	* w32term.c (w32_read_socket) <WM_WINDOWPOSCHANGED>: Remove old
	and incorrect code.  Treat WM_WINDOWPOSCHANGED like WM_ACTIVATE
	and WM_ACTIVATEAPP.
	(w32fullscreen_hook): If the frame is visible, reset
	f->want_fullscreen flag after changing the frame size.  If the
	frame is not visible, set f->want_fullscreen to FULLSCREEN_WAIT.
	(Bug#13953)

	* emacs.c (main): Call syms_of_cygw32 on CYGWIN non-NTGUI builds
	too so that these builds can use Cygwin's file conversion
	functions.  (We've been building and linking cygw32.o all along
	and just not using it.)

	File synchronization fixes (Bug#13944).
	* Makefile.in (LIB_FDATASYNC): New macro.
	(LIBES): Use it.
	* conf_post.h (BSD_SYSTEM, BSD_SYSTEM_AHB): Remove; no longer needed.
	* fileio.c (Fwrite_region, write_region_inhibit_fsync):
	Don't worry about HAVE_FSYNC, since a substitute fsync is
	available if the system lacks one.
	(Fwrite_regin): Retry fsync if interrupted.

	* w32term.c (w32_read_socket): If the Emacs frame is being
39 40 41
	activated, call w32fullscreen_hook, to make sure the new frame

	* xdisp.c (init_iterator): Simplify because both character and byte
	positions are either specified or -1.  Add eassert.  Adjust comment.
46 47
	* window.c (Fscroll_other_window): Use SET_PT_BOTH because both
	character and byte positions can be obtained from marker.

	Include <sys/param.h> unconditionally, as that works elsewhere and
	is simpler here.  Include <sys/sysctl.h> if DARWIN_OS ||
	__FreeBSD__, not if BSD_SYSTEM, since it's needed only for Darwin
	and FreeBSD now.

	Adjust comment.
	(bidi_resolve_explicit_1, bidi_level_of_next_char): Adjust users.

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>.

2013-03-04  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.

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
	<http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00531.html>.
	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.
420
	(lock_file): Don't access freed storage.

	* 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)
808 809 810
	(try_scrolling): Scroll text up more if point is too close to ZV
	and inside the scroll margin.  This makes sure point is moved
	outside the scroll margin in these cases.

	(sxhash_float): Return EMACS_UINT, for consistency with the other

	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.

	Avoid encoding file names on MS-Windows when they need to be run

	downcase it even if w32-downcase-file-names is non-nil.

	[WINDOWSNT]: Downcase file names if w32-downcase-file-names is

	(Fsubstitute_in_file_name): [DOS_NT] Don't downcase environment

1060 1061 1062 1063 1064
	* 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.

1065 1066 1067

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.

	(emacs_readlinkat): New function, with much of the old

	* fileio.c: Use O_APPEND to append.
	This corresponds better to the natural interpretation of "append",

	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.

	Work around bug in CIFS and vboxsf file systems (Bug#13149).
	The bug was observed on Ubuntu operating inside a virtual machine,

	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.
	* lisp.h (move_gap): Remove prototype.
	* insdel.c (move_gap): Remove.
	(move_gap_both): Add eassert.
	* editfns.c (Ftranspose_regions): Tweak to use move_gap_both.
	* xml.c (parse_region): Likewise.
