from log): When row-based logging is used, the CREATE-SELECT is written as two parts: as a CREATE TABLE statement and as the rows for the table. For both transactional and non-transactional tables, the CREATE TABLE statement was written to the transaction cache, as were the rows, and on statement end, the entire transaction cache was written to the binary log if the table was non-transactional. For transactional tables, the events were kept in the transaction cache until end of transaction (or statement that were not part of a transaction). For the case when AUTOCOMMIT=0 and we are creating a transactional table using a create select, we would then keep the CREATE TABLE statement and the rows for the CREATE-SELECT, while executing the following statements. On a rollback, the transaction cache would then be cleared, which would also remove the CREATE TABLE statement. Hence no table would be created on the slave, while there is an empty table on the master. This relates to BUG#22865 where the table being created exists on the master, but not on the slave during insertion of rows into the newly created table. This occurs since the CREATE TABLE statement were still in the transaction cache until the statement finished executing, and possibly longer if the table was transactional. This patch changes the behaviour of the CREATE-SELECT statement by adding an implicit commit at the end of the statement when creating non-temporary tables. Hence, non-temporary tables will be written to the binary log on completion, and in the even of AUTOCOMMIT=0, a new transaction will be started. Temporary tables do not commit an ongoing transaction: neither as a pre- not a post-commit. The events for both transactional and non-transactional tables are saved in the transaction cache, and written to the binary log at end of the statement. |

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
