sending large messages (over 65535 bytes) fails

[d1g1t4l]

I created a multi-megabyte batch and captured the network traffic while trying to send it. Only the first ~65535 bytes of the batch got sent. The problem is in OrientSocket.write in orient.py:

    def write(self, buff):
        return self._socket.send(buff)

This works for small buffers but is not guaranteed to send the full buffer when the size is large. The following code fixes the issue:

    def write(self, buff):
        count = 0
        while count < len(buff):
            count += self._socket.send(buff[count:])
        return count
