+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

+
+        Widely used frame validity and checking functions.

+
+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>.
+        (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
+        * font.c (Ffont_at): Likewise.
+
+2012-11-01  Jan Djärv  <jan.h.d@swipnet.se>
+
+        * widget.c (resize_cb): New function.
+        (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
+        (EmacsFrameResize): Check if all is up to date before changing frame
+        size.
+
+2012-11-02  Eli Zaretskii  <eliz@gnu.org>
+
+        Implement backtrace output for fatal errors on MS-Windows.
+        * w32fns.c (CaptureStackBackTrace_proc): New typedef.
+        (BACKTRACE_LIMIT_MAX): New macro.
+        (w32_backtrace): New function.
+        (emacs_abort): Use w32_backtrace when the user chooses not to
+        attach a debugger.  Update the text of the abort dialog.
+
+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.
+        * indent.c (Fcompute_motion, Fvertical_motion): Likewise.
+        * window.c (decode_next_window_args): Likewise.
+        (decode_any_window): Remove static.
+        * window.h (decode_any_window): Add prototype.
+        * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
+        * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
+        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.
+        * lisp.h (init_foreground_group): New decl.
+        * sysdep.c (inherited_pgroup): New static var.
+        (init_foreground_group, tcsetpgrp_without_stopping)
+        (narrow_foreground_group, widen_foreground_group): New functions.
+        (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_data): New variable
+        (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>
