Vendored/adapted CPython standard library and CPython test suite used for compatibility validation.
| Task | Location | Notes |
|---|---|---|
| Stdlib sources | 3/ |
CPython stdlib tree. |
| CPython tests | 3/test/ |
Large upstream test suite; GraalPy runs selected tests via tag files. |
| Local lint configs | 3/test/.ruff.toml, 3/test/**/mypy.ini |
Primarily for the vendored tests area. |
- Treat this tree as upstream-ish: changes should be minimal, well-justified, and ideally correspond to upstream fixes.
- Don’t apply sweeping refactors or formatting changes here; it makes rebasing/upstream sync harder.
