Overall, this round is looking really good, though there are a couple things I called out in comments on individual patches that I'll summarize here: Patch 9: a few minor suggestions for improving comments Patch 10: the new code is never triggered and probably should either be dropped or made part of a later series if the later series needs it. Also, although it doesn't necessarily need to hold up this series, I found a bug affecting sparse-checkouts with or without sparse-index while trying to understand this patch. Patch 12: the code was slightly confusing to me, but I found that there seems to be an invariant it is based upon. Adding an assert with a comment or just a comment about this invariant might help make the code more readable. Patch 15: since the new tests in t1092 are written to compare sparse-checkout and sparse-index, it seems we should investigate a bug where the testsuite commands we invoke are giving incorrect behavior in both sparse-checkout and sparse-index.
