atomgen ======== Infinite Atom Entries Generator Overview --------- The application providing two feeds. First one generating Atom entries every minute and the second one - every 5 minutes. The feeds can be used mostly for testing webhooks, pubsubhubbub etc. The one minute feed is protected by a secret token in the end of the URL. If your application is installed for example on URL http://example.com/ , the two feeds will be: http://example.com/feed/1/YouSecretHere (1min feed) http://example.com/feed/5 (5min feed) Usage ------ The application is currently deployed on Google AppEngine. You can use the 5 minutes feed for your tests - go to http://pubsubhubbub.appspot.com/subscribe and subscribe for the http://atomgen.appspot.com/feed/5 topic. This will send to your subscribers a new Atom entry every 5 minutes. There is also a FriendFeed group - http://friendfeed.com/atomgen , which is already subscribed to the 5 minutes feed. You can use it to gen notifications via IM etc. Implementation details ----------------------- The feeds have atom:link[@rel="hub"] element and the 5 minutes feed is pinging the hub on feed generation. By default the Google's reference implementation on URL http://pubsubhubbub.appspot.com/ is used. Your can change the hub with the HUB_URL option in the settings.py file. I tried to make the atom generator a good Internet cityzen by setting up the proper HTTP headers ('Last-Modified', 'ETag' etc.). 'Etag' header contains the ID of the last entry, cryptography signed, like suggested in http://code.google.com/p/pubsubhubbub/wiki/PublisherEfficiency The current implementation does not use Google Datastore. Feeds are kept only in the memcached object caching system. TODO ----- - Return only new entries for clients asking with 'If-None-Match' header (ETag)
