Bug#31552 Replication breaks when deleting rows from out-of-sync table
without PK Bug#31609 Not all RBR slave errors reported as errors bug#32468 delete rows event on a table with foreign key constraint fails The first two bugs comprise idempotency issues. First, there was no error code reported under conditions of the bug description although the slave sql thread halted. Second, executions were different with and without presence of prim key in the table. Third, there was no way to instruct the slave whether to ignore an error and skip to the following event or to halt. Fourth, there are handler errors which might happen due to idempotent applying of binlog but those were not listed among the "idempotent" error list. All the named issues are addressed. Wrt to the 3rd, there is the new global system variable, changeble at run time, which controls the slave sql thread behaviour. The new variable allows further extensions to mimic the sql_mode session/global variable. To address the 4th, the new bug#32468 had to be fixed as it was staying in the way. include/my_bitmap.h: basic operations with bits of an integer type are added. mysql-test/extra/rpl_tests/rpl_foreign_key.test: regression test for bug#32468 mysql-test/extra/rpl_tests/rpl_row_basic.test: changes due to bug#31552/31609 idempotency is not default any longer mysql-test/extra/rpl_tests/rpl_row_tabledefs.test: changes due to bug#31552/31609 idempotency is not default any longer mysql-test/suite/rpl/r/rpl_foreign_key_innodb.result: results changed mysql-test/suite/rpl/r/rpl_idempotency.result: results changed mysql-test/suite/rpl/r/rpl_row_basic_11bugs.result: results changed mysql-test/suite/rpl/r/rpl_row_basic_2myisam.result: results changed mysql-test/suite/rpl/r/rpl_row_basic_3innodb.result: results changed mysql-test/suite/rpl/r/rpl_row_mystery22.result: results changed mysql-test/suite/rpl/r/rpl_row_tabledefs_2myisam.result: results changed mysql-test/suite/rpl/r/rpl_row_tabledefs_3innodb.result: results changed mysql-test/suite/rpl/r/rpl_temporary_errors.result: results changed mysql-test/suite/rpl/t/rpl_idempotency.test: extenstions to the test providing testing of complements to the idempotent error set and checking how slave halts when it faces an error from the list when the mode is STRICT. mysql-test/suite/rpl/t/rpl_row_basic_11bugs.test: changes due to bug#31552/31609 idempotency is not default any longer. mysql-test/suite/rpl/t/rpl_row_mystery22.test: changes due to bug#31552/31609 idempotency is not default any longer mysql-test/suite/rpl/t/rpl_temporary_errors.test: changes due to bug#31552/31609 idempotency is not default any longer mysql-test/suite/rpl_ndb/r/rpl_ndb_dd_advance.result: results changed mysql-test/suite/rpl_ndb/r/rpl_row_basic_7ndb.result: results changed sql/log_event.cc: the fix for bug#32468 delete rows event on a table with foreign key constraint fails ensures the flags are set at proper time so that their values will be caught by innodb. reseting the flags is done along the common error and errorless execution path. The list of idempotent error is extended with foreign keys related items. NDB engine write events are designed with the replace sematics in mind. Therefore the corrsponding ndb handler's flag are (re)set regardless of the slave's execution mode. Rows_log_event::write_row() starts using the bool replace argument as its caller sets it depending on the event's execution mode. sql/log_event.h: adding a new member to hold the slave's mode during execution of the event. sql/mysql_priv.h: changes to link the command line option with the new global sys var. sql/mysqld.cc: introduction of the new command line option. providing its initialization to a default. changes to link the command line option with the new global sys var. sql/rpl_rli.cc: rli post-event-execution cleanup restores the default bits. sql/set_var.cc: The new "standard" sys_var_set class' and the new global system var related declarations and definitions. fix_slave_exec_mode() is used as with the update method of a new class so as at time of the command line arguments parsing. sql/set_var.h: new declarations. The class for the new global sys var is based on yet another new "standard" one. sql/share/errmsg.txt: slave_exec_mode setting error; slave inconsistency error which may be not an error when the intention is "idempotent". I.e consisting of row-based events binlog is being applied for the 2nd (more) time. sql/sql_class.h: The names for the bits of the new sever slave_exec_mode_options. mysql-test/suite/rpl/t/rpl_idempotency-master.opt: innodb is necessary mysql-test/suite/rpl/t/rpl_idempotency-slave.opt: innodb is necessary, as well as the tests start with non-default IDEMPOTENT slave execution mode.
