519 | * A definition of "relevant" commit that we can use to simplify limited graphs | |
520 | * by eliminating side branches. | |
521 | * | |
522 | * A "relevant" commit is one that is !UNINTERESTING (ie we are including it | |
523 | * in our list), or that is a specified BOTTOM commit. Then after computing | |
524 | * a limited list, during processing we can generally ignore boundary merges | |
525 | * coming from outside the graph, (ie from irrelevant parents), and treat | |
526 | * those merges as if they were single-parent. TREESAME is defined to consider | |
527 | * only relevant parents, if any. If we are TREESAME to our on-graph parents, | |
528 | * we don't care if we were !TREESAME to non-graph parents. | |
529 | * | |
530 | * Treating bottom commits as relevant ensures that a limited graph's | |
531 | * connection to the actual bottom commit is not viewed as a side branch, but | |
532 | * treated as part of the graph. For example: | |
533 | * | |
534 | * ....Z...A---X---o---o---B | |
535 | * . / | |
536 | * W---Y | |
537 | * | |
538 | * When computing "A..B", the A-X connection is at least as important as | |
539 | * Y-X, despite A being flagged UNINTERESTING. | |
540 | * | |
541 | * And when computing --ancestry-path "A..B", the A-X connection is more | |
