# Chihaya [](https://travis-ci.org/chihaya/chihaya)
|
|
|
|
Chihaya is a high-performance [BitTorrent tracker](http://en.wikipedia.org/wiki/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.
|
|
|
|
Features include:
|
|
|
|
- Low resource consumption, and fast, asynchronous request processing
|
|
- Full IPv6 support, including handling for dual-stacked peers
|
|
- Generic storage interfaces that are easily adapted to work with any database
|
|
- Full compatibility with what exists of the BitTorrent spec
|
|
- Extensive metrics for visibility into the tracker and swarm's performance
|
|
- Ability to group peers in local subnets to reduce backbone contention
|
|
|
|
## Using Chihaya
|
|
|
|
Chihaya can be ran as a public or private tracker and is intended to work with existing torrent-indexing web frameworks, such as [Gazelle], [Batter] and any others that spring up. Following the Unix way, it is built to perform one specific task: handling announces and scrapes. By cleanly separating the concerns between tracker and database, we can provide an interface that can be used by system that needs its functionality. See [below](#drivers) for more info.

|
### Installing
|
|
|
|
Chihaya requires Go 1.3+ to build. To install the Chihaya server, run:
|
|
|
|
```sh
|
|
$ go get github.com/chihaya/chihaya/cmd/chihaya
|
|
```
|
|
|
|
Make sure you have your `$GOPATH` set up correctly, and have `$GOPATH/bin` in your `$PATH`.
|
|
If you're new to Go, an overview of the directory structure can be found [here](http://golang.org/doc/code.html).
|
|
|
|
### Configuring
|
|
|
|
Configuration is done in a JSON formatted file specified with the `-config`
|
|
flag. An example configuration file can be found
|
|
[here](https://github.com/chihaya/chihaya/blob/master/example.json).
|
|
|
|
### Running the tests
|
|
|
|
```sh
|
|
$ cd $GOPATH/src/github.com/chihaya/chihaya
|
|
$ go test -v ./...
|
|
```
|
|
|
|
### Technical Details
|
|
|
|
See [the wiki](https://github.com/chihaya/chihaya/wiki) for a discussion of the design behind Chihaya.
|
|
|
|
## Drivers
|
|
|
|
Chihaya is designed to remain agnostic about the choice of data store for an
|
|
application, and it is straightforward to [implement a new driver]. However, there
|
|
are a number of drivers that will be directly supported "out of the box":
|
|
|
|
Tracker:
|
|
|
|
* memory
|
|
* [redis](https://github.com/chihaya/chihaya-redis)
|
|
|
|
Backend:
|
|
|
|
* noop (for public trackers)
|
|
* [gazelle (mysql)](https://github.com/chihaya/chihaya-gazelle)
|
|
|
|
To use an external driver, make your own package and call it something like `github.com/yourusername/chihaya`. Then, import Chihaya like so:
|
|
|
|
```go
|
|
package main
|
|
|
|
import (
|
|
"github.com/chihaya/chihaya"
|
|
|
|
_ "github.com/yourusername/chihaya-custom-backend" // Import any of your own drivers.
|
|
)
|
|
|
|
func main() {
|
|
chihaya.Boot() // Start Chihaya normally.
|
|
}
|
|
```
|
|
|
|
Then, when you do `go install github.com/yourusername/chihaya`, your own drivers will be included in the binary.

massive patches with no prior communication, as it will most
