Motivation for this change
Didn't build on py3.7.
The pypi package we were using includes pre-cythonized versions of some components, however these were cythonized with a py3.7-unaware cython which is what caused the main breakage. Fetching the equivalent version from github allows us to offer either the pure-python version or one we cythonize ourselves dependent on whether the
cython
package is provided.The added bonus of using a github checkout is that the tests are included, so I've enabled these.
These tests revealed that for full py3.7 compatibility an additional patch is needed from an upstream PR - added.
I've done a
nox-review
on this and there's one depending package (worldengine
) that still doesn't build. Think I can probably fix that another time.Things done
