Message6681

socket.getaddrinfo sometimes returns an object that crashes in __str__ (so it can't be printed). This is caused by a port number being None where a format string expects an int (%d).

Reproduce session:

>>> import socket
>>> socket.getaddrinfo("",None)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "E:\projects\jython\dist\Lib\socket.py", line 647, in __str__
    return "('%s', %d)" % (self.sockaddr, self.port)
TypeError: int argument required
