Notable Items

InnoDB

Replication

Galera

  • Galera updated to 26.4.12
  • 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)
  • Implement a method to add IPs to allowlist for Galera Cluster node addresses that can make SST/IST requests (MDEV-27246)

Optimizer

  • 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.
  • Assertion `tmp >= 0' failed in best_access_path (MDEV-28882)
    • If one uses histogram_type=JSON_HB, has collected a histogram of that type and runs a query that selects a very narrow range near histogram end, they can hit an assertion in the optimizer due to rounding errors in the histogram causing negative selectivity.
