Added support for type narrowing of a class pattern when the specified class is type() or a subtype thereof and the subject contains a type[X] whose metaclass potentially matches the pattern. This addresses https://github.com/microsoft/pyright/issues/5573. (#5576)

12e9c31187 Fixed a theoretical bug in the code that detects unique type signatures. It wasn't correctly handling constructor methods. 2023-07-25 11:03:46 -07:00

e8250ba18f Fixed a bug that resulted in the incorrect inferred variance for a type variable used within a frozen dataclass. This addresses #5568. 2023-07-23 16:49:25 -07:00

Added support within the constraint solver for higher-order functions that accept a callable parameterized with a ParamSpec where the passed callable is generic. This addresses #5495. (#5567)

Modified the heuristics used for narrowing on assignment when the assigned type contains an Any. If the target's declared type does not contain Any, the assignment shouldn't produce an Any within the resulting type. This addresses #5413. (#5566)

Fixed a bug that led to a false positive when a constrained type variable was used as a type argument in an annotation for an argument passed to a method that's bound to the same type variable. This addresses #5556. (#5557)

Fixed an inconsistency in reporting of unbound variables when the variable is captured by an inner scope. The new behavior correctly identifies unbound (or potentially unbound) variables in cases where the captured variable is narrowed. This happens when there are no assignments to the variable after it is captured. This addresses #5548. (#5551) 
Fixed a bug in type narrowing for captured variables. Captured variables that are modified in other scopes using a `nonlocal` or `global` binding should be ineligible for type narrowing.

Fixed an issue in type evaluation of call expressions where the callable subexpression evaluates to a union, and the callable subtypes have different signatures. Pyright was previously caching the types from the first subtype, so it didn't re-evaluate using the second subtype (which may require bidirectional type inference). This addresses #5428. (#5547)

455830ed42
Improved error messages for situations where a call expression targets an overloaded function or method and there are no matches. Added some heuristics to pick the "best" overload function for the error message. Previously, pyright used the last overload, but this sometimes led to confusing errors. This addresses #5525.

6a25a7bf0b Removed the requirement that a TypedDict be marked @final for it to be considered for type narrowing as part of a S in D type guard pattern. This requirement wasn't sound because TypedDict is a structural type (i.e. a protocol), so @final doesn't have any real meaning. 2023-07-17 08:01:52 -07:00
