+
+        * fileio.c (Ffile_acl, Fset_file_acl): New functions.
+        (Fcopy_file): Change last arg to `preserve_extended_attributes'
+        and copy ACL entries of file in addition to SELinux context if
+        set.
+        (syms_of_fileio): Add `file-acl' and `set-file-acl'.
+
+        * Makefile.in (LIBACL_LIBS): New macro.
+        (LIBES): Use it.
+
+2012-12-15  Paul Eggert  <eggert@cs.ucla.edu>
+
+        * fileio.c (internal_delete_file): Use bool for boolean.
+
+2012-12-15  Eli Zaretskii  <eliz@gnu.org>
+
+        Fix bug #13079 on MS-Windows with temp files not being deleted.
+        * w32.h (_child_process): New members input_file and
+        pending_deletion.
+        (register_child): First argument is now pid_t.
+        (record_infile, record_pending_deletion): New prototypes.
+
+        * w32proc.c (new_child): Initialize input_file and
+        pending_deletion members of the child.
+        (delete_child): Delete the child's temporary input file, if any,
+        that is pending deletion.
+        (register_child): First argument is now pid_t.
+        (record_infile, record_pending_deletion): New functions.
+        (reap_subprocess): Fix a typo in DebPrint string.
+        (sys_spawnve, sys_kill): Use pid_t for PID arguments.
+
+        * fileio.c (internal_delete_file): Return an int again: non-zero
+        if delete-file succeeds, zero otherwise.
+
+        * lisp.h (internal_delete_file): Adjust prototype.
+
+        * callproc.c (Fcall_process): Don't overwrite infile with result
+        of DECODE_FILE.
+        [WINDOWSNT] If BUFFER is an integer, i.e. we are launching an
+        asynchronous subprocess, record the name of the input file name,
+        if any.
+        (delete_temp_file) [WINDOWSNT]: If internal_delete_file fails to
+        delete the file, record it as pending deletion when the subprocess
+        exits.
+
+2012-12-14  Eli Zaretskii  <eliz@gnu.org>
+
+        * editfns.c [HAVE_PWD_H]: Include grp.h.
+
+        * makefile.w32-in ($(BLD)/editfns.$(O)): Add $(NT_INC)/grp.h.
+
+2012-12-14  Paul Eggert  <eggert@cs.ucla.edu>
+
+        Fix permissions bugs with setgid directories etc. (Bug#13125)
+        * dired.c (Ffile_attributes): Return t as the 9th attribute,
+        to mark it as a placeholder.  The old value was often wrong.
+        The only user of this attribute has been changed to use
+        file-ownership-preserved-p instead, with its new group arg.
+        * editfns.c (Fgroup_gid, Fgroup_real_gid): New functions.
+
+2012-12-14  Stefan Monnier  <monnier@iro.umontreal.ca>
+
+        * xdisp.c (select_frame_for_redisplay, display_mode_lines):
+        Keep selected_window and selected_frame in sync.
+
+2012-12-14  Eli Zaretskii  <eliz@gnu.org>
+
+        * w32.c (stat_worker): If w32_stat_get_owner_group is zero, do not
+        try to get accurate owner and group information from NT file
+        security APIs.  This is to make most callers of 'stat' and
+        '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
+        owner and group information from 'lstat'.
+
+2012-12-13  Paul Eggert  <eggert@cs.ucla.edu>
+
+        * fileio.c (Finsert_file_contents): Don't put tail into head area,
+        as that confuses set-auto-coding, so insist on the head-read
+        returning the full 1024 bytes.  Let lseek compute the tail offset;
+        less work for us.  Do not ignore I/O errors when reading the tail.
+
+        * xdisp.c: Minor style fixes.
+        (init_iterator): Hoist assignment out of if-expression.
+        (markpos_of_region): Callers now test for sign, not for -1.
+
+2012-12-13  Dmitry Antipov  <dmantipov@yandex.ru>
+
+        Minor redisplay optimization when the region length is zero.
+        * xdisp.c (markpos_of_region): New function.
+        (init_iterator): Do not highlight the region of zero length.
+        (redisplay_window): Check whether the region is of non-zero length.
+        (try_cursor_movement): Allow if the region length is zero.
+        (try_window_reusing_current_matrix, try_window_id): Likewise.
+
+2012-12-13  Eli Zaretskii  <eliz@gnu.org>
+
+        * search.c (search_buffer): Check the inverse translations of each
+        character in pattern when the buffer being searched is unibyte.
+        (Bug#13084)
+
+2012-12-13  Paul Eggert  <eggert@cs.ucla.edu>
+
+        * fileio.c (Fvisited_file_modtime): Return (-1 ...) for nonexistent
+        files, fixing a regression from 24.2.
+        (Fverify_visited_file_modtime): Don't read uninitialized st.st_size.
+
+2012-12-13  Paul Eggert  <eggert@cs.ucla.edu>
+
+        * fileio.c (Fcopy_file): Make fstat failure as serious as open failure.
+        fstat shouldn't fail, and if it does fail copy-file should not proceed.
+        Remove unnecessary S_ISLNK test, as (contra the comments) this
+        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>

+
+2012-12-12  Daniel Colascione  <dancol@dancol.org>
+
+        * unexcw.c (fixup_executable): use posix_fallocate to ensure that
+        the dumped Emacs is not a sparse file, greatly improving Cygwin
+        "make bootstrap" performance.
+
+2012-12-11  Michael Albinus  <michael.albinus@gmx.de>
+
+        * inotify.c (inotify_callback): Generate an Emacs event for every
+        incoming inotify event.
+
+2012-12-11  Eli Zaretskii  <eliz@gnu.org>
+
+        * xdisp.c (handle_face_prop): Fix logic of computing
+        it->start_of_box_run_p.
+        (append_space_for_newline): If the glyph row is R2L, reset the
+        iterator's end_of_box_run_p flag before prepending the space glyph.
+        (extend_face_to_end_of_line): If the glyph row is R2L, reset the
+        iterator's start_of_box_run_p flag before prepending the stretch.
+        (append_glyph, produce_image_glyph, append_composite_glyph)
+        (append_stretch_glyph, append_glyphless_glyph): Reverse the
+        left_box_line_p and right_box_line_p flags of the glyph for R2L
+        glyph rows.  (Bug#13011)
+
+2012-12-11  Dmitry Antipov  <dmantipov@yandex.ru>

+        if changed buffer is not shown in a window.
+        * insdel.c (prepare_to_modify_buffer): Likewise.
+        * window.c (replace_buffer_in_windows_safely): Do nothing
+        if buffer is not shown in a window.
+        (Fforce_window_update): Likewise if string or buffer argument
+        is passed.
+
+2012-12-11  Eli Zaretskii  <eliz@gnu.org>

+        (mark_window_display_accurate_1, redisplay_window, decode_mode_spec):
+        Replace direct access to marker fields with calls
+        to marker_position and/or marker_byte_position.

+
+        * emacs.c (main): Call cache_system_info early in startup; we

+
+        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.

+
+        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.

+        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

+        * 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

+        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.

+
+        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

+        all users are long dead.  Adjust comment on mouse_position_hook.

+        Fixes point position in window under scroll-up/down-aggressively when

+        (Bug#12811)
+
+        * ralloc.c (relinquish): If real_morecore fails to return memory

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

+
+        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

+
+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

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

+
+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):

+
+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>
+

+
+        * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
+        (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use

+
+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

+        * 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

+
+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.

+
+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>

+        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.

+
+        * nsfont.m (nsfont_open, ns_glyph_metrics): Force integer advancement
+        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.

+        * 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).

+
+        * alloc.c (NSTATICS): Decrease to 0x800.
+
+2012-10-19  Stefan Monnier  <monnier@iro.umontreal.ca>

+
+2012-10-18  Jan Djärv  <jan.h.d@swipnet.se>
+

+
+        * 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.

+
+        Fix some stat-related races.
+        * fileio.c (Fwrite_region): Avoid race condition if a file is
+        removed or renamed by some other process immediately after Emacs
+        writes it but before Emacs stats it.  Do not assume that stat (or
+        fstat) succeeds.

+        rather than stat + fopen.

+        instead of calling 'stat', when what's needed is to check whether
+        a file exists.  This avoids expensive system calls on MS-Windows.
+        (Bug#12587)

+        Use unsigned for counter where wraparound-on-overflow is desired,

+        (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.

+
+2012-10-08  Daniel Colascione  <dancol@dancol.org>
+
+        * xdisp.c (start_hourglass): Call w32_note_current_window when

+        build that caused Emacs to display the hourglass cursor forever.
+
+        * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,

+
+        (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
+        Use `report_file_error' instead of `error' in order to better

+        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_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.

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

+        (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.

+
+        * 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,

+        instead of aborting.  (Bug#12402)
+
+2012-10-07  Jan Djärv  <jan.h.d@swipnet.se>
+

+
+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

+
+2012-10-06  Jan Djärv  <jan.h.d@swipnet.se>

+        (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.

+
+2012-10-05  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>
+

+
+2012-10-04  Paul Eggert  <eggert@cs.ucla.edu>
+
+        * profiler.c (handle_profiler_signal): Inhibit pending signals too,

+        * keyboard.c (pending_signals): Now bool, not int.
+
+        Port timers to OpenBSD, plus check for timer failures.
+        OpenBSD problem reported by Han Boetes.
+        * profiler.c (setup_cpu_timer): Check for failure of timer_settime
+        and/or setitimer.
+        (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
+        * syssignal.h (HAVE_ITIMERSPEC): New macro.  This is for platforms
+        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>

+
+2012-10-02  Paul Eggert  <eggert@cs.ucla.edu>
+
+        Prefer plain 'static' to 'static inline' (Bug#12541).

+
+        Count overruns when profiling; change units to ns.
+        * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
+        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.

+
+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>

+2012-10-01  Fabrice Popineau  <fabrice.popineau@gmail.com>
+
+        * emacs.c: Move the inclusion of TERM_HEADER after including

+
+        * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)

+        (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

+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%

+        * emacs.c (terminate_due_to_signal): Reset signal handler here.
+        * sysdep.c (init_signals): Do not use SA_NODEFER.  It wasn't

+
+2012-09-23  Jan Djärv  <jan.h.d@swipnet.se>
+
+        * xterm.c (x_term_init): Call fixup_locale before and after calling

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

+
+        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,

+        * lisp.h: Include <setjmp.h> here, since we use its symbols here.
+        Some instances of '#include <setjmp.h>' removed, if the

+        Unless otherwise specified, replace all uses of jmp_buf, _setjmp,

+        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.)

+        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.

+        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

+
+        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.

+
+        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

+        * 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

+
+        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.
