Not Python 2.6 compatible #36

Closed kynan closed 10 years ago

kynan commented 11 years ago

The core_types extension module is not compatible with Python 2.6 due to the use of capsules, which were introduced in 2.7.

A possible workaround would be introducing a compatibility header that redefines PyCapsule C API calls in terms of PyCObject.

Fixed in c2415d3

kynan commented 11 years ago

Turns out this isn't quite fixed yet. For reasons I can't quite tell the build on 2.6 still fails.

I sort of don't care about this. 2.7 is not /that/ new. Is there a compelling reason to tie ourselves in knots to support 2.6? I'd be more worried about forward compatibility to 3.4.

kynan commented 10 years ago

There's certainly no reason to care about 2.6 other than deploying to clusters. I agree that we should rather start worrying about forward compatibility.

ggorman commented 10 years ago

I believe the future for deployment on clusters and supercomputers is via python platforms such as Anaconda. This is resolving many ongoing python/numpy/scipy issues for us on HECToR/ARCHER. In addition, Andy Terrel and Continuum are working with Cray to sort out scalability etc. so this approach is gaining momentum.

ie - we really don’t care about 2.6 etc.

kynan commented 10 years ago

Yes, if we could have a recent Anaconda distribution on HPC clusters that would be fantastic. With that 2.6 would not be a concern, but we should keep forward compatibility in mind.

wence- commented 10 years ago

Closing this, since we've decided we don't care enough about 2.6
