mx.graalpython/ — MX BUILD TOOLING

OVERVIEW

mx suite definition and Python utilities used for building, testing, benchmarking, and CI orchestration.

WHERE TO LOOK

Task	Location	Notes
Suite definition	suite.py	Defines projects, imports, distributions, version metadata.
mx commands	mx_graalpython.py	Implements custom mx commands (e.g., test runners).
Import helpers	mx_graalpython_import.py	mx sforceimport-related logic.
Bench tooling	mx_graalpython_benchmark.py, mx_graalpython_python_benchmarks.py	Performance harness integration.
Bisect tooling	mx_graalpython_bisect.py	Benchmark/test bisect support.

CONVENTIONS

• Pylint is enforced (via pre-commit) only for mx.graalpython/*.py.
• Treat suite.py as the authoritative dependency/version map; CI workflows typically call into these mx gates.

ANTI-PATTERNS

• Don’t re-implement build/test flows in ad-hoc scripts when an mx command already exists.
• Avoid adding heavyweight dependencies here; this code runs in many CI contexts.
