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
