# Bug#27368735 BINLOG NAME AND POS ARE WRONG IN GROUP_REPLICATION_APPLIER
|
|
# CHANNEL'S ERROR MSGS
|
|
# Problem: When group_replication_applier channel's applier thread is facing
|
|
# an error, master_log_name and end_log_pos in the error message
|
|
# are incorrect.
|
|
#
|
|
# Steps to reproduce:
|
|
# ===================
|
|
# 0) Test require two servers in the group
|
|
# 1) Create a table with a primary key on both servers.
|
|
# 2) Have a tuple with key '1' on server2.
|
|
# 3) Insert the same tuple on server1 and try to sync on server2.
|
|
# 4) Sync (applier thread on server2) will fail because of
|
|
# the duplicate key error.
|
|
# 5) Check that the error says master_log_name and end_log_pos as <unknown>
|
|
# instead of displaying wrong values.
|
|
# 6) Cleanup (drop table on both servers)
