uvgTorrent -c

Messing around with the torrent protocol. Very much a work in progress. The goal is to start by implementing the UDP tracker protocol, Peer Wire protocol and finally DHT based trackerless torrent support.

The main thread maintains state while trackers and peers running via a thread pool will check torrent state via a mutex protected interface and return completed units of work to the main thread via queues.

A Dockerfile is provided as I haven't gotten around to making this portable yet.

For details on the implementation see the comment at the top main.c, and the files noted there.

Quick usage

make clean all # clean & build
make clean all tests # clean & built & unit test
make clean all valgrind # clean & build & run under valgrind (public domain torrent)

to run the binary (this is a public domain example):

./bin/uvgTorrent --magnet_uri="magnet:?xt=urn:btih:08ada5a7a6183aae1e09d831df6748d566095a10&dn=Sintel&tr=udp%3A%2F%2Fexplodie.org%3A6969&tr=udp%3A%2F%2Ftracker.coppersurfer.tk%3A6969&tr=udp%3A%2F%2Ftracker.empire-js.us%3A1337&tr=udp%3A%2F%2Ftracker.leechers-paradise.org%3A6969&tr=udp%3A%2F%2Ftracker.opentrackr.org%3A1337" --path="/tmp"

if you give uvgTorrent non udp trackers at the moment you'll get weird errors due to sloppy input handling.

Docker Usage

If you aren't on x86 linux you can use docker to build test and run the client

docker build -t uvgtorrent .
mkdir download
docker run -v $(pwd)/download:/app/download --rm -ti uvgtorrent:latest

Dependencies

Linux OS
cmocka
libcurl
valgrind
GCC
gcovr
lcov & gcov

Testing

Tests can be found in the test directory. after running tests you can view a coverage report by running gcovr -v -r . or viewing the html report in coverage/html

I've set aside the testing for now and will revisit it once the main functionality is completed.
