# Bug#21276561: FAILURE TO GENERATE GTID LEADS TO INCONSISTENCY
#
# Problem:
# =======
# If generating a GTID for a transaction fails, the  transaction is not written
# to the binary log but still gets  committed, which potentially leads to
# master/slave data inconsistency.
#
# Test:
# =====
# Simulate a scenario such that generation of GTID number reaches its maximum
# value and the new GTID cannot be generated because of that. Verify that this
# fatal error case is appropriately handled as per the binlog_error_action
# value specified by user.
