ChangeLog

2012-05-23  Eli Zaretskii  <eliz@gnu.org>

	* charset.c (maybe_unify_char): Inhibit relocation of buffer text
	for the duration of call to load_charset, to avoid problems with
	callers of maybe_unify_char that access buffer text through C
	pointers.

	* ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
	decrement the inhibition flag, instead of just setting or
	resetting it.

2012-05-24  Ken Brown  <kbrown@cornell.edu>

	* callproc.c (Fcall_process): Restore a line that was accidentally
	commented out in the 2011-02-13 change (bug#11547).

2012-05-23  Eli Zaretskii  <eliz@gnu.org>

	* lisp.h [REL_ALLOC]: Add prototypes for external functions
	defined on ralloc.c.

	* buffer.c [REL_ALLOC]: Remove prototypes of
	r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
	they are now on lisp.h.

	* ralloc.c (r_alloc_inhibit_buffer_relocation): New function.

	* search.c (search_buffer): Use it to inhibit relocation of buffer
	text while re_search_2 is doing its job, because re_search_2 is
	passed C pointers to buffer text.  (Bug#11519)

2012-05-21  Eli Zaretskii  <eliz@gnu.org>

	* msdos.c (internal_terminal_init) <Vwindow_system_version>:
	Update value to 24.

2012-05-19  Eli Zaretskii  <eliz@gnu.org>

	* xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
	state after an additional call to move_it_in_display_line_to, keep
	the values of it->max_ascent and it->max_descent found for the
	entire line.
	(pos_visible_p): Revert the comparison against bottom_y to what it
	was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
	(Bug#11464)

2012-05-15  Eli Zaretskii  <eliz@gnu.org>

	* xdisp.c (pos_visible_p): Fix last change.  (Bug#11464)

2012-05-13  Eli Zaretskii  <eliz@gnu.org>

	* xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
	already have overlays loaded.
	(handle_single_display_spec): Before returning without displaying
	fringe bitmap, synchronize the bidi iterator with the main display
	iterator, by calling iterate_out_of_display_property.
	(iterate_out_of_display_property): Detect buffer iteration by
	testing that it->string is a Lisp string.
	(get_next_display_element): When the current object is exhausted,
	and there's something on it->stack, call set_iterator_to_next to
	proceed with what's on the stack, instead of returning zero.
	(set_iterator_to_next): If called at the end of a Lisp string,
	proceed to consider_string_end without incrementing string
	position.  Don't increment display vector index past the end of
	the display vector.  (Bug#11417)
	(pos_visible_p): Don't report a position visible when move_it_to
	stopped at the last line of window, which happens to be scanned
	backwards by the bidi iteration.  (Bug#11464)

2012-05-11  Eli Zaretskii  <eliz@gnu.org>

	* xdisp.c (handle_single_display_spec): Return 1 for left-margin
	and right-margin display specs even if the spec is invalid or we
	are on a TTY, and thus unable to display on the fringes.  That's
	because the text with the property will not be displayed anyway,
	so we need to signal to the caller that this is a "replacing"
	display spec.  This fixes display when the spec is invalid or we
	are on a TTY.

2012-05-09  Paul Eggert  <eggert@cs.ucla.edu>

	* unexaix.c (make_hdr): Fix typo in prototype.
	This bug broke the build on AIX.  Problem reported by Gilles Pion.

2012-05-05  Eli Zaretskii  <eliz@gnu.org>

	* w32proc.c (new_child): Force Windows to reserve only 64KB of
	stack for each reader_thread, instead of defaulting to 8MB
	determined by the linker.  This avoids failures in creating
	subprocesses on Windows 7, see the discussion in this thread:
	http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.

2012-05-02  Jim Meyering  <meyering@redhat.com>

	* w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).

2012-04-29  Eli Zaretskii  <eliz@gnu.org>

	* xdisp.c (pos_visible_p): If already at a newline from the
	display string before the 'while' loop, don't walk back the glyphs
	from it3.glyph_row.  Solves assertion violation when the display
	string begins with a newline (egg.el).  (Bug#11367)

2012-04-24  Chong Yidong  <cyd@gnu.org>

	* xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).

2012-04-23  Eli Zaretskii  <eliz@gnu.org>

	* xdisp.c (pos_visible_p): If the window start position is beyond
	ZV, start the display from buffer beginning.  Prevents assertion
	violation in init_iterator when the minibuffer window is scrolled
	via the scroll bar.

	* window.c (window_scroll_pixel_based): Likewise.

2012-04-23  Chong Yidong  <cyd@gnu.org>

	* keymap.c (where_is_internal): Doc fix (Bug#10872).

2012-04-20  Glenn Morris  <rgm@gnu.org>

	* fileio.c (Fcopy_file, Fset_file_selinux_context):
	Ignore ENOTSUP failures from setfilecon functions.  (Bug#11245)

2012-04-20  Eli Zaretskii  <eliz@gnu.org>

	* dispnew.c (swap_glyph_pointers, copy_row_except_pointers): Don't
	overrun array limits of glyph row's used[] array.  (Bug#11288)

2012-04-20  Chong Yidong  <cyd@gnu.org>

	* process.c (wait_reading_process_output): If EIO occurs on a pty,
	set the status to "failed" and ensure that sentinel is run.

2012-04-18  Glenn Morris  <rgm@gnu.org>

	* process.c (Fset_process_inherit_coding_system_flag)
	(Fset_process_query_on_exit_flag): Doc fix (mention return value).
	(Fmake_network_process, Fmake_serial_process): Doc fix.

2012-04-17  Eli Zaretskii  <eliz@gnu.org>

	* xdisp.c (string_buffer_position_lim): Limit starting position to
	BEGV.
	(set_cursor_from_row): If called for a mode-line or header-line
	row, return zero immediately.
	(try_cursor_movement): If inside continuation line, don't back up
	farther than the first row after the header line, if any.  Don't
	consider the header-line row as "partially visible", even if
	MATRIX_ROW_PARTIALLY_VISIBLE_P returns non-zero.  (Bug#11261)

2012-04-13  Atsuo Ohki  <ohki@gssm.otsuka.tsukuba.ac.jp>  (tiny change)

	* lread.c (lisp_file_lexically_bound_p): Fix hang at ";-*-\n" (bug#11238).

2012-04-10  Teodor Zlatanov  <tzz@lifelogs.com>

	* process.c (make_process):
	* process.h: Add integer `gnutls_handshakes_tried' member to
	process struct.

	* gnutls.h: Add `GNUTLS_EMACS_HANDSHAKES_LIMIT' upper limit.
	Add convenience `GNUTLS_LOG2i' macro.

	* gnutls.c (gnutls_log_function2i): Convenience log function.
	(emacs_gnutls_read): Use new log functions,
	`gnutls_handshakes_tried' process member, and
	`GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
	attempts per process (connection).

2012-04-09  Eli Zaretskii  <eliz@gnu.org>

	* xdisp.c (find_last_unchanged_at_beg_row): Don't consider a row
	"unchanged" if its end.pos is beyond ZV.  (Bug#11199)

2012-04-09  Jan Djärv  <jan.h.d@swipnet.se>

	* nsterm.m (constrainFrameRect): Always constrain when there is only
	one screen (Bug#10962).

2012-04-06  Eli Zaretskii  <eliz@gnu.org>

	* buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
	* character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
	about subtle differences between FETCH_CHAR* and STRING_CHAR*
	macros related to unification of CJK characters.  For the details,
	see the discussion following the message here:
	http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.

2012-04-04  Chong Yidong  <cyd@gnu.org>

	* w32menu.c (is_simple_dialog): Properly check lisp types.
	(Bug#11141)

2012-03-31  Eli Zaretskii  <eliz@gnu.org>

	* xdisp.c (move_it_by_lines): When DVPOS is positive, and the
	position we get to after a call to move_it_to fails the
	IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
	only if we wind up in a string from display property.  (Bug#11063)

	* window.c (Fdelete_other_windows_internal): Invalidate the row
	and column information about mouse highlight, so that redisplay
	restores it after reallocating the glyph matrices.  (Bug#7464)

	* xdisp.c (set_cursor_from_row): If `cursor' property on a display
	string comes from a `display' text property, use the buffer
	position of that property as if we actually saw that position in
	the row's glyphs.
	(move_it_by_lines): Remove the assertion that
	"it->current_x == 0 && it->hpos == 0" which can be legitimately
	violated when there's a before-string at the beginning of a line.
	(Bug#11063)

2012-03-30  Eli Zaretskii  <eliz@gnu.org>

	* xdisp.c (append_space_for_newline): If the default face was
	remapped, use the remapped face for the appended newline.
	(extend_face_to_end_of_line): Use the remapped default face for
	extending the face to the end of the line.
	(display_line): Call extend_face_to_end_of_line when the default
	face was remapped.  (Bug#11068)

2012-03-29  Eli Zaretskii  <eliz@gnu.org>

	* s/ms-w32.h: Discourage from defining HAVE_GETCWD.

2012-03-28  Stefan Monnier  <monnier@iro.umontreal.ca>

	* keyboard.c (safe_run_hooks_error): Don't unquote strings.

2012-03-27  Glenn Morris  <rgm@gnu.org>

	* search.c (Fword_search_backward_lax, Fword_search_forward_lax):
	Doc fixes.

2012-03-26  Kenichi Handa  <handa@m17n.org>

	* dispextern.h (struct glyph): Fix previous change.  Change the
	bit length of glyphless.ch to 25 (Bug#11082).

2012-03-26  Chong Yidong  <cyd@gnu.org>

	* keyboard.c (Vselection_inhibit_update_commands): New variable.
	(command_loop_1): Use it; inhibit selection update for
	handle-select-window too (Bug#8996).

2012-03-25  Fabrice Popineau  <fabrice.popineau@supelec.fr>

	* w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.

2012-03-25  Kenichi Handa  <handa@m17n.org>

	* dispextern.h (struct glyph): Change the bit length of
	glyphless.ch to 22 to make the member glyphless fit in 32 bits.

2012-03-24  Eli Zaretskii  <eliz@gnu.org>

	* s/ms-w32.h (tzname): Include time.h before redirecting to
	_tzname.  Fixes the MSVC build.  (Bug#9960)

2012-03-24  Andreas Schwab  <schwab@linux-m68k.org>

	* xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
	characters.

	* xterm.c (XTread_socket): Only modify handling_signal if
	!SYNC_INPUT.  (Bug#11080)

2012-03-23  Eli Zaretskii  <eliz@gnu.org>

	* bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
	FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES.  Prevents crashes
	when fetching a multibyte character consumes more bytes than
	CHAR_BYTES returns, due to unification of CJK characters in
	string_char.  (Bug#11073)

2012-03-23  Troels Nielsen  <bn.troels@gmail.com>  (tiny change)

	* process.c (wait_reading_process_output): Handle pty disconnect
	by refraining from sending oneself a SIGCHLD (bug#10933).

2012-03-21  Chong Yidong  <cyd@gnu.org>

	* xfaces.c (Vface_remapping_alist): Doc fix.

2012-03-20  Eli Zaretskii  <eliz@gnu.org>

	* w32proc.c (Fw32_set_console_codepage)
	(Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
	Doc fixes.

2012-03-20  Chong Yidong  <cyd@gnu.org>

	* dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
	to reflect default non-nil value of redisplay-dont-pause.

	* ftfont.c (ftfont_drive_otf): Mask bits of character code to make
	it fit in a valid range (Bug#11003).

2012-03-18  Eli Zaretskii  <eliz@gnu.org>

	* xdisp.c (cursor_row_p): Even if the glyph row ends in a string
	that is not from display property, accept the row as a "cursor
	row" if one of the string's character has a non-nil `cursor'
	property.  Fixes cursor positioning when there are newlines in
	overlay strings, e.g. in icomplete.el.  (Bug#11035)

2012-03-12  Paul Eggert  <eggert@cs.ucla.edu>

	* editfns.c (Fconstrain_to_field): Doc fix (Bug#9452).

2012-03-10  Chong Yidong  <cyd@gnu.org>

	* frame.c (other_visible_frames): Don't assume the selected frame
	is visible (Bug#10955).

2012-03-09  Stefan Monnier  <monnier@iro.umontreal.ca>

	* buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).

2012-03-08  Jan Djärv  <jan.h.d@swipnet.se>

	* gtkutil.c (x_wm_set_size_hint): Use one row in call to
	FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
	zero (Bug#10954).

2012-03-03  Glenn Morris  <rgm@gnu.org>

	* alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.

2012-03-02  Eli Zaretskii  <eliz@gnu.org>

	* xdisp.c (try_window_reusing_current_matrix): Don't move cursor
	position past the first glyph_row that ends at ZV.  (Bug#10902)
	(redisplay_window, next_element_from_string): Fix typos in
	comments.
	(redisplay_window): Pass to move_it_vertically the margin in
	pixels, not in screen lines.

2012-03-02  Glenn Morris  <rgm@gnu.org>

	* buffer.c (buffer-list-update-hook): Doc fix.

2012-02-29  Eli Zaretskii  <eliz@gnu.org>

	* xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
	push_it before setting up the iterator for the first overlay
	string, even if we have an empty string loaded.
	(next_overlay_string): If there's an empty string on the iterator
	stack, pop the stack.  (Bug#10903)

2012-02-25  Paul Eggert  <eggert@cs.ucla.edu>

	Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
	Suggested by Stefan Monnier in
	<http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
	* alloc.c (widen_to_Lisp_Object): New static function.
	(mark_memory): Also mark Lisp_Objects by fetching pointer words
	and widening them to Lisp_Objects.  This would work even if
	USE_LSB_TAG is defined and wide integers are used, which might
	happen in a future version of Emacs.

2012-02-25  Chong Yidong  <cyd@gnu.org>

	* fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
	Doc fix.

	requests in kbd_buffer, not just the next one (Bug#8869).

2012-02-23  Chong Yidong  <cyd@gnu.org>

	* xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
	call when setting menu-bar-lines and tool-bar-lines parameters.
	(unwind_create_frame_1): New helper function.

	* window.c (inhibit_window_configuration_change_hook): New var.
	(run_window_configuration_change_hook): Obey it.
	(syms_of_window): Initialize it.

2012-02-22  Chong Yidong  <cyd@gnu.org>

	* xterm.c (x_draw_image_relief): Add missing type check for

	* .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
	when computing $valmask.

	Fix crash due to non-contiguous EMACS_INT (Bug#10780).
	* lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
	(USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
	It's useless in that case, and it can cause problems on hosts
	that allocate halves of EMACS_INT values separately.
	Reported by Dan Horák.  Diagnosed by Andreas Schwab in
	<http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
	* mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
	UINTPTR_MAX >> VALBITS == 0.  This is required by the above change;
	it avoids undefined behavior on hosts where shifting right by more
	than the word width has undefined behavior.

2012-02-19  Chong Yidong  <cyd@gnu.org>

	* fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
	(Funhandled_file_name_directory, Ffile_name_as_directory)
	(Fdirectory_file_name, Fexpand_file_name)
	(Fsubstitute_in_file_name): Protect against invalid file handler
	return values (Bug#10845).

2012-02-18  Eli Zaretskii  <eliz@gnu.org>

	<http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.

2012-02-15  Chong Yidong  <cyd@gnu.org>

	* eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
	marked as special.  Also, starting docstrings with * is obsolete.

2012-02-13  Andreas Schwab  <schwab@linux-m68k.org>

2012-02-12  Chong Yidong  <cyd@gnu.org>

	* xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
	as that creates a dangerous corner case.

	* window.c (Fdelete_window_internal): Invalidate the mouse
	highlight (Bug#9904).

2012-02-12  Glenn Morris  <rgm@gnu.org>

	* xselect.c (Fx_own_selection_internal)
	(Fx_get_selection_internal, Fx_disown_selection_internal)
	(Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
	* nsselect.m (Fx_own_selection_internal)
	(Fx_disown_selection_internal, Fx_selection_exists_p)
	(Fx_selection_owner_p, Fx_get_selection_internal):
	Sync docs and argument specs with the xselect.c versions.

2012-02-11  Lars Ingebrigtsen  <larsi@gnus.org>

	* gnutls.c (emacs_gnutls_write): Don't infloop if sendto fails.

2012-02-11  Eli Zaretskii  <eliz@gnu.org>

	* image.c (Fimagemagick_types): Doc fix.

	* image.c (imagemagick-render-type): Change it from a lisp object

	Treat all values not equal to 0 the same.

2012-02-06  Chong Yidong  <cyd@gnu.org>

	* doc.c (store_function_docstring): Avoid applying docstring of

	(GCPRO1, GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6, UNGCPRO):
	Revert to old implementation (i.e., before 2011-03-11).

2011-11-20  Paul Eggert  <eggert@cs.ucla.edu>

	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).
	* alloc.c (pure): Always extern now, since that's the
	VIRT_ADDR_VARIES behavior.
	(PURE_POINTER_P): Use a single comparison, not two, for
	consistency with the new puresize.h.
	* lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
	* m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:
	Remove VIRT_ADDR_VARIES no longer needed.

	* xdisp.c (x_write_glyphs, draw_phys_cursor_glyph)
	(erase_phys_cursor, update_window_cursor, show_mouse_face)
	(cursor_in_mouse_face_p): If the cursor position is out of bounds,
	behave as if the cursor position were at the window margin.

	* window.c (get_phys_cursor_glyph): If the window is hscrolled,
	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
	non-optional, since it is meaningless for live windows like the
	selected window.

2011-11-18  Dmitry Antipov  <dmantipov@yandex.ru>

	* keymap.c (Fwhere_is_internal): Add missing RETURN_UNGCPROs.

	* xdisp.c (row_hash): New function, body extracted from
	compute_line_metrics.
	(compute_line_metrics): Call row_hash, instead of computing the
	hash code inline.

	* dispnew.c (verify_row_hash): Call row_hash for computing the
	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
	X frame is closed if emacs is built with GTK toolkit.

2011-11-17  Juanma Barranquero  <lekktu@gmail.com>

	* window.c (syms_of_window) <window-combination-resize>: Fix typo.

2011-11-17  Martin Rudalics  <rudalics@gmx.at>

	of Vwindow_splits.

2011-11-16  Juanma Barranquero  <lekktu@gmail.com>

	* 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,
	just return (bug#10044).

2011-11-12  Eli Zaretskii  <eliz@gnu.org>

	* makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
	with user-defined heap size.  Bump the default size of the temacs
	heap to 27MB, to avoid memory warning when running temacs.
