xeger: avoid deprecated sre_parse module in python-3.11+

[slyon]

The undocumented sre_parse module got deprecated in Python 3.11 which leads to build/test failures on Linux distributions making use of this version, e.g. Ubuntu 23.04.

See bpo-47152: python/cpython#91308

Thanks for this fix! Please add Python 3.11 to tox.ini to make sure we have test coverage for this.

[slyon]

Hmm.. looks like we need some more work on the CI: ERROR: InterpreterNotFound: python3.11

Do you have any hints what needs to be done here? Do we need to switch to a newer CI runner, supporting python3.11?

[bjmc]

Sounds like it. Either a newer CI runner, or get Py3.11 added to this one. This project uses https://github.com/mikicz/docker-tox-base as the Docker image for CI runs - you could add (or request) support for 3.11 there.

I'm busy now, but I can take a look at it this weekend.

There's also an unrelated mypy failure around typing, so that needs to be fixed as well.

[slyon]

I silenced the two mypy errors, as those seem to be false positives to me.

It would be great if you could have a look into the docker-tox-base CI image, to enable py311, thanks!
I already applied this patch in Ubuntu (slightly modified, to match downstream sources): https://launchpad.net/ubuntu/+source/python-rstr/2.2.6-3ubuntu1

This isn't rstr v2.2.6 any more - this should be at least 3.2.0 and it will probably be 3.2.1 🙂

[slyon]

Right, that's why I backported the patch in Ubuntu. And we'll move ahead to a more recent upstream version, once the Debian mantainer decides to do so: https://tracker.debian.org/pkg/python-rstr

Sorry for the delay. Thanks for your contribution @slyon! Would you like to be listed in AUTHORS?

Thanks for getting it landed. No need to give credit in AUTHORS for this tiny "drive-by fix".
