Release Notes for MariaDB Enterprise Server 10.3.32-14

MariaDB Enterprise Server 10.3.32-14 is a maintenance release of MariaDB Enterprise Server 10.3. This release includes a variety of fixes.

MariaDB Enterprise Server 10.3.32-14 was released on 2021-12-13.

Fixed Security Vulnerabilities

Notable Changes

• Galera updated to 25.3.35

• Enterprise Spider no longer enables pushdown of UDFs and Stored Functions to the Data Node by default: (MDEV-26545)
  • The default value of spider_use_pushdown_udf has changed from -1 to 0
  • In previous releases, Enterprise Spider pushed UDFs and Stored Functions down to the Data Node by default, which could cause query results to be inconsistent.
  • Starting with this release, all UDFs and stored functions are evaluated on the Spider Node by default. If desired, pushdown of UDFs and Stored Functions can be explicitly enabled by setting spider_use_pushdown_udf=1. Testing is recommended to confirm that query results are consistent.

• Performance Schema tables provide descriptions of each column in the COMMENT column option. (MDEV-25325)

Issues Fixed

Can result in a hang or crash

• MariaDB Enterprise Cluster, powered by Galera, can crash on INSERT if the table does not have a primary key and if the data for a field exceeds 4096 bytes. (MDEV-24978)

• When an InnoDB tablespace (.ibd) file is imported using ALTER TABLE .. IMPORT TABLESPACE without a corresponding .cfg file, InnoDB causes a server crash. (MDEV-26131, MDEV-20931)

• When OPTIMIZE TABLE (or mariadb-check -o) is executed against an InnoDB table with a FULLTEXT index, InnoDB can cause a server crash. (MDEV-25702, MENT-1198)

• Resolving aggregate functions that are used in a view can cause in a crash. (MDEV-24454)

• Executing CREATE OR REPLACE TABLE AS SELECT under LOCK TABLE can cause in a crash. (MDEV-23391)

• If two InnoDB tables have a foreign key and an operation cascades from the parent table to the child table, an index on a virtual generated column in the child table can become corrupt. (MDEV-26866)

• MariaDB Enterprise Cluster, powered by Galera, crashes with errors like:
  [ERROR] WSREP: Trx 236236 tries to abort slave trx 236238 (MDEV-25835)

• Server crashes when a table uses a sequence as a column default (DEFAULT NEXT_VALUE(my_seq)) and the table is used concurrently by both a prepared statement and a normal statement. (MDEV-22785)

• MariaDB Enterprise Cluster can crash due to an incorrect conflict resolution on multi-master setup. (MDEV-25992, MDEV-25114)

Can result in unexpected behavior

• skip_networking does not prevent replication. (MDEV-24969)

• MariaDB Enterprise Cluster joiner node incorrectly uses localhost for TLS certificate verification and fails to join cluster when wsrep_sst_method=mariabackup and encrypt=3 are configured. (MDEV-26360)

• mariadb --binary-mode is not able to replay some mysqlbinlog outputs if
0 is in the data. (MDEV-25444)

• Memory leak with row-based replication can lead to high memory usage on replica servers. (MDEV-26712)

• SHOW CREATE VIEW and mariadb-dump generate invalid SQL for some complex views. (MDEV-26299)

• When statement-based or mixed replication is used and a DML statement encounters an error in a transaction that creates or drops a temporary table, non-committed writes to transactional tables can be incorrectly replicated to replica servers. (MDEV-26833)

• MariaDB Enterprise Cluster joiner node fails to join cluster when wsrep_sst_method=mariabackup and Backward Compatible SST TLS Mode is configured. (MDEV-26211)

• Spider does not work correctly for UDF and stored functions if used in a query's WHERE conditions. (MDEV-26545)

• On a partitioned Spider table, result of SELECT wrongly depends on the partition targeted by the previous SELECT (MDEV-26333)

• If an INVISIBLE column has a computed default value, an INSERT statement that doesn't specify a value for the column causes the default value to be ignored. (MDEV-25891)
