[New-bugs-announce] [issue22201] python -mzipfile fails to unzip files with folders created by zip

[Antony Lee]

New submission from Antony Lee:

With Python 3.4.1:

$ mkdir foo; zip -r foo{,}; python -mzipfile -e foo.zip dest
  adding: foo/ (stored 0%)
Traceback (most recent call last):
  File "/usr/lib/python3.4/runpy.py", line 170, in _run_module_as_main
    "__main__", mod_spec)
  File "/usr/lib/python3.4/runpy.py", line 85, in _run_code
    exec(code, run_globals)
  File "/usr/lib/python3.4/zipfile.py", line 1799, in <module>
    main()
  File "/usr/lib/python3.4/zipfile.py", line 1777, in main
    with open(tgt, 'wb') as fp:
IsADirectoryError: [Errno 21] Is a directory: 'dest/foo/'

Note that zipfile is actually able to unzip the file:

$ python -c 'from zipfile import *; ZipFile("foo.zip").extractall("dest")'

works fine.

If the zip file is created by "python -mzipfile -c foo.zip foo" then there is no problem.  Likewise, if there are no folders in the zip file (but just a collection of files) then there is no problem.
