* exec/exec.c (format_pid): Simplify. No need for a local array.
(exec_0): Shrink local buffer.
If names are too long, fail instead of silently truncating them.
Be cautious in case symlink is zero length (shouldn’t be possible
in Android, but it’s easy to be safe).
* src/xterm.c (x_dnd_begin_drag_and_drop): The n_ask_actions arg
is an int, not a size_t, as XChangeProperty supports only int and
our caller passes an int.
* src/json.c (json_out_grow_buf)
(json_make_object_workspace_for_slow_path)
(json_byte_workspace_put_slow_path):
Use xpalloc rather than doing it by hand.
* src/json.c (json_out_grow_buf):
Change arg from needed bytes to minimum increment of bytes.
Caller changed.
* src/alloc.c (STRING_BYTES_MAX): Also don’t allow sizes to exceed
PTRDIFF_MAX in internal calculations when calling malloc, as those
are problematic even if the final number of bytes does not exceed
PTRDIFF_MAX.
* src/alloc.c (memory_full_up): New function. Replace all callers
of memory_full (SIZE_MAX) with callers to this function.
This simplifies callers and should make future changes easier.
It also saves a whopping 296 bytes in executable size
with gcc 16.1.1 20260515 (Red Hat 16.1.1-2) x86-64.

`icalendar-recur' as a type name for RRULE values was confusing and made
the accessors for this type difficult to discover, because `icalendar-recur-'
is also used as a prefix in icalendar-recur.el. This change renames the
`icalendar-recur' type to `icalendar-rrule-value' and renames the
accessor functions for these values appropriately.
* lisp/calendar/icalendar-parser.el: Rename symbols as follows:
(icalendar-recur): `icalendar-rrule-value'
(icalendar-read-recur-rule-part): `icalendar-read-rrule-part'
(icalendar-print-recur-rule-part): `icalendar-print-rrule-part'
(icalendar-recur-rule-part): `icalendar-rrule-part'
(icalendar-read-recur): `icalendar-read-rrule-value'
(icalendar-print-recur): `icalendar-print-rrule-value'
(icalendar--recur-value-types): `icalendar--rrule-value-types'
(icalendar-recur-value-p): `icalendar-rrule-value-p'
(icalendar-recur-freq): `icalendar-rrule-freq'
(icalendar-recur-interval-size): `icalendar-rrule-interval-size'
(icalendar-recur-until): `icalendar-rrule-until'
(icalendar-recur-count): `icalendar-rrule-count'
(icalendar-recur-weekstart): `icalendar-rrule-weekstart'
(icalendar-recur-by*): `icalendar-rrule-by*'.
(icalendar-rrule):
(icalendar-index-insert):
(icalendar-index-get): Update references.
* lisp/calendar/icalendar-recur.el (icalendar-recur-find-interval):
(icalendar-recur-nth-interval):
(icalendar-recur-next-interval):
(icalendar-recur-previous-interval):
(icalendar-recur-refine-from-clauses):
(icalendar-recur-recurrences-in-interval):
(icalendar-recur-recurrences-in-window):
(icalendar-recur-recurrences-to-count):
(icalendar-recur-tz-observance-on): Update references.
* lisp/calendar/diary-icalendar.el: Update references.
* lisp/calendar/icalendar-shortdoc.el (icalendar): Update shortdoc examples.
* lisp/gnus/gnus-icalendar.el: Update references.
* test/lisp/calendar/diary-icalendar-tests.el:
* test/lisp/calendar/icalendar-parser-tests.el:
* test/lisp/calendar/icalendar-recur-tests.el: Update references in tests.
The advantage is that this works also for mixtures of alists and
vectors, as one obtains, e.g., from 'json-parse-buffer' and
'json-parse-string'.
* lisp/emacs-lisp/let-alist.el (let-alist--list-to-sexp): Use
'elt' instead of 'nth'.
(let-alist): Adapt doc string. (Bug#80992)
* lisp/gnus/gnus-msg.el (gnus-inews-make-draft-meta-information):
Escape the group name with prin1-to-string to prevent arbitrary
Lisp injection through crafted group names. The unescaped group
name was embedded into a Lisp-readable string, parsed back with
read-from-string in gnus-draft-setup, and eventually eval'd via
message-do-actions, allowing code execution when a draft was sent.
With Emacs 31 the old_buffer slot of a window gets overwritten
with the buffer unshown in that window when that window is
deleted. Fset_window_configuration triggers that when calling
delete_all_child_windows. If a window configuration gets saved
and restored in one and the same redisplay cycle, the change
time stamps of the window and its frame will be equal and
'window-buffer-change-functions' may wrongly decide that the
window's buffer has not changed because its buffer and
old_buffer slots refer to the same buffer (Bug#81097). Fix that
by saving and restoring the old_buffer slot.
* src/window.c (struct saved_window): Add 'old_buffer' slot.
(Fset_window_configuration): Restore old_buffer slot.
(save_window_save): Save old_buffer slot.
* lisp/isearch.el (lazy-highlight, lazy-highlight-initial-delay)
(lazy-highlight-buffer, isearch-lazy-highlight, isearch-forward):
* lisp/replace.el (query-replace, query-replace-lazy-highlight)
(query-replace, query-replace-regexp): Doc fixes.
* doc/emacs/search.texi (Search Customizations): Document
'lazy-highlight-buffer' and 'lazy-highlight-buffer-max-at-a-time'.
Use @vtable to avoid the need of indexing each variable
separately.
* src/w32proc.c (w32_raise): A more complete, Posix-compliant
implementation.
(sys_signal): Support SIGBREAK.
* src/syssignal.h (raise): Redirect to 'w32_raise'.
* src/atimer.c: Don't redirect 'raise', now done in syssignal.h.
(Bug#80760)
* src/gtkutil.c (xg_frame_set_size_and_position): Remove a
gtk_window_resize call which used a wrong value type
(GdkX11Window instead of GtkWindow). The original motivation
for that line seems to be fixed by later changes (bug#80662).
* lisp/net/shr.el (shr-outline-search):
Don't check for the beginning of the line.
Suggested by Omar Antolín Camarena <omar@im.unam.mx>.
Confirmed by Rahguzar <rahguzar@mailbox.org>.
Quickly verify that the number of unchanged characters before and
after the region that changes are supposed to be limited to doesn't
change.
Suggested by Stefan Monnier.
* lisp/subr.el (combine-change-calls-1): Copy BEG into a marker, and
count the characters after the changed region. After the changes,
ensure the character counts still match.
* test/lisp/subr-tests.el (subr-test-combine-change-calls-error): New.
* lisp/auth-source.el (auth-source-backend-parse): Use `run-hook-wrapped'.
Suggested by Augusto Stoffel <arstoffel@gmail.com>.
Transform a warning into a debug message.
No reason not to. Tested with gfm-view-mode and markdown-ts-mode
* lisp/progmodes/eglot.el (eglot-client-capabilities): Annouce
markdown support for completion docs.
* lisp/textmodes/markdown-ts-mode.el
(markdown-ts--fontify-delimiter): When `markdown-ts-hide-markup'
is enabled in `markdown-ts-view-mode', also hide the whole line
containing a `fenced_code_block_delimiter' (including its
terminating newline) so Eldoc/LSP markdown snippets render
without stray blank lines around the code block. Scoped to
view-mode and to fenced delimiters on purpose: the same handler
is shared by inline delimiters (emphasis, code span, link
brackets) where munching surrounding whitespace would collapse
word separators, and tuning rendering for
hide-markup-while-editing is not a goal.
The grammar reports leading spaces as part of the atx_heading "marker"
and we cannot use the length of the marker as a result. Instead, count
the number of consecutive # after any blanks to determine its "level."
* lisp/textmodes/markdown-ts-mode.el
(markdown-ts--fontify-atx-heading): Count the octothorpes rather
than using the length of the marker node's text.
Do not assume every command run in
'markdown-ts--run-command-in-code-block' produces output that needs to
be merged from the temp/work buffer into the source buffer. One example
is 'xref-find-definitions', the temp buffer of which is unrelated to the
source buffer.
* lisp/textmodes/markdown-ts-mode.el
(markdown-ts-code-block-commands): Add 'complete-symbol'.
(markdown-ts-code-block-ignore-output-commands): New defvar.
(markdown-ts--run-command-in-code-block): Ignore command output
when necessary.
This avoids an alloca in x_set_mouse_color.
* src/xfns.c (x_set_mouse_color): Use local array rather than
alloca, since the string is small.
* src/xterm.c (X_ERROR_MESSAGE_SIZE): Move defn from here ...
* src/xterm.h: ... to here, and make it an enum not a macro.
* src/sysdep.c (serial_open): On failure, simply return -1
and set errno; do not call report_file_error, as the
caller is supposed to do that if needed.
