[New-bugs-announce] [issue22299] resolve() on Windows makes some pathological paths unusable

[Kevin Norris]

New submission from Kevin Norris:

Run Python as an administrator:

    >>> import pathlib 
    >>> pth = pathlib.Path('//?/C:/foo.')
    >>> pth.mkdir()
    >>> pth.resolve().rmdir()
    Traceback (most recent call last):
      File "<stdin>", line 1, in <module>
      File "C:\Python34\lib\pathlib.py", line 1141, in rmdir
        self._accessor.rmdir(self)
      File "C:\Python34\lib\pathlib.py", line 323, in wrapped
        return strfunc(str(pathobj), *args)
    FileNotFoundError: [WinError 2] The system cannot find the file specified: 'C:\\foo.'
    >>> pth.rmdir()

You do not need to be an administrator so long as you can create a directory in the requested location, but the \\?\ prefix only works with absolute paths so it's easier to demonstrate in the root of the drive.
