Normally, auto_increment value is generated for the column by inserting either NULL or 0 into it. NO_AUTO_VALUE_ON_ZERO suppresses this behavior for 0 so that only NULL generates the auto_increment value. This behavior is also followed by a slave, specifically by the SQL Thread, when applying events in the statement format from a master. However, when applying events in the row format, the flag was ignored thus causing an assertion failure: "Assertion failed: next_insert_id == 0, file .\handler.cc" In fact, we never need to generate a auto_increment value for the column when applying events in row format on slave. So we don't allow it to happen by using 'MODE_NO_AUTO_VALUE_ON_ZERO'. Refactoring: Get rid of all the sql_mode checks to rows_log_event when applying it for avoiding problems caused by the inconsistency of the sql_mode on slave and master as the sql_mode is not set for Rows_log_event. mysql-test/extra/rpl_tests/rpl_auto_increment.test: Added test to verify if the assertion of "next_insert_id == 0" will fail in ha_external_lock() function. mysql-test/suite/rpl/r/rpl_auto_increment.result: Test result for bug#56662. sql/log_event.cc: Added code to not allow generation of auto_increment value when processing rows event by adding 'MODE_NO_AUTO_VALUE_ON_ZERO' to sql_mode. sql/rpl_record.cc: Added code to get rid of the 'MODE_STRICT_TRANS_TABLES' and MODE_STRICT_ALL_TABLES check to the table when appling the rows event and treat it as no strict.
