Description norbert kamenicky 2007-09-11 13:11:33 UTC
It happened to me twice ... 

1. while downloading large torrent (more files, some GB's all together)
   everything looks to be OK and "seeding" starts ...

2. after some time of uploading error about "corrupted data" occurs and 
   automatic "data scanning" starts ...

3. then few "broken" chunks are redownloaded, message about "completed"
   download is displayed and seeding starts again for a while, but
   then it goes to point 2


I was curious what's going on, so I made checksums of all files immediately
after "fail" and also after "successful" redownload, but no diff's
found (as I expected).

So there is a possibility, that "torrent" is broken and data are 
redownloaded broken again and again, but ktorrent should detect it
and solve it in more intelligent way (checking and scanning the some GB's 
of data every 5 minutes, thousends times pro day in neverending loop
is definitely not a solution)




Reproducible: Sometimes

This should be fixed in ktorrent-2.2.2. Please try that and report back.
Comment 2 norbert kamenicky 2007-09-13 22:17:54 UTC
Just emerged and started it, but actually no GUI available
i.e. it runs on background only ...
be patient, I'm gonna to play around.

ok, after removing  ~/.kde3.5/share/config/ktorrentrc it starts with gui 

to check "neverending loop" problem I run "Data integrity check" at first on "problematic torrent", which recognized, that only one file was downloaded

so I loaded "Info widget plugin" and reassigned files to download again,
after few minutes "download was completed", seeding started and then,
guess what ? ... neverending data scanning started again :-(
 

if somebody like to recheck the problem, here is the link to "problematic torrent":

(I downloaded parts 13-22 only)

Please do *not* post links to torrents of questionable legal status.

Please file an upstream bug at http://bugs.kde.org and post its URL here.
