Notable Items

InnoDB

Backup

  • mariadb-backup doesn't utilise innodb-undo-log-directory (if specified as a relative path) during copy-back operation (MDEV-28187)
  • mariabackup issues error messages during InnoDB tablespaces export on partial backup preparing (MDEV-29050)
  • mariadb-backup does not copy Aria logs if aria_log_dir_path is used (MDEV-30968)
  • Race condition between buffer pool flush and log file deletion in mariadb-backup --prepare (MDEV-30860)

Replication

  • Fixed a deadlock on parallel slave involving full image Write event on the sequence engine (MDEV-29621)
  • Fixed an attempted out-of-order binlogging error on slave involving ALTER on the sequence engine (MDEV-31077)
  • Corrected non-versioned master to versioned slave replication on no-unique attribute table (MDEV-30430)
  • Mended encrypted binlog master to error out to gtid-mode slave when master could not decrypt a binlog file (MDEV-28798)
  • Refined optimistic parallel slave to error-exit without any hang (MDEV-30780)
  • Ensured SHOW-SLAVE-STATUS is processed on the parallel slave having a necessary mutex always intialized (MDEV-30620)
  • Fixed the slave applier to report a correct error when gtid_slave_pos insert fails for some (engine) reasons (MDEV-31038)
  • Made parallel slave reports in performance schema consistent with that of show-slave-status (MDEV-26071)

Optimizer

  • Split Materialized optimization is improved to re-fill the materialized table only if necessary. The fewer number of table refills is taken into account when choosing query plan, too (MDEV-26301).
  • New optimizer_switch option, hash_join_cardinality, is added. It is off by default. When set to ON, the optimizer will produce tighter bounds for hash join output cardinality. (MDEV-30812)
  • Queries using SELECT DISTINCT some_expression(aggregate_function()) could produce wrong query result. (MDEV-20057)
  • ANALYZE FORMAT=JSON now prints more information about Block Nested Loop joins: block-nl-join element now has r_loops, r_effective_rows and r_other_time_ms fields (MDEV-30806, MDEV-30830, MDEV-30972).
  • A GROUP BY query with MIN(primary_key) in select list and primary_key<>const in the WHERE could produce wrong result when executed with "Using index for group-by" strategy (MDEV-30605)
  • EXPLAIN could erroneously report that Rowid Filter optimization is used for partitioned tables. Partitioned tables do not support it. (MDEV-30596)
  • A bug in selectivity computations for SINGLE/DOUBLE_PREC_HB histograms could cause wrong estimates to be produced. This could cause the optimizer to pick sub-optimal query plans (MDEV-31067).

Docker Official Image

  • Add replication setup to containers contributed by Md Sahil (MDEV-29762)
