Category: Python Library Group: Python 2.4 Status: Open Resolution: None Priority: 5 Submitted By: Arve Knudsen (arve_knudsen) Assigned to: Nobody/Anonymous (nobody) Summary: tarfile chokes on ipython archive on Windows Initial Comment: I'm trying to extract files from the latest ipython tar archive, available from http://ipython.scipy.org/dist/ipython-0.7.2.tar.gz, using tarfile. This is on Windows XP, using Python 2.4.3. There is only a problem if I open the archive in stream mode (the "mode" argument to tarfile.open is "r|gz"), in which case tarfile raises StreamError. I'd be happy if this error could be sorted out. The following script should trigger the error: import tarfile f = file(r"ipython-0.7.2.tar.gz", "rb") tar = tarfile.open(fileobj=f, mode="r|gz") try: for m in tar: tar.extract(m) finally: tar.close() f.close( The resulting exception: Traceback (most recent call last): File "tst.py", line 7, in ? tar.extract(m) File "C:\Program Files\Python24\lib\tarfile.py", line 1335, in extract self._extract_member(tarinfo, os.path.join(path, tarinfo.name)) File "C:\Program Files\Python24\lib\tarfile.py", line 1431, in _extract_member self.makelink(tarinfo, targetpath) File "C:\Program Files\Python24\lib\tarfile.py", line 1515, in makelink self._extract_member(self.getmember(linkpath), targetpath) File "C:\Program Files\Python24\lib\tarfile.py", line 1423, in _extract_member self.makefile(tarinfo, targetpath) File "C:\Program Files\Python24\lib\tarfile.py", line 1461, in makefile copyfileobj(source, target) File "C:\Program Files\Python24\lib\tarfile.py", line 158, in copyfileobj shutil.copyfileobj(src, dst) File "C:\Program Files\Python24\lib\shutil.py", line 22, in copyfileobj buf = fsrc.read(length) File "C:\Program Files\Python24\lib\tarfile.py", line 551, in _readnormal self.fileobj.seek(self.offset + self.pos) File "C:\Program Files\Python24\lib\tarfile.py", line 420, in seek raise StreamError, "seeking backwards is not allowed" tarfile.StreamError: seeking backwards is not allowed ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=105470&aid=1527974&group_id=5470 _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
