Fix two problems with our handling of X timestamps
1) We're not properly updating the X interaction timestamp after
receiving certain input events, and
2) X events sent in response to emacsclient commands get stale
timestamps because the timestamp tracking doesn't take into account
that interactions with the user can occur outside the X input
event channel.

|
|
|
|
* src/xdisp.c (init_iterator): Always initialize narrowed_begv to
zero, since SET_WITH_NARROWED_BEGV depends on it being non-zero as
an indication that long-line optimizations are in use.
(back_to_previous_visible_line_start): When long-line
optimizations are in effect, we may end up not on a newline.
|
|
* src/Makefile.in (LC_ALL): Add loaddefs.el as a dependency, too,
since that file may be deleted, but the loaddefs.elc file still
exists. This causes problems in nativecomp builds.
|
|
* src/xmenu.c (x_menu_translate_generic_event, pop_down_menu):
Clear grab correctly on individual XI2 devices.
|
|
* etc/TODO: Document that MPX support still needs work.
* src/xterm.c (xi_handle_interaction): New function.
(handle_one_xevent): Call it in the appropriate places.
|
|
* src/xterm.c (x_cache_xi_devices): Initialize device fields to
0.
(xi_handle_focus_change, xi_focus_handle_for_device)
(xi_handle_delete_frame): New functions; store focus information
per-device instead.
(x_detect_focus_change): Handle GenericEvents that way instead.
(handle_one_xevent): Don't cache XI devices on DeviceChanged.
(x_free_frame_resources): Clear any frame focus information.

tracking. Add comments describing fields.

|
* src/composite.c (composition_compute_stop_pos): Use an 'endpos' that
is not too far away.
(find_automatic_composition): Use a 'head' that is not too far away.
Also make sure that this code path is not taken when long line
optimizations are disabled.
* src/dispextern.h (struct composition_it): Add a field that points
to the parent iterator.
* src/xdisp.c (init_iterator): Set it.
|
|
* configure.ac (HAVE_XSYNC): Also check for XSyncTriggerFence.
* src/xfns.c (Fx_create_frame): Create fences.
* src/xterm.c (x_atom_refs): New atom.
(x_sync_trigger_fence, x_sync_init_fences, x_sync_free_fences):
New functions.
(x_sync_update_finish): Trigger the appropriate fence.
(x_free_frame_resources): Free fences.
* src/xterm.h (struct x_display_info): New atom
`_NET_WM_SYNC_FENCES'.

|
|
* src/Makefile.in ($(etc)/DOC): Remove comment aboout make-docfile
being run twice (because it no longer is).
|
|
* src/xterm.c (xi_select_scroll_bar_events): New function.
(x_create_toolkit_scroll_bar)
(x_create_horizontal_toolkit_scroll_bar, x_scroll_bar_create):
Factor out input extension code there.
|
|
* src/lread.c (read_string_literal): Since we're now
byte-compiling the loaddefs files (so doc strings come from the
.elc files), remove the hack that make this return 0 when the
string starts with "\\n".
|
|
* Makefile.in (VCSWITNESS): Remove, since we're always rescanning
for loaddefs.
* src/Makefile.in ($(lispsource)/loaddefs.el): Remove VCSWITNESS
dependency.
|
|
* src/xterm.c (x_make_frame_visible): Keep track of whether or
not the output buffer was implictly flushed before issuing
XFlush.
|
|
* lisp/Makefile.in (all): Add "autoloads", which now otherwise
won't be done.
($(lisp)/loaddefs.el): Remove this target, since it's always done,
and would then trigger a re-compilation of loaddefs.elc.
* lisp/loadup.el: Load loaddefs.elc (if it exists).
* lisp/emacs-lisp/loaddefs-gen.el (loaddefs-generate): Don't
include no-byte-compile cookies in the Emacs build.
* src/Makefile.in ($(pdmp)): Depend on loaddefs.elc to ensure that
it's built by this point.
($(etc)/DOC): Don't scan loaddefs.el for doc strings, since they
are now picked up from the .elc file (bug#53024).
|
|
|
|
* src/xfns.c (x_set_background_color): Stop setting scroll bar
window background, since this is now taken care of
automatically.
|
|
* src/xterm.c (x_sync_get_monotonic_time): Use that if
available.
(x_display_set_last_user_time): Compute an offset between the
monotonic time and the X server time if they are not identical.

`server_time_offset'.
|
|

(x_sync_current_monotonic_time, x_sync_note_frame_times): New
functions.
(x_sync_wait_for_frame_drawn_event, x_sync_update_begin)
(x_sync_handle_frame_drawn): Note frame times.
(x_display_set_last_user_time): Check if the X server time is
probably the same as CLOCK_MONOTONIC.

fields and flags for clock handling and frame times.
|
|
* src/xterm.c (XFlush): Remove define to 0.
(x_clear_frame, x_scroll_run, x_draw_window_cursor)
(x_free_frame_resources): Remove calls to XFlush where it is not
really necessary. Leave the calls that actually are intact.
|
|
|
|

events for ConfigureNotify events bound for the root window.
|
|
* src/xterm.c (x_find_monitors_changed_event): New function.
(x_monitors_changed_cb, handle_one_xevent): Look through the
entire event queue to skip delivering monitor change events.
|
|
* src/editfns.c (narrow_to_region_internal): New function, which
contains the body previously in 'Fnarrow_to_region' but accepts
a third argument.
(Fnarrow_to_region): Use the new function. Update the docstring.
(Fwiden): Update the docstring.
* src/lisp.h: Prototype of the new function.

* src/lread.c (readevalloop): Remove the third argument to
'Fnarrow_to_region'.
* src/bytecode.c (exec_byte_code):

field.
