# Verify that the wsrep XID gets updated in InnoDB rollback segment
|
|
# properly and can be recovered with --wsrep-recover
|
|
#
|
|
# The test runs the following scenarios:
|
|
#
|
|
# 1) The server is started but no SQL is run
|
|
# 2) DDL is executed
|
|
# 3) INSERT is executed
|
|
# 4) Two INSERTs are executed so that the first one in order will be
|
|
# blocked after certification and the second one before entering
|
|
# commit order critical section.
|
|
# 5) Two DMLs are executed so that the prepare step is run out of order.
|
|
# Both transactions are blocked before commit order critical section.
|
|
#
|
|
# After each scenario server is killed and the recovered position
|
|
# is validated.
