WL#3228 (NDB) : RBR using different table defs on slave/master 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 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.

WL#5151: Conversion between different types when replicating Row-based replication requires the types of columns on the master and slave to be approximately the same (some safe conversions between strings are allowed), but does not allow safe conversions between fields of similar types such as TINYINT and INT. This patch implement type conversions between similar fields on the master and slave. The conversions are controlled using a new variable SLAVE_TYPE_CONVERSIONS of type SET('ALL_LOSSY','ALL_NON_LOSSY'). Non-lossy conversions are any conversions that do not run the risk of losing any information, while lossy conversions can potentially truncate the value. The column definitions are checked to decide if the conversion is acceptable. If neither conversion is enabled, it is required that the definitions of the columns are identical on master and slave. Conversion is done by creating an internal conversion table, unpacking the master data into it, and then copy the data to the real table on the slave. .bzrignore: New files added client/Makefile.am: New files added client/mysqlbinlog.cc: Functions in rpl_utility.cc is now needed by mysqlbinlog.cc. libmysqld/Makefile.am: New files added mysql-test/extra/rpl_tests/check_type.inc: Test include file to check a single type conversion. mysql-test/extra/rpl_tests/rpl_extraSlave_Col.test: Switching to use INT instead of TEXT for column that should not have matching types. mysql-test/extra/rpl_tests/rpl_row_basic.test: Adding code to enable type conversions for BIT tests since InnoDB cannot handle them properly due to incorrect information stored as metadata. mysql-test/extra/rpl_tests/type_conversions.test: Test file to check a set of type conversions with current settings of slave_type_conversions. mysql-test/suite/rpl/t/rpl_typeconv.test: Test file to test conversions from master to slave with all possible values for slave_type_conversions. The test also checks that the slave_type_conversions variable works as expected. sql/field.cc: Changing definition of compatible_field_size to both check if two field with identical base types are compatible and give an order between them if they are compatible. This only implement checking on the slave, so it will not affect replication from an old master to a new slave. sql/field.h: Changing prototypes for functions: - compatible_field_size() - init_for_tmp_table() - row_pack_length() sql/log_event.cc: Changing compability checks to build a conversion table if the fields are compatible, but does not have the same base type. sql/log_event_old.cc: Changing compability checks to build a conversion table if the fields are compatible, but does not have the same base type. sql/mysql_priv.h: Adding global option variable for SLAVE_TYPE_CONVERSIONS sql/mysqld.cc: Adding SLAVE_TYPE_CONVERSIONS global server variable. sql/rpl_record.cc: Changing unpack_row to use the conversion table if present. sql/rpl_rli.h: Removing function get_tabledef and replacing it with get_table_data(). This function retrieve data for table opened for replication, not just table definition. sql/rpl_utility.cc: Function table_def::compatible_with is changed to compare table on master and slave for compatibility and generate a conversions table if they are compatible. Computing real type of fields from metadata for ENUM and SET types. Computing pack_length correctly for ENUM, SET, and BLOB types. Adding optimization to not check compatibility if no slave type conversions are enabled. sql/rpl_utility.h: Changing prototypes since implementation has changed. Modifying table_def::type() to return real type instead of stored type. sql/set_var.cc: Adding SLAVE_TYPE_CONVERSIONS variable. sql/set_var.h: Adding SLAVE_TYPE_CONVERSIONS variable. sql/share/errmsg.txt: Adding error messages for slave type conversions. sql/sql_class.h: Adding SLAVE_TYPE_CONVERSIONS variable. sql/sql_select.cc: Correcting create_virtual_tmp_table() to compute null bit positions correctly in the presence of bit fields.

WL#5151: Conversion between different types when replicating Row-based replication requires the types of columns on the master and slave to be approximately the same (some safe conversions between strings are allowed), but does not allow safe conversions between fields of similar types such as TINYINT and INT. This patch implement type conversions between similar fields on the master and slave. The conversions are controlled using a new variable SLAVE_TYPE_CONVERSIONS of type SET('ALL_LOSSY','ALL_NON_LOSSY'). Non-lossy conversions are any conversions that do not run the risk of losing any information, while lossy conversions can potentially truncate the value. The column definitions are checked to decide if the conversion is acceptable. If neither conversion is enabled, it is required that the definitions of the columns are identical on master and slave. Conversion is done by creating an internal conversion table, unpacking the master data into it, and then copy the data to the real table on the slave. .bzrignore: New files added client/Makefile.am: New files added client/mysqlbinlog.cc: Functions in rpl_utility.cc is now needed by mysqlbinlog.cc. libmysqld/Makefile.am: New files added mysql-test/extra/rpl_tests/check_type.inc: Test include file to check a single type conversion. mysql-test/extra/rpl_tests/rpl_extraSlave_Col.test: Switching to use INT instead of TEXT for column that should not have matching types. mysql-test/extra/rpl_tests/rpl_row_basic.test: Adding code to enable type conversions for BIT tests since InnoDB cannot handle them properly due to incorrect information stored as metadata. mysql-test/extra/rpl_tests/type_conversions.test: Test file to check a set of type conversions with current settings of slave_type_conversions. mysql-test/suite/rpl/t/rpl_typeconv.test: Test file to test conversions from master to slave with all possible values for slave_type_conversions. The test also checks that the slave_type_conversions variable works as expected. sql/field.cc: Changing definition of compatible_field_size to both check if two field with identical base types are compatible and give an order between them if they are compatible. This only implement checking on the slave, so it will not affect replication from an old master to a new slave. sql/field.h: Changing prototypes for functions: - compatible_field_size() - init_for_tmp_table() - row_pack_length() sql/log_event.cc: Changing compability checks to build a conversion table if the fields are compatible, but does not have the same base type. sql/log_event_old.cc: Changing compability checks to build a conversion table if the fields are compatible, but does not have the same base type. sql/mysql_priv.h: Adding global option variable for SLAVE_TYPE_CONVERSIONS sql/mysqld.cc: Adding SLAVE_TYPE_CONVERSIONS global server variable. sql/rpl_record.cc: Changing unpack_row to use the conversion table if present. sql/rpl_rli.h: Removing function get_tabledef and replacing it with get_table_data(). This function retrieve data for table opened for replication, not just table definition. sql/rpl_utility.cc: Function table_def::compatible_with is changed to compare table on master and slave for compatibility and generate a conversions table if they are compatible. Computing real type of fields from metadata for ENUM and SET types. Computing pack_length correctly for ENUM, SET, and BLOB types. Adding optimization to not check compatibility if no slave type conversions are enabled. sql/rpl_utility.h: Changing prototypes since implementation has changed. Modifying table_def::type() to return real type instead of stored type. sql/set_var.cc: Adding SLAVE_TYPE_CONVERSIONS variable. sql/set_var.h: Adding SLAVE_TYPE_CONVERSIONS variable. sql/share/errmsg.txt: Adding error messages for slave type conversions. sql/sql_class.h: Adding SLAVE_TYPE_CONVERSIONS variable. sql/sql_select.cc: Correcting create_virtual_tmp_table() to compute null bit positions correctly in the presence of bit fields.
