There was a problem hiding this comment.
This looks good to me, thank you!
Clearly when we add full field_specifiers support, we will probably replace/remove this simple boolean flag. But this improves the current behavior, and doesn't make the future changes more difficult.
@sharkdp are you okay with this temporary fix?

Going to go ahead and merge this, it's a small PR, there's nothing here that we can't easily change again. Thank you for the fix! |
Yes, of course. Thank you for this contribution! |

This commit corrects the type checker's behavior when handling
dataclass_transformdecorators that don't explicitly specifyfield_specifiers. According to PEP 681 (Data Class Transforms), whenfield_specifiersis not provided, it defaults to an empty tuple, meaning no field specifiers are supported anddataclasses.field/dataclasses.Fieldcalls should be ignored.Fixes astral-sh/ty#980
