BUG#21842 (Cluster fails to replicate to innodb or myisam with err 134 using TPC-B): Problem: A RBR event can contain incomplete row data (only key value and fields which have been changed). In that case, when the row is unpacked into record and written to a table, the missing fields get incorrect NULL values leading to master-slave inconsistency. Solution: Use values found in slave's table for columns which are not given in the rows event. The code for writing a single row uses the following algorithm: 1. unpack row_data into table->record[0], 2. try to insert record, 3. if duplicate record found, fetch it into table->record[0], 4. unpack row_data into table->record[0], 5. write table->record[0] into the table. Where row_data is the row as stored in the data area of a rows event. Thus: a) unpacking of row_data happens at the time when row is written into a table, b) when unpacking (in step 4), only columns present in row_data are overwritten - all other columns remain as they were found in the table. Since all data needed for the above algorithm is stored inside Rows_log_event class, functions which locate and write rows are turned into methods of that class. replace_record() -> Rows_log_event::write_row() find_and_fetch_row() -> Rows_log_event::find_row() Both methods take row data from event's data buffer - the row being processed is pointed by m_curr_row. They unpack the data as needed into table's record buffers record[0] or record[1]. When row is unpacked, m_curr_row_end is set to point at next row in the data buffer. Other changes introduced in this changeset: - Change signature of unpack_row(): don't report errors and don't setup table's rw_set here. Errors can happen only when setting default values in prepare_record() function and are detected there. - In Rows_log_event and derived classes, don't pass arguments to the execution primitives (do_...() member functions) but use class members instead. - Move old row handling code into log_event_old.cc to be used by *_rows_log_event_old classes. Also, a new test rpl_ndb_2other is added which tests basic replication from master using ndb tables to slave storing the same tables using (possibly) different engine (myisam,innodb). Test is based on existing tests rpl_ndb_2myisam and rpl_ndb_2innodb. However, these tests doesn't work for various reasons and currently are disabled (see BUG#19227). The new test differs from the ones it is based on as follows: 1. Single test tests replication with different storage engines on slave (myisam, innodb, ndb). 2. Include file extra/rpl_tests/rpl_ndb_2multi_eng.test containing original tests is replaced by extra/rpl_tests/rpl_ndb_2multi_basic.test which doesn't contain tests using partitioned tables as these don't work currently. Instead, it tests replication to a slave which has more or less columns than master. 3. Include file include/rpl_multi_engine3.inc is replaced with include/rpl_multi_engine2.inc. The later differs by performing slightly different operations (updating more than one row in the table) and clearing table with "TRUNCATE TABLE" statement instead of "DELETE FROM" as replication of "DELETE" doesn't work well in this setting. 4. Slave must use option --log-slave-updates=0 as otherwise execution of replication events generated by ndb fails if table uses a different storage engine on slave (see BUG#29569). sql/log_event.cc: - Initialization of new Rows_log_event members. - Fixing some typos in documentation. In Rows_log_event::do_apply_event: - Set COMPLETE_ROWS_F flag (when master and slave have the same number of columns and all colums are present in the row) - Move initialization of tables write/read sets here, outside the rows processing loop (and out of unpack_row() function). - Remove calls to do_prepare_row() - no longer needed. - Add code managing m_curr_row and m_curr_row_end pointers. - Change signatures of row processing methods of Rows_log_event and it descendants - now most arguments are taken from class members. - Remove do_prepare_row() methods which are no longer used. - The auto_afree_ptr template is moved to rpl_utility.h (so that it can be used in log_event_old.cc). - Removed copy_extra_fields() function - no longer used. In Rows_log_event::write_row (former replace_record): - The old code is moved to log_event_old.cc. - Use prepare_record() and non-destructive unpack_current_row() to fill record with data. - In case a record being inserted already exists on slave and row data is incomplete use the record found and non-destructive unpack_current_row() to combine new column values with existing ones. - More debug info added. In Rows_log_event::find_row (former find_and_fetch_row function): - The old code is moved to log_event_old.cc. - Unpacking of the row is moved here. - In case of search using PK, the key data is prepared here. - More debug info added. - Remove initialization of Rows_log_event::m_after_image buffer which is no longer used. - Use new row unpacking methods in Update_rows_log_event::do_exec_row() to create before and after image. Note: all existing code used by Rows_log_event::do_apply_event() has been moved to log_event_old.cc to be used by *_rows_log_event_old classes. sql/log_event.h: - Add new COMPLETE_ROWS_F flag in Rows_log_event. - Add Rows_log_event members describing the row being processed. - Add a pointer to key buffer which is used in derived classes. - Add new methods: find__row(), write_row() and unpack_current_row(). - Change signatures of do_...() methods (replace method arguments by class members). - Remove do_prepare_row() method which is no longer used. - Update method documentation. - Add Old_rows_log_event class, which contains the old row processing code, as a friend of Rows_log_event so that it can access all members of an event instance. sql/log_event_old.cc: Move here old implementation of Rows_log_event::do_apply_event() and helper methods. sql/log_event_old.h: - Define new class Old_rows_log_event encapsulating old version of Rows_log_event::do_apply_event() and the helper methods. - Add the Old_rows_log_event class as a base for *_old versions of RBR event classes, ensure that the old version of do_apply_event() is called. - For *_old classes, declare the helper methods used in the old version of do_apply_event(). sql/rpl_record.cc: - Make unpack_row non-destructive for columns not present in the row. - Don't fill read/write set here as it is done outside these functions. - Move initialization of a record with default values to a separate function prepare_record(). sql/rpl_record.h: - Change signature of unpack_row(). - Declare function prepare_record(). sql/rpl_utility.cc: Make tabe_def::calc_field_size() a const method. sql/rpl_utility.h: Make table_def::calc_field_size() a const method. Move auto_afree_ptr template here so that it can be re-used (currently in log_event.cc and log_event_old.cc). Similar with DBUG_PRINT_BITSET macro. mysql-test/extra/rpl_tests/rpl_ndb_2multi_basic.test: Modification of rpl_ndb_2multi_eng test. Tests with partitioned tables are removed and a setup with slave having different number of columns than master is added. mysql-test/include/rpl_multi_engine2.inc: Modification of rpl_multi_engine3.inc which operates on more rows and replaces "DELETE FROM t1" with "TRUNCATE TABLE t1" as the first form doesn't replicate in NDB -> non-NDB setting (BUG#28538). mysql-test/suite/rpl_ndb/r/rpl_ndb_2other.result: Results of the test. mysql-test/suite/rpl_ndb/t/rpl_ndb_2other-slave.opt: Test options. --log-slave-updates=0 is compulsory as otherwise non-NDB slave applying row events from NDB master will fail when trying to log them. mysql-test/suite/rpl_ndb/t/rpl_ndb_2other.test: Test replication of NDB table to slave using other engine. The main test is in extra/rpl_tests/rpl_ndb_2multi_basic.test. It is included here several times with different settings of default storage engine on slave.

BUG#31581: 5.1-telco-6.1 -> 5.1.22. Slave crashes during starting This patch has two purposes: (1) To refactor the code so that {Write|Update|Delete}_rows_log_event_old does not use code from {Write|Update|Delete}_rows_log_event. Before refactoring there was the following problem: whenever we modifed the code for new events, it affected the old events. This is bad, as it makes maintainance difficult. After refactoring, we can safely edit the new code without affecting old events. So, if we for instance modify the binary format of new events, we no longer need to worry about how the new code reads old events. (2) To fix BUG#31581. These two objectives are reached by the following changes: - Merged Rows_log_event into Old_rows_log_event and {Write|Update|Delete}_rows_log_event into {Write|Update|Delete}_rows_log_event_old. - Fixed the bug by replacing {WRITE|UPDATE|DELETE}_ROWS_EVENT by PRE_GA_{WRITE|UPDATE|DELETE}_ROWS_EVENT. - Added comments to log_event_old.h (This patch is identical to the previously committed patch which was a collapse of three changesets, except that it adds assert(0) to constructors for old types of row log events that should never be called.) sql/log_event_old.cc: Merged Rows_log_event into Old_rows_log_event and {Write|Update|Delete}_rows_log_event into {Write|Update|Delete}_rows_log_event_old.

Errors can happen only when setting default values in prepare_record() function and are detected there. - In Rows_log_event and derived classes, don't pass arguments to the execution primitives (do_...() member functions) but use class members instead. - Move old row handling code into log_event_old.cc to be used by *_rows_log_event_old classes. Also, a new test rpl_ndb_2other is added which tests basic replication from master using ndb tables to slave storing the same tables using (possibly) different engine (myisam,innodb). Test is based on existing tests rpl_ndb_2myisam and rpl_ndb_2innodb. However, these tests doesn't work for various reasons and currently are disabled (see BUG#19227). The new test differs from the ones it is based on as follows: 1. Single test tests replication with different storage engines on slave (myisam, innodb, ndb). 2. Include file extra/rpl_tests/rpl_ndb_2multi_eng.test containing original tests is replaced by extra/rpl_tests/rpl_ndb_2multi_basic.test which doesn't contain tests using partitioned tables as these don't work currently. Instead, it tests replication to a slave which has more or less columns than master. 3. Include file include/rpl_multi_engine3.inc is replaced with include/rpl_multi_engine2.inc. The later differs by performing slightly different operations (updating more than one row in the table) and clearing table with "TRUNCATE TABLE" statement instead of "DELETE FROM" as replication of "DELETE" doesn't work well in this setting. 4. Slave must use option --log-slave-updates=0 as otherwise execution of replication events generated by ndb fails if table uses a different storage engine on slave (see BUG#29569). sql/log_event.cc: - Initialization of new Rows_log_event members. - Fixing some typos in documentation. In Rows_log_event::do_apply_event: - Set COMPLETE_ROWS_F flag (when master and slave have the same number of columns and all colums are present in the row) - Move initialization of tables write/read sets here, outside the rows processing loop (and out of unpack_row() function). - Remove calls to do_prepare_row() - no longer needed. - Add code managing m_curr_row and m_curr_row_end pointers. - Change signatures of row processing methods of Rows_log_event and it descendants - now most arguments are taken from class members. - Remove do_prepare_row() methods which are no longer used. - The auto_afree_ptr template is moved to rpl_utility.h (so that it can be used in log_event_old.cc). - Removed copy_extra_fields() function - no longer used. In Rows_log_event::write_row (former replace_record): - The old code is moved to log_event_old.cc. - Use prepare_record() and non-destructive unpack_current_row() to fill record with data. - In case a record being inserted already exists on slave and row data is incomplete use the record found and non-destructive unpack_current_row() to combine new column values with existing ones. - More debug info added.

BUG#31581: 5.1-telco-6.1 -> 5.1.22. Slave crashes during starting This patch has two purposes: (1) To refactor the code so that {Write|Update|Delete}_rows_log_event_old does not use code from {Write|Update|Delete}_rows_log_event. Before refactoring there was the following problem: whenever we modifed the code for new events, it affected the old events. This is bad, as it makes maintainance difficult. After refactoring, we can safely edit the new code without affecting old events. So, if we for instance modify the binary format of new events, we no longer need to worry about how the new code reads old events. (2) To fix BUG#31581. These two objectives are reached by the following changes: - Merged Rows_log_event into Old_rows_log_event and {Write|Update|Delete}_rows_log_event into {Write|Update|Delete}_rows_log_event_old. - Fixed the bug by replacing {WRITE|UPDATE|DELETE}_ROWS_EVENT by PRE_GA_{WRITE|UPDATE|DELETE}_ROWS_EVENT. - Added comments to log_event_old.h (This patch is identical to the previously committed patch which was a collapse of three changesets, except that it adds assert(0) to constructors for old types of row log events that should never be called.) sql/log_event_old.cc: Merged Rows_log_event into Old_rows_log_event and {Write|Update|Delete}_rows_log_event into {Write|Update|Delete}_rows_log_event_old. Also fixed the bug by replacing {WRITE|UPDATE|DELETE}_ROWS_EVENT by PRE_GA_{WRITE|UPDATE|DELETE}_ROWS_EVENT. sql/log_event_old.h: Merged Rows_log_event into Old_rows_log_event and {Write|Update|Delete}_rows_log_event into {Write|Update|Delete}_rows_log_event_old. Also added comment explaining what the file contains and what the classes do.

BUG#21842 (Cluster fails to replicate to innodb or myisam with err 134 using TPC-B): Problem: A RBR event can contain incomplete row data (only key value and fields which have been changed). In that case, when the row is unpacked into record and written to a table, the missing fields get incorrect NULL values leading to master-slave inconsistency. Solution: Use values found in slave's table for columns which are not given in the rows event. The code for writing a single row uses the following algorithm: 1. unpack row_data into table->record[0], 2. try to insert record, 3. if duplicate record found, fetch it into table->record[0], 4. unpack row_data into table->record[0], 5. write table->record[0] into the table. Where row_data is the row as stored in the data area of a rows event. Thus: a) unpacking of row_data happens at the time when row is written into a table, b) when unpacking (in step 4), only columns present in row_data are overwritten - all other columns remain as they were found in the table. Since all data needed for the above algorithm is stored inside Rows_log_event class, functions which locate and write rows are turned into methods of that class. replace_record() -> Rows_log_event::write_row() find_and_fetch_row() -> Rows_log_event::find_row() Both methods take row data from event's data buffer - the row being processed is pointed by m_curr_row. They unpack the data as needed into table's record buffers record[0] or record[1]. When row is unpacked, m_curr_row_end is set to point at next row in the data buffer. Other changes introduced in this changeset: - Change signature of unpack_row(): don't report errors and don't setup table's rw_set here.

Solution: Use values found in slave's table for columns which are not given in the rows event. The code for writing a single row uses the following algorithm: 1. unpack row_data into table->record[0], 2. try to insert record, 3. if duplicate record found, fetch it into table->record[0], 4. unpack row_data into table->record[0], 5. write table->record[0] into the table. Where row_data is the row as stored in the data area of a rows event. Thus: a) unpacking of row_data happens at the time when row is written into a table, b) when unpacking (in step 4), only columns present in row_data are overwritten - all other columns remain as they were found in the table. Since all data needed for the above algorithm is stored inside Rows_log_event class, functions which locate and write rows are turned into methods of that class. replace_record() -> Rows_log_event::write_row() find_and_fetch_row() -> Rows_log_event::find_row() Both methods take row data from event's data buffer - the row being processed is pointed by m_curr_row. They unpack the data as needed into table's record buffers record[0] or record[1]. When row is unpacked, m_curr_row_end is set to point at next row in the data buffer. Other changes introduced in this changeset: - Change signature of unpack_row(): don't report errors and don't setup table's rw_set here. Errors can happen only when setting default values in prepare_record() function and are detected there. - In Rows_log_event and derived classes, don't pass arguments to the execution primitives (do_...() member functions) but use class members instead. - Move old row handling code into log_event_old.cc to be used by *_rows_log_event_old classes. Also, a new test rpl_ndb_2other is added which tests basic replication from master using ndb tables to slave storing the same tables using (possibly) different engine (myisam,innodb). Test is based on existing tests rpl_ndb_2myisam and rpl_ndb_2innodb. However, these tests doesn't work for various reasons and currently are disabled (see BUG#19227). The new test differs from the ones it is based on as follows: 1. Single test tests replication with different storage engines on slave (myisam, innodb, ndb). 2. Include file extra/rpl_tests/rpl_ndb_2multi_eng.test containing original tests is replaced by extra/rpl_tests/rpl_ndb_2multi_basic.test which doesn't contain tests using partitioned tables as these don't work currently. Instead, it tests replication to a slave which has more or less columns than master. 3. Include file include/rpl_multi_engine3.inc is replaced with include/rpl_multi_engine2.inc. The later differs by performing slightly different operations (updating more than one row in the table) and clearing table with "TRUNCATE TABLE" statement instead of "DELETE FROM" as replication of "DELETE" doesn't work well in this setting. 4. Slave must use option --log-slave-updates=0 as otherwise execution of replication events generated by ndb fails if table uses a different storage engine on slave (see BUG#29569). sql/log_event.cc: - Initialization of new Rows_log_event members. - Fixing some typos in documentation. In Rows_log_event::do_apply_event: - Set COMPLETE_ROWS_F flag (when master and slave have the same number of columns and all colums are present in the row) - Move initialization of tables write/read sets here, outside the rows processing loop (and out of unpack_row() function). - Remove calls to do_prepare_row() - no longer needed. - Add code managing m_curr_row and m_curr_row_end pointers. - Change signatures of row processing methods of Rows_log_event and it descendants - now most arguments are taken from class members. - Remove do_prepare_row() methods which are no longer used. - The auto_afree_ptr template is moved to rpl_utility.h (so that it can be used in log_event_old.cc). - Removed copy_extra_fields() function - no longer used. In Rows_log_event::write_row (former replace_record): - The old code is moved to log_event_old.cc. - Use prepare_record() and non-destructive unpack_current_row() to fill record with data. - In case a record being inserted already exists on slave and row data is incomplete use the record found and non-destructive unpack_current_row() to combine new column values with existing ones. - More debug info added. In Rows_log_event::find_row (former find_and_fetch_row function): - The old code is moved to log_event_old.cc. - Unpacking of the row is moved here. - In case of search using PK, the key data is prepared here. - More debug info added. - Remove initialization of Rows_log_event::m_after_image buffer which is no longer used. - Use new row unpacking methods in Update_rows_log_event::do_exec_row() to create before and after image. Note: all existing code used by Rows_log_event::do_apply_event() has been moved to log_event_old.cc to be used by *_rows_log_event_old classes. sql/log_event.h: - Add new COMPLETE_ROWS_F flag in Rows_log_event. - Add Rows_log_event members describing the row being processed. - Add a pointer to key buffer which is used in derived classes. - Add new methods: find__row(), write_row() and unpack_current_row(). - Change signatures of do_...() methods (replace method arguments by class members). - Remove do_prepare_row() method which is no longer used. - Update method documentation. - Add Old_rows_log_event class, which contains the old row processing code, as a friend of Rows_log_event so that it can access all members of an event instance. sql/log_event_old.cc: Move here old implementation of Rows_log_event::do_apply_event() and helper methods. sql/log_event_old.h: - Define new class Old_rows_log_event encapsulating old version of Rows_log_event::do_apply_event() and the helper methods. - Add the Old_rows_log_event class as a base for *_old versions of RBR event classes, ensure that the old version of do_apply_event() is called. - For *_old classes, declare the helper methods used in the old version of do_apply_event(). sql/rpl_record.cc: - Make unpack_row non-destructive for columns not present in the row. - Don't fill read/write set here as it is done outside these functions. - Move initialization of a record with default values to a separate function prepare_record(). sql/rpl_record.h: - Change signature of unpack_row(). - Declare function prepare_record(). sql/rpl_utility.cc: Make tabe_def::calc_field_size() a const method. sql/rpl_utility.h: Make table_def::calc_field_size() a const method. Move auto_afree_ptr template here so that it can be re-used (currently in log_event.cc and log_event_old.cc). Similar with DBUG_PRINT_BITSET macro. mysql-test/extra/rpl_tests/rpl_ndb_2multi_basic.test: Modification of rpl_ndb_2multi_eng test. Tests with partitioned tables are removed and a setup with slave having different number of columns than master is added. mysql-test/include/rpl_multi_engine2.inc: Modification of rpl_multi_engine3.inc which operates on more rows and replaces "DELETE FROM t1" with "TRUNCATE TABLE t1" as the first form doesn't replicate in NDB -> non-NDB setting (BUG#28538). mysql-test/suite/rpl_ndb/r/rpl_ndb_2other.result: Results of the test. mysql-test/suite/rpl_ndb/t/rpl_ndb_2other-slave.opt: Test options. --log-slave-updates=0 is compulsory as otherwise non-NDB slave applying row events from NDB master will fail when trying to log them. mysql-test/suite/rpl_ndb/t/rpl_ndb_2other.test: Test replication of NDB table to slave using other engine. The main test is in extra/rpl_tests/rpl_ndb_2multi_basic.test. It is included here several times with different settings of default storage engine on slave.

BUG#36197: flush tables (or little table cache) can cause crash on slave When flushing tables, there were a slight chance that the flush was occuring between processing of two table map events. Since the tables are opened one by one, it might result in that the tables were not valid and that sub- sequent locking of tables would cause the slave to crash. The problem is solved by opening and locking all tables at once using simple_open_n_lock_tables(). Also, the patch contain a change to open_tables() so that pre-locking only takes place when the trg_event_map is not zero, which was not the case before (this caused the lock to be placed in thd->locked_tables instead of thd->lock since the assumption was that triggers would be called later and therefore the tables should be pre-locked). mysql-test/suite/rpl/r/rpl_found_rows.result: Result change mysql-test/suite/rpl/r/rpl_row_inexist_tbl.result: Result change mysql-test/suite/rpl/t/rpl_found_rows.test: Adding drop of table that was created in test. mysql-test/suite/rpl/t/rpl_slave_status.test: Adding waits for slave start and stop to ensure that test works. sql/log_event.cc: Replacing table-by-table open and lock with a single call to simple_open_n_lock_tables(), which in turn required some changes to other code. sql/log_event_old.cc: Replacing table-by-table open and lock with a single call to simple_open_n_lock_tables(), which in turn required some changes to other code. sql/sql_base.cc: Extending check inside open_tables() so that pre-locking in only done if tables->trg_egent_map is non-zero. mysql-test/include/wait_for_slave_sql_to_start.inc: New BitKeeper file ``mysql-test/include/wait_for_slave_sql_to_start.inc''

/*
BUG#39934: Slave stops for engine that only support row-based logging General overview: The logic for switching to row format when binlog_format=MIXED had numerous flaws. The underlying problem was the lack of a consistent architecture. General purpose of this changeset: This changeset introduces an architecture for switching to row format when binlog_format=MIXED. It enforces the architecture where it has to. It leaves some bugs to be fixed later. It adds extensive tests to verify that unsafe statements work as expected and that appropriate errors are produced by problems with the selection of binlog format. It was not practical to split this into smaller pieces of work. Problem 1: To determine the logging mode, the code has to take several parameters into account (namely: (1) the value of binlog_format; (2) the capabilities of the engines; (3) the type of the current statement: normal, unsafe, or row injection). These parameters may conflict in several ways, namely: - binlog_format=STATEMENT for a row injection - binlog_format=STATEMENT for an unsafe statement - binlog_format=STATEMENT for an engine only supporting row logging - binlog_format=ROW for an engine only supporting statement logging - statement is unsafe and engine does not support row logging - row injection in a table that does not support statement logging - statement modifies one table that does not support row logging and one that does not support statement logging Several of these conflicts were not detected, or were detected with an inappropriate error message. The problem of BUG#39934 was that no appropriate error message was written for the case when an engine only supporting row logging executed a row injection with binlog_format=ROW. However, all above cases must be handled. Fix 1: Introduce new error codes (sql/share/errmsg.txt). Ensure that all conditions are detected and handled in decide_logging_format() Problem 2: The binlog format shall be determined once per statement, in decide_logging_format(). It shall not be changed before or after that. Before decide_logging_format() is called, all information necessary to determine the logging format must be available. This principle ensures that all unsafe statements are handled in a consistent way. However, this principle is not followed: thd->set_current_stmt_binlog_row_based_if_mixed() is called in several places, including from code executing UPDATE..LIMIT, INSERT..SELECT..LIMIT, DELETE..LIMIT, INSERT DELAYED, and SET @@binlog_format. After Problem 1 was fixed, that caused inconsistencies where these unsafe statements would not print the appropriate warnings or errors for some of the conflicts. Fix 2: Remove calls to THD::set_current_stmt_binlog_row_based_if_mixed() from code executed after decide_logging_format(). Compensate by calling the set_current_stmt_unsafe() at parse time. This way, all unsafe statements are detected by decide_logging_format(). Problem 3: INSERT DELAYED is not unsafe: it is logged in statement format even if binlog_format=MIXED, and no warning is printed even if binlog_format=STATEMENT. This is BUG#45825. Fix 3: Made INSERT DELAYED set itself to unsafe at parse time. This allows decide_logging_format() to detect that a warning should be printed or the binlog_format changed. Problem 4: LIMIT clause were not marked as unsafe when executed inside stored functions/triggers/views/prepared statements. This is BUG#45785. Fix 4: Make statements containing the LIMIT clause marked as unsafe at parse time, instead of at execution time. This allows propagating unsafe-ness to the view. mysql-test/extra/rpl_tests/create_recursive_construct.inc: Added auxiliary file used by binlog_unsafe.test to create and execute recursive constructs (functions/procedures/triggers/views/prepared statements). mysql-test/extra/rpl_tests/rpl_foreign_key.test: removed unnecessary set @@session.binlog_format mysql-test/extra/rpl_tests/rpl_insert_delayed.test: Filter out table id from table map events in binlog listing. Got rid of $binlog_format_statement. mysql-test/extra/rpl_tests/rpl_ndb_apply_status.test: disable warnings around call to unsafe procedure mysql-test/include/rpl_udf.inc: Disabled warnings for code that generates warnings for some binlog formats. That would otherwise cause inconsistencies in the result file. mysql-test/r/mysqldump.result: Views are now unsafe if they contain a LIMIT clause. That fixed BUG#45831. Due to BUG#45832, a warning is printed for the CREATE VIEW statement. mysql-test/r/sp_trans.result: Unsafe statements in stored procedures did not give a warning if binlog_format=statement. This is BUG#45824. Now they do, so this result file gets a new warning. mysql-test/suite/binlog/r/binlog_multi_engine.result: Error message changed. mysql-test/suite/binlog/r/binlog_statement_insert_delayed.result: INSERT DELAYED didn't generate a warning when binlog_format=STATEMENT. That was BUG#45825. Now there is a warning, so result file needs to be updated. mysql-test/suite/binlog/r/binlog_stm_ps.result: Changed error message. mysql-test/suite/binlog/r/binlog_unsafe.result: updated result file: - error message changed - added test for most combinations of unsafe constructs invoked from recursive constructs - INSERT DELAYED now gives a warning (because BUG#45826 is fixed) - INSERT..SELECT..LIMIT now gives a warning from inside recursive constructs (because BUG#45785 was fixed) - When a recursive construct (e.g., stored proc or function) contains more than one statement, at least one of which is unsafe, then all statements in the recursive construct give warnings. This is a new bug introduced by this changeset. It will be addressed in a post-push fix. mysql-test/suite/binlog/t/binlog_innodb.test: Changed error code for innodb updates with READ COMMITTED or READ UNCOMMITTED transaction isolation level and binlog_format=statement. mysql-test/suite/binlog/t/binlog_multi_engine.test: The error code has changed for statements where more than one engine is involved and one of them is self-logging. mysql-test/suite/binlog/t/binlog_unsafe-master.opt: Since binlog_unsafe now tests unsafe-ness of UDF's, we need an extra flag in the .opt file. mysql-test/suite/binlog/t/binlog_unsafe.test: - Clarified comment. - Rewrote first part of test. Now it tests not only unsafe variables and functions, but also unsafe-ness due to INSERT..SELECT..LIMIT, INSERT DELAYED, insert into two autoinc columns, use of UDF's, and access to log tables in the mysql database. Also, in addition to functions, procedures, triggers, and prepared statements, it now also tests views; and it constructs recursive calls in two levels by combining these recursive constructs. Part of the logic is in extra/rpl_tests/create_recursive_construct.inc. - added tests for all special system variables that should not be unsafe. - added specific tests for BUG#45785 and BUG#45825 mysql-test/suite/rpl/r/rpl_events.result: updated result file mysql-test/suite/rpl/r/rpl_extraColmaster_innodb.result: updated result file mysql-test/suite/rpl/r/rpl_extraColmaster_myisam.result: updated result file mysql-test/suite/rpl/r/rpl_foreign_key_innodb.result: updated result file mysql-test/suite/rpl/r/rpl_idempotency.result: updated result file mysql-test/suite/rpl/r/rpl_mix_found_rows.result: Split rpl_found_rows.test into rpl_mix_found_rows.test (a new file) and rpl_stm_found_rows.test (renamed rpl_found_rows.test). This file equals the second half of the old rpl_found_rows.result, with the following modifications: - minor formatting changes - additional initialization mysql-test/suite/rpl/r/rpl_mix_insert_delayed.result: Moved out code operating in mixed mode from rpl_stm_insert_delayed (into rpl_mix_insert_delayed) and got rid of explicit setting of binlog format. mysql-test/suite/rpl/r/rpl_rbr_to_sbr.result: updated result file mysql-test/suite/rpl/r/rpl_row_idempotency.result: Moved the second half of rpl_idempotency.test, which only executed in row mode, to rpl_row_idempotency.test. This is the new result file. mysql-test/suite/rpl/r/rpl_row_insert_delayed.result: Got rid of unnecessary explicit setting of binlog format. mysql-test/suite/rpl/r/rpl_stm_found_rows.result: Split rpl_found_rows.test into rpl_mix_found_rows.test (a new file) and rpl_stm_found_rows.test (renamed rpl_found_rows.test). Changes in this file: - minor formatting changes - warning is now issued for unsafe statements inside procedures (since BUG#45824 is fixed) - second half of file is moved to rpl_mix_found_rows.result mysql-test/suite/rpl/r/rpl_stm_insert_delayed.result: Moved out code operating in mixed mode from rpl_stm_insert_delayed (into rpl_mix_insert_delayed) and got rid of explicit setting of binlog format. mysql-test/suite/rpl/r/rpl_stm_loadfile.result: error message changed mysql-test/suite/rpl/r/rpl_temporary_errors.result: updated result file mysql-test/suite/rpl/r/rpl_udf.result: Remove explicit set of binlog format (and triplicate test execution) and rely on test system executing the test in all binlog formats. mysql-test/suite/rpl/t/rpl_bug31076.test: Test is only valid in mixed or row mode since it generates row events. mysql-test/suite/rpl/t/rpl_events.test: Removed explicit set of binlog_format and removed duplicate testing. Instead, we rely on the test system to try all binlog formats. mysql-test/suite/rpl/t/rpl_extraColmaster_innodb.test: Removed triplicate testing and instead relying on test system. Test is only relevant for row format since statement-based replication cannot handle extra columns on master. mysql-test/suite/rpl/t/rpl_extraColmaster_myisam.test: Removed triplicate testing and instead relying on test system. Test is only relevant for row format since statement-based replication cannot handle extra columns on master. mysql-test/suite/rpl/t/rpl_idempotency-slave.opt: Removed .opt file to avoid server restarts. mysql-test/suite/rpl/t/rpl_idempotency.test: - Moved out row-only tests to a new test file, rpl_row_idempotency.test. rpl_idempotency now only contains tests that execute in all binlog_formats. - While I was here, also removed .opt file to avoid server restarts. The slave_exec_mode is now set inside the test instead. mysql-test/suite/rpl/t/rpl_mix_found_rows.test: Split rpl_found_rows.test into rpl_mix_found_rows.test (a new file) and rpl_stm_found_rows.test (renamed rpl_found_rows.test). This file contains the second half of the original rpl_found_rows.test with the follwing changes: - initialization - removed SET_BINLOG_FORMAT and added have_binlog_format_mixed.inc - minor formatting changes mysql-test/suite/rpl/t/rpl_mix_insert_delayed.test: Moved out code operating in mixed mode from rpl_stm_insert_delayed (into rpl_mix_insert_delayed) and got rid of explicit setting of binlog format. mysql-test/suite/rpl/t/rpl_rbr_to_sbr.test: Test cannot execute in statement mode, since we no longer switch to row format when binlog_format=statement. Enforced mixed mode throughout the test. mysql-test/suite/rpl/t/rpl_row_idempotency.test: Moved the second half of rpl_idempotency.test, which only executed in row mode, to this new file. We now rely on the test system to set binlog format. mysql-test/suite/rpl/t/rpl_row_insert_delayed.test: - Got rid of unnecessary explicit setting of binlog format. - extra/rpl_tests/rpl_insert_delayed.test does not need the $binlog_format_statement variable any more, so that was removed. mysql-test/suite/rpl/t/rpl_slave_skip.test: The test switches binlog_format internally and master generates both row and statement events. Hence, the slave must be able to log in both statement and row format. Hence test was changed to only execute in mixed mode. mysql-test/suite/rpl/t/rpl_stm_found_rows.test: Split rpl_found_rows.test into rpl_mix_found_rows.test (a new file) and rpl_stm_found_rows.test (renamed rpl_found_rows.test). Changes in this file: - minor formatting changes - added have_binlog_format_statement and removed SET BINLOG_FORMAT. - second half of file is moved to rpl_mix_found_rows.test - added cleanup code mysql-test/suite/rpl/t/rpl_stm_insert_delayed.test: Moved out code operating in mixed mode from rpl_stm_insert_delayed (into rpl_mix_insert_delayed) and got rid of explicit setting of binlog format. mysql-test/suite/rpl/t/rpl_switch_stm_row_mixed.test: The test switches binlog_format internally and master generates both row and statement events. Hence, the slave must be able to log in both statement and row format. Hence test was changed to only execute in mixed mode on slave. mysql-test/suite/rpl/t/rpl_temporary_errors.test: Removed explicit set of binlog format. Instead, the test now only executes in row mode. mysql-test/suite/rpl/t/rpl_udf.test: Remove explicit set of binlog format (and triplicate test execution) and rely on test system executing the test in all binlog formats. mysql-test/suite/rpl_ndb/combinations: Added combinations file for rpl_ndb. mysql-test/suite/rpl_ndb/r/rpl_ndb_binlog_format_errors.result: new result file mysql-test/suite/rpl_ndb/r/rpl_ndb_circular_simplex.result: updated result file mysql-test/suite/rpl_ndb/t/rpl_ndb_2innodb.test: The test needs slave to be able to switch to row mode, so the test was changed to only execute in mixed and row mode. mysql-test/suite/rpl_ndb/t/rpl_ndb_2myisam.test: The test needs slave to be able to switch to row mode, so the test was changed to only execute in mixed and row mode. mysql-test/suite/rpl_ndb/t/rpl_ndb_basic.test: The test needs slave to be able to switch to row mode, so the test was changed to only execute in mixed and row mode. mysql-test/suite/rpl_ndb/t/rpl_ndb_binlog_format_errors-master.opt: new option file mysql-test/suite/rpl_ndb/t/rpl_ndb_binlog_format_errors-slave.opt: new option file mysql-test/suite/rpl_ndb/t/rpl_ndb_binlog_format_errors.test: New test case to verify all errors and warnings generated by decide_logging_format. mysql-test/suite/rpl_ndb/t/rpl_ndb_blob.test: The test needs slave to be able to switch to row mode, so the test was changed to only execute in mixed and row mode. mysql-test/suite/rpl_ndb/t/rpl_ndb_blob2.test: The test needs slave to be able to switch to row mode, so the test was changed to only execute in mixed and row mode. mysql-test/suite/rpl_ndb/t/rpl_ndb_circular.test: The test needs slave to be able to switch to row mode, so the test was changed to only execute in mixed and row mode. mysql-test/suite/rpl_ndb/t/rpl_ndb_circular_simplex.test: The test needs slave to be able to switch to row mode, so the test was changed to only execute in mixed and row mode. While I was here, also made the test clean up after itself. mysql-test/suite/rpl_ndb/t/rpl_ndb_commit_afterflush.test: The test needs slave to be able to switch to row mode, so the test was changed to only execute in mixed and row mode. mysql-test/suite/rpl_ndb/t/rpl_ndb_ctype_ucs2_def.test: The test needs slave to be able to switch to row mode, so the test was changed to only execute in mixed and row mode. mysql-test/suite/rpl_ndb/t/rpl_ndb_delete_nowhere.test: The test needs slave to be able to switch to row mode, so the test was changed to only execute in mixed and row mode. mysql-test/suite/rpl_ndb/t/rpl_ndb_do_db.test: The test needs slave to be able to switch to row mode, so the test was changed to only execute in mixed and row mode. mysql-test/suite/rpl_ndb/t/rpl_ndb_do_table.test: The test needs slave to be able to switch to row mode, so the test was changed to only execute in mixed and row mode. mysql-test/suite/rpl_ndb/t/rpl_ndb_func003.test: The test needs slave to be able to switch to row mode, so the test was changed to only execute in mixed and row mode. mysql-test/suite/rpl_ndb/t/rpl_ndb_innodb_trans.test: The test needs slave to be able to switch to row mode, so the test was changed to only execute in mixed and row mode. mysql-test/suite/rpl_ndb/t/rpl_ndb_insert_ignore.test: The test needs slave to be able to switch to row mode, so the test was changed to only execute in mixed and row mode. mysql-test/suite/rpl_ndb/t/rpl_ndb_mixed_engines_transactions.test: The test needs slave to be able to switch to row mode, so the test was changed to only execute in mixed and row mode. mysql-test/suite/rpl_ndb/t/rpl_ndb_multi_update3.test: The test needs slave to be able to switch to row mode, so the test was changed to only execute in mixed and row mode. mysql-test/suite/rpl_ndb/t/rpl_ndb_rep_ignore.test: The test needs slave to be able to switch to row mode, so the test was changed to only execute in mixed and row mode. mysql-test/suite/rpl_ndb/t/rpl_ndb_row_001.test: The test needs slave to be able to switch to row mode, so the test was changed to only execute in mixed and row mode. mysql-test/suite/rpl_ndb/t/rpl_ndb_sp003.test: The test needs slave to be able to switch to row mode, so the test was changed to only execute in mixed and row mode. mysql-test/suite/rpl_ndb/t/rpl_ndb_sp006.test: The test needs slave to be able to switch to row mode, so the test was changed to only execute in mixed and row mode. mysql-test/suite/rpl_ndb/t/rpl_ndb_trig004.test: The test needs slave to be able to switch to row mode, so the test was changed to only execute in mixed and row mode. mysql-test/t/partition_innodb_stmt.test: Changed error code for innodb updates with READ COMMITTED or READ UNCOMMITTED transaction isolation level and binlog_format=statement. sql/event_db_repository.cc: Use member function to read current_stmt_binlog_row_based. sql/events.cc: Use member function to read current_stmt_binlog_row_based. sql/ha_ndbcluster_binlog.cc: reset_current_stmt_binlog_row_based() is not a no-op for the ndb_binlog thread any more. Instead, the ndb_binlog thread now forces row mode both initially and just after calling mysql_parse. (mysql_parse() is the only place where reset_current_stmt_binlog_row_based() may be called from the ndb_binlog thread, so these are the only two places that need to change.) sql/ha_partition.cc: Use member function to read current_stmt_binlog_row_based. sql/handler.cc: Use member function to read current_stmt_binlog_row_based. sql/item_create.cc: Added DBUG_ENTER to some functions, to be able to trace when set_stmt_unsafe is called. sql/log.cc: Use member function to read current_stmt_binlog_row_based. sql/log_event.cc: - Moved logic for changing to row format out of do_apply_event (and into decide_logging_format). - Added @todo comment for post-push cleanup. sql/log_event_old.cc: Move logic for changing to row format out of do_apply_event (and into decide_logging_format). sql/mysql_priv.h: Make decide_logging_format() a member of the THD class, for two reasons: - It is natural from an object-oriented perspective. - decide_logging_format() needs to access private members of THD (specifically, the new binlog_warning_flags field). sql/rpl_injector.cc: Removed call to set_current_stmt_binlog_row_based(). From now on, only decide_logging_fromat is allowed to modify current_stmt_binlog_row_based. This call is from the ndb_binlog thread, mostly executing code in ha_ndbcluster_binlog.cc. This call can be safely removed, because: - current_stmt_binlog_row_based is initialized for the ndb_binlog thread's THD object when the THD object is created. So we're not going to read uninitialized memory. - The behavior of ndb_binlog thread does not use the state of the current_stmt_binlog_row_based. It is conceivable that the ndb_binlog thread would rely on the current_stmt_binlog_format in two situations: (1) when it calls mysql_parse; (2) when it calls THD::binlog_query. In case (1), it always clears THD::options&OPTION_BIN_LOG (because run_query() in ha_ndbcluster_binlog.cc is only called with disable_binlogging = TRUE). In case (2), it always uses qtype=STMT_QUERY_TYPE. sql/set_var.cc: Added @todo comment for post-push cleanup. sql/share/errmsg.txt: Added new error messages and clarified ER_BINLOG_UNSAFE_STATEMENT. sql/sp.cc: Added DBUG_ENTER, to be able to trace when set_stmt_unsafe is called. Got rid of MYSQL_QUERY_TYPE: it was equivalent to STMT_QUERY_TYPE. sql/sp_head.cc: Use member function to read current_stmt_binlog_row_based. sql/sp_head.h: Added DBUG_ENTER, to be able to trace when set_stmt_unsafe is called. sql/sql_acl.cc: Got rid of MYSQL_QUERY_TYPE: it was equivalent to STMT_QUERY_TYPE. sql/sql_base.cc: - Made decide_logging_format take care of all logic for deciding the logging format, and for determining the related warnings and errors. See comment above decide_logging_format for details. - Made decide_logging_format a member function of THD, since it needs to access private members of THD and since its purpose is to update the state of a THD object. - Added DBUG_ENTER, to be able to trace when set_stmt_unsafe is called. sql/sql_class.cc: - Moved logic for determining unsafe warnings away from THD::binlog_query (and into decide_logging_format()). Now, it works like this: 1. decide_logging_format detects that the current statement shall produce a warning, if it ever makes it to the binlog 2. decide_logging_format sets a flag of THD::binlog_warning_flags. 3. THD::binlog_query reads the flag. If the flag is set, it generates a warning. - Use member function to read current_stmt_binlog_row_based. sql/sql_class.h: - Added THD::binlog_warning_flags (see sql_class.cc for explanation). - Made decide_logging_format() and reset_for_next_command() member functions of THD (instead of standalone functions). This was needed for two reasons: (1) the functions need to access the private member THD::binlog_warning_flags; (2) the purpose of these functions is to update the staet of a THD object, so from an object-oriented point of view they should be member functions. - Encapsulated current_stmt_binlog_row_based, so it is now private and can only be accessed from a member function. Also changed the data type to an enumeration instead of a bool. - Removed MYSQL_QUERY_TYPE, because it was equivalent to STMT_QUERY_TYPE anyways. - When reset_current_stmt_binlog_row_based was called from the ndb_binlog thread, it would behave as a no-op. This special case has been removed, and the behavior of reset_current_stmt_binlog_row_based does not depend on which thread calls it any more. The special case did not serve any purpose, since the ndb binlog thread did not take the current_stmt_binlog_row_based flag into account anyways. sql/sql_delete.cc: - Moved logic for setting row format for DELETE..LIMIT away from mysql_prepare_delete. (Instead, we mark the statement as unsafe at parse time (sql_yacc.yy) and rely on decide_logging_format() (sql_class.cc) to set row format.) This is part of the fix for BUG#45831. - Use member function to read current_stmt_binlog_row_based. sql/sql_insert.cc: - Removed unnecessary calls to thd->lex->set_stmt_unsafe() and thd->set_current_stmt_binlog_row_based_if_mixed() from handle_delayed_insert(). The calls are unnecessary because they have already been made; they were made in the constructor of the `di' object. - Since decide_logging_format() is now a member function of THD, code that calls decide_logging_format() had to be updated. - Added DBUG_ENTER call, to be able to trace when set_stmt_unsafe is called. - Moved call to set_stmt_unsafe() for INSERT..SELECT..LIMIT away from mysql_insert_select_prepare() (and into decide_logging_format). This is part of the fix for BUG#45831. - Use member function to read current_stmt_binlog_row_based. sql/sql_lex.h: - Added the flag BINLOG_STMT_FLAG_ROW_INJECTION to enum_binlog_stmt_flag. This was necessary so that a statement can identify itself as a row injection. - Added appropriate setter and getter functions for the new flag. - Added or clarified some comments. - Added DBUG_ENTER() sql/sql_load.cc: Use member function to read current_stmt_binlog_row_based. sql/sql_parse.cc: - Made mysql_reset_thd_for_next_command() clear thd->binlog_warning_flags. - Since thd->binlog_warning_flags is private, it must be set in a member function of THD. Hence, moved the body of mysql_reset_thd_for_next_command() to the new member function THD::reset_thd_for_next_command(), and made mysql_reset_thd_for_next_command() call THD::reset_thd_for_next_command(). - Removed confusing comment. - Use member function to read current_stmt_binlog_row_based. sql/sql_repl.cc: Use member function to read current_stmt_binlog_row_based. sql/sql_table.cc: Use member function to read current_stmt_binlog_row_based. sql/sql_udf.cc: Use member function to read current_stmt_binlog_row_based. sql/sql_update.cc: Moved logic for setting row format for UPDATE..LIMIT away from mysql_prepare_update. (Instead, we mark the statement as unsafe at parse time (sql_yacc.yy) and rely on decide_logging_format() (sql_class.cc) to set row format.) This is part of the fix for BUG#45831. sql/sql_yacc.yy: Made INSERT DELAYED, INSERT..SELECT..LIMIT, UPDATE..LIMIT, and DELETE..LIMIT mark themselves as unsafe at parse time (instead of at execution time). This is part of the fixes BUG#45831 and BUG#45825. storage/example/ha_example.cc: Made exampledb accept inserts. This was needed by the new test case rpl_ndb_binlog_format_errors, because it needs an engine that is statement-only (and accepts inserts). storage/example/ha_example.h: Made exampledb a statement-only engine instead of a row-only engine. No existing test relied exampledb's row-only capabilities. The new test case rpl_ndb_binlog_format_errors needs an engine that is statement-only. storage/innobase/handler/ha_innodb.cc: - Changed error error code and message given by innodb when binlog_format=STATEMENT and transaction isolation level is READ COMMITTED or READ UNCOMMITTED. - While I was here, also simplified the condition for checking when to give the error.

This is a row injection, so we flag the "statement" as
such. Note that this code is called both when the slave does row
injections and when the BINLOG statement is used to do row
injections.
BUG#36197: flush tables (or little table cache) can cause crash on slave When flushing tables, there were a slight chance that the flush was occuring between processing of two table map events. Since the tables are opened one by one, it might result in that the tables were not valid and that sub- sequent locking of tables would cause the slave to crash. The problem is solved by opening and locking all tables at once using simple_open_n_lock_tables(). Also, the patch contain a change to open_tables() so that pre-locking only takes place when the trg_event_map is not zero, which was not the case before (this caused the lock to be placed in thd->locked_tables instead of thd->lock since the assumption was that triggers would be called later and therefore the tables should be pre-locked). mysql-test/suite/rpl/r/rpl_found_rows.result: Result change mysql-test/suite/rpl/r/rpl_row_inexist_tbl.result: Result change mysql-test/suite/rpl/t/rpl_found_rows.test: Adding drop of table that was created in test. mysql-test/suite/rpl/t/rpl_slave_status.test: Adding waits for slave start and stop to ensure that test works. sql/log_event.cc: Replacing table-by-table open and lock with a single call to simple_open_n_lock_tables(), which in turn required some changes to other code. sql/log_event_old.cc: Replacing table-by-table open and lock with a single call to simple_open_n_lock_tables(), which in turn required some changes to other code. sql/sql_base.cc: Extending check inside open_tables() so that pre-locking in only done if tables->trg_egent_map is non-zero. mysql-test/include/wait_for_slave_sql_to_start.inc: New BitKeeper file ``mysql-test/include/wait_for_slave_sql_to_start.inc''

BUG#39934: Slave stops for engine that only support row-based logging General overview: The logic for switching to row format when binlog_format=MIXED had numerous flaws. The underlying problem was the lack of a consistent architecture. General purpose of this changeset: This changeset introduces an architecture for switching to row format when binlog_format=MIXED. It enforces the architecture where it has to. It leaves some bugs to be fixed later. It adds extensive tests to verify that unsafe statements work as expected and that appropriate errors are produced by problems with the selection of binlog format. It was not practical to split this into smaller pieces of work. Problem 1: To determine the logging mode, the code has to take several parameters into account (namely: (1) the value of binlog_format; (2) the capabilities of the engines; (3) the type of the current statement: normal, unsafe, or row injection). These parameters may conflict in several ways, namely: - binlog_format=STATEMENT for a row injection - binlog_format=STATEMENT for an unsafe statement - binlog_format=STATEMENT for an engine only supporting row logging - binlog_format=ROW for an engine only supporting statement logging - statement is unsafe and engine does not support row logging - row injection in a table that does not support statement logging - statement modifies one table that does not support row logging and one that does not support statement logging Several of these conflicts were not detected, or were detected with an inappropriate error message. The problem of BUG#39934 was that no appropriate error message was written for the case when an engine only supporting row logging executed a row injection with binlog_format=ROW. However, all above cases must be handled. Fix 1: Introduce new error codes (sql/share/errmsg.txt). Ensure that all conditions are detected and handled in decide_logging_format() Problem 2: The binlog format shall be determined once per statement, in decide_logging_format(). It shall not be changed before or after that. Before decide_logging_format() is called, all information necessary to determine the logging format must be available. This principle ensures that all unsafe statements are handled in a consistent way. However, this principle is not followed: thd->set_current_stmt_binlog_row_based_if_mixed() is called in several places, including from code executing UPDATE..LIMIT, INSERT..SELECT..LIMIT, DELETE..LIMIT, INSERT DELAYED, and SET @@binlog_format. After Problem 1 was fixed, that caused inconsistencies where these unsafe statements would not print the appropriate warnings or errors for some of the conflicts. Fix 2: Remove calls to THD::set_current_stmt_binlog_row_based_if_mixed() from code executed after decide_logging_format(). Compensate by calling the set_current_stmt_unsafe() at parse time. This way, all unsafe statements are detected by decide_logging_format(). Problem 3: INSERT DELAYED is not unsafe: it is logged in statement format even if binlog_format=MIXED, and no warning is printed even if binlog_format=STATEMENT. This is BUG#45825. Fix 3: Made INSERT DELAYED set itself to unsafe at parse time. This allows decide_logging_format() to detect that a warning should be printed or the binlog_format changed. Problem 4: LIMIT clause were not marked as unsafe when executed inside stored functions/triggers/views/prepared statements. This is BUG#45785. Fix 4: Make statements containing the LIMIT clause marked as unsafe at parse time, instead of at execution time. This allows propagating unsafe-ness to the view. mysql-test/extra/rpl_tests/create_recursive_construct.inc: Added auxiliary file used by binlog_unsafe.test to create and execute recursive constructs (functions/procedures/triggers/views/prepared statements). mysql-test/extra/rpl_tests/rpl_foreign_key.test: removed unnecessary set @@session.binlog_format mysql-test/extra/rpl_tests/rpl_insert_delayed.test: Filter out table id from table map events in binlog listing. Got rid of $binlog_format_statement. mysql-test/extra/rpl_tests/rpl_ndb_apply_status.test: disable warnings around call to unsafe procedure mysql-test/include/rpl_udf.inc: Disabled warnings for code that generates warnings for some binlog formats. That would otherwise cause inconsistencies in the result file. mysql-test/r/mysqldump.result: Views are now unsafe if they contain a LIMIT clause. That fixed BUG#45831. Due to BUG#45832, a warning is printed for the CREATE VIEW statement. mysql-test/r/sp_trans.result: Unsafe statements in stored procedures did not give a warning if binlog_format=statement. This is BUG#45824. Now they do, so this result file gets a new warning. mysql-test/suite/binlog/r/binlog_multi_engine.result: Error message changed. mysql-test/suite/binlog/r/binlog_statement_insert_delayed.result: INSERT DELAYED didn't generate a warning when binlog_format=STATEMENT. That was BUG#45825. Now there is a warning, so result file needs to be updated. mysql-test/suite/binlog/r/binlog_stm_ps.result: Changed error message. mysql-test/suite/binlog/r/binlog_unsafe.result: updated result file: - error message changed - added test for most combinations of unsafe constructs invoked from recursive constructs - INSERT DELAYED now gives a warning (because BUG#45826 is fixed) - INSERT..SELECT..LIMIT now gives a warning from inside recursive constructs (because BUG#45785 was fixed) - When a recursive construct (e.g., stored proc or function) contains more than one statement, at least one of which is unsafe, then all statements in the recursive construct give warnings. This is a new bug introduced by this changeset. It will be addressed in a post-push fix. mysql-test/suite/binlog/t/binlog_innodb.test: Changed error code for innodb updates with READ COMMITTED or READ UNCOMMITTED transaction isolation level and binlog_format=statement. mysql-test/suite/binlog/t/binlog_multi_engine.test: The error code has changed for statements where more than one engine is involved and one of them is self-logging. mysql-test/suite/binlog/t/binlog_unsafe-master.opt: Since binlog_unsafe now tests unsafe-ness of UDF's, we need an extra flag in the .opt file. mysql-test/suite/binlog/t/binlog_unsafe.test: - Clarified comment. - Rewrote first part of test. Now it tests not only unsafe variables and functions, but also unsafe-ness due to INSERT..SELECT..LIMIT, INSERT DELAYED, insert into two autoinc columns, use of UDF's, and access to log tables in the mysql database. Also, in addition to functions, procedures, triggers, and prepared statements, it now also tests views; and it constructs recursive calls in two levels by combining these recursive constructs. Part of the logic is in extra/rpl_tests/create_recursive_construct.inc. - added tests for all special system variables that should not be unsafe. - added specific tests for BUG#45785 and BUG#45825 mysql-test/suite/rpl/r/rpl_events.result: updated result file mysql-test/suite/rpl/r/rpl_extraColmaster_innodb.result: updated result file mysql-test/suite/rpl/r/rpl_extraColmaster_myisam.result: updated result file mysql-test/suite/rpl/r/rpl_foreign_key_innodb.result: updated result file mysql-test/suite/rpl/r/rpl_idempotency.result: updated result file mysql-test/suite/rpl/r/rpl_mix_found_rows.result: Split rpl_found_rows.test into rpl_mix_found_rows.test (a new file) and rpl_stm_found_rows.test (renamed rpl_found_rows.test). This file equals the second half of the old rpl_found_rows.result, with the following modifications: - minor formatting changes - additional initialization mysql-test/suite/rpl/r/rpl_mix_insert_delayed.result: Moved out code operating in mixed mode from rpl_stm_insert_delayed (into rpl_mix_insert_delayed) and got rid of explicit setting of binlog format. mysql-test/suite/rpl/r/rpl_rbr_to_sbr.result: updated result file mysql-test/suite/rpl/r/rpl_row_idempotency.result: Moved the second half of rpl_idempotency.test, which only executed in row mode, to rpl_row_idempotency.test. This is the new result file. mysql-test/suite/rpl/r/rpl_row_insert_delayed.result: Got rid of unnecessary explicit setting of binlog format. mysql-test/suite/rpl/r/rpl_stm_found_rows.result: Split rpl_found_rows.test into rpl_mix_found_rows.test (a new file) and rpl_stm_found_rows.test (renamed rpl_found_rows.test). Changes in this file: - minor formatting changes - warning is now issued for unsafe statements inside procedures (since BUG#45824 is fixed) - second half of file is moved to rpl_mix_found_rows.result mysql-test/suite/rpl/r/rpl_stm_insert_delayed.result: Moved out code operating in mixed mode from rpl_stm_insert_delayed (into rpl_mix_insert_delayed) and got rid of explicit setting of binlog format. mysql-test/suite/rpl/r/rpl_stm_loadfile.result: error message changed mysql-test/suite/rpl/r/rpl_temporary_errors.result: updated result file mysql-test/suite/rpl/r/rpl_udf.result: Remove explicit set of binlog format (and triplicate test execution) and rely on test system executing the test in all binlog formats. mysql-test/suite/rpl/t/rpl_bug31076.test: Test is only valid in mixed or row mode since it generates row events. mysql-test/suite/rpl/t/rpl_events.test: Removed explicit set of binlog_format and removed duplicate testing. Instead, we rely on the test system to try all binlog formats. mysql-test/suite/rpl/t/rpl_extraColmaster_innodb.test: Removed triplicate testing and instead relying on test system. Test is only relevant for row format since statement-based replication cannot handle extra columns on master. mysql-test/suite/rpl/t/rpl_extraColmaster_myisam.test: Removed triplicate testing and instead relying on test system. Test is only relevant for row format since statement-based replication cannot handle extra columns on master. mysql-test/suite/rpl/t/rpl_idempotency-slave.opt: Removed .opt file to avoid server restarts. mysql-test/suite/rpl/t/rpl_idempotency.test: - Moved out row-only tests to a new test file, rpl_row_idempotency.test. rpl_idempotency now only contains tests that execute in all binlog_formats. - While I was here, also removed .opt file to avoid server restarts. The slave_exec_mode is now set inside the test instead. mysql-test/suite/rpl/t/rpl_mix_found_rows.test: Split rpl_found_rows.test into rpl_mix_found_rows.test (a new file) and rpl_stm_found_rows.test (renamed rpl_found_rows.test). This file contains the second half of the original rpl_found_rows.test with the follwing changes: - initialization - removed SET_BINLOG_FORMAT and added have_binlog_format_mixed.inc - minor formatting changes mysql-test/suite/rpl/t/rpl_mix_insert_delayed.test: Moved out code operating in mixed mode from rpl_stm_insert_delayed (into rpl_mix_insert_delayed) and got rid of explicit setting of binlog format. mysql-test/suite/rpl/t/rpl_rbr_to_sbr.test: Test cannot execute in statement mode, since we no longer switch to row format when binlog_format=statement. Enforced mixed mode throughout the test. mysql-test/suite/rpl/t/rpl_row_idempotency.test: Moved the second half of rpl_idempotency.test, which only executed in row mode, to this new file. We now rely on the test system to set binlog format. mysql-test/suite/rpl/t/rpl_row_insert_delayed.test: - Got rid of unnecessary explicit setting of binlog format. - extra/rpl_tests/rpl_insert_delayed.test does not need the $binlog_format_statement variable any more, so that was removed. mysql-test/suite/rpl/t/rpl_slave_skip.test: The test switches binlog_format internally and master generates both row and statement events. Hence, the slave must be able to log in both statement and row format. Hence test was changed to only execute in mixed mode. mysql-test/suite/rpl/t/rpl_stm_found_rows.test: Split rpl_found_rows.test into rpl_mix_found_rows.test (a new file) and rpl_stm_found_rows.test (renamed rpl_found_rows.test). Changes in this file: - minor formatting changes - added have_binlog_format_statement and removed SET BINLOG_FORMAT. - second half of file is moved to rpl_mix_found_rows.test - added cleanup code mysql-test/suite/rpl/t/rpl_stm_insert_delayed.test: Moved out code operating in mixed mode from rpl_stm_insert_delayed (into rpl_mix_insert_delayed) and got rid of explicit setting of binlog format. mysql-test/suite/rpl/t/rpl_switch_stm_row_mixed.test: The test switches binlog_format internally and master generates both row and statement events. Hence, the slave must be able to log in both statement and row format. Hence test was changed to only execute in mixed mode on slave. mysql-test/suite/rpl/t/rpl_temporary_errors.test: Removed explicit set of binlog format. Instead, the test now only executes in row mode. mysql-test/suite/rpl/t/rpl_udf.test: Remove explicit set of binlog format (and triplicate test execution) and rely on test system executing the test in all binlog formats. mysql-test/suite/rpl_ndb/combinations: Added combinations file for rpl_ndb. mysql-test/suite/rpl_ndb/r/rpl_ndb_binlog_format_errors.result: new result file mysql-test/suite/rpl_ndb/r/rpl_ndb_circular_simplex.result: updated result file mysql-test/suite/rpl_ndb/t/rpl_ndb_2innodb.test: The test needs slave to be able to switch to row mode, so the test was changed to only execute in mixed and row mode. mysql-test/suite/rpl_ndb/t/rpl_ndb_2myisam.test: The test needs slave to be able to switch to row mode, so the test was changed to only execute in mixed and row mode. mysql-test/suite/rpl_ndb/t/rpl_ndb_basic.test: The test needs slave to be able to switch to row mode, so the test was changed to only execute in mixed and row mode. mysql-test/suite/rpl_ndb/t/rpl_ndb_binlog_format_errors-master.opt: new option file mysql-test/suite/rpl_ndb/t/rpl_ndb_binlog_format_errors-slave.opt: new option file mysql-test/suite/rpl_ndb/t/rpl_ndb_binlog_format_errors.test: New test case to verify all errors and warnings generated by decide_logging_format. mysql-test/suite/rpl_ndb/t/rpl_ndb_blob.test: The test needs slave to be able to switch to row mode, so the test was changed to only execute in mixed and row mode. mysql-test/suite/rpl_ndb/t/rpl_ndb_blob2.test: The test needs slave to be able to switch to row mode, so the test was changed to only execute in mixed and row mode. mysql-test/suite/rpl_ndb/t/rpl_ndb_circular.test: The test needs slave to be able to switch to row mode, so the test was changed to only execute in mixed and row mode. mysql-test/suite/rpl_ndb/t/rpl_ndb_circular_simplex.test: The test needs slave to be able to switch to row mode, so the test was changed to only execute in mixed and row mode. While I was here, also made the test clean up after itself. mysql-test/suite/rpl_ndb/t/rpl_ndb_commit_afterflush.test: The test needs slave to be able to switch to row mode, so the test was changed to only execute in mixed and row mode. mysql-test/suite/rpl_ndb/t/rpl_ndb_ctype_ucs2_def.test: The test needs slave to be able to switch to row mode, so the test was changed to only execute in mixed and row mode. mysql-test/suite/rpl_ndb/t/rpl_ndb_delete_nowhere.test: The test needs slave to be able to switch to row mode, so the test was changed to only execute in mixed and row mode. mysql-test/suite/rpl_ndb/t/rpl_ndb_do_db.test: The test needs slave to be able to switch to row mode, so the test was changed to only execute in mixed and row mode. mysql-test/suite/rpl_ndb/t/rpl_ndb_do_table.test: The test needs slave to be able to switch to row mode, so the test was changed to only execute in mixed and row mode. mysql-test/suite/rpl_ndb/t/rpl_ndb_func003.test: The test needs slave to be able to switch to row mode, so the test was changed to only execute in mixed and row mode. mysql-test/suite/rpl_ndb/t/rpl_ndb_innodb_trans.test: The test needs slave to be able to switch to row mode, so the test was changed to only execute in mixed and row mode. mysql-test/suite/rpl_ndb/t/rpl_ndb_insert_ignore.test: The test needs slave to be able to switch to row mode, so the test was changed to only execute in mixed and row mode. mysql-test/suite/rpl_ndb/t/rpl_ndb_mixed_engines_transactions.test: The test needs slave to be able to switch to row mode, so the test was changed to only execute in mixed and row mode. mysql-test/suite/rpl_ndb/t/rpl_ndb_multi_update3.test: The test needs slave to be able to switch to row mode, so the test was changed to only execute in mixed and row mode. mysql-test/suite/rpl_ndb/t/rpl_ndb_rep_ignore.test: The test needs slave to be able to switch to row mode, so the test was changed to only execute in mixed and row mode. mysql-test/suite/rpl_ndb/t/rpl_ndb_row_001.test: The test needs slave to be able to switch to row mode, so the test was changed to only execute in mixed and row mode. mysql-test/suite/rpl_ndb/t/rpl_ndb_sp003.test: The test needs slave to be able to switch to row mode, so the test was changed to only execute in mixed and row mode. mysql-test/suite/rpl_ndb/t/rpl_ndb_sp006.test: The test needs slave to be able to switch to row mode, so the test was changed to only execute in mixed and row mode. mysql-test/suite/rpl_ndb/t/rpl_ndb_trig004.test: The test needs slave to be able to switch to row mode, so the test was changed to only execute in mixed and row mode. mysql-test/t/partition_innodb_stmt.test: Changed error code for innodb updates with READ COMMITTED or READ UNCOMMITTED transaction isolation level and binlog_format=statement. sql/event_db_repository.cc: Use member function to read current_stmt_binlog_row_based. sql/events.cc: Use member function to read current_stmt_binlog_row_based. sql/ha_ndbcluster_binlog.cc: reset_current_stmt_binlog_row_based() is not a no-op for the ndb_binlog thread any more. Instead, the ndb_binlog thread now forces row mode both initially and just after calling mysql_parse. (mysql_parse() is the only place where reset_current_stmt_binlog_row_based() may be called from the ndb_binlog thread, so these are the only two places that need to change.) sql/ha_partition.cc: Use member function to read current_stmt_binlog_row_based. sql/handler.cc: Use member function to read current_stmt_binlog_row_based. sql/item_create.cc: Added DBUG_ENTER to some functions, to be able to trace when set_stmt_unsafe is called. sql/log.cc: Use member function to read current_stmt_binlog_row_based. sql/log_event.cc: - Moved logic for changing to row format out of do_apply_event (and into decide_logging_format). - Added @todo comment for post-push cleanup. sql/log_event_old.cc: Move logic for changing to row format out of do_apply_event (and into decide_logging_format). sql/mysql_priv.h: Make decide_logging_format() a member of the THD class, for two reasons: - It is natural from an object-oriented perspective. - decide_logging_format() needs to access private members of THD (specifically, the new binlog_warning_flags field). sql/rpl_injector.cc: Removed call to set_current_stmt_binlog_row_based(). From now on, only decide_logging_fromat is allowed to modify current_stmt_binlog_row_based. This call is from the ndb_binlog thread, mostly executing code in ha_ndbcluster_binlog.cc. This call can be safely removed, because: - current_stmt_binlog_row_based is initialized for the ndb_binlog thread's THD object when the THD object is created. So we're not going to read uninitialized memory. - The behavior of ndb_binlog thread does not use the state of the current_stmt_binlog_row_based. It is conceivable that the ndb_binlog thread would rely on the current_stmt_binlog_format in two situations: (1) when it calls mysql_parse; (2) when it calls THD::binlog_query. In case (1), it always clears THD::options&OPTION_BIN_LOG (because run_query() in ha_ndbcluster_binlog.cc is only called with disable_binlogging = TRUE). In case (2), it always uses qtype=STMT_QUERY_TYPE. sql/set_var.cc: Added @todo comment for post-push cleanup. sql/share/errmsg.txt: Added new error messages and clarified ER_BINLOG_UNSAFE_STATEMENT. sql/sp.cc: Added DBUG_ENTER, to be able to trace when set_stmt_unsafe is called. Got rid of MYSQL_QUERY_TYPE: it was equivalent to STMT_QUERY_TYPE. sql/sp_head.cc: Use member function to read current_stmt_binlog_row_based. sql/sp_head.h: Added DBUG_ENTER, to be able to trace when set_stmt_unsafe is called. sql/sql_acl.cc: Got rid of MYSQL_QUERY_TYPE: it was equivalent to STMT_QUERY_TYPE. sql/sql_base.cc: - Made decide_logging_format take care of all logic for deciding the logging format, and for determining the related warnings and errors. See comment above decide_logging_format for details. - Made decide_logging_format a member function of THD, since it needs to access private members of THD and since its purpose is to update the state of a THD object. - Added DBUG_ENTER, to be able to trace when set_stmt_unsafe is called. sql/sql_class.cc: - Moved logic for determining unsafe warnings away from THD::binlog_query (and into decide_logging_format()). Now, it works like this: 1. decide_logging_format detects that the current statement shall produce a warning, if it ever makes it to the binlog 2. decide_logging_format sets a flag of THD::binlog_warning_flags. 3. THD::binlog_query reads the flag. If the flag is set, it generates a warning. - Use member function to read current_stmt_binlog_row_based. sql/sql_class.h: - Added THD::binlog_warning_flags (see sql_class.cc for explanation). - Made decide_logging_format() and reset_for_next_command() member functions of THD (instead of standalone functions). This was needed for two reasons: (1) the functions need to access the private member THD::binlog_warning_flags; (2) the purpose of these functions is to update the staet of a THD object, so from an object-oriented point of view they should be member functions. - Encapsulated current_stmt_binlog_row_based, so it is now private and can only be accessed from a member function. Also changed the data type to an enumeration instead of a bool. - Removed MYSQL_QUERY_TYPE, because it was equivalent to STMT_QUERY_TYPE anyways. - When reset_current_stmt_binlog_row_based was called from the ndb_binlog thread, it would behave as a no-op. This special case has been removed, and the behavior of reset_current_stmt_binlog_row_based does not depend on which thread calls it any more. The special case did not serve any purpose, since the ndb binlog thread did not take the current_stmt_binlog_row_based flag into account anyways. sql/sql_delete.cc: - Moved logic for setting row format for DELETE..LIMIT away from mysql_prepare_delete. (Instead, we mark the statement as unsafe at parse time (sql_yacc.yy) and rely on decide_logging_format() (sql_class.cc) to set row format.) This is part of the fix for BUG#45831. - Use member function to read current_stmt_binlog_row_based. sql/sql_insert.cc: - Removed unnecessary calls to thd->lex->set_stmt_unsafe() and thd->set_current_stmt_binlog_row_based_if_mixed() from handle_delayed_insert(). The calls are unnecessary because they have already been made; they were made in the constructor of the `di' object. - Since decide_logging_format() is now a member function of THD, code that calls decide_logging_format() had to be updated. - Added DBUG_ENTER call, to be able to trace when set_stmt_unsafe is called. - Moved call to set_stmt_unsafe() for INSERT..SELECT..LIMIT away from mysql_insert_select_prepare() (and into decide_logging_format). This is part of the fix for BUG#45831. - Use member function to read current_stmt_binlog_row_based. sql/sql_lex.h: - Added the flag BINLOG_STMT_FLAG_ROW_INJECTION to enum_binlog_stmt_flag. This was necessary so that a statement can identify itself as a row injection. - Added appropriate setter and getter functions for the new flag. - Added or clarified some comments. - Added DBUG_ENTER() sql/sql_load.cc: Use member function to read current_stmt_binlog_row_based. sql/sql_parse.cc: - Made mysql_reset_thd_for_next_command() clear thd->binlog_warning_flags. - Since thd->binlog_warning_flags is private, it must be set in a member function of THD. Hence, moved the body of mysql_reset_thd_for_next_command() to the new member function THD::reset_thd_for_next_command(), and made mysql_reset_thd_for_next_command() call THD::reset_thd_for_next_command(). - Removed confusing comment. - Use member function to read current_stmt_binlog_row_based. sql/sql_repl.cc: Use member function to read current_stmt_binlog_row_based. sql/sql_table.cc: Use member function to read current_stmt_binlog_row_based. sql/sql_udf.cc: Use member function to read current_stmt_binlog_row_based. sql/sql_update.cc: Moved logic for setting row format for UPDATE..LIMIT away from mysql_prepare_update. (Instead, we mark the statement as unsafe at parse time (sql_yacc.yy) and rely on decide_logging_format() (sql_class.cc) to set row format.) This is part of the fix for BUG#45831. sql/sql_yacc.yy: Made INSERT DELAYED, INSERT..SELECT..LIMIT, UPDATE..LIMIT, and DELETE..LIMIT mark themselves as unsafe at parse time (instead of at execution time). This is part of the fixes BUG#45831 and BUG#45825. storage/example/ha_example.cc: Made exampledb accept inserts. This was needed by the new test case rpl_ndb_binlog_format_errors, because it needs an engine that is statement-only (and accepts inserts). storage/example/ha_example.h: Made exampledb a statement-only engine instead of a row-only engine. No existing test relied exampledb's row-only capabilities. The new test case rpl_ndb_binlog_format_errors needs an engine that is statement-only. storage/innobase/handler/ha_innodb.cc: - Changed error error code and message given by innodb when binlog_format=STATEMENT and transaction isolation level is READ COMMITTED or READ UNCOMMITTED. - While I was here, also simplified the condition for checking when to give the error.

BUG#21842 (Cluster fails to replicate to innodb or myisam with err 134 using TPC-B): Problem: A RBR event can contain incomplete row data (only key value and fields which have been changed). In that case, when the row is unpacked into record and written to a table, the missing fields get incorrect NULL values leading to master-slave inconsistency. Solution: Use values found in slave's table for columns which are not given in the rows event. The code for writing a single row uses the following algorithm: 1. unpack row_data into table->record[0], 2. try to insert record, 3. if duplicate record found, fetch it into table->record[0], 4. unpack row_data into table->record[0], 5. write table->record[0] into the table. Where row_data is the row as stored in the data area of a rows event. Thus: a) unpacking of row_data happens at the time when row is written into a table, b) when unpacking (in step 4), only columns present in row_data are overwritten - all other columns remain as they were found in the table. Since all data needed for the above algorithm is stored inside Rows_log_event class, functions which locate and write rows are turned into methods of that class. replace_record() -> Rows_log_event::write_row() find_and_fetch_row() -> Rows_log_event::find_row() Both methods take row data from event's data buffer - the row being processed is pointed by m_curr_row. They unpack the data as needed into table's record buffers record[0] or record[1]. When row is unpacked, m_curr_row_end is set to point at next row in the data buffer. Other changes introduced in this changeset: - Change signature of unpack_row(): don't report errors and don't setup table's rw_set here. Errors can happen only when setting default values in prepare_record() function and are detected there. - In Rows_log_event and derived classes, don't pass arguments to the execution primitives (do_...() member functions) but use class members instead. - Move old row handling code into log_event_old.cc to be used by *_rows_log_event_old classes. Also, a new test rpl_ndb_2other is added which tests basic replication from master using ndb tables to slave storing the same tables using (possibly) different engine (myisam,innodb). Test is based on existing tests rpl_ndb_2myisam and rpl_ndb_2innodb. However, these tests doesn't work for various reasons and currently are disabled (see BUG#19227). The new test differs from the ones it is based on as follows: 1. Single test tests replication with different storage engines on slave (myisam, innodb, ndb). 2. Include file extra/rpl_tests/rpl_ndb_2multi_eng.test containing original tests is replaced by extra/rpl_tests/rpl_ndb_2multi_basic.test which doesn't contain tests using partitioned tables as these don't work currently. Instead, it tests replication to a slave which has more or less columns than master. 3. Include file include/rpl_multi_engine3.inc is replaced with include/rpl_multi_engine2.inc. The later differs by performing slightly different operations (updating more than one row in the table) and clearing table with "TRUNCATE TABLE" statement instead of "DELETE FROM" as replication of "DELETE" doesn't work well in this setting. 4. Slave must use option --log-slave-updates=0 as otherwise execution of replication events generated by ndb fails if table uses a different storage engine on slave (see BUG#29569). sql/log_event.cc: - Initialization of new Rows_log_event members. - Fixing some typos in documentation. In Rows_log_event::do_apply_event: - Set COMPLETE_ROWS_F flag (when master and slave have the same number of columns and all colums are present in the row) - Move initialization of tables write/read sets here, outside the rows processing loop (and out of unpack_row() function). - Remove calls to do_prepare_row() - no longer needed. - Add code managing m_curr_row and m_curr_row_end pointers. - Change signatures of row processing methods of Rows_log_event and it descendants - now most arguments are taken from class members. - Remove do_prepare_row() methods which are no longer used. - The auto_afree_ptr template is moved to rpl_utility.h (so that it can be used in log_event_old.cc). - Removed copy_extra_fields() function - no longer used. In Rows_log_event::write_row (former replace_record): - The old code is moved to log_event_old.cc. - Use prepare_record() and non-destructive unpack_current_row() to fill record with data. - In case a record being inserted already exists on slave and row data is incomplete use the record found and non-destructive unpack_current_row() to combine new column values with existing ones. - More debug info added. In Rows_log_event::find_row (former find_and_fetch_row function): - The old code is moved to log_event_old.cc. - Unpacking of the row is moved here. - In case of search using PK, the key data is prepared here. - More debug info added. - Remove initialization of Rows_log_event::m_after_image buffer which is no longer used. - Use new row unpacking methods in Update_rows_log_event::do_exec_row() to create before and after image. Note: all existing code used by Rows_log_event::do_apply_event() has been moved to log_event_old.cc to be used by *_rows_log_event_old classes. sql/log_event.h: - Add new COMPLETE_ROWS_F flag in Rows_log_event. - Add Rows_log_event members describing the row being processed. - Add a pointer to key buffer which is used in derived classes. - Add new methods: find__row(), write_row() and unpack_current_row(). - Change signatures of do_...() methods (replace method arguments by class members). - Remove do_prepare_row() method which is no longer used. - Update method documentation. - Add Old_rows_log_event class, which contains the old row processing code, as a friend of Rows_log_event so that it can access all members of an event instance. sql/log_event_old.cc: Move here old implementation of Rows_log_event::do_apply_event() and helper methods. sql/log_event_old.h: - Define new class Old_rows_log_event encapsulating old version of Rows_log_event::do_apply_event() and the helper methods. - Add the Old_rows_log_event class as a base for *_old versions of RBR event classes, ensure that the old version of do_apply_event() is called. - For *_old classes, declare the helper methods used in the old version of do_apply_event(). sql/rpl_record.cc: - Make unpack_row non-destructive for columns not present in the row. - Don't fill read/write set here as it is done outside these functions. - Move initialization of a record with default values to a separate function prepare_record(). sql/rpl_record.h: - Change signature of unpack_row(). - Declare function prepare_record(). sql/rpl_utility.cc: Make tabe_def::calc_field_size() a const method. sql/rpl_utility.h: Make table_def::calc_field_size() a const method. Move auto_afree_ptr template here so that it can be re-used (currently in log_event.cc and log_event_old.cc). Similar with DBUG_PRINT_BITSET macro. mysql-test/extra/rpl_tests/rpl_ndb_2multi_basic.test: Modification of rpl_ndb_2multi_eng test. Tests with partitioned tables are removed and a setup with slave having different number of columns than master is added. mysql-test/include/rpl_multi_engine2.inc: Modification of rpl_multi_engine3.inc which operates on more rows and replaces "DELETE FROM t1" with "TRUNCATE TABLE t1" as the first form doesn't replicate in NDB -> non-NDB setting (BUG#28538). mysql-test/suite/rpl_ndb/r/rpl_ndb_2other.result: Results of the test. mysql-test/suite/rpl_ndb/t/rpl_ndb_2other-slave.opt: Test options. --log-slave-updates=0 is compulsory as otherwise non-NDB slave applying row events from NDB master will fail when trying to log them. mysql-test/suite/rpl_ndb/t/rpl_ndb_2other.test: Test replication of NDB table to slave using other engine. The main test is in extra/rpl_tests/rpl_ndb_2multi_basic.test. It is included here several times with different settings of default storage engine on slave.

BUG#36197: flush tables (or little table cache) can cause crash on slave When flushing tables, there were a slight chance that the flush was occuring between processing of two table map events. Since the tables are opened one by one, it might result in that the tables were not valid and that sub- sequent locking of tables would cause the slave to crash. The problem is solved by opening and locking all tables at once using simple_open_n_lock_tables(). Also, the patch contain a change to open_tables() so that pre-locking only takes place when the trg_event_map is not zero, which was not the case before (this caused the lock to be placed in thd->locked_tables instead of thd->lock since the assumption was that triggers would be called later and therefore the tables should be pre-locked). mysql-test/suite/rpl/r/rpl_found_rows.result: Result change mysql-test/suite/rpl/r/rpl_row_inexist_tbl.result: Result change mysql-test/suite/rpl/t/rpl_found_rows.test: Adding drop of table that was created in test. mysql-test/suite/rpl/t/rpl_slave_status.test: Adding waits for slave start and stop to ensure that test works. sql/log_event.cc: Replacing table-by-table open and lock with a single call to simple_open_n_lock_tables(), which in turn required some changes to other code. sql/log_event_old.cc: Replacing table-by-table open and lock with a single call to simple_open_n_lock_tables(), which in turn required some changes to other code. sql/sql_base.cc: Extending check inside open_tables() so that pre-locking in only done if tables->trg_egent_map is non-zero. mysql-test/include/wait_for_slave_sql_to_start.inc: New BitKeeper file ``mysql-test/include/wait_for_slave_sql_to_start.inc''

Include file extra/rpl_tests/rpl_ndb_2multi_eng.test containing original tests is replaced by extra/rpl_tests/rpl_ndb_2multi_basic.test which doesn't contain tests using partitioned tables as these don't work currently. Instead, it tests replication to a slave which has more or less columns than master. 3. Include file include/rpl_multi_engine3.inc is replaced with include/rpl_multi_engine2.inc. The later differs by performing slightly different operations (updating more than one row in the table) and clearing table with "TRUNCATE TABLE" statement instead of "DELETE FROM" as replication of "DELETE" doesn't work well in this setting. 4. Slave must use option --log-slave-updates=0 as otherwise execution of replication events generated by ndb fails if table uses a different storage engine on slave (see BUG#29569). sql/log_event.cc: - Initialization of new Rows_log_event members. - Fixing some typos in documentation. In Rows_log_event::do_apply_event: - Set COMPLETE_ROWS_F flag (when master and slave have the same number of columns and all colums are present in the row) - Move initialization of tables write/read sets here, outside the rows processing loop (and out of unpack_row() function). - Remove calls to do_prepare_row() - no longer needed. - Add code managing m_curr_row and m_curr_row_end pointers. - Change signatures of row processing methods of Rows_log_event and it descendants - now most arguments are taken from class members. - Remove do_prepare_row() methods which are no longer used. - The auto_afree_ptr template is moved to rpl_utility.h (so that it can be used in log_event_old.cc). - Removed copy_extra_fields() function - no longer used. In Rows_log_event::write_row (former replace_record): - The old code is moved to log_event_old.cc. - Use prepare_record() and non-destructive unpack_current_row() to fill record with data. - In case a record being inserted already exists on slave and row data is incomplete use the record found and non-destructive unpack_current_row() to combine new column values with existing ones. - More debug info added.

BUG#36197: flush tables (or little table cache) can cause crash on slave When flushing tables, there were a slight chance that the flush was occuring between processing of two table map events. Since the tables are opened one by one, it might result in that the tables were not valid and that sub- sequent locking of tables would cause the slave to crash. The problem is solved by opening and locking all tables at once using simple_open_n_lock_tables(). Also, the patch contain a change to open_tables() so that pre-locking only takes place when the trg_event_map is not zero, which was not the case before (this caused the lock to be placed in thd->locked_tables instead of thd->lock since the assumption was that triggers would be called later and therefore the tables should be pre-locked). mysql-test/suite/rpl/r/rpl_found_rows.result: Result change mysql-test/suite/rpl/r/rpl_row_inexist_tbl.result: Result change mysql-test/suite/rpl/t/rpl_found_rows.test: Adding drop of table that was created in test. mysql-test/suite/rpl/t/rpl_slave_status.test: Adding waits for slave start and stop to ensure that test works. sql/log_event.cc: Replacing table-by-table open and lock with a single call to simple_open_n_lock_tables(), which in turn required some changes to other code. sql/log_event_old.cc: Replacing table-by-table open and lock with a single call to simple_open_n_lock_tables(), which in turn required some changes to other code. sql/sql_base.cc: Extending check inside open_tables() so that pre-locking in only done if tables->trg_egent_map is non-zero. mysql-test/include/wait_for_slave_sql_to_start.inc: New BitKeeper file ``mysql-test/include/wait_for_slave_sql_to_start.inc''

BUG#21842 (Cluster fails to replicate to innodb or myisam with err 134 using TPC-B): Problem: A RBR event can contain incomplete row data (only key value and fields which have been changed). In that case, when the row is unpacked into record and written to a table, the missing fields get incorrect NULL values leading to master-slave inconsistency. Solution: Use values found in slave's table for columns which are not given in the rows event. The code for writing a single row uses the following algorithm: 1. unpack row_data into table->record[0], 2. try to insert record, 3. if duplicate record found, fetch it into table->record[0], 4. unpack row_data into table->record[0], 5. write table->record[0] into the table. Where row_data is the row as stored in the data area of a rows event. Thus: a) unpacking of row_data happens at the time when row is written into a table, b) when unpacking (in step 4), only columns present in row_data are overwritten - all other columns remain as they were found in the table. Since all data needed for the above algorithm is stored inside Rows_log_event class, functions which locate and write rows are turned into methods of that class. replace_record() -> Rows_log_event::write_row() find_and_fetch_row() -> Rows_log_event::find_row() Both methods take row data from event's data buffer - the row being processed is pointed by m_curr_row. They unpack the data as needed into table's record buffers record[0] or record[1]. When row is unpacked, m_curr_row_end is set to point at next row in the data buffer. Other changes introduced in this changeset: - Change signature of unpack_row(): don't report errors and don't setup table's rw_set here. Errors can happen only when setting default values in prepare_record() function and are detected there. - In Rows_log_event and derived classes, don't pass arguments to the execution primitives (do_...() member functions) but use class members instead. - Move old row handling code into log_event_old.cc to be used by *_rows_log_event_old classes. Also, a new test rpl_ndb_2other is added which tests basic replication from master using ndb tables to slave storing the same tables using (possibly) different engine (myisam,innodb). Test is based on existing tests rpl_ndb_2myisam and rpl_ndb_2innodb. However, these tests doesn't work for various reasons and currently are disabled (see BUG#19227).

BUG#31581: 5.1-telco-6.1 -> 5.1.22. Slave crashes during starting This patch has two purposes: (1) To refactor the code so that {Write|Update|Delete}_rows_log_event_old does not use code from {Write|Update|Delete}_rows_log_event. Before refactoring there was the following problem: whenever we modifed the code for new events, it affected the old events. This is bad, as it makes maintainance difficult. After refactoring, we can safely edit the new code without affecting old events. So, if we for instance modify the binary format of new events, we no longer need to worry about how the new code reads old events. (2) To fix BUG#31581. These two objectives are reached by the following changes: - Merged Rows_log_event into Old_rows_log_event and {Write|Update|Delete}_rows_log_event into {Write|Update|Delete}_rows_log_event_old. - Fixed the bug by replacing {WRITE|UPDATE|DELETE}_ROWS_EVENT by PRE_GA_{WRITE|UPDATE|DELETE}_ROWS_EVENT. - Added comments to log_event_old.h (This patch is identical to the previously committed patch which was a collapse of three changesets, except that it adds assert(0) to constructors for old types of row log events that should never be called.) sql/log_event_old.cc: Merged Rows_log_event into Old_rows_log_event and {Write|Update|Delete}_rows_log_event into {Write|Update|Delete}_rows_log_event_old. Also fixed the bug by replacing {WRITE|UPDATE|DELETE}_ROWS_EVENT by PRE_GA_{WRITE|UPDATE|DELETE}_ROWS_EVENT. sql/log_event_old.h: Merged Rows_log_event into Old_rows_log_event and {Write|Update|Delete}_rows_log_event into {Write|Update|Delete}_rows_log_event_old. Also added comment explaining what the file contains and what the classes do.

They unpack the data as needed into table's record buffers record[0] or record[1]. When row is unpacked, m_curr_row_end is set to point at next row in the data buffer. Other changes introduced in this changeset: - Change signature of unpack_row(): don't report errors and don't setup table's rw_set here. Errors can happen only when setting default values in prepare_record() function and are detected there. - In Rows_log_event and derived classes, don't pass arguments to the execution primitives (do_...() member functions) but use class members instead. - Move old row handling code into log_event_old.cc to be used by *_rows_log_event_old classes. Also, a new test rpl_ndb_2other is added which tests basic replication from master using ndb tables to slave storing the same tables using (possibly) different engine (myisam,innodb). Test is based on existing tests rpl_ndb_2myisam and rpl_ndb_2innodb. However, these tests doesn't work for various reasons and currently are disabled (see BUG#19227). The new test differs from the ones it is based on as follows: 1. Single test tests replication with different storage engines on slave (myisam, innodb, ndb). 2. Include file extra/rpl_tests/rpl_ndb_2multi_eng.test containing original tests is replaced by extra/rpl_tests/rpl_ndb_2multi_basic.test which doesn't contain tests using partitioned tables as these don't work currently. Instead, it tests replication to a slave which has more or less columns than master. 3. Include file include/rpl_multi_engine3.inc is replaced with include/rpl_multi_engine2.inc. The later differs by performing slightly different operations (updating more than one row in the table) and clearing table with "TRUNCATE TABLE" statement instead of "DELETE FROM" as replication of "DELETE" doesn't work well in this setting. 4. Slave must use option --log-slave-updates=0 as otherwise execution of replication events generated by ndb fails if table uses a different storage engine on slave (see BUG#29569). sql/log_event.cc: - Initialization of new Rows_log_event members. - Fixing some typos in documentation. In Rows_log_event::do_apply_event: - Set COMPLETE_ROWS_F flag (when master and slave have the same number of columns and all colums are present in the row) - Move initialization of tables write/read sets here, outside the rows processing loop (and out of unpack_row() function). - Remove calls to do_prepare_row() - no longer needed. - Add code managing m_curr_row and m_curr_row_end pointers. - Change signatures of row processing methods of Rows_log_event and it descendants - now most arguments are taken from class members. - Remove do_prepare_row() methods which are no longer used. - The auto_afree_ptr template is moved to rpl_utility.h (so that it can be used in log_event_old.cc). - Removed copy_extra_fields() function - no longer used. In Rows_log_event::write_row (former replace_record): - The old code is moved to log_event_old.cc. - Use prepare_record() and non-destructive unpack_current_row() to fill record with data. - In case a record being inserted already exists on slave and row data is incomplete use the record found and non-destructive unpack_current_row() to combine new column values with existing ones. - More debug info added. In Rows_log_event::find_row (former find_and_fetch_row function): - The old code is moved to log_event_old.cc. - Unpacking of the row is moved here. - In case of search using PK, the key data is prepared here. - More debug info added. - Remove initialization of Rows_log_event::m_after_image buffer which is no longer used. - Use new row unpacking methods in Update_rows_log_event::do_exec_row() to create before and after image. Note: all existing code used by Rows_log_event::do_apply_event() has been moved to log_event_old.cc to be used by *_rows_log_event_old classes. sql/log_event.h: - Add new COMPLETE_ROWS_F flag in Rows_log_event. - Add Rows_log_event members describing the row being processed. - Add a pointer to key buffer which is used in derived classes. - Add new methods: find__row(), write_row() and unpack_current_row(). - Change signatures of do_...() methods (replace method arguments by class members). - Remove do_prepare_row() method which is no longer used. - Update method documentation. - Add Old_rows_log_event class, which contains the old row processing code, as a friend of Rows_log_event so that it can access all members of an event instance. sql/log_event_old.cc: Move here old implementation of Rows_log_event::do_apply_event() and helper methods. sql/log_event_old.h: - Define new class Old_rows_log_event encapsulating old version of Rows_log_event::do_apply_event() and the helper methods. - Add the Old_rows_log_event class as a base for *_old versions of RBR event classes, ensure that the old version of do_apply_event() is called. - For *_old classes, declare the helper methods used in the old version of do_apply_event(). sql/rpl_record.cc: - Make unpack_row non-destructive for columns not present in the row. - Don't fill read/write set here as it is done outside these functions. - Move initialization of a record with default values to a separate function prepare_record(). sql/rpl_record.h: - Change signature of unpack_row(). - Declare function prepare_record(). sql/rpl_utility.cc: Make tabe_def::calc_field_size() a const method. sql/rpl_utility.h: Make table_def::calc_field_size() a const method. Move auto_afree_ptr template here so that it can be re-used (currently in log_event.cc and log_event_old.cc).

Tests with partitioned tables are removed and a setup with slave having different number of columns than master is added. mysql-test/include/rpl_multi_engine2.inc: Modification of rpl_multi_engine3.inc which operates on more rows and replaces "DELETE FROM t1" with "TRUNCATE TABLE t1" as the first form doesn't replicate in NDB -> non-NDB setting (BUG#28538). mysql-test/suite/rpl_ndb/r/rpl_ndb_2other.result: Results of the test. mysql-test/suite/rpl_ndb/t/rpl_ndb_2other-slave.opt: Test options. --log-slave-updates=0 is compulsory as otherwise non-NDB slave applying row events from NDB master will fail when trying to log them. mysql-test/suite/rpl_ndb/t/rpl_ndb_2other.test: Test replication of NDB table to slave using other engine.

BUG#31581: 5.1-telco-6.1 -> 5.1.22. Slave crashes during starting This patch has two purposes: (1) To refactor the code so that {Write|Update|Delete}_rows_log_event_old does not use code from {Write|Update|Delete}_rows_log_event. Before refactoring there was the following problem: whenever we modifed the code for new events, it affected the old events. This is bad, as it makes maintainance difficult. After refactoring, we can safely edit the new code without affecting old events. So, if we for instance modify the binary format of new events, we no longer need to worry about how the new code reads old events. (2) To fix BUG#31581. These two objectives are reached by the following changes: - Merged Rows_log_event into Old_rows_log_event and {Write|Update|Delete}_rows_log_event into {Write|Update|Delete}_rows_log_event_old. - Fixed the bug by replacing {WRITE|UPDATE|DELETE}_ROWS_EVENT by PRE_GA_{WRITE|UPDATE|DELETE}_ROWS_EVENT. - Added comments to log_event_old.h (This patch is identical to the previously committed patch which was a collapse of three changesets, except that it adds assert(0) to constructors for old types of row log events that should never be called.) sql/log_event_old.cc: Merged Rows_log_event into Old_rows_log_event and {Write|Update|Delete}_rows_log_event into {Write|Update|Delete}_rows_log_event_old. Also fixed the bug by replacing {WRITE|UPDATE|DELETE}_ROWS_EVENT by PRE_GA_{WRITE|UPDATE|DELETE}_ROWS_EVENT. sql/log_event_old.h: Merged Rows_log_event into Old_rows_log_event and {Write|Update|Delete}_rows_log_event into {Write|Update|Delete}_rows_log_event_old. Also added comment explaining what the file contains and what the classes do.

BUG#21842 (Cluster fails to replicate to innodb or myisam with err 134 using TPC-B): Problem: A RBR event can contain incomplete row data (only key value and fields which have been changed). In that case, when the row is unpacked into record and written to a table, the missing fields get incorrect NULL values leading to master-slave inconsistency. Solution: Use values found in slave's table for columns which are not given in the rows event. The code for writing a single row uses the following algorithm: 1. unpack row_data into table->record[0], 2. try to insert record, 3. if duplicate record found, fetch it into table->record[0], 4. unpack row_data into table->record[0], 5. write table->record[0] into the table.

BUG#31581: 5.1-telco-6.1 -> 5.1.22. Slave crashes during starting This patch has two purposes: (1) To refactor the code so that {Write|Update|Delete}_rows_log_event_old does not use code from {Write|Update|Delete}_rows_log_event. Before refactoring there was the following problem: whenever we modifed the code for new events, it affected the old events. This is bad, as it makes maintainance difficult. After refactoring, we can safely edit the new code without affecting old events. So, if we for instance modify the binary format of new events, we no longer need to worry about how the new code reads old events. (2) To fix BUG#31581. These two objectives are reached by the following changes: - Merged Rows_log_event into Old_rows_log_event and {Write|Update|Delete}_rows_log_event into {Write|Update|Delete}_rows_log_event_old. - Fixed the bug by replacing {WRITE|UPDATE|DELETE}_ROWS_EVENT by PRE_GA_{WRITE|UPDATE|DELETE}_ROWS_EVENT. - Added comments to log_event_old.h (This patch is identical to the previously committed patch which was a collapse of three changesets, except that it adds assert(0) to constructors for old types of row log events that should never be called.) sql/log_event_old.cc: Merged Rows_log_event into Old_rows_log_event and {Write|Update|Delete}_rows_log_event into {Write|Update|Delete}_rows_log_event_old.

BUG#21842 (Cluster fails to replicate to innodb or myisam with err 134 using TPC-B): Problem: A RBR event can contain incomplete row data (only key value and fields which have been changed). In that case, when the row is unpacked into record and written to a table, the missing fields get incorrect NULL values leading to master-slave inconsistency. Solution: Use values found in slave's table for columns which are not given in the rows event. The code for writing a single row uses the following algorithm: 1. unpack row_data into table->record[0], 2. try to insert record, 3. if duplicate record found, fetch it into table->record[0], 4. unpack row_data into table->record[0], 5. write table->record[0] into the table. Where row_data is the row as stored in the data area of a rows event. Thus: a) unpacking of row_data happens at the time when row is written into a table, b) when unpacking (in step 4), only columns present in row_data are overwritten - all other columns remain as they were found in the table. Since all data needed for the above algorithm is stored inside Rows_log_event class, functions which locate and write rows are turned into methods of that class. replace_record() -> Rows_log_event::write_row() find_and_fetch_row() -> Rows_log_event::find_row() Both methods take row data from event's data buffer - the row being processed is pointed by m_curr_row. They unpack the data as needed into table's record buffers record[0] or record[1]. When row is unpacked, m_curr_row_end is set to point at next row in the data buffer. Other changes introduced in this changeset: - Change signature of unpack_row(): don't report errors and don't setup table's rw_set here. Errors can happen only when setting default values in prepare_record() function and are detected there. - In Rows_log_event and derived classes, don't pass arguments to the execution primitives (do_...() member functions) but use class members instead. - Move old row handling code into log_event_old.cc to be used by *_rows_log_event_old classes. Also, a new test rpl_ndb_2other is added which tests basic replication from master using ndb tables to slave storing the same tables using (possibly) different engine (myisam,innodb). Test is based on existing tests rpl_ndb_2myisam and rpl_ndb_2innodb. However, these tests doesn't work for various reasons and currently are disabled (see BUG#19227). The new test differs from the ones it is based on as follows: 1. Single test tests replication with different storage engines on slave (myisam, innodb, ndb). 2. Include file extra/rpl_tests/rpl_ndb_2multi_eng.test containing original tests is replaced by extra/rpl_tests/rpl_ndb_2multi_basic.test which doesn't contain tests using partitioned tables as these don't work currently. Instead, it tests replication to a slave which has more or less columns than master. 3. Include file include/rpl_multi_engine3.inc is replaced with include/rpl_multi_engine2.inc.

In Rows_log_event::do_apply_event: - Set COMPLETE_ROWS_F flag (when master and slave have the same number of columns and all colums are present in the row) - Move initialization of tables write/read sets here, outside the rows processing loop (and out of unpack_row() function). - Remove calls to do_prepare_row() - no longer needed. - Add code managing m_curr_row and m_curr_row_end pointers. - Change signatures of row processing methods of Rows_log_event and it descendants - now most arguments are taken from class members. - Remove do_prepare_row() methods which are no longer used. - The auto_afree_ptr template is moved to rpl_utility.h (so that it can be used in log_event_old.cc). - Removed copy_extra_fields() function - no longer used. In Rows_log_event::write_row (former replace_record): - The old code is moved to log_event_old.cc. - Use prepare_record() and non-destructive unpack_current_row() to fill record with data. - In case a record being inserted already exists on slave and row data is incomplete use the record found and non-destructive unpack_current_row() to combine new column values with existing ones. - More debug info added.

Note: all existing code used by Rows_log_event::do_apply_event() has been moved to log_event_old.cc to be used by *_rows_log_event_old classes. sql/log_event.h: - Add new COMPLETE_ROWS_F flag in Rows_log_event. - Add Rows_log_event members describing the row being processed. - Add a pointer to key buffer which is used in derived classes. - Add new methods: find__row(), write_row() and unpack_current_row(). - Change signatures of do_...() methods (replace method arguments by class members). - Remove do_prepare_row() method which is no longer used. - Update method documentation. - Add Old_rows_log_event class, which contains the old row processing code, as a friend of Rows_log_event so that it can access all members of an event instance. sql/log_event_old.cc: Move here old implementation of Rows_log_event::do_apply_event() and helper methods. sql/log_event_old.h: - Define new class Old_rows_log_event encapsulating old version of Rows_log_event::do_apply_event() and the helper methods. - Add the Old_rows_log_event class as a base for *_old versions of RBR event classes, ensure that the old version of do_apply_event() is called. - For *_old classes, declare the helper methods used in the old version of do_apply_event(). sql/rpl_record.cc: - Make unpack_row non-destructive for columns not present in the row. - Don't fill read/write set here as it is done outside these functions. - Move initialization of a record with default values to a separate function prepare_record(). sql/rpl_record.h: - Change signature of unpack_row(). - Declare function prepare_record(). sql/rpl_utility.cc: Make tabe_def::calc_field_size() a const method. sql/rpl_utility.h: Make table_def::calc_field_size() a const method.

Bug#12713 "Error in a stored function called from a SELECT doesn't cause ROLLBACK of statement", part 1. Review fixes. Do not send OK/EOF packets to the client until we reached the end of the current statement. This is a consolidation, to keep the functionality that is shared by all SQL statements in one place in the server. Currently this functionality includes: - close_thread_tables() - log_slow_statement(). After this patch and the subsequent patch for Bug#12713, it shall also include: - ha_autocommit_or_rollback() - net_end_statement() - query_cache_end_of_result(). In future it may also include: - mysql_reset_thd_for_next_command(). include/mysql_com.h: Rename now unused members of NET: no_send_ok, no_send_error, report_error. These were server-specific variables related to the client/server protocol. They have been made obsolete by this patch. Previously the same members of NET were used to store the error message both on the client and on the server. The error message was stored in net.last_error (client: mysql->net.last_error, server: thd->net.last_error). The error code was stored in net.last_errno (client: mysql->net.last_errno, server: thd->net.last_errno). The server error code and message are now stored elsewhere (in the Diagnostics_area), thus NET members are no longer used by the server. Rename last_error to client_last_error, last_errno to client_last_errno to avoid potential bugs introduced by merges. include/mysql_h.ic: Update the ABI file to reflect a rename. Renames do not break the binary compatibility. libmysql/libmysql.c: Rename last_error to client_last_error, last_errno to client_last_errno. This is necessary to ensure no unnoticed bugs introduced by merged changesets. Remove net.report_error, net.no_send_ok, net.no_send_error. libmysql/manager.c: Rename net.last_errno to net.client_last_errno. libmysqld/lib_sql.cc: Rename net.last_errno to net.client_last_errno. Update the embedded implementation of the client-server protocol to reflect the refactoring of protocol.cc. libmysqld/libmysqld.c: Rename net.last_errno to net.client_last_errno. mysql-test/r/events.result: Update to reflect the change in mysql_rm_db(). Now we drop stored routines and events for a given database name only if there is a directory for this database name. ha_drop_database() and query_cache_invalidate() are called likewise. Previously we would attempt to drop routines/events even if database directory was not found (it worked, since routines and events are stored in tables). This fixes Bug 29958 "Weird message on DROP DATABASE if mysql.proc does not exist". The change was done because the previous code used to call send_ok() twice, which led to an assertion failure when asserts against it were added by this patch. mysql-test/r/grant.result: Fix the patch for Bug 16470, now FLUSH PRIVILEGES produces an error if mysql.procs_priv is missing. This fixes the assert that send_ok() must not called after send_error() (the original patch for Bug 16470 was prone to this). mysql-test/suite/rpl/r/rpl_row_tabledefs_2myisam.result: Produce a more detailed error message. mysql-test/suite/rpl/r/rpl_row_tabledefs_3innodb.result: Produce a more detailed error message. mysql-test/t/grant.test: Update the test, now FLUSH PRIVILEGES returns an error if mysql.procs_priv is missing. server-tools/instance-manager/mysql_connection.cc: Rename net.last_errno to net.client_last_errno. sql/ha_ndbcluster_binlog.cc: Add asserts. Use getters to access statement status information. Add a comment why run_query() is broken. Reset the diagnostics area in the end of run_query() to fulfill the invariant that the diagnostics_area is never assigned twice per statement (see the comment in the code when this can happen). We still do not clear thd->is_fatal_error and thd->is_slave_error, which may lead to bugs, I consider the whole affair as something to be dealt with separately. sql/ha_partition.cc: fatal_error() doesn't set an error by itself. Perhaps we should remove this method altogether and instead add a flag to my_error to set thd->is_fatal_error property. Meanwhile, this change is a part of inspection made to the entire source code with the goal to ensure that fatal_error() is always accompanied by my_error(). sql/item_func.cc: There is no net.last_error anymore. Remove the obsolete assignment. sql/log_event.cc: Use getters to access statement error status information. sql/log_event_old.cc: Use getters to access statement error status information. sql/mysqld.cc: Previously, if a continue handler for an error was found, my_message_sql() would not set an error in THD. Since the current statement must be aborted in any case, find_handler() had a hack to assign thd->net.report_error to 1. Remove this hack. Set an error in my_message_sql() even if the continue handler is found. The error will be cleared anyway when the handler is executed. This is one action among many in this patch to ensure the invariant that whenever thd->is_error() is TRUE, we have a message in thd->main_da.message(). sql/net_serv.cc: Use a full-blown my_error() in net_serv.cc to report an error, instead of just setting net->last_errno. This ensures the invariant that whenever thd->is_error() returns TRUE, we have a message in thd->main_da.message(). Remove initialization of removed NET members. sql/opt_range.cc: Use my_error() instead of just raising thd->net.report_error. This ensures the invariant that whenever thd->is_error() returns TRUE, there is a message in thd->main_da.message(). sql/opt_sum.cc: Move invocation of fatal_error() right next to the place where we set the error message. That makes it easier to track that whenever fatal_error() is called, there is a message in THD. sql/protocol.cc: Rename send_ok() and send_eof() to net_send_ok() and net_send_eof() respectively. These functions write directly to the network and are not for use anywhere outside the client/server protocol code. Remove the code that was responsible for cases when either there is no error code, or no error message, or both. Instead the calling code ensures that they are always present. Asserts are added to enforce the invariant. Instead of a direct access to thd->server_status and thd->total_warn_count use function parameters, since these from now on don't always come directly from THD. Introduce net_end_statement(), the single-entry-point replacement API for send_ok(), send_eof() and net_send_error(). Implement Protocol::end_partial_result_set to use in select_send::abort() when there is a continue handler. sql/protocol.h: Update declarations. sql/repl_failsafe.cc: Use getters to access statement status information in THD. Rename net.last_error to net.client_last_error. sql/rpl_record.cc: Set an error message in prepare_record() if there is no default value for the field -- later we do print this message to the client. sql/rpl_rli.cc: Use getters to access statement status information in THD. sql/slave.cc: In create_table_from_dump() (a common function that is used in LOAD MASTER TABLE SQL statement and COM_LOAD_MASTER_DATA), instead of hacks with no_send_ok, clear the diagnostics area when mysql_rm_table() succeeded. Update has_temporary_error() to work correctly when no error is set. This is the case when Incident_log_event is executed: it always returns an error but does not set an error message. Use getters to access error status information. sql/sp_head.cc: Instead of hacks with no_send_error, work through the diagnostics area interface to suppress sending of OK/ERROR packets to the client. Move query_cache_end_of_result before log_slow_statement(), similarly to how it's done in dispatch_command(). sql/sp_rcontext.cc: Remove hacks with assignment of thd->net.report_error, they are not necessary any more (see the changes in mysqld.cc). sql/sql_acl.cc: Use getters to access error status information in THD. sql/sql_base.cc: Access thd->main_da.sql_errno() only if there is an error. This fixes a bug when auto-discovery, that was effectively disabled under pre-locking. sql/sql_binlog.cc: Remove hacks with no_send_ok/no_send_error, they are not necessary anymore: the caller is responsible for network communication. sql/sql_cache.cc: Disable sending of OK/ERROR/EOF packet in the end of dispatch_command if the response has been served from the query cache. This raises the question whether we should store EOF packet in the query cache at all, or generate it anew for each statement (we should generate it anew), but this is to be addressed separately. sql/sql_class.cc: Implement class Diagnostics_area. Please see comments in sql_class.h for details. Fix a subtle coding mistake in select_send::send_data: when on slave, an error in Item::send() was ignored. The problem became visible due to asserts that the diagnostics area is never double assigned. Remove initialization of removed NET members. In select_send::abort() do not call select_send::send_eof(). This is not inheritance-safe. Even if a stored procedure continue handler is found, the current statement is aborted, not succeeded. Instead introduce a Protocol API to send the required response, Protocol::end_partial_result_set(). This simplifies implementation of select_send::send_eof(). No need to add more asserts that there is no error, there is an assert inside Diagnostics_area::set_ok_status() already. Leave no trace of no_send_* in the code. sql/sql_class.h: Declare class Diagnostics_area. Remove the hack with no_send_ok from Substatement_state. Provide inline implementations of send_ok/send_eof. Add commetns. sql/sql_connect.cc: Remove hacks with no_send_error. Since now an error in THD is always set if net->error, it's not necessary to check both net->error and thd->is_error() in the do_command loop. Use thd->main_da.message() instead of net->last_errno. Remove the hack with is_slave_error in sys_init_connect. Since now we do not reset the diagnostics area in net_send_error (it's reset at the beginning of the next statement), we can access it safely even after execute_init_command. sql/sql_db.cc: Update the code to satisfy the invariant that the diagnostics area is never assigned twice. Incidentally, this fixes Bug 29958 "Weird message on DROP DATABASE if mysql.proc does not exist". sql/sql_delete.cc: Change multi-delete to abort in abort(), as per select_send protocol. Fixes the merge error with the test for Bug 29136 sql/sql_derived.cc: Use getters to access error information. sql/sql_insert.cc: Use getters to access error information. sql-common/client.c: Rename last_error to client_last_error, last_errno to client_last_errno. sql/sql_parse.cc: Remove hacks with no_send_error. Deploy net_end_statement(). The story of COM_SHUTDOWN is interesting. Long story short, the server would become on its death's door, and only no_send_ok/no_send_error assigned by send_ok()/net_send_error() would hide its babbling from the client. First of all, COM_QUIT does not require a response. So, the comment saying "Let's send a response to possible COM_QUIT" is not only groundless (even mysqladmin shutdown/mysql_shutdown() doesn't send COM_QUIT after COM_SHUTDOWN), it's plainly incorrect. Secondly, besides this additional 'OK' packet to respond to a hypothetical COM_QUIT, there was the following code in dispatch_command(): if (thd->killed) thd->send_kill_message(); if (thd->is_error() net_send_error(thd); This worked out really funny for the thread through which COM_SHUTDOWN was delivered: we would get COM_SHUTDOWN, say okay, say okay again, kill everybody, get the kill signal ourselves, and then attempt to say "Server shutdown in progress" to the client that is very likely long gone. This all became visible when asserts were added that the Diagnostics_area is not assigned twice. Move query_cache_end_of_result() to the end of dispatch_command(), since net_send_eof() has been moved there. This is safe, query_cache_end_of_result() is a no-op if there is no started query in the cache. Consistently use select_send interface to call abort() or send_eof() depending on the operation result. Remove thd->fatal_error() from reset_master(), it was a no-op. in hacks with no_send_error woudl save us from complete breakage of the client/server protocol. Consistently use select_send::abort() whenever there is an error, and select_send::send_eof() in case of success. The issue became visible due to added asserts. sql/sql_partition.cc: Always set an error in THD whenever there is a call to fatal_error(). sql/sql_prepare.cc: Deploy class Diagnostics_area. Remove the unnecessary juggling with the protocol in Select_fetch_protocol_binary::send_eof(). EOF packet format is protocol-independent. sql/sql_select.cc: Call fatal_error() directly in opt_sum_query. Call my_error() whenever we call thd->fatal_error(). sql/sql_servers.cc: Use getters to access error information in THD. sql/sql_show.cc: Use getters to access error information in THD. Add comments. Call my_error() whenever we call fatal_error(). sql/sql_table.cc: Replace hacks with no_send_ok with the interface of the diagnostics area. Clear the error if ENOENT error in ha_delete_table(). sql/sql_update.cc: Introduce multi_update::abort(), which is the proper way to abort a multi-update. This fixes the merge conflict between this patch and the patch for Bug 29136. sql/table.cc: Use a getter to access error information in THD. sql/tztime.cc: Use a getter to access error information in THD.

rli->report(ERROR_LEVEL, thd->main_da.sql_errno(),
BUG#21842 (Cluster fails to replicate to innodb or myisam with err 134 using TPC-B): Problem: A RBR event can contain incomplete row data (only key value and fields which have been changed). In that case, when the row is unpacked into record and written to a table, the missing fields get incorrect NULL values leading to master-slave inconsistency. Solution: Use values found in slave's table for columns which are not given in the rows event. The code for writing a single row uses the following algorithm: 1. unpack row_data into table->record[0], 2. try to insert record, 3. if duplicate record found, fetch it into table->record[0], 4. unpack row_data into table->record[0], 5. write table->record[0] into the table. Where row_data is the row as stored in the data area of a rows event. Thus: a) unpacking of row_data happens at the time when row is written into a table, b) when unpacking (in step 4), only columns present in row_data are overwritten - all other columns remain as they were found in the table. Since all data needed for the above algorithm is stored inside Rows_log_event class, functions which locate and write rows are turned into methods of that class. replace_record() -> Rows_log_event::write_row() find_and_fetch_row() -> Rows_log_event::find_row() Both methods take row data from event's data buffer - the row being processed is pointed by m_curr_row. They unpack the data as needed into table's record buffers record[0] or record[1]. When row is unpacked, m_curr_row_end is set to point at next row in the data buffer. Other changes introduced in this changeset: - Change signature of unpack_row(): don't report errors and don't setup table's rw_set here. Errors can happen only when setting default values in prepare_record() function and are detected there. - In Rows_log_event and derived classes, don't pass arguments to the execution primitives (do_...() member functions) but use class members instead. - Move old row handling code into log_event_old.cc to be used by *_rows_log_event_old classes. Also, a new test rpl_ndb_2other is added which tests basic replication from master using ndb tables to slave storing the same tables using (possibly) different engine (myisam,innodb). Test is based on existing tests rpl_ndb_2myisam and rpl_ndb_2innodb. However, these tests doesn't work for various reasons and currently are disabled (see BUG#19227). The new test differs from the ones it is based on as follows: 1. Single test tests replication with different storage engines on slave (myisam, innodb, ndb). 2. Include file extra/rpl_tests/rpl_ndb_2multi_eng.test containing original tests is replaced by extra/rpl_tests/rpl_ndb_2multi_basic.test which doesn't contain tests using partitioned tables as these don't work currently. Instead, it tests replication to a slave which has more or less columns than master. 3. Include file include/rpl_multi_engine3.inc is replaced with include/rpl_multi_engine2.inc. The later differs by performing slightly different operations (updating more than one row in the table) and clearing table with "TRUNCATE TABLE" statement instead of "DELETE FROM" as replication of "DELETE" doesn't work well in this setting. 4. Slave must use option --log-slave-updates=0 as otherwise execution of replication events generated by ndb fails if table uses a different storage engine on slave (see BUG#29569). sql/log_event.cc: - Initialization of new Rows_log_event members. - Fixing some typos in documentation. In Rows_log_event::do_apply_event: - Set COMPLETE_ROWS_F flag (when master and slave have the same number of columns and all colums are present in the row) - Move initialization of tables write/read sets here, outside the rows processing loop (and out of unpack_row() function). - Remove calls to do_prepare_row() - no longer needed. - Add code managing m_curr_row and m_curr_row_end pointers. - Change signatures of row processing methods of Rows_log_event and it descendants - now most arguments are taken from class members. - Remove do_prepare_row() methods which are no longer used. - The auto_afree_ptr template is moved to rpl_utility.h (so that it can be used in log_event_old.cc). - Removed copy_extra_fields() function - no longer used. In Rows_log_event::write_row (former replace_record): - The old code is moved to log_event_old.cc. - Use prepare_record() and non-destructive unpack_current_row() to fill record with data. - In case a record being inserted already exists on slave and row data is incomplete use the record found and non-destructive unpack_current_row() to combine new column values with existing ones. - More debug info added.

Note: all existing code used by Rows_log_event::do_apply_event() has been moved to log_event_old.cc to be used by *_rows_log_event_old classes. sql/log_event.h: - Add new COMPLETE_ROWS_F flag in Rows_log_event. - Add Rows_log_event members describing the row being processed. - Add a pointer to key buffer which is used in derived classes. - Add new methods: find__row(), write_row() and unpack_current_row(). - Change signatures of do_...() methods (replace method arguments by class members). - Remove do_prepare_row() method which is no longer used. - Update method documentation. - Add Old_rows_log_event class, which contains the old row processing code, as a friend of Rows_log_event so that it can access all members of an event instance. sql/log_event_old.cc: Move here old implementation of Rows_log_event::do_apply_event() and helper methods. sql/log_event_old.h: - Define new class Old_rows_log_event encapsulating old version of Rows_log_event::do_apply_event() and the helper methods. - Add the Old_rows_log_event class as a base for *_old versions of RBR event classes, ensure that the old version of do_apply_event() is called. - For *_old classes, declare the helper methods used in the old version of do_apply_event(). sql/rpl_record.cc: - Make unpack_row non-destructive for columns not present in the row. - Don't fill read/write set here as it is done outside these functions. - Move initialization of a record with default values to a separate function prepare_record(). sql/rpl_record.h: - Change signature of unpack_row(). - Declare function prepare_record(). sql/rpl_utility.cc: Make tabe_def::calc_field_size() a const method. sql/rpl_utility.h: Make table_def::calc_field_size() a const method. Move auto_afree_ptr template here so that it can be re-used (currently in log_event.cc and log_event_old.cc). Similar with DBUG_PRINT_BITSET macro. mysql-test/extra/rpl_tests/rpl_ndb_2multi_basic.test: Modification of rpl_ndb_2multi_eng test.

The change was done because the previous code used to call send_ok() twice, which led to an assertion failure when asserts against it were added by this patch. mysql-test/r/grant.result: Fix the patch for Bug 16470, now FLUSH PRIVILEGES produces an error if mysql.procs_priv is missing. This fixes the assert that send_ok() must not called after send_error() (the original patch for Bug 16470 was prone to this). mysql-test/suite/rpl/r/rpl_row_tabledefs_2myisam.result: Produce a more detailed error message. mysql-test/suite/rpl/r/rpl_row_tabledefs_3innodb.result: Produce a more detailed error message. mysql-test/t/grant.test: Update the test, now FLUSH PRIVILEGES returns an error if mysql.procs_priv is missing. server-tools/instance-manager/mysql_connection.cc: Rename net.last_errno to net.client_last_errno. sql/ha_ndbcluster_binlog.cc: Add asserts. Use getters to access statement status information. Add a comment why run_query() is broken. Reset the diagnostics area in the end of run_query() to fulfill the invariant that the diagnostics_area is never assigned twice per statement (see the comment in the code when this can happen). We still do not clear thd->is_fatal_error and thd->is_slave_error, which may lead to bugs, I consider the whole affair as something to be dealt with separately. sql/ha_partition.cc: fatal_error() doesn't set an error by itself. Perhaps we should remove this method altogether and instead add a flag to my_error to set thd->is_fatal_error property. Meanwhile, this change is a part of inspection made to the entire source code with the goal to ensure that fatal_error() is always accompanied by my_error(). sql/item_func.cc: There is no net.last_error anymore. Remove the obsolete assignment. sql/log_event.cc: Use getters to access statement error status information. sql/log_event_old.cc: Use getters to access statement error status information. sql/mysqld.cc: Previously, if a continue handler for an error was found, my_message_sql() would not set an error in THD. Since the current statement must be aborted in any case, find_handler() had a hack to assign thd->net.report_error to 1. Remove this hack. Set an error in my_message_sql() even if the continue handler is found. The error will be cleared anyway when the handler is executed. This is one action among many in this patch to ensure the invariant that whenever thd->is_error() is TRUE, we have a message in thd->main_da.message(). sql/net_serv.cc: Use a full-blown my_error() in net_serv.cc to report an error, instead of just setting net->last_errno. This ensures the invariant that whenever thd->is_error() returns TRUE, we have a message in thd->main_da.message(). Remove initialization of removed NET members. sql/opt_range.cc: Use my_error() instead of just raising thd->net.report_error. This ensures the invariant that whenever thd->is_error() returns TRUE, there is a message in thd->main_da.message(). sql/opt_sum.cc: Move invocation of fatal_error() right next to the place where we set the error message. That makes it easier to track that whenever fatal_error() is called, there is a message in THD. sql/protocol.cc: Rename send_ok() and send_eof() to net_send_ok() and net_send_eof() respectively. These functions write directly to the network and are not for use anywhere outside the client/server protocol code. Remove the code that was responsible for cases when either there is no error code, or no error message, or both. Instead the calling code ensures that they are always present. Asserts are added to enforce the invariant. Instead of a direct access to thd->server_status and thd->total_warn_count use function parameters, since these from now on don't always come directly from THD. Introduce net_end_statement(), the single-entry-point replacement API for send_ok(), send_eof() and net_send_error(). Implement Protocol::end_partial_result_set to use in select_send::abort() when there is a continue handler. sql/protocol.h: Update declarations. sql/repl_failsafe.cc: Use getters to access statement status information in THD. Rename net.last_error to net.client_last_error. sql/rpl_record.cc: Set an error message in prepare_record() if there is no default value for the field -- later we do print this message to the client. sql/rpl_rli.cc: Use getters to access statement status information in THD. sql/slave.cc: In create_table_from_dump() (a common function that is used in LOAD MASTER TABLE SQL statement and COM_LOAD_MASTER_DATA), instead of hacks with no_send_ok, clear the diagnostics area when mysql_rm_table() succeeded. Update has_temporary_error() to work correctly when no error is set. This is the case when Incident_log_event is executed: it always returns an error but does not set an error message. Use getters to access error status information. sql/sp_head.cc: Instead of hacks with no_send_error, work through the diagnostics area interface to suppress sending of OK/ERROR packets to the client. Move query_cache_end_of_result before log_slow_statement(), similarly to how it's done in dispatch_command(). sql/sp_rcontext.cc: Remove hacks with assignment of thd->net.report_error, they are not necessary any more (see the changes in mysqld.cc). sql/sql_acl.cc: Use getters to access error status information in THD. sql/sql_base.cc: Access thd->main_da.sql_errno() only if there is an error. This fixes a bug when auto-discovery, that was effectively disabled under pre-locking. sql/sql_binlog.cc: Remove hacks with no_send_ok/no_send_error, they are not necessary anymore: the caller is responsible for network communication. sql/sql_cache.cc: Disable sending of OK/ERROR/EOF packet in the end of dispatch_command if the response has been served from the query cache. This raises the question whether we should store EOF packet in the query cache at all, or generate it anew for each statement (we should generate it anew), but this is to be addressed separately. sql/sql_class.cc: Implement class Diagnostics_area. Please see comments in sql_class.h for details. Fix a subtle coding mistake in select_send::send_data: when on slave, an error in Item::send() was ignored. The problem became visible due to asserts that the diagnostics area is never double assigned. Remove initialization of removed NET members. In select_send::abort() do not call select_send::send_eof(). This is not inheritance-safe. Even if a stored procedure continue handler is found, the current statement is aborted, not succeeded. Instead introduce a Protocol API to send the required response, Protocol::end_partial_result_set(). This simplifies implementation of select_send::send_eof(). No need to add more asserts that there is no error, there is an assert inside Diagnostics_area::set_ok_status() already. Leave no trace of no_send_* in the code. sql/sql_class.h: Declare class Diagnostics_area. Remove the hack with no_send_ok from Substatement_state. Provide inline implementations of send_ok/send_eof. Add commetns. sql/sql_connect.cc: Remove hacks with no_send_error. Since now an error in THD is always set if net->error, it's not necessary to check both net->error and thd->is_error() in the do_command loop. Use thd->main_da.message() instead of net->last_errno. Remove the hack with is_slave_error in sys_init_connect. Since now we do not reset the diagnostics area in net_send_error (it's reset at the beginning of the next statement), we can access it safely even after execute_init_command. sql/sql_db.cc: Update the code to satisfy the invariant that the diagnostics area is never assigned twice. Incidentally, this fixes Bug 29958 "Weird message on DROP DATABASE if mysql.proc does not exist". sql/sql_delete.cc: Change multi-delete to abort in abort(), as per select_send protocol. Fixes the merge error with the test for Bug 29136 sql/sql_derived.cc: Use getters to access error information. sql/sql_insert.cc: Use getters to access error information. sql-common/client.c: Rename last_error to client_last_error, last_errno to client_last_errno. sql/sql_parse.cc: Remove hacks with no_send_error. Deploy net_end_statement(). The story of COM_SHUTDOWN is interesting. Long story short, the server would become on its death's door, and only no_send_ok/no_send_error assigned by send_ok()/net_send_error() would hide its babbling from the client. First of all, COM_QUIT does not require a response. So, the comment saying "Let's send a response to possible COM_QUIT" is not only groundless (even mysqladmin shutdown/mysql_shutdown() doesn't send COM_QUIT after COM_SHUTDOWN), it's plainly incorrect. Secondly, besides this additional 'OK' packet to respond to a hypothetical COM_QUIT, there was the following code in dispatch_command(): if (thd->killed) thd->send_kill_message(); if (thd->is_error() net_send_error(thd); This worked out really funny for the thread through which COM_SHUTDOWN was delivered: we would get COM_SHUTDOWN, say okay, say okay again, kill everybody, get the kill signal ourselves, and then attempt to say "Server shutdown in progress" to the client that is very likely long gone. This all became visible when asserts were added that the Diagnostics_area is not assigned twice. Move query_cache_end_of_result() to the end of dispatch_command(), since net_send_eof() has been moved there. This is safe, query_cache_end_of_result() is a no-op if there is no started query in the cache. Consistently use select_send interface to call abort() or send_eof() depending on the operation result. Remove thd->fatal_error() from reset_master(), it was a no-op. in hacks with no_send_error woudl save us from complete breakage of the client/server protocol. Consistently use select_send::abort() whenever there is an error, and select_send::send_eof() in case of success. The issue became visible due to added asserts. sql/sql_partition.cc: Always set an error in THD whenever there is a call to fatal_error(). sql/sql_prepare.cc: Deploy class Diagnostics_area. Remove the unnecessary juggling with the protocol in Select_fetch_protocol_binary::send_eof(). EOF packet format is protocol-independent. sql/sql_select.cc: Call fatal_error() directly in opt_sum_query. Call my_error() whenever we call thd->fatal_error(). sql/sql_servers.cc: Use getters to access error information in THD. sql/sql_show.cc: Use getters to access error information in THD. Add comments. Call my_error() whenever we call fatal_error(). sql/sql_table.cc: Replace hacks with no_send_ok with the interface of the diagnostics area. Clear the error if ENOENT error in ha_delete_table(). sql/sql_update.cc: Introduce multi_update::abort(), which is the proper way to abort a multi-update. This fixes the merge conflict between this patch and the patch for Bug 29136. sql/table.cc: Use a getter to access error information in THD. sql/tztime.cc: Use a getter to access error information in THD.

BUG#21842 (Cluster fails to replicate to innodb or myisam with err 134 using TPC-B): Problem: A RBR event can contain incomplete row data (only key value and fields which have been changed). In that case, when the row is unpacked into record and written to a table, the missing fields get incorrect NULL values leading to master-slave inconsistency. Solution: Use values found in slave's table for columns which are not given in the rows event. The code for writing a single row uses the following algorithm: 1. unpack row_data into table->record[0], 2. try to insert record, 3. if duplicate record found, fetch it into table->record[0], 4. unpack row_data into table->record[0], 5. write table->record[0] into the table. Where row_data is the row as stored in the data area of a rows event. Thus: a) unpacking of row_data happens at the time when row is written into a table, b) when unpacking (in step 4), only columns present in row_data are overwritten - all other columns remain as they were found in the table. Since all data needed for the above algorithm is stored inside Rows_log_event class, functions which locate and write rows are turned into methods of that class. replace_record() -> Rows_log_event::write_row() find_and_fetch_row() -> Rows_log_event::find_row() Both methods take row data from event's data buffer - the row being processed is pointed by m_curr_row. They unpack the data as needed into table's record buffers record[0] or record[1]. When row is unpacked, m_curr_row_end is set to point at next row in the data buffer. Other changes introduced in this changeset: - Change signature of unpack_row(): don't report errors and don't setup table's rw_set here. Errors can happen only when setting default values in prepare_record() function and are detected there. - In Rows_log_event and derived classes, don't pass arguments to the execution primitives (do_...() member functions) but use class members instead. - Move old row handling code into log_event_old.cc to be used by *_rows_log_event_old classes. Also, a new test rpl_ndb_2other is added which tests basic replication from master using ndb tables to slave storing the same tables using (possibly) different engine (myisam,innodb). Test is based on existing tests rpl_ndb_2myisam and rpl_ndb_2innodb. However, these tests doesn't work for various reasons and currently are disabled (see BUG#19227). The new test differs from the ones it is based on as follows: 1. Single test tests replication with different storage engines on slave (myisam, innodb, ndb). 2. Include file extra/rpl_tests/rpl_ndb_2multi_eng.test containing original tests is replaced by extra/rpl_tests/rpl_ndb_2multi_basic.test which doesn't contain tests using partitioned tables as these don't work currently. Instead, it tests replication to a slave which has more or less columns than master. 3. Include file include/rpl_multi_engine3.inc is replaced with include/rpl_multi_engine2.inc. The later differs by performing slightly different operations (updating more than one row in the table) and clearing table with "TRUNCATE TABLE" statement instead of "DELETE FROM" as replication of "DELETE" doesn't work well in this setting. 4. Slave must use option --log-slave-updates=0 as otherwise execution of replication events generated by ndb fails if table uses a different storage engine on slave (see BUG#29569). sql/log_event.cc: - Initialization of new Rows_log_event members. - Fixing some typos in documentation. In Rows_log_event::do_apply_event: - Set COMPLETE_ROWS_F flag (when master and slave have the same number of columns and all colums are present in the row) - Move initialization of tables write/read sets here, outside the rows processing loop (and out of unpack_row() function). - Remove calls to do_prepare_row() - no longer needed. - Add code managing m_curr_row and m_curr_row_end pointers. - Change signatures of row processing methods of Rows_log_event and it descendants - now most arguments are taken from class members. - Remove do_prepare_row() methods which are no longer used. - The auto_afree_ptr template is moved to rpl_utility.h (so that it can be used in log_event_old.cc). - Removed copy_extra_fields() function - no longer used. In Rows_log_event::write_row (former replace_record): - The old code is moved to log_event_old.cc. - Use prepare_record() and non-destructive unpack_current_row() to fill record with data. - In case a record being inserted already exists on slave and row data is incomplete use the record found and non-destructive unpack_current_row() to combine new column values with existing ones. - More debug info added. In Rows_log_event::find_row (former find_and_fetch_row function): - The old code is moved to log_event_old.cc. - Unpacking of the row is moved here. - In case of search using PK, the key data is prepared here. - More debug info added. - Remove initialization of Rows_log_event::m_after_image buffer which is no longer used. - Use new row unpacking methods in Update_rows_log_event::do_exec_row() to create before and after image. Note: all existing code used by Rows_log_event::do_apply_event() has been moved to log_event_old.cc to be used by *_rows_log_event_old classes. sql/log_event.h: - Add new COMPLETE_ROWS_F flag in Rows_log_event. - Add Rows_log_event members describing the row being processed. - Add a pointer to key buffer which is used in derived classes. - Add new methods: find__row(), write_row() and unpack_current_row(). - Change signatures of do_...() methods (replace method arguments by class members). - Remove do_prepare_row() method which is no longer used. - Update method documentation. - Add Old_rows_log_event class, which contains the old row processing code, as a friend of Rows_log_event so that it can access all members of an event instance. sql/log_event_old.cc: Move here old implementation of Rows_log_event::do_apply_event() and helper methods. sql/log_event_old.h: - Define new class Old_rows_log_event encapsulating old version of Rows_log_event::do_apply_event() and the helper methods. - Add the Old_rows_log_event class as a base for *_old versions of RBR event classes, ensure that the old version of do_apply_event() is called. - For *_old classes, declare the helper methods used in the old version of do_apply_event(). sql/rpl_record.cc: - Make unpack_row non-destructive for columns not present in the row. - Don't fill read/write set here as it is done outside these functions. - Move initialization of a record with default values to a separate function prepare_record(). sql/rpl_record.h: - Change signature of unpack_row(). - Declare function prepare_record(). sql/rpl_utility.cc: Make tabe_def::calc_field_size() a const method. sql/rpl_utility.h: Make table_def::calc_field_size() a const method. Move auto_afree_ptr template here so that it can be re-used (currently in log_event.cc and log_event_old.cc). Similar with DBUG_PRINT_BITSET macro. mysql-test/extra/rpl_tests/rpl_ndb_2multi_basic.test: Modification of rpl_ndb_2multi_eng test. Tests with partitioned tables are removed and a setup with slave having different number of columns than master is added. mysql-test/include/rpl_multi_engine2.inc: Modification of rpl_multi_engine3.inc which operates on more rows and replaces "DELETE FROM t1" with "TRUNCATE TABLE t1" as the first form doesn't replicate in NDB -> non-NDB setting (BUG#28538). mysql-test/suite/rpl_ndb/r/rpl_ndb_2other.result: Results of the test. mysql-test/suite/rpl_ndb/t/rpl_ndb_2other-slave.opt: Test options. --log-slave-updates=0 is compulsory as otherwise non-NDB slave applying row events from NDB master will fail when trying to log them. mysql-test/suite/rpl_ndb/t/rpl_ndb_2other.test: Test replication of NDB table to slave using other engine. The main test is in extra/rpl_tests/rpl_ndb_2multi_basic.test. It is included here several times with different settings of default storage engine on slave.

The later differs by performing slightly different operations (updating more than one row in the table) and clearing table with "TRUNCATE TABLE" statement instead of "DELETE FROM" as replication of "DELETE" doesn't work well in this setting. 4. Slave must use option --log-slave-updates=0 as otherwise execution of replication events generated by ndb fails if table uses a different storage engine on slave (see BUG#29569). sql/log_event.cc: - Initialization of new Rows_log_event members. - Fixing some typos in documentation. In Rows_log_event::do_apply_event: - Set COMPLETE_ROWS_F flag (when master and slave have the same number of columns and all colums are present in the row) - Move initialization of tables write/read sets here, outside the rows processing loop (and out of unpack_row() function). - Remove calls to do_prepare_row() - no longer needed. - Add code managing m_curr_row and m_curr_row_end pointers. - Change signatures of row processing methods of Rows_log_event and it descendants - now most arguments are taken from class members. - Remove do_prepare_row() methods which are no longer used. - The auto_afree_ptr template is moved to rpl_utility.h (so that it can be used in log_event_old.cc). - Removed copy_extra_fields() function - no longer used. In Rows_log_event::write_row (former replace_record): - The old code is moved to log_event_old.cc. - Use prepare_record() and non-destructive unpack_current_row() to fill record with data. - In case a record being inserted already exists on slave and row data is incomplete use the record found and non-destructive unpack_current_row() to combine new column values with existing ones. - More debug info added. In Rows_log_event::find_row (former find_and_fetch_row function): - The old code is moved to log_event_old.cc. - Unpacking of the row is moved here. - In case of search using PK, the key data is prepared here. - More debug info added. - Remove initialization of Rows_log_event::m_after_image buffer which is no longer used. - Use new row unpacking methods in Update_rows_log_event::do_exec_row() to create before and after image. Note: all existing code used by Rows_log_event::do_apply_event() has been moved to log_event_old.cc to be used by *_rows_log_event_old classes. sql/log_event.h: - Add new COMPLETE_ROWS_F flag in Rows_log_event. - Add Rows_log_event members describing the row being processed. - Add a pointer to key buffer which is used in derived classes. - Add new methods: find__row(), write_row() and unpack_current_row(). - Change signatures of do_...() methods (replace method arguments by class members). - Remove do_prepare_row() method which is no longer used. - Update method documentation. - Add Old_rows_log_event class, which contains the old row processing code, as a friend of Rows_log_event so that it can access all members of an event instance. sql/log_event_old.cc: Move here old implementation of Rows_log_event::do_apply_event() and helper methods. sql/log_event_old.h: - Define new class Old_rows_log_event encapsulating old version of Rows_log_event::do_apply_event() and the helper methods. - Add the Old_rows_log_event class as a base for *_old versions of RBR event classes, ensure that the old version of do_apply_event() is called. - For *_old classes, declare the helper methods used in the old version of do_apply_event(). sql/rpl_record.cc: - Make unpack_row non-destructive for columns not present in the row. - Don't fill read/write set here as it is done outside these functions. - Move initialization of a record with default values to a separate function prepare_record(). sql/rpl_record.h: - Change signature of unpack_row(). - Declare function prepare_record(). sql/rpl_utility.cc: Make tabe_def::calc_field_size() a const method. sql/rpl_utility.h: Make table_def::calc_field_size() a const method.

BUG#31581: 5.1-telco-6.1 -> 5.1.22. Slave crashes during starting This patch has two purposes: (1) To refactor the code so that {Write|Update|Delete}_rows_log_event_old does not use code from {Write|Update|Delete}_rows_log_event. Before refactoring there was the following problem: whenever we modifed the code for new events, it affected the old events. This is bad, as it makes maintainance difficult. After refactoring, we can safely edit the new code without affecting old events. So, if we for instance modify the binary format of new events, we no longer need to worry about how the new code reads old events. (2) To fix BUG#31581. These two objectives are reached by the following changes: - Merged Rows_log_event into Old_rows_log_event and {Write|Update|Delete}_rows_log_event into {Write|Update|Delete}_rows_log_event_old. - Fixed the bug by replacing {WRITE|UPDATE|DELETE}_ROWS_EVENT by PRE_GA_{WRITE|UPDATE|DELETE}_ROWS_EVENT. - Added comments to log_event_old.h (This patch is identical to the previously committed patch which was a collapse of three changesets, except that it adds assert(0) to constructors for old types of row log events that should never be called.) sql/log_event_old.cc: Merged Rows_log_event into Old_rows_log_event and {Write|Update|Delete}_rows_log_event into {Write|Update|Delete}_rows_log_event_old. Also fixed the bug by replacing {WRITE|UPDATE|DELETE}_ROWS_EVENT by PRE_GA_{WRITE|UPDATE|DELETE}_ROWS_EVENT. sql/log_event_old.h: Merged Rows_log_event into Old_rows_log_event and {Write|Update|Delete}_rows_log_event into {Write|Update|Delete}_rows_log_event_old. Also added comment explaining what the file contains and what the classes do.

BUG#21842 (Cluster fails to replicate to innodb or myisam with err 134 using TPC-B): Problem: A RBR event can contain incomplete row data (only key value and fields which have been changed). In that case, when the row is unpacked into record and written to a table, the missing fields get incorrect NULL values leading to master-slave inconsistency. Solution: Use values found in slave's table for columns which are not given in the rows event. The code for writing a single row uses the following algorithm: 1. unpack row_data into table->record[0], 2. try to insert record, 3. if duplicate record found, fetch it into table->record[0], 4. unpack row_data into table->record[0], 5. write table->record[0] into the table. Where row_data is the row as stored in the data area of a rows event. Thus: a) unpacking of row_data happens at the time when row is written into a table, b) when unpacking (in step 4), only columns present in row_data are overwritten - all other columns remain as they were found in the table. Since all data needed for the above algorithm is stored inside Rows_log_event class, functions which locate and write rows are turned into methods of that class. replace_record() -> Rows_log_event::write_row() find_and_fetch_row() -> Rows_log_event::find_row() Both methods take row data from event's data buffer - the row being processed is pointed by m_curr_row. They unpack the data as needed into table's record buffers record[0] or record[1]. When row is unpacked, m_curr_row_end is set to point at next row in the data buffer. Other changes introduced in this changeset: - Change signature of unpack_row(): don't report errors and don't setup table's rw_set here. Errors can happen only when setting default values in prepare_record() function and are detected there. - In Rows_log_event and derived classes, don't pass arguments to the execution primitives (do_...() member functions) but use class members instead. - Move old row handling code into log_event_old.cc to be used by *_rows_log_event_old classes. Also, a new test rpl_ndb_2other is added which tests basic replication from master using ndb tables to slave storing the same tables using (possibly) different engine (myisam,innodb). Test is based on existing tests rpl_ndb_2myisam and rpl_ndb_2innodb. However, these tests doesn't work for various reasons and currently are disabled (see BUG#19227). The new test differs from the ones it is based on as follows: 1. Single test tests replication with different storage engines on slave (myisam, innodb, ndb). 2. Include file extra/rpl_tests/rpl_ndb_2multi_eng.test containing original tests is replaced by extra/rpl_tests/rpl_ndb_2multi_basic.test which doesn't contain tests using partitioned tables as these don't work currently.

Bug#12713 "Error in a stored function called from a SELECT doesn't cause ROLLBACK of statement", part 1. Review fixes. Do not send OK/EOF packets to the client until we reached the end of the current statement. This is a consolidation, to keep the functionality that is shared by all SQL statements in one place in the server. Currently this functionality includes: - close_thread_tables() - log_slow_statement(). After this patch and the subsequent patch for Bug#12713, it shall also include: - ha_autocommit_or_rollback() - net_end_statement() - query_cache_end_of_result(). In future it may also include: - mysql_reset_thd_for_next_command(). include/mysql_com.h: Rename now unused members of NET: no_send_ok, no_send_error, report_error. These were server-specific variables related to the client/server protocol. They have been made obsolete by this patch. Previously the same members of NET were used to store the error message both on the client and on the server. The error message was stored in net.last_error (client: mysql->net.last_error, server: thd->net.last_error). The error code was stored in net.last_errno (client: mysql->net.last_errno, server: thd->net.last_errno). The server error code and message are now stored elsewhere (in the Diagnostics_area), thus NET members are no longer used by the server. Rename last_error to client_last_error, last_errno to client_last_errno to avoid potential bugs introduced by merges. include/mysql_h.ic: Update the ABI file to reflect a rename. Renames do not break the binary compatibility. libmysql/libmysql.c: Rename last_error to client_last_error, last_errno to client_last_errno. This is necessary to ensure no unnoticed bugs introduced by merged changesets. Remove net.report_error, net.no_send_ok, net.no_send_error. libmysql/manager.c: Rename net.last_errno to net.client_last_errno. libmysqld/lib_sql.cc: Rename net.last_errno to net.client_last_errno. Update the embedded implementation of the client-server protocol to reflect the refactoring of protocol.cc. libmysqld/libmysqld.c: Rename net.last_errno to net.client_last_errno. mysql-test/r/events.result: Update to reflect the change in mysql_rm_db(). Now we drop stored routines and events for a given database name only if there is a directory for this database name. ha_drop_database() and query_cache_invalidate() are called likewise. Previously we would attempt to drop routines/events even if database directory was not found (it worked, since routines and events are stored in tables). This fixes Bug 29958 "Weird message on DROP DATABASE if mysql.proc does not exist". The change was done because the previous code used to call send_ok() twice, which led to an assertion failure when asserts against it were added by this patch. mysql-test/r/grant.result: Fix the patch for Bug 16470, now FLUSH PRIVILEGES produces an error if mysql.procs_priv is missing. This fixes the assert that send_ok() must not called after send_error() (the original patch for Bug 16470 was prone to this). mysql-test/suite/rpl/r/rpl_row_tabledefs_2myisam.result: Produce a more detailed error message. mysql-test/suite/rpl/r/rpl_row_tabledefs_3innodb.result: Produce a more detailed error message. mysql-test/t/grant.test: Update the test, now FLUSH PRIVILEGES returns an error if mysql.procs_priv is missing. server-tools/instance-manager/mysql_connection.cc: Rename net.last_errno to net.client_last_errno. sql/ha_ndbcluster_binlog.cc: Add asserts. Use getters to access statement status information. Add a comment why run_query() is broken. Reset the diagnostics area in the end of run_query() to fulfill the invariant that the diagnostics_area is never assigned twice per statement (see the comment in the code when this can happen). We still do not clear thd->is_fatal_error and thd->is_slave_error, which may lead to bugs, I consider the whole affair as something to be dealt with separately. sql/ha_partition.cc: fatal_error() doesn't set an error by itself. Perhaps we should remove this method altogether and instead add a flag to my_error to set thd->is_fatal_error property. Meanwhile, this change is a part of inspection made to the entire source code with the goal to ensure that fatal_error() is always accompanied by my_error(). sql/item_func.cc: There is no net.last_error anymore. Remove the obsolete assignment. sql/log_event.cc: Use getters to access statement error status information. sql/log_event_old.cc: Use getters to access statement error status information. sql/mysqld.cc: Previously, if a continue handler for an error was found, my_message_sql() would not set an error in THD. Since the current statement must be aborted in any case, find_handler() had a hack to assign thd->net.report_error to 1. Remove this hack. Set an error in my_message_sql() even if the continue handler is found. The error will be cleared anyway when the handler is executed. This is one action among many in this patch to ensure the invariant that whenever thd->is_error() is TRUE, we have a message in thd->main_da.message(). sql/net_serv.cc: Use a full-blown my_error() in net_serv.cc to report an error, instead of just setting net->last_errno. This ensures the invariant that whenever thd->is_error() returns TRUE, we have a message in thd->main_da.message(). Remove initialization of removed NET members. sql/opt_range.cc: Use my_error() instead of just raising thd->net.report_error. This ensures the invariant that whenever thd->is_error() returns TRUE, there is a message in thd->main_da.message(). sql/opt_sum.cc: Move invocation of fatal_error() right next to the place where we set the error message. That makes it easier to track that whenever fatal_error() is called, there is a message in THD. sql/protocol.cc: Rename send_ok() and send_eof() to net_send_ok() and net_send_eof() respectively. These functions write directly to the network and are not for use anywhere outside the client/server protocol code. Remove the code that was responsible for cases when either there is no error code, or no error message, or both. Instead the calling code ensures that they are always present. Asserts are added to enforce the invariant. Instead of a direct access to thd->server_status and thd->total_warn_count use function parameters, since these from now on don't always come directly from THD. Introduce net_end_statement(), the single-entry-point replacement API for send_ok(), send_eof() and net_send_error(). Implement Protocol::end_partial_result_set to use in select_send::abort() when there is a continue handler. sql/protocol.h: Update declarations. sql/repl_failsafe.cc: Use getters to access statement status information in THD. Rename net.last_error to net.client_last_error. sql/rpl_record.cc: Set an error message in prepare_record() if there is no default value for the field -- later we do print this message to the client. sql/rpl_rli.cc: Use getters to access statement status information in THD. sql/slave.cc: In create_table_from_dump() (a common function that is used in LOAD MASTER TABLE SQL statement and COM_LOAD_MASTER_DATA), instead of hacks with no_send_ok, clear the diagnostics area when mysql_rm_table() succeeded. Update has_temporary_error() to work correctly when no error is set. This is the case when Incident_log_event is executed: it always returns an error but does not set an error message. Use getters to access error status information. sql/sp_head.cc: Instead of hacks with no_send_error, work through the diagnostics area interface to suppress sending of OK/ERROR packets to the client. Move query_cache_end_of_result before log_slow_statement(), similarly to how it's done in dispatch_command(). sql/sp_rcontext.cc: Remove hacks with assignment of thd->net.report_error, they are not necessary any more (see the changes in mysqld.cc). sql/sql_acl.cc: Use getters to access error status information in THD. sql/sql_base.cc: Access thd->main_da.sql_errno() only if there is an error. This fixes a bug when auto-discovery, that was effectively disabled under pre-locking. sql/sql_binlog.cc: Remove hacks with no_send_ok/no_send_error, they are not necessary anymore: the caller is responsible for network communication. sql/sql_cache.cc: Disable sending of OK/ERROR/EOF packet in the end of dispatch_command if the response has been served from the query cache. This raises the question whether we should store EOF packet in the query cache at all, or generate it anew for each statement (we should generate it anew), but this is to be addressed separately. sql/sql_class.cc: Implement class Diagnostics_area. Please see comments in sql_class.h for details. Fix a subtle coding mistake in select_send::send_data: when on slave, an error in Item::send() was ignored. The problem became visible due to asserts that the diagnostics area is never double assigned. Remove initialization of removed NET members. In select_send::abort() do not call select_send::send_eof(). This is not inheritance-safe. Even if a stored procedure continue handler is found, the current statement is aborted, not succeeded. Instead introduce a Protocol API to send the required response, Protocol::end_partial_result_set(). This simplifies implementation of select_send::send_eof(). No need to add more asserts that there is no error, there is an assert inside Diagnostics_area::set_ok_status() already. Leave no trace of no_send_* in the code. sql/sql_class.h: Declare class Diagnostics_area. Remove the hack with no_send_ok from Substatement_state. Provide inline implementations of send_ok/send_eof. Add commetns. sql/sql_connect.cc: Remove hacks with no_send_error. Since now an error in THD is always set if net->error, it's not necessary to check both net->error and thd->is_error() in the do_command loop. Use thd->main_da.message() instead of net->last_errno. Remove the hack with is_slave_error in sys_init_connect. Since now we do not reset the diagnostics area in net_send_error (it's reset at the beginning of the next statement), we can access it safely even after execute_init_command. sql/sql_db.cc: Update the code to satisfy the invariant that the diagnostics area is never assigned twice. Incidentally, this fixes Bug 29958 "Weird message on DROP DATABASE if mysql.proc does not exist". sql/sql_delete.cc: Change multi-delete to abort in abort(), as per select_send protocol. Fixes the merge error with the test for Bug 29136 sql/sql_derived.cc: Use getters to access error information. sql/sql_insert.cc: Use getters to access error information. sql-common/client.c: Rename last_error to client_last_error, last_errno to client_last_errno. sql/sql_parse.cc: Remove hacks with no_send_error. Deploy net_end_statement(). The story of COM_SHUTDOWN is interesting. Long story short, the server would become on its death's door, and only no_send_ok/no_send_error assigned by send_ok()/net_send_error() would hide its babbling from the client. First of all, COM_QUIT does not require a response. So, the comment saying "Let's send a response to possible COM_QUIT" is not only groundless (even mysqladmin shutdown/mysql_shutdown() doesn't send COM_QUIT after COM_SHUTDOWN), it's plainly incorrect. Secondly, besides this additional 'OK' packet to respond to a hypothetical COM_QUIT, there was the following code in dispatch_command(): if (thd->killed) thd->send_kill_message(); if (thd->is_error() net_send_error(thd); This worked out really funny for the thread through which COM_SHUTDOWN was delivered: we would get COM_SHUTDOWN, say okay, say okay again, kill everybody, get the kill signal ourselves, and then attempt to say "Server shutdown in progress" to the client that is very likely long gone. This all became visible when asserts were added that the Diagnostics_area is not assigned twice. Move query_cache_end_of_result() to the end of dispatch_command(), since net_send_eof() has been moved there. This is safe, query_cache_end_of_result() is a no-op if there is no started query in the cache. Consistently use select_send interface to call abort() or send_eof() depending on the operation result. Remove thd->fatal_error() from reset_master(), it was a no-op. in hacks with no_send_error woudl save us from complete breakage of the client/server protocol. Consistently use select_send::abort() whenever there is an error, and select_send::send_eof() in case of success. The issue became visible due to added asserts. sql/sql_partition.cc: Always set an error in THD whenever there is a call to fatal_error(). sql/sql_prepare.cc: Deploy class Diagnostics_area. Remove the unnecessary juggling with the protocol in Select_fetch_protocol_binary::send_eof(). EOF packet format is protocol-independent. sql/sql_select.cc: Call fatal_error() directly in opt_sum_query. Call my_error() whenever we call thd->fatal_error(). sql/sql_servers.cc: Use getters to access error information in THD. sql/sql_show.cc: Use getters to access error information in THD. Add comments. Call my_error() whenever we call fatal_error(). sql/sql_table.cc: Replace hacks with no_send_ok with the interface of the diagnostics area. Clear the error if ENOENT error in ha_delete_table(). sql/sql_update.cc: Introduce multi_update::abort(), which is the proper way to abort a multi-update. This fixes the merge conflict between this patch and the patch for Bug 29136. sql/table.cc: Use a getter to access error information in THD. sql/tztime.cc: Use a getter to access error information in THD.

Thus: a) unpacking of row_data happens at the time when row is written into a table, b) when unpacking (in step 4), only columns present in row_data are overwritten - all other columns remain as they were found in the table. Since all data needed for the above algorithm is stored inside Rows_log_event class, functions which locate and write rows are turned into methods of that class. replace_record() -> Rows_log_event::write_row() find_and_fetch_row() -> Rows_log_event::find_row() Both methods take row data from event's data buffer - the row being processed is pointed by m_curr_row. They unpack the data as needed into table's record buffers record[0] or record[1]. When row is unpacked, m_curr_row_end is set to point at next row in the data buffer. Other changes introduced in this changeset: - Change signature of unpack_row(): don't report errors and don't setup table's rw_set here. Errors can happen only when setting default values in prepare_record() function and are detected there. - In Rows_log_event and derived classes, don't pass arguments to the execution primitives (do_...() member functions) but use class members instead. - Move old row handling code into log_event_old.cc to be used by *_rows_log_event_old classes. Also, a new test rpl_ndb_2other is added which tests basic replication from master using ndb tables to slave storing the same tables using (possibly) different engine (myisam,innodb). Test is based on existing tests rpl_ndb_2myisam and rpl_ndb_2innodb. However, these tests doesn't work for various reasons and currently are disabled (see BUG#19227). The new test differs from the ones it is based on as follows: 1. Single test tests replication with different storage engines on slave (myisam, innodb, ndb). 2. Include file extra/rpl_tests/rpl_ndb_2multi_eng.test containing original tests is replaced by extra/rpl_tests/rpl_ndb_2multi_basic.test which doesn't contain tests using partitioned tables as these don't work currently. Instead, it tests replication to a slave which has more or less columns than master. 3. Include file include/rpl_multi_engine3.inc is replaced with include/rpl_multi_engine2.inc. The later differs by performing slightly different operations (updating more than one row in the table) and clearing table with "TRUNCATE TABLE" statement instead of "DELETE FROM" as replication of "DELETE" doesn't work well in this setting. 4. Slave must use option --log-slave-updates=0 as otherwise execution of replication events generated by ndb fails if table uses a different storage engine on slave (see BUG#29569). sql/log_event.cc: - Initialization of new Rows_log_event members. - Fixing some typos in documentation. In Rows_log_event::do_apply_event: - Set COMPLETE_ROWS_F flag (when master and slave have the same number of columns and all colums are present in the row) - Move initialization of tables write/read sets here, outside the rows processing loop (and out of unpack_row() function). - Remove calls to do_prepare_row() - no longer needed. - Add code managing m_curr_row and m_curr_row_end pointers. - Change signatures of row processing methods of Rows_log_event and it descendants - now most arguments are taken from class members. - Remove do_prepare_row() methods which are no longer used. - The auto_afree_ptr template is moved to rpl_utility.h (so that it can be used in log_event_old.cc). - Removed copy_extra_fields() function - no longer used. In Rows_log_event::write_row (former replace_record): - The old code is moved to log_event_old.cc. - Use prepare_record() and non-destructive unpack_current_row() to fill record with data. - In case a record being inserted already exists on slave and row data is incomplete use the record found and non-destructive unpack_current_row() to combine new column values with existing ones. - More debug info added. In Rows_log_event::find_row (former find_and_fetch_row function): - The old code is moved to log_event_old.cc. - Unpacking of the row is moved here. - In case of search using PK, the key data is prepared here. - More debug info added. - Remove initialization of Rows_log_event::m_after_image buffer which is no longer used. - Use new row unpacking methods in Update_rows_log_event::do_exec_row() to create before and after image. Note: all existing code used by Rows_log_event::do_apply_event() has been moved to log_event_old.cc to be used by *_rows_log_event_old classes. sql/log_event.h: - Add new COMPLETE_ROWS_F flag in Rows_log_event. - Add Rows_log_event members describing the row being processed. - Add a pointer to key buffer which is used in derived classes. - Add new methods: find__row(), write_row() and unpack_current_row(). - Change signatures of do_...() methods (replace method arguments by class members). - Remove do_prepare_row() method which is no longer used. - Update method documentation. - Add Old_rows_log_event class, which contains the old row processing code, as a friend of Rows_log_event so that it can access all members of an event instance. sql/log_event_old.cc: Move here old implementation of Rows_log_event::do_apply_event() and helper methods. sql/log_event_old.h: - Define new class Old_rows_log_event encapsulating old version of Rows_log_event::do_apply_event() and the helper methods. - Add the Old_rows_log_event class as a base for *_old versions of RBR event classes, ensure that the old version of do_apply_event() is called. - For *_old classes, declare the helper methods used in the old version of do_apply_event(). sql/rpl_record.cc: - Make unpack_row non-destructive for columns not present in the row. - Don't fill read/write set here as it is done outside these functions. - Move initialization of a record with default values to a separate function prepare_record(). sql/rpl_record.h: - Change signature of unpack_row(). - Declare function prepare_record(). sql/rpl_utility.cc: Make tabe_def::calc_field_size() a const method. sql/rpl_utility.h: Make table_def::calc_field_size() a const method. Move auto_afree_ptr template here so that it can be re-used (currently in log_event.cc and log_event_old.cc). Similar with DBUG_PRINT_BITSET macro. mysql-test/extra/rpl_tests/rpl_ndb_2multi_basic.test: Modification of rpl_ndb_2multi_eng test. Tests with partitioned tables are removed and a setup with slave having different number of columns than master is added. mysql-test/include/rpl_multi_engine2.inc: Modification of rpl_multi_engine3.inc which operates on more rows and replaces "DELETE FROM t1" with "TRUNCATE TABLE t1" as the first form doesn't replicate in NDB -> non-NDB setting (BUG#28538). mysql-test/suite/rpl_ndb/r/rpl_ndb_2other.result: Results of the test. mysql-test/suite/rpl_ndb/t/rpl_ndb_2other-slave.opt: Test options. --log-slave-updates=0 is compulsory as otherwise non-NDB slave applying row events from NDB master will fail when trying to log them. mysql-test/suite/rpl_ndb/t/rpl_ndb_2other.test: Test replication of NDB table to slave using other engine. The main test is in extra/rpl_tests/rpl_ndb_2multi_basic.test. It is included here several times with different settings of default storage engine on slave.

Bug#12713 "Error in a stored function called from a SELECT doesn't cause ROLLBACK of statement", part 1. Review fixes. Do not send OK/EOF packets to the client until we reached the end of the current statement. This is a consolidation, to keep the functionality that is shared by all SQL statements in one place in the server. Currently this functionality includes: - close_thread_tables() - log_slow_statement(). After this patch and the subsequent patch for Bug#12713, it shall also include: - ha_autocommit_or_rollback() - net_end_statement() - query_cache_end_of_result(). In future it may also include: - mysql_reset_thd_for_next_command(). include/mysql_com.h: Rename now unused members of NET: no_send_ok, no_send_error, report_error. These were server-specific variables related to the client/server protocol. They have been made obsolete by this patch. Previously the same members of NET were used to store the error message both on the client and on the server. The error message was stored in net.last_error (client: mysql->net.last_error, server: thd->net.last_error). The error code was stored in net.last_errno (client: mysql->net.last_errno, server: thd->net.last_errno). The server error code and message are now stored elsewhere (in the Diagnostics_area), thus NET members are no longer used by the server. Rename last_error to client_last_error, last_errno to client_last_errno to avoid potential bugs introduced by merges. include/mysql_h.ic: Update the ABI file to reflect a rename. Renames do not break the binary compatibility. libmysql/libmysql.c: Rename last_error to client_last_error, last_errno to client_last_errno. This is necessary to ensure no unnoticed bugs introduced by merged changesets. Remove net.report_error, net.no_send_ok, net.no_send_error. libmysql/manager.c: Rename net.last_errno to net.client_last_errno. libmysqld/lib_sql.cc: Rename net.last_errno to net.client_last_errno. Update the embedded implementation of the client-server protocol to reflect the refactoring of protocol.cc. libmysqld/libmysqld.c: Rename net.last_errno to net.client_last_errno. mysql-test/r/events.result: Update to reflect the change in mysql_rm_db(). Now we drop stored routines and events for a given database name only if there is a directory for this database name. ha_drop_database() and query_cache_invalidate() are called likewise. Previously we would attempt to drop routines/events even if database directory was not found (it worked, since routines and events are stored in tables). This fixes Bug 29958 "Weird message on DROP DATABASE if mysql.proc does not exist". The change was done because the previous code used to call send_ok() twice, which led to an assertion failure when asserts against it were added by this patch. mysql-test/r/grant.result: Fix the patch for Bug 16470, now FLUSH PRIVILEGES produces an error if mysql.procs_priv is missing. This fixes the assert that send_ok() must not called after send_error() (the original patch for Bug 16470 was prone to this). mysql-test/suite/rpl/r/rpl_row_tabledefs_2myisam.result: Produce a more detailed error message. mysql-test/suite/rpl/r/rpl_row_tabledefs_3innodb.result: Produce a more detailed error message. mysql-test/t/grant.test: Update the test, now FLUSH PRIVILEGES returns an error if mysql.procs_priv is missing. server-tools/instance-manager/mysql_connection.cc: Rename net.last_errno to net.client_last_errno. sql/ha_ndbcluster_binlog.cc: Add asserts. Use getters to access statement status information. Add a comment why run_query() is broken. Reset the diagnostics area in the end of run_query() to fulfill the invariant that the diagnostics_area is never assigned twice per statement (see the comment in the code when this can happen). We still do not clear thd->is_fatal_error and thd->is_slave_error, which may lead to bugs, I consider the whole affair as something to be dealt with separately. sql/ha_partition.cc: fatal_error() doesn't set an error by itself. Perhaps we should remove this method altogether and instead add a flag to my_error to set thd->is_fatal_error property. Meanwhile, this change is a part of inspection made to the entire source code with the goal to ensure that fatal_error() is always accompanied by my_error(). sql/item_func.cc: There is no net.last_error anymore. Remove the obsolete assignment. sql/log_event.cc: Use getters to access statement error status information. sql/log_event_old.cc: Use getters to access statement error status information. sql/mysqld.cc: Previously, if a continue handler for an error was found, my_message_sql() would not set an error in THD. Since the current statement must be aborted in any case, find_handler() had a hack to assign thd->net.report_error to 1. Remove this hack. Set an error in my_message_sql() even if the continue handler is found. The error will be cleared anyway when the handler is executed. This is one action among many in this patch to ensure the invariant that whenever thd->is_error() is TRUE, we have a message in thd->main_da.message(). sql/net_serv.cc: Use a full-blown my_error() in net_serv.cc to report an error, instead of just setting net->last_errno. This ensures the invariant that whenever thd->is_error() returns TRUE, we have a message in thd->main_da.message(). Remove initialization of removed NET members. sql/opt_range.cc: Use my_error() instead of just raising thd->net.report_error. This ensures the invariant that whenever thd->is_error() returns TRUE, there is a message in thd->main_da.message(). sql/opt_sum.cc: Move invocation of fatal_error() right next to the place where we set the error message. That makes it easier to track that whenever fatal_error() is called, there is a message in THD. sql/protocol.cc: Rename send_ok() and send_eof() to net_send_ok() and net_send_eof() respectively. These functions write directly to the network and are not for use anywhere outside the client/server protocol code. Remove the code that was responsible for cases when either there is no error code, or no error message, or both. Instead the calling code ensures that they are always present. Asserts are added to enforce the invariant. Instead of a direct access to thd->server_status and thd->total_warn_count use function parameters, since these from now on don't always come directly from THD. Introduce net_end_statement(), the single-entry-point replacement API for send_ok(), send_eof() and net_send_error(). Implement Protocol::end_partial_result_set to use in select_send::abort() when there is a continue handler. sql/protocol.h: Update declarations. sql/repl_failsafe.cc: Use getters to access statement status information in THD. Rename net.last_error to net.client_last_error. sql/rpl_record.cc: Set an error message in prepare_record() if there is no default value for the field -- later we do print this message to the client. sql/rpl_rli.cc: Use getters to access statement status information in THD. sql/slave.cc: In create_table_from_dump() (a common function that is used in LOAD MASTER TABLE SQL statement and COM_LOAD_MASTER_DATA), instead of hacks with no_send_ok, clear the diagnostics area when mysql_rm_table() succeeded. Update has_temporary_error() to work correctly when no error is set. This is the case when Incident_log_event is executed: it always returns an error but does not set an error message. Use getters to access error status information. sql/sp_head.cc: Instead of hacks with no_send_error, work through the diagnostics area interface to suppress sending of OK/ERROR packets to the client. Move query_cache_end_of_result before log_slow_statement(), similarly to how it's done in dispatch_command(). sql/sp_rcontext.cc: Remove hacks with assignment of thd->net.report_error, they are not necessary any more (see the changes in mysqld.cc). sql/sql_acl.cc: Use getters to access error status information in THD. sql/sql_base.cc: Access thd->main_da.sql_errno() only if there is an error. This fixes a bug when auto-discovery, that was effectively disabled under pre-locking. sql/sql_binlog.cc: Remove hacks with no_send_ok/no_send_error, they are not necessary anymore: the caller is responsible for network communication. sql/sql_cache.cc: Disable sending of OK/ERROR/EOF packet in the end of dispatch_command if the response has been served from the query cache. This raises the question whether we should store EOF packet in the query cache at all, or generate it anew for each statement (we should generate it anew), but this is to be addressed separately. sql/sql_class.cc: Implement class Diagnostics_area. Please see comments in sql_class.h for details. Fix a subtle coding mistake in select_send::send_data: when on slave, an error in Item::send() was ignored. The problem became visible due to asserts that the diagnostics area is never double assigned. Remove initialization of removed NET members. In select_send::abort() do not call select_send::send_eof(). This is not inheritance-safe. Even if a stored procedure continue handler is found, the current statement is aborted, not succeeded. Instead introduce a Protocol API to send the required response, Protocol::end_partial_result_set(). This simplifies implementation of select_send::send_eof(). No need to add more asserts that there is no error, there is an assert inside Diagnostics_area::set_ok_status() already. Leave no trace of no_send_* in the code. sql/sql_class.h: Declare class Diagnostics_area. Remove the hack with no_send_ok from Substatement_state. Provide inline implementations of send_ok/send_eof. Add commetns. sql/sql_connect.cc: Remove hacks with no_send_error. Since now an error in THD is always set if net->error, it's not necessary to check both net->error and thd->is_error() in the do_command loop. Use thd->main_da.message() instead of net->last_errno. Remove the hack with is_slave_error in sys_init_connect. Since now we do not reset the diagnostics area in net_send_error (it's reset at the beginning of the next statement), we can access it safely even after execute_init_command. sql/sql_db.cc: Update the code to satisfy the invariant that the diagnostics area is never assigned twice. Incidentally, this fixes Bug 29958 "Weird message on DROP DATABASE if mysql.proc does not exist". sql/sql_delete.cc: Change multi-delete to abort in abort(), as per select_send protocol. Fixes the merge error with the test for Bug 29136 sql/sql_derived.cc: Use getters to access error information. sql/sql_insert.cc: Use getters to access error information. sql-common/client.c: Rename last_error to client_last_error, last_errno to client_last_errno. sql/sql_parse.cc: Remove hacks with no_send_error. Deploy net_end_statement(). The story of COM_SHUTDOWN is interesting. Long story short, the server would become on its death's door, and only no_send_ok/no_send_error assigned by send_ok()/net_send_error() would hide its babbling from the client. First of all, COM_QUIT does not require a response. So, the comment saying "Let's send a response to possible COM_QUIT" is not only groundless (even mysqladmin shutdown/mysql_shutdown() doesn't send COM_QUIT after COM_SHUTDOWN), it's plainly incorrect. Secondly, besides this additional 'OK' packet to respond to a hypothetical COM_QUIT, there was the following code in dispatch_command(): if (thd->killed) thd->send_kill_message(); if (thd->is_error() net_send_error(thd); This worked out really funny for the thread through which COM_SHUTDOWN was delivered: we would get COM_SHUTDOWN, say okay, say okay again, kill everybody, get the kill signal ourselves, and then attempt to say "Server shutdown in progress" to the client that is very likely long gone. This all became visible when asserts were added that the Diagnostics_area is not assigned twice. Move query_cache_end_of_result() to the end of dispatch_command(), since net_send_eof() has been moved there. This is safe, query_cache_end_of_result() is a no-op if there is no started query in the cache. Consistently use select_send interface to call abort() or send_eof() depending on the operation result. Remove thd->fatal_error() from reset_master(), it was a no-op. in hacks with no_send_error woudl save us from complete breakage of the client/server protocol. Consistently use select_send::abort() whenever there is an error, and select_send::send_eof() in case of success. The issue became visible due to added asserts. sql/sql_partition.cc: Always set an error in THD whenever there is a call to fatal_error(). sql/sql_prepare.cc: Deploy class Diagnostics_area. Remove the unnecessary juggling with the protocol in Select_fetch_protocol_binary::send_eof(). EOF packet format is protocol-independent. sql/sql_select.cc: Call fatal_error() directly in opt_sum_query. Call my_error() whenever we call thd->fatal_error(). sql/sql_servers.cc: Use getters to access error information in THD. sql/sql_show.cc: Use getters to access error information in THD. Add comments. Call my_error() whenever we call fatal_error(). sql/sql_table.cc: Replace hacks with no_send_ok with the interface of the diagnostics area. Clear the error if ENOENT error in ha_delete_table(). sql/sql_update.cc: Introduce multi_update::abort(), which is the proper way to abort a multi-update. This fixes the merge conflict between this patch and the patch for Bug 29136. sql/table.cc: Use a getter to access error information in THD. sql/tztime.cc: Use a getter to access error information in THD.

BUG#21842 (Cluster fails to replicate to innodb or myisam with err 134 using TPC-B): Problem: A RBR event can contain incomplete row data (only key value and fields which have been changed). In that case, when the row is unpacked into record and written to a table, the missing fields get incorrect NULL values leading to master-slave inconsistency. Solution: Use values found in slave's table for columns which are not given in the rows event.

The code for writing a single row uses the following algorithm: 1. unpack row_data into table->record[0], 2. try to insert record, 3. if duplicate record found, fetch it into table->record[0], 4. unpack row_data into table->record[0], 5. write table->record[0] into the table. Where row_data is the row as stored in the data area of a rows event. Thus: a) unpacking of row_data happens at the time when row is written into a table, b) when unpacking (in step 4), only columns present in row_data are overwritten - all other columns remain as they were found in the table. Since all data needed for the above algorithm is stored inside Rows_log_event class, functions which locate and write rows are turned into methods of that class. replace_record() -> Rows_log_event::write_row() find_and_fetch_row() -> Rows_log_event::find_row() Both methods take row data from event's data buffer - the row being processed is pointed by m_curr_row. They unpack the data as needed into table's record buffers record[0] or record[1]. When row is unpacked, m_curr_row_end is set to point at next row in the data buffer. Other changes introduced in this changeset: - Change signature of unpack_row(): don't report errors and don't setup table's rw_set here. Errors can happen only when setting default values in prepare_record() function and are detected there. - In Rows_log_event and derived classes, don't pass arguments to the execution primitives (do_...() member functions) but use class members instead. - Move old row handling code into log_event_old.cc to be used by *_rows_log_event_old classes. Also, a new test rpl_ndb_2other is added which tests basic replication from master using ndb tables to slave storing the same tables using (possibly) different engine (myisam,innodb). Test is based on existing tests rpl_ndb_2myisam and rpl_ndb_2innodb. However, these tests doesn't work for various reasons and currently are disabled (see BUG#19227). The new test differs from the ones it is based on as follows: 1. Single test tests replication with different storage engines on slave (myisam, innodb, ndb). 2. Include file extra/rpl_tests/rpl_ndb_2multi_eng.test containing original tests is replaced by extra/rpl_tests/rpl_ndb_2multi_basic.test which doesn't contain tests using partitioned tables as these don't work currently. Instead, it tests replication to a slave which has more or less columns than master. 3. Include file include/rpl_multi_engine3.inc is replaced with include/rpl_multi_engine2.inc. The later differs by performing slightly different operations (updating more than one row in the table) and clearing table with "TRUNCATE TABLE" statement instead of "DELETE FROM" as replication of "DELETE" doesn't work well in this setting. 4. Slave must use option --log-slave-updates=0 as otherwise execution of replication events generated by ndb fails if table uses a different storage engine on slave (see BUG#29569). sql/log_event.cc: - Initialization of new Rows_log_event members. - Fixing some typos in documentation. In Rows_log_event::do_apply_event: - Set COMPLETE_ROWS_F flag (when master and slave have the same number of columns and all colums are present in the row) - Move initialization of tables write/read sets here, outside the rows processing loop (and out of unpack_row() function). - Remove calls to do_prepare_row() - no longer needed. - Add code managing m_curr_row and m_curr_row_end pointers. - Change signatures of row processing methods of Rows_log_event and it descendants - now most arguments are taken from class members. - Remove do_prepare_row() methods which are no longer used. - The auto_afree_ptr template is moved to rpl_utility.h (so that it can be used in log_event_old.cc). - Removed copy_extra_fields() function - no longer used. In Rows_log_event::write_row (former replace_record): - The old code is moved to log_event_old.cc. - Use prepare_record() and non-destructive unpack_current_row() to fill record with data. - In case a record being inserted already exists on slave and row data is incomplete use the record found and non-destructive unpack_current_row() to combine new column values with existing ones. - More debug info added. In Rows_log_event::find_row (former find_and_fetch_row function): - The old code is moved to log_event_old.cc. - Unpacking of the row is moved here. - In case of search using PK, the key data is prepared here. - More debug info added. - Remove initialization of Rows_log_event::m_after_image buffer which is no longer used. - Use new row unpacking methods in Update_rows_log_event::do_exec_row() to create before and after image. Note: all existing code used by Rows_log_event::do_apply_event() has been moved to log_event_old.cc to be used by *_rows_log_event_old classes. sql/log_event.h: - Add new COMPLETE_ROWS_F flag in Rows_log_event. - Add Rows_log_event members describing the row being processed. - Add a pointer to key buffer which is used in derived classes. - Add new methods: find__row(), write_row() and unpack_current_row(). - Change signatures of do_...() methods (replace method arguments by class members). - Remove do_prepare_row() method which is no longer used. - Update method documentation. - Add Old_rows_log_event class, which contains the old row processing code, as a friend of Rows_log_event so that it can access all members of an event instance. sql/log_event_old.cc: Move here old implementation of Rows_log_event::do_apply_event() and helper methods. sql/log_event_old.h: - Define new class Old_rows_log_event encapsulating old version of Rows_log_event::do_apply_event() and the helper methods. - Add the Old_rows_log_event class as a base for *_old versions of RBR event classes, ensure that the old version of do_apply_event() is called. - For *_old classes, declare the helper methods used in the old version of do_apply_event(). sql/rpl_record.cc: - Make unpack_row non-destructive for columns not present in the row. - Don't fill read/write set here as it is done outside these functions. - Move initialization of a record with default values to a separate function prepare_record(). sql/rpl_record.h: - Change signature of unpack_row(). - Declare function prepare_record(). sql/rpl_utility.cc: Make tabe_def::calc_field_size() a const method. sql/rpl_utility.h: Make table_def::calc_field_size() a const method. Move auto_afree_ptr template here so that it can be re-used (currently in log_event.cc and log_event_old.cc). Similar with DBUG_PRINT_BITSET macro. mysql-test/extra/rpl_tests/rpl_ndb_2multi_basic.test: Modification of rpl_ndb_2multi_eng test. Tests with partitioned tables are removed and a setup with slave having different number of columns than master is added. mysql-test/include/rpl_multi_engine2.inc: Modification of rpl_multi_engine3.inc which operates on more rows and replaces "DELETE FROM t1" with "TRUNCATE TABLE t1" as the first form doesn't replicate in NDB -> non-NDB setting (BUG#28538). mysql-test/suite/rpl_ndb/r/rpl_ndb_2other.result: Results of the test. mysql-test/suite/rpl_ndb/t/rpl_ndb_2other-slave.opt: Test options. --log-slave-updates=0 is compulsory as otherwise non-NDB slave applying row events from NDB master will fail when trying to log them. mysql-test/suite/rpl_ndb/t/rpl_ndb_2other.test: Test replication of NDB table to slave using other engine.

BUG#31581: 5.1-telco-6.1 -> 5.1.22. Slave crashes during starting This patch has two purposes: (1) To refactor the code so that {Write|Update|Delete}_rows_log_event_old does not use code from {Write|Update|Delete}_rows_log_event. Before refactoring there was the following problem: whenever we modifed the code for new events, it affected the old events. This is bad, as it makes maintainance difficult. After refactoring, we can safely edit the new code without affecting old events. So, if we for instance modify the binary format of new events, we no longer need to worry about how the new code reads old events. (2) To fix BUG#31581. These two objectives are reached by the following changes: - Merged Rows_log_event into Old_rows_log_event and {Write|Update|Delete}_rows_log_event into {Write|Update|Delete}_rows_log_event_old. - Fixed the bug by replacing {WRITE|UPDATE|DELETE}_ROWS_EVENT by PRE_GA_{WRITE|UPDATE|DELETE}_ROWS_EVENT. - Added comments to log_event_old.h (This patch is identical to the previously committed patch which was a collapse of three changesets, except that it adds assert(0) to constructors for old types of row log events that should never be called.) sql/log_event_old.cc: Merged Rows_log_event into Old_rows_log_event and {Write|Update|Delete}_rows_log_event into {Write|Update|Delete}_rows_log_event_old. Also fixed the bug by replacing {WRITE|UPDATE|DELETE}_ROWS_EVENT by PRE_GA_{WRITE|UPDATE|DELETE}_ROWS_EVENT. sql/log_event_old.h: Merged Rows_log_event into Old_rows_log_event and {Write|Update|Delete}_rows_log_event into {Write|Update|Delete}_rows_log_event_old.

BUG#31581: 5.1-telco-6.1 -> 5.1.22. Slave crashes during starting This patch has two purposes: (1) To refactor the code so that {Write|Update|Delete}_rows_log_event_old does not use code from {Write|Update|Delete}_rows_log_event. Before refactoring there was the following problem: whenever we modifed the code for new events, it affected the old events. This is bad, as it makes maintainance difficult. After refactoring, we can safely edit the new code without affecting old events. So, if we for instance modify the binary format of new events, we no longer need to worry about how the new code reads old events. (2) To fix BUG#31581. These two objectives are reached by the following changes: - Merged Rows_log_event into Old_rows_log_event and {Write|Update|Delete}_rows_log_event into {Write|Update|Delete}_rows_log_event_old. - Fixed the bug by replacing {WRITE|UPDATE|DELETE}_ROWS_EVENT by PRE_GA_{WRITE|UPDATE|DELETE}_ROWS_EVENT. - Added comments to log_event_old.h (This patch is identical to the previously committed patch which was a collapse of three changesets, except that it adds assert(0) to constructors for old types of row log events that should never be called.) sql/log_event_old.cc: Merged Rows_log_event into Old_rows_log_event and {Write|Update|Delete}_rows_log_event into {Write|Update|Delete}_rows_log_event_old. Also fixed the bug by replacing {WRITE|UPDATE|DELETE}_ROWS_EVENT by PRE_GA_{WRITE|UPDATE|DELETE}_ROWS_EVENT. sql/log_event_old.h: Merged Rows_log_event into Old_rows_log_event and {Write|Update|Delete}_rows_log_event into {Write|Update|Delete}_rows_log_event_old. Also added comment explaining what the file contains and what the classes do.

BUG#21842 (Cluster fails to replicate to innodb or myisam with err 134 using TPC-B): Problem: A RBR event can contain incomplete row data (only key value and fields which have been changed). In that case, when the row is unpacked into record and written to a table, the missing fields get incorrect NULL values leading to master-slave inconsistency. Solution: Use values found in slave's table for columns which are not given in the rows event. The code for writing a single row uses the following algorithm: 1. unpack row_data into table->record[0], 2. try to insert record, 3. if duplicate record found, fetch it into table->record[0], 4. unpack row_data into table->record[0], 5. write table->record[0] into the table. Where row_data is the row as stored in the data area of a rows event. Thus: a) unpacking of row_data happens at the time when row is written into a table, b) when unpacking (in step 4), only columns present in row_data are overwritten - all other columns remain as they were found in the table. Since all data needed for the above algorithm is stored inside Rows_log_event class, functions which locate and write rows are turned into methods of that class. replace_record() -> Rows_log_event::write_row() find_and_fetch_row() -> Rows_log_event::find_row() Both methods take row data from event's data buffer - the row being processed is pointed by m_curr_row. They unpack the data as needed into table's record buffers record[0] or record[1]. When row is unpacked, m_curr_row_end is set to point at next row in the data buffer. Other changes introduced in this changeset: - Change signature of unpack_row(): don't report errors and don't setup table's rw_set here. Errors can happen only when setting default values in prepare_record() function and are detected there. - In Rows_log_event and derived classes, don't pass arguments to the execution primitives (do_...() member functions) but use class members instead. - Move old row handling code into log_event_old.cc to be used by *_rows_log_event_old classes. Also, a new test rpl_ndb_2other is added which tests basic replication from master using ndb tables to slave storing the same tables using (possibly) different engine (myisam,innodb). Test is based on existing tests rpl_ndb_2myisam and rpl_ndb_2innodb. However, these tests doesn't work for various reasons and currently are disabled (see BUG#19227). The new test differs from the ones it is based on as follows: 1. Single test tests replication with different storage engines on slave (myisam, innodb, ndb). 2. Include file extra/rpl_tests/rpl_ndb_2multi_eng.test containing original tests is replaced by extra/rpl_tests/rpl_ndb_2multi_basic.test which doesn't contain tests using partitioned tables as these don't work currently. Instead, it tests replication to a slave which has more or less columns than master. 3. Include file include/rpl_multi_engine3.inc is replaced with include/rpl_multi_engine2.inc. The later differs by performing slightly different operations (updating more than one row in the table) and clearing table with "TRUNCATE TABLE" statement instead of "DELETE FROM" as replication of "DELETE" doesn't work well in this setting. 4. Slave must use option --log-slave-updates=0 as otherwise execution of replication events generated by ndb fails if table uses a different storage engine on slave (see BUG#29569). sql/log_event.cc: - Initialization of new Rows_log_event members. - Fixing some typos in documentation. In Rows_log_event::do_apply_event: - Set COMPLETE_ROWS_F flag (when master and slave have the same number of columns and all colums are present in the row) - Move initialization of tables write/read sets here, outside the rows processing loop (and out of unpack_row() function). - Remove calls to do_prepare_row() - no longer needed. - Add code managing m_curr_row and m_curr_row_end pointers. - Change signatures of row processing methods of Rows_log_event and it descendants - now most arguments are taken from class members. - Remove do_prepare_row() methods which are no longer used. - The auto_afree_ptr template is moved to rpl_utility.h (so that it can be used in log_event_old.cc). - Removed copy_extra_fields() function - no longer used. In Rows_log_event::write_row (former replace_record): - The old code is moved to log_event_old.cc. - Use prepare_record() and non-destructive unpack_current_row() to fill record with data. - In case a record being inserted already exists on slave and row data is incomplete use the record found and non-destructive unpack_current_row() to combine new column values with existing ones. - More debug info added. In Rows_log_event::find_row (former find_and_fetch_row function): - The old code is moved to log_event_old.cc. - Unpacking of the row is moved here. - In case of search using PK, the key data is prepared here. - More debug info added. - Remove initialization of Rows_log_event::m_after_image buffer which is no longer used. - Use new row unpacking methods in Update_rows_log_event::do_exec_row() to create before and after image. Note: all existing code used by Rows_log_event::do_apply_event() has been moved to log_event_old.cc to be used by *_rows_log_event_old classes. sql/log_event.h: - Add new COMPLETE_ROWS_F flag in Rows_log_event. - Add Rows_log_event members describing the row being processed. - Add a pointer to key buffer which is used in derived classes. - Add new methods: find__row(), write_row() and unpack_current_row(). - Change signatures of do_...() methods (replace method arguments by class members). - Remove do_prepare_row() method which is no longer used. - Update method documentation. - Add Old_rows_log_event class, which contains the old row processing code, as a friend of Rows_log_event so that it can access all members of an event instance. sql/log_event_old.cc: Move here old implementation of Rows_log_event::do_apply_event() and helper methods. sql/log_event_old.h: - Define new class Old_rows_log_event encapsulating old version of Rows_log_event::do_apply_event() and the helper methods. - Add the Old_rows_log_event class as a base for *_old versions of RBR event classes, ensure that the old version of do_apply_event() is called. - For *_old classes, declare the helper methods used in the old version of do_apply_event(). sql/rpl_record.cc: - Make unpack_row non-destructive for columns not present in the row. - Don't fill read/write set here as it is done outside these functions. - Move initialization of a record with default values to a separate function prepare_record(). sql/rpl_record.h: - Change signature of unpack_row(). - Declare function prepare_record(). sql/rpl_utility.cc: Make tabe_def::calc_field_size() a const method. sql/rpl_utility.h: Make table_def::calc_field_size() a const method. Move auto_afree_ptr template here so that it can be re-used (currently in log_event.cc and log_event_old.cc). Similar with DBUG_PRINT_BITSET macro. mysql-test/extra/rpl_tests/rpl_ndb_2multi_basic.test: Modification of rpl_ndb_2multi_eng test. Tests with partitioned tables are removed and a setup with slave having different number of columns than master is added. mysql-test/include/rpl_multi_engine2.inc: Modification of rpl_multi_engine3.inc which operates on more rows and replaces "DELETE FROM t1" with "TRUNCATE TABLE t1" as the first form doesn't replicate in NDB -> non-NDB setting (BUG#28538). mysql-test/suite/rpl_ndb/r/rpl_ndb_2other.result: Results of the test. mysql-test/suite/rpl_ndb/t/rpl_ndb_2other-slave.opt: Test options. --log-slave-updates=0 is compulsory as otherwise non-NDB slave applying row events from NDB master will fail when trying to log them. mysql-test/suite/rpl_ndb/t/rpl_ndb_2other.test: Test replication of NDB table to slave using other engine. The main test is in extra/rpl_tests/rpl_ndb_2multi_basic.test. It is included here several times with different settings of default storage engine on slave.

BUG#21842 (Cluster fails to replicate to innodb or myisam with err 134 using TPC-B): Problem: A RBR event can contain incomplete row data (only key value and fields which have been changed). In that case, when the row is unpacked into record and written to a table, the missing fields get incorrect NULL values leading to master-slave inconsistency. Solution: Use values found in slave's table for columns which are not given in the rows event. The code for writing a single row uses the following algorithm: 1. unpack row_data into table->record[0], 2. try to insert record, 3. if duplicate record found, fetch it into table->record[0], 4. unpack row_data into table->record[0], 5. write table->record[0] into the table. Where row_data is the row as stored in the data area of a rows event. Thus: a) unpacking of row_data happens at the time when row is written into a table, b) when unpacking (in step 4), only columns present in row_data are overwritten - all other columns remain as they were found in the table. Since all data needed for the above algorithm is stored inside Rows_log_event class, functions which locate and write rows are turned into methods of that class. replace_record() -> Rows_log_event::write_row() find_and_fetch_row() -> Rows_log_event::find_row() Both methods take row data from event's data buffer - the row being processed is pointed by m_curr_row. They unpack the data as needed into table's record buffers record[0] or record[1]. When row is unpacked, m_curr_row_end is set to point at next row in the data buffer. Other changes introduced in this changeset: - Change signature of unpack_row(): don't report errors and don't setup table's rw_set here. Errors can happen only when setting default values in prepare_record() function and are detected there. - In Rows_log_event and derived classes, don't pass arguments to the execution primitives (do_...() member functions) but use class members instead. - Move old row handling code into log_event_old.cc to be used by *_rows_log_event_old classes. Also, a new test rpl_ndb_2other is added which tests basic replication from master using ndb tables to slave storing the same tables using (possibly) different engine (myisam,innodb). Test is based on existing tests rpl_ndb_2myisam and rpl_ndb_2innodb. However, these tests doesn't work for various reasons and currently are disabled (see BUG#19227). The new test differs from the ones it is based on as follows: 1. Single test tests replication with different storage engines on slave (myisam, innodb, ndb). 2. Include file extra/rpl_tests/rpl_ndb_2multi_eng.test containing original tests is replaced by extra/rpl_tests/rpl_ndb_2multi_basic.test which doesn't contain tests using partitioned tables as these don't work currently. Instead, it tests replication to a slave which has more or less columns than master. 3. Include file include/rpl_multi_engine3.inc is replaced with include/rpl_multi_engine2.inc. The later differs by performing slightly different operations (updating more than one row in the table) and clearing table with "TRUNCATE TABLE" statement instead of "DELETE FROM" as replication of "DELETE" doesn't work well in this setting. 4. Slave must use option --log-slave-updates=0 as otherwise execution of replication events generated by ndb fails if table uses a different storage engine on slave (see BUG#29569). sql/log_event.cc: - Initialization of new Rows_log_event members. - Fixing some typos in documentation.

BUG#31581: 5.1-telco-6.1 -> 5.1.22. Slave crashes during starting This patch has two purposes: (1) To refactor the code so that {Write|Update|Delete}_rows_log_event_old does not use code from {Write|Update|Delete}_rows_log_event. Before refactoring there was the following problem: whenever we modifed the code for new events, it affected the old events. This is bad, as it makes maintainance difficult. After refactoring, we can safely edit the new code without affecting old events. So, if we for instance modify the binary format of new events, we no longer need to worry about how the new code reads old events. (2) To fix BUG#31581. These two objectives are reached by the following changes: - Merged Rows_log_event into Old_rows_log_event and {Write|Update|Delete}_rows_log_event into {Write|Update|Delete}_rows_log_event_old. - Fixed the bug by replacing {WRITE|UPDATE|DELETE}_ROWS_EVENT by PRE_GA_{WRITE|UPDATE|DELETE}_ROWS_EVENT. - Added comments to log_event_old.h (This patch is identical to the previously committed patch which was a collapse of three changesets, except that it adds assert(0) to constructors for old types of row log events that should never be called.) sql/log_event_old.cc: Merged Rows_log_event into Old_rows_log_event and {Write|Update|Delete}_rows_log_event into {Write|Update|Delete}_rows_log_event_old. Also fixed the bug by replacing {WRITE|UPDATE|DELETE}_ROWS_EVENT by PRE_GA_{WRITE|UPDATE|DELETE}_ROWS_EVENT. sql/log_event_old.h: Merged Rows_log_event into Old_rows_log_event and {Write|Update|Delete}_rows_log_event into {Write|Update|Delete}_rows_log_event_old. Also added comment explaining what the file contains and what the classes do.

e.g., the mysql.proc table since the correct record *shall* be
found using the primary key *only*. There shall be no

BUG#21842 (Cluster fails to replicate to innodb or myisam with err 134 using TPC-B): Problem: A RBR event can contain incomplete row data (only key value and fields which have been changed). In that case, when the row is unpacked into record and written to a table, the missing fields get incorrect NULL values leading to master-slave inconsistency. Solution: Use values found in slave's table for columns which are not given in the rows event. The code for writing a single row uses the following algorithm: 1. unpack row_data into table->record[0], 2. try to insert record, 3. if duplicate record found, fetch it into table->record[0], 4. unpack row_data into table->record[0], 5. write table->record[0] into the table. Where row_data is the row as stored in the data area of a rows event. Thus: a) unpacking of row_data happens at the time when row is written into a table, b) when unpacking (in step 4), only columns present in row_data are overwritten - all other columns remain as they were found in the table. Since all data needed for the above algorithm is stored inside Rows_log_event class, functions which locate and write rows are turned into methods of that class. replace_record() -> Rows_log_event::write_row() find_and_fetch_row() -> Rows_log_event::find_row() Both methods take row data from event's data buffer - the row being processed is pointed by m_curr_row. They unpack the data as needed into table's record buffers record[0] or record[1]. When row is unpacked, m_curr_row_end is set to point at next row in the data buffer. Other changes introduced in this changeset: - Change signature of unpack_row(): don't report errors and don't setup table's rw_set here. Errors can happen only when setting default values in prepare_record() function and are detected there. - In Rows_log_event and derived classes, don't pass arguments to the execution primitives (do_...() member functions) but use class members instead. - Move old row handling code into log_event_old.cc to be used by *_rows_log_event_old classes. Also, a new test rpl_ndb_2other is added which tests basic replication from master using ndb tables to slave storing the same tables using (possibly) different engine (myisam,innodb). Test is based on existing tests rpl_ndb_2myisam and rpl_ndb_2innodb. However, these tests doesn't work for various reasons and currently are disabled (see BUG#19227). The new test differs from the ones it is based on as follows: 1. Single test tests replication with different storage engines on slave (myisam, innodb, ndb). 2. Include file extra/rpl_tests/rpl_ndb_2multi_eng.test containing original tests is replaced by extra/rpl_tests/rpl_ndb_2multi_basic.test which doesn't contain tests using partitioned tables as these don't work currently. Instead, it tests replication to a slave which has more or less columns than master. 3. Include file include/rpl_multi_engine3.inc is replaced with include/rpl_multi_engine2.inc. The later differs by performing slightly different operations (updating more than one row in the table) and clearing table with "TRUNCATE TABLE" statement instead of "DELETE FROM" as replication of "DELETE" doesn't work well in this setting. 4. Slave must use option --log-slave-updates=0 as otherwise execution of replication events generated by ndb fails if table uses a different storage engine on slave (see BUG#29569). sql/log_event.cc: - Initialization of new Rows_log_event members. - Fixing some typos in documentation. In Rows_log_event::do_apply_event: - Set COMPLETE_ROWS_F flag (when master and slave have the same number of columns and all colums are present in the row) - Move initialization of tables write/read sets here, outside the rows processing loop (and out of unpack_row() function). - Remove calls to do_prepare_row() - no longer needed. - Add code managing m_curr_row and m_curr_row_end pointers. - Change signatures of row processing methods of Rows_log_event and it descendants - now most arguments are taken from class members. - Remove do_prepare_row() methods which are no longer used. - The auto_afree_ptr template is moved to rpl_utility.h (so that it can be used in log_event_old.cc). - Removed copy_extra_fields() function - no longer used. In Rows_log_event::write_row (former replace_record): - The old code is moved to log_event_old.cc. - Use prepare_record() and non-destructive unpack_current_row() to fill record with data. - In case a record being inserted already exists on slave and row data is incomplete use the record found and non-destructive unpack_current_row() to combine new column values with existing ones. - More debug info added. In Rows_log_event::find_row (former find_and_fetch_row function): - The old code is moved to log_event_old.cc. - Unpacking of the row is moved here. - In case of search using PK, the key data is prepared here. - More debug info added. - Remove initialization of Rows_log_event::m_after_image buffer which is no longer used. - Use new row unpacking methods in Update_rows_log_event::do_exec_row() to create before and after image. Note: all existing code used by Rows_log_event::do_apply_event() has been moved to log_event_old.cc to be used by *_rows_log_event_old classes. sql/log_event.h: - Add new COMPLETE_ROWS_F flag in Rows_log_event. - Add Rows_log_event members describing the row being processed. - Add a pointer to key buffer which is used in derived classes. - Add new methods: find__row(), write_row() and unpack_current_row(). - Change signatures of do_...() methods (replace method arguments by class members). - Remove do_prepare_row() method which is no longer used. - Update method documentation. - Add Old_rows_log_event class, which contains the old row processing code, as a friend of Rows_log_event so that it can access all members of an event instance. sql/log_event_old.cc: Move here old implementation of Rows_log_event::do_apply_event() and helper methods. sql/log_event_old.h: - Define new class Old_rows_log_event encapsulating old version of Rows_log_event::do_apply_event() and the helper methods. - Add the Old_rows_log_event class as a base for *_old versions of RBR event classes, ensure that the old version of do_apply_event() is called. - For *_old classes, declare the helper methods used in the old version of do_apply_event(). sql/rpl_record.cc: - Make unpack_row non-destructive for columns not present in the row. - Don't fill read/write set here as it is done outside these functions. - Move initialization of a record with default values to a separate function prepare_record(). sql/rpl_record.h: - Change signature of unpack_row(). - Declare function prepare_record(). sql/rpl_utility.cc: Make tabe_def::calc_field_size() a const method. sql/rpl_utility.h: Make table_def::calc_field_size() a const method. Move auto_afree_ptr template here so that it can be re-used (currently in log_event.cc and log_event_old.cc). Similar with DBUG_PRINT_BITSET macro. mysql-test/extra/rpl_tests/rpl_ndb_2multi_basic.test: Modification of rpl_ndb_2multi_eng test. Tests with partitioned tables are removed and a setup with slave having different number of columns than master is added. mysql-test/include/rpl_multi_engine2.inc: Modification of rpl_multi_engine3.inc which operates on more rows and replaces "DELETE FROM t1" with "TRUNCATE TABLE t1" as the first form doesn't replicate in NDB -> non-NDB setting (BUG#28538). mysql-test/suite/rpl_ndb/r/rpl_ndb_2other.result: Results of the test. mysql-test/suite/rpl_ndb/t/rpl_ndb_2other-slave.opt: Test options. --log-slave-updates=0 is compulsory as otherwise non-NDB slave applying row events from NDB master will fail when trying to log them. mysql-test/suite/rpl_ndb/t/rpl_ndb_2other.test: Test replication of NDB table to slave using other engine.

BUG#21842 (Cluster fails to replicate to innodb or myisam with err 134 using TPC-B): Problem: A RBR event can contain incomplete row data (only key value and fields which have been changed). In that case, when the row is unpacked into record and written to a table, the missing fields get incorrect NULL values leading to master-slave inconsistency. Solution: Use values found in slave's table for columns which are not given in the rows event. The code for writing a single row uses the following algorithm: 1. unpack row_data into table->record[0], 2. try to insert record, 3. if duplicate record found, fetch it into table->record[0], 4. unpack row_data into table->record[0], 5. write table->record[0] into the table. Where row_data is the row as stored in the data area of a rows event. Thus: a) unpacking of row_data happens at the time when row is written into a table, b) when unpacking (in step 4), only columns present in row_data are overwritten - all other columns remain as they were found in the table. Since all data needed for the above algorithm is stored inside Rows_log_event class, functions which locate and write rows are turned into methods of that class. replace_record() -> Rows_log_event::write_row() find_and_fetch_row() -> Rows_log_event::find_row() Both methods take row data from event's data buffer - the row being processed is pointed by m_curr_row. They unpack the data as needed into table's record buffers record[0] or record[1]. When row is unpacked, m_curr_row_end is set to point at next row in the data buffer. Other changes introduced in this changeset: - Change signature of unpack_row(): don't report errors and don't setup table's rw_set here. Errors can happen only when setting default values in prepare_record() function and are detected there. - In Rows_log_event and derived classes, don't pass arguments to the execution primitives (do_...() member functions) but use class members instead. - Move old row handling code into log_event_old.cc to be used by *_rows_log_event_old classes. Also, a new test rpl_ndb_2other is added which tests basic replication from master using ndb tables to slave storing the same tables using (possibly) different engine (myisam,innodb). Test is based on existing tests rpl_ndb_2myisam and rpl_ndb_2innodb. However, these tests doesn't work for various reasons and currently are disabled (see BUG#19227). The new test differs from the ones it is based on as follows: 1. Single test tests replication with different storage engines on slave (myisam, innodb, ndb). 2.

BUG#31581: 5.1-telco-6.1 -> 5.1.22. Slave crashes during starting This patch has two purposes: (1) To refactor the code so that {Write|Update|Delete}_rows_log_event_old does not use code from {Write|Update|Delete}_rows_log_event. Before refactoring there was the following problem: whenever we modifed the code for new events, it affected the old events. This is bad, as it makes maintainance difficult. After refactoring, we can safely edit the new code without affecting old events. So, if we for instance modify the binary format of new events, we no longer need to worry about how the new code reads old events. (2) To fix BUG#31581. These two objectives are reached by the following changes: - Merged Rows_log_event into Old_rows_log_event and {Write|Update|Delete}_rows_log_event into {Write|Update|Delete}_rows_log_event_old. - Fixed the bug by replacing {WRITE|UPDATE|DELETE}_ROWS_EVENT by PRE_GA_{WRITE|UPDATE|DELETE}_ROWS_EVENT. - Added comments to log_event_old.h (This patch is identical to the previously committed patch which was a collapse of three changesets, except that it adds assert(0) to constructors for old types of row log events that should never be called.) sql/log_event_old.cc: Merged Rows_log_event into Old_rows_log_event and {Write|Update|Delete}_rows_log_event into {Write|Update|Delete}_rows_log_event_old. Also fixed the bug by replacing {WRITE|UPDATE|DELETE}_ROWS_EVENT by PRE_GA_{WRITE|UPDATE|DELETE}_ROWS_EVENT. sql/log_event_old.h: Merged Rows_log_event into Old_rows_log_event and {Write|Update|Delete}_rows_log_event into {Write|Update|Delete}_rows_log_event_old. Also added comment explaining what the file contains and what the classes do.

BUG#31581: 5.1-telco-6.1 -> 5.1.22. Slave crashes during starting This patch has two purposes: (1) To refactor the code so that {Write|Update|Delete}_rows_log_event_old does not use code from {Write|Update|Delete}_rows_log_event. Before refactoring there was the following problem: whenever we modifed the code for new events, it affected the old events. This is bad, as it makes maintainance difficult. After refactoring, we can safely edit the new code without affecting old events. So, if we for instance modify the binary format of new events, we no longer need to worry about how the new code reads old events. (2) To fix BUG#31581. These two objectives are reached by the following changes: - Merged Rows_log_event into Old_rows_log_event and {Write|Update|Delete}_rows_log_event into {Write|Update|Delete}_rows_log_event_old. - Fixed the bug by replacing {WRITE|UPDATE|DELETE}_ROWS_EVENT by PRE_GA_{WRITE|UPDATE|DELETE}_ROWS_EVENT. - Added comments to log_event_old.h (This patch is identical to the previously committed patch which was a collapse of three changesets, except that it adds assert(0) to constructors for old types of row log events that should never be called.) sql/log_event_old.cc: Merged Rows_log_event into Old_rows_log_event and {Write|Update|Delete}_rows_log_event into {Write|Update|Delete}_rows_log_event_old. Also fixed the bug by replacing {WRITE|UPDATE|DELETE}_ROWS_EVENT by PRE_GA_{WRITE|UPDATE|DELETE}_ROWS_EVENT. sql/log_event_old.h: Merged Rows_log_event into Old_rows_log_event and {Write|Update|Delete}_rows_log_event into {Write|Update|Delete}_rows_log_event_old. Also added comment explaining what the file contains and what the classes do.

BUG#21842 (Cluster fails to replicate to innodb or myisam with err 134 using TPC-B): Problem: A RBR event can contain incomplete row data (only key value and fields which have been changed). In that case, when the row is unpacked into record and written to a table, the missing fields get incorrect NULL values leading to master-slave inconsistency. Solution: Use values found in slave's table for columns which are not given in the rows event. The code for writing a single row uses the following algorithm: 1. unpack row_data into table->record[0], 2. try to insert record, 3. if duplicate record found, fetch it into table->record[0], 4. unpack row_data into table->record[0], 5. write table->record[0] into the table. Where row_data is the row as stored in the data area of a rows event. Thus: a) unpacking of row_data happens at the time when row is written into a table, b) when unpacking (in step 4), only columns present in row_data are overwritten - all other columns remain as they were found in the table. Since all data needed for the above algorithm is stored inside Rows_log_event class, functions which locate and write rows are turned into methods of that class. replace_record() -> Rows_log_event::write_row() find_and_fetch_row() -> Rows_log_event::find_row() Both methods take row data from event's data buffer - the row being processed is pointed by m_curr_row. They unpack the data as needed into table's record buffers record[0] or record[1]. When row is unpacked, m_curr_row_end is set to point at next row in the data buffer. Other changes introduced in this changeset: - Change signature of unpack_row(): don't report errors and don't setup table's rw_set here. Errors can happen only when setting default values in prepare_record() function and are detected there. - In Rows_log_event and derived classes, don't pass arguments to the execution primitives (do_...() member functions) but use class members instead. - Move old row handling code into log_event_old.cc to be used by *_rows_log_event_old classes. Also, a new test rpl_ndb_2other is added which tests basic replication from master using ndb tables to slave storing the same tables using (possibly) different engine (myisam,innodb). Test is based on existing tests rpl_ndb_2myisam and rpl_ndb_2innodb. However, these tests doesn't work for various reasons and currently are disabled (see BUG#19227). The new test differs from the ones it is based on as follows: 1. Single test tests replication with different storage engines on slave (myisam, innodb, ndb). 2. Include file extra/rpl_tests/rpl_ndb_2multi_eng.test containing original tests is replaced by extra/rpl_tests/rpl_ndb_2multi_basic.test which doesn't contain tests using partitioned tables as these don't work currently. Instead, it tests replication to a slave which has more or less columns than master. 3. Include file include/rpl_multi_engine3.inc is replaced with include/rpl_multi_engine2.inc. The later differs by performing slightly different operations (updating more than one row in the table) and clearing table with "TRUNCATE TABLE" statement instead of "DELETE FROM" as replication of "DELETE" doesn't work well in this setting. 4. Slave must use option --log-slave-updates=0 as otherwise execution of replication events generated by ndb fails if table uses a different storage engine on slave (see BUG#29569). sql/log_event.cc: - Initialization of new Rows_log_event members. - Fixing some typos in documentation. In Rows_log_event::do_apply_event: - Set COMPLETE_ROWS_F flag (when master and slave have the same number of columns and all colums are present in the row) - Move initialization of tables write/read sets here, outside the rows processing loop (and out of unpack_row() function). - Remove calls to do_prepare_row() - no longer needed. - Add code managing m_curr_row and m_curr_row_end pointers. - Change signatures of row processing methods of Rows_log_event and it descendants - now most arguments are taken from class members. - Remove do_prepare_row() methods which are no longer used. - The auto_afree_ptr template is moved to rpl_utility.h (so that it can be used in log_event_old.cc). - Removed copy_extra_fields() function - no longer used. In Rows_log_event::write_row (former replace_record): - The old code is moved to log_event_old.cc. - Use prepare_record() and non-destructive unpack_current_row() to fill record with data. - In case a record being inserted already exists on slave and row data is incomplete use the record found and non-destructive unpack_current_row() to combine new column values with existing ones. - More debug info added.

WL#3817: Simplify string / memory area types and make things more consistent (first part) The following type conversions was done: - Changed byte to uchar - Changed gptr to uchar* - Change my_string to char * - Change my_size_t to size_t - Change size_s to size_t Removed declaration of byte, gptr, my_string, my_size_t and size_s. Following function parameter changes was done: - All string functions in mysys/strings was changed to use size_t instead of uint for string lengths. - All read()/write() functions changed to use size_t (including vio). - All protocoll functions changed to use size_t instead of uint - Functions that used a pointer to a string length was changed to use size_t* - Changed malloc(), free() and related functions from using gptr to use void * as this requires fewer casts in the code and is more in line with how the standard functions work. - Added extra length argument to dirname_part() to return the length of the created string. - Changed (at least) following functions to take uchar* as argument: - db_dump() - my_net_write() - net_write_command() - net_store_data() - DBUG_DUMP() - decimal2bin() & bin2decimal() - Changed my_compress() and my_uncompress() to use size_t. Changed one argument to my_uncompress() from a pointer to a value as we only return one value (makes function easier to use). - Changed type of 'pack_data' argument to packfrm() to avoid casts. - Changed in readfrm() and writefrom(), ha_discover and handler::discover() the type for argument 'frmdata' to uchar** to avoid casts. - Changed most Field functions to use uchar* instead of char* (reduced a lot of casts). - Changed field->val_xxx(xxx, new_ptr) to take const pointers. Other changes: - Removed a lot of not needed casts - Added a few new cast required by other changes - Added some cast to my_multi_malloc() arguments for safety (as string lengths needs to be uint, not size_t). - Fixed all calls to hash-get-key functions to use size_t*. (Needed to be done explicitely as this conflict was often hided by casting the function to hash_get_key). - Changed some buffers to memory regions to uchar* to avoid casts. - Changed some string lengths from uint to size_t. - Changed field->ptr to be uchar* instead of char*. This allowed us to get rid of a lot of casts. - Some changes from true -> TRUE, false -> FALSE, unsigned char -> uchar - Include zlib.h in some files as we needed declaration of crc32() - Changed MY_FILE_ERROR to be (size_t) -1. - Changed many variables to hold the result of my_read() / my_write() to be size_t. This was needed to properly detect errors (which are returned as (size_t) -1). - Removed some very old VMS code - Changed packfrm()/unpackfrm() to not be depending on uint size (portability fix) - Removed windows specific code to restore cursor position as this causes slowdown on windows and we should not mix read() and pread() calls anyway as this is not thread safe. Updated function comment to reflect this. Changed function that depended on original behavior of my_pwrite() to itself restore the cursor position (one such case). - Added some missing checking of return value of malloc(). - Changed definition of MOD_PAD_CHAR_TO_FULL_LENGTH to avoid 'long' overflow. - Changed type of table_def::m_size from my_size_t to ulong to reflect that m_size is the number of elements in the array, not a string/memory length. - Moved THD::max_row_length() to table.cc (as it's not depending on THD). Inlined max_row_length_blob() into this function. - More function comments - Fixed some compiler warnings when compiled without partitions. - Removed setting of LEX_STRING() arguments in declaration (portability fix). - Some trivial indentation/variable name changes. - Some trivial code simplifications: - Replaced some calls to alloc_root + memcpy to use strmake_root()/strdup_root(). - Changed some calls from memdup() to strmake() (Safety fix) - Simpler loops in client-simple.c BitKeeper/etc/ignore: added libmysqld/ha_ndbcluster_cond.cc --- added debian/defs.mk debian/control

BUG#31581: 5.1-telco-6.1 -> 5.1.22. Slave crashes during starting This patch has two purposes: (1) To refactor the code so that {Write|Update|Delete}_rows_log_event_old does not use code from {Write|Update|Delete}_rows_log_event. Before refactoring there was the following problem: whenever we modifed the code for new events, it affected the old events. This is bad, as it makes maintainance difficult. After refactoring, we can safely edit the new code without affecting old events. So, if we for instance modify the binary format of new events, we no longer need to worry about how the new code reads old events. (2) To fix BUG#31581. These two objectives are reached by the following changes: - Merged Rows_log_event into Old_rows_log_event and {Write|Update|Delete}_rows_log_event into {Write|Update|Delete}_rows_log_event_old. - Fixed the bug by replacing {WRITE|UPDATE|DELETE}_ROWS_EVENT by PRE_GA_{WRITE|UPDATE|DELETE}_ROWS_EVENT. - Added comments to log_event_old.h (This patch is identical to the previously committed patch which was a collapse of three changesets, except that it adds assert(0) to constructors for old types of row log events that should never be called.) sql/log_event_old.cc: Merged Rows_log_event into Old_rows_log_event and {Write|Update|Delete}_rows_log_event into {Write|Update|Delete}_rows_log_event_old. Also fixed the bug by replacing {WRITE|UPDATE|DELETE}_ROWS_EVENT by PRE_GA_{WRITE|UPDATE|DELETE}_ROWS_EVENT. sql/log_event_old.h: Merged Rows_log_event into Old_rows_log_event and {Write|Update|Delete}_rows_log_event into {Write|Update|Delete}_rows_log_event_old. Also added comment explaining what the file contains and what the classes do.

BUG#21842 (Cluster fails to replicate to innodb or myisam with err 134 using TPC-B): Problem: A RBR event can contain incomplete row data (only key value and fields which have been changed). In that case, when the row is unpacked into record and written to a table, the missing fields get incorrect NULL values leading to master-slave inconsistency. Solution: Use values found in slave's table for columns which are not given in the rows event. The code for writing a single row uses the following algorithm: 1. unpack row_data into table->record[0], 2. try to insert record, 3. if duplicate record found, fetch it into table->record[0], 4. unpack row_data into table->record[0], 5. write table->record[0] into the table. Where row_data is the row as stored in the data area of a rows event. Thus: a) unpacking of row_data happens at the time when row is written into a table, b) when unpacking (in step 4), only columns present in row_data are overwritten - all other columns remain as they were found in the table. Since all data needed for the above algorithm is stored inside Rows_log_event class, functions which locate and write rows are turned into methods of that class. replace_record() -> Rows_log_event::write_row() find_and_fetch_row() -> Rows_log_event::find_row() Both methods take row data from event's data buffer - the row being processed is pointed by m_curr_row. They unpack the data as needed into table's record buffers record[0] or record[1]. When row is unpacked, m_curr_row_end is set to point at next row in the data buffer. Other changes introduced in this changeset: - Change signature of unpack_row(): don't report errors and don't setup table's rw_set here. Errors can happen only when setting default values in prepare_record() function and are detected there. - In Rows_log_event and derived classes, don't pass arguments to the execution primitives (do_...() member functions) but use class members instead. - Move old row handling code into log_event_old.cc to be used by *_rows_log_event_old classes. Also, a new test rpl_ndb_2other is added which tests basic replication from master using ndb tables to slave storing the same tables using (possibly) different engine (myisam,innodb). Test is based on existing tests rpl_ndb_2myisam and rpl_ndb_2innodb. However, these tests doesn't work for various reasons and currently are disabled (see BUG#19227). The new test differs from the ones it is based on as follows: 1. Single test tests replication with different storage engines on slave (myisam, innodb, ndb). 2. Include file extra/rpl_tests/rpl_ndb_2multi_eng.test containing original tests is replaced by extra/rpl_tests/rpl_ndb_2multi_basic.test which doesn't contain tests using partitioned tables as these don't work currently. Instead, it tests replication to a slave which has more or less columns than master. 3. Include file include/rpl_multi_engine3.inc is replaced with include/rpl_multi_engine2.inc. The later differs by performing slightly different operations (updating more than one row in the table) and clearing table with "TRUNCATE TABLE" statement instead of "DELETE FROM" as replication of "DELETE" doesn't work well in this setting. 4. Slave must use option --log-slave-updates=0 as otherwise execution of replication events generated by ndb fails if table uses a different storage engine on slave (see BUG#29569). sql/log_event.cc: - Initialization of new Rows_log_event members. - Fixing some typos in documentation. In Rows_log_event::do_apply_event: - Set COMPLETE_ROWS_F flag (when master and slave have the same number of columns and all colums are present in the row) - Move initialization of tables write/read sets here, outside the rows processing loop (and out of unpack_row() function). - Remove calls to do_prepare_row() - no longer needed. - Add code managing m_curr_row and m_curr_row_end pointers. - Change signatures of row processing methods of Rows_log_event and it descendants - now most arguments are taken from class members. - Remove do_prepare_row() methods which are no longer used. - The auto_afree_ptr template is moved to rpl_utility.h (so that it can be used in log_event_old.cc). - Removed copy_extra_fields() function - no longer used. In Rows_log_event::write_row (former replace_record): - The old code is moved to log_event_old.cc. - Use prepare_record() and non-destructive unpack_current_row() to fill record with data. - In case a record being inserted already exists on slave and row data is incomplete use the record found and non-destructive unpack_current_row() to combine new column values with existing ones. - More debug info added. In Rows_log_event::find_row (former find_and_fetch_row function): - The old code is moved to log_event_old.cc. - Unpacking of the row is moved here. - In case of search using PK, the key data is prepared here. - More debug info added. - Remove initialization of Rows_log_event::m_after_image buffer which is no longer used. - Use new row unpacking methods in Update_rows_log_event::do_exec_row() to create before and after image. Note: all existing code used by Rows_log_event::do_apply_event() has been moved to log_event_old.cc to be used by *_rows_log_event_old classes. sql/log_event.h: - Add new COMPLETE_ROWS_F flag in Rows_log_event. - Add Rows_log_event members describing the row being processed. - Add a pointer to key buffer which is used in derived classes. - Add new methods: find__row(), write_row() and unpack_current_row(). - Change signatures of do_...() methods (replace method arguments by class members). - Remove do_prepare_row() method which is no longer used. - Update method documentation. - Add Old_rows_log_event class, which contains the old row processing code, as a friend of Rows_log_event so that it can access all members of an event instance. sql/log_event_old.cc: Move here old implementation of Rows_log_event::do_apply_event() and helper methods. sql/log_event_old.h: - Define new class Old_rows_log_event encapsulating old version of Rows_log_event::do_apply_event() and the helper methods. - Add the Old_rows_log_event class as a base for *_old versions of RBR event classes, ensure that the old version of do_apply_event() is called. - For *_old classes, declare the helper methods used in the old version of do_apply_event(). sql/rpl_record.cc: - Make unpack_row non-destructive for columns not present in the row. - Don't fill read/write set here as it is done outside these functions. - Move initialization of a record with default values to a separate function prepare_record(). sql/rpl_record.h: - Change signature of unpack_row(). - Declare function prepare_record(). sql/rpl_utility.cc: Make tabe_def::calc_field_size() a const method. sql/rpl_utility.h: Make table_def::calc_field_size() a const method. Move auto_afree_ptr template here so that it can be re-used (currently in log_event.cc and log_event_old.cc). Similar with DBUG_PRINT_BITSET macro. mysql-test/extra/rpl_tests/rpl_ndb_2multi_basic.test: Modification of rpl_ndb_2multi_eng test. Tests with partitioned tables are removed and a setup with slave having different number of columns than master is added. mysql-test/include/rpl_multi_engine2.inc: Modification of rpl_multi_engine3.inc which operates on more rows and replaces "DELETE FROM t1" with "TRUNCATE TABLE t1" as the first form doesn't replicate in NDB -> non-NDB setting (BUG#28538). mysql-test/suite/rpl_ndb/r/rpl_ndb_2other.result: Results of the test. mysql-test/suite/rpl_ndb/t/rpl_ndb_2other-slave.opt: Test options. --log-slave-updates=0 is compulsory as otherwise non-NDB slave applying row events from NDB master will fail when trying to log them. mysql-test/suite/rpl_ndb/t/rpl_ndb_2other.test: Test replication of NDB table to slave using other engine. The main test is in extra/rpl_tests/rpl_ndb_2multi_basic.test. It is included here several times with different settings of default storage engine on slave.

Slave crashes during starting This patch has two purposes: (1) To refactor the code so that {Write|Update|Delete}_rows_log_event_old does not use code from {Write|Update|Delete}_rows_log_event. Before refactoring there was the following problem: whenever we modifed the code for new events, it affected the old events. This is bad, as it makes maintainance difficult. After refactoring, we can safely edit the new code without affecting old events. So, if we for instance modify the binary format of new events, we no longer need to worry about how the new code reads old events. (2) To fix BUG#31581. These two objectives are reached by the following changes: - Merged Rows_log_event into Old_rows_log_event and {Write|Update|Delete}_rows_log_event into {Write|Update|Delete}_rows_log_event_old. - Fixed the bug by replacing {WRITE|UPDATE|DELETE}_ROWS_EVENT by PRE_GA_{WRITE|UPDATE|DELETE}_ROWS_EVENT. - Added comments to log_event_old.h (This patch is identical to the previously committed patch which was a collapse of three changesets, except that it adds assert(0) to constructors for old types of row log events that should never be called.) sql/log_event_old.cc: Merged Rows_log_event into Old_rows_log_event and {Write|Update|Delete}_rows_log_event into {Write|Update|Delete}_rows_log_event_old. Also fixed the bug by replacing {WRITE|UPDATE|DELETE}_ROWS_EVENT by PRE_GA_{WRITE|UPDATE|DELETE}_ROWS_EVENT. sql/log_event_old.h: Merged Rows_log_event into Old_rows_log_event and {Write|Update|Delete}_rows_log_event into {Write|Update|Delete}_rows_log_event_old. Also added comment explaining what the file contains and what the classes do.

BUG#21842 (Cluster fails to replicate to innodb or myisam with err 134 using TPC-B): Problem: A RBR event can contain incomplete row data (only key value and fields which have been changed). In that case, when the row is unpacked into record and written to a table, the missing fields get incorrect NULL values leading to master-slave inconsistency. Solution: Use values found in slave's table for columns which are not given in the rows event. The code for writing a single row uses the following algorithm: 1. unpack row_data into table->record[0], 2. try to insert record, 3. if duplicate record found, fetch it into table->record[0], 4. unpack row_data into table->record[0], 5. write table->record[0] into the table. Where row_data is the row as stored in the data area of a rows event. Thus: a) unpacking of row_data happens at the time when row is written into a table, b) when unpacking (in step 4), only columns present in row_data are overwritten - all other columns remain as they were found in the table. Since all data needed for the above algorithm is stored inside Rows_log_event class, functions which locate and write rows are turned into methods of that class. replace_record() -> Rows_log_event::write_row() find_and_fetch_row() -> Rows_log_event::find_row() Both methods take row data from event's data buffer - the row being processed is pointed by m_curr_row. They unpack the data as needed into table's record buffers record[0] or record[1]. When row is unpacked, m_curr_row_end is set to point at next row in the data buffer. Other changes introduced in this changeset: - Change signature of unpack_row(): don't report errors and don't setup table's rw_set here. Errors can happen only when setting default values in prepare_record() function and are detected there. - In Rows_log_event and derived classes, don't pass arguments to the execution primitives (do_...() member functions) but use class members instead. - Move old row handling code into log_event_old.cc to be used by *_rows_log_event_old classes. Also, a new test rpl_ndb_2other is added which tests basic replication from master using ndb tables to slave storing the same tables using (possibly) different engine (myisam,innodb). Test is based on existing tests rpl_ndb_2myisam and rpl_ndb_2innodb. However, these tests doesn't work for various reasons and currently are disabled (see BUG#19227). The new test differs from the ones it is based on as follows: 1. Single test tests replication with different storage engines on slave (myisam, innodb, ndb). 2. Include file extra/rpl_tests/rpl_ndb_2multi_eng.test containing original tests is replaced by extra/rpl_tests/rpl_ndb_2multi_basic.test which doesn't contain tests using partitioned tables as these don't work currently. Instead, it tests replication to a slave which has more or less columns than master. 3. Include file include/rpl_multi_engine3.inc is replaced with include/rpl_multi_engine2.inc. The later differs by performing slightly different operations (updating more than one row in the table) and clearing table with "TRUNCATE TABLE" statement instead of "DELETE FROM" as replication of "DELETE" doesn't work well in this setting. 4. Slave must use option --log-slave-updates=0 as otherwise execution of replication events generated by ndb fails if table uses a different storage engine on slave (see BUG#29569). sql/log_event.cc: - Initialization of new Rows_log_event members. - Fixing some typos in documentation. In Rows_log_event::do_apply_event: - Set COMPLETE_ROWS_F flag (when master and slave have the same number of columns and all colums are present in the row) - Move initialization of tables write/read sets here, outside the rows processing loop (and out of unpack_row() function). - Remove calls to do_prepare_row() - no longer needed. - Add code managing m_curr_row and m_curr_row_end pointers. - Change signatures of row processing methods of Rows_log_event and it descendants - now most arguments are taken from class members. - Remove do_prepare_row() methods which are no longer used. - The auto_afree_ptr template is moved to rpl_utility.h (so that it can be used in log_event_old.cc). - Removed copy_extra_fields() function - no longer used. In Rows_log_event::write_row (former replace_record): - The old code is moved to log_event_old.cc. - Use prepare_record() and non-destructive unpack_current_row() to fill record with data. - In case a record being inserted already exists on slave and row data is incomplete use the record found and non-destructive unpack_current_row() to combine new column values with existing ones. - More debug info added. In Rows_log_event::find_row (former find_and_fetch_row function): - The old code is moved to log_event_old.cc. - Unpacking of the row is moved here. - In case of search using PK, the key data is prepared here. - More debug info added. - Remove initialization of Rows_log_event::m_after_image buffer which is no longer used. - Use new row unpacking methods in Update_rows_log_event::do_exec_row() to create before and after image. Note: all existing code used by Rows_log_event::do_apply_event() has been moved to log_event_old.cc to be used by *_rows_log_event_old classes. sql/log_event.h: - Add new COMPLETE_ROWS_F flag in Rows_log_event. - Add Rows_log_event members describing the row being processed. - Add a pointer to key buffer which is used in derived classes. - Add new methods: find__row(), write_row() and unpack_current_row(). - Change signatures of do_...() methods (replace method arguments by class members). - Remove do_prepare_row() method which is no longer used. - Update method documentation. - Add Old_rows_log_event class, which contains the old row processing code, as a friend of Rows_log_event so that it can access all members of an event instance. sql/log_event_old.cc: Move here old implementation of Rows_log_event::do_apply_event() and helper methods. sql/log_event_old.h: - Define new class Old_rows_log_event encapsulating old version of Rows_log_event::do_apply_event() and the helper methods. - Add the Old_rows_log_event class as a base for *_old versions of RBR event classes, ensure that the old version of do_apply_event() is called. - For *_old classes, declare the helper methods used in the old version of do_apply_event(). sql/rpl_record.cc: - Make unpack_row non-destructive for columns not present in the row. - Don't fill read/write set here as it is done outside these functions. - Move initialization of a record with default values to a separate function prepare_record(). sql/rpl_record.h: - Change signature of unpack_row(). - Declare function prepare_record(). sql/rpl_utility.cc: Make tabe_def::calc_field_size() a const method. sql/rpl_utility.h: Make table_def::calc_field_size() a const method. Move auto_afree_ptr template here so that it can be re-used (currently in log_event.cc and log_event_old.cc). Similar with DBUG_PRINT_BITSET macro. mysql-test/extra/rpl_tests/rpl_ndb_2multi_basic.test: Modification of rpl_ndb_2multi_eng test. Tests with partitioned tables are removed and a setup with slave having different number of columns than master is added. mysql-test/include/rpl_multi_engine2.inc: Modification of rpl_multi_engine3.inc which operates on more rows and replaces "DELETE FROM t1" with "TRUNCATE TABLE t1" as the first form doesn't replicate in NDB -> non-NDB setting (BUG#28538). mysql-test/suite/rpl_ndb/r/rpl_ndb_2other.result: Results of the test. mysql-test/suite/rpl_ndb/t/rpl_ndb_2other-slave.opt: Test options. --log-slave-updates=0 is compulsory as otherwise non-NDB slave applying row events from NDB master will fail when trying to log them. mysql-test/suite/rpl_ndb/t/rpl_ndb_2other.test: Test replication of NDB table to slave using other engine. The main test is in extra/rpl_tests/rpl_ndb_2multi_basic.test. It is included here several times with different settings of default storage engine on slave.

WL#3817: Simplify string / memory area types and make things more consistent (first part) The following type conversions was done: - Changed byte to uchar - Changed gptr to uchar* - Change my_string to char * - Change my_size_t to size_t - Change size_s to size_t Removed declaration of byte, gptr, my_string, my_size_t and size_s. Following function parameter changes was done: - All string functions in mysys/strings was changed to use size_t instead of uint for string lengths. - All read()/write() functions changed to use size_t (including vio). - All protocoll functions changed to use size_t instead of uint - Functions that used a pointer to a string length was changed to use size_t* - Changed malloc(), free() and related functions from using gptr to use void * as this requires fewer casts in the code and is more in line with how the standard functions work. - Added extra length argument to dirname_part() to return the length of the created string. - Changed (at least) following functions to take uchar* as argument: - db_dump() - my_net_write() - net_write_command() - net_store_data() - DBUG_DUMP() - decimal2bin() & bin2decimal() - Changed my_compress() and my_uncompress() to use size_t. Changed one argument to my_uncompress() from a pointer to a value as we only return one value (makes function easier to use). - Changed type of 'pack_data' argument to packfrm() to avoid casts. - Changed in readfrm() and writefrom(), ha_discover and handler::discover() the type for argument 'frmdata' to uchar** to avoid casts. - Changed most Field functions to use uchar* instead of char* (reduced a lot of casts). - Changed field->val_xxx(xxx, new_ptr) to take const pointers. Other changes: - Removed a lot of not needed casts - Added a few new cast required by other changes - Added some cast to my_multi_malloc() arguments for safety (as string lengths needs to be uint, not size_t). - Fixed all calls to hash-get-key functions to use size_t*. (Needed to be done explicitely as this conflict was often hided by casting the function to hash_get_key). - Changed some buffers to memory regions to uchar* to avoid casts. - Changed some string lengths from uint to size_t. - Changed field->ptr to be uchar* instead of char*. This allowed us to get rid of a lot of casts. - Some changes from true -> TRUE, false -> FALSE, unsigned char -> uchar - Include zlib.h in some files as we needed declaration of crc32() - Changed MY_FILE_ERROR to be (size_t) -1. - Changed many variables to hold the result of my_read() / my_write() to be size_t. This was needed to properly detect errors (which are returned as (size_t) -1). - Removed some very old VMS code - Changed packfrm()/unpackfrm() to not be depending on uint size (portability fix) - Removed windows specific code to restore cursor position as this causes slowdown on windows and we should not mix read() and pread() calls anyway as this is not thread safe. Updated function comment to reflect this. Changed function that depended on original behavior of my_pwrite() to itself restore the cursor position (one such case). - Added some missing checking of return value of malloc(). - Changed definition of MOD_PAD_CHAR_TO_FULL_LENGTH to avoid 'long' overflow. - Changed type of table_def::m_size from my_size_t to ulong to reflect that m_size is the number of elements in the array, not a string/memory length. - Moved THD::max_row_length() to table.cc (as it's not depending on THD). Inlined max_row_length_blob() into this function. - More function comments - Fixed some compiler warnings when compiled without partitions. - Removed setting of LEX_STRING() arguments in declaration (portability fix). - Some trivial indentation/variable name changes. - Some trivial code simplifications: - Replaced some calls to alloc_root + memcpy to use strmake_root()/strdup_root(). - Changed some calls from memdup() to strmake() (Safety fix) - Simpler loops in client-simple.c BitKeeper/etc/ignore: added libmysqld/ha_ndbcluster_cond.cc --- added debian/defs.mk debian/control

BUG#31581: 5.1-telco-6.1 -> 5.1.22. Slave crashes during starting This patch has two purposes: (1) To refactor the code so that {Write|Update|Delete}_rows_log_event_old does not use code from {Write|Update|Delete}_rows_log_event. Before refactoring there was the following problem: whenever we modifed the code for new events, it affected the old events. This is bad, as it makes maintainance difficult. After refactoring, we can safely edit the new code without affecting old events. So, if we for instance modify the binary format of new events, we no longer need to worry about how the new code reads old events. (2) To fix BUG#31581. These two objectives are reached by the following changes: - Merged Rows_log_event into Old_rows_log_event and {Write|Update|Delete}_rows_log_event into {Write|Update|Delete}_rows_log_event_old. - Fixed the bug by replacing {WRITE|UPDATE|DELETE}_ROWS_EVENT by PRE_GA_{WRITE|UPDATE|DELETE}_ROWS_EVENT. - Added comments to log_event_old.h (This patch is identical to the previously committed patch which was a collapse of three changesets, except that it adds assert(0) to constructors for old types of row log events that should never be called.) sql/log_event_old.cc: Merged Rows_log_event into Old_rows_log_event and {Write|Update|Delete}_rows_log_event into {Write|Update|Delete}_rows_log_event_old. Also fixed the bug by replacing {WRITE|UPDATE|DELETE}_ROWS_EVENT by PRE_GA_{WRITE|UPDATE|DELETE}_ROWS_EVENT. sql/log_event_old.h: Merged Rows_log_event into Old_rows_log_event and {Write|Update|Delete}_rows_log_event into {Write|Update|Delete}_rows_log_event_old. Also added comment explaining what the file contains and what the classes do.

BUG#21842 (Cluster fails to replicate to innodb or myisam with err 134 using TPC-B): Problem: A RBR event can contain incomplete row data (only key value and fields which have been changed). In that case, when the row is unpacked into record and written to a table, the missing fields get incorrect NULL values leading to master-slave inconsistency. Solution: Use values found in slave's table for columns which are not given in the rows event. The code for writing a single row uses the following algorithm: 1. unpack row_data into table->record[0], 2. try to insert record, 3. if duplicate record found, fetch it into table->record[0], 4. unpack row_data into table->record[0], 5. write table->record[0] into the table. Where row_data is the row as stored in the data area of a rows event. Thus: a) unpacking of row_data happens at the time when row is written into a table, b) when unpacking (in step 4), only columns present in row_data are overwritten - all other columns remain as they were found in the table. Since all data needed for the above algorithm is stored inside Rows_log_event class, functions which locate and write rows are turned into methods of that class. replace_record() -> Rows_log_event::write_row() find_and_fetch_row() -> Rows_log_event::find_row() Both methods take row data from event's data buffer - the row being processed is pointed by m_curr_row. They unpack the data as needed into table's record buffers record[0] or record[1]. When row is unpacked, m_curr_row_end is set to point at next row in the data buffer. Other changes introduced in this changeset: - Change signature of unpack_row(): don't report errors and don't setup table's rw_set here. Errors can happen only when setting default values in prepare_record() function and are detected there. - In Rows_log_event and derived classes, don't pass arguments to the execution primitives (do_...() member functions) but use class members instead. - Move old row handling code into log_event_old.cc to be used by *_rows_log_event_old classes. Also, a new test rpl_ndb_2other is added which tests basic replication from master using ndb tables to slave storing the same tables using (possibly) different engine (myisam,innodb). Test is based on existing tests rpl_ndb_2myisam and rpl_ndb_2innodb. However, these tests doesn't work for various reasons and currently are disabled (see BUG#19227). The new test differs from the ones it is based on as follows: 1. Single test tests replication with different storage engines on slave (myisam, innodb, ndb). 2. Include file extra/rpl_tests/rpl_ndb_2multi_eng.test containing original tests is replaced by extra/rpl_tests/rpl_ndb_2multi_basic.test which doesn't contain tests using partitioned tables as these don't work currently. Instead, it tests replication to a slave which has more or less columns than master. 3. Include file include/rpl_multi_engine3.inc is replaced with include/rpl_multi_engine2.inc.

BUG#31581: 5.1-telco-6.1 -> 5.1.22. Slave crashes during starting This patch has two purposes: (1) To refactor the code so that {Write|Update|Delete}_rows_log_event_old does not use code from {Write|Update|Delete}_rows_log_event. Before refactoring there was the following problem: whenever we modifed the code for new events, it affected the old events. This is bad, as it makes maintainance difficult. After refactoring, we can safely edit the new code without affecting old events. So, if we for instance modify the binary format of new events, we no longer need to worry about how the new code reads old events. (2) To fix BUG#31581. These two objectives are reached by the following changes: - Merged Rows_log_event into Old_rows_log_event and {Write|Update|Delete}_rows_log_event into {Write|Update|Delete}_rows_log_event_old. - Fixed the bug by replacing {WRITE|UPDATE|DELETE}_ROWS_EVENT by PRE_GA_{WRITE|UPDATE|DELETE}_ROWS_EVENT. - Added comments to log_event_old.h (This patch is identical to the previously committed patch which was a collapse of three changesets, except that it adds assert(0) to constructors for old types of row log events that should never be called.) sql/log_event_old.cc: Merged Rows_log_event into Old_rows_log_event and {Write|Update|Delete}_rows_log_event into {Write|Update|Delete}_rows_log_event_old. Also fixed the bug by replacing {WRITE|UPDATE|DELETE}_ROWS_EVENT by PRE_GA_{WRITE|UPDATE|DELETE}_ROWS_EVENT. sql/log_event_old.h: Merged Rows_log_event into Old_rows_log_event and {Write|Update|Delete}_rows_log_event into {Write|Update|Delete}_rows_log_event_old.

BUG#21842 (Cluster fails to replicate to innodb or myisam with err 134 using TPC-B): Problem: A RBR event can contain incomplete row data (only key value and fields which have been changed). In that case, when the row is unpacked into record and written to a table, the missing fields get incorrect NULL values leading to master-slave inconsistency. Solution: Use values found in slave's table for columns which are not given in the rows event. The code for writing a single row uses the following algorithm: 1. unpack row_data into table->record[0], 2. try to insert record, 3. if duplicate record found, fetch it into table->record[0], 4. unpack row_data into table->record[0], 5. write table->record[0] into the table. Where row_data is the row as stored in the data area of a rows event. Thus: a) unpacking of row_data happens at the time when row is written into a table, b) when unpacking (in step 4), only columns present in row_data are overwritten - all other columns remain as they were found in the table. Since all data needed for the above algorithm is stored inside Rows_log_event class, functions which locate and write rows are turned into methods of that class. replace_record() -> Rows_log_event::write_row() find_and_fetch_row() -> Rows_log_event::find_row() Both methods take row data from event's data buffer - the row being processed is pointed by m_curr_row. They unpack the data as needed into table's record buffers record[0] or record[1]. When row is unpacked, m_curr_row_end is set to point at next row in the data buffer. Other changes introduced in this changeset: - Change signature of unpack_row(): don't report errors and don't setup table's rw_set here. Errors can happen only when setting default values in prepare_record() function and are detected there. - In Rows_log_event and derived classes, don't pass arguments to the execution primitives (do_...() member functions) but use class members instead. - Move old row handling code into log_event_old.cc to be used by *_rows_log_event_old classes. Also, a new test rpl_ndb_2other is added which tests basic replication from master using ndb tables to slave storing the same tables using (possibly) different engine (myisam,innodb). Test is based on existing tests rpl_ndb_2myisam and rpl_ndb_2innodb. However, these tests doesn't work for various reasons and currently are disabled (see BUG#19227). The new test differs from the ones it is based on as follows: 1. Single test tests replication with different storage engines on slave (myisam, innodb, ndb). 2. Include file extra/rpl_tests/rpl_ndb_2multi_eng.test containing original tests is replaced by extra/rpl_tests/rpl_ndb_2multi_basic.test which doesn't contain tests using partitioned tables as these don't work currently. Instead, it tests replication to a slave which has more or less columns than master. 3. Include file include/rpl_multi_engine3.inc is replaced with include/rpl_multi_engine2.inc. The later differs by performing slightly different operations (updating more than one row in the table) and clearing table with "TRUNCATE TABLE" statement instead of "DELETE FROM" as replication of "DELETE" doesn't work well in this setting. 4.

Fixed a lot of compiler warnings and errors detected by Forte C++ on Solaris Faster thr_alarm() Added 'Opened_files' status variable to track calls to my_open() Don't give warnings when running mysql_install_db Added option --source-install to mysql_install_db I had to do the following renames() as used polymorphism didn't work with Forte compiler on 64 bit systems index_read() -> index_read_map() index_read_idx() -> index_read_idx_map() index_read_last() -> index_read_last_map() BUILD/compile-solaris-sparc-forte: Updated script to current Solaris installations Now we compile by default for 64 bits client/mysql.cc: Declare functions sent to C code with extern "C" to avoid compiler warnings (on Forte) client/mysql_upgrade.c: Fixed compiler warning (on Forte) client/mysqladmin.cc: Declare functions sent to C code with extern "C" to avoid compiler warnings (on Forte) client/mysqlcheck.c: Fixed compiler warning (on Forte) client/mysqldump.c: Fixed compiler warning (on Forte) client/mysqlslap.c: Fixed compiler warning (on Forte) client/mysqltest.c: Fixed compiler warning (on Forte) client/sql_string.cc: Avoid compiler warnings when using C function pointers in C++ configure.in: Added detection of mtmalloc and ieeefp.h extra/replace.c: Fixed compiler warning (on Forte) include/m_ctype.h: Added some typedef's to make it easy to use C function pointers in C++ include/my_sys.h: Added my_file_total_opened (counter for calls to my_open()) include/myisam.h: Fixed compiler warning (on Forte) libmysql/libmysql.c: Fixed compiler warning (on Forte) by adding casts and change types libmysql/manager.c: Fixed compiler warning (on Forte) by adding casts and change types mysql-test/r/ctype_cp932_binlog_stm.result: Updated positions (Needed because we didn't before correctly restore collation_database after running stored procedure mysys/my_fopen.c: Count number of opened files mysys/my_open.c: Count number of opened files mysys/my_static.c: Count number of opened files mysys/thr_alarm.c: Optimization to do less alarm() and pthread_sigmask() calls. Idea is to remember time for next pending alarm and not reschedule a new alarm if it's after the current one. Before we only did this if there was other pending alarms. We don't have to use pthread_sigmask() in case of 'USE_ONE_SIGNAL_HAND' as the alarm() signal will be blocked for the calling thread anyway and no other thread will have the alarm() signal enabled to call process_alarm() regex/regcomp.c: Fixed compiler warning (on Forte) by adding casts and change types scripts/mysql_install_db.sh: Added option --source-install to allow one to create a mysql database from the source tree without installing MySQL Don't give (unnecessary) warnings server-tools/instance-manager/angel.cc: Declare functions sent to C code with extern "C" to avoid compiler warnings (on Forte) server-tools/instance-manager/thread_registry.cc: Declare functions sent to C code with extern "C" to avoid compiler warnings (on Forte) sql/event_db_repository.cc: index_read() -> index_read_map() sql/event_queue.cc: Declare functions sent to C code with extern "C" to avoid compiler warnings (on Forte) sql/field.cc: Fixed compiler warnings about hidden fields sql/ha_partition.cc: Fixed compiler warnings about hidden fields index_read() -> index_read_map() sql/ha_partition.h: index_read() -> index_read_map() sql/handler.cc: Added PAGE option to row types (to prepare for future) index_read() -> index_read_map() sql/handler.h: Added ROW_TYPE_PAGE (for future) Added flag to signal if table was to be created transactionally I had to do the following renames() as used polymorphism didn't work with Forte compiler on 64 bit systems index_read() -> index_read_map() index_read_idx() -> index_read_idx_map() index_read_last() -> index_read_last_map() sql/item.cc: Fixed indentation Renamed local variable to avoid hiding class variable sql/item_cmpfunc.cc: Renamed local variable to avoid hiding class variable sql/item_cmpfunc.h: Removed not used variable sql/item_func.cc: Renamed local variable to avoid hiding class variable sql/item_strfunc.cc: Moved functions from Item_strfunc.cc sql/item_strfunc.h: Move functions to item_strfunc.cc Use C function pointer type to avoid compiler warnings (with Forte) sql/item_subselect.cc: index_read() -> index_read_map() sql/item_xmlfunc.cc: Renamed local variable to avoid hiding class variable Declare functions sent to C code with extern "C" to avoid compiler warnings (on Forte) sql/key.cc: Fixed indentation sql/log.cc: Renamed local variable to avoid hiding class variable sql/log_event.cc: Removed call to my_time() when creating class instance of Log_event() as this may have static instances.

indentation Don't call end_thr_alarm() when calling unireg_abort() as unireg_abort() already calls end_thr_alarm() Added variable 'Opened_files' (number of calls to my_open() or my_fopen()) Don't print 'loose' warnings when using --bootstrap (to avoid warnings when running mysql_install_db) Fixed compiler warnings sql/opt_range.cc: index_read() -> index_read_map() sql/opt_sum.cc: index_read()

WL#3817: Simplify string / memory area types and make things more consistent (first part) The following type conversions was done: - Changed byte to uchar - Changed gptr to uchar* - Change my_string to char * - Change my_size_t to size_t - Change size_s to size_t Removed declaration of byte, gptr, my_string, my_size_t and size_s. Following function parameter changes was done: - All string functions in mysys/strings was changed to use size_t instead of uint for string lengths. - All read()/write() functions changed to use size_t (including vio). - All protocoll functions changed to use size_t instead of uint - Functions that used a pointer to a string length was changed to use size_t* - Changed malloc(), free() and related functions from using gptr to use void * as this requires fewer casts in the code and is more in line with how the standard functions work. - Added extra length argument to dirname_part() to return the length of the created string. - Changed (at least) following functions to take uchar* as argument: - db_dump() - my_net_write() - net_write_command() - net_store_data() - DBUG_DUMP() - decimal2bin() & bin2decimal() - Changed my_compress() and my_uncompress() to use size_t. Changed one argument to my_uncompress() from a pointer to a value as we only return one value (makes function easier to use). - Changed type of 'pack_data' argument to packfrm() to avoid casts. - Changed in readfrm() and writefrom(), ha_discover and handler::discover() the type for argument 'frmdata' to uchar** to avoid casts. - Changed most Field functions to use uchar* instead of char* (reduced a lot of casts). - Changed field->val_xxx(xxx, new_ptr) to take const pointers. Other changes: - Removed a lot of not needed casts - Added a few new cast required by other changes - Added some cast to my_multi_malloc() arguments for safety (as string lengths needs to be uint, not size_t). - Fixed all calls to hash-get-key functions to use size_t*. (Needed to be done explicitely as this conflict was often hided by casting the function to hash_get_key). - Changed some buffers to memory regions to uchar* to avoid casts. - Changed some string lengths from uint to size_t. - Changed field->ptr to be uchar* instead of char*. This allowed us to get rid of a lot of casts. - Some changes from true -> TRUE, false -> FALSE, unsigned char -> uchar - Include zlib.h in some files as we needed declaration of crc32() - Changed MY_FILE_ERROR to be (size_t) -1. - Changed many variables to hold the result of my_read() / my_write() to be size_t. This was needed to properly detect errors (which are returned as (size_t) -1). - Removed some very old VMS code - Changed packfrm()/unpackfrm() to not be depending on uint size (portability fix) - Removed windows specific code to restore cursor position as this causes slowdown on windows and we should not mix read() and pread() calls anyway as this is not thread safe. Updated function comment to reflect this. Changed function that depended on original behavior of my_pwrite() to itself restore the cursor position (one such case). - Added some missing checking of return value of malloc(). - Changed definition of MOD_PAD_CHAR_TO_FULL_LENGTH to avoid 'long' overflow. - Changed type of table_def::m_size from my_size_t to ulong to reflect that m_size is the number of elements in the array, not a string/memory length. - Moved THD::max_row_length() to table.cc (as it's not depending on THD). Inlined max_row_length_blob() into this function. - More function comments - Fixed some compiler warnings when compiled without partitions. - Removed setting of LEX_STRING() arguments in declaration (portability fix). - Some trivial indentation/variable name changes. - Some trivial code simplifications: - Replaced some calls to alloc_root + memcpy to use strmake_root()/strdup_root(). - Changed some calls from memdup() to strmake() (Safety fix) - Simpler loops in client-simple.c BitKeeper/etc/ignore: added libmysqld/ha_ndbcluster_cond.cc --- added debian/defs.mk debian/control

WL#3817: Simplify string / memory area types and make things more consistent (first part) The following type conversions was done: - Changed byte to uchar - Changed gptr to uchar* - Change my_string to char * - Change my_size_t to size_t - Change size_s to size_t Removed declaration of byte, gptr, my_string, my_size_t and size_s. Following function parameter changes was done: - All string functions in mysys/strings was changed to use size_t instead of uint for string lengths. - All read()/write() functions changed to use size_t (including vio). - All protocoll functions changed to use size_t instead of uint - Functions that used a pointer to a string length was changed to use size_t* - Changed malloc(), free() and related functions from using gptr to use void * as this requires fewer casts in the code and is more in line with how the standard functions work. - Added extra length argument to dirname_part() to return the length of the created string. - Changed (at least) following functions to take uchar* as argument: - db_dump() - my_net_write() - net_write_command() - net_store_data() - DBUG_DUMP() - decimal2bin() & bin2decimal() - Changed my_compress() and my_uncompress() to use size_t. Changed one argument to my_uncompress() from a pointer to a value as we only return one value (makes function easier to use). - Changed type of 'pack_data' argument to packfrm() to avoid casts. - Changed in readfrm() and writefrom(), ha_discover and handler::discover() the type for argument 'frmdata' to uchar** to avoid casts. - Changed most Field functions to use uchar* instead of char* (reduced a lot of casts). - Changed field->val_xxx(xxx, new_ptr) to take const pointers. Other changes: - Removed a lot of not needed casts - Added a few new cast required by other changes - Added some cast to my_multi_malloc() arguments for safety (as string lengths needs to be uint, not size_t). - Fixed all calls to hash-get-key functions to use size_t*. (Needed to be done explicitely as this conflict was often hided by casting the function to hash_get_key). - Changed some buffers to memory regions to uchar* to avoid casts. - Changed some string lengths from uint to size_t. - Changed field->ptr to be uchar* instead of char*. This allowed us to get rid of a lot of casts. - Some changes from true -> TRUE, false -> FALSE, unsigned char -> uchar - Include zlib.h in some files as we needed declaration of crc32() - Changed MY_FILE_ERROR to be (size_t) -1. - Changed many variables to hold the result of my_read() / my_write() to be size_t. This was needed to properly detect errors (which are returned as (size_t) -1). - Removed some very old VMS code - Changed packfrm()/unpackfrm() to not be depending on uint size (portability fix) - Removed windows specific code to restore cursor position as this causes slowdown on windows and we should not mix read() and pread() calls anyway as this is not thread safe. Updated function comment to reflect this. Changed function that depended on original behavior of my_pwrite() to itself restore the cursor position (one such case). - Added some missing checking of return value of malloc(). - Changed definition of MOD_PAD_CHAR_TO_FULL_LENGTH to avoid 'long' overflow. - Changed type of table_def::m_size from my_size_t to ulong to reflect that m_size is the number of elements in the array, not a string/memory length. - Moved THD::max_row_length() to table.cc (as it's not depending on THD). Inlined max_row_length_blob() into this function. - More function comments - Fixed some compiler warnings when compiled without partitions. - Removed setting of LEX_STRING() arguments in declaration (portability fix). - Some trivial indentation/variable name changes. - Some trivial code simplifications: - Replaced some calls to alloc_root + memcpy to use strmake_root()/strdup_root(). - Changed some calls from memdup() to strmake() (Safety fix) - Simpler loops in client-simple.c BitKeeper/etc/ignore: added libmysqld/ha_ndbcluster_cond.cc --- added debian/defs.mk debian/control

BUG#31581: 5.1-telco-6.1 -> 5.1.22. Slave crashes during starting This patch has two purposes: (1) To refactor the code so that {Write|Update|Delete}_rows_log_event_old does not use code from {Write|Update|Delete}_rows_log_event. Before refactoring there was the following problem: whenever we modifed the code for new events, it affected the old events. This is bad, as it makes maintainance difficult. After refactoring, we can safely edit the new code without affecting old events. So, if we for instance modify the binary format of new events, we no longer need to worry about how the new code reads old events. (2) To fix BUG#31581. These two objectives are reached by the following changes: - Merged Rows_log_event into Old_rows_log_event and {Write|Update|Delete}_rows_log_event into {Write|Update|Delete}_rows_log_event_old. - Fixed the bug by replacing {WRITE|UPDATE|DELETE}_ROWS_EVENT by PRE_GA_{WRITE|UPDATE|DELETE}_ROWS_EVENT. - Added comments to log_event_old.h (This patch is identical to the previously committed patch which was a collapse of three changesets, except that it adds assert(0) to constructors for old types of row log events that should never be called.) sql/log_event_old.cc: Merged Rows_log_event into Old_rows_log_event and {Write|Update|Delete}_rows_log_event into {Write|Update|Delete}_rows_log_event_old. Also fixed the bug by replacing {WRITE|UPDATE|DELETE}_ROWS_EVENT by PRE_GA_{WRITE|UPDATE|DELETE}_ROWS_EVENT. sql/log_event_old.h: Merged Rows_log_event into Old_rows_log_event and {Write|Update|Delete}_rows_log_event into {Write|Update|Delete}_rows_log_event_old. Also added comment explaining what the file contains and what the classes do.

BUG#21842 (Cluster fails to replicate to innodb or myisam with err 134 using TPC-B): Problem: A RBR event can contain incomplete row data (only key value and fields which have been changed). In that case, when the row is unpacked into record and written to a table, the missing fields get incorrect NULL values leading to master-slave inconsistency. Solution: Use values found in slave's table for columns which are not given in the rows event. The code for writing a single row uses the following algorithm: 1. unpack row_data into table->record[0], 2. try to insert record, 3. if duplicate record found, fetch it into table->record[0], 4. unpack row_data into table->record[0], 5. write table->record[0] into the table. Where row_data is the row as stored in the data area of a rows event. Thus: a) unpacking of row_data happens at the time when row is written into a table, b) when unpacking (in step 4), only columns present in row_data are overwritten - all other columns remain as they were found in the table. Since all data needed for the above algorithm is stored inside Rows_log_event class, functions which locate and write rows are turned into methods of that class. replace_record() -> Rows_log_event::write_row() find_and_fetch_row() -> Rows_log_event::find_row() Both methods take row data from event's data buffer - the row being processed is pointed by m_curr_row. They unpack the data as needed into table's record buffers record[0] or record[1]. When row is unpacked, m_curr_row_end is set to point at next row in the data buffer. Other changes introduced in this changeset: - Change signature of unpack_row(): don't report errors and don't setup table's rw_set here. Errors can happen only when setting default values in prepare_record() function and are detected there. - In Rows_log_event and derived classes, don't pass arguments to the execution primitives (do_...() member functions) but use class members instead. - Move old row handling code into log_event_old.cc to be used by *_rows_log_event_old classes. Also, a new test rpl_ndb_2other is added which tests basic replication from master using ndb tables to slave storing the same tables using (possibly) different engine (myisam,innodb). Test is based on existing tests rpl_ndb_2myisam and rpl_ndb_2innodb. However, these tests doesn't work for various reasons and currently are disabled (see BUG#19227). The new test differs from the ones it is based on as follows: 1. Single test tests replication with different storage engines on slave (myisam, innodb, ndb). 2. Include file extra/rpl_tests/rpl_ndb_2multi_eng.test containing original tests is replaced by extra/rpl_tests/rpl_ndb_2multi_basic.test which doesn't contain tests using partitioned tables as these don't work currently. Instead, it tests replication to a slave which has more or less columns than master. 3. Include file include/rpl_multi_engine3.inc is replaced with include/rpl_multi_engine2.inc. The later differs by performing slightly different operations (updating more than one row in the table) and clearing table with "TRUNCATE TABLE" statement instead of "DELETE FROM" as replication of "DELETE" doesn't work well in this setting. 4. Slave must use option --log-slave-updates=0 as otherwise execution of replication events generated by ndb fails if table uses a different storage engine on slave (see BUG#29569). sql/log_event.cc: - Initialization of new Rows_log_event members. - Fixing some typos in documentation. In Rows_log_event::do_apply_event: - Set COMPLETE_ROWS_F flag (when master and slave have the same number of columns and all colums are present in the row) - Move initialization of tables write/read sets here, outside the rows processing loop (and out of unpack_row() function). - Remove calls to do_prepare_row() - no longer needed. - Add code managing m_curr_row and m_curr_row_end pointers. - Change signatures of row processing methods of Rows_log_event and it descendants - now most arguments are taken from class members. - Remove do_prepare_row() methods which are no longer used. - The auto_afree_ptr template is moved to rpl_utility.h (so that it can be used in log_event_old.cc). - Removed copy_extra_fields() function - no longer used. In Rows_log_event::write_row (former replace_record): - The old code is moved to log_event_old.cc. - Use prepare_record() and non-destructive unpack_current_row() to fill record with data. - In case a record being inserted already exists on slave and row data is incomplete use the record found and non-destructive unpack_current_row() to combine new column values with existing ones. - More debug info added. In Rows_log_event::find_row (former find_and_fetch_row function): - The old code is moved to log_event_old.cc. - Unpacking of the row is moved here. - In case of search using PK, the key data is prepared here. - More debug info added. - Remove initialization of Rows_log_event::m_after_image buffer which is no longer used. - Use new row unpacking methods in Update_rows_log_event::do_exec_row() to create before and after image. Note: all existing code used by Rows_log_event::do_apply_event() has been moved to log_event_old.cc to be used by *_rows_log_event_old classes. sql/log_event.h: - Add new COMPLETE_ROWS_F flag in Rows_log_event. - Add Rows_log_event members describing the row being processed. - Add a pointer to key buffer which is used in derived classes. - Add new methods: find__row(), write_row() and unpack_current_row(). - Change signatures of do_...() methods (replace method arguments by class members). - Remove do_prepare_row() method which is no longer used. - Update method documentation. - Add Old_rows_log_event class, which contains the old row processing code, as a friend of Rows_log_event so that it can access all members of an event instance. sql/log_event_old.cc: Move here old implementation of Rows_log_event::do_apply_event() and helper methods. sql/log_event_old.h: - Define new class Old_rows_log_event encapsulating old version of Rows_log_event::do_apply_event() and the helper methods. - Add the Old_rows_log_event class as a base for *_old versions of RBR event classes, ensure that the old version of do_apply_event() is called. - For *_old classes, declare the helper methods used in the old version of do_apply_event(). sql/rpl_record.cc: - Make unpack_row non-destructive for columns not present in the row. - Don't fill read/write set here as it is done outside these functions. - Move initialization of a record with default values to a separate function prepare_record(). sql/rpl_record.h: - Change signature of unpack_row(). - Declare function prepare_record(). sql/rpl_utility.cc: Make tabe_def::calc_field_size() a const method. sql/rpl_utility.h: Make table_def::calc_field_size() a const method. Move auto_afree_ptr template here so that it can be re-used (currently in log_event.cc and log_event_old.cc). Similar with DBUG_PRINT_BITSET macro. mysql-test/extra/rpl_tests/rpl_ndb_2multi_basic.test: Modification of rpl_ndb_2multi_eng test. Tests with partitioned tables are removed and a setup with slave having different number of columns than master is added. mysql-test/include/rpl_multi_engine2.inc: Modification of rpl_multi_engine3.inc which operates on more rows and replaces "DELETE FROM t1" with "TRUNCATE TABLE t1" as the first form doesn't replicate in NDB -> non-NDB setting (BUG#28538). mysql-test/suite/rpl_ndb/r/rpl_ndb_2other.result: Results of the test. mysql-test/suite/rpl_ndb/t/rpl_ndb_2other-slave.opt: Test options. --log-slave-updates=0 is compulsory as otherwise non-NDB slave applying row events from NDB master will fail when trying to log them. mysql-test/suite/rpl_ndb/t/rpl_ndb_2other.test: Test replication of NDB table to slave using other engine. The main test is in extra/rpl_tests/rpl_ndb_2multi_basic.test. It is included here several times with different settings of default storage engine on slave.

BUG#31581: 5.1-telco-6.1 -> 5.1.22.

Before refactoring there was the following problem: whenever we modifed the code for new events, it affected the old events. This is bad, as it makes maintainance difficult.

Write the current row into event's table.
The row is located in the row buffer, pointed by @c m_curr_row member.
Number of columns of the row is stored in @c m_width member (it can be
different from the number of columns in the table to which we insert).
Bitmap @c m_cols indicates which columns are present in the row. It is assumed
that event's table is already open and pointed by @c m_table.
If the same record already exists in the table it can be either overwritten
or an error is reported depending on the value of @c overwrite flag
(error reporting not yet implemented). Note that the matching record can be
different from the row we insert if we use primary keys to identify records in
the table.
The row to be inserted can contain values only for selected columns. The

Bug #32971 No user level error message from slave sql thread when ER_NO_DEFAULT_FOR_FIELD The error message due to lack of the default value for an extra field was not as informative as it should be. Fixed with improving the scheme of gathering, propagating and reporting errors in applying rows events. The scheme is in the following. Any kind of error of processing of a row event incidents are to be registered with my_error(). In the end Rows_log_event::do_apply_event() invokes rli->report() with the message to display consisting of all the errors. This mimics `show warnings' displaying. A simple test checks three errors in processing an event. Two hunks - a user level error and pushing it into the list - have been devoted to already fixed Bug@31702.

BUG#31581: 5.1-telco-6.1 -> 5.1.22. Slave crashes during starting This patch has two purposes: (1) To refactor the code so that {Write|Update|Delete}_rows_log_event_old does not use code from {Write|Update|Delete}_rows_log_event. Before refactoring there was the following problem: whenever we modifed the code for new events, it affected the old events. This is bad, as it makes maintainance difficult. After refactoring, we can safely edit the new code without affecting old events. So, if we for instance modify the binary format of new events, we no longer need to worry about how the new code reads old events. (2) To fix BUG#31581. These two objectives are reached by the following changes: - Merged Rows_log_event into Old_rows_log_event and {Write|Update|Delete}_rows_log_event into {Write|Update|Delete}_rows_log_event_old. - Fixed the bug by replacing {WRITE|UPDATE|DELETE}_ROWS_EVENT by PRE_GA_{WRITE|UPDATE|DELETE}_ROWS_EVENT. - Added comments to log_event_old.h (This patch is identical to the previously committed patch which was a collapse of three changesets, except that it adds assert(0) to constructors for old types of row log events that should never be called.) sql/log_event_old.cc: Merged Rows_log_event into Old_rows_log_event and {Write|Update|Delete}_rows_log_event into {Write|Update|Delete}_rows_log_event_old. Also fixed the bug by replacing {WRITE|UPDATE|DELETE}_ROWS_EVENT by PRE_GA_{WRITE|UPDATE|DELETE}_ROWS_EVENT. sql/log_event_old.h: Merged Rows_log_event into Old_rows_log_event and {Write|Update|Delete}_rows_log_event into {Write|Update|Delete}_rows_log_event_old.
