For all our attempts to build python-hypothesis with Python 3.9, see:
https://copr.fedorainfracloud.org/coprs/g/python/python3.9/package/python-hypothesis/

Testing and mass rebuild of packages is happening in copr. You can follow these instructions to test locally in mock if your package builds with Python 3.9:
https://copr.fedorainfracloud.org/coprs/g/python/python3.9/

Let us know here if you have any questions.

Python 3.9 will be included in Fedora 33. To make that update smoother, we're building Fedora packages with early pre-releases of Python 3.9.
A build failure prevents us from testing all dependent packages (transitive [Build]Requires), so if this package is required a lot, it's important for us to get it fixed soon.
We'd appreciate help from the people who know this package best, but if you don't want to work on this now, let us know so we can try to work around it on our side.

Setting the severity to high, because we'd like to proceed with Koji side tag rebuilds really soon.

Taking https://github.com/HypothesisWorks/hypothesis/pull/2441/commits/5e0867c01785929957663b6c425843da415a0c85 and building it in Copr. Thanks.

Apparently, this is not fixing everything and I'll be more patient. Sorry for rushing things.

oof, no worries. I'll try and fix things on my side.

I'll do a couple of things:
- propose upstream start testing against Python 3.9 pre-releases too (they currently test up to 3.8)
- try and follow up until this is fixed properly

Quick question: given Hypothesis' fast churn of releases and the brittleness of their Python 3.9 support right now, once we get a working build should we just freeze it in place and not do further updates?

We should just make sure the update does not introduce a regression with 3.9. When you open a src.fp.o pull request, the copr should attempt to rebuild it automatically.

This particular failure started not with update of hypothesis, but with changes in Python 3.9.

Comment 6 Michel Alexandre Salim 2020-05-20 22:24:20 UTC

noted, I'll do future updates via pull request first and let it sit for -- err, is a day enough, or two?

And yeah, just noticed the error is with 3.9b1. Hopefully future errors are less likely as 3.9 stabilizes.

Comment 7 Miro Hrončok 2020-05-20 22:27:07 UTC

You can observe the results within minutes (hours when the load is too big) in https://copr.fedorainfracloud.org/coprs/g/python/python3.9/builds/?dirname=python3.9:pr:<pr_number> (for example https://copr.fedorainfracloud.org/coprs/g/python/python3.9/builds/?dirname=python3.9:pr:6)

Comment 8 Michel Alexandre Salim 2020-05-21 17:36:07 UTC

5.15.1 fixes this (upstream merged Petr's patch and fixed a couple of additional issues, and now has CI testing against Python 3.9 too).

Comment 9 Miro Hrončok 2020-05-21 20:19:27 UTC

Excellent news!
