Notable Items

• InnoDB could crash if the definition of the InnoDB persistent statistics tables were incorrect. (MDEV-31740)

• Workloads that are bound by innodb_log_file_size would write out unnecessarily many data pages in an attempt to advance the log checkpoint. (MDEV-35155)

• The forced use of THD accessor functions hurts InnoDB performance (MDEV-37619)

• CHECK TABLE…EXTENDED could flag bogus corruption on a column prefix index. (MDEV-37659)

Partitioning

• Errors or assertion failure upon REPAIR on partitioned Aria table with misplaced rows (MDEV-33190)

Platform RedHat

• On Fedora, RHEL, and derivatives, depend on the mysql-selinux-1.0.14 package that provides the correct selinux rules for the /usr/sbin/mariadbd that is installed. (MDEV-24941)

Stored routines

• Crash when calling stored function in FOR loop argument (MDEV-26115)

• Wrong result json_table (MDEV-36319)

Those using InnoDB on raw devices will need to add an override for this. See https://mariadb.com/docs/server/server-management/starting-and-stopping-mariadb/systemd#useful-systemd-options (MDEV-36721)

Backup

• Parallel slave worker crashes During Backup at retrying (MDEV-37453)

Scripts & Clients

• mariadb-dump -T did not encode table names like the server did for frm files, so some tables can be created in the server, but not dumped with mariadb-dump -T, for example, a table con on Windows. (MDEV-37483)

• Using mytop with DBD-MariaDB and host=localhost specified resulted in an unexpected error because the driver did not expect a port 3306. Contribution thanks to Jean Weisbuch. (MDEV-37852)

Versioned Tables

• REPLACE on a precise-versioned table returns duplicate key error (ER_DUP_ENTRY) (MDEV-15990)

Prepared Statements

• Parameterized PS converts error to warning, causes replication problems (MDEV-34046)

mariabackup

• Fixed bug in maria-backup where maria-backup would crash during the 'maria_recovery' part.

This could happen if server was doing repair or creating indexes while the

backup was running. (MDEV-36860)

Platform Windows

• On Windows, when MSI package is installed, with ADDLOCAL parameter passed to msiexec.exe, and Visual C++ Redistributable package is not installed on the target machine, installation may fail during "create database" step. (MDEV-36938)

Replication

• Fix --master-retry-count=0 not infinite as described (MDEV-36002)

• Ensure that Annotate_rows is always written direct after GTID information, before any table_map events. Before this patch the event could be written in a random position in the binary log. This change make the place of the Annotate_rows event predictable.

  • When mixing transactional and not transactional tables in the same transaction, the Annotate rows event was not always written in the case of a rollback. This is now fixed. (MDEV-37356)

• ALTER TABLE ... ENGINE=MRG_MyISAM is now properly logged as an DDL. This ensure that the changed MERGE table cannot be used by a slave thread until after the ALTER command has been executed. (MDEV-37903)

Configuration

• Galera galera_new_cluster scipt and its systemd interactions was rewritten to avoid selinux errors. This will require the mysql-selinux-1.0.14+ version that is a dependency of the server in RPM+selinux distributions. (MDEV-37726)
