* lisp/help-fns.el (help--symbol-completion-table): Be more
careful with `help-enable-completion-autoload` so we don't load
a package in cases where we already know it won't impact the result.
* lisp/files.el (save-some-buffers-action-alist): New M-~ entry.
(save-some-buffers):
* doc/emacs/files.texi (Save Commands):
* etc/NEWS: Document the new M-~ binding during C-x s.
* src/xdisp.c (display_min_width): Ignore 'min-width' display
specs which produce stretch glyphs wider than the window when
lines are truncated. (Bug#73600)
Teach term the difference between an unset foreground or
background color and a color that happens to match an existing
color. This way, when we insert text after a color
reset:(e.g. from an SGR0), we insert it without :foreground or
:background (whichever we've reset) face properties, allowing
that inserted text to inherit the colors of the underlying face.
This way, if we change, e.g., the background color of a buffer,
the background color of already-inserted text from the term
child changes along with that of the buffer instead of being
"locked" to whatever the background color of the buffer was at
the time the text was inserted.
This change aligns term.el with other terminal emulators.
* lisp/term.el (term-ansi-current-color):
(term--color-as-hex): track nil fg, bg colors
* lisp/help-fns.el (xref-backend-references):
New context-dependent override. Don't call project-current and
use elisp-load-path-roots directly (bug#69462).
(help-fns--setup-xref-backend): No need to set
project-vc-external-roots-function then.
* lisp/help-fns.el (help-fns--setup-xref-backend):
New function (bug#69462).
(describe-function, describe-variable): Use it here.

invalid values for the defcustom :local keyword.
* test/lisp/emacs-lisp/bytecomp-tests.el
(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.
`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.
* lisp/vc/diff-mode.el (diff-delete-other-hunks): New
command (bug#73387).
(diff-mode-map): Bind the new command to C-c RET n.
(diff-mode-menu): New entry for the new command.
(vc-next-action): Stop, and warn, if the user attempts to commit
a patch from a narrowed buffer (bug#73387).
* doc/emacs/files.texi (Diff Mode):
* etc/NEWS: Document the new command.
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)
* etc/ERC-NEWS: Announce removal of troublesome key binding first
introduced in ERC 5.6 as part of the `erc-fill-wrap' module.
* lisp/erc/erc-fill.el (erc-fill-wrap-mode-map): Remove key binding for
`erc-fill-wrap-cycle-visual-movement'.

when optional COUNT is nil.
(erc-track-modified-channels): Use new name for preferred face-finding
function.
(erc-track--get-faces-in-current-message, erc-track--collect-faces-in):
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.

add `erc-stamp--reset-on-clear' to `erc--pre-clear-functions'.
(erc-stamp-disable): Don't remove `erc-stamp--reset-on-clear' from
`erc--pre-clear-functions'.
(erc-stamp--find-insertion-point): Account for initial position being

(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'.
* lisp/erc/erc-truncate.el (erc-truncate-padding-size): New option to
help tamp down on disruptions when reading scroll back caused by overly
frequent truncation.

`erc-truncate--setup' to and from `erc-mode-hook', and run it when
needed.
(erc-truncate--buffer-size): New variable.
(erc-truncate--setup): New function.
(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.
* lisp/erc/erc.el (erc-mode): Add `erc--skip-past-headroom-on-clear'
to `erc--clear-function' in all ERC buffers.
(erc--with-spliced-insertion): Account for marker being `bobp'.
(erc--insert-before-markers-transplanting-hidden): Make more robust by
accommodating initial `point' possibly being `bobp'.

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.

update assertions, and use common helper.
(erc-scenarios-log--cmd-clear/left-stamps): New test.

(Bug#72736)
* etc/ERC-NEWS: Mention new function `erc-sync-banlist' in new section
for ERC 5.6.1.
* lisp/erc/erc-backend.el (erc-server-MODE): Don't call
`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".
