We support Emacs 24.4 and later (for ELPA releases), and ad-find-advice
only changed from a macro to a function in Emacs 27, so this change is
to restore compatibility with older versions where we do need the macro
definition loaded at byte-compilation time.
This effectively combines the related changes from:
- commit 986c12b20f
- commit c221db0402
Speedbar now can be opened in a window instead of a separate frame. The
frame remains the default.
* doc/emacs/frames.texi: Mention Speedbar window mode.
* doc/misc/speedbar.texi: Document 'speedbar-window'.
* lisp/speedbar.el
(speedbar-prefer-window): New user option. If t, the command `speedbar'
open the speedbar in a window.
(speedbar-window-dedicated-window): New user option. If t the window is
dedicated.
(speedbar-window-side): New user option. The side of 'speedbar-window',
defaults to left.
(speedbar-window-default-width): New user option. The default size of
the 'speedbar-window'.
(speedbar-window-max-width): New user option. Limits the width of the
'speedbar-window'. The user can resize the window as desired, but this
option will be the width of the window when restored.
(speedbar--buffer-name): New variable, the buffer name used for both
'speedbar-frame-mode' and 'speedbar-window-mode'.
(speedbar--window): New variable, the window displaying 'speedbar-window'.
(speedbar--window-width): New variable, store the current width of
'speedbar-window'.
(speedbar-easymenu-definition-trailer): Now it is a function that
returns a different trailer for 'speedbar-frame' and 'speedbar-window'.
(speedbar): Now it is a function that calls 'speedbar-frame-mode', the
default or 'speedbar-window-mode' based on the value of
'speedbar-prefer-window'.
(speedbar-frame-mode): Before opening a frame, close 'speedbar-window'
if it is open.
(speedbar-frame-or-window): New function, returns 'frame', 'window'
or nil if speedbar is not open.
(speedbar-window): New alias for 'speedbar-window-mode'.
(speedbar-window-mode): Enable of disable 'speedbar-window'.
(speedbar-window--window-live-p): New function, return non-nil if the
'speedbar-window' is live.
(speedbar-window--buffer-live-p): New function, return non-nil if the
'speedbar-buffer' is live.
(speedbar-window--live-p): New function, return t if 'speedbar-window'
is open.
(speedbar-window-current-window): New function, return t if the selected
window is speedbar-window.
(speedbar-window--close): New function, close the 'speedbar-window'.
(speedbar-window--width): New function, return the current width of
'speedbar-window'.
(speedbar-width): New function, return the 'speedbar' of
'speedbar-frame-mode' of 'speedbar-frame-mode'.
(speedbar-set-mode-line-format): Use the new 'speedbar-width' function.
(speedbar-directory-buttons): Use the new 'speedbar-width' function.
(speedbar--speedbar-live-p): New function, returns t if

'speedbar-window-mode'.
* doc/lispref/commands.texi (Click Events): Mention menu-bar.
* lisp/mouse.el (mouse-event-areas-with-no-buffer-positions):
New defvar including all areas mentioned in the Lisp reference.

(winner-mode-map): Use defvar-keymap.
* test/lisp/winner-tests.el: New file.
* lisp/cedet/pulse.el: Move from here...
* lisp/pulse.el: ...to here. This library is no longer relevant only
to CEDET. It is used by other built-in libraries, GNU ELPA packages,
and very likely third-party libraries too.
* lisp/dired.el (dired-copy-filename-as-kill): Support new value
of ARG, to mean file name relative to project root (bug#76792).

* 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)
