Negative number of Seeders

[hce]

When downloading this torrent: http://cdimage.debian.org/debian-cd/5.0.7/amd64/bt-dvd/debian-507-amd64-DVD-4.iso.torrent I saw -10 seeders (negative number) listed in the webui.

I tried to reproduce this one, and grab the output from the tracker. But the tracker did respond with all positive values that got reflected correctly. Can you reproduce it reliably?

[hce]

No, unfortunately I cannot. The negative value has disappeared in my torrent listing, too. I've seen it three times so far, -10 in every case, each time a debian torrent...

If it reoccurs, here is what to do:

1. Install the eper suite with redbug.

2. Stop the currently running etorrent session, remove all .torrent files from it

3. Build a remote node for query

   erl -name 'rb@127.0.0.1' -remsh 'etorrent@127.0.0.1' -setcookie etorrent
   

4. Redbug the response handler from the tracker

redbug:start("etorrent_tracker_communication:handle_tracker_response/4",
                  [{time, 60000}]).

5. Add the torrent.
6. See if the tracker response has negative values.

Of course this narrowing won't work if it is even more flaky. I could add a guard on the counts perhaps as an alternative.

This one is too old that I care for it anymore. The code in and around that base has been changed a lot, so I don't expect the problem to be the same in any case. Closing.
