#
# Validate that:
# - The Automatic Connection failover feature for Receiver works when
# asynchronous replication receiver is a Primary member.
# - Whenever there is a running Managed channel receiver who is also the
# Primary on a Single-primary group, if the Primary changes, then the new
# selected Primary of the receiver group MUST establish asynchronous
# replication connection with the sender, provided
# mysql_start_failover_channels_if_primary internal member action is
# enabled on the receiver group.
#
# Test:
# 0. The test requires 4 servers:
# server1: single-primary group A primary
# server2: single-primary group A secondary
# server3: single-primary group B primary
# server4: single-primary group B secondary
# 1. Create a replication channel to replicate from server4 to
# to server1 on both server1 and 2.
# 2. Deploy a 2 members receiver group in single primary mode.
# 3. Deploy a 2 members sender group in single primary mode.
# 4. Add replication connection details of managed channel ch1
# to replication_asynchronous_connection_failover_managed table
# through asynchronous_connection_failover_add_managed() UDF.
# 5. Verify replication_asynchronous_connection_failover on
# server1 has two rows and member action configuration version
# value for replication_asynchronous_connection_failover
# and for replication_asynchronous_connection_failover_managed.
# 6. Verify replication_asynchronous_connection_failover on
# server2 has two rows and member action configuration version
# value for replication_asynchronous_connection_failover
# and for replication_asynchronous_connection_failover_managed.
# 7. Stop group replication on existing primary (server1), the new
# primary will establish asynchronous replication channel (ch1)
# connection with sender which is server4.
# 8. Delete replication connection details for managed channel ch1
# from replication_asynchronous_connection_failover_managed
# and replication_asynchronous_connection_failover table
# through asynchronous_connection_failover_delete_managed() UDF.
# 9. Verify replication_asynchronous_connection_failover on
# server2 is empty and member action configuration version
# value for replication_asynchronous_connection_failover
# and for replication_asynchronous_connection_failover_managed.
# 10. Verify replication_asynchronous_connection_failover on
# server1 is empty and member action configuration version
# value for replication_asynchronous_connection_failover
# and for replication_asynchronous_connection_failover_managed.
# 11. Clean up.
