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'.

visiting unregistered or ignored files so long as there is a
'pull' function available from the backend.

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.

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.

function.

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)

Allow the value t, which says that completion preview should
be attempted after any command.

(completion-preview-inhibit-functions): New option.
(completion-preview--post-command): Respect it.

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.

The greedy regexp matching, broken scoring and broken highlight were
sources of frequent complaints about the 'flex' matching style. This
commit fixes that.
Inspired by the 'hotfuzz' style (available at
https://github.com/axelf4/hotfuzz) it uses a modified version of Gotoh's
1982 dynamic programming algorithm. It is strictly more correct than the
"old" flex. For example, when matching the pattern 'goto' to no longer
will 'eglot-format' be sorted before some hypothetical much better
'goobarbaz-goto'. And of course the highlighting is also correctly
placed on the 'goto', not scattered across the candidate.
Regarding performance, it is faster than the naive 'flex', primarily
because of the Elisp rewrite in minibuffer.el. The matching and costing
algorithm matters but is not the bottleneck.
The Elisp parts of the style were almost completely decoupled from the
pcm/substring styles in lisp/minibuffer.el. Only
'completion-flex-try-completion' uses some of pcm's code for pattern
augmentation.
* src/minibuf.c (completion--flex-cost-gotoh): New function.
* lisp/minibuffer.el (completion-flex--pattern-str): New variable.
(flex-score-match-tightness): Make obsolete.

New helper function.

(completion--pcm-score): Delete.
(completion-pcm-test-3, completion-pcm-test-4)
(completion-substring-test-1, completion-substring-test-2)
(completion-flex-test-2, completion-flex-test-3): Tweak.
* etc/NEWS: Describe change.
* lisp/emacs-lisp/package.el (package-dir-info): Do not check
files that do not satisfy 'file-regular-p' when trying to find
the file with the package metadata. (Bug#79742)
