This could be considered a feature request. Because I have not used
Emacs in this way before, so I don’t know what was the behaviour
earlier. Here is what happens,
1. emacs -Q
2. C-x 5 2
3. (setq erc-autojoin-channels-alist '(("libera.chat" "#emacs" "#erc" "#gnus")))
4. M-x erc-tls ; with following parameters - (irc.libera.chat, 6697,
nickname, password)
5. While it is connecting to the server, switch to the other frame to
work on other stuff
Result: After the ERC connects to the server, it opens the autojoin
channels in the current frame. Ideally, it should open the channels in
the (dedicated) original frame where ERC was launched.

This is somewhat related to bug#51753 -- how erc handles these buffer
actions should be changed in general.

Thanks. Setting the value of erc-join-buffer to ’bury is a good
workaround. Found in that bug discussion.
What is the control command for marking the bug as duplicate? I couldn’t
locate such a command in "debbugs" package.

It's "forcemerge" -- it should be available in the debbugs-gnu package;
it's what I use for merging/closing/reopening bug reports.

Are you saying ERC ought to remember the frame in which an entry-point
command, like `erc-tls', was originally invoked? Or might it be enough
to make a best effort attempt at finding such a "dedicated" frame?
If it's door #2, what if we used the first frame found containing a
buffer belonging to the same connection (and if no such frame exists,
just leave it up to the display-buffer gods)? This way, we could rely
more fully on window.el facilities and avoid having to wrangle yet more
state. Or, if really necessary, we could maybe fall back on a strategy
that uses `window-prev-buffers' (or whatever) to find the most recently
used frame for that connection (overkill, IMO). Either way, any solution
would need to address not just autojoined channels but also
server-initiated JOINs, PMs, etc.
The attached patch claims to do something like I've described. If you're
able to try it, please set these options beforehand:
(setq erc-join-buffer 'frame
erc-auto-query 'frame
erc-query-display 'frame
erc-reuse-frames 'displayed)
If you're unable to try it, please let me know, and I can maybe add it
temporarily to one of ERC's installable bug packages.
Thanks,
J.P.

Subject: [PATCH] Allow erc-reuse-frames to favor connections
* lisp/erc/erc.el (erc-reuse-frames): Add alternate value to favor
existing frames already displaying other buffers from the same
connection.
(erc-setup-buffer): Add case for "displayed" variant of
`erc-reuse-frames'.

I have tried the #2 as specified below. I kind of agree that #1 will
result in the desired behaviour.

I tried this and here is what is happening.
I launched emacs then I launched another frame and M-x erc-tls and come
back to the 1st frame for other work. "erc-tls" running fine in the
other frame but when it starts to join autojoin channels after
connecting, it creates one more frame for each channel instead of
reusing the 2nd frame.

Thanks for trying out that patch. Basically, I bungled a few things that
prevented it from faithfully representing #2, even though I claimed
otherwise (sorry). IOW, I'm saying the approach may be salvageable and
only the implementation flawed.

Right, it seems I blindly fixated on the segregation aspect of your
description (again, apologies) and glossed over the obvious fact that
you don't want ERC creating frames, period. I've adapted the existing
patch with this in mind in hopes you're willing to try again.
One thing to be aware of is that even if we pivot to #1, the
connection-detection and buffer-association stuff will still be
unreliable in many cases. However, that should change after bug#48598
lands. That said, if you still feel strongly about #1, then please say
so (others following along as well). And likewise if you have
suggestions on the implementation or would like to try taking the wheel.
Thanks.

The changes I was referring to have been on HEAD for over a month now,
but I've been slow in getting back around to this bug (sorry). In case
you or anyone else is interested, I've reworked things a bit to leverage
the new buffer-association stuff, which should make finding a suitable
frame more reliable. You still have to set the options as initially
described up thread. Thanks.

Subject: [PATCH 1/1] Allow erc-reuse-frames to favor connections
* lisp/erc/erc.el (erc-reuse-frames): Add alternate value to favor
existing frames already displaying buffers from the same connection.
(erc--setup-buffer-first-window, erc--display-buffer-use-some-frame):
Add helpers to support 'display' variant of `erc-resuse-frames'
(erc-reuse-frames, erc-tests--servars, erc-tests--assert-server-split,
erc-tests--erc-reuse-frames, erc-tests--run-in-term): Add test case
and supporting helpers. (Bug#55540)

I will try this change tomorrow, and report. Thanks for the
updated. Thanks for your work.

erc still pops up the buffer by default, I think? I don't think it
should do that, because it's both pretty annoying and a security
issue -- you may suddenly be typing a password into an erc buffer.

Are you concerned about the behavior during initial connections as well
as automatic reconnections? Regardless, as you say, the default value of
`buffer' for `erc-join-buffer' (and `erc-reconnect-display') causes the
buffer in the selected window to be replaced with the
just-(re)initialized ERC buffer.
Also, depending on various factors, values other than `buffer' can
exhibit similar behavior. For example, in a dual-window split, a value
of `window-noselect' can result in a newly (re)joined channel replacing
the buffer in the selected window when the connection's server buffer is
showing in the other window. Plain `window' is much the same, but at
least there's somewhat of an expectation that the selected window's
buffer may change.
Really, the only safe option is `bury' (well, maybe also the proposed
frame stuff in Pankaj's patch, but only when an extra, ERC-specific
frame already exists, which we can't count on). That said, there's no
reason we'd have to stick with existing options/behavior when choosing a
new default. I guess it just comes down to what users want to happen.
If we're talking both `erc-join-buffer' and `erc-reconnect-display', one
idea would be to make `window-noselect' the default but change it to
mean the selected window is always left unmolested, no matter what. The
justification for the breaking change would be that the existing doc
string in
(const :tag "Split window, don't select" window-noselect)
has always implied as much, namely that a window displaying the new
buffer will always be shown and never selected.
Although, if this only concerns `erc-reconnect-display', we could just
go with `bury' since (among the available options) that best minimizes
the disruption of a reestablished connection.
Hopefully folks have stronger opinions and/or better ideas. Thanks.

I think the default action should be to do nothing to the window setup
at all, and just add the notification to the mode line.

I believe changing the default for `erc-join-buffer' (alone) to `bury'
is the easiest way to achieve that.
Thus, if no one objects within the next week or so, I will add the patch
below or similar to trunk (and what will become ERC 5.5), along with a
related NEWS entry. Thanks.

Now the behaviour is acceptable when "erc-autojoin-channels-alist" is
set to nil. i.e. the frame in which I launched "erc-tls" opens the erc
window instead of occupying the current frame.
But when I have few channels in "erc-autojoin-channels-alist" then the
channels are still openning in the current frame instead of the
dedicated frame that I started for "erc-tls". Is there some setting that
I missed in the conversation for this? My current "erc" related
settings are:
--8<---------------cut here---------------start------------->8---
(setq erc-prompt-for-password nil
erc-prompt (lambda () (concat "[" (buffer-name) "]")))
(eval-when-compile (require 'erc-services))
(setq erc-prompt-for-nickserv-password nil
erc-use-auth-source-for-nickserv-password t)
(setq erc-server "irc.libera.chat")
(setq erc-port 6697)
(setq erc-nick "my-nick")
(setq erc-user-full-name "My Full Name")
(eval-when-compile (require 'erc-join))
(setq erc-autojoin-channels-alist
'(("libera.chat" "#emacs" "#erc" "#gnus")))

Hm, right, but I think that was always the baseline behavior, no? If
not, I wonder if the recent change to the default for `erc-join-buffer'
somehow affected this.

Looks like it, but I should have re-summarized either way. So that's my
bad.
> (setq erc-prompt-for-nickserv-password nil
> erc-use-auth-source-for-nickserv-password t)
This is unrelated (so feel free to skip ahead), but are you sure
auth-source is even being consulted here? I ask because `services' isn't
a default module, and your snippet doesn't modify `erc-modules', AFAICT.
Regardless, adding services to the repro mix at this point would only
complicate matters, so please forget I said anything. I mean, if really
necessary, you can just use Libera's server-password kludge while
testing (everything will still be encrypted):
(erc-tls :password "$myaccount:$mypass" ...)
> [...]
> (setq erc-autojoin-channels-alist

Ah, looks like we're missing
(setq erc-join-buffer 'frame
erc-auto-query 'frame
erc-reuse-frames 'displayed)
Also, you *did* apply the patch and rerun make (or at least delete the
.elc), right?:
https://lists.gnu.org/archive/html/emacs-erc/2022-08/txtAqY2ukHPun.txt
(Yeah, those changes aren't on trunk.) Anyway, please let me know if
something doesn't add up.
Thanks,
J.P.
P.S. If you want, you can use the symbol `Libera.Chat' instead of the

Indeed. And the "join" part makes it sound like it's only supposed to
affect channels. Therefore, I think this should be aliased to something
like `erc-buffer-display' because it also determines how server buffers
are shown. Doing so would maybe also aid in discoverability by bringing
it more in line with `erc-query-display' and `erc-reconnect-display'.
The same goes for `erc-auto-query', which could likewise become
`erc-receive-query-display' or similar.
We should also probably mention somewhere that the new default value of
`bury' doesn't put existing buffers at the end of the buffer list.
Moreover, I'm thinking that having `bury' as the default for interactive
invocations (which is now the case) may be too stark a proposition since
the only visual feedback afforded new users is a blip in the mode line.
(FWIW, one user on Libera has recently complained about this, going so
far as to label it a bug.) Anyway, the "penultimate" patch in the POC
portion of the set proposed in bug#60428 [1] incorporates some of these
ideas. If anyone's interested, please check it out. Thanks.

I've added a version of the frames patch as well as an option to control
buffer-display behavior for interactive entry-point invocations.

Just a breadcrumb for posterity: I've opened a related bug that picks up
where this one left off:
