28.0.50; ERC now ignores dialed server names in autojoin


From: J.P.
Subject: 28.0.50; ERC now ignores dialed server names in autojoin

Tags: patch

A recent addition [1] to ERC (and now Emacs 28) introduced a breaking
change that's set to create some churn for (what I suspect will be) a
noticeable swath of ERC users. First off, this is solely my fault
because I advocated for this addition without envisioning, much less
trying to forestall, the coming disruption [2].

What this boils down to is that folks with an entry like
("irc.libera.chat" "#libera") in their `erc-autojoin-channels-alist'
will find that it no longer works because ERC now matches against what's
called the "announced" name (e.g., "foo.libera.chat") rather than the
"dialed" name ("irc.libera.chat" or "localhost" or "my.vps.net") [3].

Anyway, apologies for the delay in bringing this to the tracker [4]. The
attached patch attempts to right the offending portions while preserving
the benefits introduced by [1], which I still believe to be significant.
Please direct your daggers toward me and not [1]'s author. Thanks.

P.S. Tests for this reside in #48598.


Notes
~~~~~

[1] commit 9bb8d90cddf11df3aecdc6c04e762773dfa0cb92
    Allow irc network symbols in erc-autojoin-channels-alist

[2] I suppose I've been so preoccupied with whining about the underlying
    problem this exposes (mostly in my progress reports for #48598) that
    I neglected to confront the reality of [1] becoming the last word on
    join-related business for a good while. IOW, having #48598's patch
    set build on [1]'s changes while believing wholeheartedly that both
    would make it into 28 was classic hubris on my part in that it drove
    me to "forget" to consider what would happen if the two ever found
    themselves on opposite sides of a release divide. Which they have.

[3] In reality, "announced" is favored only when set, which is basically
    always because the 004 handler runs right on the heels of connection
    registration. For anyone who cares, kensanata added the fallback in
    2005, right around when `erc-announced-server-name' became
    `erc-server-announced-name'.

    BTW, this new reorienting toward the "announced" name isn't actually
    the focus of [1], which is more about elevating network names to
    equal footing. And it isn't really "new" at all but more like a
    restoration of what's historically been the preferred (and, from
    2001 to 2005, only) means of referring to an IRC session. Only in
    the last few years or so has ERC actually been conflicted in this
    regard.

[4] For a couple weeks now, I've been trying to reach out to the person
    who initially brought this to our attention on Libera, but that's
    become a lost cause. I mainly wanted to confirm that their
    suspicions of this being an Emacs-29-only thing were in fact wrong,
    which I'm now certain of.
