GH-120097: Make FrameLocalsProxy a mapping by markshannon · Pull Request #120101 · python/cpython

markshannon · 2024-06-05T09:35:00Z

Issue: FrameLocalsProxy is not a mapping #120097

Lib/_collections_abc.py

sobolevn · 2024-06-05T10:06:02Z

Lib/test/test_frame.py

            copy.deepcopy(d)

+    def test_is_mapping(self):
+        x = 1


Why do you need x? To fill f_locals? In this case I propose to use a inner function. Or maybe two: with and without locals.

The contents are irrelevant, but we want something just to make sure we are testing the right thing.
Without x = 1, the locals would just be {} and it would be too easy to mistakenly test the wrong mapping.

Is the test failure related?
