Content
Guido created the "convenience function" PyErr_Format() 13 years ago (r7580) with a naive implementation using char buffer[500] and vsprintf(). He added a comment: /* Caller is responsible for limiting the format */ Ok, that was true 13 years ago. But today Python uses dynamically allocated buffers, and so we can simply replace %.100s ("%\.[0-9]+s" regex) by %s. Anyway, PyUnicode_FromFormatV() doesn't support precision for %s and %U formats :-)
