| // 2. Null-build (x z), so we don't evaluate or dirty anything, but because we know there was |
| // some conflict last time but don't know exactly which targets conflicted, it could have |

| // set, and record the fact that there were bad actions. |
| // 2. Null-build (x z), so we don't evaluate or dirty anything, but we check again for |
| // conflict because foundActionConflictInLatestCheck is true, and store (x z) as the |
| // largest checked key set. |
| // 3. Null-build (y z), so again we don't evaluate or dirty anything, and the previous build |
| // had no conflicts, so no other condition is true. But because (y z) is not a subset of |
| // (x z) and we only keep the most recent largest checked key set, we don't know if (y z) |
| // are conflict free, so we check. |

| // We believe the conditions above are correct in the sense that we always check for conflicts |
| // when we have to. But they are incomplete, so we sometimes check for conflicts even if we |
| // wouldn't have to. For example: |
| // - if no target was evaluated nor dirtied and build sequence is (x y) [no conflict], (z), |
| // where z is in the transitive closure of (x y), then we shouldn't check. |
| // - if no target was evaluated nor dirtied and build sequence is (x y) [no conflict], (w), (x), |
| // then the last build shouldn't conflict-check because (x y) was checked earlier. But it |
| // does, because after the second build we store (w) as the largest checked set, and (x) is |
| // not a subset of that. |
| |
| // Case when we DON'T need to re-check: |
| // - a configured target is deleted. Deletion can only resolve conflicts, not introduce any, and |
| // if the previous build had a conflict then foundActionConflictInLatestCheck would be true, |
| // and if the previous build had no conflict then deleting a CT won't change that. |
| // Example that triggers this scenario: |
| // 1. genrule(name='x', srcs=['A'], ...) |
| // genrule(name='y', outs=['A'], ...) |
| // 2. Build (x y) |
| // 3. Rename 'x' to 'y', and 'y' to 'z' |
| // 4. Build (y z) |
| // 5. Null-build (y z) again |
| // We only delete the old 'x' value in (5), and we don't evaluate nor dirty anything, nor was |
| // (4) bad. So there's no reason to re-check just because we deleted something. |
