508 | * A definition of "relevant" commit that we can use to simplify limited graphs | |
509 | * by eliminating side branches. | |
510 | * | |
511 | * A "relevant" commit is one that is !UNINTERESTING (ie we are including it | |
512 | * in our list), or that is a specified BOTTOM commit. Then after computing | |
513 | * a limited list, during processing we can generally ignore boundary merges | |
514 | * coming from outside the graph, (ie from irrelevant parents), and treat | |
515 | * those merges as if they were single-parent. TREESAME is defined to consider | |
516 | * only relevant parents, if any. If we are TREESAME to our on-graph parents, | |
517 | * we don't care if we were !TREESAME to non-graph parents. | |
518 | * | |
519 | * Treating bottom commits as relevant ensures that a limited graph's | |
520 | * connection to the actual bottom commit is not viewed as a side branch, but | |
521 | * treated as part of the graph. For example: | |
522 | * | |
523 | * ....Z...A---X---o---o---B | |
524 | * . / | |
525 | * W---Y | |
526 | * | |
527 | * When computing "A..B", the A-X connection is at least as important as | |
528 | * Y-X, despite A being flagged UNINTERESTING. | |
529 | * | |
530 | * And when computing --ancestry-path "A..B", the A-X connection is more | |

3032 | * If we are TREESAME to a marked-for-deletion parent, but not to any | |

3034 | * parent that the default simplify_history==1 scan would have followed, | |
3035 | * and it doesn't make sense to omit that path when asking for a | |
3036 | * simplified full history. Retaining it improves the chances of | |
3037 | * understanding odd missed merges that took an old version of a file. | |
3038 | * | |
3039 | * Example: | |
3040 | * | |
3041 | * I--------*X A modified the file, but mainline merge X used | |
3042 | * \ / "-s ours", so took the version from I. X is | |
3043 | * `-*A--' TREESAME to I and !TREESAME to A. | |
3044 | * | |
3045 | * Default log from X would produce "I". Without this check, | |
3046 | * --full-history --simplify-merges would produce "I-A-X", showing | |
3047 | * the merge commit X and that it changed A, but not making clear that | |
3048 | * it had just taken the I version. With this check, the topology above | |
3049 | * is retained. | |
3050 | * | |
3051 | * Note that it is possible that the simplification chooses a different | |
3052 | * TREESAME parent from the default, in which case this test doesn't | |
3053 | * activate, and we _do_ drop the default parent. Example: | |
3054 | * | |
3055 | * I------X A modified the file, but it was reverted in B, | |
3056 | * \ / meaning mainline merge X is TREESAME to both | |
3057 | * *A-*B parents. | |
3058 | * | |
3059 | * Default log would produce "I" by following the first parent; | |
3060 | * --full-history --simplify-merges will produce "I-A-B". But this is a | |
3061 | * reasonable result - it presents a logical full history leading from | |
3062 | * I to X, and X is not an important merge. | |
