	Standardize on VIRT_ADDR_VARIES behavior (Bug#10042).
	Otherwise, valgrind does not work on some platforms.
	Problem reported by Andreas Schwab in
	<http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
	* puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
	is set, removing the need for VIRT_ADDRESS_VARIES.
	(PURE_P): Use a more-efficient implementation that needs just one
	comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
	number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
	to 4 (xorl, subq, cmpq, setbe).

	and the cursor position is out of bounds, behave as if the cursor
	position were at the window margin.  (Bug#10075)

2011-11-18  Chong Yidong  <cyd@gnu.org>

	* window.c (Fwindow_combination_limit): Make first argument

	(compute_line_metrics): Call row_hash, instead of computing the
	hash code inline.

	hash code of a row, instead of duplicating code from xdisp.c.

	* dispextern.h (row_hash): Add prototype.

2011-11-18  Tassilo Horn  <tassilo@member.fsf.org>

	* frame.c (delete_frame): Don't delete the terminal when the last

	* image.c (imagemagick_load_image): Fix typo.

2011-11-14  Eli Zaretskii  <eliz@gnu.org>

	* xdisp.c (display_line): Move the call to
	highlight_trailing_whitespace before the call to
	compute_line_metrics, since the latter needs to see the final
	faces of all the glyphs to compute ROW's hash value.
	Fixes assertion violations in row_equal_p.  (Bug#10035)

2011-11-14  Juanma Barranquero  <lekktu@gmail.com>

	* w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,

2011-11-08  Paul Eggert  <eggert@cs.ucla.edu>

	Avoid some portability problems by eschewing 'extern inline' functions.
	The trivial performance wins aren't worth the portability hassles; see
	<http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>

	(get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
	New functions.
	(w32font_open_internal, compute_metrics):
	Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
	instead of calling the "wide" APIs directly.

	* gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
	non-NULL, regardless of GNUTLS_INITSTAGE.
	(Fgnutls_boot): Cleanups.  Call emacs_gnutls_deinit if we signal
	an error.  Set process slots as soon as we allocate them.

	* gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.

2011-10-27  Chong Yidong  <cyd@gnu.org>

	* gnutls.c (emacs_gnutls_deinit): New function.
	Deallocate credentials structures as well as calling gnutls_deinit.
	(Fgnutls_deinit, Fgnutls_boot): Use it.

	* process.c (make_process): Initialize GnuTLS credentials to NULL.
	(deactivate_process): Call emacs_gnutls_deinit.

	* w32fns.c (w32_default_color_map): New function,
	extracted from Fw32_default_color_map.
	(Fw32_default_color_map, Fx_open_connection): Use it.  (Bug#9785)

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).

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.
