The doc string of 'frame-or-buffer-changed-p' says not to call it
with the nil argument, but term.el did. Since "M-x term" puts
'term--update-term-menu' on the 'menu-bar-update-hook' ahead of
'menu-bar-update-buffers', it caused the latter decide that there
was no change in buffers, because the internal state variable
used by 'frame-or-buffer-changed-p' when called with the nil
argument was reset by 'term--update-term-menu'. Fix that by using
a non-nil state variable.
* lisp/term.el (term--buffers-changed): New variable.
(term--update-term-menu): Use it when calling
'frame-or-buffer-changed-p'. (Bug#80231)
Some language servers request file watching for a very large number of
directories (e.g. Python virtualenvs), which can exhaust system
resources and cause slow startup.
https://github.com/joaotavora/eglot/issues/1568
* lisp/progmodes/eglot.el (eglot-max-file-watches): New variable.
(eglot--count-file-watches): New function.
(eglot--watch-globs): Use them to limit watches. Signal jsonrpc-error
when limit is reached.
(eglot-watch-files-outside-project-root): Fix docstring punctuation.
* etc/EGLOT-NEWS: Mention change.
Now also accepts file operation kinds as keys in the alist form.
* lisp/progmodes/eglot.el (eglot-confirm-server-edits): Rework
default value, docstring and defcustom type.
(eglot--confirm-server-edits): Also check for operation-kind-based
entries.
The current 2026 landscape suggests servers (especially gopls
and ocamllsp) take advantage of this, so let's give it to them
by default.
* lisp/progmodes/eglot.el (eglot-advertise-cancellation):
Default to t.
* etc/EGLOT-NEWS: Mention change.
If the user simply C-g's signal a 'jsonrpc-error' with code 32000 to
mean "no error", provide an LSP :failureReason and keep server chill.
* lisp/progmodes/eglot.el (eglot-handle-request<workspace/applyEdit>>):
Else, if the server asks us a question, the user has just 10
seconds to ponder, which is a bit silly.
* lisp/progmodes/eglot.el (eglot-execute): Pass timeout=nil to
eglot--request.
Previously, the default answer pre-filled in the minibuffer was
obscuring the other possible answers.
* lisp/progmodes/eglot.el
(eglot-handle-request<window/showMessageRequest>): Rework.
It was completely broken, with a cancel being set for every sent (and
probably already received) async request, and no actual discarding
of the response of a cancelled request.
* lisp/progmodes/eglot.el (eglot--async-request): Fix cancellation
of async requests.
(eglot--semtok-request): Don't need 'buf' &aux anymore.
Previously, 'quit' could cause remote endpoints to never get a
reply and thus sometimes hang. Ensure we always reply. Also,
give the application a chance to signal jsonrpc-error with the
served code=32000, meaning "no error".
* doc/lispref/text.texi (JSONRPC Overview): Rework section on
request dispatchers.
* lisp/jsonrpc.el (jsonrpc-connection-receive): Rework.
This allows clients such as Eglot to act on the user
C-g's/quits out of a blocking jsonrpc-request call. It also
fixes the TIMEOUT=nil passed to jsonrpc-request. An infinite
timeout in that case (for a long-running request, for example)
and it was not being transmitted to the lower
jsonrpc-async-request.
* lisp/jsonrpc.el (jsonrpc-request): Add CANCEL-ON-QUIT. Rework
docstring.
* lisp/window.el (quit-restore-window): Try to restore the
previously selected window only if WINDOW is either the selected
window or BURY-OR-KILL is neither 'burying' nor 'killing'.
Otherwise, this might deliberately change the selected window,
for example, when 'kill-buffer-quit-windows' is non-nil and WINDOW
shows the buffer to kill.
Using 'user-error' in 'hs-minor-mode', prevents the major-mode
from initializing correctly when hideshow is not supported in
that mode, using 'message' instead fixes this.
* lisp/progmodes/hideshow.el (hs-minor-mode): Tweak.
In async mode, the workaround for the old Terminal.app collides
with the binding we install for the primary DA. Just drop it.
* lisp/term/xterm.el (xterm--init): Remove workaround for very old
macOS `Terminal.app`.
This is in order to apply `browse-url-transform-alist'.
* lisp/net/browse-url.el (browse-url-with-browser-kind)
(browse-url-button-open, browse-url-button-open-url):
* lisp/net/shr.el (shr-browse-url):
* lisp/net/eww.el (eww-browse-with-external-browser):
* lisp/gnus/gnus-sum.el (gnus-summary-browse-url):
* lisp/emacs-lisp/package.el (package-browse-url): Let-bind
`browse-url-browser-function' and call `browse-url'.
* lisp/simple.el (goto-line, goto-line-relative): Add new arg 'interactive'.
Remove 'declare' with 'interactive-only'. Don't push the mark when called
non-interactively.
* lisp/net/tramp-adb.el:
* lisp/net/tramp-androidsu.el:
* lisp/net/tramp-integration.el:
* lisp/net/tramp-smb.el: Do not delay
`connection-local-set-profiles' until after loading `shell'.
* lisp/net/tramp-integration.el: Add the local profile for all
hosts listed in `tramp-local-host-names'.
* lisp/net/tramp.el (tramp-local-host-names): New defvar.
(tramp-local-host-regexp): Use it.
* test/lisp/net/tramp-tests.el (tramp-test03-file-name-defaults):
Adapt test.
* lisp/emacs-lisp/package.el (package-find-news-file): Abort
early if the package is built-in.
(describe-package-1): Do not invoke 'package-find-news-file' if
missing a package descriptor.
* lisp/emacs-lisp/package.el (package-review-policy): Move tags
to the cons-cell level, so that the labels are displayed in the
menu when inserting a new item.
* lisp/emacs-lisp/package.el (package-review)
(describe-package-1): Use new function.
(package-find-news-file): Add new function that also checks for
the "NEWS-elpa" file name.
These were in the wrong order anyway, so they never had any
effect.
* lisp/net/rcirc.el (rcirc-set-decode-coding-system)
(rcirc-set-encode-coding-system): Remove obsoletion aliases.
(Bug#80145)
'python-shell-get-process' is frequently called from
'python-eldoc--get-doc-at-point' and etc., invoking
'project-current' unless there is a buffer-specific Inferior
Python process. When the buffer is a remote buffer not
belonging to any project and has significant latency,
'project-current' may take a long time. To avoid this,
implement a process cache in 'python-shell-get-process'.
* lisp/progmodes/python.el (python-shell--process-cache)
(python-shell--process-cache-valid): New variables.
(python-shell--invalidate-process-cache): New function.
(python-shell-make-comint): Add a call to the above function.
(python-shell-get-process): Add process cache. (Bug#80045)
Previously, both the definition of __PYTHON_EL_get_completions
and the call to __PYTHON_EL_get_completions were sent to the
inferior Python each time
'python-shell-completion-get-completions' was executed.
However, there is no need to send the definition every time as
long as the definition remains unchanged. We improved this so
that the definition of __PYTHON_EL_get_completions is only sent
during the inferior Python initialization; it is no longer sent
during 'python-shell-completion-get-completions' execution.
* lisp/progmodes/python.el
(python-shell-completion-send-setup-code): New function.
(python-shell-first-prompt-hook): Add the above new function.
(python-shell-completion-get-completions): Omit sending
'python-shell-completion-setup-code'. (Bug#80182)
