This partially reverts #137047, keeping the tests for GC collectability of the original class that dataclass adds `__slots__` to. The reference leaks solved there are instead solved by having the `__dict__` & `__weakref__` descriptors not tied to (and referencing) their class. Instead, they're shared between all classes that need them (within an interpreter). The `__objclass__` ol the descriptors is set to `object`, since these descriptors work with *any* object. (The appropriate checks were already made in the get/set code, so the `__objclass__` check was redundant.) The repr of these descriptors (and any others whose `__objclass__` is `object`) now doesn't mention the objclass. This change required adjustment of introspection code that checks `__objclass__` to determine an object's “own” (i.e. not inherited) `__dict__`. Third-party code that does similar introspection of the internals will also need adjusting. Co-authored-by: Jelle Zijlstra <jelle.zijlstra@gmail.com>
This directory contains a number of Python programs that are useful
while building or extending Python.
