23bcbcebfb Fixed bug in code flow engine that led to incorrect type evaluation of a variable in a nested loop. This addresses https://github.com/microsoft/pylance-release/issues/4509. 2023-06-18 17:42:25 -07:00

056415f6f4 Fixed a bug in the control flow debugging code that prints the control flow graph. It was not correctly handling one of the node types which led to incomplete graphs. 2023-06-18 16:40:00 -07:00

Improved type inference for lambdas in the case where a parameter includes a default value and the expected type doesn't include that parameter. This improvement was suggested in the [mypy issue tracker](https://github.com/python/mypy/issues/15459). (#5337)

52c8cac1ff Changed type printer (the component that renders types into text) to use the lowercase type[x] instead of Type[x]. It has now been four years since PEP 585 deprecated the use of the upper-case version, so most developers should be getting comfortable with the lowercase version at this point. 2023-06-18 12:41:24 -07:00

Fixed a bug that led to a false positive error under certain circumstances when a literal type argument was used in conjunction with a protocol that used a covariant type parameter and an implementation of that protocol that used an invariant type parameter. This addresses https://github.com/microsoft/pyright/issues/5282. (#5332)

2b0f8d22cd Improved hover text to display the calculated variance for a PEP 695-style class-scoped type variable when the user hovers over the type parameter in the type param list. 2023-06-18 09:46:18 -07:00

Fixed a bug that led to incorrect type evaluation when passing a generic class (with a constructor that includes class-scoped TypeVars) as an argument for a callable parameter. The class was being specialized prematurely (with type arguments set to Unknown) before the constraint solver was able to solve the higher-order function's type variables. This addresses https://github.com/microsoft/pyright/issues/5324. (#5328)

Clarification of --version argument usage string (#5308) 
* Update command-line.md

clarify that `--version` prints the version *and exits*

* Update --version usage string

Clarifies that `--version` prints the version *and exits*, this is fairly common language used by most CLI apps to indicate what the behavior of `--version` is. It may surprise new users that `--version` exits rather than appending the version with the previous language.

Fixed a bug that leads to a false positive error in the reportIncompatibleMethodOverride check when a child class is overriding an overloaded method in the base class and one or more of the overloads doesn't apply because the self or cls parameter is explicitly annotated in a way that's not applicable to the child class.

Update ci-integration.md (#5259)

Best way to ensure report are always converted, is to use `after_script:` block.
