source: protocols/bee_chat.c @ 1fa5109

Last change on this file since 1fa5109 was be1efa3, checked in by dequis <dx@…>, at 2015-01-26T02:43:34Z

Add handle_is_self() prpl function to fix JID mismatch confusion bugs

When bee_chat needs to check for self messages, it can call this
function to let the protocol implementation do the comparison.

In the case of jabber, sometimes the server reports a different username
after login, this one is stored in jd->internal_jid, and the one that is
used for login isn't changed
