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.

If you don't have free cycles to dedicate fixing your package, notify us and we'll try to provide some pointers. Let us know if we can push a fix directly without a pull request, in the case we happen to have one before you do.

We recommend always consulting with upstream, chances are this is already fixed there.

Fixes are in upstream commits:
    https://github.com/davidhalter/parso/commit/6cdd47fe2b2efcb7f7b7f73a44f2d142caf39b44
    https://github.com/davidhalter/parso/commit/5430415d4463900c1780488f9cdddc5eb9814ecc

I can open a dist-git PR if upstream doesn't release these quick enough.

It appears that 0.5.0 will have these fixes.  It's already in the changelog, but isn't tagged yet or published on PyPI.  I've nudged upstream, we'll see what they say.

I've built 0.5.0 in rawhide, and confirmed it builds locally with the python3.8 copr enabled.  It should be ready now for the python3.8 mass rebuild.  Let me know if you see any other issues.
