after-cloak channel join fails on freenode

[ghost]

I've got following configuration (init.el) in GNU Emacs 25.3.2 (x86_64-pc-linux-gnu, GTK+ Version 3.22.11) with Circe version 2.6 (installed via package.el):
'(circe-network-options (quote (("Freenode" :sasl-password mypassword :sasl-username myname :channels (:after-cloak "#freenode" "#emacs-circe") :nickserv-password mypassword :use-tls t :port 6697)))) '(circe-server-auto-join-default-type :after-cloak)
The authentication works as expected, the cloak (@unaffiliated/myname) is applied properly (checked via nickserv status) but no channels are joined. If I join them manually it works fine.

Would be nice to get autojoin working as advertised.

Note: if you need cloak for testing, just request it directly from any stuff member on freenode - you can see currently available staff via /quote stats p command. Ask nicely via PM and you'll get one.

Thank you for the report! Could you do M-: (setq irc-debug-log t) and see if cloaking sends a 396 response (that's RPL_HOSTHIDDEN)? If not, what's the server message to notify you of a cloak being applied?

[ghost]

Sure, where can I find the debug log?

[jorgenschaefer]

It's in a buffer called *IRC Protocol ...* :-)

Indeed, no such message at all, below is my log sample.

Could it be due to use of SASL auth?

[jorgenschaefer]

I think when you use SASL, Freenode automatically applies cloaking without any particular handshake, so Circe does not know it's cloaking. You can use the after-auth hook then.

Cool, I think it's worth it to document this on a wiki: the event name, enabling debug log, recommended setting for sasl auth etc.

[jorgenschaefer]

Sounds like an idea. It's always a bit tricky on whether to document idiosyncrasies of a single IRC network with a generic IRC client, but considering Freenode is like 90% of IRC these days, I guess that makes sense. :-)
