Notable Items

InnoDB

• DROP INDEX followed by CREATE INDEX may corrupt data (MDEV-32132)
• ROW_FORMAT=COMPRESSED table: InnoDB: 2048 bytes should have been read. Only 0 bytes read. (MDEV-31875)
• Server aborts during alter operation when table doesn't have foreign index (MDEV-32527)
• row_merge_fts_doc_tokenize() handles FTS plugin parser inconsistently (MDEV-32578)
• InnoDB: tried to purge non-delete-marked record of an index on a virtual column prefix (MDEV-30024)
• lock_row_lock_current_waits counter in information_schema.innodb_metrics may become negative (MDEV-30658)
• SET GLOBAL innodb_max_purge_lag_wait=… hangs if innodb_read_only=ON (MDEV-31813)
• Auto-increment no longer works for explicit FTS_DOC_ID (MDEV-32017)
• Assertion `pos < table->n_def' failed in dict_table_get_nth_col (MDEV-32337)
• innochecksum man pages seem to be inconsistent with the binary (10.2.25) (MDEV-20583)
• innodb_compression_algorithm=0 (none) increments Innodb_num_pages_page_compression_error (MDEV-30825)
• wrong table name in innodb's "row too big" errors (MDEV-32128)
• Optimize is_file_on_ssd() to speedup opening tablespaces on Windows (MDEV-32228)
• Race condition between page write completion and log checkpoint (MDEV-32511)
• After crash recovery, Checksum mismatch + Failing assertion: !i || prev_id + 1 == space_id, (MDEV-31851)
• Deadlock due to log_free_check(), involving trx_purge_truncate_rseg_history() and trx_undo_assign_low() (MDEV-32049)
• Write-ahead logging is broken for freed pages (MDEV-32552)
• X-lock on supremum for prepared transaction for RR (MDEV-30165)
• Assertion failures in log_sort_flush_list upon crash recovery (MDEV-32029)
• Assertion `purge_sys.tail.trx_no <= purge_sys.rseg->last_trx_no()' (MDEV-30100)
• Assertion `index->is_btree() || index->is_ibuf()' failed in btr_search_guess_on_hash (MDEV-30802)

  • Deprecate innodb_purge_rseg_truncate_frequency.
  • The motivation for introducing this in MySQL seems to have been to avoid stalls due to freeing undo log pages or truncating undo log tablespaces. In MariaDB, innodb_undo_log_truncate=ON should be a much lighter operation because it will not involve any log checkpoint. (MDEV-32050)
