+ HAVE_TIMER_SETTIME is defined.
+
+ 2012-09-30 Paul Eggert <eggert@cs.ucla.edu>
+
+ Profiler improvements: more-accurate timers, overflow checks.
+ * profiler.c: Don't include stdio.h, limits.h, sys/time.h,

+ to round more-correctly when falling back to setitimer.
+ (Fprofiler_cpu_start): Use it.
+ (Fprofiler_cpu_stop): Prefer timer_settime if available.
+ Don't assume that passing NULL as the 2nd argument of setitimer
+ is the same as passing a pointer to all-zero storage.
+ Ignore SIGPROF afterwards.

+ * sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in
+ non-fatal signal handlers. Ignore SIGPROF on startup.

+ * 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.

+ Rename from their upper-case counterparts BLOCK_INPUT,
+ UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,

+ 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.

+ Remove. No need to deliver this to the parent; any thread can
+ handle this signal now. All uses replaced by underlying handler.

+ (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):

+ * 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.

+
+ * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
+ background rect may be larger (Bug#12245).
+
+ 2012-09-23 Chong Yidong <cyd@gnu.org>
+
+ * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
+

* .gdbinit: Just stop at fatal_error_backtrace.
