random 64 bytes of NUL appended to only .r08 files
« on: May 25, 2015, 09:47:21 AM »
this is a very strange bug that i've experienced a few dozen times over the years.  it has persisted across several versions of Alt.Binz, different Windows installs, and new hard drives.

my download will complete properly.. all files will verify with the .par2, the archive will be extracted with no checksum errors, and everything appears fine.

however... sometimes the .r08 will be 64 bytes oversized. looking at the file with an editor shows them as NUL bytes: http://imgur.com/x00B0Zf.png

the .sfv for the download will not verify at that point.. and if i remove the 64 bytes of NUL and save the file, then all is fine.

i haven't been able to track down any other hints that would help squash this bug.. but the fact that it has only ever happened on .r08 files could be a good starting point.

I would need example posts. The more, the better. Please upload NZB files somewhere and send me the link via pm.

I've tried few of them (that were not dmca-ed) and everything is normal here.
I don't see how it's possible to pass par2 check and be oversized.

Can you reproduce the problem with same nzbs every time?
