py3k.os_fspath enforces inconsist rules with python3 os.fspath
After a recent upgrade of numpy (1.13.1 -> 1.6.0), my code is failing where I provide unicode objects as filenames. Previously they were allowed. Now that are not, and I *must* provide a (py2) str or bytearray only. # str is OK $ python2.7 -c "from numpy.compat import py3k; print py3k.os_fspath('123')" 123 # unicode is not $ python -c "from numpy.compat import py3k; print py3k.os_fspath(u'123')" Traceback (most recent call last): File "<string>", line 1, in <module> File "/usr/local/lib/python2.7/dist-packages/numpy/compat/py3k.py", line 237, in os_fspath "not " + path_type.__name__) TypeError: expected str, bytes or os.PathLike object, not unicode But this enforcement of "str, bytes or os.PathLike" comes from: https://docs.python.org/3/library/os.html where in Python 3 str is a unicode, and moreover, os.fspath allows $ python3 -c "import os; print(os.fspath(u'123'))" # unicode str 123 $ python3 -c "import os; print(os.fspath('123'))" # also unicode str 123 .... so... shouldn't py3k.os_fspath allow py2 unicode obejcts. - Stu
