Python 3.9

[henryiii]

Rebased from #64, I don't seem to be able to push to that one for some reason.

• Add .ci_support/migrations/python39.yaml
• Remove numpy<1.19 test constraint
• MNT: Re-rendered with conda-build 3.21.4, conda-smithy 3.9.0, and conda-forge-pinning 2021.03.12.19.24.49

Hi! This is the friendly automated conda-forge-linting service.

I just wanted to let you know that I linted all conda-recipes in your PR (recipe) and found it was in an excellent condition.

[henryiii]

was in an excellent condition

Not really, the build number didn't get bumped. :)

[henryiii]

Oh, that's a test constraint, never mind, no build number bump needed.

[jakirkham]

That's ok. We don't need to bump the build number for this

[henryiii]

I believe there's one very minor error in test reporting in NumPy 1.19 that was discussed in numba/numba#5929 was fixed in numpy/numpy#17457 but never backported to the 1.19 series. Before Python 3.9, we could just pin <1.19 and avoid it. Now with Python 3.9, only 1.19 and 1.20 support that version, so to run the tests, we need one of the two versions.

NumPy 1.20 may have fixed this one minor test error, but it seems to have introduced 10 new errors, so that's even worse.

[henryiii]

My current thought would be to pin <1.20, and then filter the broken test. Better than filtering 10 tests.

[henryiii]

Here are the 10 failing tests for 1.20:

[henryiii]

Or maybe 3.9 works with that limiting, maybe I just didn’t see the backport.

(timeout issue with drone)

[henryiii]

Looks like it's working except for Travis, which gives "Job has been terminated due to insufficient credits balance".

[jakirkham]

Yeah that is a known issue ( conda-forge/status#110 )

[henryiii]

I could swap out Travis for cross compilation. PyPy isn't supported yet but Numba doesn't support PyPy AFAIK. Probably will give it a day to see if the issue gets worked out?

[jakirkham]

Sure. Also ok with just merging and restarting on master once it clears

[henryiii]

I’d be okay with that, too
