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.

summary: Subscribe to Atom and RSS feeds over pubsub

# Introduction

This module allows Prosody to fetch Atom and RSS feeds for you, and push
new results to subscribers over XMPP.

# Configuration

This module needs to be be loaded together with
[mod\_pubsub][doc:modules:mod\_pubsub].

For example, this is how you could add it to an existing pubsub
component:

``` lua
Component "pubsub.example.com" "pubsub"
modules_enabled = { "pubsub_feeds" }

feeds = {
  -- The part before = is used as PubSub node
  planet_jabber = "http://planet.jabber.org/atom.xml";
  prosody_blog = "http://blog.prosody.im/feed/atom.xml";
}
```

This example creates two nodes, 'planet\_jabber' and 'prosody\_blog'
that clients can subscribe to using
[XEP-0060](http://xmpp.org/extensions/xep-0060.html). Results are in
[ATOM 1.0 format](http://atomenabled.org/) for easy consumption.

# PubSubHubbub

This module also implements a
[PubSubHubbub](http://pubsubhubbub.googlecode.com/svn/trunk/pubsubhubbub-core-0.3.html)
subscriber. This allows feeds that have an associated "hub" to push
updates when they are published.

Not all feeds support this.

It needs to expose a HTTP callback endpoint to work.

# Option summary
