propcache
The module provides a fast implementation of cached properties for Python 3.10+.
Introduction
The API is designed to be nearly identical to the built-in functools.cached_property class, except for the additional under_cached_property class which uses self._cache instead of self.__dict__ to store the cached values and prevents __set__ from being called.
For full documentation please read https://propcache.readthedocs.io.
Installation
$ pip install propcache
The library is Python 3 only!
PyPI contains binary wheels for Linux, Windows and MacOS. If you want to install propcache on another operating system where wheels are not provided, the the tarball will be used to compile the library from the source code. It requires a C compiler and and Python headers installed.
To skip the compilation you must explicitly opt-in by using a PEP 517 configuration setting pure-python, or setting the PROPCACHE_NO_EXTENSIONS environment variable to a non-empty value, e.g.:
$ pip install propcache --config-settings=pure-python=falsePlease note that the pure-Python (uncompiled) version is much slower. However, PyPy always uses a pure-Python implementation, and, as such, it is unaffected by this variable.

The project is hosted on GitHub
Please file an issue on the bug tracker if you have found a bug or have some suggestion in order to improve the library.

Dropped support for Python 3.9 as it has reached end of life.

Packaging updates and notes for downstreams
Changed the Cython build dependency from ~= 3.1.0 to >= 3.2.0, removing the upper version bound to avoid conflicts for downstream packagers – by @jameshilliard and @gundalow.
The upstream Cython version is pinned to 3.2.4 in the CI/CD environment.
Related issues and pull requests on GitHub: #184, #188, #214.
Start building and shipping riscv64 wheels – by @justeph.
Related issues and pull requests on GitHub: #194.
The PEP 517 build backend now supports a new build-inplace config setting (and PROPCACHE_BUILD_INPLACE environment variable) for controlling whether to build the project in-tree or in a temporary directory. It only affects wheels and is set up to build in a temporary directory by default. It does not affect editable wheel builds; they will keep being built in-tree regardless.
Here’s an example of using this setting:
$ python -m build --config-setting=build-inplace=trueAdditionally, when building wheels in an automatically created temporary directory, the build backend now normalizes the respective file system path to a deterministic source checkout directory by injecting the -ffile-prefix-map compiler option into the CFLAGS environment variable, as suggested by known reproducible build practices.
The effect is that downstreams will get reproducible build results.

Fixes the default value for the os parameter in reusable-build-wheel.yml to be ubuntu-latest instead of ubuntu.

Contributor-facing changes
Builds have been added for arm64 Windows wheels and the reusable-build-wheel.yml workflow has been modified to allow for an OS value (windows-11-arm) which does not include the -latest postfix – by @finnagin.

Added CI for CPython 3.14 – by @kumaraditya303.

0.3.2
(2025-06-09)
Improved documentation
Packaging updates and notes for downstreams
Updated to use Cython 3.1 universally across the build path – by @lysnikolaou.
Related issues and pull requests on GitHub: #117.
Made Cython line tracing opt-in via the with-cython-tracing build config setting – by @bdraco.
Previously, line tracing was enabled by default in pyproject.toml, which caused build issues for some users and made wheels nearly twice as slow.
Now line tracing is only enabled when explicitly requested via pip install . --config-setting=with-cython-tracing=true or by setting the PROPCACHE_CYTHON_TRACING environment variable.
