If [NOT] PRESERVE was not given, parser always defaulted to NOT PRESERVE, making it impossible for the "not given = no change" rule to work in ALTER EVENT. Leaving out the PRESERVE-clause defaults to NOT PRESERVE on CREATE now, and to "no change" in ALTER. mysql-test/r/events_2.result: show that giving no PRESERVE-clause to ALTER EVENT results in no change. show that giving no PRESERVE-clause to CREATE EVENT defaults to NOT PRESERVE as per the docs. Show specifically that this is also handled correctly when trying to ALTER EVENTs into the past. mysql-test/t/events_2.test: show that giving no PRESERVE-clause to ALTER EVENT results in no change. show that giving no PRESERVE-clause to CREATE EVENT defaults to NOT PRESERVE as per the docs. Show specifically that this is also handled correctly when trying to ALTER EVENTs into the past. sql/event_db_repository.cc: If ALTER EVENT was given no PRESERVE-clause (meaning "no change"), we don't know the previous PRESERVE-setting by the time we check the parse-data. If ALTER EVENT was given dates that are in the past, we don't know how to react, lacking the PRESERVE-setting. Heal this by running the check later when we have actually read the previous EVENT-data. sql/event_parse_data.cc: Change default for ON COMPLETION to indicate, "not specified." Also defer throwing errors when ALTER EVENT is given dates in the past but not PRESERVE-clause until we know the previous PRESERVE-value. sql/event_parse_data.h: Add third state for ON COMPLETION [NOT] PRESERVE (preserve, don't, not specified). Make check_dates() public so we can defer this check until deeper in the callstack where we have all the required data. sql/sql_yacc.yy: If CREATE EVENT is not given ON COMPLETION [NOT] PRESERVE, we default to NOT, as per the docs.
This directory contains a test suite for the 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. 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 for instructions on how to report the problem: http://dev.mysql.com/doc/mysql/en/mysql-test-suite.html If you want to use an already running MySQL server for specific tests, use the --extern option to mysql-test-run. Please note that in this mode, the test suite expects you to provide the names of the tests to run. For example, here is the command to run the "alias" and "analyze" tests with an external server: mysql-test-run --extern alias analyze To match your setup, you might also need to provide --socket, --user, and other relevant options. With no test cases named on the command line, mysql-test-run falls back to the normal "non-extern" behavior. The reason for this is that some tests cannot run with an external server. You can create your own test cases. To create a test case, create a new file in the t subdirectory using a text editor. The file should have a .test extension. For example: xemacs t/test_case_name.test In the file, put a set of SQL statements that create some tables, load test data, and run some queries to manipulate it. We would appreciate it if you name your test tables 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 ensures that you can run the test over and over again. If you are using mysqltest commands (like result file names) in your test case, you should 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 consisting of SQL statements and comments, you can create the test case in 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 incorrect, 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
