The test and also rpl_gtid_delete_domain failed on PPC64 platform due to an incorrectly specified actual key for searching in a gtid domain system hash. While the correct size is 32 bits the supplied value was 8 bytes of long int size on the platform. The problem became evident thanks to the big endiness which cut off the *least* significant part of the value field. Fixed with correcting a dynamic array initialization to hold now uint32 values as well as the values extraction for searching in the gtid domain system hash. A new added test ensures no overflowed values are accepted for deletion which prevents inadvertent action. Notice though MariaDB [test]> set @@session.gtid_domain_id=(1 << 32) + 1; MariaDB [test]> show warnings; +---------+------+--------------------------------------------------------+ | Level | Code | Message | +---------+------+--------------------------------------------------------+ | Warning | 1292 | Truncated incorrect gtid_domain_id value: '4294967297' | +---------+------+--------------------------------------------------------+ MariaDB [test]> select @@session.gtid_domain_id; +--------------------------+ | @@session.gtid_domain_id | +--------------------------+ | 4294967295 | +--------------------------+ |
