mod_muc_rtbl: also filter messages
This was a bit tricky because we don't want to run the JIDs
through SHA256 on each message. Took a while to come up with this
simple plan of just caching the SHA256 of the JIDs on the
occupants.
This will leave some dirt in the occupants after unloading the
module, but that should be ok; once they cycle the room, the
hashes will be gone.
This is direly needed, otherwise, there is a tight race between
the moderation activities and the actors joining the room.

--- labels: - 'Stage-Beta' summary: Limit presence stanzas to save traffic ... Introduction ============ For most people 'presence' (status changes) of contacts make up most of the traffic received by their client. However much of the time it is not essential to have highly accurate presence information. This module automatically cuts down on presence traffic when clients indicate they are inactive (using the [CSI protocol](mod_csi.html)). This is extremely valuable for mobile clients that wish to save battery power while in the background. Configuration ============= Just load the module (e.g. in modules\_enabled). There are no configuration options. Compatibility ============= ----- ------- 0.9 Works ----- -------
