I cannot find "PyType_SUPPORTS_WEAKREFS" in the source code of top 5000 PyPI projects. |
Convert the PyType_SUPPORTS_WEAKREFS() macro to a regular function. It no longer access the PyTypeObject.tp_weaklistoffset member directly. Add _PyType_SUPPORTS_WEAKREFS() static inline functions, used internally by Python for best performances.

This change has no impact on performance (Python internals continue accessing directly the PyTypeObject) and no impact on the API (the function remains available in the public C API). |
