* src/fns.c (Frequire):
* src/eval.c (Fautoload_do_load): Avoid further errors while
outputting the error about not being able to autoload/require
while bootstrapping.
This allows abandoning the redisplay of a window
that takes too long to complete. Bug#45898
* src/xdisp.c (update_redisplay_ticks): New function.
(init_iterator, set_iterator_to_next): Call
'update_redisplay_ticks'.
(syms_of_xdisp) <max_redisplay_ticks>: New variable.
<list_of_error>: Remove 'void-variable': it is no longer needed,
since 'calc_pixel_width_or_height' can no longer signal a
void-variable error, and it gets in the way of aborting
redisplay via 'redisplay_window_error'.
* src/keyboard.c (command_loop_1): Reinitialize the tick count
before executing each command in the loop.
* src/syntax.c (scan_sexps_forward): Call 'update_redisplay_ticks'
after finishing the loop.
* src/dispnew.c (make_current): Make sure enabled rows of the
current matrix have a valid hash, even if redisplay of a window
was aborted due to slowness. This avoids assertion violations in
'scrolling_window' due to the wrong hash value.
* src/xdisp.c (display_working_on_window_p): New global variable.
(unwind_display_working_on_window): New function.
* src/keyboard.c (command_loop_1): Reset
'display_working_on_window_p' before and after executing commands.
* src/window.c (Frecenter, window_scroll, displayed_window_lines):
* src/indent.c (Fvertical_motion): Set
'display_working_on_window_p' before calling 'start_display'.
* src/syntax.c (scan_sexps_forward): Call 'update_redisplay_ticks'
after finishing the loop.
* src/regex-emacs.c (re_match_2_internal):
* src/bidi.c (bidi_find_bracket_pairs, bidi_fetch_char)
(bidi_paragraph_init, bidi_find_other_level_edge): Update the
redisplay tick count as appropriate, when moving the iterator by
one character position actually requires to examine many more
positions.
* src/xdisp.c (redisplay_window_error): Show messages about
aborted redisplay of a window as delayed-warnings.
* doc/emacs/trouble.texi (DEL Does Not Delete): Move to the end of
the chapter. This issue is no longer frequent or important as it
was back in Emacs 20 days.
(Long Lines): Document 'max-redisplay-ticks'.
* doc/emacs/emacs.texi (Top): Update the detailed menu.
* etc/NEWS: Announce 'max-redisplay-ticks'.
* src/xterm.c (xi_convert_button_state, xi_convert_event_state):

FSPEC_ANTIALIAS.
(Fx_select_font): Update accordingly.

(x_defer_selection_requests): Set input_pending if the kbd
buffer was modified.
(x_delete_selection_requests): New function.
(x_delete_display): Call that. Bug found when a display died
while the clipboard manager was sending an unreasonably high
number of requests.

`with-delayed-message' here.

(x_get_foreign_selection): Add an atimer that displays the
message after a while.
* src/emacs.c (load_pdump): Don't overwrite the leading
directories of the Emacs executable just because the pdumper file
was not found in the expected directory relative to the binary.
This is needed to support builds with a separate --bindir
configure-time option and native-compilation. (Bug#55741)
* src/process.c (wait_reading_process_output): Don't allow
skipping calls to select if detect_input_pending when just

(syms_of_haikufont): Call it in a pdumper hook.
* src/xterm.c (handle_one_xevent): Set the last user time if a
button press happens during drag and drop. Mysterious problems
were other seen with sending selections to a clipboard
immediately afterwards on Irix 6.5.
* src/xdisp.c (update_redisplay_ticks): Don't disable redisplay of
mini-windows.
* src/regex-emacs.c (re_match_2_internal):
* src/bidi.c (bidi_find_bracket_pairs, bidi_fetch_char)
(bidi_paragraph_init, bidi_find_other_level_edge): Update the
redisplay tick count as appropriate, when moving the iterator by
one character position actually requires to examine many more
positions.

recommended non-zero values.
* src/xterm.c (xm_get_drag_window_1): New function.

just return it.
(xm_setup_dnd_targets): If a BadWindow error occurs, re-create
the Motif drag window.
* src/xterm.h (struct x_display_info): New field
`motif_drag_window'.

response to entering the return-frame.
* lisp/frame.el (tty-select-active-regions): Pacify warning about
missing defcustom :group by specifying the same group as
select-active-regions, as well as the frames group.

occurrences of xterm-select-active-regions to

as not being keys (bug#55940).
* src/keymap.c (Fwhere_is_internal): Filter out key sequences that
are marked as being non-keys.
This allows Emacs to save the active region to the user's
primary selection on supported terminals. The behavior follows
the existing `select-active-regions' variable and requires
`xterm-select-active-regions' to be non-nil.
* src/keyboard.c (command_loop_1):
* lisp/frame.el (display-selections-p): On text terminals, check
terminal parameter `xterm--set-selections' and variable
`xterm-select-active-regions' when deciding whether to update
primary selection. (bug#55883)
* lisp/term/xterm.el (xterm-select-active-regions): New
defcustom.
