[New-bugs-announce] [issue41640] module zipfile issue on closing

[Bastian Ebeling]

New submission from Bastian Ebeling <bastian.ebeling at gmail.com>:

When trying to open an archive and read internal binary streams, for me it occurs, that the file-stream gets closed.
As a code-Snippet:

import zipfile
srcfile=zipfile.ZipFile('file.zip')
a=zipfile.Path(srcfile,"data1.bin").read_bytes()
b=zipfile.Path(srcfile,"data2.bin").read_bytes()

the second call results in the ValueError: seek of closed file

A quick and dirty solution (as an idea) is to change close() for the _SharedFile to run self.close() instead of self._close(findeobj) in the end (somehow around line 772).

Hopefully that helps
