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.

Mentions

Downstream projects

There are several web-frontends, sites, Android clients, storage backends and supporting services among the known public projects:

  • cove: Personal torrent browser with streaming, DHT search, video transcoding and casting.
  • confluence: torrent client as a HTTP service
  • Gopeed: Gopeed (full name Go Speed), a high-speed downloader developed by Golang + Flutter, supports (HTTP, BitTorrent, Magnet) protocol, and supports all platforms.

Help

Communication about the project is primarily through Discussions and the issue tracker.

Command packages

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

torrent

torrent download

Downloads torrents from the command-line.

$ torrent download 'magnet:?xt=urn:btih:KRWPCX3SJUM4IMM4YF5RPHL6ANPYTQPU'
... lots of jibber jabber ...

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 &
$ cd torrents
$ wget http://releases.ubuntu.com/14.04.2/ubuntu-14.04.2-desktop-amd64.iso.torrent
