I'm currently trying to port the pep3118 ctypes changes which are already in the py3k branch to the trunk.

In py3k the tests for this stuff (in Lib/ctypes/test/testpep3118.py) use the memoryview object which exposes attributes like .format, .shape, .strides and so on for objects implementing the new buffer interface. In Python 2.6 memoryview does not exist so the question is how to write a test that checks for the correct attributes. My idea is to implement the arrayinterface property for ctypes instances, as described in this document http://numpy.scipy.org/arrayinterface.shtml.

In private email Travis told me that he has no time to backport the memoryview object to Python 2.6. Maybe there is someone who could do this (Myself I have no time either for this)?
