still reducing the number of binary searches required for object
lookups.
-- The reachability bitmap is currently paired directly with a single
- packfile, using the pack-order as the object order to hopefully
- compress the bitmaps well using run-length encoding. This could be
- extended to pair a reachability bitmap with a multi-pack-index. If
- the multi-pack-index is extended to store a "stable object order"
+- If the multi-pack-index is extended to store a "stable object order"
(a function Order(hash) = integer that is constant for a given hash,
- even as the multi-pack-index is updated) then a reachability bitmap
- could point to a multi-pack-index and be updated independently.
+ even as the multi-pack-index is updated) then MIDX bitmaps could be
+ updated independently of the MIDX.
- Packfiles can be marked as "special" using empty files that share
the initial name but replace ".pack" with ".keep" or ".promisor".
