Is there currently any way in the code base that a complete sub-directory can be marked as 'missing' as could be the case for a narrow clone? The assume-unchanged/skip-worktree are close but only applies to filepaths/blobs, rather than trees. At the moment 'Cached tree' index extension does list the sha1 for unchanged sub-drectories for ease of creating tree's for new commits, but I couldn't see if it could be (ab)used to support a narrow clone. Have there been previous attempts to look at marking sub-dirs as --skip-worktree, or some other sentinel value for the missing tree? --- Philip Oakley ``` ## Duy Nguyen, 2014-02-27 23:26 Subject: Re: How to mark a complete sub-directory assume-unchanged/skip-worktree?

I dealt with this by creating partial index, that only contains entries for interested subtrees. The index also stores the base tree SHA-1, so write-tree can still create (full) new trees correctly from partial index. -- Duy ``` ## Philip Oakley, 2014-02-27 23:38 Subject: Re: How to mark a complete sub-directory assume-unchanged/skip-worktree?

My last attempt was http://git.661346.n2.nabble.com/PATCH-00-17-Narrow-clone-v3-was-subtree-clone-tt5499879.html If you're interested in the index part then see 15/17 and maybe 03/17 and 04/17. I can try to rebase and publish the series somewhere if you want to try it out. -- Duy ``` ## Philip Oakley, 2014-02-28 08:37 Subject: Re: How to mark a complete sub-directory assume-unchanged/skip-worktree?

I'll look it out and see how well it matched my ideas, and reflect on any differences to pick up learning points early! Philip ```
