FILE's lock is now always .#FILE and may be a regular file.

[bpt/emacs.git] / src / ChangeLog

2013-03-05  Paul Eggert  <eggert@cs.ucla.edu>

        FILE's lock is now always .#FILE and may be a regular file (Bug#13807).
        * filelock.c: Include <c-ctype.h>.
        (MAX_LFINFO): New top-level constant.
        (lock_info_type): Remove members pid, boot_time.  Add members at,
        dot, colon.  Change user member to be the entire buffer, not a
        pointer.  This allows us to handle the case where a foreign
        pid or boot time exceeds the local range.  All uses changed.
        (LINKS_MIGHT_NOT_WORK): New constant.
        (FREE_LOCK_INFO): Remove, as the pieces no longer need freeing.
        (defined_WINDOWSNT): Remove.
        (MAKE_LOCK_NAME, file_in_lock_file_name):
        Always use .#FILE (not .#-FILE) for the file lock,
        even if it is a regular file.
        (rename_lock_file): New function.
        (create_lock_file): Use it.
        (create_lock_file, read_lock_data):
        Prefer a symbolic link for the lock file, falling back on a
        regular file if symlinks don't work.  Do not try to create
        symlinks on MS-Windows, due to security hassles.  Stick with
        POSIXish functions (open, read, write, close, fchmod, readlink, symlink,
        link, rename, unlink, mkstemp) when creating locks, as a GNUish
        host may be using a Windowsish file system, and cannot use
        MS-Windows-only system calls.  Fall back on mktemp if mkstemp
        doesn't work.  Don't fail merely because of a symlink-contents
        length limit in the current file system; fall back on regular
        files.  Increase the symlink contents length limit to 8 KiB, this
        should be big enough for any real use and doesn't crunch the
        stack.
        (create_lock_file, lock_file_1, read_lock_data):
        Simplify allocation of lock file buffers now that they fit in 8 KiB.
        (lock_file_1): Return error number, not bool.  All callers changed.
        (ELOOP): New macro, if not already defined.
        (read_lock_data): Return size of lock file contents, not Lisp object.
        All callers changed.  Handle a race condition if some other process
        replaces a regular-file lock with a symlink lock or vice versa,
        while we're trying to read the lock.
        (current_lock_owner): Parse contents more carefully, to help avoid
        confusing a regular-file lock with some other application's use
        of the file.  Check for lock file contents being too long, or
        not parsing correctly.
        (current_lock_owner, lock_file):
        Allow foreign pid and boot times that exceed the local range.
        (current_lock_owner, lock_if_free, lock_file):
        Simplify allocation of lock file contents.
        * w32.c (sys_rename_replace): New function, containing most of
        the contents of the old sys_rename.
        (sys_rename): Use it.
        (fchmod): New dummy function.
        * w32.h (sys_rename_replace, fchmod): New decls.

2013-03-05  Eli Zaretskii  <eliz@gnu.org>

        * bidi.c (bidi_resolve_explicit_1): Don't call CHAR_TO_BYTE or
        bidi_count_bytes, as the callers now arrange for bidi_it->charpos
        to be in sync with bidi_it->bytepos.  Suggested by Dmitry Antipov
        <dmantipov@yandex.ru>.

2013-03-05  Paul Eggert  <eggert@cs.ucla.edu>

        Fix a build failure on OpenBSD 4.x and MirBSD.
        * sysdep.c (KERN_PROC, kinfo_proc)
        [BSD_SYSTEM && (!KERN_PROC || __MirBSD__)]:
        Define to KERN_PROC2 and kinfo_proc2, for OpenBSD 4.9 and MirBSD.
        list-system-processes still returns nil, but at least it doesn't crash.
        Problem reported by Nelson H. F. Beebe in
        <http://lists.gnu.org/archive/html/emacs-devel/2013-03/msg00021.html>.

2013-03-05  Dmitry Antipov  <dmantipov@yandex.ru>

        * composite.c (get_composition_id, fill_gstring_header):
        Use make_uninit_vector where appropriate.
        * font.c (Ffont_get_glyphs, build_style_table): Likewise.
        * xselect.c (clean_local_selection_data): Likewise.

2013-03-04  Paul Eggert  <eggert@cs.ucla.edu>

        Fix misuse of ImageMagick that caused core dump (Bug#13846).
        * image.c (imagemagick_load_image): Calculate height and width
        after flattening the image, not before.

2013-03-04  Dmitry Antipov  <dmantipov@yandex.ru>

        * font.c (Ffont_get_glyphs): Use convenient LGLYPH_NEW.
        * ftfont.c (ftfont_shape_by_flt): Likewise.
        * w32uniscribe.c (uniscribe_shape): Likewise.

2013-03-02  Paul Eggert  <eggert@cs.ucla.edu>

        The lock for FILE is now .#FILE or .#-FILE (Bug#13807).
        The old approach, which fell back on DIR/.#FILE.0 through
        DIR/.#FILE.9, had race conditions that could not be easily fixed.
        If DIR/.#FILE is a non-symlink file, Emacs now does not create a
        lock file for DIR/FILE; that is, DIR/FILE is no longer partly
        protected by a lock if DIR/.#FILE is a non-symlink file ("partly"
        because the locking mechanism was never reliable in that case).
        This patch fixes this and other bugs discovered by a code
        inspection that was prompted by
        <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00531.html>.
        Also, this patch switches to .#-FILE (not .#FILE) on MS-Windows,
        to avoid interoperability problems between the MS-Windows and
        non-MS-Windows implementations.  MS-Windows and non-MS-Windows
        instances of Emacs now ignore each others' locks.
        * filelock.c (defined_WINDOWSNT): New constant.
        (MAKE_LOCK_NAME, fill_in_lock_file_name):
        Don't create DIR/.#FILE.0 through DIR/.#FILE.9.  Instead, create
        DIR/.#FILE symlinks on non-MS-Windows hosts, and DIR/.#-FILE
        regular files on MS-Windows hosts.
        (MAKE_LOCK_NAME, unlock_file, Ffile_locked_p):
        Use SAFE_ALLOCA to avoid problems with long file names.
        (MAX_LFINFO): Now a local constant, not a global macro.
        (IS_LOCK_FILE): Remove.
        (lock_file_1): Don't inspect errno if symlink call succeeds;
        that's not portable.
        (lock_file): Document that this function can return if lock
        creation fails.
        (lock_file): Don't access freed storage.

2013-03-02  Andreas Schwab  <schwab@linux-m68k.org>

        * lisp.h (XPNTR) [!USE_LSB_TAG]: Remove extra paren.  (Bug#13734)

2013-03-02  Paul Eggert  <eggert@cs.ucla.edu>

        * textprop.c: Use bool for booleans.
        (validate_interval_range, Fadd_text_properties)
        (Fremove_text_properties): Prefer bool to int when either works.

2013-03-02  Eli Zaretskii  <eliz@gnu.org>

        * textprop.c (Fadd_text_properties, Fremove_text_properties): If
        the interval tree changes as a side effect of calling
        modify_region, re-do processing starting from the call to
        validate_interval_range.  (Bug#13743)

2013-02-28  Eli Zaretskii  <eliz@gnu.org>

        * w32.c (sys_open): Don't reset the flags for FD in fd_info[].
        (Bug#13546).

2013-02-27  Eli Zaretskii  <eliz@gnu.org>

        * filelock.c (create_lock_file) [WINDOWSNT]: Use _sopen with
        _SH_DENYRW flag, instead of emacs_open, to deny any other process
        access to the lock file until it is written and closed.
        (Bug#13807)

2013-02-27  Paul Eggert  <eggert@cs.ucla.edu>

        * callint.c (Qcall_interactively):

        (Fadd_text_properties):
        Don't assume list length fits in int.
        (interval_has_all_properties, interval_has_some_properties)
        (interval_has_some_properties_list, add_properties, remove_properties)
        (Fadd_text_properties, Fremove_text_properties)
        (Fremove_list_of_text_properties, text_property_stickiness):
        Use bool for booleans.

        (Fremove_list_of_text_properties):
        Reindent do-while as per GNU style.

2013-02-25  Eli Zaretskii  <eliz@gnu.org>

        Implement CLASH_DETECTION for MS-Windows.

        * filelock.c [WINDOWSNT]: Include w32.h.
        (MAKE_LOCK_NAME): Don't use 'lock', it clashes with MS runtime
        function of that name.  Up-case the macro arguments.
        (IS_LOCK_FILE): New macro.
        (fill_in_lock_file_name): Use IS_LOCK_FILE instead of S_ISLNK.
        (create_lock_file): New function, with body extracted from
        lock_file_1.
        [WINDOWSNT]: Implement lock files by writing a regular file with
        the lock information as its contents.
        (read_lock_data): New function, on Posix platforms just calls
        emacs_readlinkat.
        [WINDOWSNT]: Read the lock info from the file.
        (current_lock_owner): Call read_lock_data instead of calling
        emacs_readlinkat directly.

        dostounix_filename.

        * w32proc.c (sys_kill): Support the case of SIG = 0, in which case
        just check if the process by that PID exists.

        * w32.c (sys_open): Don't reset the _O_CREAT flag if _O_EXCL is
        also present, as doing so will fail to error out if the file
        already exists.

        * makefile.w32-in ($(BLD)/filelock.$(O)): Depend on src/w32.h.

        * textprop.c (Fadd_text_properties, Fremove_text_properties)
        (Fremove_list_of_text_properties): Skip all of the intervals in
        the region between START and END that already have resp. don't
        have the requested properties, not just the first one.  Add
        assertions that the loop afterwards always modifies the
        properties.  (Bug#13743)

2013-02-25  Stefan Monnier  <monnier@iro.umontreal.ca>

        * vm-limit.c: Move most of mem-limits.h's contents here.
        (data_start): New decl.  It's OK if this is approximate,
        so simplify-away some unnecessary exactness.
        (POINTER): Remove; all uses removed.
        (data_space_start): Now char *, to avoid casts.
        (exceeds_lisp_ptr): New function, replacing the old

        * ralloc.c (SIZE, POINTER, NIL):
        * vm-limit.c (POINTER):
        Remove, replacing all uses with C89 equivalents.  These old
        symbols were present only for porting to pre-C89 platforms.

        (_sys_read_ahead): Update cp->status when failing to read serial
        communications input, so that the status doesn't stay at
        STATUS_READ_IN_PROGRESS.  (Bug#13546)

2013-02-14  Jan Djärv  <jan.h.d@swipnet.se>

        * gtkutil.c (tb_size_cb): New function.
        (xg_create_tool_bar): Connect size-allocate to tb_size_cb (Bug#13512).

2013-02-14  Stefan Monnier  <monnier@iro.umontreal.ca>

        * keyboard.c (active_maps): Fcurrent_active_maps expects a position, not
        an event.

2013-02-13  Stefan Monnier  <monnier@iro.umontreal.ca>

        * keyboard.c (syms_of_keyboard): Further tweaks of docstring.

2013-02-13  Dmitry Antipov  <dmantipov@yandex.ru>

        * font.c (font_range): Add pos_byte argument.  Adjust comment
        and break long line.
        * font.h (font_range): Adjust prototype.
        * composite.c (autocmp_chars): Pass byte position to font_range.
        Break long line.  Remove useless prototype and format comment.

2013-02-13  Glenn Morris  <rgm@gnu.org>

        * keyboard.c (input-decode-map, key-translation-map): Doc fixes.

2013-02-13  Paul Eggert  <eggert@cs.ucla.edu>

        Improve AIX port some more (Bug#13650).
        With this, it should be as good as it was in 23.3, though it's
        still pretty bad: the dumped emacs does not run.  See Mark Fleishman in
        http://lists.gnu.org/archive/html/help-gnu-emacs/2011-04/msg00287.html
        * unexaix.c (start_of_text): Remove.
        (_data, _text): Declare as char[], not int, as AIX manual suggests.
        (bias, lnnoptr, text_scnptr, data_scnptr, load_scnptr)
        (orig_load_scnptr, orig_data_scnptr):
        Now off_t, not long, since they are file offsets.
        (make_hdr): Use _data, not start_of_data ().
        This is the key part of the fix.
        (make_hdr, unrelocate_symbols): Use off_t for file offsets.
        (unrelocate_symbols): Cast pointers to intptr_t, not to ulong.

        * pre-crt0.c (data_start): Initialize to 1.
        This ports to compilers that optimize the external declaration
        'int x = 0;' as if it were 'int x;' to shrink the executable.

        Improve AIX port (Bug#13650).
        This doesn't fix the bug, but it makes progress: Emacs builds now.
        * unexaix.c: Include inttypes.h, stdarg.h.
        (report_error, report_error_1): Mark as _Noreturn.
        (report_error): Don't report the wrong errno.
        (report_error_1): Now varargs.  All callers changed.
        (make_hdr): Use uintptr_t, not unsigned, when converting pointers
        to unsigned.  Don't use ADDR_CORRECT, as it no longer exists.
        (write_ptr): Use %p to print address rather than %lx and a cast
        to unsigned long.  Grow buffer a bit, to be safer.

2013-02-13  Eli Zaretskii  <eliz@gnu.org>

        * bidi.c (bidi_resolve_neutral): After finding the next
        non-neutral character, accept NEUTRAL_ON type as well, because
        directional control characters, such as LRE and RLE, have their
        type converted to that by bidi_resolve_weak.  This avoids aborts
        when LRE/RLE follows a run of neutrals.
        (bidi_move_to_visually_next): Assert that return value of
        bidi_peek_at_next_level is non-negative.  Negative values will
        cause an infloop.

2013-02-13  Paul Eggert  <eggert@cs.ucla.edu>

        Minor getenv-related fixes.
        * callproc.c (Fcall_process_region) [!DOS_NT]:
        Avoid unnecessary duplicate call to getenv.
        * callproc.c (init_callproc):
        * dispnew.c (init_display):
        * sysdep.c (sys_subshell):
        Omit unnecessary cast of getenv or egetenv.

2013-02-13  Juanma Barranquero  <lekktu@gmail.com>

        * makefile.w32-in ($(BLD)/filelock.$(O), $(BLD)/sysdep.$(O)):
        Update dependencies.

2013-02-12  Eli Zaretskii  <eliz@gnu.org>

        * xdisp.c (redisplay_internal): Don't set w->region_showing to the
        marker's position.
        (display_line): Set w->region_showing to the value of
        it->region_beg_charpos, not to -1.  This fixes redisplay
        optimization when cursor is moved up after M->.  (Bug#13623)
        (Bug#13626)
        (try_scrolling): Scroll text up more if point is too close to ZV
        and inside the scroll margin.  This makes sure point is moved
        outside the scroll margin in these cases.

        * window.h (struct window): region_showing can no longer be
        negative.

2013-02-11  Paul Eggert  <eggert@cs.ucla.edu>

        Tune by using memchr and memrchr.
        * doc.c (Fsnarf_documentation):
        * fileio.c (Fsubstitute_in_file_name):
        * search.c (find_newline, scan_newline):
        * xdisp.c (pos_visible_p, display_count_lines):
        Use memchr and memrchr rather than scanning byte-by-byte.
        * search.c (find_newline): Rename from scan_buffer.
        Omit first arg TARGET, as it's always '\n'.  All callers changed.

        Clean up read_key_sequence a tiny bit more.
        * keyboard.c (read_char_x_menu_prompt) [HAVE_MENUS]:
        (read_key_sequence): Remove unused locals.

2013-02-11  Stefan Monnier  <monnier@iro.umontreal.ca>

        Clean up read_key_sequence a bit; reread active keymaps after first event.
        * keyboard.c (read_char, read_char_x_menu_prompt)
        (read_char_minibuf_menu_prompt):
        Replace nmaps+maps with a single `map' arg.
        (follow_key): Operate on a single map.
        (active_maps): New function.
        (test_undefined): Also return true for nil bindings.
        (read_key_sequence): Use active_maps to replace the arrays of keymaps with
        a single (composed) keymap.  Remember `first_event' to choose the right
        set of active keymaps.  Recompute the set of keymaps after receiving
        the first event.  Remove GOBBLE_FIRST_EVENT.
        (syms_of_keyboard): Remove inhibit_local_menu_bar_menus.
        * keyboard.h (read_char): Update declaration.
        * lread.c (read_filtered_event): Adjust call to read_char.

2013-02-11  Eli Zaretskii  <eliz@gnu.org>

        * xdisp.c (move_it_vertically_backward, move_it_by_lines):
        Don't use the limitation on backwards movement when lines are truncated
        in the window.  (Bug#13675)

2013-02-11  Dmitry Antipov  <dmantipov@yandex.ru>

        * marker.c (set_marker_internal): If desired position is passed
        as a marker, avoid call to buf_charpos_to_bytepos.
        * window.c (Fset_window_point): Omit redundant type checking.
        (Fset_window_start): Likewise.  Format comment.
        (window_scroll_pixel_based): Use set_marker_restricted_both
        with character and byte positions obtained from an iterator.
        (Fset_window_configuration): Use set_marker_restricted_both.
        * xdisp.c (message_dolog): Likewise.

2013-02-10  Eli Zaretskii  <eliz@gnu.org>

        * xdisp.c (move_it_vertically_backward, move_it_by_lines):
        When text lines are longer than window's screen lines, don't move back
        too far.  This speeds up some redisplay operations.  (Bug#13675)

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

        * syntax.c (scan_sexps_forward): Fix byte position calculation
        Bug#13664 (a.k.a Bug#13667) introduced with 2013-02-08 change.

2013-02-10  Paul Eggert  <eggert@cs.ucla.edu>

        * fileio.c (Fexpand_file_name): Omit confusing pointer comparison
        that was not needed.

2013-02-09  Paul Eggert  <eggert@cs.ucla.edu>

        Minor hashing refactoring.
        * fns.c (SXHASH_REDUCE): Move to lisp.h.
        (sxhash_float): Return EMACS_UINT, for consistency with the other
        hash functions.
        * lisp.h (INTMASK): Now a macro, since SXHASH_REDUCE is now a
        non-static inline function and therefore can't use static vars.
        (SXHASH_REDUCE): Move here from fns.c, and make it inline.
        * profiler.c (hashfn_profiler): Use SXHASH_REDUCE, to be consistent
        with the other hash functions.

2013-02-09  Eli Zaretskii  <eliz@gnu.org>

        * callproc.c (Fcall_process_region) [WINDOWSNT]: Make sure the
        XXXXXX part of the temporary file pattern is not downcased even
        when w32-downcase-file-names is non-nil.  (Bug#13661)

        * xdisp.c (decode_mode_spec): Remove handling of %t.

        * msdos.c (careadlinkatcwd): Remove.

2013-02-08  Stefan Monnier  <monnier@iro.umontreal.ca>

        * lread.c (skip_dyn_bytes): New function (bug#12598).
        (read1): Use it.  Use getc instead of READCHAR to read bytes.
        (load_each_byte): Remove.  Update users.

2013-02-08  Dmitry Antipov  <dmantipov@yandex.ru>

        * search.c (scan_buffer): Calculate end byte position just once.
        (scan_newline): Do not recalculate start_byte.
        (search_command): Use eassert.
        * syntax.c (struct lisp_parse_state): New member location_byte.
        (scan_sexps_forward): Record from_byte and avoid redundant
        character to byte position calculation ...
        (Fparse_partial_sexp): ... here.  Break too long line.

2013-02-08  Dmitry Antipov  <dmantipov@yandex.ru>

        * lisp.h (make_uninit_vector): New function.
        * alloc.c (Fvector, Fmake_byte_code):
        * ccl.c (Fregister_ccl_program):
        * charset.c (Fdefine_charset_internal, define_charset_internal):

        * fontset.c (FONT_DEF_NEW, Fset_fontset_font):
        * ftfont.c (ftfont_shape_by_flt):
        * indent.c (recompute_width_table):
        * nsselect.m (clean_local_selection_data):
        * syntax.c (init_syntax_once):
        * w32unsubscribe.c (uniscribe_shape):
        * window.c (Fcurrent_window_configuration):
        * xfaces.c (Fx_family_fonts):
        * xselect.c (selection_data_to_lisp_data): Use it.

2013-02-07  Dmitry Antipov  <dmantipov@yandex.ru>

        * coding.c (Fdefine_coding_system_internal): Use AREF where
        argument is known to be a vector.
        * fns.c (Flocale_info): Likewise for ASET.
        * xselect.c (selection_data_to_lisp_data): Likewise for ASET.
        * w32fns.c (w32_parse_hot_key): Likewise for ASIZE and AREF.

2013-02-05  Jan Djärv  <jan.h.d@swipnet.se>

        * nsmenu.m (update_frame_tool_bar): Check for negative tool bar
        height.

        * nsterm.h (HAVE_NATIVE_FS): Define if OSX => 10.7.
        (EmacsView): Add fs_is_native, fsIsNative, isFullscreen and
        updateCollectionBehaviour.

        * nsterm.m (NEW_STYLE_FS): Remove.
        (ns_last_use_native_fullscreen): New variable.
        (x_make_frame_visible): Replace NEW_STYLE_FS with isFullscreen.
        (x_set_window_size): Do not take title bar and tool bar into account
        if isFullscreen returns YES.
        (ns_fullscreen_hook): Replace NEW_STYLE_FS with isFullscreen.
        (check_native_fs): New function.
        (ns_select, ns_read_socket): Call check_native_fs if HAVE_NATIVE_FS.
        (ns_term_init): Remove NEW_STYLE_FS.
        (updateFrameSize:, windowWillResize:toSize:): Only adjust for title bar
        and tool bar if isFullscreen returns NO.
        (windowDidResize:): Replace NEW_STYLE_FS with fsIsNative.
        (initFrameFromEmacs:): Initialize fs_is_native.  Replace NEW_STYLE_FS
        with HAVE_NATIVE_FS.
        (window:willUseFullScreenPresentationOptions:): New method.
        (windowDidEnterFullScreen:): Replace NEW_STYLE_FS with fsIsNative.
        Hide toolbar if not enabled (Bug#13444).
        (windowDidExitFullScreen:): Call updateCollectionBehaviour.
        Restore tool bar if enabled, hide it otherwise (Bug#13444).
        (fsIsNative, isFullscreen, updateCollectionBehaviour): New methods.
        (toggleFullScreen:): If fs_is_native, call toggleFullScreen on
        window.  Do no set FRAME_EXTERNAL_TOOL_BAR (f) to 0.
        Check FRAME_EXTERNAL_TOOL_BAR (f) before restoring
        FRAME_TOOLBAR_HEIGHT (f).  Call updateFrameSize when going non-fs.
        (syms_of_nsterm): Add ns-use-native-fullscreen.

2013-02-04  Paul Eggert  <eggert@cs.ucla.edu>

        * fileio.c (Qchoose_write_coding_system): Now static.

2013-02-04  Eli Zaretskii  <eliz@gnu.org>

        * xdisp.c (window_buffer_changed): region_showing can be negative,
        which still means region is being displayed.
        (redisplay_internal): Resurrect code that forced redisplay of the
        whole window when showing region and the mark has changed.
        Record the new mark position to allow redisplay optimizations.
        (display_line): If it->region_beg_charpos is non-zero, set the
        window's region_showing member to -1.  (Bug#13623)  (Bug#13626)

        * window.h (struct window) <region_showing>: Declare ptrdiff_t,
        not bitfield of 1 bit.

2013-02-03  Daniel Colascione  <dancol@dancol.org>

        * emacs.c: Use execvp, not execv, when DAEMON_MUST_EXEC, so that
        daemon mode works on cygw32 when Emacs is installed and not just
        during development.

2013-02-02  Paul Eggert  <eggert@cs.ucla.edu>

        Avoid file time stamp bug on MS-Windows (Bug#13149).
        * fileio.c (Fwrite_region): Don't use the heuristic on empty files,
        as FAT32 doesn't update time stamps when truncating them.
        Also, check that a file time stamp is not a multiple of 100 ns;
        this should catch all instances of the problem on MS-Windows,
        as its native file system resolution is 100 ns or worse, and
        checking for a non-multiple of 100 ns should impose only a small
        overhead on systems with ns resolution.

2013-02-02  Eli Zaretskii  <eliz@gnu.org>

        Avoid encoding file names on MS-Windows when they need to be run
        through dostounix_filename.
        * w32.c (normalize_filename): Accept an additional argument
        MULTIBYTE; if non-zero, traverse the file name by bytes and don't
        downcase it even if w32-downcase-file-names is non-nil.
        (dostounix_filename): Accept an additional argument MULTIBYTE and
        pass it to normalize_filename.
        (emacs_root_dir): Adjust.

        * msdos.h (dostounix_filename): Adjust prototype.

        * w32.h (dostounix_filename): Adjust prototype.

        * msdos.c (dostounix_filename): Accept an additional argument and
        ignore it.
        (init_environment): Adjust callers of dostounix_filename.

        * fileio.c (Ffile_name_directory, file_name_as_directory)
        (directory_file_name, Fexpand_file_name)
        (Fsubstitute_in_file_name): [DOS_NT] Adjust call to
        dostounix_filename.
        [WINDOWSNT]: Downcase file names if w32-downcase-file-names is
        non-nil.
        (Fsubstitute_in_file_name): [DOS_NT] Don't downcase environment
        variables, as egetenv is case-insensitive for DOS_NT.

        * dired.c (file_name_completion): Don't call Fdirectory_file_name
        with an encoded file name.

        * w32proc.c (Fw32_short_file_name, Fw32_long_file_name):
        Adjust calls to dostounix_filename.

        * w32fns.c (Fx_file_dialog): Adjust call to dostounix_filename.

        * unexw32.c (unexec): Adjust call to dostounix_filename.

        * termcap.c (tgetent) [MSDOS]: Adjust call to dostounix_filename.

        * emacs.c (decode_env_path) [DOS_NT]: Adjust call to
        dostounix_filename.

        * callproc.c (Fcall_process) [MSDOS]: Adjust call to
        dostounix_filename.

        * callproc.c (Fcall_process): Make sure program name in PATH and
        new_argv[0] is encoded, if needed.  Otherwise, un-encoded string
        is passed to exec/spawnve, which fails unless the file-name
        encoding is UTF-8.

        * w32proc.c (sys_spawnve): Make sure escape_char is initialized,
        even if w32-quote-process-args is nil.

2013-02-01  Paul Eggert  <eggert@cs.ucla.edu>

        Fix timestamp bug when write-region appends nothing (Bug#13149).
        * fileio.c (Fwrite_region): When neither O_EXCL nor O_TRUNC is used,
        the file's time stamp doesn't change if Emacs happens to write nothing
        to the file, and on a buggy file system this could cause Emacs to
        incorrectly infer that the file system doesn't have the bug.
        Avoid this problem by inhibiting the inference in this case.

2013-02-01  Dmitry Antipov  <dmantipov@yandex.ru>

        * window.h (struct window): Convert base_line_number, base_line_pos
        and column_number_displayed members from Lisp_Object to ptrdiff_t.
        Convert region_showing member from Lisp_Object to bitfield.
        Remove sequence_number member.  Adjust comments.
        * window.c (sequence_number): Remove.
        (make_window): Initialize column_number_displayed.
        * print.c (print_object): Follow the printed representation of
        frames and print window pointer to distinguish between windows.
        (adjust_window_count): Invalidate base_line_pos.  Adjust comment.
        * xdisp.c (wset_base_line_number, wset_base_line_pos)
        (wset_column_number_displayed, wset_region_showing): Remove.
        (window_buffer_changed, mode_line_update_needed, redisplay_internal)
        (try_scrolling, try_cursor_movement, redisplay_window)
        (try_window_reusing_current_matrix, try_window_id, display_line)
        (display_mode_lines, decode_mode_spec): Adjust users.
        * .gdbinit (pwinx): Do not print sequence_number.

2013-02-01  Paul Eggert  <eggert@cs.ucla.edu>

        Use fdopendir, fstatat and readlinkat, for efficiency (Bug#13539).
        * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): Remove.
        * dired.c: Include <fcntl.h>.
        (open_directory): New function, which uses open and fdopendir
        rather than opendir.  DOS_NT platforms still use opendir, though.
        (directory_files_internal, file_name_completion): Use it.
        (file_attributes): New function, with most of the old Ffile_attributes.
        (directory_files_internal, Ffile_attributes): Use it.
        (file_attributes, file_name_completion_stat): First arg is now fd,
        not dir name.  All uses changed.  Use fstatat rather than lstat +
        stat.
        (file_attributes): Use emacs_readlinkat rather than Ffile_symlink_p.
        * fileio.c: Include <allocator.h>, <careadlinkat.h>.
        (emacs_readlinkat): New function, with much of the old
        Ffile_symlink_p, but with an fd argument for speed.
        It uses readlinkat rather than careadlinkatcwd, so that it
        need not assume the working directory.
        (Ffile_symlink_p): Use it.
        * filelock.c (current_lock_owner): Use emacs_readlinkat
        rather than emacs_readlink.
        * lisp.h (emacs_readlinkat): New decl.
        (READLINK_BUFSIZE, emacs_readlink): Remove.
        * sysdep.c: Do not include <allocator.h>, <careadlinkat.h>.
        (emacs_norealloc_allocator, emacs_readlink): Remove.
        This stuff is moved to fileio.c.
        * w32.c (fstatat, readlinkat): New functions.

        * xdisp.c (message_dolog): Adjust users to call insert_1_both.

2013-01-25  Eli Zaretskii  <eliz@gnu.org>

        * w32.c (max_filename_mbslen): New function.
        (normalize_filename, readdir): Use it to detect locales where ANSI
        encoding of file names uses a double-byte character set (DBCS).
        If a DBCS encoding is used, advance by characters using
        CharNextExA, instead of incrementing a 'char *' pointer.
        Use _mbslwr instead of _strlwr.  (Bug#13515)

        * w32heap.c (allocate_heap) [!_WIN64]: Decrease the initial
        request of memory reservation to 1.7GB.  (Bug#13065)

        Avoid redundant calls to strlen.

2013-01-24  Dmitry Antipov  <dmantipov@yandex.ru>

        Drop async_visible and async_iconified fields of struct frame.
        This is possible because async input is gone; for details, see

        * frame.h (struct frame): Remove async_visible and async_iconified
        members, convert garbaged to unsigned bitfield.  Adjust comments.
        (FRAME_SAMPLE_VISIBILITY): Remove.  Adjust all users.
        (SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED): New macros.
        * frame.c, gtkutil.c, term.c, w32fns.c, window.c, xdisp.c:
        Consistently use SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED,
        FRAME_VISIBLE_P and FRAME_ICONIFIED_P macros where appropriate.
        * w32term.c: Ditto.
        (w32_read_socket): Save iconified state to generate DEICONIFY_EVENT
        properly.  Likewise for obscured.

        in http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00555.html.

2013-01-23  Stefan Monnier  <monnier@iro.umontreal.ca>

        * xdisp.c (message2, message2_nolog): Remove functions.
        (message3, message3_nolog): Extract nbytes and multibyteness directly
        from the string.  Change all callers.
        (message3_nolog): Don't set message_enable_multibyte since set_message
        will reset it anyway.
        (message1, message1_nolog): Use message3.
        (vmessage): Use a stack allocated buffer rather than f->message_buf.
        (with_echo_area_buffer): Remove last two arguments.  Update all callers.
        (set_message): Drop all but the second arg, which has to be a string.
        (set_message_1): Simplify now that we know that a1 is NULL and the
        second arg is a string.
        * frame.h (struct frame): Remove `message_buf' field.
        Use glyphs_initialized_p instead.

        * insdel.c (prepare_to_modify_buffer): Force redisplay if
        hidden buffer is prepared to modification (Bug#13164).

2013-01-22  Dmitry Antipov  <dmantipov@yandex.ru>

        * window.h (struct window): Change window_end_valid member from

2013-01-22  Dmitry Antipov  <dmantipov@yandex.ru>

        * xdisp.c (mark_window_display_accurate): Simplify the loop
        assuming that the only one of vchild, hchild or buffer window
        slots is non-nil.  Call mark_window_display_accurate_1 for
        the leaf windows only.
        (mark_window_display_accurate_1): Always assume leaf window.
        Adjust comment.

2013-01-22  Paul Eggert  <eggert@cs.ucla.edu>

        * emacs.c (Qkill_emacs_hook): Now static.

        * fileio.c (Finsert_file_contents): Simplify.
        Remove unnecessary assignments and tests.

2013-01-21  Eli Zaretskii  <eliz@gnu.org>

        * w32.c (acl_set_file): Don't test for errors unless
        set_file_security returns FALSE.  Avoids spurious errors when
        saving files.

2013-01-21  Dmitry Antipov  <dmantipov@yandex.ru>

        * fileio.c (Finsert_file_contents): Revert code introduced at
        2013-01-18 in favor of the simpler and generally better fix.
        Save stack space by removing 'buffer' and reusing 'read_buf'
        where appropriate.

2013-01-19  Paul Eggert  <eggert@cs.ucla.edu>

        * lisp.h (eabs): Define unconditionally (Bug#13419).
        The old "#if !defined (eabs)" was an unnecessary revenant of back
        when this macro was called "abs".  Document 'eabs' better.

2013-01-19  Glenn Morris  <rgm@gnu.org>

        * fns.c (Frandom): Doc fix.

2013-01-19  Eli Zaretskii  <eliz@gnu.org>

        * editfns.c (get_pos_property): Use SAFE_ALLOCA_LISP, to avoid
        segfault when there are lots of overlays.

        * buffer.c (sort_overlays): Use SAFE_NALLOCA, to avoid segfault
        when there are lots of overlays.
        See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00421.html
        for the details and a way to reproduce.

2013-01-19  Paul Eggert  <eggert@cs.ucla.edu>

        * fileio.c: Use O_APPEND to append.
        This corresponds better to the natural interpretation of "append",
        and avoids the need to open the output file twice, or to invoke
        lseek when APPEND is neither nil nor a number.
        This relies on POSIX 1003.1-1988 or later, which is OK nowadays.
        (Fwrite_region): Simplify.  Use O_APPEND instead of opening the
        file possibly twice, and lseeking to its end; this avoids the
        need to lseek on non-regular files.  Do not use O_EXCL and O_TRUNC
        at the same time: the combination is never needed and apparently
        it doesn't work with DOS_NT.

        Fix size bug on DOS_NT introduced by CIFS workaround (Bug#13149).
        * fileio.c (Fwrite_region): Use O_BINARY in checking code, too.

        Allow floating-point file offsets.
        Problem reported by Vitalie Spinu in
        <http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00411.html>.
        * fileio.c (emacs_lseek): Remove.
        (file_offset): New function.
        (Finsert_file_contents, Fwrite_region): Use it.

2013-01-19  Chong Yidong  <cyd@gnu.org>

        * emacs.c (Fkill_emacs): Set waiting_for_input to 0 to avoid
        aborting on Fsignal (Bug#13289).

2013-01-19  Eli Zaretskii  <eliz@gnu.org>

        * w32.c (acl_set_file): Treat ERROR_ACCESS_DENIED from
        set_file_security as failure due to insufficient privileges.
        Reported by Fabrice Popineau <fabrice.popineau@supelec.fr>.
        (fstat): Return owner and group like 'stat' and 'lstat' do.

2013-01-19  Paul Eggert  <eggert@cs.ucla.edu>

        Work around bug in CIFS and vboxsf file systems (Bug#13149).
        The bug was observed on Ubuntu operating inside a virtual machine,
        editing files mounted via CIFS or vboxsf from the MS Windows 7 host.
        The workaround introduces a race condition on non-buggy hosts,
        but it's an unlikely race and anyway there's a nearly identical
        nearby race that can't be fixed.
        * fileio.c (valid_timestamp_file_system, timestamp_file_system):
        New static vars.
        (Fwrite_region): Test for file system time stamp bug.
        (init_fileio): New function.
        * lisp.h (init_fileio): Declare it.
        * emacs.c (main): Call it.

        * fileio.c (Finsert_file_contents): Simplify new diagnostic
        and make it more consistent with other stat-failure diagnostics.

2013-01-18  Dmitry Antipov  <dmantipov@yandex.ru>

        Fix crash when inserting data from non-regular files.
        See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00406.html
        for the error description produced by valgrind.
        * fileio.c (read_non_regular): Rename to read_contents.
        Free Lisp_Save_Value object used to pass parameters.
        (read_non_regular_quit): Rename to read_contents_quit.
        (Finsert_file_contents): Redesign internal file reading loop to adjust
        gap and end positions after each read and so help make_gap to work
        properly.  Do not signal an I/O error too early and so do not leave
        not yet decoded characters in a buffer, which was the reason of
        redisplay crash.  Use list2 to build return value.  Adjust comments.

2013-01-17  Paul Eggert  <eggert@cs.ucla.edu>

        Close a race when statting and reading files (Bug#13149).
        * fileio.c (Finsert_file_contents): Use open+fstat, not stat+open.
        This avoids a race if the file is renamed between stat and open.
        This race is not the problem originally noted in Bug#13149;
        see <http://bugs.gnu.org/13149#73> and later messages in the thread.

2013-01-17  Dmitry Antipov  <dmantipov@yandex.ru>

        * lisp.h (toplevel): Add comment about using Lisp_Save_Value
        objects, related functions and macros.

        (non_regular_nbytes): Remove.
        (Finsert_file_contents): Convert trytry to ptrdiff_t.
        Use format_save_value to pass parameters to read_non_regular.
        (read_non_regular): Use XSAVE_ macros to extract parameters.
        Adjust comment.
        * xmenu.c (xmenu_show) [!USE_X_TOOLKIT && !USE_GTK]: Use
        format_save_value.
        (pop_down_menu) [!USE_X_TOOLKIT && !USE_GTK]: Adjust user.

        object with the specified internal structure.
        (make_save_value): Reimplement using format_save_value.
        * editfns.c (save_excursion_save): Use format_save_value.
        (save_excursion_restore): Use XSAVE_OBJECT.

2013-01-14  Paul Eggert  <eggert@cs.ucla.edu>

        Avoid needless casts with XSAVE_POINTER.
        * alloc.c (mark_object) [GC_MARK_STACK]:

2013-01-11  Dmitry Antipov  <dmantipov@yandex.ru>

        Avoid unnecessary byte position calculation for the gap movement.
        Since all users of move_gap do CHAR_TO_BYTE for other purposes
        anyway, all of them should use move_gap_both instead.
        * lisp.h (move_gap): Remove prototype.
        * insdel.c (move_gap): Remove.
        (move_gap_both): Add eassert.

        New functions.
        * term.c (init_tty): Use them instead of rolling our own code.
        * sysdep.c (tcsetpgrp_without_stopping): Likewise.  Here, this
        switches from 'signal' to 'pthread_sigmask', which is safer in
        multithreaded applications.
        * term.c (Fresume_tty): Don't bother dissociating if O_IGNORE_CTTY,
        which has already arranged for that.
        (dissociate_if_controlling_tty): If setsid fails, fall back on TIOCNOTTY.
        This is the main part of the bug fix.

        right-fringe-width, scroll-bar-width and buffer-display-count.
        Use Qstringp for default-directory, buffer-file-name,
        buffer-file-truename and buffer-auto-save-file-name.  Use Qfloatp for
        scroll-up-aggressively and scroll-down-aggressively.  Use Qnumberp for
        line-spacing.
        * data.c (store_symval_forwarding): Adjust to call the predicate.

        GAP_BYTES_DFL and GAP_BYTES_MIN.  Adjust comment.

2013-01-08  Juri Linkov  <juri@jurta.org>

2013-01-06  Chong Yidong  <cyd@gnu.org>

        * keyboard.c (echo_add_char): New function, factored out from

        empty (Bug#13255).
        (echo_char): Use it.
        (read_key_sequence): When echoing mock input, ensure that the
        trailing dash is properly added.

2013-01-05  Eli Zaretskii  <eliz@gnu.org>

        * xdisp.c (dump_glyph): Align glyph data better.  Use "pD" instead
        of a non-portable "t" to print ptrdiff_t values.  Allow up to 9
        digits for buffer positions, before misalignment starts.
        Display "0" for integer "object" field.
        (dump_glyph_row): Adapt the header line to changes in dump_glyph.
        Display the newline glyph more unambiguously.

        * term.c (tty_ins_del_lines):
        * xterm.c (x_draw_image_foreground, x_draw_image_foreground_1):
        Use eabs (x) rather than open-coding it as (x < 0 ? -x : x).

2012-12-31  Eli Zaretskii  <eliz@gnu.org>

        * w32.c (unsetenv): Set up the string passed to _putenv
        correctly.
        See http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00863.html
        for the bug this caused.

2012-12-30  Paul Eggert  <eggert@cs.ucla.edu>

        * coding.c (Qmac): Now static.

2012-12-30  Jan Djärv  <jan.h.d@swipnet.se>

        * gtkutil.c (TOOLBAR_TOP_WIDGET): New macro.
        (xg_pack_tool_bar): Use TOOLBAR_TOP_WIDGET, condition out use of

        toolbar_is_packed to true.
        (xg_update_tool_bar_sizes): Use widget returned by TOOLBAR_TOP_WIDGET.

        by TOOLBAR_TOP_WIDGET.
        (xg_change_toolbar_position): Use widget returned by TOOLBAR_TOP_WIDGET.
        Check toolbar_is_packed.
        (xg_have_tear_offs, tearoff_remove, tearoff_activate): Condition on
        HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
        (xg_have_tear_offs): When ! HAVE_GTK_TEAROFF_MENU_ITEM_NEW, return
        false.
        (create_menus): Create tearoff only if HAVE_GTK_TEAROFF_MENU_ITEM_NEW.

        (xg_initialize): Initialize xg_detached_menus only if
        HAVE_GTK_TEAROFF_MENU_ITEM_NEW.

        * xterm.h (struct x_output): Surround handlebox_widget with
        #ifdef HAVE_GTK_HANDLE_BOX_NEW.  toolbar_is_packed is new,
        toolbar_in_hbox is bool.

2012-12-30  Andreas Schwab  <schwab@linux-m68k.org>

        * src/Makefile.in (TEMACS_LDFLAGS2): Remove.
        (LIBS_GNUSTEP): Define.
        (LIBES): Add $(LIBS_GNUSTEP).
        (temacs$(EXEEXT)): Use $(LDFLAGS) instead of $(TEMACS_LDFLAGS2).

2012-12-30  Eli Zaretskii  <eliz@gnu.org>

        * xdisp.c (set_cursor_from_row): Don't confuse a truncation or
        continuation glyph on a TTY with an indication of an empty line.
        (Bug#13277)

2012-12-29  Eli Zaretskii  <eliz@gnu.org>

        * fileio.c (Fset_file_selinux_context, Fset_file_acl): Return t if
        file's SELinux context or ACLs successfully set, nil otherwise.
        (Bug#13298)
        (Fcopy_file) [WINDOWSNT]: Improve diagnostics when CopyFile fails.

        * w32proc.c (reader_thread): Avoid passing NULL handles to

        Port EXTERNALLY_VISIBLE to Clang 3.2.
        * conf_post.h (__has_attribute): New macro.
        (EXTERNALLY_VISIBLE): Use it.  This ports to Clang 3.2.

2012-12-27  Glenn Morris  <rgm@gnu.org>

        * cygw32.c (Fcygwin_convert_file_name_to_windows)
        (Fcygwin_convert_file_name_from_windows): Doc fixes.

2012-12-27  Eli Zaretskii  <eliz@gnu.org>

        * fileio.c (file_name_as_directory, directory_file_name):
        Accept an additional argument MULTIBYTE to indicate whether the input C
        came from a multibyte or a unibyte Lisp string; all callers
        adjusted.  Don't assume the input string is always multibyte.
        (Bug#13262)
        (Ffile_name_directory) [DOS_NT]: Handle unibyte strings correctly:
        don't ENCODE_FILE them, and return a unibyte string if the input
        was unibyte.
        (Fexpand_file_name): Don't mix unibyte with multibyte strings, and
        don't assume the input strings will always be multibyte.  If the
        input strings are multibyte, decode strings obtained from C
        library functions.

2012-12-26  Dmitry Antipov  <dmantipov@yandex.ru>

        * lisp.h (toplevel): Add two notices to the comment about
        defining a new Lisp data type.
        * print.c (print_object): If Lisp_Save_Value object's pointer
        is the address of a memory area containing Lisp_Objects, try
        to print them.
        * alloc.c (valid_lisp_object_p): Adjust comment.

2012-12-26  Dmitry Antipov  <dmantipov@yandex.ru>

        * keyboard.c (record_asynch_buffer_change): Initialize an event
        only if it's really needed.
        * frame.h (enum output_method): Remove output_mac member since
        it's a leftover from the deleted code.
        * frame.c (Fframep): Adjust user here ...
        * terminal.c (Fterminal_live_p): ... and here.
        * coding.c (Qmac): Now here because it's only used to denote
        end-of-line encoding type.
        (syms_of_coding): DEFSYM it.
        * frame.h (Qmac): Remove duplicated declaration.

2012-12-26  Paul Eggert  <eggert@cs.ucla.edu>

        * window.c (select_window_1): Now static, since it's used only here.

2012-12-25  Eli Zaretskii  <eliz@gnu.org>

        * window.c (window_body_cols): Subtract display margins from the
        window body width on TTYs as well.  See
        http://lists.gnu.org/archive/html/help-gnu-emacs/2012-12/msg00317.html
        for the original report.

2012-12-25  Dmitry Antipov  <dmantipov@yandex.ru>

        * xdisp.c (redisplay_window): Remove inner local variable
        because the outer shadowed one has the same meaning.
        * xterm.h (struct x_output): Remove toolbar_detached member since it's
        set but never used.
        * gtkutil.c (xg_tool_bar_detach_callback, xg_tool_bar_attach_callback)
        (xg_create_tool_bar): Adjust users.

2012-12-24  Dmitry Antipov  <dmantipov@yandex.ru>

        * buffer.h (BUF_COMPACT): New macro to follow the common style.
        * buffer.c (Fget_buffer_create): Use it to set compact field of
        struct buffer_text to avoid accessing an uninitialized value
        when compact_buffer is called for the first time.
        (compact_buffer): Use convenient BUF_COMPACT and BUF_MODIFF.
        (Fset_buffer_modified_p): Use buffer_window_count to check
        whether the buffer is displayed in some window.
        * xdisp.c (message_dolog): Likewise.

2012-12-23  Eli Zaretskii  <eliz@gnu.org>

        * w32.c (acl_set_file): If setting the file security descriptor
        fails, and the new DACL is identical to the existing one, silently
        return success.  This fixes problems for users backing up their
        own files without having the necessary privileges for setting
        security descriptors.

        * w32proc.c (reader_thread): Do not index fd_info[] with negative
        values.
        (reader_thread): Exit when cp->status becomes STATUS_READ_ERROR
        after WaitForSingleObject returns normally.  This expedites reader
        thread shutdown when delete_child triggers it.
        (reap_subprocess): More accurate commentary for why we call
        delete_child only when cp->fd is negative.

        * w32.c (sys_close): Do not call delete_child on a subprocess
        whose handle is not yet closed.  Instead, set its file descriptor
        to a negative value, so that reap_subprocess will call
        delete_child on that subprocess when its SIGCHLD arrives.
        This avoids closing handles used for communications between sys_select
        and reader_thread, which doesn't give sys_select a chance to
        notice that the process exited and invoke the SIGCHLD handler for
        it.

2012-12-23  Jan Djärv  <jan.h.d@swipnet.se>

        * nsfns.m (Fns_do_applescript): Run event loop until script has
        been executed (Bug#12969).
        (ns_run_ascript): Chech as_script for nil, set to nil after
        executing script.

2012-12-22  Martin Rudalics  <rudalics@gmx.at>

        (w32_create_terminal): Plug it into the terminal's fullscreen_hook.

2012-12-21  Eli Zaretskii  <eliz@gnu.org>

        * fileio.c (Finsert_file_contents): Doc fix.

        * w32proc.c (new_child, delete_child, find_child_pid): For a
        subprocess, consider its slot being in use as long as its process
        handle (procinfo.hProcess) is not NULL.  This avoids reusing the
        slot when a new process is started immediately after killing
        another one, without waiting enough time for the first process to
        be reaped and resources allocated for it be orderly freed.
        (Bug#13086)
        Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.

2012-12-21  Chong Yidong  <cyd@gnu.org>

        * buffer.c (Fset_buffer_major_mode): Doc fix (Bug#13231).

        * fns.c (Fcompare_strings): Doc fix (Bug#13081).

2012-12-21  Eli Zaretskii  <eliz@gnu.org>

        * w32.c (get_name_and_id): Always pass NULL as the first argument
        of lookup_account_sid.  Avoids crashes with UNC file names that
        refer to DFS domains, not to specific machine names.  (Bug#12621)
        Remove now unused argument FNAME; all callers changed.
        (get_file_owner_and_group): Remove now unused argument FNAME; all
        callers changed.

2012-12-21  Chong Yidong  <cyd@gnu.org>

        * editfns.c (Finsert_char): Since read-char-by-name now signals an
        error for invalid chars, don't check for a nil return value.

2012-12-20  Dmitry Antipov  <dmantipov@yandex.ru>

        Avoid calls to CHAR_TO_BYTE if byte position is known.
        * editfns.c (make_buffer_string_both): Use move_gap_both.
        (Fbuffer_string): Use make_buffer_string_both.

        * fileio.c (Finsert_file_contents): Use move_gap_both.
        * search.c (Freplace_match): Likewise.

        * xdisp.c (redisplay_internal): Remove now-unused local.

2012-12-20  Stefan Monnier  <monnier@iro.umontreal.ca>

        * xdisp.c (select_frame_for_redisplay, ensure_selected_frame): Remove.
        (redisplay_internal): Don't bother selecting the frame to get the
        proper value of frame-local variables (bug#13225).

2012-12-20  Dmitry Antipov  <dmantipov@yandex.ru>

        * textprop.c (set_text_properties_1): Do not allow NULL interval.
        Rename 4th argument since it may be buffer or string.  Adjust comment.
        * intervals.c (graft_intervals_info_buffer): Find an interval here.

2012-12-19  Dmitry Antipov  <dmantipov@yandex.ru>

        * coding.c (Fdetect_coding_region): Do not check start and end with
        CHECK_NUMBER_COERCE_MARKER since validate_region does that itself.
        (code_convert_region): Likewise.

2012-12-18  Eli Zaretskii  <eliz@gnu.org>

        * w32.c (acl_get_file, acl_set_file): Run the file name through
        map_w32_filename, and resolve any symlinks in the file name, like
        Posix platforms do.

        try to get accurate owner and group information from NT file

        'lstat', which don't need that information, much faster.

        * dired.c (Ffile_attributes) [WINDOWSNT]:
        Set w32_stat_get_owner_group to a non-zero value, to request accurate

        * fileio.c (Finsert_file_contents): Don't put tail into head area,
        as that confuses set-auto-coding, so insist on the head-read

        fstat shouldn't fail, and if it does fail copy-file should not proceed.

        function can't copy symlinks.  Improve quality of error message
        when attempting to copy files that are neither regular files nor
        directories.

2012-12-12  Dmitry Antipov  <dmantipov@yandex.ru>

2012-12-08  Paul Eggert  <eggert@cs.ucla.edu>

        Simplify get_lim_data.
        * vm-limit.c (get_lim_data): Combine RLIMIT_AS and RLIMIT_DATA methods.
        Remove USG and vlimit methods; no longer used these days.
        Add #error catchall just in case.

        Assume POSIX 1003.1-1988 or later for signal.h (Bug#13026).
        Exceptions: do not assume SIGCONT, SIGSTOP, SIGTSTP, SIGTTIN,
        SIGTTOU, SIGUSR1, SIGUSR2, as Microsoft platforms lack these.
        * process.c [subprocesses]: Include <c-ctype.h>, <sig2str.h>.
        (deleted_pid_list, Fdelete_process, create_process)
        (record_child_status_change, handle_child_signal, deliver_child_signal)
        (init_process_emacs, syms_of_process):
        Assume SIGCHLD is defined.
        (parse_signal): Remove.  All uses removed.
        (abbr_to_signal): New static function.
        (Fsignal_process): Use it to convert signal names to ints.
        * sysdep.c (sys_suspend) [!DOS_NT]: Use kill (0, ...) rather than
        kill (getpgrp (), ...).
        (emacs_sigaction_init): Assume SIGCHLD is defined.
        (init_signals): Assume SIGALRM, SIGCHLD, SIGHUP, SIGKILL,
        SIGPIPE, and SIGQUIT are defined.  Do not worry about SIGCLD any more.
        * syssignal.h (EMACS_KILLPG): Remove.
        All uses replaced by 'kill' with a negative pid.
        (SIGCHLD): Remove definition, as we now assume SIGCHLD.
        * w32proc.c (sys_kill): Support negative pids compatibly with POSIX.

2012-12-07  Paul Eggert  <eggert@cs.ucla.edu>

        * sysdep.c (get_child_status): Abort on internal error (Bug#13086).
        This will cause a production Emacs to dump core instead of
        infinite-looping.

2012-12-07  Dmitry Antipov  <dmantipov@yandex.ru>

        * frame.c (make_frame): Do not set window's buffer to t.
        * window.c (Fsplit_window_internal): Likewise.  Previously it was
        used to indicate that the window is being set up.  Now we use
        set_window_buffer for all new windows, so the condition in ...
        (Fset_window_buffer): ... is always true and can be removed.

2012-12-07  Dmitry Antipov  <dmantipov@yandex.ru>

        Convenient macro to check whether the buffer is hidden.
        * buffer.h (BUFFER_HIDDEN_P): New macro.
        * frame.c (make_frame): Use it.  Adjust comment.
        * buffer.c (candidate_buffer): New function.
        (Fother_buffer, other_buffer_safely): Use it.

2012-12-06  Eli Zaretskii  <eliz@gnu.org>

        * w32proc.c (waitpid): Avoid busy-waiting when called with WNOHANG
        if the child process is still running.  Instead, exit the wait
        loop and return zero.  (Bug#13086)

2012-12-06  Dmitry Antipov  <dmantipov@yandex.ru>

        * frame.h (x_char_width, x_char_height): Remove prototypes.
        * w32term.h (x_char_width, x_char_height): Likewise.
        * xfns.c (x_char_width, x_char_height): Remove.
        * w32fns.c (x_char_width, x_char_height): Likewise.
        * nsfns.c (x_char_width, x_char_height): Likewise.
        * frame.c (Fframe_char_width): Use FRAME_COLUMN_WIDTH for
        all window frames.
        (Fframe_char_height): Likewise with FRAME_LINE_HEIGHT.
        * keyboard.c (command_loop_1): Remove prototype.
        (command_loop_2, top_level_1): Add static to match prototype.

2012-12-06  Paul Eggert  <eggert@cs.ucla.edu>

        Fix a recently-introduced delete-process race condition.
        * callproc.c, process.h (record_kill_process):
        New function, containing part of the old call_process_kill.
        (call_process_kill): Use it.
        This does not change call_process_kill's behavior.
        * process.c (Fdelete_process): Use record_kill_process to fix a
        race condition that could cause Emacs to lose track of a child.

2012-12-06  Dmitry Antipov  <dmantipov@yandex.ru>

        Avoid code duplication between prev_frame and next_frame.
        * frame.c (candidate_frame): New function.  Add comment.
        (prev_frame, next_frame): Use it.  Adjust comment.

2012-12-06  Eli Zaretskii  <eliz@gnu.org>

        * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
        fails, signal an error instead of continuing with an empty
        string.  (Bug#13079)
        Encode expanded temp file pattern before passing it to mkstemp or
        mktemp.

        * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
        Encode the file name before passing it to dostounix_filename, in
        case it will downcase it (under w32-downcase-file-names).
        (Bug#12933)

2012-12-05  Paul Eggert  <eggert@cs.ucla.edu>

        Minor call-process cleanups.
        * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
        at the same time as other platforms, to simplify analysis.
        No need for fd0_volatile since we have synch_process_fd.
        Avoid needless emacs_close; arg is always negative.

2012-12-04  Andreas Schwab  <schwab@linux-m68k.org>

        * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous
        processes.

2012-12-04  Dmitry Antipov  <dmantipov@yandex.ru>

        * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
        member.  Adjust users.  Convert mouse_face_past_end, mouse_face_defer
        and mouse_face_hidden members to a bitfields.
        * frame.h (struct frame): Remove set-but-not-used space_width member.
        (FRAME_SPACE_WIDTH): Remove.
        * nsterm.m, w32term.c, xterm.c: Adjust users.
        * termchar.h (struct tty_display_info): Remove set-but-unused se_is_so
        member.  Adjust users.  Convert term_initted, delete_in_insert_mode,
        costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
        members to a bitfields.

2012-12-03  Paul Eggert  <eggert@cs.ucla.edu>

        Don't let call-process be a zombie factory (Bug#12980).
        Fixing this bug required some cleanup of the signal-handling code.
        As a side effect, this change also fixes a longstanding rare race
        condition whereby Emacs could mistakenly kill unrelated processes,
        and it fixes a bug where a second C-g does not kill a recalcitrant
        synchronous process in GNU/Linux and similar platforms.
        The patch should also fix the last vestiges of Bug#9488,
        a bug which has mostly been fixed on the trunk by other changes.
        * callproc.c, process.h (synch_process_alive, synch_process_death)
        (synch_process_termsig, sync_process_retcode):
        Remove.  All uses removed, to simplify analysis and so that
        less consing is done inside critical sections.
        * callproc.c (call_process_exited): Remove.  All uses replaced
        with !synch_process_pid.
        * callproc.c (synch_process_pid, synch_process_fd): New static vars.
        These take the role of what used to be in unwind-protect arg.
        All uses changed.
        (block_child_signal, unblock_child_signal):
        New functions, to avoid races that could kill innocent-victim processes.
        (call_process_kill, call_process_cleanup, Fcall_process): Use them.
        (call_process_kill): Record killed processes as deleted, so that
        zombies do not clutter up the system.  Do this inside a critical
        section, to avoid a race that would allow the clutter.
        (call_process_cleanup): Fix code so that the second C-g works again
        on common platforms such as GNU/Linux.
        (Fcall_process): Create the child process in a critical section,
        to fix a race condition.  If creating an asynchronous process,
        record it as deleted so that zombies do not clutter up the system.
        Do unwind-protect for WINDOWSNT too, as that's simpler in the
        light of these changes.  Omit unnecessary call to emacs_close
        before failure, as the unwind-protect code does that.
        * callproc.c (call_process_cleanup):
        * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
        * process.c (record_deleted_pid): New function, containing
        code refactored out of Fdelete_process.
        (Fdelete_process): Use it.
        (process_status_retrieved): Remove.  All callers changed to use
        child_status_change.
        (record_child_status_change): Remove, folding its contents into ...
        (handle_child_signal): ... this signal handler.  Now, this
        function is purely a handler for SIGCHLD, and is not called after
        a synchronous waitpid returns; the synchronous code is moved to
        wait_for_termination.  There is no need to worry about reaping
        more than one child now.
        * sysdep.c (get_child_status, child_status_changed): New functions.
        (wait_for_termination): Now takes int * status and bool
        interruptible arguments, too.  Do not record child status change;
        that's now the caller's responsibility.  All callers changed.
        Reimplement in terms of get_child_status.
        (wait_for_termination_1, interruptible_wait_for_termination):
        Remove.  All callers changed to use wait_for_termination.
        * syswait.h: Include <stdbool.h>, for bool.
        (record_child_status_change, interruptible_wait_for_termination):
        Remove decls.
        (record_deleted_pid, child_status_changed): New decls.
        (wait_for_termination): Adjust to API changes noted above.

        * bytecode.c, lisp.h (Qbytecode): Remove.
        No longer needed after 2012-11-20 interactive-p changes.

2012-12-03  Eli Zaretskii  <eliz@gnu.org>

        * xdisp.c (redisplay_window): If the cursor is visible, but inside
        the scroll margin, move point outside the margin.  (Bug#13055)

2012-12-03  Jan Djärv  <jan.h.d@swipnet.se>

        * gtkutil.c (my_log_handler): New function.
        (xg_set_geometry): Set log handler to my_log_handler (Bug#11177).

2012-12-03  Dmitry Antipov  <dmantipov@yandex.ru>

        * lisp.h (modify_region): Rename to...

        * textprop.c (modify_region): Now static.  Adjust users.
        * insdel.c (modify_region): Rename to...
        (modify_region_1): ...new function to work with current buffer.
        Adjust comment and users.  Use true and false for booleans.

2012-12-03  Dmitry Antipov  <dmantipov@yandex.ru>

        * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
        Add comment.
        (save_excursion_restore): Adjust to match saved data structure.
        Use free_save_value to offload some work from GC.  Drop obsolete
        #if 0 code.

2012-12-03  Chong Yidong  <cyd@gnu.org>

        * fileio.c (Vauto_save_list_file_name): Doc fix.

        builds.
        (file_dialog_callback): Make it UINT_PTR.

        * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
        with 64-bit builds.

        (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
        defined.

        * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.

2012-12-02  Paul Eggert  <eggert@cs.ucla.edu>

        Fix xpalloc confusion after memory is exhausted.
        * alloc.c (xpalloc): Comment fix.
        * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
        and signals an error, do not clear charset_table_size, as
        charset_table is still valid.
        * doprnt.c (evxprintf): Clear *BUF after freeing it.

        Use execve to avoid need to munge environ (Bug#13054).
        * callproc.c (Fcall_process):
        * process.c (create_process):
        Don't save and restore environ; no longer needed.
        * callproc.c (child_setup):
        Use execve, not execvp, to preserve environ.

        * doc.c (Fdocumentation): Re-add handling of function-documentation,
        accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).

2012-11-29  Dmitry Antipov  <dmantipov@yandex.ru>

        * xdisp.c (window_outdated): Remove eassert since it hits
        some suspicious corner cases (see Bug#13007 and Bug#13012).
        (mode_line_update_needed): New function.
        (redisplay_internal, redisplay_window): Use it.

        * callproc.c (Fcall_process): Fix vfork portability problems.
        Do not assume that fd[0], count, filefd, and save_environ survive
        vfork.  Fix bug whereby wrong errno value could be reported for
        pipe failure.  Some minor cleanups, too, as follows.  Move buf and
        bufsize to the context where they're needed.  Change new_argv to
        be of type char **, as this is more convenient and avoids casts.
        (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
        Now local constants, not macros.

2012-11-18  Kenichi Handa  <handa@gnu.org>

        (Bug#11964)

        * xdisp.c (draw_glyphs): Don't draw in mouse face if mouse

        * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
        between bpos_covered and bpos_max.  This fixes cursor display when
        several display strings follow each other.

        * .gdbinit (pgx): If the glyph's object is a string, display the
        pointer to string data, rather than the value of the string object
        itself (which barfs under CHECK_LISP_OBJECT_TYPE).

        * indent.c (Fvertical_motion): If the starting position is covered
        by a display string, return to one position before that, to avoid
        overshooting it inside move_it_to.  (Bug#12930)

2012-11-23  Dmitry Antipov  <dmantipov@yandex.ru>

        * frame.h (struct frame): Remove display_preempted member

        (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
        (DIRENTRY_NONEMPTY): Remove.  All callers now assume it's nonzero.
        * makefile.w32-in (DIR_H): Remove.  All uses replaced with
        $(NT_INC)/dirent.h.
        ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.

2012-11-22  Dmitry Antipov  <dmantipov@yandex.ru>

        * xdisp.c (window_buffer_changed): New function.
        (update_menu_bar, update_tool_bar): Use it to
        simplify large 'if' statements.
        (redisplay_internal): Generalize commonly used
        'tail' and 'frame' local variables.

2012-11-22  Eli Zaretskii  <eliz@gnu.org>

        * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts
        with Windows system header.

2012-11-21  Paul Eggert  <eggert@cs.ucla.edu>

        Assume POSIX 1003.1-1988 or later for unistd.h (Bug#12945).
        * alloc.c: Assume unistd.h exists.
        * fileio.c (Fexpand_file_name) [DOS_NT]: Use getcwd, not getwd.
        * sysdep.c (get_current_dir_name): Assume getcwd exists.
        (getwd) [USG]: Remove; no longer needed.
        (sys_subshell) [DOS_NT]: Use getcwd, not getwd.
        * w32.c (getcwd): Rename from getwd, and switch to getcwd's API.
        * w32.h (getcwd): Remove decl.

2012-11-21  Stefan Monnier  <monnier@iro.umontreal.ca>

        * xdisp.c (fast_set_selected_frame): Rename from update_tool_bar_unwind.
        Make it set selected_window as well.
        (update_tool_bar): Use it.

2012-11-21  Ken Brown  <kbrown@cornell.edu>

        * emacs.c (main): Set the G_SLICE environment variable for all
        Cygwin builds, not just GTK builds.  See
        https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.

2012-11-21  Eli Zaretskii  <eliz@gnu.org>

        * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
        (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
        Define for the MSVC compiler.

        * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.

        * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
        (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
        dostounix_filename.  Prevents crashes down the road, because
        dostounix_filename assumes it gets a unibyte string.
        Reported by Michel de Ruiter <michel@sentient.nl>, see

2012-11-20  Stefan Monnier  <monnier@iro.umontreal.ca>

        Conflate Qnil and Qunbound for `symbol-function'.
        * alloc.c (Fmake_symbol): Initialize `function' to Qnil.
        * lread.c (init_obarray): Set `function' fields to Qnil.
        * eval.c (Fcommandp): Ignore Qunbound.

        * data.c (Ffset, Ffboundp, indirect_function, Findirect_function):
        Test NILP rather than Qunbound.
        (Ffmakunbound): Set to Qnil.
        (Fsymbol_function): Never signal an error.
        (Finteractive_form): Ignore Qunbound.

2012-11-20  Paul Eggert  <eggert@cs.ucla.edu>

        * eval.c (interactive_p): Remove no-longer-used decl.

2012-11-20  Dmitry Antipov  <dmantipov@yandex.ru>

        * xdisp.c (buffer_shared): Adjust comment.
        (buffer_shared_and_changed): New function.
        (prepare_menu_bars, redisplay_internal): Use it to
        decide whether all windows or frames should be updated.
        (window_outdated): New function.
        (text_outside_line_unchanged_p, redisplay_window): Use it.
        (redisplay_internal): Likewise.  Fix indentation.

2012-11-20  Stefan Monnier  <monnier@iro.umontreal.ca>

        * eval.c (Finteractive_p, Fcalled_interactively_p, interactive_p): Remove.
        (syms_of_eval): Remove corresponding defsubr.

2012-11-18  Paul Eggert  <eggert@cs.ucla.edu>

        * nsterm.m (ns_select): Send SIGIO only to self, not to process group.

2012-11-18  Eli Zaretskii  <eliz@gnu.org>

        * w32select.c: Include w32common.h before w32term.h, so that
        windows.h gets included before w32term.h uses some of its
        features, see below.

        * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
        New typedefs.
        (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:
        New prototypes.

2012-11-17  Juanma Barranquero  <lekktu@gmail.com>

        * makefile.w32-in (SYSWAIT_H): New macro.
        ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
        ($(BLD)/sysdep.$(O)): Update dependencies.

2012-11-17  Paul Eggert  <eggert@cs.ucla.edu>

        Assume POSIX 1003.1-1988 or later for fcntl.h (Bug#12881).
        * callproc.c (relocate_fd): Assume F_DUPFD.
        * emacs.c, term.c (O_RDWR): Remove.
        * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
        O_NDELAY, since O_NONBLOCK is the standard name for this flag.
        * nsterm.m: Assume <fcntl.h> exists.
        * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
        (create_pty, Fmake_network_process, server_accept_connection)
        (wait_reading_process_output, init_process_emacs):
        Assume O_NONBLOCK.
        (wait_reading_process_output): Put in a special case for WINDOWSNT
        to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
        It's not clear this is needed, but it's a more-conservative change.
        (create_process): Assume FD_CLOEXEC.
        (create_process, create_pty): Assume O_NOCTTY.
        * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
        (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
        Omit if not DOS_NT, since F_GETFL is not defined there.
        (serial_open): Assume O_NONBLOCK and O_NOCTTY.
        * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
        (O_NOCTTY): Remove.
        (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
        lack it, since gnulib guarantees this.
        * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.

2012-11-17  Eli Zaretskii  <eliz@gnu.org>

        * w32.c (faccessat): Pretend that directories have the execute bit
        set.  Emacs expects that, e.g., in files.el:cd-absolute.

        * w32proc.c (create_child): Don't clip the PID of the child
        process to fit into an Emacs integer, as this is no longer a
        restriction.
        (waitpid): Rename from sys_wait.  Emulate a Posix 'waitpid' by
        reaping only the process specified by PID argument, if that is
        positive.  Use PID instead of dead_child to know which process to
        reap.  Wait for the child to die only if WNOHANG is not in
        OPTIONS.
        (sys_select): Don't set dead_child.

        * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
        as it is no longer needed.

        * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
        no longer needed.
        (record_child_status_change): Remove the setting of
        record_at_most_one_child for the !WNOHANG case.

2012-11-17  Paul Eggert  <eggert@cs.ucla.edu>

        Fix problems in ns port found by static checking.
        * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
        (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
        not to process group.
        (ns_select): Use emacs_write, not write, as that's more robust
        in the presence of signals.
        (fd_handler:): Check for read errors.

2012-11-16  Glenn Morris  <rgm@gnu.org>

        * editfns.c (Fmessage): Mention message-log-max.  (Bug#12849)

2012-11-16  Stefan Monnier  <monnier@iro.umontreal.ca>

        * eval.c (Finteractive_p): Revert lexbind-merge mishap.

2012-11-16  Eli Zaretskii  <eliz@gnu.org>

        * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
        use the same value of thread handle.
        (start_timer_thread): If the timer thread exited (due to error),
        clean up by closing the two handles it used.  Duplicate the caller
        thread's handle here, so it gets duplicated only once, when
        launching the timer thread.  Set priority of the timer thread, not
        the caller thread.
        (getitimer): Don't duplicate the caller thread's handle here.
        (Bug#12832)

2012-11-16  Jan Djärv  <jan.h.d@swipnet.se>

        * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
        called (Bug#12834).

2012-11-16  Paul Eggert  <eggert@cs.ucla.edu>

        Remove no-longer-used pty_max_bytes variable.
        * process.c (pty_max_bytes): Remove; unused.
        (send_process): Do not set it.

2012-11-15  Juanma Barranquero  <lekktu@gmail.com>

        * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
        Update dependencies.

2012-11-15  Paul Eggert  <eggert@cs.ucla.edu>

        * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
        This follows up on the 2012-09-29 patch that removed indirection
        for the 'function' field.  Reported by Sergey Vinokurov in
        <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.

2012-11-14  Eli Zaretskii  <eliz@gnu.org>

        * w32.c (faccessat): Rename from sys_faccessat.  (No need to use a
        different name, as the MS runtime does not have such a function,
        and probably never will.)  All callers changed.  Ignore DIRFD
        value if PATH is an absolute file name, to match Posix spec
        better.  If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
        symlinks.

2012-11-14  Dmitry Antipov  <dmantipov@yandex.ru>

        * xdisp.c (echo_area_display, redisplay_internal):
        Omit redundant check whether frame_garbaged is set.

2012-11-14  Paul Eggert  <eggert@cs.ucla.edu>

        Use faccessat, not access, when checking file permissions (Bug#12632).
        This fixes a bug that has been present in Emacs since its creation.
        It was reported by Chris Torek in 1983 even before GNU Emacs existed,
        which must set some sort of record.  (Torek's bug report was against
        a predecessor of GNU Emacs, but GNU Emacs happened to have the
        same common flaw.)  See Torek's Usenet posting
        "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
        Posted: Fri Apr  8 14:18:56 1983.
        * Makefile.in (LIB_EACCESS): New macro.
        (LIBES): Use it.
        * callproc.c (init_callproc):
        * charset.c (init_charset):
        * fileio.c (check_existing, check_executable, check_writable)
        (Ffile_readable_p):
        * lread.c (openp, load_path_check):
        * process.c (allocate_pty):
        * xrdb.c (file_p):
        Use effective UID when checking permissions, not real UID.
        * callproc.c (init_callproc):
        * charset.c (init_charset):
        * lread.c (load_path_check, init_lread):
        Test whether directories are accessible, not merely whether they exist.
        * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
        * fileio.c (check_existing, check_executable, check_writable)
        (Ffile_readable_p):
        Use symbolic names instead of integers for the flags, as they're
        portable now.
        (check_writable): New arg AMODE.  All uses changed.
        Set errno on failure.
        (Ffile_readable_p): Use faccessat, not stat + open + close.
        (Ffile_writable_p): No need to call check_existing + check_writable.
        Just call check_writable and then look at errno.  This saves a syscall.
        dir should never be nil; replace an unnecessary runtime check
        with an eassert.  When checking the parent directory of a nonexistent
        file, check that the directory is searchable as well as writable, as
        we can't create files in unsearchable directories.
        (file_directory_p): New function, which uses 'stat' on most platforms
        but faccessat with D_OK (for efficiency) if WINDOWSNT.
        (Ffile_directory_p, Fset_file_times): Use it.
        (file_accessible_directory_p): New function, which uses a single
        syscall for efficiency.
        (Ffile_accessible_directory_p): Use it.
        * xrdb.c (file_p): Use file_directory_p.
        * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
        * lread.c (openp): When opening a file, use fstat rather than
        stat, as that avoids a permissions race.  When not opening a file,
        use file_directory_p rather than stat.
        (dir_warning): First arg is now a usage string, not a format.
        Use errno.  All uses changed.
        * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
        that merely introduced a race.
        * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
        changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
        and similarly for the other O_* flags.
        * w32.c (sys_faccessat): Rename from sys_access and switch to
        faccessat's API.  All uses changed.
        * xrdb.c: Do not include <sys/stat.h>; no longer needed.
        (magic_db): Rename from magic_file_p.
        (magic_db, search_magic_path): Return an XrmDatabase rather than a
        char *, so that we don't have to test for file existence
        separately from opening the file for reading.  This removes a race
        fixes a permission-checking problem, and simplifies the code.
        All uses changed.
        (file_p): Remove; no longer needed.

2012-11-13  Dmitry Antipov  <dmantipov@yandex.ru>

        Omit glyphs initialization at startup.
        * dispnew.c (glyphs_initialized_initially_p): Remove.
        (adjust_frame_glyphs_initially): Likewise.  Adjust users.
        (Fredraw_frame): Move actual code from here...
        (redraw_frame): ...to here.  Add eassert.  Adjust comment.
        (Fredraw_display): Use redraw_frame.
        * xdisp.c (clear_garbaged_frames): Likewise.

2012-11-13  Eli Zaretskii  <eliz@gnu.org>

        * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
        passed to pint2str and pint2hrstr to be at most the size of the
        frame's decode_mode_spec_buffer.  This avoids crashes with very
        large values of FIELD_WIDTH argument to decode_mode_spec.
        (Bug#12867)

2012-11-13  Paul Eggert  <eggert@cs.ucla.edu>

        Fix a race with verify-visited-file-modtime (Bug#12863).
        Since at least 1991 Emacs has ignored an mtime difference of no
        more than one second, but my guess is that this was to work around
        file system bugs that were fixed long ago.  Since the race is
        causing problems now, let's remove that code.
        * fileio.c (Fverify_visited_file_modtime): Do not accept a file
        whose time stamp is off by no more than a second.  Insist that the
        file time stamps match exactly.

2012-11-12  Dmitry Antipov  <dmantipov@yandex.ru>

        * frame.h (struct frame): Convert external_tool_bar member to
        1-bit unsigned bitfield.
        * termhooks.h (struct terminal): Remove mouse_moved member since
        all users are long dead.  Adjust comment on mouse_position_hook.

2012-11-12  Dmitry Antipov  <dmantipov@yandex.ru>

        Simplify by using FOR_EACH_FRAME here and there.
        * frame.c (next_frame, prev_frame, other_visible_frames)
        (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
        * w32term.c (x_window_to_scroll_bar): Likewise.
        * window.c (window_list): Likewise.
        * xdisp.c (x_consider_frame_title): Likewise.
        * xfaces.c ( Fdisplay_supports_face_attributes_p): Likewise.
        * xfns.c (x_window_to_frame, x_any_window_to_frame)
        (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
        * xmenu.c (menubar_id_to_frame): Likewise.
        * xselect.c (frame_for_x_selection): Likewise.
        * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
        (x_window_to_menu_bar): Likewise.
        * w32fns.c (x_window_to_frame): Likewise.  Adjust comment.

2012-11-12  Paul Eggert  <eggert@cs.ucla.edu>

        * data.c (Qdefalias_fset_function): Now static.

        Another tweak to vectorlike_header change.
        * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
        Remove, and replace all uses with ...
        (next_in_free_list, set_next_in_free_list):
        New functions, which respect C's aliasing rules better.

2012-11-11  Paul Eggert  <eggert@cs.ucla.edu>

        * window.c (list4i): Rename from 'quad'.  All uses changed.
        Needed because <sys/types.h> defines 'quad' on Solaris 10.

2012-11-11  Juanma Barranquero  <lekktu@gmail.com>

        * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
        warning about mixing declarations and code in ISO C90.

2012-11-10  Martin Rudalics  <rudalics@gmx.at>

        * window.c (Fsplit_window_internal): Set combination limit of
        new parent window to t iff Vwindow_combination_limit is t;
        fixing a regression introduced with the change from 2012-09-22.
        (Fset_window_combination_limit): Fix doc-string.

2012-11-10  Eli Zaretskii  <eliz@gnu.org>

        * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
        amount when the scroll margins are too large.  When scrolling
        backwards in the buffer, give up if cannot reach point or the
        scroll margin within a reasonable number of screen lines.
        Fixes point position in window under scroll-up/down-aggressively when
        point is positioned many lines beyond the window top/bottom.
        (Bug#12811)

        * ralloc.c (relinquish): If real_morecore fails to return memory
        to the system, don't crash; instead, leave the last heap
        unchanged and return.  (Bug#12774)

2012-11-09  Stefan Monnier  <monnier@iro.umontreal.ca>

        (SCROLL_BAR_VEC_SIZE): Remove.
        * w32term.c (x_scroll_bar_create): Use VECSIZE.

2012-11-09  Dmitry Antipov  <dmantipov@yandex.ru>

        Tweak last vectorlike_header change.
        * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
        vectorlike object on the free list.  This is introduced to avoid
        some (but not all) pointer casting and aliasing problems, see
        http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
        * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike
        objects.
        (xvectype, xvecsize): Use them to examine Lisp_Object values.

2012-11-09  Jan Djärv  <jan.h.d@swipnet.se>

        * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
        been removed, so remove them here also.

2012-11-09  Stefan Monnier  <monnier@iro.umontreal.ca>

        * doc.c (Fdocumentation): Handle new property
        dynamic-docstring-function to replace the old ad-advice-info.

2012-11-09  Paul Eggert  <eggert@cs.ucla.edu>

        * fns.c (Qeql, hashtest_eq): Now static.

        * buffer.c (compare_overlays): Use XLI rather than XHASH.

2012-11-08  Paul Eggert  <eggert@cs.ucla.edu>

        Use same hash function for hashfn_profiler as for hash_string etc.
        * fns.c (SXHASH_COMBINE): Remove.  All uses replaced by sxhash_combine.
        * lisp.h (sxhash_combine): New inline function, with the contents
        of the old SXHASH_COMBINE.
        * profiler.c (hashfn_profiler): Use it, instead of having a
        special hash function containing a comparison that always yields 1.

2012-11-08  Stefan Monnier  <monnier@iro.umontreal.ca>

        * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)

        make_hash_table changed.

2012-11-08  Thomas Kappler  <tkappler@gmail.com>  (tiny change)

        * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).

2012-11-08  Stefan Monnier  <monnier@iro.umontreal.ca>

        Use ad-hoc comparison function for the profiler's hash-tables.
        * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.

        (cmpfn_profiler, hashfn_profiler): New functions.
        (syms_of_profiler): Initialize them.

        * w32fns.c (modifier_set): Fix handling of Scroll Lock when the
        value of w32-scroll-lock-modifier is neither nil nor one of the
        known key modifiers.  (Bug#12806)

2012-11-08  Dmitry Antipov  <dmantipov@yandex.ru>

        Shrink struct vectorlike_header to the only size field.
        * lisp.h (enum pvec_type): Avoid explicit enum member values.
        Adjust comment.
        (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and
        PVEC_TYPE_MASK to arrange new bitfield in the vector header.
        (PSEUDOVECTOR_REST_BITS, PSEUDOVECTOR_REST_MASK): New members.
        (PSEUDOVECTOR_AREA_BITS): New member used to extract subtype

        layout.
        (XSETSUBR, SUBRP): Adjust to match new Lisp_Subr layout.
        (struct vectorlike_header): Remove next member.  Adjust comment.

        (struct large_vector): New type to represent allocation unit for
        the vectors with the memory footprint more than VBLOOCK_BYTES_MAX.
        (large_vectors): Change type to struct large_vector.
        (allocate_vector_from_block): Simplify.

        New macros.

        * fns.c (internal_equal): Adjust to match enum pvec_type change.
        (copy_hash_table): Adjust to match vector header change.
        * lread.c (defsubr): Use XSETPVECTYPE.
        * .gdbinit (xpr, xbacktrace): Adjust to match vector header change.
        (xvectype): Likewise.  Print PVEC_NORMAL_VECTOR for regular vectors.
        (xvecsize): New command.

2012-11-08  Dmitry Antipov  <dmantipov@yandex.ru>

        * keyboard.c (event_to_kboard): Do not dereference
        frame_or_window field of SELECTION_REQUEST_EVENT
        and SELECTION_CLEAR_EVENT events (Bug#12814).
        * xterm.h (struct selection_input_event): Adjust comment.

2012-11-07  Eli Zaretskii  <eliz@gnu.org>

        * w32fns.c (modifier_set): Don't report modifiers from toggle key,
        such as Scroll Lock, if the respective keys are treated as
        function keys, not as modifiers.  This avoids destroying non-ASCII
        keyboard input when Scroll Lock is toggled ON.  (Bug#12806)

2012-11-07  Dmitry Antipov  <dmantipov@yandex.ru>

        * xfns.c (Fx_wm_set_size_hint): Use check_x_frame.  Adjust docstring.

2012-11-06  Paul Eggert  <eggert@cs.ucla.edu>

        Restore some duplicate definitions (Bug#12814).
        This undoes part of the 2012-11-03 changes.  Some people build
        with plain -g rather than with -g3, and they need the duplicate
        definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
        * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
        Define as macros, as well as as enums or as constants.

2012-11-06  Jan Djärv  <jan.h.d@swipnet.se>

        * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
        to keypad keys (Bug#12816).

2012-11-06  Paul Eggert  <eggert@cs.ucla.edu>

        Minor adjustments of recently-changed frame functions.
        * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
        known to be a frame (we're in the FRAMEP branch).
        * lisp.h (Qframep): Remove decl.  frame.h declares this.
        * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
        since they're meant for Lisp fixnum values.

2012-11-06  Dmitry Antipov  <dmantipov@yandex.ru>

        * window.c (Fwindow_combination_limit): Revert to the only
        required argument and adjust docstring as suggested in
        http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
        by Martin Rudalics <rudalics@gmx.at>.

2012-11-06  Dmitry Antipov  <dmantipov@yandex.ru>

        Widely used frame validity and checking functions.
        * frame.h (decode_live_frame, decode_any_frame): Add prototypes.
        * frame.c (decode_live_frame, decode_any_frame): New functions.
        (delete_frame, Fredirect_frame_focus, Fframe_parameters)

        (Fset_frame_height, Fset_frame_width): Use decode_live_frame.
        (Fframe_focus): Likewise.  Allow zero number of arguments.
        Adjust docstring.
        (frame_buffer_list, frame_buffer_predicate): Remove.
        * lisp.h (frame_buffer_predicate): Remove prototype.
        * buffer.c (Fother_buffer): Use decode_any_frame.
        * xdisp.c (Ftool_bar_lines_needed): Likewise.

        (Fcurrent_window_configuration): Likewise.
        (Frun_window_configuration_change_hook, Fwindow_resize_apply):
        Likewise.  Allow zero number of arguments.  Adjust docstring.
        * dispnew.c (Fredraw_frame): Likewise.
        * xfaces.c (frame_or_selected_frame): Remove.
        (Fx_list_fonts, Finternal_get_lisp_face_attribute, Fface_font)
        (Finternal_lisp_face_equal_p, Finternal_lisp_face_empty_p)
        (Fframe_face_alist): Use decode_live_frame.
        * xfns.c (check_x_frame): Likewise.

2012-11-06  Dmitry Antipov  <dmantipov@yandex.ru>

        * window.c (quad): New function.
        (Fwindow_edges, Fwindow_pixel_edges, Fwindow_inside_edges)
        (Fwindow_absolute_pixel_edges, Fwindow_inside_absolute_pixel_edges)
        (Fwindow_inside_pixel_edges, Fpos_visible_in_window_p)
        (Fwindow_line_height): Use it.
        (Fwindow_fringes): Use list3.
        (Fwindow_scroll_bars): Use list4.
        (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
        (Fwindow_combination_limit): Allow zero number of arguments.

2012-11-05  Eli Zaretskii  <eliz@gnu.org>

        * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.

        * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
        (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
        file descriptor 2 for standard error.  (Bug#12805)

2012-11-05  Chong Yidong  <cyd@gnu.org>

        * process.c (wait_reading_process_output): Revert previous change.

2012-11-05  Paul Eggert  <eggert@cs.ucla.edu>

        Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
        This removes code that has been obsolete since around 1990.
        * callproc.c (Fcall_process):
        * emacs.c (main):
        * process.c (create_process):
        * term.c (dissociate_if_controlling_tty):
        Assume setsid exists.
        * callproc.c (child_setup): Assume setpgid exists and behaves as
        per POSIX.1-1988 or later.
        * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
        * emacs.c (shut_down_emacs):
        * sysdep.c (sys_suspend, init_foreground_group):
        Assume getpgrp behaves as per POSIX.1-1998 or later.
        * msdos.c (setpgrp): Remove.
        (tcgetpgrp, setpgid, setsid): New functions.
        * systty.h (EMACS_GETPGRP): Remove.  All callers now use getpgrp.
        * term.c (no_controlling_tty): Remove; unused.
        * w32proc.c (setpgrp): Remove.
        (setsid, tcgetpgrp): New functions.

        Simplify by assuming __fpending.
        * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
        (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
        Do not assume that __fpending's result fits in int.

2012-11-04  Paul Eggert  <eggert@cs.ucla.edu>

        Remove EMACS_OUTQSIZE+sleep hack.
        * dispnew.c (update_frame_1): Remove hack for terminals slower
        than 2400 bps, which throttled Emacs by having it sleep.
        This code hasn't worked since at least 2007, when the multi-tty stuff
        was added, and anyway those old terminals are long dead.
        * systty.h (EMACS_OUTQSIZE): Remove; unused.  The macro isn't used even
        without the dispnew.c change, as dispnew.c doesn't include systty.h.

        Fix data-loss with --version (Bug#9574).
        * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
        as we can't assume that emacs_strerror is initialized, and strerror
        is good enough here.
        (main): Invoke atexit earlier, to catch earlier instances of
        sending data to stdout and exiting, e.g., "emacs --version >/dev/full".

2012-11-04  Michael Marchionna  <tralfaz@pacbell.net>

        * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
        (keyDown): Remap keypad keys to X11 virtual key codes.

2012-11-03  Paul Eggert  <eggert@cs.ucla.edu>

        Fix data-loss with --batch (Bug#9574).
        * emacs.c: Include <close-stream.h>.
        (close_output_streams): New function.
        (main): Pass it to atexit, so that Emacs closes stdout and stderr
        and handles errors appropriately.
        (Fkill_emacs): Don't worry about flushing, as close_output_stream
        does that now.

        Fix a race condition that causes Emacs to mess up glib (Bug#8855).
        The symptom is a diagnostic "GLib-WARNING **: In call to
        g_spawn_sync(), exit status of a child process was requested but
        SIGCHLD action was set to SIG_IGN and ECHILD was received by
        waitpid(), so exit status can't be returned."  The diagnostic
        is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
        The real bug is a race condition between Emacs and glib: Emacs
        does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
        so that glib can't find it.  Work around the bug by invoking
        waitpid only on subprocesses that Emacs itself creates.
        * process.c (create_process, record_child_status_change):
        Don't use special value -1 in pid field, as the caller now must
        know the pid rather than having the callee infer it.
        The inference was sometimes incorrect anyway, due to another race.
        (create_process): Set new 'alive' member if child is created.
        (process_status_retrieved): New function.
        (record_child_status_change): Use it.
        Accept negative 1st argument, which means to wait for the
        processes that Emacs already knows about.  Move special-case code
        for DOS_NT (which lacks WNOHANG) here, from caller.  Keep track of
        processes that have already been waited for, by testing and
        clearing new 'alive' member.
        (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
        now does this internally.
        (handle_child_signal): Let record_child_status_change do all
        the work, since we do not want to reap all exited child processes,
        only the child processes that Emacs itself created.
        * process.h (Lisp_Process): New boolean member 'alive'.

        Omit duplicate definitions no longer needed with gcc -g3.
        * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
        (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
        Define only as macros.  There's no longer any need to also define
        these symbols as enums or as constants, since we now assume
        gcc -g3 when debugging.

2012-11-03  Eli Zaretskii  <eliz@gnu.org>

        * lisp.mk: Adjust comments to the fact that term/internal is now
        loaded from loadup.el.

        * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
        (msdos_fatal_signal): New function.
        (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
        its argument list.

        * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
        for GCC versions before 4.
        (emacs_raise): Define to call msdos_fatal_signal.

        * xdisp.c (init_from_display_pos): Fix initialization of the bidi
        iterator when starting in the middle of a display or overlay
        string.  (Bug#12745)

2012-11-03  Chong Yidong  <cyd@gnu.org>

        * process.c (wait_reading_process_output): Clean up the last
        change.

2012-11-03  Jim Paris  <jim@jtan.com>  (tiny change)

        * process.c (wait_reading_process_output): Avoid a race condition
        with SIGIO delivery (Bug#11536).

2012-11-03  Chong Yidong  <cyd@gnu.org>

        * buffer.c (cursor_type): Untabify docstring.

2012-11-03  Dmitry Antipov  <dmantipov@yandex.ru>

        * frame.h (struct frame): Drop can_have_scroll_bars member
        which is meaningless for a long time.  Adjust comments.
        (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
        * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.

2012-11-03  Dmitry Antipov  <dmantipov@yandex.ru>

        * window.c (decode_next_window_args): Update window arg after
        calling decode_live_window and so fix crash reported at
        http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
        by Juanma Barranquero <lekktu@gmail.com>.

2012-11-02  Dmitry Antipov  <dmantipov@yandex.ru>

        Window-related stuff cleanup here and there.
        * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
        Use decode_any_window.
        * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
        * xdisp.c (Fformat_mode_line): Likewise.
        * font.c (Ffont_at): Use decode_live_window.

        respectively.

2012-11-02  Dmitry Antipov  <dmantipov@yandex.ru>

        Remove pad from struct input_event.
        * termhooks.h (struct input_event): Remove padding field.
        Adjust comment.
        * keyboard.c (event_to_kboard): Simplify because frame_or_window
        member is never cons for a long time.  Adjust comment.
        (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
        SELECTION_CLEAR_EVENT has no Lisp_Objects to mark.  Add comment.
        * xterm.c (handle_one_xevent): Do not initialize frame_or_window
        field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.

2012-11-01  Eli Zaretskii  <eliz@gnu.org>

        * w32proc.c (getpgrp, setpgid): New functions.  (Bug#12776)

2012-10-31  Paul Eggert  <eggert@cs.ucla.edu>

        Fix crash when using Emacs as commit editor for git (Bug#12697).
        * callproc.c (setpgrp): Remove macro, as we now use setpgid
        and it is configured in conf_post.h.
        (Fcall_process): Don't invoke both setsid and setpgid; the former
        is enough, if it exists.
        * callproc.c (Fcall_process, child_setup):
        * process.c (create_process): Use setpgid.
        * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
        for the real thing.
        * dispnew.c (init_display): Initialize the foreground group
        if we are running a tty display.
        * emacs.c (main): Do not worry about setpgrp; init_display does it now.

        * sysdep.c (inherited_pgroup): New static var.
        (init_foreground_group, tcsetpgrp_without_stopping)

        (init_sys_modes): Narrow foreground group.
        (reset_sys_modes): Widen foreground group.

2012-10-31  Michael Albinus  <michael.albinus@gmx.de>

        * dbusbind.c: Fix cut'n'waste error.  Use HAVE_DBUS_VALIDATE_INTERFACE.

2012-10-31  Martin Rudalics  <rudalics@gmx.at>

        * minibuf.c (read_minibuf): Restore current buffer since
        choose_minibuf_frame calling Fset_frame_selected_window may
        change it (Bug#12766).

2012-10-30  Jan Djärv  <jan.h.d@swipnet.se>

        * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).

2012-10-30  Kenichi Handa  <handa@gnu.org>

        * font.c (Ffont_at): If WINDOW is specified and it is not
        displaying the current buffer, signal an error.

2012-10-29  Daniel Colascione  <dancol@dancol.org>

        * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
        In preparation for fixing bug#12739, move these functions from
        here...

        * coding.h, coding.c: ... to here, and compile them only when
        WINDOWSNT or CYGWIN.  Moving these functions out of cygw32 proper
        lets us write cygw32-agnostic code for the HAVE_NTGUI case.

2012-10-28  Eli Zaretskii  <eliz@gnu.org>

        * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
        (timer_loop, getitimer, setitimer): Use it instead of
        CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
        'clock'.
        (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
        literal 10000.

2012-10-28  Jan Djärv  <jan.h.d@swipnet.se>

        * nsterm.m (NO_APPDEFINED_DATA): New define.

        (last_appdefined_event): Remove.
        (ns_select): Initialize t from last_appdefined_event_data instead
        of [last_appdefined_event data1].
        (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
        remove last_appdefined_event (Bug#12698).

2012-10-28  Stefan Monnier  <monnier@iro.umontreal.ca>

        * frame.c (x_set_font): Catch internal error.

2012-10-27  Eli Zaretskii  <eliz@gnu.org>

        Avoid overflow in w32 implementation of interval timers.
        When possible, for ITIMER_PROF count only times the main thread
        actually executes.
        * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
        'volatile ULONGLONG' types.  All the other data which was
        previously clock_t is now ULONGLONG.  'terminate' is 'volatile int'.
        (GetThreadTimes_Proc): New typedef.
        (w32_get_timer_time): New function, returns a suitable time value
        for the timer.
        (timer_loop): Enter critical section when accessing ULONGLONG
        values of the itimer_data struct, as these accesses are no longer
        atomic.  Call 'w32_get_timer_time' instead of 'clock'.
        Remove unused variable.
        (init_timers): Initialize s_pfn_Get_Thread_Times.
        (start_timer_thread): Don't assign itimer->caller_thread here.
        (getitimer): Assign itimer->caller_thread here.
        (setitimer): Always call getitimer to get the value of ticks_now.
        (sys_spawnve): Avoid compiler warning about format mismatch.

2012-10-26  Eli Zaretskii  <eliz@gnu.org>

        * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
        mouse movement events if the menu bar is active.  This avoids
        producing a busy "hour-glass" cursor by Windows if the mouse
        pointer is positioned over a tooltip shown for some menu item.

2012-10-25  Paul Eggert  <eggert@cs.ucla.edu>

        Don't assume process IDs fit in int.
        * emacs.c (shut_down_emacs) [!DOS_NT]:
        * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
        * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
        Use pid_t, not int, to store process IDs, as 'int'
        is not wide enough on a few platforms (e.g., AIX and IRIX).

2012-10-23  Kenichi Handa  <handa@gnu.org>

        The following change is to make face-font-rescale-alist work
        correctly for non-ASCII fonts.

        * font.c (font_open_entity): Don't handle Vface_font_rescale_alist.
        (font_open_for_lface): Handle Vface_font_rescale_alist.

2012-10-23  Chong Yidong  <cyd@gnu.org>

        * xfaces.c (Vfont_list_limit): Move unused variable to faces.el.

        for screen font.
        (nsfont_draw): Turn off LCD-smoothing (Bug#11484).

        * xterm.c (x_focus_changed): Check if daemonp when sending focus in
        event (Bug#12681).

2012-10-21  Glenn Morris  <rgm@gnu.org>

        * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.

2012-10-20  Paul Eggert  <eggert@cs.ucla.edu>

        Port to OpenBSD 5.1.
        * frame.c (Fmouse_position, Fmouse_pixel_position):
        * xdisp.c (produce_stretch_glyph):
        Declare local vars only when they're needed.
        This is clearer and avoids a warning on OpenBSD about unused vars.
        * frame.h (FRAME_WINDOW_P): Always evaluate its argument.
        This is safer, and avoids OpenBSD warnings about unused vars.
        * keyboard.c (record_menu_key): Remove unnecessary decl.
        (poll_timer): Define only if POLL_FOR_INPUT is defined.
        * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
        as our definition clashes with OpenBSD's.
        * xfaces.c (load_face_colors, check_lface_attrs)
        (get_lface_attributes_no_remap, get_lface_attributes)
        (lface_fully_specified_p, x_supports_face_attributes_p)
        (tty_supports_face_attributes_p, face_fontset, realize_face)
        (realize_x_face, realize_tty_face):
        Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
        merely Lisp_Object *.  This is more informative and avoids
        a warning on OpenBSD about accessing beyond an object's size.

2012-10-20  Chong Yidong  <cyd@gnu.org>

        * lread.c (Fload): Doc fix (Bug#12592).

        FD_ISSET (Bug#12668).

2012-10-18  Daniel Colascione  <dancol@dancol.org>

        * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
        (staticpro): If we run out of staticpro slots, die with an
        informative error instead of just calling emacs_abort.

2012-10-18  Martin Rudalics  <rudalics@gmx.at>

        Fix two flaws reported by Dmitry Antipov.
        * window.c (Ftemp_output_buffer_show): Remove.

        * image.c (init_tiff_functions, init_imagemagick_functions)
        (init_svg_functions): Fix cygw32 build break by using these
        functions only when WINDOWSNT _and_ HAVE_NTGUI.

2012-10-14  Jan Djärv  <jan.h.d@swipnet.se>

        * nsterm.m (ns_select): Count fd:s in writefs also (Bug#12422).

        instead of calling 'stat', when what's needed is to check whether

        (Bug#12587)

        * w32.c (init_environment): Call 'check_existing' instead of 'stat'.

        * lread.c (openp) [WINDOWSNT]: Call 'access' instead of 'stat' to

        Use bool for booleans.
        * lread.c (safe_to_load_version): Rename from safe_to_load_p,
        as it's not a predicate.  All uses changed.  Omit unnecessary
        buffer termination.

2012-10-11  Dmitry Antipov  <dmantipov@yandex.ru>

        * editfns.c (save_excursion_save): Use nil if mark points to nowhere.

        * marker.c (cached_modiff): EMACS_INT, not int.

        * w32select.c (waiting_for_input): Declare by including "keyboard.h"
        instead of having a wrong decl.
        * nsmenu.m (waiting_for_input): Remove wrong decl.

        Use unsigned for counter where wraparound-on-overflow is desired,
        since unsigned is guaranteed to have that behavior and signed is not.
        (read_char): Use ptrdiff_t for string length.
        (get_input_pending): Remove first argument, since it was always
        the same pointer-to-int (now pointer-to-boolean) &input_pending,
        and behave as if it had that value.  Return new value of
        input_pending.  All callers changed.
        * keyboard.h (struct kboard): Use unsigned : 1 for boolean member
        immediate_echo.  Use ptrdiff_t for echo_after_prompt, since it's
        a string length.
        * keymap.c (push_key_description): Omit last arg, which was always 1.
        All callers changed.

        * regex.c (immediate_quit) [emacs]: Remove duplicate decl.

        initializer for PVEC_NORMAL_VECTOR.

2012-10-10  Paul Eggert  <eggert@cs.ucla.edu>

        Clean out old termopts cruft.

        Don't include termopts.h.

2012-10-10  Dmitry Antipov  <dmantipov@yandex.ru>

        * w32fns.c (w32_last_error): Change the return value to DWORD, to
        match what GetLastError returns.  Explain why the function is
        needed.

        * frame.c (delete_frame): Rename local variable 'tooltip_frame' to
        'is_tooltip_frame', to avoid confusion with its global namesake.

2012-10-08  Daniel Colascione  <dancol@dancol.org>

        * xdisp.c (start_hourglass): Call w32_note_current_window when
        HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
        build that caused Emacs to display the hourglass cursor forever.

        * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
        which is broken under remote desktop, calculate the number of
        colors available for a display based on the display's number of
        planes and number of bits per pixel per plane.  (bug#10397).

2012-10-08  Jan Djärv  <jan.h.d@swipnet.se>

        * nsfont.m (Vfonts_in_cache): New variable.
        (nsfont_open): Use unsignedLongLongValue for cache in case wide ints
        are used.  Add cached fonts to Vfonts_in_cache.
        (syms_of_nsfont): Initialize and staticpro Vfonts_in_cache.

2012-10-08  Juanma Barranquero  <lekktu@gmail.com>

        * makefile.w32-in (LOCAL_FLAGS): Don't define HAVE_NTGUI, it's now
        in nt/config.nt.
        (FONT_H): Define after FRAME_H.
        ($(BLD)/emacs.$(O), $(BLD)/process.$(O), $(BLD)/w32heap.$(O)):

2012-10-08  Eli Zaretskii  <eliz@gnu.org>

        * makefile.w32-in (FONT_H): Add $(FRAME_H).
        (W32TERM_H): Add $(ATIMER_H) and $(FRAME_H).
        ($(BLD)/emacs.$(O), $(BLD)/w32console.$(O)): Update dependencies.
        (GLOBAL_SOURCES): Add cygw32.c.

        * w32fns.c (w32_color_map_lookup, x_to_w32_color): Argument is now
        'const char *'.
        (x_to_w32_color): Don't modify the argument, modify a copy instead.

2012-10-08  Daniel Colascione  <dancol@dancol.org>

        * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
        (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
        accidental message numbering hole.  Change other messages to
        match.

        * w32select.h (HAVE_W32SELECT): Remove.

        * w32select.c, w32proc.c, w32menu.c, w32console.c, w32.c: Include
        w32common.h instead of w32heap.h.

        * w32heap.h (ROUND_UP, ROUND_DOWN, get_page_size)
        (get_allocation_unit, get_processor_type, get_w32_major_version)
        (get_w32_minor_version, sysinfo_cache, osinfo_cache)
        (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
        (OS_NT, os_subtype, cache_system_info): Move declarations to
        w32common.

        (sysinfo_cache, syspage_mask, osinfo_cache, w32_major_version)
        (w32_minor_version, w32_build_number, w32_subtype):
        Remove duplicate definitions.

        * w32fns.c: Include w32common.h; include w32heap.h only in
        WINDOWSNT.

        (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
        Use `report_file_error' instead of `error' in order to better
        inform users of what went wrong.  Increase NTGUI_UNICODE file
        dialog box file name length to 32k, the maximum allowed by the NT
        kernel.

        * w32common.h: New file.
        (ROUND_UP, ROUND_DOWN, get_page_size)
        (get_allocation_unit, get_processor_type, get_w32_major_version)
        (get_w32_minor_version, sysinfo_cache, osinfo_cache)
        (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
        (OS_NT, os_subtype, cache_system_info): Move here.

        * unexw32.c, unexcw.c: Include w32common.h.

        * emacs.c (main): Use (defined (WINDOWSNT) || defined
        HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
        to call syms_of_w32select.

        * cygw32.h: Remove obsolete EXFUN declarations.

        * cygw32.c (Qutf_16_le): Rename to Qutf_16le.

        * Makefile.in (SOME_MACHINE_OBJECTS): Reverse accidental removal
        of w32inevt.o from SOME_MACHINE_OBJECTS.

2012-10-08  Daniel Colascione  <dancol@dancol.org>

        * image.c: Permanent fix for JPEG compilation issue --- limit
        jpeglib `boolean' redefinition to Cygwin builds.

2012-10-08  Eli Zaretskii  <eliz@gnu.org>

        * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.

        * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
        Cygwin.

2012-10-08  Daniel Colascione  <dancol@dancol.org>

        * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
        w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
        w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
        w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
        keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
        emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
        Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
        operating system.  defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
        now a supported configuration.

        * Makefile.in: consolidate image variables into LIBIMAGE; add
        W32_OBJ and W32_LIBS.  Compile new files.

        * conf_post.h:
        (_DebPrint) declare tracing facility for W32 debugging.  We need
        to unify tracing later.

        (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
        unconditional use of W32 Unicode functions.  Cygwin runs only on
        100% Unicode operating systems.

        * cygw32.c: New file.  Define Cygwin-specific facilities.
        (Fcygwin_convert_path_to_windows)
        (Fcygwin_convert_path_from_windows): New user functions for
        accessing Cygwin path-munging routines.

        * cygw32.h: New file.
        (WCSDATA, to_unicode, from_unicode): Define facilities for storing
        UTF-16LE strings temporarily inside non-Lisp-visible string
        objects.

        (w32_strerror): Just what it says on the tin.

        * emacs.c: Make the NS fork-then-exec code for daemon-launching
        also run for Cygwin; both systems have the same problem with using
        GUI facilities in a forked child.  Also call syms_of_cygw32,
        syms_of_w32select in correct places.

        (DAEMON_MUST_EXEC): new macro defined to signal that a platform
        needs fork-then-exec for daemon launching.

        * font.h: Include frame.h.

        * image.c: Use the image library cache machinery only when we're
        compiling for native WINDOWSNT; Cygwin can use shared libraries
        like any other Unixlike system.

        * keyboard.c: Clarify a comment regarding the input loop.

        * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
        functions directly instead of trying to detect at runtime that our
        host operating system supports them.  We make this change for two
        reasons: Cygwin lacks support for the multibyte character
        conversion functions used by the legacy menu code, and Cygwin
        never needs to rely on non-Unicode APIs.

        * unexw32.c (hinst): Declare extern.

        * w32.c: Change header order;
        (w32_strerror): Move to w32fns.c because we need it for
        non-WINDOWSNT builds.

        * w32.h: Add #error macro to make sure we don't include w32.h for
        Cygwin builds.  Remove w32select declarations.

        * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
        w32fns.c.  w32console.c is WINDOWSNT-only.

        * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
        NTGUI_UNICODE tweaks.  (See above.) Change _snprintf to the more
        POSIXy alternative.
        (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
        (w32_major_version, w32_minor_version, w32_build_number)
        (os_subtype, sound_type): Define here
        (w32_defined_color): Make color parameter const for consistency
        with other _defined_color functions.
        (w32_createwindow): Unconditionally call w32_init_class instead of
        doing so only when hprevinst is non-NULL.  Plumbing hprevinst
        through the code is complex and unnecessary because class
        registration is practically free.
        (w32_name_of_message): New EMACSDEBUG-only function.
        (Fset_message_beep): Move here
        (Fx_open_connection): Require that the display name for Windows be
        "w32" for consistency, emacsclient disambiguation, and maybe, one
        day, multi-window-system support.
        (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
        Cygwin files for W32 GUI facilities, since these clearly don't
        expect Cygwin names.
        (_DebPrint): Define.
        (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
        (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
        (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
        (w32_last_error): Remove.

        * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.

        * w32heap.c (syspage_mask): Declare here.
        (cache_system_info): Remove.

        * w32inevt.c (faked_key): Define globally, not statically.
        (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
        (w32_console_toggle_lock_key): Move to w32fns.c.

        * w32menu.c: Include setjmp.h.  NTGUI_UNICODE changes throughout.

        * w32proc.c (_DebPrint): Move to w32fns.c.
        * w32select.c: Include string.h, stdio.h for Cygwin.
        * w32select.h: New File.

        * w32term.c: Include io.h for non-CYGWIN builds; needed for
        get_osfhandle.
        (w32_message_fd): New variable.  Under Cygwin, holds the file
        descriptor the system used to tell us about pending thread
        messages.

        (w32_init_term): Remove incorrect calls to fcntl and init_sigio
        that prevented compilation under non-WINDOWSNT systems.

        (w32_initialize): Open /dev/windows and assign it to
        w32_message_fd.  Provide w32 feature.

        * w32term.h: Include frame.h, atimer.h.  Declare various frame functions.
        (WM_EMACS_INPUT_READY): add.
        (prepend_msg, w32_message_fd): Declare globally.

        * w32xfns.c:
        (keyboard_handle): Use only when WINDOWSNT.
        (notify_msg_ready): New function.  Posts a message to the main
        thread's message queue under CYGWIN, which wakes up the main
        thread from select(2) by making the /dev/windows file descriptor
        ready.  Under WINDOWSNT, it sets an event the same way the old
        code did.

        (post, prepend_msg): Actually call notify_msg_ready instead of
        setting the input event directly.

2012-10-07  Eli Zaretskii  <eliz@gnu.org>

        * ralloc.c (relinquish): If a heap is ready to be relinquished,
        but it still has blocs in it, don't return it to the system,
        instead of aborting.  (Bug#12402)

2012-10-07  Jan Djärv  <jan.h.d@swipnet.se>

        * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).

        * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
        MAC_OS_X_VERSION_10_6.
        (syms_of_nsterm): Remove comment about Panther and above for
        ns-antialias-text.
        * nsterm.h (MAC_OS_X_VERSION_10_3, onTiger): Remove.
        (EmacsApp): Remove check for >= MAC_OS_X_VERSION_10_4.
        (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.

        * nsselect.m (ns_string_from_pasteboard): Remove check for >=
        MAC_OS_X_VERSION_10_4.

        * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
        (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.

        * nsterm.m (ns_in_resize): Remove (Bug#12479).
        (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
        (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
        Remove ns_in_resize check.
        (ns_clear_frame_area): Remove resize handle code.

        * nsfns.m (ns_in_resize): Remove.
        (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
        Remove ns_in_resize check.

2012-10-07  Paul Eggert  <eggert@cs.ucla.edu>

        Improve sys_siglist detection.
        * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
        defined as a macro, as is done in Solaris.
        (sys_siglist_entries): New macro.
        (save_strsignal): Use it.
        * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify

        fullscreen/Fullscreen.

        * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
        tobar_height is new.

        * nsterm.m (x_make_frame_visible): Check for fullscreen.
        (ns_fullscreen_hook): Activate old style fullscreen with a timer.
        (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
        (windowDidResize:): Check for correct window if old style fullscreen.
        Capitalize word in comment.  Remove incorrect comment.

        (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
        error in drawing background.
        (toggleFullScreen:): Remove comment.  Rearrange calls.
        Set toolbar values to zero, save old height in tobar_height.
        Restore tool bar height when leaving fullscreen.

2012-10-06  Paul Eggert  <eggert@cs.ucla.edu>

        * keyboard.c (read_char): Remove unnecessary 'volatile's and label.

2012-10-05  Eli Zaretskii  <eliz@gnu.org>

        * w32proc.c (stop_timer_thread): Fix declaration of 'err'.

        * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
        that time stamps of directories could also be changed.
        Don't request the too broad GENERIC_WRITE, only the more restrictive
        FILE_WRITE_ATTRIBUTES access rights.

        * fileio.c (Fset_file_times): Special-case ignoring errors for
        directories only on MSDOS, not on MS-Windows.

2012-10-05  Ikumi Keita  <ikumi@ikumi.que.jp>  (tiny change)

        * minibuf.c (Fcompleting_read): Doc fix.  (Bug#12555)

2012-10-04  Eli Zaretskii  <eliz@gnu.org>

        * profiler.c (handle_profiler_signal): Inhibit pending signals too,
        to avoid similar races.
        * keyboard.c (pending_signals): Now bool, not int.

        Port timers to OpenBSD, plus check for timer failures.
        OpenBSD problem reported by Han Boetes.

        like OpenBSD, which has timer_settime but does not declare it.
        OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
        whether to use itimerspec-related primitives.  All uses of
        HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.

2012-10-02  Paul Eggert  <eggert@cs.ucla.edu>

        Give extra weight to samples after overruns, to attempt to count
        the time more accurately.
        (setup_cpu_timer): Change sampling interval units from ms to ns, since
        the underlying primitives nominally do ns.
        (Fprofiler_cpu_start): Document the change.  Mention that
        the sampling intervals are only approximate.

2012-10-02  Stefan Monnier  <monnier@iro.umontreal.ca>

        * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.

        * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
        case for the special 0 coding-system.

        * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
        (Fmake_overlay): Remove redundant tests.
        (fix_start_end_in_overlays): Remove redundant recentering.

2012-10-02  Juanma Barranquero  <lekktu@gmail.com>

        * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
        Update dependencies.

2012-10-01  Paul Eggert  <eggert@cs.ucla.edu>

        Fix a malloc race condition involving strsignal.
        A signal can arrive in the middle of a malloc, and Emacs's signal
        handler can invoke strsignal, which can invoke malloc, which is
        not portable.  This race condition bug makes Emacs hang on GNU/Linux.
        Fix it by altering the signal handler so that it does not invoke
        strsignal.
        * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
        * process.c (status_message): Use const pointer, in case strsignal
        is #defined to safe_strsignal.
        * sysdep.c (sys_siglist, init_signals): Always define and
        initialize a substitute sys_siglist if the system does not define
        one, even if HAVE_STRSIGNAL.
        (safe_strsignal): Rename from strsignal.  Always define,
        using sys_siglist.  Return a const pointer.
        * syssignal.h (safe_strsignal): New decl.
        (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.

2012-10-01  Eli Zaretskii  <eliz@gnu.org>

        * w32proc.c (timer_loop): Fix code that waits for timer
        expiration, to avoid high CPU usage.

2012-10-01  Stefan Monnier  <monnier@iro.umontreal.ca>

        * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
        (sweep_weak_table): Remove redundant prototypes.

2012-10-01  Fabrice Popineau  <fabrice.popineau@gmail.com>

        * emacs.c: Move the inclusion of TERM_HEADER after including
        windows.h on WINDOWSNT.  This avoids compilation problems with
        MSVC.

2012-10-01  Eli Zaretskii  <eliz@gnu.org>

        * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
        (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
        (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
        as the previous version used 'void *'.

        * ralloc.c (ROUNDUP): Fix last change.
        (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
        'size_t'.

        * w32proc.c <disable_itimers>: New static flag.
        (init_timers): Initialize it to zero, after creating the critical
        sections used by the timer threads.
        (term_timers): Set to 1 before deleting the critical sections.
        (getitimer, setitimer): If disable_itimers is non-zero, return an
        error indication without doing anything.  Reported by Fabrice
        Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
        (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
        return results.
        [!HAVE_SETITIMER]: Behave as the previous version that didn't
        support timers.

        * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
        term_ntproc after all the other bookkeeping, to get timers working
        as long as possible.

2012-10-01  Paul Eggert  <eggert@cs.ucla.edu>

        * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
        Suggested by Juri Linkov in
        <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.

        Prefer plain 'static' to 'static inline' (Bug#12541).
        With static functions, modern compilers inline pretty well by
        themselves; advice from programmers often hurts as much as it helps.
        On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
        this change shrinks the text size of the Emacs executable by 1.1%
        without affecting CPU significantly in my benchmark.

        * syssignal.h (PROFILER_CPU_SUPPORT): Don't define if PROFILING.
        Suggested by Eli Zaretskii in
        <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00811.html>.

2012-09-30  Eli Zaretskii  <eliz@gnu.org>

        * profiler.c (Fprofiler_cpu_stop): Use timer_settime only if
        HAVE_TIMER_SETTIME is defined.

2012-09-30  Paul Eggert  <eggert@cs.ucla.edu>

        Profiler improvements: more-accurate timers, overflow checks.
        * profiler.c: Don't include stdio.h, limits.h, sys/time.h,
        signal.h, setjmp.h.  Include systime.h instead.
        (saturated_add): New function.
        (record_backtrace, current_sample_interval): Use EMACS_INT, not size_t.
        (record_backtrace, handle_profiler_signal): Saturate on fixnum overflow.
        (profiler_timer, profiler_timer_ok) [HAVE_TIMER_SETTIME]:
        New static vars.
        (enum profiler_cpu_running): New enum.
        (profiler_cpu_running): Now of that enum type, not bool.
        All uses changed to store the new value.
        (handle_profiler_signal): Rename from sigprof_handler_1,
        for consistency with other handlers.  Do not check whether
        cpu_log is a hash-table if garbage collecting, since it
        doesn't matter in that case.
        (deliver_profiler_signal): Rename from sigprof_handler,
        for consistency with other handlers.
        (setup_cpu_timer): New function, with much of what used to be in
        Fprofiler_cpu_start.  Check for out-of-range argument.
        Prefer timer_settime if available, and prefer
        thread cputime clocks, then process cputime clocks, then
        monotonic clocks, to the old realtime clock.  Use make_timeval
        to round more-correctly when falling back to setitimer.
        (Fprofiler_cpu_start): Use it.
        (Fprofiler_cpu_stop): Prefer timer_settime if available.
        Don't assume that passing NULL as the 2nd argument of setitimer
        is the same as passing a pointer to all-zero storage.
        Ignore SIGPROF afterwards.
        (malloc_probe): Saturate at MOST_POSITIVE_FIXNUM.
        * sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in
        non-fatal signal handlers.  Ignore SIGPROF on startup.
        * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
        in profiler.c, since sysdep.c now uses it.

        * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.
        Suggested by Eli Zaretskii in
        <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00796.html>.

        * charset.c, charset.h (maybe_unify_char): Now static.
        * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
        Since this stuff is now private to charset.c, there's no need for
        a public macro and no need to inline by hand.

        MS-Windows runtime, not just SIGCHLD.  Actually install the signal
        handlers for signals supported by Windows.  Don't override
        term_ntproc as the handler for SIGABRT.
        (sigaction): Rewrite to call sys_signal instead of duplicating its
        code.
        (sys_kill): Improve commentary.

        * w32.c (term_ntproc): Accept (and ignore) one argument, for
        consistency with a signature of a signal handler.  All callers
        changed.
        (init_ntproc): Accept an argument DUMPING.  If dumping, don't
        install term_ntproc as a signal handler for SIGABRT, as that
        should be done by the dumped Emacs.

        * w32.h (init_ntproc, term_ntproc): Adjust prototypes.

        * w32select.c (term_w32select): Protect against repeated
        invocation by setting clipboard_owner to NULL after calling
        DestroyWindow.

        and term_ntproc to their modified signatures.

        * character.c (char_string, string_char): Remove calls to
        MAYBE_UNIFY_CHAR.  See the discussion starting at

        * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
        (Flibxml_parse_xml_region): Likewise.

        * dispextern.h (struct image_type): Remove arg from init function.

        * image.c (Finit_image_library, lookup_image_type)
        (define_image_type): Remove now-unneeded second arg.
        (init_xpm_functions, init_png_functions, init_jpeg_functions)
        (init_tiff_functions, init_gif_functions, init_svg_functions):
        Arglist and w32_delayed_load calling convention changed.
        (gs_type): Remove init_gs_functions; there is no such function.
        (valid_image_p, make_image): Fix caller to lookup_image_type.

2012-09-23  Paul Eggert  <eggert@cs.ucla.edu>

        Simplify and avoid signal-handling races (Bug#12471).
        * alloc.c (die):
        * sysdep.c (emacs_abort) [HAVE_NTGUI]:
        Avoid recursive loop if there's a fatal error in the function itself.
        * atimer.c (pending_atimers):
        * blockinput.h: Don't include "atimer.h"; no longer needed.
        (interrupt_input_pending): Remove.  All uses removed.
        pending_signals now counts both atimers and ordinary interrupts.
        This is less racy than having three separate pending-signal flags.
        (block_input, unblock_input, totally_unblock_input, unblock_input_to)
        (input_blocked_p):
        Rename from their upper-case counterparts BLOCK_INPUT,
        UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
        INPUT_BLOCKED_P, and turn into functions.  All uses changed.
        This makes it easier to access volatile variables more accurately.
        (BLOCK_INPUT_RESIGNAL): Remove.  All uses replaced by unblock_input ().
        (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
        that's more reliable if the code is buggy and sets
        interrupt_input_blocked to a negative value.  All uses changed.
        * atimer.c (deliver_alarm_signal):
        Remove.  No need to deliver this to the parent; any thread can
        handle this signal now.  All uses replaced by underlying handler.
        * atimer.c (turn_on_atimers):
        * dispnew.c (handle_window_change_signal):
        * emacs.c (handle_danger_signal):
        * keyboard.c (kbd_buffer_get_event):
        Don't reestablish signal handler; not needed with sigaction.
        * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
        (UNBLOCK_INPUT_TO):
        Rework to avoid unnecessary accesses to volatile variables.
        (UNBLOCK_INPUT_TO): Now a function.
        (totally_unblock_input, unblock_input): New decls.
        * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
        (init_data): Remove.  Necessary stuff now done in init_signal.
        * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
        * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
        (fatal_error_code): Remove; no longer needed.
        (terminate_due_to_signal): Rename from fatal_error_backtrace, since
        it doesn't always backtrace.  All uses changed.  No need to reset
        signal to default, since sigaction and/or die does that for us now.
        Use emacs_raise (FOO), not kill (getpid (), FOO).
        (main): Check more-accurately whether we're dumping.
        Move fatal-error setup to sysdep.c
        * floatfns.c: Do not include "syssignal.h"; no longer needed.
        * gtkutil.c (xg_get_file_name, xg_get_font):
        Remove no-longer-needed signal-mask manipulation.
        * keyboard.c, process.c (POLL_FOR_INPUT):
        Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
        * keyboard.c (read_avail_input): Remove.
        All uses replaced by gobble_input.
        (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
        (kbd_buffer_store_event_hold, gobble_input):
        (record_asynch_buffer_change) [USABLE_SIGIO]:
        (store_user_signal_events):
        No need to mess with signal mask.
        (gobble_input): If blocking input and there are terminals, simply
        set pending_signals to 1 and return.  All hooks changed to not
        worry about whether input is blocked.
        (process_pending_signals): Clear pending_signals before processing
        them, in case a signal comes in while we're processing.
        By convention callers now test pending_signals before calling us.
        (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
        New functions, to support changes to blockinput.h.
        (handle_input_available_signal): Now extern.
        (reinvoke_input_signal): Remove.  All uses replaced by
        handle_async_input.
        (quit_count): Now volatile, since a signal handler uses it.
        (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
        All callers changed.  Block SIGINT only if not already blocked.
        Clear sigmask reliably, even if Fsignal returns, which it can.
        Omit unnecessary accesses to volatile var.
        (quit_throw_to_read_char): No need to restore sigmask.
        * keyboard.c (gobble_input, handle_user_signal):
        * process.c (wait_reading_process_output):
        Call signal-handling code rather than killing ourselves.
        * lisp.h: Include <float.h>, for...
        (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
        (pending_signals): Now volatile.
        (syms_of_data): Now const if IEEE floating point.
        (handle_input_available_signal) [USABLE_SIGIO]:
        (terminate_due_to_signal, record_child_status_change): New decls.
        * process.c (create_process): Avoid disaster if memory is exhausted
        while we're processing a vfork, by tightening the critical section
        around the vfork.
        (send_process_frame, process_sent_to, handle_pipe_signal)
        (deliver_pipe_signal): Remove.  No longer needed, as Emacs now
        ignores SIGPIPE.
        (send_process): No need for setjmp/longjmp any more, since the
        SIGPIPE stuff is now gone.  Instead, report an error if errno
        is EPIPE.
        (record_child_status_change): Now extern.  PID and W are now args.
        Return void, not bool.  All callers changed.
        * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
        Remove.  All uses removed.  This bug should be fixed now in a
        different way.
        (wait_for_termination_1): Use waitpid rather than sigsuspend,
        and record the child status change directly.  This avoids the
        need to futz with the signal mask.
        (process_fatal_action): Move here from emacs.c.
        (emacs_sigaction_flags): New function, containing
        much of what used to be in emacs_sigaction_init.
        (emacs_sigaction_init): Use it.  Block nonfatal system signals that are
        caught by emacs, to make races less likely.
        (deliver_process_signal): Rename from handle_on_main_thread.
        All uses changed.
        (BACKTRACE_LIMIT_MAX): Now at top level.
        (thread_backtrace_buffer, threadback_backtrace_pointers):
        New static vars.
        (deliver_thread_signal, deliver_fatal_thread_signal):
        New functions, for more-accurate delivery of thread-specific signals.
        (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
        (deliver_arith_signal): Handle in this thread, not
        in the main thread, since it's triggered by this thread.
        (maybe_fatal_sig): New function.
        (init_signals): New arg DUMPING so that we can be more accurate
        about whether we're dumping.  Caller changed.
        Treat thread-specific signals differently from process-general signals.
        Block all signals while handling fatal error; that's safer.
        xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
        on IEEE hosts.
        When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
        Ignore SIGPIPE unless batch.
        (emacs_backtrace): Output backtrace for the appropriate thread,
        which is not necessarily the main thread.
        * syssignal.h: Include <stdbool.h>.
        (emacs_raise): New macro.
        * xterm.c (x_connection_signal): Remove; no longer needed
        now that we use sigaction.
        (x_connection_closed): No need to mess with sigmask now.
        (x_initialize): No need to reset SIGPIPE handler here, since
        init_signals does this for us now.

2012-09-23  Jan Djärv  <jan.h.d@swipnet.se>

        * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
        background rect may be larger (Bug#12245).

2012-09-23  Chong Yidong  <cyd@gnu.org>

        * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.

2012-09-22  Paul Eggert  <eggert@cs.ucla.edu>

        * .gdbinit: Just stop at fatal_error_backtrace.
        See Stefan Monnier's request in
        <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
        Remove no-longer-used query of system type.

2012-09-22  Chong Yidong  <cyd@gnu.org>

        * search.c (Freplace_match): Doc fix (Bug#12325).

        * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).

2012-09-22  Chong Yidong  <cyd@gnu.org>

        * dispextern.h (struct image_type): Add new slot, storing a type
        initialization function.

        * image.c (define_image_type): Call the image initializer function
        if it is defined.  Arguments and return value changed.
        (valid_image_p, make_image): Callers changed.
        (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
        (gif_type, imagemagick_type, svg_type, gs_type):
        Add initialization functions.
        (Finit_image_library): Call lookup_image_type.
        (CHECK_LIB_AVAILABLE): Macro deleted.
        (lookup_image_type): Call define_image_type here, rather than via
        Finit_image_library, and without using CHECK_LIB_AVAILABLE.
        (syms_of_image): Move define_image_type calls for xbm_type and
        pbm_type to lookup_image_type.

2012-09-22  Eli Zaretskii  <eliz@gnu.org>

        * keyboard.c (timer_check_2): Move calculation of 'timers' and
        'idle_timers' from here ...
        (timer_check): ... to here.  Use Fcopy_sequence to copy the timer
        lists, to avoid infloops when the timer does something stupid,
        like reinvoke itself with the same or smaller time-out.
        (Bug#12447)

2012-09-22  Martin Rudalics  <rudalics@gmx.at>

        * window.c (Fsplit_window_internal): Handle only Qt value of
        Vwindow_combination_limit separately.
        (Qtemp_buffer_resize): New symbol.
        (Vwindow_combination_limit): New default value.
        Rewrite doc-string.

2012-09-22  Eli Zaretskii  <eliz@gnu.org>

2012-09-22  Paul Eggert  <eggert@cs.ucla.edu>

        * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
        or that fprintf is async-signal-safe.  POSIX doesn't require
        either assumption.

2012-09-22  Chong Yidong  <cyd@gnu.org>

        * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
        (Bug#8207).

2012-09-22  Kenichi Handa  <handa@gnu.org>

        * composite.c (composition_reseat_it): Handle the case that a
        grapheme cluster is not covered by a single font (Bug#12352).

2012-09-21  Chong Yidong  <cyd@gnu.org>

        * image.c (define_image_type): Avoid adding duplicate types to
        image_types (Bug#12463).  Suggested by Jörg Walter.

2012-09-21  YAMAMOTO Mitsuharu  <mituharu@math.s.chiba-u.ac.jp>

        lgetfilecon succeeded.
        (Fset_file_selinux_context): Likewise.  (Bug#12444)

2012-09-21  Eli Zaretskii  <eliz@gnu.org>

        * xdisp.c (try_window_reusing_current_matrix): Under bidi
        reordering, locate the cursor by calling set_cursor_from_row; if
        that fails, clear the desired glyph matrix before returning a
        failure indication to the caller.  Fixes leaving garbled display
        when fast scrolling with a down-key.  (Bug#12403)
        (compute_stop_pos_backwards): Fix a typo that caused crashes while
        scrolling through multibyte text.

2012-09-20  Stefan Monnier  <monnier@iro.umontreal.ca>

        * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
        calling mark_vectorlike since that's the one that marks the window.
        (mark_discard_killed_buffers): Mark the final cdr.
        * window.h (struct window): Move prev/next_buffers to the
        non-standard fields.
        * window.c (make_window): Initialize prev/next_buffers manually.

2012-09-20  Paul Eggert  <eggert@cs.ucla.edu>

        Omit unused arg EXPECTED from socket hooks.

        * w32term.c (w32_read_socket):
        * xterm.c (XTread_socket):
        Omit unused arg EXPECTED.  All callers changed.
        (store_user_signal_events): Return void, not int, since callers no
        longer care about the return value.  All uses changed.

2012-09-20  Juanma Barranquero  <lekktu@gmail.com>

        * w32gui.h (XParseGeometry): Do not declare.

2012-09-19  Paul Eggert  <eggert@cs.ucla.edu>

        * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
        Ignore 'expected'.  See Eli Zaretskii in
        <http://bugs.gnu.org/12471#8> (last line).

        * frame.c (read_integer): Remove.  All uses replaced by strtol/strtoul.
        (XParseGeometry): Now static.  Substitute extremal values for
        values that are out of range.

2012-09-19  Jan Djärv  <jan.h.d@swipnet.se>

        top_pos in geometry.

        * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
        (Fx_parse_geometry): If there is a space in string, call
        Qns_parse_geometry, otherwise do as on other terms (Bug#12368).

2012-09-17  Eli Zaretskii  <eliz@gnu.org>

        * search.c (scan_buffer): Use character positions in calls to
        region_cache_forward and region_cache_backward, not byte
        positions.  (Bug#12196)

        * w32term.c (w32_read_socket): Set pending_signals to 1, like
        xterm.c does.  Reported by Daniel Colascione <dancol@dancol.org>.

        * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
        __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
        emacs_blocked_malloc, now deleted.

2012-09-17  Paul Eggert  <eggert@cs.ucla.edu>

        Remove no-longer-needed Solaris 2.4 vfork bug workaround.
        The workaround was for improving performance on Solaris 2.4, but
        is getting in the way now.  Emacs will still work if someone is
        still running Solaris 2.4 in a museum somewhere; Sun dropped
        support for Solaris 2.4 in 2003.
        * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
        * process.c (create_process) [HAVE_WORKING_VFORK]:
        Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
        since Emacs no longer uses vfork on that platform.

2012-09-17  Glenn Morris  <rgm@gnu.org>

        * emacs.c: Use COPYRIGHT.

2012-09-16  Paul Eggert  <eggert@cs.ucla.edu>

        Remove configure's --without-sync-input option (Bug#12450).
        When auditing signal-handling in preparation for cleaning it up,
        I found that SYNC_INPUT has race conditions and would be a real
        pain to fix.  Since it's an undocumented and deprecated
        configure-time option, now seems like a good time to remove it.
        Also see <http://bugs.gnu.org/11080#16>.
        * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)

        [!SYSTEM_MALLOC && !SYNC_INPUT]:
        Remove.  All uses removed.
        (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
        implementation, one that depends on whether the new macro
        XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
        is defined.
        * atimer.c (run_timers, handle_alarm_signal):

        * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
        Now static.

        * font.c (Ffont_shape_gstring): Remove unused local.

2012-09-16  Glenn Morris  <rgm@gnu.org>

        * Makefile.in (clean): No longer run nextstep's clean.

        * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.

2012-09-17  Kenichi Handa  <handa@gnu.org>

2012-09-16  Kenichi Handa  <handa@gnu.org>

        * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster

        * window.c (Fwindow_parameter, Fset_window_parameter):
        Accept any window as argument (Bug#12452).

2012-09-16  Jan Djärv  <jan.h.d@swipnet.se>

        * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
        to ns_term_init to avoid memory leak.

        * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
        explicit retain/release.
        (ns_term_init): Only allow one display.  Initialize outerpool and
        ns_*_types.

2012-09-15  Paul Eggert  <eggert@cs.ucla.edu>

        Port _setjmp fix to POSIXish hosts as well as Microsoft.
        * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
        it's needed on POSIXish hosts that lack _setjmp.  Attempt to solve
        the Microsoft problem in a different way, by altering ../nt/config.nt.

2012-09-15  Eli Zaretskii  <eliz@gnu.org>

        * w32xfns.c:
        * w32uniscribe.c:
        * w32term.c:
        * w32select.c:
        * w32reg.c:

        * w32console.c:
        * w32.c:
        * w16select.c: Remove inclusion of setjmp.h, as it is now included
        by lisp.h.  This completes removal of setjmp.h inclusion
        erroneously announced in the previous commit.  (Bug#12446)

        * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
        more accurate.

        * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
        not defined as a macro.  The latter happens on MS-Windows.
        (Bug#12446)

2012-09-15  Paul Eggert  <eggert@cs.ucla.edu>

        Port better to POSIX hosts lacking _setjmp (Bug#12446).
        * lisp.h: Include <setjmp.h> here, since we use its symbols here.
        Some instances of '#include <setjmp.h>' removed, if the
        only reason for the instance was because "lisp.h" was included.
        (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
        Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
        and _longjmp with the new symbols.  Emacs already uses _setjmp if
        available, so this change affects only POSIXish hosts that have
        sigsetjmp but not _setjmp, such as some versions of Solaris and
        Unixware.  (Also, POSIX-2008 marks _setjmp as obsolescent.)
        * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
        (png_load_body) [HAVE_PNG]:
        (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
        (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
        Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
        since PNG requires jmp_buf.  This is the only exception to the
        general rule that we now use sys_setjmp and sys_longjmp.
        This exception is OK since this code does not change the signal
        mask or longjmp out of a signal handler.

2012-09-14  Paul Eggert  <eggert@cs.ucla.edu>

        * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
        Include "syssignal.h", for 'main_thread'.

2012-09-14  Dmitry Antipov  <dmantipov@yandex.ru>

        Avoid out-of-range marker position (Bug#12426).
        * insdel.c (replace_range, replace_range_2):
        Adjust markers before overlays, as suggested by comments.
        (insert_1_both, insert_from_buffer_1, adjust_after_replace):
        Remove redundant check before calling offset_intervals.

2012-09-14  Martin Rudalics  <rudalics@gmx.at>

        * xdisp.c (Fformat_mode_line): Unconditionally save/restore
        current buffer (Bug#12387).

2012-09-14  Juanma Barranquero  <lekktu@gmail.com>

        * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.

2012-09-13  Paul Eggert  <eggert@cs.ucla.edu>

        Use a more backwards-compatible timer format (Bug#12430).
        * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
        vector element, not from the 4th, since PSECS is now at the end.
        (Fcurrent_idle_time): Doc fix.

2012-09-13  Dmitry Antipov  <dmantipov@yandex.ru>

        Function to mark objects and remove killed buffers at once.
        * alloc.c (discard_killed_buffers): Rename to ...
        (mark_discard_killed buffers) ... new name.  Add marking
        of remaining objects.  Fix comment.  Adjust users.
        (mark_object): Do not touch frame buffer lists here.
        * frame.c (delete_frame): Reset frame buffer lists here.

2012-09-13  Paul Eggert  <eggert@cs.ucla.edu>

        Better workaround for GNOME bug when --enable-gcc-warnings.
        * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
        Instead, disable -Wunused-local-typedefs.  See Dmitry Antipov in
        <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.

        Simplify SIGIO usage (Bug#12408).
        The code that dealt with SIGIO was crufty and confusing, e.g., it
        played tricks like "#undef SIGIO" but these tricks were not used
        consistently.  Simplify mostly by not #undeffing standard symbols,
        e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
        or not as we please) rather than "defined SIGIO" (standard symbol
        that we probably shouldn't #undef).
        * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
        Modules that need it can include it.
        [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
        * dispextern.h (ignore_sigio): New decl.
        * emacs.c (shut_down_emacs): Invoke unrequest_sigio
        unconditionally, since it's now a no-op if !USABLE_SIGIO.
        * emacs.c (shut_down_emacs):
        * keyboard.c (kbd_buffer_store_event_hold):
        Use ignore_sigio rather than invoking 'signal' directly.
        * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
        for FIONREAD.
        (FIONREAD, SIGIO): Do not #undef.
        (tty_read_avail_input): Use #error rather than a syntax error.
        * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
        for I_PIPE, used by SETUP_SLAVE_PTY.
        (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
        * sysdep.c (croak): Remove; no longer needed.  This bit of
        temporary code, with Fred N. Fish's comment that it's temporary,
        has been in Emacs since at least 1992!
        (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
        Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
        * syssignal.h (croak): Remove decl.
        (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
        * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
        now that we're termios-only.
        (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
        * term.c (dissociate_if_controlling_tty): Use #error rather than
        a run-time error.

        Work around GCC and GNOME bugs when --enable-gcc-warnings.
        * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
        to work around GNOME bug 683906.
        * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
        (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
        This works around GCC bug 54561.

2012-09-12  Paul Eggert  <eggert@cs.ucla.edu>

        More fixes for 'volatile' and setjmp/longjmp.
        * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
        * image.c (struct png_load_context) [HAVE_PNG]: New type.
        (png_load_body) [HAVE_PNG]:
        (jpeg_load_body) [HAVE_JPEG]:
        New function, with most of the old parent function's body.
        (png_load) [HAVE_PNG]:
        (jpeg_load) [HAVE_JPEG]:
        Invoke the new function, to avoid longjmp munging our locals.
        (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
        (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
        longjmp is passed 2, as the C standard doesn't guarantee this.
        Instead, store the failure code into mgr->failure_code.

2012-09-12  Stefan Monnier  <monnier@iro.umontreal.ca>

        * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
        (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
        (syms_of_keyboard): Remove support for unread-command-char.

2012-09-12  Eli Zaretskii  <eliz@gnu.org>

        * w32proc.c (sys_kill): If PID is our process ID and the signal is
        SIGABRT, call emacs_abort.  Avoids silently exiting upon assertion
        violation.  (Bug#12426)

2012-09-12  Paul Eggert  <eggert@cs.ucla.edu>

        * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.

2012-09-12  Stefan Monnier  <monnier@iro.umontreal.ca>

        * eval.c: Add `inhibit-debugger'.
        (Qinhibit_debugger): New symbol.
        (call_debugger): Bind it instead of Qdebug_on_error.
        (maybe_call_debugger): Test Vinhibit_debugger.
        (syms_of_eval): Define inhibit-debugger.
        * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
        (syms_of_xdisp): Remove inhibit-debug-on-message.

2012-09-11  Paul Eggert  <eggert@cs.ucla.edu>

        Avoid _setjmp/_longjmp problems with local nonvolatile variables.
        If a nonvolatile local variable is written before a _longjmp to
        the frame containing the variable, and is read after the _longjmp,
        the value read is indeterminate.  Some local variables of type
        'struct handler' and 'struct catchtag' are used in this way, so
        mark each of their slots as volatile if the slot can be set before
        _longjmp and read afterwards.
        * lisp.h (struct handler): var and chosen_clause are now volatile.
        (struct catchtag): val, next, and pdlcount are now volatile.

        * bidi.c (bidi_push_it, bidi_pop_it):
        * fns.c (copy_hash_table):
        * image.c (define_image_type):
        * keyboard.c (kbd_buffer_store_event_hold):
        * process.c (Fprocess_send_eof):
        * xfaces.c (x_create_gc) [HAVE_NS]:
        * xgselect.c (xg_select):
        Prefer assignment to memcpy when either will do.

        * alloc.c (discard_killed_buffers): Tune and simplify a bit.
        Use pointer-to-a-pointer to simplify and avoid a NILP check each
        time an item is removed.  No need to mark this function 'inline';
        the compiler knows better than we do.

2012-09-11  Jan Djärv  <jan.h.d@swipnet.se>

        * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
        (updateFrameSize:): Add delay parameter to updateFrameSize, send it
        to change_frame_size (Bug#12388).
        (windowDidResize:): Pass YES to updateFrameSize.

        * nsterm.h: Add delay parameter to updateFrameSize.

2012-09-11  Dmitry Antipov  <dmantipov@yandex.ru>

        Discard killed buffers from deleted window and frame objects.
        This reduces an amount of references to killed buffers and
        helps GC to reclaim them faster.
        * alloc.c (discard_killed_buffers): New function.
        (mark_object): Use it for deleted windows and frames.
        (mark_object): If symbol's value is set up for a killed buffer
        or deleted frame, restore its global binding.
        * data.c (swap_in_global_binding): Add GC notice.
        (swap_in_symval_forwarding): Use convenient set_blv_where.
        * window.c (wset_next_buffers, wset_prev_buffers): Move ...
        * window.h: ... to here.

2012-09-11  Dmitry Antipov  <dmantipov@yandex.ru>

        Convenient macro to check whether the buffer is live.
        * buffer.h (BUFFER_LIVE_P): New macro.
        * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
        * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.

2012-09-11  YAMAMOTO Mitsuharu  <mituharu@math.s.chiba-u.ac.jp>

        * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
        composition cases (Bug#12364).

        * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
        overhang of succeeding glyphs overlapping box cursor.

        * w32term.c (x_draw_glyph_string): Likewise.

2012-09-11  Paul Eggert  <eggert@cs.ucla.edu>

        Simplify, document, and port floating-point (Bug#12381).
        The porting part of this patch fixes bugs on non-IEEE platforms
        with frexp, ldexp, logb.
        * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
        Now static.
        * floatfns.c: Simplify discussion of functions that Emacs doesn't
        support, by removing commented-out code and briefly listing the
        C89 functions excluded.  The commented-out stuff was confusing
        maintenance, e.g., we thought we needed cbrt but it was commented out.
        (logb): Remove decl; no longer needed.
        (isfinite): New macro, if not already supplied.
        (isnan): Don't replace any existing macro.
        (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
        are present on all C89 platforms.
        (Ffrexp): Do not special-case zero, as frexp does the right thing
        for that case.
        (Flogb): Do not use logb, as it doesn't have the desired meaning
        on hosts that use non-base-2 floating point.  Instead, stick with
        frexp, which is C89 anyway.  Do not pass an infinity or a NaN to
        frexp, to avoid getting an unspecified result.

        * xdisp.c (Qinhibit_debug_on_message): Now static.

2012-09-10  Jan Djärv  <jan.h.d@swipnet.se>

        * nsterm.m (ns_update_begin): Set clip path to whole view by using
        NSBezierPath (Bug#12131).

2012-09-10  Chong Yidong  <cyd@gnu.org>

        * fns.c (Fdelq, Fdelete): Doc fix.

2012-09-10  Paul Eggert  <eggert@cs.ucla.edu>

        * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
        (XSETFLOAT, XSETMISC): Parenthesize macro bodies.

2012-09-09  Stefan Monnier  <monnier@iro.umontreal.ca>

        * lisp.h (make_lisp_ptr): New macro to replace XSET.
        (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
        Use it.

2012-09-09  Eli Zaretskii  <eliz@gnu.org>

        * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
        left fringe if the window has a left margin.  This avoids leaving
        traces of the cursor because its leftmost pixel is not drawn over.

        * dispnew.c (update_window_line): When the left margin area of a
        screen line is updated, set the redraw_fringe_bitmaps_p flag of
        that screen line.  (Bug#12277)

2012-09-09  Paul Eggert  <eggert@cs.ucla.edu>

        Assume C89 or later for math functions (Bug#12381).
        This simplifies the code, and makes it a bit smaller and faster,
        and (most important) makes it easier to clean up signal handling
        since we can stop worring about floating-point exceptions in
        library code.  That was a problem before C89, but the problem
        went away many years ago on all practical Emacs targets.
        * data.c, image.c, lread.c, print.c:
        Don't include <math.h>; no longer needed.
        * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
        might be autoconfigured, as that never happens.
        * data.c (fmod):
        * doprnt.c (DBL_MAX_10_EXP):
        * print.c (DBL_DIG):
        Remove.  C89 or later always defines these.
        * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
        (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
        (arith_error, domain_error, domain_error2):
        Remove all this pre-C89 cruft.  Do not include <errno.h> as that's
        no longer needed -- we simply return what C returns.  All uses removed.
        (IN_FLOAT, IN_FLOAT2): Remove.  All uses replaced with
        the wrapped code.
        (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
        Remove.  All uses expanded, as these macros are no longer used
        more than once and are now more trouble than they're worth.
        (Ftan): Use tan, not sin / cos.
        (Flogb): Assume C89 frexp.
        (fmod_float): Assume C89 fmod.
        (matherr) [HAVE_MATHERR]: Remove; no longer needed.
        (init_floatfns): Remove.  All uses removed.

2012-09-08  Jan Djärv  <jan.h.d@swipnet.se>

        * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
        compositeToPoint for OSX < 10.6 (Bug#12390).

2012-09-08  Paul Eggert  <eggert@cs.ucla.edu>

        * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
        This produces more-accurate results.

2012-09-08  Jan Djärv  <jan.h.d@swipnet.se>

        * nsterm.m (updateFrameSize): Call setFrame: on the view when size
        changes (Bug#12088).

2012-09-08  Chong Yidong  <cyd@gnu.org>

        * syntax.c (Fstring_to_syntax): Doc fix.

2012-09-08  Jan Djärv  <jan.h.d@swipnet.se>

        * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
        in the internal border.
        (x_set_window_size): Remove static variables and their usage.
        (ns_redraw_scroll_bars): Fix NSTRACE arg.
        (ns_after_update_window_line, ns_draw_fringe_bitmap):
        Remove fringe/internal border adjustment (Bug#11052).
        (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
        (ns_draw_window_cursor): Remove fringe/internal border adjustment.
        (ns_fix_rect_ibw): Remove.
        (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
        (ns_dumpglyphs_box_or_relief): Ditto.
        (ns_maybe_dumpglyphs_background): Remove fringe/internal border
        adjustment.
        (ns_dumpglyphs_image): Ditto.
        (ns_dumpglyphs_stretch): Fix coding style.  Remove fringe/internal
        border adjustment.
        (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
        their usage.  Add fringe_extended_p and its use as in other terms.
        (ns_judge_scroll_bars): Code style fix.  Call updateFrameSize if
        scroll bar was removed.
        (updateFrameSize): New function.
        (windowDidResize): Move code to updateFrameSize and call it.

        * nsterm.h (EmacsView): Add updateFrameSize.

2012-09-07  Chong Yidong  <cyd@gnu.org>

        * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).

        * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).

2012-09-07  Paul Eggert  <eggert@cs.ucla.edu>

        More signal-handler cleanup (Bug#12327).
        * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
        Problem introduced when merging patches.  Noted by Eli Zaretskii in
        <http://bugs.gnu.org/12327#67>.
        * floatfns.c: Comment fix.
        * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
        SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
        and anyway the declaration is harmless even if SIGDANGER is not defined.
        * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
        defined BROKEN_FIONREAD).  systty.h formerly did this, but other
        source files not surprisingly expected syssignal.h to define, or
        not define, SIGIO, and it's cleaner to do it that way, for consistency.
        Include <sys/ioctl.h>, for FIONREAD.
        * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
        This eliminates a problem whereby other files mysteriously had
        to include "syssignal.h" before including "systty.h" if they
        wanted to use "#ifdef SIGIO".

2012-09-07  Eli Zaretskii  <eliz@gnu.org>

        * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.

        * w32.c (sigemptyset): Empty the set.
        (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.

        * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.

2012-09-07  Dmitry Antipov  <dmantipov@yandex.ru>

        * alloc.c (mark_buffer): Revert unsafe marking optimization.
        (mark_object): Likewise for frame objects.

2012-09-07  Paul Eggert  <eggert@cs.ucla.edu>

        * syssignal.h (handle_on_main_thread): Always declare,
        even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
        This ports to platforms without HAVE_PTHREAD.

2012-09-06  Paul Eggert  <eggert@cs.ucla.edu>

        Signal-handler cleanup (Bug#12327).
        Emacs's signal handlers were written in the old 4.2BSD style with
        sigblock and sigmask and so forth, and this led to some
        inefficiencies and confusion.  Rewrite these to use
        pthread_sigmask etc. without copying signal sets around.  Also,
        get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
        'signal', and instead use functions that do not attempt to take
        over the system name space.  This patch causes Emacs's text
        segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
        * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
        Do not include <signal.h> or "syssignal.h", as these
        modules do not use signals.
        * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
        * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
        Do not include <signal.h>, as "syssignal.h" does that for us now.
        * atimer.c (sigmask_atimers): New function.
        (block_atimers, unblock_atimers): New functions,
        replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
        All uses replaced.
        * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
        no longer needed here.
        * emacs.c (main): Inspect existing signal handler with sigaction,
        so that there's no need to block and unblock SIGHUP.
        * sysdep.c (struct save_signal): New member 'action', replacing
        old member 'handler'.
        (save_signal_handlers, restore_signal_handlers):
        Use sigaction instead of 'signal' to save and restore.
        (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
        New function.  All users of 'signal' modified to use set_sighandler
        if they're writeonly, and to use sys_signal if they're read+write.
        (emacs_sigaction_init, forwarded_signal): New functions.
        (sys_signal): Remove.  All uses replaced by calls to sigaction
        and emacs_sigaction_init, or by direct calls to 'signal'.
        (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
        (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
        all uses replaced by pthread_sigmask etc. calls.
        * syssignal.h: Include <signal.h>.
        (emacs_sigaction_init, forwarded_signal): New decls.
        (SIGMASKTYPE): Remove.  All uses replaced by its definiens, sigset_t.
        (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
        (sigmask, sys_sigmask): Remove; no longer needed.
        (sigpause): Remove.  All uses replaced by its definiens, sigsuspend.
        (sigblock, sigunblock, sigfree):
        (sigsetmask) [!defined sigsetmask]:
        Remove.  All uses replaced by pthread_sigmask.
        (signal): Remove.  Its remaining uses (with SIG_DFL and SIG_IGN)
        no longer need to be replaced, and its typical old uses
        are now done via emacs_sigaction_init and sigaction.
        (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
        (sys_sigdel): Remove; unused.
        (NSIG): Remove a FIXME; the code's fine.  Remove an unnecessary ifdef.

2012-09-06  Eli Zaretskii  <eliz@gnu.org>

        * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
        SIGCHLD handling on systems that don't have WNOHANG.  (Bug#12327)

2012-09-06  Dmitry Antipov  <dmantipov@yandex.ru>

        Explicitly mark buffer_defaults and buffer_local_symbols.
        * alloc.c (Fgarbage_collect): Mark buffer_defaults and
        mark_local_symbols here.
        (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
        since special buffers aren't marked here any more.
        (allocate_buffer): Chain new buffer with all_buffers here...
        * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
        not here.
        (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
        (syms_of_buffer): Remove staticpro of the above.
        (init_buffer_once): Set names for buffer_defaults and
        buffer_local_symbols.

2012-09-06  Paul Eggert  <eggert@cs.ucla.edu>

        Use bool for booleans in font-related modules.
        * font.c (font_intern_prop, font_style_to_value)
        (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
        (generate_otf_features, font_check_otf_features, font_check_otf)
        (font_match_p, font_list_entities, font_at):
        * fontset.c (fontset_id_valid_p, reorder_font_vector
        (fontset_find_font, Fset_fontset_font)
        (face_suitable_for_char_p) [0]:
        * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
        (ftfont_open, ftfont_text_extents, ftfont_check_otf):
        (m17n_flt_initialized, ftfont_shape_by_flt):
        * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
        * nsfont.m (nsfont_draw):
        * w32font.c (w32font_draw):
        * w32term.c (x_draw_glyphless_glyph_string_foreground):
        Use bool for booleans.
        * font.h: Adjust to above API changes.
        (struct font, struct font_driver, struct font_driver_list):
        Use bool for booleans.
        (struct font): Remove useless member encoding_type.
        All users removed.
        * fontset.c, xftfont.c: Omit unnecessary static decls.

2012-09-06  Dmitry Antipov  <dmantipov@yandex.ru>

        * alloc.c (mark_object): Revert window marking code
        since it's unsafe for the Fset_window_configuration.

2012-09-05  Paul Eggert  <eggert@cs.ucla.edu>

        Fix race conditions with signal handlers and errno (Bug#12327).
        Be more systematic about preserving errno whenever a signal
        handler returns, even if it's not in the main thread.  Do this by
        renaming signal handlers to distinguish between signal delivery
        and signal handling.  All uses changed.
        * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
        * data.c (deliver_arith_signal): Rename from arith_error.
        * dispnew.c (deliver_window_change_signal): Rename from
        window_change_signal.
        * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
        (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
        * keyboard.c (deliver_input_available_signal): Rename from
        input_available_signal.
        (deliver_user_signal): Rename from handle_user_signal.
        (deliver_interrupt_signal): Rename from interrupt_signal.
        * process.c (deliver_pipe_signal): Rename from send_process_trap.
        (deliver_child_signal): Rename from sigchld_handler.
        * atimer.c (handle_alarm_signal):
        * data.c (handle_arith_signal):
        * dispnew.c (handle_window_change_signal):
        * emacs.c (handle_fatal_signal, handle_danger_signal):
        * keyboard.c (handle_input_available_signal):
        * keyboard.c (handle_user_signal, handle_interrupt_signal):
        * process.c (handle_pipe_signal, handle_child_signal):
        New functions, with the actual signal-handling code taken from the
        original respective signal handlers, sans the sporadic attempts to
        preserve errno, since that's now done by handle_on_main_thread.
        * atimer.c (alarm_signal_handler): Remove unnecessary decl.
        * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
        * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
        Move to sysdep.c.
        (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
        Move initialization of main_thread to sysdep.c's init_signals.
        * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
        our usage, and simplifies the mainline code.
        (record_child_status_change): New static function, as a helper
        for handle_child_signal, and with most of the old child handler's
        contents.
        (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
        (handle_child_signal): Use the above.
        * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
        Moved here from emacs.c.
        (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
        code moved here from emacs.c's main function.
        * sysdep.c, syssignal.h (handle_on_main_thread): New function,
        replacing the old SIGNAL_THREAD_CHECK.  All uses changed.
        This lets callers save and restore errno properly.

2012-09-05  Dmitry Antipov  <dmantipov@yandex.ru>

        Remove redundant or unused things here and there.
        * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
        * conf_post.h (RE_TRANSLATE): Use char_table_translate.
        * editfns.c (Fcompare_buffer_substrings): Likewise.
        * frame.h (struct terminal, struct font_driver_list):
        Remove redundant declarations.
        * window.h (Qleft, Qright): Likewise.

2012-09-05  Dmitry Antipov  <dmantipov@yandex.ru>

        Do not mark objects from deleted buffers, windows and frames.
        * alloc.c (mark_buffer): Mark just the buffer if it is dead.
        (mark_object): Likewise for windows and frames.

2012-09-05  Dmitry Antipov  <dmantipov@yandex.ru>

        * alloc.c (valid_lisp_object_p): Treat killed buffers,
        buffer_defaults and buffer_local_symbols as valid objects.
        Return special value to denote them.

2012-09-05  Paul Eggert  <eggert@cs.ucla.edu>

        * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
        * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
        (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
        (file_name_absolute_p, Fsubstitute_in_file_name):
        (check_executable, check_writable, Ffile_accessible_directory_p)
        (Fset_file_selinux_context, Fdefault_file_modes)
        (Finsert_file_contents, choose_write_coding_system)
        (Fwrite_region, build_annotations, a_write, e_write)
        (Fdo_auto_save):
        * filelock.c (boot_time_initialized, get_boot_time)
        (get_boot_time_1, lock_file_1, within_one_second):
        * floatfns.c (in_float):
        * fns.c (concat, internal_equal, Frequire, base64_encode_1)
        (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
        (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
        * lisp.h (struct Lisp_Hash_Table.cmpfn):
        * window.c (compare_window_configurations):
        Use bool for booleans.
        * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
        (Fdefault_file_modes): Now mode_t, not int, for modes.
        (Fdo_auto_save): Set a boolean to 1 rather than using ++.
        (internal_delete_file): Now returns void, not a (boolean) int,
        since nobody was looking at the return value.
        * lisp.h, window.h: Adjust to above API changes.

        * xdisp.c (set_message): Simplify and reindent last change.

2012-09-05  Juanma Barranquero  <lekktu@gmail.com>

        * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.

2012-09-04  Lars Ingebrigtsen  <larsi@gnus.org>

        * eval.c (call_debugger): Make the function non-static so that we
        can call it from set_message.

        * xdisp.c (set_message): Implement the new variable `debug-on-message'.
        (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.

2012-09-04  Paul Eggert  <eggert@cs.ucla.edu>

        Give more-useful info on a fatal error (Bug#12328).
        * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
        (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
        of doing the work ourselves.
        * emacs.c (fatal_error_signal): Let fatal_error_backtrace
        do most of the work.
        (fatal_error_backtrace): New function, taken from the guts
        of the old fatal_error_signal, but with a new option to output
        a backtrace.
        (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
        info about the signal than just its number.
        * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
        * sysdep.c: Include <execinfo.h>
        (emacs_backtrace): New function, taken partly from the previous
        code of the 'die' function.
        (emacs_abort): Call fatal_error_backtrace rather than abort.

2012-09-04  Stefan Monnier  <monnier@iro.umontreal.ca>

        * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
        eager (load-time) macro-expansion.
        * lisp.mk (lisp): Add macroexp.

2012-09-04  Paul Eggert  <eggert@cs.ucla.edu>

        Simplify redefinition of 'abort' (Bug#12316).
        Do not try to redefine the 'abort' function.  Instead, redo
        the code so that it calls 'emacs_abort' rather than 'abort'.
        This removes the need for the NO_ABORT configure-time macro
        and makes it easier to change the abort code to do a backtrace.
        * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
        * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
        Remove; sysdep.c's emacs_abort now takes its place.
        * lisp.h (emacs_abort): New decl.  All calls from Emacs code to
        'abort' changed to use 'emacs_abort'.
        * msdos.c (dos_abort) [defined abort]: Remove; not used.
        (abort) [!defined abort]: Rename to ...
        (emacs_abort): ... new name.
        * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
        the place of the old 'abort' in emacs.c.
        * w32.c, w32fns.c (abort): Do not #undef.
        * w32.c (emacs_abort): Rename from w32_abort.

2012-09-04  Eli Zaretskii  <eliz@gnu.org>

        * w32uniscribe.c (uniscribe_shape): Reverse the sign of
        offsets[j].dv, since the y axis of the screen coordinates points
        down, while the y axis of the font definition coordinates points
        up.  This fixes display of Arabic diacritics such as KASRA and
        KASRATAN.  (Bug#11860)

2012-09-04  Paul Eggert  <eggert@cs.ucla.edu>

        Be more systematic about _setjmp vs setjmp.
        * alloc.c (test_setjmp, mark_stack):
        * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
        (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
        (png_load, my_error_exit, jpeg_load):
        * process.c (send_process_trap, send_process):
        Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
        The underscored versions are up to 30x faster on some hosts.
        Formerly, the code used setjmp+longjmp sometimes and
        _setjmp+_longjmp at other times, with no particular reason to
        prefer setjmp+longjmp.

2012-09-03  Paul Eggert  <eggert@cs.ucla.edu>

        Fix minor problem found by static checking.
        * buffer.c (Fdelete_all_overlays): Return nil.

2012-09-03  Martin Rudalics  <rudalics@gmx.at>

        * buffer.c (Fdelete_all_overlays): New function.

2012-09-03  Chong Yidong  <cyd@gnu.org>

        * gtkutil.c: Add extern decl for Qxft.

2012-09-02  Paul Eggert  <eggert@cs.ucla.edu>

        * emacs.c, eval.c: Use bool for boolean.
        * emacs.c (initialized, inhibit_window_system, running_asynch_code):
        (malloc_using_checking) [DOUG_LEA_MALLOC]:
        (display_arg) [HAVE_X_WINDOWS || HAVE_NS]:
        (noninteractive, no_site_lisp, fatal_error_in_progress, argmatch)
        (main, decode_env_path, Fdaemon_initialized):
        * eval.c (call_debugger, Finteractive_p, interactive_p):
        (unwind_to_catch, Fsignal, wants_debugger, skip_debugger)
        (maybe_call_debugger, Fbacktrace):
        * process.c (read_process_output, exec_sentinel):
        Use bool for booleans.
        * emacs.c (shut_down_emacs): Omit unused boolean argument NO_X.
        All callers changed.
        * eval.c (interactive_p): Omit always-true boolean argument
        EXCLUDE_SUBRS_P.  All callers changed.
        * dispextern.h, lisp.h: Reflect above API changes.
        * firstfile.c (dummy): Use the address of 'main', whose signature
        won't change, instead of the address of 'initialize', whose
        signature just changed from int to bool.
        * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
        * msdos.c (fatal_error_in_progress): ... from here.
        * xdisp.c (redisplaying_p): Now a boolean.  Set it to 1 instead
        of incrementing it.
        (redisplay_internal, unwind_redisplay): Simply clear
        REDISPLAYING_P when unwinding, instead of saving its previous,
        always-false value and then restoring it.

        Clean up some extern decls.
        Mostly, this hoists extern decls out of .c files and into .h files.
        That way, we're more likely to catch errors if the interfaces change.
        * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
        declare xg_mark_data.
        * dispextern.h (x_frame_parm_handlers):
        * font.h (Qxft):
        * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)
        (Qextra_light, Qlight, Qsemi_light, Qsemi_bold, Qbold, Qextra_bold)
        (Qultra_bold, Qoblique, Qitalic):
        Move extern decl here from .c file.
        * alloc.c (xg_mark_data) [USE_GTK]:
        * doc.c (Qclosure):
        * eval.c (Qlexical_binding):
        * fns.c (time) [!HAVE_UNISTD_H]:
        * gtkutil.c (Qxft, Qnormal, Qextra_light, Qlight, Qsemi_light)
        (Qsemi_bold, Qbold, Qextra_bold, Qultra_bold, Qoblique, Qitalic):

        * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
        * window.h (decode_valid_window):
        Remove decls.

        * character.c, charset.c, chartab.c: Use bool for booleans.
        * character.c (lisp_string_width, string_count_byte8)
        (string_escape_byte8):
        * charset.c (charset_map_loaded, load_charset_map, read_hex):
        (load_charset_map_from_file, map_charset_chars)
        (Fdefine_charset_internal, define_charset_internal)
        (Fdeclare_equiv_charset, find_charsets_in_text)
        (Ffind_charset_region, char_charset, Fiso_charset):
        * chartab.c (sub_char_table_ref, sub_char_table_ref_and_range)
        (sub_char_table_set, sub_char_table_set_range)
        (char_table_set_range, optimize_sub_char_table)
        (map_sub_char_table):
        Use bool for boolean.
        * character.c (str_to_unibyte): Omit last boolean argument; it was
        always 0.  All callers changed.
        * character.h, charset.h: Adjust to match previous changes.
        * character.h (char_printable_p): Remove decl of nonexistent function.
        * charset.h (struct charset): Members code_linear_p, iso_chars_96,
        ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
        are all boolean, so make them single-bit bitfields.

        * lisp.h (ASET): Remove attempt to detect side effects.
        It was meant to be temporary and it often doesn't work,
        because when IDX has side effects the behavior of IDX==IDX
        is undefined.  See Stefan Monnier in
        <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.

2012-08-26  Barry OReilly  <gundaetiapo@gmail.com>  (tiny change)

        * lisp.h (functionp): New function (extracted from Ffunctionp).
        (FUNCTIONP): Use it.
        * eval.c (Ffunctionp): Use it.

2012-08-25  Paul Eggert  <eggert@cs.ucla.edu>

        * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
        as that's faster and simpler than static storage.  Don't bother
        with the g_main_context_query overhead if g_main_context_pending
        says no events are pending.
        (gfds, gfds_size): Remove these static vars.
        (xgselect_initialize): Remove; no longer needed.
        All uses and decls removed.

        * emacs.c (fatal_error_signal_hook): Remove.
        All uses removed.  This leftover from old code was always 0.

        * casefiddle.c, casetab.c, category.c: Use bool for boolean.
        * casefiddle.c (casify_object, casify_region):
        * casetab.c (set_case_table):
        * category.c, category.h (word_boundary_p):
        * category.h (CHAR_HAS_CATEGORY):
        Use bool for booleans, instead of int.

2012-08-25  Eli Zaretskii  <eliz@gnu.org>

        * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.

2012-08-25  Paul Eggert  <eggert@cs.ucla.edu>

        On assertion failure, print backtrace if available.
        * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
        (die) [ENABLE_CHECKING]: Print a backtrace if available.
        * Makefile.in (LIB_EXECINFO): New macro.
        (LIBES): Use it.

        * bytecode.c, callint.c, callproc.c: Use bool for boolean.
        * bytecode.c (exec_byte_code):
        * callint.c (check_mark, Fcall_interactively):
        * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
        (getenv_internal, sync_process_alive, call_process_exited):
        * lisp.h (USE_SAFE_ALLOCA):
        Use bool for booleans, instead of int.
        * lisp.h, process.h: Adjust prototypes to match above changes.
        * callint.c (Fcall_interactively): Don't assume the mark's
        offset fits in 'int'.

2012-08-24  Paul Eggert  <eggert@cs.ucla.edu>

        * buffer.c, buffer.h: Use bool for boolean.
        * buffer.c (reset_buffer_local_variables)
        (buffer_lisp_local_variables, Fset_buffer_modified_p)
        (Frestore_buffer_modified_p, Fset_buffer_multibyte):
        (overlays_at, overlays_in, mouse_face_overlay_overlaps)
        (overlay_touches_p, overlay_strings, Foverlay_put)
        (report_overlay_modification, call_overlay_mod_hooks):
        (mmap_enlarge, mmap_set_vars):
        * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
        Use bool for booleans, instead of int.
        * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
        since the 1-or-0 return value is always ignored anyway.
        (mmap_initialized_p):
        * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
        * buffer.h, lisp.h: Adjust prototypes to match above changes.

2012-08-23  Paul Eggert  <eggert@cs.ucla.edu>

        * bidi.c: Use bool for boolean.
        This is a bit more readable, and makes the text segment of bidi.o
        0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
        Presumably it's faster too.
        (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
        Now bool.
        (bidi_cache_find_level_change, bidi_cache_iterator_state)
        (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
        (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
        (bidi_explicit_dir_char, bidi_level_of_next_char)
        (bidi_find_other_level_edge, bidi_move_to_visually_next):
        Use bool for booleans, instead of int.
        * dispextern.h (bidi_init_it, bidi_paragraph_init)
        (bidi_unshelve_cache): Adjust decls to match code.

2012-08-23  Martin Rudalics  <rudalics@gmx.at>

        * keyboard.c (Fposn_at_x_y): Do not allow internal window as
        argument.

2012-08-23  Paul Eggert  <eggert@cs.ucla.edu>

        * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
        * atimer.h: Include <stdbool.h>.

2012-08-22  Dan Nicolaescu  <dann@gnu.org>

        * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
        compile time tests instead of run time tests on systems that do
        not use them.
        (FRAME_MAC_P): Remove leftover from deleted code.
        * frame.c (syms_of_frame): Remove leftover from deleted code.

2012-08-22  Jan Djärv  <jan.h.d@swipnet.se>

        * nsterm.m (insertText:): Don't clear modifiers if code is space.

2012-08-22  Paul Eggert  <eggert@cs.ucla.edu>

        * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
        Otherwise, the compiler complains about (A?B:C) where B is void
        and C is Lisp_Object.  This fixes an incompatibility with Sun C 5.12.
        (fontset_add): Return void, for FONTSET_ADD.

2012-08-21  Paul Eggert  <eggert@cs.ucla.edu>

        * alloc.c: Use bool for booleans.
        (gc_in_progress, abort_on_gc)
        (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
        (dont_register_blocks) [GC_MALLOC_CHECK]:
        (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
        (check_string_bytes, make_specified_string, memory_full)
        (live_string_p, live_cons_p, live_symbol_p, live_float_p)
        (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
        (mark_stack, valid_pointer_p, make_pure_string)
        (Fgarbage_collect, survives_gc_p, gc_sweep):
        Use bool for booleans, instead of int.
        (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
        Remove unused local.
        * alloc.c (PURE_POINTER_P):
        * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
        * editfns.c (Fformat):
        * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
        (Fdo_auto_save):
        * fns.c (sweep_weak_table):
        * lisp.h (suppress_checking, push_message, survives_gc_p)
        (make_pure_string, gc_in_progress, abort_on_gc):
        * lread.c (readchar, read1):
        * print.c (Fprin1_to_string):
        * xdisp.c (push_message):
        Use bool for booleans affected directly or indirectly by
        alloc.c's changes.

        Make recently-introduced setters macros.
        * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
        (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
        (set_fontset_default, set_fontset_fallback): Rename from their
        upper-case counterparts, and make them functions rather than macros.
        This is more consistent with the other recently-introduced setters.
        These don't need to be inline, since they're local.

2012-08-21  Jan Djärv  <jan.h.d@swipnet.se>

        * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
        the loop (Bug#12247).

2012-08-21  Paul Eggert  <eggert@cs.ucla.edu>

        * lisp.h (vcopy): Use memcpy rather than our own loop.
        This fixes a performance regression introduced by the recent
        addition of vcopy.  This means 'vcopy' will need to be modified
        for a copying collector, but that's OK.  Also, tighten the
        checking in the assertion.

2012-08-21  Eli Zaretskii  <eliz@gnu.org>

        * w32uniscribe.c (uniscribe_shape): Fix producing gstring
        components for RTL text (Bug#11860).  Adjust X-OFFSET of each
        non-base glyph for the width of the base character, according to
        what x_draw_composite_glyph_string_foreground expects.
        Generate WADJUST value according to composition_gstring_width's
        expectations, to produce correct width of the composed character.
        Reverse the sign of the DU offset produced by ScriptPlace.

2012-08-21  Paul Eggert  <eggert@cs.ucla.edu>

        * dbusbind.c (xd_remove_watch): Do not assume C99 comments.

2012-08-21  Dmitry Antipov  <dmantipov@yandex.ru>

        Avoid direct writes to contents member of struct Lisp_Vector.
        * lisp.h (vcopy): New function to copy data into vector.
        * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
        * fns.c (Ffillarray): Use ASET.
        * keyboard.c (timer_check_2): Use AREF and ASET.
        (append_tool_bar_item, Frecent_keys): Use vcopy.
        * lread.c (read_vector): Use ASET.
        * msdos.c (Frecent_doskeys): Use vcopy.
        * xface.c (Finternal_copy_lisp_face): Use vcopy.
        (Finternal_merge_in_global_face): Use ASET and vcopy.
        * xfont.c (xfont_list_pattern): Likewise.

2012-08-21  Martin Rudalics  <rudalics@gmx.at>

        * window.c (Fwindow_point): For the selected window always return
        the position of its buffer's point.
        (Fset_window_point): For the selected window always go in its
        buffer to the specified position.

2012-08-21  Dmitry Antipov  <dmantipov@yandex.ru>

        Setter macros for fontsets.
        * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
        (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
        (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
        Adjust users.

2012-08-20  Glenn Morris  <rgm@gnu.org>

        * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
        Don't assume that `ln -f' works.

2012-08-20  Eli Zaretskii  <eliz@gnu.org>

        * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
        and later about non-assignments with no effect.  See discussion at
        http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
        details.

2012-08-20  Dmitry Antipov  <dmantipov@yandex.ru>

        Inline setter functions for Lisp_Objects slots of struct specbinding.
        * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
        Adjust users.

2012-08-20  Martin Rudalics  <rudalics@gmx.at>

        * window.c (select_window): Always make selected window's buffer
        current.

2012-08-20  Dmitry Antipov  <dmantipov@yandex.ru>

        Use AREF and ASET for docstrings of category tables.
        * category.h (CATEGORY_DOCSTRING): Use AREF.
        (SET_CATEGORY_DOCSTRING): Use ASET.
        * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.

2012-08-20  Dmitry Antipov  <dmantipov@yandex.ru>

        Inline setter functions for hash table members.
        * lisp.h (set_hash_key, set_hash_value, set_hash_next)
        (set_hash_hash, set_hash_index): Rename with _slot suffix.
        (set_hash_key_and_value, set_hash_index, set_hash_next)
        (set_hash_hash): New functions.
        * charset.c, fns.c: Adjust users.

2012-08-20  Dmitry Antipov  <dmantipov@yandex.ru>

        * buffer.h (per_buffer_default, set_per_buffer_default)
        (per_buffer_value, set_per_buffer_value): New functions.
        (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
        * buffer.c, data.c: Adjust users.

2012-08-20  Juanma Barranquero  <lekktu@gmail.com>

        * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.

2012-08-19  Paul Eggert  <eggert@cs.ucla.edu>

        Rely on <config.h> + <unistd.h> to declare 'environ',
        as gnulib does this if the system doesn't.
        * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
        Remove declaration.  MS-Windows declares it on stdlib.h which is
        included by conf_post.h.
        * emacs.c (environ) [DOUG_LEA_MALLOC]:
        * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
        * vm-limit.c: Include <unistd.h>, for 'environ'.

        * unexaix.c, unexcoff.c: Include "mem-limits.h".
        (start_of_data): Remove decl; mem-limits.h provides it.

        * xdisp.c (handle_invisible_prop): Make it a bit faster
        and avoid a gcc -Wmaybe-uninitialized diagnostic.

2012-08-19  Chong Yidong  <cyd@gnu.org>

        * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
        ends (Bug#3874).

2012-08-19  Andreas Schwab  <schwab@linux-m68k.org>

        * .gdbinit: Use call instead of set when calling a function in the
        inferior.

        * data.c (set_internal): Don't use set_blv_found.
        (Fkill_local_variable): Likewise.

2012-08-18  Alp Aker  <alp.tekin.aker@gmail.com>

        * nsfont.m (ns_ascii_average_width): Ensure the string
        ascii_printable is initialized with a null-terminated character
        array.  Otherwise, it can contain undesired extra characters.

2012-08-18  Paul Eggert  <eggert@cs.ucla.edu>

        port new setting code to Sun C 5.8 2005/10/13
        * chartab.c, lisp.h (char_table_set, char_table_set_range):
        Return void, not Lisp_Object.  Otherwise, the compiler
        complains about (A?B:C) where B is void and C is Lisp_Object
        when compiling CHAR_TABLE_SET, due to the recent change to
        the API of sub_char_table_set_contents.

2012-08-18  Chong Yidong  <cyd@gnu.org>

        * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
        for the string case (Bug#3874).

2012-08-18  Paul Eggert  <eggert@cs.ucla.edu>

        * buffer.h (BSET): Remove (Bug#12215).
        Replace all uses with calls to new setter functions.

        are compiled into code.
        (pset_buffer, pset_command, pset_decode_coding_system)

        (pset_plist, pset_sentinel, pset_status, pset_tty_name)
        (pset_type, pset_write_queue): New setter functions.

        * window.h (WSET): Remove (Bug#12215).
        Replace all uses with calls to new setter functions.
        Use INLINE_HEADER_BEGIN, INLINE_HEADER_END.
        (WINDOW_INLINE): New macro.

        types, since we want the ASCII interpretation here, not the
        interpretation suitable for whatever happens to be the current locale.

        Use bool, not int, for Lisp booleans.
        This is more natural, and on my platform (GCC 4.7.1 x86-64) it

        * alloc.c (record_xmalloc): New function.
        * lisp.h (record_xmalloc): New decl.
        (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
        more like a function.  This is because the pointer cast is not
        needed.  All uses changed.
        * print.c (print_string, print_error_message): Avoid length recalc.

        Improve fix for macroexp crash with debugging (Bug#12118).
        * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
        ARRAY_MARK_FLAG when checking subscripts, because ASET is
        not supposed to be invoked from the garbage collector.
        See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
        (gc_aset): New function, which is like ASET but can be
        used in the garbage collector.
        (set_hash_key, set_hash_value, set_hash_next, set_hash_hash)
        (set_hash_index): Use it instead of ASET.

        (map_w32_filename): Improve commentary.  Simplify switch.
        (SYMBOLIC_LINK_FLAG_DIRECTORY): Define if not defined in system
        headers (most versions of MinGW w32api don't).

        in the argument file name.
        (sys_access): Call unc_volume_file_attributes only if
        GetFileAttributes fails with network-related error codes.
        (sys_rename): Diagnose renaming of a symlink when the user doesn't
        have the required privileges.
        (get_file_security_desc_by_name): Rename from
        get_file_security_desc.
        (stat_worker): New function, with most of the guts of 'stat', and
        with addition of handling of symlinks and support for 'lstat'.
        If possible, get file's attributes and security information by
        handle, not by name.  Produce S_IFLNK bit for symlinks, when
        called from 'lstat'.
        (stat, lstat): New functions, call 'stat_worker'.
        (symlink, readlink, careadlinkat): Rewritten to create and resolve
        symlinks when the underlying filesystem supports them.

        "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
        (ARRAY_MARK_FLAG): Now a macro as well as a constant,
        since it's used in non-static inline functions now.

        * xfaces.c (face_at_buffer_position, face_for_overlay_string):
        Don't assume buffer size fits in 'int'.  Remove unused local.

        (INLINE_HEADER_END): New macros.
        * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

2012-08-01  Paul Eggert  <eggert@cs.ucla.edu>

        Use "ASET (a, i, v)" rather than "AREF (a, i) = v".

        * regex.c (MAX_BUF_SIZE): Remove some incorrect and
        long-ago-commented-out code that talks about "WIN32".
        * w32heap.h (OS_WINDOWS_95): Rename from OS_WIN95.
        All uses changed.

2012-07-28  Paul Eggert  <eggert@cs.ucla.edu>

        Use Gnulib stdalign module (Bug#9772, Bug#9960).
        * alloc.c (XMALLOC_BASE_ALIGNMENT, GC_POINTER_ALIGNMENT, pure_alloc):
        Simplify by using alignof.
        (pure_alloc) [! USE_LSB_TAG]: Don't over-align EMACS_INT values.

        2012-07-04 changes to pseudovector representation.
        Problem reported by Eli Zaretskii in <http://bugs.gnu.org/12036#30>.

        * alloc.c (listn): Fix the order the arguments are consed onto the
        list.

        * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
        enumeration constants, as PURE and HEAP are too general, and clash
        with other headers and sources, such as gmalloc.c and the
        MS-Windows system headers.  All users changed.

2012-07-27  Dmitry Antipov  <dmantipov@yandex.ru>

        * w32fns.c (syms_of_w32fns): Add missing parenthesis.

2012-07-27  Paul Eggert  <eggert@cs.ucla.edu>

        Improve GDB symbol export (Bug#12036).
        * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
        arms of an 'if', not using conditional expressions; otherwise GDB
        complains about the types in the unevaluated arm when the argument
        is an integer literal.
        (xgetint): Simplify expression.
        * alloc.c (gdb_make_enums_visible): New constant.  This ports to

        Zaretskii in <http://bugs.gnu.org/12036#13>.
        * lisp.h (PUBLISH_TO_GDB): Remove.  All uses removed.  No longer
        needed now that we have gdb_make_enums_visible.
        (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
        (enum enum_USE_LSB_TAG):
        New enum types, packaging up enums that need to be exported to GDB.

2012-07-27  Dmitry Antipov  <dmantipov@yandex.ru>

        Utility function to make a list from specified amount of objects.
        * lisp.h (enum constype): New datatype.
        (listn): New prototype.
        * alloc.c (listn): New function.
        (Fmemory_use_count, syms_of_alloc): Use it.
        * buffer.c (syms_of_buffer): Likewise.
        * callint.c (syms_of_callint): Likewise.
        * charset.c (define_charset_internal): Likewise.

        (PVEC_EXCURSION): New pseudovector type.
        (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
        to deal with it.  Adjust comments.
        (init_marker, attach_marker): New prototype.
        (unchain_marker): Adjust prototype.
        * marker.c (attach_marker): Change to global.
        (init_marker): New function.
        * alloc.c (Fmake_marker, build_marker): Use it.
        (build_marker): More easserts.
        (mark_object): Handle struct Lisp_Excursion.
        * editfns.c (save_excursion_save, save_excursion_restore):

2012-07-26  Paul Eggert  <eggert@cs.ucla.edu>

        Fix export of symbols to GDB (Bug#12036).
        * alloc.c (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL)
        (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
        emacs.c, as this is a more-suitable home.  Had this been done earlier
        the fix for 12036 would have avoided some of the problems noted in
        <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
        would have been more obvious.
        * emacs.c: Do not include <verify.h>; no longer needed.
        (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
        (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
        (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):

        * lisp.h (PUBLISH_TO_GDB): New macro.
        (GCTYPEBITS, USE_LSB_TAG, CHECK_LISP_OBJECT_TYPE, enum pvec_type)
        (DATA_SEG_BITS): Use it.
        (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
        (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
        * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
        not be usable in #if.  This simplifies things.

2012-07-26  Juanma Barranquero  <lekktu@gmail.com>

        * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.

2012-07-26  Paul Eggert  <eggert@cs.ucla.edu>

        Simplify export of symbols to GDB (Bug#12036).
        * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
        $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
        (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
        Adjust to changes in lisp.h and emacs.c, by using
        CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
        of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
        INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
        gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
        instead of gdb_valbits.
        (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
        PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
        instead of gdb_array_mark_flag.
        (xboolvector): Get size from $->size, not $->header.size.
        Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
        (xreload, hook-run, hookpost-run): Remove.
        * emacs.c: Include <verify.h>.
        (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
        (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
        Remove.
        (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
        (gdb_USE_LSB_TAG): New enum constants.
        (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
        Also define these as enum constants, so they're visible to GDB.
        (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
        (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
        as constants, so they're visible to GDB.
        * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
        (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
        Now enum constants, not macros, so they're visible to GDB.
        (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
        more convenient now.  All uses changed.
        (VALMASK) [USE_LSB_TAG]: Also define in this case.
        * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.

2012-07-26  Dmitry Antipov  <dmantipov@yandex.ru>

        Explicitly free restriction data that are not needed anymore.
        * editfns.c (save_restriction_restore): Free restriction data.

        add argument, tune behavior, and adjust all callers.

2012-07-25  Paul Eggert  <eggert@cs.ucla.edu>

        Use typedef for EMACS_INT, EMACS_UINT.
        * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
        than macros.  This simplifies debugging in the usual case, since
        it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
        and it allows expressions involving EMACS_INT casts.
        * .gdbinit (xreload): Simplify by using EMACS_INT cast.

2012-07-25  Jan Djärv  <jan.h.d@swipnet.se>

        * nsterm.m (ns_read_socket): Return early if there is a modal

        that FOCUS-FRAME can be omitted.

2012-07-25  Dmitry Antipov  <dmantipov@yandex.ru>

        Adjust buffer text indirection counters at the end of Fkill_buffer.
        * buffer.c (Fkill_buffer): Adjust indirection counters when the
        buffer is definitely dead.  This should really fix an issue reported
        by Christoph Scholtes again.  (Bug#12007).
        (init_buffer_once): Initialize indirection counters of
        buffer_defaults and buffer_local_symbols (for sanity and safety).

2012-07-24  Eli Zaretskii  <eliz@gnu.org>

        * xdisp.c (init_iterator): Don't compute dimensions of truncation

        * print.c (print_object): Don't crash when a frame's name is nil
        or invalid.  (Bug#12025)

        * window.c (decode_any_window): Disable CHECK_LIVE_FRAME test, as
        it signals an error when a tooltip frame is being created.

2012-07-23  Dmitry Antipov  <dmantipov@yandex.ru>

        Cleanup miscellaneous objects allocation and initialization.
        * alloc.c (allocate_misc): Change to static.  Add argument to
        specify the subtype.  Adjust comment and users.
        (build_overlay): New function.
        * buffer.c (copy_overlays, Fmake_overlay): Use it.
        * lisp.h (struct Lisp_Overlay): Remove obsolete comment.
        (allocate_misc): Remove prototype.
        (build_overlay): Add prototype.

2012-07-23  Dmitry Antipov  <dmantipov@yandex.ru>

        Swap buffer text indirection counters in Fbuffer_swap_text.
        * buffer.c (Fbuffer_swap_text): Swap indirections too.
        This avoids crash reported by Christoph Scholtes at
        http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.

2012-07-22  Jan Djärv  <jan.h.d@swipnet.se>

        * nsmenu.m (Popdown_data): New struct.
        (pop_down_menu): p->pointer is Popdown_data.  Release the pool and
        free Popdown_data.
        (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.
        (initWithContentRect): Make imgView and contentView non-static
        and autorelease them.  Also autorelease img and matrix (Bug#12005).
        (dealloc): Remove (Bug#12005).

2012-07-22  Dmitry Antipov  <dmantipov@yandex.ru>

        Adjust consing_since_gc when objects are explicitly freed.

        (free_cons, free_misc): Subtract object size from consing_since_gc.

2012-07-22  Dmitry Antipov  <dmantipov@yandex.ru>

        Simplify and cleanup markers positioning code.
        * marker.c (attach_marker): More useful eassert.
        (live_buffer, set_marker_internal): New function.
        (Fset_marker, set_marker_restricted): Use set_marker_internal.

2012-07-22  Paul Eggert  <eggert@cs.ucla.edu>

        * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
        as it's limited by the amount of memory, not by INT_MAX.

2012-07-21  Eli Zaretskii  <eliz@gnu.org>

        * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
        in special-event-map.  See the discussion at

        for the reasons.

        * w32menu.c (add_menu_item): Cast to ULONG_PTR when assigning

        Make maybe_gc inline.
        Verify that inlining is always possible (GCC 4.7.1, -O3 -Winline).
        * lisp.h (consing_since_gc, gc_relative_threshold)
        (memory_full_cons_threshold): Revert declaration.

        * s/aix4-2.h (unix): Remove; no longer needed.

        EMACS_TIME simplification (Bug#11875).
        This replaces macros (which typically do not work in GDB)
        with functions, typedefs and enums, making the code easier to debug.
        The functional style also makes code easier to read and maintain.
        * systime.h: Include <sys/time.h> on all hosts, not just if
        WINDOWSNT, since 'struct timeval' is needed in general.
        (EMACS_TIME): Now a typedef, not a macro.
        (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): Now constants,

        (make_emacs_time): New function.
        (EMACS_SECS_ADDR, EMACS_SET_INVALID_TIME, EMACS_GET_TIME)
        (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
        not functions.  All uses rewritten to use the following, respectively:
        (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
        (add_emacs_time, sub_emacs_time): New functions.
        * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.

        * lread.c (openp):
        * nsmenu.m (ns_update_menubar):
        * regex.c (regerror):
        Prefer memcpy to strncpy and strncat when either will do.
        * fileio.c (Fsubstitute_in_file_name):
        * keyboard.c (MULTI_LETTER_MOD, parse_modifiers_uncached)
        (menu_separator_name_p):
        * nsmenu.m (ns_update_menubar):
        Prefer memcmp to strncmp when either will do.
        * nsterm.m: Include <ftoastr.h>.
        (ns_get_color):
        * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
        Prefer snprintf to strncpy.

        * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
        * nsterm.m (ns_term_init):
        Avoid the need for strncpy, by using build_string or
        make_unibyte_string directly.  Use dtoastr, not snprintf.
        * process.c (Fmake_network_process): Diagnose service names that
        are too long, rather than silently truncating them or creating
        non-null-terminated names.
        (Fnetwork_interface_info): Likewise, for interface names.
        * sysdep.c (system_process_attributes) [GNU_LINUX]:
        Prefer sprintf to strncat.
        * xdisp.c (debug_method_add) [GLYPH_DEBUG]:
        Prefer vsnprintf to vsprintf + strncpy.

2012-07-10  Glenn Morris  <rgm@gnu.org>

        * dispnew.c (PENDING_OUTPUT_COUNT) [!__GNU_LIBRARY__]:
        Clarify fallback case.

2012-07-10  Dmitry Antipov  <dmantipov@yandex.ru>

        (build_pure_c_string): New function, defined as static inline.  This
        provides a better opportunity to optimize away calls to strlen when
        the function is called with compile-time constant argument.
        * alloc.c (make_pure_c_string): Fix comment.  Change to add nchars
        argument, adjust users accordingly.  Use build_pure_c_string where
        appropriate.
        * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
        * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,

        srclen argument and return the length of result.  Adjust users
        accordingly.

        Stop ns builds setting the EMACSLOADPATH environment variable.
        * nsterm.m (ns_load_path): Rename from ns_init_paths.
        Now it does not set EMACSLOADPATH, just returns the load-path string.

        (init_lread) [HAVE_NS]: Use ns_load_path.

        (ns_init_paths): Do not set EMACSPATH.

        Add GCC-style 'const' attribute to functions that can use it.
        * character.h (char_resolve_modifier_mask):
        * keyboard.h (make_ctrl_char):

        Minor improvements to make_formatted_string.
        * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
        where int is good enough, as vsprintf returns an int.

2012-07-09  Dmitry Antipov  <dmantipov@yandex.ru>

        Move marker debugging code under MARKER_DEBUG.
        * marker.c (MARKER_DEBUG): Move marker debugging code under
        #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
        for bootstrap with --enable-checking (~3x slowdown reported
        by Juanma Barranquero <lekktu@gmail.com>).
        (verify_bytepos): Move under #ifdef MARKER_DEBUG.

2012-07-08  Paul Eggert  <eggert@cs.ucla.edu>

        * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
        See <http://bugs.gnu.org/11825#29>.

2012-07-08  Eli Zaretskii  <eliz@gnu.org>

        * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
        has no font, use the frame's font.  (Bug#11813)
        (display_line): Add commentary about displaying truncation glyphs
        on GUI frames.
        (produce_special_glyphs): Move here from term.c.

        * term.c (produce_special_glyphs): Move to xdisp.c.

        * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
        section.

        of FRAME_FONT.

        * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.

        * lisp.h: Remove empty conditional.

2012-07-07  Paul Eggert  <eggert@cs.ucla.edu>

        * lread.c (load_path_check): Now static.

        Fix some minor --with-ns problems found by static checking.
        * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
        (x_set_font) [!HAVE_X_WINDOWS]:
        * image.c (xpm_load_image) [HAVE_NS]:
        (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
        (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
        Remove unused local.
        (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
        (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
        * image.c (x_create_bitmap_from_file) [HAVE_NS]:

        * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
        * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
        Fix pointer signedness problem.
        * xfaces.c (FRAME_X_FONT_TABLE):
        * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.

2012-07-07  Glenn Morris  <rgm@gnu.org>

        * lread.c (load_path_check): New function, split from init_lread.
        (init_lread): Reorganize.  Motivation:
        If EMACSLOADPATH is set, check/warn about that rather than the
        defaults, which we are not going to use.  Hence we can remove
        the turn_off_warning and WINDOWSNT || HAVE_NS tests.
        Don't warn if site-lisp directories are missing.
        If not installed, start from a blank load-path, since
        PATH_LOADSEARCH refers to the eventual installation directories.

2012-07-07  Eli Zaretskii  <eliz@gnu.org>

        Support truncation and continuation glyphs on GUI frames, when
        fringes are disabled.  (Bug#11832)
        * xdisp.c (init_iterator): Get dimensions of truncation and
        continuation glyphs even if on GUI frames.
        Adjust it->last_visible_x on GUI frames when the left or right fringes,
        or both, are absent.
        (start_display, move_it_in_display_line_to): Handle the case of a
        GUI frame without a fringe to display continuation or truncation
        glyphs.
        (insert_left_trunc_glyphs): Support GUI frames: make sure
        truncation glyphs overwrite enough glyphs from the current line to
        have sufficient space in pixels.
        (display_line): Support truncation and continuation glyphs on GUI
        frames.  If some spare pixels are left on the line after inserting
        the truncation glyphs, fill that space with a stretch glyph of a
        suitably computed width.

        * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
        produce_glyphs, to support GUI sessions.

2012-07-07  Paul Eggert  <eggert@cs.ucla.edu>

        * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).

        * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).

        Do not require float-time's arg to fit in time_t (Bug#11825).
        This works better on hosts where time_t is unsigned, and where
        float-time is applied to the (negative) difference between two times.
        * editfns.c (decode_time_components): Last arg is now double *,
        not int *, and means to store all the result as a double, without
        worrying about whether the seconds part fits in time_t.
        All callers changed.
        (lisp_time_argument): Remove last int * arg, as it's no longer needed.
        All callers changed.
        (Ffloat_time): Do not fail merely because the specified time falls
        outside of time_t range.

2012-07-07  Glenn Morris  <rgm@gnu.org>

        * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

2012-07-07  Juanma Barranquero  <lekktu@gmail.com>

        * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
        Update dependencies.

        * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.

        * xfont.c (compare_font_names): Redo to omit the need for casts.

2012-07-06  Andreas Schwab  <schwab@linux-m68k.org>

        * xfns.c (Fx_change_window_property): Doc fix.
        * w32fns.c (Fx_change_window_property): Doc fix.

        * w32fns.c (Fx_window_property): Accept the same arguments as the
        X Windows version.  Doc fix.
        * xfns.c (Fx_window_property): Doc fix.  (Bug#11870)

2012-07-06  Juanma Barranquero  <lekktu@gmail.com>
            Eli Zaretskii  <eliz@gnu.org>

        * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
        Windows-specific code from nt/config.nt moved here.
        Obsolete settings removed.

2012-07-06  Paul Eggert  <eggert@cs.ucla.edu>

        * process.c: Avoid unnecessary calls to gettime.
        (wait_reading_process_output): Don't get the time of day
        when gobbling data immediately and not waiting, as there's no need
        for it in that case.  This removes a FIXME.

2012-07-06  Jan Djärv  <jan.h.d@swipnet.se>

        * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
        is defined (Bug#11768).

2012-07-06  Dmitry Antipov  <dmantipov@yandex.ru>

        Fix marker debugging code.
        * marker.c (byte_char_debug_check): Do not perform the check
        if buffer is not multibyte.
        (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
        Call byte_char_debug_check with correct arguments.

2012-07-06  Dmitry Antipov  <dmantipov@yandex.ru>

        Compile marker debugging code only if ENABLE_CHECKING is defined.
        * marker.c (byte_char_debug_check, count_markers):
        Use only if ENABLE_CHECKING is defined.
        (byte_debug_flag): Remove.
        (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
        Always call byte_char_debug_check if ENABLE_CHECKING is defined.

2012-07-06  Dmitry Antipov  <dmantipov@yandex.ru>

        Avoid code repetition in marker-related functions.

        (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
        (save_restriction_save): Use build_marker.
        * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
        * window.c (save_window_save): Likewise.

2012-07-06  Dmitry Antipov  <dmantipov@yandex.ru>

        * minibuf.c (get_minibuffer): Fix comment.

2012-07-06  Paul Eggert  <eggert@cs.ucla.edu>

        Port to OpenBSD 5.1 amd64.
        * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
        This is needed for OpenBSD, and should be harmless on all BSD systems.
        Also, include <sys/sysctl.h>, as it should be available on all
        BSD_SYSTEM hosts given that we're already calling sysctl in that case.
        (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
        use p_pid member, not kp_proc.pid.

2012-07-06  Glenn Morris  <rgm@gnu.org>

        * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.

        * xterm.c:
        Omit needless casts involving void * pointers and allocation.
        Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
        as the former is more robust if P's type is changed.
        Prefer xzalloc to xmalloc + memset 0.
        Simplify malloc-or-realloc to realloc.
        Don't worry about xmalloc returning a null pointer.
        Prefer xstrdup to xmalloc + strcpy.

        growing it.
        * keyboard.c (apply_modifiers_uncached): Prefer local array to
        alloca of a constant.

        * xdisp.c (display_line): Fix horizontal pixel coordinates when
        hscroll is larger than the line width.  Fixes long and futile
        looping inside extend_face_to_end_of_line (on a TTY) producing
        glyphs that are not needed and thrown away.

2012-07-05  Dmitry Antipov  <dmantipov@yandex.ru>

        * marker.c (set_marker_restricted_both): Simplify by using

        (update_theme_scrollbar_width, xg_create_scroll_bar):
        Use gtk_scrollbar_new (Bug#11768).

        (is_box_type): New function (Bug#11768).
        (xg_tool_item_stale_p): Call is_box_type.
        (xg_initialize): Get settings by calling gtk_settings_get_for_screen
        with default display (Bug#11768).

        * xdisp.c (window_hscroll_limited): New function.
        (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
        coordinates when window's hscroll is set to insanely large

2012-07-04  Paul Eggert  <eggert@cs.ucla.edu>

        * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
        This should be fixed in a better way; see Eli Zaretskii in
        <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
        (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.

        * fileio.c (time_error_value): Rename from special_mtime.
        The old name's problems were noted by Eli Zaretskii in
        <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.

        * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
        This variable's comment says Emacs needs at least one GDB-visible
        symbol of type enum pvec_type, to work around GDB problems.
        The symbol's value doesn't matter.

        * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
        that causes compilation to fail on pre-C99 compilers.

2012-07-04  Juanma Barranquero  <lekktu@gmail.com>

        (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
        (sweep_vectors): Use it.  Use local var `total_bytes' instead of
        abusing vector->header.next.nbytes.
        (live_vector_p): Use PVEC_TYPE.
        (mark_object): Adapt code to extract pvectype.  Use switch.

2012-07-04  Paul Eggert  <eggert@cs.ucla.edu>

        * doprnt.c (doprnt): Don't assume string length fits in 'int'.
        Tighten new eassert a bit.

2012-07-04  Dmitry Antipov  <dmantipov@yandex.ru>

        Fix compilation with --enable-gcc-warnings and -O1
        optimization level.
        * doprnt.c (doprnt): Change type of tem to int, initialize
        to avoid compiler warning.  Add eassert.
        * search.c (simple_search): Initialize match_byte to avoid
        compiler warning.  Add eassert.

2012-07-04  Paul Eggert  <eggert@cs.ucla.edu>

        Avoid weird behavior with large horizontal scrolls.
        Without this change, for example, large hscroll values would
        mess up Emacs's display on Fedora 15 x86, presumably due to
        overflows in int calculations in the display code.
        Also, if buffers had long lines, Emacs would freeze.
        * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
        (set_window_hscroll): New function, containing the old guts of
        Fset_window_hscroll.  Return the clipped value.
        (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
        This avoids the need to check against PTRDIFF_MAX.

        * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.

2012-07-04  Dmitry Antipov  <dmantipov@yandex.ru>

        * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.

2012-07-04  Paul Eggert  <eggert@cs.ucla.edu>

        * regex.c: Suppress GCC warning on RHEL 6.  (Bug#11207)
        Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
        since GCC 4.4.6 issues a bogus warning for them.

        Fix bugs in file timestamp newness comparisons.
        * fileio.c (Ffile_newer_than_file_p):
        * lread.c (Fload): Use full timestamp resolution of files,
        not just the 1-second resolution, so that files that are only
        slightly newer still count as newer.
        * fileio.c (Ffile_newer_than_file_p): Don't assume file
        timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.

2012-07-03  Paul Eggert  <eggert@cs.ucla.edu>

        * fileio.c: Improve handling of file time marker.  (Bug#11852)
        (special_mtime): New function.
        (Finsert_file_contents, Fverify_visited_file_modtime):
        Use it to set special mtime values consistently.

2012-07-03  Andreas Schwab  <schwab@linux-m68k.org>

        * fileio.c (Finsert_file_contents): Properly handle st_mtime
        marker for non-existing file.  (Bug#11852)

2012-07-03  Glenn Morris  <rgm@gnu.org>

        * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
        and did not make it into globals.h).

2012-07-03  Tom Tromey  <tromey@redhat.com>

        * window.c (Fset_window_margins, Fset_window_fringes)
        (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.

        * lisp.h (Frandom): Make it visible to C.
        * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
        buffer for invisible buffers.  (Bug#1229)

2012-07-03  Dmitry Antipov  <dmantipov@yandex.ru>

        Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
        values which aren't power of 2.
        * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
        Verify its value and the value of VECTOR_BLOCK_SIZE.  Adjust users
        accordingly.

2012-07-03  Stefan Monnier  <monnier@iro.umontreal.ca>

        * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.

        * alloc.c (mark_object): Revert part of last patch to use `switch'.

2012-07-03  Dmitry Antipov  <dmantipov@yandex.ru>

        * alloc.c (allocate_vector_block): Remove redundant
        calls to mallopt if DOUG_LEA_MALLOC is defined.
        (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
        avoid calls to mallopt if zero_vector is returned.

2012-07-03  Dmitry Antipov  <dmantipov@yandex.ru>

        Cleanup basic buffer management.
        * buffer.h (struct buffer): Change layout to use generic vector
        marking code.  Fix some comments.  Change type of 'clip_changed'
        to bitfield.  Remove unused #ifndef old.
        (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
        (GET_OVERLAYS_AT): Fix indentation.
        (for_each_per_buffer_object_at): New macro.

        and related comments.

2012-07-02  Paul Eggert  <eggert@cs.ucla.edu>

        * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
        wrapper that is not needed because the wrapped code is a no-op (zero
        machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
        This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.

2012-07-02  Dmitry Antipov  <dmantipov@yandex.ru>

        * alloc.c (mark_buffer): Simplify.  Remove prototype.
        (mark_object): Add comment.  Reorganize marking of vector-like
        objects.  Use CHECK_LIVE for all vector-like objects except buffers
        and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
        Avoid redundant calls to mark_vectorlike for bool vectors.

2012-06-30  Glenn Morris  <rgm@gnu.org>

        * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.

        * epaths.in (PATH_SITELOADSEARCH): New.
        * lread.c (init_lread): Use PATH_SITELOADSEARCH.
        This is rather than relying on --enable-locallisppath elements
        having "site-lisp" in their names.  (Bug#10208#25, 11658)

2012-06-30  Eli Zaretskii  <eliz@gnu.org>

        * w32proc.c (sys_select): Accept and ignore one more argument.

        * w32.c (emacs_gnutls_pull): Call select with one more argument.

        * sysselect.h [DOS_NT]: Don't include sys/select.h.
        (pselect) [!MS_DOS]: Redirect to sys_select.

        * sysdep.c: Don't include dos.h and dosfns.h.

        * process.c (sys_select):
        * msdos.c (sys_select): Accept one more argument and ignore it.

        * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
        adapt data types and code to that.

        * dosfns.c:
        * msdos.c (gettime, settime): Define away the prototypes in dos.h,
        which clashes with the gnulib function of the same name.

2012-06-30  Andreas Schwab  <schwab@linux-m68k.org>

        * font.c (font_style_to_value, font_style_symbolic)

        * xdisp.c (try_window_id): Undo last change.

        * w32.c (getwd): Adjust commentary about startup_dir.
        (init_environment): Always call sys_access, even in non-MSVC
        builds.  Don't chdir to the directory of the Emacs executable.
        This undoes code from 1997 which was justified by the need to
        "avoid conflicts when removing and renaming directories".  But its
        downside was that every relative file name was being interpreted
        relative to the directory of the Emacs executable, which can never
        be TRT.  In particular, it broke sys_access when called with
        relative file names.
        (sys_access): Map GetLastError to errno.

2012-06-29  Dmitry Antipov  <dmantipov@yandex.ru>

        Adjust comment.
        * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
        to ptrdiff_t.

        'last_modified' and 'last_overlay_modified' to EMACS_INT.
        Adjust users accordingly.
        * xdisp.c (try_cursor_movement): Replace type check with eassert.
        * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
        from EMACS_INT to ptrdiff_t.
        (make_window): Omit redundant initialization.

2012-06-28  Juanma Barranquero  <lekktu@gmail.com>

        Use sprintf return value instead of invoking strlen on result.
        In the old days this wasn't portable, since some sprintf
        implementations returned char *.  But they died out years ago and
        Emacs already assumes sprintf returns int.
        Similarly for float_to_string.
        This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

        Use sprintf or float_to_string result to avoid need to call strlen.
        * data.c (Fnumber_to_string):

        * lisp.h, print.c (float_to_string): Now returns int length.
        * term.c (produce_glyphless_glyph):
        Use sprintf result rather than recomputing it.

2012-06-22  Paul Eggert  <eggert@cs.ucla.edu>

        Support higher-resolution time stamps (Bug#9000).
        The time stamps are only nanosecond-resolution at the C level,
        since that's the best that any real-world system supports now.
        But they are picosecond-resolution at the Lisp level, as that's
        easy, and leaves room for future OS improvements.

        * Makefile.in (LIB_CLOCK_GETTIME): New macro.
        (LIBES): Use it.

        * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
        Don't get current time unless it's needed.

        * atimer.c: Include <sys/time.h> unconditionally, since gnulib
        now provides it if it's absent.
        (start_atimer): Port to higher-res time stamps.
        Check for time stamp overflow.  Don't get current time more
        often than is needed.

        * buffer.h (struct buffer): Buffer modtime now has high resolution.
        Include systime.h, not time.h.
        (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.

        * dired.c: Include stat-time.h.
        (Ffile-attributes): File times now have higher resolution.

        * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
        (struct image): Timestamp now has higher resolution.

        * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
        has at least microseconds now.  All uses removed.
        (update_frame, update_single_window, update_window, update_frame_1)
        (Fsleep_for, sit_for): Port to higher-resolution time stamps.
        (duration_to_sec_usec): Remove; no longer needed.

        * editfns.c (time_overflow): Now extern.
        (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
        (float-time, Fformat_time_string, Fcurrent_time_string)
        (Fcurrent_time_zone): Accept and generate higher-resolution
        time stamps.
        (make_time_tail, make_lisp_time, dissassemble_lisp_time)
        (decode_time_components, lisp_seconds_argument): New functions.
        (make_time): Now static.
        (lisp_time_argument): Now returns EMACS_TIME.  New arg ppsec.
        Report an error if the time is invalid, rather than having the caller
        do that.

        * fileio.c: Include <stat-time.h>
        (Fcopy_file): Copy higher-resolution time stamps.
        Prefer to set the time stamp via a file descriptor if that works.
        (Fset_file_times, Finsert_file_contents, Fwrite_region)
        (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
        (Fvisited_file_modtime, Fset_visited_file_modtime):
        Support higher-resolution time stamps.

        * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.

        * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.

        * image.c (prepare_image_for_display, clear_image_cache)
        (lookup_image): Port to higer-resolution time stamps.

        * keyboard.c (start_polling, bind_polling_period):
        Check for time stamp overflow.
        (read_char, kbd_buffer_get_event, timer_start_idle)
        (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
        (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
        Port to higher-resolution time stamps.  Do not assume time_t is signed.
        (decode_timer): New function.  Timers are now vectors of length 9,
        not 8, to accommodate the picosecond component.
        (timer_check_2): Use it.

        * nsterm.m (select_timeout, timeval_subtract): Remove.
        (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
        as they're a bit more accurate and handle overflow better.
        (ns_select): Change prototype to be compatible with pselect.
        (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
        * nsterm.h (ns_select): Adjust prototype.

        * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
        us-resolution time stamps.
        (sys_select): Use the new EMACS_TIME_SIGN macro instead.

        * lread.c (read_filtered_event): Port to ns-resolution time stamps.

        * lisp.h (time_overflow): New decl.
        (wait_reading_process_output): First arg is now intmax_t, not int,
        to accommodate larger waits.

        * process.h (struct Lisp_Process.read_output_delay):
        Now counts nanoseconds, not microseconds.
        * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
        EMACS_HAS_USECS.
        (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
        (wait_reading_process_output):
        Port to ns-resolution time stamps.
        (Faccept_process_output, wait_reading_process_output):
        Check for time stamp overflow.  Do not assume time_t is signed.
        (select_wrapper): Remove; we now use pselect.
        (Fprocess_attributes): Now generates ns-resolution time stamps.

        * sysdep.c: Include utimens.h.  Don't include utime.h
        or worry about struct utimbuf; gnulib does that for us now.
        (gettimeofday): Remove; gnulib provides a substitute.
        (make_timeval): New function.
        (set_file_times): Now sets ns-resolution time stamps.
        New arg FD; all uses changed.
        (time_from_jiffies, ltime_from_jiffies, get_up_time)
        (system_process_attributes):
        Now returns ns-resolution time stamp.  All uses changed.
        Check for time stamp overflow.

        * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
        provides a substitute now.

        * systime.h: Include timespec.h rather than sys/time.h and time.h,
        since it guarantees struct timespec.
        (EMACS_TIME): Now struct timespec, so that we can support
        ns-resolution time stamps.
        (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
        (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
        (EMACS_USECS): Remove.
        (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
        so multiply the arg by 1000 before storing it.
        (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
        New macros.

        (make_timeval, make_lisp_time, decode_time_components): New decls.
        (EMACS_TIME_CMP): Remove; no longer used.  Plus, it was buggy, in
        that it mishandled time_t overflow.  You can't compare by subtracting!
        (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
        (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.

        * term.c: Include <sys/time.h>.
        (timeval_to_Time): New function, for proper overflow wraparound.
        (term_mouse_position, term_mouse_click): Use it.

        * undo.c (record_first_change): Support higher-resolution time stamps
        in the undo buffer.
        (Fprimitive_undo): Use them when restoring time stamps.

        * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
        (w32_get_internal_run_time):
        Port to higher-resolution Emacs time stamps.
        (ltime): Now accepts single 64-bit integer, as that's more convenient
        for callers.

        * xdisp.c (start_hourglass): Port to ns-resolution time stamps.

        * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
        for compatibility with pselect.  Support ns-resolution time stamps.

        * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.

        * xselect.c (wait_for_property_change, x_get_foreign_selection):
        Check for time stamp overflow, and support ns-resolution time stamps.

        * xterm.c: Don't include sys/time.h; gnulib does that for us now.
        Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
        (timeval_subtract): Remove; no longer needed.
        (XTflash, XTring_bell, x_wait_for_event):
        Port to ns-resolution time stamps.  Don't assume time_t is signed.

2012-06-22  Eli Zaretskii  <eliz@gnu.org>

        with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
        aborts in staticpro during startup.  (Without -DBYTE_CODE_METER,
        staticidx goes up to 1597 out of 1600 = 0x640.)

2012-06-20  Paul Eggert  <eggert@cs.ucla.edu>

        * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.

        * print.c, syntax.c, window.c, xmenu.c, xselect.c: Replace direct
        access to `contents' member of Lisp_Vector objects with AREF and ASET
        where appropriate.

2012-06-19  Chong Yidong  <cyd@gnu.org>

        * frame.c (delete_frame): When selecting a frame on a different
        text terminal, do not alter the terminal's top-frame.

        * xdisp.c (format_mode_line_unwind_data): Record the target
        frame's selected window and its terminal's top-frame.

        Callers changed.
        (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,

        (prepare_menu_bars): Likewise.

        * term.c (Ftty_top_frame): New function.

2012-06-18  Paul Eggert  <eggert@cs.ucla.edu>

        Port byte-code-meter to modern targets.
        * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume

        This removes the need for CHECK.
        (CHECK): Remove.  Its comments about always evaluating its
        argument were confusing, as 'eassert' typically does not evaluate
        its argument.

        * coding.c (produce_chars): Use ptrdiff_t, not int.

        * xterm.c (x_draw_underwave): Check for integer overflow.

2012-06-16  Eli Zaretskii  <eliz@gnu.org>

        * xdisp.c (set_cursor_from_row): Don't dereference glyphs_end.
        If all the glyphs of the glyph row came from strings, and we have no
        cursor positioning clues, put the cursor on the first glyph of the
        row.
        (handle_face_prop): Use chunk-relative overlay string index when
        indexing into it->string_overlays array.  (Bug#11653)

        (LISP_INT_TAG, case_Lisp_Int, LISP_STRING_TAG, LISP_INT_TAG_P)

        * data.c (Fmake_variable_buffer_local, Fmake_local_variable):

        USE_LSB_TAG now is always defined to be either 0 or 1.
        All uses changed.
        (union Lisp_Object): Don't worry about WORDS_BIGENDIAN; the
        code works fine either way, and efficiency is not a concern here,
        as the union type is for debugging, not for production.
        (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
        Use an inline function on all platforms when using the union type,
        since this is simpler and 'static inline' can be used portably
        within Emacs now.

        Without this change, (let ((§ 1)) (make-variable-buffer-local '§))

        Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
        would mishandle a string argument "Xc" if X was a multibyte
        character of length 2: it would truncate after X's first byte
        rather than including all of X.

2012-06-06  Chong Yidong  <cyd@gnu.org>

2012-06-02  Andreas Schwab  <schwab@linux-m68k.org>

        * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of

        * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.

2012-06-01  Dmitry Antipov  <dmantipov@yandex.ru>

        For a 'struct window', replace some Lisp_Object fields to
        bitfields where appropriate, remove unused fields.
        * window.h (struct window): Remove unused 'last_mark_x' and
        'last_mark_y' fields.  Rename 'mini_p' field to 'mini',
        change its type from Lisp_Object to bitfield.
        Change type of 'force_start', 'optional_new_start',
        'last_had_star', 'update_mode_line' and 'start_at_line_beg'
        fields from Lisp_Object to bitfield.  Adjust users accordingly.

2012-05-31  Paul Eggert  <eggert@cs.ucla.edu>

        Pacify gcc -Wdouble-precision when using Xaw.
        * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
        [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
        Use 'float' consistently, rather than 'float' in most places
        and 'double' in a couple of places.

2012-05-31  Eli Zaretskii  <eliz@gnu.org>

        * xdisp.c (handle_stop): Detect whether we have overlay strings
        loaded by testing it->current.overlay_string_index to be
        non-negative, instead of checking whether n_overlay_strings is
        positive.  (Bug#11587)

2012-05-31  Chong Yidong  <cyd@gnu.org>

        * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).

        * doc.c (Fsubstitute_command_keys): Doc fix.

2012-05-31  Eli Zaretskii  <eliz@gnu.org>

        * search.c (search_buffer): Remove calls to
        r_alloc_inhibit_buffer_relocation, as it is now called by
        maybe_unify_char, which was the cause of relocation of buffer text
        in bug#11519.

2012-05-31  Eli Zaretskii  <eliz@gnu.org>

        * charset.c (maybe_unify_char): Inhibit relocation of buffer text
        for the duration of call to load_charset, to avoid problems with
        callers of maybe_unify_char that access buffer text through C
        pointers.

        * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
        decrement the inhibition flag, instead of just setting or
        resetting it.

2012-05-31  Paul Eggert  <eggert@cs.ucla.edu>

        Remove obsolete '#define static' cruft.
        * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
        This #undef was "temporary" in 2000; it is no longer needed
        now that '#define static' has gone away.
        * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
        (gray_bitmap_bits): Remove; no longer needed.
        All uses replaced with definiens.
        * xterm.c: Include "bitmaps/gray.xbm".

2012-05-30  Paul Eggert  <eggert@cs.ucla.edu>

        Clean up __executable_start, monstartup when --enable-profiling.
        The following changes affect the code only when profiling.
        * dispnew.c (__executable_start): Rename from safe_bcopy.
        Define only on platforms that need it.
        * emacs.c: Include <sys/gmon.h> when profiling.
        (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
        (__executable_start): Remove decl, since lisp.h does it now.
        (safe_bcopy): Remove decl; no longer has that name.
        (main): Coalesce #if into single bit of code, for simplicity.
        Cast pointers to uintptr_t, since standard libraries want integers
        and not pointers.
        * lisp.h (__executable_start): New decl.

2012-05-31  Glenn Morris  <rgm@gnu.org>

        * image.c (Fimagemagick_types): Doc fix.

2012-05-30  Jim Meyering  <meyering@redhat.com>

        * callproc.c (Fcall_process_region): Include directory component
        in mkstemp error message (Bug#11586).

2012-05-30  Paul Eggert  <eggert@cs.ucla.edu>

        * alloc.c, lisp.h (make_pure_vector): Now static.

2012-05-30  Stefan Monnier  <monnier@iro.umontreal.ca>

        * eval.c (Fdefun, Fdefmacro, Vmacro_declaration_function):
        Move to byte-run.el.
        (Fautoload): Do the hash-doc more carefully.
        * data.c (Fdefalias): Purify definition, except for keymaps.
        (Qdefun): Move from eval.c.
        * lisp.h (Qdefun): Remove.
        * lread.c (read1): Tiny simplification.

2012-05-29  Troels Nielsen  <bn.troels@gmail.com>

        Do not create empty overlays with the evaporate property (Bug#9642).
        * buffer.c (Fmove_overlay): Reinstate the earlier fix for
        Bug#9642, but explicitly check that the buffer the overlay would
        be moved to is live and rearrange lines to make sure that errors
        will not put the overlay in an inconsistent state.
        (Fdelete_overlay): Cosmetics.

2012-05-28  Eli Zaretskii  <eliz@gnu.org>

        * w32term.c (my_bring_window_to_top): New function.
        (x_raise_frame): Use handle returned by DeferWindowPos, which
        could be different from the original one.
        Call my_bring_window_to_top instead of my_set_foreground_window.
        (Bug#11513)

        * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
        by calling BringWindowToTop.

        * w32term.h (WM_EMACS_BRINGTOTOP): New message.
        (WM_EMACS_END): Increase by one.

2012-05-28  Paul Eggert  <eggert@cs.ucla.edu>

        * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
        This avoids undefined behavior that might cause the eassert
        to not catch an out-of-range value.

2012-05-28  Juanma Barranquero  <lekktu@gmail.com>

        * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
        Update dependencies.

2012-05-27  Eli Zaretskii  <eliz@gnu.org>

        * bidi.c (bidi_mirror_char): Fix last change.

2012-05-27  Andreas Schwab  <schwab@linux-m68k.org>

        * unexmacosx.c (copy_data_segment): Truncate after 16 characters
        when referring to sectname field in printf format.

2012-05-27  Paul Eggert  <eggert@cs.ucla.edu>

        * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
        Only r_alloc_inhibit_buffer_relocation needed to be added;
        the others were already declared.

        * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
        before checking whether it's out of range.  Put the check inside
        eassert.  See
        <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.

2012-05-27  Ken Brown  <kbrown@cornell.edu>

        * callproc.c (Fcall_process): Restore a line that was accidentally
        commented out in the 2011-02-13 change (bug#11547).

2012-05-27  Eli Zaretskii  <eliz@gnu.org>

        * lisp.h [REL_ALLOC]: Add prototypes for external functions
        defined on ralloc.c.

        * buffer.c [REL_ALLOC]: Remove prototypes of
        r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
        they are now on lisp.h.

        * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.

        * search.c (search_buffer): Use it to inhibit relocation of buffer
        text while re_search_2 is doing its job, because re_search_2 is
        passed C pointers to buffer text.  (Bug#11519)

        * msdos.c (internal_terminal_init) <Vwindow_system_version>:
        Update value to 24.

        * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
        state after an additional call to move_it_in_display_line_to, keep
        the values of it->max_ascent and it->max_descent found for the
        entire line.
        (pos_visible_p): Revert the comparison against bottom_y to what it
        was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
        (Bug#11464)

2012-05-26  Paul Eggert  <eggert@cs.ucla.edu>

        Fix coding-related core dumps with gcc -ftrapv.
        The code was computing A - B, where A and B are pointers, and B is
        random garbage.  This can lead to core dumps on platforms that
        have special pointer registers, and it also leads to core dumps on
        x86-64 when compiled with gcc -ftrapv.  The fix is to compute
        A - B only when B is initialized properly.
        * coding.c (coding_set_source, coding_set_destination): Return void.
        (coding_change_source, coding_change_destinations): New functions,
        with the old behaviors of coding_set_source and coding_set_destination.
        All callers that need an offset changed to use these new functions.

2012-05-26  Glenn Morris  <rgm@gnu.org>

        * nsterm.m (ns_init_paths): Don't mess with INFOPATH.  (Bug#2791)

2012-05-26  Eli Zaretskii  <eliz@gnu.org>

        Extend mouse support on W32 text-mode console.
        * xdisp.c (draw_row_with_mouse_face):
        Call tty_draw_row_with_mouse_face for WINDOWSNT as well.

        * w32console.c: Include window.h.
        (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
        New functions.
        (initialize_w32_display): Initialize mouse-highlight data.

        * w32inevt.c: Include termchar.h and window.h.
        (do_mouse_event): Support mouse-autoselect-window.  When the mouse
        moves, call note_mouse_highlight.  If help_echo changed, call
        gen_help_event to produce help-echo message in the echo area.
        Call clear_mouse_face if mouse_face_hidden is set in the mouse
        highlight info.

2012-05-26  Paul Eggert  <eggert@cs.ucla.edu>

        * lread.c (read1): Simplify slightly to avoid an overflow warning
        with GCC 4.7.0 on x86-64.

2012-05-26  Eli Zaretskii  <eliz@gnu.org>

        * bidi.c (bidi_mirror_char): Revert last change: an int is
        definitely wide enough here.

2012-05-25  Paul Eggert  <eggert@cs.ucla.edu>

        Fix integer width and related bugs (Bug#9874).
        * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
        (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
        (string_bytes, check_sblock, allocate_string_data):

        (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
        (mark_vectorlike):
        Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
        (allocate_pseudovector):
        Use int, not EMACS_INT, where int is wide enough.
        (inhibit_garbage_collection, Fgarbage_collect):
        Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
        * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
        int might not be wide enough.
        (bidi_cache_search, bidi_cache_find, bidi_init_it)
        (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
        (bidi_at_paragraph_end, bidi_find_paragraph_start)
        (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
        (bidi_level_of_next_char, bidi_move_to_visually_next):
        Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
        * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
        (Fkill_buffer, Fset_buffer_major_mode)
        (advance_to_char_boundary, Fbuffer_swap_text)

        (Foverlay_recenter, last_overlay_modification_hooks_used)
        (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
        Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
        (validate_region): Omit unnecessary test for b <= e,
        since that's guaranteed by the previous test.
        (adjust_overlays_for_delete): Avoid pos + length overflow.
        (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
        (report_overlay_modification):
        Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
        (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
        Omit pointer cast, which isn't needed anyway, and doesn't work
        after the EMACS_INT -> ptrdiff_t change.
        (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
        * buffer.h: Adjust decls to match defn changes elsewhere.
        (struct buffer_text, struct buffer):
        Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
        Use EMACS_INT, not int, where int might not be wide enough.
        * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
        not int, to avoid needless 32-bit limit on 64-bit hosts.
        (exec_byte_code): Use tighter memory-full test, one that checks
        for alloca overflow.  Don't compute the address of the object just
        before an array, as that's not portable.  Use EMACS_INT, not
        ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
        * callint.c (Fcall_interactively):
        Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
        * callproc.c (call_process_kill, Fcall_process):
        Don't assume pid_t fits into an Emacs fixnum.
        (call_process_cleanup, Fcall_process, child_setup):
        Don't assume pid_t fits into int.
        (call_process_cleanup, Fcall_process, delete_temp_file)
        (Fcall_process_region):
        Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
        (Fcall_process): Simplify handling of volatile integers.
        Use int, not EMACS_INT, where int will do.
        * casefiddle.c (casify_object, casify_region, operate_on_word)
        (Fupcase_word, Fdowncase_word, Fcapitalize_word):
        Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
        (casify_object): Avoid integer overflow when overallocating buffer.
        * casetab.c (set_identity, shuffle): Prefer int to unsigned when
        either works.  Use lint_assume to convince GCC 4.6.1 that it's OK.
        * category.c (Fchar_category_set): Don't assume fixnum fits in int.
        * category.h (CATEGORYP): Don't assume arg is nonnegative.
        * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
        integers are now checked earlier.  All uses replaced with XINT.
        (ccl_driver):
        Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
        For CCL_MapSingle, check that content and value are in int range.
        (ccl_driver, Fregister_code_conversion_map):
        Check that Vcode_version_map_vector is a vector.
        (resolve_symbol_ccl_program): Check that vector header is in range.
        Always copy the vector, so that we can check its contents reliably
        now rather than having to recheck each instruction as it's being
        executed.  Check that vector words fit in 'int'.
        (ccl_get_compiled_code, Fregister_ccl_program)
        (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
        program indexes, to avoid needless 32-bit limit on 64-bit hosts.
        (Fccl_execute, Fccl_execute_on_string): Check that initial reg
        contents are in range.
        (Fccl_execute_on_string): Check that status is in range.
        * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
        * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
        Accept and return EMACS_INT, not int, because callers can pass values
        out of 'int' range.
        (c_string_width, strwidth, lisp_string_width, chars_in_text)
        (multibyte_chars_in_text, parse_str_as_multibyte)

        (str_as_unibyte, str_to_unibyte, string_count_byte8)
        (string_escape_byte8, Fget_byte):
        Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
        (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
        avoid mishandling large integers.
        * character.h: Adjust decls to match defn changes elsewhere.
        * charset.c (load_charset_map_from_file, find_charsets_in_text)
        (Ffind_charset_region):
        Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
        (load_charset_map_from_file): Redo idx calculation to avoid overflow.
        (load_charset_map_from_vector, Fdefine_charset_internal):
        Don't assume fixnum fits in int.
        (load_charset_map_from_vector, Fmap_charset_chars):
        Remove now-unnecessary CHECK_NATNUMs.
        (Fdefine_charset_internal): Check ranges here, more carefully.
        Don't rely on undefined behavior with signed left shift overflow.
        Don't assume unsigned int fits into fixnum, or that fixnum fits
        into unsigned int.  Don't require max_code to be a valid fixnum;
        that's not true for gb10830 4-byte on a 32-bit host.  Allow
        invalid_code to be a cons, for the same reason.  Require code_offset
        to be a character.  Avoid int overflow if max_char is close
        to INT_MAX.
        (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
        this is intended anyway and avoids some undefined behavior.
        (load_charset_map): Pass unsigned, not int, as 2nd arg of
        INDEX_TO_CODE_POINT, as that's what it expects.
        (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
        * charset.h (DECODE_CHAR): Return int, not unsigned;
        this is what was intended anyway, and it avoids undefined behavior.
        (CHARSET_OFFSET): Remove unused macro, instead of fixing its
        integer-overflow issues.
        (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
        Formerly, it returned EMACS_INT on 64-bit hosts in the common case
        where the argument is EMACS_INT, and this behavior is not intended.
        * chartab.c (Fmake_char_table, Fset_char_table_range)
        (uniprop_get_decoder, uniprop_get_encoder):
        Don't assume fixnum fits in int.
        * cmds.c (move_point): New function, that does the gist of
        Fforward_char and Fbackward_char, but does so while checking
        for integer overflow more accurately.
        (Fforward_char, Fbackward_char): Use it.
        (Fforward_line, Fend_of_line, internal_self_insert)
        (internal_self_insert):
        Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
        Fix a FIXME, by checking for integer overflow when calculating
        target_clm and actual_clm.
        * coding.c (detect_coding_XXX, encode_coding_XXX, CODING_DECODE_CHAR)

        (x_get_local_selection, x_reply_selection_request)
        (x_handle_selection_request, wait_for_property_change):
        Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
        (selection_data_to_lisp_data): Use short, not EMACS_INT, where
        short is wide enough.
        (x_send_client_event): Don't assume fixnum fits in int.
        * xterm.c (x_x_to_emacs_modifiers):
        Don't assume EMACS_INT overflows nicely into int.
        (x_emacs_to_x_modifiers): Use EMACS_INT, not int, because values
        may come from Lisp.
        (handle_one_xevent): NATNUMP can eval its arg twice.
        (x_connection_closed):
        Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
        * xterm.h: Adjust decls to match defn changes elsewhere.
        (struct scroll_bar): Use struct vectorlike_header
        rather than rolling our own approximation.
        (SCROLL_BAR_VEC_SIZE): Remove; not used.

2012-05-25  Glenn Morris  <rgm@gnu.org>

        * lisp.mk (lisp): Update for more files being compiled now.

2012-05-25  Stefan Monnier  <monnier@iro.umontreal.ca>

        (read_pure): Remove var.
        (unreadpure): Remove function.
        (readevalloop): Don't call read_list with -1 flag.
        (read1, read_vector): Don't test read_pure any more.
        (read_list): Simplify.

        * fileio.c, character.h: Minor style tweaks.

2012-05-24  Dmitry Antipov  <dmantipov@yandex.ru>

        * window.h (clip_changed): Remove useless declaration.

2012-05-22  Juanma Barranquero  <lekktu@gmail.com>

        * makefile.w32-in: Follow-up to 2012-05-22T16:20:27Z!eggert@cs.ucla.edu.
        (TAGS, TAGS-gmake, CONFIG_H): Remove further references to m/intel386.h.

2012-05-22  Paul Eggert  <eggert@cs.ucla.edu>

        Remove src/m/*.
        This directory predates autoconf and is no longer needed nowadays.
        Move its few remaining bits of functionality to where they're needed.
        * m/README, m/alpha.h, m/amdx86-64.h, m/ia64.h, m/ibmrs6000.h:
        * m/ibms390x.h, m/intel386.h, m/m68k.h, m/macppc.h, m/sparc.h:
        * m/template.h: Remove.
        * Makefile.in (M_FILE): Remove.  All uses removed.
        * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS):
        * lisp.h (USE_LSB_TAG):
        * mem-limits.h (EXCEEDS_LISP_PTR):
        Use VAL_MAX, not VALBITS, in #if.
        * lisp.h (EMACS_INT_MAX): New macro, useful in #if.
        (EMACS_UINT): Define unconditionally now.
        (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
        (BITS_PER_EMACS_INT): New constants, replacing
        what used to be in config.h, but not useful in #if.
        (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
        define them any more.
        (VAL_MAX): New macro.
        (VALMASK): Use it.
        * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
        BITS_PER_EMACS_INT, in #if.
        * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
        (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
        * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
        * s/ms-w32.h (DATA_START):
        Move here from removed file m/intel386.h.
        * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
        * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.

2012-05-21  Paul Eggert  <eggert@cs.ucla.edu>

        Assume C89 or later.
        * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.
        * alloc.c (overrun_check_malloc, overrun_check_realloc, xmalloc)
        (xrealloc):
        * buffer.c (mmap_free_1, mmap_enlarge): Omit needless casts.
        * editfns.c, fns.c, gmalloc.c, insdel.c, sysdep.c, termcap.c (NULL):
        * textprop.c, tparam.c (NULL): Remove.
        * ralloc.c, vm-limit.c (POINTER): Assume void * works.
        * regex.c (SIGN_EXTEND_CHAR): Assume signed char works.
        * regex.h (_RE_ARGS): Remove.  All uses rewritten to use prototypes.
        * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
        * xterm.c (input_signal_count): Assume volatile works.

2012-05-21  Ken Brown  <kbrown@cornell.edu>

        * xgselect.c (xg_select): Fix first argument in call to 'select'
        (bug#11508).

2012-05-20  Ken Brown  <kbrown@cornell.edu>

        * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
        [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.

2012-05-19  Ken Brown  <kbrown@cornell.edu>

        * xfns.c (x_in_use): Remove `static' qualifier.
        * xterm.h (x_in_use): Declare.
        * xgselect.c: Include xterm.h.
        (xg_select): Test `x_in_use' instead of `inhibit_window_system'
        and `display_arg' (bug#9754).

2012-05-19  Paul Eggert  <eggert@cs.ucla.edu>

        * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.

        * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
        * s/ms-w32.h (HAVE_FTIME): Remove; not needed.

2012-05-18  Eli Zaretskii  <eliz@gnu.org>

        Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.

        * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
        (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.

        * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
        reference to image_cache->refcount.
        (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.

2012-05-17  Juri Linkov  <juri@jurta.org>

        * search.c (Fword_search_regexp, Fword_search_backward)
        (Fword_search_forward, Fword_search_backward_lax)
        (Fword_search_forward_lax): Move functions to isearch.el
        (bug#10145, bug#11381).

2012-05-16  Paul Eggert  <eggert@cs.ucla.edu>

        * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).

2012-05-15  Stefan Monnier  <monnier@iro.umontreal.ca>

        * lread.c (init_obarray): Declare Qt and Qnil as special.

2012-05-14  Glenn Morris  <rgm@gnu.org>

        * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
        Put "libexec" before "bin", for the sake of init_callproc_1.

2012-05-14  Paul Eggert  <eggert@cs.ucla.edu>

        * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.

        * unexaix.c: Port to more-recent AIX compilers.
        (report_error, report_error_1, make_hdr, copy_sym)
        (mark_x, adjust_lnnoptrs, unrelocate_symbols):
        Make arguments const char *, not char *, to avoid violations of C
        standard and to fix some AIX warnings reported by Gilles Pion.

2012-05-14  Eli Zaretskii  <eliz@gnu.org>

        * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
        already have overlays loaded.
        (handle_single_display_spec): Before returning without displaying
        fringe bitmap, synchronize the bidi iterator with the main display
        iterator, by calling iterate_out_of_display_property.
        (iterate_out_of_display_property): Detect buffer iteration by
        testing that it->string is a Lisp string.
        (get_next_display_element): When the current object is exhausted,
        and there's something on it->stack, call set_iterator_to_next to
        proceed with what's on the stack, instead of returning zero.
        (set_iterator_to_next): If called at the end of a Lisp string,
        proceed to consider_string_end without incrementing string
        position.  Don't increment display vector index past the end of
        the display vector.  (Bug#11417)
        (pos_visible_p): Don't report a position visible when move_it_to
        stopped at the last line of window, which happens to be scanned
        backwards by the bidi iteration.  (Bug#11464)

2012-05-14  Eli Zaretskii  <eliz@gnu.org>

        * xdisp.c (handle_single_display_spec): Return 1 for left-margin
        and right-margin display specs even if the spec is invalid or we
        are on a TTY, and thus unable to display on the fringes.
        That's because the text with the property will not be displayed anyway,
        so we need to signal to the caller that this is a "replacing"
        display spec.  This fixes display when the spec is invalid or we
        are on a TTY.

2012-05-14  Paul Eggert  <eggert@cs.ucla.edu>

        * unexaix.c (make_hdr): Fix typo in prototype.
        This bug broke the build on AIX.  Problem reported by Gilles Pion.

2012-05-14  Michael Albinus  <michael.albinus@gmx.de>

        * keyboard.c (kbd_buffer_get_event): Read special events also in
        batch mode.  (Bug#11415)

2012-05-12  Glenn Morris  <rgm@gnu.org>

        * ns.mk: Update for ns_appbindir no longer having trailing "/".

2012-05-12  Eli Zaretskii  <eliz@gnu.org>

        * lisp.mk (lisp): Add newcomment.elc.

2012-05-12  Glenn Morris  <rgm@gnu.org>

        * Makefile.in (MKDIR_P): New, set by configure.
        * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.

2012-05-11  Paul Eggert  <eggert@cs.ucla.edu>

        Remove unused function hourglass_started.
        * dispextern.h (hourglass_started):
        * w32fns.c (hourglass_started):
        * xdisp.c (hourglass_started): Remove.

2012-05-10  Juanma Barranquero  <lekktu@gmail.com>

        * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
        Update dependencies.

2012-05-10  Paul Eggert  <eggert@cs.ucla.edu>

        * xgselect.c (xg_select): Put maxfds+1 into a var.
        This is slightly clearer, and pacifies Ubuntu 12.04 gcc.

        * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.

2012-05-10  Dave Abrahams  <dave@boostpro.com>

        * filelock.c (syms_of_filelock): New boolean create-lockfiles.
        (lock_file): If create_lockfiles is 0, do nothing.  (Bug#11227)

2012-05-09  Michael Albinus  <michael.albinus@gmx.de>

        * dbusbind.c (xd_registered_buses): New internal Lisp object.
        Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
        (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
        Initialize xd_registered_buses.

2012-05-09  Paul Eggert  <eggert@cs.ucla.edu>

        Untag more efficiently if USE_LSB_TAG.
        This is based on a proposal by YAMAMOTO Mitsuharu in
        <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
        For an admittedly artificial (nth 8000 longlist) benchmark on
        Fedora 15 x86-64, this yields a 25% CPU speedup.  Also, it shrinks
        Emacs's overall text size by 1%.
        * lisp.h (XUNTAG): New macro.
        (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
        (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
        (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
        * eval.c (Fautoload):
        * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
        * frame.h (XFRAME): Use XUNTAG.

        Port recent dbusbind.c changes to 32-bit --with-wide-int.
        * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
        Remove unportable assumptions about print widths of types like
        dbus_uint32_t.
        (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
        intptr_t when converting between pointer and integer, to avoid GCC
        warnings about wrong width.

2012-05-09  Eli Zaretskii  <eliz@gnu.org>

        * w32proc.c (new_child): Force Windows to reserve only 64KB of
        stack for each reader_thread, instead of defaulting to 8MB
        determined by the linker.  This avoids failures in creating
        subprocesses on Windows 7, see the discussion in this thread:
        http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.

2012-05-07  Jérémy Compostella  <jeremy.compostella@gmail.com>

        Fix up display of the *Minibuf-0* buffer in the mini window.
        * keyboard.c (read_char): Don't clear the echo area if there's no
        message to clear.
        * xdisp.c (redisplay_internal): Redisplay the mini window (with the
        contents of *Minibuf-0*) if there's no message displayed in its stead.

2012-05-07  Michael Albinus  <michael.albinus@gmx.de>

        * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
        batch mode.

2012-05-06  Chong Yidong  <cyd@gnu.org>

        * lisp.mk (lisp): Update.

2012-05-05  Jim Meyering  <meyering@redhat.com>

        * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).

2012-05-04  Stefan Monnier  <monnier@iro.umontreal.ca>

        * data.c (PUT_ERROR): New macro.
        (syms_of_data): Use it.  Add new error type `user-error'.
        * undo.c (user_error): New function.
        (Fprimitive_undo): Use it.
        * print.c (print_error_message): Adjust print style for `user-error'.
        * keyboard.c (user_error): New function.
        (Fexit_recursive_edit, Fabort_recursive_edit): Use it.

2012-05-03  Paul Eggert  <eggert@cs.ucla.edu>

        Do not limit current-time-string to years 1000..9999.
        * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
        (Fcurrent_time_string): Support any year that is supported by the
        underlying localtime representation.  Don't use asctime, as it
        has undefined behavior for years outside the range -999..9999.

2012-05-02  Paul Eggert  <eggert@cs.ucla.edu>

        Fix race conditions involving setenv, gmtime, localtime, asctime.
        Without this fix, interrupts could mess up code that uses these
        nonreentrant functions, since setting TZ invalidates existing
        tm_zone or tzname values, and since most of these functions return
        pointers to static storage.
        * editfns.c (format_time_string, Fdecode_time, Fencode_time)
        (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
        Grow the critical sections to include not just invoking
        localtime/gmtime, but also accessing these functions' results
        including their tm_zone values if any, and any related TZ setting.
        (format_time_string): Last arg is now struct tm *, not struct tm **,
        so that the struct tm is saved in the critical section.
        All callers changed.  Simplify allocation of initial buffer, partly
        motivated by the fact that memory allocation needs to be outside
        the critical section.

2012-05-02  Dmitry Antipov  <dmantipov@yandex.ru>

        * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
        with RESET_INTERVAL.

        * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
        Remove duplicated buffer name initialization.

2012-05-02  Jim Meyering  <jim@meyering.net>

        * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).

        * xfns.c (x_window): Use xstrdup (Bug#11375).

2012-05-02  Eli Zaretskii  <eliz@gnu.org>

        * xdisp.c (pos_visible_p): If already at a newline from the
        display string before the 'while' loop, don't walk back the glyphs
        from it3.glyph_row.  Solves assertion violation when the display
        string begins with a newline (egg.el).  (Bug#11367)

2012-05-01  Stefan Monnier  <monnier@iro.umontreal.ca>

        * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
        Move to simple.el.

2012-05-01  Glenn Morris  <rgm@gnu.org>

        * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
        s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
        and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
        All were removed before 23.1.

        * dispnew.c: Remove HAVE_LIBNCURSES test;
        it is always true on relevant platforms.

        * Makefile.in (LD_SWITCH_X_SITE_RPATH):
        Rename from LD_SWITCH_X_SITE_AUX_RPATH.

        * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.

2012-04-30  Andreas Schwab  <schwab@linux-m68k.org>

        * .gdbinit (xpr): Remove checks for no longer existing misc types.
        (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
        Remove.

2012-04-28  Paul Eggert  <eggert@cs.ucla.edu>

        Do not avoid creating empty evaporating overlays (Bug#9642).
        * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
        That is, do not delete an evaporating overlay if it becomes
        empty after its bounds are adjusted to fit within its buffer.
        This fix caused other problems, and I'm reverting it until we get
        to the bottom of them.

2012-04-27  Chong Yidong  <cyd@gnu.org>

        * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).

2012-04-27  Eli Zaretskii  <eliz@gnu.org>

        * xdisp.c (pos_visible_p): If the window start position is beyond
        ZV, start the display from buffer beginning.  Prevents assertion
        violation in init_iterator when the minibuffer window is scrolled
        via the scroll bar.

        * window.c (window_scroll_pixel_based): Likewise.

2012-04-27  Chong Yidong  <cyd@gnu.org>

        * keymap.c (where_is_internal): Doc fix (Bug#10872).

2012-04-27  Glenn Morris  <rgm@gnu.org>

        * fileio.c (Fcopy_file, Fset_file_selinux_context):
        Ignore ENOTSUP failures from setfilecon functions.  (Bug#11245)

2012-04-27  Eli Zaretskii  <eliz@gnu.org>

        * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
        Don't overrun array limits of glyph row's used[] array.  (Bug#11288)

2012-04-26  Eli Zaretskii  <eliz@gnu.org>

        * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
        display element, check also the underlying string or buffer
        character.  (Bug#11341)

        * w32menu.c: Include w32heap.h.
        (add_menu_item): If the call to AppendMenuW (via
        unicode_append_menu) fails, disable Unicode menus only if we are
        running on Windows 9X/Me.

2012-04-24  Andreas Schwab  <schwab@linux-m68k.org>

        * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.

        Do not create empty overlays with the evaporate property (Bug#9642).
        * buffer.c (Fmove_overlay): Delete an evaporating overlay
        if it becomes empty after its bounds are adjusted to fit within
        its buffer.  Without this fix, in a nonempty buffer (let ((o
        (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
        yields an empty overlay that has the evaporate property, which is
        not supposed to happen.

2012-04-09  Eli Zaretskii  <eliz@gnu.org>

        * xdisp.c (set_cursor_from_row): If the display string appears in
        the buffer at position that is closer to point than the position
        after the display string, display the cursor on the first glyph of
        the display string.  Fixes cursor display when a 'display' text
        property immediately follows invisible text.  (Bug#11094)

        composite.c: use 'double' consistently
        * composite.c (get_composition_id): Use 'double' consistently

        (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
        (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
        [!WINDOWSNT]: New macros.
        (init_libxml2_functions, libxml2_loaded_p): New functions.
        (parse_region): Call fn_xmlCheckVersion instead of using the macro
        LIBXML_TEST_VERSION.  Call libxml2 functions via the fn_* macros.
        (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
        Calls xmlCleanupParser only if libxml2 was loaded (or statically
        linked in).
        (Flibxml_parse_html_region, Flibxml_parse_xml_region):
        Call init_libxml2_functions before calling libxml2 functions.
        (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.

        * emacs.c: Don't include libxml/parser.h.
        (shut_down_emacs): Call xml_cleanup_parser, instead of calling
        xmlCleanupParser directly.

        * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.

2012-04-07  Eli Zaretskii  <eliz@gnu.org>

        * indent.c (Fvertical_motion): If there is a display string at
        point, use it.vpos to compute how many lines to backtrack after
        move_it_to point.  (Bug#11133)

2012-04-06  Eli Zaretskii  <eliz@gnu.org>

        * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
        * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
        about subtle differences between FETCH_CHAR* and STRING_CHAR*
        macros related to unification of CJK characters.  For the details,
        see the discussion following the message here:
        http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.

2012-04-04  Chong Yidong  <cyd@gnu.org>

        instead of alloca.  (Bug#11138)

2012-04-01  Andreas Schwab  <schwab@linux-m68k.org>

        * w32menu.c (is_simple_dialog): Properly check lisp types.
        (Bug#11141)

2012-03-31  Eli Zaretskii  <eliz@gnu.org>

        * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
        position we get to after a call to move_it_to fails the
        IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
        only if we wind up in a string from display property.  (Bug#11063)

        * window.c (Fdelete_other_windows_internal): Invalidate the row
        and column information about mouse highlight, so that redisplay
        restores it after reallocating the glyph matrices.  (Bug#7464)

        * xdisp.c (set_cursor_from_row): If `cursor' property on a display
        string comes from a `display' text property, use the buffer
        position of that property as if we actually saw that position in
        the row's glyphs.
        (move_it_by_lines): Remove the assertion that
        "it->current_x == 0 && it->hpos == 0" which can be legitimately
        violated when there's a before-string at the beginning of a line.
        (Bug#11063)

2012-03-30  Eli Zaretskii  <eliz@gnu.org>

        * xdisp.c (append_space_for_newline): If the default face was
        remapped, use the remapped face for the appended newline.
        (extend_face_to_end_of_line): Use the remapped default face for
        extending the face to the end of the line.
        (display_line): Call extend_face_to_end_of_line when the default
        face was remapped.  (Bug#11068)

2012-03-29  Eli Zaretskii  <eliz@gnu.org>

        * s/ms-w32.h: Discourage from defining HAVE_GETCWD.

2012-03-28  Stefan Monnier  <monnier@iro.umontreal.ca>

        * keyboard.c (safe_run_hooks_error): Don't unquote strings.

2012-03-27  Glenn Morris  <rgm@gnu.org>

        * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
        Doc fixes.

2012-03-26  Kenichi Handa  <handa@m17n.org>

        * dispextern.h (struct glyph): Fix previous change.  Change the
        bit length of glyphless.ch to 25 (Bug#11082).

2012-03-26  Chong Yidong  <cyd@gnu.org>

        * keyboard.c (Vselection_inhibit_update_commands): New variable.
        (command_loop_1): Use it; inhibit selection update for
        handle-select-window too (Bug#8996).

2012-03-25  Fabrice Popineau  <fabrice.popineau@supelec.fr>

        * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.

2012-03-25  Kenichi Handa  <handa@m17n.org>

        * dispextern.h (struct glyph): Change the bit length of
        glyphless.ch to 22 to make the member glyphless fit in 32 bits.

2012-03-24  Eli Zaretskii  <eliz@gnu.org>

        * s/ms-w32.h (tzname): Include time.h before redirecting to
        _tzname.  Fixes the MSVC build.  (Bug#9960)

2012-03-24  Andreas Schwab  <schwab@linux-m68k.org>

        * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
        characters.

        * xterm.c (XTread_socket): Only modify handling_signal if
        !SYNC_INPUT.  (Bug#11080)

2012-03-23  Eli Zaretskii  <eliz@gnu.org>

        * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
        FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES.  Prevents crashes
        when fetching a multibyte character consumes more bytes than
        CHAR_BYTES returns, due to unification of CJK characters in
        string_char.  (Bug#11073)

2012-03-23  Troels Nielsen  <bn.troels@gmail.com>  (tiny change)

        * process.c (wait_reading_process_output): Handle pty disconnect
        by refraining from sending oneself a SIGCHLD (bug#10933).

2012-03-22  Chong Yidong  <cyd@gnu.org>

        * dispextern.h (struct it): New member string_from_prefix_prop_p.

        Mark string as coming from a prefix property.
        (handle_face_prop): Use default face for prefix strings (Bug#4281).
        (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.

2012-03-20  Eli Zaretskii  <eliz@gnu.org>

        * w32proc.c (Fw32_set_console_codepage)
        (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
        Doc fixes.

2012-03-20  Chong Yidong  <cyd@gnu.org>

        * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
        to reflect default non-nil value of redisplay-dont-pause.

        * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
        it fit in a valid range (Bug#11003).

2012-03-18  Eli Zaretskii  <eliz@gnu.org>

        * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
        that is not from display property, accept the row as a "cursor
        row" if one of the string's character has a non-nil `cursor'
        property.  Fixes cursor positioning when there are newlines in
        overlay strings, e.g. in icomplete.el.  (Bug#11035)

2012-03-12  Paul Eggert  <eggert@cs.ucla.edu>

        * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).

2012-03-12  Chong Yidong  <cyd@gnu.org>

        * eval.c (inhibit_lisp_code): Rename from
        inhibit_window_configuration_change_hook; move from window.c.

        * xfns.c (unwind_create_frame_1, Fx_create_frame):
        * window.c (run_window_configuration_change_hook)
        (syms_of_window): Callers changed.

2012-03-08  Jan Djärv  <jan.h.d@swipnet.se>

        * gtkutil.c (x_wm_set_size_hint): Use one row in call to
        FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
        zero (Bug#10954).

2012-03-03  Glenn Morris  <rgm@gnu.org>

        * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.

2012-03-02  Eli Zaretskii  <eliz@gnu.org>

        * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
        position past the first glyph_row that ends at ZV.  (Bug#10902)
        (redisplay_window, next_element_from_string): Fix typos in
        comments.
        (redisplay_window): Pass to move_it_vertically the margin in
        pixels, not in screen lines.

2012-03-02  Glenn Morris  <rgm@gnu.org>

        * buffer.c (buffer-list-update-hook): Doc fix.

2012-02-29  Eli Zaretskii  <eliz@gnu.org>

        * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
        push_it before setting up the iterator for the first overlay
        string, even if we have an empty string loaded.
        (next_overlay_string): If there's an empty string on the iterator
        stack, pop the stack.  (Bug#10903)

2012-02-25  Paul Eggert  <eggert@cs.ucla.edu>

        Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
        Suggested by Stefan Monnier in
        <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
        * alloc.c (widen_to_Lisp_Object): New static function.
        (mark_memory): Also mark Lisp_Objects by fetching pointer words
        and widening them to Lisp_Objects.  This would work even if
        USE_LSB_TAG is defined and wide integers are used, which might
        happen in a future version of Emacs.

2012-02-25  Chong Yidong  <cyd@gnu.org>

        * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
        Doc fix.

        before saving to clipboard manager.

2012-02-24  Chong Yidong  <cyd@gnu.org>

        * keyboard.c (process_special_events): Handle all X selection
        requests in kbd_buffer, not just the next one (Bug#8869).

2012-02-23  Chong Yidong  <cyd@gnu.org>

        * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
        call when setting menu-bar-lines and tool-bar-lines parameters.
        (unwind_create_frame_1): New helper function.

        * window.c (inhibit_window_configuration_change_hook): New var.
        (run_window_configuration_change_hook): Obey it.
        (syms_of_window): Initialize it.

2012-02-22  Chong Yidong  <cyd@gnu.org>

        * fileio.c (Vfile_name_handler_alist): Doc fix.

        * buffer.c (Fget_file_buffer): Protect against invalid file
        handler return value.

2012-02-20  Paul Eggert  <eggert@cs.ucla.edu>

        * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
        when computing $valmask.

        Fix crash due to non-contiguous EMACS_INT (Bug#10780).
        * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
        (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
        It's useless in that case, and it can cause problems on hosts
        that allocate halves of EMACS_INT values separately.
        Reported by Dan Horák.  Diagnosed by Andreas Schwab in
        <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
        * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
        UINTPTR_MAX >> VALBITS == 0.  This is required by the above change;
        it avoids undefined behavior on hosts where shifting right by more
        than the word width has undefined behavior.

2012-02-19  Chong Yidong  <cyd@gnu.org>

        * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
        (Funhandled_file_name_directory, Ffile_name_as_directory)
        (Fdirectory_file_name, Fexpand_file_name)
        (Fsubstitute_in_file_name): Protect against invalid file handler
        return values (Bug#10845).

2012-02-18  Eli Zaretskii  <eliz@gnu.org>

        * .gdbinit (pitx): Fix incorrect references to fields of the

        <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.

2012-02-15  Chong Yidong  <cyd@gnu.org>

        * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
        marked as special.  Also, starting docstrings with * is obsolete.

        * gnutls.c (emacs_gnutls_write): Fix last change.

2012-02-13  Lars Ingebrigtsen  <larsi@gnus.org>

2012-02-12  Chong Yidong  <cyd@gnu.org>

        * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
        as that creates a dangerous corner case.

        * window.c (Fdelete_window_internal): Invalidate the mouse
        highlight (Bug#9904).

2012-02-12  Glenn Morris  <rgm@gnu.org>

        (Fx_disown_selection_internal, Fx_selection_exists_p)
        (Fx_selection_owner_p, Fx_get_selection_internal):
        Sync docs and argument specs with the xselect.c versions.

2012-02-11  Lars Ingebrigtsen  <larsi@gnus.org>

        * gnutls.c (emacs_gnutls_write): Don't infloop if sendto fails.

2012-02-07  Chong Yidong  <cyd@gnu.org>

        * buffer.c (Fbuffer_local_variables)
        (buffer_lisp_local_variables): Handle unbound vars correctly;
        don't let Qunbound leak into Lisp.

2012-02-07  Glenn Morris  <rgm@gnu.org>

        * image.c (Fimagemagick_types): Doc fix.

        * image.c (imagemagick-render-type): Change it from a lisp object
        to an integer.  Move the doc here from the lisp manual.
        Treat all values not equal to 0 the same.

2012-02-06  Chong Yidong  <cyd@gnu.org>

        * doc.c (store_function_docstring): Avoid applying docstring of
        alias to base function (Bug#2603).

2012-02-04  Eli Zaretskii  <eliz@gnu.org>

        * w32.c (get_emacs_configuration_options):
        Include --enable-checking, if specified, in the return value.

2012-02-04  Martin Rudalics  <rudalics@gmx.at>

        * dispnew.c (change_frame_size_1): Calculate new_frame_total_cols

        * keyboard.c (adjust_point_for_property): Don't position point
        before BEGV.  (Bug#10696)

2012-02-03  Paul Eggert  <eggert@cs.ucla.edu>

        Handle overflow when computing char display width (Bug#9496).
        * character.c (char_width): Return EMACS_INT, not int.
        (char_width, c_string_width): Check for overflow when
        computing the width; this is possible now that individual
        characters can have unbounded width.  Problem introduced
        by merge from Emacs 23 on 2012-01-19.

2012-02-02  Michael Albinus  <michael.albinus@gmx.de>

        * dbusbind.c (Fdbus_register_method): Mention the return value
        :ignore in the docstring.

2012-02-02  Kenichi Handa  <handa@m17n.org>

        (x_produce_glyphs): Cancel previous change.  If cmp->glyph_len is
        0, do not call append_composite_glyph.

2012-02-02  Kenichi Handa  <handa@m17n.org>

        * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to
        NULL (Bug#6988).
        (x_produce_glyphs): If the component of a composition is a null
        string, set it->pixel_width to 1 to avoid zero-width glyph.

2012-02-01  Eli Zaretskii  <eliz@gnu.org>

        * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
        first 2 arguments are identical.  This makes inserting large
        output from a subprocess an order of magnitude faster on
        MS-Windows, where all sbrk'ed memory is always contiguous.

2012-01-31  Glenn Morris  <rgm@gnu.org>

        (ALIGN_GCTYPEBITS) [_MSC_VER]: Define.
        (DECL_ALIGN) [_MSC_VER]: Use it, as MSVC doesn't like bit ops in
        this macro definition.

        * s/ms-w32.h (tzname): Redirect to _tzname for all values of
        _MSC_VER.

        * xdisp.c (redisplay_window): If cursor row is not fully visible
        after recentering, and scroll-conservatively is set to a large
        number, scroll window by a few more lines to make the cursor fully
        visible and out of scroll-margin.  (Bug#10105)
        (start_display): Don't move to the next line if the display should
        start at a newline that is part of a display vector or an overlay

2011-11-20  Paul Eggert  <eggert@cs.ucla.edu>

        Standardize on VIRT_ADDR_VARIES behavior (Bug#10042).
        Otherwise, valgrind does not work on some platforms.
        Problem reported by Andreas Schwab in
        <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
        * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
        is set, removing the need for VIRT_ADDRESS_VARIES.
        (PURE_P): Use a more-efficient implementation that needs just one
        comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
        number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
        to 4 (xorl, subq, cmpq, setbe).
        * alloc.c (pure): Always extern now, since that's the
        VIRT_ADDR_VARIES behavior.
        (PURE_POINTER_P): Use a single comparison, not two, for
        consistency with the new puresize.h.
        * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
        * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:

        * xdisp.c (x_write_glyphs, draw_phys_cursor_glyph)
        (erase_phys_cursor, update_window_cursor, show_mouse_face)
        (cursor_in_mouse_face_p): If the cursor position is out of bounds,
        behave as if the cursor position were at the window margin.

        * window.c (get_phys_cursor_glyph): If the window is hscrolled,
        and the cursor position is out of bounds, behave as if the cursor
        position were at the window margin.  (Bug#10075)

2011-11-18  Chong Yidong  <cyd@gnu.org>

        * window.c (Fwindow_combination_limit): Make first argument

        (add_row_entry): Add xassert to verify that ROW's hash code is valid.

        * xdisp.c (row_hash): New function, body extracted from
        compute_line_metrics.
        (compute_line_metrics): Call row_hash, instead of computing the
        hash code inline.

        * dispnew.c (verify_row_hash): Call row_hash for computing the
        hash code of a row, instead of duplicating code from xdisp.c.

2011-11-14  Eli Zaretskii  <eliz@gnu.org>

        * xdisp.c (display_line): Move the call to
        highlight_trailing_whitespace before the call to
        compute_line_metrics, since the latter needs to see the final
        faces of all the glyphs to compute ROW's hash value.
        Fixes assertion violations in row_equal_p.  (Bug#10035)

2011-11-14  Juanma Barranquero  <lekktu@gmail.com>

        * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,
        just return (bug#10044).

2011-11-12  Eli Zaretskii  <eliz@gnu.org>

        * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
        with user-defined heap size.  Bump the default size of the temacs
        heap to 27MB, to avoid memory warning when running temacs.
        ($(TEMACS)): Use HEAPSIZE instead of a hardcoded value.

        * dispnew.c (scrolling_window): Fix incorrect indices in accessing
        current_matrix and desired_matrix.  (Bug#9990)
        (verify_row_hash) [XASSERTS]: New function.
        (adjust_glyph_matrix, row_equal_p): Use it in xassert to verify
        that the hash value of glyph rows is correct.

        * xmenu.c (cleanup_widget_value_tree): New function.
        (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of

2011-11-06  Paul Eggert  <eggert@cs.ucla.edu>

        Fix some portability problems with 'inline'.

        (window_box_right, window_box_right_offset): Declare extern.
        Otherwise, these inline functions do not conform to C99 and
        are miscompiled by Microsoft compilers.  Reported by Eli Zaretskii in
        <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
        * intervals.c (adjust_intervals_for_insertion)

        extern inline functions 'offset_intervals' couldn't refer to it.
        (static_offset_intervals): Remove.
        (offset_intervals): Rewrite using the old contents of
        static_offset_intervals.  The old version didn't conform to C99

2011-10-28  Eli Zaretskii  <eliz@gnu.org>

        * xdisp.c (note_mouse_highlight): Initialize `part', to avoid a

        Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
        instead of calling the "wide" APIs directly.

        * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.

        * w32.h (syms_of_w32font): Add prototype.

2011-10-27  Chong Yidong  <cyd@gnu.org>

        * process.c (make_process): Set gnutls_state to NULL.

        * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
        non-NULL, regardless of GNUTLS_INITSTAGE.
        (Fgnutls_boot): Cleanups.  Call emacs_gnutls_deinit if we signal

2011-10-20  Eli Zaretskii  <eliz@gnu.org>

        * dispextern.h (struct bidi_it): New member next_en_type.

        * bidi.c (bidi_line_init): Initialize the next_en_type member.
        (bidi_resolve_explicit_1): When next_en_pos is valid for the
        current character, check also for next_en_type being WEAK_EN.
        (bidi_resolve_weak): Don't enter the expensive loop if the current
        position is before next_en_pos.  Record the bidi type of the first
        non-ET, non-BN character we find, in addition to its position.
        (bidi_level_of_next_char): Invalidate next_en_type when
        next_en_pos is over-stepped.

2011-10-20  Paul Eggert  <eggert@cs.ucla.edu>

        Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
        * editfns.c: Rewrite current-time-zone so that it invokes
        the equivalent of (format-time-string "%Z") to get the time zone name.
        This fixes a bug when the time zone name contains characters that
        need converting from the system time locale to Emacs internal format.
        This fixes a shortcoming that I introduced in my 1999-10-19 patch:
        that patch fixed format-time-string to do the conversion, but
        I forgot to fix current-time-zone.
        (format_time_string): New function, containing most of
        what Fformat_time_string used to contain.
        (Fformat_time_string): Rewrite in terms of format_time_string.
        This doesn't change this function's behavior.
        (current-time-zone): Rewrite to use format_time_string.
        This fixes the bug reported by Michael Schierl in
        <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
        Jason Rumney's 2007-06-07 change worked around this bug, but
        didn't fix it.
        * systime.h (tzname, timezone): Remove no-longer-used declarations.

2011-10-19  Eli Zaretskii  <eliz@gnu.org>

        * xdisp.c (start_display): If the character at POS is displayed
        via a display vector, reset IT->current.dpvec_index to zero.
        (try_window_reusing_current_matrix): If a line ends in a display
        vector or the next line starts in a display vector, continue
        redrawing the window even though the character position of
        start_row was reached.
        (Bug#9771, part 2)

2011-10-18  Chong Yidong  <cyd@gnu.org>

        * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
        with nobreak-char-display too.

2011-10-18  Eli Zaretskii  <eliz@gnu.org>

        Fix part 3 of bug#9771.
        * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
        (bidi_resolve_neutral): Don't enter the expensive loop looking for
        non-neutral characters if the current character is a paragraph
        separator (a.k.a. Newline).  This avoids running the same
        expensive loop twice, once when we consume the preceding newline
        and the other time when the line actually needs to be displayed.
        Avoid the loop when we see neutrals on the base embedding level
        following a character whose directionality is the same as the
        paragraph's.  This avoids running the expensive loop when a line
        ends in a long sequence of neutrals, like control characters.
        Add assertion against STRONG_AL type.  Slightly rearrange code
        that determines the type of a neutral given the first non-neutral
        that follows it.
        (bidi_level_of_next_char): Set next_en_pos to zero when
        invalidating its info.

2011-10-17  Eli Zaretskii  <eliz@gnu.org>

        * xdisp.c (push_display_prop): Determine whether to record string
        or buffer position by IT->string, not by IT->method.  Allow
        GET_FROM_DISPLAY_VECTOR as IT->method on entry.  (Bug#9771, part 4)
        (move_it_vertically_backward): Don't look for character position
        immediately after the newline when in a continuation line.
        (Bug#9771, part 1)

2011-10-15  Martin Rudalics  <rudalics@gmx.at>

        * window.c (coordinates_in_window): Rewrite and delabelize
        vertical border check.  (Bug#5357) (Bug#9618)

2011-10-14  Stefan Monnier  <monnier@iro.umontreal.ca>

        * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
        errors in XSetWindowBorder (bug#9310).

2011-10-13  Dmitry Antipov  <dmantipov@yandex.ru>

        * editfns.c (Fset_time_zone_rule): Replace free with xfree to
        avoid crash when xmalloc overrun checking is enabled.

2011-10-13  Eli Zaretskii  <eliz@gnu.org>

        * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
        itb.paragraph_dir to NEUTRAL_DIR.  Fixes an occasional incorrect
        cursor motion with <left> and <right> arrow keys.

        * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
        some callers set that themselves.

2011-10-12  Eli Zaretskii  <eliz@gnu.org>

        * xdisp.c (find_row_edges): Handle the case where ROW comes from a
        display string and the previous row comes from the same string and
        is empty.  (Bug#9739)  (Bug#9738)

2011-10-12  Stefan Monnier  <monnier@iro.umontreal.ca>

        * xdisp.c (get_visually_first_element): Remove old incorrect
        comments regarding the Unicode Line Separator character.

        * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.

2011-10-12  Dmitry Antipov  <dmantipov@yandex.ru>

        * alloc.c (Fgc_status): Do not access beyond zombies array
        boundary if nzombies > MAX_ZOMBIES.
        * alloc.c (dump_zombies): Add missing format specifier.

2011-10-12  Paul Eggert  <eggert@cs.ucla.edu>

        * xdisp.c (set_cursor_from_row): Simplify conditionals,
        to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.

        * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
        Some packages use them to denote characters with modifiers.

2011-10-11  Andreas Schwab  <schwab@linux-m68k.org>

        * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
        (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
        matching a pp-number.  Rename parameter var to var1.

2011-10-11  Stefan Monnier  <monnier@iro.umontreal.ca>

        * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).

2011-10-08  Glenn Morris  <rgm@gnu.org>

        * callint.c (Fcall_interactively): Give a more explicit error for the

        Don't advertise functionality which we discourage or doesn't work.

2011-10-07  Paul Eggert  <eggert@cs.ucla.edu>

        * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
        or sizeof.  __alignof__ gives the wrong answer on Fedora x86-64
        with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
        this makes Emacs dump core during garbage collection on rare
        occasions.  sizeof is obviously inferior to offsetof here, so
        stick with offsetof.
        (GC_POINTER_ALIGNMENT): New macro.
        (mark_memory): Omit 3rd (offset) arg; caller changed.
        Don't assume EMACS_INT alignment is the same as pointer alignment.

2011-10-03  Stefan Monnier  <monnier@iro.umontreal.ca>

        * keyboard.c (read_key_sequence_remapped): New var.
        (read_key_sequence): Compute remapping in the right buffer.
        (command_loop_1): Use read_key_sequence's remapping directly.

2011-10-02  Stefan Monnier  <monnier@iro.umontreal.ca>

        * dired.c (file_name_completion): Don't expand file name.
        (Ffile_name_completion, Ffile_name_all_completions): Expand file name
        before checking file name handler.

        * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
        they've been requested explicitly (bug#9591).

2011-10-01  Andreas Schwab  <schwab@linux-m68k.org>

        * keymap.c (Fsingle_key_description): Use make_specified_string
        instead of build_string to build string from push_key_description.
        (Bug#5193)

2011-09-30  Paul Eggert  <eggert@cs.ucla.edu>

        * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
        This fixes a Y2038 bug on 64-bit hosts.
        * buffer.c (reset_buffer):
        * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
        (Fclear_buffer_auto_save_failure):
        Use 0, not -1, to represent an unset failure time, since time_t
        might not be signed.

        Remove dependency on glibc malloc internals.
        * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
        Move back here from lisp.h, but with their new implementations.
        (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
        (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
        * charset.c (charset_table_init): New static var.
        (syms_of_charset): Use it instead of xmalloc.  This removes a
        dependency on glibc malloc internals.  See Eli Zaretskii's comment in
        <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
        * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
        Move back to alloc.c.
        (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
        (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.

2011-09-30  Jan Djärv  <jan.h.d@swipnet.se>

        * nsterm.m (windowDidResize): Call x_set_window_size only when
        ns_in_resize is true.  Otherwise set pixelwidth/height and
        call change_frame_size (Bug#9628).

2011-09-30  Paul Eggert  <eggert@cs.ucla.edu>

        Port --enable-checking=all to Fedora 14 x86-64.
        * charset.c (syms_of_charset): Also account for glibc malloc's
        internal overhead when calculating the initial malloc maximum.

        Port --enable-checking=all to Fedora 14 x86.
        * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
        Move to lisp.h.
        (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
        (overrun_check_realloc, overrun_check_free):
        Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
        That way, xmalloc returns a properly-aligned pointer even if
        XMALLOC_OVERRUN_CHECK is defined.  The old debugging code happened
        to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
        * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
        into account when calculating the initial malloc maximum.
        * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
        Move here from alloc.c, so that charset.c can use it too.
        Properly align; the old code wasn't right for common 32-bit hosts
        when configured with --enable-checking=all.
        (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
        (XMALLOC_OVERRUN_SIZE_SIZE): New macros.

2011-09-29  Eli Zaretskii  <eliz@gnu.org>

        * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
        use EDOM.

2011-09-28  Eli Zaretskii  <eliz@gnu.org>

        * xdisp.c (compute_display_string_end): If there's no display
        string at CHARPOS, return -1.

        * bidi.c (bidi_fetch_char): When compute_display_string_end
        returns a negative value, treat the character as a normal
        character not covered by a display string.  (Bug#9624)

2011-09-28  Juanma Barranquero  <lekktu@gmail.com>

        * lread.c (Fread_from_string): Fix typo in docstring.

2011-09-27  Eli Zaretskii  <eliz@gnu.org>

        * xdisp.c (handle_invisible_prop): If invisible text ends on a
        newline, reseat the iterator instead of bidi-iterating there one
        character at a time.  (Bug#9610)
        (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
        TO_CHARPOS if the bidi iterator is at base embedding level.

2011-09-27  Andreas Schwab  <schwab@linux-m68k.org>

        * lread.c (readevalloop): Use correct code for NBSP.

2011-09-24  Eli Zaretskii  <eliz@gnu.org>

        * dispnew.c (syms_of_display) <redisplay-dont-pause>:
        Default value is now t.  Doc fix.

        * indent.c (Fvertical_motion): Compute and apply the overshoot
        logic when moving up, not only when moving down.  Fix the
        confusing name and values of the it_overshoot_expected variable;
        logic changes accordingly.  (Bug#9254) (Bug#9549)

        * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
        CHARPOS is covered by a display string which includes newlines.
        (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
        is covered by a display string with embedded newlines.

2011-09-24  Michael Albinus  <michael.albinus@gmx.de>

        * dbusbind.c (Fdbus_register_signal): Add match rule to

        Fix docstring.

2011-09-24  Jim Meyering  <meyering@redhat.com>

        do not ignore write error for any output size
        The previous change was incomplete.
        While it makes emacs --batch detect the vast majority of stdout
        write failures, errors were still ignored whenever the output size is
        k * (BUFSIZ+1) - 4.  E.g., on a system with BUFSIZ of 4096,
          $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
              && echo FAIL: ignored write error
          FAIL: ignored write error
          $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
              && echo FAIL: ignored write error
          FAIL: ignored write error
        * emacs.c (Fkill_emacs): Also test ferror.  (Bug#9574)

2011-09-23  Andreas Schwab  <schwab@linux-m68k.org>

        * emacs.c (Fkill_emacs): In noninteractive mode exit
        non-successfully if a write error occurred on stdout.  (Bug#9574)

2011-09-21  Eli Zaretskii  <eliz@gnu.org>

        * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
        the xassert test.

        * dispextern.h (struct it): Update the comment documenting what
        can it->OBJECT be.

2011-09-20  Eli Zaretskii  <eliz@gnu.org>

        * xdisp.c (set_cursor_from_row): If the row ends in a newline from
        a display string, extend search for cursor position to end of row.
        (find_row_edges): If the row ends in a newline from a display
        string, increment its MATRIX_ROW_END_CHARPOS by one.  (Bug#9549)
        Handle the case of a display string with multiple newlines.
        (Fcurrent_bidi_paragraph_direction): Fix search for previous
        non-empty line.  Fixes confusing cursor motion with arrow keys at
        the beginning of a line that starts with whitespace.

2011-09-19  Lars Magne Ingebrigtsen  <larsi@gnus.org>

        * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is

        boolean (Bug#9154).

2011-09-18  Eli Zaretskii  <eliz@gnu.org>

        * xdisp.c (display_line): Record maximum and minimum buffer
        positions even if no glyphs were produced (e.g., by a zero-width
        stretch).  Fixes bug#9530 on a TTY.  Under word-wrap, don't record
        buffer positions that will be removed from the glyph row because
        they don't fit.
        (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
        column is beyond frame width: don't subtract 1 "pixel" when
        computing width of the stretch.
        (reseat_at_next_visible_line_start): Undo the change made on
        2011-09-17 that saved paragraph information and restored it after
        the call to `reseat'.  (Bug#9545)

2011-09-18  YAMAMOTO Mitsuharu  <mituharu@math.s.chiba-u.ac.jp>

        initialized, to pacify gcc -Wuninitialized.

        * fileio.c: Report proper errno when syscall falls.
        (Finsert_file_contents): Save and restore errno,
        so that report_file_error outputs the correct diagnostic.

2011-09-17  Eli Zaretskii  <eliz@gnu.org>

        * xdisp.c (reseat_at_next_visible_line_start): Keep information
        about the current paragraph and restore it after the call to reseat.

        * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
        (bidi_find_paragraph_start): Search back for paragraph beginning
        at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
        (bidi_move_to_visually_next): Only trigger paragraph-related
        computations when the last character is a newline or at EOB, not
        just any NEUTRAL_B.  (Bug#9470)

        * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
        truncated lines if point is covered by a display string.  (Bug#9524)

2011-09-16  Paul Eggert  <eggert@cs.ucla.edu>

        * xselect.c: Relax test for outgoing X longs (Bug#9498).
        (cons_to_x_long): New function.
        (lisp_data_to_selection_data): Use it.  Correct the test for
        short-versus-long data; it was negated.  Break out of vector
        loop, for efficiency, when a long datum is discovered.

2011-09-16  Stefan Monnier  <monnier@iro.umontreal.ca>

        (selection_data_to_lisp_data): Assume incoming selection data are
        signed integers, not unsigned.  This is to be consistent with
        outgoing selection data, which was modified to use signed integers
        in as part of the fix to Bug#9196 in response to Jan D.'s comment
        in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11

        value for non-existent files.

2011-09-11  Eli Zaretskii  <eliz@gnu.org>

        * fileio.c (Finsert_file_contents): If the file cannot be opened,
        set its "size" to -1.  This will set the modtime_size field of
        the corresponding buffer to -1, which is what
        verify-visited-file-modtime expects for files that do not exist.
        (Bug#9139)

2011-09-11  Paul Eggert  <eggert@cs.ucla.edu>

        * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
        here ...
        * lisp.h: ... from here.  push_key_description is no longer
        defined in keyboard.c, so its declaration should not be in
        lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
        logically belongs with push_key_description.

2011-09-10  Paul Eggert  <eggert@cs.ucla.edu>

        * buffer.h: Include <sys/types.h> instead of <time.h>.

        isnan: Fix porting problem to Solaris 10 with bundled gcc.
        Without this fix, the command to link temacs failed due to an
        undefined symbol __builtin_isnan.  This is because
        /usr/include/iso/math_c99.h #defines isnan(x) to
        __builtin_isnan(x), but the bundled gcc, which identifies itself
        as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
        a __builtin_isnan.
        * floatfns.c (isnan): #undef, and then #define to a clone of
        what's in data.c.
        (Fisnan): Always define, since it's always available now.
        (syms_of_floatfns): Always define isnan at the Lisp level.

2011-09-06  Paul Eggert  <eggert@cs.ucla.edu>

2011-09-06  Paul Eggert  <eggert@cs.ucla.edu>

        * fileio.c: Fix bugs with large file offsets (Bug#9428).
        The previous code assumed that file offsets (off_t values) fit in
        EMACS_INT variables, which is not true on typical 32-bit hosts.
        The code messed up by falsely reporting buffer overflow in cases
        such as (insert-file-contents "big" nil 1 2) into an empty buffer
        when "big" contains more than 2**29 bytes, even though this
        inserts just one byte and does not overflow the buffer.
        (Finsert_file_contents): Store file offsets as off_t
        values, not as EMACS_INT values.  Check for overflow when
        converting between EMACS_INT and off_t.  When checking for
        buffer overflow or for overlap, take the offsets into account.
        Don't use EMACS_INT for small values where int suffices.
        When checking for overlap, fix a typo: ZV was used where
        ZV_BYTE was intended.
        (Fwrite_region): Don't assume off_t fits into 'long'.
        * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.

        * dbusbind.c (xd_signature_cat): Rename from signature_cat.

2011-09-04  Paul Eggert  <eggert@cs.ucla.edu>

        sprintf-related integer and memory overflow issues (Bug#9412).

        * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
        (esprintf, exprintf, evxprintf): New functions.
        * keyboard.c (command_loop_level): Now EMACS_INT, not int.
        (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
        (modify_event_symbol): Do not assume that the length of
        name_alist_or_stem is safe to alloca and fits in int.
        (Fexecute_extended_command): Likewise for function name and binding.
        (Frecursion_depth): Wrap around reliably on integer overflow.
        * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
        since some callers pass EMACS_INT values.
        (Fsingle_key_description): Don't crash if symbol name contains more
        than MAX_ALLOCA bytes.
        * minibuf.c (minibuf_level): Now EMACS_INT, not int.
        (get_minibuffer): Arg is now EMACS_INT, not int.
        * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
        (esprintf, exprintf, evxprintf): New decls.
        * window.h (command_loop_level, minibuf_level): Reflect API changes.

        * dbusbind.c (signature_cat): New function.
        (xd_signature, Fdbus_register_signal):
        Do not overrun buffer; instead, report string overflow.

        * dispnew.c (add_window_display_history): Don't overrun buffer.
        Truncate instead; this is OK since it's just a log.

        * editfns.c (Fcurrent_time_zone): Don't overrun buffer
        even if the time zone offset is outlandishly large.
        Don't mishandle offset == INT_MIN.

        * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
        when creating daemon; the previous buffer-overflow check was incorrect.

        * eval.c (verror): Simplify by rewriting in terms of evxprintf,
        which has the guts of the old verror function.

        * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
        use SAFE_ALLOCA instead.  Use esprintf to avoid int-overflow issues.

        * font.c: Include <float.h>, for DBL_MAX_10_EXP.
        (font_unparse_xlfd): Don't blindly alloca long strings.
        Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
        fits in int, when using sprintf.  Use single snprintf to count
        length of string rather than counting it via multiple sprintfs;
        that's simpler and more reliable.
        (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
        (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
        sprintf, in case result does not fit in int.

        * fontset.c (num_auto_fontsets): Now printmax_t, not int.
        (fontset_from_font): Print it.

        * frame.c (tty_frame_count): Now printmax_t, not int.
        (make_terminal_frame, set_term_frame_name): Print it.
        (x_report_frame_params): In X, window IDs are unsigned long,
        not signed long, so print them as unsigned.
        (validate_x_resource_name): Check for implausibly long names,
        and don't assume name length fits in 'int'.
        (x_get_resource_string): Don't blindly alloca invocation name;
        use SAFE_ALLOCA.  Use esprintf, not sprintf, in case result does
        not fit in int.

        * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
        (xg_check_special_colors, xg_set_geometry):
        Make sprintf buffers a bit bigger, to avoid potential buffer overrun.

        * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
        Use esprintf, not sprintf, in case result does not fit in int.

        * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
        (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
        it as a large positive number.
        (Fexecute_kbd_macro): Don't assume repeat count fits in int.
        * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.

        * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
        in case result does not fit in int.

        * print.c (float_to_string): Detect width overflow more reliably.
        (print_object): Make sprintf buffer a bit bigger, to avoid potential
        buffer overrun.  Don't assume list length fits in 'int'.  Treat
        print length of 0 as 0, not as infinity; to be consistent with other
        uses of print length in this function.  Don't overflow print length
        index.  Don't assume hash table size fits in 'long', or that
        vectorlike size fits in 'unsigned long'.

        * process.c (make_process): Use printmax_t, not int, to format
        process-name gensyms.

        * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.

        * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
        to avoid potential buffer overrun.

        if X resource line is longer than 512 bytes.

        * xfns.c (x_window): Make sprintf buffer a bit bigger
        to avoid potential buffer overrun.

        * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.

        * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.

2011-09-04  Paul Eggert  <eggert@cs.ucla.edu>

        Integer overflow fixes for scrolling, etc.
        Without these, Emacs silently mishandles large integers sometimes.
        For example, "C-u 4294967297 M-x recenter" was treated as if
        it were "C-u 1 M-x recenter" on a typical 64-bit host.

        * xdisp.c (try_window_id): Check Emacs fixnum range before
        converting to 'int'.

        * window.c (window_scroll_line_based, Frecenter):
        Check that an Emacs fixnum is in range before assigning it to 'int'.
        (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
        values converted from Emacs fixnums.
        (Frecenter): Don't wrap around a line count if it is out of 'int'
        range; instead, treat it as an extreme value.
        (Fset_window_configuration, compare_window_configurations):
        Use ptrdiff_t, not int, for index that might exceed 2 GiB.

        * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
        that can exceed INT_MAX.  Check that EMACS_INT value is in range
        before assigning it to the (possibly-narrower) index.
        (match_limit): Don't assume that a fixnum can fit in 'int'.

        * print.c (print_object): Use ptrdiff_t, not int, for index that can
        exceed INT_MAX.

        * indent.c (position_indentation): Now takes ptrdiff_t, not int.
        (Fvertical_motion): Don't wrap around LINES values that don't fit
        in 'int'.  Instead, treat them as extreme values.  This is good
        enough for windows, which can't have more than INT_MAX lines anyway.

2011-09-03  Lars Magne Ingebrigtsen  <larsi@gnus.org>

        * Require libxml/parser.h to avoid compilation warning.

        * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.

        * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
        since this reportedly can destroy thread storage.

2011-08-30  Chong Yidong  <cyd@stupidchicken.com>

        * syntax.c (find_defun_start): Update all cache variables if
        exiting early (Bug#9401).

2011-08-30  Eli Zaretskii  <eliz@gnu.org>

        * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.

        * xdisp.c (produce_stretch_glyph): No longer static, compiled also
        when HAVE_WINDOW_SYSTEM is not defined.  Support both GUI and TTY
        frames.  Call tty_append_glyph in the TTY case.  (Bug#9402)

        * term.c (tty_append_glyph): New function.
        (produce_stretch_glyph): Static function and its prototype deleted.

        * dispextern.h (produce_stretch_glyph, tty_append_glyph):
        Add prototypes.

2011-08-29  Paul Eggert  <eggert@cs.ucla.edu>

        * image.c (parse_image_spec): Check for nonnegative, not for positive,
        when checking :margin (Bug#9390).
        (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
        Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
        so that the name doesn't mislead.  All uses changed.

2011-08-28  Johan Bockgård  <bojohan@gnu.org>

        * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
        set_tty_hooks.

2011-08-27  Eli Zaretskii  <eliz@gnu.org>

        * xdisp.c (move_it_to): Don't bail out early when reaching
        position beyond to_charpos, if we are scanning backwards.
        (move_it_vertically_backward): When DY == 0, make sure we get to
        the first character in the line after the newline.

2011-08-27  Paul Eggert  <eggert@cs.ucla.edu>

        * ccl.c: Improve and simplify overflow checking (Bug#9196).
        (ccl_driver): Do not generate an out-of-range pointer.
        (Fccl_execute_on_string): Remove unnecessary check for
        integer overflow, noted by Stefan Monnier in
        <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
        Remove a FIXME that didn't need fixing.
        Simplify the newly-introduced buffer reallocation code.

2011-08-27  Juanma Barranquero  <lekktu@gmail.com>

        * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.

2011-08-26  Paul Eggert  <eggert@cs.ucla.edu>

        Integer and memory overflow issues (Bug#9196).

        * doc.c (get_doc_string): Rework so that
        get_doc_string_buffer_size is the actual buffer size, rather than
        being 1 less than the actual buffer size; this makes xpalloc more
        convenient.

        * image.c (x_allocate_bitmap_record, cache_image):
        * xselect.c (Fx_register_dnd_atom):
        Simplify previous changes by using xpalloc.

        * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
        since either will do and ptrdiff_t is convenient with xpalloc.

        * charset.c (charset_table_size)
        (struct charset_sort_data.priority): Now ptrdiff_t.
        (charset_compare): Don't overflow if priorities differ greatly.
        (Fsort_charsets): Don't assume list length fits in int.
        Check for size-calculation overflow when allocating sort data.
        (syms_of_charset): Allocate an initial charset table that is
        just under 64 KiB, to avoid problems with glibc malloc and mmap.

        * cmds.c (internal_self_insert): Check for size-calculation overflow.

        * composite.h (struct composition.glyph_len): Now int, not unsigned.
        The actual value is always <= INT_MAX, and leaving it unsigned made
        overflow checking harder.

        * dispextern.h (struct glyph_matrix.rows_allocated)
        (struct face_cache.size): Now ptrdiff_t, for convenience in use
        with xpalloc.  The values are still always <= INT_MAX.

        * indent.c (compute_motion): Adjust to region_cache_forward sig change.

        * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
        (SAFE_NALLOCA): New macro.

        * region-cache.c (struct boundary.pos, find_cache_boundary)
        (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
        (set_cache_region, invalidate_region_cache)
        (revalidate_region_cache, know_region_cache, region_cache_forward)
        (region_cache_backward, pp_cache):
        Use ptrdiff_t, not EMACS_INT, since either will do.  This is needed
        so that ptrdiff_t * can be passed to xpalloc.
        (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
        beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
        (pp_cache): Don't assume cache_len fits in int.
        * region-cache.h: Adjust extern decls to match.

        * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
        EMACS_INT, since either will do, for xpalloc.

        * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
        (xnmalloc, xnrealloc, xpalloc): New functions.

        * bidi.c (bidi_shelve_header_size): New constant.
        (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
        (bidi_cache_ensure_space): Avoid integer overflow when allocating.

        * bidi.c (bidi_cache_shrink):
        * buffer.c (overlays_at, overlays_in, record_overlay_string)
        (overlay_strings):
        Don't update size of array until after memory allocation succeeds,
        because xmalloc/xrealloc may not return.
        (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
        now that we have proper integer overflow checking.
        (record_overlay_string, overlay_strings): Catch overflows when
        calculating size of overlay_str_buf.

        * callproc.c (Fcall_process): Check for size overflow when
        calculating size of args2.
        (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
        Normally we prefer signed values, but sticking with ptrdiff_t would
        require adding more-complicated checks.

        * ccl.c (Fccl_execute_on_string): Check for memory overflow.
        Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
        Redo buffer-overflow calculations to avoid integer overflow.
        Add a FIXME comment where memory seems to be over-allocated.

        * character.c (Fstring): Check for size-calculation overflow.

        * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
        unnecessary integer overflow.  Check for size overflow.
        (encode_coding_object): Don't update size until xmalloc succeeds.

        * composite.c (get_composition_id): Check for overflow in glyph
        length calculations.

        Integer and memory overflow fixes for display code.
        * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
        * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
        (scrolling_window): Check for overflow in size calculations.
        (line_draw_cost, realloc_glyph_pool, add_row_entry):

        (row_table_size): Now ptrdiff_t, not int.
        (scrolling_window): Avoid overflow in size calculations.
        Don't update size until allocation succeeds.
        * fns.c (concat): Check for overflow in size calculations.
        (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
        * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
        (NEXT_ALMOST_PRIME_LIMIT): New constant.

        * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
        (get_doc_string): Check for size calculation overflow.
        Don't update size until allocation succeeds.
        (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
        EMACS_INT, where ptrdiff_t will do.
        (Fsubstitute_command_keys): Check for string overflow.

        * editfns.c (set_time_zone_rule): Don't assume environment length
        fits in int.
        (message_length): Now ptrdiff_t, not int.
        (Fmessage_box): Don't update size until allocation succeeds.
        Don't assume message length fits in int.
        (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.

        * emacs.c (main): Do not reallocate argv, since there is a null at
        the end that can be overwritten, and this way there's no need to
        worry about size-calculation overflow.
        (sort_args): Check for size-calculation overflow.

        * eval.c (init_eval_once, grow_specpdl): Don't update size until
        alloc succeeds.
        (call_debugger, grow_specpdl): Redo calculations to avoid overflow.

        * frame.c (set_menu_bar_lines, x_set_frame_parameters)
        (x_set_scroll_bar_width, x_figure_window_size):
        Check for integer overflow.
        (x_set_alpha): Do not assume XINT fits in int.

        * frame.h (struct frame): Use int, not EMACS_INT, where int works.
        This is for the members text_lines, text_cols, total_lines, total_cols,
        where the system imposes an 'int' limit.

        * fringe.c (Fdefine_fringe_bitmap):
        Don't update size until alloc works.

        * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
        (ftfont_shape_by_flt): Check for integer overflow in size calculations.

        * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
        Check for size-calculation overflow.
        (get_utf8_string): Use ptrdiff_t, not size_t, where either will
        do, as we prefer signed integers.
        (id_to_widget.max_size, id_to_widget.used)
        (xg_store_widget_in_map, xg_remove_widget_from_map)
        (xg_get_widget_from_map, xg_get_scroll_id_for_window)
        (xg_remove_scroll_bar, xg_update_scrollbar_pos):
        Use and return ptrdiff_t, not int.
        (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
        * gtkutil.h: Change prototypes to match the above.

        * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
        are duplicate now that they've been promoted to lisp.h.
        (x_allocate_bitmap_record, x_alloc_image_color)
        (make_image_cache, cache_image, xpm_load):

        Check for size calculation overflow.
        (ct_colors_allocated_max): New constant.
        (x_to_xcolors, x_detect_edges): Reorder multiplicands to avoid
        overflow.

        * keyboard.c (read_char, menu_bar_items, tool_bar_items)
        (read_char_x_menu_prompt, read_char_minibuf_menu_width)
        (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
        Use ptrdiff_t, not int, to count maps.
        (read_char_minibuf_menu_prompt): Check for overflow in size
        calculations.  Don't update size until allocation succeeds.

        for command line length.  Do not attempt to address one before the
        beginning of an array, as that's not portable.

        * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of
        subtracting pointers.

        (Finternal_make_lisp_face, cache_face):
        Check for size calculation overflow.
        (cache_face): Treat size calculation overflows as if they were
        memory exhaustion (the usual treatment), rather than aborting.

        * xfns.c (x_encode_text, x_set_name_internal)
        (Fx_change_window_property): Use ptrdiff_t, not int, to count
        sizes, since they can exceed INT_MAX in size.  Check for size
        calculation overflow.

        * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
        (xg_select): Check for size calculation overflow.
        Don't update size until alloc done.

        * xrdb.c (get_environ_db): Don't assume path length fits in int,
        as sprintf is limited to int lengths.

        * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
        (X_LONG_MIN): New macros.
        Use them to make the following changes clearer.
        (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
        This change doesn't affect the value now, but it may help remind
        future maintainers not to raise the value too much later.
        (SELECTION_QUANTUM): Remove, replacing with ...
        (selection_quantum): ... new function, which avoids overflow.
        All uses changed.
        (struct selection_data.size): Now ptrdiff_t, not int, to avoid
        assumption that selection length fits in 'int'.

        (x_reply_selection_request, x_get_window_property)
        (receive_incremental_selection, x_property_data_to_lisp):
        Redo calculations to avoid overflow.
        (x_reply_selection_request): When sending hint, ceiling it at
        X_LONG_MAX rather than relying on wraparound overflow to send
        something.
        (x_get_window_property, receive_incremental_selection)
        (lisp_data_to_selection_data, x_property_data_to_lisp):

        (lisp_data_to_selection_data, Fx_register_dnd_atom):
        Don't store size until memory allocation succeeds.
        (x_get_window_property): Plug memory leak on memory exhaustion.
        Don't double-block input; malloc is safe here.  Don't assume 2**34
        - 4 fits in unsigned long.  Add an xassert to check
        XGetWindowProperty overflow.  Be more careful about overflow
        calculations, and distinguish size from memory overflow better.
        (receive_incremental_selection): When tracing, don't assume
        unsigned int is less than INT_MAX.
        (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
        harmful) conversions of unsigned short to int.
        (lisp_data_to_selection_data): Don't assume that integers
        in the range -65535 through -1 fit in an X unsigned short.
        Don't assume that ULONG_MAX == X_ULONG_MAX.  Don't store into
        result parameters unless successful.  Rely on cons_to_unsigned
        to report problems with elements; the old code wasn't right anyway.
        (x_check_property_data): Check for int overflow; we cannot use
        a wider type due to X limits.
        (x_handle_dnd_message): Use unsigned int, to avoid int overflow.

        * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.

        Don't assume alloca size is less than MAX_ALLOCA.
        (x_term_init): Don't assume length fits in int (sprintf is limited
        to int size).

        * lisp.h (hash_lookup, hash_put):
        * minibuf.c (Ftest_completion):
        Use ptrdiff_t for hash table indexes, not int (which is too
        narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
        32-bit --with-wide-int hosts).

        * charset.c (Fdefine_charset_internal): Check for integer overflow.
        Add a FIXME comment about memory leaks.
        (syms_of_charset): Don't assume xmalloc returns.

        * character.h (CHAR_WIDTH):
        * indent.c (MULTIBYTE_BYTES_WIDTH):
        Use sanitize_char_width to avoid undefined and/or bad behavior
        with outlandish widths.
        * character.h (sanitize_tab_width): Rename from sanitize_width,
        now that we have two such functions.  All uses changed.

        * xterm.c: Don't go over XClientMessageEvent limit.
        (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
        (x_send_scroll_bar_event): Likewise.  Check that the size does not
        exceed limits imposed by XClientMessageEvent, as well as the usual
        ptrdiff_t and size_t limits.

        * keyboard.c: Overflow, signedness and related fixes.
        (make_lispy_movement): Use same integer type in forward decl
        that is used in the definition.
        (read_key_sequence, keyremap_step):
        Change bufsize argument back to int, undoing my 2011-03-30 change.
        We prefer signed types, and int is wide enough here.
        (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
        than TYPE_MAXIMUM (EMACS_INT) / 2.  Don't let the label size grow
        larger than STRING_BYTES_BOUND.  Use ptrdiff_t for Emacs string
        length, not size_t.  Use ptrdiff_t for index, not int.
        (keyremap_step, read_key_sequence): Redo bufsize check to avoid
        possibility of integer overflow.

        (lookup_image): Remove unnecessary tests.
        (xbm_image_p): Locals are now of int, not EMACS_INT,
        since parse_image_check makes sure they fit into int.
        (png_load, gif_load, svg_load_image):
        Prefer int to unsigned where either will do.
        (tiff_handler): New function, combining the cores of the
        old tiff_error_handler and tiff_warning_handler.
        This function is rewritten to use vsnprintf and thereby avoid
        stack buffer overflows.  It uses only the features of vsnprintf
        that are common to both POSIX and native Microsoft.
        (tiff_error_handler, tiff_warning_handler): Use it.
        (tiff_load, gif_load, imagemagick_load_image):
        Don't assume :index value fits in 'int'.
        (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
        (imagemagick_load_image): Check that crop parameters fit into
        the integer types that MagickCropImage accepts.  Don't assume
        Vimagemagick_render_type has a nonnegative value.  Don't assume
        size_t fits in 'long'.
        (gs_load): Use printmax_t to print the widest integers possible.
        Check for integer overflow when computing image height and width.

        * xdisp.c (compute_display_string_pos): Return 2 in DISP_PROP when
        the display spec is of the form `(space ...)'.
        (handle_display_spec): Return the value returned by
        handle_single_display_spec, not just 1 or zero.
        (handle_single_display_spec): If the display spec is of the form
        `(space ...)', and specifies display in the text area, return 2
        rather than 1.
        (try_cursor_movement): Check for the need to scroll more
        accurately, and prefer exact match for point under bidi.
        Don't advance `row' beyond the last row of the window.

        * dispextern.h (struct bidi_it): Rename the disp_prop_p member
        into disp_prop; all users changed.

        * bidi.c (bidi_fetch_char): If compute_display_string_pos returns

        positioning on the newline at EOL of R2L text within L2R
        paragraph, and vice versa.
        (try_cursor_movement): Check continued rows, in addition to
        continuation rows.  Fixes unwarranted scroll when point enters a
        continued line of R2L text within an L2R paragraph, or vice versa.
        (cursor_row_p): Consider the case of point being equal to
        MATRIX_ROW_END_CHARPOS.  Prevents cursor being stuck when moving
        from the end of a short line to the beginning of a continued line
        of R2L text within L2R paragraph.
        (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
        composed characters.

        account for the height of the header line.  (Bug#8874)

        * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
        instead of CHAR_TO_BYTE.  Fixes a crash when a completion
        candidate is selected by the mouse, and that candidate has a
        composed character under the mouse.

        * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1.  Fixes pixel
        coordinates reported by pos-visible-in-window-p for a composed

        * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
        members before the level stack, so they would be saved and
        restored when copying iterator state.  Fixes incorrect reordering
        around TABs covered by display properties.

        the event loop.  Get status from as_status (Bug#7276).

        * nsterm.m (sendEvent): If event is NSApplicationDefined and
        data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
        the event loop (Bug#7276).

2011-08-14  Andreas Schwab  <schwab@linux-m68k.org>

        * gnutls.c (QCgnutls_bootprop_priority)
        (QCgnutls_bootprop_trustfiles, QCgnutls_bootprop_keylist)
        (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
        (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
        (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)
        (QCgnutls_bootprop_verify_hostname_error)
        (QCgnutls_bootprop_callbacks_verify): Rename from
        Qgnutls_bootprop_..., all uses changed.

        * xfaces.c (QCignore_defface): Rename from Qignore_defface, all
        uses changed.

2011-08-14  Paul Eggert  <eggert@cs.ucla.edu>

        * xfaces.c (Qframe_set_background_mode): Now static.
        * dispextern.h (Qframe_set_background_mode): Remove decl.

        * process.c (Fnetwork_interface_info): Declare local only if needed.

2011-08-13  Jan Djärv  <jan.h.d@swipnet.se>

        * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
        (Fnetwork_interface_list): Allocate in increments of bytes instead
        of sizeof (struct ifreq).  Iterate over ifconf.ifc_req by counting
        bytes (Bug#8477).  Count bytes correctly when ifr_addr is a struct
        sockaddr.
        (struct ifflag_def): notrailers is smart on OSX.
        (Fnetwork_interface_info): Handle case when ifr_flags is negative.
        Get hardware address with getifaddrs if available.

2011-08-12  Eli Zaretskii  <eliz@gnu.org>

        * xdisp.c (iterate_out_of_display_property): xassert that
        IT->position is set to within IT->object's boundaries.  Break from
        the loop as soon as EOB is reached; avoids infloops in redisplay
        when IT->position is set up wrongly due to some bug.
        Set IT->current to match the bidi iterator unconditionally.
        (push_display_prop): Allow GET_FROM_STRING as IT->method on
        entry.  Force push_it to save on the stack the current
        buffer/string position, to be restored by pop_it.  Fix flags in
        the iterator structure wrt the object coming from a display
        property, as `line-prefix' and `wrap-prefix' are not ``replacing''
        properties.  (Bug#9284)

2011-08-09  Andreas Schwab  <schwab@linux-m68k.org>

        * fontset.c (fontset_get_font_group): Add proper type checks.

2011-08-09  YAMAMOTO Mitsuharu  <mituharu@math.s.chiba-u.ac.jp>

        * unexmacosx.c (print_load_command_name): Add cases LC_FUNCTION_STARTS
        and LC_VERSION_MIN_MACOSX.
        (copy_linkedit_data) [LC_FUNCTION_STARTS]: New function.
        (dump_it) [LC_FUNCTION_STARTS]: Use it.

2011-08-08  Eli Zaretskii  <eliz@gnu.org>

        * xdisp.c (forward_to_next_line_start): Allow to use the
        no-display-properties-and-no-overlays under bidi display.
        Set disp_pos in the bidi iterator to avoid searches for display
        properties and overlays.

2011-08-08  Chong Yidong  <cyd@stupidchicken.com>

        * editfns.c (Fset_time_zone_rule): Document relationship with the
        setenv function.

        the font entity extracted from the cache (Bug#8109).

2011-08-07  Chong Yidong  <cyd@stupidchicken.com>

        * composite.c (autocmp_chars): Don't reset point.  That is done by
        restore_point_unwind (Bug#5984).

2011-08-07  Juri Linkov  <juri@jurta.org>

        * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
        to show the arg `TIME' instead of `TIMEVAL'.

2011-08-06  Eli Zaretskii  <eliz@gnu.org>

        * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
        display property strides EOL and includes a newline, as in
        longlines-mode.  (Bug#9254)
        (move_it_in_display_line_to): Fix vertical-motion in a buffer with
        word-wrap under bidirectional display.  (Bug#9224)

        * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
        is non-zero, even if the data buffer is NULL.  Fixes a crash in
        vertical-motion with longlines-mode.  (Bug#9254)

2011-08-05  Eli Zaretskii  <eliz@gnu.org>

        * bidi.c <bidi_cache_total_alloc>: Now static.
        (bidi_initialize): Initialize bidi_cache_total_alloc.

        * xdisp.c (display_line): Release buffer allocated for shelved bidi
        cache.  (Bug#9221)

        * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
        amount allocated this far in `bidi_cache_total_alloc'.
        (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
        non-zero, only free the data buffer without restoring the cache
        contents.  All callers changed.

        * dispextern.h (bidi_unshelve_cache): Update prototype.

        * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
        (move_it_in_display_line, move_it_to)
        (move_it_vertically_backward, move_it_by_lines): Replace the call
        to xfree to an equivalent call to bidi_unshelve_cache.
        (move_it_in_display_line_to): Fix logic of returning
        MOVE_POS_MATCH_OR_ZV in the bidi case.  (Bug#9224)

2011-08-05  Eli Zaretskii  <eliz@gnu.org>

        * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
        came from a string character with a `cursor' property.  (Bug#9229)

2011-08-04  Jan Djärv  <jan.h.d@swipnet.se>

        * Makefile.in (LIB_PTHREAD): New variable.
        (LIBES): Add LIB_PTHREAD (Bug#9216).

        * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
        Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).

2011-08-04  Andreas Schwab  <schwab@linux-m68k.org>

        * regex.c (re_iswctype): Remove some redundant boolean conversions.

2011-08-04  Jan Djärv  <jan.h.d@swipnet.se>

        * xterm.c (x_find_topmost_parent): New function.
        (x_set_frame_alpha): Find topmost parent window with
        x_find_topmost_parent and set the property there also (bug#9181).
        (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.

2011-08-04  Paul Eggert  <eggert@cs.ucla.edu>

        * callproc.c (Fcall_process): Avoid vfork clobbering
        the local vars buffer, coding_systems, current_dir.

2011-08-03  Stefan Monnier  <monnier@iro.umontreal.ca>

        * keymap.c (Fmake_composed_keymap): Move to subr.el.

2011-08-03  Paul Eggert  <eggert@cs.ucla.edu>

        * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
        so that it is not optimized away.

        * xdisp.c (compute_display_string_pos): Remove unused local.

2011-08-02  Eli Zaretskii  <eliz@gnu.org>

        Fix slow cursor motion and scrolling in large buffers with
        selective display, like Org Mode buffers.  (Bug#9218)

        * dispextern.h (struct bidi_it): New member disp_prop_p.

        * xdisp.c: Remove one-slot cache of display string positions.
        (compute_display_string_pos): Accept an additional argument
        DISP_PROP_P; callers changed.  Scan at most 5K characters forward
        for a display string or property.  If found, set DISP_PROP_P
        non-zero.

        * bidi.c (bidi_fetch_char): Accept an additional argument
        DISP_PROP_P, and pass it to compute_display_string_pos.
        Only handle text covered by a display string if DISP_PROP_P is returned
        non-zero.  All callers of bidi_fetch_char changed.

2011-08-02  Stefan Monnier  <monnier@iro.umontreal.ca>

        * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.

2010-12-03  Don March  <don@ohspite.net>

        * keymap.c (Fdefine_key): Fix non-prefix key error message when
        last character M-[char] is translated to ESC [char] (bug#7541).

2011-08-02  Kenichi Handa  <handa@m17n.org>

        * lisp.h (uniprop_table): Extern it.

        * chartab.c (uniprop_table): Make it non-static.

2011-08-01  Eli Zaretskii  <eliz@gnu.org>

        * xdisp.c (forward_to_next_line_start): Accept additional argument
        BIDI_IT_PREV, and store into it the state of the bidi iterator had
        on the newline.
        (reseat_at_next_visible_line_start): Use the bidi iterator state
        returned by forward_to_next_line_start to restore the state of
        it->bidi_it after backing up to previous newline.  (Bug#9212)

2011-07-30  Andreas Schwab  <schwab@linux-m68k.org>

        * regex.c (re_comp): Protoize.
        (re_exec): Fix return type.
        (regexec): Fix type of `ret'.  (Bug#9203)

2011-07-28  Paul Eggert  <eggert@cs.ucla.edu>

        * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
        This is needed if max-image-size is a floating-point number.

2011-07-28  Andreas Schwab  <schwab@linux-m68k.org>

        * print.c (print_object): Print empty symbol as ##.

        * lread.c (read1): Read ## as empty symbol.

2011-07-28  Alp Aker  <alp.tekin.aker@gmail.com>

        * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
        setting frame foreground color (Bug#9175).
        (x_set_background_color): Likewise.

        * nsmenu.m (-setText): Size tooltip dimensions precisely to
        contents (Bug#9176).
        (EmacsTooltip -init): Remove bezels and add shadows to
        tooltip windows.

        * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
        or scroll bar (Bug#8470).

        * nsfont.m (nsfont_open): Remove assignment to voffset and
        unnecessary vars hshink, expand, hd, full_height, min_height.
        (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).

        * nsterm.h (nsfont_info): Remove voffset field.

2011-07-28  Alp Aker  <alp.tekin.aker@gmail.com>

        Implement strike-through and overline on NextStep (Bug#8863).

        * nsfont.m (nsfont_open): Use underline position provided by font,
        instead of hard-coded value of 2.
        (nsfont_draw): Call ns_draw_text_decoration instead.

        * nsterm.h: Add declaration for ns_draw_text_decoration.

        * nsterm.m (ns_draw_text_decoration): New function for drawing
        underline, overline, and strike-through.
        (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
        ns_draw_text_decoration.  Change treatment of cursor drawing to
        accommodate underlining, etc.

2011-07-28  Eli Zaretskii  <eliz@gnu.org>

        * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
        default.

2011-07-28  Paul Eggert  <eggert@cs.ucla.edu>

        * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
        Without this fix, if a signal arrives just after memory fills up,
        'malloc' might be invoked reentrantly.

        * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
        In other words, assume that every image size is allowed, on non-X
        hosts.  This assumption is probably wrong, but it lets Emacs compile.

2011-07-28  Andreas Schwab  <schwab@linux-m68k.org>

        * regex.c (re_iswctype): Convert return values to boolean.

2011-07-28  Eli Zaretskii  <eliz@fencepost.gnu.org>

        * xdisp.c (compute_display_string_pos): Don't use cached display
        string position if the buffer had its restriction changed.
        (Bug#9184)

2011-07-28  Paul Eggert  <eggert@cs.ucla.edu>

        * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.

2011-07-28  Paul Eggert  <eggert@cs.ucla.edu>

        Integer signedness and overflow and related fixes.  (Bug#9079)

        * bidi.c: Integer size and overflow fixes.
        (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
        (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
        (bidi_cache_find_level_change, bidi_cache_ensure_space)
        (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
        (bidi_find_other_level_edge):
        Use ptrdiff_t instead of EMACS_INT where either will do.
        This works better on 32-bit hosts configured --with-wide-int.
        (bidi_cache_ensure_space): Check for size-calculation overflow.
        Use % rather than repeated addition, for better worst-case speed.
        Don't set bidi_cache_size until after xrealloc returns, because it
        might not return.
        (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
        (bidi_cache_ensure_space): Also check that the bidi cache size
        does not exceed that of the largest Lisp string or buffer.  See Eli
        Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.

        * alloc.c (__malloc_size_t): Remove.
        All uses replaced by size_t.  See Andreas Schwab's note
        <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.

        * image.c: Improve checking for integer overflow.
        (check_image_size): Assume that f is nonnull, since
        it is always nonnull in practice.  This is one less thing to
        worry about when checking for integer overflow later.
        (x_check_image_size): New function, which checks for integer
        overflow issues inside X.
        (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
        This removes the need for a memory_full check.
        (xbm_image_p): Rewrite to avoid integer multiplication overflow.
        (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
        (xbm_read_bitmap_data): Change locals back to 'int', since
        their values must fit in 'int'.
        (xpm_load_image, png_load, tiff_load):
        Invoke x_create_x_image_and_pixmap earlier,
        to avoid much needless work if the image is too large.
        (tiff_load): Treat overly large images as if
        x_create_x_image_and_pixmap failed, not as malloc failures.
        (gs_load): Use x_check_image_size.

        * gtkutil.c: Omit integer casts.
        (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
        (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.

        * image.c (png_load): Don't assume height * row_bytes fits in 'int'.

        * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
        Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
        would wrongly return t on a 64-bit host.

        * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
        The plain *_OVERFLOW macros run afoul of GCC bug 49705
        <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
        and therefore cause GCC to emit a bogus diagnostic in some cases.

        * image.c: Integer signedness and overflow and related fixes.
        This is not an exhaustive set of fixes, but it's time to
        record what I've got.
        (lookup_pixel_color, check_image_size): Remove redundant decls.
        (check_image_size): Don't assume that arbitrary EMACS_INT values
        fit in 'int', or that arbitrary 'double' values fit in 'int'.
        (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
        (tiff_load, imagemagick_load_image):
        Check for overflow in size calculations.
        (x_create_x_image_and_pixmap): Remove unnecessary test for
        xmalloc returning NULL; that can't happen.
        (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
        (xpm_color_bucket): Use better integer hashing function.
        (xpm_cache_color): Don't possibly over-allocate memory.
        (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
        (gif_memory_source):
        Use ptrdiff_t, not int or size_t, to record sizes.
        (png_load): Don't assume values greater than 2**31 fit in 'int'.
        (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
        either works, as we prefer signed integers.
        (tiff_read_from_memory, tiff_write_from_memory):
        Return tsize_t, not size_t, since that's what the TIFF API wants.
        (tiff_read_from_memory): Don't fail simply because the read would
        go past EOF; instead, return a short read.
        (tiff_load): Omit no-longer-needed casts.
        (Fimagemagick_types): Don't assume size fits into 'int'.

        Improve hashing quality when configured --with-wide-int.
        * fns.c (hash_string): New function, taken from sxhash_string.
        Do not discard information about ASCII character case; this
        discarding is no longer needed.
        (sxhash-string): Use it.  Change sig to match it.  Caller changed.
        * lisp.h: Declare it.
        * lread.c (hash_string): Remove, since we now use fns.c's version.
        The fns.c version returns a wider integer if --with-wide-int is
        specified, so this should help the quality of the hashing a bit.

        * emacs.c: Integer overflow minor fix.
        (heap_bss_diff): Now uprintmax_t, not unsigned long.  All used changed.
        Define only if GNU_LINUX.
        (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.

        * dispnew.c: Integer signedness and overflow fixes.
        Remove unnecessary forward decls, that were a maintenance hassle.
        (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
        All uses changed.
        (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
        (scrolling_window): Use ptrdiff_t, not int, for byte count.
        (prepare_desired_row, line_draw_cost):
        Use int, not unsigned, where either works.
        (save_current_matrix, restore_current_matrix):
        Use ptrdiff_t, not size_t, where either works.
        (init_display): Check for overflow more accurately, and without
        relying on undefined behavior.

        * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
        Remove, replacing with the new symbols in lisp.h.  All uses changed.
        * fileio.c (make_temp_name):
        * filelock.c (lock_file_1, lock_file):
        * xdisp.c (message_dolog):
        Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
        Use pMd etc. instead.
        * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
        replacing the pWIDE etc. symbols removed from editfns.c.

        * keyboard.h (num_input_events): Now uintmax_t.
        This is (very slightly) less likely to mess up due to wraparound.
        All uses changed.

        * buffer.c: Integer signedness fixes.
        (alloc_buffer_text, enlarge_buffer_text):
        Use ptrdiff_t rather than size_t when either will do, as we prefer
        signed integers.

        * alloc.c: Integer signedness and overflow fixes.
        Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
        (__malloc_size_t): Default to size_t, not to int.
        (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
        (Fgarbage_collect, mark_object_loop_halt, mark_object):
        Prefer ptrdiff_t to size_t when either would do, as we prefer
        signed integers.
        (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
        (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
        Now const.  Initialize with values that are in range even if char
        is signed.
        (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
        (xmalloc_put_size, xmalloc_get_size): New functions.  All uses changed.
        These functions do the right thing with sizes > 2**32.
        (check_depth): Now ptrdiff_t, not int.
        (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
        Adjust to new way of storing sizes.  Check for size overflow bugs
        in rest of code.
        (STRING_BYTES_MAX): Adjust to new overheads.  The old code was
        slightly wrong anyway, as it missed one instance of
        XMALLOC_OVERRUN_CHECK_OVERHEAD.
        (refill_memory_reserve): Omit needless cast to size_t.
        (mark_object_loop_halt): Mark as externally visible.

        * xselect.c: Integer signedness and overflow fixes.
        (Fx_register_dnd_atom, x_handle_dnd_message):
        Use ptrdiff_t, not size_t, since we prefer signed.
        (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
        * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
        x_dnd_atoms_size and x_dnd_atoms_length.

        * doprnt.c: Prefer signed to unsigned when either works.
        * eval.c (verror):
        * doprnt.c (doprnt):
        * lisp.h (doprnt):
        * xdisp.c (vmessage):
        Use ptrdiff_t, not size_t, when using or implementing doprnt,
        since the sizes cannot exceed ptrdiff_t bounds anyway, and we
        prefer signed arithmetic to avoid comparison confusion.
        * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
        but is a bit tricky.

        Assume freestanding C89 headers, string.h, stdlib.h.
        * data.c, doprnt.c, floatfns.c, print.c:
        Include float.h unconditionally.
        * gmalloc.c: Assume C89-at-least behavior for preprocessor,
        limits.h, stddef.h, string.h.  Use memset instead of 'flood'.
        * regex.c: Likewise for stddef.h, string.h.
        (ISASCII): Remove; can assume it returns 1 now.  All uses removed.
        * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
        * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
        (STDC_HEADERS): Remove obsolete defines.
        * sysdep.c: Include limits.h unconditionally.

        Assume support for memcmp, memcpy, memmove, memset.
        * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
        * regex.c (memcmp, memcpy):
        Remove; we assume C89 now.

        * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
        (__malloc_safe_bcopy): Remove; no longer needed.

        * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
        Use EMACS_INT, not EMACS_UINT, for sizes.  The code works equally
        well either way, and we prefer signed to unsigned.

2011-07-27  Lars Magne Ingebrigtsen  <larsi@gnus.org>

        * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
        closes the connection while we're reading (bug#9182).

2011-07-25  Jan Djärv  <jan.h.d@swipnet.se>

        * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
        are specified (Bug#9168).

2011-07-25  Paul Eggert  <eggert@cs.ucla.edu>

        * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
        Found by GCC static checking and --with-wide-int on a 32-bit host.

2011-07-25  Eli Zaretskii  <eliz@gnu.org>

        * xdisp.c (compute_display_string_pos): Fix logic of caching
        previous display string position.  Initialize cached_prev_pos to
        -1.  Fixes slow-down at the beginning of a buffer.

2011-07-24  Eli Zaretskii  <eliz@gnu.org>

        * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
        for attrs[LFACE_FONTSET_INDEX].

2011-07-23  Paul Eggert  <eggert@cs.ucla.edu>

        * xml.c (parse_region): Remove unused local
        that was recently introduced.

2011-07-23  Eli Zaretskii  <eliz@gnu.org>

        * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
        2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.

        * xdisp.c (move_it_in_display_line_to): Record the best matching
        position for TO_CHARPOS while scanning the line, and restore it on
        exit if none of the characters scanned was an exact match.
        Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
        when exact match is impossible due to invisible text, and the
        lines are truncated.

2011-07-23  Jan Djärv  <jan.h.d@swipnet.se>

        * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
        for OSX >= 10.7.

2011-07-22  Eli Zaretskii  <eliz@gnu.org>

        Fix a significant slow-down of cursor motion with C-n, C-p,
        C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
        auto-repeat under bidi redisplay in fontified buffers.
        * xdisp.c (compute_stop_pos_backwards): New function.
        (next_element_from_buffer): Call compute_stop_pos_backwards to
        find a suitable prev_stop when we find ourselves before
        base_level_stop.
        (reseat): Don't look for prev_stop, as that could mean a very long
        run.
        <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
        <cached_disp_overlay_modiff>: Cache for last found display string
        position.
        (compute_display_string_pos): Return the cached position if asked
        about the same buffer in the same area of character positions, and
        the buffer wasn't changed since the time the display string
        position was cached.

2011-07-22  Eli Zaretskii  <eliz@gnu.org>

        * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
        is an integer, which is important for empty lines.  (Bug#9149)

2011-07-22  Chong Yidong  <cyd@stupidchicken.com>

        * frame.c (Fmodify_frame_parameters): In tty case, update the
        default face if necessary (Bug#4238).

2011-07-21  Chong Yidong  <cyd@stupidchicken.com>

        * editfns.c (Fstring_to_char): No need to explain what a character
        is in the docstring (Bug#6576).

2011-07-20  Lars Magne Ingebrigtsen  <larsi@gnus.org>

        * xml.c (parse_region): Make sure we always return a tree.

2011-07-20  HAMANO Kiyoto  <khiker.mail@gmail.com>

        * xml.c (parse_region): If a document contains only comments,
        return that, too.

2011-07-20  Lars Magne Ingebrigtsen  <larsi@gnus.org>

        * xml.c (make_dom): Return comments, too.

2011-07-19  Paul Eggert  <eggert@cs.ucla.edu>

        Port to OpenBSD.
        See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
        and the surrounding thread.
        * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
        rather than fgets, and retry after EINTR.  Otherwise, 'emacs
        --batch -f byte-compile-file' fails on OpenBSD if an inactivity
        timer goes off.
        * s/openbsd.h (BROKEN_SIGIO): Define.
        * unexelf.c (unexec) [__OpenBSD__]:
        Don't update the .mdebug section of the Alpha COFF symbol table.

2011-07-19  Lars Magne Ingebrigtsen  <larsi@gnus.org>

        * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
        (bug#8460).

2011-07-18  Paul Eggert  <eggert@cs.ucla.edu>

        * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
        This fixes some race conditions on the permissions of any newly
        created file.

        * alloc.c (valid_pointer_p): Use pipe, not open.
        This fixes some permissions issues when debugging.

        * fileio.c (Fcopy_file): Adjust mode if fchown fails.  (Bug#9002)
        If fchown fails to set both uid and gid, try to set just gid,
        as that is sometimes allowed.  Adjust the file's mode to eliminate
        setuid or setgid bits that are inappropriate if fchown fails.

2011-07-18  Stefan Monnier  <monnier@iro.umontreal.ca>

        * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
        to compare Lisp_Objects.
        * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
        global_gnutls_log_level, don't mistake it for a Lisp_Object.
        (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.

2011-07-17  Andreas Schwab  <schwab@linux-m68k.org>

        * lread.c (read_integer): Unread even EOF character.
        (read1): Likewise.  Properly record start position of symbol.

        * lread.c (read1): Read `#:' as empty uninterned symbol if no
        symbol character follows.

2011-07-17  Paul Eggert  <eggert@cs.ucla.edu>

        * fileio.c (Fcopy_file): Pacify gcc re fchown.  (Bug#9002)
        This works around a problem with the previous change to Fcopy_file.
        Recent glibc declares fchown with __attribute__((warn_unused_result)),
        and without this change, GCC might complain about discarding
        fchown's return value.

2011-07-16  Juanma Barranquero  <lekktu@gmail.com>

        * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).

2011-07-16  Paul Eggert  <eggert@cs.ucla.edu>

        * fileio.c (Fcopy_file): Don't diagnose fchown failures.  (Bug#9002)

2011-07-16  Lars Magne Ingebrigtsen  <larsi@gnus.org>

        * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
        it's used from the C level.

        * process.c: Use the same condition for POLL_FOR_INPUT in both
        keyboard.c and process.c (bug#1858).

2011-07-09  Lawrence Mitchell  <wence@gmx.li>

        * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
        (Fgnutls_boot): Use it.

2011-07-15  Andreas Schwab  <schwab@linux-m68k.org>

        * doc.c (Fsubstitute_command_keys): Revert last change.

2011-07-15  Lars Magne Ingebrigtsen  <larsi@gnus.org>

        * doc.c (Fsubstitute_command_keys): Clarify that \= really only
        quotes the next character, and doesn't affect other longer
        sequences (bug#8935).

        * lread.c (syms_of_lread): Clarify that is isn't only
        `eval-buffer' and `eval-defun' that's affected by
        `lexical-binding' (bug#8460).

2011-07-15  Eli Zaretskii  <eliz@gnu.org>

        * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
        bidi redisplay when a line includes both an image and is truncated.

2011-07-14  Paul Eggert  <eggert@cs.ucla.edu>

        Fix minor problems found by static checking.
        * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
        (elsz): Now a signed constant, not a size_t var.  We prefer signed
        types to unsigned, to avoid integer comparison confusion.  Without
        this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
        "cannot optimize loop, the loop counter may overflow", a symptom
        of the confusion.
        * indent.c (Fvertical_motion): Mark locals as initialized.
        * xdisp.c (reseat_to_string): Fix pointer signedness issue.

2011-07-14  Lars Magne Ingebrigtsen  <larsi@gnus.org>

        * search.c (Fre_search_backward): Mention `case-fold-search' in
        all the re_search_* functions (bug#8138).

        * keyboard.c (Fopen_dribble_file): Document when the file is
        closed (bug#8056).

2011-07-14  Eli Zaretskii  <eliz@gnu.org>

        * bidi.c (bidi_dump_cached_states): Fix format of displaying
        bidi_cache_idx.

        Support bidi reordering of display and overlay strings.
        * xdisp.c (compute_display_string_pos)
        (compute_display_string_end): Accept additional argument STRING.
        (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
        (reseat_to_string): Initialize bidi_it->string.s and
        bidi_it->string.schars.
        (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
        NULL (avoids a crash in bidi_paragraph_init).
        Initialize itb.string.lstring.
        (init_iterator): Call bidi_init_it only of a valid
        buffer position was specified.  Initialize paragraph_embedding to
        L2R.
        (reseat_to_string): Initialize the bidi iterator.
        (display_string): If we need to ignore text properties of
        LISP_STRING, set IT->stop_charpos to IT->end_charpos.  (The
        original value of -1 will not work with bidi.)
        (compute_display_string_pos): First arg is now struct
        `text_pos *'; all callers changed.  Support display properties on
        Lisp strings.
        (compute_display_string_end): Support display properties on Lisp
        strings.
        (init_iterator, reseat_1, reseat_to_string): Initialize the
        string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
        when iterating on a string not from display properties).
        (compute_display_string_pos, compute_display_string_end):
        Fix calculation of the object to scan.  Fixes an error when using
        arrow keys.
        (next_element_from_buffer): Don't abort when IT_CHARPOS is before
        base_level_stop; instead, set base_level_stop to BEGV.
        Fixes crashes in vertical-motion.
        (next_element_from_buffer): Improve commentary for when
        the iterator is before prev_stop.
        (init_iterator): Initialize bidi_p from the default value of
        bidi-display-reordering, not from buffer-local value.  Use the
        buffer-local value only if initializing for buffer iteration.
        (handle_invisible_prop): Support invisible properties on strings
        that are being bidi-reordered.
        (set_iterator_to_next): Support bidi reordering of C strings and
        Lisp strings.
        (next_element_from_string): Support bidi reordering of Lisp
        strings.
        (handle_stop_backwards): Support Lisp strings as well.
        (display_string): Support display of R2L glyph rows.
        Use IT_STRING_CHARPOS when displaying from a Lisp string.
        (init_iterator): Don't initialize it->bidi_p for strings
        here.
        (reseat_to_string): Initialize it->bidi_p for strings here.
        (next_element_from_string, next_element_from_c_string)
        (next_element_from_buffer): Add xassert's for correspondence
        between IT's object being iterated and it->bidi_it.string
        structure.
        (face_before_or_after_it_pos): Support bidi iteration.
        (next_element_from_c_string): Handle the case of the first string
        character that is not the first one in the visual order.
        (get_visually_first_element): New function, refactored from common
        parts of next_element_from_buffer, next_element_from_string, and
        next_element_from_c_string.
        (tool_bar_lines_needed, redisplay_tool_bar)
        (display_menu_bar): Force left-to-right direction.  Add a FIXME
        comment for making that be controlled by a user option.
        (push_it, pop_it): Save and restore the state of the
        bidi iterator.  Save and restore the bidi_p flag.
        (pop_it): Iterate out of display property for string iteration as
        well.
        (iterate_out_of_display_property): Support iteration over strings.
        (handle_single_display_spec): Set up it->bidi_it for iteration
        over a display string, and call bidi_init_it.
        (handle_single_display_spec, next_overlay_string)
        (get_overlay_strings_1, push_display_prop): Set up the bidi
        iterator for displaying display or overlay strings.
        (forward_to_next_line_start): Don't use the shortcut if
        bidi-iterating.
        (back_to_previous_visible_line_start): If handle_display_prop
        pushed the iterator stack, restore the internal state of the bidi
        iterator by calling bidi_pop_it same number of times.
        (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
        and we are bidi-iterating, don't decrement the iterator position;
        instead, set the first_elt flag in the bidi iterator, to produce
        the same effect.
        (reseat_1): Remove redundant setting of string_from_display_prop_p.
        (push_display_prop): xassert that we are iterating a buffer.
        (push_it, pop_it): Save and restore paragraph_embedding member.

        correctly.  Don't assume unibyte strings are not bidi-reordered.
        (compute_display_string_pos)
        (compute_display_string_end): Fix handling the case of C string.
        (push_it, pop_it): Save and restore from_disp_prop_p.
        (handle_single_display_spec, push_display_prop): Set the
        from_disp_prop_p flag.
        (get_overlay_strings_1): Reset the from_disp_prop_p flag.
        (pop_it): Call iterate_out_of_display_property only if we are
        popping after iteration over a string that came from a display
        property.  Fix a typo in popping stretch info.  Add an assertion
        for verifying that the iterator position is in sync with the bidi
        iterator.
        (handle_single_display_spec, get_overlay_strings_1)
        (push_display_prop): Fix initialization of paragraph direction for
        string when that of the parent object is not yet determined.
        (reseat_1): Call bidi_init_it to resync the bidi
        iterator with IT's position.  (Bug#7616)
        (find_row_edges): If ROW->start.pos gives position
        smaller than min_pos, use it as ROW->minpos.  (Bug#7616)
        (handle_stop, back_to_previous_visible_line_start, reseat_1):
        Reset the from_disp_prop_p flag.

        (move_it_in_display_line_to, move_it_in_display_line)
        (move_it_to, move_it_vertically_backward, move_it_by_lines)
        (try_scrolling, redisplay_window, display_line): Use them when
        saving a temporary copy of the iterator and restoring it back.
        (back_to_previous_visible_line_start, reseat_1)
        (init_iterator): Empty the bidi cache "stack".
        (move_it_in_display_line_to): If iterator ended up at
        EOL, but we never saw any buffer positions smaller than
        to_charpos, return MOVE_POS_MATCH_OR_ZV.  Fixes vertical cursor
        motion in bidi-reordered lines.
        (move_it_in_display_line_to): Record prev_method and prev_pos
        immediately before the call to set_iterator_to_next.  Fixes cursor
        motion in bidi-reordered lines with stretch glyphs and strings
        displayed in margins.  (Bug#8133) (Bug#8867)
        Return MOVE_POS_MATCH_OR_ZV only if iterator position is past
        TO_CHARPOS.
        (pos_visible_p): Support positions in bidi-reordered lines.
        Save and restore bidi cache.

        Add comment.

2011-07-05  Paul Eggert  <eggert@cs.ucla.edu>

        Random fixes.  E.g., (random) never returned negative values.
        * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
        subseconds part to the entropy, as that's a bit more random.
        Prefer signed to unsigned, since the signedness doesn't matter and
        in general we prefer signed.  When given a limit, use a
        denominator equal to INTMASK + 1, not to VALMASK + 1, because the
        latter isn't right if USE_2_TAGS_FOR_INTS.
        * sysdep.c (get_random): Return a value in the range 0..INTMASK,
        not 0..VALMASK.  Don't discard "excess" bits that random () returns.

2011-07-04  Stefan Monnier  <monnier@iro.umontreal.ca>

        * textprop.c (text_property_stickiness):
        Obey Vtext_property_default_nonsticky.
        (syms_of_textprop): Add `display' to Vtext_property_default_nonsticky.
        * w32fns.c (syms_of_w32fns):
        * xfns.c (syms_of_xfns): Don't Add `display' since it's there by default.

2011-07-04  Paul Eggert  <eggert@cs.ucla.edu>

        * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
        This is more efficient than Ffile_directory_p and avoids a minor race.

2011-07-04  Lars Magne Ingebrigtsen  <larsi@gnus.org>

        * buffer.c (Foverlay_put): Say what the return value is
        (bug#7835).

        is a directory before asking whether to use the file name
        (bug#7564).
        (barf_or_query_if_file_exists): Make the "File is a directory"
        error be more correct.

        * fns.c (Frequire): Remove the mention of the .gz files, since
        that's installation-specific, but keep the mention of
        `get-load-suffixes'.

2011-07-04  Paul Eggert  <eggert@cs.ucla.edu>

        * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

2011-07-04  Juanma Barranquero  <lekktu@gmail.com>

        * gnutls.c (Fgnutls_boot): Don't mention :verify-error.
        (syms_of_gnutls): Remove duplicate DEFSYM for
        Qgnutls_bootprop_verify_hostname_error, an error for
        Qgnutls_bootprop_verify_error (which is no longer used).

        * eval.c (find_handler_clause): Remove parameters `sig' and `data',
        unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca.  All callers changed.
        Also (re)move comments that are misplaced or no longer relevant.

        * lread.c (syms_of_lread): Mention single symbols defined by
        `defvar' or `defconst' (bug#7154).

        * fns.c (Frequire): Mention .el.gz files (bug#7314).
        (Frequire): Mention get-load-suffixes.

        Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
        signed bit field, as this assumption is not portable and it makes
        Emacs crash when compiled with Sun C 5.8 on sparc.  Do not use
        "char debug_on_exit : 1" as this is not portable either; instead,
        use the portable "unsigned int debug_on_exit : 1".  Remove unused
        member evalargs.  Remove obsolete comments about cc bombing out.

2011-06-30  Jan Djärv  <jan.h.d@swipnet.se>

        New functions.
        (gsettings_client, gsettings_obj): New variables.

        (init_gsettings): New function.
        (xsettings_initialize): Call init_gsettings.
        (syms_of_xsettings): Initialize gsettings_client, gsettings_obj
        to NULL.

        clearly which files are directly included by each source file,
        and not through other includes.

        the overlay's window property doesn't match the current window.

        * window.c (Fwindow_vchild): Rename to Fwindow_top_child.
        (Fwindow_hchild): Rename to Fwindow_left_child.
        (Fwindow_next): Rename to Fwindow_next_sibling.

        * bidi.c (bidi_paragraph_init): Test for ZV_BYTE before calling
        bidi_at_paragraph_end, since fast_looking_at doesn't like to be

        * print.c (printchar, strout): Check for string overflow.
        (PRINTPREPARE, printchar, strout):
        Don't set size unless allocation succeeds.

        * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
        for sizes.  Check for string overflow more accurately.
        Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.

        * macros.c: Integer and buffer overflow fixes.
        * keyboard.h (struct keyboard.kbd_macro_bufsize):
        * macros.c (Fstart_kbd_macro, store_kbd_macro_char):

        * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.

        * lread.c: Integer overflow fixes.
        (read_integer): Radix is now EMACS_INT, not int,
        to improve quality of diagnostics for out-of-range radices.
        Calculate buffer size correctly for out-of-range radices.
        (read1): Check for integer overflow in radices, and in
        read-circle numbers.
        (read_escape): Avoid int overflow.
        (Fload, openp, read_buffer_size, read1)
        (substitute_object_recurse, read_vector, read_list, map_obarray):
        Use ptrdiff_t, not int, for sizes.
        (read1): Use EMACS_INT, not int, for sizes.
        Check for size overflow.

        * image.c (cache_image): Check for size arithmetic overflow.

2011-06-22  Paul Eggert  <eggert@cs.ucla.edu>

        Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
        The following patches are for when GLYPH_DEBUG && !XASSERT.
        * dispextern.h (trace_redisplay_p, dump_glyph_string):
        * dispnew.c (flush_stdout):
        * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
        Mark as externally visible.
        * dispnew.c (check_window_matrix_pointers): Now static.
        * dispnew.c (window_to_frame_vpos):
        * xfns.c (unwind_create_frame):
        * xterm.c (x_check_font): Remove unused local.
        * scroll.c (CHECK_BOUNDS):
        * xfaces.c (cache_fache): Rename local to avoid shadowing.
        * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
        * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
        (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
        (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
        Now static.
        (debug_method_add): Use va_list and vsprintf rather than relying
        on undefined behavior with wrong number of arguments.
        (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
        Don't assume ptrdiff_t and EMACS_INT are the same width as int.
        In this code, it's OK to assume C99 behavior for ptrdiff_t formats
        since we're not interested in debugging glyphs with old libraries.
        * xfaces.c (cache_face): Move debugging code earlier; this pacifies
        GCC 4.6.0's static checking.

2011-06-22  Paul Eggert  <eggert@cs.ucla.edu>

        * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
        (.bitmaps_last, struct x_output.icon_bitmap):
        Use ptrdiff_t, not int, for bitmap indexes.
        (x_allocate_bitmap_record): Check for size overflow.
        * dispextern.h, lisp.h: Adjust to API changes elsewhere.

        Use ptrdiff_t, not int, for overlay counts.
        * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
        * editfns.c (overlays_around, get_pos_property):

        * xdisp.c (next_overlay_change, note_mouse_highlight):
        * xfaces.c (face_at_buffer_position):
        * buffer.c (OVERLAY_COUNT_MAX): New macro.
        (overlays_at, overlays_in, sort_overlays, Foverlays_at)
        (Fnext_overlay_change, Fprevious_overlay_change)
        (mouse_face_overlay_overlaps, Foverlays_in):
        Use ptrdiff_t, not int, for sizes.
        (overlays_at, overlays_in): Check for size-calculation overflow.

        * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.

        * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
        (x_session_initialize): Do not assume string length fits in int.

        * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
        This is unlikely, but can occur if DPI is outlandish.

        * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
        * xselect.c (Fx_get_atom_name): Avoid need for strlen.

        * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
        * xrdb.c (magic_file_p, search_magic_path):
        Omit last arg SUFFIX; it was always 0.  All callers changed.
        (magic_file_p): Use ptrdiff_t, not int.  Check for size overflow.

        * xfont.c (xfont_match): Avoid need for strlen.

        * xfns.c: Don't assume strlen fits in int.
        (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.

        * xdisp.c (message_log_check_duplicate): Return intmax_t,
        not unsigned long, as we prefer signed integers.  All callers changed.
        Detect integer overflow in repeat count.
        (message_dolog): Don't assume print length fits in 39 bytes.
        (display_mode_element): Don't assume strlen fits in int.

        * lread.c (intern, intern_c_string):
        * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
        Don't assume string length fits in int.

        * keyboard.c (parse_tool_bar_item):
        * gtkutil.c (style_changed_cb): Avoid need for strlen.

        * font.c: Don't assume string length fits in int.
        (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):

        (font_intern_prop): Don't assume string length fits in int.
        Don't assume integer property fits in fixnum.
        * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.

        * filelock.c: Fix some buffer overrun and integer overflow issues.
        (get_boot_time): Don't assume gzip command string fits in 100 bytes.
        Reformulate so as not to need the command string.
        Invoke gzip -cd rather than gunzip, as it's more portable.
        (lock_info_type, lock_file_1, lock_file):
        Don't assume pid_t and time_t fit in unsigned long.
        (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
        (current_lock_owner): Prefer signed type for sizes.
        Use memcpy, not strncpy, where memcpy is what is really wanted.
        Don't assume (via atoi) that time_t and pid_t fit in int.
        Check for time_t and/or pid_t out of range, e.g., via a network share.
        Don't alloca where an auto var works fine.

        * fileio.c: Fix some integer overflow issues.
        (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
        Don't assume string length fits in int.
        (directory_file_name): Don't assume string length fits in long.
        (make_temp_name): Don't assume pid fits in int, or that its print
        length is less than 20.

        * data.c (Fsubr_name): Rewrite to avoid a strlen call.

        * coding.c (make_subsidiaries): Don't assume string length fits in int.

        * callproc.c (child_setup): Rewrite to avoid two strlen calls.

        * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
        We prefer signed integers, even for size calculations.

        * emacs.c: Don't assume string length fits in 'int'.
        (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
        (main): Don't invoke strlen when not needed.

        * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
        (XD_DEBUG_MESSAGE): Don't waste a byte.

        * callproc.c (getenv_internal_1, getenv_internal)
        (Fgetenv_internal):
        * buffer.c (init_buffer): Don't assume string length fits in 'int'.

        * lread.c (invalid_syntax): Omit length argument.
        All uses changed.  This doesn't fix a bug, but it simplifies the
        code away from its former Hollerith-constant appearance, and it's
        one less 'int' to worry about when looking at integer-overflow issues.
        (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.

        * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
        This didn't break anything, but it didn't help either.
        It's confusing to put a bogus integer in a place where the actual
        value does not matter.
        (LIST_END_P): Remove unused macro and its bogus comment.
        (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.

        * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
        This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
        implementation.
        (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
        We prefer signed types, and the value cannot exceed the EMACS_INT
        range anyway (because otherwise the length would not be representable).
        (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
        not EMACS_UINT and EMACS_INT, when converting pointer to integer.
        This avoids a GCC warning when WIDE_EMACS_INT.

        * indent.c (sane_tab_width): New function.
        (current_column, scan_for_column, Findent_to, position_indentation)
        (compute_motion): Use it.  This is just for clarity.
        (Fcompute_motion): Don't assume hscroll and tab offset fit in int.

        * image.c (xbm_image_p): Don't assume stated width, height fit in int.

        * lisp.h (lint_assume): New macro.
        * composite.c (composition_gstring_put_cache):
        * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.

        * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.

        Use much-faster test for byte-length change.
        Don't assume string byte-length fits in 'int'.
        Check that character arg fits in 'int'.
        (mapcar1): Declare byte as byte, for clarity.

        * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.

        * fns.c (concat): Catch string overflow earlier.
        Do not rely on integer wraparound.

        * dispextern.h (struct it.overlay_strings_charpos)
        (struct it.selective): Now EMACS_INT, not int.
        * xdisp.c (forward_to_next_line_start)
        (back_to_previous_visible_line_start)
        (reseat_at_next_visible_line_start, next_element_from_buffer):
        Don't arbitrarily truncate the value of 'selective' to int.

        * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.

        * composite.c: Don't truncate sizes to 'int'.
        (composition_gstring_p, composition_reseat_it)
        (composition_adjust_point): Use EMACS_INT, not int.
        (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
        not EMACS_UINT, for indexes.

        * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.

        * buffer.c: Include <verify.h>.
        (struct sortvec.priority, struct sortstr.priority):
        Now EMACS_INT, not int.
        (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
        (struct sortstr.size, record_overlay_string)
        (struct sortstrlist.size, struct sortlist.used):
        Don't truncate size to int.
        (record_overlay_string): Check for size-calculation overflow.
        (init_buffer_once): Check at compile-time, not run-time.

2011-06-22  Jim Meyering  <meyering@redhat.com>

        Don't leak an XBM-image-sized buffer
        * image.c (xbm_load): Free the image buffer after using it.

2011-06-21  Paul Eggert  <eggert@cs.ucla.edu>

        Port to Sun C.
        * composite.c (find_automatic_composition): Omit needless 'return 0;'
        that Sun C diagnosed.
        * fns.c (secure_hash): Fix pointer signedness issue.
        * intervals.c (static_offset_intervals): New function.
        (offset_intervals): Use it.

2011-06-21  Leo Liu  <sdl.web@gmail.com>

        * deps.mk (fns.o):
        * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
        sha512.h.

        * fns.c (secure_hash): Rename from crypto_hash_function and change
        the first arg to accept symbols.
        (Fsecure_hash): New primitive.
        (syms_of_fns): New symbols.

2011-06-20  Deniz Dogan  <deniz@dogan.se>

        * process.c (Fset_process_buffer): Clarify return value in
        docstring.

2011-06-18  Chong Yidong  <cyd@stupidchicken.com>

        * dispnew.c (add_window_display_history): Use BVAR.

        * xdisp.c (debug_method_add): Use BVAR.
        (check_window_end, dump_glyph_matrix, dump_glyph)
        (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.

        * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
        Likewise.

        * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
        check till after the cache is created in init_frame_faces.

2011-06-17  Stefan Monnier  <monnier@iro.umontreal.ca>

        * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.

2011-06-16  Paul Eggert  <eggert@cs.ucla.edu>

        * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
        Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
        hosts with pre-C99 libraries, because pD is wrongly defined to "t".

        Improve buffer-overflow checking (Bug#8873).
        * fileio.c (Finsert_file_contents):
        * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
        Remove the old (too-loose) buffer overflow checks.
        They weren't needed, since make_gap checks for buffer overflow.
        * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
        The old code merely checked for Emacs fixnum overflow, and relied
        on undefined (wraparound) behavior.  The new code avoids undefined
        behavior, and also checks for ptrdiff_t and/or size_t overflow.

        * editfns.c (Finsert_char): Don't dump core with very negative counts.
        Tune.  Don't use wider integers than needed.  Don't use alloca.
        Use a bigger 'string' buffer.  Rewrite to avoid 'n > 0' test.

        * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.

        * insdel.c, lisp.h (buffer_overflow): New function.
        (insert_from_buffer_1, replace_range, replace_range_2):
        * insdel.c (make_gap_larger):
        * editfns.c (Finsert_char):
        * fileio.c (Finsert_file_contents): Use it, to normalize wording.

        * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.

2011-06-15  Paul Eggert  <eggert@cs.ucla.edu>

        Integer overflow and signedness fixes (Bug#8873, Bug#8828).

        * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
        (GET_CCL_RANGE, IN_INT_RANGE): Use it.

        * fileio.c: Don't assume EMACS_INT fits in off_t.
        (emacs_lseek): New static function.
        (Finsert_file_contents, Fwrite_region): Use it.
        Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.

        * fns.c (Fload_average): Don't assume 100 * load average fits in int.

        * fns.c: Don't overflow int when computing a list length.
        * fns.c (QUIT_COUNT_HEURISTIC): New constant.
        (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
        truncation on 64-bit hosts.  Check for QUIT every
        QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
        faster and is responsive enough.
        (Flength): Report an error instead of overflowing an integer.
        (Fsafe_length): Return a float if the value is not representable
        as a fixnum.  This shouldn't happen except in contrived situations.
        (Fnthcdr, Fsort): Don't assume list length fits in int.
        (Fcopy_sequence): Don't assume vector length fits in int.

        * alloc.c: Check that resized vectors' lengths fit in fixnums.
        (header_size, word_size): New constants.
        (allocate_vectorlike): Don't check size overflow here.
        (allocate_vector): Check it here instead, since this is the only
        caller of allocate_vectorlike that could cause overflow.
        Check that the new vector's length is representable as a fixnum.

        * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
        The previous code was bogus.  For example, next_almost_prime (32)
        returned 39, which is undesirable as it is a multiple of 3; and
        next_almost_prime (24) returned 25, which is a multiple of 5 so
        why was the code bothering to check for multiples of 7?

        * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.

        * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.

        Variadic C functions now count arguments with ptrdiff_t.
        This partly undoes my 2011-03-30 change, which replaced int with size_t.
        Back then I didn't know that the Emacs coding style prefers signed int.
        Also, in the meantime I found a few more instances where arguments
        were being counted with int, which may truncate counts on 64-bit
        machines, or EMACS_INT, which may be unnecessarily wide.
        * lisp.h (struct Lisp_Subr.function.aMANY)
        (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
        Arg counts are now ptrdiff_t, not size_t.
        All variadic functions and their callers changed accordingly.
        (struct gcpro.nvars): Now size_t, not size_t.  All uses changed.
        * bytecode.c (exec_byte_code): Check maxdepth for overflow,
        to avoid potential buffer overrun.  Don't assume arg counts fit in 'int'.
        * callint.c (Fcall_interactively): Check arg count for overflow,
        to avoid potential buffer overrun.  Use signed char, not 'int',
        for 'varies' array, so that we needn't bother to check its size
        calculation for overflow.
        * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
        * eval.c (apply_lambda):
        * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
        (struct textprop_rec.argnum): Now ptrdiff_t, not int.  All uses changed.
        (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.

        * callint.c (Fcall_interactively): Don't use index var as event count.

        * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
        * mem-limits.h (SIZE): Remove; no longer used.

        * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.

        Remove unnecessary casts.
        * xterm.c (x_term_init):
        * xfns.c (x_set_border_pixel):
        * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
        These aren't needed now that we assume ANSI C.

        * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
        It's more likely to cause problems (due to unsigned overflow)
        than to cure them.

        * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.

        * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.

        * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.

        * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.

        * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.

        * lread.c (Fload): Don't compare a possibly-garbage time_t value.

        GLYPH_CODE_FACE returns EMACS_INT, not int.
        * dispextern.h (merge_faces):
        * xfaces.c (merge_faces):
        * xdisp.c (get_next_display_element, next_element_from_display_vector):
        Don't assume EMACS_INT fits in int.

        * character.h (CHAR_VALID_P): Remove unused parameter.
        * fontset.c, lisp.h, xdisp.c: All uses changed.

        * editfns.c (Ftranslate_region_internal): Omit redundant test.

        * fns.c (concat): Minor tuning based on overflow analysis.
        This doesn't fix any bugs.  Use int to hold character, instead
        of constantly refetching from Emacs object.  Use XFASTINT, not
        XINT, for value known to be a character.  Don't bother comparing
        a single byte to 0400, as it's always less.

        * floatfns.c (Fexpt):
        * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.

        * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
        for characters.

        * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.

        * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
        Without this fix, on a 64-bit host (aset S 0 4294967386) would
        incorrectly succeed when S was a string, because 4294967386 was
        truncated before it was used.

        * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
        Otherwise, an out-of-range integer could cause undefined behavior
        on a 64-bit host.

        * composite.c: Use int, not EMACS_INT, for characters.
        (fill_gstring_body, composition_compute_stop_pos): Use int, not
        EMACS_INT, for values that are known to be in character range.
        This doesn't fix any bugs but is the usual style inside Emacs and
        may generate better code on 32-bit machines.

        Make sure a 64-bit char is never passed to ENCODE_CHAR.
        This is for reasons similar to the recent CHAR_STRING fix.
        * charset.c (Fencode_char): Check that character arg is actually
        a character.  Pass an int to ENCODE_CHAR.
        * charset.h (ENCODE_CHAR): Verify that the character argument is no
        wider than 'int', as a compile-time check to prevent future regressions
        in this area.

        * character.c (char_string): Remove unnecessary casts.

        Make sure a 64-bit char is never passed to CHAR_STRING.
        Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
        by silently ignoring the top 32 bits, allowing some values
        that were far too large to be valid characters.
        * character.h: Include <verify.h>.
        (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
        arguments are no wider than unsigned, as a compile-time check
        to prevent future regressions in this area.
        * data.c (Faset):
        * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
        (Fsubst_char_in_region):
        * fns.c (concat):
        * xdisp.c (decode_mode_spec_coding):
        Adjust to CHAR_STRING's new requirement.
        * editfns.c (Finsert_char, Fsubst_char_in_region):
        * fns.c (concat): Check that character args are actually
        characters.  Without this test, these functions did the wrong
        thing with wildly out-of-range values on 64-bit hosts.

        Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
        These casts should not be needed on 32-bit hosts, either.
        * keyboard.c (read_char):
        * lread.c (Fload): Remove casts to unsigned.

        * lisp.h (UNSIGNED_CMP): New macro.
        This fixes comparison bugs on 64-bit hosts.
        (ASCII_CHAR_P): Use it.
        * casefiddle.c (casify_object):
        * character.h (ASCII_BYTE_P, CHAR_VALID_P)

        * composite.h (COMPOSITION_ENCODE_RULE_VALID):
        * dispextern.h (FACE_FROM_ID):
        * keyboard.c (read_char): Use UNSIGNED_CMP.

        * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
        not to EMACS_INT, to avoid GCC warning.

        * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.

        * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
        The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
        isn't needed on 32-bit machines.

        * buffer.c (Fgenerate_new_buffer_name):
        Use EMACS_INT for count, not int.
        (advance_to_char_boundary): Return EMACS_INT, not int.

        * alloc.c (make_save_value): Integer argument is now of type
        ptrdiff_t, not int.
        (mark_object): Use ptrdiff_t, not int.
        * lisp.h (pD): New macro.
        * print.c (print_object): Use it.

        * alloc.c: Use EMACS_INT, not int, to count objects.

        (total_free_conses, total_free_markers, total_free_symbols)
        (total_free_floats, total_floats, total_free_intervals)
        (total_intervals, total_strings, total_free_strings):
        Now EMACS_INT, not int.  All uses changed.
        (Fgarbage_collect): Compute overall total using a double, so that
        integer overflow is less likely to be a problem.  Check for overflow
        when converting back to an integer.
        (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
        (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
        These were 'int' variables that could overflow on 64-bit hosts;
        they were never used, so remove them instead of repairing them.
        (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
        (inhibit_garbage_collection): Set gc_cons_threshold to max value.
        Previously, this ceilinged at INT_MAX, but that doesn't work on
        64-bit machines.
        (allocate_pseudovector): Don't use EMACS_INT when int would do.

        * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
        (allocate_vectorlike): Check for ptrdiff_t overflow.
        (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
        when a (possibly-narrower) signed value would do just as well.
        We prefer using signed arithmetic, to avoid comparison confusion.

        * alloc.c: Catch some string size overflows that we were missing.
        (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
        for convenience in STRING_BYTES_MAX.
        (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
        The definition here is exact; the one in lisp.h was approximate.
        (allocate_string_data): Check for string overflow.  This catches
        some instances we weren't catching before.  Also, it catches
        size_t overflow on (unusual) hosts where SIZE_MAX <= min
        (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
        and ptrdiff_t and EMACS_INT are both 64 bits.

        * character.c, coding.c, doprnt.c, editfns.c, eval.c:
        All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
        * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.

        * character.c (string_escape_byte8): Fix nbytes/nchars typo.

        other_buffer.

        * window.c (temp_output_buffer_show): Call display_buffer with
        second argument Vtemp_buffer_show_specifiers and reset latter

        instead of using explicit *_CHAR codes.
        (bidi_resolve_explicit, bidi_resolve_weak):

        bidirectional text is supported only in multibyte buffers.
        (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use

        (display_prop_intangible_p): Reimplement to call
        handle_display_spec instead of single_display_spec_intangible_p.
        Accept 3 additional arguments needed by handle_display_spec.
        This fixes incorrect cursor motion across display property with complex

        jump to continue iteration.
        (reseat_1): Initialize bidi_it.disp_pos.

        * keyboard.c (adjust_point_for_property): Adjust the call to
        display_prop_intangible_p to its new signature.

        * gnutls.c: Use Emacs's memory allocators.
        Without this change, the gnutls library would invoke malloc etc.
        directly, which causes problems on non-SYNC_INPUT hosts, and which
        runs afoul of improving memory_full behavior.  (Bug#8761)
        (fn_gnutls_global_set_mem_functions): New macro or function pointer.
        (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
        xfree instead of the default malloc, realloc, free.
        (Fgnutls_boot): No need to check for memory allocation failure,

        Check for overflow in vector size calculations.
        * ccl.c (ccl_driver):
        Check for overflow when converting EMACS_INT to int.
        * fns.c, image.c: Remove unnecessary static decls that would otherwise
        need to be updated by these changes.
        * fns.c (make_hash_table, maybe_resize_hash_table):
        Check for integer overflow with large hash tables.
        (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
        Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
        (SXHASH_REDUCE): New macro.
        (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
        Use it instead of discarding useful hash info with large hash values.
        (sxhash_float): New function.
        (sxhash): Use it.  No more need for "& INTMASK" due to above changes.
        * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
        (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
        Rewrite to use FIXNUM_BITS, as this simplifies things.

        Adjust signatures to match updated version of code.
        (consing_since_gc): Now EMACS_INT, since a single hash table can
        use more than INT_MAX bytes.

        * dispnew.c (add_window_display_history): Use const for the string
        pointer.  Remove declaration, not needed.

2011-05-31  Paul Eggert  <eggert@cs.ucla.edu>

        Use 'inline', not 'INLINE'.
        <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
        * alloc.c, fontset.c (INLINE): Remove.
        * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
        * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
        * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
        * gmalloc.c (register_heapinfo): Use inline unconditionally.
        * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.

2011-05-31  Dan Nicolaescu  <dann@ics.uci.edu>

        Make it possible to run ./temacs.

        * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
        syms_of_callproc does the same thing.  Remove test for
        "initialized", do it in the caller.
        * emacs.c (main): Avoid calling set_initial_environment when dumping.

2011-05-31  Stefan Monnier  <monnier@iro.umontreal.ca>

        * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
        (read_minibuf): Use get_minibuffer.
        (syms_of_minibuf): Use DEFSYM.
        (Qmetadata): New var.
        * data.c (Qbuffer): Don't make it static.
        (syms_of_data): Use DEFSYM.

2011-05-31  Paul Eggert  <eggert@cs.ucla.edu>

        * ccl.c (CCL_CODE_RANGE): Allow negative numbers.  (Bug#8751)
        (CCL_CODE_MIN): New macro.

2011-05-30  Paul Eggert  <eggert@cs.ucla.edu>

        * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.

        * eval.c (Qdebug): Now static.
        * lisp.h (Qdebug): Remove decl.  This reverts a part of the
        2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
        2011-04-14T06:48:41Z!eggert@cs.ucla.edu.

2011-05-29  Chong Yidong  <cyd@stupidchicken.com>

        * image.c: Various fixes to ImageMagick code comments.
        (Fimagemagick_types): Doc fix.

2011-05-29  Paul Eggert  <eggert@cs.ucla.edu>

        Minor fixes prompted by GCC 4.6.0 warnings.

        * xselect.c (converted_selections, conversion_fail_tag): Now static.

        * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
        (x_clipboard_manager_save_all): Move extern decl to ...
        * xterm.h: ... here, so that it can be checked for consistency.

2011-05-29  Chong Yidong  <cyd@stupidchicken.com>

        * xselect.c (x_clipboard_manager_save_frame)
        (x_clipboard_manager_save_all): New functions.
        (Fx_clipboard_manager_save): Lisp function deleted.

        * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
        * frame.c (delete_frame): Call x_clipboard_manager_save_frame.

        * xterm.h: Update prototype.

2011-05-28  William Xu  <william.xwl@gmail.com>

        * nsterm.m (ns_term_shutdown): Synchronize user defaults before
        exiting (Bug#8239).

2011-05-28  Jim Meyering  <meyering@redhat.com>

        Avoid a sign-extension bug in crypto_hash_function.
        * fns.c (to_uchar): Define.
        (crypto_hash_function): Use it to convert some newly-signed
        variables to unsigned, to avoid sign-extension bugs.  For example,
        without this change, (md5 "truc") would evaluate to
        45723a2aff78ff4fff7fff1114760e62 rather than the expected
        45723a2af3788c4ff17f8d1114760e62.  Reported by Antoine Levitt in
        https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.

2011-05-27  Paul Eggert  <eggert@cs.ucla.edu>

        Integer overflow fixes.

        * dbusbind.c: Serial number integer overflow fixes.
        (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
        (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
        to hold a serial number that is too large for a fixnum.
        (Fdbus_method_return_internal, Fdbus_method_error_internal):
        Check for serial numbers out of range.  Decode any serial number
        that was so large that it became a float.  (Bug#8722)

        * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
        (Fdbus_call_method, Fdbus_call_method_asynchronously):
        Use XFASTINT rather than XUINT when numbers are nonnegative.
        (xd_append_arg, Fdbus_method_return_internal):
        (Fdbus_method_error_internal): Likewise.  Also, for unsigned
        arguments, check that Lisp number is nonnegative, rather than
        silently wrapping negative numbers around.  (Bug#8722)
        (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
        (Bug#8722)

        * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.

        * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.

        ccl: Add integer overflow checks.
        * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
        (IN_INT_RANGE): New macros.
        (ccl_driver): Use them to check for integer overflow when
        decoding a CCL program.  Many of the new checks are whether XINT (x)
        fits in int; it doesn't always, on 64-bit hosts.  The new version
        doesn't catch all possible integer overflows, but it's an
        improvement.  (Bug#8719)

        * alloc.c (make_event_array): Use XINT, not XUINT.
        There's no need for unsigned here.

        * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
        This follows up to the 2011-05-06 change that substituted uintptr_t
        for EMACS_INT.  This case wasn't caught back then.

        Rework Fformat to avoid integer overflow issues.
        * editfns.c: Include <float.h> unconditionally, as it's everywhere
        now (part of C89).  Include <verify.h>.
        (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
        (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
        (Fformat): Avoid the prepass trying to compute sizes; it was only
        approximate and thus did not catch overflow reliably.  Instead, walk
        through the format just once, formatting and computing sizes as we go,
        checking for integer overflow at every step, and allocating a larger
        buffer as needed.  Keep track separately whether the format is
        multibyte.  Keep only the most-recently calculated precision, rather
        than them all.  Record whether each argument has been converted to
        string.  Use EMACS_INT, not int, for byte and char and arg counts.
        Support field widths and precisions larger than INT_MAX.  Avoid
        sprintf's undefined behavior with conversion specifications such as %#d
        and %.0c.  Fix bug with strchr succeeding on '\0' when looking for
        flags.  Fix bug with (format "%c" 256.0).  Avoid integer overflow when
        formatting out-of-range floating point numbers with int
        formats.  (Bug#8668)

        * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.

        * data.c: Avoid integer truncation in expressions involving floats.
        * data.c: Include <intprops.h>.
        (arith_driver): When there's an integer overflow in an expression
        involving floating point, convert the integers to floating point
        so that the resulting value does not suffer from catastrophic
        integer truncation.  For example, on a 64-bit host (* 4
        most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
        Do not rely on undefined behavior after integer overflow.

        merge count_size_as_multibyte, parse_str_to_multibyte
        * character.c, character.h (count_size_as_multibyte):
        Rename from parse_str_to_multibyte; all uses changed.
        Check for integer overflow.
        * insdel.c, lisp.h (count_size_as_multibyte): Remove,
        since it's now a duplicate of the other.  This is more of
        a character than a buffer op, so better that it's in character.c.
        * fns.c, print.c: Adjust to above changes.

2011-05-27  Stefan Monnier  <monnier@iro.umontreal.ca>

        * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.

2011-05-27  Paul Eggert  <eggert@cs.ucla.edu>

        * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
        (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
        (x_clipboard_manager_save): Now static.
        (Fx_clipboard_manager_save): Rename local to avoid shadowing.

        * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
        (crypto_hash_function): Now static.
        Fix pointer signedness problems.  Avoid unnecessary initializations.

2011-05-27  Chong Yidong  <cyd@stupidchicken.com>

        * termhooks.h (Vselection_alist): Make it terminal-local.

        * terminal.c (create_terminal): Initialize it.

        * xselect.c: Support for clipboard managers.
        (Vselection_alist): Move to termhooks.h as terminal-local var.
        (LOCAL_SELECTION): New macro.
        (x_atom_to_symbol): Handle x_display_info_for_display fail case.
        (symbol_to_x_atom): Remove gratuitous arg.
        (x_handle_selection_request, lisp_data_to_selection_data)
        (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
        (x_own_selection, x_get_local_selection, x_convert_selection):
        New arg, specifying work frame.  Use terminal-local Vselection_alist.
        (some_frame_on_display): Delete unused function.
        (Fx_own_selection_internal, Fx_get_selection_internal)
        (Fx_disown_selection_internal, Fx_selection_owner_p)
        (Fx_selection_exists_p): New optional frame arg.
        (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
        (x_handle_selection_clear): Don't treat other terminals with the
        same keyboard specially.  Use the terminal-local Vselection_alist.
        (x_clear_frame_selections): Use Frun_hook_with_args.

        * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.

        * xterm.h: Add support for those atoms.

2011-05-26  Chong Yidong  <cyd@stupidchicken.com>

        * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
        (converted_selections, conversion_fail_tag): New global variables.
        (x_selection_request_lisp_error): Free the above.
        (x_get_local_selection): Remove unnecessary code.
        (x_reply_selection_request): Args changed; handle arbitrary array
        of converted selections stored in converted_selections.
        Separate the XChangeProperty and SelectionNotify steps.
        (x_handle_selection_request): Rewrite to handle MULTIPLE target.
        (x_convert_selection): New function.
        (x_handle_selection_event): Simplify.
        (x_get_foreign_selection): Don't ignore incoming requests while
        waiting for an answer; this will fail when we implement
        SAVE_TARGETS, and seems unnecessary anyway.
        (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
        (Vx_sent_selection_functions): Doc fix.

2011-05-26  Leo Liu  <sdl.web@gmail.com>

        * editfns.c (Ftranspose_regions): Allow empty regions.  (Bug#8699)

2011-05-25  YAMAMOTO Mitsuharu  <mituharu@math.s.chiba-u.ac.jp>

        * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.

        * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
        for fringe update if it has periodic bitmap.
        (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
        and fringe_bitmap_periodic_p.

        * fringe.c (get_fringe_bitmap_data): New function.
        (draw_fringe_bitmap_1, update_window_fringes): Use it.
        (update_window_fringes): Record periodicity of fringe bitmap in glyph
        row.  Mark glyph row for fringe update if periodicity changed.

        * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
        for fringe update unless it has periodic bitmap.

2011-05-25  Kenichi Handa  <handa@m17n.org>

        * xdisp.c (get_next_display_element): Set correct it->face_id for
        a static composition.

2011-05-24  Leo Liu  <sdl.web@gmail.com>

        * deps.mk (fns.o):
        * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.

        * fns.c (crypto_hash_function, Fsha1): New function.
        (Fmd5): Use crypto_hash_function.
        (syms_of_fns): Add Ssha1.

2011-05-22  Paul Eggert  <eggert@cs.ucla.edu>

        * gnutls.c: Remove unused macros.
        (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
        (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
        Remove macros that are defined and never used.
        Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).

2011-05-22  Chong Yidong  <cyd@stupidchicken.com>

        * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
        (Fx_get_selection_internal): Minor cleanup.
        (Fx_own_selection_internal): Rename arguments for consistency with
        select.el.

2011-05-22  Paul Eggert  <eggert@cs.ucla.edu>

        * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.

2011-05-22  Chong Yidong  <cyd@stupidchicken.com>

        * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.

2011-05-21  YAMAMOTO Mitsuharu  <mituharu@math.s.chiba-u.ac.jp>

        * dispnew.c (scrolling_window): Don't exclude the case that the
        last enabled row in the desired matrix touches the bottom boundary.

2011-05-21  Glenn Morris  <rgm@gnu.org>

        * Makefile.in ($(etc)/DOC): Make second command line even shorter.
        (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
        and add some more files.

2011-05-20  Eli Zaretskii  <eliz@gnu.org>

        * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
        report_file_error introduced by the change from 2011-05-07.

2011-05-20  Paul Eggert  <eggert@cs.ucla.edu>

        * systime.h (Time): Define only if emacs is defined.
        This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
        where the include path doesn't have X11/X.h by default.  See
        <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.

2011-05-20  Kenichi Handa  <handa@m17n.org>

        * composite.c (find_automatic_composition): Fix previous change.

2011-05-20  Glenn Morris  <rgm@gnu.org>

        * lisp.mk: New file, split from Makefile.in.
        * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
        (shortlisp): Remove.
        ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.

2011-05-19  Glenn Morris  <rgm@gnu.org>

        * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
        (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
        (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
        (lisp): Set the order to that of loadup.el.
        (shortlisp): Make it a copy of $lisp.
        (SOME_MACHINE_LISP): Remove.
        ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
        Use just $shortlisp, not $SOME_MACHINE_LISP too.

2011-05-18  Kenichi Handa  <handa@m17n.org>

        * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
        (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
        (find_automatic_composition): Mostly rewrite for efficiency.

2011-05-18  Juanma Barranquero  <lekktu@gmail.com>

        * makefile.w32-in: Update dependencies.

2011-05-18  Christoph Scholtes  <cschol2112@googlemail.com>

        * menu.c: Include limits.h (fixes the MS-Windows build broken by
        2011-06-18T18:49:19Z!cyd@stupidchicken.com).

2011-05-18  Paul Eggert  <eggert@cs.ucla.edu>

        Fix some integer overflow issues, such as string length overflow.

        * insdel.c (count_size_as_multibyte): Check for string overflow.

        * character.c (lisp_string_width): Check for string overflow.
        Use EMACS_INT, not int, for string indexes and lengths; in
        particular, 2nd arg is now EMACS_INT, not int.  Do not crash if
        the resulting string length overflows an EMACS_INT; instead,
        report a string overflow if no precision given.  When checking for
        precision exhaustion, use a check that cannot possibly have
        integer overflow.  (Bug#8675)
        * character.h (lisp_string_width): Adjust to new signature.

        * alloc.c (string_overflow): New function.
        (Fmake_string): Use it.  This doesn't change behavior, but saves
        a few bytes and will simplify future changes.
        * character.c (string_escape_byte8): Likewise.
        * lisp.h (string_overflow): New decl.

        Fixups, following up to the user-interface timestamp change.
        * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
        for UI timestamps, instead of unsigned long.
        * msdos.c (mouse_get_pos): Likewise.
        * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
        * w32gui.h (Time): Define by including "systime.h" rather than by
        declaring it ourselves.  (Bug#8664)

        * dispextern.h (struct image): Don't assume time_t <= unsigned long.
        * image.c (clear_image_cache): Likewise.

        * term.c (term_mouse_position): Don't assume time_t wraparound.

        Be more systematic about user-interface timestamps.
        Before, the code sometimes used 'Time', sometimes 'unsigned long',
        and sometimes 'EMACS_UINT', to represent these timestamps.
        This change causes it to use 'Time' uniformly, as that's what X uses.
        This makes the code easier to follow, and makes it easier to catch
        integer overflow bugs such as Bug#8664.
        * frame.c (Fmouse_position, Fmouse_pixel_position):
        Use Time, not unsigned long, for user-interface timestamps.
        * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
        (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
        * keyboard.h (last_event_timestamp): Likewise.
        * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
        * menu.h (xmenu_show): Likewise.
        * term.c (term_mouse_position): Likewise.
        * termhooks.h (struct input_event.timestamp): Likewise.
        (struct terminal.mouse_position_hook): Likewise.
        * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
        * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
        * systime.h (Time): New decl.  Pull it in from <X11/X.h> if
        HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
        what it was before.
        * menu.h, termhooks.h: Include "systime.h", for Time.

        * keyboard.c (make_lispy_event): Fix problem in integer overflow.
        Don't assume that the difference between two unsigned long values
        can fit into an integer.  At this point, we know button_down_time
        <= event->timestamp, so the difference must be nonnegative, so
        there's no need to cast the result if double-click-time is
        nonnegative, as it should be; check that it's nonnegative, just in
        case.  This bug is triggered when events are more than 2**31 ms
        apart (about 25 days).  (Bug#8664)

        * xselect.c (last_event_timestamp): Remove duplicate decl.
        (x_own_selection): Remove needless cast to unsigned long.

        * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
        that always fit in int.  Use a sentinel instead of a counter, to
        avoid a temp and to allay GCC's concerns about possible int overflow.
        * frame.h (struct frame): Use int for menu_bar_items_used
        instead of EMACS_INT, since it always fits in int.

        * menu.c (grow_menu_items): Check for int overflow.

        * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.

        * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
        Before, the code was not consistent.  These values cannot exceed
        2**31 - 1 so there's no need to make them unsigned.
        (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
        (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
        (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
        as modifiers.
        * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.

        * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
        (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
        Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
        presumably because the widths might not match.

        * window.c (size_window): Avoid needless test at loop start.

2011-05-18  Courtney Bane  <emacs-bugs-7626@cbane.org>  (tiny change)

        * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).

2011-05-12  Drew Adams  <drew.adams@oracle.com>

        * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).

2011-05-12  YAMAMOTO Mitsuharu  <mituharu@math.s.chiba-u.ac.jp>

        * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
        `width' to `bar_area_x' and `bar_area_width', respectively.
        (x_scroll_run): Take account of fringe background extension.

        * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
        Rename local vars `left' and `width' to `bar_area_x' and
        `bar_area_width', respectively.
        (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
        background extension.

2011-05-10  Jim Meyering  <meyering@redhat.com>

        * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".

2011-05-10  Juanma Barranquero  <lekktu@gmail.com>

        * image.c (Finit_image_library): Return t for built-in image types,
        like pbm and xbm.  (Bug#8640)

2011-05-09  Andreas Schwab  <schwab@linux-m68k.org>

        * w32menu.c (set_frame_menubar): Fix submenu allocation.

2011-05-07  Eli Zaretskii  <eliz@gnu.org>

        * w32console.c (Fset_screen_color): Doc fix.
        (Fget_screen_color): New function.
        (syms_of_ntterm): Defsubr it.

        * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
        unlink the temporary file if Fcall_process didn't create it in the
        first place.
        (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
        child process will be redirected to a file specified with `:file'.
        Don't try to re-open tempfile in that case, and set fd[0] to -1 as
        cue to call_process_cleanup not to close that handle.

2011-05-07  Ben Key  <bkey76@gmail.com>

        * makefile.w32-in: The bootstrap-temacs rule now makes use of
        one of two shell specific rules, either bootstrap-temacs-CMD or
        bootstrap-temacs-SH.  The bootstrap-temacs-SH rule is identical
        to the previous implementation of the bootstrap-temacs rule.
        The bootstrap-temacs-CMD rule is similar to the previous
        implementation of the bootstrap-temacs rule except that it
        makes use of the ESC_CFLAGS variable instead of the CFLAGS
        variable.

        These changes, along with some changes to nt/configure.bat,
        nt/gmake.defs, and nt/nmake.defs, are required to extend my
        earlier fix to add support for --cflags and --ldflags options
        that include quotes so that it works whether make uses cmd or
        sh as the shell.

2011-05-06  Michael Albinus  <michael.albinus@gmx.de>

        * dbusbind.c (QCdbus_type_unix_fd): Declare static.
        (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
        is a constant.
        (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
        a string.  Handle both cases.
        (Fdbus_call_method_asynchronously, Fdbus_register_signal)
        (Fdbus_register_method): Use Qinvalid_function.

2011-05-06  Juanma Barranquero  <lekktu@gmail.com>

        * makefile.w32-in: Update dependencies.
        (LISP_H): Add inttypes.h and stdin.h.
        (PROCESS_H): Add unistd.h.

2011-05-06  Eli Zaretskii  <eliz@gnu.org>

        * lread.c: Include limits.h (fixes the MS-Windows build broken by
        2011-05-06T07:13:19Z!eggert@cs.ucla.edu).

2011-05-06  Paul Eggert  <eggert@cs.ucla.edu>

        * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.

        * term.c (vfatal): Remove stray call to va_end.
        It's not needed and the C Standard doesn't allow it here anyway.

        Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
        * eval.c (verror): doprnt a copy of ap, not the original.  (Bug#8545)

        * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
        bytes.

        * term.c: Don't include <stdarg.h>, as <lisp.h> does that.

        * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.

        * process.c (Fformat_network_address): Fix typo: args2 -> *args2.

        * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).

        * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).

        * charset.h (struct charset.code_space): Now has 15 elements, not 16.
        * charset.c (Fdefine_charset_internal): Don't initialize
        charset.code_space[15].  The value was garbage, on hosts with
        32-bit int (Bug#8600).

        * lread.c (read_integer): Be more consistent with string-to-number.
        Use string_to_number to do the actual conversion; this avoids
        rounding errors and fixes some other screwups.  Without this fix,
        for example, #x1fffffffffffffff was misread as -2305843009213693952.
        (digit_to_number): Move earlier, for benefit of read_integer.
        Return -1 if the digit is out of range for the base, -2 if it is
        not a digit in any supported base.  (Bug#8602)

        * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".

        * dispnew.c (scrolling_window): Return 1 if we scrolled,
        to match comment at start of function.  This also removes a
        GCC warning about overflow in a 32+64-bit port.

        * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.

        * dbusbind.c: Do not use XPNTR on a value that may be an integer.
        Reported by Stefan Monnier in
        <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
        (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
        Use SYMBOLP-guarded XSYMBOL, not XPNTR.

        * lisp.h (EMACS_INTPTR): Remove.  All uses changed to intptr_t.
        (EMACS_UINTPTR): Likewise, with uintptr_t.

        * lisp.h: Prefer 64-bit EMACS_INT if available.
        (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
        on 32-bit hosts that have 64-bit int, so that they can access
        large files.
        However, temporarily disable this change unless the temporary
        symbol WIDE_EMACS_INT is defined.

        * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.

        Prefer intptr_t/uintptr_t for integers the same widths as pointers.
        This removes an assumption that EMACS_INT and long are the same
        width as pointers.  The assumption is true for Emacs porting targets
        now, but we want to make other targets possible.
        * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
        (EMACS_INTPTR, EMACS_UINTPTR): New macros.
        In the rest of the code, change types of integers that hold casted
        pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
        replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
        (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
        (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
        No need to cast type when ORing.
        (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
        * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
        * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
        assume EMACS_INT is the same width as char *.
        * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
        (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
        Remove no-longer-needed casts.
        (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
        (xg_tool_bar_help_callback, xg_make_tool_item):
        Use EMACS_INTPTR to hold an integer
        that will be cast to void *; this can avoid a GCC warning
        if EMACS_INT is not the same width as void *.
        * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
        * xdisp.c (display_echo_area_1, resize_mini_window_1):
        (current_message_1, set_message_1):
        Use a local to convert to proper width without a cast.
        * xmenu.c (dialog_selection_callback): Likewise.

        * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
        Also, don't assume VALBITS / RAND_BITS is less than 5,
        and don't rely on undefined behavior when shifting a 1 left into
        the sign bit.
        * lisp.h (get_random): Change signature to match.

        * lread.c (hash_string): Use size_t, not int, for hash computation.
        Normally we prefer signed values; but hashing is special, because
        it's better to use unsigned division on hash table sizes so that
        the remainder is nonnegative.  Also, size_t is the natural width
        for hashing into memory.  The previous code used 'int', which doesn't
        retain enough info to hash well into very large tables.
        (oblookup, oblookup_last_bucket_number, Funintern): Likewise.

        * dbusbind.c: Don't possibly lose pointer info when converting.
        (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
        Use XPNTR rather than XHASH, so that the high-order bits of
        the pointer aren't lost when converting through void *.

        * eval.c (Fautoload): Don't double-shift a pointer.

        * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.

2011-05-06  Juanma Barranquero  <lekktu@gmail.com>

        * gnutls.c (DEF_GNUTLS_FN):
        * image.c (DEF_IMGLIB_FN): Make function pointers static.

2011-05-05  Andreas Schwab  <schwab@linux-m68k.org>

        * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
        marker.  (Bug#8610)

        * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to

2011-05-05  Juanma Barranquero  <lekktu@gmail.com>

        * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
        Update dependencies.

2011-05-04  Juanma Barranquero  <lekktu@gmail.com>

        * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
        * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
        Remove unused parameter `fildes'.
        * process.c (read_process_output, send_process): Don't pass it.

2011-05-04  Juanma Barranquero  <lekktu@gmail.com>

        Fix previous change: the library cache is defined in w32.c.
        * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
        (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".

2011-05-04  Juanma Barranquero  <lekktu@gmail.com>

        Implement dynamic loading of GnuTLS on Windows.

        * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
        (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
        (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
        Declare.

        * gnutls.c (Qgnutls_dll): Define.

        (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
        Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.

        (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
        (Fgnutls_available_p): New function.

        its filename in the :loaded-from property of the library id.
        (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
        Initialize and staticpro them.
        (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.

        * process.c: Include lisp.h before w32.h, not after.
        (wait_reading_process_output): Call emacs_gnutls_record_check_pending
        instead of gnutls_record_check_pending.

        * callproc.c, emacs.c: Include lisp.h before w32.h, not after.

2011-05-04  Teodor Zlatanov  <tzz@lifelogs.com>

        * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
        instead of :keyfiles.  Give GnuTLS the keylist and the CRL lists
        as passed in.

        (Qgnutls_bootprop_verify_error, Qgnutls_bootprop_verify_hostname_error)
        (Qgnutls_bootprop_callbacks_verify): Make static.

2011-05-01  Andreas Schwab  <schwab@linux-m68k.org>

        * callproc.c: Indentation fixup.

        * sysdep.c (wait_for_termination_1): Make static.
        (wait_for_termination, interruptible_wait_for_termination):
        Move after wait_for_termination_1.

2011-05-01  Lars Magne Ingebrigtsen  <larsi@gnus.org>

        * sysdep.c (interruptible_wait_for_termination): New function
        which is like wait_for_termination, but allows keyboard
        interruptions.

        * callproc.c (Fcall_process): Add (:file "file") as an option for
        the STDOUT buffer.
        (Fcall_process_region): Ditto.

2011-04-30  Eli Zaretskii  <eliz@gnu.org>

        * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
        rather than `XVECTOR (FOO)->size'.

        * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
        inttypes.h, as a gnulib replacement is used if it not available in
        system headers.

2011-04-21  Eli Zaretskii  <eliz@gnu.org>

        Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.

        will grow beyond MOST_POSITIVE_FIXNUM.
        (decode_coding_emacs_mule): Abort if there isn't enough place in

        space for up to 2 characters produced in a loop.
        (decode_coding_iso_2022): Abort if there isn't enough place in
        charbuf for the composition carryover bytes.

        [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
        %llo or %llx format is passed.  (Bug#8545)

        * window.c (window_scroll_line_based): Use a marker instead of
        simple variables to record original value of point.  (Bug#7952)

        * doprnt.c (doprnt): Fix the case where a multibyte sequence
        produced by %s or %c overflows available buffer space.  (Bug#8545)

2011-04-28  Paul Eggert  <eggert@cs.ucla.edu>

        * doprnt.c (doprnt): Don't return value smaller than the buffer
        size if the message was truncated.  (Bug#8545).

2011-04-28  Juanma Barranquero  <lekktu@gmail.com>

        * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
        (Fx_window_property): #if-0 the whole functions, not just the bodies.

2011-04-27  Paul Eggert  <eggert@cs.ucla.edu>

        * doprnt.c (doprnt): Support "ll" length modifier, for long long.

2011-04-27  Juanma Barranquero  <lekktu@gmail.com>

        * makefile.w32-in: Update dependencies.

2011-04-27  Eli Zaretskii  <eliz@gnu.org>

        Improve `doprnt' and its usage.  (Bug#8545)
        * doprnt.c (doprnt): Make sure `format' is never accessed beyond
        `format_end'.  Remove support for %l as a conversion specifier.
        Don't use xrealloc.  Improve diagnostics when the %l size modifier
        is used.  Update the commentary.

        * eval.c (verror): Simplify calculation of size_t.

        * coding.c (Ffind_operation_coding_system): Fix diagnostic error
        messages.

2011-04-27  Yoshiaki Kasahara  <kasahara@nc.kyushu-u.ac.jp>  (tiny change)

        * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
        change.

2011-04-27  Paul Eggert  <eggert@cs.ucla.edu>

        * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
        This makes this file independent of the recent pseudovector change.

2011-04-26  Paul Eggert  <eggert@cs.ucla.edu>

        * keyboard.c (handle_user_signal): Fix pointer signedness problem.

        * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
        (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
        Remove unused local.
        (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.

        * lisp.h: Fix a problem with aliasing and vector headers.  (Bug#8546)
        GCC 4.6.0 optimizes based on type-based alias analysis.
        For example, if b is of type struct buffer * and v of type struct
        Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
        != &v->size, and therefore "v->size = 1; b->size = 2; return
        v->size;" must therefore return 1.  This assumption is incorrect
        for Emacs, since it type-puns struct Lisp_Vector * with many other
        types.  To fix this problem, this patch adds a new type struct
        vectorlike_header that documents the constraints on layout of vectors
        and pseudovectors, and helps optimizing compilers not get fooled
        by Emacs's type punning.  It also adds the macros XSETTYPED_PVECTYPE
        XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
        * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
        the size member.
        (XSETPVECTYPE): Rewrite in terms of new macro.
        (XSETPVECTYPESIZE): New macro, specifying both type and size.
        This is a bit clearer, and further avoids the possibility of
        undesirable aliasing.
        (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
        (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
        (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
        since Lisp_Subr is a special case (no "next" field).
        (ASIZE): Now uses header.size rather than size.
        All previous uses of XVECTOR (foo)->size replaced to use this macro,
        to avoid the hassle of writing XVECTOR (foo)->header.size.
        (struct vectorlike_header): New type.
        (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
        object, to help avoid aliasing.
        (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
        (SUBRP): Likewise, since Lisp_Subr is a special case.
        * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
        (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
        (struct Lisp_Hash_Table): Combine first two members into a single
        struct vectorlike_header member.  All uses of "size" and "next" members
        changed to be "header.size" and "header.next".
        * buffer.h (struct buffer): Likewise.
        * font.h (struct font_spec, struct font_entity, struct font): Likewise.
        * frame.h (struct frame): Likewise.
        * process.h (struct Lisp_Process): Likewise.
        * termhooks.h (struct terminal): Likewise.
        * window.c (struct save_window_data, struct saved_window): Likewise.
        * window.h (struct window): Likewise.
        * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
        Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
        * buffer.c (init_buffer_once): Likewise.
        * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
        special case.
        * process.c (Fformat_network_address): Use local var for size,
        for brevity.

        * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.

        Make the Lisp reader and string-to-float more consistent (Bug#8525)
        * data.c (atof): Remove decl; no longer used or needed.
        (digit_to_number): Move to lread.c.
        (Fstring_to_number): Use new string_to_number function, to be
        consistent with how the Lisp reader treats infinities and NaNs.
        Do not assume that floating-point numbers represent EMACS_INT
        without losing information; this is not true on most 64-bit hosts.
        Avoid double-rounding errors, by insisting on integers when
        parsing non-base-10 numbers, as the documentation specifies.
        * lisp.h (string_to_number): New decl, replacing ...
        (isfloat_string): Remove.
        * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
        (read1): Do not accept +. and -. as integers; this
        appears to have been a coding error.  Similarly, do not accept
        strings like +-1e0 as floating point numbers.  Do not report
        overflow for integer overflows unless the base is not 10 which
        means we have no simple and reliable way to continue.
        Break out the floating-point parsing into a new
        function string_to_number, so that Fstring_to_number parses
        floating point numbers consistently with the Lisp reader.
        (digit_to_number): Move here from data.c.  Make it static inline.
        (E_CHAR, EXP_INT): Remove, replacing with ...
        (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
        (string_to_number): New function, replacing isfloat_string.
        This function checks for valid syntax and produces the resulting
        Lisp float number too.  Rework it so that string-to-number
        no longer mishandles examples like "1.0e+".  Use strtoumax,
        so that overflow for non-base-10 numbers is reported only when
        there's no portable and simple way to convert to floating point.

        * textprop.c (set_text_properties_1): Rewrite for clarity,
        and to avoid GCC warning about integer overflow.

        * intervals.h (struct interval): Use EMACS_INT for members
        where EMACS_UINT might cause problems.  See
        <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
        (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
        * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
        All uses changed.
        (offset_intervals): Tell GCC not to worry about length overflow
        when negating a negative length.

        * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
        (overrun_check_free): Likewise.

        * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
        in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
        word size.

        * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
        (gnutls_make_error): Rename local to avoid shadowing.
        (gnutls_emacs_global_deinit): ifdef out; not used.
        (Fgnutls_boot): Use const for pointer to readonly storage.
        Comment out unused local.  Fix pointer signedness problems.

        * lread.c (openp): Don't stuff size_t into an 'int'.
        Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
        about possible signed overflow.

        * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
        (GDK_KEY_g): Don't define if already defined.
        (xg_prepare_tooltip): Avoid pointer signedness problem.
        (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.

        * process.c (Fnetwork_interface_info): Avoid left-shift undefined
        behavior with 1 << 31.  GCC 4.6.0 warns about this on 32-bit hosts.

        * xfns.c (Fx_window_property): Simplify a bit,
        to make a bit faster and to avoid GCC 4.6.0 warning.
        * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.

        * fns.c (internal_equal): Don't assume size_t fits in int.

        * alloc.c (compact_small_strings): Tighten assertion a little.

        Replace pEd with more-general pI, and fix some printf arg casts.
        * lisp.h (pI): New macro, generalizing old pEd macro to other
        conversion specifiers.  For example, use "...%"pI"d..." rather
        than "...%"pEd"...".
        (pEd): Remove.  All uses replaced with similar uses of pI.
        * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
        * alloc.c (check_pure_size): Don't overflow by converting size to int.
        * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
        * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
        * dbusbind.c (xd_append_arg): Use pI to avoid cast.
        (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
        * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
        64-bit hosts.
        (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
        * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
        * print.c (safe_debug_print, print_object): Likewise.
        (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
        to int.
        Use pI instead of if-then-else-abort.  Use %p to avoid casts,
        avoiding the 0 flag, which is not portable.
        * process.c (Fmake_network_process): Use pI to avoid cast.
        * region-cache.c (pp_cache): Likewise.
        * xdisp.c (decode_mode_spec): Likewise.
        * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
        behavior on 64-bit hosts with printf arg.
        * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
        (x_stop_queuing_selection_requests): Likewise.
        (x_get_window_property): Don't truncate byte count to an 'int'
        when tracing.

        * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
        here, since it parses constructs like leading '-' and spaces,
        which are not wanted; and it overflows with large numbers.
        Instead, simply match F[0-9]+, which is what is wanted anyway.

        * alloc.c: Remove unportable assumptions about struct layout.
        (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
        (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
        (allocate_vectorlike, make_pure_vector): Use the new macros,
        plus offsetof, to remove unportable assumptions about struct layout.
        These assumptions hold on all porting targets that I know of, but
        they are not guaranteed, they're easy to remove, and removing them
        makes further changes easier.

        * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
        This doesn't fix a bug but makes the code clearer.
        (string_overrun_cookie): Now const.  Use initializers that
        don't formally overflow signed char, to avoid warnings.
        (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
        can cause Emacs to crash when string overrun checking is enabled.
        (allocate_buffer): Don't assume sizeof (struct buffer) is a
        multiple of sizeof (EMACS_INT); it need not be, if
        alignof(EMACS_INT) < sizeof (EMACS_INT).
        (check_sblock, check_string_bytes, check_string_free_list): Protoize.

2011-04-26  Juanma Barranquero  <lekktu@gmail.com>

        * keyboard.c (QCrtl): Rename from Qrtl.  All uses changed.

        supposed to be handshaking.  (Bug#8556)
        Reported by Paul Eggert <eggert@cs.ucla.edu>.

2011-04-26  Daniel Colascione  <dan.colascione@gmail.com>

        * lisp.h (Qdebug): List symbol.

        (handle_user_signal): Break into debugger when debug-on-event
        matches the current signal symbol.

2011-04-25  Dan Nicolaescu  <dann@ics.uci.edu>

        * alloc.c (check_sblock, check_string_bytes)
        (check_string_free_list): Convert to standard C.

2011-04-25  Eli Zaretskii  <eliz@gnu.org>

        * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
        "cast to pointer from integer of different size".

        Improve doprnt and its use in verror.  (Bug#8545)
        * doprnt.c (doprnt): Document the set of format control sequences
        supported by the function.  Use SAFE_ALLOCA instead of always
        using `alloca'.

        * eval.c (verror): Don't limit the buffer size at size_max-1, that
        is one byte too soon.  Don't use xrealloc; instead xfree and
        xmalloc anew.

2011-04-24  Teodor Zlatanov  <tzz@lifelogs.com>

        * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
        callbacks stage.

        * gnutls.c: Renamed global_initialized to
        gnutls_global_initialized.  Added internals for the
        :verify-hostname-error, :verify-error, and :verify-flags
        parameters of `gnutls-boot' and documented those parameters in the
        docstring.  Start callback support.
        (emacs_gnutls_handshake): Add Woe32 support.  Retry handshake
        unless a fatal error occurred.  Call gnutls_alert_send_appropriate
        on error.  Return error code.
        (emacs_gnutls_write): Call emacs_gnutls_handle_error.
        (emacs_gnutls_read): Likewise.

        make it consistent with the commentary.  Fix typos in the
        commentary.

        * textprop.c (syms_of_textprop): Remove dead code.

        * doc.c (get_doc_string): Improve the format passed to `error'.

        * doprnt.c (doprnt): Improve commentary.

        * term.c (init_tty) [MSDOS]: Fix 1st argument to maybe_fatal.

        them with etags.

        * makefile.w32-in (globals.h): Add a dummy recipe, to make any
        changes in globals.h immediately force recompilation.
        (TAGS): Depend on $(CURDIR)/m/intel386.h and
        $(CURDIR)/s/ms-w32.h.
        (TAGS-gmake): Scan $(CURDIR)/m/intel386.h and $(CURDIR)/s/ms-w32.h.

        * character.c (Fchar_direction): Function deleted.
        (syms_of_character): Don't defsubr it.
        <char-direction-table>: Deleted.

2011-04-23  Eli Zaretskii  <eliz@gnu.org>

        Fix doprnt so it could be used again safely in `verror'.  (Bug#8435)
        * doprnt.c: Include limits.h.
        (SIZE_MAX): New macro.
        (doprnt): Return a size_t value.  2nd arg is now size_t.
        Many local variables are now size_t instead of int or unsigned.
        Improve overflow protection.  Support `l' modifier for integer
        conversions.  Support %l conversion.  Don't assume an EMACS_INT
        argument for integer conversions and for %c.

        * lisp.h (doprnt): Restore prototype.

        * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
        $(SRC)/character.h.

        * Makefile.in (base_obj): Add back doprnt.o.

        * deps.mk (doprnt.o): Add back prerequisites.

        * eval.c (internal_lisp_condition_case): Include the handler
        representation in the error message.
        (verror): Call doprnt instead of vsnprintf.  Fix an off-by-one bug
        when breaking from the loop.

        * xdisp.c (vmessage): Call doprnt instead of vsnprintf.

        * callint.c (Fcall_interactively): When displaying error message
        about invalid control letter, pass the character's codepoint, not
        a pointer to its multibyte form.  Improve display of the character
        in octal and display also its hex code.

        * character.c (char_string): Use %x to display the (unsigned)
        codepoint of an invalid character, to avoid displaying a bogus
        negative value.

        * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
        `error', not SYMBOL_NAME itself.

        * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
        character arguments to `error'.

        * charset.c (check_iso_charset_parameter): Fix incorrect argument
        to `error' in error message about FINAL_CHAR argument.  Make sure
        FINAL_CHAR is a character, and use %c when it is passed as
        argument to `error'.

        it.

        * nsfont.m: Fixed bugs in ns_get_family and
        ns_descriptor_to_entity that were caused by using free to
        deallocate memory blocks that were allocated by xmalloc (via
        xstrdup).  This caused Emacs to crash when compiled with
        XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with

        Make Emacs functions such as Fatom 'static' by default.
        This makes it easier for human readers (and static analyzers)

2011-04-12  Paul Eggert  <eggert@cs.ucla.edu>

        * sysdep.c (emacs_read, emacs_write): Check for negative sizes
        since callers should never pass a negative size.
        Change the signature to match that of plain 'read' and 'write'; see
        <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
        * lisp.h: Update prototypes of emacs_write and emacs_read.

2011-04-11  Eli Zaretskii  <eliz@gnu.org>

        * xdisp.c (redisplay_window): Don't try to determine the character
        position of the scroll margin if the window start point w->startp
        is outside the buffer's accessible region.  (Bug#8468)

2011-04-10  Eli Zaretskii  <eliz@gnu.org>

        Fix write-region and its subroutines for buffers > 2GB.
        * fileio.c (a_write, e_write): Modify declaration of arguments and
        local variables to support buffers larger than 2GB.
        (Fcopy_file): Use EMACS_INT for return value of emacs_read.

        * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
        argument, local variables, and return value.

        * lisp.h: Update prototypes of emacs_write and emacs_read.

        * sound.c (vox_write): Use ssize_t for return value of emacs_write.

2011-04-10  Paul Eggert  <eggert@cs.ucla.edu>

        * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.

        Fix more problems found by GCC 4.6.0's static checks.

        * xdisp.c (vmessage): Use a better test for character truncation.

        * charset.c (load_charset_map): <, not <=, for optimization,
        and to avoid potential problems with integer overflow.
        * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
        * casetab.c (set_identity, shuffle): Likewise.
        * editfns.c (Fformat): Likewise.
        * syntax.c (skip_chars): Likewise.

        * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
        This also lets GCC 4.6.0 generate slightly better loop code.

        * callint.c (Fcall_interactively): <, not <=, for optimization.
        (Fcall_interactively): Count the number of arguments produced,
        not the number of arguments given.  This is simpler and lets GCC
        4.6.0 generate slightly better code.

        * ftfont.c: Distingish more carefully between FcChar8 and char.
        The previous code passed unsigned char * to a functions like
        strlen and xstrcasecmp that expect char *, which does not
        conform to the C standard.
        (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
        arguments to FcPatternGetString, and explicitly cast FcChar8 * to
        char * when the C standard requires it.

        * keyboard.c (read_char): Remove unused var.

        * eval.c: Port to Windows vsnprintf (Bug#8435).
        Include <limits.h>.
        (SIZE_MAX): Define if the headers do not.
        (verror): Do not give up if vsnprintf returns a negative count.
        Instead, grow the buffer.  This ports to Windows vsnprintf, which
        does not conform to C99.  Problem reported by Eli Zaretskii.
        Also, simplify the allocation scheme, by avoiding the need for
        calling realloc, and removing the ALLOCATED variable.

        * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.

        Remove invocations of doprnt, as Emacs now uses vsnprintf.
        But keep the doprint source code for now, as we might revamp it
        and use it again (Bug#8435).
        * lisp.h (doprnt): Remove.
        * Makefile.in (base_obj): Remove doprnt.o.
        * deps.mk (doprnt.o): Remove.

        error: Print 32- and 64-bit integers portably (Bug#8435).
        Without this change, on typical 64-bit hosts error ("...%d...", N)
        was used to print both 32- and 64-bit integers N, which relied on
        undefined behavior.
        * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
        * lisp.h (error, verror): Mark as printf-like functions.
        * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
        Report overflow in size calculations when allocating printf buffer.
        Do not truncate output string at its first null byte.
        * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
        Truncate the output at a character boundary, since vsnprintf does not
        do that.
        * charset.c (check_iso_charset_parameter): Convert internal
        character to string before calling 'error', since %c now has the
        printf meaning.
        * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
        overflow when computing char to be passed to 'error'.  Do not
        pass Lisp_Object to 'error'; pass the integer instead.
        * nsfns.m (Fns_do_applescript): Use int, not long, since it's
        formatted with plain %d.

        * eval.c (internal_lisp_condition_case): Don't pass spurious arg.

        * keyboard.c (access_keymap_keyremap): Print func name, not garbage.

        * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.

        * xterm.c (x_catch_errors): Remove duplicate declaration.

        * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.

        * xdisp.c, lisp.h (message_nolog): Remove; unused.

2011-04-10  Jim Meyering  <meyering@redhat.com>

        use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
        * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
        return ssize_t not "int", and use size_t as the buffer length.
        (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
        * gnutls.h: Update declarations.
        * process.c (read_process_output): Use ssize_t, to match.
        (send_process): Likewise.

2011-04-09  Chong Yidong  <cyd@stupidchicken.com>

        * image.c (Fimagemagick_types): Doc fix, and comment cleanup.

2011-04-09  Chong Yidong  <cyd@stupidchicken.com>

        * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
        Use unsigned char, to match FcChar8 type definition.

        * xterm.c (handle_one_xevent):
        * xmenu.c (create_and_show_popup_menu):
        * xselect.c (x_decline_selection_request)
        (x_reply_selection_request): Avoid type-punned deref of X events.

2011-04-09  Eli Zaretskii  <eliz@gnu.org>

        Fix some uses of `int' instead of EMACS_INT.
        * search.c (string_match_1, fast_string_match)

        (scan_buffer, find_next_newline_no_quit)
        (find_before_next_newline, search_command, Freplace_match)
        (Fmatch_data): Make some `int' variables be EMACS_INT.

        * xdisp.c (display_count_lines): 3rd argument and return value now
        EMACS_INT.  All callers changed.

        * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.

        * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.

        * lisp.h (message, message_nolog, fatal): Mark as printf-like.

        This avoids several warnings with gcc -Wstrict-overflow.
        (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
        directly, rather than having caller test rule sign.  This avoids
        some unnecessary tests.
        * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
        (COMPOSITION_ENCODE_RULE): Arguments now must be valid.  This
        affects only one use, in DECODE_COMPOSITION_RULE, which is changed.

        * xfont.c (xfont_text_extents): Remove var that was set but not used.
        (xfont_open): Avoid unnecessary tests.

        * composite.c (composition_gstring_put_cache): Use unsigned integer.

        * composite.h, composite.c (composition_gstring_put_cache):
        Use EMACS_INT, not int, for length.

        * composite.h (COMPOSITION_DECODE_REFS): New macro,
        breaking out part of COMPOSITION_DECODE_RULE.
        (COMPOSITION_DECODE_RULE): Use it.
        * composite.c (get_composition_id): Remove unused local vars,
        by using the new macro.

        * textprop.c (set_text_properties_1): Change while to do-while,
        since the condition is always true at first.

        * intervals.c (graft_intervals_into_buffer): Mark var as used.
        (interval_deletion_adjustment): Return unsigned value.
        All uses changed.

        (Fnetwork_interface_info): Avoid possibility of int overflow.
        (read_process_output): Do adaptive read buffering even if carryover.
        (read_process_output): Simplify nbytes computation if buffered.

        * bytecode.c (exec_byte_code): Rename local to avoid shadowing.

        * print.c (print_error_message): Avoid int overflow.

        * font.c (font_list_entities): Redo for clarity,
        so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.

        * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
        (font_score): Avoid potential overflow in diff calculation.

        * fns.c (substring_both): Remove var that is set but not used.
        (sxhash): Redo loop for clarity and to avoid wraparound warning.

        * eval.c (funcall_lambda): Rename local to avoid shadowing.

        * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
        Otherwise, GCC 4.6.0 optimizes the loop check away since the check
        can always succeed if overflow has undefined behavior.

        * search.c (boyer_moore, wordify): Remove vars set but not used.
        (wordify): Omit three unnecessary tests.

        * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.

        Check for integer overflow on size calculations.

        * buffer.c (Fprevious_overlay_change): Remove var that is set
        but not used.

        * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
        Remove vars that are set but not used.
        (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
        (timer_check_2): Mark vars as initialized.

        * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.

        * image.c (lookup_image): Remove var that is set but not used.
        (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.

        * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
        that are set but not used.

        * xfns.c (make_invisible_cursor): Don't return garbage
        if XCreateBitmapFromData fails (Bug#8410).

        * xselect.c (x_get_local_selection, x_handle_property_notify):
        Remove vars that are set but not used.

        * xfns.c (x_create_tip_frame): Remove var that is set but not used.
        (make_invisible_cursor): Initialize a possibly-uninitialized variable.

        * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
        Remove var that is set but not used.
        (scroll_bar_windows_size): Now size_t, not int.
        (x_send_scroll_bar_event): Use size_t, not int, for sizes.
        Check for overflow.

        * xfaces.c (realize_named_face): Remove vars that are set but not used.
        (map_tty_color) [!defined MSDOS]: Likewise.

        (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
        All callers changed.
        (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
        (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
        (decode_coding_charset): Remove vars that are set but not used.

        * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
        that is set but not used.

        * print.c (print_object): Remove var that is set but not used.

        Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
        The gnulib version avoids calling malloc in the usual case,
        and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
        * fileio.c (Ffile_symlink_p): Use emacs_readlink.
        * filelock.c (current_lock_owner): Likewise.
        * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
        * sysdep.c: Include allocator.h, careadlinkat.h.
        (emacs_no_realloc_allocator): New static constant.
        (emacs_readlink): New function.
        * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
        ../lib/careadlinkat.h.

2011-04-04  Stefan Monnier  <monnier@iro.umontreal.ca>

        * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the

2011-04-03  Jan Djärv  <jan.h.d@swipnet.se>

        (Feval_buffer): Bind Qlexical_binding.
        (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
        Mark as dynamic.
        (syms_of_lread): Declare `lexical-binding'.

        * lisp.h (struct Lisp_Symbol): New field `declared_special'.

        * keyboard.c (eval_dyn): New fun.
        (menu_item_eval_property): Use it.

        * image.c (parse_image_spec): Use Ffunctionp.

        * fns.c (concat, mapcar1): Accept byte-code-functions.

        * eval.c (Fsetq): Handle lexical vars.
        (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
        (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
        (FletX, Flet): Obey lexical binding.
        (Fcommandp): Handle closures.
        (Feval): New `lexical' arg.
        (eval_sub): New function extracted from Feval.  Use it almost
        everywhere where Feval was used.  Look up vars in lexical env.
        Handle closures.
        (Ffunctionp): Move from subr.el.
        (Ffuncall): Handle closures.
        (apply_lambda): Remove `eval_flags'.
        (funcall_lambda): Handle closures and new byte-code-functions.
        (Fspecial_variable_p): New function.
        (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
        but without exporting it to Lisp.

        * doc.c (Fdocumentation, store_function_docstring):
        * data.c (Finteractive_form): Handle closures.

        * callint.c (Fcall_interactively): Preserve lexical-binding mode for
        interactive spec.

        * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
        New byte-codes.
        (exec_byte_code): New function extracted from Fbyte_code to handle new
        calling convention for byte-code-functions.  Add new byte-codes.

        * buffer.c (defvar_per_buffer): Set new `declared_special' field.

        * alloc.c (Fmake_symbol): Init new `declared_special' field.

2011-03-31  Juanma Barranquero  <lekktu@gmail.com>

        * xdisp.c (redisplay_internal): Fix prototype.

2011-03-31  Eli Zaretskii  <eliz@gnu.org>

        * xdisp.c (SCROLL_LIMIT): New macro.
        (try_scrolling): Use it when setting scroll_limit.
        Limit scrolling to 100 screen lines.
        (redisplay_window): Even when falling back on "recentering",
        position point in the window according to scroll-conservatively,
        scroll-margin, and scroll-*-aggressively variables.  (Bug#6671)

        (try_scrolling): When point is above the window, allow searching
        as far as scroll_max, or one screenful, to compute vertical
        distance from PT to the scroll margin position.  This prevents
        try_scrolling from unnecessarily failing when
        scroll-conservatively is set to a value slightly larger than the
        window height.  Clean up the case of PT below the margin at bottom
        of window: scroll_max can no longer be INT_MAX.  When aggressive
        scrolling is in use, don't let point enter the opposite scroll
        margin as result of the scroll.
        (syms_of_xdisp) <scroll-conservatively>: Document the
        threshold of 100 lines for never-recentering scrolling.

2011-03-31  Juanma Barranquero  <lekktu@gmail.com>

        * dispextern.h (move_it_by_lines):
        * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
        since 2000-12-29T14:24:09Z!gerd@gnu.org.  All callers changed.
        (message_log_check_duplicate): Remove parameters `prev_bol' and
        `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org.  All callers changed.
        (redisplay_internal): Remove parameter `preserve_echo_area',
        unused since 1999-07-21T21:43:52Z!gerd@gnu.org.  All callers changed.

        * indent.c (Fvertical_motion):
        * window.c (window_scroll_pixel_based, Frecenter):
        Don't pass `need_y_p' to `move_it_by_lines'.

2011-03-30  Stefan Monnier  <monnier@iro.umontreal.ca>

        * eval.c (struct backtrace): Don't cheat with negative numbers, but do
        steal a few bits to be more compact.
        (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
        Remove unneeded casts.

        * bytecode.c (Fbyte_code): CAR and CDR can GC.

2011-03-30  Zachary Kanfer  <zkanfer@gmail.com>  (tiny change)

        * keyboard.c (Fexecute_extended_command): Do log the "suggest key
        binding" message (bug#7967).

2011-03-30  Paul Eggert  <eggert@cs.ucla.edu>

        Fix more problems found by GCC 4.6.0's static checks.

        * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
        Remove unused local var.

        * editfns.c (Fmessage_box): Remove unused local var.

        * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
        (note_mode_line_or_margin_highlight, note_mouse_highlight):
        Omit unused local vars.
        * window.c (shrink_windows): Omit unused local var.
        * menu.c (digest_single_submenu): Omit unused local var.
        * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
        Omit unused local var.

        * keyboard.c (parse_modifiers_uncached, parse_modifiers):
        Don't assume string length fits in int.
        (keyremap_step, read_key_sequence): Use size_t for sizes.
        (read_key_sequence): Don't check last_real_key_start redundantly.

        * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
        instead of alloca (Bug#8344).

        * eval.c (Fbacktrace): Don't assume nargs fits in int.
        (Fbacktrace_frame): Don't assume nframes fits in int.

        * syntax.c (scan_sexps_forward): Avoid pointer wraparound.

        * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
        concerns.

        * term.c (produce_glyphless_glyph): Remove unnecessary test.

        * cm.c (calccost): Turn while-do into do-while, for clarity.

        * keyboard.c (syms_of_keyboard): Use the same style as later
        in this function when indexing through an array.  This also
        works around GCC bug 48267.

        * image.c (tiff_load): Fix off-by-one image count (Bug#8336).

        * xselect.c (x_check_property_data): Return correct size (Bug#8335).

        * chartab.c (sub_char_table_ref_and_range): Redo for slight
        efficiency gain, and to bypass a gcc -Wstrict-overflow warning.

        * keyboard.c, keyboard.h (num_input_events): Now size_t.
        This avoids undefined behavior on integer overflow, and is a bit
        more convenient anyway since it is compared to a size_t variable.

        Variadic C functions now count arguments with size_t, not int.
        This avoids an unnecessary limitation on 64-bit machines, which
        caused (substring ...) to crash on large vectors (Bug#8344).
        * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
        (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
        All variadic functions and their callers changed accordingly.
        (struct gcpro.nvars): Now size_t, not int.  All uses changed.
        * data.c (arith_driver, float_arith_driver): Likewise.
        * editfns.c (general_insert_function): Likewise.
        * eval.c (struct backtrace.nargs, interactive_p)
        (internal_condition_case_n, run_hook_with_args, apply_lambda)
        (funcall_lambda, mark_backtrace): Likewise.
        * fns.c (concat): Likewise.

2011-03-23  Paul Eggert  <eggert@cs.ucla.edu>

        Fix more problems found by GCC 4.5.2's static checks.

        * coding.c (encode_coding_raw_text): Avoid unnecessary test
        the first time through the loop, since we know p0 < p1 then.
        This also avoids a gcc -Wstrict-overflow warning.

        * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
        leading to a memory leak, possible in functions like
        load_charset_map_from_file that can allocate an unbounded number
        of objects (Bug#8318).

        * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
        that could (at least in theory) be that large.

        * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
        This is less likely to overflow, and avoids undefined behavior if
        overflow does occur.  All callers changed.  Use strtoul to scan
        for the unsigned long integer.
        (pint2hrstr): Simplify and tune code slightly.
        This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

        * scroll.c (do_scrolling): Work around GCC bug 48228.
        See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.

        * frame.c (Fmodify_frame_parameters): Simplify loop counter.
        This also avoids a warning with gcc -Wstrict-overflow.
        (validate_x_resource_name): Simplify count usage.
        This also avoids a warning with gcc -Wstrict-overflow.

        * fileio.c (Fcopy_file): Report error if fchown or fchmod
        fail (Bug#8306).

        * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).

        * process.c (Fmake_network_process): Use socklen_t, not int,
        where POSIX says socklen_t is required in portable programs.
        This fixes a porting bug on hosts like 64-bit HP-UX, where
        socklen_t is wider than int (Bug#8277).
        (Fmake_network_process, server_accept_connection):
        (wait_reading_process_output, read_process_output):
        Likewise.

        (Fmake_network_process): Define label "retry_connect" only if needed.
        (Fnetwork_interface_info): Fix pointer signedness.
        (process_send_signal): Add cast to avoid pointer signedness problem.
        (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
        (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).

        Make tparam.h and terminfo.c consistent.
        * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
        Include tparam.h instead, since it declares them.
        * cm.h (PC): Remove extern decl; tparam.h now does this.
        * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
        * terminfo.c: Include tparam.h, to check interfaces.
        (tparm): Make 1st arg a const pointer in decl.  Put it at top level.
        (tparam): Adjust signature to match interface in tparam.h;
        this removes some undefined behavior.  Check that outstring and len
        are zero, which they always are with Emacs.
        * tparam.h (PC, BC, UP): New extern decls.

        * xftfont.c (xftfont_shape): Now static, and defined only if needed.
        (xftfont_open): Rename locals to avoid shadowing.

        * xfont.c (xfont_list_family): Mark var as initialized.

        * xml.c (make_dom): Now static.

        * composite.c (composition_compute_stop_pos): Rename local to
        avoid shadowing.
        (composition_reseat_it): Remove unused locals.
        (find_automatic_composition, composition_adjust_point): Likewise.
        (composition_update_it): Mark var as initialized.
        (find_automatic_composition): Mark vars as initialized,
        with a FIXME (Bug#8290).

        * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
        (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):

        (BUF_DEC_POS): Be more systematic about renaming local temporaries
        to avoid shadowing.

        * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

        * atimer.c (start_atimer, append_atimer_lists, set_alarm):
        Rename locals to avoid shadowing.

        * sound.c (wav_play, au_play, Fplay_sound_internal):
        Fix pointer signedness.
        (alsa_choose_format): Remove unused local var.
        (wav_play): Initialize a variable to 0, to prevent undefined
        behavior (Bug#8278).

        * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.

        * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.

        * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
        clobbering (Bug#8298).
        * sysdep.c (sys_subshell): Likewise.
        Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.

        * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
        This should get cleaned up, so that child_setup has the
        same signature on all platforms.

        * callproc.c (call_process_cleanup): Now static.
        (relocate_fd): Rename locals to avoid shadowing.

2011-03-22  Chong Yidong  <cyd@stupidchicken.com>

        * xterm.c (x_clear_frame): Remove XClearWindow call.  This appears
        not to be necessary, and produces flickering.

        Define only if needed.

        * unexelf.c (unexec): Name an expression,
        to avoid gcc -Wbad-function-cast warning.
        Use a different way to cause a compilation error if anyone uses
        n rather than nn, a way that does not involve shadowing.
        (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.

        * xrdb.c (get_system_name): Likewise.
        * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
        (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
        some of which prompt warnings from gcc -Wbad-function-cast.
        (Fformat_time_string, Fencode_time, Finsert_char):
        (Ftranslate_region_internal, Fformat):

        (mark_stack): Move local variables into the #ifdef region where
        they're used.
        (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if

        Use functions, not macros, for up- and down-casing (Bug#8254).
        * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
        (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove.  All callers changed
        to use the following functions instead of these macros.
        (downcase): Adjust to lack of DOWNCASE_TABLE.  Return int, not
        EMACS_INT, since callers assume the returned value fits in int.
        (upcase1): Likewise, for UPCASE_TABLE.
        (uppercasep, lowercasep, upcase): New static inline functions.
        * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

        which gcc can warn about.
        (regex_compile, re_match_2_internal): Mark locals as initialized.
        (RETALLOC_IF): Define only if needed.
        (WORDCHAR_P): Likewise.  This one is never needed, but is used
        only in a comment talking about a compiler bug, so put inside
        the #if 0 of that comment.
        (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
        (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

        Rename locals to avoid shadowing.
        (Fvertical_motion): Mark locals as initialized.

        * casefiddle.c (casify_object, casify_region): Now static.
        (casify_region): Mark local as initialized.

        * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
        New macros, so that the caller can use some names other than
        gcpro1, gcpro2, etc.
        (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
        of the new macros.
        (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
        argument, for consistency with GCPRO2_VAR, etc: it is now the
        prefix of the variable, not the variable itself.  All uses
        changed.
        * dired.c (directory_files_internal, file_name_completion):
        Rename locals to avoid shadowing.

        Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
        An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
        dired.c's scmp function, had undefined behavior.
        * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
        (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
        * buffer.h: ... to here, because these macros use current_buffer,
        and the new implementation with inline functions needs to have
        current_buffer in scope now, rather than later when the macros
        are used.
        (downcase, upcase1): New static inline functions.
        (DOWNCASE, UPCASE1): Reimplement using these functions.
        This avoids undefined behavior in expressions like
        DOWNCASE (x) == DOWNCASE (y), which previously suffered
        from race conditions in accessing the global variables
        case_temp1 and case_temp2.
        * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
        * lisp.h (case_temp1, case_temp2): Remove their decls.
        * character.h (ASCII_CHAR_P): Move from here ...
        * lisp.h: ... to here, so that the inline functions mentioned
        above can use them.

        * fileio.c (file_name_as_directory, directory_file_name):
        (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
        Now static.
        (file_name_as_directory): Use const pointers when appropriate.
        (Fexpand_file_name): Likewise.  In particular, newdir might
        point at constant storage, so make it a const pointer.
        (Fmake_directory_internal, Fread_file_name): Remove unused vars.
        (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
        signedness issues.

        Rename locals to avoid shadowing.

        (Ftry_completion, Fall_completions): Rename or remove locals
        to avoid shadowing.

        * marker.c (bytepos_to_charpos): Remove; unused.

        * lisp.h (verify_bytepos, count_markers): New decls,
        so that gcc does not warn that these functions aren't declared.

        * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
        (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
        (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
        (copy_text): Remove unused local var.

        * filelock.c (within_one_second): Now static.
        (lock_file_1): Rename local to avoid shadowing.

        * buffer.c (fix_overlays_before): Mark locals as initialized.
        (fix_start_end_in_overlays): Likewise.  This function should be
        simplified by using pointers-to-pointers, but that's a different
        matter.
        (switch_to_buffer_1): Now static.
        (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
        (report_overlay_modification): Rename locals to avoid shadowing.

        Fix pointer signedness issue.
        (sys_subshell): Mark local as volatile if checking for lint,
        to suppress a gcc -Wclobbered warning that does not seem to be right.
        (MAXPATHLEN): Define only if needed.

        * process.c (serial_open, serial_configure): Move decls from here ...
        * systty.h: ... to here, so that they can be checked.

        * fns.c (get_random, seed_random): Move extern decls from here ...
        * lisp.h: ... to here, so that they can be checked.

        * sysdep.c (reset_io): Now static.
        (wait_for_termination_signal): Remove; unused.

        * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):
        (copy_keymap_item, append_key, push_text_char_description):
        Now static.
        (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
        (DENSE_TABLE_SIZE): Remove; unused.
        (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
        (describe_map_tree):
        Rename locals to avoid shadowing.

        * keyboard.c: Declare functions static if they are not used elsewhere.
        (echo_char, echo_dash, cmd_error, top_level_2):
        (poll_for_input, handle_async_input): Now static.
        (read_char, kbd_buffer_get_event, make_lispy_position):

        if GCC considers string literals to be constants.

        * lisp.h (fatal_error_signal): Add decl, since it's exported.

        Improve quality of tests for time stamp overflow.
        For example, without this patch (encode-time 0 0 0 1 1
        1152921504606846976) returns the obviously-bogus value (-948597
        62170) on my RHEL 5.5 x86-64 host.  With the patch, it correctly
        reports time overflow.  See
        <http://lists.gnu.org/archive/html/emacs-devel/2011-03/msg00470.html>.
        * deps.mk (editfns.o): Depend on ../lib/intprops.h.
