* src/dispextern.h (reset_mouse_highlight): Fix coding style.
* src/xterm.c (xi_position_changed): New functions.
(xi_report_motion_window_clear, handle_one_xevent): Don't report
motion events if the pixel position did not actually change.
* src/xterm.h (struct xi_device_t): New fields
`last_motion_window', `last_motion_x' and `last_motion_y'.
* src/xterm.c (handle_one_xevent): If a window manager sends us
FocusIn and FocusOut with XSendEvent (they do that), don't
detect focus changes when XInput 2 is enabled. The X server
will tell us the actual truth if the focus really did change.
* src/buffer.h (struct buffer_text): New field.
(BUF_CHARS_UNCHANGED_MODIFIED, CHARS_UNCHANGED_MODIFIED): New macros.
* src/buffer.c (Fget_buffer_create): Initialize the new field.
* src/xdisp.c (mark_window_display_accurate_1): Set the new field.
(redisplay_window): Use it, together with CHARS_MODIFF, instead of
MODIFF and UNCHANGED_MODIFIED to decide whether to check for long
lines.
* src/pdumper.c (dump_buffer): Dump the new field.
These were announced as removed in Emacs 28.1 NEWS, but apparently
never actually deleted: only their obsoletion warning was removed.
So the warnings were reintroduced in Emacs 28.2, and we now actually
delete them here instead.
* src/process.c (Fset_process_filter_multibyte)
(Fprocess_filter_multibyte_p): Delete functions obsolete since
Emacs 23.
(syms_of_process): Delete corresponding defsubrs.
* lisp/subr.el (process-filter-multibyte-p)
(set-process-filter-multibyte): Delete obsoletion.
* lisp/erc/erc-dcc.el (erc-dcc-server): Don't use obsolete functions.
* doc/lispref/positions.texi (Text Lines): Document them
* lisp/emacs-lisp/shortdoc.el: Mention them, and also the
buffer/line predicates.
* src/editfns.c (bol): New function.
(Fbol): New defun.
(Fline_beginning_position): Use `bol'.
(eol): New function.
(Feol): New defun.
(Fline_end_position): Use `eol'.
* src/xterm.c (x_dnd_begin_drag_and_drop): Set DND devices to -1
if XI2 is not supported on the given display.
(x_query_pointer): Make wrapper around x_query_pointer_1.
(x_query_pointer_1): Split off most of x_query_pointer to this
function. Allow a specific client pointer to be specified.
(x_dnd_update_tooltip_now, x_dnd_update_state): Use
x_query_pointer_1 with the right device instead of
XQueryPointer.
Don't say that a value is a fixnum if small enough and a bignum
otherwise, because that is now how Lisp integers always work,
and we generally don't expose the fixnum/bignum difference to the user
unless really necessary.
* src/charset.c (Fencode_char):
* src/editfns.c (Fuser_uid, Fuser_real_uid, Fgroup_gid)
(Fgroup_real_gid, Femacs_pid):
* src/font.c (Ffont_variation_glyphs):
* src/process.c (Fprocess_id):
Edit doc strings.
* src/pgtkselect.c:
* src/xselect.c: Edit comments.
* src/xfns.c (setup_xi_event_mask): Stop selecting for device
hierarchy events.
* src/xterm.c (xi_select_hierarchy_events, x_term_init): Select
those here instead, on the default root window.
* src/fringe.c (large_circle_bits): New variable.
(standard_bitmaps): Add large_circle_bits.
* lisp/fringe.el (fringe-bitmaps): Add 'large-circle'.
(fringe-custom-set-bitmap): New function.
* lisp/cus-edit.el (widget-fringe-bitmap-prompt-value-history): New
variable.
(fringe-bitmap): New widget.
* lisp/bookmark.el (bookmark-set-fringe-mark): Obsolete in favor of...
(bookmark-fringe-mark): ... this.
(bookmark-fringe-mark): Rename this fringe bitmap to...
(bookmark-mark): ... and change it to look like a bookmark.
(bookmark-face): Don't set the ':background' of the face. Instead,
set ':distant-foreground'.
(bookmark--set-fringe-mark, bookmark--remove-fringe-mark)
(bookmark-store, bookmark--jump-via): Consult the
'bookmark-fringe-mark' option.
* doc/lispref/customize.texi (Simple Types): Document 'fringe-bitmap'
type.
* doc/lispref/display.texi (Fringe Bitmaps): Mention 'large-circle'.
* etc/NEWS: Announce this change (bug#56896).
This fixes bug #57179.
* src/keyboard.c (safe_run_hooks_1, safe_run_hook_funcall): Enhance these
functions so that nargs == 3 or 4 is handled as well as nargs == 2. This
allows them to be used to call hooks with 1 or 2 arguments.
* src/coding.c (encode_coding_object): Mark saved_pt_byte with UNINIT
to silence a false alarm from -Wmaybe-uninitialized. This was already
done in decode_coding_object. The fix is correct because saved_pt is
used as a sentinel before saved_pt_byte is used (bug#57219).
* src/timefns.c (decode_lisp_time) [FASTER_TIMEFNS]:
Speed up when SPECIFIED_TIME is an integer.
(time_cmp) [FASTER_TIMEFNS]: Speed up when comparing integers.
* src/xterm.c (x_preserve_selections) [USE_XCB]: Fix bug: use of
wrong ‘tem’ value. Found by GCC -Wanalyzer-use-of-uninitialized-value.
Move decl of local to make the (former) bug more obvious.
* src/xdisp.c (mode_line_update_needed, redisplay_window)
(decode_mode_spec): Don't avoid calling current_column, as it is
now fast enough.
(redisplay_window) <optional_new_start>: Don't call 'move_it_to'
if its result will not be used.
(Flong_line_optimizations_p): New primitive.
* src/indent.c (Fcurrent_column): Doc fix.
(current_column, scan_for_column): When in a buffer with long
and/or truncated lines, quickly return an approximate value.
* src/window.c (Frecenter): Use the old text-mode code when the
buffer has very long lines.
* lisp/simple.el (line-move): Avoid costly calls to
'line-move-partial' and 'line-move-visual' when lines are
truncated and/or very long.
(move-beginning-of-line): Call 'line-beginning-position' instead
of the slower 'skip-chars-backward'.
* etc/NEWS: Announce 'long-line-optimizations-p'.
