[ros-users] socket error

[Ken Conley]

Hi Arjun,

The necessary info is missing due to a bug in the call to the logger.
Can you try the attached patch?

Also, can you confirm that your roslib/src/roslib/xmlrpc.py ends with
the code block below?

thanks,
Ken

        while not self.is_shutdown:
            try:
                self.server.serve_forever()
            except IOError as (errno, errstr):
                # check for interrupted call, which can occur if we're
                # embedded in a program using signals.  All other
                # exceptions break _run.
                if self.is_shutdown:
                    pass
                elif errno != 4:
                    self.is_shutdown = True
                    logger.error("serve forever IOError: %s,
%s"%(errno, errstr))
                    raise
            except:
                if self.is_shutdown:
                    pass
                else:
                    raise
