pitrou> The documentation for PyArg_ParseTuple states that the pitrou> "I" code doesn't do any overflow checking. Does it mean pitrou> the input parameters can be silently truncated? I'm sorry, but you're right :-) My patch was wrong. New patch introduces functions parse_uid() and parse_gid() doing the right thing to get an unsigned uid and gid. I reused the parsing code from posix_setgroups().
