The reason for the bug was that replaying of a query on slave could not be possible since its event was recorded with the killed error. Due to the specific of handling INSERT, which per-row-while-loop is unbreakable to killing, the query on transactional table should have not appeared in binlog unless there was a call to a stored routine that got interrupted with killing (and then there must be an error returned out of the loop). The offered solution added the following rule for binlogging of INSERT that accounts the above specifics: For INSERT on transactional-table if the error was not set the only raised flag is harmless and is ignored via masking out on time of creation of binlog event. For both table types the combination of raised error and KILLED flag indicates that there was potentially partial execution on master and consistency is under the question. In that case the code continues to binlog an event with an appropriate killed error. The fix relies on the specified behaviour of stored routine that must propagate the error to the top level query handling if the thd->killed flag was raised in the routine execution. The patch adds an arg with the default killed-status-unset value to Query_log_event::Query_log_event. sql/log_event.cc: killed_status as the value of thd->killed can be passed as an arg to the constructor. if the value is different from the default the arg is set to the current thd->killed value. A caller might need to masquerade thd->killed with THD::NOT_KILLED. So far only mysql_insert() uses such explicit way to tell the constructor about killing status. sql/log_event.h: default arg to the constructor with meaning of killed status of the query. if the arg is not explicitly provided the status of thd->killed will be snapshot inside of the constuctor, which is potentially incorrect (see bug#27571) sql/sql_class.h: extending killed_state with no-state member. sql/sql_insert.cc: ignore the KILLED flag incl KILL_BAD_DATA when the INSERT query event is created without an `error'; sql/sql_update.cc: Suggestion how to fix bug#27571 as comments. mysql-test/r/binlog_killed.result: new result file mysql-test/t/binlog_killed.test: regression tests also apply for bug27563, BUG#27565
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
