This patch adds the ability to store extra field metadata in the table map event. This data can include pack_length() or field_lenght() for fields such as CHAR or VARCHAR enabling developers to add code that can check for compatibilty between master and slave columns. More importantly, the extra field metadata can be used to store data from the master correctly should a VARCHAR field on the master be <= 255 bytes while the same field on the slave is > 255 bytes. The patch also includes the needed changes to unpack to ensure that data which is smaller on the master can be unpacked correctly on the slave. WL#3915 : (NDB) master's cols > slave Slave starts accepting and handling rows of master's tables which have more columns. The most important part of implementation is how to caclulate the amount of bytes to skip for unknown by slave column. mysql-test/suite/binlog/t/binlog_row_mix_innodb_myisam.test: WL#3228 : RBR using different table defs on slave/master This patch changes the test to coincide with changes to binlog size of table map event. mysql-test/suite/rpl/r/rpl_row_basic_11bugs.result: WL#3228 : RBR using different table defs on slave/master This patch contains a new result file as a result of the change to the size of the tablemap log event. mysql-test/suite/rpl/r/rpl_row_create_table.result: WL#3228 : RBR using different table defs on slave/master This patch contains a new result file as a result of the change to the size of the tablemap log event. mysql-test/suite/rpl/r/rpl_row_flsh_tbls.result: WL#3228 : RBR using different table defs on slave/master This patch contains a new result file as a result of the change to the size of the tablemap log event. mysql-test/suite/rpl/r/rpl_row_inexist_tbl.result: WL#3228 : RBR using different table defs on slave/master This patch contains a new result file as a result of the change to the size of the tablemap log event. mysql-test/suite/rpl/r/rpl_row_log.result: WL#3228 : RBR using different table defs on slave/master This patch contains a new result file as a result of the change to the size of the tablemap log event. mysql-test/suite/rpl/r/rpl_row_log_innodb.result: WL#3228 : RBR using different table defs on slave/master This patch contains a new result file as a result of the change to the size of the tablemap log event. mysql-test/suite/rpl/r/rpl_row_max_relay_size.result: WL#3228 : RBR using different table defs on slave/master This patch contains a new result file as a result of the change to the size of the tablemap log event. mysql-test/suite/rpl/r/rpl_row_tabledefs_2myisam.result: WL#3228 : RBR using different table defs on slave/master This patch contains a new result file as a result of the change to the size of the tablemap log event. mysql-test/suite/rpl/r/rpl_row_tabledefs_3innodb.result: WL#3228 : RBR using different table defs on slave/master This patch contains a new result file as a result of the change to the size of the tablemap log event. mysql-test/suite/rpl/r/rpl_row_until.result: WL#3228 : RBR using different table defs on slave/master This patch contains a new result file as a result of the change to the size of the tablemap log event. mysql-test/suite/rpl/r/rpl_skip_error.result: WL#3228 : RBR using different table defs on slave/master This patch contains a new result file as a result of the change to the size of the tablemap log event. mysql-test/suite/rpl/t/disabled.def: WL#3915 master's cols > slave Disabled the rpl_stm_extraColmaster_ndb test because statement-based replication is not supported in NDB at this time. It can be enabled when statement-based replication for NDB is released. mysql-test/suite/rpl/t/rpl_row_create_table.test: WL#3228 : RBR using different table defs on slave/master This patch corrects binlog positions a result of the change to the size of the tablemap log event. mysql-test/suite/rpl/t/rpl_row_flsh_tbls.test: WL#3228 : RBR using different table defs on slave/master This patch corrects binlog positions a result of the change to the size of the tablemap log event. mysql-test/suite/rpl_ndb/r/rpl_ndb_log.result: WL#3228 : RBR using different table defs on slave/master This patch contains a new result file as a result of the change to the size of the tablemap log event. mysql-test/suite/rpl_ndb/r/rpl_truncate_7ndb.result: WL#3228 : RBR using different table defs on slave/master This patch contains a new result file as a result of the change to the size of the tablemap log event. sql/field.cc: WL#3228 : RBR using different table defs on slave/master This patch includes updates to the unpack() methods for the variable length fields. A new parameter was added (from_length) that is the value stored in the field_metadata of the table map from the table_def class. If the value is non-zero and less than what the field on the slave is then use the from_length else use the original value from the field on the slave. sql/field.h: L#3228 : RBR using different table defs on slave/master This patch includes updates to the unpack() methods for the variable length fields. A new parameter was added (from_length) that is the value stored in the field_metadata of the table map from the table_def class. sql/log_event.cc: WL#3228 : RBR using different table defs on slave/master This patch adds methods to calculate the field metadata size, prepare the field metadata for writing to the binlog, and additions to the Table_map_log_event::write_body method to include the field metadata in the table map that is written to the binlog. WL#3915 master's cols > slave copying extra (slave's) fields returns early if master's table version is wider; removing assert in the way of master > slave cols. sql/log_event.h: WL#3228 : RBR using different table defs on slave/master This patch adds method declarations and variables needed to support storing field metadata in the table map that is written to the binlog. sql/rpl_record.cc: WL#3228 : RBR using different table defs on slave/master This patch modifies the unpack_row() method to unpack fields passing in the value from the table_def class. This value is the extra field metadata stored there from the master. WL#3915 master's cols > slave adding a snippet that shift exectution curson donw the row skipping unknown by slave fields' data. sql/rpl_rli.h: WL#3228 : RBR using different table defs on slave/master This patch adds a helper function to retrieve the table_def for a given table in the RPL_TABLE_LIST structure. sql/rpl_utility.cc: WL#3228 : RBR using different table defs on slave/master This patch adds a helper method that retrieves the correct size parameter for the field. This method is used to compare the size as sent by the master with that on the slave for all types of fields that can vary in size and storage requirements. WL#3915 master's cols > slave Remove warning message for master's cols > slave. sql/rpl_utility.h: WL#3228 : RBR using different table defs on slave/master This patch changes the table_def class constructor to pass in the raw data read from the table map and extract it into an array of dimension size (number of fields). It also adds a method to return the field metadata for any field. The method returns the data stored in the table map or 0 if no data was stored for that field. Lastly, a method to return the results of field->maybe_null() is included so that the slave can determine if a field that is not on the slave is null. mysql-test/suite/rpl/t/rpl_colSize.test: WL#3228 : RBR using different table defs on slave/master This patch contains a new test designed to test the feature of having columns on the master that are smaller than what is on the slave. mysql-test/suite/rpl/t/rpl_extraColmaster_innodb-master.opt: WL#3915 master's cols > slave option for innodb mysql-test/suite/rpl/t/rpl_extraColmaster_innodb-slave.opt: WL#3915 master's cols > slave option for innodb mysql-test/suite/rpl/t/rpl_extraColmaster_innodb.test: WL#3915 master's cols > slave Test of innodb.

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
