umask option for tarfile extract

Hello,

While extracting a tar file, is there a way to give an umask option for
creating the non-existing upper directories of the file within the tar
archive.

The default behaviour is to create the directories with 0777 permission bits.

Code taken from tarfile.py of python version 2.4.3:

# Create all upper directories.
upperdirs = os.path.dirname(targetpath)
if upperdirs and not os.path.exists(upperdirs):
ti = TarInfo()
ti.name = upperdirs
ti.type = DIRTYPE
ti.mode = 0777
^^^^^^
ti.mtime = tarinfo.mtime
ti.uid = tarinfo.uid
ti.gid = tarinfo.gid
ti.uname = tarinfo.uname
ti.gname = tarinfo.gname
try:
self._extract_member(ti, ti.name)
except:
pass

Regards,
- Faik
