      Fix:
      ====
      
      Do not use THD::LOCK_thd_data mutex if we already hold lock_sys->mutex because it
      will cause mutexing order violation. Victim transaction holding conflicting
      locks can't be committed or rolled back while we hold lock_sys->mutex. Thus,
      it is safe to do wsrep_thd_is_BF call with no additional mutexes.

      MDEV-20939: Race condition between mysqldump import and InnoDB persistent · cbc75e99
      Rucha Deodhar authored
      statistics calculation
      
       Analysis: When --replace or --insert-ignore is not given, dumping of
      mysql.innodb_index_stats and mysql.innodb_table_stats will result into race
      condition.
      Fix: Check if these options are present with --system=stats (because dumping
      under --system=stats is safe). Otherwise, dump only structure, ignoring data
      because innodb will recalculate data anyway.

      MDEV-24709 Assertion !recv_no_ibuf_operations failed in ibuf_page_low() · 5fd3c747
      Marko Mäkelä authored
      recv_recovery_from_checkpoint_start(): Clear the recv_no_ibuf_operations
      flag at the same time when we enabled writes to the log.
      
      The failure to clear the flag might have caused some missed
      change buffer merges, at least to the secondary index of SYS_TABLES
      that were accessed by trx_resurrect_table_locks() while the last
      recovery batch was in progress.
      
      Thanks to Thirunarayanan Balathandayuthapani for suggesting this fix.

      fil_rename_tablespace(): Do not write a redundant MLOG_FILE_RENAME2
      record.
      
      The recovery bug will be fixed later. The problem is that we are
      invoking fil_op_replay_rename() too often, while we should skip
      any 'intermediate' names of a tablespace and only apply the
      very last rename for each tablespace identifier, and only if
      the tablespace name is not already correct.

      MDEV-24675 Server crash when table value constructor uses a subselect · bdae8bb6
      Igor Babaev authored
      This patch actually fixes the bug MDEV-24675 and the bug MDEV-24618:
      Assertion failure when TVC uses a row in the context expecting scalar value
      
      The cause of these bugs is the same wrong call of the function that fixes
      value expressions in the value list of a table value constructor.
      The assertion failure happened when an expression in the value list is of
      the row type. In this case an error message was expected, but it was not
      issued because the function fix_fields_if_needed() was called for to
      check fields of value expressions in a TVC instead of the function
      fix_fields_if_needed_for_scalar() that would also check that the value
      expressions are are of a scalar type.
      The first bug happened when a table value expression used an expression
      returned by single-row subselect. In this case the call of the
      fix_fields_if_needed_for_scalar virtual function must be provided with
      and address to which the single-row subselect has to be attached.
      
      Test cases were added for each of the bugs.
