Timeline

Count the decoded file set a tree index keeps as the next difference's base toward memoTreeBytes, check a decoded id's gap without wrapping in uint64, and say what cloning the index on publish costs (about 0.5ms for fossil-scm.org's whole history, BenchmarkTreeIndexClone).

TestMemoWideTreesMatchFresh classifies every cone over wide trees that rename, delete and add files, in all three manifest forms, with chains of differences 15 long and with a limit that starts the index again, before and after the store gains check-ins; a branch heads the chains trunk trees continue, so a trunk horizon decodes trees whose chain starts outside its held set. check-in: 7ba1eb6915 user: [email protected] tags: main, perf/memo-tree-encoding, trunk
