Description Tomáš Hrnčiar 2023-03-07 15:22:51 UTC
fail2ban fails to build with Python 3.12.0a5.

+ /usr/bin/python3 bin/fail2ban-testcases --verbosity=2 --no-network
Traceback (most recent call last):
  File "/builddir/build/BUILD/fail2ban-1.0.2/bin/fail2ban-testcases", line 40, in <module>
    from fail2ban.tests.utils import getOptParser, initProcess, gatherTests
  File "/builddir/build/BUILD/fail2ban-1.0.2/fail2ban/tests/utils.py", line 46, in <module>
    from ..server import asyncserver
  File "/builddir/build/BUILD/fail2ban-1.0.2/fail2ban/server/asyncserver.py", line 28, in <module>
    import asynchat
ModuleNotFoundError: No module named 'asynchat'

asynchat and asyncore have been removed according to the schedule in PEP 594, having been deprecated in Python 3.6. Use asyncio instead. (Contributed by Nikita Sobolev in gh-96580.)

For all our attempts to build fail2ban with Python 3.12, see:
https://copr.fedorainfracloud.org/coprs/g/python/python3.12/package/fail2ban/

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.

Reported upstream

Comment 2 Fedora Release Engineering 2023-08-16 07:11:09 UTC
This bug appears to have been reported against 'rawhide' during the Fedora Linux 39 development cycle.
Changing version to 39.
