After review version. Added a condition for MERGE tables. These do not have unique indexes. But every key could be a unique key on the underlying MyISAM table. So get the maximum key length for MERGE tables instead of the maximum unique key length. This is used for buffer allocation in write_record(). mysql-test/r/merge.result: Bug#10400 - Improperly-defined MERGE table crashes with INSERT ... ON DUPLICATE KEY UPDATE The test result. mysql-test/t/merge.test: Bug#10400 - Improperly-defined MERGE table crashes with INSERT ... ON DUPLICATE KEY UPDATE The test case does not in all cases show the problem without the bugfix. The improper memory allocation might get through undetected in many cases. sql/ha_myisammrg.h: Bug#10400 - Improperly-defined MERGE table crashes with INSERT ... ON DUPLICATE KEY UPDATE Set a table_flag for the MERGE engine telling that any index might be unique without being specified as such. sql/handler.h: Bug#10400 - Improperly-defined MERGE table crashes with INSERT ... ON DUPLICATE KEY UPDATE Added a new table_flag telling that any index might be unique without being specified as such. sql/sql_insert.cc: Bug#10400 - Improperly-defined MERGE table crashes with INSERT ... ON DUPLICATE KEY UPDATE Changed the freeing of the memory to be symmetric to its allocation (my_safe_alloc -> my_safe_afree). This is not directly related to the bug. sql/table.cc: Bug#10400 - Improperly-defined MERGE table crashes with INSERT ... ON DUPLICATE KEY UPDATE Added a condition for MERGE tables. These do not have unique indexes. But every key could be a unique key on the underlying MyISAM table. So get the maximum key length for MERGE tables instead of the maximum unique key length. This is used for buffer allocation in write_record(). |

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 the test with a running MySQL server use the --external option to mysql-test-run. 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
