Description Miro Hrončok 2020-02-28 09:54:24 UTC
fail2ban fails to build with Python 3.9.0a4.

ERROR: test_del_file (fail2ban.tests.filtertestcase.MonitorFailures<FilterPoll>(/tmp/monitorfailures_FilterPoll__nshi9c2fail2ban))
Traceback (most recent call last):
  File "./fail2ban/tests/filtertestcase.py", line 987, in setUp
  File "./fail2ban/tests/filtertestcase.py", line 1008, in _sleep_4_poll
    Utils.wait_for(self.filter.isAlive, _maxWaitTime(5))
AttributeError: 'FilterPoll' object has no attribute 'isAlive'

And more. This looks like:

See https://docs.python.org/3.9/whatsnew/3.9.html#removed

"The isAlive() method of threading.Thread has been removed. It was deprecated since Python 3.8. Use is_alive() instead."

For the build logs, see:

For all our attempts to build fail2ban with Python 3.9, 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 3.9:

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.
