/**
Combine two range expression under a common OR. On a logical level, the
transformation is key_or( expr1, expr2 ) => expr1 OR expr2.
Both expressions are assumed to be in the SEL_ARG format. In a logic sense,
theformat is reminiscent of DNF, since an expression such as the following
( 1 < kp1 < 10 AND p1 ) OR ( 10 <= kp2 < 20 AND p2 )
where there is a key consisting of keyparts ( kp1, kp2, ..., kpn ) and p1
and p2 are valid SEL_ARG expressions over keyparts kp2 ... kpn, is a valid
SEL_ARG condition. The disjuncts appear ordered by the minimum endpoint of
the first range and ranges must not overlap. It follows that they are also
ordered by maximum endpoints. Thus
( 1 < kp1 <= 2 AND ( kp2 = 2 OR kp2 = 3 ) ) OR kp1 = 3
Is a a valid SER_ARG expression for a key of at least 2 keyparts.
For simplicity, we will assume that expr2 is a single range predicate,
i.e. on the form ( a < x < b AND ... ). It is easy to generalize to a
disjunction of several predicates by subsequently call key_or for each
disjunct.
The algorithm iterates over each disjunct of expr1, and for each disjunct
where the first keypart's range overlaps with the first keypart's range in
expr2:
If the predicates are equal for the rest of the keyparts, or if there are
no more, the range in expr2 has its endpoints copied in, and the SEL_ARG
node in expr2 is deallocated. If more ranges became connected in expr1, the
surplus is also dealocated. If they differ, two ranges are created.
- The range leading up to the overlap. Empty if endpoints are equal.
- The overlapping sub-range. May be the entire range if they are equal.
Finally, there may be one more range if expr2's first keypart's range has a
greater maximum endpoint than the last range in expr1.
For the overlapping sub-range, we recursively call key_or. Thus in order to
compute key_or of
(1) ( 1 < kp1 < 10 AND 1 < kp2 < 10 )
(2) ( 2 < kp1 < 20 AND 4 < kp2 < 20 )
We create the ranges 1 < kp <= 2, 2 < kp1 < 10, 10 <= kp1 < 20. For the
first one, we simply hook on the condition for the second keypart from (1)
: 1 < kp2 < 10. For the second range 2 < kp1 < 10, key_or( 1 < kp2 < 10, 4
< kp2 < 20 ) is called, yielding 1 < kp2 < 20. For the last range, we reuse
the range 4 < kp2 < 20 from (2) for the second keypart. The result is thus
( 1 < kp1 <= 2 AND 1 < kp2 < 10 ) OR
( 2 < kp1 < 10 AND 1 < kp2 < 20 ) OR
( 10 <= kp1 < 20 AND 4 < kp2 < 20 )
