* bpo-42073: allow classmethod to wrap other classmethod-like descriptors ↵Miss Islington (bot)2021-07-151-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | (GH-27115) (GH-27162) Patch by Erik Welch. bpo-19072 (GH-8405) allows `classmethod` to wrap other descriptors, but this does not work when the wrapped descriptor mimics classmethod. The current PR fixes this. In Python 3.8 and before, one could create a callable descriptor such that this works as expected (see Lib/test/test_decorators.py for examples): ```python class A: @myclassmethod def f1(cls): return cls @classmethod @myclassmethod def f2(cls): return cls ``` In Python 3.8 and before, `A.f2()` return `A`. Currently in Python 3.9, it returns `type(A)`. This PR make `A.f2()` return `A` again. As of GH-8405, classmethod calls `obj.__get__(type)` if `obj` has `__get__`. This allows one to chain `@classmethod` and `@property` together. When using classmethod-like descriptors, it's the second argument to `__get__`--the owner or the type--that is important, but this argument is currently missing. Since it is None, the "owner" argument is assumed to be the type of the first argument, which, in this case, is wrong (we want `A`, not `type(A)`). This PR updates classmethod to call `obj.__get__(type, type)` if `obj` has `__get__`.
