* lisp/calendar/time-date.el (format-seconds): Document that the arg
can be any time value, and need not be a number.
This has been true for some time, but has not been documented.
Avoid some (but not all) rounding errors internally, and add a
comment about the remaining rounding error.
* lisp/emacs-lisp/timer-list.el (list-timers):
* lisp/org/org-timer.el (org-timer-show-remaining-time):
* lisp/org/ox.el (org-export--stack-generate):
* lisp/time.el (emacs-uptime): Omit unnecessary conversion of time
value that can increase rounding error.
* test/lisp/calendar/time-date-tests.el (test-format-seconds):
Test that format-seconds works on time values that are not numbers.
The two -respondsToSelector: guards in -[EmacsWindow
setParentChildRelationships] tested @selector(toggleFullScreen) without
the trailing colon, but the method is -toggleFullScreen:. The colon-less
selector matches nothing, so the guarded code was always skipped. This
is inert on modern builds (MAC_OS_X_VERSION_MIN_REQUIRED >= 1070, where
the check is #if'd out), but on a binary targeting pre-10.7 yet running
on 10.7+ it would wrongly skip taking a child frame out of native
fullscreen.
* src/nsterm.m ([EmacsWindow setParentChildRelationships]): Add the
missing colon to both @selector(toggleFullScreen:) checks.
The new FOR_EACH_TAIL code detects simple cycles sooner than the old
code did, leading to integer overflows.
* src/fns.c (Fnthcdr): Avoid integer overflow if cycle is detected
early.
* src/lisp.h (struct for_each_tail_internal): Reduce to two words.
(FOR_EACH_TAIL_BASIC): Add compiler hint to indicate that tail is most
likely Qnil after the loop and a non-nil non-cons is unlikely.
(FOR_EACH_TAIL_STEP_CYCLEP): Rewrite.
* src/process.c (glib_installs_sigchld_handler): New variable.
(init_process_emacs): Set it when GLib overrides Emacs's SIGCHLD
handler.
* src/process.h (glib_installs_sigchld_handler): Declare.
* src/xwidget.c (Fmake_xwidget): Skip the "about:blank"
workaround when glib_installs_sigchld_handler is false.
* lisp/vc/vc-bzr.el (vc-bzr-dir-status-files):
* lisp/vc/vc-cvs.el (vc-cvs-dir-status-files):
* lisp/vc/vc-git.el (vc-git-dir-status-goto-stage):
* lisp/vc/vc-hg.el (vc-hg-dir-status-files):
* lisp/vc/vc-svn.el (vc-svn-dir-status-files): Set the
query-on-exit flag for the processes populating VC-Dir buffers
to nil.
* lisp/plstore.el (plstore-find, plstore-get, plstore--encode)
(plstore--decode): Use 'plstore--has-secret-keys' to replace
manual check for existence of secret keys. (Bug#81061)
This fixes bug#81084.
* lisp/progmodes/cc-engine.el (c-forward-decl-or-cast-1):
In the test for a cast near the end of the function, add a test
for a {...} block which isn't a statement block, allowing such
blocks to be recognized as operands of casts.
* lisp/textmodes/markdown-ts-mode.el
(markdown-ts--fontify-unordered-list-marker): Skip leading
whitespace in the node range before applying the display bullet,
since the tree-sitter grammar bundles indent into the first
list_marker_* node.
When a plstore has entries with secret keys, processing the plstore
file would require decryption first. However, unlike other functions
like 'plstore-get', 'plstore-put', etc., 'plstore-delete' does not
check for secret keys and decrypt the file, which would corrupt the
file when deleting any entries with secret keys.
This patch adds checking for secret keys and decrypt the file when
needed before removing the entry with name.
* lisp/plstore.el (plstore--has-secret-keys): New.
* lisp/plstore.el (plstore-delete): Check for secret keys of the entry
and decrypt plstore before performing the deletion. (Bug#81061)
* src/xterm.c (x_suspend_background_fills)
(x_restore_background_fills): New functions.
(x_set_window_size, x_set_window_size_and_position)
(x_make_frame_invisible): Use them (bug#80961).
* src/gtkutil.c (xg_frame_set_char_size)
(xg_frame_set_size_and_position): Round WIDTH and HEIGHT to
multiples of SCALE without adding toolbar/menubar (bug#80662).
* lisp/vc/vc.el (vc--subject-to-file-name): Make the prefix
regex less greedy, ensure the result has no text properties,
improve the docstring (bug#81017).
* lisp/erc/erc-goodies.el (keep-place-indicator): Add
`erc-keep-place-indicator-arrow' face to overlay arrow.
* lisp/erc/erc-stamp.el (erc-stamp--display-prompt-in-left-margin)
(erc--conceal-prompt): Add `erc-prompt-face' to entire `left-margin'
string. See also 9ba65aa9 "Fix missing margin face on display prop in
erc-stamp".
* test/lisp/erc/erc-fill-tests.el (erc-fill--left-hand-stamps): Update
expected text properties on prompt. (Bug#80693)
Now that markdown-ts-view-mode is demoted to "experimental" in emacs-31,
simplify bits of eglot.el and rewrite docs to be more neutral. In
practice 'gfm-view-mode' is still used if found, just like before, but
intrepid users can still try the "experimental" modes.
* lisp/progmodes/eglot.el (eglot-documentation-renderer): Rewrite
doc string.
(eglot--accepted-formats): Rewrite.
(eglot--builtin-mdown-p): Remove.
* doc/misc/eglot.texi (Customization Variables): Rewrite entry.
* etc/EGLOT-NEWS: Tweak.
Ported from emacs-31 release branch:
commit 984932d4dc
Author: Sean Whitton <spwhitton@spwhitton.name>
Date: Mon Jun 1 11:48:42 2026 +0100
Disable markdown-ts-mode & markdown-ts-view-mode for Emacs 31
This synchronizes master's Eglot with emacs-31. The goal of that commit
is to demote those markdown-ts-mode.el modes to "experimental" status in
emacs-31, but Eglot was already relying on them and changes were needed.
984932d4dc is not the commit that best
does those changes, but since that commit was marked "do not merge" on
emacs-31, I thought it best to bring it here manually so any further
work -- which doesn't contradict the overarching intention -- can
continue in emacs-31 with clean merges to master (where the GNU-devel
core Elpa package is pulled from).
* lisp/progmodes/eglot.el (eglot-documentation-renderer)
(eglot--format-markup): Don't call eglot--builtin-mdown-p.
* doc/misc/eglot.texi (Customization Variables):
* etc/EGLOT-NEWS: Don't mention markdown-ts-mode
Co-authored-by: Sean Whitton <spwhitton@spwhitton.name>
Problem reported by Helmut Eller (Bug#81132#25).
* src/dispextern.h (IF_DEBUG): Omit cast that is useless if
the argument is already void.
* src/ftfont.c (adjust_anchor): Omit useless cast.
