      After single row substitutions there might appear new equalities.
      They should be properly propagated to all AND/OR levels the WHERE
      condition. It's done now with an additional call of remove_eq_conds().

      This patch almost totally revised the patch for bug mdev-4177.
      The latter had too many defects. In particular, it did not
      propagate multiple equalities formed when merging a degenerate
      disjunct into underlying AND formula.

      Fixed bug mdev-4894. · 6dd9f049
      Igor Babaev authored
      This a an old legacy performance bug.
      When a very selective range scan existed for the second table in a join,
      and, at the same time, there was another range condition depending on the
      fields of the first table, the optimizer chose a plan with
      'Range checked for each record'. This plan was extremely inefficient in
      comparison with the regular selective range scan.
      As a matter of fact the range scan chosen for each record was the same as
      that selective range scan. 
      
      Changed the test case for bug 24776 to preserve the old output for explain.

      MDEV-4409 - Fix deadlock in MySQL key cache code, that can happen if there is a key cache resize running in parallel with an update.
      
      If there is a key cache resize,a  thread writing to key cache, will pause waiting  until resize finishes. However this thread is won't be woken, because resize does not  signaling waiters anymore. This is a regression introduced in WL#86(segmented MyISAM key cache)
      The fix is to unconditionally release  threads waiting on resize_queue when resize  finishes, as in pre-WL#86 code.

      MDEV-4634 Crash in CONVERT_TZ · 0e44faf2
      Alexander Barkov authored
      Item_func_min_max::get_date() did not check the
      returned value against the fuzzy_date flags, so
      it could return a bad value to the caller that
      expects a good date (e.h. CONVERT_TZ).

      MDEV-4280: Assertion `empty_size == empty_size_on_page' failure in ma_blockrec.c or ER_NOT_KEYFILE on query with DISTINCT and GROUP BY
      This could happen when using Aria for internal temporary files (default case) and using DISTINCT.
      _ma_scan_restore_block_record() didn't work correctly if there was rows inserted, updated or deleted on the handler
      between calls to _ma_scan_remember_block_record() and _ma_scan_restore_block_record().
      The effect was that some DISTINCT queries that used remove_dup_with_compare() could fail.

        Ignore sql_yacc.hh

        scan_restore_pos() can return disk fault error.
      storage/maria/ma_blockrec.c:
        _ma_scan_remember_block_record() did incorrectly update scan.dir instead of scan_save.dir .
        _ma_scan_restore_block_record() didn't work correctly if there was rows inserted,updated or deleted on the handler
        between calls to _ma_scan_remember_block_record() and _ma_scan_restore_block_record().
        Fixed by adding counters for row changes and reading the current scan page if changes had been made.
