409df8ff72
Fixed bug that results in false positive when evaluating the call to a generic function that involves a type variable used in both a covariant and contravariant (or invariant) position and both literal and non-literal types are involved. This addresses part of #6207. (#8049) 2024-06-02 14:19:13 -07:00

ecc4ebb12a Fixed bug that results in a confusing error message when stub generation fails. This addresses #8044. 2024-06-01 11:29:00 -07:00

8a2857876b Renamed references to "list comprehension" to "comprehension" in various places for clarity. Comprehensions can be used in lists, dicts, sets or none of the above (in which case it's interpreted as a generator). 2024-05-31 17:57:40 -07:00

Changed the tuple inference behavior to retain literals (as it did prior to 1.1.365) when a tuple expression is used within a generator expression. This addresses #8035. (#8036) 2024-05-31 17:37:06 -07:00

e69974cee0 Fixed bug that results in a false positive error under certain circumstances involving a call to a higher-order generic function with another function that involves a class with a contravariant type variable. This addresses #7212. 2024-05-31 13:44:51 -07:00

Changed behavior of constructor call evaluation when __new__ evaluation results in type evaluation errors. Previously, pyright skipped the __init__ evaluation in this case. It now proceeds to evaluate __init__, potentially generating redundant errors. This addresses #8026. (#8029) 2024-05-30 12:49:11 -07:00

Changed the TypeVar scoping behavior for TypeVars that appear only within a Callable subtype within a function's declared return type. Previously, pyright scoped these TypeVars to the Callable rather than the function. This was due to issue #4285. I'm reversing this decision because it's not spec-compliant, creates a bunch of unnecessary complexity, and results in buggy behavior. This addresses #7722. (#7918) 2024-05-14 15:53:06 -07:00

Added special-case handling for __init_subclass__ checks for classes that have ABCMeta as a metaclass. Previously, these were exempted from __init_subclass__ because ABCMeta has a custom __new__ method, but we know that this metaclass calls through to type.__new__ which calls __init_subclass__.

Fixed a bug that led to poor performance (effectively a hang) if an unannotated function is called through many (greater than 8) call expressions within a loop using different literal-value arguments each time. This addresses #7791. (#7792) 2024-04-27 15:45:29 -07:00

Issue7779 (#7781) 
* Changed `TypeIs` to use the same logic as `isinstance` type narrowing logic for consistency. This addresses #7767, #7760, and #7647.

* Fixed bug that results in a false positive error when a `yield` statement is used within a lambda following a function. This addresses #7779.

Fixed bug that resulted in incorrect bidirectional type inference when calling a constructor for a generic class that defines no __new__ or __init__ method. This addresses #7764. (#7776) 2024-04-25 21:10:10 -07:00
Eric Traut
c640765de5 Changed logic that synthesizes the constructor methods for a NamedTuple subclass (using the class syntax) so the __new__ method contains parameters based on field names and the __init__ method contains a general *args: Any, **kwargs: Any parameter signature. Previously, this was swapped, but the new way is more faithful to the runtime. This addresses #7769. 2024-04-25 20:30:30 -07:00

Fixed bug in protocol matching that results in a false positive when the subject object is a dataclass that contains a callable. It should be considered an instance member in this case, so it should not be bound to the class. This addresses #7735. (#7749) 2024-04-22 20:47:48 -07:00

Changed behavior to no longer exempt unguarded access to not-required TypedDict member within a try or with block. Previously, such errors were exempt, but this is inconsistent with other type checks in pyright which eschew the practice of using exception handling for normal code flow. This addresses #7714.

f22576f0f8 Moved check for invalid use of class-scoped TypeVar within a self annotation in __init__.

Added a check for the case where a frozen dataclass overrides a field from its parent class but doesn't provide a default value (where its parent does). This can result in a type violation if the parent's default value is not compatible with the child's (covariant) field type. This addresses #7702. (#7704) 2024-04-14 11:39:26 -07:00

Changed the behavior when invoking constructor for type[T] where T is a TypeVar with no explicit upper bound (and therefore has an implicit upper bound of object).
