hi,
when i read patchs from
http://bazaar.launchpad.net/~knielsen/maria/dingqi-parallel-replication/changes,
i found a problem (maybe would cause bug) :main SQL thread read a event from
relay log, it make the log_event->thd point to the thd of main SQL thread. But
when a log_event is disaptched to a sub SQL thread, the log_event->thd still
point to the old value instead of the thd of sub SQL thread.
this problem will lead check_stack_overrun() fails, then lead open_table()
fails...
maybe this will be helpful to you .
