      Description

      MySQL 5.7.31 includes the following InnoDB changes:

      Not applicable to MariaDB Server

      Bug#30875956 : PURGE ACTIVITY IS TOO MUCH AT CPU% BOUND AND CAUSES IDLE OVERDRIVE (and a follow-up to wake up purge on ANALYZE TABLE)
      This is adding conditions to the callers of srv_wake_purge_thread_if_not_active() and also adding some extra calls to that function. MDEV-11802 should already have fixed this.

      Bug #29759555 INNODB: PAGE [PAGE ID: SPACE=1337, PAGE NUMBER=39] STILL FIXED OR DIRTY
      This is fixing a regression that was introduced in MySQL 5.7.26. That change was not applicable to MariaDB. (MDEV-19342 explains that MDEV-11487 had removed the code from MariaDB.)

      Bug #29451999 CRASH WITH RANGE QUERIES
      This is yet another follow-up fix to Bug#23481444 OPTIMISER CALL ROW_SEARCH_MVCC() AND READ THE INDEX APPLIED BY UNCOMMITTED ROWS, which we chose not to apply to MariaDB already in MDEV-11751.

      Bug #30770380 INNODB: IBUF CURSOR RESTORATION FAILS!
      This change is suppressing an error message in the change buffer, related to the WL#6501 TRUNCATE TABLE implementation of MySQL 5.7. MDEV-13564 replaced that implementation. The error message is only possible in MariaDB 10.2 when using the non-default setting innodb_safe_truncate=OFF.

      Applicable to MariaDB Server

      Bug #98990 avg_count_reset for monitor set owner is always NULL in I_S.INNODB_METRICS
      Filed as MDEV-23161.
