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)
