Dev Call: 1 June 2023

Antonio, Florian, Matti, Tim, Stepan, Petr, Du Toit

There is an issue concerning the quickstart guide where installation doesn't work: #434
The same person also has issues with pyproject.toml since we are adding absolute paths to the list of sources (#435). Simon and Florian already discussed how to solve hat and we will (for now) just copy files to the HPy extension to avoid absolute paths.
HPy can't probably drop the setuptools support but we could add meson support
HPy itself could move to meson

Florian did a little fix (missing source file) and create a new release candidate.
Florian updated all project in the hpyproject GitHub org to be compatible with 0.9.
When should we do the official 0.9 release? Let's wait until PyPy and GraalPy are ready.

Łukasz specifically asked if one HPy person would be interested in a sponsorship
Possible HPy-related topic to work on: The sponsored person could work on the CPython impl of HPy and implement pointer tagging (int boxing) and maybe show some benefit.
We are thinking about a co-locating an HPy sprint since attendees of the CPython core dev sprint should work on CPython topics. GraalPy team has some connections to Brno University and could probably organize some room for the sprint.
PROPOSAL: We could do an HPy sprint starting before the CPython core dev sprint and have 1-2 days overlap with the CPython core dev sprint.
Antonio is willing to go to the CPython core dev sprint but yet doesn't know for sure.
Florian, Tim, and Stepan would also have time.
Antonio will ask Brett Cannon if he would sponsor Antonio. Then one more person could go with Łukasz.
Petr says that it would basically be possible that Łukasz sponsors more that one person. However, those persons shouldn't take all of Łukasz' time.
If we need funding from the PSF, we should fill out the form now; otherwise, notify Petr a week before if you attend.
The sprint will be in the Red Hat office. So, limited space and restricted access. We can't just happend to be there.
Petr plans to have a C API summit day at the CPython core dev sprint. Most likely in the beginning of the sprint (first/second day).

Du Toit is finishing up his Master's thesis and will upload it to Discord to get feedback.
Since the official Python language blog post is out, Florian will prepare an HPy blog post as well.
