mod_pubsub_feeds: Track latest timestamp seen in feeds instead of last poll This should ensure that an entry that has a publish timestmap after the previously oldest post, but before the time of the last poll check, is published to the node. Previously if an entry would be skipped if it was published at 13:00 with a timestamp of 12:30, where the last poll was at 12:45. For feeds that lack a timestamp, it now looks for the first post that is not published, assuming that the feed is in reverse chronological order, then iterates back up from there.

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.

# WebSub {#pubsubhubbub}

This module also implements [WebSub](https://www.w3.org/TR/websub/),
formerly known as
[PubSubHubbub](http://pubsubhubbub.googlecode.com/svn/trunk/pubsubhubbub-core-0.3.html).
This allows "feed hubs" to instantly push feed updates to subscribers.

This may be removed in the future since it does not seem to be oft used
anymore.
