3853,bzip2_decompressor reads only one block of a pbzip2-created files,Darko Veberic <darko.veberic@…>,Jonathan Turkanis,"reading bz2 files created with parallel version ""pbzip2"" stops exactly after correctly decompressing the first bzip block (900k). this same bz2 file is correctly decompressed by the non-parallel bunzip2 version so, imho the bzip2 filter should do the same or throw an exception if this is some kind of unrecognized format.

i've been able to reproduce this bug with boost 1.35.1, 1.36.0, 1.40.0, 1.41.0 so i guess it is present in all versions. the bug can be seen by running the attached programs:

  c++ spit.cc -o spit
  c++ test_bzip2_decompressor.cc -o test_bzip2_decompressor
  ./spit >test.txt
  bzip2 -c test.txt >test.txt.bz2
  pbzip2 -c test.txt >test.txt.parallel.bz2

running
  ./test_bzip2_decompressor test.txt.bz2 | wc
outputs correct 500 lines:
  500  250000  995395
while
  ./test_bzip2_decompressor test.txt.parallel.bz2 | wc
finds only 452 lines and only 900k in total:
