0.30 release #6126
Description
Activity
I'm not sure what your plans are @davidhewitt, but it might be nice to do a quick 0.30 release without too much delay, to unblock rust-numpy abi3t support: PyO3/rust-numpy#556 (comment)
Agreed, my intent is to test #6321, decide whether it's trivial to ship in 0.30 (or wait to 0.31, sorry for the delay either way @lucascolley), and then prep the release.
... have just recently been bogged down in the pile of fixes which ended up being 0.29.3.
Reacted by Lucas ColleyAgreed, my intent is to test #6321, decide whether it's trivial to ship in 0.30 (or wait to 0.31, sorry for the delay either way @lucascolley), and then prep the release.
Note that #6321 may not contain the latest tested version of the Meson code required to build PyO3 (I haven't updated it and I don't know whether @lucascolley did). The latest is in mesonbuild/meson-python#874 and applies to PyO3 0.23.2. I haven't looked at the diff between 0.23.2 and 0.23.3 to determine if any update is required.
It would be great if someone that better understand the PyO3 build would look at this Meson code, and it would be even better if testing of it could be integrated in the PyO3 project. On the other hand, Meson support for Rust is not very mature and integrating the Meson build system upstream may run into some sharp edges.

Yeah, I like the idea of somehow running the full PyO3 test suite using meson instead of build.rs files. Anything else is likely to bitrot.
So definitely not trivial to merge as-is.
While the 0.29 release is not yet out the door, there have been a few topics which have been notable but not quite ready to ship in 0.29. I wanted to list these here now so that we can avoid forgetting these as we work towards 0.30.
