Hi Brett!

After our upgrade to ngIRCd 20.1, users using Colloquy 2.3 basically cannot use server-local &channels. The client renders any public messages sent to those channels as private messages from the sender. In other words, messages that should show up in the &channel pane end up in a private query pane instead.

We haven't received any similar reports from other clients, and even Colloquy 2.4 is reported to work correctly, so this seems like a client-specific bug. But this all worked fine in ngIRCd 19.2, so I'm wondering if anyone has any ideas about what might have changed server-side that could trigger this?

So this is quite interesting, and as you already guessed, it's indeed a client bug. And sadly one we can't work around:

Colloquy <2.4 seems to have a broken ISUPPORT(005) numeric parser: the only(!) difference that matters concerning this bug is the different value of the "PREFIX" variable in this numeric:

v19.x: :irc.test.net 005 nick PREFIX=(ov)@+ v20.x: :irc.test.net 005 nick PREFIX=(qaohv)~&@%+

As soon as PREFIX lists the channel mode character "&", Colloquoy fails in becoming the target of "PRIVMSG &channel :text" commands right.

Colloquy 2.4[.1] have been fixed obviously, probably this is related to the following bug report: http://colloquy.info/project/ticket/2291 -- but I didn't look closer, so this is a wild guess only ...

In the end, I don't see much we can do about this: the ISUPPORT(005) numeric that ngIRCd 20.x sends is correct, and the old Colloquoy fails. Hm.
