Shunsuke Shibayama 9dd666d677 [ty] fix global symbol lookup from eager scopes (#21317) ... ## Summary cf. https://github.com/astral-sh/ruff/pull/20962 In the following code, `foo` in the comprehension was not reported as unresolved: ```python # error: [unresolved-reference] "Name `foo` used when not defined" foo foo = [ # no error! # revealed: Divergent reveal_type(x) for _ in () for x in [foo] ] baz = [ # error: [unresolved-reference] "Name `baz` used when not defined" # revealed: Unknown reveal_type(x) for _ in () for x in [baz] ] ``` In fact, this is a more serious bug than it looks: for `foo`, [`explicit_global_symbol` is called](6cc3393ccd/crates/ty_python_semantic/src/types/infer/builder.rs (L8052)), causing a symbol that should actually be `Undefined` to be reported as being of type `Divergent`. This PR fixes this bug. As a result, the code in `mdtest/regression/pr_20962_comprehension_panics.md` no longer panics. ## Test Plan `corpus\cyclic_symbol_in_comprehension.py` is added. New tests are added in `mdtest/comprehensions/basic.md`. --------- Co-authored-by: Micha Reiser <micha@reiser.io> Co-authored-by: Carl Meyer <carl@astral.sh>		2025-11-12 10:15:51 -08:00
