What problem does it solve?

This Skill helps compare CPython source code between two Python versions to identify changes in headers, structs, and APIs that affect our codebase.

Core Features & Use Cases

  • Prepare CPython repo: Clone and fetch tags to a local copy for comparison.
  • Header/struct comparison: Use diffs to identify changes in Include/internal headers and PyObject structures.
  • Impact assessment: Highlight breaking changes and migration paths for our code.

Quick Start

Clone CPython to ~/dd/cpython if needed and compare versions with git diff:

  • git diff OLD_VERSION NEW_VERSION -- Include/internal/pycore_frame.h
  • git diff OLD_VERSION NEW_VERSION -- Include/frameobject.h
  • git diff OLD_VERSION NEW_VERSION -- Include/internal/pycore*.h
