      Fixed bug mdev-4311 (bug #68749). · 323fdd7a
      Igor Babaev authored
      This bug was introduced by the patch for WL#3220.
      If the memory allocated for the tree to store unique elements
      to be counted is not big enough to include all of them then
      an external file is used to store the elements.
      The unique elements are guaranteed not to be nulls. So, when 
      reading them from the file we don't have to care about the null
      flags of the read values. However, we should remove the flag 
      at the very beginning of the process. If we don't do it and
      if the last value written into the record buffer for the field
      whose distinct values needs to be counted happens to be null,
      then all values read from the file  are considered to be nulls
      and are not counted in.
      The fix does not remove a possible null flag for the read values.
      Rather it just counts the values in the same way it was done
      before WL #3220.

      Fixed bug mdev-4318. · 21dad7ec
      Igor Babaev authored
      In some cases, when using views the optimizer incorrectly determined
      possible join orders for queries with nested outer and inner joins.
      This could lead to invalid execution plans for such queries.

      Patch by Ian Good for MDEV-4319: mysqlbinlog output ambiguous escaping · c579bce3
      Michael Widenius authored
      The output of mysqlbinlog (with "-v --base64-output=DECODE-ROWS" flags) can not always be read or parsed correctly
      when string columns contain single-quotes or backslash characters.
      
      The fix for this bug is to escape single-quote and backslash characters on output, so that the result is both more
      readable and more easily parse-able.
      
      Note that this is just for comments, so it doesn't affect the replication.
      
      sql/log_event.cc:
        Escape \ and ' properly for mysqlbin user comments.

      MDEV-4252 geometry query crashes server. · 589247ae

          Additional fixes for possible overflows in length-related
          calculations in 'spatial' implementations.
          Checks added to the ::get_data_size() methods.
          max_n_points decreased to occupy less 2G size. An
          object of that size is practically inoperable anyway.

      MDEV-4283 Assertion `scale <= precision' fails in strings/decimal.c · 8f607aae
      Sergei Golubchik authored
        
      with decimals=NOT_FIXED_DEC it is possible to have 'decimals' larger
      than 'max_length', it's not an error for temporal functions.
        
      But when Item_func_numhybrid converts the value to DECIMAL_RESULT,
      it must limit 'decimals' to be a valid scale of a decimal number.
