7e818af9be Fixed bug that resulted in a false positive error when doing protocol matching where the object type (i.e. the self value) is a literal value. This addresses https://github.com/microsoft/pyright/issues/4844. 2023-03-26 21:25:38 -06:00
Eric Traut
5cf4aedbbf Did a pass over pyright source code to improve consistency of file header comments. No functional change. 2023-03-26 14:05:02 -06:00
Eric Traut
47efdfcf2c Fixed a bug that resulted in a false negative when using a type variable with an incompatible variance to specialize a generic class that uses a TypeVarTuple. This addresses https://github.com/microsoft/pyright/discussions/4841. 2023-03-25 08:33:24 -06:00
Eric Traut
95d4809d4c Fixed bug that resulted in an false positive error when using a class (and by implication, its constructor) as an input to a generic function (e.g. a decorator) that is parameterized with a ParamSpec. This addresses https://github.com/microsoft/pyright/issues/4813. 2023-03-25 06:16:45 -06:00
Eric Traut
14f458717d Added support for synthesized __slots__ symbol in dataclasses that are constructed using the slots=True argument. This addresses https://github.com/microsoft/pylance-release/issues/4147. 2023-03-24 18:09:21 -06:00
Eric Traut
8a93373e6b Added support for "naked" ClassVar used to annotate a class variable that is assigned a descriptor object but is later set through an object member access. This previously resulted in a false positive error. This addresses https://github.com/microsoft/pyright/issues/4838. 2023-03-24 11:10:59 -06:00
Eric Traut
f63069227c Fixed a bug that led to the incorrect evaluation of a symbol imported through a from a.b import c statement if a.b is a non-py.typed library, useLibraryCodeForTypes is false and c was also the name of a submodule of a.b. In this case, the evaluated type of c should be Unknown, but it was incorrectly evaluated as a module type. This addresses https://github.com/microsoft/pyright/issues/4827. 2023-03-24 07:06:08 -06:00
Eric Traut
e7668aef88 Added support for a TypeGuard function where the first argument is a TypeVar. In this case, the resulting (narrowed) type should be a conditional type that references the TypeVar. 2023-03-23 01:16:12 -06:00
Eric Traut
98e2134ea7 Reduced verbosity of CLI output for non-error conditions. 2023-03-22 18:21:31 -06:00

903fd3cee3 Added support for argument dictionary unpacking when the type of the unpacked object supports the SupportsKeysAndGetItem protocol. Previously, the object needed to be an explicit subclass of Mapping. This addresses https://github.com/microsoft/pyright/issues/4826. 2023-03-22 14:50:17 -06:00
Eric Traut
02e3e96522 Fixed bug that resulted in false positive "incompatible variance" error when covariant and contravariant type variables were used in certain combinations when defining a generic class. This addresses https://github.com/microsoft/pyright/issues/4818. 2023-03-22 14:00:58 -06:00

8d9ad7958d Fixed recent regression that caused a crash in the signature help provider. 2023-03-22 12:56:11 -06:00
Eric Traut
56c6eddc47 Fixed bug that caused diagnostic for implicit override to be reported as part of reportGeneralTypeIssue rather than `reportImplicitOverride. This addresses https://github.com/microsoft/pyright/issues/4824. 2023-03-22 12:31:26 -06:00

3ae66f24b0 Fixed a recent regression that resulted in a false positive error when a multi-part import statement was used and useLibraryCodeForTypes was disabled. This addresses https://github.com/microsoft/pyright/issues/4810. 2023-03-21 00:30:37 -06:00

54dbe9a8bd Fixed a bug that led to the incorrect type resolution for unsupported function Enum class construction. The resulting type should be Unknown, but it was evaluated as Never. This addresses https://github.com/microsoft/pyright/issues/4808. 2023-03-20 12:22:09 -06:00

252673152d Updated typeshed stubs to the latest version. 2023-03-19 11:08:17 -06:00
Eric Traut
b9e72bf147 Improved consistency of type narrowing on assignment when the target is a variable with a declared type and the assigned value is an unknown or partially-unknown type. Previously, if the assigned value was Unknown, the declared type was assumed, but if the assigned value was a union that included Unknown, the narrowed type (including the Unknown) was assumed. We now always include an Unknown in the assigned type so the reportUnknownVariableType diagnostic is reported. 2023-03-19 08:11:55 -06:00
Eric Traut
d36c524916 Fixed a couple of bugs in the type narrowing logic for class pattern matching. In particular, added better support for NoneType() patterns and cases where the subject type is a union that includes subtypes of the class pattern. This addresses https://github.com/microsoft/pyright/issues/4800. 2023-03-19 00:58:54 -06:00

7ad4a8ead5 Added support for @deprecated in an __init__ method when constructing a class. This addresses https://github.com/microsoft/pyright/issues/4456. 2023-03-18 18:30:41 -06:00
Eric Traut
575adcb29a Fixed a bug that can result in infinite recursion (and a subsequent crash) when a class instance is called and the class defines a __getattr__ method. This addresses https://github.com/microsoft/pyright/issues/4798. 2023-03-17 16:00:59 -06:00

9af43f28fe Fixed bug that resulted in a crash when user types import without a follow-on module name. This can happen in due corse of typing an import statement. This addresses https://github.com/microsoft/pyright/issues/4778. 2023-03-17 08:18:27 -06:00
Eric Traut
c7c70357dc Changed the logic in the code flow engine so it never attempts to infer a NoReturn return type for a function that lacks a return type annotation. This results in a big speed improvement for some (unannotated) code bases, but it also produces somewhat inconsistent type evaluation results because a function whose type is inferred to be NoReturn by the type checker will not be treated as such if it is called elsewhere in the program. 2023-03-17 08:08:05 -06:00
Eric Traut
0997c33577 Fixed regression that caused a crash in the presence of the illegal statement import .. This addresses https://github.com/microsoft/pyright/issues/4778. 2023-03-16 15:25:41 -06:00

c7ab8045ba Performance: Further improved perf when determining type compatibility of unions with many subtypes. This further reduces the analysis time of pydantic from 12s to 4s. This addresses https://github.com/microsoft/pyright/issues/4781. 2023-03-16 09:12:51 -06:00
Eric Traut
99c73a0f7d Performance: sped up type analyzer by 5-25% by caching types that have been converted to or from an instance. This drops the analysis time of pydantic from 17s to 12s. 2023-03-16 08:15:56 -06:00

2ca9a8af4a Fixed regression that resulted in a false positive error when using an index expression form with a class whose metaclass supplies a __getitem__ method when the expression is used as a runtime expression, as opposed to a type expression.

ce66cc21bb Fixed a bug that led to a false negative when a non-Generic class has a metaclass that defines a __getitem__ method. Such a class should not be indexable within a type annotation, but pyright was not flagging this error.
