I created a simpler test case that exercises the buggy code. The problem can be reproduced by passing ZipFile.__init__() a file-like object with the write flag (mode "w") and then closing the file-like object before calling ZipFile.close(). The exception being triggered by the call to ZipFile.__del__() is a side-effect because all ZipFile.__del__() does is call ZipFile.close(). import io from zipfile import ZipFile bytes_io = io.BytesIO() zip_file = ZipFile(bytes_io, mode="w") bytes_io.close() zip_file.close() # throws ValueError ---------- Added file: https://bugs.python.org/file49336/zipfile_close_bug.py _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue41350> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
