python-tornado fails to build with Python 3.8.0b1. See https://copr.fedorainfracloud.org/coprs/g/python/python3.8/package/python-tornado/ for actual logs. This report is automated and not very verbose, but I'll get back here with details.

This issue is blocking the Python 3.8 rebuilds. If this package won't build with 3.8, it won't be installable, along with all its dependent packages, after the side tag is merged. Furthermore, as it fails to install, its dependent packages will fail to install and/or build as well. The fix should be pushed on the master branch and no release bump is required. 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 3.8: https://copr.fedorainfracloud.org/coprs/g/python/python3.8/ This issue needs to be resolved by next week, if other rebuilds of Python 3.8 beta 1 go well. If this is unrealistic for you, let us know how much time you need.
