3858 | ** Overview of algorithm and variables. | |
3859 | ** The array of elements at list1 will be organized into runs of length 2, | |
3860 | ** or runs of length >= 2 * PTHRESH. We only try to form long runs when | |
3861 | ** PTHRESH adjacent pairs compare in the same way, suggesting overall order. | |
3862 | ** | |
3863 | ** Unless otherwise specified, pair pointers address the first of two elements. | |
3864 | ** | |
3865 | ** b and b+1 are a pair that compare with sense ``sense''. | |
3866 | ** b is the ``bottom'' of adjacent pairs that might form a longer run. | |
3867 | ** | |
3868 | ** p2 parallels b in the list2 array, where runs are defined by | |
3869 | ** a pointer chain. | |
3870 | ** | |
3871 | ** t represents the ``top'' of the adjacent pairs that might extend | |
3872 | ** the run beginning at b. Usually, t addresses a pair | |
3873 | ** that compares with opposite sense from (b,b+1). | |
3874 | ** However, it may also address a singleton element at the end of list1, | |
3875 | ** or it may be equal to ``last'', the first element beyond list1. | |
3876 | ** | |
3877 | ** r addresses the Nth pair following b. If this would be beyond t, | |
3878 | ** we back it off to t. Only when r is less than t do we consider the | |
3879 | ** run long enough to consider checking. | |
3880 | ** | |
3881 | ** q addresses a pair such that the pairs at b through q already form a run. | |
3882 | ** Often, q will equal b, indicating we only are sure of the pair itself. | |
3883 | ** However, a search on the previous cycle may have revealed a longer run, | |
3884 | ** so q may be greater than b. | |
3885 | ** | |
3886 | ** p is used to work back from a candidate r, trying to reach q, | |
3887 | ** which would mean b through r would be a run. If we discover such a run, | |
3888 | ** we start q at r and try to push it further towards t. | |
3889 | ** If b through r is NOT a run, we detect the wrong order at (p-1,p). | |
3890 | ** In any event, after the check (if any), we have two main cases. | |
3891 | ** | |
3892 | ** 1) Short run. b <= q < p <= r <= t. | |
3893 | ** b through q is a run (perhaps trivial) | |
3894 | ** q through p are uninteresting pairs | |
3895 | ** p through r is a run | |
3896 | ** | |
3897 | ** 2) Long run. b < r <= q < t. | |
3898 | ** b through q is a run (of length >= 2 * PTHRESH) | |
3899 | ** | |
3900 | ** Note that degenerate cases are not only possible, but likely. | |
3901 | ** For example, if the pair following b compares with opposite sense, | |
3902 | ** then b == q < p == r == t. | |
