Semi-sync uses an extra connection from slave to master to send replies, this is a normal client connection, and used a normal SET query to set the reply information on master, which is visible to user and may cause some confusion and complaining. This problem is fixed by using the method of sending reply by using the same connection that is used by master dump thread to send binlog to slave. Since now the semi-sync plugins are integrated with the server code, it is not a problem to use the internal net interfaces to do this. The master dump thread will mark the event requires a reply and wait for the reply when the event just sent is the last event of a transaction and semi-sync status is ON; And the slave will send a reply to master when it received such an event that requires a reply.
