANTS_HEADER_LINE_P): Protect macro arguments with

2013-04-14  Eli Zaretskii  <eliz@gnu.org>

        * 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
        http://lists.gnu.org/archive/html/emacs-devel/2013-04/msg00362.html.

2013-04-12  Stefan Monnier  <monnier@iro.umontreal.ca>

        * window.c (select_window): `record_buffer' even if window is
        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>

        * keyboard.c (timer_start_idle): Call internal-timer-start-idle instead

        temporarily broken (bug#14161).

        * fns.c (Fdelq): Don't assume !NILP => CONSP.

        * fileio.c (ACL_NOT_WELL_SUPPORTED): Define macro for WINDOWSNT.

2013-04-07  Romain Francoise  <romain@orebokech.com>

        Ignore additional platform-specific ACL errors (Bug#13702).
        * fileio.c (ACL_NOT_WELL_SUPPORTED): New macro copied from gnulib.

        Fix --enable-profiling bug introduced by 2013-02-25 change (Bug#13783).
        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).

        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.

        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.

        (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

        * w32fns.c (emacs_abort) [CYGWIN]: Define `_open' as a macro to
        fix compilation on 64-bit Cygwin, where underscores are not
        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.

        * lisp.h (get_frame_param): Adjust conditions for prototype
        declaration.

2013-03-22  Ken Brown  <kbrown@cornell.edu>

        (report_sheap_usage): Declare.
        (read_exe_header): Add magic numbers for x86_64.
        (fixup_executable): Fix printf format specifier for unsigned long
        argument.

2013-03-22  Dmitry Antipov  <dmantipov@yandex.ru>

        * frame.h (struct frame): Put menu_bar_window under #ifdef
        because this member is not needed when X toolkit is in use.
        (fset_menu_bar_window):
        * dispnew.c (clear_current_matrices, clear_desired_matrices)
        (free_glyphs, update_frame):
        * xdisp.c (expose_frame): Likewise.
        (display_menu_bar): Likewise.  Remove redundant eassert.
        * window.h (WINDOW_MENU_BAR_P): Always define to 0 if X
        toolkit is in use.

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
        changed.
        (INTX): Remove.

        * lisp.h (SAVE_VALUEP, XSAVE_VALUE, XSAVE_POINTER, XSAVE_INTEGER)
        (XSAVE_OBJECT): Now functions, not macros.
        (STRING_BYTES_BOUND): Now just a macro, not a constant too;
        the constant was never used.
        (SAVE_SLOT_BITS, SAVE_VALUE_SLOTS, SAVE_TYPE_BITS, SAVE_TYPE_INT_INT)
        (SAVE_TYPE_INT_INT_INT, SAVE_TYPE_OBJ_OBJ, SAVE_TYPE_OBJ_OBJ_OBJ)
        (SAVE_TYPE_OBJ_OBJ_OBJ_OBJ, SAVE_TYPE_PTR_INT, SAVE_TYPE_PTR_OBJ)
        (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.
        (save_type, set_save_pointer, set_save_integer): New functions.
        * print.c (PRINTX): Remove.

        * alloc.c: Remove redundant static declarations.

        Remove.
        (WINDOW_TOTAL_COLS, WINDOW_TOTAL_LINES, WINDOW_LEFT_EDGE_COL)
        (WINDOW_TOP_EDGE_LINE): Drop Lisp_Object to integer conversion.
        * dispnew.c, frame.c, w32fns.c, window.c, xdisp.c, xfns.c:
        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)
        (Ffont_face_attributes, Fopen_font):
        * image.c (gs_load):
        * w32font.c (fill_in_logfont):
        * xdisp.c (calc_pixel_width_or_height):
        * xfaces.c (Fx_family_fonts, set_lface_from_font): Use them.
        * xsettings.c (apply_xft_settings): Drop frame loop and adjust comment.

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.
        (delete_all_child_windows): Use combination_limit to save the buffer.
        (Fset_window_configuration): Adjust accordingly.
        * 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>

        * window.c (window_resize_check, window_resize_apply)
        (window_from_coordinates, recombine_windows, set_window_buffer)
        (make_parent_window, Fwindow_resize_apply, resize_frame_windows)
        (Fsplit_window_internal, Fdelete_window_internal)
        (freeze_window_starts): Use bool for booleans.
        * window.h (window_frame_coordinates, resize_frame_windows)
        (freeze_window_starts, set_window_buffer): Adjust prototypes.

2013-03-17  Stefan Monnier  <monnier@iro.umontreal.ca>

        * dispnew.c (bitch_at_user): Use `user-error'.

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.

2013-03-15  Paul Eggert  <eggert@cs.ucla.edu>

        * coding.c (decode_coding_gap): Fix typo caught by static checking.

2013-03-15  Kenichi Handa  <handa@gnu.org>

        * insdel.c (insert_from_gap): New arg text_at_gap_tail.
        (adjust_after_replace): Make it back to static.  Delete the third
        arg text_at_gap_tail.  Cancel the code for handling it.

        * coding.h (struct coding_system): New member eol_seen.

        * coding.c (detect_ascii): New function.
        (detect_coding): Set coding->head_ascii and coding->eol_seen only
        when the source bytes are actually scanned.  On detecting for
        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.
        Deccode EOL format according to coding->eol_seen.
        (syms_of_coding): Declare disable-ascii-optimization as a Lisp
        variable.

        * lisp.h (adjust_after_replace): Cancel externing it.
        (insert_from_gap): Adjust prototype.

        FULLSCREEN_MAXIMIZED.  (Bug#13935)

2013-03-15  Dmitry Antipov  <dmantipov@yandex.ru>

        * region-cache.c (find_cache_boundary, move_cache_gap)
        (insert_cache_boundary, delete_cache_boundaries, set_cache_region):
        Simplify debugging check and convert to eassert.  Adjust comment.
        (pp_cache): Put under ENABLE_CHECKING.

2013-03-14  Eli Zaretskii  <eliz@gnu.org>

        * w32term.c (w32_read_socket) <WM_WINDOWPOSCHANGED>: Remove old
        and incorrect code.  Treat WM_WINDOWPOSCHANGED like WM_ACTIVATE
        and WM_ACTIVATEAPP.
        (w32fullscreen_hook): If the frame is visible, reset
        f->want_fullscreen flag after changing the frame size.  If the
        frame is not visible, set f->want_fullscreen to FULLSCREEN_WAIT.
        (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.
