heartbeat messages are sent to keep a connection active. However, a heartbeat messages was sent periodically, even if some other messages were sent during this period. It is not an issue but it is useless. heartbeat messages should only be sent if nothing was sent to the peer since a moment. So, in this patch, the heartbeat timer is rearmed each time a message is sent. On the receiver side, the reconnect timer was only rearmed when a heartbeat message was received instead of rearming it for any messages. Again, it is not an issue because the inactivity is managed with PEER_F_ALIVE flag. This flag is removed when the reconnect timer timed out but it is reinserted when something is received. But an periodic wakeup may be uselessly performed. So, in this patch, the reconnect timer is rearmed each time a message is received. |
