Chihaya

Chihaya is a high-performance BitTorrent tracker written in the Go programming language. It isn't quite ready for prime-time just yet, but these are the features it targets:

• Low resource consumption
• Fast request processing
• A generic storage interface that is easily adapted to use any data store
• Scaling properties that directly correlate with those of the chosen data store
• Correct IPv6 support
• Maximum compatibility with what exists of the BitTorrent spec

Installing

First, you'll need to install libzmq with your favourite package manager. Then,

$ go install github.com/pushrax/chihaya

Configuring

Configuration is done in a JSON formatted file specified with the -config flag. An example configuration can be seen in the exampleConfig variable of config/config_test.go.

Default storage drivers

Chihaya currently supports the following drivers out of the box:

• redis

Custom storage drivers

The storage package is heavily inspired by the standard library's database/sql package. To write a new storage backend, create a new Go package that has an implementation of the DS, Tx, and Driver interfaces. Within that package, you must also define an init() that calls storage.Register.

Please read the documentation and understand these interfaces as there are assumptions made about thread-safety. After you've implemented a new driver, all you have to do is remember to add import _ path/to/your/library to the top of any file (preferably main.go) and the side effects from func init() will globally register your driver so that config files will recognize your driver by name. If you're writing a driver for a popular data store, consider contributing it.

Contributing

If you're interested in contributing, please contact us in #chihaya on freenode (webchat) or post to the issue tracker. Please don't offer massive pull requests with no prior communication attempts as it will most likely lead to confusion and time wasted for everyone. However, small unannounced fixes are always welcome.

And remember: good gophers always use gofmt!
