Bump typing-extensions from 4.11.0 to 4.12.0

HIFIS Bot requested to merge dependabot-pip-typing-extensions-4.12.0 into master

Bumps typing-extensions from 4.11.0 to 4.12.0.

Release notes

Sourced from typing-extensions's releases.

4.12.0

This release focuses on compatibility with the upcoming release of Python 3.13. Most changes are related to the implementation of type parameter defaults (PEP 696).

Thanks to all of the people who contributed patches, especially Alex Waygood, who did most of the work adapting typing-extensions to the CPython PEP 696 implementation.

There is a single change since 4.12.0rc1:

  • Fix incorrect behaviour of typing_extensions.ParamSpec on Python 3.8 and 3.9 that meant that isinstance(typing_extensions.ParamSpec("P"), typing.TypeVar) would have a different result in some situations depending on whether or not a profiling function had been set using sys.setprofile. Patch by Alex Waygood.

Changes included in 4.12.0rc1:

  • Improve the implementation of type parameter defaults (PEP 696)
    • Backport the typing.NoDefault sentinel object from Python 3.13. TypeVars, ParamSpecs and TypeVarTuples without default values now have their __default__ attribute set to this sentinel value.
    • TypeVars, ParamSpecs and TypeVarTuples now have a has_default() method, matching typing.TypeVar, typing.ParamSpec and typing.TypeVarTuple on Python 3.13+.
    • TypeVars, ParamSpecs and TypeVarTuples with default=None passed to their constructors now have their __default__ attribute set to None at runtime rather than types.NoneType.
    • Fix most tests for TypeVar, ParamSpec and TypeVarTuple on Python 3.13.0b1 and newer.
    • Backport CPython PR #118774, allowing type parameters without default values to follow those with default values in some type parameter lists. Patch by Alex Waygood, backporting a CPython PR by Jelle Zijlstra.
    • It is now disallowed to use a TypeVar with a default value after a TypeVarTuple in a type parameter list. This matches the CPython implementation of PEP 696 on Python 3.13+.
    • Fix bug in PEP-696 implementation where a default value for a ParamSpec would be cast to a tuple if a list was provided. Patch by Alex Waygood.
  • Fix Protocol tests on Python 3.13.0a6 and newer. 3.13.0a6 adds a new __static_attributes__ attribute to all classes in Python, which broke some assumptions made by the implementation of typing_extensions.Protocol. Similarly, 3.13.0b1 adds the new __firstlineno__ attribute to all classes.
  • Fix AttributeError when using typing_extensions.runtime_checkable in combination with typing.Protocol on Python 3.12.2 or newer. Patch by Alex Waygood.
  • At runtime, assert_never now includes the repr of the argument

This release is mostly the same as 4.12.0rc1 but fixes one more longstanding bug.
