* bpo-29262: Add get_origin() and get_args() introspection helpers to typing ↵Ivan Levkivskyi2019-05-301-0/+42
| | | | | | | | | | (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.

* bpo-37058: PEP 544: Add Protocol to typing module (GH-13585)Ivan Levkivskyi2019-05-281-111/+231
| | | | | I tried to get rid of the `_ProtocolMeta`, but unfortunately it didn'y work. My idea to return a generic alias from `@runtime_checkable` made runtime protocols unpickleable. I am not sure what is worse (a custom metaclass or having some classes unpickleable), so I decided to stick with the status quo (since there were no complains so far). So essentially this is a copy of the implementation in `typing_extensions` with two modifications: * Rename `@runtime` to `@runtime_checkable` (plus corresponding updates). * Allow protocols that extend `collections.abc.Iterable` etc.
* bpo-37049: PEP 589: Add TypedDict to typing module (GH-13573)Ivan Levkivskyi2019-05-261-0/+84
| | | | The implementation is straightforward and essentially is just copied from `typing_extensions`.
* bpo-37046: PEP 586: Add Literal to typing module (#13572)Ivan Levkivskyi2019-05-261-0/+27
| | | | The implementation is straightforward and essentially is just copied from `typing_extensions`.
* bpo-37045: PEP 591: Add final qualifiers to typing module (GH-13571)Ivan Levkivskyi2019-05-261-3/+49
| | | | The implementation is straightforward, it just mimics `ClassVar` (since the latter is also a name/access qualifier, not really a type). Also it is essentially copied from `typing_extensions`.
* bpo-36972: Add SupportsIndex (GH-13448)Paul Dagnelie2019-05-221-0/+9
| | | | In order to support typing checks calling hex(), oct() and bin() on user-defined classes, a SupportIndex protocol is required. The ability to check these at runtime would be good to add for completeness sake. This is pretty much just a copy of SupportsInt with the names tweaked.

* bpo-32873: Treat type variables and special typing forms as immutable by ↵Ivan Levkivskyi2018-03-261-5/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | copy and pickle (GH-6216) This also fixes python/typing#512 This also fixes python/typing#511 As was discussed in both issues, some typing forms deserve to be treated as immutable by copy and pickle modules, so that: * copy(X) is X * deepcopy(X) is X * loads(dumps(X)) is X # pickled by reference This PR adds such behaviour to: * Type variables * Special forms like Union, Any, ClassVar * Unsubscripted generic aliases to containers like List, Mapping, Iterable This not only resolves inconsistencies mentioned in the issues, but also improves backwards compatibility with previous versions of Python (including 3.6). Note that this requires some dances with __module__ for type variables (similar to NamedTuple) because the class TypeVar itself is define in typing, while type variables should get module where they were defined. https://bugs.python.org/issue32873

* bpo-28556: typing.get_type_hints: better globalns for classes and modules ↵Łukasz Langa2017-09-141-9/+18
| | | | | | | | | | | | | | | (#3582) This makes the default behavior (without specifying `globalns` manually) more predictable for users, finds the right globalns automatically. Implementation for classes assumes has a `__module__` attribute and that module is present in `sys.modules`. It does this recursively for all bases in the MRO. For modules, the implementation just uses their `__dict__` directly. This is backwards compatible, will just raise fewer exceptions in naive user code. Originally implemented and reviewed at https://github.com/python/typing/pull/470.
