You can trigger this rather obscure bug by enabling selective display
if the second glyph in its display vector has an invalid face. For
example, evaluate
(set-display-table-slot standard-display-table
'selective-display [?A (?B . invalid)])
and then enable selective display.
* src/xdisp.c (next_element_from_display_vector): Check whether next
glyph code is valid before accessing it.
This is a regression from Emacs 26.
Reported by Phillip Stephani.
* lisp/emacs-lisp/rx.el (rx--pcase-transform): Process ? and ?? correctly.
* test/lisp/emacs-lisp/rx-tests.el (rx-pcase): Add test case.
(cherry picked from commit 575b0681d9)
* src/xdisp.c (CHAR_COMPOSED_P): If the bidi_p flag is not set,
pass -1 to composition_reseat_it, so that the shaping engine will
figure out the directionality of the text. This is important,
e.g., when using move_it_* functions in some context that is not
redisplay, such as 'window-text-pixel-size'. (Bug#44521)
* lisp/mail/uudecode.el (uudecode-decode-region-internal): Fix
inserting the decoded string into a multibyte buffer. Optimize by
working with characters, not strings. (Bug#44411)

* lisp/window.el (split-window): Make new window inherit any
'min-margins' parameter from WINDOW so that horizontal splits
reliably produce windows of same width (Bug#44483).
Do not merge to master.
* lisp/finder.el (finder-exit): Fix exiting the finder-commentary
buffer. (Bug#44384)
(finder-buffer): New defconst.
(finder-list-keywords): Use above new defconst.
* src/bidi.c (bidi_at_paragraph_end, bidi_find_paragraph_start):
Bind inhibit-quit to a non-nil value around calls to
fast_looking_at, to prevent breaking out of redisplay_window,
which temporarily moves point in buffers shown in non-selected
windows. (Bug#44448)
* doc/misc/widget.texi (Basic Types): Document what an external value
is. Document that a :match function expects the value to be in the
external format. (Bug#8717)
* etc/schema/schemas.xml: Recover the file, which was apparently
(mostly) removed by mistake by commit 165f738382 (bug#42851).
Copyright-paperwork-exempt: yes
* doc/lispref/commands.texi (Key Sequence Input): Add documentation for
missing special window areas. Explicitly call out window or frame.
(cherry picked from commit a105db13e1)
* lisp/emacs-lisp/package.el (package-generate-description-file):
Don't include the full name of the source file in the header,
since that varies non-reproducibly according to the build directory.
https://bugs.debian.org/972861
Note that elpa.gnu.org's admin/archive-contents.el does this by hand
and already only includes the nondirectory part.
* src/emacs.c (DAEMON_MUST_EXEC): Define unconditionally on
Cygwin, not just if HAVE_NTGUI is defined. This fixes the failure
of 'emacs --daemon' to start on the non-w32 Cygwin builds.
(Bug#44285)
* lisp/progmodes/cc-engine.el (c-forward-over-decl-or-cast-1): (after CASE 2)
test variables got-suffix-after-parens and at-decl-end before invoking
c-fdoc-shift-type-backward.
* lisp/window.el (fit-mini-frame-to-buffer,
window--resize-mini-frame, fit-frame-to-buffer,
fit-frame-to-buffer-1): By default, fit a mini frame without skipping its
buffer's leading or trailing empty lines.
* src/frame.c (resize-mini-frames): Update doc-string.
* lisp/cus-start.el (resize-mini-frames): Update for customize.
* doc/lispref/minibuf.texi (resize-mini-frames): Update description.
* lisp/display-fill-column-indicator.el
(display-fill-column-indicator-mode): Mention the globalized
version in the doc string.
* doc/emacs/display.texi (Displaying Boundaries): Improve and
clarify the documentation of display-fill-column-indicator.
Suggest using the minor mode as the primary means for turning the
feature on.
* src/xdisp.c (syms_of_xdisp) <display-fill-column-indicator>
<display-fill-column-indicator-character>: Doc fix. (Bug#44226)
* src/xwidget.c (Fmake_xwidget): Enable sandboxing if WebKit 2.26
or later. Do this early, as required for sandboxing (Bug#43071).

* src/xdisp.c (maybe_produce_line_number): Prevent freeing of
realized faces for as long as we are using lnum_face_id and
current_lnum_face_id for producing glyphs. (Bug#44111)
This will prevent version mismatches between compile time and runtime
versions. This fixes bug #43037.
* lisp/Makefile.in: Make js.el dependent on cc-{defs,engine,mode}.elc.
* src/keyboard.c (make_lispy_position): Don't exclude the
window_or_frame = frame case from TTY-only builds. Reported by
Jared Finder <jared@finder.org>.
* doc/lispref/commands.texi (Click Events): Document the format of
POSITION in click events on the frame's internal border.
