# This file should be included from tests for MW-369 to run concurrent
|
|
# transaction from node_1 with autocommit query from node_2.
|
|
#
|
|
# The parameters:
|
|
# * $mw_369_parent_query - the parent query to be run inside transaction
|
|
# * $mw_369_child_query - the child query
|
|
#
|
|
# The operations are the following:
|
|
#
|
|
# node_1:
|
|
# START TRANSACTION;
|
|
# $mw_369_parent_query
|
|
# node_2
|
|
# $mw_369_child_query - will be blocked on node_1 in wsrep_apply_cb
|
|
# node_1:
|
|
# COMMIT; - will be blocked on node_1 in after_wsrep_before_prepare
|
|
#
|
|
# The $mw_369_child_query is always expected to succeed. The caller is
|
|
# responsible for checking if the final COMMIT on connection node_1
|
|
# succeeds.
|
|
#
