Copilotandyouknowone 76755524df Add __callback__ property to weakref type (#7590)
* Initial plan

* Add __callback__ property to PyWeak for weakref compatibility

Add get_callback() method to PyWeak in core.rs that safely reads the
callback field under the stripe lock. Expose it as a read-only
__callback__ property on the weakref type, matching CPython behavior:
- Returns the callback function when one was provided and referent is alive
- Returns None when no callback was provided
- Returns None after the referent has been collected
- Raises AttributeError on assignment (read-only)

Remove @unittest.expectedFailure from test_callback_attribute and
test_callback_attribute_after_deletion in test_weakref.py.

Add regression tests to extra_tests/snippets/stdlib_weakref.py.

Standard Library for RustPython

This directory contains all of the Python files that make up the standard library for RustPython.

Most of these files are copied over from the CPython repository (the 3.7 branch), with slight modifications to allow them to work under RustPython. The current goal is to complete the standard library with as few modifications as possible. Current modifications are just temporary workarounds for bugs/missing feature within the RustPython implementation.

The first big module we are targeting is unittest, so we can leverage the CPython test suite.
