IMO %.200s is a bug here. We should no longer truncate type names if they are too long. Many years ago, Python had an internal buffer of a fixed size and so the overall string must not be too long. But this has been fixed.
Please don't truncate type names.

If you want to log i variable, you should add %i somewhere.

LGTM. I just left two minor suggestions.

I wanted to do this change for many years. It's awful to get a warning without any context :-( Thanks for this nice enhancement! I like PyErr_FormatUnraisable() API! |
