python-bsddb3 fails to build with Python 3.12.0a3.

+ /usr/bin/python3 test.py
Traceback (most recent call last):
  File "/builddir/build/BUILD/bsddb3-6.2.9/test3.py", line 153, in <module>
    from unittest.runner import _TextTestResult
ImportError: cannot import name '_TextTestResult' from 'unittest.runner' (/usr/lib64/python3.12/unittest/runner.py). Did you mean: 'TextTestResult'?

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "/builddir/build/BUILD/bsddb3-6.2.9/test.py", line 42, in <module>
    import test3 as test
  File "/builddir/build/BUILD/bsddb3-6.2.9/test3.py", line 155, in <module>
    from unittest import _TextTestResult
ImportError: cannot import name '_TextTestResult' from 'unittest' (/usr/lib64/python3.12/unittest/__init__.py). Did you mean: 'TextTestResult'?

Removed many old deprecated unittest features:

    - A number of TestCase method aliases:

    You can use https://github.com/isidentical/teyit to automatically modernise your unit tests.

    - Undocumented and broken TestCase method assertDictContainsSubset (deprecated in Python 3.2).

    - Undocumented TestLoader.loadTestsFromModule parameter use_load_tests (deprecated and ignored since Python 3.2).

    - An alias of the TextTestResult class: _TextTestResult (deprecated in Python
3.2).

For all our attempts to build python-bsddb3 with Python 3.12, see:

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 3.12:
https://copr.fedorainfracloud.org/coprs/g/python/python3.12/

Let us know here if you have any questions.

Python 3.12 is planned to be included in Fedora 39. To make that update smoother, we're building Fedora packages with all pre-releases of Python 3.12.
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.
