Rollback Strategies

CPython Fallback

The fastest rollback is to delete the cached artifact. Pyvorin will automatically fall back to CPython on the next run:

rm ~/.pyvorin/cache/artifact_*.so

Versioned Artifacts

Store compiled artifacts with version tags:

cp artifact.so artifacts/v1.2.3_main.so
# Rollback
cp artifacts/v1.2.2_main.so ~/.pyvorin/cache/artifact_main.so

Feature Flags

Use environment variables to toggle compilation per function:

if os.environ.get('PYVORIN_ENABLE_MAIN', '1') == '1':
    result = compiled_main()
else:
    result = main()  # CPython fallback

Emergency Stop

export PYVORIN_FORCE_FALLBACK=1

This forces all runs to use CPython regardless of cache state.
