Replace spinning send_all() with a proper non-blocking send. When the socket write buffer limit is reached, we should stop trying to send and wait for the socket to become writable again. Non-blocking TCP sockets can return in two different ways when the write buffer limit is reached: 1. ret = -1 and errno = EAGAIN/EWOULDBLOCK. No data has been written. 2. ret < total_size. Short write, only part of the message was transmitted. Handle both cases and keep track of how many bytes have been written in s->send_index. (This includes the 'length' header before the actual payload buffer.) Signed-off-by: Stefan Hajnoczi <stefanha@linux.vnet.ibm.com> |
