Pidgin freezes frequently with purple-facebook.

[AJolly]

Pidgin freezes frequently with the facebook plugin for me: Clicking into a chat window, or typing will freeze and block input for a few seconds.

I'm running this on a powerful machine, but suspect it might have to do with the large number of facebook friends I have?

the large number of facebook friends I have?

What number?

[AJolly]

3600 friends, 2400 followers. I tried turning off the buddy icons in case loading those resources was where the freezes were coming from.

Really not sure why I keep getting these freezes. It does seem like whatever thread is active is synchronous and blocks input. I've got this on two different computers. Any advice on how to best diagnose?

[dequis]

May help to get me a full debug log https://github.com/dequis/purple-facebook/wiki/Debugging-Logs - but my hopes of getting something useful out of it aren't high, to be honest.

I've also noticed slowdown of Pidgin with this addon (~700 contacts), but I don't know if it's just Pidgin behavior (I don't have any other accounts with comparable contacts number), or something 'purple-facebook' specific. That's sounds moar like work for code profiler, not debugger...

Thanks! I'm more of a security guy than a dev, but I'll take a look at that/and sniff the network traffic and see if I can get any insight.

The log seems to support my theory that it has to do with the large number of fb friends. Whenever I see it freeze (so far), the log is writing 500+ lines of "(17:57:52) blist: Updating buddy status for 645397917 (Facebook)" for various FB friends.

The other time I notice an issue:

Pidgin will freeze/blocking input, and the log file will pause at that exact point for upwards of 30 seconds, before resuming.

Also seems that on one computer I end up getting "facebook: Attempting to reconnect the MQTT stream..." frequently. When it does reconnect, it then resynchronizes what looks like the full buddy status list, causing the freeze. (Interestingly, on my other computer, even on the same wired network, run side by side, that one rarely has the MQTT stream error)
