	Remove configure's --without-sync-input option (Bug#12450).
	When auditing signal-handling in preparation for cleaning it up,
	I found that SYNC_INPUT has race conditions and would be a real
	pain to fix.  Since it's an undocumented and deprecated
	configure-time option, now seems like a good time to remove it.
	Also see <http://bugs.gnu.org/11080#16>.
	* alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
	(_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
	(alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
	(malloc_hysteresis):
	(check_depth) [XMALLOC_OVERRUN_CHECK]:
	(MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):

	(bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
	(emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
	[!SYSTEM_MALLOC && !SYNC_INPUT]:
	Remove. All uses removed.
	(MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
	implementation, one that depends on whether the new macro
	XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
	is defined.
	* atimer.c (run_timers, handle_alarm_signal):
	* keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
	(handle_async_input, process_pending_signals)
	(handle_input_available_signal, init_keyboard):
	* nsterm.m (ns_read_socket):
	* process.c (wait_reading_process_output):
	* regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):

	* xterm.c (XTread_socket):
	Assume SYNC_INPUT.
	* conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
	* eval.c (handling_signal): Remove.  All uses removed.
	* lisp.h (ELSE_PENDING_SIGNALS): Remove.
	All uses replaced with the SYNC_INPUT version.
	(reset_malloc_hooks, uninterrupt_malloc, handling_signal):
	Remove decls.
	* sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
	Now static.

	to ns_term_init to avoid memory leak.

	* nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
	explicit retain/release.
	(ns_term_init): Only allow one display.  Initialize outerpool and
	ns_*_types.

	Port _setjmp fix to POSIXish hosts as well as Microsoft.
	* image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
	it's needed on POSIXish hosts that lack _setjmp.  Attempt to solve
	the Microsoft problem in a different way, by altering ../nt/config.nt.

	* w32console.c:
	* w32.c:
	* w16select.c: Remove inclusion of setjmp.h, as it is now included
	by lisp.h.  This completes removal of setjmp.h inclusion
	erroneously announced in the previous commit.  (Bug#12446)

	* lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
	more accurate.

	* image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
	not defined as a macro.  The latter happens on MS-Windows.
	(Bug#12446)

2012-09-15  Paul Eggert  <eggert@cs.ucla.edu>

	Port better to POSIX hosts lacking _setjmp (Bug#12446).
	* lisp.h: Include <setjmp.h> here, since we use its symbols here.
119
	Some instances of '#include <setjmp.h>' removed, if the
120 121 122 123 124 125 126 127 128 129 130 131 132 133 134 135 136
	only reason for the instance was because "lisp.h" was included.
	(sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
	Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
	and _longjmp with the new symbols.  Emacs already uses _setjmp if
	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.)
	* image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
	(png_load_body) [HAVE_PNG]:
	(PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
	(PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
	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.

2012-09-14  Paul Eggert  <eggert@cs.ucla.edu>

2012-09-14  Dmitry Antipov  <dmantipov@yandex.ru>

	Avoid out-of-range marker position (Bug#12426).
	* insdel.c (replace_range, replace_range_2): Adjust
	markers before overlays, as suggested by comments.
	(insert_1_both, insert_from_buffer_1, adjust_after_replace):
	Remove redundant check before calling offset_intervals.

2012-09-13  Paul Eggert  <eggert@cs.ucla.edu>

	Use a more backwards-compatible timer format (Bug#12430).
	* keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
	vector element, not from the 4th, since PSECS is now at the end.
	(Fcurrent_idle_time): Doc fix.

	Function to mark objects and remove killed buffers at once.
	* alloc.c (discard_killed_buffers): Rename to ...
	(mark_discard_killed buffers) ... new name.  Add marking
	of remaining objects.  Fix comment.  Adjust users.
	(mark_object): Do not touch frame buffer lists here.
	* frame.c (delete_frame): Reset frame buffer lists here.

	Better workaround for GNOME bug when --enable-gcc-warnings.
	* emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
	Instead, disable -Wunused-local-typedefs.  See Dmitry Antipov in
	<http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.

	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
	consistently.  Simplify mostly by not #undeffing standard symbols,
	e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
	or not as we please) rather than "defined SIGIO" (standard symbol
	that we probably shouldn't #undef).
	* conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
	Modules that need it can include it.
	[USG5_4 && emacs]: Likewise, do not include the streams stuff here.
	* dispextern.h (ignore_sigio): New decl.
	* emacs.c (shut_down_emacs): Invoke unrequest_sigio
	unconditionally, since it's now a no-op if !USABLE_SIGIO.
	* emacs.c (shut_down_emacs):
	* keyboard.c (kbd_buffer_store_event_hold):
	Use ignore_sigio rather than invoking 'signal' directly.
	* keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
	for FIONREAD.
	(FIONREAD, SIGIO): Do not #undef.
	(tty_read_avail_input): Use #error rather than a syntax error.
	* process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
	for I_PIPE, used by SETUP_SLAVE_PTY.
	(DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
	* sysdep.c (croak): Remove; no longer needed.  This bit of
	temporary code, with Fred N. Fish's comment that it's temporary,
	has been in Emacs since at least 1992!
	(init_sigio, reset_sigio, request_sigio, unrequest_sigio):
	Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
	* syssignal.h (croak): Remove decl.
	(SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
	* systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
	now that we're termios-only.
	(FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
	* term.c (dissociate_if_controlling_tty): Use #error rather than
	a run-time error.

218 219 220 221 222 223 224
	Work around GCC and GNOME bugs when --enable-gcc-warnings.
	* emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
	to work around GNOME bug 683906.
	* image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
	(struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
	This works around GCC bug 54561.

2012-09-12  Paul Eggert  <eggert@cs.ucla.edu>

	More fixes for 'volatile' and setjmp/longjmp.
	* eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
	* image.c (struct png_load_context) [HAVE_PNG]: New type.
	(png_load_body) [HAVE_PNG]:
	(jpeg_load_body) [HAVE_JPEG]:
	New function, with most of the old parent function's body.
	(png_load) [HAVE_PNG]:
	(jpeg_load) [HAVE_JPEG]:
	Invoke the new function, to avoid longjmp munging our locals.
	(struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
	(my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
	longjmp is passed 2, as the C standard doesn't guarantee this.
	Instead, store the failure code into mgr->failure_code.

269 270 271 272 273 274 275 276 277 278
	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.
	(struct catchtag): val, next, and pdlcount are now volatile.

279 280 281 282 283 284 285 286 287

	Prefer assignment to memcpy when either will do.

288 289 290 291 292
	* alloc.c (discard_killed_buffers): Tune and simplify a bit.
	Use pointer-to-a-pointer to simplify and avoid a NILP check each
	time an item is removed.  No need to mark this function 'inline';
	the compiler knows better than we do.

	Discard killed buffers from deleted window and frame objects.
	This reduces an amount of references to killed buffers and
	helps GC to reclaim them faster.
	* alloc.c (discard_killed_buffers): New function.
	(mark_object): Use it for deleted windows and frames.
	(mark_object): If symbol's value is set up for a killed buffer
	or deleted frame, restore it's global binding.
	* data.c (swap_in_global_binding): Add GC notice.
	(swap_in_symval_forwarding): Use convenient set_blv_where.

	Simplify, document, and port floating-point (Bug#12381).
	The porting part of this patch fixes bugs on non-IEEE platforms
	with frexp, ldexp, logb.
	* data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
	Now static.
	* floatfns.c: Simplify discussion of functions that Emacs doesn't
	support, by removing commented-out code and briefly listing the
	C89 functions excluded.  The commented-out stuff was confusing
	maintenance, e.g., we thought we needed cbrt but it was commented out.
	(logb): Remove decl; no longer needed.
	(isfinite): New macro, if not already supplied.
	(isnan): Don't replace any existing macro.
	(Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
	are present on all C89 platforms.
	(Ffrexp): Do not special-case zero, as frexp does the right thing
	for that case.
	(Flogb): Do not use logb, as it doesn't have the desired meaning
	on hosts that use non-base-2 floating point.  Instead, stick with
	frexp, which is C89 anyway.  Do not pass an infinity or a NaN to
	frexp, to avoid getting an unspecified result.

	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

	* lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
	SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,

	* 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.
