* gh-129701: Fix a data race in `intern_common` in the free threaded build * Use a mutex to avoid potentially returning a non-immortalized string, because immortalization happens after the insertion into the interned dict. * Use `Py_DECREF()` calls instead of `Py_SET_REFCNT(s, Py_REFCNT(s) - 2)` for thread-safety. This code path isn't performance sensistive, so just use `Py_DECREF()` unconditionally for simplicity.
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/
