# # ==== Purpose ==== # # This test checks if the variable Slave_open_temp_tables is set # to the correct number of temporary tables open in the slave and if # the corresponding warning is correctly issued. # # ==== Implementation ==== # A temporary table is first created. The slave replication thread is # stopped so that the corresponding warning is generated. Finally, the # temporary table is dropped to verify that the number of open tables # decreased to zero and, consequently, that no warning is issued when # stopping the slave's replication thread again. # # # ==== References ==== # # Bug#21357008: SLAVE_OPEN_TEMP_TABLES WRONG AFTER RESET SLAVE WHEN # USING MULTI-SOURCE --source include/have_binlog_format_mixed.inc --source include/master-slave.inc # Create temporary table.
