Several system variables did not behave like system variables should do. When trying to SET them or use them in SELECT, they were reported as "unknown system variable". But they appeared in SHOW VARIABLES. This has been fixed by removing the "fixed_vars" array of variables and integrating the variables into the normal system variables chain. All of these variables do now behave as read-only global-only variables. Trying to SET them tells they are read-only, trying to SELECT the session value tells they are global only. Selecting the global value works. It delivers the same value as SHOW VARIABLES. mysql-test/r/variables-notembedded.result: Bug#28234 - global/session scope - documentation vs implementation New test result. mysql-test/r/variables.result: Bug#28234 - global/session scope - documentation vs implementation New test result. mysql-test/t/variables-notembedded.test: Bug#28234 - global/session scope - documentation vs implementation Added a test for each moved variable that is not present in an embedded server. mysql-test/t/variables.test: Bug#28234 - global/session scope - documentation vs implementation Added a test for each moved variable that is also present in an embedded server. sql/item_func.cc: Bug#28234 - global/session scope - documentation vs implementation Added SHOW_BOOL to some Item_func_get_system_var methods. sql/set_var.cc: Bug#28234 - global/session scope - documentation vs implementation Moved all variables from the "fixed_vars" array into the normal system variables chain by using the new variable class sys_var_const. Removed the fixed_show_vars array and its initialization in enumerate_sys_vars(). Removed mysql_append_static_vars(), which added fixed_vars arrays to the fixed_show_vars array. sql/set_var.h: Bug#28234 - global/session scope - documentation vs implementation Added the new system variable class sys_var_const. Removed declaration of mysql_append_static_vars(). sql/slave.cc: Bug#28234 - global/session scope - documentation vs implementation Moved the definition of show_slave_skip_errors() from sql_repl.cc to here and renamed it to print_slave_skip_errors(). Changed print_slave_skip_errors() to create a static buffer with a printable version of the error numbers set. Added a call of print_slave_skip_errors() to init_slave_skip_errors(). sql/slave.h: Bug#28234 - global/session scope - documentation vs implementation Added declaration of slave_skip_error_names. sql/sql_repl.cc: Bug#28234 - global/session scope - documentation vs implementation Moved all variables from the "fixed_vars" array into the normal system variables chain by using the new variable class sys_var_const. Moved the definition of show_slave_skip_errors() to slave.cc and modified it to compute the string once at server initialization only. Removed the call to mysql_append_static_vars().
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
