* 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.
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.
src/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.
(handle_face_prop): Improve commentary.
* 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.
* src/frame.c (frame-alpha-lower-limit, frame-resize-pixelwise):
* src/window.c (window-resize-pixelwise): Doc fixes.
* etc/NEWS: Related edits.
This including unmarking some items marked as ---, where it it not
clear to me that no doc updates are needed.
* window.el (window--dump-window, window--dump-frame): New
functions.
(window--min-size-1): Account for window dividers. When
window-resize-pixelwise is nil, delay rounding till after the
sum of the window components has been calculated.
(window--min-delta-1, window--max-delta-1): When PIXELWISE is
nil make sure at least one text line and two text columns remain
fully visible.
(window-resize): Signal an error when window-resize-apply fails.
(window--resize-child-windows): Fix calculation of by how many
pixels a window can still be shrunk via window-new-normal.
(adjust-window-trailing-edge): Call window--resizable with
correct TRAIL argument.
src/xdisp.c (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.
src/xdisp.c (try_cursor_movement): Don't use cursor position if
set_cursor_from_row failed to compute it. This avoids assertion
violations in MATRIX_ROW.
src/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.
src/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.
src/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>.
* 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.
Fixes: debbugs:16717
and move parameters checking to...
* composite.c (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.
