Re: [Security-sig] PEP: Make os.urandom() blocking on Linux (version 2)

Expected usage to write portable code::

def my_random(n): if hasattr(os, 'getrandom'): return os.getrandom(n, 0) return os.urandom(n)

I would actually expect that this would be handled in the secrets module, so the recommendation would be that most users wouldn't use os.urandom() or os.getrandom() unless they specifically wanted the low-level functions and knew what they were doing. Thus, "expected usage to write portable code" would be to use secrets.token_bytes().

Oh ok. I will update this section. Victor
