# ==== Purpose ====
#
# Test verifies that slave IO thread can process heartbeat events with log_pos
# values higher than UINT32_MAX.
#
# ==== Implementation ====
#
# Steps:
# 0 - Stop slave threads. Configure a small master_heartbeat_period.
# 1 - Using debug points, simulate a huge binlog offset higher than
# UINT32_MAX on master.
# 2 - Start the slave and observe that slave IO thread is able to process
# the offset received through heartbeat event.
#
# ==== References ====
#
