	to match other functions accepting character and byte positions.
	Adjust comment.
	(bidi_resolve_explicit_1, bidi_level_of_next_char): Adjust users.
	(bidi_paragraph_init): Likewise.  Use DEC_BOTH which is faster
	when you need just to move to the previous buffer position.
	* xdisp.c (Fcurrent_bidi_paragraph_direction): Use DEC_BOTH.

2013-03-07  Eli Zaretskii  <eliz@gnu.org>

2013-03-06  Paul Eggert  <eggert@cs.ucla.edu>

	Fix a build failure on OpenBSD 4.x and MirBSD (Bug#13881).
	* sysdep.c (list_system_processes)
	[BSD_SYSTEM && !DARWIN_OS && !__FreeBSD__]:
	Make it a stub in this case; otherwise the build might fail,
	and this code hasn't been tested on such hosts anyway.

2013-03-06  Dmitry Antipov  <dmantipov@yandex.ru>

	* lisp.h (find_next_newline_no_quit): Rename to find_next_newline.
	* xdisp.c (back_to_previous_line_start, forward_to_next_line_start)
	(get_visually_first_element, move_it_vertically_backward): Ajust users.
	* bidi.c (bidi_find_paragraph_start): Likewise.

2013-03-05  Paul Eggert  <eggert@cs.ucla.edu>

	FILE's lock is now always .#FILE and may be a regular file (Bug#13807).
	* filelock.c: Include <c-ctype.h>.
	(MAX_LFINFO): New top-level constant.
	(lock_info_type): Remove members pid, boot_time.  Add members at,
	dot, colon.  Change user member to be the entire buffer, not a
	pointer.  This allows us to handle the case where a foreign
	pid or boot time exceeds the local range.  All uses changed.
	(LINKS_MIGHT_NOT_WORK): New constant.
	(FREE_LOCK_INFO): Remove, as the pieces no longer need freeing.
	(defined_WINDOWSNT): Remove.
	(MAKE_LOCK_NAME, file_in_lock_file_name):
	Always use .#FILE (not .#-FILE) for the file lock,
	even if it is a regular file.
	(rename_lock_file): New function.
	(create_lock_file): Use it.
	(create_lock_file, read_lock_data):
	Prefer a symbolic link for the lock file, falling back on a
	regular file if symlinks don't work.  Do not try to create
	symlinks on MS-Windows, due to security hassles.  Stick with
	POSIXish functions (open, read, write, close, fchmod, readlink, symlink,
	link, rename, unlink, mkstemp) when creating locks, as a GNUish
	host may be using a Windowsish file system, and cannot use
	MS-Windows-only system calls.  Fall back on mktemp if mkstemp
	doesn't work.  Don't fail merely because of a symlink-contents
	length limit in the current file system; fall back on regular
	files.  Increase the symlink contents length limit to 8 KiB, this
	should be big enough for any real use and doesn't crunch the
	stack.
	(create_lock_file, lock_file_1, read_lock_data):
	Simplify allocation of lock file buffers now that they fit in 8 KiB.
	(lock_file_1): Return error number, not bool.  All callers changed.
	(ELOOP): New macro, if not already defined.
	(read_lock_data): Return size of lock file contents, not Lisp object.
	All callers changed.  Handle a race condition if some other process
	replaces a regular-file lock with a symlink lock or vice versa,
	while we're trying to read the lock.
	(current_lock_owner): Parse contents more carefully, to help avoid
	confusing a regular-file lock with some other application's use
	of the file.  Check for lock file contents being too long, or
	not parsing correctly.
	(current_lock_owner, lock_file):
	Allow foreign pid and boot times that exceed the local range.
	(current_lock_owner, lock_if_free, lock_file):
	Simplify allocation of lock file contents.
	* w32.c (sys_rename_replace): New function, containing most of
	the contents of the old sys_rename.
	(sys_rename): Use it.
	(fchmod): New dummy function.
	* w32.h (sys_rename_replace, fchmod): New decls.

2013-03-05  Eli Zaretskii  <eliz@gnu.org>

	* bidi.c (bidi_resolve_explicit_1): Don't call CHAR_TO_BYTE or
	bidi_count_bytes, as the callers now arrange for bidi_it->charpos
	to be in sync with bidi_it->bytepos.  Suggested by Dmitry Antipov
	<dmantipov@yandex.ru>.

2013-03-05  Dmitry Antipov  <dmantipov@yandex.ru>

	* composite.c (get_composition_id, fill_gstring_header):
	Use make_uninit_vector where appropriate.
	* font.c (Ffont_get_glyphs, build_style_table): Likewise.
	* xselect.c (clean_local_selection_data): Likewise.

2013-03-04  Paul Eggert  <eggert@cs.ucla.edu>

	Fix misuse of ImageMagick that caused core dump (Bug#13846).
	* image.c (imagemagick_load_image): Calculate height and width
	after flattening the image, not before.

2013-03-04  Dmitry Antipov  <dmantipov@yandex.ru>

	* font.c (Ffont_get_glyphs): Use convenient LGLYPH_NEW.
	* ftfont.c (ftfont_shape_by_flt): Likewise.
	* w32uniscribe.c (uniscribe_shape): Likewise.

2013-03-02  Paul Eggert  <eggert@cs.ucla.edu>

	The lock for FILE is now .#FILE or .#-FILE (Bug#13807).
	The old approach, which fell back on DIR/.#FILE.0 through
	DIR/.#FILE.9, had race conditions that could not be easily fixed.
	If DIR/.#FILE is a non-symlink file, Emacs now does not create a
	lock file for DIR/FILE; that is, DIR/FILE is no longer partly
	protected by a lock if DIR/.#FILE is a non-symlink file ("partly"
	because the locking mechanism was never reliable in that case).
	This patch fixes this and other bugs discovered by a code
	inspection that was prompted by
335
	<https://lists.gnu.org/r/emacs-devel/2013-02/msg00531.html>.
336 337 338 339 340 341 342 343 344 345 346 347 348 349 350 351 352 353 354 355 356 357 358 359 360 361 362 363 364 365 366 367 368 369 370 371 372 373 374 375 376 377 378 379 380 381 382 383 384 385 386 387 388 389 390 391 392 393 394 395 396 397 398 399 400 401 402 403 404 405 406 407 408 409 410 411 412 413 414 415 416 417 418 419 420 421 422 423 424 425 426 427 428 429 430 431 432 433 434 435 436 437 438 439 440 441 442 443 444 445 446 447 448 449 450 451 452 453 454 455 456 457 458 459 460 461 462 463 464 465 466 467 468 469 470 471 472 473 474 475 476 477 478 479 480 481 482 483 484 485 486 487 488 489 490 491 492 493 494 495 496
	Also, this patch switches to .#-FILE (not .#FILE) on MS-Windows,
	to avoid interoperability problems between the MS-Windows and
	non-MS-Windows implementations.  MS-Windows and non-MS-Windows
	instances of Emacs now ignore each others' locks.
	* filelock.c (defined_WINDOWSNT): New constant.
	(MAKE_LOCK_NAME, fill_in_lock_file_name):
	Don't create DIR/.#FILE.0 through DIR/.#FILE.9.  Instead, create
	DIR/.#FILE symlinks on non-MS-Windows hosts, and DIR/.#-FILE
	regular files on MS-Windows hosts.
	(MAKE_LOCK_NAME, unlock_file, Ffile_locked_p):
	Use SAFE_ALLOCA to avoid problems with long file names.
	(MAX_LFINFO): Now a local constant, not a global macro.
	(IS_LOCK_FILE): Remove.
	(lock_file_1): Don't inspect errno if symlink call succeeds;
	that's not portable.
	(lock_file): Document that this function can return if lock
	creation fails.
	(lock_file): Don't access freed storage.

2013-03-02  Andreas Schwab  <schwab@linux-m68k.org>

	* lisp.h (XPNTR) [!USE_LSB_TAG]: Remove extra paren.  (Bug#13734)

2013-03-02  Paul Eggert  <eggert@cs.ucla.edu>

	* textprop.c: Use bool for booleans.
	(validate_interval_range, Fadd_text_properties)
	(Fremove_text_properties): Prefer bool to int when either works.

2013-03-02  Eli Zaretskii  <eliz@gnu.org>

	* textprop.c (Fadd_text_properties, Fremove_text_properties):
	If the interval tree changes as a side effect of calling
	modify_region, re-do processing starting from the call to
	validate_interval_range.  (Bug#13743)

2013-02-28  Eli Zaretskii  <eliz@gnu.org>

	* w32.c (sys_open): Don't reset the flags for FD in fd_info[].
	(Bug#13546).

2013-02-27  Eli Zaretskii  <eliz@gnu.org>

	* filelock.c (create_lock_file) [WINDOWSNT]: Use _sopen with
	_SH_DENYRW flag, instead of emacs_open, to deny any other process
	access to the lock file until it is written and closed.
	(Bug#13807)

2013-02-26  Bastien Guerry  <bzg@gnu.org>

	* window.c (Frecenter): Tiny docstring enhancement.

2013-02-26  Paul Eggert  <eggert@cs.ucla.edu>

	Minor textprop integer cleanup.
	* intervals.h, textprop.c (add_text_properties_from_list):
	Return void, not int, since nobody uses the return value.
	* textprop.c (validate_plist, add_properties, remove_properties)
	(Fadd_text_properties):
	Don't assume list length fits in int.
	(interval_has_all_properties, interval_has_some_properties)
	(interval_has_some_properties_list, add_properties, remove_properties)

2013-02-25  Eli Zaretskii  <eliz@gnu.org>

	Implement CLASH_DETECTION for MS-Windows.

	* filelock.c [WINDOWSNT]: Include w32.h.
	(MAKE_LOCK_NAME): Don't use 'lock', it clashes with MS runtime
	function of that name.  Up-case the macro arguments.
	(IS_LOCK_FILE): New macro.
	(fill_in_lock_file_name): Use IS_LOCK_FILE instead of S_ISLNK.
	(create_lock_file): New function, with body extracted from
	lock_file_1.
	[WINDOWSNT]: Implement lock files by writing a regular file with
	the lock information as its contents.
	(read_lock_data): New function, on Posix platforms just calls
	emacs_readlinkat.
	[WINDOWSNT]: Read the lock info from the file.
	(current_lock_owner): Call read_lock_data instead of calling
	emacs_readlinkat directly.
	(lock_file) [WINDOWSNT]: Run the file name through
	dostounix_filename.

	* w32proc.c (sys_kill): Support the case of SIG = 0, in which case
	just check if the process by that PID exists.

	* w32.c (sys_open): Don't reset the _O_CREAT flag if _O_EXCL is
	also present, as doing so will fail to error out if the file
	already exists.

	* makefile.w32-in ($(BLD)/filelock.$(O)): Depend on src/w32.h.

	* textprop.c (Fadd_text_properties, Fremove_text_properties)
	(Fremove_list_of_text_properties): Skip all of the intervals in
	the region between START and END that already have resp. don't
	have the requested properties, not just the first one.
	Add assertions that the loop afterwards always modifies the
	properties.  (Bug#13743)

	($(ALLOBJS)): Depend on globals.h.
	(temacs$(EXEEXT)): Use $(ALLOBJS).

	* deps.mk (vm-limit.o):
	* makefile.w32-in ($(BLD)/vm-limit.$(O)):

	* emacs.c (__do_global_ctors, __do_global_ctors_aux)
	(__do_global_dtors, __CTOR_LIST__, __DTOR_LIST__)
	[__GNUC__ && !ORDINARY_LINK]: Remove.
	* mem-limits.h, pre-crt0.c: Remove.
	* unexaix.c, unexcoff.c: Don't include mem-limits.h.

	(make_hdr): Use DATA_START instead of start_of_data.
	* vm-limit.c: Move most of mem-limits.h's contents here.

	so simplify-away some unnecessary exactness.
	(POINTER): Remove; all uses removed.
	(data_space_start): Now char *, to avoid casts.
	(exceeds_lisp_ptr): New function, replacing the old
	EXCEEDS_LISP_PTR macro.  All uses changed.

	(start_of_data) [!CANNOT_DUMP || !SYSTEM_MALLOC]: Remove.
	(memory_warnings): Use data_start instead of start_of_data.

	Assume C89 or better.
	* ralloc.c (SIZE, POINTER, NIL):
	* vm-limit.c (POINTER):

2013-02-22  Claudio Bley  <claudio.bley@gmail.com>

	* w32.c (emacs_gnutls_pull): Don't call 'select', and don't loop.

2013-02-15  Paul Eggert  <eggert@cs.ucla.edu>

	Fix AIX port (Bug#13650).
	* lisp.h (XPNTR) [!USE_LSB_TAG && DATA_SEG_BITS]:
	Fix bug introduced in 2012-07-27 change.  DATA_SEG_BITS, if set,
	was #undeffed earlier, so it cannot be used as a macro here.
	Use the constant and not the macro.

2013-02-15  Eli Zaretskii  <eliz@gnu.org>

	* w32proc.c (new_child): If no vacant slots are found in
	child_procs[], make another pass looking for slots whose process

	* keyboard.c (syms_of_keyboard): Further tweaks of docstring.

2013-02-13  Dmitry Antipov  <dmantipov@yandex.ru>

2013-02-13  Paul Eggert  <eggert@cs.ucla.edu>

	Improve AIX port some more (Bug#13650).
	With this, it should be as good as it was in 23.3, though it's
	still pretty bad: the dumped emacs does not run.  See Mark Fleishman in

	* unexaix.c (start_of_text): Remove.
	(_data, _text): Declare as char[], not int, as AIX manual suggests.
	(bias, lnnoptr, text_scnptr, data_scnptr, load_scnptr)
	(orig_load_scnptr, orig_data_scnptr):
	Now off_t, not long, since they are file offsets.
	(make_hdr): Use _data, not start_of_data ().
	This is the key part of the fix.
	(make_hdr, unrelocate_symbols): Use off_t for file offsets.
	(unrelocate_symbols): Cast pointers to intptr_t, not to ulong.

	* pre-crt0.c (data_start): Initialize to 1.
	This ports to compilers that optimize the external declaration
	'int x = 0;' as if it were 'int x;' to shrink the executable.

	Improve AIX port (Bug#13650).
	This doesn't fix the bug, but it makes progress: Emacs builds now.
	* unexaix.c: Include inttypes.h, stdarg.h.
	(report_error, report_error_1): Mark as _Noreturn.
	(report_error): Don't report the wrong errno.
	(report_error_1): Now varargs.  All callers changed.
	(make_hdr): Use uintptr_t, not unsigned, when converting pointers
	to unsigned.  Don't use ADDR_CORRECT, as it no longer exists.
	(write_ptr): Use %p to print address rather than %lx and a cast
	to unsigned long.  Grow buffer a bit, to be safer.

2013-02-13  Eli Zaretskii  <eliz@gnu.org>

	* bidi.c (bidi_resolve_neutral): After finding the next
	non-neutral character, accept NEUTRAL_ON type as well, because
	directional control characters, such as LRE and RLE, have their
	type converted to that by bidi_resolve_weak.  This avoids aborts
	when LRE/RLE follows a run of neutrals.
	(bidi_move_to_visually_next): Assert that return value of
	bidi_peek_at_next_level is non-negative.  Negative values will
	cause an infloop.

2013-02-13  Paul Eggert  <eggert@cs.ucla.edu>

	Minor getenv-related fixes.
	* callproc.c (Fcall_process_region) [!DOS_NT]:
	Avoid unnecessary duplicate call to getenv.
	* callproc.c (init_callproc):
	* dispnew.c (init_display):
	* sysdep.c (sys_subshell):
	Omit unnecessary cast of getenv or egetenv.

2013-02-13  Juanma Barranquero  <lekktu@gmail.com>

	* makefile.w32-in ($(BLD)/filelock.$(O), $(BLD)/sysdep.$(O)):
	Update dependencies.

2013-02-12  Eli Zaretskii  <eliz@gnu.org>

	* xdisp.c (redisplay_internal): Don't set w->region_showing to the
	marker's position.
	(display_line): Set w->region_showing to the value of
	it->region_beg_charpos, not to -1.  This fixes redisplay
	optimization when cursor is moved up after M->.  (Bug#13623)
	(Bug#13626)
	(try_scrolling): Scroll text up more if point is too close to ZV
	and inside the scroll margin.  This makes sure point is moved

	* xdisp.c (move_it_vertically_backward, move_it_by_lines):
	When text lines are longer than window's screen lines, don't move back
	too far.  This speeds up some redisplay operations.  (Bug#13675)

2013-02-10  Dmitry Antipov  <dmantipov@yandex.ru>

	* syntax.c (scan_sexps_forward): Fix byte position calculation
	Bug#13664 (a.k.a Bug#13667) introduced with 2013-02-08 change.

2013-02-10  Paul Eggert  <eggert@cs.ucla.edu>

	* fileio.c (Fexpand_file_name): Omit confusing pointer comparison
	that was not needed.

2013-02-09  Paul Eggert  <eggert@cs.ucla.edu>

	Minor hashing refactoring.
	* fns.c (SXHASH_REDUCE): Move to lisp.h.
	(sxhash_float): Return EMACS_UINT, for consistency with the other
	hash functions.
	* lisp.h (INTMASK): Now a macro, since SXHASH_REDUCE is now a
	non-static inline function and therefore can't use static vars.
	(SXHASH_REDUCE): Move here from fns.c, and make it inline.
	* profiler.c (hashfn_profiler): Use SXHASH_REDUCE, to be consistent
	with the other hash functions.

2013-02-04  Paul Eggert  <eggert@cs.ucla.edu>

	* fileio.c (Qchoose_write_coding_system): Now static.

2013-02-04  Eli Zaretskii  <eliz@gnu.org>

	* xdisp.c (window_buffer_changed): region_showing can be negative,
	which still means region is being displayed.
	(redisplay_internal): Resurrect code that forced redisplay of the
	whole window when showing region and the mark has changed.
	Record the new mark position to allow redisplay optimizations.
	(display_line): If it->region_beg_charpos is non-zero, set the
	window's region_showing member to -1.  (Bug#13623)  (Bug#13626)

	* window.h (struct window) <region_showing>: Declare ptrdiff_t,
	not bitfield of 1 bit.

2013-02-03  Daniel Colascione  <dancol@dancol.org>

	* emacs.c: Use execvp, not execv, when DAEMON_MUST_EXEC, so that
	daemon mode works on cygw32 when Emacs is installed and not just
	during development.

2013-02-02  Paul Eggert  <eggert@cs.ucla.edu>

	Avoid file time stamp bug on MS-Windows (Bug#13149).
	* fileio.c (Fwrite_region): Don't use the heuristic on empty files,
	as FAT32 doesn't update time stamps when truncating them.
	Also, check that a file time stamp is not a multiple of 100 ns;
	this should catch all instances of the problem on MS-Windows,
	as its native file system resolution is 100 ns or worse, and
	checking for a non-multiple of 100 ns should impose only a small
	overhead on systems with ns resolution.

2013-02-02  Eli Zaretskii  <eliz@gnu.org>

	Avoid encoding file names on MS-Windows when they need to be run
	through dostounix_filename.
	* w32.c (normalize_filename): Accept an additional argument
	MULTIBYTE; if non-zero, traverse the file name by bytes and don't
	downcase it even if w32-downcase-file-names is non-nil.
	(dostounix_filename): Accept an additional argument MULTIBYTE and
	pass it to normalize_filename.
	(emacs_root_dir): Adjust.

	* msdos.h (dostounix_filename): Adjust prototype.

	* w32.h (dostounix_filename): Adjust prototype.

	* msdos.c (dostounix_filename): Accept an additional argument and
	ignore it.
	(init_environment): Adjust callers of dostounix_filename.

	* fileio.c (Ffile_name_directory, file_name_as_directory)
	(directory_file_name, Fexpand_file_name)
	(Fsubstitute_in_file_name): [DOS_NT] Adjust call to
	dostounix_filename.
	[WINDOWSNT]: Downcase file names if w32-downcase-file-names is
	non-nil.
	(Fsubstitute_in_file_name): [DOS_NT] Don't downcase environment
	variables, as egetenv is case-insensitive for DOS_NT.

	* dired.c (file_name_completion): Don't call Fdirectory_file_name
	with an encoded file name.

	* w32proc.c (Fw32_short_file_name, Fw32_long_file_name):
	Adjust calls to dostounix_filename.

	* w32fns.c (Fx_file_dialog): Adjust call to dostounix_filename.

	dostounix_filename.

	* callproc.c (Fcall_process) [MSDOS]: Adjust call to
	dostounix_filename.

	* callproc.c (Fcall_process): Make sure program name in PATH and
	new_argv[0] is encoded, if needed.  Otherwise, un-encoded string
	is passed to exec/spawnve, which fails unless the file-name
	encoding is UTF-8.

	* w32proc.c (sys_spawnve): Make sure escape_char is initialized,
	even if w32-quote-process-args is nil.

2013-02-01  Paul Eggert  <eggert@cs.ucla.edu>

	Fix timestamp bug when write-region appends nothing (Bug#13149).
	* fileio.c (Fwrite_region): When neither O_EXCL nor O_TRUNC is used,
	the file's time stamp doesn't change if Emacs happens to write nothing
	to the file, and on a buggy file system this could cause Emacs to
	incorrectly infer that the file system doesn't have the bug.
	Avoid this problem by inhibiting the inference in this case.

2013-02-01  Dmitry Antipov  <dmantipov@yandex.ru>

	* window.h (struct window): Convert base_line_number, base_line_pos
	and column_number_displayed members from Lisp_Object to ptrdiff_t.
	Convert region_showing member from Lisp_Object to bitfield.
	Remove sequence_number member.  Adjust comments.

	(display_mode_lines, decode_mode_spec): Adjust users.
	* .gdbinit (pwinx): Do not print sequence_number.

2013-02-01  Paul Eggert  <eggert@cs.ucla.edu>

	Use fdopendir, fstatat and readlinkat, for efficiency (Bug#13539).
	* conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): Remove.
	* dired.c: Include <fcntl.h>.
	(open_directory): New function, which uses open and fdopendir
	rather than opendir.  DOS_NT platforms still use opendir, though.
	(directory_files_internal, file_name_completion): Use it.
	(file_attributes): New function, with most of the old Ffile_attributes.
	(directory_files_internal, Ffile_attributes): Use it.

	* fileio.c: Include <allocator.h>, <careadlinkat.h>.
	(emacs_readlinkat): New function, with much of the old
	Ffile_symlink_p, but with an fd argument for speed.
	It uses readlinkat rather than careadlinkatcwd, so that it
	need not assume the working directory.
	(Ffile_symlink_p): Use it.
	* filelock.c (current_lock_owner): Use emacs_readlinkat
	rather than emacs_readlink.
	* lisp.h (emacs_readlinkat): New decl.
	(READLINK_BUFSIZE, emacs_readlink): Remove.
	* sysdep.c: Do not include <allocator.h>, <careadlinkat.h>.
	(emacs_norealloc_allocator, emacs_readlink): Remove.
	This stuff is moved to fileio.c.
	* w32.c (fstatat, readlinkat): New functions.
	(careadlinkat): Don't check that fd == AT_FDCWD.
	(careadlinkatcwd): Remove; no longer needed.

	* w32.c (parse_root, get_volume_info, readdir, read_unc_volume)
	(logon_network_drive, stat_worker, symlink, chase_symlinks):
	Use CharNextExA and CharPrevExA to iterate over file names encoded in
	DBCS.  (Bug#13553)

	* w32.c (w32_get_long_filename, init_environment, readlink):
	Support file names encoded in DBCS codepages.
	(readlink): Use the current file-name-coding-system, not the ANSI
	codepage, to decode and handle targets of symlinks.

2013-01-28  Eli Zaretskii  <eliz@gnu.org>

	* w32.c (opendir): Now accepts a 'const char *'.

2013-01-28  Dmitry Antipov  <dmantipov@yandex.ru>

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

	* xdisp.c (message2, message2_nolog): Remove functions.
	(message3, message3_nolog): Extract nbytes and multibyteness directly

	slots is non-nil.  Call mark_window_display_accurate_1 for
	the leaf windows only.
	(mark_window_display_accurate_1): Always assume leaf window.
	Adjust comment.

2013-01-22  Paul Eggert  <eggert@cs.ucla.edu>

	* emacs.c (Qkill_emacs_hook): Now static.

	* fileio.c (Finsert_file_contents): Simplify.
	Remove unnecessary assignments and tests.

2013-01-21  Eli Zaretskii  <eliz@gnu.org>

	* w32.c (acl_set_file): Don't test for errors unless
	set_file_security returns FALSE.  Avoids spurious errors when
	saving files.

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

	* fileio.c (Finsert_file_contents): Revert code introduced at
	2013-01-18 in favor of the simpler and generally better fix.
	Save stack space by removing 'buffer' and reusing 'read_buf'
	where appropriate.

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
	when this macro was called "abs".  Document 'eabs' better.

2013-01-19  Glenn Morris  <rgm@gnu.org>

	* fns.c (Frandom): Doc fix.

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

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

	* 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.

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

	Allow floating-point file offsets.
	Problem reported by Vitalie Spinu in
1279

	* fileio.c (emacs_lseek): Remove.
	(file_offset): New function.
	(Finsert_file_contents, Fwrite_region): Use it.

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).

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

	* w32.c (acl_set_file): Treat ERROR_ACCESS_DENIED from
	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.

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

	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.

	* 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.

	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.

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;

	(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
	input strings are multibyte, decode strings obtained from C
	library functions.

2012-12-26  Dmitry Antipov  <dmantipov@yandex.ru>

	* lisp.h (toplevel): Add two notices to the comment about

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

	* xdisp.c (redisplay_window): Remove inner local variable
	because the outer shadowed one has the same meaning.
	* 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.
	(Fset_buffer_modified_p): Use buffer_window_count to check

	* xdisp.c (message_dolog): Likewise.

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

	* 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.

	* 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.

2012-12-23  Jan Djärv  <jan.h.d@swipnet.se>

	* nsfns.m (Fns_do_applescript): Run event loop until script has

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

	* fileio.c (Finsert_file_contents): Doc fix.

	* 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>.

2012-12-21  Chong Yidong  <cyd@gnu.org>

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

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

	* 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.

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.

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.

	Adjust comment.
	(buf_bytepos_to_charpos): Likewise.

	proper value of frame-local variables (bug#13225).

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.

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.

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.

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.

2012-12-16  Paul Eggert  <eggert@cs.ucla.edu>

	* Makefile.in (LIBACL_LIBS): New macro.
	(LIBES): Use it.

2012-12-15  Paul Eggert  <eggert@cs.ucla.edu>

	* fileio.c (internal_delete_file): Use bool for boolean.

2012-12-15  Eli Zaretskii  <eliz@gnu.org>

	Fix bug #13079 on MS-Windows with temp files not being deleted.
	* w32.h (_child_process): New members input_file and
	pending_deletion.
	(register_child): First argument is now pid_t.
	(record_infile, record_pending_deletion): New prototypes.

	* w32proc.c (new_child): Initialize input_file and
	pending_deletion members of the child.
	(delete_child): Delete the child's temporary input file, if any,
	that is pending deletion.
	(register_child): First argument is now pid_t.
	(record_infile, record_pending_deletion): New functions.
	(reap_subprocess): Fix a typo in DebPrint string.
	(sys_spawnve, sys_kill): Use pid_t for PID arguments.

	* fileio.c (internal_delete_file): Return an int again: non-zero
	if delete-file succeeds, zero otherwise.

	* lisp.h (internal_delete_file): Adjust prototype.

	* callproc.c (Fcall_process): Don't overwrite infile with result
	of DECODE_FILE.
	[WINDOWSNT] If BUFFER is an integer, i.e. we are launching an
	asynchronous subprocess, record the name of the input file name,
	if any.
	(delete_temp_file) [WINDOWSNT]: If internal_delete_file fails to
	delete the file, record it as pending deletion when the subprocess
	exits.

2012-12-14  Eli Zaretskii  <eliz@gnu.org>

	* editfns.c [HAVE_PWD_H]: Include grp.h.

	The only user of this attribute has been changed to use
	file-ownership-preserved-p instead, with its new group arg.
	* editfns.c (Fgroup_gid, Fgroup_real_gid): New functions.

	* w32.c (stat_worker): If w32_stat_get_owner_group is zero, do not
	try to get accurate owner and group information from NT file
	security APIs.  This is to make most callers of 'stat' and
	'lstat', which don't need that information, much faster.

	* dired.c (Ffile_attributes) [WINDOWSNT]:
	Set w32_stat_get_owner_group to a non-zero value, to request accurate
	owner and group information from 'lstat'.

2012-12-13  Paul Eggert  <eggert@cs.ucla.edu>

	* fileio.c (Finsert_file_contents): Don't put tail into head area,
	as that confuses set-auto-coding, so insist on the head-read
	returning the full 1024 bytes.  Let lseek compute the tail offset;
	less work for us.  Do not ignore I/O errors when reading the tail.

	* fileio.c (Fvisited_file_modtime): Return (-1 ...) for nonexistent
	files, fixing a regression from 24.2.
	(Fverify_visited_file_modtime): Don't read uninitialized st.st_size.

2012-12-13  Paul Eggert  <eggert@cs.ucla.edu>

	* fileio.c (Fcopy_file): Make fstat failure as serious as open failure.
	fstat shouldn't fail, and if it does fail copy-file should not proceed.
	Remove unnecessary S_ISLNK test, as (contra the comments) this
	function can't copy symlinks.  Improve quality of error message
	when attempting to copy files that are neither regular files nor
	directories.

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

2012-12-12  Daniel Colascione  <dancol@dancol.org>

	* unexcw.c (fixup_executable): Use posix_fallocate to ensure that
	the dumped Emacs is not a sparse file, greatly improving Cygwin
	"make bootstrap" performance.

2012-12-11  Michael Albinus  <michael.albinus@gmx.de>

	* inotify.c (inotify_callback): Generate an Emacs event for every
	incoming inotify event.

2012-12-11  Eli Zaretskii  <eliz@gnu.org>

	* xdisp.c (handle_face_prop): Fix logic of computing
	it->start_of_box_run_p.
	(append_space_for_newline): If the glyph row is R2L, reset the
	iterator's end_of_box_run_p flag before prepending the space glyph.
	(extend_face_to_end_of_line): If the glyph row is R2L, reset the
	iterator's start_of_box_run_p flag before prepending the stretch.
	(append_glyph, produce_image_glyph, append_composite_glyph)
	(append_stretch_glyph, append_glyphless_glyph): Reverse the
	left_box_line_p and right_box_line_p flags of the glyph for R2L
	glyph rows.  (Bug#13011)

	(hinst): Remove unneeded extern declaration.
	(_start): Remove initialization of above variables; remove
	initialization of hinst, as cache_system_info now does that.

2012-12-07  Paul Eggert  <eggert@cs.ucla.edu>

	* sysdep.c (get_child_status): Abort on internal error (Bug#13086).
	This will cause a production Emacs to dump core instead of
	infinite-looping.

2012-12-07  Dmitry Antipov  <dmantipov@yandex.ru>

	* frame.c (make_frame): Do not set window's buffer to t.
	* window.c (Fsplit_window_internal): Likewise.  Previously it was
	used to indicate that the window is being set up.  Now we use
	set_window_buffer for all new windows, so the condition in ...
	(Fset_window_buffer): ... is always true and can be removed.

2012-12-07  Dmitry Antipov  <dmantipov@yandex.ru>

	Convenient macro to check whether the buffer is hidden.

	Fix a recently-introduced delete-process race condition.
	* callproc.c, process.h (record_kill_process):
	New function, containing part of the old call_process_kill.
	(call_process_kill): Use it.
	This does not change call_process_kill's behavior.
	* process.c (Fdelete_process): Use record_kill_process to fix a
	race condition that could cause Emacs to lose track of a child.

2012-12-06  Dmitry Antipov  <dmantipov@yandex.ru>

	Avoid code duplication between prev_frame and next_frame.
	* frame.c (candidate_frame): New function.  Add comment.

2012-12-06  Eli Zaretskii  <eliz@gnu.org>

	* callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
	fails, signal an error instead of continuing with an empty
	string.  (Bug#13079)
	Encode expanded temp file pattern before passing it to mkstemp or
	mktemp.

	* fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
	Encode the file name before passing it to dostounix_filename, in
	case it will downcase it (under w32-downcase-file-names).
	(Bug#12933)

2012-12-05  Paul Eggert  <eggert@cs.ucla.edu>

	Minor call-process cleanups.
	* callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
	at the same time as other platforms, to simplify analysis.
	No need for fd0_volatile since we have synch_process_fd.
	Avoid needless emacs_close; arg is always negative.

2012-12-04  Andreas Schwab  <schwab@linux-m68k.org>

	* callproc.c (Fcall_process): Fix specpdl nesting for asynchronous
	processes.

2012-12-04  Dmitry Antipov  <dmantipov@yandex.ru>

	* lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state

	and mouse_face_hidden members to a bitfields.
	* frame.h (struct frame): Remove set-but-not-used space_width member.
	(FRAME_SPACE_WIDTH): Remove.
	* nsterm.m, w32term.c, xterm.c: Adjust users.
	* termchar.h (struct tty_display_info): Remove set-but-unused se_is_so
	member.  Adjust users.  Convert term_initted, delete_in_insert_mode,
	costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
	members to a bitfields.

2012-12-03  Paul Eggert  <eggert@cs.ucla.edu>

	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.

	* bytecode.c, lisp.h (Qbytecode): Remove.
	No longer needed after 2012-11-20 interactive-p changes.

2012-12-03  Eli Zaretskii  <eliz@gnu.org>

	* xdisp.c (redisplay_window): If the cursor is visible, but inside

	Add comment.
	(save_excursion_restore): Adjust to match saved data structure.
	Use free_save_value to offload some work from GC.  Drop obsolete
	#if 0 code.

2012-12-03  Chong Yidong  <cyd@gnu.org>

	* fileio.c (Vauto_save_list_file_name): Doc fix.

	builds.
	(file_dialog_callback): Make it UINT_PTR.

	* w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
	with 64-bit builds.

	* w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
	(FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
	defined.

2012-12-02  Paul Eggert  <eggert@cs.ucla.edu>

	Fix xpalloc confusion after memory is exhausted.
	* alloc.c (xpalloc): Comment fix.
	* charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
	and signals an error, do not clear charset_table_size, as
	charset_table is still valid.
	* doprnt.c (evxprintf): Clear *BUF after freeing it.

	Use execve to avoid need to munge environ (Bug#13054).
	* callproc.c (Fcall_process):
	* process.c (create_process):
	Don't save and restore environ; no longer needed.
	* callproc.c (child_setup):
	Use execve, not execvp, to preserve environ.

2012-12-01  Paul Eggert  <eggert@cs.ucla.edu>

	* xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).

	* doc.c (Fdocumentation): Re-add handling of function-documentation,
	accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).

2012-11-29  Paul Eggert  <eggert@cs.ucla.edu>

	* callproc.c (Fcall_process): Don't misreport vfork failure.

2012-11-28  Paul Eggert  <eggert@cs.ucla.edu>

	* callproc.c (Fcall_process): Fix vfork portability problems.
	Do not assume that fd[0], count, filefd, and save_environ survive
	vfork.  Fix bug whereby wrong errno value could be reported for
	pipe failure.  Some minor cleanups, too, as follows.  Move buf and
	bufsize to the context where they're needed.  Change new_argv to
	be of type char **, as this is more convenient and avoids casts.
	(CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
	Now local constants, not macros.

2012-11-18  Kenichi Handa  <handa@gnu.org>

	* xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
	between bpos_covered and bpos_max.  This fixes cursor display when
	several display strings follow each other.

	* .gdbinit (pgx): If the glyph's object is a string, display the
	pointer to string data, rather than the value of the string object
	itself (which barfs under CHECK_LISP_OBJECT_TYPE).

	* indent.c (Fvertical_motion): If the starting position is covered
	by a display string, return to one position before that, to avoid
	overshooting it inside move_it_to.  (Bug#12930)

	(DIRENTRY_NONEMPTY): Remove.  All callers now assume it's nonzero.
	* makefile.w32-in (DIR_H): Remove.  All uses replaced with
