Serhiy Storchaka added the comment:
There is one test
(ClassPropertiesAndMethods.test_mutable_bases_with_failing_mro in test_descr)
that crashes with the code from issue551412 because _PyType_Lookup() is
recursive called from PyType_Ready(). Is this the reason? My patch prevents
recursive calls.
Here is minimal example (for Python 3):
class M(type):
def mro(self):
hasattr(self, 'foo')
return type.mro(self)
class C(metaclass=M):
pass
When class C is created, C.mro() is called while C still is not ready.
Resolving an attribute calls _PyType_Lookup() which calls PyType_Ready() which
calls mro() etc.
