Catching Silent Runtime Bugs with pyrift

Описание и применение

pyrift — это инструмент статического анализа для Python, который выявляет скрытые ошибки времени выполнения, связанные с различиями в поведении между версиями CPython или между CPython и PyPy. Он дополняет линтеры и типизаторы, находя проблемы, которые они пропускают.

Задача

Python developers face silent runtime bugs that pass linting and type checking but fail in production due to behavior differences between CPython versions or between CPython and PyPy.

Результат

pyrift identifies 17 specific rules covering CPython version compatibility and PyPy runtime differences, helping developers catch silent bugs that other tools miss.

Рабочий процесс

• Install pyrift via pip: pip install pyrift
• Run the scanner on the project directory: pyrift scan .
• Review the output for errors (e.g., CPY002 for version-specific features) and warnings (e.g., PPY001 for PyPy-specific issues).
• Refactor code to address flagged issues, such as adding version guards or using context managers instead of __del__.
• Integrate pyrift into CI pipelines to fail builds on detected runtime behavior risks.

Доказательства

It statically analyses your Python code and flags patterns that behave differently across CPython versions or between CPython and PyPy.

Источник

Exit code is 1 when errors are found — fails the build automatically.
