Just because a bug hasn't surfaced yet, doesn't make it a non-issue. The problem is also somewhat different for Unicode: Unlike PyString_AsString() a Unicode API PyUnicode_UTF8() would not provide easy access to the length of the returned char*. And there is no PyString_GET_SIZE() you could use to quickly verify that there are no embedded NULs. Which is why using PyUnicode_AsStringAndSize() is the overall better and safer solution. _______________________________________ Python tracker <[EMAIL PROTECTED]> <http://bugs.python.org/issue2799> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
