This seems wrong. Doing a normal (in-band) recv() on a closed socket returns an empty string; trying to read OOB data should do the same thing. At worst, it should raise a more specific error. I'm guessing this exception is reflecting an errno of EBADF. A more specific error would at least make it clear that it's the first argument to recv() which was bad, not the second. frame:pyClient$ cat oob.py #!/usr/bin/env python import socket s = socket.socket() s.connect ((localhost, 13)) # 13 = daytime print == , `s.recv(1024)` print OOB: , `s.recv (1024, socket.MSG_OOB)` frame:pyClient$ ./oob.py == 'Mon Dec 12 22:00:29 2005\n\r' OOB: Traceback (most recent call last): File ./oob.py, line 8, in ? print OOB: , `s.recv (1024, socket.MSG_OOB)` socket.error: (22, 'Invalid argument') frame:pyClient$ -- You can respond by visiting: https://sourceforge.net/tracker/?func=detailatid=105470aid=1379209group_id=5470 ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
