Description Miro Hrončok 2021-01-06 18:49:54 UTC
python-jsonpickle fails to build with Python 3.10.0a4 and Python 3.9.1. This seems related to the updated NumPy.

For the build logs, see:
https://copr-be.cloud.fedoraproject.org/results/@python/python3.10/fedora-rawhide-x86_64/01865152-python-jsonpickle/

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

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.

Adding to BZ fails with RPC error.

Comment 2 Ben Cotton 2021-02-09 15:37:39 UTC
This bug appears to have been reported against 'rawhide' during the Fedora 34 development cycle.
Changing version to 34.
