[3.7] bpo-38395: Fix ownership in weakref.proxy methods (GH-16632) (GH-16663)

2019-10-11T20:28:49+00:00

The implementation of weakref.proxy's methods call back into the Python
API using a borrowed references of the weakly referenced object
(acquired via PyWeakref_GET_OBJECT). This API call may delete the last
reference to the object (either directly or via GC), leaving a dangling
pointer, which can be subsequently dereferenced.

To fix this, claim a temporary ownership of the referenced object when
calling the appropriate method. Some functions because at the moment they
do not need to access the borrowed referent, but to protect against
future changes to these functions, ownership need to be fixed in
all potentially affected methods..

bpo-38013: make async_generator_athrow object tolerant to throwing exceptions (GH-16070)

2019-09-17T13:19:25+00:00

Even when the helper is not started yet.

This behavior follows conventional generator one.
There is no reason for `async_generator_athrow` to handle `gen.throw()` differently.
