Par2-Repair miscalulating bug
« on: November 11, 2010, 01:40:03 pm »
Over time there has been one bug that is rather odd. Alt.binz downloads a collection, calculates that x blocks are needed, downloads them, tries to repair the post and fails. The reason for failing is:
You have x recovery blocks available
Repair is not possible.
You need y more recovery blocks to be able to repair.

After that everything comes to a hold. If you unpause the necessary blocks manualy the whole process goes through. Going through the log i've found a recent example:


23.10.2010 12:07:53] [PAR2&Unrar] wurst.par2 needs 1 more blocks, 99 available
[23.10.2010 12:07:53] [PAR2&Unrar] wurst.par2 unpaused 1 blocks

It would be nice to see report by altbinz for that set. Was nfo/sfv/srr downloaded? Was any file misnamed? Whos par2.exe was used?
Original par 0.4/tbb multicore 0.4/phpar2 1.x all suffer from the same bug of not detecting certain blocks in some situations.
