# MDEV-32051 : Failed to insert streaming client
#
# Test outline:
# To reproduce we need a autocommit INSERT with streaming enabled,
# and a conflicting TRUNCATE.
# The INSERT is BF aborted by TRUNCATE during replication of the commit
# fragment, so that the INSERT must be rolled back replayed. During
# replay it fails certification, finally the statement is retried and
# succeeds. If bug is present, the streaming client for the INSERT does
# not get deleted after replay, causing the warning (or assert in debug builds)
# when retrying attempts to create the same streaming client with the same id.
#

CREATE TABLE t1 (f1 INTEGER PRIMARY KEY) ENGINE=InnoDB;
INSERT INTO t1 VALUES(1);
#
# Issue an INSERT and block it right before certification
# of the commit fragment. This is needed to setup for
# before_replicate_sync in galera, to make sure we catch
# the commit fragment.
