[RFC] Remove ClassType <: SelfType subtyping rule by fangyi-zhou · Pull Request #2658 · facebook/pyrefly

Summary

NOTE: I want to get some early reviews for this subtyping change before I spend more time investigating type errors in the wild. If this is a change that has a path to lead to acceptable, I'll work towards that.

This diff proposes the removal of the subtyping rule of ClassType <: SelfType. The observations leading to this change are as follows:

Current rule is unsound and not spec-compliant
Ideally we should treat Self as a bounded type var, but our support is limited
The rule seems to be used at very specific places, so we can hand-apply this rule when necessary

The implementation follows these ideas, I created a helper function to convert all Self types into regular class types, and applies the transformation at the following places:

Handling decorated functions (decoratee's type is converted)
Overload consistency checks (method types are converted)
Converting a constructor into a callable

To avoid cycles, we skip overload consistency checks on the self or cls parameter, since subtyping checks will trigger variance checks, which in turn causes cycles. To compensate, we add some inheritance checks on self and cls to ensure we don't accept bad receiver types.

Test Plan

Conformance test cases, regression test cases, and checking for errors in the wild

When applying a decorator to a method, the method's `self` parameter has type `Self@C` (SelfType), but decorators expect `C` (ClassType). This caused false positive bad-argument-type errors for decorators like `cache_on_self(fn: Callable[[C], int])`. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

The overload consistency check triggered variance computation on the defining class, which needed class fields (including the __init__ being resolved), causing a cycle that resolved to Any(Implicit). Fix by skipping the self/cls parameter in the consistency check input signature comparison, and converting SelfType to ClassType in constructor return type paths. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Comparing return types that reference the defining class (e.g. `partial[...]` in `__new__`) triggers variance computation, which needs class fields including the overloaded method itself, causing a cycle that resolves types to Any. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Previously `type_of` collapsed `SelfType(cls)` into `ClassDef(cls)`, losing the Self information. Now it returns `Type(SelfType(cls))`, so `type(self)()` correctly produces `Self@C` instead of `C`. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

The overload consistency check skips the self/cls parameter to avoid variance computation cycles. This adds explicit validation that the self type in __init__ is either the defining class or a superclass, catching bad annotations like `self: A` on an unrelated class. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Add validation that __init__ self type must be the defining class or a superclass, and __new__ cls type must be type[X] where X is the defining class or a superclass. This catches bad annotations that were previously only caught by the overload consistency check (which now skips self/cls). Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

…tion Restore the overload return type consistency check for class methods (reverting 18a8006). The variance cycle for functools.partial is now documented as a known bug instead. Also fix __new__ cls annotation validation to accept type[TypeVar] (the standard __new__ pattern). Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
