+
+        * ralloc.c (relinquish): If a heap is ready to be relinquished,
+        but it still has blocs in it, don't return it to the system,
+        instead of aborting.  (Bug#12402)
+
+2012-10-07  Jan Djärv  <jan.h.d@swipnet.se>

+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
+        GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
+
+2012-10-06  Jan Djärv  <jan.h.d@swipnet.se>

+
+2012-10-06  Paul Eggert  <eggert@cs.ucla.edu>
+
+        * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
+
+2012-10-05  Eli Zaretskii  <eliz@gnu.org>
+
+        * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
+
+        * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
+        that time stamps of directories could also be changed.  Don't
+        request the too broad GENERIC_WRITE, only the more restrictive
+        FILE_WRITE_ATTRIBUTES access rights.
+
+        * fileio.c (Fset_file_times): Special-case ignoring errors for
+        directories only on MSDOS, not on MS-Windows.
+
+2012-10-05  Ikumi Keita  <ikumi@ikumi.que.jp>  (tiny change)
+
+        * minibuf.c (Fcompleting_read): Doc fix.  (Bug#12555)
+
+2012-10-04  Eli Zaretskii  <eliz@gnu.org>
+
+        * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
+        see whether CreateFile failed.
+
+2012-10-04  Paul Eggert  <eggert@cs.ucla.edu>
+
+        * profiler.c (handle_profiler_signal): Inhibit pending signals too,
+        to avoid similar races.
+        * keyboard.c (pending_signals): Now bool, not int.
+
+        Port timers to OpenBSD, plus check for timer failures.
+        OpenBSD problem reported by Han Boetes.
+        * 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>
+
+        * profiler.c (handle_profiler_signal): Fix a malloc race
+        that caused Emacs to hang on Fedora 17 when profiling Lisp.
+
+2012-10-02  Jan Djärv  <jan.h.d@swipnet.se>
+
+        * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
+
+2012-10-02  Eli Zaretskii  <eliz@gnu.org>
+
+        * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
+        consistent with the change in return value of 'safe_strsignal'.
+
+2012-10-02  Paul Eggert  <eggert@cs.ucla.edu>
+
+        Prefer plain 'static' to 'static inline' (Bug#12541).
+        * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
+        (bidi_set_sor_type, bidi_push_embedding_level)
+        (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)
+        (bidi_cache_reset, bidi_cache_shrink, bidi_cache_fetch_state)
+        (bidi_cache_search, bidi_cache_ensure_space)
+        (bidi_cache_iterator_state, bidi_cache_find)
+        (bidi_peek_at_next_level, bidi_set_paragraph_end)
+        (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
+        (bidi_explicit_dir_char, bidi_resolve_neutral_1):
+        Now 'static', not 'static inline'.
+
+        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.
+        (fix_start_end_in_overlays): Remove redundant recentering.
+
+2012-10-02  Juanma Barranquero  <lekktu@gmail.com>
+
+        * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
+        Update dependencies.
+
+2012-10-01  Paul Eggert  <eggert@cs.ucla.edu>
+
+        Fix a malloc race condition involving strsignal.
+        A signal can arrive in the middle of a malloc, and Emacs's signal
+        handler can invoke strsignal, which can invoke malloc, which is
+        not portable.  This race condition bug makes Emacs hang on GNU/Linux.
+        Fix it by altering the signal handler so that it does not invoke
+        strsignal.
+        * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
+        * process.c (status_message): Use const pointer, in case strsignal
+        is #defined to safe_strsignal.
+        * sysdep.c (sys_siglist, init_signals): Always define and
+        initialize a substitute sys_siglist if the system does not define
+        one, even if HAVE_STRSIGNAL.
+        (safe_strsignal): Rename from strsignal.  Always define,
+        using sys_siglist.  Return a const pointer.
+        * syssignal.h (safe_strsignal): New decl.
+        (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
+
+2012-10-01  Eli Zaretskii  <eliz@gnu.org>
+
+        * w32proc.c (timer_loop): Fix code that waits for timer
+        expiration, to avoid high CPU usage.
+
+2012-10-01  Stefan Monnier  <monnier@iro.umontreal.ca>
+
+        * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
+        (sweep_weak_table): Remove redundant prototypes.
+
+2012-10-01  Fabrice Popineau  <fabrice.popineau@gmail.com>
+
+        * emacs.c: Move the inclusion of TERM_HEADER after including
+        windows.h on WINDOWSNT.  This avoids compilation problems with
+        MSVC.
+
+2012-10-01  Eli Zaretskii  <eliz@gnu.org>
+
+        * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
+        (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
+        (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
+        as the previous version used 'void *'.
+
+        * ralloc.c (ROUNDUP): Fix last change.
+        (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
+        'size_t'.
+
+        * w32proc.c <disable_itimers>: New static flag.
+        (init_timers): Initialize it to zero, after creating the critical
+        sections used by the timer threads.
+        (term_timers): Set to 1 before deleting the critical sections.
+        (getitimer, setitimer): If disable_itimers is non-zero, return an
+        error indication without doing anything.  Reported by Fabrice
+        Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
+        (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
+        return results.
+        [!HAVE_SETITIMER]: Behave as the previous version that didn't
+        support timers.
+
+        * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
+        term_ntproc after all the other bookkeeping, to get timers working
+        as long as possible.
+
+2012-10-01  Paul Eggert  <eggert@cs.ucla.edu>
+
+        * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
+        Suggested by Juri Linkov in
+        <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
+
+        Prefer plain 'static' to 'static inline' (Bug#12541).
+        With static functions, modern compilers inline pretty well by
+        themselves; advice from programmers often hurts as much as it helps.
+        On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
+        this change shrinks the text size of the Emacs executable by 1.1%
+        without affecting CPU significantly in my benchmark.
+        * alloc.c (mem_find, live_string_p, live_cons_p, live_symbol_p)

+
+        Revert the FOLLOW-SYMLINKS change for file-attributes.
+        Doing it right would require several changes to Tramp, and there's
+        not enough time to get that tested before the freeze today.
+        * dired.c (directory_files_internal, Ffile_attributes):
+        Undo last change.
+
+        * frame.c (x_report_frame_params): Port better to wider ints.
+        Do not assume that EMACS_UINT is the same width as uprintmax_t,
+        or that pointers can be printed in 15 decimal digits.
+        Avoid GCC warnings if EMACS_UINT is wider than a pointer.

+        Prefer timer_settime if available, and prefer

+        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.
