# ==== Purpose ==== # # When mysqlbinlog connects to a running server it uses the client command # COM_BINLOG_DUMP, and this command has a flag called BINLOG_DUMP_NON_BLOCK # which instructs the server to stop sending when it reaches the end of the # binary log. # # # There are two ways provided by the server to set the non-blocking behavior. # 1) Setting the connection-server-id=0. (this is the default value of # connection-server-id) # 2) Setting BINLOG_DUMP_NON_BLOCK flag # --To test this, we set connection-server-id to some value other then zero # and not calling stop-never option in mysqlbinlog # # ==== Bug and Worklog references ==== # # BUG##18000079 - binlog_dump_non_block disappeared in mysql 5.6 # - Created the test to verify the bugfix. # # ==== Implementation ==== --source include/not_gtid_enabled.inc # connection-server-id is a debug option.
