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

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 David Tardon 2021-05-02 17:28:23 UTC

This fails because the code expects that the string representation of an Enum contains the enum name, which is no longer true in 3.10:

# python3.9
Python 3.9.4 (default, Apr  6 2021, 00:00:00) 
[GCC 11.0.1 20210405 (Red Hat 11.0.1-0)] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import enum
>>> Foo = enum.Enum('Foo', (('BAR', 1), ('BAZ', 2)))
>>> str(Foo.BAR)
'Foo.BAR'

# python3.10
Python 3.10.0a7 (default, Apr  6 2021, 00:00:00) [GCC 11.0.1 20210418 (Red Hat 11.0.1-0)] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import enum
>>> Foo = enum.Enum('Foo', (('BAR', 1), ('BAZ', 2)))
>>> str(Foo.BAR)
'BAR'

Is this change expected?

Never mind, found it: https://docs.python.org/3.10/whatsnew/3.10.html#enum ...
