# ==== Purpose ====
#
# This test verifies correctness and effectiveness of the
# until-stopping when the position used is inside the Gtid_log_event
# of a group (transaction) in the relaylog.
#
# ==== Method ====
#
# The test will create a two events transaction (GTID + QUERY), and will start
# the SQL thread using the UNTIL MASTER_LOG_FILE/POS clause, pointing to the
# first byte of the created transaction (inside of the Gtid_log_event).
#
# The test expects that, after issuing the START SLAVE SQL_THREAD with the
# UNTIL clause, the SQL thread will apply the created transaction (both
# GTID and QUERY events) even though pointing to stop after the GTID.
# The test also expects that the SQL thread will update its position
# before stopping.
#
# The test will then verify SQL thread's binlog file, position, and
# finally will wait for the SQL thread to stop.
#
# When the SQL thread stops, the test verifies if the second event of
# the transaction (QUERY) was successfully applied.
