For the build logs, see:
https://copr-be.cloud.fedoraproject.org/results/@python/python3.10/fedora-rawhide-x86_64/02124475-grpc/

For all our attempts to build grpc with Python 3.10, see:
https://copr.fedorainfracloud.org/coprs/g/python/python3.10/package/grpc/

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 3.10:
https://copr.fedorainfracloud.org/coprs/g/python/python3.10/

Let us know here if you have any questions.

Python 3.10 will be included in Fedora 35. To make that update smoother, we're building Fedora packages with early pre-releases of Python 3.10.
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.

Comment 1 Ben Beasley 2021-04-22 02:28:21 UTC

I have verified that the update to grpc 1.37.0 (RHBZ#1794566) will resolve the Python 3.10 issues. See that bug for status; it is blocked on a dependent package fix, but the intent is to complete it in the next few weeks.

Comment 2 Ben Beasley 2021-04-22 12:09:35 UTC

Sorry, I posted prematurely. I can’t build with Python 3.10 yet because python-google-auth isn’t yet available in the Python 3.10 COPR.

Comment 3 Tomáš Hrnčiar 2021-04-22 12:50:20 UTC

I triggered python-google-auth rebuild in COPR and the latest version of it is available now. To easily test grpc with Python 3.10. you can open PR to update grpc in dist-git and it will trigger rebuild in Python 3.10. COPR. It will be available here: https://copr.fedorainfracloud.org/coprs/g/python/python3.10/builds/?dirname=python3.10:pr:3 (3 is number of opened PR in dist-git component).

Comment 4 Ben Beasley 2021-04-25 13:08:45 UTC

Thanks, that helped! I am now working through a few remaining test failures; some from Python 3.10, some specific to arm and/or s390x.

I am treating a working Python 3.10 build (even if I skip a few tests without understanding the real problem) as a precondition for merging the 1.37 update into Fedora 35.

It’s a fussy package, and rebuilds take a long time, but it shoudn’t be too much longer.

Comment 5 Fedora Update System 2021-05-26 15:15:54 UTC

FEDORA-2021-73491747ee has been pushed to the Fedora 35 stable repository.
