How to list ALL git objects in the database?

Question

Is there a better way of getting a raw list of SHA1s for ALL objects in a repository than:
ls .git/objects/??/\*
and
cat .git/objects/pack/*.idx | git show-index

I know about git rev-list --all but that only lists commit objects that are referenced by .git/refs, and I'm looking for everything, including unreferenced objects that are created by git-hash-object, git-mktree etc.

Answer 1

Try

 git rev-list --objects --all

Edit Josh made a good point:

 git rev-list --objects -g --no-walk --all

list objects reachable from the ref-logs.

To see all objects in unreachable commits as well:

 git rev-list --objects --no-walk \
      $(git fsck --unreachable |
        grep '^unreachable commit' |
        cut -d' ' -f3)

---

Putting it all together, to really get all objects in the output format of rev-list --objects, you need something like

{
    git rev-list --objects --all
    git rev-list --objects -g --no-walk --all
    git rev-list --objects --no-walk \
        $(git fsck --unreachable |
          grep '^unreachable commit' |
          cut -d' ' -f3)
} | sort | uniq

To sort the output in slightly more useful way (by path for tree/blobs, commits first) use an additional | sort -k2 which will group all different blobs (revisions) for identical paths.
