Functionality Added or Changed

• The --rename option now works with both full and partial restores:

  • If the --include-tables and --exclude-tables options are not used, all tables in the backup are restored, with the table selected by the --rename option renamed as specified.

  • If the --include-tables and --exclude-tables options are used, all tables selected by the two options together are restored, with the table selected by the --rename option renamed as specified.

Bugs Fixed

• There were sporadic failures of backups involving encrypted InnoDB tables with the error "The encrypted table . . . is not initialized" when repeated DDL operations on the tables took place during the backup operations. (Bug #32495740)

• When backing up tables that used MySQL Enterprise Transparent Data Encryption (TDE), if no password was provided using the --encrypt-password option, mysqlbackup quit unexpectedly. With this fix, mysqlbackup throws a proper error and aborts the operation in the situation. (Bug #32486697)

• Backups failed when backing up tables that used the keyring_hashicorp plugin for InnoDB table encryption. (Bug #32284801)

• mysqlbackup quit unexpectedly at the end of a backup to a tape using the NetWorker software. (Bug #32081275)

• The --include-tables and --exclude-tables options were ignored during a restore of a TTS backup taken with full locking (i.e., with --use-tts=with-full-locking). (Bug #31947026)

• A restore of a compressed backup failed if the backed-up server did not use .ibd as the extension for InnoDB tablespaces. (Bug #31596356)

• Backups for a server containing encrypted InnoDB tables failed when the server was of 64-bit and mysqlbackup was of 32-bit (or vice versa). It was due to the way keyring files were handled in the situation, which has been fixed by this patch. (Bug #29292085)
