Issues Fixed

Can result in data loss

  • When executing a DELETE or UPDATE with a subselect, the server can crash. (MDEV-10087)
  • When performing an incremental backup, MariaDB Enterprise Backup does not reflect databases that have been dropped and created. (MDEV-23335)

Can result in a hang or crash

  • When DELETE HISTORY is executed for a system versioned table with full text index, the server can crash. (MDEV-25004)
  • When an ALTER TABLE statement causes InnoDB to rebuild a table with a spatial index, the server can crash. (MDEV-29856)

  • When executing REPLACE INTO ... PARTITION(...), the server can crash. (MDEV-29636)
  • Galera SST doesn't properly handle undo* files from InnoDB. As a result, SST may terminate incorrectly when --innodb-undo-tablespaces is set to 3 or more. (MDEV-30157)
  • With a query containing nested WINDOW clauses, the server can crash. (MDEV-30052)
  • When executing a SELECT from complex a view with WHERE clause and with the setting derived_merge=on, the server can crash. (MDEV-30081)
  • Infinite sequence of recursive calls when processing embedded CTE, when such a reference has the same table name as the name of the CTE. (MDEV-30248)
  • A deadlock between InnoDB statistics updates and BLOB insert can result in a server hang. (MDEV-29883)
  • GET_LOCK() / RELEASE_LOCK() calls are not rejected by MariaDB Enterprise Cluster. (MDEV-27115)
  • With a cluster wide conflict, MariaDB Enterprise Cluster can hang if a binlog purging is running (such as in the case that binlog expiration is configured). (MDEV-29512)
  • mariadbd hangs when running with --wsrep-recover and --plugin-load-add=ha_spider.so options. (MDEV-30370)

Can result in unexpected behavior

  • log_query_not_using_indexes=OFF is ignored when log_slow_filter is an empty string. (MDEV-21187)
  • MariaDB Enterprise Backup returns with an error when the option --galera-info is used for creating a backup of a MariaDB Server instance, which is not a MariaDB Enterprise Cluster node. Failed to get master wsrep state from SHOW STATUS (MDEV-30293)
  • When querying a table with virtual generated columns using full text search, these columns are not generated and are always NULL in the result set. (MDEV-29169)
  • Identifiers are not quoted for the output of SHOW GRANTS. Using the result to execute the grant statement results in a syntax error, if reserved keywords are used. (MDEV-30056)
  • Spider table with CHARSET utf32/utf16/ucs2 tries to set client CHARSET to unsupported value. (MDEV-29562)
  • Incorrect results are returned when using STDDEV_SAMP() with a view. (MDEV-19071)
