I don't think there is a way. We probably should improve ls-files and
update-index to examine and update basically everything in the index..
But so far, nothing yet.

Yeah. I see libgit2 has a haskell binding, probably best for you.

update index mtime etc metadata

[Joey Hess]

Is there any available plumbing that can change the mtime etc metadata
that is recorded in the index for a file, to user-provided values? Or,
to force the current file stat metadata to be updated in the index?

I know, git update-index --refresh, but I have a case where that's too
expensive. I'm using smudge filters; I know that the cleaned version of
the file will be unchanged from what's in the index now and only the
stat metadata will change, and so I want to avoid
git update-index --refresh running the clean filter, which can
be quite expensive for a large file.

At the moment I don't see a way to do it other than using eg libgit2 to
update the appropriate fields in the index structure.
