Atrack - A Tracker for Google’s App Engine

Atrack is a ntrack / Bittorrent tracker designed from the ground up to run on Google’s App Engine grid.

Its main goals are:

For this it relies heavily (and almost completely) on memcached, no data is stored anywhere, and it lets memcached do most of the lifecycle management.

Atrack also aims to respect your privacy: other than what is needed for the most basic tracking (hashes/keys and ip/ports) atrack gathers no information whatsoever. Beyond that no aggregate statistics are kept of anything (at least once the testing/debugging phase is over), and nothing is stored permanently anywhere, not even hashes and ip/ports, they are kept in memory until they are expired by memcached and never written to disk or any other kind of permanent storage.

TODO

Future:

Source

The latest atrack source is kept in a Mercurial repository, you can check it out as follows:

hg clone http://hg.cat-v.org/atrack/

Contact

For feedback, bug reports, or anything else contact me. Or join #cat-v in irc.freenode.org.

Known Atrack Installations

There are many others, and none is warranted to work, installations come and go often.

You can look for more (working) installation at Trackon.

License

None. Atrack is in the public domain. Because intellectual property is an oxymoron. Alternatively, if the laws of your country are so braindamaged that they don’t recognize the public domain, the code is also available under the ISC and MIT/X licenses.
