We should not allow explicit or implicit transaction commits inside of stored functions or triggers (so in autocommit mode we should not do commits after execution of sub-statement). Also since we don't support nested statement transactions in 5.0, we shouldn't commit or rollback stmt transactions while we are inside stored functions or triggers. This should be fixed in later (>=5.1) releases. mysql-test/r/sp_trans.result: Added test for bug #10015 "Crash in InnoDB if stored routines are used" and for general transaction handling inside of functions. mysql-test/t/sp_trans.test: Added test for bug #10015 "Crash in InnoDB if stored routines are used" and for general transaction handling inside of functions. sql/handler.cc: ha_trans_commit()/ha_trans_rollback(): Since we don't support nested statement transactions in 5.0, we can't commit or rollback stmt transactions while we are inside stored functions or triggers. So we simply do nothing now. This should be fixed in later ( >= 5.1) releases. sql/item_func.cc: Item_func_sp::execute(): Set THD::transaction.in_sub_stmt flag to TRUE during stored function execution to prevent commits and rollbacks for statement level transactions, since doing them will ruin such transaction for stateemtn which calls this function. sql/share/errmsg.txt: Added error message which says that statements doing explicit or implicit commits are disallowed in triggers and stored functions. sql/sql_base.cc: close_thread_tables(): Clarified comment about committing of statement transactions in prelocked mode. sql/sql_class.h: THD::transaction: Added in_sub_stmt method which indicates that we are executing statements from trigger or stored function now, and thus statement transaction belongs to statement which invoked this routine and we should not commit or rollback it while executing these sub-statements. sql/sql_parse.cc: end_active_trans()/begin_trans()/end_trans(): We should not commit or rollback global (non-stmt) transaction if we are executing stored function or trigger. These checks will catch situation when we are trying to do commit or rollback in stored procedure which is called from function or trigger. sql/sql_trigger.h: Table_triggers_list::process_triggers(): Set THD::transaction.in_sub_stmt flag to TRUE during trigger execution to prevent commits and rollbacks for statement level transactions, since doing them will ruin such transaction for stateemtn which invokes this trigger. sql/sql_yacc.yy: Prohibited usage of statements which do explicit or implicit commit or rollback inside of stored functions and triggers.
This directory contains a test suite for mysql daemon. To run the currently existing test cases, simply execute ./mysql-test-run in this directory. It will fire up the newly built mysqld and test it. If you want to run the test with a running MySQL server use the --external option to mysql-test-run. Note that you do not have to have to do make install, and you could actually have a co-existing MySQL installation - the tests will not conflict with it. All tests must pass. If one or more of them fail on your system, please read the following manual section of how to report the problem: http://dev.mysql.com/doc/mysql/en/MySQL_test_suite.html You can create your own test cases. To create a test case: xemacs t/test_case_name.test in the file, put a set of SQL commands that will create some tables, load test data, run some queries to manipulate it. We would appreciate if the test tables were called t1, t2, t3 ... (to not conflict too much with existing tables). Your test should begin by dropping the tables you are going to create and end by dropping them again. This will ensure that one can run the test over and over again. If you are using mysqltest commands (like result file names) in your test case you should do create the result file as follows: mysql-test-run --record test_case_name or mysqltest --record < t/test_case_name.test If you only have a simple test cases consistent of SQL commands and comments you can create the test case one of the following ways: mysql-test-run --record test_case_name mysql test < t/test_case_name.test > r/test_case_name.result mysqltest --record --record-file=r/test_case_name.result < t/test_case_name.test When this is done, take a look at r/test_case_name.result - If the result is wrong, you have found a bug; In this case you should edit the test result to the correct results so that we can verify that the bug is corrected in future releases. To submit your test case, put your .test file and .result file(s) into a tar.gz archive, add a README that explains the problem, ftp the archive to ftp://support.mysql.com/pub/mysql/secret/ and send a mail to bugs@lists.mysql.com
