New submission from Petr Viktorin <encu...@gmail.com>:
The `replace` method of `code` allows setting e.g. * co_filename to a subclass of str * co_consts to an arbitrary tuple and possibly more weird cases. This makes code objects unmarshallable. One way to create such a code object is to call `compileall.compile_file` with a str subclass as path. See the attached reproducers. This hit pip, see: https://github.com/pypa/pip/pull/10358#issuecomment-914320728 ---------- files: reproducer_replace.py messages: 401277 nosy: petr.viktorin priority: normal severity: normal status: open title: Code objects can contain unmarshallable objects Added file: https://bugs.python.org/file50268/reproducer_replace.py _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue45127> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
