* [3.10] gh-85267: Improvements to inspect.signature __text_signature__ ↵Shantanu2022-12-211-12/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | handling (GH-98796) (#100393) This makes a couple related changes to inspect.signature's behaviour when parsing a signature from `__text_signature__`. First, `inspect.signature` is documented as only raising ValueError or TypeError. However, in some cases, we could raise RuntimeError. This PR changes that, thereby fixing GH-83685. (Note that the new ValueErrors in RewriteSymbolics are caught and then reraised with a message) Second, `inspect.signature` could randomly drop parameters that it didn't understand (corresponding to `return None` in the `p` function). This is the core issue in GH-85267. I think this is very surprising behaviour and it seems better to fail outright. Third, adding this new failure broke a couple tests. To fix them (and to e.g. allow `inspect.signature(select.epoll.register)` as in GH-85267), I add constant folding of a couple binary operations to RewriteSymbolics. (There's some discussion of making signature expression evaluation arbitrary powerful in GH-68155. I think that's out of scope. The additional constant folding here is pretty straightforward, useful, and not much of a slippery slope) Fourth, while GH-85267 is incorrect about the cause of the issue, it turns out if you had consecutive newlines in __text_signature__, you'd get `tokenize.TokenError`. Finally, the `if name is invalid:` code path was dead, since `parse_name` never returned `invalid`..

* gh-84753: Make inspect.iscoroutinefunction() work with AsyncMock (GH-94050) ↵Miss Islington (bot)2022-06-301-1/+1
| | | | | | | | | | | | | | (GH-94461) The inspect version was not working with unittest.mock.AsyncMock. The fix introduces special-casing of AsyncMock in `inspect.iscoroutinefunction` equivalent to the one performed in `asyncio.iscoroutinefunction`.

| | | * [Enum] revert enum module to 3.9
* bpo-43817: Add inspect.get_annotations(). (#25522)larryhastings2021-04-301-14/+135
| | | | | Add inspect.get_annotations, which safely computes the annotations defined on an object. It works around the quirks of accessing the annotations from various types of objects, and makes very few assumptions about the object passed in. inspect.get_annotations can also correctly un-stringize stringized annotations. inspect.signature, inspect.from_callable, and inspect.from_function now call inspect.get_annotations to retrieve annotations. This means inspect.signature and inspect.from_callable can now un-stringize stringized annotations, too.
* bpo-38605: Revert making 'from __future__ import annotations' the default ↵Pablo Galindo2021-04-211-17/+2
| | | | | | (GH-25490) This reverts commits 044a1048ca93d466965afc027b91a5a9eb9ce23c and 1be456ae9d53bb1cba2b24fc86175c282d1c2169, adapting the code to changes that happened after it.
* bpo-40066: Enum: modify `repr()` and `str()` (GH-22392)Ethan Furman2021-03-311-3/+0
| | | | | | | | | * Enum: streamline repr() and str(); improve docs - repr() is now ``enum_class.member_name`` - stdlib global enums are ``module_name.member_name`` - str() is now ``member_name`` - add HOW-TO section for ``Enum`` - change main documentation to be an API reference
* bpo-42901: [Enum] move member creation to `__set_name__` (GH-24196)Ethan Furman2021-01-131-1/+1
| | | | | | | | | | | `type.__new__` calls `__set_name__` and `__init_subclass__`, which means that any work metaclasses do after calling `super().__new__()` will not be available to those two methods. In particular, `Enum` classes that want to make use of `__init_subclass__` will not see any members. Almost all customization is therefore moved to before the `type.__new__()` call, including changing all members to a proto member descriptor with a `__set_name__` that will do the final conversion of a member to be an instance of the `Enum` class.

* bpo-38605: Make 'from __future__ import annotations' the default (GH-20434)Batuhan Taskaya2020-10-061-2/+17
| | | | | 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).
