torrent

PkgGoDev

This repository implements BitTorrent-related packages and command-line utilities in Go. The emphasis is on use as a library from other projects. It's been used 24/7 in production by downstream services since late 2014. The implementation was specifically created to explore Go's concurrency capabilities, and to include the ability to stream data directly from the BitTorrent network. To this end it supports seeking, readaheads and other features exposing torrents and their files with the various Go idiomatic io package interfaces. This is also demonstrated through torrentfs.

There is support for protocol encryption, DHT, PEX, uTP, and various extensions. There are several data storage backends provided: blob, file, bolt, mmap, and sqlite, to name a few. You can write your own to store data for example on S3, or in a database.

Some noteworthy package dependencies that can be used for other purposes include:

Installation

Install the library package with go get github.com/anacrolix/torrent, or the provided cmds with go install github.com/anacrolix/torrent/cmd/...@latest.

Library examples

There are some small examples in the package documentation.

Command packages

Here I'll describe what some of the packages in ./cmd do. See installation to make them available.

torrent

torrent metainfo magnet

Creates a magnet link from a torrent file. Note the extracted trackers, display name, and info hash.

$ torrent metainfo testdata/debian-10.8.0-amd64-netinst.iso.torrent magnet
magnet:?xt=urn:btih:4090c3c2a394a49974dfbbf2ce7ad0db3cdeddd7&dn=debian-10.8.0-amd64-netinst.iso&tr=http%3A%2F%2Fbttracker.debian.org%3A6969%2Fannounce

See torrent metainfo --help for other metainfo related commands.

torrentfs

torrentfs mounts a FUSE filesystem at -mountDir. The contents are the torrents described by the torrent files and magnet links at -metainfoDir. Data for read requests is fetched only as required from the torrent network, and stored at -downloadDir.

$ mkdir mnt torrents
$ torrentfs -mountDir=mnt -metainfoDir=torrents &

Documentation

Overview

Package torrent implements a torrent client. Goals include:

  • Configurable data storage, such as file, mmap, and piece-based.
  • Downloading on demand: torrent.Reader will request only the data required to satisfy Reads, which is ideal for streaming and torrentfs.

BitTorrent features implemented include:

  • Protocol obfuscation
  • DHT
  • uTP
  • PEX
  • Magnet links
  • IP Blocklists
  • Some IPv6
  • HTTP and UDP tracker clients
  • BEPs:
  • 3: Basic BitTorrent protocol
  • 5: DHT
  • 6: Fast Extension (have all/none only)
  • 7: IPv6 Tracker Extension
  • 9: ut_metadata
  • 10: Extension protocol
  • 11: PEX
  • 12: Multitracker metadata extension
  • 15: UDP Tracker Protocol
  • 20: Peer ID convention ("-GTnnnn-")
  • 23: Tracker Returns Compact Peer Lists
  • 29: uTorrent transport protocol
  • 41: UDP Tracker Protocol Extensions
  • 42: DHT Security extension
  • 43: Read-only DHT Nodes
Example 
package main

import (
	"log"

	"github.com/anacrolix/torrent"
)

func main() {
	c, _ := torrent.NewClient(nil)
	defer c.Close()
	t, _ := c.AddMagnet("magnet:?xt=urn:btih:ZOCMZQIPFFW7OLLMIC5HUB6BPCSDEOQU")
	<-t.GotInfo()
	t.DownloadAll()
	c.WaitAll()
	log.Print("ermahgerd, torrent downloaded")
}

Output:
Example (FileReader) 
package main

import (
	"github.com/anacrolix/torrent"
)

func main() {
	var f torrent.File
	// Accesses the parts of the torrent pertaining to f. Data will be
	// downloaded as required, per the configuration of the torrent.Reader.
	r := f.NewReader()
	defer r.Close()
}

var (

	// This could move at any time. It contains counts of chunks received and the conditions they

	ChunksReceived expvar.Map

I could move a lot of these counters to their own file, but I suspect they may be attached to a Client someday.

type ConnStats

	ChunksReadUseful Count
	ChunksReadWasted Count

	MetadataChunksRead Count

	// Number of pieces data was written to, that subsequently passed verification.
	PiecesDirtiedGood Count
	// Number of pieces data was written to, that subsequently failed verification. Note that a
	// connection may not have been the sole dirtier of a piece.
	PiecesDirtiedBad Count
}

Various connection-level metrics. At the Torrent level these are aggregates. Chunks are messages with data payloads. Data is actual torrent content without any overhead. Useful is something we needed locally. Unwanted is something we didn't ask for (but may still be useful). Written is things sent to the peer, and Read is stuff received from them. Due to the implementation of Count, must be aligned on some platforms: See https://github.com/anacrolix/torrent/issues/262.
