Design - HenryHu/pybbs Wiki
Currently, the system is multi-threaded. Since there is no synchronization, there are many problems here.
notify error: unsupported-stanza-type "presence"
Notify thread accessed a ServerCore which has not been initialized.
roster.updater exception: dictionary changed size during iteration
Updater thread was iterating on the rosters._rosters, while a user logged in/logged out, changes rosters._rosters
Either: 1. Add synchronization 2. Restore single-threaded design
Allow delegated method execution: still requires synchronization Remove other threads: how to inject timeout events?
Unrecognized Stanza "presence" in xmppstream.py:start()
Reason unknown. "presence" tag in wrong order?
