New submission from STINNER Victor <victor.stin...@haypocalc.com>:
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
:-)
