Completed torrent still downloads something

[fturco]

I have Transmission 2.82 on a Ubuntu 13.10 system. I have an already downloaded torrent that I added to Transmission for seeding purposes. Despite read-only permissions Transmission still downloaded something (0.36 kB to be exact), and now the share ratio is a meaningless number (over 3 million). I attached a screenshot for a better understanding of my problem. Is this a bug? Is there a workaround? Thank you.

I don't think it's the same problem. Can you elaborate, please?

looking at what we have from trac ticket 5655 I'm not sure where to go with this. Can you tell me how you re-seed the torrents. Is anything from magnet-links, watch directory or scripts?

[fturco]

The torrents that exhibit this problem have not been added as magnet links, but just as traditional .torrent files. I don't use watch directories or scripts (I'm not even sure what they are used for).

I decided to remove Ubuntu and go back to Gentoo. All torrents have been re-added again, and I'm now waiting for the problem to reappear. I'm now using Transmission (Qt version) 2.82 (14160).

All torrents have been re-added again

So did they verify existing data to 100% or not?

[fturco]

Yes, verification of existing data goes OK. The problem happens after some hours seeding the torrent. I can confirm it also happens under Gentoo. Is there some debug information I can obtain in order to help fixing this bug?

If Transmission later finds a corrupt piece while seeding, then that might indicate a equipment problem on your end. In any case, the torrent will pause with a message that a piece has failed its checksum test and you will need to re-verify the data. After that, then the failed piece or pieces would be re-downloaded.

[fturco]

The fact is the torrent doesn't pause or show any error message.

This seems an unusual problem without much leads to go on. My gut feeling is that if it is a direct transmission issue it pertains to threading. If you reproduce the issue 2.82 then try a version 2.77 or prior to try and reproduce; as 2.8x had threading changed. At any rate we need to be able to reproduce and then find the changeset that causes, that is -> if it is a transmission problem.

[fturco]

OK, I removed the ~/.config/transmission and ~/.cache/transmission directories, downgraded Transmission to 2.77-r1 and added torrents again. I will wait a few days for the problem to appear, then I'll report back to you.

There is another report of this bug, so you are not alone.

...and now the share ratio is a meaningless number (over 3 million)...

I made a patch for that GUI to display an additional meaningful sanity "Seed Ratio".

[fturco]

After having seeded my torrents for some days now I can say that Transmission 2.77-r1 doesn't exhibit this problem. So the bug has probably been introduced in later versions.

I'm now testing version 2.80-r1.
