## Summary Infer a type of `Self` for unannotated `self` parameters in methods of classes. part of https://github.com/astral-sh/ty/issues/159 closes https://github.com/astral-sh/ty/issues/1081 ## Conformance tests changes ```diff +enums_member_values.py:85:9: error[invalid-assignment] Object of type `int` is not assignable to attribute `_value_` of type `str` ``` A true positive ✔️ ```diff -generics_self_advanced.py:35:9: error[type-assertion-failure] Argument does not have asserted type `Self@method2` -generics_self_basic.py:14:9: error[type-assertion-failure] Argument does not have asserted type `Self@set_scale ``` Two false positives going away ✔️ ```diff +generics_syntax_infer_variance.py:82:9: error[invalid-assignment] Cannot assign to final attribute `x` on type `Self@__init__` ``` This looks like a true positive to me, even if it's not marked with `# E` ✔️ ```diff +protocols_explicit.py:56:9: error[invalid-assignment] Object of type `tuple[int, int, str]` is not assignable to attribute `rgb` of type `tuple[int, int, int]` ``` True positive ✔️ ``` +protocols_explicit.py:85:9: error[invalid-attribute-access] Cannot assign to ClassVar `cm1` from an instance of type `Self@__init__` ``` This looks like a true positive to me, even if it's not marked with `# E`. But this is consistent with our understanding of `ClassVar`, I think. ✔️ ```py +qualifiers_final_annotation.py:52:9: error[invalid-assignment] Cannot assign to final attribute `ID4` on type `Self@__init__` +qualifiers_final_annotation.py:65:9: error[invalid-assignment] Cannot assign to final attribute `ID7` on type `Self@method1` ``` New true positives ✔️ ```py +qualifiers_final_annotation.py:52:9: error[invalid-assignment] Cannot assign to final attribute `ID4` on type `Self@__init__` +qualifiers_final_annotation.py:57:13: error[invalid-assignment] Cannot assign to final attribute `ID6` on type `Self@__init__` +qualifiers_final_annotation.py:59:13: error[invalid-assignment] Cannot assign to final attribute `ID6` on type `Self@__init__` ``` This is a new false positive, but that's a pre-existing issue on main (if you annotate with `Self`): https://play.ty.dev/3ee1c56d-7e13-43bb-811a-7a81e236e6ab ❌ => reported as https://github.com/astral-sh/ty/issues/1409 ## Ecosystem * There are 5931 new `unresolved-attribute` and 3292 new `possibly-missing-attribute` attribute errors, way too many to look at all of them. I randomly sampled 15 of these errors and found: * 13 instances where there was simply no such attribute that we could plausibly see. Sometimes [I didn't find it anywhere]( |
