Jabber in Twisted

[Rico Huijbers]

Does anybody have experience in writing Jabber clients with Twisted? I
came across a simple sample[0], and tried to build out from it, but for
some reason it's barely working.

When I run the application in the attached script, the logon goes fine,
and I can receive messages sent to the account, but it never seems to
receive subscription requests. When I ran it on an account that already
had some items on the contact list, I did receive <presence> messages to
indcate that a user changed status, but I don't receive <presence
type="subscribe"> messages...

Ultimately, I tacked a "/*" handler on to the code to see if I was
receiving any packets at all, but the only thing that seems to trigger
anything are messages.

This is very frustrating for me. Is it a problem with the code, or am I
missing something in the Jabber protocol?

Any help would be greatly appreciated.

P.S: Please don't mind the code, I know it's a bit (a lot) hackish right
now, but my first step is to get it running. I'll make it beautiful
afterwards .

I think you'll get far more attention from the right people if
you subscribe to the twisted mailing list, and post your
inquiry there.

As with Zope, and some other large, non-standard packages, the dedicated
Twisted mailing list is where the core folks hang out. Some show up
here from time to time and answer questions, but you're doing yourself
a disservice by limiting the input to this general newsgroup/mailing
list.

Yes, I saw that, but since I find it easier to post to and read
newsgroups, and I already saw a couple of Twisted-related threads in
here, I figured I'd try here first.

But I'll take your suggestion and try again on the Twisted mailing list.

Thanks for your reply.
