seanoflynn / research-bittorrent Goto Github PK

Hello Sean,
I very like your bittorent project and was follow it about week or two, but suddenly the tutorial is offline( http://seanjoflynn.com/research/bittorrent ). I was using your research very hard so if you closed the page permanently could you be so kind to send me content of this page( http://seanjoflynn.com/research/bittorrent ) or what you still have. I was stupid to not back up your page at first place.
Thank you very much
Sincerely yours, Alex O

I'm really interested by the work you did here and I would like to know if you are still working on this or not.

Please contact me by email (Github profile) if you read this.

Do you intend to continue your development of this to include DHT/Peer Exchange. The work you have done here has help me a lot in understanding BitTorrent in C#!

The full writeup was really good, but the link is broken ( seanjoflynn.com/research/bittorrent ). Would be good to keep that around, maybe in this repo even.

There's a typecasting issue in Bittorrent/Torrent.cs on line 270:
return Read(piece * PieceSize, GetPieceSize(piece));

If piece * PieceSize > Int32.MaxValue then it will overflow to a negative Int32 value before being cast to Int64. Implicit cast so torrents with a total file size > 2GB can be downloaded/verified. Like so:

return Read((long)piece * (long)PieceSize, GetPieceSize(piece));

Could you add a license file?

This project seems really interesting. I found a lot of praise for it on hackernews, and it's something I've been willing to learn for a long time. Any chance you've still got the text?
