bpo-46417: Fix race condition on setting type bases (GH-30788) (GH-30789)

2022-01-22T14:28:36+00:00

Fix a race condition on setting a type __bases__ attribute: the
internal function add_subclass() now gets the
PyTypeObject.tp_subclasses member after calling PyWeakref_NewRef()
which can trigger a garbage collection which can indirectly modify
PyTypeObject.tp_subclasses.

bpo-46442: improve and rename testExceptionCleanupNames (GH-30758)

2022-01-22T07:34:29+00:00

The test tested that explicitly deleting the local variable bound to the exception
did not cause problems, but it did not test what it actually claimed to test, i.e.
that the variable is deleted automatically.
