(bytecomp-test-defcustom-local): New test.
* lisp/custom.el (custom-declare-variable): Make the :local keyword
accept the symbol 'permanent-local', meaning that the variable is
permanent but not marked as automatically buffer-local.
(defcustom):
* doc/lispref/customize.texi (Variable Definitions): Document the
above change.
* test/lisp/custom-tests.el
(custom-tests-defcustom-:local-keyword): New test.

(lua-ts-send-file, lua-ts-send-region): Mark inferior interaction
commands that are only relevant in Lua buffers. (Bug#73586)
`package-initialize` is used to initialize the whole machinery needed
to list/download/install/remove packages, whereas here we only need to use
the installed packages.

In 'M-x customize', Eglot fits in better in "Programming -> Tools", with
the likes of Flymake and Gud, than it does in "Applications", with ERC
and Newsticker.
* lisp/progmodes/eglot.el (eglot): Change :group of defgroup to 'tools'.
* lisp/progmodes/python.el: Remove out-of-date documentation about
automatic indentation; 'electric-indent-mode' is enabled by default in
Emacs 24.4 or later, so this is no longer an issue.
When _FORTIFY_SOURCE is defined mingw-w64 provides an inline definition
of read in io.h. This makes our previous redirection to sys_read
ineffective. The prototype of sys_read is now required because we don't
touch the prototype of read.
* nt/inc/ms-w32.h (read): Move the redirection after io.h. Add prototype
for sys_read (Bug#73444)
* lisp/eshell/esh-var.el (eshell/env): Throw 'eshell-replace-command' as
needed.
* test/lisp/eshell/esh-var-tests.el
(esh-var-test/local-variables/env/no-locals): New test (bug#73479).

when optional COUNT is nil.
(erc-track-modified-channels): Use new name for preferred face-finding
function.

Rename former to latter to better reflect expanded utility, which now
includes spanning gaps, including newlines and indentation that may be
lacking in face-related properties.
* test/lisp/erc/erc-track-tests.el (erc-track--collect-faces-in): New
test. (Bug#73443)
* etc/ERC-NEWS: Entry mentioning `erc-keep-place-indicator-truncation'.
* lisp/erc/erc-goodies.el (erc-keep-place-indicator-truncation): New
option. Something like this should have accompanied the module's
introduction.
(erc-keep-place-indicator-mode, erc-keep-place-indicator-enable)
(erc-keep-place-indicator-disable): Arrange to take necessary measures
to avoid losing the indicator on `erc--clear-function'. This module was
first introduced by bug#59943.
(erc--keep-place-move-hook): New variable.
(erc--keep-place-indicator-adjust-on-clear): New function.
(erc-keep-place-move): Try to ensure the overlay resides at the
beginning of a message. Run hook `erc--keep-place-move-hook'.
* test/lisp/erc/erc-scenarios-keep-place-indicator-trunc.el: New file.
* test/lisp/erc/erc-scenarios-keep-place-indicator.el
(erc-scenarios-keep-place-indicator--follow): Fix missing test
description. (Bug#72736)
* etc/ERC-NEWS: Mention option `erc-truncate-padding-size'.
* lisp/erc/erc-fill.el (erc-fill-wrap-mode, erc-fill-wrap-enable)
(erc-fill-wrap-disable): Manage membership in the `erc--clear-function'
advice stack for own function that massages a buffer's oldest inserted
message, post truncation.
(erc-fill--wrap-massage-initial-message-post-clear): New function.
* lisp/erc/erc-log.el (erc-log-mode, erc-log-enable): Don't add
`erc-save-buffer-in-logs' to `erc--pre-clear-functions'. Use local
advice around common interface variable instead, as noted below.
(erc-log-disable): Likewise, don't remove `erc-save-buffer-in-logs' from
`erc--pre-clear-functions'.
(erc-log-setup-logging): Add `erc-log--save-on-clear' to
`erc--clear-function'.
(erc-log-disable-logging): Remove `erc-log--save-on-clear' to
`erc-clear-function'.
(erc-save-buffer-in-logs): Abort when `erc--insert-marker' is non-nil.
(erc-log--save-on-clear): New function, a thin wrapper around
`erc-save-buffer-in-logs', adapting it to the `erc--clear-function'
advice interface.

from `erc--clear-function' advice stack.
(erc-stamp--redo-right-stamp-post-clear): New function.
(erc-stamp--update-saved-position): Remove unused function. This was
originally added along with `erc-stamp--reset-on-clear' as part of
bug#60936.
(erc-stamp--reset-on-clear): Expect end of truncation boundary to be at
`erc-insert-marker'. Rework to use new `erc--clear-function' interface
and run on `erc-timer-hook' instead of `erc-insert-done-hook'.

help tamp down on disruptions when reading scroll back caused by overly
frequent truncation.

(erc-truncate-buffer-to-size): Guard execution with
`erc-truncate--padding-size' and `erc--inhibit-clear-p'. Reflow for
readability, removing obsolete comments. Call hooks with marker instead
of buffer position, as per the new `erc--clear-function' interface.
(erc-truncate-buffer): Defer execution to `erc-timer-hook' when running
post-insertion via a response handler.
(erc-truncate--inhibit-when-local-and-interactive): New function.

interface to replace `erc--pre-clear-functions'.
(erc--pre-clear-functions): Remove unused variable.
(erc--skip-past-headroom-on-clear): New function.
(erc--inhibit-clear-p): New variable.

`erc-banlist-update'.
* lisp/erc/erc-fill.el (erc--determine-fill-column-function): New
method for `fill' and `fill-wrap' modules.
* lisp/erc/erc-pcomplete.el (pcomplete/erc-mode/BANLIST)
(pcomplete/erc-mode/BL)
(pcomplete/erc-mode/MASSUNBAN, pcomplete/erc-mode/MUB):
New functions.
* lisp/erc/erc.el: Map ERC 5.6.1 to Emacs 31.1 in
`customize-package-emacs-version-alist'.
(erc-channel-banlist): Deprecate practice of using the symbol property
`received-from-server' of as a state flag because it's error-prone and
bleeds into other connections.
(erc--channel-banlist-synchronized-p): New variable to indicate
whether the ban list has been initialized. The presence of a local
binding for `erc-channel-banlist' could probably be used for the same
purpose but would surely require rewriting `erc-cmd-BANLIST' and
`erc-cmd-MASSUNBAN'.
(erc-sync-banlist): New function, announced in ERC-NEWS.
(erc--wrap-banlist-cmd): New function.
(erc-banlist-fill-padding): New variable.
(erc--determine-fill-column-function): New generic function.
(erc-cmd-BANLIST): Move forward declaration of `erc-fill-column' from
top level into function body. Always reset `received-from-server' to
nil. Improve column calculations.
(erc-cmd-MASSUNBAN): Always reset `received-from-server' to nil.
(erc-banlist-finished): Deprecate function unused since 2003.
(erc--banlist-update): New function.
(erc-banlist-update): Deprecate function because its logic is faulty
and it doesn't handle mixed mode letters, like "MODE #foobar
+mb *@127.0.0.1". See https://modern.ircdocs.horse/#mode-message. It
also depends on an obsolete convention regarding the symbol property
`received-from-server' of `erc-channel-banlist'. Basically, this
function used to run upon receipt of any "MODE" command from the
server. However, actual updates to the variable `erc-channel-banlist'
only happened if `received-from-server' was t, which could only be the
case after the user issued a /MASSUNBAN. And that behavior was
determined to be a bug. This mode framework stuff was introduced as
part of bug#67220 for ERC 5.6.
(erc--handle-channel-mode): New function, a method for standard
channel-mode letter "b".
* test/lisp/erc/erc-tests.el (erc--channel-modes)
(erc--channel-modes/graphic-p): Assert contents of
`erc-channel-banlist' updated on "MODE". (Bug#72736)
* lisp/erc/erc-backend.el (erc--parsed-response): New variable to be
the internal version of the ancient `erc-message-parsed', which is
only available during `erc-display-message', and therefore of somewhat
limited utility.
(erc-call-hooks): Bind `erc--parsed-response' to the parsed
`erc-response' object for the duration of its handling. Bind
`erc--msg-prop-overrides' around all hooks to allow response handlers
to influence inserted msg props for any `erc-display-message' calls.
(Bug#72736)
* lisp/erc/erc.el (erc--msg-props): Mention that the `erc--spkr'
msg-prop value is taken from the `nickname' slot of the user's
`erc-server-users' entry.
(erc--speakerize-nick): Avoid using the provided NICK parameter for
the `erc--spkr' property. Instead, use the version from the
`nickname' slot of its `erc-server-users' item, which is itself an
`erc-server-user' object. These text props were originally introduced
in ERC 5.6 as part of bug#67677.
* test/lisp/erc/erc-tests.el (erc--refresh-prompt)
(erc--check-prompt-input-functions, erc-send-current-line)
(erc--check-prompt-input-for-multiline-blanks)
(erc-send-whitespace-lines): Use more convenient helper utility to
create fake server buffer where possible.
(erc--speakerize-nick): New test.
* test/lisp/erc/resources/erc-tests-common.el
(erc-tests-common-make-server-buf): Don't use ERT temp buffer's name
for dialed server, etc., because it contains unwanted chars.
(erc-tests-common-with-process-input-spy): Defer to each test to set
up its own prompt, etc. (Bug#72736)
Prefer whatever version of Python that "python" might point to; use
"python3" if it doesn't exist. On recent versions of typical GNU/Linux
distributions, "python" either does not exist or it points to Python 3.
In (presumed rare) cases where "python" points to Python 2 instead,
users are now expected to manually customize these variables if they
want to use Python 3.
* lisp/progmodes/python.el (python-interpreter)
(python-shell-interpreter): Prefer "python" to "python3".

It was an old alias for :inverse-video that hasn't worked very well for
many years.

(Finternal_set_lisp_face_attribute_from_resource)
(Finternal_get_lisp_face_attribute)
(Finternal_lisp_face_attribute_values, syms_of_xfaces):

* etc/NEWS: Announce.
This attribute keyword has been non-working in defface for 14 years,
thus warning about it is both safe and decent.
* lisp/emacs-lisp/bytecomp.el (bytecomp--check-cus-face-spec):
Warn and suggest :inverse-video to be used instead.
* test/lisp/emacs-lisp/bytecomp-tests.el (bytecomp-test-defface-spec):
Add a test case.
* etc/NEWS: Notify the user.
When dealing with exceptionally large Git repositories, the
performance of `project-find-file` can suffer dramatically as
the list of files is collected for completion. This adds insult
to injury when you consider cases where the developer has
configured the repository to use a sparse checkout where the
vast majority of these files are not even present on disk and
are not valid candidates for completion.
* lisp/progmodes/project.el (project--vc-list-files):
Pass 'sparse' to 'git ls-files' when Git is recent enough.
Filter out file names that end with '/' (bug#73320).
