################################################################################ # # BUG#22305605 STOP SLAVE IO THREAD PRINTS WRONG LOST CONNECTION MESSAGE # IN ERROR LOG FILE. # Problem: # STOP SLAVE IO_THREAD closes socket communication between Master and Slave. # This prints an ERROR message in the error log # [ERROR] Error reading packet from server: Lost connection to MySQL server # during query (server_errno=2013). # Here the socket closed intentionally by the DBA using command 'STOP SLAVE IO_THREAD'. # Hence no need to print the message [ERROR] that says "Lost connection" which will # confusion the users/DBAs. # Steps to Reproduce: # 1) Execute some dummy statements to make sure replication is working fine. # 2) Stop I/O thread and see that there is no panic message printed in log file. # 3) Stop SQL thread and see that there is no panic message printed in log file. # 4) Stop both I/O and SQL threads and see that there is no panic message printed # in log file. # ################################################################################ --source include/master-slave.inc # Execute dummy statements on Master and sync with Slave.
