* lisp/textmodes/flyspell.el (turn-on-flyspell): Make into obsolete
function alias for 'flyspell-mode'.
(turn-off-flyspell): Declare obsolete.
(text-mode-hook): Don't redundantly set :options here.
* lisp/textmodes/text-mode.el (text-mode-hook): Prefer 'flyspell-mode'
to 'turn-on-flyspell' in :options. (Bug#76535)
Earlier versions of Emacs were limited to at most 32 subprocesses or
network connections on Windows due to the 64-object limit imposed by
WaitForMultipleObjects. To overcome this, a simple waiting thread
pool is implemented, allowing Emacs to efficiently wait on up to
2048 objects.
Each thread in the pool can wait on up to 63 objects, and a total of
32 threads are used, together with the main thread, to expand the
waiting capability. This enables Emacs to support approximately 1024
subprocesses, which is comparable to the 'pty' method on GNU/Linux
when using the default FD_SETSIZE of 1024.
To minimize overhead, the threads remain active instead of being
frequently created and destroyed, reducing unnecessary system
resource consumption. Idle threads can be terminated after a
period of inactivity to free up memory.
* src/w32.h (FD_SETSIZE): Change from 64 to 2048.
* src/w32.c (term_ntproc): Call 'free_wait_pool' to free waiting
threads.
* src/w32proc.c (WFO_ABANDONED, WFO_TIMEOUT, WFO_FAILED)
(WFO_MAX_WAIT): New macros.
(wait_objects_context, wait_objects_pool, wait_objects_info):
New structures for managing the thread pool.
(wait_objects_pool, wait_objects_info): New static variables for
managing the thread pool.
(wait_objects_thread, start_wait_objects, stop_wait_objects)
(end_wait_and_return, shrink_wait_pool, free_wait_pool):
New functions for waiting and managing the thread pool.
(wait_for_objects, msg_wait_for_objects): New functions as
replacements for WaitForMultipleObjects and
MsgWaitForMultipleObjects.
(wait_pid): Use 'wait_for_objects' and new macros.
(sys_select): Make some variables static to avoid stack
allocation. Use 'wait_for_objects', 'msg_wait_for_objects', and
the new macros.
* lisp/isearch.el (isearch-yank-x-selection): Ignore errors
signaled by 'gui-get-primary-selection', to better emulate what
'gui-get-selection' was doing. In particular,
'gui-get-primary-selection' can signal an error on MS-Windows.
* configure.ac (systemduserunitdir): New variable and option.
* Makefile.in (systemduserunitdir): New, set by configure.
(install-etc, uninstall): Don't install emacs.service when
systemduserunitdir is unspecified.
* etc/NEWS: Announce the new configure option. (Bug#76924)
The previous fix fixed the problem that treesit-parser-create
always use the current buffer, but that introduce another subtle
problem: if an indirect buffer creates a parser, the parser
saves the base buffer rather than the indirect buffer. In Emacs
29, if you create a parser in an indirect buffer, the parser
saves the indirect buffer. This change of behavior breaks some
existing use-cases for people using indirect buffer with
tree-sitter.
In Emacs 31, indirect buffers and base buffer get their own
parser list, so this problem doesn't exist anymore. The fix is
only for Emacs 30.
* src/treesit.c (Ftreesit_parser_create): Use the buffer that's
given to treesit-parser-create, even if it's an indirect buffer.
* lisp/treesit.el (treesit-forward-sentence): When no more
sentences are found, move to the end of the buffer or to
the range boundary at the 'treesit-parser' overlay's end.
* lisp/rect.el (rectangle-indicate-zero-width-rectangle): New user
option.
(rectangle--highlight-for-redisplay): Use it to decide whether to
indicate empty rectangles on display. (Bug#16403)
* etc/NEWS: Announce the feature.
* lisp/textmodes/remember.el (remember-initial-major-mode):
Major mode for remember buffer.
(remember-data-files-regex): Regular expression to filter files.
(remember-append-in-data-directory): Handler to append data to
files.
(remember-mode): Change to a minor mode.
(remember-prefix-map): New. (Bug#75543)
* lisp/time-stamp.el (time-stamp-string-preprocess): Move all of the
big 'while' loop to the end of the function, to better expose its
structure of iterating over the format string.
* lisp/emacs-lisp/find-func.el (find-function-mode): When
find-function-mode-lower-precedence is non-nil, apply the
bindings in such a way that we can also remove them when the
mode is deactivated. Approach due to Stefan Monnier.
* doc/lispref/variables.texi (File Local Variables):
<hack-local-variables>: Say that it applies directory-local
variables too. Add a cross-reference.
(Directory Local Variables): Document dir-local-variables-alist.
* lisp/files.el (hack-local-variables): Say that it always puts
into effect directory-local variables.
* lisp/erc/erc-compat.el (erc-compat--xml-escape-string): New macro to
call `xml-escape-string' sans the NO-ERROR argument on Emacs 27.
* lisp/erc/erc-desktop-notifications.el (erc-notifications-notify): Use
compat macro.
* lisp/erc/erc-log.el (erc-truncate-buffer-on-save): Use
`make-obsolete-variable' because `erc-truncate-buffer-on-save' is an
option, not a function. Already mentioned in etc/ERC-NEWS.
(erc-logging-enabled): Return nil if `log' appears in the `erc--skip'
msg prop.
* lisp/erc/erc-stamp.el (erc-stamp--defer-date-insertion-on-post-modify):
Add `log' to `erc--skip' msg prop. This tells the log module to defer
advancing the `erc-last-saved-position' marker until after stamps have
been inserted, thus ensuring they're included in logs when
`erc-log-write-after-insert' is non-nil.
* test/lisp/erc/erc-scenarios-log.el
(erc-scenarios-log--save-buffer-in-logs/truncate-on-save): Suppress
warning for `erc-truncate-buffer-on-save'.
(erc-scenarios-log--write-after-insert): New test. (Bug#76875)
