[New-bugs-announce] [issue12802] Windows error code 267 should be mapped to ENOTDIR, not EINVAL

[Antoine Pitrou]

New submission from Antoine Pitrou <pitrou at free.fr>:

Windows error 3 is returned when a directory path doesn't exist, but 267 is returned when an existing path is not a directory. This corresponds straight to the definition of ENOTDIR, but Python translates it to EINVAL:

>>> os.listdir("xx")
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
WindowsError: [Error 3] The system cannot find the path specified: 'xx\\*.*'

>>> os.listdir("LICENSE")
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
WindowsError: [Error 267] The directory name is invalid: 'LICENSE\\*.*'

>>> os.chdir("LICENSE")
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
WindowsError: [Error 267] The directory name is invalid: 'LICENSE'

>>> e = sys.last_value
>>> e.errno
22
>>> errno.errorcode[22]
'EINVAL'


In PC/errmap.h, no Windows error code is translated to ENOTDIR (errno 20).
