* gh-121027: Add a future warning in functools.partial.__get__ (#121086)Serhiy Storchaka2024-06-271-4/+4

* gh-120381: Fix inspect.ismethoddescriptor() (#120383)Jan Kaliszewski2024-06-181-4/+7
| | | | | | | | The `inspect.ismethoddescriptor()` function did not check for the lack of `__delete__()` and, consequently, erroneously returned True when applied to *data* descriptors with only `__get__()` and `__delete__()` defined.

| | | | | | | | | (GH-115270) Now inspect.signature() supports references to the module globals in parameter defaults on methods in extension modules. Previously it was only supported in functions. The workaround was to specify the fully qualified name, including the module name.

* bpo-38364: unwrap partialmethods just like we unwrap partials (#16600)Martijn Pieters2024-02-151-2/+4
| | | | | | | | | | | | | * bpo-38364: unwrap partialmethods just like we unwrap partials The inspect.isgeneratorfunction, inspect.iscoroutinefunction and inspect.isasyncgenfunction already unwrap functools.partial objects, this patch adds support for partialmethod objects as well. Also: Rename _partialmethod to __partialmethod__. Since we're checking this attribute on arbitrary function-like objects, we should use the namespace reserved for core Python. --------- Co-authored-by: Petr Viktorin <encukou@gmail.com>

| | | | | | | | | 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.
