Changelog¶

1.10.0 (2023-12-15)¶

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.

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).

Included a pyproject.toml to allow users install the sdist with old python/setuptools, as the setuptools-scm dep will be fetched by pip instead of setuptools. Fixes #30.

Fixed wheels being built with -coverage cflags. No more issues about bogus cext.gcda files.
Removed useless C file from wheels.
Changed setup.py to use setuptools-scm.

Fix a memory leak (the wrapped object would get bogus references). Contributed by Astrum Kuo in #10.

Don’t instantiate the object when __repr__ is called. This aids with debugging (allows one to see exactly in what state the proxy is).

Added support for pickling. The pickled value is going to be the wrapped object without any Proxy container.
Fixed a memory management issue in the C extension (reference cycles weren’t garbage collected due to improper handling in the C extension). Contributed by Alvin Chow in #8.
