STINNER Victor added the comment: Ah yes. Some months (years?) ago, i started to add assertions to fail if some functions are called with an exception set.
Checking if an exception is set at runtime adds a low overhead. Maybe it's better to fail with a fatal error (like an assertion error) in debug mode (and do nothing in release mode). But I'm not sure that developers of C extensions are all able to get a Python compiled in debug mode :-/ That's also why I added a check a runtime: raise a SystemError if a function with an exception set. I also added PYTHONMALLOC=debug to make some debug checks easily available on release builds. The bug also reminds me my PEP 490 to chain exceptions. It would be yet another option... So well, I don't know what is the best option. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue26776> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
