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

Fixed bug that results in incorrect type evaluation behavior within c… (#7912) 
* Fixed bug that results in incorrect type evaluation behavior within class body of an enum class when one enum member is used to define another enum member. This involved a significant rewrite of the logic involving enum symbol evaluation. It addresses #7763.

* Add recursion protection.

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__.

92f2284d24 Changed behavior when evaluating the upper bound expression, value constraints expression, or default expression for a PEP-695 type parameter.

Fixed a bug that leads to inconsistent behaviors when an assignment leads to a type violation. When assigning to a local variable, the target expression is not "narrowed" to include the assigned type in this case.
