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 ;-)

[issue13158] tarfile.TarFile.getmembers misses some entries

Sebastien Binet bi...@cern.ch added the comment:

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.

[issue13158] tarfile.TarFile.getmembers misses some entries

[Sebastien Binet]

New submission from Sebastien Binet bi...@cern.ch:

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...)
