# Bug#22540 - Incorrect value in column End_log_pos of
# SHOW BINLOG EVENTS using InnoDB
#

# the following tests will show that certain queries now return
# absolute offsets (from binlog start, rather than relative to
# the beginning of the current transaction).  under what
# conditions it should be allowed / is sensible to put the
# slider into the middle of a transaction is not our concern
# here; we just guarantee that if and when it's done, the
# user has valid offsets to use.  if the setter function still
# wants to throw a "positioning into middle of transaction"
# warning, that's its prerogative and handled elsewhere.
