python3-pycxx sets "tp_print", which was removed in Python 3.8.0b1.

pycxx-7.1.2/Src/Python3/cxx_extensions.cxx" contains:
    table->tp_print = 0;

This is only needed on Python 2. Python 3.0-3.7 ignores the field and Python 3.8+ removes the field entirely.


This prevents rebuilding the "pysvn" package. For its build logs, 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 3.8:
