The binlogrouter needs to manipulate the protocol structures in order for
the resultset buffering to work correctly. If the state isn't manipulated
for COM_QUERY statements, the resultsets aren't buffered and will be
routed in separate buffers.
Non-replication events were implicitly ignored but this was removed in a
recent change. The code that wasn't previously used didn't break the
replication event handling loop.
Events larger than 16MBytes are now encrypted when being saved.
Some changes to binlog event details report and maxbinlogcheck supports
-H option for replication header display
Storing the large events in memory allows checksum calculations to be done
in one step. This also makes the encryption of events easier as they
require the complete event in memory.
The backend protocol module can be requested to provide complete and
contiguous packets to the router module. This removes the need to process
the packets in binlogrouter.
