* [3.10] bpo-46032: Check types in singledispatch's register() at declaration ↵Serhiy Storchaka2021-12-251-0/+68
| | | | | | | | | | time (GH-30050) (GH-30254) The registry() method of functools.singledispatch() functions checks now the first argument or the first parameter annotation and raises a TypeError if it is not supported. Previously unsupported "types" were ignored (e.g. typing.List[int]) or caused an error at calling time (e.g. list[int]). (cherry picked from commit 078abb676cf759b1e960f78390b6e80f256f0255)
* bpo-45678: Add more ``singledispatchmethod`` tests (GH-29412) (GH-29424)Miss Islington (bot)2021-11-051-0/+99
| | | | | | | | | | In order to fix a bug in the 3.9 branch in GH-29394, more tests were added to ``test_functools.py`` to ensure that ``singledispatchmethod`` still correctly wrapped a target method, even if the target method had already been wrapped by multiple other decorators. This PR brings the new tests into the 3.11 and 3.10 branches as well. (cherry picked from commit 32f55d1a5de66f9a86964fc0655d7a006a9d90b9) Co-authored-by: Alex Waygood <Alex.Waygood@Gmail.com>

* bpo-39679: Add tests for classmethod/staticmethod singledispatchmethods ↵Miss Islington (bot)2021-10-191-0/+42
| | | | | | | | | | | | | | | (GH-29034) (GH-29072) In Python 3.8 and 3.9, stacking `@functools.singledispatchmethod` on top of `@classmethod` or `@staticmethod` caused an exception to be raised if the method was registered using type-annotations rather than `@method.register(int)`. This was not caught by unit tests, however, as the tests only tested the `@method.register(int)` way of registering additional implementations. The bug is no longer present in Python 3.10+, but `test_functools.py` is still lacking regression tests for these cases. This commit adds these test cases.

* bpo-38605: Revert making 'from __future__ import annotations' the default ↵Pablo Galindo2021-04-211-2/+2

* bpo-38605: Make 'from __future__ import annotations' the default (GH-20434)Batuhan Taskaya2020-10-061-2/+2
| | | | | 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).
