lazy-object-proxy

• Added Python 3.12 wheels.

• Dropped support for Python 3.7.

• Applied some reformatting and lint fixes using ruff to the codebase (mostly more Python 2 leftover cleanups).

• Added support for matrix multiplication operator (@).

• Should have all the wheels now (including the manylinux ones).

• Bumped minimum version requirements for setuptools and setuptools-scm.

• Switched the default pure python fallback implementation to the "simple" one (when you from lazy_object_proxy import Proxy and the C extension is not available). Previously the "slots" implementation was used but as it turns out it is slower on Python 3.

• Cleaned up use of cPickle. Contributed by Sandro Tosi in #62.

• Cleaned up more dead Python 2 code.

• Added Python 3.11 wheels.

• Dropped support for Python 3.6.

• Removed most of the Python 2 support code and fixed python_requires to require at least Python 3.6.

  Note that 1.7.0 has been yanked because it could not install on Python 2.7. Installing lazy-object-proxy on Python 2.7 should automatically fall back to the 1.6.0 release now.

• Switched CI to GitHub Actions, this has a couple consequences:

  • Support for Python 2.7 is dropped. You can still install it there but it's not tested anymore and Python 2 specific handling will be removed at some point.

  • Linux wheels are now provided in musllinux and manylinux2014 variants.

• Fixed __index__ to fallback to int if the wrapped object doesn't have an __index__ method. This prevents situations where code using a proxy would otherwise likely just call int had the object not have an __index__ method.

• Added support for async special methods (__aiter__, __anext__, __await__, __aenter__, __aexit__). These are used in the async for, await` and ``async with statements.

  Note that __await__ returns a wrapper that tries to emulate the crazy stuff going on in the ceval loop, so there will be a small performance overhead.

• Added the __resolved__ property. You can use it to check if the factory has been called.

• Added Python 3.9 wheels.

• Removed Python 2.7 Windows wheels (not supported on newest image with Python 3.9).

First release on PyPI.
