# This test verifies that group replication channels are not affect by global
# RESET SLAVE commands when the group replication is running.
# If a command is used directly in a group channel it should work.
# If a command is used when group replication is stopped it should work.
#
# Test:
# 0. The test requires two servers: M1, M2 and M3.
#
# 1. Phase 1: Setup a 2 server group.
#  a) Check that the applier files are not there before start GR.
#  b) Bootstrap start group on M1. Add some data for recovery.
#  c) Start GR on M2.
#  d) Create a slave channel on M1 with M3 i.e. M3 -> M1.
#
# 2. Phase 2: Check that the group replication applier files are present.
#  a) On M1, group applier files should now be present with the channel.
#  b) On M1, slave files should be present.
#  c) On M2, group applier files should now be present with the channel.
#  b) On M2, recovery files should be present.
#
# 3. Phase 3: Check that the RESET SLAVE command doesn't affect GR specific
#    channels when the GR member is ONLINE.
#  a) Execute RESET SLAVE ALL command on M1.
#  b) Validate that group applier files are still present on M1.
#  c) Check that slave files are removed on M1.
#
# 4. Phase 4: After a direct reset command all files should disappear.
#  a) RESET SLAVE ALL command should fail on an ONLINE member M1.
#  b) Stop GR on M1.
#  c) Execute RESET SLAVE ALL command on M1.
#  d) Validate that group applier files are removed.
#
# 5. Phase 5: Restart server 1 plugin, all should be fine.
#  a) Add some data for recovery on M2.
#  b) Start GR on M1.
#  c) Add some data on M1 to check if all is fine.
#  d) Validate that both members have all the data.
#
# 6. Phase 6: When GR is stopped, after global reset command all files
#    should disappear.
#  a) Stop GR on M2.
#  b) Execute RESET SLAVE command on M2
#  c) Validate that slave_master_info and slave_relay_log_info tables are
#     cleared.
#  d) Start GR on M2. The node should be ONLINE.
#
# 7. Phase 7: When GR is stopped, after global RESET SLAVE ALL command all
#    files should disappear including recovery channel specific credentials.
#  a) Stop GR on M2.
#  b) Execute RESET SLAVE ALL command on M2
#  c) Validate that slave_master_info and slave_relay_log_info tables are
#  cleared.
#  d) Execute CHANGE MASTER command to provide recovery channel credentials.
#  f) Start GR on M2. The node should be ONLINE.
#
# 6. Phase 6: Cleanup.
