bpo-40137: Optimize _PyType_GetModuleByDef() loop - #25505
Merged
Conversation
PyType_Ready() now ensures that a type MRO cannot be empty. _PyType_GetModuleByDef() no longer checks "i < PyTuple_GET_SIZE(mro)" at the first loop iteration to optimize the most common case, when the argument is the defining class.
