Notable Items

Storage Engines

InnoDB

• Fatal InnoDB error: Unknown error Temp file write failure ()

• AUTO_INCREMENT leads to non-serializable on results ()

Data Definition - Alter Table

Server

mariadb-backup

• This commit fixes a bug where Aria tables are used in (master->slave1->slave2) and a backup is taken on slave2. In this case it is possible that the replication position in the backup, stored in mysql.gtid_slave_pos, will be wrong. This will lead to replication errors if one is trying to use the backup as a new slave. ()

Galera

• updated to 26.4.23

• galera_3nodes.inconsistency_shutdown test occasionally hangs ()

• Galera-26.4.23 corrects an incompatibility with OpenZFS >= 2.3.0 enabling the use of galera on this filesystem.

Authentication and Privilege System

• ALTER TABLE require ALTER privilege on sequence from DEFAULT value expression ()
