The Changing "Guarantees" Given by Python's Global Interpreter Lock
Summary: This blog post examines the implementation details of CPython's Global Interpreter Lock (GIL) and how it has changed between Python 3.9 and the upcoming Python 3.13. The GIL is a single global lock that protects CPython's internal data structures from concurrent access, ensuring correctness. However, Python 3.13 provides much stronger atomicity "guarantees" than Python 3.9, releasing the GIL mainly on function calls and jumps back to the top of a loop or function. This could lead to more people implicitly relying on these guarantees, which may be problematic if the Python community plans to remove the GIL in the future.
