There is a problem in the "0001-3.9-gh-109858-Protect-zipfile-from-quoted-overlap-zi.patch" file added in the security update.

That patch file was backported from the code added for Python 3.9.

The notation of decorator "@requires_zlib()" is correct in Python 3.9, but not in Python 3.7.
The correct notation is "@requires_zlib".

The test_zipfile crashed log:
  # python3 -m test -v test_zipfile
  ...
  test test_zipfile crashed -- Traceback (most recent call last):

Thanks.
