We're excited to share this library with you, designed to help you build high-performance applications with Free Threaded Python.
ft_utils is open-source software, licensed under the permissive MIT license. You can find the full license terms in our LICENSE file.
We'd love for you to contribute to ft_utils! To ensure that our codebase remains maintainable and efficient, we follow some simple guidelines. Please take a look at our CONTRIBUTING.md document for more information.
In addition to these guidelines, we have a few extra rules to keep in mind:
- Language: We use C11 and Python as our only programming languages. Build scripts can be in other languages.
- Cross-Platform Compatibility: Our code must compile on Windows, Linux, and Mac(arm).
- GIL and Free Threaded Python: All functionality should work seamlessly on both GIL and Free Threaded Python, although results may vary slightly between the two environments.
- Unit Tests: Every feature must have at least one unit test to ensure it works correctly.
- Benchmarks: It is best practice to write benchmarks for all new features to further test and to drive our aim of high performance.
See to documentation.
At the time of writing ft_utils is a source only distribution. You will need to build the wheel yourself.
You will need a source code version of CPython. To run for Free Threaded Python, at the time of writing, this means you will require CPython 3.13 and compile as 3.13t. This code will also compile under 3.12 but then you only get the GIL version.
Please ensure you are in a virtual environment. If you cannot, or do not wish to do this then you will need to coomment out the call to check_env() in setup.py.
Once you have everything in place, please execute setup.py as a python script:
python setup.py
If this does not work due to networking then you might need use a proxy; for example:
https_proxy=http://fwdproxy:8080 python setup.py
The code in ft_utils is built and tested interally within Meta. At the time of writing there is no external CI.
However, once installed you can test the code via python -m ft_utils.tests.test_run_all. This will not work if your current working directory is the ft_utils source director (due to name clash). This will run all the tests and benchmarks which are known good and report any failures.
