Bugs Fixed

• NDB Client Programs: ndb_restore, when applying the log, allowed an infinite number of retries due to temporary errors, rather than limiting these to 11 as expected. (Bug #37883579)

  References: This issue is a regression of: Bug #31546136.

• NDB Client Programs: When restoring from backup with DefaultOperationRedoProblemAction=ABORT, an error in data node handling of a redo log part overload condition resulted in an incorrect error code (626 in this case) being sent back to ndb_restore, which caused ndb_restore to exit prematurely since it did not expect such an error. (Bug #37687485)

  References: This issue is a regression of: Bug #13219, Bug #13930, Bug #13980.

• Improved password handling for file system encryption.

  Our thanks to Axel Svensson for the contribution. (Bug #37909595)

• CREATE TABLESPACE, when the specified logfile group did not exist, was rejected with error 723 No such table existed, which did not correctly identify the source of the problem with the SQL statement. Now in such cases, the server issues Error 789 Logfile group not found. (Bug #37802388)
