Master (no AUTOCOMMIT!): INSERT INTO mysqltest1.t1 without commit # 2. Master and slave: Check the content of mysqltest1.t1 # 3. Master (no AUTOCOMMIT!): EXECUTE the statement to be tested # 4. Master and slave: Check the content of mysqltest1.t1 # 5. Master (no AUTOCOMMIT!): ROLLBACK # 6. Master and slave: Check the content of mysqltest1.t1 # If the previous into mysqltest1.t1 inserted row is visible, # than the statement to be tested caused an explicit COMMIT # (statement = COMMIT) or an implicit COMMIT (example CREATE TABLE). # If the previous into mysqltest1.t1 inserted row is not visible, # than the statement to be tested caused either an explicit ROLLBACK # (statement = ROLLBACK), an implicit ROLLBACK (deadlock etc. but # not tested here) or it does not cause any transaction end. # 7. Flush the logs # # Some rules: # ----------- # 1. Any use of mysqltest1.t1 within the statement to be tested must be # avoided if possible. The only known exception is around LOCK TABLE. # # 2. The test logics needs for # master connection: AUTOCOMMIT = 0 # slave connection: AUTOCOMMIT = 1 # The master connection is the actor and the slave connection is # only an observer. I.e. the slave connection must not influence # the activities of master connection. # # 3. !All! objects to be dropped, renamed, altered ... must be created # before the tests start. # --> less switching of AUTOCOMMIT mode on master side. # # 4. Never use a test object, which was direct or indirect affected by a # preceeding test sequence again. # If one preceeding test sequence hits a (sometimes not visible, # because the sql error code of the statement might be 0) bug # and these rules are ignored, a following test sequence might earn ugly # effects like failing 'sync_slave_with_master', crashes of the slave or # abort of the test case etc.. This means during analysis the first look # points into a totally wrong area. # Except table mysqltest1.t1 where ONLY DML is allowed. # # 5. This file is used in several tests (t/rpl_ddl_<whatever>.test). # Please be aware that every change of the current file affects # the results of these tests. # # ML: Some maybe banal hints: # 1. The fact that we have here a master - slave replication does # not cause that many general MySQL properties do not apply. # Example: # The connection to the slave is just a simple session and not a however # magic working "copy" of the master session or something similar. # - TEMPORARY TABLES and @variables are session specific # - the slave session cannot see these things of the master. # 2. The slave connection must not call sync_slave_with_master. # 3. SHOW STATUS SLAVE must be run within the slave connection. # 4. Testcase analysis becomes much more comfortable if # $show_binlog within include/rpl_stmt_seq.inc is set to 1. # ############################################################### # Some preparations ############################################################### # The sync_slave_with_master is needed to make the xids deterministic. --source include/sync_slave_sql_with_master.inc --echo --echo -------- switch to master ------- connection master; SET AUTOCOMMIT = 1; # # 2.
