hi there, it seems tarfile in python 3.2.2 (as installed in archlinux, but I don't see any additional patch applied on top of the vanilla sources: http://projects.archlinux.org/svntogit/packages.git/tree/trunk/PKGBUILD?h=packages/python ) has troubles giving the complete content of a tar ball. see: $ wget http://downloads.sourceforge.net/sourceforge/boost/boost_1_44_0.tar.gz $ md5sum boost_1_44_0.tar.gz 085fce4ff2089375105d72475d730e15 boost_1_44_0.tar.gz $ python --version Python 3.2.2 $ python2 --version Python 2.7.2 $ python ./foo.py >>> 8145 $ python2 ./foo.py >>> 33635 where foo.py is: ## import tarfile o = tarfile.open("boost_1_44_0.tar.gz") print(">>> %s" % len(o.getmembers())) o.close() ## EOF ## is it a known bug ? (this of course prevents TarFile.extractall to be useful w/ python3...) -s

one interesting additional piece of information is that if I un-tar that file and re-tar it w/o gzip compression, getmembers gets the right answer. -s

Thanks for the report. There was a problem decoding a special and rare kind of header field in the archive. The format of the archive is of very bad quality BTW ;-)
