2014-03-23  Stefan Monnier  <monnier@iro.umontreal.ca>

	* buffer.c (struct sortvec): Add field `spriority'.
	(compare_overlays): Use it.
	(sort_overlays): Set it.

2014-03-23  Eli Zaretskii  <eliz@gnu.org>

	* xdisp.c (redisplay_window): If all previous attempts to find the
	cursor row failed, try a few alternatives before falling back to
	the top-most row of the window.  Use row_containing_pos.  (Bug#17047)

2014-03-22  Daniel Colascione  <dancol@dancol.org>

	* process.c (conv_sockaddr_to_lisp): When extracting the string
	names of AF_LOCAL sockets, stop before reading uninitialized
	memory.

2014-03-23  Daniel Colascione  <dancol@dancol.org>

	* process.c (DATAGRAM_CONN_P): Don't underflow datagram_address
	array.  (ASAN caught.)

2014-03-21  YAMAMOTO Mitsuharu  <mituharu@math.s.chiba-u.ac.jp>

	Fix regression introduced by patch for Bug#10500.
	* xterm.c (x_draw_image_relief): Respect Vtool_bar_button_margin.
	* w32term.c (x_draw_image_relief): Likewise.

2014-03-21  Martin Rudalics  <rudalics@gmx.at>

	* w32fns.c (w32_wnd_proc): For WM_WINDOWPOSCHANGING don't
	constrain frame size in SW_SHOWMAXIMIZED case so we can truly
	maximize a frame for odd default fonts.

2014-03-20  Paul Eggert  <eggert@cs.ucla.edu>

	* doc.c (store_function_docstring): Fix pointer signedness mismatch.

2014-03-20  Stefan Monnier  <monnier@iro.umontreal.ca>

	* doc.c (store_function_docstring): Warn when we don't know where to
	put a docstring.
	(Fsubstitute_command_keys): Don't advertise the fact that
	text-properties are dropped, since we think it's a bug that we'll fix
	in 24.5.

	* frame.h (SET_FRAME_VISIBLE): Keep frame_garbaged up to date.
	* xterm.c (handle_one_xevent) <MapNotify>: Don't garbage the frame.

2014-03-20  Glenn Morris  <rgm@gnu.org>

	* charset.c (init_charset): When we cannot find the charsets directory,
	mention if EMACSDATA is set.

2014-03-19  Paul Eggert  <eggert@cs.ucla.edu>

	* fns.c (Frandom): Fix rare bug where the result isn't random.

	Fix porting inconsistency about rounding to even.
	* floatfns.c (emacs_rint) [!HAVE_RINT]: Round to even.
	This way, the unusual !HAVE_RINT case acts like the usual
	HAVE_RINT case, and we can fix the documentation accordingly.

2014-03-19  Eli Zaretskii  <eliz@gnu.org>

	* w32fns.c (reset_modifiers): Zero out keystate[] before using it.
	(w32_wnd_proc): Initialize the dwHoverTime member of
	TRACKMOUSEEVENT structure.

2014-03-17  Teodor Zlatanov  <tzz@lifelogs.com>

	* gnutls.c (Fgnutls_boot): Fix case of :verify-error = t.

2014-03-16  Eli Zaretskii  <eliz@gnu.org>

	* search.c (find_newline): Speed up the function when using the
	newline cache, by halving the number of calls to
	region_cache_forward and region_cache_backward.  (Bug#16830)

2014-03-15  Juanma Barranquero  <lekktu@gmail.com>

	* buffer.c (Fset_buffer): Document return value (bug#17015).

2014-03-14  Martin Rudalics  <rudalics@gmx.at>

	* w32term.c (x_set_window_size): When frame-resize-pixelwise is
	nil, always resize character wise to avoid potential loss of the
	mode line (Bug#16923 related).

2014-03-12  Martin Rudalics  <rudalics@gmx.at>

	* frame.c (x_set_frame_parameters): Always calculate new sizes
	pixelwise to avoid potential loss when rounding.

2014-03-11  Dmitry Antipov  <dmantipov@yandex.ru>

	* xfns.c (x_set_mouse_color): Recolor vertical_drag_cursor.
	* xterm.c (x_free_frame_resources): Free all allocated cursors.

2014-03-10  Eli Zaretskii  <eliz@gnu.org>

	* w32.c (fstatat): Don't add an extra slash if the argument ends
	with a slash: this fails the subsequent call to stat_worker on
	Windows 9X.  Reported by oslsachem <oslsachem@gmail.com>.

2014-03-09  Martin Rudalics  <rudalics@gmx.at>

	* xdisp.c (Fwindow_text_pixel_size): Adjust doc-string.

2014-03-08  Jan Djärv  <jan.h.d@swipnet.se>

	* nsterm.h (MAC_OS_X_VERSION_10_9): Add.

	* nsterm.m (constrainFrameRect:toScreen:): Constrain normally
	when frame is only on one screen (Bug#14713).

2014-03-08  Eli Zaretskii  <eliz@gnu.org>

	* xdisp.c (move_it_in_display_line_to): If word-wrap is ON, and
	there's a valid wrap point in the display line, the last glyph
	cannot "just barely fit" on this row, because display_line doesn't
	let it.  Instead, proceed as if the last glyph didn't fit, so that
	we eventually back up the iterator to the wrap point.  This avoids
	delusional behavior of move_it_to, whereby it proceeds to the next
	display line, but sets current_x to zero for all the glyphs that
	without word-wrap would fit on the previous display line.
	One result was that visual-order cursor movement behaved erratically
	under word-wrap.
	(Fmove_point_visually): Add code to find the x coordinate of the
	last character before wrap point, under word-wrap on a TTY.

2014-03-07  Eli Zaretskii  <eliz@gnu.org>

	* xdisp.c (Fmove_point_visually): When under word-wrap, accept
	also return value of MOVE_POS_MATCH_OR_ZV from
	move_it_in_display_line_to, when moving from beginning of line to
	point's position.  (Bug#16961)

2014-03-07  Martin Rudalics  <rudalics@gmx.at>

	* buffer.c (Vbuffer_list_update_hook): Doc-string fix.
	* window.c (Fselect_window): Explain NORECORD and
	`buffer-list-update-hook' in doc-string.

2014-03-06  Martin Rudalics  <rudalics@gmx.at>

	* window.c (Fother_window_for_scrolling): Check that
	Vother_window_scroll_buffer is a buffer.

2014-03-06  Dmitry Antipov  <dmantipov@yandex.ru>

	* xterm.c (xim_initialize): Always pass a copy of resource name
	to XRegisterIMInstantiateCallback and eassert whether return
	value is True.  Passing copy is important because Xlib doesn't
	make its own copy and resource name argument usually points to
	SSDATA (Vx_resource_name), which may be changed from Lisp.
	(xim_close_display): For XUnregisterIMInstantiateCallback,
	always eassert return value and pass exactly the same values
	as were used for XRegisterIMInstantiateCallback.
	Otherwise XUnregisterIMInstantiateCallback will always fail.  See Xlib
	sources to check why if you are interested.

2014-03-05  Martin Rudalics  <rudalics@gmx.at>

	* dispnew.c (change_frame_size_1): Add new_lines instead of
	new_height, the latter may be still zero if passed as such.
	* window.c (Fwindow_pixel_height): Mention bottom divider in
	doc-string.

2014-03-05  Paul Eggert  <eggert@cs.ucla.edu>

	Fix "resource temporarily unavailable" with xgselect
	(Bug#16925).
	* xgselect.c: Include <stdbool.h>.
	(xg_select) [!USE_GTK]: Don't lose track of errno.

	Fix minor --enable-gcc-warnings issues.
	* widget.c (update_various_frame_slots, EmacsFrameResize):
	Avoid unused locals.  Prefer 'if' to '#if' when either will do.

2014-03-04  Ken Brown  <kbrown@cornell.edu>

	* gmalloc.c (aligned_alloc): Clarify the code by making `adj'
	represent the actual adjustment needed for alignment.

2014-03-04  Eli Zaretskii  <eliz@gnu.org>

	* gmalloc.c (aligned_alloc): Don't allocate more memory than
	needed, and don't reallocate if the initial allocation already
	fits the bill.  Suggested by Ken Brown <kbrown@cornell.edu>.

2014-03-04  YAMAMOTO Mitsuharu  <mituharu@math.s.chiba-u.ac.jp>

	* xterm.c (x_draw_stretch_glyph_string): Reset clipping.
	(Bug#16932)

2014-03-04  Michal Nazarewicz  <mina86@mina86.com>

	* cmds.c (delete-char): Update docstring pointing out that the
	function ignores `delete-active-region' and `overwrite-mode'.

2014-03-03  Eli Zaretskii  <eliz@gnu.org>

	* font.c (Fframe_font_cache): Fix last change.  (Bug#16930)

	* gmalloc.c (aligned_alloc): Fix adjustment of size of the
	allocated buffer due to alignment.
	(freehook): If the block to be freed was allocated by
	'aligned_alloc', find its real pointer before calling 'free'.
	(Bug#16901)
	(mabort) [emacs]: Call 'emacs_abort', not 'abort', to provide a
	backtrace.

2014-03-03  Dmitry Antipov  <dmantipov@yandex.ru>

	* font.c (toplevel): Adjust comment about font cache layout.
	(font_clear_cache): Fix to match real font cache layout.
	Suggested by <namespace_collision@yahoo.com> in Bug#16069.
	(Fframe_font_cache) [FONT_DEBUG]: New function.
	(syms_of_font) [FONT_DEBUG]: Defsubr it.

	Avoid crashes when X fonts are erroneously freed on reused X
	'Display *' connection data (Bug#16069).  Note that X font
	resources still may be leaked, but currently there is no way
	to completely avoid it.
	* xterm.h (struct x_display_info): New member x_id.  Add comments.
	* xterm.c (x_display_id): New variable.
	(x_term_init): Assign identifier to each opened X connection.
	* xfont.c (struct xfont): New member x_display_id.
	(xfont_open): Initialize it with frame's display id.
	(xfont_close): Check whether font's display id matches the one
	recorded for the given display.  Adjust comment.
	* xftfont.c (struct xftfont_info):
	(xftfont_open, xftfont_close): Exactly as above with xfont stuff.

2014-03-01  Martin Rudalics  <rudalics@gmx.at>

	Consider Vother_window_scroll_buffer valid iff it's a live buffer.
	* window.c (Fother_window_for_scrolling): Don't try to scroll a
	killed Vother_window_scroll_buffer.
	(Vother_window_scroll_buffer): Fix doc-string accordingly.

2014-03-01  Eli Zaretskii  <eliz@gnu.org>

	* fileio.c (Fexpand_file_name) [WINDOWSNT]: Don't treat file names
	that start with more than 2 slashes as UNCs.  (Bug#16751)

2014-02-28  Paul Eggert  <eggert@penguin.cs.ucla.edu>

	Fix a few crashes and leaks when cloning C strings.
	* alloc.c, lisp.h (dupstring): New function.
	* gtkutil.c (xg_get_font):
	* term.c (tty_default_color_capabilities):
	* xsettings.c (store_monospaced_changed)
	(store_font_name_changed, parse_settings)
	(read_and_apply_settings, init_gsettings, init_gconf): Use it.
	This avoids some unlikely crashes due to accessing freed storage,
	and avoids some minor memory leaks in the more-typical case.

2014-02-28  Martin Rudalics  <rudalics@gmx.at>

	* xdisp.c (note_mode_line_or_margin_highlight): Don't show drag
	cursor when modeline can't be dragged (Bug#16647).

2014-02-28  Glenn Morris  <rgm@gnu.org>

	* doc.c (Fsnarf_documentation): Snarf not-yet-bound variables
	from custom-delayed-init-variables.  (Bug#11565)

2014-02-27  Martin Rudalics  <rudalics@gmx.at>

	More fixes for mouse glyph calculations (Bug#16647).
	* window.c (coordinates_in_window): In intersection of
	horizontal and vertical window dividers prefer the horizontal
	one.  Add some extra parens to last fix.
	(window_relative_x_coord): Return x-coordinate for header and
	mode line too.
	* xdisp.c (remember_mouse_glyph): In text area don't extend
	glyph into mode line to show the vertical drag cursor there
	immediately.  Subdivide mouse glyphs in right fringes to show a
	horizontal drag cursor as soon as we enter the "grabbable width"
	portion.  Handle vertical border case separately.  Do not
	subdivide window divider areas.
	(note_mouse_highlight): On bottom divider of bottommost windows
	show vertical drag cursor only when the minibuffer window can be
	resized.

2014-02-27  Eli Zaretskii  <eliz@gnu.org>

	* xdisp.c (pop_it): Restore the it->face_box_p flag which could be
	reset by the face of the object just displayed.  See also bug#76.
	(get_next_display_element): If the string came from a display
	property, examine the box face attribute at it->position, not at
	it->current.pos, since the latter was not updated yet.  (Bug#16870)
	(handle_face_prop): Improve commentary.

2014-02-27  Michael Albinus  <michael.albinus@gmx.de>

	* dbusbind.c (Fdbus__init_bus, Qdbus__init_bus, Sdbus__init_bus):
	Rename from Fdbus_init_bus_1, Qdbus_init_bus_1, Sdbus_init_bus_1.

2014-02-26  Martin Rudalics  <rudalics@gmx.at>

	Fixes around Bug#16647.
	* xdisp.c (remember_mouse_glyph): Handle ON_RIGHT_DIVIDER and
	ON_BOTTOM_DIVIDER cases.
	* window.c (coordinates_in_window): Return ON_VERTICAL_BORDER
	only if the window has no right divider.
	(Fcoordinates_in_window_p): Fix doc-string.

2014-02-25  Juanma Barranquero  <lekktu@gmail.com>

	* lread.c (Funintern): Fix doc to match advertised calling convention.

2014-02-24  Daniel Colascione  <dancol@dancol.org>

	* keyboard.c (read_char): Close race that resulted in lost events.

2014-02-22  Glenn Morris  <rgm@gnu.org>

	* frame.c (frame-alpha-lower-limit, frame-resize-pixelwise):
	* window.c (window-resize-pixelwise): Doc fixes.

	* process.c (Finternal_default_process_filter)
	(Finternal_default_process_sentinel): Doc tweaks.

2014-02-21  Glenn Morris  <rgm@gnu.org>

	* process.c (Fprocess_buffer, Faccept_process_output)
	(Finternal_default_process_filter, Finternal_default_process_sentinel):
	Doc fixes.

2014-02-21  Martin Rudalics  <rudalics@gmx.at>

	* window.c (Fwindow_scroll_bar_width): New function.

2014-02-21  Paul Eggert  <eggert@cs.ucla.edu>

	Pacify GCC when configuring with --enable-gcc-warnings.
	* xdisp.c (move_it_in_display_line_to) [lint]:
	Initialize recently-added local.

2014-02-21  Daniel Colascione  <dancol@dancol.org>

	* dbusbind.c: Rename dbus-init-bus to dbus-init-bus-1.

2014-02-20  Eli Zaretskii  <eliz@gnu.org>

	* xdisp.c (init_iterator): Don't dereference a bogus face
	pointer.  (Bug#16819)
	(try_cursor_movement): Don't use cursor position if
	set_cursor_from_row failed to compute it.  This avoids assertion
	violations in MATRIX_ROW.
	(move_it_in_display_line_to): Save the iterator state in ppos_it
	only once per call.  Reimplement the method used to return to the
	best candidate position if all the positions found in display line
	are beyond TO_CHARPOS.  This cuts down the number of calls to
	bidi_shelve_cache, which moves a lot of stuff when lines are long
	and include bidirectional text.  (Bug#15555)

2014-02-20  Glenn Morris  <rgm@gnu.org>

	* data.c (Fdefalias): Doc fix.

2014-02-19  Eli Zaretskii  <eliz@gnu.org>

	* xdisp.c (display_line): Fix horizontal scrolling of large images
	when fringes are turned off.  This comes at a price of not
	displaying the truncation/continuation glyphs in this case.
	(Bug#16806)

	* image.c (x_create_x_image_and_pixmap) [HAVE_NTGUI]: If
	CreateDIBSection returns an error indication, zero out *ximg after
	destroying the image.  This avoids crashes in memory allocations
	due to the fact that some of the callers also call
	x_destroy_x_image, which will attempt to free an already free'd
	block of memory.

2014-02-18  Martin Rudalics  <rudalics@gmx.at>

	* widget.c (update_various_frame_slots): Don't set
	FRAME_PIXEL_HEIGHT and FRAME_PIXEL_WIDTH here (Bug#16736).

2014-02-18  Michael Albinus  <michael.albinus@gmx.de>

	* dbusbind.c (xd_close_bus): Apply proper check on busobj.

2014-02-17  Paul Eggert  <eggert@cs.ucla.edu>

	temacs --daemon fix (Bug#16599).
	* emacs.c (main): Initialize daemon_pipe[1] here ...
	(syms_of_emacs): ... instead of here.

2014-02-16  Anders Lindgern  <andlind@gmail.com>

	* nsterm.m (keyDown:): Check for normal key even if NSNumericPadKeyMask
	is set (Bug#16505).

2014-02-16  Daniel Colascione  <dancol@dancol.org>

	* dbusbind.c (xd_lisp_dbus_to_dbus): New function.
	(xd_get_connection_address): Use it.
	(xd_close_bus): Use xd_lisp_dbus_to_dbus to instead of
	xd_get_connection_address because the latter signals if the bus
	we're trying to close is already disconnected.

2014-02-13  Eli Zaretskii  <eliz@gnu.org>

	* w32proc.c (start_timer_thread): Pass a non-NULL pointer as last
	argument to CreateThread.  This avoids segfaults on Windows 9X.
	Reported by oslsachem <oslsachem@gmail.com>.

2014-02-13  Paul Eggert  <eggert@cs.ucla.edu>

	Fix subspace record bug on HP-UX 10.20 (Bug#16717).
	* unexhp9k800.c (unexec_error): New function, to simplify the code.
	(check_lseek): New function, to report lseek errors.
	(save_data_space, update_file_ptrs, read_header, write_header)
	(copy_file, copy_rest, unexec): Use these news functions.
	(update_file_ptrs): Don't assume wraparound behavior when
	converting a large size_t value to off_t.

2014-02-13  Dmitry Antipov  <dmantipov@yandex.ru>

	* composite.c (fill_gstring_header): Pass positions as C integers
	and move parameters checking to...
	(Fcomposition_get_gstring): ...this function.  Handle case when
	buffer positions are in reversed order and avoid crash (Bug#16739).
	Adjust docstring.
	* buffer.c (validate_region): Mention current buffer in error message.

2014-02-12  Marcus Karlsson  <mk@acc.umu.se>  (tiny change)

	* image.c (pbm_load): Set to NO_PIXMAP on error (Bug#16683).

2014-02-12  Lars Ingebrigtsen  <larsi@gnus.org>

	* buffer.c (syms_of_buffer): Doc clarification (bug#9981).

2014-02-11  Glenn Morris  <rgm@gnu.org>

	* nsfns.m (ns_display_info_for_name, Fx_open_connection):
	Replace refs to "OpenStep" in messages.

2014-02-10  Paul Eggert  <eggert@cs.ucla.edu>

	Avoid "." at end of error diagnostics.
	* cmds.c (Fself_insert_command): Reword and avoid "." at end.
	* font.c (Ffont_at):
	* nsfns.m (ns_display_info_for_name):
	* nsselect.m (Fx_own_selection_internal):
	* nsterm.m (performDragOperation:):
	Remove "." from end of diagnostic.

2014-02-10  Lars Ingebrigtsen  <larsi@gnus.org>

	* fns.c (Fmaphash): Say what `maphash' returns, since it may be
	unintuitive (bug#15824).
	(Fyes_or_no_p): Doc fix (bug#15456).

2014-02-10  Dmitry Antipov  <dmantipov@yandex.ru>

	* cmds.c (Fself_insert_command): Respect the width of EMACS_INT
	and avoid warning.
	* eval.c (call_debugger): When exiting the debugger, do not allow
	max_specpdl_size less than actual binding depth (Bug#16603).
	(syms_of_eval): Adjust docstring.

2014-02-09  Lars Ingebrigtsen  <larsi@gnus.org>

	* cmds.c (Fself_insert_command): Output a clearer error message on
	negative repetitions (bug#9476).

2014-02-08  Lars Ingebrigtsen  <larsi@gnus.org>

	* xdisp.c (syms_of_xdisp): Doc clarification (bug#15657).

	* keyboard.c (Frecursive_edit): Say more precicely how throwing
	`exit' works (bug#15865).

2014-02-07  Martin Rudalics  <rudalics@gmx.at>

	Constrain window box/body sizes and margin widths (Bug#16649).
	* xdisp.c (window_box_width): Don't return less than zero.

	UNICOWS.DLL which has their non-stub implementations.
	(maybe_load_unicows_dll): Assign addresses to these 2 function
	pointers after loading UNICOWS.DLL.

	of toolbar lines needed when they exceed the height of the root
	window.

	* xdisp.c (tool_bar_height): Use WINDOW_PIXEL_WIDTH to set up the
	iterator X limits, not FRAME_TOTAL_COLS, for consistency with what
	redisplay_tool_bar does.  Improve and fix commentary.
	(hscroll_window_tree): Don't assume w->cursor.vpos is within the
	limits of the glyph matrices.  (Bug#16051)
	(redisplay_tool_bar): Modify the tool-bar-lines frame parameter
	only when the new size is different from the old one, and the new
	size can be achieved given the frame height.
