* src/lread.c (read_vector): If the vector is to short to be for
bytecodes don’t do bytecode processing for it, as the processing
might run past the end of the vector.
* configure.ac: Clarify wording for --with-wide-int help.
* src/pdumper.c (dump_vectorlike_generic):
Do the eassert even if --with-wide-int was specified unnecessarily.
Reported by Ture Pålsson.
* lisp/international/ucs-normalize.el
(ucs-normalize-hfs-nfd-post-read-conversion)
(ucs-normalize-hfs-nfd-pre-write-conversion):
Use save-match-data to avoid match data clobber in normalisation.
* test/lisp/international/ucs-normalize-tests.el
(ucs-normalize-save-match-data): New test.
Performance issue reported by Eli Zaretskii (Bug#41321#149).
* src/alloc.c (GC_OBJECT_ALIGNMENT_MINIMUM): New constant.
(maybe_lisp_pointer): Use it instead of GCALIGNMENT.
* src/lisp.h (struct Lisp_Float): Declare via
GCALIGNED_UNION_MEMBER, not via GCALIGNED_STRUCT, since alloc.c
creates these in arrays and GCALIGNED_STRUCT does not necessarily
suffice to align struct Lisp_Float when it’s used in an array.
This avoids undefined behavior on oddball machines where
sizeof (struct Lisp_Float) is not a multiple of 8 and the compiler
does not support __attribute__ ((aligned 8)).
* src/alloc.c (union emacs_align_type): Move to here ...
* src/lisp.h: ... from here, and uncomment out some of the
types that alloc.c can see but lisp.h cannot.
* src/alloc.c (MALLOC_ALIGNMENT_BOUND): Remove.
(LISP_ALIGNMENT): Go back to yesterday’s version, except use
union emacs_align_type instead of max_align_t.
(MALLOC_IS_LISP_ALIGNED): Go back to yesterday’s version.
(maybe_lisp_pointer): Check against GCALIGNMENT, not LISP_ALIGNMENT.
* src/lisp.h (union emacs_align_type): Bring back.
This is simpler, and fixes a bug in the previous fix.
* src/alloc.c (MALLOC_ALIGNMENT_BOUND): Simplify by
using max_align_t, since the buggy implementations won’t
break this simpler implementation.
(LISP_ALIGNMENT): Simplify by just using GCALIGNMENT, since the
fancier implementation wasn’t correct anyway, and fixing it
isn’t worth the trouble on practical platforms.
* src/lisp.h (union emacs_align_type): Remove.
Problem reported by Eli Zaretskii (Bug#41321).
* src/alloc.c (MALLOC_ALIGNMENT_BOUND): New constant.
(LISP_ALIGNMENT): Lower it to avoid crashes on MinGW and similarly
buggy platforms where malloc returns pointers not aligned to
alignof (max_align_t). But keep it higher on platforms where this
is known to work, as it helps GC performance.
(MALLOC_IS_LISP_ALIGNED): Define in terms of the other two.
* src/alloc.c (stacktop_sentry):
* src/thread.c (run_thread):
Don’t overalign or oversize stack sentries; they need to be
aligned only for pointers and Lisp_Object, not for arbitrary
pseudovector contents.
* src/lisp.h (union emacs_align_type): New type, used for
LISP_ALIGNMENT.
The metamail package was last released in 1994, and has been removed
from most GNU/Linux distributions due to being buggy and unmaintained.
* lisp/mail/metamail.el: Move from here...
* lisp/obsolete/metamail.el: ...to here.
* etc/NEWS: Mention its obsoletion.
At least for me, 'auto-save-visited-mode' is very slow and blocks user
interaction for files visited over TRAMP. Therefore, I'd like a
mechanism to disable it for some buffers (namely, those visiting
remote files).
* (auto-save-visited-mode): Document that 'auto-save-visited-mode' can
be set to nil buffer-locally.
* etc/NEWS: Document new behavior.
Otherwise, we end up permanently modifying eshell-mode-map when
running eshell-command.
* lisp/eshell/eshell.el (eshell-command-mode): New mode, with map to
contain the bindings previously set by eshell-return-exits-minibuffer.
(eshell-return-exits-minibuffer): Make into obsolete alias for
eshell-command-mode.
(eshell-command): Use eshell-command-mode instead of
eshell-return-exits-minibuffer.
* lisp/progmodes/cc-langs.el (c-operators): Add co_await and co_yield to the
C++ value of "Exception" keywords.
(c-return-kwds): Create a C++ value containing co_return.
(c-simple-stmt-kwds): Add co_return to the C++ value.
Copyright-paperwork-exempt: yes.

This was missed in a previous commit to remove obsolete libraries.
Its deletion was already announced in NEWS.
* lisp/obsolete/levents.el: Delete file. This library has been
obsolete since 23.2.
Practice shows that the vast majority of projects only use one main
root. The users of this API very often make this assumption as well.
The rest of the "roots" should be possible to express through
project-external-roots.
* lisp/progmodes/project.el: Update the commentary.
Only 4 non-obsolete generics now.
(project-root): Replacement for `project-roots'.
All callers updated. Implementations too.
(project-roots): Declare obsolete.
(project-external-roots): Simplify the docstring.
(project-ignores): Update the docstring.
(project-find-regexp): Omit the second arg to project-files.
(project--dir-ignores): Simplify.
(project-compile): Simplify, remove outdated comment.
* lisp/cedet/ede.el: Add a FIXME.
* lisp/net/eww.el (eww): Use function-put in place of put, as
recommended in "(elisp) Symbol Plists".
(eww-follow-link):
* lisp/net/shr.el (shr-browse-url): Rather than call browse-url-mail
directly, call browse-url which respects the user options
browse-url-handlers and browse-url-mailto-function. (Bug#41133)
(shr--current-link-region): Return nil if there is no link at point.
(shr--blink-link): Adapt accordingly.
(shr-fill-line, shr-indent, shr-table-body): Refactor to avoid some
unnecessary allocations.
* etc/NEWS: Announce that eww-follow-link and shr-browse-url support
custom URL handlers.
* etc/NEWS: Announce that json-read-number is now stricter.
* json.el: Bump package version.
(json-encoding-lisp-style-closings, json-pre-element-read-function)
(json-post-element-read-function, json-advance, json-peek)
(json--path): Clarify and improve style of doc strings.
(json-join): Define as an obsolete alias of string-join.
(json-alist-p, json-plist-p): Refactor for speed and declare as
pure, side-effect-free, and error-free.
(json--plist-reverse): Rename function...
(json--plist-nreverse): ...to this, making it destructive for speed.
All callers changed.
(json--plist-to-alist): Remove, replacing single use with map-pairs.
(json--with-indentation): Accept multiple forms as arguments, fix
their indentation, and allow them to be instrumented for debugging.
Add docstring.
(json-pop, json-read-keyword, json-add-to-object)
(json-encode-array): Simplify for speed.
(json-skip-whitespace): Put newline before carriage return for
likely frequency of occurrence, and so that the characters appear in
increasing order.
(json--check-position): Use 1+.
(json-path-to-position): Open code apply-partially.
(json-keywords): Turn into a defconst and mark as obsolete now that
it is no longer used.
(json--post-value, json--number, json--escape): New rx definitions.
(json-encode-keyword): Declare as side-effect-free.
(json-read-number): Reject leading zeros and plus signs, and make
integer part mandatory in accordance with JSON standards and for
consistency with native JSON parsing functions. Eagerly signal
json-number-format when garbage follows a valid number, e.g., when
reading "1.1.1", instead of leaving that up to the caller. Remove
optional internal argument from advertised calling convention now
that the function is no longer recursive.
(json-encode-number): Define as an alias of number-to-string.
(json-special-chars): Turn into a defconst.
(json-read-escaped-char, json-new-object, json-read-file)
(json-pretty-print): Simplify.
(json-read-string): For consistency with other json.el error
reporting, remove check for leading '"', and use the integer value
rather than the printed representation of characters in error data.
At EOB signal json-end-of-file instead of json-string-format.
(json--long-string-threshold, json--string-buffer): New variables.
(json-encode-string): Reimplement in terms of buffer manipulation
for speed (bug#20154).
(json-read-object): Escape ?\} properly.
(json--encode-alist): New function extracted from json-encode-alist.
(json-encode-hash-table, json-encode-alist, json-encode-plist): Use
it to avoid destructively modifying the argument when
json-encoding-object-sort-predicate is non-nil without incurring
unnecessary copying (bug#40693). Encode empty object as "{}" even
when pretty-printing. Simplify for speed.
(json-read-array): Avoid recomputing list length on each iteration
when json-pre-element-read-function is non-nil. Make first element
of json-array-format error data a string for consistency with
json-object-format and to make the displayed error message clearer.
(json-readtable-dispatch): Accept any kind of argument, not just
symbols. Generate the table in a simpler manner so the dispatch
order is clearer. Remove dispatch on ?+ and ?. now that
json-read-number is stricter and for consistency with native JSON
parsing functions. Signal json-end-of-file if argument is nil.
(json-read): Simplify accordingly.
(json-encode): Avoid allocating a list on each invocation.
* lisp/jsonrpc.el (jsonrpc--json-read, jsonrpc--json-encode): Check
whether native JSON functions are fboundp only once, at load time.
* lisp/progmodes/python.el (python--parse-json-array): New function.
(python-shell-prompt-detect): Use it to parse JSON directly as a
list rather than converting from a vector.
* test/lisp/json-tests.el (json-tests--with-temp-buffer): Allow
instrumenting for debugging.
(test-json-join, test-json-plist-to-alist): Remove tests.
(test-json-alist-p, test-json-plist-p, test-json-advance)
(test-json-peek, test-json-pop, test-json-skip-whitespace)

(test-json-read-from-string, test-json-encode): Extend tests.
(test-json-plist-reverse): Rename test...
(test-json-plist-nreverse): ...to this and avoid modifying literal
lists.
(test-json-read-number): Rename test...
(test-json-read-integer): ...to this, focusing on integers.
(test-json-add-to-object): Rename test...
(test-json-add-to-alist): ...to this, focusing on alists.
(json-encode-simple-alist): Rename test...
(test-json-encode-alist): ...to this, extending it.
(test-json-encode-alist-with-sort-predicate): Rename test...
(test-json-encode-alist-sort): ...to this, extending it.

(test-json-read-invalid): New tests.
(test-json-path-to-position-no-match): Use should-not.
(test-json-read-object): Move error check to new test
test-json-read-object-invalid.
(test-json-pretty-print-object): Adapt test now that empty objects
are pretty-printed as "{}".
* lisp/version.el: Don’t put an RCS Id style string into the
executable via purecopy, as this does not work with the pdumper.
* src/emacs.c (RCS_Id): New constant, for 'ident'.
