Bug Fix: Reverted a recent update to the TOML parser that resulted in a regression. This reversion means that some TOML 1.0 features will not be handled correctly.
Bug Fix: Fixed a bug that resulted in incorrect handling of literals in the TypeVar constraint solver. This involved a pretty significant change to the constraint solver logic — one that eliminated some heuristics and special cases.
Bug Fix: Fixed a bug that caused target expressions within a chained assignment to be evaluated in the wrong order (right to left instead of left to right). This resulted in false positives and negatives in some cases where one target referred to another target. This change also makes it illegal to use a Python 2-style type comment on a line containing a chained assignment statement, reflecting the fact that Python 3-style variable type annotations are not legal here either.
Enhancement: Improved handling of TypeVarTuple constraint solving. Previously, if a TypeVarTuple appeared more than once, the corresponding tuple types needed to be identical. The constraint solver now supports the same sort of narrowing/widening within the tuple entries to find the best solution.
Bug Fix: Fixed a bug that led to a false negative during protocol matching if the protocol class refers to itself within an invariant type argument.
Enhancement: Improved handling of generic functions passed as arguments to generic higher-order functions. Pyright is now able to solve the type variables for both the generic callback and the called function.
Enhancement: Updated typeshed stubs to the latest version.
Enhancement: Improved handling of generic functions passed as arguments to generic higher-order functions that use a ParamSpec. Pyright is now able to solve the type variables for both the generic callback and the called function.
Bug Fix: Fixed a bug in the code flow engine that resulted in incorrect type evaluation in some cases involving double nested loops.
Bug Fix: Improved the method override consistency checks to detect the case where an override uses an *args parameter that is not type compatible with the overridden method's parameter types. Thanks to @mehdigmira for this contribution.
Enhancement: Improved handling of TypeVars that appear only within a Callable within a return type annotation for a function. By a strict reading of PEP 484, these should be bound to the function's scope, but practically, they are bound to the Callable. This allows a function to return a generic callable type. When TypeVars are rescoped in this manner, the TypeVar cannot be referenced within the function body because it is no longer in scope in that context.
Enhancement: Improved error handling for NewType calls
Enhancement: Completed initial implementation of PEP 696. Added support for default TypeVar types that refer to other TypeVars.
Published 1.1.285
Enhancement: Implemented a new --level command-line option that allows filtering of 'information' and 'warning' diagnostics.
Enhancement: Updated TOML parser to one that is compliant with the TOML 1.0 spec.
Enhancement: Added logic to detect uses of PEP 604 | syntax that generate exceptions due to runtime limitations. In particular, if one of the operands is a string (i.e. a forward reference) and the other is also a string or a class that is not explicitly specialized, this will result in an exception.
Bug Fix: Fixed recent regression in completion provider that resulted in garbled type information for a symbol that is declared as a function (using a def statement) but transformed into a non-function type using a decorator.
Bug Fix: Fixed a bug that resulted in a false positive error when an index expression with a numeric literal subscript was used in a loop that included a del statement targeting the same index expression.
Behavior Change: Modified the overload matching algorithm to match the behavior of mypy when the overload match is ambiguous because an argument evaluates to Any or Unknown. In this case, the call expression evaluates to Unknown. Previously, pyright used the first of the matching overloads in this case.
Bug Fix: Fixed a bug that led to extremely long type analysis times when determining type compatibility between an recursive type alias and a recursive protocol.
Bug Fix (contribution from @parched): Fixed recent regression that caused reportImportCycles diagnostic reporting to no longer work.
Bug Fix: Fixed a bug that resulted in a false positive error when a property setter or deleter contained function-scoped type variables.
Published 1.1.284
Bug Fix: Fixed a bug that resulted in an incorrect type evaluation when using a literal integer index into a tuple that includes an unpacked TypeVarTuple element.
Behavior Change: Removed diagnostic check that detects a non-ellipsis default value in a stub file. This check was based on a now-outdated best practice. We now recommend that stubs include default values for better usability in language servers.
