This allows us to use statement replication with functions and triggers The following things are fixed with this patch: - NOW() and automatic timestamps takes the value from the main event for functions and triggers (which allows these to replicate with statement level logging) - No side effects for triggers or functions with auto-increment values(), last_insert_id(), rand() or found_rows() - Triggers can't return result sets Fixes bugs: #12480: NOW() is not constant in a trigger #12481: Using NOW() in a stored function breaks statement based replication #12482: Triggers has side effects with auto_increment values #11587: trigger causes lost connection error mysql-test/r/trigger.result: Added test fpr big mysql-test/t/sp-error.test: Changed error message numbers mysql-test/t/trigger.test: Added test for trigger returning result (#11587) sql/item_func.cc: Store the first used seed value for RAND() value. (This makes rand() replicatable in functions and triggers) Save and clear run context before executing a stored function and restore it afterwards. This removes side effects of stored functions for RAND(), auto-increment values and NOW() and makes most stored function replicatable sql/share/errmsg.txt: Reuse error message also for triggers sql/sp_head.cc: If in function or trigger, don't change value of NOW() (This allows us to use statement replication with functions that directly or indirectly uses timestamps) sql/sql_class.cc: Added framework for storing and retrieving run context while exceuting triggers or stored functions. sql/sql_class.h: Added framework for storing and retrieving run context while exceuting triggers or stored functions. sql/sql_parse.cc: If in function or trigger, don't change value of NOW() (This allows us to use statement replication with functions that directly or indirectly uses timestamps) sql/sql_trigger.cc: Moved process_triggers function from sql_trigger.h Use reset/restore sub_statement_state while executing triggers to avoid side effects and make them replicatable sql/sql_trigger.h: Moved process_triggers function from sql_trigger.h Use reset/restore sub_statement_state while executing triggers to avoid side effects and make them replicatable sql/sql_yacc.yy: Give error message if trigger can return a result set (Bug #11587) tests/fork_big2.pl: Removed return from end of lines mysql-test/r/rpl_trigger.result: New BitKeeper file ``mysql-test/r/rpl_trigger.result'' mysql-test/t/rpl_trigger.test: New BitKeeper file ``mysql-test/t/rpl_trigger.test''
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 a test with a running MySQL server use the --extern option to mysql-test-run. Please note that in this mode the test suite expects user to specify test names to run. Otherwise it falls back to the normal "non-extern" behaviour. The reason is that some tests could not run with external server. Here is the sample command to test "alias" and "analyze" tests on external server: mysql-test-run --extern alias analyze To match your setup you might also need to provide --socket, --user and other relevant options. 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
