New submission from Roy Williams:
I am investigating a migration to Python 3, and to facilitate this we are using the -3 flag as decribed here: https://docs.python.org/3/howto/pyporting.html#prevent-compatibility-regressions . When using this flag I encountered
some issues inside of mock itself.
Python 3 now requires you to implement __hash__ if you implement __eq__. See https://docs.python.org/3.6/reference/datamodel.html#object.%5F%5Fhash%5F%5F .
{mock.ANY} # Fine in Python 2, Throws in Python 3
I've created a PR that explicitly sets the __hash__ method on these objects as None to ensure the behavior is consistent in Python 3 as well as Python 2. The folks over at testing-in-python suggested I submit a bug here first and then the fix can be backported to testing-cabal/mock
