[issue12926] tarfile tarinfo.extract*() broken with symlinks

2011-09-07 Thread Fabio Erculiani 

New submission from Fabio Erculiani lx...@sabayonlinux.org:

TarFile.makelink() is plain broken.
Test file: 
http://git.sabayon.org/entropy.git/tree/libraries/tests/packages/amarok-2.2.2.90.tbz2

_extract_member calls makelink which does os.symlink() and then falls to the 
else branch and calls back _extract_member(), which calls makelink() which 
calls os.symlink() and causes errno 17.

ERROR: test_db_insert_compare_match_mime (__main__.EntropyRepositoryTest)
