# BUG#22045032 - SQL_THREAD OF BINLOG-LESS SLAVE FAILS WITHOUT ANY MESSAGE FOR
# VIEW_CHANGE EVENT
#
# This test verifies that the slave server with binlog disabled is able to
# skip the view change events when replicating from a member which is part of
# a Group.
#
# Bug#24754462 - ADD MTR TEST RELATED TO MYSQLBINLOG IN GR
# This test also checks replaying of mysqlbinlog output of GR member on a
# binlog-less server and verifies that binlogless server cannot be added to
# the GR group.
#
# Test:
# 0. The test requires three servers: M1, M2 and M3.
# 1. Bootstrap start a group on M1. Start GR on M2 and add some data.
# 2. Connect the third server to one of the member of the group, establishing
# an asynchronous replication connection (M1->M3). Start slave on M3.
# 3. On the slave (M3), test that the data is properly replicated after the
# start slave is completed. Diff check the table on M1 and M3.
# 4. Verify if the available backup (binlog file) can be later restored
# successfully on a binlogless-server.
# 5. Verify if binlogless-server cannot be added to the GR group
# 6. Ensure that the test is cleaned up and closed.
