The interplay between nontrivial completion boundaries and the other
completion functions is somewhat subtle, so it deserves a bit more
explanation.
* doc/lispref/minibuf.texi (Basic Completion)
(Programmed Completion): Add a few more remarks about nontrivial
completion boundaries.
Even for a trivial underlying completion table (where the 'boundaries'
action returns nil), we need to provide nontrivial boundaries so that
they match the behavior of 'all-completions'.
* lisp/minibuffer.el (completion-table-subvert): Return boundaries
even for trivial underlying completion table.
* test/lisp/minibuffer-tests.el (completion-table-subvert-test):
Amend unit test to also test boundaries. While there, also test
the other completion functions.
* lisp/erc/erc-backend.el (erc-session-client-certificate): New
buffer-local variable storing the TLS client certificate used for the
current connection.
(erc-open-network-stream): Use open-network-stream instead of
make-network-process, and pass any additional arguments to it.
(erc-server-connect): Add an optional client-certificate argument
that if present is passed with the :client-certificate keyword as part
of the arguments to erc-server-connect-function.
* lisp/erc/erc.el (erc-open): Add new optional client-certificate
argument, set it as erc-session-client-certificate, and pass it along
to erc-server-connect.
(erc): Clarify documentation string with respect to the full-name
argument.
(erc-tls): Add new client-certificate keyword argument and pass it in
the direct call to erc-open (instead of going through erc).
(erc-open-tls-stream): Pass any additional arguments (such as
:client-certificate) to open-network-stream. Also allow overriding
:nowait if desired.
* doc/misc/erc.texi: Add documentation for erc-tls, including the new
:client-certificate argument.
* etc/NEWS: Announce the change.
* lisp/progmodes/project.el (project-compilation-buffer-name-function):
New option.
(project-compile): Use it.
(project-prefixed-buffer-name): New function.
Copyright-paperwork-exempt: yes
* configure.ac (LD_SWITCH_SYSTEM_TEMACS) [mingw32]: Disable ASLR
when linking for unexec. Reported by Nikolay Kudryavtsev
<nikolay.kudryavtsev@gmail.com>.
* lisp/progmodes/project.el (project--find-regexp-in-files):
Don't unquote file names here.
* lisp/progmodes/xref.el (xref-matches-in-files): Do it here.
And only if the first element in the list is quoted (bug#47799).
Casting NULL is not a constant expression (Bug#47951).
* lib-src/seccomp-filter.c (main): Turn check for null pointer
representation into a runtime assertion.
* lisp/custom.el (custom-initialize-delay): Don't delay if
`custom-delayed-init-variables` has already been processed.
* lisp/startup.el (command-line): Mark `custom-delayed-init-variables`
as processed.
Also fix a bug where, with minibuffer-follows-selected-frame neither nil nor
t, a minibuffer could appear in two frames at the same time.
* src/window.c (Fset_window_configuration): Add a new &optional parameter
DONT-SET-MINIWINDOW, which inhibits the minibuffer from being restored from
the supplied window configuration.
(restore_window_configuration): Enhance to match the above.
* src/minibuf.c (read_minibuf): Enhance the argument list to the
restore_window_configuration calls to match the above. In the main case,
restoring the minibuffer is inhibited.
(read_minibuf_unwind): Should the frame with the expired minibuffer not be
found ("can't happen"), unwind the stacked data nevertheless, rather than just
exiting.
* src/keyboard.c (read_char_help_form_unwind): Amend a call of
Fset_window_configuration.
* doc/lispref/windows.texi (Window Configurations): Document the new form of
set-window-configuration.
* etc/NEWS (Lisp Changes in Emacs 28.1): Amend the entry for
set-window-configuration.
* lisp/isearch.el (isearch-update): When we start hscrolled,
consider also the case that point ends up being to the left of the
hscrolled window's edge. (Bug#46316)
In order to correctly detect the case of the "new style" with an empty body,
remove the old optional arguments `init-value`, `lighter`, and `keymap`,
so we can distinguish the "nil arg" from the "absent arg" cases.
* lisp/progmodes/cperl-mode.el (cperl-electric-else): Don't expand
scalar variables like '$continue' as keywords. (Bug#47902)
* test/lisp/progmodes/cperl-mode-tests.el
(cperl-test-hyperactive-electric-else): Verify that keywords are
expanded but variable names aren't.
The quoted-printable estimation was obviously wrong: the size becomes
smaller when decoded, not larger...
* lisp/mail/rmailmm.el (rmail-mime-set-bulk-data): Fix estimations
of decoded MIME attachment.
We used to `bset_enable_multibyte_characters` while the buffer is not
empty, putting the buffer temporarily in an inconsistent state.
Further simplifications along the way: Prefer re-using local var `histvar`
and let `insert` do the unibyte<->multibyte conversion if needed.
* lisp/minibuffer.el (minibuffer-mode): New derived mode.
* src/minibuf.c (syms_of_minibuf): New DEFSYMs Qminibuffer_mode,
Qminibuffer_inactive_mode, Qminibuffer_completing_file_name,
Qselect_frame_set_input_focus, Qadd_to_history.
(read_minibuf, set_minibuffer_mode, read_minibuf_unwind): Use the new DEFSYMs
in place of continual interning.
(set_minibuffer_mode): Put an active minibuffer into minibuffer-mode rather
than fundamental-mode.
* doc/emacs/mini.texi (Minibuffer Edit): Mention minibuffer-mode.
* doc/lispref/minibuf.texi (Intro to Minibuffers): Add a paragraph about
minibuffer-mode.
* etc/NEWS (Incompatible Lisp Changes in Emacs 28.1): Add an entry.
