pybtracker

pybtracker is a UDP BitTorrent tracker written in Python 3.5 using co-routines and the asyncio module. You can use the tracker in a script like this:

from pybtracker import TrackerServer

loop = asyncio.get_event_loop()
tracker = TrackerServer(local_addr=('127.0.0.1', 8000), loop=loop)
asyncio.ensure_future(tracker.start())
try:
    loop.run_forever()
except KeyboardInterrupt:
    loop.run_until_complete(tracker.stop())

It also includes a UDP tracker client:

from pybtracker import TrackerClient

async def announce():
    client = TrackerServer(local_addr='udp://127.0.0.1:8000', loop=loop)
    await client.start()
    peers = await client.announce(
        b'01234567890123456789',  # infohash
        10000,                    # downloaded
        40000,                    # left
        5000,                     # uploaded
        0,                        # event (0=none)
        120                       # number of peers wanted
    )
    print(peers)

loop = asyncio.get_event_loop()
loop.run_until_complete(announce())

You can run the server independently by running:

$ python -m pybtracker.server -b 127.0.0.1:8000 -O

The client can also be run independently and it provides you with a shell to interact with the server:

$ python -m pybtracker.client udp://127.0.0.1:8000
BitTorrent tracker client. Type help or ? to list commands.

If you have installed pybtracker using pip or setup.py, you can also run pybtracker and pybtracker-client instead of using python -m.
