System-dependent integer overflow fixes.

[bpt/emacs.git] / src / ChangeLog

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)

	(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.
	(x_write_glyphs, x_insert_glyphs, x_clear_end_of_line):
	Adjust prototypes.
	* dispnew.c (updated_row, updated_area): Remove.
	(redraw_overlapped_rows, update_window_line): Adjust user.

	Fix compilation with GC_MARK_STACK == GC_USE_GCPROS_AS_BEFORE
	and GC_MARK_STACK == GC_USE_GCPROS_CHECK_ZOMBIES.

	(mark_maybe_object) [!GC_MARK_STACK]: Define to emacs_abort
	to shut up compiler in mark_object.
	(dump_zombies): Convert to global and add EXTERNALLY_VISIBLE.

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.
	All uses changed.  This is a tad slower but may insulate us better
	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
	each invocation.
	(imagemagick_get_animation_cache): Revert to previous definition
	so that it actually works.  But keep the memory leak fix.
	(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)

	static heap if ENABLE_CHECKING is defined.
	(max_bss_sbrk_ptr): New variable.
	(bss_sbrk): Use it.
	(report_sheap_usage): Report maximum static heap usage instead of
	ending static heap usage.

2013-08-17  Eli Zaretskii  <eliz@gnu.org>

	* decompress.c (Fzlib_available_p) [WINDOWSNT]: Update the value
	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.
	(imagemagick_load_image): Remove the ping_wand code, which only
	apparently saved time on invalid animated images, and slowed down
	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.

	them.

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

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.

	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).

	* xdisp.c (adjust_window_ends): Move duplicated code to new function.
	(try_window, try_window_reusing_current_matrix, try_window_id): Use it.

	* decompress.c: Minor simplifications.
	(Fzlib_decompress_region): Don't bother verifying

	(window_frozen_p): New function.
	(redisplay_window): Use it.

2013-08-12  Paul Eggert  <eggert@cs.ucla.edu>

	Fix some fd issues when running subprocesses (Bug#15035).
	Fix bugs that can leak files or file descriptors on errors.
	Don't unlink open temp files, as that's hard for users to diagnose
	when things go awry (e.g., temp disk exhausted).
	Don't bother to lock temp files.  Check for invalid recursion.
	* callproc.c (synch_process_fd): Remove.  All uses removed.
	(synch_process_tempfile): New var or macro.
	(CALLPROC_STDOUT, CALLPROC_STDERR, CALLPROC_PIPEREAD, CALLPROC_FDS):
	New constants.
	(record_kill_process): New arg, the temp name.  All callers changed.
	(delete_temp_file): Now just a simple wrapper around unlink.
	(call_process_kill): New arg, the call_process_fd array.
	Close them all.  Clear synch_process_pid.  Remove the temp file,
	or arrange for it to be removed.
	(call_process_cleanup) [MSDOS]: Arg no longer contains file name;
	that's been moved to synch_process_tempfile.  Caller changed.
	Do not remove the tempfile; that's now call_process_kill's
	responsibility.
	(call_process_cleanup) [!MSDOS]: Do not record unwind-protect for
	call_process_kill; the caller now does that.
	(call_process_cleanup): Do not close the process fd; that's now
	call_process_kill's responsibility.
	(Fcall_process): Implement via new function call_process, which
	has most of the old body of Fcall_process, but with a different API.
	(call_process): New function that does not open or close filefd if
	it is nonnegative.  Record which fds need to be closed, and let
	call_process_kill close (and remove the tempfile, on MSDOS) on error.
	Signal an error if invoked recursively (could be done via a hook).
	Simplify creation of the tempfile in the MSDOS case.
	Don't create the output file until after checking for the executable.
	Report any failure to open /dev/null.
	Don't open /dev/null for writing twice; once is enough.
	Don't create pipe if all output is being discarded or sent to file.
	Don't worry about setting up the coding system or reading from the
	pipe if all output is being discarded.
	Hoist fd_error local into top level, to lessen block nesting.
	Don't record deleted pid here; now done by Fcall_process_region.
	(Fcall_process) [MSDOS]: Report mktemp failure immediately,
	and note its success in synch_process_tempfile.
	Do not leak resources when child_setup fails.
	(Fcall_process) [!MSDOS && !WINDOWSNT]: Remove duplicate assignment
	to child_errno.  Remove unnecessary close of fd0; it's close-on-exec.
	(create_temp_file): Now returns open fd, with an additional
	Lisp_Object * argument to return the name.  All callers changed.
	Do not close the file; rewind it instead, and leave it open for
	the caller.  Do not lock the temp file.  Unwind-protect the file
	and the file-descriptor.
	(Fcall_process_region): If the input is /dev/null, unwind-protect it.
	If an asynchrounous process, record it here, not in call_process.
	(syms_of_callproc) [MSDOS]: Initialize synch_process_tempfile.
	* eval.c (set_unwind_protect): New function.
	* fileio.c (write_region): New function, generalized from the
	old Fwrite_region.  Do not lock temp files.
	(Fwrite_region): Use it.
	* lisp.h (set_unwind_protect, write_region): New decls.
	* process.c: Include <verify.h>.
	(make_process): Mark fds as initially closed.

	All uses changed.
	(close_process_fd): New function.
	(SUBPROCESS_STDIN, WRITE_TO_SUBPROCESS, READ_FROM_SUBPROCESS)
	(SUBPROCESS_STDOUT, READ_FROM_EXEC_MONITOR, EXEC_MONITOR_OUTPUT):
	New constants.  Verify that their number matches PROCESS_OPEN_FDS.
	(create_process, create_pty, Fmake_serial_process)
	(server_accept_connection): Record which fds need to be closed,
	and let deactivate_process close them.
	(Fmake_network_process): Do not discard the unwind-protect
	until it's safe to do so.
	(deactivate_process): Close the fds opened by create_process etc.
	(Fprocess_send_eof): Adjust to new way of recording open fds.
	Report an error if /dev/null can't be opened, instead of aborting.
	* process.h (PROCESS_OPEN_FDS): New constant.
	(struct Lisp_Process): New member open_fds.
	(record_kill_process, record_deleted_pid): Adjust signatures.
	(record_deleted_pid): Move decl here ...
	* syswait.h (record_deleted_pid): ... from here.

2013-08-11  Paul Eggert  <eggert@cs.ucla.edu>

	* decompress.c: Fix bugs with large buffers and weird inputs.
	Tune a bit.  Reindent as per usual Emacs style.
	(BUFFER_SIZE): Remove.
	(Fdecompress_gzipped_region): Do not mishandle input buffers with
	more than UINT_MAX bytes.  Decompress into the gap instead of into
	an auto buffer, as this should avoid copying.  Return nil if
	'inflate' returns Z_NEED_DICT, as we have no dictionary.  Do not
	set immediate_quit; we shouldn't trust zlib code that much.

2013-08-11  Lars Magne Ingebrigtsen  <larsi@gnus.org>

2013-08-02  Dmitry Antipov  <dmantipov@yandex.ru>

	Fix X GC leak in GTK and raw (no toolkit) X ports.
	* xterm.c (x_free_frame_resources): If white and black relief
	GCs are allocated, always free them here.
	* xfns.c (x_make_gc): Omit redundant initialization.
	* widget.c (create_frame_gcs): Remove the leftover.
	(EmacsFrameDestroy): Do nothing because all GCs are now freed
	in x_free_frame_resources.

2013-08-02  Jan Djärv  <jan.h.d@swipnet.se>

	* nsterm.m (windowWillResize:toSize:): Only change title if
	! maximizing_resize && FULLSCREEN_NONE (Bug#15005).  strdup title before
	modifying it.
	(viewDidEndLiveResize): New method.

	* nsterm.h (EmacsView): Add maximizing_resize, put it and old_title
	inside NS_IMPL_COCOA.

2013-08-02  Dmitry Antipov  <dmantipov@yandex.ru>

	* insdel.c (adjust_after_replace, replace_range, del_range_2):
	Do not check whether undo is enabled because record_insert and
	record_delete does that themselves.

2013-08-02  Dmitry Antipov  <dmantipov@yandex.ru>

	* xterm.h (struct x_output) [HAVE_X_I18N]: Remove xic_base_fontname
	member which is not really used any more.

2013-08-01  Paul Eggert  <eggert@cs.ucla.edu>

	* fileio.c, fns.c (merge): Move extern decl from here ...
	* lisp.h (merge): ... to here.

2013-08-01  Dmitry Antipov  <dmantipov@yandex.ru>

	Fix last font-related change.
	* w32font.h (w32font_list_internal, w32font_match_internal):
	Fix prototype.
	* w32uniscribe.c (uniscribe_list, uniscribe_match):
	(uniscribe_list_family): Adjust to match font API change.
	MS-Windows breakage reported by Juanma Barranquero <lekktu@gmail.com>
	at http://lists.gnu.org/archive/html/emacs-devel/2013-08/msg00006.html.

2013-08-01  Dmitry Antipov  <dmantipov@yandex.ru>

	* frame.h (FRAME_MOUSE_UPDATE):
	* nsterm.m (ns_frame_up_to_date): Omit redundant check
	whether hlinfo->mouse_face_mouse_frame is non-NULL.

2013-08-01  Dmitry Antipov  <dmantipov@yandex.ru>

	Avoid redundant Lisp_Object <-> struct frame conversions in font API.
	* font.h (struct font_driver): Change list, match, and list_family
	functions to accept struct frame * as first arg.
	* font.c (font_score, font_compare, font_sort_entities): Remove
	prototypes.
	(font_sort_entities, font_list_entities, font_select_entity):
	(font_find_for_lface, Flist_fonts, Ffont_family_list): Adjust to
	match font API change.
	* xfont.c (xfont_list, xfont_match, xfont_list_family):
	* ftfont.c (ftfont_list, ftfont_match, ftfont_list_family):
	* ftxfont.c (ftxfont_list, ftxfont_match):
	* xftfont.c (xftfont_list, xftfont_match):
	* nsfont.m (nsfont_list, nsfont_match, nsfont_list_family):
	* w32font.c (w32font_list, w32font_match, w32font_list):
	(w32font_list_internal, w32_font_match_internal): Likewise.
	* xfaces.c (Fx_family_fonts): Adjust user.

2013-08-01  Dmitry Antipov  <dmantipov@yandex.ru>

	Do not use pure Xism x_wm_set_icon_position in non-X ports.
	* frame.c (x_set_frame_parameters): Call to x_wm_set_icon_position
	only if HAVE_X_WINDOWS is in use.
	* frame.h (x_set_frame_parameters): Move under HAVE_X_WINDOWS.
	* nsterm.m (x_wm_set_icon_position): Remove no-op.
	* w32term.c (x_wm_set_icon_position): Likewise.
	* w32fns.c (x_icon): Adjust user.

2013-08-01  Dmitry Antipov  <dmantipov@yandex.ru>

	* xterm.c (last_mouse_press_frame): Remove the
	leftover which is not really used any more.
	(handle_one_xevent, syms_of_xterm): Adjust users.
	(x_flush): Call XFlush once per each X display, not frame.
	This is better because this code always unconditionally skips
	non-X frames in Vframe_list and issues the only	XFlush if we
	have more than one X frame on the same X display.
	(any_help_event_p, x_draw_glyph_string_background, x_display_ok):
	Use bool for booleans.
	(x_draw_glyph_string_background, cvt_string_to_pixel):
	(cvt_pixel_dtor): Drop unnecessary prototypes.
	* xterm.h (x_display_ok): Adjust prototype.

2013-07-31  Dmitry Antipov  <dmantipov@yandex.ru>

	Drop unnecessary functions that deals with frame pixel size.
	* frame.h, msdos.h, w32term.h, xterm.h (x_pixel_width)
	(x_pixel_height): Drop prototypes.
	* msdos.c, nsfns.m, w32fns.c, xfns.c (x_pixel_width)
	(x_pixel_height): Drop implementations.
	* frame.c (Fframe_pixel_height): Use FRAME_PIXEL_HEIGHT
	which should be always valid for window frame.
	(Frame_pixel_width): Likewise with FRAME_PIXEL_WIDTH.
	* w32menu.c (Fx_popup_dialog):
	* xmenu.c (Fx_popup_dialog): Likewise for both.

2013-07-31  Dmitry Antipov  <dmantipov@yandex.ru>

	* frame.c (Fmake_terminal_frame): Use store_in_alist to setup
	frame parameters and call to Fmodify_frame_parameters just once.
	(Fset_frame_height, Fset_frame_width): Mention nil frame in docstring.
	(Fset_frame_size, Fset_frame_position): Use decode_live_frame
	and mention nil frame in docstring.

2013-07-31  Dmitry Antipov  <dmantipov@yandex.ru>

	* frame.c (make_frame, x_set_frame_parameters): Use bool for boolean.
	(x_figure_window_size): Likewise.  Adjust to return long.
	(syms_of_frame): Do not DEFSYM Qterminal_live_p.
	(toplevel): Move Qterminal_live_p to...
	* terminal.c (toplevel): ...here, make it static, and...
	(syms_of_terminal): ...DEFSYM here.
	* frame.h (Qterminal_live_p): Remove declaration.
	(make_frame, x_figure_window_size): Adjust prototype.
	* nsfns.m (Fx_create_frame): Use long for window flags.

2013-07-30  Paul Eggert  <eggert@cs.ucla.edu>

	Fix tempfile bug on platforms lacking mkostemp and mkstemp (Bug#14986).
	* callproc.c (create_temp_file) [! (HAVE_MKOSTEMP || HAVE_MKSTEMP)]:
	Do not assume that emacs_close (INT_MAX) is a no-op.

2013-07-30  Dmitry Antipov  <dmantipov@yandex.ru>

	* xfaces.c (make_face_cache): For struct face_cache, prefer
	xmalloc to xzalloc and so avoid redundant call to memset.
	(Finternal_set_lisp_face_attribute): Fix comment typo and style.

2013-07-30  Dmitry Antipov  <dmantipov@yandex.ru>

	* fringe.c (draw_window_fringes, update_window_fringes)
	(compute_fringe_widths):
	* w32term.c (x_draw_glyph_string):
	* window.c (candidate_window_p, Frecenter):

	* xsettings.c (xft_settings_event):
	* xterm.c (x_draw_glyph_string, x_had_errors_p):
	Use bool for booleans.  Adjust style and comments where
	appropriate.
	* dispextern.h (draw_window_fringes, update_window_fringes)
	(compute_fringe_widths):
	* xterm.h (x_had_errors_p): Adjust prototype.

2013-07-30  Dmitry Antipov  <dmantipov@yandex.ru>

	* frame.c (Fmodify_frame_parameters): Always check 2nd arg with
	CHECK_LIST.  Rewrite the loop to avoid useless local variable.

2013-07-29  Dmitry Antipov  <dmantipov@yandex.ru>

	* fns.c (toplevel): Remove comment before Fsafe_length because
	it checks for QUIT.

2013-07-28  Paul Eggert  <eggert@cs.ucla.edu>

	* frame.c (delete_frame): Avoid unnecessary 'this_f' test (Bug#14970).

2013-07-28  Eli Zaretskii  <eliz@gnu.org>

	* w32fns.c (w32_wnd_proc) <WM_IME_STARTCOMPOSITION>: Make sure the
	frame which got the message is still alive, before dereferencing
	its pointer.  (Bug#14970)

	* frame.c (delete_frame): Test "this" frame's minibuffer window to
	be a live window, before using it as such.  (Bug#14970)

2013-07-27  Eli Zaretskii  <eliz@gnu.org>

	* w32term.c (w32_read_socket) <WM_KILLFOCUS>: Call
	w32_detect_focus_change instead of doing part of its job by hand.
	This fixes the problem whereby FOCUS_OUT events were not sent to
	the event queue.

2013-07-26  Eli Zaretskii  <eliz@gnu.org>

	* process.c (Fprocess_list): Doc fix.

	* w32term.c (w32_read_socket) <WM_EMACS_PAINT>: Warn about frame
	being re-exposed only if it didn't ask to become visible.
	<WM_SIZE>: Under SIZE_RESTORED, only set the frame visible if it
	was previously iconified.  (Bug#14841)
	(x_iconify_frame): Mark the frame iconified.

2013-07-26  Paul Eggert  <eggert@cs.ucla.edu>

	Fix minor problems found by static checking.
	* eval.c (get_backtrace_frame, backtrace_eval_unrewind): Now static.
	(backtrace_eval_unrewind): ';' -> '{}' to pacify GCC.

2013-07-26  Stefan Monnier  <monnier@iro.umontreal.ca>

	* eval.c (set_specpdl_old_value): New function.
	(unbind_to): Minor simplification.
	(get_backtrace_frame): New function.
	(Fbacktrace_frame): Use it.  Add `base' argument.
	(backtrace_eval_unrewind, Fbacktrace_eval): New functions.
	(syms_of_eval): Export backtrace-eval.
	* xterm.c (x_focus_changed): Simplify.

2013-07-25  Paul Eggert  <eggert@cs.ucla.edu>

	* fileio.c (Finsert_file_contents): Avoid double-close (Bug#14936).

2013-07-24  Eli Zaretskii  <eliz@gnu.org>

	* xdisp.c (redisplay_window): Instead of moving point out of
	scroll margin, reject the force_start method, and try scrolling
	instead.  (Bug#14780)

2013-07-24  Ken Brown  <kbrown@cornell.edu>

	* alloc.c (make_save_ptr): Define if HAVE_NTGUI is defined
	(Bug#14944).

2013-07-24  Paul Eggert  <eggert@cs.ucla.edu>

	* eval.c (Fprogn): Do not check that BODY is a proper list.
	This undoes the previous change.  The check slows down the
	interpreter, and is not needed to prevent a crash.  See
	<http://lists.gnu.org/archive/html/emacs-devel/2013-07/msg00693.html>.

2013-07-23  Glenn Morris  <rgm@gnu.org>

	* Makefile.in ($(etc)/DOC, temacs$(EXEEXT)): Ensure etc/ exists.

2013-07-23  Paul Eggert  <eggert@cs.ucla.edu>

	Port to GNU/Linux systems with tinfo but not ncurses.
	* dispnew.c (init_display): Depend on USE_NCURSES, not GNU_LINUX,
	to decide whether ncurses is being used.  Without this change,
	GCC complains about tgetent not being declared, on a system
	that has tinfo installed but ncurses not installed.

	* eval.c (Fprogn): Check that BODY is a proper list.

	Tune UNEVALLED functions by using XCAR instead of Fcar, etc.
	* data.c (Fsetq_default):
	* eval.c (Fif, Fcond, Fprog1, Fsetq, Fquote, Ffunction, Fdefvar)
	(Fdefconst, FletX, Flet, Fwhile, Fcatch, Funwind_protect)
	(Fcondition_case):
	Tune by taking advantage of the fact that ARGS is always a list
	when a function is declared to have UNEVALLED args.

	* emacsgtkfixed.c: Port to GCC 4.6.
	GCC 4.6 complains about -Wunused-local-typedefs, introduced in 4.7.

2013-07-23  Juanma Barranquero  <lekktu@gmail.com>

	* callproc.c (child_setup)[!WINDOWSNT]: Move exec_errno and pid
	here to silence compiler warnings.

2013-07-22  Paul Eggert  <eggert@cs.ucla.edu>

	* sysdep.c (frame) [__FreeBSD__]: #define to freebsd_frame
	when including <sys/user.h>, to prevent Sparc/ARM machine/frame.h
	from messing up Emacs's 'struct frame' (Bug#14923).

2013-07-21  Paul Eggert  <eggert@cs.ucla.edu>

	* alloc.c (make_save_ptr_ptr): Define this function.
	It was inadvertently omitted.  It's needed only if
	HAVE_MENUS && ! (USE_X_TOOLKIT || USE_GTK).

2013-07-21  Jan Djärv  <jan.h.d@swipnet.se>

	* nsterm.m (sendEvent:): Skip mouse moved if no dialog and no Emacs
	frame have focus (Bug#14895).

2013-07-21  Paul Eggert  <eggert@cs.ucla.edu>

	Avoid vfork-related deadlock more cleanly.
	* callproc.c (child_setup): When the child's exec fails, output
	the program name, as that's more useful.  Use O_NONBLOCK to avoid
	deadlock.
	* process.c (create_process_1): Remove; no longer needed.
	(create_process): Remove timer hack; no longer needed, now that
	the child avoids deadlock.

2013-07-20  Glenn Morris  <rgm@gnu.org>

	* image.c (Fimage_flush): Fix doc typo.

2013-07-20  Paul Eggert  <eggert@cs.ucla.edu>

	Fix array bounds violation when pty allocation fails.
	* process.c (PTY_NAME_SIZE): New constant.
	(pty_name): Remove static variable; it's now auto.
	(allocate_pty): Define even if !HAVE_PTYS; that's simpler.
	Take pty_name as an arg rather than using a static variable.
	All callers changed.
	(create_process): Recover pty_flag from process, not from volatile local.
	(create_pty): Stay inside array even when pty allocation fails.
	(Fmake_serial_process): Omit unnecessary initializaiton of pty_flag.

	* lread.c (Fload): Avoid initialization only when lint checking.
	Mention that it's needed only for older GCCs.

2013-07-20  Kenichi Handa  <handa@gnu.org>

	* coding.c (CODING_ISO_FLAG_LEVEL_4): New macro.
	(decode_coding_iso_2022): Check the single-shift area.  (Bug#8522)

2013-07-20  Andreas Schwab  <schwab@linux-m68k.org>

	* lread.c (Fload): Avoid uninitialized warning.

2013-07-19  Paul Eggert  <eggert@cs.ucla.edu>

	Fix some minor file descriptor leaks and related glitches.
	* filelock.c (create_lock_file) [!O_CLOEXEC]: Use fcntl with FD_CLOEXEC.
	(create_lock_file): Use write, not emacs_write.
	* image.c (slurp_file, png_load_body):
	* process.c (Fnetwork_interface_list, Fnetwork_interface_info)
	(server_accept_connection):
	Don't leak an fd on memory allocation failure.
	* image.c (slurp_file): Add a cheap heuristic for growing files.
	* xfaces.c (Fx_load_color_file): Block input around the fopen too,
	as that's what the other routines do.  Maybe input need not be
	blocked at all, but it's better to be consistent.
	Avoid undefined behavior when strlen is zero.

	* alloc.c (staticpro): Avoid buffer overrun on repeated calls.
	(NSTATICS): Now a constant; doesn't need to be a macro.

2013-07-19  Richard Stallman  <rms@gnu.org>

	* coding.c (decode_coding_utf_8): Add simple loop for fast
	processing of ASCII characters.

2013-07-19  Paul Eggert  <eggert@cs.ucla.edu>

	* conf_post.h (RE_TRANSLATE_P) [emacs]: Remove obsolete optimization.

2013-07-19  Eli Zaretskii  <eliz@gnu.org>

	* keyboard.c (kbd_buffer_get_event): Use Display_Info instead of
	unportable 'struct x_display_info'.
	(DISPLAY_LIST_INFO): Delete macro: not needed, since Display_Info
	is a portable type.

2013-07-19  Paul Eggert  <eggert@cs.ucla.edu>

	* sysdep.c [GNU_LINUX]: Fix fd and memory leaks and similar issues.
	(procfs_ttyname): Don't use uninitialized storage if emacs_fopen
	or fscanf fails.
	(system_process_attributes): Prefer plain char to unsigned char
	when either will do.  Clean up properly if interrupted or if
	memory allocations fail.  Don't assume sscanf succeeds.  Remove
	no-longer-needed workaround to stop GCC from whining.  Read
	command-line once, instead of multiple times.  Check read status a
	bit more carefully.

	Fix obscure porting bug with varargs functions.
	The code assumed that int is treated like ptrdiff_t in a vararg
	function, which is not a portable assumption.  There was a similar
	-- though these days less likely -- porting problem with various
	assumptions that pointers of different types all smell the same as
	far as vararg functions is conserved.  To make this problem less
	likely in the future, redo the API to use varargs functions.
	* alloc.c (make_save_value): Remove this vararg function.
	All uses changed to ...
	(make_save_int_int_int, make_save_obj_obj_obj_obj)
	(make_save_ptr_int, make_save_funcptr_ptr_obj, make_save_memory):
	New functions.
	(make_save_ptr): Rename from make_save_pointer, for consistency with
	the above.  Define only on platforms that need it.  All uses changed.

2013-07-18  Paul Eggert  <eggert@cs.ucla.edu>

	* keyboard.c: Try to fix typos in previous change.
	(DISPLAY_LIST_INFO): New macro.
	(kbd_buffer_get_event): Do not access members that are not present
	in X11.  Revert inadvertent change of "!=" to "=".

2013-07-18  Juanma Barranquero  <lekktu@gmail.com>

	* keyboard.c (kbd_buffer_get_event):
	* w32term.c (x_focus_changed): Port FOCUS_(IN|OUT)_EVENT changes to W32.
	Followup to 2013-07-16T11:41:06Z!jan.h.d@swipnet.se.

2013-07-18  Paul Eggert  <eggert@cs.ucla.edu>

	* filelock.c: Fix unlikely file descriptor leaks.
	(get_boot_time_1): Rework to avoid using emacs_open.
	This doesn't actually fix a leak, but is better anyway.
	(read_lock_data): Use read, not emacs_read.

	* doc.c: Fix minor memory and file descriptor leaks.
	* doc.c (get_doc_string): Fix memory leak when doc file absent.
	(get_doc_string, Fsnarf_documentation):
	Fix file descriptor leak on error.

	* term.c: Fix minor fdopen-related file descriptor leaks.
	* term.c (Fresume_tty) [!MSDOS]: Close fd if fdopen (fd) fails.
	(init_tty) [!DOS_NT]: Likewise.  Also close fd if isatty (fd) fails.

	* charset.c: Fix file descriptor leaks and errno issues.
	Include <errno.h>.
	(load_charset_map_from_file): Don't leak file descriptor on error.
	Use plain record_xmalloc since the allocation is larger than
	MAX_ALLOCA; that's simpler here.  Simplify test for exhaustion
	of entries.
	* eval.c (record_unwind_protect_nothing):
	* fileio.c (fclose_unwind):
	New functions.
	* lread.c (load_unwind): Remove.  All uses replaced by fclose_unwind.
	The replacement doesn't block input, but that no longer seems
	necessary.

2013-07-17  Paul Eggert  <eggert@cs.ucla.edu>

	* lread.c: Fix file descriptor leaks and errno issues.
	(Fload): Close some races that leaked fds or streams when 'load'
	was interrupted.
	(Fload, openp): Report error number of last nontrivial failure to open.
	ENOENT counts as trivial.
	* eval.c (do_nothing, clear_unwind_protect, set_unwind_protect_ptr):
	New functions.
	* fileio.c (close_file_unwind): No need to test whether FD is nonnegative,
	now that the function is always called with a nonnegative arg.
	* lisp.h (set_unwind_protect_ptr, set_unwind_protect_int): Remove.
	All uses replaced with ...
	(clear_unwind_protect, set_unwind_protect_ptr): New decls.

	A few more minor file errno-reporting bugs.
	* callproc.c (Fcall_process):
	* doc.c (Fsnarf_documentation):
	* fileio.c (Frename_file, Fadd_name_to_file, Fmake_symbolic_link):
	* process.c (set_socket_option):
	Don't let a constructor trash errno.
	* doc.c: Include <errno.h>.

2013-07-16  Juanma Barranquero  <lekktu@gmail.com>

	* w32fns.c (unwind_create_tip_frame): Fix declaration.

2013-07-16  Paul Eggert  <eggert@cs.ucla.edu>

	Fix w32 bug with call-process-region (Bug#14885).
	* callproc.c (Fcall_process_region): Pass nil, not "/dev/null",
	to Fcall_process when the input is empty.  This simplifies the
	code a bit.  It makes no difference on POSIXish platforms but
	apparently it fixes a bug on w32.

	Fix bug where insert-file-contents closes a file twice (Bug#14839).
	* fileio.c (close_file_unwind): Don't close if FD is negative;
	this can happen when unwinding a zapped file descriptor.
	(Finsert_file_contents): Unwind-protect the fd before the point marker,
	in case Emacs runs out of memory between the two unwind-protects.
	Don't trash errno when closing FD.
	Zap the FD in the specpdl when closing it, instead of deferring
	the removal of the unwind-protect; this fixes a bug where a child
	function unwinds the stack past us.

	New unwind-protect flavors to better type-check C callbacks.
	This also lessens the need to write wrappers for callbacks,
	and the need for make_save_pointer.
	* alloca.c (free_save_value):
	* atimer.c (run_all_atimers):
	Now extern.
	* alloc.c (safe_alloca_unwind):
	* atimer.c (unwind_stop_other_atimers):
	* keyboard.c (cancel_hourglass_unwind) [HAVE_WINDOW_SYSTEM]:
	* menu.c (cleanup_popup_menu) [HAVE_NS]:
	* minibuf.c (choose_minibuf_frame_1):
	* process.c (make_serial_process_unwind):
	* xdisp.h (pop_message_unwind):
	* xselect.c (queue_selection_requests_unwind):
	Remove no-longer-needed wrapper.  All uses replaced by the wrappee.
	* alloca.c (record_xmalloc):
	Prefer record_unwind_protect_ptr to record_unwind_protect with
	make_save_pointer.
	* alloca.c (Fgarbage_collect):
	Prefer record_unwind_protect_void to passing a dummy.
	* buffer.c (restore_buffer):
	* window.c (restore_window_configuration):
	* xfns.c, w32fns.c (do_unwind_create_frame)
	New wrapper.  All record-unwind uses of wrappee changed.
	* buffer.c (set_buffer_if_live):

	All uses changed.
	* editfns.c (Fformat): Update the saved pointer directly via
	set_unwind_protect_ptr rather than indirectly via make_save_pointer.
	* eval.c (specpdl_func): Remove.  All uses replaced by definiens.
	(unwind_body): New function.

	(record_unwind_protect_ptr, record_unwind_protect_int)
	(record_unwind_protect_void): New functions.
	(unbind_to): Support SPECPDL_UNWIND_PTR etc.

	* insdel.c (struct rvoe_arg): New type.
	(reset_var_on_error): Use it.
	* lisp.h (SPECPDL_UNWIND_PTR, SPECPDL_UNWIND_INT, SPECPDL_UNWIND_VOID):

	(union specbinding): New members unwind_ptr, unwind_int, unwind_void.
	(set_unwind_protect_ptr): New function.
	* xselect.c: Remove unnecessary forward decls, to simplify maintenance.

	Be simpler and more consistent about reporting I/O errors.
	* fileio.c (Fcopy_file, Finsert_file_contents, Fwrite_region):
	Say "Read error" and "Write error", rather than "I/O error", or
	"IO error reading", or "IO error writing", when a read or write
	error occurs.
	* process.c (Fmake_network_process, wait_reading_process_output)
	(send_process, Fprocess_send_eof, wait_reading_process_output):
	Capitalize diagnostics consistently.  Put "failed foo" at the
	start of the diagnostic, so that we don't capitalize the
	function name "foo".  Consistently say "failed" for such
	diagnostics.
	* sysdep.c, w32.c (serial_open): Now accepts Lisp string, not C string.
	All callers changed.  This is so it can use report_file_error.
	* sysdep.c (serial_open, serial_configure): Capitalize I/O
	diagnostics consistently as above.

	* fileio.c (report_file_errno): Fix errno reporting bug.
	If the file name is neither null nor a pair, package it up as a
	singleton list.  All callers changed, both to this function and to
	report_file_error.  This fixes a bug where the memory allocator
	invoked by list1 set errno so that the immediately following
	report_file_error reported the wrong errno value.

	Fix minor problems found by --enable-gcc-warnings.
	* frame.c (Fhandle_focus_in, Fhandle_focus_out): Return a value.
	* keyboard.c (kbd_buffer_get_event): Remove unused local.

2013-07-16  Jan Djärv  <jan.h.d@swipnet.se>

	* xterm.c (x_focus_changed): Always generate FOCUS_IN_EVENT.
	Set event->arg to Qt if switch-event shall be generated.
	Generate FOCUS_OUT_EVENT for FocusOut if this is the focused frame.

	* termhooks.h (enum event_kind): Add FOCUS_OUT_EVENT.

	* nsterm.m (windowDidResignKey): If this is the focused frame, generate
	FOCUS_OUT_EVENT.

	* keyboard.c (Qfocus_in, Qfocus_out): New static objects.
	(make_lispy_focus_in, make_lispy_focus_out): Declare and define.
	(kbd_buffer_get_event): For FOCUS_IN, make a focus_in event if no
	switch frame event is made.  Check ! NILP (event->arg) if X11 (moved
	from xterm.c).  Make focus_out event for FOCUS_OUT_EVENT if NS or X11
	and there is a focused frame.
	(head_table): Add focus-in and focus-out.
	(keys_of_keyboard): Add focus-in and focus-out to Vspecial_event_map,
	bind to handle-focus-in/out.

	* frame.c (Fhandle_focus_in, Fhandle_focus_out): New functions.
	(Fhandle_switch_frame): Call Fhandle_focus_in.
	(syms_of_frame): defsubr handle-focus-in/out.

2013-07-16  Paul Eggert  <eggert@cs.ucla.edu>

	Fix porting bug to older POSIXish platforms (Bug#14862).
	* sysdep.c (emacs_pipe): New function, that implements
	pipe2 (fd, O_CLOEXEC) even on hosts that lack O_CLOEXEC.
	This should port better to CentOS 5 and to Mac OS X 10.6.
	All calls to pipe2 changed.

	Prefer list1 (X) to Fcons (X, Qnil) when building lists.
	This makes the code easier to read and the executable a bit smaller.
	Do not replace all calls to Fcons that happen to create lists,
	just calls that are intended to create lists.  For example, when
	creating an alist that maps FOO to nil, use list1 (Fcons (FOO, Qnil))
	rather than list1 (list1 (FOO)) or Fcons (Fcons (FOO, Qnil), Qnil).
	Similarly for list2 through list5.

2013-07-15  Paul Eggert  <eggert@cs.ucla.edu>

	* callproc.c (Fcall_process_region): Fix minor race and tune.
	(create_temp_file): New function, with the temp-file-creation part
	of the old Fcall_process_region.  Use Fcopy_sequence to create the
	temp file name, rather than alloca + build_string, for simplicity.
	Don't bother to block input around the temp file creation;
	shouldn't be needed.  Simplify use of mktemp.  Use
	record_unwind_protect immediately after creating the temp file;
	this closes an unlikely race where the temp file was not removed.
	Use memcpy rather than an open-coded loop.
	(Fcall_process_region): Use the new function.  If the input is
	empty, redirect from /dev/null rather than from a newly created
	empty temp file; this avoids unnecessary file system traffic.

2013-07-14  Paul Eggert  <eggert@cs.ucla.edu>

	* filelock.c (create_lock_file) [!HAVE_MKOSTEMP && !HAVE_MKSTEMP]:
	Simplify by making this case like the other two.  This is a bit
	slower on obsolete hosts, but the extra complexity isn't worth it.

	* callproc.c (child_setup, relocate_fd) [!DOS_NT]:
	* process.c (create_process) [!DOS_NT]:
	Remove now-unnecessary calls to emacs_close.

2013-07-13  Eli Zaretskii  <eliz@gnu.org>

	* w32term.c (x_draw_hollow_cursor): Delete the brush object when
	returning early.  (Bug#14850)

	* coding.c (syms_of_coding): Set up inhibit-null-byte-detection
	and inhibit-iso-escape-detection attributes of 'undecided'.
	(Bug#14822)

2013-07-13  Paul Eggert  <eggert@cs.ucla.edu>

	* deps.mk (sysdep.o): Remove dependency on ../lib/ignore-value.h.
	Reported by Herbert J. Skuhra in
	<http://lists.gnu.org/archive/html/emacs-devel/2013-07/msg00455.html>.

	Don't lose top specpdl entry when memory is exhausted.
	* eval.c (grow_specpdl): Increment specpdl top by 1 and check for
	specpdl overflow here, to simplify callers; all callers changed.
	Always reserve an unused entry at the stack top; this avoids
	losing the top entry's information when memory is exhausted.

2013-07-12  Paul Eggert  <eggert@cs.ucla.edu>

	Clean up errno reporting and fix some errno-reporting bugs.
	* callproc.c (Fcall_process):
	* fileio.c (Fcopy_file, Finsert_file_contents, Fwrite_region):
	* process.c (create_process, Fmake_network_process):
	* unexaix.c (report_error):
	* unexcoff.c (report_error):
	Be more careful about reporting the errno of failed operations.
	The code previously reported the wrong errno sometimes.
	Also, prefer report_file_errno to setting errno + report_file_error.
	(Fcall_process): Look at openp return value rather than at path,
	as that's a bit faster and clearer when there's a numeric predicate.
	* fileio.c (report_file_errno): New function, with most of the
	old contents of report_file_error.
	(report_file_error): Use it.
	(Ffile_exists_p, Ffile_accessible_directory_p):
	Set errno to 0 when it is junk.
	* fileio.c (Faccess_file):
	* image.c (x_create_bitmap_from_file):
	Use faccessat rather than opening the file, to avoid the hassle of
	having a file descriptor open.
	* lisp.h (report_file_errno): New decl.
	* lread.c (Flocate_file_internal): File descriptor 0 is valid, too.

	Minor EBADF fixes.
	* process.c (create_process, wait_reading_process_output) [AIX]:
	Remove obsolete SIGHUP-related  code, as Emacs no longer disables
	SIGHUP, so EBADF is no longer acceptable here (it wouldn't work in
	a multithreaded environment anyway).
	* sysdep.c (emacs_close): It's not dangerous to invoke emacs_close (-1).

2013-07-12  Andreas Schwab  <schwab@linux-m68k.org>

	* image.c (x_find_image_file): Don't close a remote file handle.

2013-07-12  Paul Eggert  <eggert@cs.ucla.edu>

	Fix races with threads and file descriptors.
	* callproc.c (Fcall_process_region):
	* dired.c (open_directory):

	* unexaix.c, unexcoff.c, unexcw.c, unexelf.c (unexec):
	* unexhp9k800.c, unexmacosx.c (unexec):
	* callproc.c (Fcall_process_region):
	Use emacs_close, not close.
	* sysdep.c (POSIX_CLOSE_RESTART, posix_close) [!POSIX_CLOSE_RESTART]:
	New macro and function, which emulates the POSIX_CLOSE_RESTART macro
	and posix_close function on current platforms (which all lack them).
	(emacs_close): Use it.  This should fix the races on GNU/Linux and
	on AIX and on future platforms that support POSIX_CLOSE_RESTART,
	and it should avoid closing random victim file descriptors on
	other platforms.

2013-07-11  Paul Eggert  <eggert@cs.ucla.edu>

	* inotify.c (uninitialized): Remove.  All uses replaced by -1.
	(Finotify_add_watch): Simplify, since -1 means uninitialized now.
	Touch up doc a bit.

	* eval.c (backtrace_function, backtrace_args): Now EXTERNALLY_VISIBLE.
	This is for .gdbinit xbacktrace.

	* sysdep.c, term.c, termcap.c, terminal.c: Integer-related minor fixes.
	* sysdep.c (emacs_get_tty): Return void, since nobody uses the value.
	(emacs_set_tty): Now static.
	* sysdep.c (emacs_set_tty, tabs_safe_p, emacs_close):
	* term.c (tty_capable_p, tty_default_color_capabilities)
	(get_tty_terminal, term_mouse_movement)
	(handle_one_term_event, init_tty, maybe_fatal):
	* termcap.c (tgetst1, struct termcap_buffer, valid_filename_p)
	(tgetent, scan_file, name_match, compare_contin):
	* terminal.c (get_terminal):
	Use bool for boolean.
	* sysdep.c (init_system_name): Don't overflow stack on huge hostname.
	Prefer char to unsigned char if either will do.
	* term.c (OUTPUT, turn_on_face): Omit unnecessary casts to int.
	(tty_write_glyphs): Prefer int to unsigned.
	(produce_glyphless_glyph): Remove 2nd (unused) int arg.
	All callers changed.
	* termcap.c (tprint, main) [TEST]: Remove non-working test.

2013-07-10  Paul Eggert  <eggert@cs.ucla.edu>

	Port to C89.
	* bytecode.c (BYTE_CODE_THREADED): Do not define if __STRICT_ANSI__.
	(B__dummy__): New dummy symbol, to pacify C89.
	* dbusbind.c (XD_DEBUG_MESSAGE): Omit debugging on C89 hosts, since
	they can't grok varargs macros.
	* dispnew.c (add_window_display_history)
	(add_frame_display_history):
	* print.c (print_object):
	* xdisp.c (debug_method_add):
	Use %p printf format only for void pointers.
	* emacs.c (usage_message): New constant, replacing ...
	(USAGE1, USAGE2, USAGE3): Remove; they were too long for C89.
	(main): Adjust to usage reorg.
	* fns.c (syms_of_fns):
	* profiler.c (syms_of_profiler):
	Don't use non-constant struct initializers.
	* gnutls.h (gnutls_initstage_t):
	* lisp.h (enum Lisp_Fwd_Type):
	* lread.c (lisp_file_lexically_bound_p):
	* xsettings.c (anonymous enum):
	Remove trailing comma.
	* xsettings.c (apply_xft_settings): Use %f, not %lf; %lf is a C99ism.
	* lisp.h (ENUM_BF): Use unsigned if pedantic.
	(DEFUN_FUNCTION_INIT): New macro, that falls back on a cast if pre-C99.
	(DEFUN): Use it.
	* regex.c (const_re_char): New type, to pacify strict C89.
	All uses of 'const re_char' replaced to use it.
	* regex.h (_Restrict_): Rename from __restrict, to avoid clash
	with glibc when strict C89.  This change is imported from gnulib.
	All uses changed.
	(_Restrict_arr_): Rename from __restrict_arr, similarly.
	* sysdep.c (time_from_jiffies) [!HAVE_LONG_LONG_INT]:
	Omit GNU_LINUX implementation, since it requires long long.
	* xterm.c (x_draw_underwave):
	Do not assume the traditional order of struct's members.
	(x_term_init): Rewrite to avoid the need for non-constant structure
	initializers.

	Syntax cleanup, mostly replacing macros with functions.
	This removes the need for the syntax_temp hack.
	* search.c: Include syntax.h after buffer.h, since syntax.h uses BVAR.
	* syntax.c (SYNTAX_INLINE): New macro.
	(SYNTAX_FLAGS_COMSTART_FIRST, SYNTAX_FLAGS_COMSTART_SECOND)
	(SYNTAX_FLAGS_COMEND_FIRST, SYNTAX_FLAGS_COMEND_SECOND)
	(SYNTAX_FLAGS_PREFIX, SYNTAX_FLAGS_COMMENT_STYLEB)
	(SYNTAX_FLAGS_COMMENT_STYLEC, SYNTAX_FLAGS_COMMENT_STYLEC2)
	(SYNTAX_FLAGS_COMMENT_NESTED, SYNTAX_FLAGS_COMMENT_STYLE)
	(SYNTAX_COMEND_FIRST): Now functions, not macros.
	(ST_COMMENT_STYLE, ST_STRING_STYLE, INTERVALS_AT_ONCE):
	Now constants, not macros.
	(syntax_temp) [!__GNUC__]: Remove.
	(SYNTAX_PREFIX): Remove; all uses replaced by syntax_prefix_flag_p.
	(syntax_prefix_flag_p): Move implementation of SYNTAX_PREFIX here.
	(SET_RAW_SYNTAX_ENTRY, SET_RAW_SYNTAX_ENTRY_RANGE, SYNTAX_MATCH)
	(SETUP_SYNTAX_TABLE, SETUP_SYNTAX_TABLE_FOR_OBJECT):
	Move here from syntax.h; now functions, not macros.  Except for the
	last function, these are static since only syntax.c uses them.
	(syntax_multibyte): Rename from SYNTAX_WITH_MULTIBYTE_CHECK.
	All uses changed.  Now a function, not a macro; use this fact
	to simplify the code.
	(scan_lists, scan_sexps_forward): Remove workarounds for ancient
	compiler bugs; no longer relevant.
	* syntax.h: Use INLINE_HEADER_BEGIN, INLINE_HEADER_END.
	(SYNTAX_INLINE): New macro.
	(struct gl_state_s, gl_state): Move earlier, so that it's in scope
	for the new functions.  Use bool for boolean member.
	(SYNTAX_ENTRY, SYNTAX, SYNTAX_WITH_FLAGS, SYNTAX_MATCH)
	(SYNTAX_TABLE_BYTE_TO_CHAR, UPDATE_SYNTAX_TABLE_FORWARD)
	(UPDATE_SYNTAX_TABLE_BACKWARD, UPDATE_SYNTAX_TABLE)
	(SETUP_BUFFER_SYNTAX_TABLE):
	Now extern inline functions, not macros.
	(CURRENT_SYNTAX_TABLE, SYNTAX_ENTRY_INT):
	Remove; all uses replaced by implementation.
	(syntax_temp) [!__GNUC__]: Remove decl.
	(SETUP_SYNTAX_TABLE_FOR_OBJECT): New decl.

2013-07-10  Jan Djärv  <jan.h.d@swipnet.se>

	* emacs.c (main): Fix syntax error.

2013-07-10  Paul Eggert  <eggert@cs.ucla.edu>

	Timestamp fixes for undo (Bug#14824).
	* atimer.c (schedule_atimer):
	* fileio.c (Ffile_newer_than_file_p):
	Minor cleanup: use EMACS_TIME_LT so that we can remove EMACS_TIME_GT.
	* buffer.c (buffer-undo-list): Document (t . 0) and (t . -1).
	* fileio.c (Fclear_visited_file_modtime): Move to lisp/files.el.
	(syms_of_fileio): Remove Sclear_visited_file_name.
	(Fvisited_file_modtime): Return -1, not (-1 ...), when the visited
	file doesn't exist; this avoids an ambiguity with negative timestamps.
	(Fset_visited_file_modtime): Accept -1 and 0 as time-list arg.
	* systime.h (make_emacs_time, invalid_emacs_time):
	Don't assume struct timespec layout; POSIX doesn't guarantee it.
	(EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE): Remove.
	* undo.c (record_first_change): Push (visited-file-modtime) onto
	undo list rather than reimplementing it by hand, incorrectly.

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

2013-07-09  Paul Eggert  <eggert@cs.ucla.edu>

	Handle errno and exit status a bit more carefully.
	* callproc.c (child_setup) [!DOS_NT]: Don't try to stuff an error
	number into an exit status.  Instead, use EXIT_CANCELED.
	(child_setup) [!MSDOS]: Avoid possible deadlock with vfork.
	* callproc.c (relocate_fd):
	* emacs.c (close_output_streams, main):
	* process.c (create_process):
	* sysdep.c (sys_subshell) [!DOS_NT || !WINDOWSNT]:
	Use emacs_perror for simplicity.
	* callproc.c (relocate_fd, main):
	* sysdep.c (sys_subshell):
	Exit with EXIT_CANCELED etc., not 1, when exec setup fails.
	(shut_down_emacs): Use emacs_write, not write.
	* emacs.c, sysdep.c: Don't include <ignore-value.h>.
	* fileio.c (Fcopy_file, e_write):

2013-07-07  Paul Eggert  <eggert@cs.ucla.edu>

	Make file descriptors close-on-exec when possible (Bug#14803).
	This simplifies Emacs a bit, since it no longer needs to worry
	about closing file descriptors by hand in some cases.
	It also fixes some unlikely races.  Not all such races, as
	libraries often open files internally without setting
	close-on-exec, but it's an improvement.
	* alloc.c (valid_pointer_p) [!WINDOWSNT]:
	* callproc.c (Fcall_process) [!MSDOS]:
	* emacs.c (main) [!DOS_NT]:
	* nsterm.m (ns_term_init):
	* process.c (create_process):
	Use 'pipe2' with O_CLOEXEC instead of 'pipe'.
	* emacs.c (Fcall_process_region) [HAVE_MKOSTEMP]:
	* filelock.c (create_lock_file) [HAVE_MKOSTEMP]:
	Prefer mkostemp with O_CLOEXEC to mkstemp.
	* callproc.c (relocate_fd) [!WINDOWSNT]:
	* emacs.c (main): Use F_DUPFD_CLOEXEC, not plain F_DUPFD.
	No need to use fcntl (..., F_SETFD, FD_CLOEXEC), since we're
	now using pipe2.
	* filelock.c (create_lock_file) [! HAVE_MKOSTEMP]:
	Make the resulting file descriptor close-on-exec.
	* lisp.h, lread.c, process.c (close_load_descs, close_process_descs):
	* lread.c (load_descriptor_list, load_descriptor_unwind):
	Remove; no longer needed.  All uses removed.
	* process.c (SOCK_CLOEXEC): Define to 0 if not supplied by system.
	(close_on_exec, accept4, process_socket) [!SOCK_CLOEXEC]:
	New functions.
	(socket) [!SOCK_CLOEXEC]: Supply a substitute.
	(Fmake_network_process, Fnetwork_interface_list):
	(Fnetwork_interface_info, server_accept_connection):
	Make newly-created socket close-on-exec.
	* sysdep.c (emacs_open, emacs_fopen):
	Make new-created descriptor close-on-exec.
	* w32.c (fcntl): Support F_DUPFD_CLOEXEC well enough for Emacs.
	* w32.c, w32.h (pipe2): Rename from 'pipe', with new flags arg.

2013-07-07  Jan Djärv  <jan.h.d@swipnet.se>

	* nsterm.m (sendEvent:): Handle NSAPP_DATA2_RUNFILEDIALOG.

	* nsterm.h (NSSavePanel): Update comment.

	(ns_run_file_dialog): Declare.

	* nsfns.m: Remove panelOK.
	(ns_fd_data): New.
	(ns_run_file_dialog): New function.
	(Fns_read_file_name): Fill in ns_fd_data, post an event and start the
	event loop, so file dialog is popped up by ns_run_file_dialog, called
	by sendEvent (Bug#14578).
	(EmacsSavePanel, EmacsOpenPanel): Remove ok and cancel methods.

2013-07-06  Eli Zaretskii  <eliz@gnu.org>

	* xdisp.c (default_line_pixel_height): New function.
	(pos_visible_p, move_it_vertically_backward, try_scrolling)

2013-07-05  Paul Eggert  <eggert@cs.ucla.edu>

	Use emacs_open more consistently when opening files.
	This handles EINTR more consistently now, and makes it easier
	to introduce other uniform changes to file descriptor handling.
	* src/systdio.h: New file.
	* src/buffer.c (mmap_init):
	* cygw32.c (chdir_to_default_directory):

	Remove duplicate #include directives.
	* alloc.c [GC_MARK_STACK == GC_USE_GCPROS_CHECK_ZOMBIES]:
	* xfaces.c:
	Don't include stdio.h twice.
	* buffer.c [USE_MMAP_FOR_BUFFERS]:

	Do not clear _malloc_thread_enabled_p, undoing the previous change,
	which did not work (see <http://bugs.gnu.org/14569#307>).
	(main): Do not invoke malloc_enable_thread if (! CANNOT_DUMP
	&& (!noninteractive || initialized)).  This attempts to thread
	the needle between the Scylla of FreeBSD and the Charybdis of Cygwin.

2013-07-04  Juanma Barranquero  <lekktu@gmail.com>

	* image.c (x_to_xcolors) [HAVE_NTGUI]: Remove unused var `hdc'.

2013-07-02  Paul Eggert  <eggert@cs.ucla.edu>

	* sysdep.c (sys_siglist) [HAVE_DECL___SYS_SIGLIST]:
	Define to __sys_siglist.

2013-07-02  Eli Zaretskii  <eliz@gnu.org>

	* xdisp.c (IT_OVERFLOW_NEWLINE_INTO_FRINGE): Don't disallow
	word-wrap, so that overflow-newline-into-fringe would work in
	visual-line-mode.  (Bug#2749)
	(move_it_in_display_line_to): When the last scanned display
	element fits exactly on the display line, and
	overflow-newline-into-fringe is non-nil, but wrap_it is valid,
	don't return MOVE_NEWLINE_OR_CR, but instead back up to the last
	wrap point and return MOVE_LINE_CONTINUED.  Fixes problems with
	finding buffer position that corresponds to pixel coordinates,
	e.g. in buffer_posn_from_coords.

2013-07-02  Jan Djärv  <jan.h.d@swipnet.se>

	* process.c (handle_child_signal): Call catch_child_signal if
	NS_IMPL_GNUSTEP.

2013-07-02  Paul Eggert  <eggert@cs.ucla.edu>

	(voidfuncptr): New typedef.
	(struct Lisp_Save_Value): New member data[0].funcpointer.
	(XSAVE_FUNCPOINTER): New function.

	Simplify buildobj processing.
	* Makefile.in (buildobj.h): Make it a sequence of strings each
	followed by comma, rather than a single string.  Put it into a
	.tmp file in case there's an error while generating it.
	(gl-stamp): Use .tmp for temp files.
	(mostlyclean): Clean .tmp files.
	* doc.c (buildobj): Move to just the routine that needs it.
	It's now an array of strings, so processing is simpler.

2013-07-01  Paul Eggert  <eggert@cs.ucla.edu>

	Fix bug re noninteractive multithreaded memory allocation (Bug#14569).
	* emacs.c (malloc_enable_thread): Hoist extern decl to top level.
	(main) [HAVE_PTHREAD && !SYSTEM_MALLOC && !DOUG_LEA_MALLOC]:
	Invoke malloc_enable_thread even when not interactive.
	Problem reported by Ken Brown in <http://bugs.gnu.org/14569#275>.
	* process.c (init_process_emacs) [CYGWIN]: Tickle glib even

2013-07-01  Juanma Barranquero  <lekktu@gmail.com>

	* emacs.c (Fkill_emacs): Expand Vauto_save_list_file_name before
	unlinking it (bug#14691).

2013-06-30  Michal Nazarewicz  <mina86@mina86.com>

	* buffer.c (FKill_buffer): Run `kill-buffer-query-functions'
	before checking whether buffer is modified.  This lets
	`kill-buffer-query-functions' cancel killing of the buffer or save
	its content before `kill-buffer' asks user the "Buffer %s
	modified; kill anyway?" question.

2013-06-30  Jan Djärv  <jan.h.d@swipnet.se>

	* nsfns.m (handlePanelKeys): Don't process Command+Function keys.
	Let the super performKeyEquivalent deal with them (Bug#14747).

2013-06-30  Paul Eggert  <eggert@cs.ucla.edu>

	* widget.c (resize_cb): Remove unused local.

2013-06-30  Eli Zaretskii  <eliz@gnu.org>

	* intervals.c (get_local_map): Instead of aborting, clip POSITION
	to the valid range of values.  (Bug#14753)

	* xdisp.c (Fmove_point_visually): Invalidate the cursor position
	when moving point by using the current glyph matrix.  This avoids
	the need to force redisplay when this function is called in a
	loop.

2013-06-29  Paul Eggert  <eggert@cs.ucla.edu>

	Fix minor problems found by static checking.
	* coding.c (encode_inhibit_flag, inhibit_flag): New functions.
	Redo the latter's body to sidestep GCC parenthesization warnings.
	(setup_coding_system, detect_coding, detect_coding_system): Use them.
	* coding.c (detect_coding, detect_coding_system):
	* coding.h (struct undecided_spec):
	Use bool for boolean.

	* xdisp.c (Fmove_point_visually): Remove unused local.

2013-06-29  Eli Zaretskii  <eliz@gnu.org>

	* xdisp.c (Fmove_point_visually): New function.

	and `mask_img'.

	* image.c (Destroy_Image): Remove.
	(x_clear_image_1): New arg `flags' instead of 3 bools `pixmap_p',
	`mask_p', and `colors_p'.  All uses changed.

	(xpm_load_image, x_from_xcolors, x_build_heuristic_mask, pbm_load)
	(png_load_body, jpeg_load_body, tiff_load, gif_load)

	x_create_x_image_and_pixmap, and x_put_x_image followed by
	x_destroy_x_image, respectively.
	(xpm_load) [HAVE_XPM && !HAVE_NTGUI]: Use XpmReadFileToImage and

2013-06-27  Paul Eggert  <eggert@cs.ucla.edu>

	Do not tickle glib SIGCHLD handling if Cygwin (Bug#14569).
	This mostly consists of undoing recent changes.
	* callproc.c (Fcall_process):
	* process.c (create_process):
	Do not worry about catching SIGCHLD here, undoing previous change.
	* nsterm.m (ns_term_init): Re-catch SIGCHLD, undoing previous change.
	* process.c, process.h (catch_child_signal):
	No longer extern if !NS_IMPL_GNUSTEP, undoing 06-22 change.
	* process.c (catch_child_handler): Don't worry about being called
	lazily and do not assume caller has blocked SIGCHLD, undoing
	previous change.  Move first-time stuff back to
	init_process_emacs, undoing 06-22 change.  If CYGWIN, do not
	tickle glib, as that causes Cygwin bootstrap to fail.  Do not
	set lib_child_handler if it's already initialized, which may
	help avoid problems on GNUStep.

2013-06-23  Paul Eggert  <eggert@cs.ucla.edu>

	A more-conservative workaround for Cygwin SIGCHLD issues (Bug#14569).
	* callproc.c (Fcall_process):
	* process.c (create_process):
	Make sure SIGCHLD is caught before we fork,
	since Emacs startup no arranges to catch SIGCHLD.
	* process.c (lib_child_handler): Initialize to null, not to
	dummy_handler.
	(catch_child_signal): Allow self to be called lazily.
	Do nothing if it's already been called.
	Assume caller has blocked SIGCHLD (all callers do now).
	* emacs.c (main): Do not catch SIGCHLD here; defer it until
	just before it's really needed.
	* nsterm.m (ns_term_init): No need to re-catch SIGCHLD here,
	since it hasn't been caught yet.

2013-06-23  Lars Magne Ingebrigtsen  <larsi@gnus.org>

	* image.c (compute_image_size): New function to implement
	:max-width and :max-height.
	(imagemagick_load_image): Use it.

2013-06-23  Paul Eggert  <eggert@cs.ucla.edu>

	Try to avoid malloc SEGVs on Cygwin (Bug#14569).
	* callproc.c, process.h (block_child_signal, unblock_child_signal):
	Now extern.
	* emacs.c (main): Catch SIGCHLD just before initializing gfilenotify.
	* process.c (catch_child_signal): Block SIGCHLD while futzing with
	the SIGCHLD handler, since the code is not atomic and (due to glib)
	signals may be arriving now.
	* sysdep.c (init_signals): Do not catch child signals here;
	'main' now does that later, at a safer time.

2013-06-22  Paul Eggert  <eggert@cs.ucla.edu>

	Clean up SIGCHLD handling a bit (Bug#14569).
	* process.c, process.h (catch_child_signal):
	Now always extern, even if !NS_IMPL_GNUSTEP.
	* process.c (catch_child_signal): Move glib tickler here from
	init_process_emacs, so that it's done earlier in Emacs
	initialization.  Also move the noninteractive && !initialized
	check here from init_process_emacs.  This is all a bit cleaner for
	GNUish platforms, and I hope it works around the Cygwin bug.
	* sysdep.c (init_signals): Invoke catch_child_signal here, so
	that glib signal handling is tickled before glib creates threads.

	* process.c (wait_reading_process_output): Avoid int overflow
	when reading more than 2 GiB total from a process.

2013-06-21  Paul Eggert  <eggert@cs.ucla.edu>

	* process.c (create_process): Handle a couple more cases,
	i.e., work even if new_argv and wait_child_setup[i] are cached.
	Use Fcall_process's style for volatile vars.

2013-06-21  Andreas Schwab  <schwab@linux-m68k.org>

	* process.c (create_process): Mark PROCESS volatile.

2013-06-21  Paul Eggert  <eggert@cs.ucla.edu>

	Use C99-style flexible array members if available.
	This avoids some subtle aliasing issues, which typically
	aren't a problem with GCC but may be a problem elsewhere.
	* alloc.c (sdata): New typedef, replacing the old struct sdata.
	It is a struct if GC_CHECK_STRING_BYTES, a union otherwise.
	In either case, it uses a flexible array member rather than
	the old struct hack.  All uses changed.
	(SDATA_NBYTES, sweep_strings) [!GC_CHECK_STRING_BYTES]:
	Adjust to sdata reorganization.
	* alloc.c (VBLOCK_BYTES_MIN, allocate_vectorlike, Fgarbage_collect):
	Use offsetof (struct, flex_array_member), not sizeof (struct), as
	that ports better to pre-C99 non-GCC.
	* chartab.c (Fmake_char_table, make_sub_char_table, copy_char_table):
	Use CHAR_TABLE_STANDARD_SLOTS rather than its definition,
	as the latter has changed.
	* conf_post.h (FLEXIBLE_ARRAY_MEMBER): Move here from w32.c,
	and port better to pre-C99 GCC.
	* image.c (struct xpm_cached_color):
	* lisp.h (struct Lisp_Vector, struct Lisp_Bool_Vector)
	(struct Lisp_Char_Table, struct Lisp_Sub_Char_Table):
	Use FLEXIBLE_ARRAY_MEMBER.
	* lisp.h (string_bytes) [GC_CHECK_STRING_BYTES]:
	Move decl to top level so it gets checked against implementation.
	(CHAR_TABLE_STANDARD_SLOTS): Adjust to struct Lisp_Char_Table change.
	* w32.c (FLEXIBLE_ARRAY_MEMBER): Move to conf_post.h.

2013-06-20  Paul Eggert  <eggert@cs.ucla.edu>

	* syntax.c: Integer cleanups.
	(SYNTAX_FLAGS_COMMENT_STYLEC): Return a boolean, not 0-or-2.
	All uses that need 0-or-2 changed to:
	(SYNTAX_FLAGS_COMMENT_STYLEC2): New macro, with the same semantics
	as the old SYNTAX_FLAGS_COMMENT_STYLEC.
	(struct lisp_parse_state, syntax_prefix_flag_p, update_syntax_table)
	(char_quoted, prev_char_comend_first, back_comment)
	(Finternal_describe_syntax_value, skip_chars, skip_syntaxes)
	(in_classes, forw_comment, scan_lists, scan_sexps_forward):
	Use bool for boolean.
	(update_syntax_table, skip_chars, skip_syntaxes):
	Prefer int to unsigned when either will do.
	(back_comment): Return boolean success flag, like forw_comment,
	instead of positive-or-minus-1 (which might have overflowed int anyway).
	Don't stuff ptrdiff_t into int.
	(syntax_spec_code, syntax_code_spec): Now const.
	(Fmatching_paren, scan_lists, scan_sexps_forward):
	Use enum syntaxcode for syntax code.
	(Fmatching_paren): Check that arg is a character, not just an integer.
	(Fstring_to_syntax): Don't assume 0377 fits in enum syntaxcode.
	(Finternal_describe_syntax_value): Omit no-longer-needed
	comparison to 0.
	(skip_chars): Use char, not unsigned char, when the distinction
	doesn't matter.
	(forw_comment, scan_lists): Prefer A |= B to A = A || B when B's cheap.
	* bytecode.c (exec_byte_code):
	* syntax.c (syntax_spec_code, Fchar_syntax)
	(Finternal_describe_syntax_value, skip_chars, skip_syntaxes)
	(init_syntax_once):
	* syntax.h (SYNTAX_WITH_FLAGS):
	Omit unnecessary casts.

2013-06-20  Eli Zaretskii  <eliz@gnu.org>

	* w32fns.c (w32_wnd_proc): Don't compute the header line and mode
	line dimensions here, to avoid race conditions with the main
	thread.  (Bug#14062, bug#14630, bug#14669)

	* w32term.c (w32_draw_window_cursor): Compute the header line and
	mode line dimensions here.
	<w32_system_caret_window, w32_system_caret_hdr_height>:
	<w32_system_caret_mode_height>: New variables.

	* w32term.h: Declare them.

2013-06-20  Paul Eggert  <eggert@cs.ucla.edu>

	* alloc.c (die): Move "assertion failed" string here ...
	* lisp.h (eassert): ... from here.  Also, suppress evaluation of
	COND when SUPPRESS_CHECKING.  This shrinks the executable text
	size by 0.8% to 2.2% when configured with --enable-checking,
	depending on optimization flags (GCC 4.8.1 x86-64).

	* floatfns.c (Flog10): Move to Lisp (marked obsolete there).

2013-06-20  Rüdiger Sonderfeld  <ruediger@c-plusplus.de>

	* floatfns.c (Flog) [HAVE_LOG2]: Use log2 if available and if the
	base is 2; this is more accurate.

2013-06-19  Juanma Barranquero  <lekktu@gmail.com>

	* sound.c (string_default): Move to !WINDOWSNT section.
	(Fplay_sound_internal) [WINDOWSNT]: Remove i_result to avoid warning.

2013-06-19  Paul Eggert  <eggert@cs.ucla.edu>

	* sound.c: Integer cleanups.
	Remove unnecessary forward decls.
	(struct sound_device): The 'file' member is now a Lisp_Object, not
	a char *, so that we needn't invoke alloca on a huge size.
	(Fplay_sound_internal): Adjust to this.
	(string_default): New function.
	(vox_open, vox_init, alsa_open, alsa_configure, alsa_init):
	Use it to adjust to the struct sound_device change.
	(parse_sound, wav_init, au_init, alsa_init): Use bool for booleans.
	(be2hs) [0]: Remove.

	* syntax.c (skip_chars): Don't use uninitialized storage
	when searching a multibyte buffer for characters that are not in a
	unibyte string that contains non-ASCII characters.

2013-06-18  Jan Djärv  <jan.h.d@swipnet.se>

	* process.c: Include xgselect.h if HAVE_GLIB.  Include glib.h
	if HAVE_GLIB && ! WINDOWSNT (Bug#14654).

2013-06-18  Paul Eggert  <eggert@cs.ucla.edu>

	* conf_post.h: Add comments for INLINE, EXTERN_INLINE, etc.

2013-06-18  Kenichi Handa  <handa@gnu.org>

	* font.c (Ffont_spec): Signal an error for an invalid font name
	(Bug#14648).

2013-06-18  Paul Eggert  <eggert@cs.ucla.edu>

	Porting fixes for merged specpdl and backtrace stacks (Bug#14643).
	In particular this ports to 32-bit sparc Sun cc.
	* eval.c (init_eval_once, grow_specpdl): Allocate a specbinding
	array with a dummy element at specpdl[-1], so that its address can
	be taken portably.
	(unbind_to): Do not copy the binding; not needed, now that we
	copy old_value in the one place where the copy is needed.
	* fileio.c (Fwrite_region): Use ptrdiff_t, not int, for specpdl count.
	* lisp.h (BITS_PER_PTRDIFF_T): Remove; no longer needed.
	(union specbinding): Rename from struct specbinding.  Redo layout
	to avoid the need for 'ptrdiff_t nargs : BITS_PER_PTRDIFF_T - 1;',
	which is not portable.  With Sun C 5.12 32-bit sparc, the
	declaration causes nargs to be an unsigned bitfield, a behavior
	that the C standard allows; but Emacs wants nargs to be signed.
	The overall type is now a union of structures rather than a
	structure of union of structures, and the 'kind' member is now a
	bitfield, so that the overall type doesn't grow.  All uses changed.
	* process.c (Fmake_serial_process): Remove unnecessary initialization.

2013-06-17  Paul Eggert  <eggert@cs.ucla.edu>

	* frame.c (x_report_frame_params): Cast parent_desc to uintptr_t.
	Needed if HAVE_NTGUI.  Reported by Juanma Barranquero.

	* nsfont.m (ns_registry_to_script): Parenthesize while expression.

2013-06-17  Eli Zaretskii  <eliz@gnu.org>

	* w32fns.c (w32_wnd_proc): Don't call WINDOW_HEADER_LINE_HEIGHT
	unless we know that the window w's frame is a frame object.
	Another attempt at solving bug#14062 and bug#14630.

2013-06-17  Lars Magne Ingebrigtsen  <larsi@gnus.org>

	* textprop.c (property_set_type): New enum.
	(add_properties): Allow appending/prepending text properties.
	(add_text_properties_1): Factored out of Fadd_text_properties.
	(Fadd_text_properties): Move all the code into
	add_text_properties_1.
	(Fadd_face_text_property): New function that calls
	add_text_properties_1.

2013-06-17  Paul Eggert  <eggert@cs.ucla.edu>

	Move functions from lisp.h to individual modules when possible.
	From a suggestion by Andreas Schwab in <http://bugs.gnu.org/11935#68>.
	* alloc.c (XFLOAT_INIT, set_symbol_name):
	* buffer.c (CHECK_OVERLAY):
	* chartab.c (CHECK_CHAR_TABLE, set_char_table_ascii)
	(set_char_table_parent):
	* coding.c (CHECK_NATNUM_CAR, CHECK_NATNUM_CDR):
	* data.c (BOOLFWDP, INTFWDP, KBOARD_OBJFWDP, OBJFWDP, XBOOLFWD)
	(XKBOARD_OBJFWD, XINTFWD, XOBJFWD, CHECK_SUBR, set_blv_found)
	(blv_value, set_blv_value, set_blv_where, set_blv_defcell)
	(set_blv_valcell):
	* emacs.c (setlocale) [!HAVE_SETLOCALE]:
	* eval.c (specpdl_symbol, specpdl_old_value, specpdl_where)
	(specpdl_arg, specpdl_func, backtrace_function, backtrace_nargs)
	(backtrace_args, backtrace_debug_on_exit):
	* floatfns.c (CHECK_FLOAT):
	* fns.c (CHECK_HASH_TABLE, CHECK_LIST_END)
	(set_hash_key_and_value, set_hash_next, set_hash_next_slot)
	(set_hash_hash, set_hash_hash_slot, set_hash_index)
	(set_hash_index_slot):
	* keymap.c (CHECK_VECTOR_OR_CHAR_TABLE):
	* marker.c (CHECK_MARKER):
	* textprop.c (CHECK_STRING_OR_BUFFER):
	* window.c (CHECK_WINDOW_CONFIGURATION):
	Move here from lisp.h, and make these functions static rather than
	extern inline.
	* buffer.c (Qoverlayp):
	* data.c (Qsubrp):
	* fns.c (Qhash_table_p):
	* window.c (Qwindow_configuration_p):
	Now static.
	* lisp.h: Remove the abovementioned defns and decls.

	Use functions, not macros, for XINT etc (Bug#11935).
	In lisp.h, prefer functions to function-like macros, and
	constants to object-like macros, when either will do.  This:
	 . simplifies use, as there's no more need to worry about
	   arguments' side effects being evaluated multiple times.
	 . makes the code easier to debug on some platforms.
	However, when using gcc -O0, keep using function-like macros
	for a few critical operations, for performance reasons.
	This sort of thing isn't needed with gcc -Og, but -Og
	is a GCC 4.8 feature and isn't widely-enough available yet.
	* alloc.c (gdb_make_enums_visible) [USE_LSB_TAG]:
	Remove enum lsb_bits; no longer needed.
	(allocate_misc, free_misc): Don't use XMISCTYPE as an lvalue.
	* buffer.c (Qoverlap):
	* data.c (Qsubrp):
	* fns.c (Qhash_table_p):
	Now extern, so lisp.h can use these symbols.
	* dispextern.h: Include character.h, for MAX_CHAR etc.
	(GLYPH, GLYPH_CHAR, GLYPH_FACE, SET_GLYPH_CHAR, SET_GLYPH_FACE)
	(SET_GLYPH, GLYPH_CODE_CHAR, GLYPH_CODE_FACE)
	(SET_GLYPH_FROM_GLYPH_CODE, GLYPH_MODE_LINE_FACE, GLYPH_CHAR_VALID_P)
	(GLYPH_CODE_P): Move here from lisp.h.
	(GLYPH_CHAR, GLYPH_FACE, GLYPH_CODE_CHAR, GLYPH_CODE_FACE)
	(GLYPH_CHAR_VALID_P, GLYPH_CODE_P): Now functions, not macros.
	(GLYPH_MODE_LINE_FACE): Now enums, not macros.
	* eval.c (Fautoload): Cast XUNTAG output to intptr_t, since
	XUNTAG now returns void *.
	* lisp.h (lisp_h_XLI, lisp_h_XIL, lisp_h_CHECK_LIST_CONS)
	(lisp_h_CHECK_NUMBER CHECK_SYMBOL, lisp_h_CHECK_TYPE)
	(lisp_h_CONSP, lisp_h_EQ, lisp_h_FLOATP, lisp_h_INTEGERP)
	(lisp_h_MARKERP, lisp_h_MISCP, lisp_h_NILP)

	(lisp_h_XCAR, lisp_h_XCDR, lisp_h_XCONS, lisp_h_XHASH)
	(lisp_h_XPNTR, lisp_h_XSYMBOL):
	New macros, renamed from their sans-lisp_h_ counterparts.
	(XLI, XIL, CHECK_LIST_CONS, CHECK_NUMBER CHECK_SYMBOL)
	(CHECK_TYPE, CONSP, EQ, FLOATP, INTEGERP, MARKERP)
	(MISCP, NILP, SET_SYMBOL_VAL, SYMBOL_CONSTANT_P, SYMBOL_VAL, SYMBOLP)
	(VECTORLIKEP, XCAR, XCDR, XCONS, XHASH, XPNTR, XSYMBOL):
	If compiling via GCC without optimization, define these as macros
	in addition to inline functions.
	To disable this, compile with -DINLINING=0.
	(LISP_MACRO_DEFUN, LISP_MACRO_DEFUN_VOID): New macros.
	(check_cons_list) [!GC_CHECK_CONS_LIST]: Likewise.
	(make_number, XFASTINT, XINT, XTYPE, XUNTAG): Likewise, but
	hand-optimize only in the USE_LSB_TAG case, as GNUish hosts do that.
	(INTMASK, VALMASK): Now macros, since static values cannot be
	accessed from extern inline functions.
	(VALMASK): Also a constant, for benefit of old GDB.
	(LISP_INT_TAG_P): Remove; no longer needed as the only caller
	is INTEGERP, which can fold it in.
	(XLI, XIL, XHASH, XTYPE, XINT, XFASTINT, XUINT)
	(make_number, XPNTR, XUNTAG, EQ, XCONS, XVECTOR, XSTRING, XSYMBOL)
	(XFLOAT, XPROCESS, XWINDOW, XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE)
	(XSUB_CHAR_TABLE, XBOOL_VECTOR, make_lisp_ptr, CHECK_TYPE)

	(SYMBOL_BLV, SYMBOL_FWD, SET_SYMBOL_VAL, SET_SYMBOL_ALIAS)
	(SET_SYMBOL_BLV, SET_SYMBOL_FWD, SYMBOL_NAME, SYMBOL_INTERNED_P)
	(SYMBOL_INTERNED_IN_INITIAL_OBARRAY_P, SYMBOL_CONSTANT_P)
	(XHASH_TABLE, HASH_TABLE_P, CHECK_HASH_TABLE, HASH_KEY, HASH_VALUE)

	(CHECK_NUMBER_CAR, CHECK_NUMBER_CDR, CHECK_NATNUM_CAR)
	(CHECK_NATNUM_CDR, FUNCTIONP, SPECPDL_INDEX, LOADHIST_ATTACH)
	Now functions.
	(check_cons_list) [!GC_CHECK_CONS_LIST]: New empty function.
	(LISP_MAKE_RVALUE, TYPEMASK): Remove; no longer needed.
	(VALMASK): Define in one place rather than in two, merging the
	USE_LSB_TAG parts; this is simpler.
	(aref_addr, gc_aset, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM)
	(max, min, struct Lisp_String, UNSIGNED_CMP, ASCII_CHAR_P):
	Move up, to avoid use before definition.
	Also include "globals.h" earlier, for the same reason.
	(make_natnum): New function.
	(XUNTAG): Now returns void *, not intptr_t, as this means fewer casts.
	(union Lisp_Fwd, BOOLFWDP, BOOL_VECTOR_P, BUFFER_OBJFWDP, BUFFERP)
	(CHAR_TABLE_P, CHAR_TABLE_REF_ASCII, CONSP, FLOATP, INTEGERP, INTFWDP)
	(KBOARD_OBJFWDP, MARKERP, MISCP, NILP, OBJFWDP, OVERLAYP, PROCESSP)

	(initialized, Qhash_table_p, extract_float, Qprocessp, Qwindowp)
	(Qwindow_configuration_p, Qimage): New forward declarations.
	(XSETFASTINT): Simplify by rewriting in terms of make_natnum.
	(STRING_COPYIN): Remove; unused.
	(XCAR_AS_LVALUE, XCDR_AS_LVALUE): Remove these macros, replacing with ...
	(xcar_addr, xcdr_addr): New functions.  All uses changed.
	(IEEE_FLOATING_POINT): Now a constant, not a macro.
	(GLYPH, GLYPH_CHAR, GLYPH_FACE, SET_GLYPH_CHAR, SET_GLYPH_FACE)
	(SET_GLYPH, GLYPH_CODE_CHAR, GLYPH_CODE_FACE)
	(SET_GLYPH_FROM_GLYPH_CODE, GLYPH_MODE_LINE_FACE, GLYPH_CHAR_VALID_P)
	(GLYPH_CODE_P): Move to dispextern.h, to avoid define-before-use.
	(TYPE_RANGED_INTEGERP): Simplify.
	(Qsubrp, Qhash_table_p, Qoverlayp): New extern decls.
	(setlocale, fixup_locale, synchronize_system_messages_locale)
	(synchronize_system_time_locale) [!HAVE_SETLOCALE]:
	Now empty functions, not macros.
	(functionp): Return bool, not int.
	* window.c (Qwindow_configuration_p): Now extern,
	so window.h can use it.
	* window.h (Qwindowp): Move decl back to lisp.h.

2013-06-15  Eli Zaretskii  <eliz@gnu.org>

	* xdisp.c (Fline_pixel_height): New function, required for solving
	bug #14567.

2013-06-15  Paul Eggert  <eggert@cs.ucla.edu>

	* fns.c (Fcopy_sequence): Simplify XTYPE calculation.

2013-06-13  Stefan Monnier  <monnier@iro.umontreal.ca>

	* lread.c (syms_of_lread):
	* fns.c (Fprovide): Adjust to new format of after-load-alist.

2013-06-13  Kelly Dean  <kellydeanch@yahoo.com>  (tiny change)

	* fileio.c (Fdo_auto_save): Trap errors in auto-save-hook.  (Bug#14479)

2013-06-12  Xue Fuqiao  <xfq.free@gmail.com>

	* fileio.c (expand_file_name): Doc fix.

2013-06-11  Paul Eggert  <eggert@cs.ucla.edu>

	Tickle glib by waiting for Emacs itself, not for process 0 (Bug#14569).
	* process.c (init_process_emacs) [HAVE_GLIB && !WINDOWSNT]:
	Wait for self, not for 0.  This can't hurt on GNU or similar
	system, and may help with Cygwin.

	* keyboard.c: Don't use PROP (...) as an lvalue.
	(parse_tool_bar_item) [!USE_GTK && !HAVE_NS]:
	Use set_prop (A, B), not PROP (A) = B.

2013-06-10  Eli Zaretskii  <eliz@gnu.org>

	* xdisp.c (get_it_property): Use it->window instead of generating
	a Lisp object from it->w.

2013-06-09  Eli Zaretskii  <eliz@gnu.org>

	* xdisp.c (get_it_property): If it->object is a buffer, pass to
	get-char-property the window that is being rendered, instead of
	the buffer, to support window-specific overlays.  (Bug#14575)
	(compute_display_string_pos): When W is NULL, use the current
	buffer as the object to pass to get-char-property.
	(Fcurrent_bidi_paragraph_direction): Assign NULL to the window
	pointer member of the bidi iterator, since no window is pertinent
	to this function.

2013-06-08  Eli Zaretskii  <eliz@gnu.org>

	* bidi.c (bidi_fetch_char): Accept additional argument, the window
	being displayed, and pass it to compute_display_string_pos.
	(bidi_level_of_next_char, bidi_resolve_explicit_1)
	(bidi_paragraph_init): All callers changed.

	* xdisp.c (init_from_display_pos, init_iterator)
	(handle_single_display_spec, next_overlay_string)
	(get_overlay_strings_1, reseat_1, reseat_to_string)
	(push_prefix_prop, Fcurrent_bidi_paragraph_direction):
	Set bidi_it.w member from it->w.
	(compute_display_string_pos): Accept additional argument, the
	window being displayed, and pass it to Fget_char_property.
	(Bug#14575)

	* dispextern.h (struct bidi_it): New member w, the window being
	displayed.
	(compute_display_string_pos): Adjust prototype.

2013-06-08  Jan Djärv  <jan.h.d@swipnet.se>

	* xgselect.c: Remove unneeded include xterm.h.

	* process.c (wait_reading_process_output): Check for NS before GLIB.
	GLIB may be linked in due to rsvg, but ns_select must be called.

	* xgselect.c (xg_select): Remove call to window_system_available
	and g_main_context_pending at the top, so Gdk events (i.e. file
	notify) are processed when Emacs is started with -nw.

2013-06-07  Eli Zaretskii  <eliz@gnu.org>

	* Makefile.in (ctagsfiles1, ctagsfiles2): Don't include *.m files.
	(ctagsfiles3): New variable, includes only *.m files.
	(TAGS): Use an explicit language name in the regular expressions,
	to avoid transformation of '/SOMETHING' by MSYS to
	'c:\MSYS\SOMETHING'.

	configure and build with -DUNEXELF_DEBUG without worrying about
	other modules that use DEBUG.
	(DEBUG_LOG) [UNEXELF_DEBUG]: New macro.  All debug code that prints
	possibly-wide integers now uses it instead of plain fprintf.

	Don't assume ptrdiff_t, size_t, and long are the same width as int.
	(POINTER_TO_OFFSET): Return ptrdiff_t, not regoff_t.
	This matters only when DEBUG is defined.

2013-05-05  Jan Djärv  <jan.h.d@swipnet.se>

	* nsmenu.m (ns_update_menubar): Move initialization of submenuTitle

	* fileio.c (syms_of_fileio): Implement this.
	* filelock.c (create_lock_file): If symbolic links don't work, so
	we use a regular file as a lock file, do not fsync the lock file;
	it's not needed.

	* w32fns.c (w32_fullscreen_rect): New function to compute the
	window rectangle for the given fullscreen mode.
	(w32_wnd_proc): When in a fullscreen mode, WM_WINDOWPOSCHANGING no
	longer tunes the window size.  This keeps the window's edges flush
	with the screen and allows the taskbar to hide itself in fullboth.

	* w32term.c (w32fullscreen_hook): 'fullboth' now shows without
	window decorations and uses the entire screen.

	* w32term.h  (w32_fullscreen_rect) Add prototype.

	* indent.c (Fvertical_motion): Don't consider display strings on
	overlay strings as display strings on the buffer position we
	started from.  This prevents vertical cursor motion from jumping
	more than one line when there's an overlay string with a display
	property at end of line.
	Reported by Karl Chen <Karl.Chen@quarl.org> in
	http://lists.gnu.org/archive/html/emacs-devel/2013-04/msg00362.html.

	(Fwindow_line_height): Fix the test for up-to-date-ness of the
	current matrix.

2013-04-10  Eli Zaretskii  <eliz@gnu.org>

	* frame.c (do_switch_frame): Mark the TTY frame we switch to as
	garbaged only if it is not already the top frame on its TTY.
	This prevents flickering due to constant redrawing of TTY frames when
	there are GUI frames open in the same session.  (Bug#13864)

2013-04-10  Stefan Monnier  <monnier@iro.umontreal.ca>

2013-04-07  Paul Eggert  <eggert@cs.ucla.edu>

	Fix --enable-profiling bug introduced by 2013-02-25 change (Bug#13783).
	This bug was introduced by my 2013-02-25 change that simplified
	data_start configuration.  Without this change, on GNU/Linux
	an Emacs configured with --enable-profiling fails immediately
	due to a profiler signal.

	This makes it easier to visualize quantities on a number line.
	This patch doesn't apply to all such range checks,
	only to the range checks affected by the 2013-03-24 change.

	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
	activated, call w32fullscreen_hook, to make sure the new frame
	dimensions are in effect.  (Bug#13937)

2013-03-13  Dmitry Antipov  <dmantipov@yandex.ru>

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

	Static checking by Sun C 5.12.
	* alloc.c (buffer_memory_full) [REL_ALLOC]:
	* bytecode.c (exec_byte_code):
	* dispnew.c (init_display):
	* eval.c (error):
	* fileio.c (Fsubstitute_in_file_name):
	* keyboard.c (Fevent_convert_list):
	* keymap.c (Fsingle_key_description):
	* term.c (maybe_fatal, fatal):
	* xfns.c (Fx_display_backing_store, Fx_display_visual_class):
	* xsmfns.c (Fhandle_save_session):
	Omit unreachable code.
	* keymap.c (map_keymap_char_table_item): Cast void * to
	a function pointer type; the C Standard requires this.

	* sysdep.c: Remove a use of BSD_SYSTEM, which I'm trying to phase out.
	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.

See ChangeLog.12 for earlier changes.
