# ==== Purpose ====
#
# Verify that we do not allow users to modify the mysql.gtid_executed
# table explicitly by a XA transaction.
#
# ==== Implementation ====
#
# - Start a XA transaction and modify the mysql.gtid_executed
# table explicitly.
# - Check that the ER_ERROR_ON_MODIFYING_GTID_EXECUTED_TABLE error is caused.
# - Check that users can not modify mysql.gtid_executed table explicitly.
#
