Hello,
I have released pyrift, which includes 7 PyPy-specific rules that
detect code behaving silently differently on PyPy vs CPython:
PPY001 - __del__ resource cleanup silently leaks due to GC timing
PPY002 - ctypes incomplete implementation
PPY003 - sys.getrefcount() always returns a dummy constant
PPY004 - weakref.proxy() raises ReferenceError unpredictably
PPY005 - file writes may be lost without explicit flush
PPY006 - monkey-patching built-in types behaves differently
PPY007 - sys.intern() identity guarantees not preserved
pip install pyrift && pyrift scan .
GitHub: https://github.com/BHUVANSH855/pyrift
PyPI: https://pypi.org/project/pyrift/
Rule docs: https://github.com/BHUVANSH855/pyrift/blob/main/docs/rules.md
I maintain the pypy-review-toolkit at:
https://github.com/BHUVANSH855/pypy-review-toolkit
I would value feedback from the PyPy team on rule correctness and
any behaviour differences I have missed that would make good additions.
