Hello, I am happy to announce HaskellTorrent v0.0, a concurrent bittorrent client. The current release is a rather early preview release: it can download torrents and seed them, but currently there are many optimizations and tweaks needed before it is ready for day-to-day use. In particular, we are not yet fully compliant with the bittorrent specification and need proper clients to connect to in order to operate. Basically, you install the cabal package and then run HaskellTorrent foo.torrent and it will then download the contents of the torrent to the current directory. We would like to hear about any kind of problems you might encounter. Send them to jesper.louis.andersen@gmail.com for now. We have only tested the software on GHC 6.10.4 and 6.12.1, mostly on Unix platforms. It is known to work on Debian/Unstable with GHC610 and GHC612. If you want to hack code, get in touch with me. There are something for any level of skill to do. *** HaskellTorrent is using the CML library to get concurrency. It easily runs some 200-300 processes when it operates and its process model is somewhat loosely inspired by the model of Erlang. Looking forward, the next goal is to optimize concurrency, memory usage and CPU usage in the client. It currently hogs resources due to naive data structure choices and some expensive correctness assertions. *** Links of interest: http://hackage.haskell.org/package/HaskellTorrent http://github.com/jlouis/haskell-torrent *** This release was brought to you by: Alex Mason: A lot of Wireprotocol and BCode serialization work through the use of the cereal package.
