+        [BSD_SYSTEM && !DARWIN_OS && !__FreeBSD__]:
+        Make it a stub in this case; otherwise the build might fail,
+        and this code hasn't been tested on such hosts anyway.

+
+        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  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):
+        * macros.c (Qexecute_kbd_macro):
+        Now static.
+
+2013-02-26  Bastien Guerry  <bzg@gnu.org>
+
+        * window.c (Frecenter): Tiny docstring enhancement.
+
+2013-02-26  Paul Eggert  <eggert@cs.ucla.edu>
+
+        Minor textprop integer cleanup.
+        * intervals.h, textprop.c (add_text_properties_from_list):
+        Return void, not int, since nobody uses the return value.
+        * textprop.c (validate_plist, add_properties, remove_properties)
+        (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.
+        (Fadd_text_properties, Fremove_text_properties):
+        (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.
+        (lock_file) [WINDOWSNT]: Run the file name through
+        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>
+
+        * callint.c (Fcall_interactively): Use the right lexical environment
+        for `interactive' specs (bug#13811).
+        * eval.c (Feval): Accept a lexical environment.
+
+2013-02-25  Paul Eggert  <eggert@cs.ucla.edu>
+
+        Simplify data_start configuration (Bug#13783).
+        This is a followon simplification to the fix for Bug#13650.
+        * Makefile.in (LD_FIRSTFLAG, LIB_GCC, CRT_DIR, LIB_STANDARD)
+        (START_FILES): Remove.  All uses removed.
+        (otherobj): Remove $(VMLIMIT_OBJ), as it's now first.
+        (ALLOBJS): Move here from autodeps.mk, and with VMLIMITS_OBJ first.
+        (buildobj.h): Use it.
+        ($(ALLOBJS)): Depend on globals.h.
+        (temacs$(EXEEXT)): Use $(ALLOBJS).

+        (__do_global_dtors, __CTOR_LIST__, __DTOR_LIST__)
+        [__GNUC__ && !ORDINARY_LINK]: Remove.
+        * mem-limits.h, pre-crt0.c: Remove.
+        * unexaix.c, unexcoff.c: Don't include mem-limits.h.
+        * unexcoff.c (etext): New decl.
+        (make_hdr): Use DATA_START instead of start_of_data.
+        * vm-limit.c: Move most of mem-limits.h's contents here.
+        (data_start): New decl.  It's OK if this is approximate,

+
+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 (init_callproc):
+        * dispnew.c (init_display):
+        * sysdep.c (sys_subshell):

+
+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>

+        * 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): 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.

+
+        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

+        (SXHASH_REDUCE): Move here from fns.c, and make it inline.

+
+        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

+
+        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

+
+        * 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.

+
+        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):

+        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.

+
+        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.
