New submission from Maciej Misiak <maciej.mm.mis...@gmail.com>:
This code is incomplete:
def _init_write_gz(self):
...
if self.name.endswith(".gz"):
self.name = self.name[:-3]
# RFC1952 says we must use ISO-8859-1 for the FNAME field.
self.__write(self.name.encode("iso-8859-1", "replace") + NUL)
If it is used in following way '.gz' is stripped properly and
FNAME='somefile.tar':
tarfile.open('somefile.tar.gz', 'w:gz')
but with
tarfile.open('somefile.tgz', 'w:gz')
FNAME is incorrectly prepared as somefile.tgz
