CPython's _PyFrame_GetLocals only syncs fastlocals/cells into locals() for function scope; module/class scope just returns the namespace dict as-is. sync_visible_locals_to_mapping did this for every scope, so the implicit __conditional_annotations__ cell (used for PEP 649/749 deferred annotations) broke two ways: at module scope its cell is always empty, so syncing overwrote the dict's real value with None, causing NameError on the next annotated statement; at class scope its cell is the only real value, so syncing leaked it into locals()/dir(), unlike CPython. Skip cell/free slots outside function scope to match CPython, and add a regression snippet. Closes #8379 Assisted-by: Claude Code:claude-sonnet-5
Test snippets
This directory contains two sets of test snippets which can be run in Python.
The snippets/ directory contains functional tests, and the benchmarks/
directory contains snippets for use in benchmarking RustPython's performance.
Setup
Our testing depends on pytest, which you can install using pip.
Running
Simply run pytest -v in this directory, and the tests should run (and hopefully
pass). If it hangs for a long time, that's because it's building RustPython in
release mode, which should take less time than it would to run every test
snippet with RustPython compiled in debug mode.
