Sep 4, 2021 · On some platforms, Python will look for and load shared library files named with the abi3 tag (e.g. mymodule.abi3.so). It does not check if such extensions conform to a Stable ABI. The user (or their packaging tools) need to ensure that, for example, extensions built with the 3.10+ Limited API are not installed for lower versions of Python.
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 ...
Jul 20, 2024 · Here is an example of how the Python ABI is used in CPython. Consider the following Python code: import math. result = math.sqrt(16.0) This code imports the math module and calls the sqrt() function to calculate the square root of 16.0. The math module is implemented as a C extension module, which is linked dynamically to the Python interpreter.
Sep 28, 2023 · Triple quotes turn your ABI into a string instead of a dictionary. If you want to go the string route, you need to turn the string back into a data structure with something like json.loads (that will parse your JSON)/. For example: import json. ERC20_ABI = """[.
Nov 15, 2022 · An Application Binary Interface (ABI), allowing any language with C ABI support (like Rust or Golang) to link against CPython’s runtime and use the same internals. Developers can use the CPython API and ABI to write CPython extensions. These extensions behave exactly like ordinary Python modules but interact directly with the interpreter’s ...
Sep 18, 2023 · (Cross-posting here on @pf_moore’s suggestion. Please comment on the original post.) I’ve posted a proposal to add a few functions to the stable ABI, which will allow cp313-abi3 stable ABI wheels to be supported by both the default 3.13+ CPython builds and the (experimental) --disable-gil builds. Here’s my packaging tools focused summary: cp313-abi3 wheels will work with CPython 3.13 ...

In other words: if you build against the stable ABI for Python 3.5, your extension should work without modification on Python 3.9. The stable ABI simplifies packaging of CPython extensions, since the packager only needs to build one abi3 wheel that targets the minimum supported Python version. To signal that a Python wheel contains abi3 ...
