MariaDB 10.5.5 Release Notes
Notable Changes
Deprecated variables
* innodb_thread_concurrency
* innodb_commit_concurrency
* innodb_replication_delay
* innodb_concurrency_tickets
* innodb_thread_sleep_delay
* innodb_adaptive_max_sleep_delay
InnoDB
* Fixed corruption in delete buffering
* Fixed a deadlock in FLUSH TABLES…FOR EXPORT
* InnoDB data file extension is not crash-safe
* Minor fixes related to encryption and FULLTEXT INDEX
* Dropping the adaptive hash index may cause DDL to lock up InnoDB
* innodb_log_optimize_ddl=OFF is not crash safe
* Mariadb service won't shutdown when it's running and the OS datetime
updated backwards
* Doublewrite recovery can corrupt data pages
* Fixed race conditions related to buffer pool resizing
* ALTER TABLE fixes
* Slow InnoDB shutdown on large instance
* Fixes to performance regressions introduced in MariaDB 10.5.4
* Performance improvements
* Correctly implemented the scrubbing of freed pages
* Crash recovery fixes
Replication
* Make the binlog dump thread to log into errorlog a requested GTID
position
* Fix stop of the optimistic parallel slave at requested START-SLAVE-UNTIL
position
* Properly handle RESET MASTER TO value, when the value exceeds the max
allowed 2147483647
* Correct 'relay-log.info' updating by concurrent parallel workers
* Eliminate deadlock involving parallel workers, STOP SLAVE and FLUSH
TABLES WITH READ LOCK
* Correct master-slave automatic reconnection by slave to always pass
through all steps
of the initial connect. Specifically, do not skip master notification
about slave
binlog checksum awareness
* Refine mysqlbinlog output to print out START TRANSACTION at
Gtid_log_event
processing which satisfies clients that submit the output with
sql_mode=oracle
* Replication aborts with ER_SLAVE_CONVERSION_FAILED upon CREATE ...
SELECT in ORACLE mode
Optimizer
* ALTER TABLE ... ANALYZE PARTITION ... with EITS reads and locks all rows
...
* Print ranges in the optimizer trace created for non-indexed columns when
optimizer_use_condition_selectivity >2
Now the optimizer trace shows the ranges constructed while getting
estimates from EITS
* LATERAL DERIVED is not clearly visible in EXPLAIN FORMAT=JSON, make
LATERAL DERIVED tables visible in EXPLAIN FORMAT=JSON output
* Crash on WITH RECURSIVE large query
* Crash with Prepared Statement with a '?' parameter inside a re-used CTE
Other
* MariaDB could crash after changing the query_cache size
* Errors and SIGSEGV on CREATE TABLE w/ various charsets
* Crash in CREATE TABLE AS SELECT when the precision of returning type = 0
* XA: Reject DDL operations between PREPARE and COMMIT
* Stop mariabackup --prepare on errors during innodb redo log applying
* Server crashes in mysql_alter_table upon adding a non-null date column
under
NO_ZERO_DATE with ALGORITHM=INPLACE
* Can't uninstall plugin if the library file doesn't exist
* Mariabackup parameter cleanup
* Rounding functions return wrong datatype
* Create mariadb.sys user on each update even is the user is not needed
* INFORMATION_SCHEMA.INNODB_TABLESPACES_ENCRYPTION required SUPER instead
PROCESS privilege
* Reinforce DDL operation rejection after XA PREPARE
* As per the MariaDB Deprecation Policy, this will be the last release of
MariaDB 10.5 for Ubuntu 19.10 Eoan and Fedora 30
