* gh-92106: Add test that subscription works on arbitrary TypedDicts (GH-92176)Miss Islington (bot)2022-05-031-0/+13
| | | | | (cherry picked from commit 81fb3548be5a18bf40a6f4505a02cc7fb72c9c34) Co-authored-by: Serhiy Storchaka <storchaka@gmail.com>
* bpo-46333: Honor `module` parameter in ForwardRef (GH-30536)Miss Islington (bot)2022-02-171-0/+12
| | | | | | | | | | | | The `module` parameter carries semantic information about the forward ref. Forward refs are different if they refer to different module even if they have the same name. This affects the `__eq__`, `__repr__` and `__hash__` methods.

* bpo-46539: Pass status of special typeforms to forward references (GH-30926)Miss Islington (bot)2022-01-271-0/+14
| | | | | | | | | | | Previously this didn't matter because there weren't any valid code paths that could trigger a type check with a special form, but after the bug fix for `Annotated` wrapping special forms it's now possible to annotate something like `Annotated['ClassVar[int]', (3, 4)]`. This change would also be needed for proposed future changes, such as allowing `ClassVar` and `Final` to nest each other in dataclasses.

| | | | | | | | | | | | This implements things like `list[int]`, which returns an object of type `types.GenericAlias`. This object mostly acts as a proxy for `list`, but has attributes `__origin__` and `__args__` that allow recovering the parts (with values `list` and `(int,)`. There is also an approximate notion of type variables; e.g. `list[T]` has a `__parameters__` attribute equal to `(T,)`. Type variables are objects of type `typing.TypeVar`.

| | | | | | | | | | | | | | | | | | | | | | | | | * bpo-39491: Merge PEP 593 (typing.Annotated) support PEP 593 has been accepted some time ago. I got a green light for merging this from Till, so I went ahead and combined the code contributed to typing_extensions[1] and the documentation from the PEP 593 text[2]. My changes were limited to: * removing code designed for typing_extensions to run on older Python versions * removing some irrelevant parts of the PEP text when copying it over as documentation and otherwise changing few small bits to better serve the purpose * changing the get_type_hints signature to match reality (parameter names) I wasn't entirely sure how to go about crediting the authors but I used my best judgment, let me know if something needs changing in this regard.

* bpo-29262: Add get_origin() and get_args() introspection helpers to typing ↵Ivan Levkivskyi2019-05-301-0/+37
| | | | | | | | | | (GH-13685) This is an old feature request that appears from time to time. After a year of experimenting with various introspection capabilities in `typing_inspect` on PyPI, I propose to add these two most commonly used functions: `get_origin()` and `get_args()`. These are essentially thin public wrappers around private APIs: `__origin__` and `__args__`. As discussed in the issue and on the typing tracker, exposing some public helpers instead of `__origin__` and `__args__` directly will give us more flexibility if we will decide to update the internal representation, while still maintaining backwards compatibility. The implementation is very simple an is essentially a copy from `typing_inspect` with one exception: `ClassVar` was special-cased in `typing_inspect`, but I think this special-casing doesn't really help and only makes things more complicated.
