Problem reported by Lars Ingebrigtsen, and problem diagnosis
and most of this patch by Pip Cet (Bug#42832).
* src/pdumper.c (dump_bitsets_init): Rename from dump_bitset_init.
All callers changed. Initialize two bitsets with a single malloc
call.
(struct pdumper_loaded_dump_private): New member last_mark_bits.
(pdumper_find_object_type_impl): Return PDUMPER_NO_OBJECT if
the last_mark_bits’ bit is clear.
(pdumper_set_marked_impl): Assert that the last_mark_bits’
bit is set.
(pdumper_clear_marks_impl): Save mark_bits into
last_mark_bits before clearing mark_bits.

* configure.ac (OPTION_DEFAULT_IFAVAILABLE): New macro. Use it to
define the --with-json option. Add with_json and HAVE_JSON to the
'MISSING' checks (bug#39953).
* etc/NEWS: Note that Emacs needs to be built with systemd support
systemd is used to stop/start Emacs (bug#42242). Change suggested by
Bhavin Gandhi <bhavin7392@gmail.com>
* lisp/vc/diff-mode.el (diff--font-lock-prettify): Fix problems
with visual gaps in the fringes when changing font size (bug#42300).
Copyright-paperwork-exempt: yes
* lisp/progmodes/subword.el (c-subword-mode): Clarify that this
obsolete function alias should not be removed just yet. There is a
copy of this definition in cc-cmds.el, obsolete since 24.3, and it is
better to delete both at the same time.
* test/lisp/progmodes/cperl-mode-tests.el: Adjust for `perl-mode`.
(cperl-test-ppss): Rename from `cperl-test-face` and change return value.
(cperl-mode-test-bug-42168): Test the `syntax-ppss` state rather than
the font-lock faces, so it works for both `perl-mode` and `cperl-mode`.
* lisp/cus-edit.el (Custom-save): Only act on edited widgets in the
buffer. If we attempt to redraw all widgets, we confuse
custom-variable-modified-p, or we end up drawing State buttons for
all options, including the hidden ones (bug#42801).
* lisp/progmodes/compile.el (compilation-next-single-property-change):
Parse whole buffer at once (bug#42806).
Also remove the comment that mentioned that it is an option to do it
in one go as we now actually start doing. As the existence of that
comment suggested, there is not really a reason to process the buffer
in small chunks. On the contrary, processing the output in arbitrary
units can result in certain constructs not being recognized because
they begin in one arbitrary chunk, while ending in another.
* lisp/progmodes/project.el: Depend on xref. Bump the version.
* lisp/progmodes/xref.el: Remove 'project' from the list of
dependencies. Depending on Emacs 26.3 already ensures that some
version is available. Bump the version.
(xref--process-file-region): Move from project.el with a rename.
Update the sole caller.
(xref-backend-references): Make compatible with old project.el.
Update the docstring.
* lisp/mail/flow-fill.el (fill-flowed): Loop until all flowed lines
are collected.
* test/lisp/mail/flow-fill-tests.el
(fill-flow-tests-fill-flowed-decode): Also test for multiple
flowed lines (bug#42855).
* lisp/icomplete.el (icomplete-show-matches-on-no-input): Doc fix.
(icomplete-completions): Set completion-content-when-empty.
* lisp/minibuffer.el (completion-content-when-empty): New variable.
(completion--complete-and-exit): Use it (bug#19032).
Based on a patch by Matthew Leach <matthew@mattleach.net>.
* lisp/cedet/semantic/bovine/c.el (semantic-c-end-of-macro):
Make into obsolete function alias for 'c-end-of-macro'.
(semantic-lex-cpp-define, semantic-lex-c-macrobits):
* lisp/cedet/semantic/lex-spp.el (semantic-lex-spp-paren-or-list):
Adjust callers.
This reverts commit 1bed252ae9.
Juri Linkov says:
This patch breaks Info fontification, please revert it.
Here is what I said in the message sent later with another patch at
https://debbugs.gnu.org/14645#14
Using the text property `face' instead of `font-lock-face'
might break something, so a better patch below removes
the text properties `face info-index-match' from the Info buffer
* lisp/simple.el (count-words): Ensure that `forward-word-strictly'
moves point from one field to the next during the word-counting loop.
Copyright-paperwork-exempt: yes
* lisp/progmodes/cperl-mode.el (cperl-find-pods-heres):
Recognize {$a++ / $b} correctly as division. (Bug#42168)
* test/lisp/progmodes/cperl-mode-tests.el: New file with test
verifying the fix.
The following commits were skipped:
c9a739408d Fix face merging at EOL when inherited face specifies :extend
f946e48bf5 Fix face extension past EOL in overlay strings
* src/xfaces.c (merge_face_ref): Handle correctly faces that
inherit from another, and in addition specify :extend.
(Bug#42552)
(cherry picked from commit 39c90f8dfa)
* src/xdisp.c (face_at_pos): Pass ATTR_FILTER to
face_for_overlay_string.
* src/xfaces.c (face_for_overlay_string): Accept an additional
argument ATTR_INDEX and pass it to merge_face_ref for merging the
face at POS. This ensures a face from buffer text will not be
merged unless it specifies the :extend attribute. (Bug#42552)
* src/dispextern.h (face_for_overlay_string): Adjust prototype.
(cherry picked from commit 35564bea4d)
* lisp/info.el (Info-fontify-node): Preserve the face foreground.
Previously `Info-index' added the `info-index-match' face to the
strings of the found index entries. Later
`Info-virtual-index-find-node' inserts strings to the Info buffer.
And finally `Info-fontify-node' puts the `font-lock-face' property
with `info-xref' on links. The `face info-index-match' takes
precedence over `font-lock-face info-xref' (bug#14645).
