* lisp/eshell/esh-var.el (eshell-var-initialize): ... and add to here,

* lisp/vc/vc.el (vc-default-checkin-patch):
Call vc-revert-file on buffer-file-name (vc-backend failed on
relative name sometimes). Delete the tmp dir after copying all
files back, not just the first one. Bug#52349,
https://lists.gnu.org/archive/html/emacs-devel/2022-10/msg01446.html.
This fixes bug #58534.
* lisp/progmodes/cc-engine.el (c-forward-type): Only regard "struct" keywords
which create self contained types (e.g. C++'s "typename") as creating found
types.
* lisp/progmodes/cc-langs.el (c-self-contained-typename-kwds
(c-self-contained-typename-key): New language consts and variable.
* lisp/menu-bar.el (menu-bar-edit-menu): Test buffer-read-only
before gui-backend-selection-exists-p. This places the less
expensive condition before the more expensive one.
* src/xfns.c (compute_tip_xy): Use cached monitor attributes
whenever available.
(Fx_show_tip): Remove code that really did nothing.
(Fx_backspace_delete_keys_p): Do not download the entire keymap
from the server upon creating a frame.
* src/xmenu.c (create_and_show_popup_menu): Use
x_translate_coordinates_to_root.
(x_menu_show): Use x_translate_coordinates_to_root.
* src/xselect.c (Fx_selection_exists_p): If a temporary
selection owner can be found, use it.
* src/xterm.c (x_translate_coordinates_to_root)
(x_handle_selection_monitor_event, x_find_selection_owner): New
functions. These functions try to avoid downloading data from
the X server in places that are called very often (i.e. during
tool bar updates.)
(handle_one_xevent): Handle selection notify events. Also catch
some mistakes found. Fetch all kinds of key names as well.
(x_create_special_window): New function.
(x_term_init, x_delete_display): Ask for all key names. Also,
passively monitor selections that are given to
`x-selection-exists-p' during redisplay, so we do not have to
ask the server about them upon each redisplay.
(syms_of_xterm): New variable `x-fast-selection-list'.
* src/xterm.h (struct x_monitored_selection): New structure.
(X_INVALID_WINDOW): New define.
(struct x_display_info): New fields for selection monitoring.
Also, record the fixes extension base.
* lisp/emacs-lisp/comp.el (native--compile-async): Don't start the
async compilation if we didn't add anything. This avoids spurious
"Compilation finished" messages in the *Async* buffer when it
turned out that all the files we considered nativecomping were
skipped.
* lisp/loadup.el (featurep): Define the hash table in nativecomp
builds (but not otherwise). A more natural place to define this
would be in comp.el, but comp.el isn't loaded yet when we load the
.elc file that updates comp--no-native-compile. We could change
the load order and move the definition to comp.el, though.
* lisp/emacs-lisp/bytecomp.el (byte-compile-from-buffer): Allow
inhibiting nativecomp earlier (bug#57627).
* lisp/emacs-lisp/comp.el (native-compile-async-skip-p): Use the data.
* lisp/emacs-lisp/cl-generic.el (cl-generic-define-method):
Preserve the `advertised-calling-convention`, if any (bug#58563).
* lisp/subr.el (declare): Warn when we hit this.
* lisp/emacs-lisp/byte-run.el (get-advertised-calling-convention): New fun.
* lisp/progmodes/elisp-mode.el (elisp-get-fnsym-args-string):
* lisp/help-fns.el (help-fns--signature):
* lisp/emacs-lisp/bytecomp.el (byte-compile-fdefinition): Use it.
* test/lisp/emacs-lisp/cl-generic-tests.el (cl-generic-tests--acc): New fun.
(cl-generic-tests--advertised-calling-convention-bug58563): New test.
* lisp/progmodes/python.el (python-shell-completion-at-point): Add
check if point is before line-start.
* test/lisp/progmodes/python-tests.el (python-shell-completion-shell-buffer-1)
(python-shell-completion-shell-buffer-native-1): New tests
(bug#58548).
* lisp/progmodes/python.el (python-shell-completion-at-point): Disable
completion in Python buffer when PDB is active in Python Shell buffer.
* test/lisp/progmodes/python-tests.el (python-shell-completion-pdb-1):
New test (bug#58562).
* lisp/emacs-lisp/loaddefs-gen.el (loaddefs-generate--emacs-batch):
Extract the autoloads and have them loaded along with loaddefs.el.
* etc/NEWS: Mention the new feature. (Bug#57639)
Give both the "" and _tag font-lock-function-name-face. Also correct the
fontification of an inherited class name when there is an attribute between
the class name being declared and the colon introducing the inheritance.
* lisp/progmodes/cc-engine.el (c-forward-over-colon-type-list): New function.
(c-forward-keyword-clause): Use the above new function instead of a
looking-at.
(c-forward-name, c-forward-declarator): Accept both the "" and the tag as part
of the name.
* lisp/progmodes/cc-fonts.el (c-font-lock-declarators): Fontify the "" (which
already has font-lock-string-face) and the tag with
font-lock-function-name-face.
* lisp/progmodes/cc-langs.el (c-overloadable-operators): Add "" to this list.
(c-sub-colon-type-list-re): New lang-const and lang-var.
