[New-bugs-announce] [issue33653] EnvironmentError does not set errno unless strerror is set

[Giampaolo Rodola']

New submission from Giampaolo Rodola' <g.rodola at gmail.com>:

>>> import errno
>>> OSError(errno.EBADF).errno
>>> OSError(errno.EBADF, "yo").errno
9
>>> IOError(errno.EBADF).errno
>>> IOError(errno.EBADF, "yo").errno
9
>>> EnvironmentError(errno.EBADF).errno
>>> 
>>> EnvironmentError(errno.EBADF, "yo").errno
9

This is a bit annoying mainly when mocking fs-related functions in order to raise specific OSError exceptions.
