	"0" for integer "object" field.
	(dump_glyph_row): Adapt the header line to changes in dump_glyph.
	Display the newline glyph more unambiguously.

	* fileio.c (file_name_as_directory, directory_file_name): Accept
	an additional argument MULTIBYTE to indicate whether the input C
	came from a multibyte or a unibyte Lisp string; all callers
	adjusted.  Don't assume the input string is always multibyte.
	(Bug#13262)
	(Ffile_name_directory) [DOS_NT]: Handle unibyte strings correctly:
	don't ENCODE_FILE them, and return a unibyte string if the input
	was unibyte.
	(Fexpand_file_name): Don't mix unibyte with multibyte strings, and
	don't assume the input strings will always be multibyte.  If the

	* keyboard.c (record_asynch_buffer_change): Initialize an event

	it's a leftover from the deleted code.
	* frame.c (Fframep): Adjust user here ...
	* terminal.c (Fterminal_live_p): ... and here.
	* coding.c (Qmac): Now here because it's only used to denote
	end-of-line encoding type.
	(syms_of_coding): DEFSYM it.
	* frame.h (Qmac): Remove duplicated declaration.

164 165 166 167
2012-12-26  Paul Eggert  <eggert@cs.ucla.edu>

	* window.c (select_window_1): Now static, since it's used only here.

2012-12-25  Eli Zaretskii  <eliz@gnu.org>

	* window.c (window_body_cols): Subtract display margins from the

2012-12-25  Dmitry Antipov  <dmantipov@yandex.ru>

	because the outer shadowed one has the same meaning.
179 180 181 182
	* xterm.h (struct x_output): Remove toolbar_detached member since it's
	set but never used.
	* gtkutil.c (xg_tool_bar_detach_callback, xg_tool_bar_attach_callback)
	(xg_create_tool_bar): Adjust users.

2012-12-24  Dmitry Antipov  <dmantipov@yandex.ru>

	* buffer.h (BUF_COMPACT): New macro to follow the common style.
	* buffer.c (Fget_buffer_create): Use it to set compact field of
	struct buffer_text to avoid accessing an uninitialized value
	when compact_buffer is called for the first time.
	(compact_buffer): Use convenient BUF_COMPACT and BUF_MODIFF.
191 192 193
	(Fset_buffer_modified_p): Use buffer_window_count to check
	whether the buffer is displayed in some window.
	* xdisp.c (message_dolog): Likewise.

2012-12-23  Eli Zaretskii  <eliz@gnu.org>

197 198 199 200 201 202
	* w32.c (acl_set_file): If setting the file security descriptor
	fails, and the new DACL is identical to the existing one, silently
	return success.  This fixes problems for users backing up their
	own files without having the necessary privileges for setting
	security descriptors.

203 204 205 206 207 208 209 210 211 212 213 214 215 216 217 218 219
	* w32proc.c (reader_thread): Do not index fd_info[] with negative
	values.
	(reader_thread): Exit when cp->status becomes STATUS_READ_ERROR
	after WaitForSingleObject returns normally.  This expedites reader
	thread shutdown when delete_child triggers it.
	(reap_subprocess): More accurate commentary for why we call
	delete_child only when cp->fd is negative.

	* w32.c (sys_close): Do not call delete_child on a subprocess
	whose handle is not yet closed.  Instead, set its file descriptor
	to a negative value, so that reap_subprocess will call
	delete_child on that subprocess when its SIGCHLD arrives.  This
	avoids closing handles used for communications between sys_select
	and reader_thread, which doesn't give sys_select a chance to
	notice that the process exited and invoke the SIGCHLD handler for
	it.

220 221 222 223 224 225 226
2012-12-23  Jan Djärv  <jan.h.d@swipnet.se>

	* nsfns.m (Fns_do_applescript): Run event loop until script has
	been executed (Bug#12969).
	(ns_run_ascript): Chech as_script for nil, set to nil after
	executing script.

227 228 229 230
2012-12-22  Martin Rudalics  <rudalics@gmx.at>

	* window.c (Fselect_window): Reword doc-string (Bug#13248).

231 232 233 234 235
2012-12-22  Eli Zaretskii  <eliz@gnu.org>

	* w32term.c (w32fullscreen_hook): New function.
	(w32_create_terminal): Plug it into the terminal's fullscreen_hook.

236 237
2012-12-21  Eli Zaretskii  <eliz@gnu.org>

238 239
	* fileio.c (Finsert_file_contents): Doc fix.

240 241 242 243 244 245 246 247 248
	* w32proc.c (new_child, delete_child, find_child_pid): For a
	subprocess, consider its slot being in use as long as its process
	handle (procinfo.hProcess) is not NULL.  This avoids reusing the
	slot when a new process is started immediately after killing
	another one, without waiting enough time for the first process to
	be reaped and resources allocated for it be orderly freed.
	(Bug#13086)
	Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.

249 250 251 252
2012-12-21  Chong Yidong  <cyd@gnu.org>

	* buffer.c (Fset_buffer_major_mode): Doc fix (Bug#13231).

253 254
	* fns.c (Fcompare_strings): Doc fix (Bug#13081).

255
2012-12-21  Eli Zaretskii  <eliz@gnu.org>
256 257 258 259 260 261 262 263

	* w32.c (get_name_and_id): Always pass NULL as the first argument
	of lookup_account_sid.  Avoids crashes with UNC file names that
	refer to DFS domains, not to specific machine names.  (Bug#12621)
	Remove now unused argument FNAME; all callers changed.
	(get_file_owner_and_group): Remove now unused argument FNAME; all
	callers changed.

264 265 266 267 268
2012-12-21  Chong Yidong  <cyd@gnu.org>

	* editfns.c (Finsert_char): Since read-char-by-name now signals an
	error for invalid chars, don't check for a nil return value.

269 270 271 272 273 274 275 276 277 278 279
2012-12-20  Dmitry Antipov  <dmantipov@yandex.ru>

	Avoid calls to CHAR_TO_BYTE if byte position is known.
	* editfns.c (make_buffer_string_both): Use move_gap_both.
	(Fbuffer_string): Use make_buffer_string_both.
	* marker.c (buf_charpos_to_bytepos): Convert to eassert.
	Adjust comment.
	(buf_bytepos_to_charpos): Likewise.
	(charpos_to_bytepos): Remove.
	* fileio.c (Finsert_file_contents): Use move_gap_both.
	* search.c (Freplace_match): Likewise.
280
	* process.c (process_send_region): Likewise.  Use convenient
281 282 283 284 285
	names for byte positions.
	* lisp.h (charpos_to_bytepos): Remove prototype.
	* indent.c (scan_for_column): Use CHAR_TO_BYTE.
	* insdel.c (move_gap): Likewise.

286 287 288 289
2012-12-20  Paul Eggert  <eggert@cs.ucla.edu>

	* xdisp.c (redisplay_internal): Remove now-unused local.

290 291 292 293
2012-12-20  Stefan Monnier  <monnier@iro.umontreal.ca>

	* xdisp.c (select_frame_for_redisplay, ensure_selected_frame): Remove.
	(redisplay_internal): Don't bother selecting the frame to get the
294
	proper value of frame-local variables (bug#13225).
295

2012-12-20  Dmitry Antipov  <dmantipov@yandex.ru>

	* textprop.c (set_text_properties_1): Do not allow NULL interval.
	Rename 4th argument since it may be buffer or string.  Adjust comment.
	* intervals.c (graft_intervals_info_buffer): Find an interval here.

302 303 304 305 306 307
2012-12-19  Dmitry Antipov  <dmantipov@yandex.ru>

	* coding.c (Fdetect_coding_region): Do not check start and end with
	CHECK_NUMBER_COERCE_MARKER since validate_region does that itself.
	(code_convert_region): Likewise.

308 309 310 311 312 313 314 315
2012-12-18  Eli Zaretskii  <eliz@gnu.org>

	* w32.c (acl_get_file, acl_set_file): Run the file name through
	map_w32_filename, and resolve any symlinks in the file name, like
	Posix platforms do.
	(acl_set_file): Call revert_to_self, if any privileges were
	enabled.

316 317 318 319 320
2012-12-17  Juanma Barranquero  <lekktu@gmail.com>

	* makefile.w32-in ($(BLD)/editfns.$(O), $(BLD)/fileio.$(O))

2012-12-17  Paul Eggert  <eggert@cs.ucla.edu>

	Don't reraise SIGCHLD, as that can now lose (Bug#13192).
	With the 2012-12-03 fix for Bug#12980 in place, an old workaround
	for some of that bug's symptoms can now cause Emacs to abort.
	Remove the workaround.
	* process.c (wait_reading_process_output): Don't reraise SIGCHLD.
	The bug that caused SIGCHLD to get lost has been fixed, and the
	workaround for it can now cause Emacs to abort.

	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.
	(wait_for_termination): Adjust to API changes noted above.

	Assume POSIX 1003.1-1988 or later for fcntl.h (Bug#12881).
	* callproc.c (relocate_fd): Assume F_DUPFD.
	* emacs.c, term.c (O_RDWR): Remove.
	* keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
	O_NDELAY, since O_NONBLOCK is the standard name for this flag.
	* nsterm.m: Assume <fcntl.h> exists.
	* process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
	(create_pty, Fmake_network_process, server_accept_connection)
	(wait_reading_process_output, init_process_emacs):
	Assume O_NONBLOCK.
	(wait_reading_process_output): Put in a special case for WINDOWSNT
	to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
	It's not clear this is needed, but it's a more-conservative change.
	(create_process): Assume FD_CLOEXEC.
	(create_process, create_pty): Assume O_NOCTTY.
	* sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
	(reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.

	(O_NOCTTY): Remove.

	* w32proc.c (create_child): Don't clip the PID of the child
	process to fit into an Emacs integer, as this is no longer a
	restriction.
	(waitpid): Rename from sys_wait.  Emulate a Posix 'waitpid' by
	reaping only the process specified by PID argument, if that is
	positive.  Use PID instead of dead_child to know which process to
	reap.  Wait for the child to die only if WNOHANG is not in
	OPTIONS.
	(sys_select): Don't set dead_child.

	* sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
	as it is no longer needed.

	(hold_event, setPosition:portion:whole:): Send SIGIO only to self,

	(ns_select): Use emacs_write, not write, as that's more robust
	in the presence of signals.

	use the same value of thread handle.
	(start_timer_thread): If the timer thread exited (due to error),

	thread's handle here, so it gets duplicated only once, when

	* w32.c (faccessat): Rename from sys_faccessat.  (No need to use a
	different name, as the MS runtime does not have such a function,
	and probably never will.)  All callers changed.  Ignore DIRFD
	value if PATH is an absolute file name, to match Posix spec

2012-11-14  Paul Eggert  <eggert@cs.ucla.edu>

	Use faccessat, not access, when checking file permissions (Bug#12632).
	This fixes a bug that has been present in Emacs since its creation.
	It was reported by Chris Torek in 1983 even before GNU Emacs existed,
	which must set some sort of record.  (Torek's bug report was against
	a predecessor of GNU Emacs, but GNU Emacs happened to have the
	same common flaw.)  See Torek's Usenet posting
	"setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
	Posted: Fri Apr  8 14:18:56 1983.

	* conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
	* fileio.c (check_existing, check_executable, check_writable)
	(Ffile_readable_p):
	Use symbolic names instead of integers for the flags, as they're
	portable now.
	(check_writable): New arg AMODE.  All uses changed.
	Set errno on failure.
	(Ffile_readable_p): Use faccessat, not stat + open + close.
	(Ffile_writable_p): No need to call check_existing + check_writable.
	Just call check_writable and then look at errno.  This saves a syscall.
	dir should never be nil; replace an unnecessary runtime check
	with an eassert.  When checking the parent directory of a nonexistent
	file, check that the directory is searchable as well as writable, as
	we can't create files in unsearchable directories.
	(file_directory_p): New function, which uses 'stat' on most platforms
	but faccessat with D_OK (for efficiency) if WINDOWSNT.
	(Ffile_directory_p, Fset_file_times): Use it.
	(file_accessible_directory_p): New function, which uses a single
	syscall for efficiency.
	(Ffile_accessible_directory_p): Use it.
	* xrdb.c (file_p): Use file_directory_p.
	* lisp.h (file_directory_p, file_accessible_directory_p): New decls.
	* lread.c (openp): When opening a file, use fstat rather than
	stat, as that avoids a permissions race.  When not opening a file,
	use file_directory_p rather than stat.
	(dir_warning): First arg is now a usage string, not a format.
	Use errno.  All uses changed.
	* nsterm.m (ns_term_init): Remove unnecessary call to file-readable
	that merely introduced a race.
	* process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
	changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
	and similarly for the other O_* flags.
	* w32.c (sys_faccessat): Rename from sys_access and switch to
	faccessat's API.  All uses changed.
	* xrdb.c: Do not include <sys/stat.h>; no longer needed.
	(magic_db): Rename from magic_file_p.
	(magic_db, search_magic_path): Return an XrmDatabase rather than a
	char *, so that we don't have to test for file existence
	separately from opening the file for reading.  This removes a race
	fixes a permission-checking problem, and simplifies the code.
	All uses changed.
	(file_p): Remove; no longer needed.

	large values of FIELD_WIDTH argument to decode_mode_spec.

	Fix a race with verify-visited-file-modtime (Bug#12863).
	Since at least 1991 Emacs has ignored an mtime difference of no
	more than one second, but my guess is that this was to work around
	file system bugs that were fixed long ago.  Since the race is
	causing problems now, let's remove that code.
	* fileio.c (Fverify_visited_file_modtime): Do not accept a file
	whose time stamp is off by no more than a second.  Insist that the
	file time stamps match exactly.
