Catching Silent Runtime Bugs with pyrift

说明与用途

pyrift 是一个 Python 静态分析工具，用于检测由于 CPython 版本之间或 CPython 与 PyPy 之间的行为差异导致的静默运行时错误。它补充了 linter 和类型检查器，能够发现它们遗漏的问题。

问题

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.

结果

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

工作流

• 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.

证据

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

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