Deluge misbehaving with a particular torrent

[r1348]

Hello, I found a torrent that doesn't behave good in deluge.
I tested it with version 0.5.8.9 and 0.5.9.0 in Fedora 8 x86_64 (both rpms taken directly from koji builds).
The issue is that even though I'm downloading, it doesn't show any download or upload speed, and also it appears I'm not uploading anything (or at least deluge doesn't show it). Ports are forwarded fine with upnp, deluge works just fine with any other torrent I tried. The torrent in question doesn't appear to be malformed at first sight.
I'm pretty sure I cannot link directly to this torrent in this forum, but if anyone wants to check this out I'll gladly pm it.

Thanks for support!

I'll check it out if there's no other takers...

if you run deluge from terminal and then download that particular torrent, does it output anything out of the normal?
also you said deluge was actually downloading and uploading - how did you observe this? did you use the system network monitor or something more advanced like wireshark?

This is what I get from terminal first starting deluge and then adding the torrent. Some errors about unique_ID - might be that?
Well I observe I'm downloading as the files actually increment their content and not just a bunch of zeroes, uploading I'm not sure if I am, later I'll try a wireshark dump to check it out.
Btw, I'm sending the link to the given torrent to both!

Thanks for support,

I see what you mean about it not showing download or upload speed, but still obviously downloading chunks.
That torrent file seems suspiciously large to me, or maybe due to the number of pieces the files are divided up into. I don't see a reason to have it split into that many pieces, maybe they didn't know what they were doing when they created it.

Something interesting, I went and tried it on Ubuntu 8, with the latest Deluge .6 daily build and it wouldn't create the folder or files.

it was downloading but at a ridiculously slow rate for me.
does anyone know what the minium speed you need to be downloading at for it to show up in deluge?
maybe it's going so slow it doesn't appear

[r1348]

Well no, it's going pretty fast here judging by the network monitor, but speed doesn't show up anyway...
Maybe you're going so slow because 99% of the seeders are in Italy and you're well, on the other side of the world

[johnnyg]

lol, probably.
I did notice that the speed showing when I hovered over the tray icon was frozen (it was showing the speed of the last torrent I was downloading before I started downloading that particular one).

I'm quite sure the bug is triggered by the torrent being composed of 10.000+ parts of 256kB, deluge somehow doesn't handle that correctly.
I know such torrent represents an "edge case", still there's no specification limiting the number of parts, even though I admit that using 256kB parts for 2,5GB of data doesn't make much sense...

Further in-depth inspection coming soon.
