Sam Gross d891b2bbd1 gh-139103: Improve namedtuple scaling in free-threaded build (gh-144332) ... Add `_Py_type_getattro_stackref`, a variant of type attribute lookup that returns `_PyStackRef` instead of `PyObject*`. This allows returning deferred references in the free-threaded build, reducing reference count contention when accessing type attributes. This significantly improves scaling of namedtuple instantiation across multiple threads. * Add blurb * Rename PyObject_GetAttrStackRef to _PyObject_GetAttrStackRef * Apply suggestion from @vstinner Co-authored-by: Victor Stinner <vstinner@python.org> * Apply suggestion from @vstinner Co-authored-by: Victor Stinner <vstinner@python.org> * format * Update Include/internal/pycore_function.h Co-authored-by: Victor Stinner <vstinner@python.org> --------- Co-authored-by: Victor Stinner <vstinner@python.org>		2026-02-06 09:43:05 -05:00
