The attached script works perfectly fine under Python 3.8, but it crashes in 3.9/3.10.
$ ./py38/python typing_fail.py (3.8.5+)
{'a': <class 'int'>, 'b': <class 'int'>}
$ ./py39/python typing_fail.py (3.9.0rc1+)
[SNIP]
TypeError: 'NoneType' object is not subscriptable
$ ./cpython/python typing_fail.py (3.10.0a0)
[SNIP]
TypeError: 'NoneType' object is not subscriptable

This looks like a problem with the __globals__ of the NamedTuple.__new__ |

Not nice to snip the traceback. |

Commit 3ff51d425ecd98b7ba5a12ca9f77eda73fbf9f53 set the __builtins__ to None in namedtuple's creation, but the problem is that it is causing harm when the point came to the point of getting type hints on typing.NamedTuple.__new__ (we had a test about it), I'm changing that test (in the PR 20434) to work directly with the namedtuple itself instead of __new__ (since the annotations get proxied). |
