BUG#12359942 - REPLICATION TEST FROM ENGINE SUITE RPL_ROW_UNTIL TIMES OUT
=== Problem === The test is dependent on binlog positions and checks to see if the command 'START SLAVE' functions correctly with the 'UNTIL' clause added to it. The 'UNTIL' clause is added to specify that the slave should start and run until the SQL thread reaches a given point in the master binary log or in the slave relay log. The test uses hard coded values for MASTER_LOG_POS and RELAY_LOG_POS, instead of extracting it using query_get_value() function. There is a test 'rpl.rpl_row_until' which does the similar thing but uses query_get_value() function to set the values of MASTER_LOG_POS/ RELAY_LOG_POS. To be precise, rpl.rpl_row_until is a modified version of engines/func.rpl_row_until.test. The use of hard coded values may lead the slave to stop at a position which may differ from the expected position in the binlog file, an example being the failure of engines/funcs.rpl_row_until in mysql-5.1 given as: "query 'select * from t2' failed. Table 'test.t2' doesn't exist". In this case, the slave actually ran a couple of extra commands as a result of which the slave first deleted the table and then ran a select query on table, leading to the above mentioned failure. === Fix === 1) Fixed the code for failure seen in rpl.rpl_row_until. This test was also failing although the symptoms of failure were different. 2) Copied the contents from rpl.rpl_row_until into into engines/funcs.rpl.rpl_row_until. 3) Updated engines/funcs.rpl_row_until.result accordingly.
