# Configuration
|
||||
|
||||
Chihaya's behaviour is customized by setting up a JSON configuration file.
|
||||
Available keys are as follows:
|
||||
|
||||
##### `httpListenAddr`
|
||||
|
||||
type: string
|
||||
default: "localhost:6881"
|
||||
|
||||
The listen address for the HTTP server. If only a port is specified, the tracker will listen on all interfaces. If left empty, the tracker will not run a HTTP endpoint.
|
||||
|
||||
##### `httpRequestTimeout`
|
||||
|
||||
type: duration
|
||||
default: "4s"
|
||||
|
||||
The duration to allow outstanding requests to survive before forcefully terminating them.
|
||||
|
||||
##### `httpReadTimeout`
|
||||
|
||||
type: duration
|
||||
default: "4s"
|
||||
|
||||
The maximum duration before timing out read of the request.
|
||||
|
||||
##### `httpWriteTimeout`
|
||||
|
||||
type: duration
|
||||
default: "4s"
|
||||
|
||||
The maximum duration before timing out write of the request.
|
||||
|
||||
##### `httpListenLimit`
|
||||
|
||||
type: integer
|
||||
default: 0
|
||||
|
||||
Limits the number of outstanding requests. Set to `0` to disable.
|
||||
|
||||
##### `udpListenAddr`
|
||||
|
||||
type: string
|
||||
default: "localhost:6881"
|
||||
|
||||
Then listen address for the UDP server. If only a port is specified, the tracker will listen on all interfaces. If left empty, the tracker will not run a UDP endpoint.
|
||||
|
||||
##### `createOnAnnounce`
|
||||
|
||||
type: bool
|
||||
default: true
|
||||
|
||||
Whether to register new torrents with the tracker when any client announces (`true`), or to return an error if the torrent doesn't exist (`false`).
|
||||
|
||||
##### `purgeInactiveTorrents`
|
||||
|
||||
type: bool
|
||||
default: true
|
||||
|
||||
If torrents should be forgotten when there are no active peers.
|
||||
|
||||
##### `announce`
|
||||
|
||||
type: duration
|
||||
default: "30m"
|
||||
|
||||
The announce `interval` value sent to clients. This specifies how long clients should wait between regular announces.
|
||||
|
||||
##### `minAnnounce`
|
||||
|
||||
type: duration
|
||||
default: "30m"
|
||||
|
||||
The announce `min_interval` value sent to clients. This theoretically specifies the minimum allowed time between announces, but most clients don't really respect it.
|
||||
|
||||
##### `defaultNumWant`
|
||||
|
||||
type: integer
|
||||
default: 50
|
||||
|
||||
The default maximum number of peers to return if the client has not requested a specific number.
|
||||
|
||||
##### `allowIPSpoofing`
|
||||
|
||||
type: bool
|
||||
default: true
|
||||
|
||||
Whether peers are allowed to set their own IP via the various supported methods or if these are ignored. This must be enabled for dual-stack IP support, since there is no other way to determine both IPs of a peer otherwise.
|
||||
|
||||
##### `dualStackedPeers`
|
||||
|
||||
type: bool
|
||||
default: true
|
||||
|
||||
True if peers may have both an IPv4 and IPv6 address, otherwise only one IP per peer will be used.
|
||||
|
||||
##### `realIPHeader`
|
||||
|
||||
type: string
|
||||
default: blank
|
||||
|
||||
An optional HTTP header indicating the upstream IP, for example `X-Forwarded-For` or `X-Real-IP`. Use this when running the tracker behind a reverse proxy.
|
||||
|
||||
##### `respectAF`
|
||||
|
||||
type: bool
|
||||
default: false
|
||||
|
||||
Whether responses should only include peers of the same address family as the announcing peer, or if peers of any family may be returned (i.e. both IPv4 and IPv6).
|
||||
|
||||
##### `clientWhitelistEnabled`
|
||||
|
||||
type: bool
|
||||
default: false
|
||||
|
||||
Enables the peer ID whitelist.
|
||||
|
||||
##### `clientWhitelist`
|
||||
|
||||
type: array of strings
|
||||
default: []
|
||||
|
||||
List of peer ID prefixes to allow if `client_whitelist_enabled` is set to true.
|
||||
|
||||
##### `torrentMapShards`
|
||||
|
||||
type: integer
|
||||
default: 1
|
||||
|
||||
Number of internal torrent maps to use. Leave this at 1 in general, however it can potentially improve performance when there are many unique torrents and few peers per torrent.
|
||||
|
||||
##### `reapInterval`
|
||||
|
||||
type: duration
|
||||
default: "60s"
|
||||
|
||||
Interval at which a search for inactive peers should be performed.
|
||||
|
||||
##### `reapRatio`
|
||||
|
||||
type: float64
|
||||
default: 1.25
|
||||
|
||||
Peers will be rated inactive if they haven't announced for `reapRatio * minAnnounce`.
|
||||
|
||||
##### `apiListenAddr`
|
||||
|
||||
type: string
|
||||
default: "localhost:6880"
|
||||
|
||||
The listen address for the HTTP API. If only a port is specified, the tracker will listen on all interfaces. If left empty, the tracker will not run the HTTP API.
|
||||
|
||||
##### `apiRequestTimeout`
|
||||
|
||||
type: duration
|
||||
default: "4s"
|
||||
|
||||
The duration to allow outstanding requests to survive before forcefully terminating them.
|
||||
|
||||
##### `apiReadTimeout`
|
||||
|
||||
type: duration
|
||||
default: "4s"
|
||||
|
||||
The maximum duration before timing out read of the request.
|
||||
|
||||
##### `apiWriteTimeout`
|
||||
|
||||
type: duration
|
||||
default: "4s"
|
||||
|
||||
The maximum duration before timing out write of the request.
|
||||
|
||||
##### `apiListenLimit`
|
||||
|
||||
type: integer
|
||||
default: 0
|
||||
|
||||
Limits the number of outstanding requests. Set to `0` to disable.
|
||||
|
||||
##### `driver`
|
||||
|
||||
type: string
|
||||
default: "noop"
|
||||
|
||||
Sets the backend driver to load. The included `"noop"` driver provides no functionality.
|
||||
|
||||
##### `statsBufferSize`
|
||||
|
||||
type: integer
|
||||
default: 0
|
||||
|
||||
The size of the event-queues for statistics.
|
||||
|
||||
##### `includeMemStats`
|
||||
|
||||
type: bool
|
||||
default: true
|
||||
|
||||
Whether to include information about memory in the statistics.
|
||||
|
||||
##### `verboseMemStats`
|
||||
|
||||
type: bool
|
||||
default: false
|
||||
|
||||
Whether the information about memory should be verbose.
|
||||
|
||||
##### `memStatsInterval`
|
||||
|

type: duration
|
||||
default: "5s"
|
||||
|
||||
Interval at which to collect statistics about memory.
|
||||
|
||||
|
||||
##### `jwkSetURI`
|
||||
|
||||
type: string
|
||||
default: ""
|
||||
|
||||
If this string is not empty, then the tracker will attempt to use JWTs to validate infohashes before announces. The format for the JSON at this endpoint can be found at [the RFC for JWKs](https://tools.ietf.org/html/draft-ietf-jose-json-web-key-41#page-10) with the addition of an "issuer" key. Simply stated, this feature requires two fields at this JSON endpoint: "keys" and "issuer". "keys" is a list of JWKs that can be used to validate JWTs and "issuer" should match the "iss" claim in the JWT. The lifetime of a JWK is based upon standard HTTP caching headers and falls back to 5 minutes if no cache headers are provided.
|
||||
|
||||
|
||||
#### `jwkSetUpdateInterval`
|
||||
|
||||
type: duration
|
||||
default: "5m"
|
||||
|
||||
The interval at which keys are updated from JWKSetURI. Because the fallback lifetime for keys without cache headers is 5 minutes, this value should never be below 5 minutes unless you know your jwkSetURI has caching headers.
|
||||
|
||||
#### `jwtAudience`
|
||||
|
||||
type: string
|
||||
default: ""
|
||||
|
||||
The audience claim that is used to validate JWTs.

## Communication
|
||||
|
||||
Currently, real time conversation happens on [#chihaya] on [freenode].
|
||||
We are currently attempting to have more information available on GitHub.

|
||||
## Pull request procedure
|
||||
|
||||
Please don't write massive patches without prior communication, as it will most
|
||||
likely lead to confusion and time wasted for everyone. However, small
|
||||
unannounced fixes are always welcome!
|
||||
|
||||
Pull requests will be treated as "review requests", and we will give
|
||||
feedback we expect to see corrected on [style] and substance before merging.
|
||||
Changes contributed via pull request should focus on a single issue at a time,
|
||||
like any other. We will not accept pull-requests that try to "sneak" unrelated
|
||||
changes in.
|
||||
|
||||
The average contribution flow is as follows:
|
||||
|
||||
- Create a topic branch from where you want to base your work. This is usually `master`.
|
||||
- Make commits of logical units.
|
||||
- Make sure your commit messages are in the [proper format]
|
||||
- Push your changes to a topic branch in your fork of the repository.
|
||||
- Submit a pull request.
|
||||
- Your PR will be reviewed and merged by one of the maintainers.
|
||||
|
||||
|
||||
Any new files should include the license header found at the top of every
|
||||
source file.

|
||||
|
||||
## Style
|
||||
|
||||
### Go
|
||||
|
||||
The project follows idiomatic [Go conventions] for style. If you're just
|
||||
starting out writing Go, you can check out this [meta-package] that documents
|
||||
style idiomatic style decisions you will find in open source Go code.
|
||||
|
||||
|
||||
[Go conventions]: https://github.com/golang/go/wiki/CodeReviewComments
|
||||
[meta-package]: https://github.com/jzelinskie/conventions
|
||||
|
||||
### Commit Messages
|
||||
|
||||
We follow a rough convention for commit messages that is designed to answer two
|
||||
questions: what changed and why. The subject line should feature the what and
|
||||
the body of the commit should describe the why.
|
||||
|
||||
```
|
||||
scripts: add the test-cluster command
|
||||
|
||||
this uses tmux to setup a test cluster that you can easily kill and
|
||||
start for debugging.
|
||||
|
||||
Fixes #38
|
||||
```
|
||||
|
||||
The format can be described more formally as follows:
|
||||
|
||||
```
|
||||
<subsystem>: <what changed>
|
||||
<BLANK LINE>
|
||||
<why this change was made>
|
||||
<BLANK LINE>
|
||||
<footer>
|
||||
```
|
||||
|
||||
The first line is the subject and should be no longer than 70 characters, the
|
||||
second line is always blank, and other lines should be wrapped at 80 characters.
|
||||
This allows the message to be easier to read on GitHub as well as in various
|
||||
git tools.

|

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).
|
||||
|
||||
Current features include:
|
||||
|
||||
- Public tracker feature-set with full compatibility with what exists of the BitTorrent spec
|
||||
- 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
|
||||
- JWT Validation to approve the usage of a given infohash.
|
||||
|
||||
Planned features include:
|
||||
|
||||
- Private tracker feature-set with compatibility for a [Gazelle]-like deployment (WIP)
|
||||

||||

|
||||

|
||||
|
||||
## 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.

## 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].
|
||||
|
||||
[`example_config.json`]: https://github.com/chihaya/chihaya/blob/master/example_config.json
|
||||
[CONFIGURATION.md]: https://github.com/chihaya/chihaya/blob/master/CONFIGURATION.md
|
||||
|
||||
### Docker
|
||||
|
||||
```sh
|
||||
$ docker pull quay.io/jzelinskie/chihaya:latest
|
||||
$ export CHIHAYA_LOG_LEVEL=5 # most verbose, and the default
|
||||
$ docker run -p 6880-6882:6880-6882 -v $PATH_TO_DIR_WITH_CONF_FILE:/config:ro -e quay.io/jzelinskie/chihaya:latest -v=$CHIHAYA_LOG_LEVEL
|
||||
```
|
||||
|
||||
## 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 .
|
||||
```
|
||||
|
||||
