I have lost the commit object in a corrupt repository, but there are still some files and the tree object:
$ git fsck
Checking object directories: 100% (256/256), done.
dangling blob 031be26142ed97da216fb7d79d16a0b0efdf0d71

Is there a way to check out that tree object?
I guess there could be a way to rebuild the commit object with a dummy commit string and check that out.
git cat-file -p tree-sha1
If you git checkout 4b825dc642cb6eb9a060e54bf8d69288fbee4904 .
(the dot for a path name is important, otherwise git will interpret it as a branch switch operation and refuse) it will update all of the files in both the working directory and the index to match the state of 4b825d... (that is, git diff
will show nothing, git diff --staged
will show a lot of changes, and git status
will show a lot of M). You can inspect the state of the files that way.
If you have a guess at a relevant parent commit, you can
git checkout -b recover relevant_parent
git checkout 4b825dc642cb6eb9a060e54bf8d69288fbee4904 .
git commit -m "Recovered this thing that git fsck told me about"
to give it a commit and a branch to address it by.
