BUG#28618 (Skipping into the middle of a group with

Browse Source 
SQL_SLAVE_SKIP_COUNTER is possible):

By setting the SQL_SLAVE_SKIP_COUNTER it was possible to start the
from the middle of a group. This patch adds code so that events that
do not end a statement are ignored instead of skip counted when the
slave skip counter is 1.


sql/log_event.cc:
  Adding code so that for rows log events where the STMT_END_F is clear
  and for table map events, the event is ignored when the slave skip
  counter is 1 instead of skip counted, or described another way, the
  slave skip counter can only be decreased from 1 to 0 when the
  STMT_END_F flag is set.
sql/log_event.h:
  Adding functions Table_map_log_event::do_shall_skip() and
  Rows_log_event::do_shall_skip().
