# BUG 21649247 - DML(INSERT) WITH STOP AND START GR RESULTS INTO CRASH POST
|
|
# 'BEFORE_COMMIT' ERROR
|
|
#
|
|
# The test verifies that the concurrent execution of START/STOP
|
|
# GROUP_REPLICATION and DML executing does not crash.
|
|
#
|
|
# Test:
|
|
# 0) The test requires two servers: M1 and M2.
|
|
# 1) With both members ONLINE. Create table t1 on M1. Then, block the stop
|
|
# group_replication after recovery module termination using DEBUG point.
|
|
# 2) Execute a DML to check if it crashes.
|
|
# 3) Check if the DML executing is blocked at this point.
|
|
# 4) Signal the waiting thread on stop group_replication.
|
|
# 5) Check for consistency on the two servers.
|
|
# 6) Clean up.
