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>

7 8
	* w32proc.c (stop_timer_thread): Fix declaration of 'err'.

9 10 11 12 13 14 15 16
	* 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.

2012-10-04  Eli Zaretskii  <eliz@gnu.org>

	* w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
	see whether CreateFile failed.

26 27 28 29 30 31
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.

32 33 34 35 36 37 38 39 40 41 42
	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

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'.

59 60 61 62 63 64 65 66 67 68 69 70
	Prefer plain 'static' to 'static inline' (Bug#12541).

	(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'.

71 72 73 74 75 76 77 78 79
	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.

80 81 82 83 84 85 86 87 88
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.
89
	(fix_start_end_in_overlays): Remove redundant recentering.

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.

120 121 122 123 124
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.

125 126 127 128 129 130
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>

133 134 135 136 137 138 139 140 141
	* 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'.

142 143 144 145 146 147 148
	* 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.
149 150 151 152
	(alarm) [HAVE_SETITIMER]: Be more conformant to the expected
	return results.
	[!HAVE_SETITIMER]: Behave as the previous version that didn't
	support timers.
153 154 155 156 157

	* 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>

160 161 162 163
	* 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>.

164 165 166 167 168 169 170 171 172 173 174 175 176 177 178 179 180 181 182 183 184 185 186 187 188 189 190 191 192 193 194 195 196 197 198 199 200 201 202 203 204 205 206 207 208 209 210 211 212 213 214 215 216 217 218 219 220 221 222 223 224 225 226 227 228 229 230 231 232 233 234 235 236 237 238 239 240 241 242 243 244 245 246 247
	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.

	(bidi_char_at_pos): Merge the two STRING_CHAR calls into one.

252 253 254 255 256 257
	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.

258 259 260 261 262
	* 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.

263 264 265 266 267 268

	Profiler improvements: more-accurate timers, overflow checks.
	* profiler.c: Don't include stdio.h, limits.h, sys/time.h,
	signal.h, setjmp.h.  Include systime.h instead.
	(saturated_add): New function.
	(record_backtrace, current_sample_interval): Use EMACS_INT, not size_t.
	(record_backtrace, handle_profiler_signal): Saturate on fixnum overflow.
	(profiler_timer, profiler_timer_ok) [HAVE_TIMER_SETTIME]:

	(profiler_cpu_running): Now of that enum type, not bool.
	All uses changed to store the new value.
	(handle_profiler_signal): Rename from sigprof_handler_1,
	for consistency with other handlers.  Do not check whether
	cpu_log is a hash-table if garbage collecting, since it
	doesn't matter in that case.
	(deliver_profiler_signal): Rename from sigprof_handler,
	for consistency with other handlers.
	(setup_cpu_timer): New function, with much of what used to be in
	Fprofiler_cpu_start.  Check for out-of-range argument.
	Prefer timer_settime if available, and prefer
	thread cputime clocks, then process cputime clocks, then
	monotonic clocks, to the old realtime clock.  Use make_timeval
	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.
	(malloc_probe): Saturate at MOST_POSITIVE_FIXNUM.
	* sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in
	non-fatal signal handlers.  Ignore SIGPROF on startup.

	in profiler.c, since sysdep.c now uses it.

	Since this stuff is now private to charset.c, there's no need for
	a public macro and no need to inline by hand.

2012-09-23  Paul Eggert  <eggert@cs.ucla.edu>

	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.

	Port better to POSIX hosts lacking _setjmp (Bug#12446).

1241
	Some instances of '#include <setjmp.h>' removed, if the

	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.

	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,

	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

	_longjmp and read afterwards.

	Assume C89 or later for math functions (Bug#12381).

	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

	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.

	no longer needed here.

	* emacs.c (abort) [!DOS_NT && !NO_ABORT]:
	Remove; sysdep.c's emacs_abort now takes its place.
	* lisp.h (emacs_abort): New decl.  All calls from Emacs code to
	'abort' changed to use 'emacs_abort'.
	* msdos.c (dos_abort) [defined abort]: Remove; not used.
	(abort) [!defined abort]: Rename to ...
	(emacs_abort): ... new name.
	* sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
	the place of the old 'abort' in emacs.c.
	* w32.c, w32fns.c (abort): Do not #undef.
	* w32.c (emacs_abort): Rename from w32_abort.

	* w32uniscribe.c (uniscribe_shape): Reverse the sign of
	offsets[j].dv, since the y axis of the screen coordinates points
	down, while the y axis of the font definition coordinates points
	up.  This fixes display of Arabic diacritics such as KASRA and
	KASRATAN.  (Bug#11860)

	Be more systematic about _setjmp vs setjmp.
	* alloc.c (test_setjmp, mark_stack):
	* image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
	(PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
	(png_load, my_error_exit, jpeg_load):
	* process.c (send_process_trap, send_process):
	Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
	The underscored versions are up to 30x faster on some hosts.
	Formerly, the code used setjmp+longjmp sometimes and
	_setjmp+_longjmp at other times, with no particular reason to
	prefer setjmp+longjmp.
