in short we now record whenever the slave I/O thread ignores a master's event because of its server id, and use this info in the slave SQL thread to advance Exec_master_log_pos. Because if we do not, this variable stays at the position of the last executed event, i.e. the last *non-ignored* executed one, which may not be the last of the master's binlog (and so the slave *looks* behind the master though it's data-wise it's not). mysql-test/t/rpl_dual_pos_advance-master.opt: empty; its goal is just to trigger a server restart after running the test, so that the master forgets that it was a slave (otherwise it affects the following tests). sql/log.cc: No more default arguments for Rotate_log_event constructor. MYSQL_LOG::appendv() is now called without mutex. sql/log_event.cc: Moving one Rotate_log_event constructor from log_event.h. Support for on-demand choice of duplicating the string argument of the constructor or not (because there now are needs for both alternatives, see slave.cc). sql/log_event.h: We now have a case where a Rotate_log_event is executed by the slave SQL thread while not being in the relay log, so it needs to pretend its length is 0: a ZERO_LEN flag for that; a flag DUP_NAME (replaces "bool alloced") to be able to choose if we want the constructor to duplicate the string argument or not. sql/slave.cc: A comment for BUG#13861 (to be fixed). llstr() instead of %ld as the number is ulonglong. mi->rli becomes rli in some places. Fix for BUG#13023: - in the slave I/O thread, whenever we ignore an event because of its server id we update a couple of coordinates in memory - in the slave SQL thread, whenever we bump into the end of the latest relay log, we check this couple of coordinates to see if we should advance our Exec_master_log_pos. - when the slave I/O thread terminates it saves these in-memory coordinates into a Rotate event in the relay log, so that they are durable. sql/slave.h: A couple of coordinates in RELAY_LOG_INFO to keep track of the last ignored events received by the slave I/O thread (ignored because of the server id). mysql-test/r/rpl_dual_pos_advance.result: New BitKeeper file ``mysql-test/r/rpl_dual_pos_advance.result'' mysql-test/t/rpl_dual_pos_advance.test: Test for BUG#13023 (with a part, disabled, to test BUG#13861 when I fix it). Before the fix, this test used to hang. |

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
