Python 3 compatibility

[benley]

Fixes #26, #330

[benley]

The one part I'm not sure about in this change is the m_size field in the PyModuleDef _jsonnet struct. Does this module keep internal state in a way that requires an allocation there?

[sparkprime]

m_size == -1 should be OK because all of the state is built up and torn down within the single evaluate call.

Thanks for doing this!

[ant31]

is it merged ?

[benley]

I was wondering that too - maybe the merge happened in piper and we're waiting for MOE or copybara (or something) to run and publish the result back to github?

[sparkprime]

I'm afraid the explanation was more simple than that :) Sorry

[benley]

No worries - thanks for merging :-D

[wiseman]

Thanks for doing this work!

Is there an ETA for a new pypi release with support for Python 3?

[sparkprime]

No plan just yet, if you need it make a bug and we'll figure out if there's anything we should wait for vs just cut it then and there.
