2013-09-22  Paul Eggert  <eggert@cs.ucla.edu>

	Fix syntax.h bug introduced by recent INLINE change.
	syntax.h defined an extern inline function SYNTAX_ENTRY that was
	conditionally compiled one way in some modules, and a different
	way in others.  This doesn't work with extern inline functions,
	which must have the same definition in all modules, because the
	defining code might be shared across modules, depending on the
	implementation.  Symptoms reported by Martin Rudalics in:
	http://lists.gnu.org/archive/html/emacs-devel/2013-09/msg00414.html
	* regex.c, syntax.c (SYNTAX_ENTRY_VIA_PROPERTY): Remove.
	(SYNTAX, SYNTAX_ENTRY, SYNTAX_WITH_FLAGS): New macros,
	overriding the corresponding functions in syntax.h.
	* syntax.h (syntax_property_entry, syntax_property_with_flags)
	(syntax_property): New inline functions.
	(SYNTAX_ENTRY, SYNTAX_WITH_FLAGS, SYNTAX):
	Rewrite in terms of these new functions.

	* dired.c (directory_files_internal): Use multibyte_chars_in_text,
	not chars_in_text, whose result depends on the multibyteness of
	the current buffer.  (Bug#15426)

2013-09-20  Paul Eggert  <eggert@cs.ucla.edu>

	Port recent change to hosts where pointers aren't 'long'.
	* xterm.c (x_send_scroll_bar_event, x_scroll_bar_to_input_event):
	Don't assume that pointers are the same width as 'long'.
	Add a compile-time check that a pointer fits into two X slots.

	A simpler, centralized INLINE.
	* conf_post.h (INLINE): Define only if not already defined.
	This allows us to use a single INLINE, defined by one file
	per executable.
	* emacs.c (INLINE): Define it.
	Also, include category.h, charset.h, composite.h, dispextern.h,
	syntax.h, systime.h, so that their INLINE definitions are expanded
	properly for Emacs.
	* blockinput.h, keyboard.c (BLOCKINPUT_INLINE):
	* buffer.h, buffer.c (BUFFER_INLINE):

	Emacs has been using fd_set as a portability layer for some time.
	* sysselect.h (FD_SETSIZE): Rename from MAXDESC.  All uses changed.
	(SELECT_TYPE): Remove.  All uses changed to fd_set.
	(fd_set) [!FD_SET]: New typedef.

	Simplify EMACS_TIME-related code.
	This portability layer is no longer needed, since Emacs has been
	using struct timespec as a portability layer for some time.
	* atimer.h, buffer.h, dispextern.h, xgselect.h:
	Include <time.h> rather than "systime.h"; that's all that's needed now.

	that's all that's needed now.
	* systime.h (EMACS_TIME): Remove.  All uses changed to struct timespec.

	* xterm.h (FONT_TYPE_FOR_UNIBYTE, FONT_TYPE_FOR_MULTIBYTE:)
	* nsterm.h (FONT_TYPE_FOR_UNIBYTE, FONT_TYPE_FOR_MULTIBYTE):
	Remove the leftovers.
	* gtkutil.c (toplevel): Do not declare Qxft but include
	font.h to do so.
	* image.c (toplevel): Do not declare Vlibrary_cache because
	it's already done in lisp.h.

2013-08-27  Dmitry Antipov  <dmantipov@yandex.ru>

	* lisp.h (Mouse_HLInfo): Move from here...
	* dispextern.h (Mouse_HLInfo): ...to here and offload lisp.h.

2013-08-26  Stefan Monnier  <monnier@iro.umontreal.ca>

	* lread.c (substitute_object_recurse): Handle hash-tables as well
	(bug#15190).

2013-08-26  Paul Eggert  <eggert@cs.ucla.edu>

	Fix unlikely core dump in init_tty, and simplify terminfo case.
	* term.c (init_tty) [TERMINFO]: Fix check for buffer overrun.
	The old version incorrectly dumped core if malloc returned a
	buffer containing only non-NUL bytes.
	(init_tty): Do not allocate or free termcap buffers; the
	struct does that for us now.
	* termchar.h (TERMCAP_BUFFER_SIZE) [!TERMINFO]: New constant.
	(struct tty_display_info): Define members termcap_term_buffer and
	termcap_strings_buffer only if !TERMINFO, since terminfo doesn't
	use them.  Allocate them directly in struct rather than indirectly
	via a pointer, to simplify init_tty.

	* frame.c (check_minibuf_window): Initialize 'window' properly,
	so that Emacs reliably aborts later if 'window' is not initialized.

2013-08-26  Jan Djärv  <jan.h.d@swipnet.se>

	* gtkutil.c (xg_initialize): Set gtk-menu-bar-accel to "" instead

	* frame.c (check_minibuf_window): New function.
	(delete_frame, Fmake_frame_invisible, Ficonify_frame):

2013-08-26  Dmitry Antipov  <dmantipov@yandex.ru>

	* window.h (struct window): Replace last_cursor with last_cursor_vpos
	because this is the only last cursor data we need to keep and consult.
	* window.c (replace_window, set_window_buffer, Fsplit_window_internal):
	* xdisp.c (mark_window_display_accurate_1, try_cursor_movement):
	Adjust users.

2013-08-26  Dmitry Antipov  <dmantipov@yandex.ru>

	Fix recovering from possible decompression error.
	Since insert_from_gap doesn't always move point, we can't use PT as
	the position where the partially decompressed data ends, and
	should count how many bytes was produced so far.
	* decompress.c (struct decompress_unwind_data): Add nbytes member.
	(unwind_decompress): Really delete partially uncompressed data.
	(Fzlib_decompress_region): Take decompressed data size into account.

2013-08-26  Dmitry Antipov  <dmantipov@yandex.ru>

	* category.c (init_category_once):
	* character.c (syms_of_character):
	* coding.c (syms_of_coding):
	* xdisp.c (syms_of_xdisp): ...and omit it here.

2013-08-24  Eli Zaretskii  <eliz@gnu.org>

	* xdisp.c (get_next_display_element): Don't apply to characters
	from a display vector the logic of setting it->end_of_box_run_p
	suitable for characters from a buffer.  (Bug#15175)

	* w32.c (fdutimens): Call 'utime', which is implemented on w32.c
	to handle directories, rather than '_utime' which doesn't.
	(Bug#15176)

2013-08-24  Jan Djärv  <jan.h.d@swipnet.se>

	* gtkutil.c (x_wm_set_size_hint): Don't set hints when maximized
	or fullscreen (Bug#14627).

2013-08-24  Paul Eggert  <eggert@cs.ucla.edu>

	System-dependent integer overflow fixes.
	* process.c (Fset_process_window_size): Signal an error if
	the window size is outside the range supported by the lower level.
	* sysdep.c (set_window_size): Return negative on error,
	nonnegative on success, rather than -1, 0, 1 on not in system,
	failure, success.  This is simpler.  Caller changed.
	(serial_configure): Remove unnecessary initialization of local.
	(procfs_get_total_memory) [GNU_LINUX]: Don't assume system memory
	size fits in unsigned long; this isn't true on some 32-bit hosts.
	Avoid buffer overrun if some future version of /proc/meminfo has a
	variable name longer than 20 bytes.
	(system_process_attributes) [__FreeBSD__]:
	Don't assume hw.availpages fits in 'int'.

2013-08-23  Paul Eggert  <eggert@cs.ucla.edu>

	Don't let very long directory names overrun the stack.
	Fix some related minor problems involving "//", vfork.
	* callproc.c (encode_current_directory): New function.
	(call_process): Don't append "/"; not needed.
	* fileio.c (file_name_as_directory_slop): New constant.
	(file_name_as_directory): Allow SRC to be longer than SRCLEN;
	this can save the caller having to alloca.
	(Ffile_name_as_directory, Fdirectory_file_name, Fexpand_file_name):
	Use SAFE_ALLOCA, not alloca.
	(directory_file_name, Fexpand_file_name): Leave leading "//"
	alone, since it can be special even on POSIX platforms.
	* callproc.c (call_process):
	* process.c (Fformat_network_address):
	* sysdep.c (sys_subshell):
	Use encode_current_directory rather than rolling our own.
	(create_process): No need to encode directory; caller does that now.
	* process.h (encode_current_directory): New decl.
	* sysdep.c (sys_subshell): Work even if vfork trashes saved_handlers.
	Rework to avoid 'goto xyzzy;'.

2013-08-23  Eli Zaretskii  <eliz@gnu.org>

	* xdisp.c (handle_face_prop): If the default face was remapped use
	the remapped face for strings from prefix properties.  (Bug#15155)

2013-08-23  Dmitry Antipov  <dmantipov@yandex.ru>

	Minor cleanup for redisplay interface and few related functions.
	* frame.h (enum text_cursor_kinds): Move from here...
	* dispextern.h (enum text_cursor_kinds): ...to here.
	(toplevel): Drop unnecessary declarations.
	(struct redisplay_interface): Use bool and enum text_cursor_kinds
	in update_window_end_hook and draw_window_cursor functions.

	* xterm.c (x_update_window_end, x_draw_window_cursor):
	* xdisp.c (display_and_set_cursor, update_window_cursor)
	(update_cursor_in_window_tree, x_update_cursor): Use bool and
	enum text_cursor_kinds where appropriate.

2013-08-23  Dmitry Antipov  <dmantipov@yandex.ru>

	Redesign redisplay interface to drop updated_row and updated_area.
	* dispextern.h (updated_row, updated_area): Remove declaration.
	(struct redisplay_interface): Pass glyph row and row area parameters
	to write_glyphs, insert_glyphs and clear_end_of_line functions.

	Adjust prototypes.
	* dispnew.c (updated_row, updated_area): Remove.
	(redraw_overlapped_rows, update_window_line): Adjust user.
	(update_marginal_area, update_text_area): Likewise.  Pass updated row
	as a parameter.  Prefer enum glyph_row_area to int where appropriate.
	* xdisp.c (x_write_glyphs, x_insert_glyphs, x_clear_end_of_line):
	Adjust users.

2013-08-22  Paul Eggert  <eggert@cs.ucla.edu>

2013-08-21  Paul Eggert  <eggert@cs.ucla.edu>

	* callproc.c: Fix race that killed background processes (Bug#15144).
	(call_process): New arg TEMPFILE_INDEX.  Callers changed.
	Record deleted process-id in critical section, not afterwards.
	Don't mistakenly kill process created by a call-process invocation
	that discards output and does not wait.

2013-08-21  Dmitry Antipov  <dmantipov@yandex.ru>

	Fix compilation with GC_MARK_STACK == GC_USE_GCPROS_AS_BEFORE
	and GC_MARK_STACK == GC_USE_GCPROS_CHECK_ZOMBIES.
	* alloc.c (toplevel): Remove unnecessary nested #if...#endif.
	(mark_maybe_object) [!GC_MARK_STACK]: Define to emacs_abort

2013-08-21  Paul Eggert  <eggert@cs.ucla.edu>

	* process.c (allocate_pty) [PTY_OPEN]: Set fd's FD_CLOEXEC flag.
	We can't portably rely on PTY_OPEN doing that, even if
	it calls posix_openpt with O_CLOEXEC.

2013-08-20  Kenichi Handa  <handa@gnu.org>

	* character.c (string_char): Improve commentary.

2013-08-20  Paul Eggert  <eggert@cs.ucla.edu>

	* image.c (SIGNATURE_DIGESTSIZE): Remove.
	(struct animation_cache): Make signature a flexible array member.

	from future changes to ImageMagick.

2013-08-19  Paul Eggert  <eggert@cs.ucla.edu>

	* image.c: Shrink memory needed for animation cache.
	(SIGNATURE_DIGESTSIZE): New constant.
	(struct animation_cache): Make 'signature' a fixed size array of bytes.
	(imagemagick_create_cache): Copy the signature.  This saves
	several KB of memory that ImageMagick wastes per signature.
	Don't bother updating the update_time, as the caller does that now.
	(imagemagick_prune_animation_cache): Don't destroy the signature, as
	it's a fixed size struct member now.
	(imagemagick_get_animation_cache): Always destroy the signature,
	as it's now imagemagick_create_cache's responsibility to copy it.
	Avoid duplicate calls to strcmp and to imagemagick_create_cache,
	and use memcmp rather than strcmp.
	eassert that ImageMagick returns a signature of the specified length.

2013-08-19  Lars Magne Ingebrigtsen  <larsi@gnus.org>

	* image.c (imagemagick_get_animation_cache): Don't segfault on

	(imagemagick_get_animation_cache): Fix memory leak.

2013-08-19  Paul Eggert  <eggert@cs.ucla.edu>

	* image.c: Fix animation cache signature memory leak.
	Fix some other minor performance problems while we're at it.
	(imagemagick_create_cache): Clear just the members that
	need clearing.  Don't set update_time, as caller does that now.
	(imagemagick_prune_animation_cache, imagemagick_get_animation_cache):
	Simplify by using pointer-to-pointer instead of a prev pointer.
	(imagemagick_prune_animation_cache): Use make_emacs_time rather
	than EMACS_TIME_FROM_DOUBLE, and DestroyString rather than free.
	(imagemagick_get_animation_cache): Don't xstrdup the image signature;
	it's already a copy.  Free the signature probe unless it's cached.

	* process.c (handle_child_signal): Fix crash; deleted pid (Bug#15106).
	This was introduced by my 2013-08-12 fix for Bug#15035.

2013-08-19  Dmitry Antipov  <dmantipov@yandex.ru>

	* image.c (imagemagick_create_cache, imagemagick_get_animation_cache)

	of zlib_initialized according to the results of calling
	init_zlib_functions.

2013-08-16  Lars Magne Ingebrigtsen  <larsi@gnus.org>

	* image.c: Implement an ImageMagick per-image cache.
	(imagemagick_get_animation_cache): Fix a double-free error.

	everything else.  Optimise for the common case.

2013-08-16  Xue Fuqiao  <xfq.free@gmail.com>

	* buffer.c (syms_of_buffer) <buffer-undo-list>: Doc fix.

	have sub-images that are bigger than the main image, but just crop
	them.

2013-08-15  Jan Djärv  <jan.h.d@swipnet.se>

	* nsmenu.m (menuWillOpen:): Fix preprocessor test (Bug#15001).

2013-08-15  Lars Magne Ingebrigtsen  <larsi@gnus.org>

	* image.c (imagemagick_compute_animated_image): Respect the GIF
	disposal methods.

2013-08-15  Ken Brown  <kbrown@cornell.edu>

	* emacs.c (main): Update comment about G_SLICE_ALWAYS_MALLOC.

	instead of int.

2013-08-15  Dmitry Antipov  <dmantipov@yandex.ru>

	Fix infinite frame selection loop (Bug#15025).
	* frame.c (delete_frame): Prefer fast ad-hoc loop to next_frame.

2013-08-15  Eli Zaretskii  <eliz@gnu.org>

	* xdisp.c (compute_window_start_on_continuation_line):
	When WORD_WRAP is in effect, use move_it_to instead of move_it_by_lines
	to make sure we end up setting the window start at the leftmost
	visible character of the display line.  This avoids funky
	horizontal shifting because the window start is not kept on the
	same position.  (Bug#15090)
	(next_element_from_display_vector): Support 'box' face attribute
	in the face definitions of a display vector.  (Bug#15099)

2013-08-15  Lars Magne Ingebrigtsen  <larsi@gnus.org>

	* image.c (imagemagick_compute_animated_image): Implement animated
	images (bug#14700).
	(imagemagick_compute_animated_image): Fix some compilation
	warnings.  Implement a very simple cache to make the animation
	usable at all, but it should be replaced with a per-image cache.

	(tty_free_frame_resources, delete_tty): Prefer eassert to emacs_abort.
	* image.c (make_image_cache): For struct image_cache, prefer xmalloc
	to xzalloc and so avoid redundant call to memset.
	* xterm.c (x_term_init): Avoid unnecessary initializations of dpyinfo
	members because it is allocated with xzalloc and so already zeroed.

2013-08-14  Ken Brown  <kbrown@cornell.edu>

	* gmalloc.c (memalign) [CYGWIN]: Rename to emacs_memalign
	(Bug#15094).

	prefer SSDATA to SDATA to avoid warnings.

2013-08-14  Dmitry Antipov  <dmantipov@yandex.ru>

	Cleanup window fringes, margins and scroll bars adjustments.
	* window.c (set_window_fringes, set_window_margins)

	bar was actually changed, and mention this in docstring.

2013-08-13  Paul Eggert  <eggert@cs.ucla.edu>

	* decompress.c: Minor simplifications.
	(Fzlib_decompress_region): Don't bother verifying
	that avail_out <= UINT_MAX, as that was confusing.
