# ==== Purpose ====
#
# Test that the sync chain generated by
# include/rpl_change_topology.inc (sourced from include/rpl_init.inc)
# is correct.
#
# We test a number of different topologies.  Each topology is tested
# in include/rpl_test_framework.inc.  See
# include/rpl_test_framework.inc for details on how the sync
# chain is tested.
#
# ==== Related bugs ====
#
# BUG#49978: Replication tests don't clean up replication state at the end


# We only need to execute this test once. Also, we rely on 'DELETE
# FROM t1' to remove rows in slave tables that don't exist in master
# tables (see include/rpl_test_framework.inc for details).
