on CREATE TABLE .. SELECT I_S.PART This assert was triggered if an InnoDB table was created using CREATE TABLE ... AS SELECT where the query used an I_S table, and a view existed in the database. It would also be triggered for any statement changing an InnoDB table (e.g. INSERT, UPDATE, DELETE) which had a subquery referencing an I_S table. The assert was triggered if open_normal_and_derived_tables() failed and a statement transaction had been started. This will usually not happen as tables are opened before a statement transaction is started. However, e.g. CREATE TABLE ... AS SELECT starts a transaction in order to insert tuples into the new table. And if the subquery references an I_S table, all current tables and views can be opened in order to fill the I_S table on the fly. If a view is discovered, open will fail as it is instructed to open tables only (OPEN_TABLE_ONLY). This would cause the assert to be triggered. The assert was added in the patch for Bug#52044 and was therefore not in any released versions of the server. This patch fixes the problem by adjusting the assert to take into consideration the possibility of tables being opened as part of an I_S query. This is similar to what is already done for close_tables_for_reopen(). Test case added to information_schema_inno.test. |

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
