Bug Description
We downloaded and start using the mirror bin-log patches, but the behavior is strange. Both master and slave have same version i.e. 5.0.67-
1] I was under impression before starting the replication it will download all the prior bin-log files to slave, but that does not happen. It just download the recent one i.e one specified in "change master " command.
2] If I stop replication for backup or business needs like keeping slave few hours behind, the bin-log file on slave gets all the events from master starting from beginning. It does not take into account that the replication is merely resuming and do not need all the events right from beginning. Otherway if it has to do then it should overwrite and not append.
