This test will not work until the `__buffer__` and `__release_buffer__`
methods are implemented on the appropriate builtin types, which is
outside the current scope.
The original hash algorithm just XOR'd all the hashes of the elements of
the set, which is problematic. The CPython algorithm is required to pass
the tests.
- Replace `PyFrozenSet::hash` with CPython's algorithm
- Remove unused `hash_iter_unorded` functions
- Add `frozenset` benchmark
- Enable tests
- Lower performance expectations on effectiveness test
- Adjust `slot::hash_wrapper` so that it doesn't rehash the computed
hash value in the process of converting PyInt to PyHash.
Python does not define `list().__bool__`, `dict().__bool__`, and
`str().__bool__`, and some tests were failing because they were
defined.
I could not find any references to them and deleting them doesn't
seem to break anything.
Clean implementation of changes in PR #3371 based on feedback.
Copies from [CPython tag `v3.9.7` and adds back custom RustPython changes where needed for:
- `Lib/collections/__init__.py`
- `Lib/test/test_collections.py`
Closes: #3371
