* 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).
* display.texi (Temporary Displays): Say that
with-temp-buffer-window makes its buffer current.
* frames.texi (Size and Position): Describe new option
`frame-resize-pixelwise'. Rewrite descriptions of
`set-frame-size', `set-frame-height' and `set-frame-width'.
* frame.c (x_set_frame_parameters): Always calculate new sizes
pixelwise to avoid potential loss when rounding.
* window.el (fit-frame-to-buffer): Get maximum width from
display's width instead of height.
src/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>.
src/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.
src/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.
* window.c (Fother_window_for_scrolling): Check that
Vother_window_scroll_buffer is a buffer.
* window.el (fit-frame-to-buffer, fit-frame-to-buffer-margins):
Fix doc-strings.
(fit-frame-to-buffer): New argument ONLY. Remove dependency on
fit-frame-to-buffer variable. Fix doc-string.
(fit-window-to-buffer): Set ONLY argument in call of
fit-frame-to-buffer. Fix doc-string.
* frames.texi (Size and Position): Rewrite entries for
`fit-frame-to-buffer' and `fit-frame-to-buffer-margins'. Add
description for `fit-frame-to-buffer-sizes'.
* windows.texi (Resizing Windows): Add descriptions for
pixelwise resizing. Add entries for `window-resize-pixelwise'
and `fit-window-to-buffer-horizontally'. Rewrite
`fit-window-to-buffer' entry.
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.
* 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.
* window.el (window-min-height, window-min-width): Rewrite
doc-strings.
(window-body-size): Add PIXELWISE argument to make it consistent
with its callees.
* display.texi (Window Dividers): New section.
* frames.texi (Layout Parameters): Add right-divider-width and
bottom-divider-width.
* windows.texi (Window Sizes): Redraw schematic and rewrite its
description. Rewrite descriptions of `window-total-height',
`window-total-width', `window-total-size', `window-body-height',
`window-body-width' and `window-size-fixed'. Add descriptions
for `window-pixel-height', `window-pixel-width',
`window-min-height' and `window-min-width'. Remove description
of `window-size-fixed-p' moving part of it to that of
`window-size-fixed'.
(Resizing Windows): Mention dividers when talking about minimum
sizes.
src/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>.
Fixes: debbugs:16901
* lisp/simple.el (delete-forward-char): Mark as interactive-only.
* src/cmds.c (delete-char): Update docstring pointing out that the
function ignores `delete-active-region' and `overwrite-mode'.
src/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'.
(mabort) [emacs]: Call 'emacs_abort', not 'abort', to provide a
backtrace.
Fixes: debbugs:16901
'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.
(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.
* 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.
