[Jython-bugs] [issue2176] bz2 compressed tarfile can see a corrupted read

[Jim B. <re...@bu...>]

New submission from Jim Baker:

It's trivial to reproduce this bug:

wget https://pypi.python.org/packages/source/P/PrettyTable/prettytable-0.7.2.tar.bz2#md5=760dc900590ac3c46736167e09fa463a

import tarfile

with tarfile.open(name='prettytable-0.7.2.tar.bz2', mode='r') as t:
    t.extractall()

will reliably produce output files with chunks of data missing, as can be readily be verified with diff -r

Note that using the bz2 module to decompress produces a valid tar, so there's likely some interaction between streaming decompress and output of a given block to the untarred directory.
