* gh-108751: Add copy.replace() function (GH-108752)Serhiy Storchaka2023-09-061-0/+4
| | | | | | | | | It creates a modified copy of an object by calling the object's __replace__() method. It is a generalization of dataclasses.replace(), named tuple's _replace() method and replace() methods in various classes, and supports all these stdlib classes.

* gh-102856: Python tokenizer implementation for PEP 701 (#104323)Marta Gómez Macías2023-05-211-2/+2
| | | | | | | | | | | This commit replaces the Python implementation of the tokenize module with an implementation that reuses the real C tokenizer via a private extension module. The tokenize module now implements a compatibility layer that transforms tokens from the C tokenizer into Python tokenize tokens for backward compatibility. As the C tokenizer does not emit some tokens that the Python tokenizer provides (such as comments and non-semantic newlines), a new special mode has been added to the C tokenizer mode that currently is only used via the extension module that exposes it to the Python layer. This new mode forces the C tokenizer to emit these new extra tokens and add the appropriate metadata that is needed to match the old Python implementation.

* 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`
