Sep 18, 2023 · PEP 703 poses some issues regarding the stable ABI. I’ve described these issue below along with a short proposal. tl;dr The --disable-gil builds of CPython 3.13 will not be able to load existing wheels that target the stable ABI. However, we can make wheels that target the 3.13+ stable ABI work with both the default (with GIL) and --disable-gil builds going forward. Background CPython C API ...
Nov 15, 2022 · TL;DR: Trail of Bits has developed abi3audit, a new Python tool for checking Python packages for CPython application binary interface (ABI) violations. We’ve used it to discover hundreds of inconsistently and incorrectly tagged package distributions, each of which is a potential source of crashes and exploitable memory corruption due to undetected ABI differences.
Jul 20, 2024 · Python ABI has evolved over time, and different versions of Python have different ABI specifications. Python 3.13, for example, will have its own ABI specification, which will be different from previous versions. When working with extension modules, it is essential to ensure that the module is compatible with the version of Python being used ...
Nov 13, 2024 · The abbreviated tags facilitate sharing compiled Python code in a public index. Your Python implementation can use this specification too, but with longer tags. Recall that all “pure Python” built distributions just use py. Why is the ABI tag (the second tag) sometimes “none” in the reference implementation?
Python's stable ABI has its issues. It is ill-defined. According to PEP 384, functions are opt-out: all functions not specially marked are part of the stable ABI. But in practice, for Windows there's a list that's opt-in. For users there is a #define that should make only the stable ABI available, but it's not kept up-to date. Neither is the ...

Feb 2, 2021 · The word “Extensions” is used as a shorthand for all code that uses the Python API, e.g. extension modules or software that embeds Python. Stable ABI. The CPython Stable ABI is a promise that extensions built against a specific Stable ABI version will be usable with any newer interpreter of the
