* src/dispextern.h: Declare image_prune_animation_caches for use
in gc.
* src/image.c (Fclear_image_cache): Clear animation cache.
(anim_prune_animation_cache, anim_get_animation_cache): Allow
clearing in addition to pruning.
(imagemagick_prune_animation_cache)
(imagemagick_get_animation_cache): Ditto.
(image_prune_animation_caches): New function (bug#56546).
* src/frame.c (delete_frame): Bind `x-auto-preserve-selections'
to nil if deleting display.
* src/xselect.c (x_clear_frame_selections): Pass original frame
to that function.
* src/xterm.c (x_preserve_selections): Fix determining the new
owner.
(syms_of_xterm): New defsym `x-auto-preserve-selections'.
* src/xterm.h: Update prototypes.
* src/buffer.c (Fmake_indirect_buffer): Kill the local
buffer-stale-function variable instead of setting it
buffer-locally to the default value. This should have the same
effect, but is less confusing.
This fixes bug #56502. That function and these variables were manipulated by
the former file emacs-lisp/lmenu.el that was finally expunged from directory
obsolete/ by Stefan Kangas on 2020-05-15. There remain references to them in
the *.c, and *.m files.
* src/keyboard.c (syms_of_keyboard): Remove declarations of the symbol and
variable.
* src/haikumenu.c (set_frame_menu_bar)
* src/keyboard.c (command_loop_1)
* src/nsmenu.m (ns_update_menubar)
* src/pgtkmenu.c (set_frame_menubar)
* src/xdisp.c (update_menu_bar)
* src/xmenu.c (set_frame_menubar): Remove calls to Qrecompute_lucid_menubar
contitional on Vlucid_menu_bar_dirty_flag.
* src/minibuf.c (minibuf_conform_representation): Remove.
(Ftry_completion): Don't call it.
(Ftest_completion): Don't use the obsolete Fstring_make_unibyte or
Fstring_make_multibyte; they don't serve any useful purpose here.
We don't try to equate unibyte and multibyte raw bytes in symbol
lookups elsewhere and there is no reason to do it here.
* lisp/subr.el (y-or-n-p): Enable commands that call this function
to be repeatable (bug#45999). This stopped working after this
function started using read-from-minibuffer.
* src/fns.c (Fyes_or_no_p): Ditto.
* etc/NEWS: Announce new hook `post-select-region-hook'.
* lisp/select.el (lost-selection-last-region-buffer): New
variable.
(lost-selection-post-select-region-function): New function.
Deactivate the mark if the buffer changed.
(lost-selection-mode): Add new hook.
* src/keyboard.c (command_loop_1): Run that hook when
appropriate.
(syms_of_keyboard): New hook `post-select-region-hook'.
* src/nsterm.h (struct ns_output): New fields to store the relief
colors.
* src/nsterm.m (ns_setup_relief_colors): New function to keep the
relief colors as part of the ns_output structure.
(ns_draw_relief): Remove static local variables. Assigning them to
nil caused a memory leak of NSColor instances (bug#56462). Call
ns_setup_relief_colors instead.
* src/character.h (str_to_multibyte):
* src/character.c (str_to_multibyte): Change signature and simplify;
the conversion is no longer done in-place.
* src/fns.c (string_to_multibyte): Drop temporary buffer and memcpy;
adapt to new str_to_multibyte signature.
* src/print.c (print_string): Drop memcpy; adapt call to str_to_multibyte.
* test/src/fns-tests.el (fns--string-to-unibyte): Rename to...
(fns--string-to-unibyte-multibyte): ... this and strengthen, so that
the test covers string-to-multibyte reasonably well.
* src/lisp.h (STRING_SET_MULTIBYTE): Make it into a function.
* src/composite.c (Fcomposition_get_gstring):
Prefer `make_multibyte_string` over Fconcat+STRING_SET_MULTIBYTE.
* src/xselect.c (x_handle_selection_request): Use
display-specific pending DND time.
(x_set_pending_dnd_time): Delete function.
* src/xterm.c (x_dnd_do_unsupported_drop, handle_one_xevent):
Set dpyinfo->pending_dnd_time instead.
* src/xterm.h (struct x_display_info): New field
`pending_dnd_time'. Make handling pending drops
display-specific to avoid interference when there are multiple
displays.
* src/haiku_select.cc (be_handle_clipboard_changed_message):
Include current clipboard count.
(be_selection_outdated_p): New function.
* src/haikuselect.c (haiku_handle_selection_clear): Ignore
outdated events.
(haiku_selection_disowned): New argument `count'. Include it in
the timestamp field of the selection clear event.
* src/haikuselect.h: Update prototypes.
* src/systime.h: Define `Time' to an appropriate value on Haiku.
* src/xterm.c (handle_one_xevent): Clear net_supported_window if
it is destroyed.
(x_get_wm_check_window): New function.
(x_wm_supports_1): First try net_supported_window. If it still
exists, don't ask for _NET_SUPPORTING_WM_CHECK.
Don't crash if the file name argument to file-name-case-insensitive-p,
after expansion, doesn't have a parent directory. This occurs
when calling ffap on something that looks like an email address.
* src/fileio.c (Ffile_name_case_insensitive_p): Return nil if no file
or parent directory could be found.
* test/src/fileio-tests.el (fileio-tests--identity-expand-handler)
(fileio--file-name-case-insensitive-p): New test.
* src/xterm.c (x_set_frame_alpha): Don't synchronize while
setting alpha property, and don't ask for the current value of
the opacity property, which is much more expensive than changing
it.
