Hi, I've been playing with my Cython-generated extension on PyPy, trying to load it through CPyExt, and, surprisingly, after a few fixes to PyPy, it generally seems to work.
However, it looks like the situation with whatever kind of arrays is actually pretty gloomy at the moment. First, PyPy supports Python array.arrays, but doesn't replicate Python internals, so the extension even fails to load, since in PyPy tp_basicsize == 16 and not 56. Not sure what to make of this one... for my needs, that would be enough. I guess PyPy developers have to be approached to see if it's practical to expose CPython structure, or agree on a different API? Second, they say that the new-style buffer access is broken and it's not clear if they will support it at all & when this is going to happen. Third, apparently, there is already some limited support for NumPy C-API in NumPyPy, and it seems that there is interest in improving this support to make it usable: http://docs.scipy.org/doc/numpy/reference/c-api.array.html Finally, GetItem on NumPyPy arrays, which will be very slow, but at least should work, rather than not, is also broken. I think this will be easiest of all to fix. So my question is, has anyone been playing with PyPy recently? Is there anyone interested in making Cython-generated code to work nicely with CPyExt? What are the plans w.r.t. the points I mentioned? I've noticed that PyPy jobs in Jenkins are disabled... not sure whether this really means anything or not. Thanks! -- Sincerely yours, Yury V.
