as we already have db_len in Log_event. Only if rewrite_db() changed the db we need a strlen (so we now do the strlen() in rewrite_db). Plus a test (we had none for --replicate-rewrite-db :( ). sql/log_event.cc: The goal is to get of rid of one strlen() per replication event in slave: we don't need to compute strlen(thd->db) as we already have db_len in the event; only case where we need to do a strlen() is if rewrite_db() changed the db. Note that db_len is always a meaningful value. It's 0 if event's db is 0. sql/slave.cc: rewrite_db now returns the len of the returned db. print_slave_db_safe() needn't call rewrite_db() as rewrite_db() is already called by caller. sql/slave.h: declaration updates for slave.cc
