To debug a the ddl_recovery code in a failing ddl_recovery test one could do the following: - Add # before --exec echo "restart" ... - Force $e (engine), $c (crash point) and $r (crash position) to the values where things goes wrong. See comments in alter_table.test for how to do this. - start mariadbd in a debugger run the following in the debugger (Replace 'atomic.create_trigger' with the failing test case) #break ha_recover #break MYSQL_BIN_LOG::recover #break MYSQL_BIN_LOG::open break ddl_log_close_binlogged_events break ddl_log_execute_action break ddl_log_execute_recovery run --datadir=/my/maria-10.6/mysql-test/var/log/atomic.create_trigger/mysqld.1/data --log-basename=master --log-bin-index=mysqld-bin.index --debug --log-bin
