* 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.
* frames.texi (Size and Position): In `frame-resize-pixelwise'
description drop remark about frame maximization.
* windows.texi (Display Action Functions): Add description for
`display-buffer-no-window' and explain use of `allow-no-window'
alist entries.
the docstring of functions advised before dumping.
* src/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.
Fixes: debbugs:16993
* doc/lispref/numbers.texi (Numeric Conversions, Rounding Operations):
Document that 'round' and 'fround' round to even.
* src/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.
src/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.
* 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.
