     This function aggregates result types from the array of items. Found type
     supposed to be used later for comparison of values of these items.
     Aggregation itself is performed by the item_cmp_type() function.
-
-  NOTES
-    Aggregation rules:
-    If there are DATE/TIME fields/functions in the list and no string
-    fields/functions in the list then:
-      The INT_RESULT type will be used for aggregation instead of original
-      result type of any DATE/TIME field/function in the list
-      All constant items in the list will be converted to a DATE/TIME using
-      found field or result field of found function.
-
-    Implementation notes:
-      The code is equivalent to:
-      1. Check the list for presence of a STRING field/function.
-         Collect the is_const flag.
-      2. Get a Field* object to use for type coercion
-      3. Perform type conversion.
-      1 and 2 are implemented in 2 loops. The first searches for a DATE/TIME
-      field/function and checks presence of a STRING field/function.
-      The second loop works only if a DATE/TIME field/function is found.
-      It checks presence of a STRING field/function in the rest of the list.
-
-  TODO
-    1) The current implementation can produce false comparison results for
-    expressions like:
-      date_time_field BETWEEN string_field_with_dates AND string_constant
-    if the string_constant will omit some of leading zeroes.
-    In order to fully implement correct comparison of DATE/TIME the new
-    DATETIME_RESULT result type should be introduced and agg_cmp_type()
-    should return the DATE/TIME field used for the conversion. Later
-    this field can be used by comparison functions like Item_func_between to
-    convert string values to ints on the fly and thus return correct results.
-    This modification will affect functions BETWEEN, IN and CASE.
-
-    2) If in the list a DATE field/function and a DATETIME field/function
-    are present in the list then the first found field/function will be
-    used for conversion. This may lead to wrong results and probably should
-    be fixed.

+  
+  DESCRIPTION
+    The passed WHERE and HAVING are to be saved for the future executions.
+    This function saves it, and returns a copy which can be thrashed during
+    this execution of the statement. By saving/thrashing here we mean only
+    AND/OR trees.
+    The function also calls fix_prepare_info_in_table_list that saves all

+      cond_equal  multiple equalities that must hold together with the equality
 
   DESCRIPTION
-    This function first checks whether an item is a simple equality i.e.
-    the one that equates a field with another field or a constant
-    (item=constant_item or item=field_item).
-    If this is the case the function looks a for a multiple equality
+    This function first checks whether the equality (left_item=right_item)
+    is a simple equality i.e. the one that equates a field with another field
+    or a constant (field=field_item or field=const_item).
+    If this is the case the function looks for a multiple equality
     in the lists referenced directly or indirectly by cond_equal inferring
     the given simple equality. If it doesn't find any, it builds a multiple
     equality that covers the predicate, i.e. the predicate can be inferred
-    from it.
+    from this multiple equality.
     The built multiple equality could be obtained in such a way:
     create a binary  multiple equality equivalent to the predicate, then
     merge it, if possible, with one of old multiple equalities.
     This guarantees that the set of multiple equalities covering equality
-    predicates will

+
+  DESCRIPTION
+    This function checks whether the item is a simple equality
+    i.e. the one that equates a field with another field or a constant
+    (field=field_item or field=constant_item), or, a row equality.
+    For a simple equality the function looks for a multiple equality
+    in the lists referenced directly or indirectly by cond_equal inferring
+    the given simple equality. If it doesn't find any, it builds/expands
+    multiple equality that covers the predicate.
+    Row equalities are eliminated substituted for conjunctive regular equalities
+    which are treated in the same way as original equality predicates.
+
+  RETURN
+    TRUE   if re-writing rules have been applied
+    FALSE  otherwise, i.e.
+           if the predicate is not an equality,
+           or, if the equality is neither a simple one nor a row equality,
+           or, if the procedure fails by a fatal error.
