> But did we actually audit the code to make sure nothing relies on the GIL? Otherwise we're just asking for trouble. Since a big chuck of PyArrow relies on Cython, that means that a lot of the free-threading heavy-lifting will be performed by Cython. Regarding the C/C++ code, I had a look around the codebase, trying to manually search for global state, but I didn't find any instances that might create problems. I also talked a bit with @jorisvandenbossche about that during a call, and adding threading-related tests was something he wanted to do as well. As a note, being agressive with declaring support for free-threading is probably the way to go, since bugs will always be there, and they will be much harder to surface if widely-used packages do no declare support. Remember that the GIL is enabled for the whole process, even if just one package hasn't declared support. -- This is an automated message from the Apache Git Service.
