Release date: 15 Aug 2022
Thanks, and enjoy MariaDB!
- InnoDB corruption due to lack of file locking (MDEV-28495)
- FULLTEXT search with apostrophe, and mandatory words (MDEV-20797)
- ALTER TABLE IMPORT TABLESPACE corrupts an encrypted table (MDEV-28779)
- ALTER TABLE wrong-result fix (MDEV-26294)
- Crash recovery fixes (MDEV-28668, MDEV-28731)
- DDL crash recovery fixes (MDEV-28752, MDEV-28802, MDEV-28864, MDEV-28870, MDEV-28923, MDEV-28977)
- Avoid crashes on corrupted data (MDEV-13542, MDEV-18519, MDEV-21098, MDEV-22388, MDEV-28457, MDEV-28950)
- Bulk load bug fixes (MDEV-28242, MDEV-28679)
- explicit_defaults_for_timestamp is stored in binlog, so that CREATE TABLE on slave would always have the same effect as on master. (MDEV-29078)
- ER_SLAVE_INCIDENT error is specified now on slave to be seen with SHOW-SLAVE-STATUS (MDEV-21087)
- INCIDENT_EVENT is no longer binlogged when a being logged transaction can be safely rolledback (MDEV-21443)
- sequences related row-format events are made to correspond to binlog_row_image (MDEV-28487)
- Possible reason of FLUSH BINARY LOGS hang is eliminated (MDEV-28948)
- Fix out-of-order gtid error in the circular semisync setup (MDEV-28609)
- Possible to write/update with read_only=ON and not a SUPER privilege (MDEV-28546)
- Node crashes with Transport endpoint is not connected mysqld got signal 6 (MDEV-25068)
- Galera4 not able to report proper wsrep_incoming_addresses (MDEV-20627)
- Galera should replicate nextval()-related changes in sequences with INCREMENT <> 0, at least NOCACHE ones with engine=InnoDB (MDEV-27862)
- Add support for OpenSSL 3.0 in Galera (MDEV-25949)
- Server crash in JOIN_CACHE::free or in copy_fields (MDEV-23809)
- Queries that use DISTINCT and an always-constant function like COLLATION(aggegate_func(...)) could cause a server crash. Note that COLLATION() is a special function - its value is constant even if its argument is not costant.
- Crash when using ANY predicand with redundant subquery in GROUP BY clause (MDEV-29139)
- A query with a subuquery in this form could cause a crash:
... ANY (SELECT ... GROUP BY (SELECT redundant_subselect_here)) ...
- MariaDB Server SEGV on INSERT .. SELECT (MDEV-26427)
- Certain queries in form "INSERT ... SELECT with_aggregate_or_window_func" could cause a crash.
- restore_prev_nj_state() doesn't update cur_sj_inner_tables correctly (MDEV-28749)
- Subquery semi-join optimization could miss LooseScan or FirstMatch strategies for certain queries.
- Optimizer uses all partitions after upgrade to 10.3 (MDEV-28246)
- For multi-table UPDATE or DELETE queries, the optimizer failed to apply Partition Pruning optimization for the table that is updated or deleted from.
- Range optimizer regression for key IN (const, ....) (MDEV-25020)
- The issue can be observed on MariaDB 10.5.9 and later versions which have the fix for MDEV-9750. That fix introduceds optimizer_max_sel_arg_weight.
- If one sets optimizer_max_sel_arg_weight to a very high value or zero (which means "unlimited") and runs queries that produce heavy-weight graphs, they can observe a performance slowdown, e.g.:
table.keyXpartY [NOT] IN ( ... )
- Wrong result with table elimination combined with not_null_range_scan (MDEV-28858)
- If one runs with optimizer_switch='not_null_range_scan=on' (which is not enabled by default), a query that does a join and has const tables could produce a wrong result.
- spider_init_sql_alloc_size and spider_buffer_size have been deprecated (MDEV-27926, MDEV-28560)
- Spider's high-availability feature has been deprecated (MDEV-28479)
- explicit_defaults_for_timestamp now also has a session scope, not only global (MDEV-29225)
- New mariadb client option,
-enable-cleartext-plugin. Option does not do anything, and is for MySQL-compatibility purposes only.
- Crash in JSON_EXTRACT (MDEV-29188)
- ALTER TABLE ALGORITHM=NOCOPY does not work after upgrade (MDEV-28727)
- Server crash upon CREATE VIEW with unknown column in ON condition (MDEV-29088)
- password_reuse_check plugin mixes username and password (MDEV-28838)
