- Add several autoload cookies.
- Separate public API hook used internally into a private hook.
- Fix thinko in setting up the special event sleep-event handler.
- Probe the D-Bus session bus for screen saver support during
enable.
* lisp/system-sleep.el (system-sleep--set-back-end): Move dbus
endpoint tests into the system-sleep--enable dbus
implementation.
(system-sleep--event-after-hook-functions): New private hook.
(system-sleep--dbus-has-screensaver): New defvar.
(system-sleep--sleep-event-handler): Call the new private hook.
(system-sleep--sleep-event-function): Remove. Use
'system-sleep--sleep-event-handler'.
(system-sleep--enable): Use the internal hook.
(system-sleep--enable): [dbus] Probe session bus for screen
saver support.
(system-sleep--disable): Remove the new internal hook.
(system-sleep--block-sleep): Call screen saver dbus endpoint
only when screen saver support is known to exist.
Without this fix, a 64-bit build on Ubuntu 25.10 x86-64 failed
when the libselinux1-dev:i386 package (providing <selinux/selinux.h>)
was installed but the libselinux1-dev package (providing
/usr/lib/x86_64-linux-gnu/libselinux.so) was not.
The first symptom was when compiling emacsclient:
‘/usr/bin/ld: ../lib/libgnu.a(file-has-acl.o): in function
`get_aclinfo': .../lib/file-has-acl.c:247:(.text+0x4d8): undefined
reference to `getfilecon'’.
* configure.ac: Default with_selinux to maybe, not to yes.
Defer our SELinux configuration to after Gnulib’s, so that
we handle any SELinux problems that Gnulib discovers.
project-try-vc--search in a submodule directory tries to find the git
root directory, so the local variable root would be set to nil if it
didn't exist. Calling project--vc-merge-submodules-p on nil would lead
to a crash, so now the while loop aborts beforehand.
* lisp/progmodes/elisp-mode.el
(elisp--highlight-function-argument): Handle special usage
syntax correctly when scanning usage arguments using
'forward-sexp' (bug#8432). Before binding 'origin', skip over
blanks, so as not to highlight them, and to move immediately
before any possible opening square brackets. After binding
'origin' and before calling 'forward-sexp', skip over opening
square brackets, so as to highlight them. After calling
'forward-sexp' and before setting 'start' and 'end', skip over
closing square brackets and periods, so as to highlight them.
* lisp/progmodes/elisp-mode.el
(elisp--highlight-function-argument): Use 'forward-sexp' to move
over usage arguments, handling parenthesized argument patterns
monolithically (bug#8432). Set 'start' and 'end' to the
beginning and end, respectively, of the usage argument.
* lisp/progmodes/elisp-mode.el
(elisp--highlight-function-argument): Insert 'args' into
temporary buffer to prepare for better handling of usage
arguments (bug#8432). Move point after the first opening
parenthesis of the arguments string. In the loop, let `origin'
track the point. No functional change.
* lisp/calendar/diary-icalendar.el (diary-icalendar--tz-is-utc-p): New
function.
(diary-icalendar-convert-time-via-strategy): Don't expect a VTIMEZONE
for UTC times.
(diary-icalendar-export-region): Don't generate a VTIMEZONE for 'local
export strategy in UTC.
* test/lisp/calendar/diary-icalendar-tests.el
(diary-icalendar-test-entry-parser): Don't generate a VTIMEZONE for
'local export strategy in UTC.
* lisp/delsel.el (delete-selection-replacement-face): Delete var.
(delete-selection-replacement): New face, to replace it.
(delsel--replace-overlay, delsel--replace-text): Delete vars and ...
(delete-selection--replacement-text): ...use this single var instead.
(delete-selection--replacement-cursor): New function.
(delete-active-region): Use it with `cursor-sensor-mode` to avoid the
overlay lingering too long.
(delete-selection--replacement-text): New function extracted from
`delete-selection-repeat-replace-region`, with adjustments to account
for the above changes.
(delete-selection-repeat-replace-region): Use it.
* lisp/emacs-lisp/cursor-sensor.el (cursor-sensor--detect): Do use
`get-pos-property` when it works. Fix the `missing-p` subfunction
so as not to get fooled by a missing property at END.
This patch was sent back in 2014 as part of bug#18886.
* lisp/delsel.el (delsel--replace-text-or-position): Delete var.
(delete-selection-replacement-face): New defcustom.
(delsel--replace-text, delsel--replace-overlay): New vars.
(delete-active-region, delete-selection-repeat-replace-region):
Use overlay to track replacement text instead of abusing the
undo-list; this allows the text to be edited before it is
used for substitutions. Add highlight to the replacement text.
Now that json.el uses the new sort calling convention, there's no
need to prefer string< over value<, which may even run faster.
Suggested by Mattias Engdegård <mattias.engdegard@gmail.com>.
* lisp/json.el (json-encoding-object-sort-predicate): Mention value<
in docstring.
(json-pretty-print-buffer-ordered, json-pretty-print-ordered): Use
value< in place of string<.
* test/lisp/json-tests.el (test-json-encode-hash-table-sort): Use
value< as json-encoding-object-sort-predicate in at least one test.
* lisp/emacs-lisp/package.el (package-upgrade): Trigger error
redirecting user to use 'package-vc-upgrade'.
(package--upgradeable-packages): Exclude VC packages from list
of "upgradable" packages.
* lisp/vc/vc.el (vc-pull): Don't fail when called from buffers
visiting unregistered or ignored files so long as there is a
'pull' function available from the backend.
* lisp/vc/vc-hooks.el (vc-find-backend-function): Require vc for
default implementations (bug#80254). Report and fix due to
Daniel Mendler <mail@daniel-mendler.de>.
* lisp/emacs-lisp/vtable.el (vtable--insert-line): Do not
produce a divider after the final column. This thinko is more
noticeable on a tty.
(vtable--insert-header-line): On a tty, nullify indicator
padding.
(vtable-tty-char-pixel-width): New defconst.
(vtable--compute-width): On a tty, adjust column width specified
in pixels down by a factor of 'vtable-tty-char-pixel-width'.
(vtable--alter-column-width): On a tty, adjust column width in
characters, otherwise in pixels.
* lisp/vc/vc-hg.el (vc-hg--bookmarks): New function.
(vc-hg-trunk-or-topic-p):
* lisp/vc/vc-git.el (vc-git--branch-remotes)
(vc-git-trunk-or-topic-p): New optional BRANCH argument.
(vc-trunk-or-topic-p): Declare.
(vc-git-topic-outgoing-base): Consider only local trunks, if
there are any (bug#80006).
* lisp/vc/vc.el (trunk-or-topic-p): New optional BRANCH
argument.
(vc-trunk-or-topic-p): New function.
(vc--outgoing-base): Call it.
* lisp/net/shr.el (shr-dom-print): Escape these strings, as done
in `dom-print', to prevent producing an erroneous XML document.
* test/lisp/net/shr-tests.el (dom-print-escape): Add new test
(Bug#80383).
* doc/lispref/edebug.texi (Edebug, Using Edebug, Instrumenting)
(Source Breakpoints, Specification List): Improve indexing and
tell how to end debugging.
* lisp/textmodes/page-ext.el (pages-directory-revert-function): New
function.
(pages-directory-list-all-headers-p, pages-directory-count-lines-p)
(pages-directory-regexp): New variables to store the page directory
style. (Bug#80319)
* src/xdisp.c (compute_display_string_pos): Pay attention to
'display' properties that come from overlays, in case the overlays
are window-specific. Call 'handle_display_prop' with the argument
OVERLAY non-nil, if the property is from an overlay.
(compute_display_string_end): Accept an additional argument, a
pointer to the window; all callers changed. Pay attention to
'display' properties that come from overlays, in case the overlays
are window-specific. In particular, if the property comes from an
overlay, use that overlay's end position as the next place where
the 'display' property changes, effectively disregarding any
properties on buffer text that is replaced by this overlay's
'display' property.
(handle_single_display_spec): Always use the end position of the
overlay which determined the 'display' property as the end of the
property, to make sure we obey windows-specific overlays.
* src/bidi.c (bidi_fetch_char): Adapt to the above change.
* src/dispextern.h: Adjust prototype of 'compute_display_string_end'.
(Bug#80255)
* lisp/completion-preview.el (completion-preview-commands):
Allow the value t, which says that completion preview should
be attempted after any command.
* lisp/completion-preview.el
(completion-preview-require-certain-commands): Adapt.
* lisp/completion-preview.el
(completion-preview-inhibit-functions): New option.
(completion-preview--post-command): Respect it.
* etc/NEWS: Announce it.
* doc/lispintro/emacs-lisp-intro.texi (Permanent Installation):
Add a cross-reference to "Contributing" in the Emacs user manual.
Suggested by Matto Fransen <matto@matto.nl>. (Bug#80393)
* lisp/speedbar.el (speedbar-get-focus)
(speedbar-frame-or-window): Support for 'speedbar-prefer-window'
with fix of 'speedbar-window' trying to delete current frame.
(Bug#80392)
* src/buffer.c (overlays_in): Fix commentary to match the code.
(Foverlays_in, Foverlays_at): Doc fixes. (Bug#80242)
* test/src/buffer-tests.el (test-overlays-at-2): Add one test.
* doc/lispref/display.texi (Finding Overlays): Update and improve
the documentation of 'overlays-in' and 'overlays-at'.
* etc/NEWS: Announce the changes.
* src/pgtkfns.c (xg_set_icon_from_xpm_data):
* src/xfns.c (xg_set_icon_from_xpm_data):
gdk-pixbuf 2.44 (2025-09) deprecated xg_set_icon_from_xpm_data,
and this breaks --enable-gcc-warnings builds.
For now, pacify GCC by using a pragma.
Uses of <vla.h>’s macro VLA_ELEMS were removed some time ago.
* admin/merge-gnulib (GNULIB_MODULES): Remove vla.

Change the default to 500 (bug#80037).
(vc-print-log-setup-buttons): Have the first button prompt and
propose 4X the current limit as the default.
(vc-print-fileset-branch-log):
Update the reference to the changed button text.
* lisp/vc/log-view.el (log-view-end-of-defun-1): Same.
* doc/emacs/maintaining.texi (VC Change Log): Also here.
