File "/home/apy/ActivePython-2.6/lib/python2.6/gzip.py", line 24, in
read32
return struct.unpack("<I", input.read(4))[0]
error: unpack requires a string argument of length 4
The gzip.read32() function has been removed in Python 3:

Issue #1159051: GzipFile now raises EOFError when reading a corrupted file
with truncated header or footer.
Added tests for reading truncated gzip and bzip2 files.

File "/home/apy/ActivePython-2.6/lib/python2.6/tarfile.py", line
2307, in next
self.fileobj.seek(self.offset)
File "/home/apy/ActivePython-2.6/lib/python2.6/gzip.py", line 382, in
seek
self.read(1024)
Moreover, gzip.GzipFile().seek() no longer calls self.read(1024):

Issue #23529: Limit the size of decompressed data when reading from
GzipFile, BZ2File or LZMAFile. This defeats denial of service attacks
using compressed bombs (i.e. compressed payloads which decompress to a huge
size).
Patch by Martin Panter and Nikolaus Rath.
IMO it's no longer possible to reproduce the gzip.error on
gzip.GzipFile.seek(), so I close the issue as out of date.
----------
resolution: -> out of date
stage: test needed -> resolved
status: open -> closed
