I am still not convinced why tarfile needs this kind of a work-around
built in. We talk about a very small number of cases here and the
generator_tools-0.3.5.tar.gz is really broken beyond repair. It is the
only thing that should be fixed here

[Lars] (...) We talk about a very small number of cases here and the

Sure, that is what the pyopenssl folks did -
Lars Gustäbel l...@gustaebel.de added the comment:
Sure, tarfile contains numerous work-arounds for quirky and buggy
archives. Otherwise, it would not be usable in real-life.
But we should not mix up different issues here. tarfile reads and
extracts your generator_tools.tar just fine. Formally,
Sridhar Ratnakumar sridh...@activestate.com added the comment:
[Lars] Sure, there is some functionality in extractall() that addresses
issues with inappropriate permissions, but without this functionality the
archive would not even *extract* cleanly. That is very different from
your problem.

Considering this bug where tarfile fails to set g+s,
https://bugs.launchpad.net/pyopenssl/+bug/236190
a more general approach could be:
tarfile.extractall(safe_perms=True)
where if safe_perms is set, tarfile can 1) ignore
New submission from Sridhar Ratnakumar sridh...@activestate.com:
If a tarball has a-x perms set on its root directory, one cannot access
its contents.
$ tar zxf generator_tools-0.3.5.tar.gz.
$ ls generator_tools-0.3.5/
ls: cannot access generator_tools-0.3.5/README.txt: Permission denied

I don't see why the tarfile case should be different from the tar case.
You can always chmod it later in python, too (with os.walk and
os.chmod). Perhaps the real need is for a recursive chmod in shutil?

As I explained, Viz:
[quote]'(...)the very reason to write a program to extract tarball
(instead of doing it manually) is to automate it .. which
