2011-10-25  Paul Eggert  <eggert@cs.ucla.edu>

	* dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).

2011-10-25  Stefan Monnier  <monnier@iro.umontreal.ca>

	* keyboard.c (test_undefined): New function (bug#9751).
	(read_key_sequence): Use it to detect when a key is bound to `undefined'.

2011-10-25  Enami Tsugutomo  <tsugutomo.enami@jp.sony.com>

	* sysdep.c (init_sys_modes): Fix the check for the controlling
	terminal (Bug#6649).

2011-10-20  Eli Zaretskii  <eliz@gnu.org>

	* dispextern.h (struct bidi_it): New member next_en_type.

	* bidi.c (bidi_line_init): Initialize the next_en_type member.
	(bidi_resolve_explicit_1): When next_en_pos is valid for the
	current character, check also for next_en_type being WEAK_EN.
	(bidi_resolve_weak): Don't enter the expensive loop if the current
	position is before next_en_pos.  Record the bidi type of the first
	non-ET, non-BN character we find, in addition to its position.
	(bidi_level_of_next_char): Invalidate next_en_type when
	next_en_pos is over-stepped.

2011-10-20  Paul Eggert  <eggert@cs.ucla.edu>

	Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
	* editfns.c: Rewrite current-time-zone so that it invokes
	the equivalent of (format-time-string "%Z") to get the time zone name.
	This fixes a bug when the time zone name contains characters that
	need converting from the system time locale to Emacs internal format.
	This fixes a shortcoming that I introduced in my 1999-10-19 patch:
	that patch fixed format-time-string to do the conversion, but
	I forgot to fix current-time-zone.
	(format_time_string): New function, containing most of
	what Fformat_time_string used to contain.
	(Fformat_time_string): Rewrite in terms of format_time_string.
	This doesn't change this function's behavior.
	(current-time-zone): Rewrite to use format_time_string.
	This fixes the bug reported by Michael Schierl in
	<http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
	Jason Rumney's 2007-06-07 change worked around this bug, but
	didn't fix it.
	* systime.h (tzname, timezone): Remove no-longer-used declarations.

2011-10-19  Eli Zaretskii  <eliz@gnu.org>

	* xdisp.c (start_display): If the character at POS is displayed
	via a display vector, reset IT->current.dpvec_index to zero.
	(try_window_reusing_current_matrix): If a line ends in a display
	vector or the next line starts in a display vector, continue
	redrawing the window even though the character position of
	start_row was reached.
	(Bug#9771, part 2)

2011-10-18  Chong Yidong  <cyd@gnu.org>

	* xdisp.c (get_next_display_element): Handle U+2010 and U+2011
	with nobreak-char-display too.

2011-10-18  Eli Zaretskii  <eliz@gnu.org>

	Fix part 3 of bug#9771.
	* bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
	(bidi_resolve_neutral): Don't enter the expensive loop looking for
	non-neutral characters if the current character is a paragraph
	separator (a.k.a. Newline).  This avoids running the same
	expensive loop twice, once when we consume the preceding newline
	and the other time when the line actually needs to be displayed.
	Avoid the loop when we see neutrals on the base embedding level
	following a character whose directionality is the same as the
	paragraph's.  This avoids running the expensive loop when a line
	ends in a long sequence of neutrals, like control characters.
	Add assertion against STRONG_AL type.  Slightly rearrange code
	that determines the type of a neutral given the first non-neutral
	that follows it.
	(bidi_level_of_next_char): Set next_en_pos to zero when
	invalidating its info.

2011-10-17  Eli Zaretskii  <eliz@gnu.org>

	* xdisp.c (push_display_prop): Determine whether to record string
	or buffer position by IT->string, not by IT->method.  Allow
	GET_FROM_DISPLAY_VECTOR as IT->method on entry.  (Bug#9771, part 4)
	(move_it_vertically_backward): Don't look for character position
	immediately after the newline when in a continuation line.
	(Bug#9771, part 1)

2011-10-15  Martin Rudalics  <rudalics@gmx.at>

	* window.c (coordinates_in_window): Rewrite and delabelize
	vertical border check.  (Bug#5357) (Bug#9618)

2011-10-14  Stefan Monnier  <monnier@iro.umontreal.ca>

	* xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
	errors in XSetWindowBorder (bug#9310).

2011-10-13  Dmitry Antipov  <dmantipov@yandex.ru>

	* editfns.c (Fset_time_zone_rule): Replace free with xfree to
	avoid crash when xmalloc overrun checking is enabled.

2011-10-13  Eli Zaretskii  <eliz@gnu.org>

	* xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
	itb.paragraph_dir to NEUTRAL_DIR.  Fixes an occasional incorrect
	cursor motion with <left> and <right> arrow keys.

	* bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
	some callers set that themselves.

2011-10-12  Eli Zaretskii  <eliz@gnu.org>

	* xdisp.c (find_row_edges): Handle the case where ROW comes from a
	display string and the previous row comes from the same string and
	is empty.  (Bug#9739)  (Bug#9738)

2011-10-12  Stefan Monnier  <monnier@iro.umontreal.ca>

	* doc.c (get_doc_string): Encode file name (bug#9735).

2011-10-12  Eli Zaretskii  <eliz@gnu.org>

	* bidi.c (bidi_level_of_next_char):
	* xdisp.c (get_visually_first_element): Remove old incorrect
	comments regarding the Unicode Line Separator character.

	* bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.

2011-10-12  Dmitry Antipov  <dmantipov@yandex.ru>

	* alloc.c (Fgc_status): Do not access beyond zombies array
	boundary if nzombies > MAX_ZOMBIES.
	* alloc.c (dump_zombies): Add missing format specifier.

2011-10-12  Paul Eggert  <eggert@cs.ucla.edu>

	* xdisp.c (set_cursor_from_row): Simplify conditionals,
	to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.

	* lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
	Some packages use them to denote characters with modifiers.

2011-10-11  Andreas Schwab  <schwab@linux-m68k.org>

	* lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
	(GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
	matching a pp-number.  Rename parameter var to var1.

2011-10-11  Stefan Monnier  <monnier@iro.umontreal.ca>

	* minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).

2011-10-08  Glenn Morris  <rgm@gnu.org>

	* callint.c (Fcall_interactively): Give a more explicit error for the
	'c' case with a non-character input.  (Bug#8479)

2011-10-08  Eli Zaretskii  <eliz@gnu.org>

	* xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
	lines.
	(set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
	lines that are hscrolled on the left.

	* dispnew.c (buffer_posn_from_coords): Account for a possible
	presence of header-line.  (Bug#4426)

2011-10-07  Stefan Monnier  <monnier@iro.umontreal.ca>

	* buffer.c (syms_of_buffer) <enable-multibyte-characters>:
	Don't advertise functionality which we discourage or doesn't work.

2011-10-07  Paul Eggert  <eggert@cs.ucla.edu>

	* alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
	or sizeof.  __alignof__ gives the wrong answer on Fedora x86-64
	with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
	this makes Emacs dump core during garbage collection on rare
	occasions.  sizeof is obviously inferior to offsetof here, so
	stick with offsetof.
	(GC_POINTER_ALIGNMENT): New macro.
	(mark_memory): Omit 3rd (offset) arg; caller changed.
	Don't assume EMACS_INT alignment is the same as pointer alignment.

2011-10-03  Stefan Monnier  <monnier@iro.umontreal.ca>

	* keyboard.c (read_key_sequence_remapped): New var.
	(read_key_sequence): Compute remapping in the right buffer.
	(command_loop_1): Use read_key_sequence's remapping directly.

2011-10-02  Stefan Monnier  <monnier@iro.umontreal.ca>

	* dired.c (file_name_completion): Don't expand file name.
	(Ffile_name_completion, Ffile_name_all_completions): Expand file name
	before checking file name handler.

	* minibuf.c (Finternal_complete_buffer): Only show internal buffers if
	they've been requested explicitly (bug#9591).

2011-10-01  Andreas Schwab  <schwab@linux-m68k.org>

	* keymap.c (Fsingle_key_description): Use make_specified_string
	instead of build_string to build string from push_key_description.
	(Bug#5193)

2011-09-30  Paul Eggert  <eggert@cs.ucla.edu>

	* buffer.h (struct buffer): Use time_t, not int, for a time stamp.
	This fixes a Y2038 bug on 64-bit hosts.
	* buffer.c (reset_buffer):
	* fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
	(Fclear_buffer_auto_save_failure):
	Use 0, not -1, to represent an unset failure time, since time_t
	might not be signed.

	Remove dependency on glibc malloc internals.
	* alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
	Move back here from lisp.h, but with their new implementations.
	(XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
	(XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
	* charset.c (charset_table_init): New static var.
	(syms_of_charset): Use it instead of xmalloc.  This removes a
	dependency on glibc malloc internals.  See Eli Zaretskii's comment in
	<http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
	* lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
	Move back to alloc.c.
	(XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
	(XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.

2011-09-30  Jan Djärv  <jan.h.d@swipnet.se>

	* nsterm.m (windowDidResize): Call x_set_window_size only when
	ns_in_resize is true.  Otherwise set pixelwidth/height and
	call change_frame_size (Bug#9628).

2011-09-30  Paul Eggert  <eggert@cs.ucla.edu>

	Port --enable-checking=all to Fedora 14 x86-64.
	* charset.c (syms_of_charset): Also account for glibc malloc's
	internal overhead when calculating the initial malloc maximum.

	Port --enable-checking=all to Fedora 14 x86.
	* alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
	Move to lisp.h.
	(xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
	(overrun_check_realloc, overrun_check_free):
	Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
	That way, xmalloc returns a properly-aligned pointer even if
	XMALLOC_OVERRUN_CHECK is defined.  The old debugging code happened
	to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
	* charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
	into account when calculating the initial malloc maximum.
	* lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
	Move here from alloc.c, so that charset.c can use it too.
	Properly align; the old code wasn't right for common 32-bit hosts
	when configured with --enable-checking=all.
	(XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
	(XMALLOC_OVERRUN_SIZE_SIZE): New macros.

2011-09-29  Eli Zaretskii  <eliz@gnu.org>

	* sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
	use EDOM.

2011-09-28  Eli Zaretskii  <eliz@gnu.org>

	* xdisp.c (compute_display_string_end): If there's no display
	string at CHARPOS, return -1.

	* bidi.c (bidi_fetch_char): When compute_display_string_end
	returns a negative value, treat the character as a normal
	character not covered by a display string.  (Bug#9624)

2011-09-28  Juanma Barranquero  <lekktu@gmail.com>

	* lread.c (Fread_from_string): Fix typo in docstring.

2011-09-27  Eli Zaretskii  <eliz@gnu.org>

	* xdisp.c (handle_invisible_prop): If invisible text ends on a
	newline, reseat the iterator instead of bidi-iterating there one
	character at a time.  (Bug#9610)
	(BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
	TO_CHARPOS if the bidi iterator is at base embedding level.

2011-09-27  Andreas Schwab  <schwab@linux-m68k.org>

	* lread.c (readevalloop): Use correct code for NBSP.
	(read1): Likewise.  (Bug#9608)

2011-09-25  Michael Albinus  <michael.albinus@gmx.de>

	* dbusbind.c (Fdbus_register_signal): When service is not
	registered, use nil in Vdbus_registered_objects_table.  (Bug#9581)

2011-09-25  Glenn Morris  <rgm@gnu.org>

	* buffer.c (truncate-lines): Doc fix.

2011-09-24  Chong Yidong  <cyd@stupidchicken.com>

	* window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
	(Fset_window_next_buffers): Doc fix.

2011-09-24  Glenn Morris  <rgm@gnu.org>

	* minibuf.c (read_minibuf): Disable line truncation.  (Bug#5715)

2011-09-24  Paul Eggert  <eggert@cs.ucla.edu>

	Fix minor problems found by static checking.
	* xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
	* indent.c (Fvertical_motion): Fix == vs = typo.

2011-09-24  Eli Zaretskii  <eliz@gnu.org>

	* dispnew.c (syms_of_display) <redisplay-dont-pause>:
	Default value is now t.  Doc fix.

	* indent.c (Fvertical_motion): Compute and apply the overshoot
	logic when moving up, not only when moving down.  Fix the
	confusing name and values of the it_overshoot_expected variable;
	logic changes accordingly.  (Bug#9254) (Bug#9549)

	* xdisp.c (pos_visible_p): Produce correct pixel coordinates when
	CHARPOS is covered by a display string which includes newlines.
	(move_it_vertically_backward): Avoid inflooping when START_CHARPOS
	is covered by a display string with embedded newlines.

2011-09-24  Michael Albinus  <michael.albinus@gmx.de>

	* dbusbind.c (Fdbus_register_signal): Add match rule to
	Vdbus_registered_objects_table.  (Bug#9581)
	(Fdbus_register_method, Vdbus_registered_objects_table):
	Fix docstring.

2011-09-24  Jim Meyering  <meyering@redhat.com>

	do not ignore write error for any output size
	The previous change was incomplete.
	While it makes emacs --batch detect the vast majority of stdout
	write failures, errors were still ignored whenever the output size is
	k * (BUFSIZ+1) - 4.  E.g., on a system with BUFSIZ of 4096,
	  $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
	      && echo FAIL: ignored write error
	  FAIL: ignored write error
	  $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
	      && echo FAIL: ignored write error
	  FAIL: ignored write error
	* emacs.c (Fkill_emacs): Also test ferror.  (Bug#9574)

2011-09-23  Andreas Schwab  <schwab@linux-m68k.org>

	* emacs.c (Fkill_emacs): In noninteractive mode exit
	non-successfully if a write error occurred on stdout.  (Bug#9574)

2011-09-21  Eli Zaretskii  <eliz@gnu.org>

	* xdisp.c (pop_it): Allow it->object that is a cons cell to pass
	the xassert test.

	* dispextern.h (struct it): Update the comment documenting what
	can it->OBJECT be.

2011-09-20  Eli Zaretskii  <eliz@gnu.org>

	* xdisp.c (set_cursor_from_row): If the row ends in a newline from
	a display string, extend search for cursor position to end of row.
	(find_row_edges): If the row ends in a newline from a display
	string, increment its MATRIX_ROW_END_CHARPOS by one.  (Bug#9549)
	Handle the case of a display string with multiple newlines.
	(Fcurrent_bidi_paragraph_direction): Fix search for previous
	non-empty line.  Fixes confusing cursor motion with arrow keys at
	the beginning of a line that starts with whitespace.

2011-09-19  Lars Magne Ingebrigtsen  <larsi@gnus.org>

	* lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
	(bug#9493).

2011-09-18  Chong Yidong  <cyd@stupidchicken.com>

	* xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
	boolean (Bug#9154).

2011-09-18  Eli Zaretskii  <eliz@gnu.org>

	* xdisp.c (display_line): Record maximum and minimum buffer
	positions even if no glyphs were produced (e.g., by a zero-width
	stretch).  Fixes bug#9530 on a TTY.  Under word-wrap, don't record
	buffer positions that will be removed from the glyph row because
	they don't fit.
	(produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
	column is beyond frame width: don't subtract 1 "pixel" when
	computing width of the stretch.
	(reseat_at_next_visible_line_start): Undo the change made on
	2011-09-17 that saved paragraph information and restored it after
	the call to `reseat'.  (Bug#9545)

2011-09-18  YAMAMOTO Mitsuharu  <mituharu@math.s.chiba-u.ac.jp>

	* xdisp.c (expose_window): Save original value of phys_cursor_on_p
	and turn window cursor on if cleared (Bug#9415).

2011-09-18  Andreas Schwab  <schwab@linux-m68k.org>

	* search.c (boyer_moore): Take unibyte characters from pattern
	literally.  (Bug#9458)

2011-09-18  Eli Zaretskii  <eliz@gnu.org>

	* xdisp.c (reseat_at_next_visible_line_start): Fix last change.

2011-09-18  Paul Eggert  <eggert@cs.ucla.edu>

	Fix minor problem found by static checking.
	* xdisp.c (reseat_at_next_visible_line_start): Mark locals as
	initialized, to pacify gcc -Wuninitialized.

	* fileio.c: Report proper errno when syscall falls.
	(Finsert_file_contents): Save and restore errno,
	so that report_file_error outputs the correct diagnostic.
	(Fwrite_region) [CLASH_DETECTION]: Likewise.

2011-09-18  Eli Zaretskii  <eliz@gnu.org>

	* xdisp.c (produce_stretch_glyph): Another fix for changes made on
	2011-08-30T17:32:44Z!eliz@gnu.org.  (Bug#9530)

2011-09-17  Eli Zaretskii  <eliz@gnu.org>

	* xdisp.c (reseat_at_next_visible_line_start): Keep information
	about the current paragraph and restore it after the call to reseat.

	* bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
	(bidi_find_paragraph_start): Search back for paragraph beginning
	at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
	(bidi_move_to_visually_next): Only trigger paragraph-related
	computations when the last character is a newline or at EOB, not
	just any NEUTRAL_B.  (Bug#9470)

	* xdisp.c (set_cursor_from_row): Don't invoke special treatment of
	truncated lines if point is covered by a display string.  (Bug#9524)

2011-09-16  Paul Eggert  <eggert@cs.ucla.edu>

	* xselect.c: Relax test for outgoing X longs (Bug#9498).
	(cons_to_x_long): New function.
	(lisp_data_to_selection_data): Use it.  Correct the test for
	short-versus-long data; it was negated.  Break out of vector
	loop, for efficiency, when a long datum is discovered.

2011-09-16  Stefan Monnier  <monnier@iro.umontreal.ca>

	* eval.c (Fquote): Document its non-consing behavior (bug#9482).

	of TAB characters in a composition.

2011-09-15  Paul Eggert  <eggert@cs.ucla.edu>

	* editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).

	Problem reported by Wolfgang Jenker.

2011-09-15  Johan Bockgård  <bojohan@gnu.org>

	* xdisp.c (try_cursor_movement): Only check for exact match if

	* xselect.c: Use signed conversions more consistently (Bug#9498).
	(selection_data_to_lisp_data): Assume incoming selection data are
	signed integers, not unsigned.  This is to be consistent with
	outgoing selection data, which was modified to use signed integers
	in as part of the fix to Bug#9196 in response to Jan D.'s comment
	in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11

2011-09-14  Eli Zaretskii  <eliz@gnu.org>

	* xdisp.c (try_window_reusing_current_matrix): Fix incorrect
	computation of loop end.  Reported by Johan Bockgård
	<bojohan@gnu.org>.

2011-09-13  Chong Yidong  <cyd@stupidchicken.com>

	* frame.c (Fother_visible_frames_p): Function deleted.

2011-09-12  Eli Zaretskii  <eliz@gnu.org>

	* indent.c (compute_motion): Process display vector front to back
	rather than the other way around.  (Bug#2496)

2011-09-12  Stefan Monnier  <monnier@iro.umontreal.ca>

	* fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.

2011-09-11  Chong Yidong  <cyd@stupidchicken.com>

	* minibuf.c (Fread_from_minibuffer): Doc fix.

2011-09-11  Eli Zaretskii  <eliz@gnu.org>

2011-09-11  Lars Magne Ingebrigtsen  <larsi@gnus.org>

	* fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
	value for non-existent files.

2011-09-11  Eli Zaretskii  <eliz@gnu.org>

	* fileio.c (Finsert_file_contents): If the file cannot be opened,
	set its "size" to -1.  This will set the modtime_size field of
	the corresponding buffer to -1, which is what
	verify-visited-file-modtime expects for files that do not exist.
	(Bug#9139)

2011-09-11  Paul Eggert  <eggert@cs.ucla.edu>

	* keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
	here ...
	* lisp.h: ... from here.  push_key_description is no longer
	defined in keyboard.c, so its declaration should not be in
	lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
	logically belongs with push_key_description.

2011-09-10  Paul Eggert  <eggert@cs.ucla.edu>

	* buffer.h: Include <sys/types.h> instead of <time.h>.
	Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
	Problem reported by Herbert J. Skuhra.

2011-09-10  Lars Magne Ingebrigtsen  <larsi@gnus.org>

	* xml.c (parse_region): Make the parsing work for
	non-comment-starting XML files again (bug#9144).

2011-09-10  Andreas Schwab  <schwab@linux-m68k.org>

	* image.c (gif_load): Fix calculation of bottom and right corner.
	(Bug#9468)

2011-09-10  Eli Zaretskii  <eliz@gnu.org>

	* xdisp.c (MAX_DISP_SCAN): Decrease to 250.  Prevents sluggish
	redisplay in small windows.

2011-09-09  Eli Zaretskii  <eliz@gnu.org>

	* frame.c (x_report_frame_params): Cast to avoid compiler warnings.

2011-09-08  Martin Rudalics  <rudalics@gmx.at>

	* window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
	Operate on live windows only.

2011-09-08  Juanma Barranquero  <lekktu@gmail.com>

	* emacs.c (my_heap_start): #ifdef to avoid warnings when unused.

2011-09-07  Eli Zaretskii  <eliz@gnu.org>

	* xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
	only under bidi iteration.

2011-09-07  Jan Djärv  <jan.h.d@swipnet.se>

	* gtkutil.c (xg_make_tool_item): Insert comment about eventbox.

2011-09-06  Paul Eggert  <eggert@cs.ucla.edu>

	isnan: Fix porting problem to Solaris 10 with bundled gcc.
	Without this fix, the command to link temacs failed due to an
	undefined symbol __builtin_isnan.  This is because
	/usr/include/iso/math_c99.h #defines isnan(x) to
	__builtin_isnan(x), but the bundled gcc, which identifies itself
	as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
	a __builtin_isnan.
	* floatfns.c (isnan): #undef, and then #define to a clone of
	what's in data.c.
	(Fisnan): Always define, since it's always available now.
	(syms_of_floatfns): Always define isnan at the Lisp level.

2011-09-06  Paul Eggert  <eggert@cs.ucla.edu>

	* Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).

2011-09-06  Paul Eggert  <eggert@cs.ucla.edu>

	* fileio.c: Fix bugs with large file offsets (Bug#9428).
	The previous code assumed that file offsets (off_t values) fit in
	EMACS_INT variables, which is not true on typical 32-bit hosts.
	The code messed up by falsely reporting buffer overflow in cases
	such as (insert-file-contents "big" nil 1 2) into an empty buffer
	when "big" contains more than 2**29 bytes, even though this
	inserts just one byte and does not overflow the buffer.
	(Finsert_file_contents): Store file offsets as off_t
	values, not as EMACS_INT values.  Check for overflow when
	converting between EMACS_INT and off_t.  When checking for
	buffer overflow or for overlap, take the offsets into account.
	Don't use EMACS_INT for small values where int suffices.
	When checking for overlap, fix a typo: ZV was used where
	ZV_BYTE was intended.
	(Fwrite_region): Don't assume off_t fits into 'long'.
	* buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.

2011-09-05  Michael Albinus  <michael.albinus@gmx.de>

	* dbusbind.c (xd_signature_cat): Rename from signature_cat.

2011-09-04  Paul Eggert  <eggert@cs.ucla.edu>

	sprintf-related integer and memory overflow issues (Bug#9412).

	* doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
	(esprintf, exprintf, evxprintf): New functions.
	* keyboard.c (command_loop_level): Now EMACS_INT, not int.
	(cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
	(modify_event_symbol): Do not assume that the length of
	name_alist_or_stem is safe to alloca and fits in int.
	(Fexecute_extended_command): Likewise for function name and binding.
	(Frecursion_depth): Wrap around reliably on integer overflow.
	* keymap.c (push_key_description): First arg is now EMACS_INT, not int,
	since some callers pass EMACS_INT values.
	(Fsingle_key_description): Don't crash if symbol name contains more
	than MAX_ALLOCA bytes.
	* minibuf.c (minibuf_level): Now EMACS_INT, not int.
	(get_minibuffer): Arg is now EMACS_INT, not int.
	* lisp.h (get_minibuffer, push_key_description): Reflect API changes.
	(esprintf, exprintf, evxprintf): New decls.
	* window.h (command_loop_level, minibuf_level): Reflect API changes.

	* dbusbind.c (signature_cat): New function.
	(xd_signature, Fdbus_register_signal):
	Do not overrun buffer; instead, report string overflow.

	* dispnew.c (add_window_display_history): Don't overrun buffer.
	Truncate instead; this is OK since it's just a log.

	* editfns.c (Fcurrent_time_zone): Don't overrun buffer
	even if the time zone offset is outlandishly large.
	Don't mishandle offset == INT_MIN.

	* emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
	when creating daemon; the previous buffer-overflow check was incorrect.

	* eval.c (verror): Simplify by rewriting in terms of evxprintf,
	which has the guts of the old verror function.

	* filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
	use SAFE_ALLOCA instead.  Use esprintf to avoid int-overflow issues.

	* font.c: Include <float.h>, for DBL_MAX_10_EXP.
	(font_unparse_xlfd): Don't blindly alloca long strings.
	Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
	fits in int, when using sprintf.  Use single snprintf to count
	length of string rather than counting it via multiple sprintfs;
	that's simpler and more reliable.
	(font_unparse_fcname): Use it to avoid sprintf buffer overrun.
	(generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
	sprintf, in case result does not fit in int.

	* fontset.c (num_auto_fontsets): Now printmax_t, not int.
	(fontset_from_font): Print it.

	* frame.c (tty_frame_count): Now printmax_t, not int.
	(make_terminal_frame, set_term_frame_name): Print it.
	(x_report_frame_params): In X, window IDs are unsigned long,
	not signed long, so print them as unsigned.
	(validate_x_resource_name): Check for implausibly long names,
	and don't assume name length fits in 'int'.
	(x_get_resource_string): Don't blindly alloca invocation name;
	use SAFE_ALLOCA.  Use esprintf, not sprintf, in case result does
	not fit in int.

	* gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
	(xg_check_special_colors, xg_set_geometry):
	Make sprintf buffers a bit bigger, to avoid potential buffer overrun.

	* lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
	Use esprintf, not sprintf, in case result does not fit in int.

	* macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
	(Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
	it as a large positive number.
	(Fexecute_kbd_macro): Don't assume repeat count fits in int.
	* macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.

	* nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
	in case result does not fit in int.

	* print.c (float_to_string): Detect width overflow more reliably.
	(print_object): Make sprintf buffer a bit bigger, to avoid potential
	buffer overrun.  Don't assume list length fits in 'int'.  Treat
	print length of 0 as 0, not as infinity; to be consistent with other
	uses of print length in this function.  Don't overflow print length
	index.  Don't assume hash table size fits in 'long', or that
	vectorlike size fits in 'unsigned long'.

	* process.c (make_process): Use printmax_t, not int, to format
	process-name gensyms.

	* sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.

	* term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
	to avoid potential buffer overrun.

	to avoid potential buffer overrun.

	* xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.

	* xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.

2011-09-04  Paul Eggert  <eggert@cs.ucla.edu>

	Integer overflow fixes for scrolling, etc.
	Without these, Emacs silently mishandles large integers sometimes.
	For example, "C-u 4294967297 M-x recenter" was treated as if
	it were "C-u 1 M-x recenter" on a typical 64-bit host.

	* xdisp.c (try_window_id): Check Emacs fixnum range before
	converting to 'int'.

	* window.c (window_scroll_line_based, Frecenter):
	Check that an Emacs fixnum is in range before assigning it to 'int'.
	(Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
	values converted from Emacs fixnums.
	(Frecenter): Don't wrap around a line count if it is out of 'int'
	range; instead, treat it as an extreme value.
	(Fset_window_configuration, compare_window_configurations):
	Use ptrdiff_t, not int, for index that might exceed 2 GiB.

	* search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
	that can exceed INT_MAX.  Check that EMACS_INT value is in range
	before assigning it to the (possibly-narrower) index.
	(match_limit): Don't assume that a fixnum can fit in 'int'.

	* print.c (print_object): Use ptrdiff_t, not int, for index that can
	exceed INT_MAX.

	* indent.c (position_indentation): Now takes ptrdiff_t, not int.
	(Fvertical_motion): Don't wrap around LINES values that don't fit
	in 'int'.  Instead, treat them as extreme values.  This is good
	enough for windows, which can't have more than INT_MAX lines anyway.

2011-09-03  Lars Magne Ingebrigtsen  <larsi@gnus.org>

	* Require libxml/parser.h to avoid compilation warning.

	* emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.

	* xml.c (parse_region): Don't call xmlCleanupParser after parsing,
	since this reportedly can destroy thread storage.

2011-08-30  Chong Yidong  <cyd@stupidchicken.com>

	* syntax.c (find_defun_start): Update all cache variables if
	exiting early (Bug#9401).

	* image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.

	* xdisp.c (produce_stretch_glyph): No longer static, compiled also
	when HAVE_WINDOW_SYSTEM is not defined.  Support both GUI and TTY
	frames.  Call tty_append_glyph in the TTY case.  (Bug#9402)

	* term.c (tty_append_glyph): New function.
	(produce_stretch_glyph): Static function and its prototype deleted.

	* dispextern.h (produce_stretch_glyph, tty_append_glyph):
	Add prototypes.

2011-08-29  Paul Eggert  <eggert@cs.ucla.edu>

	* image.c (parse_image_spec): Check for nonnegative, not for positive,
	when checking :margin (Bug#9390).
	(IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
	Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
	so that the name doesn't mislead.  All uses changed.

2011-08-28  Johan Bockgård  <bojohan@gnu.org>

	* term.c (init_tty) [HAVE_GPM]: Move mouse settings after
	set_tty_hooks.

2011-08-27  Eli Zaretskii  <eliz@gnu.org>

	* xdisp.c (move_it_to): Don't bail out early when reaching
	position beyond to_charpos, if we are scanning backwards.
	(move_it_vertically_backward): When DY == 0, make sure we get to
	the first character in the line after the newline.

2011-08-27  Paul Eggert  <eggert@cs.ucla.edu>

	* ccl.c: Improve and simplify overflow checking (Bug#9196).
	(ccl_driver): Do not generate an out-of-range pointer.
	(Fccl_execute_on_string): Remove unnecessary check for
	integer overflow, noted by Stefan Monnier in

	Remove a FIXME that didn't need fixing.
	Simplify the newly-introduced buffer reallocation code.

2011-08-27  Juanma Barranquero  <lekktu@gmail.com>

	* makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.

2011-08-26  Paul Eggert  <eggert@cs.ucla.edu>

	Integer and memory overflow issues (Bug#9196).

	* doc.c (get_doc_string): Rework so that
	get_doc_string_buffer_size is the actual buffer size, rather than
	being 1 less than the actual buffer size; this makes xpalloc more
	convenient.

	* image.c (x_allocate_bitmap_record, cache_image):
	* xselect.c (Fx_register_dnd_atom):
	Simplify previous changes by using xpalloc.

	* buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
	since either will do and ptrdiff_t is convenient with xpalloc.

	(charset_compare): Don't overflow if priorities differ greatly.
	(Fsort_charsets): Don't assume list length fits in int.
	Check for size-calculation overflow when allocating sort data.

	* cmds.c (internal_self_insert): Check for size-calculation overflow.

	* composite.h (struct composition.glyph_len): Now int, not unsigned.
	The actual value is always <= INT_MAX, and leaving it unsigned made
	overflow checking harder.

	* dispextern.h (struct glyph_matrix.rows_allocated)
	(struct face_cache.size): Now ptrdiff_t, for convenience in use
	with xpalloc.  The values are still always <= INT_MAX.

	* indent.c (compute_motion): Adjust to region_cache_forward sig change.

	* lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
	(SAFE_NALLOCA): New macro.

	(set_cache_region, invalidate_region_cache)
	(revalidate_region_cache, know_region_cache, region_cache_forward)
	(region_cache_backward, pp_cache):
	Use ptrdiff_t, not EMACS_INT, since either will do.  This is needed
	so that ptrdiff_t * can be passed to xpalloc.
	(struct region_cache): Similarly, for gap_start, gap_len, cache_len,
	beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
	(pp_cache): Don't assume cache_len fits in int.
	* region-cache.h: Adjust extern decls to match.

	* search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
	EMACS_INT, since either will do, for xpalloc.

	* bidi.c (bidi_cache_shrink):
	* buffer.c (overlays_at, overlays_in, record_overlay_string)
	(overlay_strings):
	Don't update size of array until after memory allocation succeeds,
	because xmalloc/xrealloc may not return.
	(struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
	now that we have proper integer overflow checking.
	(record_overlay_string, overlay_strings): Catch overflows when
	calculating size of overlay_str_buf.

	* callproc.c (Fcall_process): Check for size overflow when
	calculating size of args2.
	(child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
	Normally we prefer signed values, but sticking with ptrdiff_t would
	require adding more-complicated checks.

	* ccl.c (Fccl_execute_on_string): Check for memory overflow.
	Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
	Redo buffer-overflow calculations to avoid integer overflow.
	Add a FIXME comment where memory seems to be over-allocated.

	* character.c (Fstring): Check for size-calculation overflow.

	* coding.c (produce_chars): Redo buffer-overflow calculations to avoid
	unnecessary integer overflow.  Check for size overflow.

	length calculations.

	Integer and memory overflow fixes for display code.
	* dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
	* dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
	(scrolling_window): Check for overflow in size calculations.

	(row_table_size): Now ptrdiff_t, not int.
	(scrolling_window): Avoid overflow in size calculations.
	Don't update size until allocation succeeds.
	* fns.c (concat): Check for overflow in size calculations.

	fits in int.
	(message_length): Now ptrdiff_t, not int.

	Don't assume message length fits in int.
	(Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.

	* emacs.c (main): Do not reallocate argv, since there is a null at
	the end that can be overwritten, and this way there's no need to
	worry about size-calculation overflow.
	(sort_args): Check for size-calculation overflow.

	* eval.c (init_eval_once, grow_specpdl): Don't update size until
	alloc succeeds.
	(call_debugger, grow_specpdl): Redo calculations to avoid overflow.

	* frame.c (set_menu_bar_lines, x_set_frame_parameters)
	(x_set_scroll_bar_width, x_figure_window_size):
	Check for integer overflow.
	(x_set_alpha): Do not assume XINT fits in int.

	* frame.h (struct frame): Use int, not EMACS_INT, where int works.
	This is for the members text_lines, text_cols, total_lines, total_cols,
	where the system imposes an 'int' limit.

	* fringe.c (Fdefine_fringe_bitmap):
	Don't update size until alloc works.

	* ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
	(ftfont_shape_by_flt): Check for integer overflow in size calculations.

	* gtkutil.c (get_utf8_string, xg_store_widget_in_map):
	Check for size-calculation overflow.
	(get_utf8_string): Use ptrdiff_t, not size_t, where either will

	Use and return ptrdiff_t, not int.
	(xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
	* gtkutil.h: Change prototypes to match the above.

	* image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
	are duplicate now that they've been promoted to lisp.h.
	(x_allocate_bitmap_record, x_alloc_image_color)
	(make_image_cache, cache_image, xpm_load):
	Don't update size until alloc is done.

	calculations, and distinguish size from memory overflow better.
	(receive_incremental_selection): When tracing, don't assume
	unsigned int is less than INT_MAX.
	(x_selection_data_to_lisp_data): Remove unnecessary (and in theory

	in the range -65535 through -1 fit in an X unsigned short.
	Don't assume that ULONG_MAX == X_ULONG_MAX.  Don't store into
	result parameters unless successful.  Rely on cons_to_unsigned

	Prefer int to unsigned where either will do.
	(tiff_handler): New function, combining the cores of the
	old tiff_error_handler and tiff_warning_handler.

	continuation rows.  Fixes unwarranted scroll when point enters a
	continued line of R2L text within an L2R paragraph, or vice versa.
	(cursor_row_p): Consider the case of point being equal to
	MATRIX_ROW_END_CHARPOS.  Prevents cursor being stuck when moving

	in a buffer produced by `describe-categories'.

	* dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
	members before the level stack, so they would be saved and
	restored when copying iterator state.  Fixes incorrect reordering

	when IT->position is set up wrongly due to some bug.
	Set IT->current to match the bidi iterator unconditionally.
	(push_display_prop): Allow GET_FROM_STRING as IT->method on
	entry.  Force push_it to save on the stack the current

	the font entity extracted from the cache (Bug#8109).

2011-08-07  Chong Yidong  <cyd@stupidchicken.com>

	* composite.c (autocmp_chars): Don't reset point.  That is done by
	restore_point_unwind (Bug#5984).

2011-08-07  Juri Linkov  <juri@jurta.org>

	* editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
	to show the arg `TIME' instead of `TIMEVAL'.

2011-08-06  Eli Zaretskii  <eliz@gnu.org>

	* xdisp.c (set_cursor_from_row): Fix cursor positioning when a
	display property strides EOL and includes a newline, as in
	longlines-mode.  (Bug#9254)
	(move_it_in_display_line_to): Fix vertical-motion in a buffer with
	word-wrap under bidirectional display.  (Bug#9224)

	* bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
	is non-zero, even if the data buffer is NULL.  Fixes a crash in
	vertical-motion with longlines-mode.  (Bug#9254)

2011-08-05  Eli Zaretskii  <eliz@gnu.org>

	* bidi.c <bidi_cache_total_alloc>: Now static.
	(bidi_initialize): Initialize bidi_cache_total_alloc.

	* xdisp.c (display_line): Release buffer allocated for shelved bidi
	cache.  (Bug#9221)

	* bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
	amount allocated this far in `bidi_cache_total_alloc'.
	(bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
	non-zero, only free the data buffer without restoring the cache
	contents.  All callers changed.

	* dispextern.h (bidi_unshelve_cache): Update prototype.

	* xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
	(move_it_in_display_line, move_it_to)
	(move_it_vertically_backward, move_it_by_lines): Replace the call
	to xfree to an equivalent call to bidi_unshelve_cache.
	(move_it_in_display_line_to): Fix logic of returning
	MOVE_POS_MATCH_OR_ZV in the bidi case.  (Bug#9224)

2011-08-05  Eli Zaretskii  <eliz@gnu.org>

	* xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
	came from a string character with a `cursor' property.  (Bug#9229)

2011-08-04  Jan Djärv  <jan.h.d@swipnet.se>

	* Makefile.in (LIB_PTHREAD): New variable.
	(LIBES): Add LIB_PTHREAD (Bug#9216).

	* alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
	Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).

2011-08-04  Andreas Schwab  <schwab@linux-m68k.org>

	* regex.c (re_iswctype): Remove some redundant boolean conversions.

2011-08-04  Jan Djärv  <jan.h.d@swipnet.se>

	* xterm.c (x_find_topmost_parent): New function.
	(x_set_frame_alpha): Find topmost parent window with

	so that it is not optimized away.

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

2011-08-02  Eli Zaretskii  <eliz@gnu.org>

	Fix slow cursor motion and scrolling in large buffers with
	selective display, like Org Mode buffers.  (Bug#9218)

	* dispextern.h (struct bidi_it): New member disp_prop_p.

	* xdisp.c: Remove one-slot cache of display string positions.
	(compute_display_string_pos): Accept an additional argument
	DISP_PROP_P; callers changed.  Scan at most 5K characters forward
	for a display string or property.  If found, set DISP_PROP_P
	non-zero.

	* bidi.c (bidi_fetch_char): Accept an additional argument
	DISP_PROP_P, and pass it to compute_display_string_pos.
	Only handle text covered by a display string if DISP_PROP_P is returned
	non-zero.  All callers of bidi_fetch_char changed.

2011-08-02  Stefan Monnier  <monnier@iro.umontreal.ca>

	* keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.

2010-12-03  Don March  <don@ohspite.net>

	* keymap.c (Fdefine_key): Fix non-prefix key error message when
	last character M-[char] is translated to ESC [char] (bug#7541).

2011-08-02  Kenichi Handa  <handa@m17n.org>

	* lisp.h (uniprop_table): Extern it.

	* chartab.c (uniprop_table): Make it non-static.

2011-08-01  Eli Zaretskii  <eliz@gnu.org>

	* xdisp.c (forward_to_next_line_start): Accept additional argument
	BIDI_IT_PREV, and store into it the state of the bidi iterator had
	on the newline.
	(reseat_at_next_visible_line_start): Use the bidi iterator state
	returned by forward_to_next_line_start to restore the state of
	it->bidi_it after backing up to previous newline.  (Bug#9212)

2011-07-30  Andreas Schwab  <schwab@linux-m68k.org>

	* regex.c (re_comp): Protoize.
	(re_exec): Fix return type.
	(regexec): Fix type of `ret'.  (Bug#9203)

2011-07-28  Paul Eggert  <eggert@cs.ucla.edu>

	* image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
	This is needed if max-image-size is a floating-point number.

2011-07-28  Andreas Schwab  <schwab@linux-m68k.org>

	* print.c (print_object): Print empty symbol as ##.

	* lread.c (read1): Read ## as empty symbol.

2011-07-28  Alp Aker  <alp.tekin.aker@gmail.com>

	* nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
	setting frame foreground color (Bug#9175).
	(x_set_background_color): Likewise.

	* nsmenu.m (-setText): Size tooltip dimensions precisely to
	contents (Bug#9176).
	(EmacsTooltip -init): Remove bezels and add shadows to
	tooltip windows.

	* nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
	or scroll bar (Bug#8470).

	* nsfont.m (nsfont_open): Remove assignment to voffset and
	unnecessary vars hshink, expand, hd, full_height, min_height.
	(nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).

	* nsterm.h (nsfont_info): Remove voffset field.

2011-07-28  Alp Aker  <alp.tekin.aker@gmail.com>

	Implement strike-through and overline on NextStep (Bug#8863).

	* nsfont.m (nsfont_open): Use underline position provided by font,
	instead of hard-coded value of 2.
	(nsfont_draw): Call ns_draw_text_decoration instead.

	* nsterm.h: Add declaration for ns_draw_text_decoration.

	* nsterm.m (ns_draw_text_decoration): New function for drawing
	underline, overline, and strike-through.
	(ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
	ns_draw_text_decoration.  Change treatment of cursor drawing to
	accommodate underlining, etc.

2011-07-28  Eli Zaretskii  <eliz@gnu.org>

	* buffer.c (init_buffer_once): Set bidi-display-reordering to t by
	default.

2011-07-28  Paul Eggert  <eggert@cs.ucla.edu>

	* alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
	Without this fix, if a signal arrives just after memory fills up,
	'malloc' might be invoked reentrantly.

	* image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
	In other words, assume that every image size is allowed, on non-X
	hosts.  This assumption is probably wrong, but it lets Emacs compile.

2011-07-28  Andreas Schwab  <schwab@linux-m68k.org>

	* regex.c (re_iswctype): Convert return values to boolean.

2011-07-28  Eli Zaretskii  <eliz@fencepost.gnu.org>

	* xdisp.c (compute_display_string_pos): Don't use cached display
	string position if the buffer had its restriction changed.
	(Bug#9184)

2011-07-28  Paul Eggert  <eggert@cs.ucla.edu>

	* callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.

2011-07-28  Paul Eggert  <eggert@cs.ucla.edu>

	Integer signedness and overflow and related fixes.  (Bug#9079)

	* bidi.c: Integer size and overflow fixes.
	(bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
	(bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
	(bidi_cache_find_level_change, bidi_cache_ensure_space)
	(bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
	(bidi_find_other_level_edge):
	Use ptrdiff_t instead of EMACS_INT where either will do.
	This works better on 32-bit hosts configured --with-wide-int.
	(bidi_cache_ensure_space): Check for size-calculation overflow.
	Use % rather than repeated addition, for better worst-case speed.
	Don't set bidi_cache_size until after xrealloc returns, because it
	might not return.
	(bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
	(bidi_cache_ensure_space): Also check that the bidi cache size
	does not exceed that of the largest Lisp string or buffer.  See Eli
	Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.

	* alloc.c (__malloc_size_t): Remove.
	All uses replaced by size_t.  See Andreas Schwab's note
	<http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.

	* image.c: Improve checking for integer overflow.
	(check_image_size): Assume that f is nonnull, since
	it is always nonnull in practice.  This is one less thing to
	worry about when checking for integer overflow later.
	(x_check_image_size): New function, which checks for integer
	overflow issues inside X.
	(x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
	This removes the need for a memory_full check.
	(xbm_image_p): Rewrite to avoid integer multiplication overflow.
	(Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
	(xbm_read_bitmap_data): Change locals back to 'int', since
	their values must fit in 'int'.
	(xpm_load_image, png_load, tiff_load):
	Invoke x_create_x_image_and_pixmap earlier,
	to avoid much needless work if the image is too large.
	(tiff_load): Treat overly large images as if
	x_create_x_image_and_pixmap failed, not as malloc failures.
	(gs_load): Use x_check_image_size.

	* gtkutil.c: Omit integer casts.
	(xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
	(xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.

	* image.c (png_load): Don't assume height * row_bytes fits in 'int'.

	* xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
	Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
	would wrongly return t on a 64-bit host.

	* dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
	The plain *_OVERFLOW macros run afoul of GCC bug 49705
	<http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
	and therefore cause GCC to emit a bogus diagnostic in some cases.

	* image.c: Integer signedness and overflow and related fixes.
	This is not an exhaustive set of fixes, but it's time to
	record what I've got.
	(lookup_pixel_color, check_image_size): Remove redundant decls.
	(check_image_size): Don't assume that arbitrary EMACS_INT values
	fit in 'int', or that arbitrary 'double' values fit in 'int'.
	(x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
	(tiff_load, imagemagick_load_image):
	Check for overflow in size calculations.
	(x_create_x_image_and_pixmap): Remove unnecessary test for
	xmalloc returning NULL; that can't happen.
	(xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
	(xpm_color_bucket): Use better integer hashing function.
	(xpm_cache_color): Don't possibly over-allocate memory.
	(struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
	(gif_memory_source):
	Use ptrdiff_t, not int or size_t, to record sizes.
	(png_load): Don't assume values greater than 2**31 fit in 'int'.
	(our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
	either works, as we prefer signed integers.
	(tiff_read_from_memory, tiff_write_from_memory):
	Return tsize_t, not size_t, since that's what the TIFF API wants.
	(tiff_read_from_memory): Don't fail simply because the read would
	go past EOF; instead, return a short read.
	(tiff_load): Omit no-longer-needed casts.
	(Fimagemagick_types): Don't assume size fits into 'int'.

	Improve hashing quality when configured --with-wide-int.
	* fns.c (hash_string): New function, taken from sxhash_string.
	Do not discard information about ASCII character case; this
	discarding is no longer needed.
	(sxhash-string): Use it.  Change sig to match it.  Caller changed.
	* lisp.h: Declare it.
	* lread.c (hash_string): Remove, since we now use fns.c's version.
	The fns.c version returns a wider integer if --with-wide-int is
	specified, so this should help the quality of the hashing a bit.

	* emacs.c: Integer overflow minor fix.
	(heap_bss_diff): Now uprintmax_t, not unsigned long.  All used changed.
	Define only if GNU_LINUX.
	(main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.

	* dispnew.c: Integer signedness and overflow fixes.
	Remove unnecessary forward decls, that were a maintenance hassle.
	(history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
	All uses changed.
	(adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
	(scrolling_window): Use ptrdiff_t, not int, for byte count.
	(prepare_desired_row, line_draw_cost):
	Use int, not unsigned, where either works.
	(save_current_matrix, restore_current_matrix):
	Use ptrdiff_t, not size_t, where either works.
	(init_display): Check for overflow more accurately, and without
	relying on undefined behavior.

	* editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
	Remove, replacing with the new symbols in lisp.h.  All uses changed.
	* fileio.c (make_temp_name):
	* filelock.c (lock_file_1, lock_file):
	* xdisp.c (message_dolog):
	Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
	Use pMd etc. instead.
	* lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
	replacing the pWIDE etc. symbols removed from editfns.c.

	* keyboard.h (num_input_events): Now uintmax_t.
	This is (very slightly) less likely to mess up due to wraparound.
	All uses changed.

	* buffer.c: Integer signedness fixes.
	(alloc_buffer_text, enlarge_buffer_text):
	Use ptrdiff_t rather than size_t when either will do, as we prefer
	signed integers.

	* alloc.c: Integer signedness and overflow fixes.
	Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
	(__malloc_size_t): Default to size_t, not to int.
	(pure_size, pure_bytes_used_before_overflow, stack_copy_size)
	(Fgarbage_collect, mark_object_loop_halt, mark_object):
	Prefer ptrdiff_t to size_t when either would do, as we prefer
	signed integers.
	(XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
	(xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
	Now const.  Initialize with values that are in range even if char
	is signed.
	(XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
	(xmalloc_put_size, xmalloc_get_size): New functions.  All uses changed.
	These functions do the right thing with sizes > 2**32.
	(check_depth): Now ptrdiff_t, not int.
	(overrun_check_malloc, overrun_check_realloc, overrun_check_free):
	Adjust to new way of storing sizes.  Check for size overflow bugs
	in rest of code.
	(STRING_BYTES_MAX): Adjust to new overheads.  The old code was
	slightly wrong anyway, as it missed one instance of
	XMALLOC_OVERRUN_CHECK_OVERHEAD.
	(refill_memory_reserve): Omit needless cast to size_t.
	(mark_object_loop_halt): Mark as externally visible.

	* xselect.c: Integer signedness and overflow fixes.
	(Fx_register_dnd_atom, x_handle_dnd_message):
	Use ptrdiff_t, not size_t, since we prefer signed.
	(Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
	* xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
	x_dnd_atoms_size and x_dnd_atoms_length.

	* doprnt.c: Prefer signed to unsigned when either works.
	* eval.c (verror):
	* doprnt.c (doprnt):
	* lisp.h (doprnt):
	* xdisp.c (vmessage):
	Use ptrdiff_t, not size_t, when using or implementing doprnt,
	since the sizes cannot exceed ptrdiff_t bounds anyway, and we
	prefer signed arithmetic to avoid comparison confusion.
	* doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
	but is a bit tricky.

	Assume freestanding C89 headers, string.h, stdlib.h.
	* data.c, doprnt.c, floatfns.c, print.c:
	Include float.h unconditionally.
	* gmalloc.c: Assume C89-at-least behavior for preprocessor,
	limits.h, stddef.h, string.h.  Use memset instead of 'flood'.
	* regex.c: Likewise for stddef.h, string.h.
	(ISASCII): Remove; can assume it returns 1 now.  All uses removed.
	* s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
	* s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
	(STDC_HEADERS): Remove obsolete defines.
	* sysdep.c: Include limits.h unconditionally.

	Assume support for memcmp, memcpy, memmove, memset.
	* lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
	* regex.c (memcmp, memcpy):
	Remove; we assume C89 now.

	* gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
	(__malloc_safe_bcopy): Remove; no longer needed.

	* lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
	Use EMACS_INT, not EMACS_UINT, for sizes.  The code works equally
	well either way, and we prefer signed to unsigned.

2011-07-27  Lars Magne Ingebrigtsen  <larsi@gnus.org>

	* gnutls.c (emacs_gnutls_read): Don't message anything if the peer
	closes the connection while we're reading (bug#9182).

2011-07-25  Jan Djärv  <jan.h.d@swipnet.se>

	* nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
	are specified (Bug#9168).

2011-07-25  Paul Eggert  <eggert@cs.ucla.edu>

	* bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
	Found by GCC static checking and --with-wide-int on a 32-bit host.

2011-07-25  Eli Zaretskii  <eliz@gnu.org>

	* xdisp.c (compute_display_string_pos): Fix logic of caching
	previous display string position.  Initialize cached_prev_pos to
	-1.  Fixes slow-down at the beginning of a buffer.

2011-07-24  Eli Zaretskii  <eliz@gnu.org>

	* xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
	for attrs[LFACE_FONTSET_INDEX].

2011-07-23  Paul Eggert  <eggert@cs.ucla.edu>

	* xml.c (parse_region): Remove unused local
	that was recently introduced.

2011-07-23  Eli Zaretskii  <eliz@gnu.org>

	* xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
	2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.

	* xdisp.c (move_it_in_display_line_to): Record the best matching
	position for TO_CHARPOS while scanning the line, and restore it on
	exit if none of the characters scanned was an exact match.
	Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
	when exact match is impossible due to invisible text, and the
	lines are truncated.

2011-07-23  Jan Djärv  <jan.h.d@swipnet.se>

	* nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
	for OSX >= 10.7.

2011-07-22  Eli Zaretskii  <eliz@gnu.org>

	Fix a significant slow-down of cursor motion with C-n, C-p,
	C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
	auto-repeat under bidi redisplay in fontified buffers.
	* xdisp.c (compute_stop_pos_backwards): New function.
	(next_element_from_buffer): Call compute_stop_pos_backwards to
	find a suitable prev_stop when we find ourselves before
	base_level_stop.
	(reseat): Don't look for prev_stop, as that could mean a very long
	run.
	<cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
	<cached_disp_overlay_modiff>: Cache for last found display string
	position.
	(compute_display_string_pos): Return the cached position if asked
	about the same buffer in the same area of character positions, and
	the buffer wasn't changed since the time the display string
	position was cached.

2011-07-22  Eli Zaretskii  <eliz@gnu.org>

	* xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
	is an integer, which is important for empty lines.  (Bug#9149)

2011-07-22  Chong Yidong  <cyd@stupidchicken.com>

	* frame.c (Fmodify_frame_parameters): In tty case, update the
	default face if necessary (Bug#4238).

2011-07-21  Chong Yidong  <cyd@stupidchicken.com>

	* editfns.c (Fstring_to_char): No need to explain what a character
	is in the docstring (Bug#6576).

2011-07-20  Lars Magne Ingebrigtsen  <larsi@gnus.org>

	* xml.c (parse_region): Make sure we always return a tree.

2011-07-20  HAMANO Kiyoto  <khiker.mail@gmail.com>

	* xml.c (make_dom): Return comments, too.

2011-07-19  Paul Eggert  <eggert@cs.ucla.edu>

	Port to OpenBSD.
	See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
	and the surrounding thread.
	* minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
	rather than fgets, and retry after EINTR.  Otherwise, 'emacs
	--batch -f byte-compile-file' fails on OpenBSD if an inactivity
	timer goes off.
	* s/openbsd.h (BROKEN_SIGIO): Define.

	This fixes some race conditions on the permissions of any newly
	created file.

	* alloc.c (valid_pointer_p): Use pipe, not open.
	This fixes some permissions issues when debugging.

	* fileio.c (Fcopy_file): Adjust mode if fchown fails.  (Bug#9002)
	If fchown fails to set both uid and gid, try to set just gid,
	as that is sometimes allowed.  Adjust the file's mode to eliminate

	Recent glibc declares fchown with __attribute__((warn_unused_result)),
	and without this change, GCC might complain about discarding
	fchown's return value.

2011-07-16  Juanma Barranquero  <lekktu@gmail.com>

	* bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.

	of the confusion.

	* eval.c (struct backtrace): Simplify and port the data structure.
	Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
	signed bit field, as this assumption is not portable and it makes
	Emacs crash when compiled with Sun C 5.8 on sparc.  Do not use
	"char debug_on_exit : 1" as this is not portable either; instead,
	use the portable "unsigned int debug_on_exit : 1".  Remove unused

	(read_list): Don't assume file position fits in int.
	(read_escape): Check for hex character overflow.

2011-06-22  Leo Liu  <sdl.web@gmail.com>

	* minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
	Move to minibuffer.el.

2011-06-22  Paul Eggert  <eggert@cs.ucla.edu>

	Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
	The following patches are for when GLYPH_DEBUG && !XASSERT.
	* dispextern.h (trace_redisplay_p, dump_glyph_string):
	* dispnew.c (flush_stdout):
	* xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
	Mark as externally visible.
	* dispnew.c (check_window_matrix_pointers): Now static.
	* dispnew.c (window_to_frame_vpos):
	* xfns.c (unwind_create_frame):
	* xterm.c (x_check_font): Remove unused local.
	* scroll.c (CHECK_BOUNDS):
	* xfaces.c (cache_fache): Rename local to avoid shadowing.
	* xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
	* xdisp.c (check_window_end): Now a no-op if !XASSERTS.
	(debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
	(debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
	Now static.
	(debug_method_add): Use va_list and vsprintf rather than relying
	on undefined behavior with wrong number of arguments.
	(dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
	Don't assume ptrdiff_t and EMACS_INT are the same width as int.
	In this code, it's OK to assume C99 behavior for ptrdiff_t formats
	since we're not interested in debugging glyphs with old libraries.
	* xfaces.c (cache_face): Move debugging code earlier; this pacifies
	GCC 4.6.0's static checking.

2011-06-22  Paul Eggert  <eggert@cs.ucla.edu>

	Integer overflow and signedness fixes (Bug#8873).
	A few related buffer overrun fixes, too.

	(x_session_initialize): Do not assume string length fits in int.

	* xsettings.c (apply_xft_settings): Fix potential buffer overrun.
	This is unlikely, but can occur if DPI is outlandish.

	* xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
	* xselect.c (Fx_get_atom_name): Avoid need for strlen.

	* xrdb.c: Don't assume strlen fits in int; avoid some strlens.
	* xrdb.c (magic_file_p, search_magic_path):
	Omit last arg SUFFIX; it was always 0.  All callers changed.
	(magic_file_p): Use ptrdiff_t, not int.  Check for size overflow.

	* xfont.c (xfont_match): Avoid need for strlen.

	* xfns.c: Don't assume strlen fits in int.
	(xic_create_fontsetname, x_window): Use ptrdiff_t, not int.

	* xdisp.c (message_log_check_duplicate): Return intmax_t,
	not unsigned long, as we prefer signed integers.  All callers changed.
	Detect integer overflow in repeat count.
	(message_dolog): Don't assume print length fits in 39 bytes.
	(display_mode_element): Don't assume strlen fits in int.

	* termcap.c: Don't assume sizes fit in int and never overflow.
	(struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
	(gobble_line): Check for size-calculation overflow.

	* minibuf.c (Fread_buffer):

	Don't assume string length fits in int.

	* keyboard.c (parse_tool_bar_item):
	* gtkutil.c (style_changed_cb): Avoid need for strlen.

	* font.c: Don't assume string length fits in int.
	(font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
	Use ptrdiff_t, not int.
	(font_intern_prop): Don't assume string length fits in int.
	Don't assume integer property fits in fixnum.
	* font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.

	* filelock.c: Fix some buffer overrun and integer overflow issues.
	(get_boot_time): Don't assume gzip command string fits in 100 bytes.
	Reformulate so as not to need the command string.
	Invoke gzip -cd rather than gunzip, as it's more portable.
	(lock_info_type, lock_file_1, lock_file):
	Don't assume pid_t and time_t fit in unsigned long.
	(LOCK_PID_MAX): Remove; we now use more-reliable bounds.
	(current_lock_owner): Prefer signed type for sizes.
	Use memcpy, not strncpy, where memcpy is what is really wanted.
	Don't assume (via atoi) that time_t and pid_t fit in int.
	Check for time_t and/or pid_t out of range, e.g., via a network share.
	Don't alloca where an auto var works fine.

	* fileio.c: Fix some integer overflow issues.
	(file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
	Don't assume string length fits in int.
	(directory_file_name): Don't assume string length fits in long.
	(make_temp_name): Don't assume pid fits in int, or that its print
	length is less than 20.

	* data.c (Fsubr_name): Rewrite to avoid a strlen call.

	* coding.c (make_subsidiaries): Don't assume string length fits in int.

	* callproc.c (child_setup): Rewrite to avoid two strlen calls.

	* process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
	We prefer signed integers, even for size calculations.

	* emacs.c: Don't assume string length fits in 'int'.
	(DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
	(main): Don't invoke strlen when not needed.

	* dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
	(XD_DEBUG_MESSAGE): Don't waste a byte.

	* callproc.c (getenv_internal_1, getenv_internal)
	(Fgetenv_internal):
	* buffer.c (init_buffer): Don't assume string length fits in 'int'.

	* lread.c (invalid_syntax): Omit length argument.
	All uses changed.  This doesn't fix a bug, but it simplifies the
	code away from its former Hollerith-constant appearance, and it's
	one less 'int' to worry about when looking at integer-overflow issues.
	(string_to_number): Simplify 2011-04-26 change by invoking xsignal1.

	* lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
	This didn't break anything, but it didn't help either.
	It's confusing to put a bogus integer in a place where the actual
	value does not matter.
	(LIST_END_P): Remove unused macro and its bogus comment.
	(make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.

	* lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
	This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
	implementation.
	(struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
	We prefer signed types, and the value cannot exceed the EMACS_INT
	range anyway (because otherwise the length would not be representable).
	(XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
	not EMACS_UINT and EMACS_INT, when converting pointer to integer.
	This avoids a GCC warning when WIDE_EMACS_INT.

	* indent.c (sane_tab_width): New function.
	(current_column, scan_for_column, Findent_to, position_indentation)
	(compute_motion): Use it.  This is just for clarity.
	(Fcompute_motion): Don't assume hscroll and tab offset fit in int.

	* image.c (xbm_image_p): Don't assume stated width, height fit in int.

	* lisp.h (lint_assume): New macro.
	* composite.c (composition_gstring_put_cache):
	* ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.

	* editfns.c, insdel.c:
	Omit unnecessary forward decls, to simplify future changes.

	* ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.

	* font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.

	* fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
	Use much-faster test for byte-length change.
	Don't assume string byte-length fits in 'int'.
	Check that character arg fits in 'int'.
	(mapcar1): Declare byte as byte, for clarity.

	* alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.

	* fns.c (concat): Catch string overflow earlier.
	Do not rely on integer wraparound.

	* dispextern.h (struct it.overlay_strings_charpos)
	(struct it.selective): Now EMACS_INT, not int.
	* xdisp.c (forward_to_next_line_start)
	(back_to_previous_visible_line_start)
	(reseat_at_next_visible_line_start, next_element_from_buffer):
	Don't arbitrarily truncate the value of 'selective' to int.

	* xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.

	* composite.c: Don't truncate sizes to 'int'.
	(composition_gstring_p, composition_reseat_it)
	(composition_adjust_point): Use EMACS_INT, not int.
	(get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
	not EMACS_UINT, for indexes.

	* category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.

	* buffer.c: Include <verify.h>.
	(struct sortvec.priority, struct sortstr.priority):
	Now EMACS_INT, not int.
	(compare_overlays, cmp_for_strings): Avoid subtraction overflow.
	(struct sortstr.size, record_overlay_string)
	(struct sortstrlist.size, struct sortlist.used):
	Don't truncate size to int.
	(record_overlay_string): Check for size-calculation overflow.
	(init_buffer_once): Check at compile-time, not run-time.

2011-06-22  Jim Meyering  <meyering@redhat.com>

	Don't leak an XBM-image-sized buffer
	* image.c (xbm_load): Free the image buffer after using it.

2011-06-21  Paul Eggert  <eggert@cs.ucla.edu>

	Port to Sun C.
	* composite.c (find_automatic_composition): Omit needless 'return 0;'
	that Sun C diagnosed.
	* fns.c (secure_hash): Fix pointer signedness issue.
	* intervals.c (static_offset_intervals): New function.
	(offset_intervals): Use it.

2011-06-21  Leo Liu  <sdl.web@gmail.com>

	* deps.mk (fns.o):
	* makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
	sha512.h.

	* fns.c (secure_hash): Rename from crypto_hash_function and change
	the first arg to accept symbols.
	(Fsecure_hash): New primitive.
	(syms_of_fns): New symbols.

2011-06-20  Deniz Dogan  <deniz@dogan.se>

	* process.c (Fset_process_buffer): Clarify return value in
	docstring.

2011-06-18  Chong Yidong  <cyd@stupidchicken.com>

	* dispnew.c (add_window_display_history): Use BVAR.

	* xdisp.c (debug_method_add): Use BVAR.
	(check_window_end, dump_glyph_matrix, dump_glyph)
	(dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.

	* xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
	Likewise.

	* xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
	check till after the cache is created in init_frame_faces.

2011-06-17  Stefan Monnier  <monnier@iro.umontreal.ca>

	* fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.

2011-06-16  Paul Eggert  <eggert@cs.ucla.edu>

	* lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
	Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
	hosts with pre-C99 libraries, because pD is wrongly defined to "t".

	Improve buffer-overflow checking (Bug#8873).
	* fileio.c (Finsert_file_contents):
	* insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
	Remove the old (too-loose) buffer overflow checks.
	They weren't needed, since make_gap checks for buffer overflow.
	* insdel.c (make_gap_larger): Catch buffer overflows that were missed.
	The old code merely checked for Emacs fixnum overflow, and relied
	on undefined (wraparound) behavior.  The new code avoids undefined
	behavior, and also checks for ptrdiff_t and/or size_t overflow.

	* editfns.c (Finsert_char): Don't dump core with very negative counts.
	Tune.  Don't use wider integers than needed.  Don't use alloca.
	Use a bigger 'string' buffer.  Rewrite to avoid 'n > 0' test.

	* insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.

	* insdel.c, lisp.h (buffer_overflow): New function.
	(insert_from_buffer_1, replace_range, replace_range_2):
	* insdel.c (make_gap_larger):
	* editfns.c (Finsert_char):
	* fileio.c (Finsert_file_contents): Use it, to normalize wording.

	* buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.

2011-06-15  Paul Eggert  <eggert@cs.ucla.edu>

	Integer overflow and signedness fixes (Bug#8873).

	* ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
	(GET_CCL_RANGE, IN_INT_RANGE): Use it.

	* fileio.c: Don't assume EMACS_INT fits in off_t.
	(emacs_lseek): New static function.
	(Finsert_file_contents, Fwrite_region): Use it.
	Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.

	* fns.c (Fload_average): Don't assume 100 * load average fits in int.

	* fns.c: Don't overflow int when computing a list length.
	* fns.c (QUIT_COUNT_HEURISTIC): New constant.
	(Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
	truncation on 64-bit hosts.  Check for QUIT every
	QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
	faster and is responsive enough.
	(Flength): Report an error instead of overflowing an integer.
	(Fsafe_length): Return a float if the value is not representable
	as a fixnum.  This shouldn't happen except in contrived situations.
	(Fnthcdr, Fsort): Don't assume list length fits in int.
	(Fcopy_sequence): Don't assume vector length fits in int.

	* alloc.c: Check that resized vectors' lengths fit in fixnums.
	(header_size, word_size): New constants.
	(allocate_vectorlike): Don't check size overflow here.
	(allocate_vector): Check it here instead, since this is the only
	caller of allocate_vectorlike that could cause overflow.
	Check that the new vector's length is representable as a fixnum.

	* fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
	The previous code was bogus.  For example, next_almost_prime (32)
	returned 39, which is undesirable as it is a multiple of 3; and
	next_almost_prime (24) returned 25, which is a multiple of 5 so
	why was the code bothering to check for multiples of 7?

	* bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.

	* eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.

	Variadic C functions now count arguments with ptrdiff_t.
	This partly undoes my 2011-03-30 change, which replaced int with size_t.
	Back then I didn't know that the Emacs coding style prefers signed int.
	Also, in the meantime I found a few more instances where arguments
	were being counted with int, which may truncate counts on 64-bit
	machines, or EMACS_INT, which may be unnecessarily wide.
	* lisp.h (struct Lisp_Subr.function.aMANY)
	(DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
	Arg counts are now ptrdiff_t, not size_t.
	All variadic functions and their callers changed accordingly.
	(struct gcpro.nvars): Now size_t, not size_t.  All uses changed.
	* bytecode.c (exec_byte_code): Check maxdepth for overflow,
	to avoid potential buffer overrun.  Don't assume arg counts fit in 'int'.
	* callint.c (Fcall_interactively): Check arg count for overflow,
	to avoid potential buffer overrun.  Use signed char, not 'int',
	for 'varies' array, so that we needn't bother to check its size
	calculation for overflow.
	* editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
	* eval.c (apply_lambda):
	* fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
	(struct textprop_rec.argnum): Now ptrdiff_t, not int.  All uses changed.
	(mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.

	* callint.c (Fcall_interactively): Don't use index var as event count.

	* vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
	* mem-limits.h (SIZE): Remove; no longer used.

	* xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.

	Remove unnecessary casts.
	* xterm.c (x_term_init):
	* xfns.c (x_set_border_pixel):
	* widget.c (create_frame_gcs): Remove casts to unsigned long etc.
	These aren't needed now that we assume ANSI C.

	* sound.c (Fplay_sound_internal): Remove cast to unsigned long.
	It's more likely to cause problems (due to unsigned overflow)
	than to cure them.

	* dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.

	* unexelf.c (unexec): Don't assume BSS addr fits in unsigned.

	* xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.

	* keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.

	* lisp.h (CHAR_TABLE_SET): Omit now-redundant test.

	* lread.c (Fload): Don't compare a possibly-garbage time_t value.

	GLYPH_CODE_FACE returns EMACS_INT, not int.
	* dispextern.h (merge_faces):
	* xfaces.c (merge_faces):
	* xdisp.c (get_next_display_element, next_element_from_display_vector):
	Don't assume EMACS_INT fits in int.

	* character.h (CHAR_VALID_P): Remove unused parameter.
	* fontset.c, lisp.h, xdisp.c: All uses changed.

	* editfns.c (Ftranslate_region_internal): Omit redundant test.

	* fns.c (concat): Minor tuning based on overflow analysis.
	This doesn't fix any bugs.  Use int to hold character, instead
	of constantly refetching from Emacs object.  Use XFASTINT, not
	XINT, for value known to be a character.  Don't bother comparing
	a single byte to 0400, as it's always less.

	* floatfns.c (Fexpt):
	* fileio.c (make_temp_name): Omit unnecessary cast to unsigned.

	* editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
	for characters.

	* doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.

	* data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
	Without this fix, on a 64-bit host (aset S 0 4294967386) would
	incorrectly succeed when S was a string, because 4294967386 was
	truncated before it was used.

	* chartab.c (Fchar_table_range): Use CHARACTERP to check range.
	Otherwise, an out-of-range integer could cause undefined behavior
	on a 64-bit host.

	* composite.c: Use int, not EMACS_INT, for characters.
	(fill_gstring_body, composition_compute_stop_pos): Use int, not
	EMACS_INT, for values that are known to be in character range.
	This doesn't fix any bugs but is the usual style inside Emacs and
	may generate better code on 32-bit machines.

	Make sure a 64-bit char is never passed to ENCODE_CHAR.
	This is for reasons similar to the recent CHAR_STRING fix.
	* charset.c (Fencode_char): Check that character arg is actually
	a character.  Pass an int to ENCODE_CHAR.
	* charset.h (ENCODE_CHAR): Verify that the character argument is no
	wider than 'int', as a compile-time check to prevent future regressions
	in this area.

	* character.c (char_string): Remove unnecessary casts.

	Make sure a 64-bit char is never passed to CHAR_STRING.
	Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
	by silently ignoring the top 32 bits, allowing some values
	that were far too large to be valid characters.
	* character.h: Include <verify.h>.
	(CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
	arguments are no wider than unsigned, as a compile-time check
	to prevent future regressions in this area.
	* data.c (Faset):
	* editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
	(Fsubst_char_in_region):
	* fns.c (concat):
	* xdisp.c (decode_mode_spec_coding):
	Adjust to CHAR_STRING's new requirement.
	* editfns.c (Finsert_char, Fsubst_char_in_region):
	* fns.c (concat): Check that character args are actually
	characters.  Without this test, these functions did the wrong
	thing with wildly out-of-range values on 64-bit hosts.

	Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
	These casts should not be needed on 32-bit hosts, either.
	* keyboard.c (read_char):
	* lread.c (Fload): Remove casts to unsigned.

	* lisp.h (UNSIGNED_CMP): New macro.
	This fixes comparison bugs on 64-bit hosts.
	(ASCII_CHAR_P): Use it.
	* casefiddle.c (casify_object):
	* character.h (ASCII_BYTE_P, CHAR_VALID_P)
	(SINGLE_BYTE_CHAR_P, CHAR_STRING):
	* composite.h (COMPOSITION_ENCODE_RULE_VALID):
	* dispextern.h (FACE_FROM_ID):
	* keyboard.c (read_char): Use UNSIGNED_CMP.

	* xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
	not to EMACS_INT, to avoid GCC warning.

	* xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.

	* buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
	The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
	isn't needed on 32-bit machines.

	* buffer.c (Fgenerate_new_buffer_name):
	Use EMACS_INT for count, not int.
	(advance_to_char_boundary): Return EMACS_INT, not int.

	* data.c (Qcompiled_function): Now static.

	* window.c (window_body_lines): Now static.

	* image.c (gif_load): Rename local to avoid shadowing.

	some instances we weren't catching before.  Also, it catches
	size_t overflow on (unusual) hosts where SIZE_MAX <= min

	and ptrdiff_t and EMACS_INT are both 64 bits.

	All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.

	definitions.
	(bidi_explicit_dir_char): Lookup character type in bidi_type_table,
	instead of using explicit *_CHAR codes.
	(bidi_resolve_explicit, bidi_resolve_weak):
	Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
	bidirectional text is supported only in multibyte buffers.
	(bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
	it to initialize the frame_window_p member of struct bidi_it.
	(bidi_cache_iterator_state, bidi_resolve_explicit_1)

	(bidi_level_of_next_char, bidi_move_to_visually_next): Abort if
	bidi_it->nchars is non-positive.
	(bidi_level_of_next_char): Don't try to lookup the cache for the

	handle_display_spec instead of single_display_spec_intangible_p.
	Accept 3 additional arguments needed by handle_display_spec.
	This fixes incorrect cursor motion across display property with complex
	values: lists, `(when COND...)' forms, etc.
	(single_display_spec_string_p): Support property values that are
	lists with the argument STRING its top-level element.
	(display_prop_string_p): Fix the condition for processing a
	property that is a list to be consistent with handle_display_spec.
	(handle_display_spec): New function, refactored from the
	last portion of handle_display_prop.
	(compute_display_string_pos): Accept additional argument

	value of a `display' property is a "replacing spec".
	(handle_single_display_spec): Accept 2 additional arguments BUFPOS
	and FRAME_WINDOW_P.  If IT is NULL, don't set up the iterator from
	the display property, but just return a value indicating whether
	the display property will replace the characters it covers.
	(Fcurrent_bidi_paragraph_direction): Initialize the nchars and
	frame_window_p members of struct bidi_it.
	(compute_display_string_pos, compute_display_string_end):
	New functions.
	(push_it): Accept second argument POSITION, where pop_it should

	* lisp.h: Change signatures accordingly.
	* alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
	All callers changed.  (Bug#8762)

	* gnutls.c: Use Emacs's memory allocators.
	Without this change, the gnutls library would invoke malloc etc.
	directly, which causes problems on non-SYNC_INPUT hosts, and which
	runs afoul of improving memory_full behavior.  (Bug#8761)
	(fn_gnutls_global_set_mem_functions): New macro or function pointer.
	(emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
	xfree instead of the default malloc, realloc, free.
	(Fgnutls_boot): No need to check for memory allocation failure,
	since xmalloc does that for us.

	Remove arbitrary limit of 2**31 entries in hash tables.  (Bug#8771)
	* category.c (hash_get_category_set):
	* ccl.c (ccl_driver):
	* charset.c (Fdefine_charset_internal):
	* charset.h (struct charset.hash_index):

	(cmpfn_equal, cmpfn_user_defined, hashfn_eq, hashfn_eql)
	(hashfn_equal, hashfn_user_defined, make_hash_table)
	(maybe_resize_hash_table, hash_lookup, hash_put)
	(hash_remove_from_table, hash_clear, sweep_weak_table, SXHASH_COMBINE)
	(sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
	(Fsxhash, Fgethash, Fputhash, Fmaphash):
	* image.c (make_image, search_image_cache, lookup_image)
	(xpm_put_color_table_h):
	* lisp.h (struct Lisp_Hash_Table):
	* minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
	* print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
	for hashes and hash indexes, instead of 'unsigned' and 'int'.
	* alloc.c (allocate_vectorlike):
	Check for overflow in vector size calculations.
	* ccl.c (ccl_driver):
	Check for overflow when converting EMACS_INT to int.
	* fns.c, image.c: Remove unnecessary static decls that would otherwise
	need to be updated by these changes.
	* fns.c (make_hash_table, maybe_resize_hash_table):
	Check for integer overflow with large hash tables.
	(make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
	Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
	(SXHASH_REDUCE): New macro.
	(sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
	Use it instead of discarding useful hash info with large hash values.
	(sxhash_float): New function.
	(sxhash): Use it.  No more need for "& INTMASK" due to above changes.
	* lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
	(MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
	Rewrite to use FIXNUM_BITS, as this simplifies things.
	(next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
	Adjust signatures to match updated version of code.
	(consing_since_gc): Now EMACS_INT, since a single hash table can
	use more than INT_MAX bytes.

2011-06-01  Dan Nicolaescu  <dann@ics.uci.edu>

	Make it possible to build with GCC-4.6+ -O2 -flto.

	* emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.

2011-06-01  Stefan Monnier  <monnier@iro.umontreal.ca>

	* minibuf.c (get_minibuffer, read_minibuf_unwind):
	Call minibuffer-inactive-mode.

2011-05-31  Juanma Barranquero  <lekktu@gmail.com>

	Update dependencies.

2011-05-31  Dan Nicolaescu  <dann@ics.uci.edu>

	* data.c (init_data): Remove code for UTS, this system is not
	supported anymore.

2011-05-31  Dan Nicolaescu  <dann@ics.uci.edu>

	Don't force ./temacs to start in terminal mode.

	* frame.c (make_initial_frame): Initialize faces in all cases, not
	only when CANNOT_DUMP is defined.
	* dispnew.c (init_display): Remove CANNOT_DUMP condition.

2011-05-31  Dan Nicolaescu  <dann@ics.uci.edu>

	* dispnew.c (add_window_display_history): Use const for the string
	pointer.  Remove declaration, not needed.

2011-05-31  Paul Eggert  <eggert@cs.ucla.edu>

	Use 'inline', not 'INLINE'.
	<http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
	* alloc.c, fontset.c (INLINE): Remove.
	* alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
	* intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
	* xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
	* gmalloc.c (register_heapinfo): Use inline unconditionally.
	* lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.

2011-05-31  Dan Nicolaescu  <dann@ics.uci.edu>

	Make it possible to run ./temacs.

	* callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
	syms_of_callproc does the same thing.  Remove test for
	"initialized", do it in the caller.
	* emacs.c (main): Avoid calling set_initial_environment when dumping.

2011-05-31  Stefan Monnier  <monnier@iro.umontreal.ca>

	* minibuf.c (Finternal_complete_buffer): Return `category' metadata.
	(read_minibuf): Use get_minibuffer.
	(syms_of_minibuf): Use DEFSYM.
	(Qmetadata): New var.
	* data.c (Qbuffer): Don't make it static.
	(syms_of_data): Use DEFSYM.

2011-05-31  Paul Eggert  <eggert@cs.ucla.edu>

	* ccl.c (CCL_CODE_RANGE): Allow negative numbers.  (Bug#8751)
	(CCL_CODE_MIN): New macro.

2011-05-30  Paul Eggert  <eggert@cs.ucla.edu>

	* alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.

	* eval.c (Qdebug): Now static.
	* lisp.h (Qdebug): Remove decl.  This reverts a part of the
	2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
	2011-04-14T06:48:41Z!eggert@cs.ucla.edu.

2011-05-29  Chong Yidong  <cyd@stupidchicken.com>

	* image.c: Various fixes to ImageMagick code comments.
	(Fimagemagick_types): Doc fix.

	* xselect.c (converted_selections, conversion_fail_tag): Now static.

	* emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
	(x_clipboard_manager_save_all): Move extern decl to ...

2011-05-29  Chong Yidong  <cyd@stupidchicken.com>

	* xselect.c (x_clipboard_manager_save_frame)
	(x_clipboard_manager_save_all): New functions.
	(Fx_clipboard_manager_save): Lisp function deleted.

2011-05-28  William Xu  <william.xwl@gmail.com>

	* nsterm.m (ns_term_shutdown): Synchronize user defaults before
	exiting (Bug#8239).

2011-05-28  Jim Meyering  <meyering@redhat.com>

	Avoid a sign-extension bug in crypto_hash_function.
	* fns.c (to_uchar): Define.
	(crypto_hash_function): Use it to convert some newly-signed
	variables to unsigned, to avoid sign-extension bugs.  For example,
	without this change, (md5 "truc") would evaluate to
	45723a2aff78ff4fff7fff1114760e62 rather than the expected
	45723a2af3788c4ff17f8d1114760e62.  Reported by Antoine Levitt in
	https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.

2011-05-27  Paul Eggert  <eggert@cs.ucla.edu>

	Integer overflow fixes.

	* dbusbind.c: Serial number integer overflow fixes.
	(CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
	(Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
	to hold a serial number that is too large for a fixnum.
	(Fdbus_method_return_internal, Fdbus_method_error_internal):
	Check for serial numbers out of range.  Decode any serial number
	that was so large that it became a float.  (Bug#8722)

	* dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
	(Fdbus_call_method, Fdbus_call_method_asynchronously):
	Use XFASTINT rather than XUINT when numbers are nonnegative.
	(xd_append_arg, Fdbus_method_return_internal):
	(Fdbus_method_error_internal): Likewise.  Also, for unsigned
	arguments, check that Lisp number is nonnegative, rather than
	silently wrapping negative numbers around.  (Bug#8722)
	(xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
	(Bug#8722)

	* data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.

	* ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.

	ccl: add integer overflow checks
	* ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
	(IN_INT_RANGE): New macros.
	(ccl_driver): Use them to check for integer overflow when
	decoding a CCL program.  Many of the new checks are whether XINT (x)
	fits in int; it doesn't always, on 64-bit hosts.  The new version
	doesn't catch all possible integer overflows, but it's an
	improvement.  (Bug#8719)

	* alloc.c (make_event_array): Use XINT, not XUINT.
	There's no need for unsigned here.

	* mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
	This follows up to the 2011-05-06 change that substituted uintptr_t
	for EMACS_INT.  This case wasn't caught back then.

	Rework Fformat to avoid integer overflow issues.
	* editfns.c: Include <float.h> unconditionally, as it's everywhere
	now (part of C89).  Include <verify.h>.
	(MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
	(pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
	(Fformat): Avoid the prepass trying to compute sizes; it was only
	approximate and thus did not catch overflow reliably.  Instead, walk
	through the format just once, formatting and computing sizes as we go,
	checking for integer overflow at every step, and allocating a larger
	buffer as needed.  Keep track separately whether the format is
	multibyte.  Keep only the most-recently calculated precision, rather
	than them all.  Record whether each argument has been converted to
	string.  Use EMACS_INT, not int, for byte and char and arg counts.
	Support field widths and precisions larger than INT_MAX.  Avoid
	sprintf's undefined behavior with conversion specifications such as %#d
	and %.0c.  Fix bug with strchr succeeding on '\0' when looking for
	flags.  Fix bug with (format "%c" 256.0).  Avoid integer overflow when
	formatting out-of-range floating point numbers with int
	formats.  (Bug#8668)

	* lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.

	* data.c: Avoid integer truncation in expressions involving floats.
	* data.c: Include <intprops.h>.
	(arith_driver): When there's an integer overflow in an expression
	involving floating point, convert the integers to floating point
	so that the resulting value does not suffer from catastrophic
	integer truncation.  For example, on a 64-bit host (* 4
	most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
	Do not rely on undefined behavior after integer overflow.

	merge count_size_as_multibyte, parse_str_to_multibyte
	* character.c, character.h (count_size_as_multibyte):
	Rename from parse_str_to_multibyte; all uses changed.
	Check for integer overflow.
	* insdel.c, lisp.h (count_size_as_multibyte): Remove,
	since it's now a duplicate of the other.  This is more of
	a character than a buffer op, so better that it's in character.c.
	* fns.c, print.c: Adjust to above changes.

2011-05-27  Stefan Monnier  <monnier@iro.umontreal.ca>

	* xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.

2011-05-27  Paul Eggert  <eggert@cs.ucla.edu>

	* xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
	(x_handle_selection_request, frame_for_x_selection): Remove unused vars.
	(x_clipboard_manager_save): Now static.
	(Fx_clipboard_manager_save): Rename local to avoid shadowing.

	* fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
	(crypto_hash_function): Now static.
	Fix pointer signedness problems.  Avoid unnecessary initializations.

	New arg, specifying work frame.  Use terminal-local Vselection_alist.
	(some_frame_on_display): Delete unused function.
	(Fx_own_selection_internal, Fx_get_selection_internal)
	(Fx_disown_selection_internal, Fx_selection_owner_p)
	(Fx_selection_exists_p): New optional frame arg.
	(frame_for_x_selection, Fx_clipboard_manager_save): New functions.
	(x_handle_selection_clear): Don't treat other terminals with the
	same keyboard specially.  Use the terminal-local Vselection_alist.
	(x_clear_frame_selections): Use Frun_hook_with_args.

	* xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.

	* xterm.h: Add support for those atoms.

2011-05-26  Chong Yidong  <cyd@stupidchicken.com>

	(converted_selections, conversion_fail_tag): New global variables.
	(x_selection_request_lisp_error): Free the above.

	(x_reply_selection_request): Args changed; handle arbitrary array
	of converted selections stored in converted_selections.
	Separate the XChangeProperty and SelectionNotify steps.
	(x_handle_selection_request): Rewrite to handle MULTIPLE target.
	(x_convert_selection): New function.
	(x_handle_selection_event): Simplify.
	(x_get_foreign_selection): Don't ignore incoming requests while
	waiting for an answer; this will fail when we implement
	SAVE_TARGETS, and seems unnecessary anyway.
	(selection_data_to_lisp_data): Recognize ATOM_PAIR type.
	(Vx_sent_selection_functions): Doc fix.

2011-05-26  Leo Liu  <sdl.web@gmail.com>

	* dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.

	* dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
	for fringe update if it has periodic bitmap.
	(row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
	and fringe_bitmap_periodic_p.

	* fringe.c (get_fringe_bitmap_data): New function.
	(draw_fringe_bitmap_1, update_window_fringes): Use it.
	(update_window_fringes): Record periodicity of fringe bitmap in glyph
	row.  Mark glyph row for fringe update if periodicity changed.

	* xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
	for fringe update unless it has periodic bitmap.

2011-05-25  Kenichi Handa  <handa@m17n.org>

	* xdisp.c (get_next_display_element): Set correct it->face_id for
	a static composition.

2011-05-24  Leo Liu  <sdl.web@gmail.com>

	* deps.mk (fns.o):
	* makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.

	(Fmd5): Use crypto_hash_function.
	(syms_of_fns): Add Ssha1.

2011-05-22  Paul Eggert  <eggert@cs.ucla.edu>

	* gnutls.c: Remove unused macros.
	(fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
	(fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
	Remove macros that are defined and never used.
	Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).

2011-05-22  Chong Yidong  <cyd@stupidchicken.com>

	* xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
	(Fx_get_selection_internal): Minor cleanup.
	(Fx_own_selection_internal): Rename arguments for consistency with
	select.el.

2011-05-22  Paul Eggert  <eggert@cs.ucla.edu>

	* xselect.c (QSAVE_TARGETS): New static var, to fix build failure.

2011-05-22  Chong Yidong  <cyd@stupidchicken.com>

	* xselect.c (syms_of_xselect): Include character.h; use DEFSYM.

2011-05-21  YAMAMOTO Mitsuharu  <mituharu@math.s.chiba-u.ac.jp>

	* dispnew.c (scrolling_window): Don't exclude the case that the
	last enabled row in the desired matrix touches the bottom boundary.

2011-05-21  Glenn Morris  <rgm@gnu.org>

	* Makefile.in ($(etc)/DOC): Make second command line even shorter.
	(SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
	and add some more files.

2011-05-20  Eli Zaretskii  <eliz@gnu.org>

	* callproc.c (Fcall_process) [MSDOS]: Fix arguments to
	report_file_error introduced by the change from 2011-05-07.

2011-05-20  Paul Eggert  <eggert@cs.ucla.edu>

	* systime.h (Time): Define only if emacs is defined.
	This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
	where the include path doesn't have X11/X.h by default.  See
	<http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.

2011-05-20 Kenichi Handa  <handa@m17n.org>

	* composite.c (find_automatic_composition): Fix previous change.

2011-05-20  Glenn Morris  <rgm@gnu.org>

	* lisp.mk: New file, split from Makefile.in.
	* Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
	(shortlisp): Remove.
	($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.

2011-05-19  Glenn Morris  <rgm@gnu.org>

	* Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
	(REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
	(BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
	(lisp): Set the order to that of loadup.el.
	(shortlisp): Make it a copy of $lisp.
	(SOME_MACHINE_LISP): Remove.
	($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.

2011-05-18  Kenichi Handa  <handa@m17n.org>

	* composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
	(BACKWARD_CHAR): Wrap the arg STOP by parenthesis.

2011-05-18  Christoph Scholtes  <cschol2112@googlemail.com>

	* menu.c: Include limits.h (fixes the MS-Windows build broken by
	2011-06-18T18:49:19Z!cyd@stupidchicken.com).

2011-05-18  Paul Eggert  <eggert@cs.ucla.edu>

	Fix some integer overflow issues, such as string length overflow.

	* insdel.c (count_size_as_multibyte): Check for string overflow.

	* character.c (lisp_string_width): Check for string overflow.
	Use EMACS_INT, not int, for string indexes and lengths; in
	particular, 2nd arg is now EMACS_INT, not int.  Do not crash if
	the resulting string length overflows an EMACS_INT; instead,
	report a string overflow if no precision given.  When checking for
	precision exhaustion, use a check that cannot possibly have
	integer overflow.  (Bug#8675)
	* character.h (lisp_string_width): Adjust to new signature.

	* alloc.c (string_overflow): New function.
	(Fmake_string): Use it.  This doesn't change behavior, but saves
	a few bytes and will simplify future changes.
	* character.c (string_escape_byte8): Likewise.
	* lisp.h (string_overflow): New decl.

	Fixups, following up to the user-interface timestamp change.
	* nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
	for UI timestamps, instead of unsigned long.
	* msdos.c (mouse_get_pos): Likewise.
	* w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
	* w32gui.h (Time): Define by including "systime.h" rather than by
	declaring it ourselves.  (Bug#8664)

	* dispextern.h (struct image): Don't assume time_t <= unsigned long.
	* image.c (clear_image_cache): Likewise.

	* term.c (term_mouse_position): Don't assume time_t wraparound.

	Be more systematic about user-interface timestamps.
	Before, the code sometimes used 'Time', sometimes 'unsigned long',
	and sometimes 'EMACS_UINT', to represent these timestamps.
	This change causes it to use 'Time' uniformly, as that's what X uses.
	This makes the code easier to follow, and makes it easier to catch
	integer overflow bugs such as Bug#8664.
	* frame.c (Fmouse_position, Fmouse_pixel_position):
	Use Time, not unsigned long, for user-interface timestamps.
	* keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
	(button_down_time, make_lispy_position, make_lispy_movement): Likewise.
	* keyboard.h (last_event_timestamp): Likewise.
	* menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
	* menu.h (xmenu_show): Likewise.
	* term.c (term_mouse_position): Likewise.
	* termhooks.h (struct input_event.timestamp): Likewise.
	(struct terminal.mouse_position_hook): Likewise.
	* xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
	* xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
	* systime.h (Time): New decl.  Pull it in from <X11/X.h> if
	HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
	what it was before.
	* menu.h, termhooks.h: Include "systime.h", for Time.

	* keyboard.c (make_lispy_event): Fix problem in integer overflow.
	Don't assume that the difference between two unsigned long values
	can fit into an integer.  At this point, we know button_down_time
	<= event->timestamp, so the difference must be nonnegative, so
	there's no need to cast the result if double-click-time is
	nonnegative, as it should be; check that it's nonnegative, just in
	case.  This bug is triggered when events are more than 2**31 ms
	apart (about 25 days).  (Bug#8664)

	* xselect.c (last_event_timestamp): Remove duplicate decl.
	(x_own_selection): Remove needless cast to unsigned long.

	* xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
	that always fit in int.  Use a sentinel instead of a counter, to
	avoid a temp and to allay GCC's concerns about possible int overflow.
	* frame.h (struct frame): Use int for menu_bar_items_used
	instead of EMACS_INT, since it always fits in int.

	* menu.c (grow_menu_items): Check for int overflow.

	* xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.

	* xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
	Before, the code was not consistent.  These values cannot exceed
	2**31 - 1 so there's no need to make them unsigned.
	(x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
	(x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
	(x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
	as modifiers.
	* xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.

	* lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
	(XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
	Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
	presumably because the widths might not match.

	* window.c (size_window): Avoid needless test at loop start.

2011-05-18  Courtney Bane  <emacs-bugs-7626@cbane.org>  (tiny change)

	* term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).

2011-05-12  Drew Adams  <drew.adams@oracle.com>

	* textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).

2011-05-12  YAMAMOTO Mitsuharu  <mituharu@math.s.chiba-u.ac.jp>

	* w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
	`width' to `bar_area_x' and `bar_area_width', respectively.
	(x_scroll_run): Take account of fringe background extension.

	* xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
	Rename local vars `left' and `width' to `bar_area_x' and
	`bar_area_width', respectively.
	(x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
	background extension.

2011-05-10  Jim Meyering  <meyering@redhat.com>

	* xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".

2011-05-10  Juanma Barranquero  <lekktu@gmail.com>

	* image.c (Finit_image_library): Return t for built-in image types,
	like pbm and xbm.  (Bug#8640)

2011-05-09  Andreas Schwab  <schwab@linux-m68k.org>

	* w32menu.c (set_frame_menubar): Fix submenu allocation.

2011-05-07  Eli Zaretskii  <eliz@gnu.org>

	* w32console.c (Fset_screen_color): Doc fix.
	(Fget_screen_color): New function.
	(syms_of_ntterm): Defsubr it.

	* callproc.c (call_process_cleanup) [MSDOS]: Don't close and
	unlink the temporary file if Fcall_process didn't create it in the
	first place.
	(Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
	child process will be redirected to a file specified with `:file'.
	Don't try to re-open tempfile in that case, and set fd[0] to -1 as
	cue to call_process_cleanup not to close that handle.

2011-05-07  Ben Key  <bkey76@gmail.com>

	* makefile.w32-in: The bootstrap-temacs rule now makes use of
	one of two shell specific rules, either bootstrap-temacs-CMD or
	bootstrap-temacs-SH.  The bootstrap-temacs-SH rule is identical
	to the previous implementation of the bootstrap-temacs rule.
	The bootstrap-temacs-CMD rule is similar to the previous
	implementation of the bootstrap-temacs rule except that it
	makes use of the ESC_CFLAGS variable instead of the CFLAGS
	variable.

	These changes, along with some changes to nt/configure.bat,
	nt/gmake.defs, and nt/nmake.defs, are required to extend my
	earlier fix to add support for --cflags and --ldflags options
	that include quotes so that it works whether make uses cmd or
	sh as the shell.

2011-05-06  Michael Albinus  <michael.albinus@gmx.de>

	* dbusbind.c (QCdbus_type_unix_fd): Declare static.
	(xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
	is a constant.
	(Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
	a string.  Handle both cases.
	(Fdbus_call_method_asynchronously, Fdbus_register_signal)
	(Fdbus_register_method): Use Qinvalid_function.

2011-05-06  Juanma Barranquero  <lekktu@gmail.com>

	* makefile.w32-in: Update dependencies.
	(LISP_H): Add inttypes.h and stdin.h.
	(PROCESS_H): Add unistd.h.

2011-05-06  Eli Zaretskii  <eliz@gnu.org>

	* lread.c: Include limits.h (fixes the MS-Windows build broken by
	2011-05-06T07:13:19Z!eggert@cs.ucla.edu).

2011-05-06  Paul Eggert  <eggert@cs.ucla.edu>

	* image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.

	* term.c (vfatal): Remove stray call to va_end.
	It's not needed and the C Standard doesn't allow it here anyway.

	Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
	* eval.c (verror): doprnt a copy of ap, not the original.  (Bug#8545)

	* eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
	bytes.

	* term.c: Don't include <stdarg.h>, as <lisp.h> does that.

	* callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.

	* process.c (Fformat_network_address): Fix typo: args2 -> *args2.

	* xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).

	* coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).

	* charset.h (struct charset.code_space): Now has 15 elements, not 16.
	* charset.c (Fdefine_charset_internal): Don't initialize
	charset.code_space[15].  The value was garbage, on hosts with
	32-bit int (Bug#8600).

	* lread.c (read_integer): Be more consistent with string-to-number.
	Use string_to_number to do the actual conversion; this avoids
	rounding errors and fixes some other screwups.  Without this fix,
	for example, #x1fffffffffffffff was misread as -2305843009213693952.
	(digit_to_number): Move earlier, for benefit of read_integer.
	Return -1 if the digit is out of range for the base, -2 if it is
	not a digit in any supported base.  (Bug#8602)

	* doprnt.c (doprnt): Support arbitrary pI values, such as "I64".

	* dispnew.c (scrolling_window): Return 1 if we scrolled,
	to match comment at start of function.  This also removes a
	GCC warning about overflow in a 32+64-bit port.

	* lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.

	* dbusbind.c: Do not use XPNTR on a value that may be an integer.
	Reported by Stefan Monnier in
	<http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
	(xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
	Use SYMBOLP-guarded XSYMBOL, not XPNTR.

	* lisp.h (EMACS_INTPTR): Remove.  All uses changed to intptr_t.
	(EMACS_UINTPTR): Likewise, with uintptr_t.

	* lisp.h: Prefer 64-bit EMACS_INT if available.
	(EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
	on 32-bit hosts that have 64-bit int, so that they can access
	large files.
	However, temporarily disable this change unless the temporary
	symbol WIDE_EMACS_INT is defined.

	* lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.

	Prefer intptr_t/uintptr_t for integers the same widths as pointers.
	This removes an assumption that EMACS_INT and long are the same
	width as pointers.  The assumption is true for Emacs porting targets
	now, but we want to make other targets possible.
	* lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
	(EMACS_INTPTR, EMACS_UINTPTR): New macros.
	In the rest of the code, change types of integers that hold casted
	pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
	replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
	(XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
	(XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
	No need to cast type when ORing.
	(XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
	* alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
	* doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
	assume EMACS_INT is the same width as char *.
	* gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
	(xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
	Remove no-longer-needed casts.
	(xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
	(xg_tool_bar_help_callback, xg_make_tool_item):
	Use EMACS_INTPTR to hold an integer
	that will be cast to void *; this can avoid a GCC warning
	if EMACS_INT is not the same width as void *.
	* menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
	* xdisp.c (display_echo_area_1, resize_mini_window_1):
	(current_message_1, set_message_1):
	Use a local to convert to proper width without a cast.
	* xmenu.c (dialog_selection_callback): Likewise.

	* sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
	Also, don't assume VALBITS / RAND_BITS is less than 5,
	and don't rely on undefined behavior when shifting a 1 left into
	the sign bit.
	* lisp.h (get_random): Change signature to match.

	* lread.c (hash_string): Use size_t, not int, for hash computation.
	Normally we prefer signed values; but hashing is special, because
	it's better to use unsigned division on hash table sizes so that
	the remainder is nonnegative.  Also, size_t is the natural width
	for hashing into memory.  The previous code used 'int', which doesn't
	retain enough info to hash well into very large tables.
	(oblookup, oblookup_last_bucket_number, Funintern): Likewise.

	* dbusbind.c: Don't possibly lose pointer info when converting.
	(xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
	Use XPNTR rather than XHASH, so that the high-order bits of
	the pointer aren't lost when converting through void *.

	* eval.c (Fautoload): Don't double-shift a pointer.

	* fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.

2011-05-06  Juanma Barranquero  <lekktu@gmail.com>

	* gnutls.c (DEF_GNUTLS_FN):
	* image.c (DEF_IMGLIB_FN): Make function pointers static.

2011-05-05  Andreas Schwab  <schwab@linux-m68k.org>

	* lread.c (lisp_file_lexically_bound_p): Stop scanning at end
	marker.  (Bug#8610)

2011-05-05 Eli Zaretskii  <eliz@gnu.org>

	* w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
	New version that can reserve upto 2GB of heap space.

2011-05-05  Chong Yidong  <cyd@stupidchicken.com>

	* nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).

2011-05-05  Teodor Zlatanov  <tzz@lifelogs.com>

	* gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
	`gnutls_certificate_set_x509_key_file'.

2011-05-05  Juanma Barranquero  <lekktu@gmail.com>

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

2011-05-04  Juanma Barranquero  <lekktu@gmail.com>

	* gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
	* gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
	Remove unused parameter `fildes'.
	* process.c (read_process_output, send_process): Don't pass it.

2011-05-04  Juanma Barranquero  <lekktu@gmail.com>

	Fix previous change: the library cache is defined in w32.c.
	* image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
	(Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".

2011-05-04  Juanma Barranquero  <lekktu@gmail.com>

	Implement dynamic loading of GnuTLS on Windows.

	* gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
	(emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
	(emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
	Declare.

	* gnutls.c (Qgnutls_dll): Define.
	(DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
	(gnutls_*): Declare function pointers.
	(init_gnutls_functions): New function to initialize function pointers.
	(emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
	(emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
	(emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
	Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
	(emacs_gnutls_write, emacs_gnutls_read)
	(emacs_gnutls_handle_error, Fgnutls_error_fatalp)
	(Fgnutls_available_p): New function.
	(Fgnutls_boot): Call Fgnutls_available_p.  Use function pointers.
	(syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
	(syms_of_gnutls) <Sgnutls_available_p>: defsubr it.

	* image.c: Include w32.h.
	(Vimage_type_cache): Delete.
	(syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
	(CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
	(w32_delayed_load): Move to w32.c.

	* w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.

	* w32.c (QCloaded_from, Vlibrary_cache): Define.
	(w32_delayed_load): Move from image.c.  When loading a library, record
	its filename in the :loaded-from property of the library id.
	(globals_of_w32) <QCloaded_from, Vlibrary_cache>:
	Initialize and staticpro them.
	(emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.

	* process.c: Include lisp.h before w32.h, not after.
	(wait_reading_process_output): Call emacs_gnutls_record_check_pending
	instead of gnutls_record_check_pending.

	which is like wait_for_termination, but allows keyboard
	interruptions.

	* callproc.c (Fcall_process): Add (:file "file") as an option for

2011-04-30  Eli Zaretskii  <eliz@gnu.org>

	* dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
	rather than `XVECTOR (FOO)->size'.

	* process.c: Remove HAVE_INTTYPES_H condition from inclusion of
	inttypes.h, as a gnulib replacement is used if it not available in

2011-04-21  Eli Zaretskii  <eliz@gnu.org>

	Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
	* fileio.c (Finsert_file_contents): Don't limit file size to 1/4
	of MOST_POSITIVE_FIXNUM.  (Bug#8528)

	* coding.c (coding_alloc_by_realloc): Error out if destination
	will grow beyond MOST_POSITIVE_FIXNUM.

	charbuf for the composition carryover bytes.

2011-04-21  Eli Zaretskii  <eliz@gnu.org>

	produced by %s or %c overflows available buffer space.  (Bug#8545)

2011-04-28  Paul Eggert  <eggert@cs.ucla.edu>

	* doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).

2011-04-28  Eli Zaretskii  <eliz@gnu.org>

	* doprnt.c (doprnt): Don't return value smaller than the buffer
	size if the message was truncated.  (Bug#8545).

2011-04-28  Juanma Barranquero  <lekktu@gmail.com>

	* w32fns.c (Fx_change_window_property, Fx_delete_window_property)

	change.

2011-04-27  Paul Eggert  <eggert@cs.ucla.edu>

	* nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
	This makes this file independent of the recent pseudovector change.

2011-04-26  Paul Eggert  <eggert@cs.ucla.edu>

	* keyboard.c (handle_user_signal): Fix pointer signedness problem.

	* gnutls.c (emacs_gnutls_handle_error): Remove unused local.
	(Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
	Remove unused local.
	(emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.

	* lisp.h: Fix a problem with aliasing and vector headers.  (Bug#8546)
	GCC 4.6.0 optimizes based on type-based alias analysis.
	For example, if b is of type struct buffer * and v of type struct
	Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
	!= &v->size, and therefore "v->size = 1; b->size = 2; return
	v->size;" must therefore return 1.  This assumption is incorrect
	for Emacs, since it type-puns struct Lisp_Vector * with many other
	types.  To fix this problem, this patch adds a new type struct
	vectorlike_header that documents the constraints on layout of vectors
	and pseudovectors, and helps optimizing compilers not get fooled
	by Emacs's type punning.  It also adds the macros XSETTYPED_PVECTYPE
	XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
	* lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
	the size member.
	(XSETPVECTYPE): Rewrite in terms of new macro.
	(XSETPVECTYPESIZE): New macro, specifying both type and size.
	This is a bit clearer, and further avoids the possibility of
	undesirable aliasing.
	(XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
	(XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
	(XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
	since Lisp_Subr is a special case (no "next" field).
	(ASIZE): Now uses header.size rather than size.
	All previous uses of XVECTOR (foo)->size replaced to use this macro,
	to avoid the hassle of writing XVECTOR (foo)->header.size.
	(struct vectorlike_header): New type.
	(TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
	object, to help avoid aliasing.
	(PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
	(SUBRP): Likewise, since Lisp_Subr is a special case.
	* lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
	(struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
	(struct Lisp_Hash_Table): Combine first two members into a single
	struct vectorlike_header member.  All uses of "size" and "next" members
	changed to be "header.size" and "header.next".
	* buffer.h (struct buffer): Likewise.
	* font.h (struct font_spec, struct font_entity, struct font): Likewise.
	* frame.h (struct frame): Likewise.
	* process.h (struct Lisp_Process): Likewise.
	* termhooks.h (struct terminal): Likewise.
	* window.c (struct save_window_data, struct saved_window): Likewise.
	* window.h (struct window): Likewise.
	* alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
	Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
	* buffer.c (init_buffer_once): Likewise.
	* lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
	special case.
	* process.c (Fformat_network_address): Use local var for size,
	for brevity.

	* bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.

	Make the Lisp reader and string-to-float more consistent (Bug#8525)
	* data.c (atof): Remove decl; no longer used or needed.
	(digit_to_number): Move to lread.c.
	(Fstring_to_number): Use new string_to_number function, to be
	consistent with how the Lisp reader treats infinities and NaNs.
	Do not assume that floating-point numbers represent EMACS_INT
	without losing information; this is not true on most 64-bit hosts.
	Avoid double-rounding errors, by insisting on integers when
	parsing non-base-10 numbers, as the documentation specifies.
	* lisp.h (string_to_number): New decl, replacing ...
	(isfloat_string): Remove.
	* lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
	(read1): Do not accept +. and -. as integers; this
	appears to have been a coding error.  Similarly, do not accept
	strings like +-1e0 as floating point numbers.  Do not report
	overflow for integer overflows unless the base is not 10 which
	means we have no simple and reliable way to continue.
	Break out the floating-point parsing into a new
	function string_to_number, so that Fstring_to_number parses
	floating point numbers consistently with the Lisp reader.
	(digit_to_number): Move here from data.c.  Make it static inline.
	(E_CHAR, EXP_INT): Remove, replacing with ...
	(E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
	(string_to_number): New function, replacing isfloat_string.
	This function checks for valid syntax and produces the resulting
	Lisp float number too.  Rework it so that string-to-number
	no longer mishandles examples like "1.0e+".  Use strtoumax,
	so that overflow for non-base-10 numbers is reported only when
	there's no portable and simple way to convert to floating point.

	* textprop.c (set_text_properties_1): Rewrite for clarity,
	and to avoid GCC warning about integer overflow.

	* intervals.h (struct interval): Use EMACS_INT for members
	where EMACS_UINT might cause problems.  See
	<http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
	(CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
	* intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
	All uses changed.
	(offset_intervals): Tell GCC not to worry about length overflow
	when negating a negative length.

	* alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
	(overrun_check_free): Likewise.

	* alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
	in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
	word size.

	* gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
	(gnutls_make_error): Rename local to avoid shadowing.
	(gnutls_emacs_global_deinit): ifdef out; not used.
	(Fgnutls_boot): Use const for pointer to readonly storage.
	Comment out unused local.  Fix pointer signedness problems.

	* lread.c (openp): Don't stuff size_t into an 'int'.
	Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
	about possible signed overflow.

	* gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
	(GDK_KEY_g): Don't define if already defined.
	(xg_prepare_tooltip): Avoid pointer signedness problem.
	(xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.

	* process.c (Fnetwork_interface_info): Avoid left-shift undefined
	behavior with 1 << 31.  GCC 4.6.0 warns about this on 32-bit hosts.

	* xfns.c (Fx_window_property): Simplify a bit,
	to make a bit faster and to avoid GCC 4.6.0 warning.
	* xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.

	* fns.c (internal_equal): Don't assume size_t fits in int.

	* alloc.c (compact_small_strings): Tighten assertion a little.

	Replace pEd with more-general pI, and fix some printf arg casts.
	* lisp.h (pI): New macro, generalizing old pEd macro to other
	conversion specifiers.  For example, use "...%"pI"d..." rather
	than "...%"pEd"...".
	(pEd): Remove.  All uses replaced with similar uses of pI.
	* src/m/amdx86-64.h, src/m/ia64.h, src/m/ibms390x.h: Likewise.
	* alloc.c (check_pure_size): Don't overflow by converting size to int.
	* bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
	* data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
	* dbusbind.c (xd_append_arg): Use pI to avoid cast.
	(Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
	* font.c (font_unparse_xlfd): Avoid potential buffer overrun on
	64-bit hosts.
	(font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
	* keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
	* print.c (safe_debug_print, print_object): Likewise.
	(print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
	to int.
	Use pI instead of if-then-else-abort.  Use %p to avoid casts,
	avoiding the 0 flag, which is not portable.
	* process.c (Fmake_network_process): Use pI to avoid cast.
	* region-cache.c (pp_cache): Likewise.
	* xdisp.c (decode_mode_spec): Likewise.
	* xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
	behavior on 64-bit hosts with printf arg.
	* xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
	(x_stop_queuing_selection_requests): Likewise.
	(x_get_window_property): Don't truncate byte count to an 'int'
	when tracing.

	* frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
	here, since it parses constructs like leading '-' and spaces,
	which are not wanted; and it overflows with large numbers.
	Instead, simply match F[0-9]+, which is what is wanted anyway.

	* alloc.c: Remove unportable assumptions about struct layout.
	(SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
	(SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
	(allocate_vectorlike, make_pure_vector): Use the new macros,
	plus offsetof, to remove unportable assumptions about struct layout.
	These assumptions hold on all porting targets that I know of, but
	they are not guaranteed, they're easy to remove, and removing them
	makes further changes easier.

	* alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
	This doesn't fix a bug but makes the code clearer.
	(string_overrun_cookie): Now const.  Use initializers that
	don't formally overflow signed char, to avoid warnings.
	(allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
	can cause Emacs to crash when string overrun checking is enabled.
	(allocate_buffer): Don't assume sizeof (struct buffer) is a
	multiple of sizeof (EMACS_INT); it need not be, if
	alignof(EMACS_INT) < sizeof (EMACS_INT).
	(check_sblock, check_string_bytes, check_string_free_list): Protoize.

2011-04-26  Juanma Barranquero  <lekktu@gmail.com>

	supported by the function.  Use SAFE_ALLOCA instead of always
	using `alloca'.

	docstring.  Start callback support.
	(emacs_gnutls_handshake): Add Woe32 support.  Retry handshake
	unless a fatal error occurred.  Call gnutls_alert_send_appropriate
	on error.  Return error code.

	* character.c (char_string): Use %x to display the (unsigned)
	codepoint of an invalid character, to avoid displaying a bogus
	negative value.

	* font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
	`error', not SYMBOL_NAME itself.

	* coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
	character arguments to `error'.

	* charset.c (check_iso_charset_parameter): Fix incorrect argument

	FINAL_CHAR is a character, and use %c when it is passed as
	argument to `error'.

	* atimer.h (run_all_atimers): Remove; not exported.

	font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
	* font.c (copy_font_spec): Rename from Fcopy_font_spec, since it

	Make Emacs functions such as Fatom 'static' by default.
	This makes it easier for human readers (and static analyzers)

	DEFUN now defines a static function.  To make the function external
	so that it can be used in other C modules, use the new macro DEFUE.

2011-04-12  Andreas Schwab  <schwab@linux-m68k.org>

	* charset.c (Fclear_charset_maps): Use xfree instead of free.

2011-04-12  Paul Eggert  <eggert@cs.ucla.edu>

	* sysdep.c (emacs_read, emacs_write): Check for negative sizes
	since callers should never pass a negative size.
	Change the signature to match that of plain 'read' and 'write'; see
	<http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
	* lisp.h: Update prototypes of emacs_write and emacs_read.

2011-04-11  Eli Zaretskii  <eliz@gnu.org>

	* xdisp.c (redisplay_window): Don't try to determine the character
	position of the scroll margin if the window start point w->startp
	is outside the buffer's accessible region.  (Bug#8468)

2011-04-10  Eli Zaretskii  <eliz@gnu.org>

	Fix write-region and its subroutines for buffers > 2GB.
	* fileio.c (a_write, e_write): Modify declaration of arguments and
	local variables to support buffers larger than 2GB.
	(Fcopy_file): Use EMACS_INT for return value of emacs_read.

	* sysdep.c (emacs_write, emacs_read): Use ssize_t for last
	argument, local variables, and return value.

	* lisp.h: Update prototypes of emacs_write and emacs_read.

	* sound.c (vox_write): Use ssize_t for return value of emacs_write.

2011-04-10  Paul Eggert  <eggert@cs.ucla.edu>

	* xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.

	Fix more problems found by GCC 4.6.0's static checks.

	* xdisp.c (vmessage): Use a better test for character truncation.

	* charset.c (load_charset_map): <, not <=, for optimization,
	and to avoid potential problems with integer overflow.
	* chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
	* casetab.c (set_identity, shuffle): Likewise.
	* editfns.c (Fformat): Likewise.
	* syntax.c (skip_chars): Likewise.

	* xmenu.c (set_frame_menubar): Allocate smaller local vectors.
	This also lets GCC 4.6.0 generate slightly better loop code.

	* callint.c (Fcall_interactively): <, not <=, for optimization.
	(Fcall_interactively): Count the number of arguments produced,
	not the number of arguments given.  This is simpler and lets GCC
	4.6.0 generate slightly better code.

	* ftfont.c: Distingish more carefully between FcChar8 and char.
	The previous code passed unsigned char * to a functions like
	strlen and xstrcasecmp that expect char *, which does not
	conform to the C standard.
	(get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
	arguments to FcPatternGetString, and explicitly cast FcChar8 * to
	char * when the C standard requires it.

	* keyboard.c (read_char): Remove unused var.

	* eval.c: Port to Windows vsnprintf (Bug#8435).
	Include <limits.h>.
	(SIZE_MAX): Define if the headers do not.
	(verror): Do not give up if vsnprintf returns a negative count.
	Instead, grow the buffer.  This ports to Windows vsnprintf, which
	does not conform to C99.  Problem reported by Eli Zaretskii.
	Also, simplify the allocation scheme, by avoiding the need for
	calling realloc, and removing the ALLOCATED variable.

	* eval.c (verror): Initial buffer size is 4000 (not 200) bytes.

	Remove invocations of doprnt, as Emacs now uses vsnprintf.
	But keep the doprint source code for now, as we might revamp it
	and use it again (Bug#8435).
	* lisp.h (doprnt): Remove.
	* Makefile.in (base_obj): Remove doprnt.o.
	* deps.mk (doprnt.o): Remove.

	error: Print 32- and 64-bit integers portably (Bug#8435).
	Without this change, on typical 64-bit hosts error ("...%d...", N)
	was used to print both 32- and 64-bit integers N, which relied on
	undefined behavior.
	* lisp.h, src/m/amdx86-64.h, src/m/ia64.h, src/m/ibms390x.h (pEd):
	New macro.
	* lisp.h (error, verror): Mark as printf-like functions.
	* eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
	Report overflow in size calculations when allocating printf buffer.
	Do not truncate output string at its first null byte.
	* xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
	Truncate the output at a character boundary, since vsnprintf does not
	do that.
	* charset.c (check_iso_charset_parameter): Convert internal
	character to string before calling 'error', since %c now has the
	printf meaning.
	* coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
	overflow when computing char to be passed to 'error'.  Do not
	pass Lisp_Object to 'error'; pass the integer instead.
	* nsfns.m (Fns_do_applescript): Use int, not long, since it's
	formatted with plain %d.

	* eval.c (internal_lisp_condition_case): Don't pass spurious arg.

	* keyboard.c (access_keymap_keyremap): Print func name, not garbage.

	* coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.

	* xterm.c (x_catch_errors): Remove duplicate declaration.

	* term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.

	* xdisp.c, lisp.h (message_nolog): Remove; unused.

2011-04-10  Jim Meyering  <meyering@redhat.com>

	use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
	* gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
	return ssize_t not "int", and use size_t as the buffer length.
	(emacs_gnutls_write): Likewise, and make the buffer pointer "const".
	* gnutls.h: Update declarations.
	* process.c (read_process_output): Use ssize_t, to match.
	(send_process): Likewise.

	(Fmatch_data): Make some `int' variables be EMACS_INT.

	* xdisp.c (display_count_lines): 3rd argument and return value now
	EMACS_INT.  All callers changed.

	affects only one use, in DECODE_COMPOSITION_RULE, which is changed.

	(wordify): Omit three unnecessary tests.

	* indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.

	that is set but not used.

	* print.c (print_object): Remove var that is set but not used.

	Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
	The gnulib version avoids calling malloc in the usual case,

	* print.c (Fwith_output_to_temp_buffer): Move to subr.el.

	* lread.c (lisp_file_lexically_bound_p): New function.
	(Fload): Bind Qlexical_binding.
	(readevalloop): Remove `evalfun' arg.
	Bind Qinternal_interpreter_environment.
	(Feval_buffer): Bind Qlexical_binding.
	(defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
	Mark as dynamic.
	(syms_of_lread): Declare `lexical-binding'.

	* lisp.h (struct Lisp_Symbol): New field `declared_special'.

	* keyboard.c (eval_dyn): New fun.
	(menu_item_eval_property): Use it.

	* image.c (parse_image_spec): Use Ffunctionp.

	* fns.c (concat, mapcar1): Accept byte-code-functions.

	* eval.c (Fsetq): Handle lexical vars.
	(Fdefun, Fdefmacro, Ffunction): Make closures when needed.
	(Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
	(FletX, Flet): Obey lexical binding.
	(Fcommandp): Handle closures.
	(Feval): New `lexical' arg.
	(eval_sub): New function extracted from Feval.  Use it almost
	everywhere where Feval was used.  Look up vars in lexical env.
	Handle closures.
	(Ffunctionp): Move from subr.el.
	(Ffuncall): Handle closures.
	(apply_lambda): Remove `eval_flags'.
	(funcall_lambda): Handle closures and new byte-code-functions.
	(Fspecial_variable_p): New function.
	(syms_of_eval): Initialize the Vinternal_interpreter_environment var,
	but without exporting it to Lisp.

	* doc.c (Fdocumentation, store_function_docstring):
	* data.c (Finteractive_form): Handle closures.

	* callint.c (Fcall_interactively): Preserve lexical-binding mode for
	interactive spec.

	* bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
	New byte-codes.
	(exec_byte_code): New function extracted from Fbyte_code to handle new
	calling convention for byte-code-functions.  Add new byte-codes.

2011-03-31  Eli Zaretskii  <eliz@gnu.org>

	* xdisp.c (SCROLL_LIMIT): New macro.
	(try_scrolling): Use it when setting scroll_limit.
	Limit scrolling to 100 screen lines.
	(redisplay_window): Even when falling back on "recentering",
	position point in the window according to scroll-conservatively,
	scroll-margin, and scroll-*-aggressively variables.  (Bug#6671)

	(try_scrolling): When point is above the window, allow searching
	as far as scroll_max, or one screenful, to compute vertical
	distance from PT to the scroll margin position.  This prevents
	try_scrolling from unnecessarily failing when
	scroll-conservatively is set to a value slightly larger than the
	window height.  Clean up the case of PT below the margin at bottom
	of window: scroll_max can no longer be INT_MAX.  When aggressive
	scrolling is in use, don't let point enter the opposite scroll
	margin as result of the scroll.
	(syms_of_xdisp) <scroll-conservatively>: Document the
	threshold of 100 lines for never-recentering scrolling.

2011-03-31  Juanma Barranquero  <lekktu@gmail.com>

	`this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org.  All callers changed.

	unused since 1999-07-21T21:43:52Z!gerd@gnu.org.  All callers changed.

	* indent.c (Fvertical_motion):
	* window.c (window_scroll_pixel_based, Frecenter):
	Don't pass `need_y_p' to `move_it_by_lines'.

2011-03-30  Stefan Monnier  <monnier@iro.umontreal.ca>

	* eval.c (struct backtrace): Don't cheat with negative numbers, but do
	steal a few bits to be more compact.

	binding" message (bug#7967).

2011-03-30  Paul Eggert  <eggert@cs.ucla.edu>

	Fix more problems found by GCC 4.6.0's static checks.

	* unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
	Remove unused local var.

	* editfns.c (Fmessage_box): Remove unused local var.

	* window.c (shrink_windows): Omit unused local var.
	* menu.c (digest_single_submenu): Omit unused local var.
	* dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
	Omit unused local var.

	* keyboard.c (parse_modifiers_uncached, parse_modifiers):
	Don't assume string length fits in int.
	(keyremap_step, read_key_sequence): Use size_t for sizes.
	(read_key_sequence): Don't check last_real_key_start redundantly.

	* callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
	instead of alloca (Bug#8344).

	* eval.c (Fbacktrace): Don't assume nargs fits in int.
	(Fbacktrace_frame): Don't assume nframes fits in int.

	efficiency gain, and to bypass a gcc -Wstrict-overflow warning.

	* keyboard.c, keyboard.h (num_input_events): Now size_t.
	This avoids undefined behavior on integer overflow, and is a bit
	more convenient anyway since it is compared to a size_t variable.

	Variadic C functions now count arguments with size_t, not int.
	This avoids an unnecessary limitation on 64-bit machines, which
	caused (substring ...) to crash on large vectors (Bug#8344).
	* lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
	(DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
	All variadic functions and their callers changed accordingly.

	* fns.c (concat): Likewise.
	* frame.c (x_set_frame_parameters): Likewise.
	* fns.c (get_key_arg): Now accepts and returns size_t, and returns
	0 if not found, not -1.  All callers changed.

	* alloc.c (garbage_collect): Don't assume stack size fits in int.
	(stack_copy_size): Now size_t, not int.
	(stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.

	(syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
	Vcommand_hook_internal.

	* eval.c (enum run_hooks_condition): Remove.
	(funcall_nil, funcall_not): New functions.
	(run_hook_with_args): Call each function through a `funcall' argument.

	(Frun_hook_with_args_until_failure): Adjust accordingly.
	(run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.

	used outside xdisp.c).
	(cursor_row_p): Remove parameter `w', unused since
	2000-10-17T16:08:57Z!gerd@gnu.org.  All callers changed.
	(decode_mode_spec): Remove parameter `precision', introduced during
	Gerd Moellmann's rewrite at 1999-07-21T21:43:52Z!gerd@gnu.org, but never used.
	All callers changed.

2011-03-23  Paul Eggert  <eggert@cs.ucla.edu>

	Fix more problems found by GCC 4.5.2's static checks.

	* coding.c (encode_coding_raw_text): Avoid unnecessary test
	the first time through the loop, since we know p0 < p1 then.
	This also avoids a gcc -Wstrict-overflow warning.

	* lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
	leading to a memory leak, possible in functions like
	load_charset_map_from_file that can allocate an unbounded number
	of objects (Bug#8318).

	* xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
	that could (at least in theory) be that large.

	* xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
	This is less likely to overflow, and avoids undefined behavior if
	overflow does occur.  All callers changed.  Use strtoul to scan
	for the unsigned long integer.
	(pint2hrstr): Simplify and tune code slightly.
	This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

	* scroll.c (do_scrolling): Work around GCC bug 48228.
	See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.

	* frame.c (Fmodify_frame_parameters): Simplify loop counter.
	This also avoids a warning with gcc -Wstrict-overflow.
	(validate_x_resource_name): Simplify count usage.
	This also avoids a warning with gcc -Wstrict-overflow.

	* fileio.c (Fcopy_file): Report error if fchown or fchmod
	fail (Bug#8306).

	* emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).

	* process.c (Fmake_network_process): Use socklen_t, not int,
	where POSIX says socklen_t is required in portable programs.
	This fixes a porting bug on hosts like 64-bit HP-UX, where
	socklen_t is wider than int (Bug#8277).
	(Fmake_network_process, server_accept_connection):
	(wait_reading_process_output, read_process_output):
	Likewise.

	* process.c: Rename or move locals to avoid shadowing.
	(list_processes_1, Fmake_network_process):

	(process_send_signal): Add cast to avoid pointer signedness problem.
	(FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
	(create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).

	Make tparam.h and terminfo.c consistent.
	* cm.c (tputs, tgoto, BC, UP): Remove extern decls.
	Include tparam.h instead, since it declares them.
	* cm.h (PC): Remove extern decl; tparam.h now does this.
	* deps.mk (cm.o, terminfo.o): Depend on tparam.h.

	(GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second

	changed.
	* dired.c (directory_files_internal, file_name_completion):
	Rename locals to avoid shadowing.

	Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
	An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
	dired.c's scmp function, had undefined behavior.
	* lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
	(NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
	* buffer.h: ... to here, because these macros use current_buffer,

	current_buffer in scope now, rather than later when the macros
	are used.
	(downcase, upcase1): New static inline functions.
	(DOWNCASE, UPCASE1): Reimplement using these functions.

	* lisp.h (case_temp1, case_temp2): Remove their decls.

	(Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
	signedness issues.
	(Fset_file_times, Finsert_file_contents, auto_save_error):

	(lock_file_1): Rename local to avoid shadowing.

	* buffer.c (fix_overlays_before): Mark locals as initialized.
	(fix_start_end_in_overlays): Likewise.  This function should be
	simplified by using pointers-to-pointers, but that's a different
	matter.
	(switch_to_buffer_1): Now static.
	(Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
	(report_overlay_modification): Rename locals to avoid shadowing.

	* sysdep.c (system_process_attributes): Rename vars to avoid shadowing.

	* process.c (serial_open, serial_configure): Move decls from here ...
	* systty.h: ... to here, so that they can be checked.

	Improve quality of tests for time stamp overflow.
	For example, without this patch (encode-time 0 0 0 1 1
	1152921504606846976) returns the obviously-bogus value (-948597
