pcs fails to build with Python 3.9.0a5.

AttributeError: type object '_FailedTest' has no attribute 'pcs_test'

Ran 5527 tests in 971.441s

FAILED (errors=1, skipped=13)

For all our attempts to build pcs 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.

Comment 1 Ondrej Mular 2020-03-27 14:35:08 UTC

Thank you for reporting this issue. The reason of this failure is removal of xml.etree.cElementTree module in Python 3.9 [1], which was used in pcs test suite.
