Acme IRC Basic SASL Support

[Connor Taffe]

Good evening,

I’ve taken the client at https://swtch.com/irc/ and added enough SASL PLAIN support to access Freenode so that I could use it as my IRC client.

It’s available at https://github.com/cptaffe/airc.

I documented the flow as best I could in this commit , and I’d appreciate constructive feedback on how to improve the implementation or add more comprehensive SASL support. My initial idea was to support CertFP, but I had difficulty getting tlsClient in libsec to work, and reading through the code I’m not sure it supports sending the client certificate (there’s a bit which indicates it always sends an empty cert).

Another peculiarity is that mk all fails with a symbol error because it builds Irc.o and irc.o from irc.c on macOS, I believe this is to do with case-insensitivity in Apple’s FS. To get around this, just run the 9l command by hand without Irc.o.

After mk install, running "Irc -n nick -p passed irc.freenode.net" should attempt SASL PLAIN.

Speaking of IRC, is there a plan9port IRC channel?

Best,

Connor

That is terrific. I've been wanting to find a basic irc client with
SASL support for a long while now. Have been trying out several IRC
clients and wasn't thrilled with any of them. Really appreciate that
you did this.

Sincerely,
Laura
