Before this change, the functions BENCHMARK, ENCODE, DECODE and FORMAT could only accept a constant for some parameters. After this change, this restriction has been removed. An implication is that these functions can also be used in prepared statements. The change consist of changing the following classes: - Item_func_benchmark - Item_func_encode - Item_func_decode - Item_func_format to: - only accept Item* in the constructor, - and evaluate arguments during calls to val_xxx() which fits the general design of all the other functions. The 'TODO' items identified in item_create.cc during the work done for Bug 21114 are addressed by this fix, as a natural consequence of aligning the design. In the 'func_str' test, a single very long test line involving an explain extended select with many functions has been rewritten into multiple separate tests, to improve maintainability. The result of explain extended select decode(encode(...)) has changed, since the encode and decode functions now print all their parameters. mysql-test/r/func_str.result: Bug#22684 (BENCHMARK, ENCODE, DECODE and FORMAT are not real functions) mysql-test/r/parser.result: Bug#22684 (BENCHMARK, ENCODE, DECODE and FORMAT are not real functions) mysql-test/r/ps.result: Bug#22684 (BENCHMARK, ENCODE, DECODE and FORMAT are not real functions) mysql-test/t/func_str.test: Bug#22684 (BENCHMARK, ENCODE, DECODE and FORMAT are not real functions) mysql-test/t/parser.test: Bug#22684 (BENCHMARK, ENCODE, DECODE and FORMAT are not real functions) mysql-test/t/ps.test: Bug#22684 (BENCHMARK, ENCODE, DECODE and FORMAT are not real functions) sql/item_create.cc: Bug#22684 (BENCHMARK, ENCODE, DECODE and FORMAT are not real functions) sql/item_func.cc: Bug#22684 (BENCHMARK, ENCODE, DECODE and FORMAT are not real functions) sql/item_func.h: Bug#22684 (BENCHMARK, ENCODE, DECODE and FORMAT are not real functions) sql/item_strfunc.cc: Bug#22684 (BENCHMARK, ENCODE, DECODE and FORMAT are not real functions) sql/item_strfunc.h: Bug#22684 (BENCHMARK, ENCODE, DECODE and FORMAT are not real functions)
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
