Bug Fixes:

  • Changed the fallback type from Unbound to Unknown for the case where pyright determines that a symbol requires code flow analysis but the execution scope exceeds the cyclomatic complexity threshold.
  • Fixed a bug that results in a false positive "recursive type definition" error under certain circumstances when the number of declarations for a symbol exceeds the internal threshold of 16.
  • Fixed a bug that results in incorrect handling of a "bare" ClassVar annotation either with or without an assignment.
  • [From pylance] The default python version was not being picked up from the environment.
  • Fixed bug that results in false negative when a parameter is used within a type expression and the parameter's type is a TypeVar or Self.
  • Fixed bug that results in a false negative when two import statements shadow the same symbol and an attribute is accessed between the two import statements.
  • Fixed bug that results in a crash (due to infinite recursion) if an enum class uses a reference to an enum member in an annotation for that same enum member.
  • Fixed a bug that results in incorrect type evaluation when passing a function with a callable parameter that uses Concatenate plus ParamSpec to a function that accepts a callable with just a ParamSpec.
  • Added missing check for illegal use of Final within a TypedDict or NamedTuple definition.
  • Tweaked the algorithm for computing the complexity of a code flow graph to accommodate slightly larger graphs before giving up.

Enhancements:

  • Updated typeshed stubs to the latest version.
  • Added @override enforcement for an overloaded method that has no implementation.
  • Added code to conform with the new checks mandated in the typing spec for @final and @override applied to an overload.
  • Extended type narrowing for the X is L and X is not L type guard pattern. Previously, narrowing was performed only when L was an enum or bool literal. Narrowing is also now applied for other literal types but only in the positive (if) direction.
  • Modified the overload call evaluation logic to conform with the new proposed type specification rules regarding *args parameters.
  • Added support for argument type expansion of bool, enums, and tuples of fixed length when evaluating overloads. This behavior is mandated by the new draft typing spec update.
