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/composite.c (find_automatic_composition): Don't use
narrowed_begv if it's zero. This avoids segfault in
BACKWARD_CHAR, since zero is not a valid buffer position.
* 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.
* src/dispextern.h (struct it): New 'narrowed_begv' field.
* src/dispextern.h (WITH_NARROWED_BEGV): New macro.
* src/xdisp.c (get_narrowed_begv): New function.
(init_iterator): Initilize the 'narrowed_begv' field.
(back_to_previous_line_start, get_visually_first_element,
move_it_vertically_backward): Use the new macro.
* src/dispextern.h: Prototype of 'get_narrowed_begv'.
* src/window.c (window_body_height): Make it externally visible.
* src/window.h: Prototype of 'window_body_height'.
* src/composite.c (find_automatic_composition): Optimize display in buffers
with very long lines with 'get_narrowed_begv'.
* lisp/obsolete/longlines.el: Reobsolete longlines-mode.
* etc/NEWS: Announce the new minor mode, and remove the unobsoletion
indication for 'longlines-mode'.
* doc/emacs/trouble.texi (Long Lines): Remove the section.
(Lossage): Remove the entry for the Long Lines section.
* doc/emacs/emacs.texi (Top): Remove the entry for the Long Lines section.
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.
By separating the code paths for append and vconcat, each becomes
simpler and faster.
* src/fns.c (concat_strings): Rename to...
(concat_to_string): ...this.
(concat): Split into concat_to_list and concat_to_vector.
(concat_to_list, concat_to_vector): New, specialised and
streamlined from earlier combined code.
(concat2, concat3, Fappend, Fconcat, Fvconcat): Adjust calls.
