6 | # We want to create a situation where the shallow, grafted | |
7 | # view of reachability does not match reality in a way that | |
8 | # might cause us to send insufficient objects. | |
9 | # | |
10 | # We do this with a history that repeats a state, like: | |
11 | # | |
12 | # A -- B -- C | |
13 | # file=1 file=2 file=1 | |
14 | # | |
15 | # and then create a shallow clone to the second commit, B. | |
16 | # In a non-shallow clone, that would mean we already have | |
17 | # the tree for A. But in a shallow one, we've grafted away | |
18 | # A, and fetching A to B requires that the other side send | |
19 | # us the tree for file=1. | |
