Bug 253066 – [webkitcorepy] AutoInstall unable to install pytest-asyncio (or other packages without setup.py)

• Status: RESOLVED
• Resolution: FIXED
• Component: Tools / Tests

[Sam Sneddon [:gsnedders]]

258166@main (bug 249564) updated the AutoInstalled versions of pytest and its plugins, including pytest-asyncio. pytest-asyncio, as of 0.19, no longer includes a setup.py: it relies on the build frontend reading pyproject.toml, per PEP 517 (https://peps.python.org/pep-0517/).

However, the AutoInstall has no knowledge of PEP 517, and instead tries to run a setup.py, and falls back to just copying the whole source packages over and hoping for the best. This (unsurprisingly) doesn't work well.

Looks like pytest-asyncio includes a setup.cfg, so it's note entirely in a world with only pyproject.toml yet. We also would need to bump our setuptools version to support pyproject.toml, which I'm not against in the long term, but I think needs a tad more validation.

Fixing pytest-asyncio, however, doesn't require bumping setuptools. It just requires laying down a dummy setup.py file which picks up setup.cfg through setuptools. We don't even have to touch our invocation of setup.py, which is actually somewhat surprising.
