Changes in MySQL NDB Cluster 7.4.19 (5.6.39-ndb-7.4.19) (2018-01-23, General Availability)

Bugs Fixed

  • NDB Cluster APIs: A previous fix for an issue, in which the failure of multiple data nodes during a partial restart could cause API nodes to fail, did not properly check the validity of the associated NdbReceiver object before proceeding. Now in such cases an invalid object triggers handling for invalid signals, rather than a node failure. (Bug #25902137)

    References: This issue is a regression of: Bug #25092498.

  • NDB Cluster APIs: Incorrect results, usually an empty result set, were returned when setBound() was used to specify a NULL bound. This issue appears to have been caused by a problem in gcc, limited to cases using the old version of this method (which does not employ NdbRecord), and is fixed by rewriting the problematic internal logic in the old implementation. (Bug #89468, Bug #27461752)

  • Queries using very large lists with IN were not handled correctly, which could lead to data node failures. (Bug #27397802)

    References: See also: Bug #28728603.

  • ndb_restore sometimes logged data file and log file progress values much greater than 100%. (Bug #20989106)

  • When sending priority A signals, we now ensure that the number of pending signals is explicitly initialized. (Bug #88986, Bug #27294856)

  • ndb_restore --print-data --hex did not print trailing 0s of LONGVARBINARY values. (Bug #65560, Bug #14198580)
