We now reset the THD members related to auto_increment+binlog in MYSQL_LOG::write(). This is better than in THD::cleanup_after_query(), which was not able to distinguish between SELECT myfunc1(),myfunc2() and INSERT INTO t SELECT myfunc1(),myfunc2() from a binlogging point of view. Rows_log_event::exec_event() now calls lex_start() instead of mysql_init_query() because the latter now does too much (it resets the binlog format). mysql-test/extra/rpl_tests/rpl_insert_id.test: fix after merge mysql-test/mysql-test-run.pl: -v does not bring useful information when running valgrind; I remove it; if you think it's useful add it back. mysql-test/r/binlog_stm_mix_innodb_myisam.result: Position columns of SHOW BINLOG EVENTS are replaced by # (more robust if the size of an event changes). mysql-test/r/rpl_insert_id.result: fix after merge mysql-test/r/rpl_loaddata.result: The binlog positions change, because one event disappeared; indeed there was this in the binlog (in the current 5.1!): SET INSERT_ID=2; SET INSERT_ID=1; SET TIMESTAMP=1152540671; load data LOCAL INFILE '/tmp/SQL_LOAD_MB-1-2' INTO table t1; Two INSERT_ID events, useless and a bug. Goes away afer cleaning up auto_increment handling. mysql-test/r/rpl_switch_stm_row_mixed.result: INSERT_ID=5 appears, it's a consequence of having merged the fix for BUG#20341 "stored function inserting into one auto_increment puts bad data in slave". In mixed mode, if one substatement of a stored procedure requires row-based, the entire procedure uses row-based (was already true for stored functions); this is a consequence of not doing the resetting of binlog format inside lock_tables() (which didn't work with how the slave thread executes row-based binlog events). mysql-test/t/rpl_switch_stm_row_mixed.test: removing the multi-row delayed insert because in RBR the number of events which it generates, is not repeatable (probably depends on how the delayed thread groups rows, i.e. dependent on timing). sql/ha_partition.cc: update to new prototype sql/ha_partition.h: update to new prototype of the handler:: method. sql/handler.cc: after-merge fixes (manually merging part which was hard to merge in fmtool) sql/log.cc: When we write to the binary log, THD's parameters which influenced this write are reset: stmt_depends_on_first_successful_insert_id_in_prev_stmt and auto_inc_intervals_in_cur_stmt_for_binlog. This is so that future writes are not influenced by those and can write their own values. As a consequence, when we don't write to the binlog we do not reset. This is to abide by the rule that in a complex statement (using triggers etc), the first top- or substatement to generate auto_increment ids wins their writing to the binlog (that writing may be done by the statement itself or by the caller); so for example for INSERT INTO t SELECT myfunc() where myfunc() inserts into auto_increment and INSERT INTO t does not, myfunc() will fill auto_inc_intervals_in_cur_stmt_for_binlog, which will not be reset when myfunc() ends, then INSERT INTO t will write to the binlog and thus write the preserved auto_inc_intervals_in_cur_stmt_for_binlog. sql/log_event.cc: mysql_init_query() does too much now to be called in Rows_log_event::exec_event (it call mysql_reset_thd_for_next_command() which may switch the binlog format now). It's ok to call it in Table_map_log_event::exec_event() but its call must be before setting the binlog format to "row". sql/sql_base.cc: Resetting the binlog format in lock_tables() was a bad idea of mine; it causes problems in execution of row-based binlog events, where the thread sets the binlog format by itself and does not want a next lock_tables() to reset the binlog format. It is also misleading, for a function named lock_tables(), to reset the binlog format. As a consequence of this change, in mixed binlogging mode, a routine is logged either entirely statement-based or entirely row-based, we don't switch in the middle (this was already true for prelocked routines, now it's also true for stored procedures). sql/sql_class.cc: resetting of auto_increment variables used for binlogging is now done when writing to the binary log, no need to do the resetting at the end of the statement. It is also more correct this way; consider SELECT myfunc1(),myfunc2(); where both functions insert into the same auto_increment column. Binlogging is done in 2 events: "SELECT myfunc1()" and "SELECT myfunc2()". So each of those needs to have, in binlog, the INSERT_ID which it inserted. But as the 2 function calls are executed under prelocked mode, the old code didn't reset auto_inc_intervals_in_cur_stmt_for_binlog after the first SELECT was binlogged, and so the INSERT_ID of the first SELECT was binlogged for the first SELECT and (wrong) also for the 2nd SELECT event. stmt_depends_on_first_... has the same logic. sql/sql_class.h: clearer comment sql/sql_delete.cc: unneeded #ifdef. As we temporarily change the binlog format to "statement" before calling mysql_delete(), we must restore it afterwards. sql/sql_insert.cc: after-merge fixes. No need to reset auto_inc_intervals_in_cur_stmt_for_binlog for every row in the delayed insert system thread, because we already reset it when writing to the binlog. sql/sql_parse.cc: unneeded #ifdef
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
