Isohunt urls not loading

[Calum]

Every other torrent url I've tested works fine but Isohunt ones just don't load.

An example link and the error: ​http://ca.isohunt.com/download/44648933/big+buck+bunny.torrent

same problem using the gtkUI

[al.cadd9]

This issue could be resolved using GIO as a fallback. This patch ​http://dev.deluge-torrent.org/attachment/ticket/1549/deluge-console-add-gio.patch shows a real-world implementation for the console, while this simple script ​http://pastebin.com/insXbGgN could be used for testing. (thanks mathbr)

[Calum]

The failure in gtkui for isohunt urls is only when manually adding to 'add url' dialog box. Torrent files and urls clicked in the browser load fine.

For the webui all forms of attempting to add an isohunt torrent fail.

[John Garland]

This is due to isohunt returning an incorrect content-length header for compressed files (it sends the original size rather than the compressed size), confusing twisted (which httpdownloader uses) into thinking the connection was closed prematurely.

Isohunt should really fix this issue (there are reports on this from 2005!) however I will commit a fix to handle this in the meantime.

[John Garland]

This has been fixed in ​git and will be in the next release.
