Notable Items

Storage Engines

InnoDB

• Fatal InnoDB error: Unknown error Temp file write failure (MDEV-36017)

• AUTO_INCREMENT leads to non-serializable on results (MDEV-36330)

Data Definition - Alter Table

• Adding (with ALTER TABLE) a UNIQUE constraint that is USING HASH to a table with foreign keys could've caused the table to become corrupted. (MDEV-36852)

Partitioning

• Server crashes in do_mark_index_columns instead of ER_DUP_ENTRY on partitioned table (MDEV-36817)

Data Definition - Create Table

• CREATE OR REPLACE with self-referencing CHECK hangs forever, cannot be killed (MDEV-29155)

Server

• Segfault on INTERSECT ALL with UNION in Oracle mode (MDEV-25158)

• In certain cases privileges on sequences were too restrictive, for example, SELECT on a table might've erroneously required INSERT privilege on a sequences (MDEV-36870)

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. (MDEV-36143)

Galera

• Galera updated to 26.4.23

• galera_3nodes.inconsistency_shutdown test occasionally hangs (MDEV-36968)

Authentication and Privilege System

• ALTER TABLE require ALTER privilege on sequence from DEFAULT value expression (MDEV-36280)

Data Manipulation - Insert

• UNIQUE constraint that was USING HASH and UNIQUE constrant WITHOUT OVERLAPS could be violated under heavy load in READ COMMITTED transaction isolation mode. (MDEV-37199)

General

• Add analyze_max_length option to not collect statistics for long char/varchars (MDEV-36536)

• Packages for RHEL8 no longer depend on liburing. The RHEL8 kernel had insufficient kernel support so linking was an unneeded dependency. libaio was sufficient (MDBF-1042)
