90f8653d03 Added a new check for a TypeGuard or StrictTypeGuard function that does not have at least one input parameter. This addresses https://github.com/microsoft/pyright/issues/4448. 2023-01-12 18:05:41 -08:00

bfcf41c227 Fixed bug that led to a false positive when using method-scoped type variables in a type annotation for a cls parameter in a classmethod. This addresses https://github.com/microsoft/pyright/issues/4447. 2023-01-12 12:30:44 -08:00

638eee8d94 Fixed a bug that resulted in an infinite loop when tuple addition was used within a loop construct. This addresses https://github.com/microsoft/pyright/issues/4424. 2023-01-11 19:46:45 -08:00

fa18230733 Fixed bug in dataclass_transform logic for frozen_default. If the frozen_default is set to True, it wasn't possible to override it with False explicitly. This addresses https://github.com/microsoft/pyright/issues/4444. 2023-01-11 14:58:49 -08:00

8de57a8e3e Fixed a bug in the truthy/falsy type guard logic when using self (or another bound TypeVar) where the bound class implements a __bool__ method. This addresses https://github.com/microsoft/pyright/issues/4439. 2023-01-11 09:59:33 -08:00

46bf2fe11f Fixed a bug that causes incorrect interpretation of a large integer literal value — one that doesn't fit within a 53-bit mantissa. This addresses https://github.com/microsoft/pyright/issues/4435. 2023-01-10 21:59:13 -08:00
Eric Traut
336c61ad5e Fixed a bug that resulted in incorrect type evaluation for a callable attribute within a TypedDict or dataclass. If the attribute has no type annotation, it should be treated as a class variable, not an instance variable. This addresses https://github.com/microsoft/pyright/issues/4432. 2023-01-10 21:43:24 -08:00

8388cb0a1d Add a bit more logging to try to better understand an assert_never that is appearing in the telemetry. 2023-01-10 12:54:49 -08:00
Eric Traut
09ce380899 Removed unnecessary function deleteTypeCacheEntry. Since type cache entries are always overwritten in these code paths, there's no need to explicitly delete them. 2023-01-08 18:40:47 -08:00
Eric Traut
9d71447609 Fixed a bug that resulted in a false positive error when a generic class used a contravariant type variable and defined a __new__ method that uses cls: type[Self] as a parameter. This addresses https://github.com/microsoft/pyright/issues/4421. 2023-01-08 14:31:31 -08:00

0caf09c511 Fixed a bug that resulted in incorrect isinstance type narrowing in certain cases when found within a loop construct. This addresses https://github.com/microsoft/pyright/issues/4419. 2023-01-07 18:55:42 -08:00
Eric Traut
4721364395 Fixed a bug in PEP 696 (TypeVar defaults) logic that resulted in a false positive error when a Self type was used within a generic method that also used a TypeVar with a default type. This addresses https://github.com/microsoft/pyright/issues/4418. 2023-01-07 17:59:47 -08:00
Eric Traut
c7ed87e18b Fixed a bug that led to a false negative when comparing a function without a *args to a callable type with a *args. This addresses https://github.com/microsoft/pyright/issues/4414. 2023-01-06 21:49:18 -07:00
Eric Traut
e8dc353f6d Fixed a bug that resulted in an incorrect type evaluation when calling a constructor on a class that uses new PEP 696 TypeVar defaults and provides an __init__ but no __new__. This addresses https://github.com/microsoft/pyright/issues/4417. 2023-01-06 20:04:05 -07:00
Eric Traut
a5b3ab2a37 Fixed a bug that resulted in a false positive error in certain cases when using PEP 695 type parameter syntax. 2023-01-06 18:41:47 -07:00
Eric Traut
b32eaa35f7 Fixed a recent regression that led to a false positive in certain cases when a call to a generic function was made within a loop. This addresses https://github.com/microsoft/pyright/issues/4415. 2023-01-06 13:00:17 -07:00
Eric Traut
b3f57edde8 Fixed a bug that resulted in a false positive when using heavily-nested call expressions that target overloads. The speculative type cache was not storing information about whether the type evaluation resulted in errors, so incorrect overloads were being chosen in the cached path. This addresses https://github.com/microsoft/pyright/issues/4403. 2023-01-05 11:03:47 -07:00

Eric Traut
9e6a22e233 Added error handling for PEP 696 to check for the case where a TypeVarLike without a default type is found after a TypeVarLike with a default type in a parameter list. 2022-12-27 16:28:57 -07:00
