* configure.ac (ALIGNOF_INT, ALIGNOF_LONG, ALIGNOF_LONG_LONG):
New variables.
(emacs_cv_alignas_unavailable): Define if alignas and structure
alignment primitives are unavailable. In such an environment,
the MSB tagging scheme must be enabled, as must the GNU malloc.
* msdos/sed2v2.inp: Adjust correspondingly.
* src/alloc.c (union emacs_align_type): Remove types which
contain flexible array members. The address of a field
subsequent to an aggregate with flexible array members cannot
validly be taken.
(mark_memory) [!USE_LSB_TAG && !WIDE_EMACS_INT]: Strip type bits
before scanning memory.
* src/emacs.c (main):
* src/eval.c (Fautoload_do_load):
* src/fns.c (Frequire): Rename a number of illogically named
fields.
* src/lisp.h (ALIGNOF_EMACS_INT): Define to the natural
alignment of EMACS_INT.
(IDEAL_GCALIGNMENT): New macro.
(USE_LSB_TAG): Disable if no alignment specifiers are available,
WIDE_EMACS_INT is undefined, and the natural alignment of
EMACS_INT falls short of LSB tagging's requirements.
(gflags): Rename illogically named fields and don't define them
as bitfields, which runs afoul of certain compiler issues.
(will_dump_p, will_bootstrap_p, will_dump_with_pdumper_p)
(dumped_with_pdumper_p): Adjust accordingly.
* src/pdumper.c (VM_SUPPORTED): Define to 0 when !USE_LSB_TAG.
It is better to read dump files into the heap by hand than to be
supplied with an address that is not representable.
(_dump_object_start_pseudovector): Rename to
dump_object_start_pseudovector, to avoid encroaching on reserved
names.
(START_DUMP_PVEC): Adjust correspondingly.
(dump_mmap_contiguous_vm): Preserve errno around failure
cleanup.
(dump_bitset_bit_set_p): Work around certain compiler issues.
(pdumper_load) [!USE_LSB_TAG]: Reject dump file allocations
that are not representable as Lisp_Objects.
Tested on i386-unknown-solaris2.10, sparc-sun-solaris2.10.
* lisp/emacs-lisp/find-func.el
(find-function-mode-lower-precedence): New option.
(find-function-mode-map): Restore.
(find-function-mode): Don't unconditionally bind keys into the
global map. Instead respond to the new user option (bug#76700).
* etc/NEWS: Mention the new option in existing entry.
* lisp/custom.el (custom--should-apply-setting): Return non-nil
for an enabled theme. Provide docstring. This allows for users
to reevaluate a custom-theme-set-* function and see the settings
applied right away. (Bug#76685)
(custom--inhibit-theme-enable): Adapt docstring.
* etc/NEWS: Announce the new behavior.
* src/term.c (tty_write_glyphs_1): Renamed from tty_write_glyphs. Don't
check if writing the bottom-right corner.
(tty_write_glyphs): New function handling case of writing to the
bottom-right corner, and otherwise calling tty_write_glyphs_1.
* lisp/vc/ediff-mult.el (ediff-collect-custom-diffs): If the
diff buffer is visiting a file, create a new buffer. (Bug#3348)
* test/lisp/vc/ediff-mult-tests.el: New test file.
* lisp/comint.el (comint-watch-for-password-prompt): Add a trailing
space character to the minibuffer password prompt, if it does not
contain one already, per the minibuffer UI conventions.
Bug#76604
* lisp/display-fill-column-indicator.el
(display-fill-column-indicator-warning): New user option.
(display-fill-column-indicator-warning-face): New face.
(display-fill-column-indicator-mode): Add post-command-hook
if `display-fill-column-indicator-warning' is ON. (Bug#76494)
Add a hook function to strip all lines beginning with "CVS:" from the
commit message as CVS does. Do this only if 'log-edit-vc-backend' is
'CVS'. (Bug#72341)
* lisp/vc/log-edit.el
(log-edit-done-strip-cvs-lines): New command.
(log-edit-done-hook): Add it as an option.
* test/lisp/vc/log-edit-tests.el
(log-edit-done-strip-cvs-lines-helper): New function.
(log-edit-done-strip-cvs-lines-cvs)
(log-edit-done-strip-cvs-lines-non-cvs)
(log-edit-done-strip-cvs-lines-only-cvs-colon-blank)
(log-edit-done-strip-cvs-lines-only-cvs-colon): New test cases.
* etc/NEWS: Mention log-edit-done-strip-cvs-lines.
* lisp/progmodes/etags-regen.el (etags-regen--append-tags): Move
the "-o" option to before the filename, as Ctags doesn't allow
it to follow the file name. (Bug#76855)
Copyright-paperwork-exempt: yes
In order to fix one of the issues discussed in bug#61413, i.e.
'buttonize' clobbering the help-echo property set by
'icon-string'.
This is a reasonable interpretation of the button.el
docstrings - "if HELP-ECHO, use that as the `help-echo'
property"; conversely, if not HELP-ECHO, then do not do
anything, preserving existing values for that property.
* lisp/button.el (button--properties): Only add a help-echo
property if HELP-ECHO is non-nil. Add an additional property
for bookkeeping.
(unbuttonize-region): Check for that bookkeeping property
before clearing help-echo.
* test/lisp/button-tests.el (button--preserve-help-echo):
Validate these changes.
Munge this-command when we hit a movement barrier so we override only on
the very next command instead of at the end of a sequence of movement
commands that didn't encounter a barrier.
* (windmove-do-window-select): Use last-command to remember that we hit
a barrier.
* src/pdumper.c (dump_sort_copied_objects, drain_reloc_list)
(dump_do_fixups, dump_do_dump_relocation): Do not expand
Fnreverse multiple times in CALLN. Sun C 5.12 evaluates the
arguments to array initializers to which it expands, which
clobbers the lists being reversed.
* src/frame.c (delete_frame): Ignore tooltip frames when looking
for other frames on the same terminal. (Bug#76842)
(cherry picked from commit d2445c8c23)
This reverts commit 331492a148.
My bad: gensym wasn't the problem, it's available from 26.1. Incf
was the problem, in the main program file.
* test/lisp/progmodes/eglot-tests.el (eglot--with-timeout): Back to gensym
;; IMPORTANT: Since Eglot is a :core ELPA package, these tests are
;; supposed to run on Emacsen down to 26.3. Do not use bleeding-edge
;; functionality not compatible with that Emacs version.
* test/lisp/progmodes/eglot-tests.el (eglot--call-with-timeout):
Back to cl-gensym.
* admin/notes/jargon: Add some more acronyms, remove some rare ones,
add section headers "Acronyms" and "Glossary", add entries under
"Glossary", sort, fix formatting, realign.
For some reason, MELPA emits the keyword :maintainers, despite it
being unsupported and thus leads to the "Maintainer" field being empty
in all released Emacs versions. That said, it seems like a good idea
to support the plural form, to be consistent with :authors.
* lisp/emacs-lisp/package.el (describe-package-1): Support
:maintainers in plural, in addition to :maintainer, to be consistent
with :authors.
We shouldn't move a line marker just because we cleared a line next to
it. clear-in-line is defined not to affect line structure.
* lisp/term.el (term-erase-in-line): use insert-before-markers
When handling \e[<N>K escape sequences, we're supposed to erase both to
the left _and_ to the right of the cursor when N is two.
* lisp/term.el (term-erase-in-line): make condition check more correct
* lisp/emacs-lisp/ert-font-lock.el: Remove redundant requires.
(ert-font-lock--parse-macro-args): First return value 'doc' being
nil already indicates omission of a docstring, so remove redundant
second return value doc-p. All users updated. Fix error
messages (bug#76372).
(ert-font-lock--check-faces): Simplify with ensure-list.
