+        This code should use XDisplayMotionBufferSize to check display's

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

+        field of new marker (for sanity and safety).

+
+2013-08-29  Dmitry Antipov  <dmantipov@yandex.ru>
+
+        * xterm.c (x_clear_area): Lost 7th arg because it is always False.

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

+        * lisp.h (scan_newline): Prefer ptrdiff_t to EMACS_INT.
+        * cmds.c (Fforward_line):

+        (EV_TRAILER): Call EV_TRAILER2.
+        (mouseMoved:):  Add support for mouse-autoselect-window
+        on nextstep (Bug#6888).

+
+        * regex.c (CHAR_CHARSET, CHARSET_LEADING_CODE_BASE, CHAR_HEAD_P)
+        (SINGLE_BYTE_CHAR_P, SAME_CHARSET_P, MAKE_CHAR, BYTE8_TO_CHAR):
+        Remove unused macro definitions.
+        (CHARSET_RANGE_TABLE_BITS, EXTEND_RANGE_TABLE)
+        (SET_RANGE_TABLE_WORK_AREA_BIT, SET_RANGE_TABLE_WORK_AREA):
+        Only define if emacs.
+
+2013-08-28  Dmitry Antipov  <dmantipov@yandex.ru>
+
+        Prefer enum glyph_row_area to int where appropriate.
+        * dispextern.h (enum glyph_row_area): Add ANY_AREA member.
+        Fix comment.
+        (window_box, window_box_width, window_box_left, window_box_left_offset)
+        (window_box_right, window_box_right_offset): Adjust prototypes.
+        * xdisp.c (window_box, window_box_width, window_box_left)
+        (window_box_left_offset, window_box_right, window_box_right_offset):
+        Use enum glyph_row_area.  Adjust users and tweak comment where needed.
+        (window_box_edges): Likewise.  Lost 2nd arg since it is always ANY_AREA.
+        * nsterm.m (ns_clip_to_row):
+        * w32term.c (w32_clip_to_row):
+        * xterm.c (x_clip_to_row): Likewise.
+
+2013-08-28  Dmitry Antipov  <dmantipov@yandex.ru>

+
+2013-08-28  Paul Eggert  <eggert@cs.ucla.edu>
+
+        * Makefile.in (SHELL): Now @SHELL@, not /bin/sh,
+        for portability to hosts where /bin/sh has problems.
+
+2013-08-28  Dmitry Antipov  <dmantipov@yandex.ru>

+
+2013-08-27  Paul Eggert  <eggert@cs.ucla.edu>
+
+        Simplify SELECT_TYPE-related code.
+        Like EMACS_TIME, this portability layer is no longer needed, since
+        Emacs has been using fd_set as a portability layer for some time.
+        * sysselect.h (FD_SETSIZE): Rename from MAXDESC.  All uses changed.
+        (SELECT_TYPE): Remove.  All uses changed to fd_set.

+        * atimer.h, buffer.h, dispextern.h, xgselect.h:
+        Include <time.h> rather than "systime.h"; that's all that's needed now.
+        * dispnew.c: Include <timespec.h> rather than "systime.h";
+        that's all that's needed now.
+        * systime.h (EMACS_TIME): Remove.  All uses changed to struct timespec.
+        (EMACS_TIME_RESOLUTION): Remove.  All uses changed to

+        changed to timespec_cmp.
+        * xgselect.c: Include <timespec.h>, since our .h files don't.
+
+2013-08-27  Dmitry Antipov  <dmantipov@yandex.ru>
+
+        * xterm.h (FONT_TYPE_FOR_UNIBYTE, FONT_TYPE_FOR_MULTIBYTE:)
+        * nsterm.h (FONT_TYPE_FOR_UNIBYTE, FONT_TYPE_FOR_MULTIBYTE):
+        Remove the leftovers.
+        * gtkutil.c (toplevel): Do not declare Qxft but include
+        font.h to do so.
+        * image.c (toplevel): Do not declare Vlibrary_cache because
+        it's already done in lisp.h.
+
+2013-08-27  Dmitry Antipov  <dmantipov@yandex.ru>
+
+        * lisp.h (Mouse_HLInfo): Move from here...

+        diagnostic about assigning const char * to it.
+        * xfaces.c (x_display_info) [HAVE_NS]: Remove; unused.

+
+        Fix unlikely core dump in init_tty, and simplify terminfo case.
+        * term.c (init_tty) [TERMINFO]: Fix check for buffer overrun.
+        The old version incorrectly dumped core if malloc returned a
+        buffer containing only non-NUL bytes.
+        (init_tty): Do not allocate or free termcap buffers; the
+        struct does that for us now.
+        * termchar.h (TERMCAP_BUFFER_SIZE) [!TERMINFO]: New constant.
+        (struct tty_display_info): Define members termcap_term_buffer and
+        termcap_strings_buffer only if !TERMINFO, since terminfo doesn't
+        use them.  Allocate them directly in struct rather than indirectly
+        via a pointer, to simplify init_tty.
+
+        * frame.c (check_minibuf_window): Initialize 'window' properly,
+        so that Emacs reliably aborts later if 'window' is not initialized.
+
+2013-08-26  Jan Djärv  <jan.h.d@swipnet.se>
+
+        * gtkutil.c (xg_initialize): Set gtk-menu-bar-accel to "" instead
+        of VoidSymbol (Bug#15154).
+
+2013-08-26  Dmitry Antipov  <dmantipov@yandex.ru>

+
+2013-08-26  Dmitry Antipov  <dmantipov@yandex.ru>
+
+        * window.h (struct window): Replace last_cursor with last_cursor_vpos

+2013-08-26  Dmitry Antipov  <dmantipov@yandex.ru>
+
+        Fix recovering from possible decompression error.
+        Since insert_from_gap doesn't always move point, we can't use PT as
+        the position where the partially decompressed data ends, and
+        should count how many bytes was produced so far.
+        * decompress.c (struct decompress_unwind_data): Add nbytes member.

+        * sysdep.c (set_window_size): Return negative on error,
+        nonnegative on success, rather than -1, 0, 1 on not in system,

+        (serial_configure): Remove unnecessary initialization of local.
+        (procfs_get_total_memory) [GNU_LINUX]: Don't assume system memory
+        size fits in unsigned long; this isn't true on some 32-bit hosts.
+        Avoid buffer overrun if some future version of /proc/meminfo has a
+        variable name longer than 20 bytes.
+        (system_process_attributes) [__FreeBSD__]:

+        * fileio.c (file_name_as_directory_slop): New constant.
+        (file_name_as_directory): Allow SRC to be longer than SRCLEN;
+        this can save the caller having to alloca.
+        (Ffile_name_as_directory, Fdirectory_file_name, Fexpand_file_name):
+        Use SAFE_ALLOCA, not alloca.
+        (directory_file_name, Fexpand_file_name): Leave leading "//"
+        alone, since it can be special even on POSIX platforms.
+        * callproc.c (call_process):
+        * process.c (Fformat_network_address):
+        * sysdep.c (sys_subshell):

+
+2013-08-21  Paul Eggert  <eggert@cs.ucla.edu>
+
+        * callproc.c: Fix race that killed background processes (Bug#15144).
+        (call_process): New arg TEMPFILE_INDEX.  Callers changed.
+        Record deleted process-id in critical section, not afterwards.
+        Don't mistakenly kill process created by a call-process invocation
+        that discards output and does not wait.
+
+2013-08-21  Dmitry Antipov  <dmantipov@yandex.ru>
+
+        Fix compilation with GC_MARK_STACK == GC_USE_GCPROS_AS_BEFORE

+        * alloc.c (toplevel): Remove unnecessary nested #if...#endif.
+        (mark_maybe_object) [!GC_MARK_STACK]: Define to emacs_abort
+        to shut up compiler in mark_object.
+        (dump_zombies): Convert to global and add EXTERNALLY_VISIBLE.
+
+2013-08-21  Paul Eggert  <eggert@cs.ucla.edu>
+
+        * process.c (allocate_pty) [PTY_OPEN]: Set fd's FD_CLOEXEC flag.
+        We can't portably rely on PTY_OPEN doing that, even if
+        it calls posix_openpt with O_CLOEXEC.
+
+2013-08-20  Kenichi Handa  <handa@gnu.org>

+
+        * image.c (SIGNATURE_DIGESTSIZE): Remove.
+        (struct animation_cache): Make signature a flexible array member.
+        All uses changed.  This is a tad slower but may insulate us better
+        from future changes to ImageMagick.
+
+2013-08-19  Paul Eggert  <eggert@cs.ucla.edu>
+
+        * image.c: Shrink memory needed for animation cache.

+        (struct animation_cache): Make 'signature' a fixed size array of bytes.
+        (imagemagick_create_cache): Copy the signature.  This saves
+        several KB of memory that ImageMagick wastes per signature.
+        Don't bother updating the update_time, as the caller does that now.
+        (imagemagick_prune_animation_cache): Don't destroy the signature, as
+        it's a fixed size struct member now.
+        (imagemagick_get_animation_cache): Always destroy the signature,
+        as it's now imagemagick_create_cache's responsibility to copy it.
+        Avoid duplicate calls to strcmp and to imagemagick_create_cache,
+        and use memcmp rather than strcmp.
+        eassert that ImageMagick returns a signature of the specified length.
+
+2013-08-19  Lars Magne Ingebrigtsen  <larsi@gnus.org>
+
+        * image.c (imagemagick_get_animation_cache): Don't segfault on

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

+        Fix some other minor performance problems while we're at it.
+        (imagemagick_create_cache): Clear just the members that
+        need clearing.  Don't set update_time, as caller does that now.
+        (imagemagick_prune_animation_cache, imagemagick_get_animation_cache):
+        Simplify by using pointer-to-pointer instead of a prev pointer.
+        (imagemagick_prune_animation_cache): Use make_emacs_time rather
+        than EMACS_TIME_FROM_DOUBLE, and DestroyString rather than free.
+        (imagemagick_get_animation_cache): Don't xstrdup the image signature;
+        it's already a copy.  Free the signature probe unless it's cached.
+
+        * process.c (handle_child_signal): Fix crash; deleted pid (Bug#15106).
+        This was introduced by my 2013-08-12 fix for Bug#15035.

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

+        zero is apparently not allowed.
+        (imagemagick_compute_animated_image): Allow images that say they
+        have sub-images that are bigger than the main image, but just crop

+
+2013-08-15  Eli Zaretskii  <eliz@gnu.org>
+
+        * xdisp.c (compute_window_start_on_continuation_line):
+        When WORD_WRAP is in effect, use move_it_to instead of move_it_by_lines
+        to make sure we end up setting the window start at the leftmost
+        visible character of the display line.  This avoids funky

+
+        * image.c (imagemagick_filename_hint): New arg HINT_BUFFER.

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

+        (Fdecompress_gzipped_region): Do not mishandle input buffers with
+        more than UINT_MAX bytes.  Decompress into the gap instead of into
+        an auto buffer, as this should avoid copying.  Return nil if
+        'inflate' returns Z_NEED_DICT, as we have no dictionary.  Do not
