WL#3023 (Use locks in a statement-like manner):
Table maps are now written on aquiring locks to tables and released at the end of each logical statement. mysql-test/extra/binlog_tests/ctype_cp932.test: Disabling cleanup code mysql-test/r/binlog_row_blackhole.result: Result change mysql-test/r/binlog_row_mix_innodb_myisam.result: Result change mysql-test/r/binlog_stm_ctype_cp932.result: Result change mysql-test/r/rpl_row_charset.result: Result change mysql-test/r/rpl_row_create_table.result: Result change mysql-test/t/rpl_row_create_table.test: Binlog position change sql/handler.cc: Writing table map after external_lock() sql/handler.h: Adding class for table operation hooks. sql/log.cc: Adding binlog_write_table_map() to THD. Removing write_table_map() from MYSQL_LOG. sql/log.h: Minor interface changes to move table map writing. sql/log_event.cc: Removing pre-allocation of memory for buffers. Allowing ULONG_MAX as table id denoting an event to ignore (only used to transfer flags). Adding code to collect tables while seeing table maps and lock collected tables when seeing a binrow event. Debriding code as a result of the above changes. sql/log_event.h: Minor interface changes. sql/mysql_priv.h: Adding hooks argument to create_table_from_items(). sql/parse_file.cc: Minor fix to avoid crash in debug printout. sql/rpl_rli.h: Adding list of tables to lock to RLI structure. sql/slave.cc: Using list of tables to lock from RLI structure. sql/sql_acl.cc: Removing redundant pending events flush. sql/sql_base.cc: Moving pending event flush. Using flag to guard to clear statement transaction only if this is the original open tables state. sql/sql_class.cc: Adding flag for open tables state. Removing redundant pending events flushes. Write a dummy event to indicate that the tables to lock should be emptied on the slave. sql/sql_class.h: Adding open tables state flags. Adding binlog_write_table_map() function to THD. Changes to select_create() to support new locking scheme. sql/sql_insert.cc: Adding rollback of statement transaction on error. It can now contain events after locking tables. sql/sql_load.cc: Removing redundant pending event flush. sql/sql_table.cc: Adding hooks argument to create_table_from_items(). Calling prelock hook before starting to lock tables. sql/sql_update.cc: Removing a compiler warning. sql/table.h: Minor changes.
