The toolkit can send far too many resize notifications, so be more
careful when we take action after receiving one.
* src/nsfns.m (ns_set_tool_bar_lines): Remove unneeded NSTRACE.
* src/nsterm.m ([EmacsView viewDidResize:]): Don't report resizes to
Emacs when the same change has already been reported and delayed.
The purpose of this change is to have implied frame size changes
pick up sizes requested by previous explicit size changes not
only after they have been confirmed by the WM but already when
they are initially passed to adjust_frame_size (Bug#17120).
* src/dispextern.h (delayed_size_change): Remove extern.
* src/dispnew.c (delayed_size_change): Make static again.
(do_pending_window_change): Call change_frame_size only if F's
new_size_p flag is set.
(change_frame_size_1): Set/reset F's new_size_p flag
* src/frame.c (adjust_frame_size): Remove extra
inhibit_horizontal/_vertical checks. Improve the implied
resizes check with INHIBIT equals 2. Set F's new_width and
new_height and reset F's new_size_p flag when we run
set_window_size_hook with INHIBIT 0 or 1.
* src/frame.h (struct frame): New bit slot new_size_p.
* src/gtkutil.c (xg_frame_resized): Use F's new_size_p flag
instead of delayed_size_change to decide whether to call
change_frame_size.
(xg_frame_set_char_size): Call frame_size_history_extra before
waiting for the ConfigureNotify event.
* src/xterm.c (handle_one_xevent): Use F's new_size_p flag
instead of delayed_size_change to decide whether to call
change_frame_size.
Have adjust_frame_size pass native frame sizes to backends
instead of text sizes. Expand frame size history management.
Drop PIXELWISE argument from change_frame_size and convert
native to text sizes only when calling adjust_frame_size. Use
convention in arguments that -1 instead of 0 means that no size
change is required. When adjusting frame sizes pick up delayed
size changes (Bug#46827).
* lisp/frame.el (frame-notice-user-settings, make-frame): Don't
set frame size history.
(frame--size-history): Rewrite doc-string. Handle new formats
of `frame-size-history' entries.
* src/dispextern.h (delayed_size_change): Extern it.
(change_frame_size): Drop last argument from extern.
* src/dispnew.c (delayed_size_change): Make it global.
(handle_window_change_signal): Reformat. Drop last argument
from change_frame_size call.
(do_pending_window_change, init_display_interactive): Drop last
argument from change_frame_size call.
(change_frame_size_1): NEW_WIDTH and NEW_HEIGHT now specify
native sizes. Drop last argument PIXELWISE. Queue a change
when it either differs from F's current pixel sizes or F's
previously queued sizes. Inject frame_size_history_extra call
when queuing. Adopt convention that for queued sizes -1 means
that no size change is required. Convert from native to text
sizes when calling adjust_frame_size.
(change_frame_size): Drop last argument PIXELWISE and drop it
also in change_frame_size_1 calls.
* src/frame.c (frame_size_history_add): Remove.
(frame_inhibit_resize): Remove call to frame_size_history_add.
(set_menu_bar_lines, set_tab_bar_lines): Simplify. Drop last
argument from change_frame_size call.
(frame_windows_min_size): No more static.
(keep_ratio): Minor rewrite using macros.
(frame_size_history_adjust, frame_size_history_plain)
(frame_size_history_extra): New functions.
(adjust_frame_size): Major rewrite. Adopt new convention that
negative values for new sizes mean no change. Pick up delayed
size changes from F's new_width and new_height slots
(Bug#46827). Call set_window_size_hook with native instead of
text sizes. Do not sanitize window sizes any more. Call
frame_size_history_adjust instead of frame_size_history_add.
Always set F's resized_p slot to true.
(make_frame): Initialize new_width and new_height slots to -1.
Simplify setup of initial sizes and an adjust_frame_size call.
(Fframe_parameters): Drop processing F's new_pixelwise slot.
(check_frame_pixels): Reorder to make declarations appear first.
(Fset_frame_height, Fset_frame_width, Fset_frame_size): Pass
explicit width and height values to adjust_frame_size instead of
-1.
(gui_set_frame_parameters): Minor rewrite making sure that
explicit sizes and the corresponding parameter are passed to
adjust_frame_size. Remove frame_size_history_add call.
(gui_figure_window_size): Drop last two arguments. Simplify
assignment of initial size. Set new_height and new_width slots
to -1. Use adjust_frame_size to set sizes instead of returning
them to caller.
(syms_of_frame): Drop symbols used by frame size history; these
are now built on-the-fly. Also drop some menu bar related
symbols in favor of Qmenu_bar_lines.
* src/frame.h (struct frame): Remove new_pixelwise.
(SET_FRAME_COLS, SET_FRAME_LINES, SET_FRAME_WIDTH)
(SET_FRAME_HEIGHT): Remove macros.
(frame_size_history_add): Remove externs.
(frame_windows_min_size, frame_size_history_plain)
(frame_size_history_extra): Add externs.
(FRAME_WINDOWS_WIDTH, FRAME_WINDOWS_HEIGHT): Rename to
FRAME_INNER_WIDTH and FRAME_INNER_HEIGHT.
(gui_figure_window_size): Drop last two arguments from
extern.
* src/gtkutil.c (xg_frame_resized): Rename arguments to WIDTH
and HEIGHT. Consult delayed_size_change to handle case where
WIDTH and HEIGHT do not match F's new_width and new_height
values. Call change_frame_size with native sizes and without
PIXELWISE argument. Instead of frame_size_history_add call
frame_size_history_extra.
(xg_frame_set_char_size): WIDTH and HEIGHT are native sizes now;
fix adjust_frame_size call accordingly. Instead of
frame_size_history_add call frame_size_history_extra.
(style_changed_cb): Call xg_frame_set_char_size with native
instead of text sizes.
(tb_size_cb): Remove frame_size_history_add call. Call
adjust_frame_size with INHIBIT 5.
(free_frame_tool_bar, xg_change_toolbar_position): Remove
frame_size_history_add call.
(update_frame_tool_bar): Call adjust_frame_size with INHIBIT 2
and let it handle frame_inhibit_implied_resize and
fullheight/-width. Remove frame_size_history_add call.
* src/keyboard.c (Fsuspend_emacs): Call change_frame_size with
native sizes.
* src/nsfns.m (ns_set_tool_bar_lines): Call adjust_frame_size
with INHIBIT 2 and let it handle frame_inhibit_implied_resize
and fullheight/-width. Remove frame_size_history_add call.
(Fx_create_frame): Drop two last arguments in
gui_figure_window_size call. Do not SET_FRAME_WIDTH and
SET_FRAME_HEIGHT, the adjust_frame_size in
gui_figure_window_size did that already.
* src/nsterm.m (ns_set_window_size): Drop PIXELWISE argument and
its processing; WIDTH and HEIGHT represent native pixel sizes
now. Call change_frame_size with native sizes. Remove call to
frame_size_history_add.
([EmacsView viewDidResize:]): Call change_frame_size with native
sizes.
* src/term.c (Fresume_tty): Call change_frame_size with native
sizes.
* src/termhooks.h (*set_window_size_hook): Drop last argument
PIXELWISE.
* src/w32fns.c (w32_change_tab_bar_height)
(w32_change_tool_bar_height): Fix handling of these in the initial
phase before they have been resized at least once.
(Fx_create_frame, w32_create_tip_frame): Drop two last arguments
in gui_figure_window_size call. Do not SET_FRAME_WIDTH and
SET_FRAME_HEIGHT (or SET_FRAME_COLS and SET_FRAME_LINES), the
adjust_frame_size in gui_figure_window_size did that already.
* src/w32inevt.c (resize_event, maybe_generate_resize_event):
Pass native sizes to change_frame_size.
* src/w32term.c (w32_read_socket): When WM_WINDOWPOSCHANGED pass
native sizes to change_frame_size.

code.
(w32fullscreen_hook): Call change_frame_size with native sizes.
(w32_set_window_size): Drop argument PIXELWISE and its
processing; WIDTH and HEIGHT are native sizes now. Remove
frame_size_history_add calls. Pass native sizes to
change_frame_size.
* src/widget.c (set_frame_size): Set width and height of widget
directly. Call frame_size_history_plain instead of
frame_size_history_add.
(update_from_various_frame_slots): Call
frame_size_history_extra.
(EmacsFrameRealize): Call frame_size_history_plain.
(EmacsFrameResize): Call change_frame_size with native sizes.
Call frame_size_history_extra instead of frame_size_history_add.
(EmacsFrameSetCharSize): Call frame_size_history_extra. Drop
PIXELWISE argument in x_set_window_size call and specify pixels.
(pixel_to_text_size): Remove function.
* src/xdisp.c (resize_mini_window): Replace FRAME_WINDOWS_HEIGHT
with FRAME_INNER_HEIGHT.
(redisplay_tab_bar): Don't set tab_bar_redisplayed when we did
not redisplay it.
(redisplay_tool_bar): Don't call it for external tool bar.
Don't set tool_bar_redisplayed when we did not redisplay it.
(redisplay_window): When the tool bar is external call
update_frame_tool_bar directly.
* src/xfns.c (x_set_menu_bar_lines): Call adjust_frame_size only
if number of menu bar lines changed and fix 6th argument.
(x_change_tab_bar_height, x_change_tool_bar_height): Fix
handling of these in the initial phase before they have been
resized at least once.
(Fx_create_frame, x_create_tip_frame): Drop two last arguments
in gui_figure_window_size call. Do not SET_FRAME_WIDTH and
SET_FRAME_HEIGHT (or SET_FRAME_COLS and SET_FRAME_LINES), the
adjust_frame_size in gui_figure_window_size did that already.
* src/xmenu.c (update_frame_menubar): Fix 6th arg of
adjust_frame_size call.
(free_frame_menubar): For Motif frames fix fullscreen and
`frame-inhibit-implied-resize' handling. Fix 6th arg of
adjust_frame_size calls.
* src/xterm.c (x_net_wm_state): Remove call to
frame_size_history_add.
(handle_one_xevent): For PropertyNotify and UnmapNotify events
add frame_size_history_plain calls. For MapNotify and
ConfigureNotify events add a frame_size_history_extra call. For
ConfigureNotify events also handle delayed size changes and call
change_frame_size with native sizes.

(x_handle_net_wm_state): Remove frame_size_history_add call.
(x_check_fullscreen): Remove frame_size_history_add call. Call
change_frame_size with native height.
(x_set_window_size_1): WIDTH and HEIGHT are now native. Remove
some frame_size_history_add calls and add frame_size_history_extra
calls instead. If the frame is not visible call adjust_frame_size
directly instead of calling change_frame_size.
(x_set_window_size): Drop PIXELWISE argument. WIDTH and HEIGHT
represent native sizes now.
(x_make_frame_visible, x_make_frame_invisible): Call
frame_size_history_plain.
* src/xterm.h (x_set_window_size): Drop last argument from
extern declaration.
* src/xterm.c (x_create_toolkit_scroll_bar)
(x_create_horizontal_toolkit_scroll_bar): String constants for
XtSetArg are defined as const strings (in
/usr/include/X11/Xaw3d/ThreeD.h, for instance), but the argument
in XtSetArg is defined as either a const char* or a regular char*
in /usr/include/X11/Intrinsic.h. Cast the argument to String
(which should be correct on all platforms, hopefully) to avoid a
compilation warning (bug#47452).
Also fix a bug where, with minibuffer-follows-selected-frame neither nil nor
t, a minibuffer could appear in two frames at the same time.
* src/window.c (Fset_window_configuration): Add a new &optional parameter
DONT-SET-MINIWINDOW, which inhibits the minibuffer from being restored from
the supplied window configuration.
(restore_window_configuration): Enhance to match the above.
* src/minibuf.c (read_minibuf): Enhance the argument list to the
restore_window_configuration calls to match the above. In the main case,
restoring the minibuffer is inhibited.
(read_minibuf_unwind): Should the frame with the expired minibuffer not be
found ("can't happen"), unwind the stacked data nevertheless, rather than just
exiting.
* src/keyboard.c (read_char_help_form_unwind): Amend a call of
Fset_window_configuration.
* doc/lispref/windows.texi (Window Configurations): Document the new form of
set-window-configuration.
* etc/NEWS (Lisp Changes in Emacs 28.1): Amend the entry for
set-window-configuration.
We used to `bset_enable_multibyte_characters` while the buffer is not
empty, putting the buffer temporarily in an inconsistent state.
Further simplifications along the way: Prefer re-using local var `histvar`
and let `insert` do the unibyte<->multibyte conversion if needed.
* lisp/minibuffer.el (minibuffer-mode): New derived mode.
* src/minibuf.c (syms_of_minibuf): New DEFSYMs Qminibuffer_mode,
Qminibuffer_inactive_mode, Qminibuffer_completing_file_name,
Qselect_frame_set_input_focus, Qadd_to_history.
(read_minibuf, set_minibuffer_mode, read_minibuf_unwind): Use the new DEFSYMs
in place of continual interning.
(set_minibuffer_mode): Put an active minibuffer into minibuffer-mode rather
than fundamental-mode.
* doc/emacs/mini.texi (Minibuffer Edit): Mention minibuffer-mode.
* doc/lispref/minibuf.texi (Intro to Minibuffers): Add a paragraph about
minibuffer-mode.
* etc/NEWS (Incompatible Lisp Changes in Emacs 28.1): Add an entry.
* src/frame.c (do_switch_frame): Don't switch to a tooltip frame.
(Fselect_frame): Do not select a tooltip frame.
* src/w32fns.c (Fx_show_tip):
* src/xfns.c (Fx_show_tip): Set the tooltip window's
`no-other-window' parameter so `other-window' will skip it.
* src/window.c (select_window): Do not select a tooltip window.
(candidate_window_p): Make sure MINIBUF is live.
(decode_next_window_args): Make sure that W's frame's minibuffer
window is live before including it.
(Qno_other_window): New symbol.
* src/emacs.c (real_filename, set_invocation_vars)
(init_vars_for_load): Functions deleted; callers adjusted.
(init_cmdargs): Put back all the code which was extracted into
set_invocation_vars.
(load_pdump_find_executable): Make sure the return value has any
symlinks in it expanded.
(load_pdump): Accept only 2 arguments, not 3. Determine both the
file name of the Emacs executable and of the dump file in
synchronized manner, so that if we decided to look for the dump
file in its hardcoded installation directory, the directory of the
Emacs executable will also be where we expect it to be installed.
Pass only 2 arguments to pdumper_load. (Bug#47800) (Bug#44128)
* src/pdumper.c (dump_do_dump_relocation): Use emacs_execdir
instead of Vinvocation_directory to produce absolute file names of
*.eln files that are recorded in the pdumper file. Pass the full
.eln file name to fixup_eln_load_path.
(pdumper_set_emacs_execdir) [HAVE_NATIVE_COMP]: New function.
(pdumper_load) [HAVE_NATIVE_COMP]: Call pdumper_set_emacs_execdir.
* src/comp.c (fixup_eln_load_path): Use Fsubstring_no_properties
instead of Fsubstring. No need to cons a file name, as the caller
already did that. Use explicit const string to avoid "magic"
values.
* lisp/startup.el (normal-top-level): Use expand-file-name instead
of concat. Decode comp-eln-load-path and expand-file-name its
members.
This partly fixes bug #47207.
* src/minibuf.c (choose_minibuf_frame, move_minibuffers_onto_frame)
(read_minibuf (twice), read_minibuf_unwind): Before using a frame's
->minibuffer_window field, check it is valid with WINDOW_LIVE_P.
(choose_minibuf_frame): Remove the emacs_abort for a null minibuffer.
* src/image.c (image_get_dimension): New function.
(compute_image_size): Use image_get_dimension to set the sizes, and
pass in the image struct instead of just the spec.
(image_set_transform):
(imagemagick_load_image):
(svg_load_image): Use the image instead of the spec in compute_image_size.
(syms_of_image): Add 'em' as a symbol.
Allow a condition-case handler on the form (:success BODY) to be
specified as the success continuation of the protected form, with
the specified variable bound to its result.
* src/eval.c (Fcondition_case): Update the doc string.
(internal_lisp_condition_case): Implement in interpreter.
(syms_of_eval): Defsym :success.
* lisp/emacs-lisp/bytecomp.el (byte-compile-condition-case):
Implement in byte-compiler.
* lisp/emacs-lisp/cl-macs.el (cl--self-tco): Allow self-TCO
from success handler.
* doc/lispref/control.texi (Handling Errors): Update manual.
* etc/NEWS: Announce.
* test/lisp/emacs-lisp/bytecomp-tests.el (bytecomp-tests--test-cases)
(bytecomp-condition-case-success):
* test/lisp/emacs-lisp/cl-macs-tests.el (cl-macs--labels):
Add test cases.
* src/character.c (Fstring_width, lisp_string_width): Accept two
optional arguments FROM and TO, to indicate the substring to be
considered.
(Fstring_width): Add caveats in the doc string about display
features ignored by the function. (Bug#47712)
* src/character.h (lisp_string_width): Update prototype.
* src/editfns.c (styled_format): Adjust call of lisp_string_width
to its changed signature.
* test/src/character-tests.el (character-test-string-width): New
file with tests for 'string-width'.
* doc/lispref/display.texi (Size of Displayed Text): Document
caveats of using 'string-width'.
* etc/NEWS: Announce the change.
Move that function next to its siblings. Also simplify it, since
after careful analysis it is now clear that the frame's title's update
is already handled elsewhere (in `prepare_menu_bars` and `redisplay_window`)
so we just need to make sure the `redisplay` bit is set.
* src/window.c (wset_update_mode_line): Move to `src/xdisp.c`.
* src/window.h (wset_update_mode_line): Declare.
* src/w32term.c (w32_draw_image_relief): Support tab-bar drawing
with relief as xterm.c does.
* src/xdisp.c (handle_tab_bar_click): Access the mouse-highlight
info. Call show_mouse_face to show the button in the pressed or
the released state, according to value of DOWN_P.
(note_tab_bar_highlight): Function added back.
(note_mouse_highlight): Call note_tab_bar_highlight when the mouse
pointer is in the tab-bar window.
(show_mouse_face): Return immediately if mouse_face_window is not
set up in HLINFO. This avoids rare assertion violations.
