Recovering Git repository from objects only

问题:

I have a Windows box which has taken it into it's head to delete most of a Git repository (must have tripped the Important Work Detector ;). All I have left (that I can find) is the objects. I'm not sure how complete the collection of objects is, either. Is it possible to recover things from just the objects? As far as I can tell, the object tree is intact. All the packs and loose objects are in place; I just don't have the metadata to convince Git.

回答1:

The first thing that I would try is to initialize a new repository with git init. Then I'd copy the objects directory from the dead repository into the new repository. Then I'd run git fsck in the new repository.

With some luck you'll see a whole lot of dangling objects and with a bit more luck some of the dangling objects will be commit objects which will be the tips of lost branches.

If you run git show and/or git log on these commits you may be able to recognize some of the branches.

To "recover" them you can just use git branch to recreate named branches.

回答2:

If you haven't already tried git checkout master, I'd start with that.
