* lisp/erc/erc-goodies.el (erc-scroll-to-bottom): Only `recenter' when
the selected window's buffer is current. Previously, the module
`scrolltobottom' signaled an "Error in `post-command-hook'" when a
user clicked a channel indicator in the mode line from a window
showing another ERC buffer.
* lisp/erc/erc-track.el (erc-track--switch-fallback-blockers): New
internal variable used by `erc-track--switch-buffer' in deciding
whether to set `erc-track-last-non-erc-buffer' to the current buffer.
(erc-track--switch-buffer): Consult list of `buffer-match-p'
conditions in `erc-track--switch-fallback-blockers' to decide whether
to set `erc-track-last-non-erc-buffer' to the current buffer.
(Bug#63595)
* etc/ERC-NEWS: Tell module authors that `erc-display-message' can now
combine faces.
* lisp/erc/erc-button.el (erc-button--display-error-notice-with-keys):
Ask `erc-display-message' to compose `erc-notice-face' and
`erc-error-face'.
* lisp/erc/erc-match.el (erc-hide-fools): Merge `invisible' prop
`erc-match' with existing, if present, and move body to helper for
hiding matched messages.
(erc-match--hide-message): New helper function to hide messages
regardless of match type.
* lisp/erc/erc-track.el: (erc-track-faces-priority-list): Note in doc
string that faces reserved for critical messages are always
prioritized. Wrap :type declaration in macro helper to ensure
`erc-button' is loaded beforehand. Otherwise calling `setopt' with
the option's default value fails.
(erc-track--attn-faces): Add new internal variable for faces that
should always appear in the mode line, at least in the default client.
(erc-track-modified-channels, erc-track-face-priority): Prepend
`erc-track--attn-faces' to `erc-track-faces-priority-list'.
* lisp/erc/erc.el (erc-send-action): Ask `erc-display-message' to
apply both `erc-input-face' and `erc-action-face' to messages.
(erc--compose-text-properties): New internal variable to act as flag
for altering behavior of `erc-put-text-property'.
(erc--merge-prop): New function copied from `erc-button-add-face' for
general internal use with any text property by all of ERC.
(erc-display-message-highlight): Set fallback face to
`erc-default-face' the symbol instead of the string. For this to
break third-party code, callers would have to supply erroneous types
for nonexistent or undefined handlers and then explicitly check for
and depend on such misuse, which seems unlikely and therefore not
worth mentioning in etc/ERC-NEWS.
(erc-display-message): Explain how `type' param works when it's a
list. Fix code in type-as-list branch so that it optionally combines
faces instead of clobbers them.
(erc-put-text-property): Unalias from `put-text-property', but fall
back to the latter unless caller wants to combine faces, in which case,
defer to `erc--merge-prop'.
* test/lisp/erc/erc-button-tests.el
(erc-button--display-error-notice-with-keys): Expect a combined "error
notice" face. (Bug#64301)
* lisp/erc/erc-track.el (erc-track--switch-buffer): If the chosen
buffer has been killed, remove it from `erc-modified-channels-alist'
and try again.
* test/lisp/erc/erc-scenarios-misc.el
(erc-scenarios-base-kill-server-track): New test. (Bug#60560.)
* lisp/erc/erc-networks.el
(erc-networks--copy-server-buffer-functions): New internal hook
through which modules can perform housekeeping when server buffers
belonging to the same network context are merged.
(erc-networks--copy-over-server-buffer-contents): Run new internal
hook `erc-networks--copy-server-buffer-functions'.
* lisp/erc/erc-track.el (erc-track-enable, erc-track-disable): Manage
membership in `erc-networks--copy-server-buffer-functions' hook.
(erc-track--replace-killed-buffer): New function to replace server
buffer being killed in `erc-modified-channels-alist'.
* test/lisp/erc/erc-scenarios-base-association.el
(erc-scenarios-networks-merge-server-track): New test.
* test/lisp/erc/resources/networks/merge-server/track.eld: New test
data. (Bug#60560.)
* lisp/erc/erc.el (erc-default-recipients, erc-default-target):
Explain that the variable has fallen out of favor and that the
function may have been used historically by third-party code for
detecting channel subscription status, even though that's never been
the case internally since at least the adoption of version control.
Recommend newer alternatives.
(erc--current-buffer-joined-p): Add possibly temporary predicate for
detecting whether a buffer's target is a joined channel. The existing
means are inconsistent, as discussed in bug#48598. The mere fact that
they are disparate is unfriendly to new contributors. For example, in
the function `erc-autojoin-channels', the `process-status' of the
`erc-server-process' is used to detect whether a buffer needs joining.
That's fine in that specific situation, but it won't work elsewhere.
And neither will checking whether `erc-default-target' is nil, so
long as `erc-delete-default-channel' and friends remain in play.
(erc-add-default-channel, erc-delete-default-channel, erc-add-query,
erc-delete-query): Deprecate these helpers, which rely on an unused
usage variant of `erc-default-recipients'.
* lisp/erc/erc-services.el: remove stray `erc-default-recipients'
declaration.
* lisp/erc/erc-backend.el (erc-server-NICK, erc-server-JOIN,
erc-server-KICK, erc-server-PART): wrap deprecated helpers to suppress
warnings.
* lisp/erc/erc-join.el (erc-autojoin-channels): Use helper to detect
whether a buffer needs joining. Prefer this to server liveliness, as
explained above.
* lisp/erc/erc-track.el (erc-track-modified-channels): Fix what is a
probable bug when a new insert event happens for a buffer that was not
tracked or for which no mode line face was selected: in this case,
stop treating the latest buffer's face (first in list) as the previous
one, which could be overridden with an older one (in FACES' rest), as
if it had happened after.
* lisp/erc/erc-track.el (erc-track-find-face): Declare obsolete and
rewrite as 'erc-track-select-mode-line-face', changing the function
arguments, so that it is very clear what the current algorithm is.
No functional changes. Performance improvements. Clarify the
documentation and remove the part on some faces being lists, which
clearly does not apply.
(erc-track-modified-channels): Replace calls to 'erc-track-find-face'
with calls to 'erc-track-select-mode-line-face', preserving the
existing behavior.
(erc-modified-channels-alist): Change the reference to
'erc-track-select-mode-line-face' in the documentation following the
rename.
* etc/NEWS: Announce the change.
Co-authored-by: Amin Bandali <bandali@gnu.org>

(erc-make-mode-line-buffer-name): Describe exactly the algorithm, and
reference custom variables that influence it.

`erc-track-switch-buffer', but uses `switch-to-buffer-other-window'
instead, to open the buffer in another window.
Restore lines saying "Maintainer: emacs-devel@gnu.org" when there is
no special maintainer for a file. Although this wasn't documented
it was common practice and removing the lines didn't have consensus.

descriptions of 'window-pixel-height-before-size-change' and
'window-pixel-width-before-size-change' to Window Hooks
