	* w32.c (max_filename_mbslen): New function.
	(normalize_filename, readdir): Use it to detect locales where ANSI
	encoding of file names uses a double-byte character set (DBCS).
	If a DBCS encoding is used, advance by characters using
	CharNextExA, instead of incrementing a 'char *' pointer.  Use
	_mbslwr instead of _strlwr.  (Bug#13515)

60 61 62
	* w32heap.c (allocate_heap) [!_WIN64]: Decrease the initial
	request of memory reservation to 1.7GB.  (Bug#13065)

2013-01-23  Stefan Monnier  <monnier@iro.umontreal.ca>

	* xdisp.c (message2, message2_nolog): Remove functions.
	(message3, message3_nolog): Extract nbytes and multibyteness directly
	from the string.  Change all callers.
	(message3_nolog): Don't set message_enable_multibyte since set_message
	will reset it anyway.
	(message1, message1_nolog): Use message3.
	(vmessage): Use a stack allocated buffer rather than f->message_buf.
	(with_echo_area_buffer): Remove last two arguments.  Update all callers.
	(set_message): Drop all but the second arg, which has to be a string.
	(set_message_1): Simplify now that we know that a1 is NULL and the
	second arg is a string.

2013-01-21  Dmitry Antipov  <dmantipov@yandex.ru>

2013-01-19  Paul Eggert  <eggert@cs.ucla.edu>

	* lisp.h (eabs): Define unconditionally (Bug#13419).
	The old "#if !defined (eabs)" was an unnecessary revenant of back

2013-01-19  Eli Zaretskii  <eliz@gnu.org>

	* editfns.c (get_pos_property): Use SAFE_ALLOCA_LISP, to avoid
	segfault when there are lots of overlays.

	* buffer.c (sort_overlays): Use SAFE_NALLOCA, to avoid segfault
	when there are lots of overlays.  See

205 206 207 208 209 210 211 212 213 214 215
	* fileio.c: Use O_APPEND to append.
	This corresponds better to the natural interpretation of "append",
	and avoids the need to open the output file twice, or to invoke
	lseek when APPEND is neither nil nor a number.
	This relies on POSIX 1003.1-1988 or later, which is OK nowadays.
	(Fwrite_region): Simplify.  Use O_APPEND instead of opening the
	file possibly twice, and lseeking to its end; this avoids the
	need to lseek on non-regular files.  Do not use O_EXCL and O_TRUNC
	at the same time: the combination is never needed and apparently
	it doesn't work with DOS_NT.

216 217 218
	Fix size bug on DOS_NT introduced by CIFS workaround (Bug#13149).
	* fileio.c (Fwrite_region): Use O_BINARY in checking code, too.

219 220 221 222 223 224 225
	Allow floating-point file offsets.
	Problem reported by Vitalie Spinu in
	<http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00411.html>.
	* fileio.c (emacs_lseek): Remove.
	(file_offset): New function.
	(Finsert_file_contents, Fwrite_region): Use it.

226 227 228 229 230
2013-01-19  Chong Yidong  <cyd@gnu.org>

	* emacs.c (Fkill_emacs): Set waiting_for_input to 0 to avoid
	aborting on Fsignal (Bug#13289).

	set_file_security as failure due to insufficient privileges.
	Reported by Fabrice Popineau <fabrice.popineau@supelec.fr>.

	(fstat): Return owner and group like 'stat' and 'lstat' do.

240 241 242 243 244 245 246 247 248 249 250 251 252
	Work around bug in CIFS and vboxsf file systems (Bug#13149).
	The bug was observed on Ubuntu operating inside a virtual machine,
	editing files mounted via CIFS or vboxsf from the MS Windows 7 host.
	The workaround introduces a race condition on non-buggy hosts,
	but it's an unlikely race and anyway there's a nearly identical
	nearby race that can't be fixed.
	* fileio.c (valid_timestamp_file_system, timestamp_file_system):
	New static vars.
	(Fwrite_region): Test for file system time stamp bug.
	(init_fileio): New function.
	* lisp.h (init_fileio): Declare it.
	* emacs.c (main): Call it.

253 254 255
	* fileio.c (Finsert_file_contents): Simplify new diagnostic
	and make it more consistent with other stat-failure diagnostics.

2013-01-18  Dmitry Antipov  <dmantipov@yandex.ru>

	Fix crash when inserting data from non-regular files.  See
	http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00406.html
	for the error description produced by valgrind.
	* fileio.c (read_non_regular): Rename to read_contents.
	Free Lisp_Save_Value object used to pass parameters.
	(read_non_regular_quit): Rename to read_contents_quit.
	(Finsert_file_contents): Redesign internal file reading loop to adjust
	gap and end positions after each read and so help make_gap to work
	properly.  Do not signal an I/O error too early and so do not leave
	not yet decoded characters in a buffer, which was the reason of
	redisplay crash.  Use list2 to build return value.  Adjust comments.

270 271 272 273 274 275 276 277
2013-01-17  Paul Eggert  <eggert@cs.ucla.edu>

	Close a race when statting and reading files (Bug#13149).
	* fileio.c (Finsert_file_contents): Use open+fstat, not stat+open.
	This avoids a race if the file is renamed between stat and open.
	This race is not the problem originally noted in Bug#13149;
	see <http://bugs.gnu.org/13149#73> and later messages in the thread.

278 279 280 281 282 283 284 285 286 287 288 289 290 291 292 293

	* alloc.c (format_save_value): Rename to make_save_value.
	(make_save_pointer): New function.

	Avoid unnecessary byte position calculation for the gap movement.
	Since all users of move_gap do CHAR_TO_BYTE for other purposes
	anyway, all of them should use move_gap_both instead.

	whose handle is not yet closed.  Instead, set its file descriptor
	to a negative value, so that reap_subprocess will call
745 746
	delete_child on that subprocess when its SIGCHLD arrives.
	This avoids closing handles used for communications between sys_select
747 748 749 750
	and reader_thread, which doesn't give sys_select a chance to
	notice that the process exited and invoke the SIGCHLD handler for

	Don't let call-process be a zombie factory (Bug#12980).
	Fixing this bug required some cleanup of the signal-handling code.
	As a side effect, this change also fixes a longstanding rare race
	condition whereby Emacs could mistakenly kill unrelated processes,
	and it fixes a bug where a second C-g does not kill a recalcitrant
	synchronous process in GNU/Linux and similar platforms.
	The patch should also fix the last vestiges of Bug#9488,
	a bug which has mostly been fixed on the trunk by other changes.
	* callproc.c, process.h (synch_process_alive, synch_process_death)
	(synch_process_termsig, sync_process_retcode):
	Remove.  All uses removed, to simplify analysis and so that
	less consing is done inside critical sections.
	* callproc.c (call_process_exited): Remove.  All uses replaced
	with !synch_process_pid.
	* callproc.c (synch_process_pid, synch_process_fd): New static vars.
	These take the role of what used to be in unwind-protect arg.
	All uses changed.
	(block_child_signal, unblock_child_signal):
	New functions, to avoid races that could kill innocent-victim processes.
	(call_process_kill, call_process_cleanup, Fcall_process): Use them.
	(call_process_kill): Record killed processes as deleted, so that
	zombies do not clutter up the system.  Do this inside a critical
	section, to avoid a race that would allow the clutter.
	(call_process_cleanup): Fix code so that the second C-g works again
	on common platforms such as GNU/Linux.
	(Fcall_process): Create the child process in a critical section,
	to fix a race condition.  If creating an asynchronous process,
	record it as deleted so that zombies do not clutter up the system.
	Do unwind-protect for WINDOWSNT too, as that's simpler in the
	light of these changes.  Omit unnecessary call to emacs_close
	before failure, as the unwind-protect code does that.
	* callproc.c (call_process_cleanup):
	* w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
	* process.c (record_deleted_pid): New function, containing
	code refactored out of Fdelete_process.
	(Fdelete_process): Use it.
	(process_status_retrieved): Remove.  All callers changed to use
	child_status_change.
	(record_child_status_change): Remove, folding its contents into ...
	(handle_child_signal): ... this signal handler.  Now, this
	function is purely a handler for SIGCHLD, and is not called after
	a synchronous waitpid returns; the synchronous code is moved to
	wait_for_termination.  There is no need to worry about reaping
	more than one child now.
	* sysdep.c (get_child_status, child_status_changed): New functions.
	(wait_for_termination): Now takes int * status and bool
	interruptible arguments, too.  Do not record child status change;
	that's now the caller's responsibility.  All callers changed.
	Reimplement in terms of get_child_status.
	(wait_for_termination_1, interruptible_wait_for_termination):
	Remove.  All callers changed to use wait_for_termination.
	* syswait.h: Include <stdbool.h>, for bool.
	(record_child_status_change, interruptible_wait_for_termination):
	Remove decls.
	(record_deleted_pid, child_status_changed): New decls.
