# === Purpose ===
#
# This test checks that when a binlog is generated by a server unaware of
# original commit timestamp (OCT), if it is applied in a 8.0+ server, the OCT
# will be correctly generated.
#
# === Implementation ===
#
# First, generate some transactions on the server.
# Run mysqlbinlog modified so that the "SET original_commit_timestamp" statement
# is not printed.
# The server is then reset so that the transactions can be applied again.
# Finally, check that the OCT of the replayed transactions is set to zero, since
# they were not originated in this server.
