feat: upgrade docker image to py38 and add support for py39 #16889

villebro · 2021-09-29T07:25:00Z

SUMMARY

With Python 3.10 right around the corner (2021-10-04) and multiple performance improvements when going from 3.7 to 3.8 (see Python Speed Center benchmark summary below), we should move to 3.8 and start preparing for transitioning to 3.9. This PR bumps the official image from Python 3.7 to 3.8 and adds support for Python 3.9. CI is also bumped from 3.7 to 3.8 (btw, tox was already confgured with basepython = python3.8), and dual tests for 3.7 and 3.8 are replaced with 3.8 and 3.9.

Performance benchmark

On most benchmark tests, 3.8 (blue) performs slightly better than 3.7 (orange):

-sqlalchemy-utils==0.36.8
+sqlalchemy-utils==0.37.8


sqlalchemy-utils==0.36.8 has been yanked from PyPI, causing an ugly warning when installing deps. In addition, py39 was added to the officially supported versions right after 0.37.8 was cut (kvesteri/sqlalchemy-utils@b5b48b1), so I assume 0.37.8 to be fully supported by 3.9 in practice.

superset/utils/memoized.py

-        return functools.partial(self.__call__, obj)
+        func = functools.partial(self.__call__, obj)
+        func.__func__ = self.func  # type: ignore
+        return func


I wasn't quite able to figure out why this is necessary, but running doctests on memoized methods started failing on 3.9 due to the doctests failing to find the __func__ attribute on memoized methods. The only thing I found is this which seems like the same problem, but is said to affect Python 3.8, not 3.9: https://bugs.python.org/issue12790 Hacky workaround, but does the trick. I'll try to figure out how to solve this more elegantly before this gets merged

"Programming Language :: Python :: 3.7",

I think we're still going to support 3.7 (we support last 3 python versions officially). Once 3.10 is out, we'll remove 3.7 support in a major version bump

I want to deprecate 3.7 too, but I think we should give it some more time (it's still currently the recommended version) - let's leave it alive for a month or so so everyone can get upgraded to at least 3.8

@etr2460 @villebro do we—Apache Superset—have an official policy about supporting the last three Python versions? Just asking. If that's the case I think this is great as it means we're not unnecessarily burdened by older less feature rich versions.

@john-bodley @etr2460 I think we just lightly agreed on the last 3 versions on a community meeting. Making it an official policy is a good idea to let users know what to expect and plan ahead

@john-bodley TBH until this PR we were only really supporting two 😄 But yeah, I think there was an unwritten agreement to try to support 3. I'm fine cutting it down to "at least 2" but trying to support 3 if possible.
