Changes in MySQL NDB Cluster 7.3.24 (5.6.43-ndb-7.3.24) (2019-01-22, General Availability)

Bugs Fixed

• Asynchronous disconnection of mysqld from the cluster caused any subsequent attempt to start an NDB API transaction to fail. If this occurred during a bulk delete operation, the SQL layer called HA::end_bulk_delete(), whose implementation by ha_ndbcluster assumed that a transaction had been started, and could fail if this was not the case. This problem is fixed by checking that the transaction pointer used by this method is set before referencing it. (Bug #20116393)
