We do the following: * add a per-interpreter XID registry (PyInterpreterState.xidregistry) * put heap types there (keep static types in _PyRuntimeState.xidregistry) * clear the registries during interpreter/runtime finalization * avoid duplicate entries in the registry (when _PyCrossInterpreterData_RegisterClass() is called more than once for a type) * use Py_TYPE() instead of PyObject_Type() in _PyCrossInterpreterData_Lookup() The per-interpreter registry helps preserve isolation between interpreters. This is important when heap types are registered, which is something we haven't been doing yet but I will likely do soon.
The Python C API ================ The C API is divided into these sections: 1. ``Include/``: Limited API 2. ``Include/cpython/``: CPython implementation details 3. ``Include/cpython/``, names with the ``PyUnstable_`` prefix: API that can change between minor releases 4. ``Include/internal/``, and any name with ``_`` prefix: The internal API Information on changing the C API is available `in the developer guide`_ .. _in the developer guide: https://devguide.python.org/c-api/
