If a path has a non-existent anchor, Path.mkdir can get into a RecursionError as it tries to recursively create the parent. I expect a more sane error.
This is readily reproducible in Windows with `Path('Z:').mkdir(parents=True)`
Example execution:
Python 3.6.0 (v3.6.0:41df79263a11, Dec 23 2016, 08:06:12) [MSC v.1900 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> from pathlib import Path
>>> Path('Z:').mkdir(parents=True)
Traceback (most recent call last):
File "C:\Python36\lib\pathlib.py", line 1231, in mkdir
self._accessor.mkdir(self, mode)
File "C:\Python36\lib\pathlib.py", line 388, in wrapped
return strfunc(str(pathobj), *args)
FileNotFoundError: [WinError 3] The system cannot find the path specified: 'Z:'

Might be worth checking if this is resolved with issue29079, which is already in for 3.6.1. |

This case is similar to issue 29079. It should only attempt to make the parent to handle ENOENT if self and self.parent aren't equal. Here's the snippet from Path.mkdir: try: self._accessor.mkdir(self, mode) except FileExistsError: if not exist_ok or not self.is_dir(): raise except OSError as e: if e.errno != ENOENT: raise self.parent.mkdir(parents=True) self._accessor.mkdir(self, mode) |
