#
# 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.
