# This test evaluates that group replication will fail when the applier fails
|
|
# applying events on start.
|
|
#
|
|
# The test guide is:
|
|
# 0. A two member group with started plugins
|
|
# 1. Create a table t1 on server 1 and replicate
|
|
# 2. Insert a row on server 2 with log to the binlog disabled
|
|
# 3. Write the same query in server 1
|
|
# On server 2 the duplicated key will make the applier fail.
|
|
# Server 2 will leave
|
|
# 4. Stop server 2 and start it again. One of three things can happen:
|
|
# A. The applier fails after the join and the member leaves the group
|
|
# but the START GROUP_REPLICATION command does not fail
|
|
# B. The applier fails after initialization and sets the state to ERROR,
|
|
# making the group join fail that makes the START GROUP_REPLICATION
|
|
# command fail with a generic ER_GROUP_REPLICATION_CONFIGURATION.
|
|
# C. The applier fails and its initialization processes catches the error.
|
|
# During the start, it is known that the applier failed so the START
|
|
# GROUP_REPLICATION fails with error ER_GROUP_REPLICATION_APPLIER_INIT_ERROR
|
|
# 5. Verify that member is offline after stop
|
|
# 6. Clean up
|
