replication_timestamps.inc

# The test file is invoked from rpl.rpl_multi_source_timestamps.test
# and group_replication.gr_replication_timestamps
#
# This file has two main sections:
#   1) Retrieve the OCT and ICT from each server
#   2) Verify that the timestamps are correct
#
# param $gtid - the gtid of the transaction to be checked
# param $master - the master server.
# param $slave  - the slave server.
# param $check_master_OCT - if 1, then the test checks if the OCT == ICT in the
#                           master. Not applicable when a transaction was
#                           originated by a group member.
#                           if 0, the test asserts that the OCT and ICT were
#                           correctly generated by the group member.
# param $check_master_slave_ICT - if 1, then the test checks if the ICT
#                                 increases from master to slave. Not applicable
#                                 between group members.
#                                 if 0, the test asserts that the group member
#                                 replicating the transaction correctly
#                                 generated the ICT.
