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-Alpha' summary: 'XEP-0273: Stanza Interception and Filtering Technology' ... Introduction ============ [SIFT][XEP-0273] is a technology to allow clients to filter incoming traffic on the server. This helps save bandwidth, etc. Compatibility ============= ----- ------- 0.7 Works ----- ------- Quirks ====== This implementation is a work in progress. - Stanzas to full JIDs get sifted correctly - Stanzas to bare JIDs are currently allowed/disallowed for all resources as a whole, and not for individual resources - Presence is only sent to available resources, and probes are not sent for unavailable reasources - This module currently does not interact with offline messages (filtered messages are dropped with an error reply) - Not tested with privacy lists
