| | | | | | | | | Because setting non-empty _name affects behavior of other code. In most cases __name__ can be derived from __origin__.__name__. (cherry picked from commit 4ceec495598e78f0776dd46d511dcc612a434dc3) Co-authored-by: Serhiy Storchaka <storchaka@gmail.com>

Use also term "arguments" instead of "parameters" in error message for too few/many arguments.

* bpo-41249: Fix postponed annotations for TypedDict (GH-27017) (#27204)Miss Islington (bot)2021-07-171-0/+10
| | | | | | | | | | This fixes TypedDict to work with get_type_hints and postponed evaluation of annotations across modules. This is done by adding the module name to ForwardRef at the time the object is created and using that to resolve the globals during the evaluation.

* bpo-44098: Drop ParamSpec from most ``__parameters__`` in typing generics ↵Miss Islington (bot)2021-05-131-0/+25
| | | | | | | | | | | (GH-26013) (#26091) Added two new attributes to ``_GenericAlias``: * ``_typevar_types``, a single type or tuple of types indicating what types are treated as a ``TypeVar``. Used for ``isinstance`` checks. * ``_paramspec_tvars ``, a boolean flag which guards special behavior for dealing with ``ParamSpec``. Setting it to ``True`` means this class deals with ``ParamSpec``.

* bpo-38605: Revert making 'from __future__ import annotations' the default ↵Pablo Galindo2021-04-211-11/+11
| | | | | | (GH-25490) This reverts commits 044a1048ca93d466965afc027b91a5a9eb9ce23c and 1be456ae9d53bb1cba2b24fc86175c282d1c2169, adapting the code to changes that happened after it.

| | | | | | | | | | | | | | | Noticed by @serhiy-storchaka in the bpo. `typing`'s types were not showing the parameterized generic. Eg. previously: ```python >>> typing.Union[dict[str, float], list[int]] 'typing.Union[dict, list]' ``` Now: ```python >>> typing.Union[dict[str, float], list[int]] 'typing.Union[dict[str, float], list[int]]' ``` Automerge-Triggered-By: GH:gvanrossum
* bpo-41923: PEP 613: Add TypeAlias to typing module (#22532)Mikhail Golubev2020-10-071-0/+40
| | | | | This special marker annotation is intended to help in distinguishing proper PEP 484-compliant type aliases from regular top-level variable assignments.
* bpo-38605: Make 'from __future__ import annotations' the default (GH-20434)Batuhan Taskaya2020-10-061-12/+12
| | | | | The hard part was making all the tests pass; there are some subtle issues here, because apparently the future import wasn't tested very thoroughly in previous Python versions. For example, `inspect.signature()` returned type objects normally (except for forward references), but strings with the future import. We changed it to try and return type objects by calling `typing.get_type_hints()`, but fall back on returning strings if that function fails (which it may do if there are future references in the annotations that require passing in a specific namespace to resolve).

* bpo-41341: Recursive evaluation of ForwardRef in get_type_hints (#21553)wyfo2020-07-221-0/+6
| | | | | | The issue raised by recursive evaluation is infinite recursion with recursive types. In that case, only the first recursive ForwardRef is evaluated.
