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

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.

This could be due to https://bugs.python.org/issue34318

I cannot even run stestr, to be honest:

Has it been patched in Fedora already?

Comment 3 Dmitry Tantsur 2020-03-02 15:43:10 UTC

Anyway, I think I've figured it: https://review.opendev.org/#/c/710802/

Comment 4 Miro Hrončok 2020-03-02 16:22:49 UTC

> AttributeError: module 'collections' has no attribute 'MutableMapping'

You should not see this with 3.9.0a4. The Fedora build of python39 3.9.0a4 is coming to updates-testing as we speak.

Comment 5 Miro Hrončok 2020-05-25 13:01:17 UTC

This comment is mass posted to all bugs blocking the Python 3.9 tracker, sorry if it is not 100 % relevant. When in doubt, please ask.


The Python 3.9 rebuild is in progress in a Koji side tag.

If you fix this bug, please don't rebuild the package in regular rawhide, but do it in the side tag with:

    $ fedpkg build --target=f33-python

The rebuild is progressing slowly and it is possible this package won't have all the required build dependencies yet. If that's the case, please just leave the fix committed and pushed and we will eventually rebuild it for you.

You are not asked to go and try rebuild all the missing dependencies yourself. If you know there is a bootstrap loop in the dependencies, let me know and we can untangle it together.

If you want to test your fix or reproduce the failure, you can still use the Copr repo mentioned in the initial comment of this bug: https://copr.fedorainfracloud.org/coprs/g/python/python3.9/

Comment 6 Dmitry Tantsur 2020-05-25 16:20:23 UTC

Hi Miro,

The fix has been included in an upstream release. Should we just update the version in rawhide or is something else required?

Comment 7 Miro Hrončok 2020-05-25 17:08:32 UTC

> Should we just update the version in rawhide

Yes. Except don't build it in rawhide, only push it. Thanks.

Comment 8 Dmitry Tantsur 2020-05-26 10:09:55 UTC

Pushed 2.0.3 (a bit conservative to avoid a major bump right now).

Comment 9 Miro Hrončok 2020-05-26 12:31:22 UTC

Thanks.
