* Preparation for having a background checkpoint thread: frequency of checkpoint taken by that thread is now configurable by the user: global variable maria_checkpoint_frequency, in seconds, default 30 (checkpoint every 30th second); 0 means no checkpoints (and thus no background thread, thus no background flushing, that will probably only be used for testing). * Don't take checkpoints in Recovery if it didn't do anything significant; thus no checkpoint after a clean shutdown/restart. The only checkpoint which is never skipped is the one at shutdown. * fix for a test failure (after-merge fix) include/maria.h: new variable mysql-test/suite/rpl/r/rpl_row_flsh_tbls.result: result update mysql-test/suite/rpl/t/rpl_row_flsh_tbls.test: position update (=after merge fix, as this position was already changed into 5.1 and not merged here, causing test to fail) storage/maria/ha_maria.cc: Checkpoint's frequency is now configurable by the user: global variable maria_checkpoint_frequency. Changing it on the fly requires us to shutdown/restart the background checkpoint thread, as the loop done in that thread assumes a constant checkpoint interval. Default value is 30: a checkpoint every 30 seconds (yes, I know, physicists will remind that it should be named "period" then). ha_maria now asks for a background checkpoint thread when it starts, but this is still overruled (disabled) in ma_checkpoint_init(). storage/maria/ma_checkpoint.c: Checkpoint's frequency is now configurable by the user: background thread takes a checkpoint every maria_checkpoint_interval-th second. If that variable is 0, no checkpoints are taken. Note, I will enable the background thread only in a later changeset. storage/maria/ma_recovery.c: Don't take checkpoints at the end of the REDO phase and at the end of Recovery if Recovery didn't make anything significant (didn't open any tables, didn't rollback any transactions). With this, after a clean shutdown, Recovery shouldn't take any checkpoint, which makes starting faster (we save a few fsync()s of the log and control file). |

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
