Running easy_install on pyOpenSSL-0.6.tar.gz ends with:
File "/usr/local/stow/python-release25-maint-2008-05-30/lib/python2.5/site-packages/setuptools-0.6c8-py2.5.egg/setuptools/command/easy_install.py", line 626, in install_eggs unpack_archive(dist_filename, tmpdir, self.unpack_progress) File "/usr/local/stow/python-release25-maint-2008-05-30/lib/python2.5/site-packages/setuptools-0.6c8-py2.5.egg/setuptools/archive_util.py", line 67, in unpack_archive driver(filename, extract_dir, progress_filter) File "/usr/local/stow/python-release25-maint-2008-05-30/lib/python2.5/site-packages/setuptools-0.6c8-py2.5.egg/setuptools/archive_util.py", line 192, in unpack_tarfile tarobj._extract_member(member,dst) # XXX Ugh File "/usr/local/stow/python-release25-maint-2008-05-30/lib/python2.5/tarfile.py", line 1656, in _extract_member self.chmod(tarinfo, targetpath) File "/usr/local/stow/python-release25-maint-2008-05-30/lib/python2.5/tarfile.py", line 1777, in chmod raise ExtractError("could not change mode of %s to mode %o (octal), exception: %s" % (targetpath, tarinfo.mode, e)) tarfile.ExtractError: could not change mode of /tmp/easy_install-4yCggq/pyOpenSSL-0.6 to mode 2755 (octal), exception: [Errno 1] Operation not permitted: '/tmp/easy_install-4yCggq/pyOpenSSL-0.6'
If I untar that tarball with GNU tar, I see that there is one file that doesn't have read permissions for user or group:
... -rw-r--r-- martin/martin 1289 2002-09-07 09:28:12 pyOpenSSL-0.6/examples/simple/client.py -rw-r--r-- martin/martin 1863 2004-07-22 06:01:25 pyOpenSSL-0.6/examples/proxy.py -rw------- martin/martin 3508 2002-09-07 09:27:47 pyOpenSSL-0.6/examples/SecureXMLRPCServer.py -rw-r--r-- martin/martin 260 2004-07-22 06:01:25 pyOpenSSL-0.6/__init__.py ...
If I rebuild that tarball with GNU tar ("tar czvvf pyOpenSSL-0.6.tar.gz pyOpenSSL") then the resulting tarball does not have that problem.
So, I don't understand it, but there is something funny in the permissions in that official pyOpenSSL-0.6.tar.gz (from http://sourceforge.net/project/showfiles.php?group_id=31249 ) which causes this exception inside tarfile but which goes away if you unpack and repack the tarball on Mac OS X using GNU tar v1.14.
This is probably more of a bug in tarfile.py than in setuptools proper, but I thought I should register this issue on the setuptools tracker so that we can think of some workaround to deploy before this gets fixed in Python tarfile.py and everyone in the world upgrades to the new tarfile.py...
