* gh-94912: Adjusted check for non-standard coroutine function marker. (#100935)Carlton Gibson2023-01-111-2/+0
| | | | | | The initial implementation did not correctly identify explicitly marked class instances. Follow up to 532aa4e4e019812d0388920768ede7c04232ebe1
* gh-85267: Improvements to inspect.signature __text_signature__ handling (#98796)Shantanu2022-12-211-5/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 #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 #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 #85267), I add constant folding of a couple binary operations to RewriteSymbolics. (There's some discussion of making signature expression evaluation arbitrary powerful in #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 #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-94912: Added marker for non-standard coroutine function detection (#99247)Carlton Gibson2022-12-181-2/+24
| | | | | This introduces a new decorator `@inspect.markcoroutinefunction`, which, applied to a sync function, makes it appear async to `inspect.iscoroutinefunction()`.
* gh-100039: enhance __signature__ to work with str and callables (GH-100168)Ethan Furman2022-12-161-1/+9
| | | | | Callables should be either class- or static-methods. Enum now uses the classmethod version to greatly improve the help given for enums and flags.

* bpo-33587: inspect.getsource: reorder stat on file in linecache (GH-6805)Pankaj Pandey2022-08-261-3/+3
| | | | | | | | | | * inspect.getsource: avoid stat on file in linecache The check for os.path.exists() on source file is postponed in inspect.getsourcefile() until needed avoiding an expensive filesystem stat call and PEP 302 module loader check is moved last for performance since it is an uncommon case.
* gh-84753: Make inspect.iscoroutinefunction() work with AsyncMock (#94050)Mehdi ABAAKOUK2022-06-301-1/+1
| | | | | | | | | 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`. Co-authored-by: Łukasz Langa <lukasz@langa.pl>

* bpo-40066: [Enum] update str() and format() output (GH-30582)Ethan Furman2022-01-161-16/+14
| | | | | | | | | | | | | | | Undo rejected PEP-663 changes: - restore `repr()` to its 3.10 status - restore `str()` to its 3.10 status New changes: - `IntEnum` and `IntFlag` now leave `__str__` as the original `int.__str__` so that str() and format() return the same result - zero-valued flags without a name have a slightly changed repr(), e.g. `repr(Color(0)) == '<Color: 0>'` - update `dir()` for mixed-in types to return all the methods and attributes of the mixed-in type - added `_numeric_repr_` to `Flag` to control display of unnamed values - enums without doc strings have a more comprehensive doc string added - `ReprEnum` added -- inheriting from this makes it so only `__repr__` is replaced, not `__str__` nor `__format__`; `IntEnum`, `IntFlag`, and `StrEnum` all inherit from `ReprEnum`

* 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-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).
