=== 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. mysql-test/suite/engines/funcs/r/rpl_row_until.result: modified to accomodate the changes in corresponding test file. mysql-test/suite/engines/funcs/t/disabled.def: removed from the list of disabled tests. mysql-test/suite/engines/funcs/t/rpl_row_until.test: fixed rpl.rpl_row_until and copied its content to engines/funcs.rpl_row_until. The reason being both are same tests but rpl.rpl_row_until is an updated version. mysql-test/suite/rpl/t/disabled.def: removed from the list of disabled tests. sql/sql_repl.cc: Added a check to catch an improper combination of arguements passed to 'START SLAVE UNTIL'. Earlier, START SLAVE UNTIL MASTER_LOG_FILE='master-bin.000001', MASTER_LOG_POS=561, RELAY_LOG_POS=12; passed. It is now detected and an error is reported. |

This directory includes a set of three test suites aimed as testing functionality in an engine independent way, that is - the tests should work identically against different engines. The following suites are included: 1) 'funcs' suite ------------- A collection of functional tests covering basic engine and server functionality that can be run against iany engine. To run the test suite: cd INSTALL_DIR/mysql-test run: perl ./mysql-test-run.pl --suite=engines/funcs --mysqld=--default-storage-engine=<engine> 2) 'iuds' suite ------------ Similar to the above focused on insert/update/delete operations of different different data types. To run the test suite: cd INSTALL_DIR/mysql-test run: perl ./mysql-test-run.pl --suite=engines/iuds --mysqld=--default-storage-engine=<engine> 3) 'rr_trx' suite (transactional engines only) -------------- A scenario of multiple client connections verifying transactions with repeatable read isolation level To run the test suite with innodb: cd INSTALL_DIR/mysql-test run: perl ./suite/engines/rr_trx/run_stress_tx_rr.pl --engine=<engine> [--duration=<nn>] [--threads=<nn>] [--try] [--help] This test is can be run against any transactional engine. However scripts need to be modified in order to support such engines (current scripts support only InnoDB). In order to add support for a new engine, you will need to modify scripts as follows: 1) cd to INSTALL_DIR/mysql-test/suite/engines/rr_trx 2) Modify the 'run_stress_rr.pl' file by adding an 'elsif' section for your engine and have it include specific values required to be passed as startup parameters to the MySQL server by specifying them using "--mysqld" options (see InnoDB example). 3) Copy the 'init_innodb.txt' file to 'init_<engine>.txt file and change its content to be "init_<engine>". 4) In the 't' directory copy the "init_innodb.test" file to "init_<engine>.test" and change the value of the '$engine' variable to <engine>. 5) In the 'r' directory copy "the init_innodb.result" file to "init_<engine>.result" and change refrences to 'InnoDB' to <engine>. Known Issues ------------ 1) The folowing tests in the 'iuds' suite: - delete_decimal - insert_decimal - update_decimal will return a 'Warning 1264 - Out of range value...' warning if run in a 32-bit environment. Add the '--force' option to prevent the test run from aborting. 2) The following tests in the 'funcs' suite will fail when run against the innodb_plugin: - crash_manycolumns_string (bug 50495) - ix_unique_lob (bug 52056, masked by an 'Out of memory error' on some 32-bit platforms) - ix_unique_string_length (bug 52056, masked by an 'Out of memory error' on some 32-bit platforms) Add the '--force' option to prevent the test run from aborting. 3) Some of the rpl_xxx tests in the 'funcs' suite require a secific binlog_forat setting and will be skipped otherwise. 4) Some of the rpl_xxx tests in the 'funcs' suite will report a 'Statement unsafe for replication' warning when run againsr a server configured to use statement based replication.
