Write only one encryption key to the checkpoint page. Use 4 bytes of nonce. Encrypt more of each redo log block, only skipping the 4-byte field LOG_BLOCK_HDR_NO which the initialization vector is derived from. Issue notes, not warning messages for rewriting the redo log files. recv_recovery_from_checkpoint_finish(): Do not generate any redo log, because we must avoid that before rewriting the redo log files, or otherwise a crash during a redo log rewrite (removing or adding encryption) may end up making the database unrecoverable. Instead, do these tasks in innobase_start_or_create_for_mysql(). Issue a firm "Missing MLOG_CHECKPOINT" error message. Remove some unreachable code and duplicated error messages for log corruption. LOG_HEADER_FORMAT_ENCRYPTED: A flag for identifying an encrypted redo log format. log_group_t::is_encrypted(), log_t::is_encrypted(): Determine if the redo log is in encrypted format. recv_find_max_checkpoint(): Interpret LOG_HEADER_FORMAT_ENCRYPTED. srv_prepare_to_delete_redo_log_files(): Display NOTE messages about adding or removing encryption. Do not issue warnings for redo log resizing any more. innobase_start_or_create_for_mysql(): Rebuild the redo logs also when the encryption changes. innodb_log_checksums_func_update(): Always use the CRC-32C checksum if innodb_encrypt_log. If needed, issue a warning that innodb_encrypt_log implies innodb_log_checksums. log_group_write_buf(): Compute the checksum on the encrypted block contents, so that transmission errors or incomplete blocks can be detected without decrypting. Rewrite most of the redo log encryption code. Only remember one encryption key at a time (but remember up to 5 when upgrading from the MariaDB 10.1 format.)
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. To run the test suite in a source directory, you must do make first. 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: https://mariadb.com/kb/en/reporting-bugs 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 socket=/tmp/mysql.sock 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 --database test --result-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. If you want to submit your test case you can send it to maria-developers@lists.launchpad.com or attach it to a bug report on http://mariadb.org/jira/. If the test case is really big or if it contains 'not public' data, then 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://ftp.askmonty.org/private and submit a report to http://mariadb.org/jira about it.
