Sourced from pyright's releases.

Published 1.1.343

Bug Fixes:

• Fixed bug that resulted in crash when using language server APIs in certain circumstances.
• Fixed bug that resulted in incorrect type evaluation of a variable within a loop under certain conditions.
• Fixed a bug in the function type assignment logic that leads to a false positive under certain circumstances involving a ParamSpec in an overload with a callback that includes a positional-only parameter separator.
• Fixed a bug that leads to a false negative when Self is used within a class definition statement. PEP 637 explicitly rejects this usage of Self.
• Fixed a bug that leads to a false negative when Self is used within a metaclass. PEP 637 explicitly rejects this usage of Self.

Enhancements:

• Eliminated some unnecessary work when determining the effective type of a symbol that doesn't have a declared type. When evaluated in the context of a particular usage, it's unnecessary to evaluate any assignments within the same execution scope.
• Add error checking for illegal use of unary, binary, or ternary operators within a type annotation.
• Added detection of invalid keyword arguments in TypedDict class definition when using the normal class syntax.
• Added detection of a call to TypedDict alternative syntax form that assigns the resulting class to a variable whose name doesn't match the name specified in the TypedDict call.
• Added check for the use of a TypedDict class in an isinstance or issubclass call. These generate a runtime exception.

Published 1.1.342

Bug Fixes:

• Fixed @deprecated functionality that was broken by a recent change to the typeshed stubs (which replaced a function with a class).
• Fixed bug that results in a false positive error under certain circumstances when calling an inner function that uses a ParamSpec defined scoped to an outer function.
• Fixed a bug in the --verifytypes CLI feature that resulted in a false negative when docstrings are missing from a class or function that is defined in a private module but re-exported from a public module.
• Fixed a bug that led to a combinatoric explosion and an infinite loop in certain edge cases involving a class with an untyped constructor and methods that return recursive types.
• Fixed a bug that led to false negative errors when doing protocol matching with a method that uses Self in its signature.
• Increased internal limit of the number of overload signatures that can be captured by a ParamSpec from 64 to 1024.
• Fixed a bug that leads to infinite recursion (stack overflow) under certain circumstances.

Enhancements:

• Added narrowing support for literal patterns in a match statement that are used to discriminate between tagged unions of objects that can be discriminated based on a field with a literal type.

Published 1.1.341

Normally, new pyright releases are published each Tuesday. This is an out-of-cycle release that addresses several regressions introduced in 1.1.340. These were all related to a massive change (one that affected a majority of the source files in pyright) that changed the way that file paths were tracked internally. Pyright now uses URIs rather than simple paths — a change that's needed to support a number of language server features.

Bug Fixes:

• Fixed regression introduced in 1.1.340 that caused a crash in the --verifytypes functionality.
• Fixed regression introduced in 1.1.340 that resulted in an incorrect URI returned as part of a language server "rename" request.
• Fixed regression introduced in 1.1.340 that resulted in an unintended schema change for the outputjson output.
• Fixed regression introduced in 1.1.340 that resulted in a crash when using file watchers (--watch option).
• Fixed regression introduced in 1.1.340 that resulted in incorrect import resolution for certain namespace packages.
• Fixed bug that resulted in a false positive error when one ParamSpec was captured by another ParamSpec.
• Fixed bug related to function type compatibility when the dest type contains an unpacked tuple followed by one or more positional-only parameters as in Callable[[*Ts, int], None].

Enhancements:

• Improved signature help provider so it handles overloaded __init__ and __new__ methods when calling a constructor.
• Updated typeshed stubs to the latest version.

Published 1.1.340

Bug Fixes:

• Fixed English text for position-only error. It contained an extraneous \" at the end.
• Fixed a bug that resulted in a crash under certain circumstances when defining a type alias using a type statement when no type parameters are defined.
• Fixed bug in narrowing logic for sequence pattern magic where special cases of str, bytes, and bytearray were not handled correctly.
• Fixed bug that led to a false positive when a zero-argument form of super is called within an inner function or lambda.
