|
Chihaya is a high-performance [BitTorrent tracker] written in the Go
|
|
programming language. It is still heavily under development and the current
|
|
`master` branch should probably not be used in production
|
|
(unless you know what you're doing).
|
|
|
|
Features include:
|
|
|
|
- Public tracker feature-set with full compatibility with what exists of the BitTorrent spec
|
|
- Private tracker feature-set with compatibility for a [Gazelle]-like deployment (WIP)
|
|
- Low resource consumption, and fast, asynchronous request processing
|
|
- Full IPv6 support, including handling for dual-stacked peers
|
|
- Extensive metrics for visibility into the tracker and swarm's performance
|
|
- Ability to prioritize peers in local subnets to reduce backbone contention
|
|
- Pluggable backend driver that can coordinate with an external database

## When would I use Chihaya?
|
|
|
|
Chihaya is a eventually meant for every kind of BitTorrent tracker deployment.
|
|
Chihaya has been used to replace instances of [opentracker] and also instances of [ocelot].
|
|
Chihaya handles torrent announces and scrapes in memory.
|
|
However, using a backend driver, Chihaya can also asynchronously provide deltas to maintain a set of persistent data without throttling a database.
|
|
This is particularly useful behavior for private tracker use-cases.

## Running Chihaya
|
|
|
|
### Configuration
|
|
|
|
Copy [`example_config.json`] to your choice of location, and update the values as required.
|
|
An explanation of the available keys can be found in [CONFIGURATION.md].

|
|
|
|
### Docker
|
|
|
|
```sh
|
|
$ docker pull quay.io/jzelinskie/chihaya:latest
|
|
$ docker run -p 6881:6881 -v $DIR_WITH_CONFIG:/config:ro quay.io/jzelinskie/chihaya:latest
|
|
```

## Developing Chihaya
|
|
|
|
### Building & Installing
|
|
|
|
Chihaya requires Go 1.5+ (preferrably the latest stable Go), [Godep], and a [Go environment] previously set up.
|
|
|
|
[Godep]: https://github.com/tools/godep
|
|
[Go environment]: https://golang.org/doc/code.html
|
|
|
|
```sh
|
|
$ export GOPATH=$PWD/chihaya
|
|
$ git clone https://github.com/chihaya/chihaya.git chihaya/src/github.com/chihaya/chihaya
|
|
$ cd chihaya/src/github.com/chihaya/chihaya/cmd/chihaya/
|
|
$ godep restore
|
|
$ go install github.com/chihaya/chihaya/cmd/chihaya
|
|
```
|
|
|
|
### Testing
|
|
|
|
Chihaya has end-to-end test coverage for announces in addition to unit tests for isolated components.
|
|
To run the tests, use:
|
|
|
|
```sh
|
|
$ cd $GOPATH/src/github.com/chihaya/chihaya
|
|
$ godep go test -v ./...
|
|
```
|
|
|
|
There is also a set of benchmarks for performance-critical sections of Chihaya.
|
|
These can be run similarly:
|
|
|
|
```sh
|
|
$ cd $GOPATH/src/github.com/chihaya/chihaya
|
|
$ godep go test -v ./... -bench .
|
|
```
|
|
