3897 | ** Overview of algorithm and variables. | |
3898 | ** The array of elements at list1 will be organized into runs of length 2, | |
3899 | ** or runs of length >= 2 * PTHRESH. We only try to form long runs when | |
3900 | ** PTHRESH adjacent pairs compare in the same way, suggesting overall order. | |
3901 | ** | |
3902 | ** Unless otherwise specified, pair pointers address the first of two elements. | |
3903 | ** | |
3904 | ** b and b+1 are a pair that compare with sense ``sense''. | |
3905 | ** b is the ``bottom'' of adjacent pairs that might form a longer run. | |
3906 | ** | |
3907 | ** p2 parallels b in the list2 array, where runs are defined by | |
3908 | ** a pointer chain. | |
3909 | ** | |
3910 | ** t represents the ``top'' of the adjacent pairs that might extend | |
3911 | ** the run beginning at b. Usually, t addresses a pair | |
3912 | ** that compares with opposite sense from (b,b+1). | |
3913 | ** However, it may also address a singleton element at the end of list1, | |
3914 | ** or it may be equal to ``last'', the first element beyond list1. | |
3915 | ** | |
3916 | ** r addresses the Nth pair following b. If this would be beyond t, | |
3917 | ** we back it off to t. Only when r is less than t do we consider the | |
3918 | ** run long enough to consider checking. | |
3919 | ** | |
3920 | ** q addresses a pair such that the pairs at b through q already form a run. | |
3921 | ** Often, q will equal b, indicating we only are sure of the pair itself. | |
3922 | ** However, a search on the previous cycle may have revealed a longer run, | |
3923 | ** so q may be greater than b. | |
3924 | ** | |
3925 | ** p is used to work back from a candidate r, trying to reach q, | |
3926 | ** which would mean b through r would be a run. If we discover such a run, | |
3927 | ** we start q at r and try to push it further towards t. | |
3928 | ** If b through r is NOT a run, we detect the wrong order at (p-1,p). | |
3929 | ** In any event, after the check (if any), we have two main cases. | |
3930 | ** | |
3931 | ** 1) Short run. b <= q < p <= r <= t. | |
3932 | ** b through q is a run (perhaps trivial) | |
3933 | ** q through p are uninteresting pairs | |
3934 | ** p through r is a run | |
3935 | ** | |
3936 | ** 2) Long run. b < r <= q < t. | |
3937 | ** b through q is a run (of length >= 2 * PTHRESH) | |
3938 | ** | |
3939 | ** Note that degenerate cases are not only possible, but likely. | |
3940 | ** For example, if the pair following b compares with opposite sense, | |
3941 | ** then b == q < p == r == t. | |
