#
# Test case to verify when roles changes in Group Replication
# then weight is re-assigned based on role change.
#
# Test:
# 0. This test needs 3 servers:
# server1: primary
# server2: secondary
# server3: single server replica
# 1. Start GR on M1(primary) and M2(secondary)
# 2. Add asynchronous connection failover servers and
# verify that they are inserted successfully in
# performance_schema.replication_asynchronous_connection_failover.
# 3. Create and start new channel ch1_3: M3(replica), M1(source)
# and verify channel ch1_3 IO and SQL THREADS are ON.
# 4. Verify 2 senders are added automatically to
# replication_asynchronous_connection_failover table.
# 5. Make M2 primary.
# 6. Verify M2 is new source with higher weight in
# performance_schema.replication_asynchronous_connection_failover
# 7. Switch to multi primary mode.
# 8. Verify M1 and M2 both have same primary_weight.
# 9. Switch to single primary mode with M1 as primary.
# 10. Verify M1 has higher weight and M2 has lower weight.
# Verify M1 is new source.
# 11. Cleanup.
