* Rename typing._collect_parameters (#118900)Jelle Zijlstra2024-05-101-7/+17
| | | | | | | | | | | Unfortunately, released versions of typing_extensions monkeypatch this function without the extra parameter, which makes it so things break badly if current main is used with typing_extensions. Fortunately, the monkeypatching is not needed on Python 3.13, because CPython now implements PEP 696. By renaming the function, we prevent the monkeypatch from breaking typing.py internals. We keep the old name (raising a DeprecationWarning) to help other external users who call it.

* gh-113320: Reduce the number of dangerous `getattr()` calls when ↵Alex Waygood2024-01-051-18/+28
| | | | | | | constructing protocol classes (#113401) - Only attempt to figure out whether protocol members are "method members" or not if the class is marked as a runtime protocol. This information is irrelevant for non-runtime protocols; we can safely skip the risky introspection for them. - Only do the risky getattr() calls in one place (the runtime_checkable class decorator), rather than in three places (_ProtocolMeta.__init__, _ProtocolMeta.__instancecheck__ and _ProtocolMeta.__subclasscheck__). This reduces the number of locations in typing.py where the risky introspection could go wrong. - For runtime protocols, if determining whether a protocol member is callable or not fails, give a better error message. I think it's reasonable for us to reject runtime protocols that have members which raise strange exceptions when you try to access them. PEP-544 clearly states that all protocol member must be callable for issubclass() calls against the protocol to be valid -- and if a member raises when we try to access it, there's no way for us to figure out whether it's a callable member or not!
