| 8869 | * build_node could be forced into stack exhaustion from input as small as a |
| 8870 | * few megabyte, and so that was a security issue. Hence, a function call |
| 8871 | * stack is avoided now by resolving recursion.) |
| 8872 | * |
| 8873 | * The iterative approach works as follows: |
| 8874 | * |
| 8875 | * - We have two writing pointers, both walking up the result array; one does |
| 8876 | * the work, the other creates "jobs" for its colleague to do, and leads |
| 8877 | * the way: |
| 8878 | * |
| 8879 | * - The faster one, pointer jobDest, always leads and writes "what job |
| 8880 | * to do" by the other, once they reach that place in the |
| 8881 | * array: leader "jobDest" stores the source node array index (relative |
| 8882 | * to array dtd->scaffold) in field "numchildren". |
| 8883 | * |
| 8884 | * - The slower one, pointer dest, looks at the value stored in the |
| 8885 | * "numchildren" field (which actually holds a source node array index |
| 8886 | * at that time) and puts the real data from dtd->scaffold in. |
| 8887 | * |
| 8888 | * - Before the loop starts, jobDest writes source array index 0 |
| 8889 | * (where the root node is located) so that dest will have something to do |
| 8890 | * when it starts operation. |
| 8891 | * |
| 8892 | * - Whenever nodes with children are encountered, jobDest appends |
| 8893 | * them as new jobs, in order. As a result, tree node siblings are |
| 8894 | * adjacent in the resulting array, for example: |
| 8895 | * |
| 8896 | * [0] root, has two children |
| 8897 | * [1] first child of 0, has three children |
| 8898 | * [3] first child of 1, does not have children |
| 8899 | * [4] second child of 1, does not have children |
| 8900 | * [5] third child of 1, does not have children |
| 8901 | * [2] second child of 0, does not have children |
| 8902 | * |
| 8903 | * Or (the same data) presented in flat array view: |
| 8904 | * |
| 8905 | * [0] root, has two children |
| 8906 | * |
| 8907 | * [1] first child of 0, has three children |
| 8908 | * [2] second child of 0, does not have children |
| 8909 | * |
| 8910 | * [3] first child of 1, does not have children |
| 8911 | * [4] second child of 1, does not have children |
| 8912 | * [5] third child of 1, does not have children |
| 8913 | * |
| 8914 | * - The algorithm repeats until all target array indices have been processed. |
