Description Karolina Surma 2025-01-06 15:04:24 UTC

python-lxml fails to build with Python 3.14.0a3 (since a1) because of a test failure.
Note we have a successful build without tests.

Opening this here for tracking purposes.

Comment 1 Miro Hrončok 2025-01-06 15:15:51 UTC

https://github.com/lxml/lxml/commit/9e95960cd69a3e0393f4266d60a6f5a2a755de0d fixes one of the failures reported upstream. The other one might no longer happen. Will check.

Comment 2 Miro Hrončok 2025-01-06 15:23:20 UTC

OK, the other failure seems gone. https://src.fedoraproject.org/rpms/python-lxml/pull-request/45

Comment 3 Miro Hrončok 2025-01-06 16:13:06 UTC

Fixed in distgit.
