patch 9.0.2036: if_python: rework python3.12 build dependency Commit: https://github.com/vim/vim/commit/396058acd0cc66e5071d052e03d2067b134952af Author: Yee Cheng Chin <ychin.git@gmail.com> Date: Tue Oct 17 10:38:11 2023 +0200 patch 9.0.2036: if_python: rework python3.12 build dependency Problem: if_python: rework python3.12 build dependency (after 9.0.1996) Solution: use PyTuple_Size instead of inlining the Py_SIZE into the Vim code base Use a simpler fix for Python 3.12 build issues Python 3.12 introduced link dependencies to their `Py_SIZE()` inline function, which #13290 fixed by copying the inline function to Vim's Python binding code. This works but it's fragile, as a future update may change the implementation of `Py_SIZE` and there is no way for us to know. The reason we need `Py_SIZE` to begin with is that we use `PyTuple_GET_SIZE()` which calls that. Just fix it by mapping that to (confusingly similarly named) `PyTuple_Size()`, which we already do in the stable ABI implementation. There's a minor performance cost in that it's not inlined and it does error checking but that's fine as we only call this function rarely (in an error handler). related: #13290 closes: #13359 Signed-off-by: Christian Brabandt <cb@256bit.org> Co-authored-by: Yee Cheng Chin <ychin.git@gmail.com>
