How to recover .git folder from data recovery software?

Question

I accidentally deleted all files including .git folder by using shift+delete.

I managed to recover them using a data recovery software. However, the directory is unable to work.

The error message is as follows:

$ git fsck --full

fatal: index file corrupt

I am not sure if all files have been recovered, but I assume they do since the directory structure looks like a normal git folder.

I want to recover as much as possible, especially my local branches which are not submitted to remote yet.

Please help!

Answer 1

1. Make a copy of the repository at the current state from how you recovered from the data recovery software, so you can at least go back to a backup

2. Check if you have got the whole of your repository in the folder structure, before you accidentally deleted the repository.

You could try the following commands, and remove the corrupted objects, but objects are your data files, but see what the output is, from the following webpage, https://itqna.net/questions/1935/git-fetch-inflate-data-stream-error-and-sha1-collision-found

Removal of corrupted references :

$ rm rm .git/refs/remotes/origin/hotfix-{branch-1}
garbage collection / garbage collector aggressive to collect all corrupted objects

:
$ git gc --aggressive
Check if everything is functional, just in case?

$ git fsck --full

The information below was taken from the following page and should be really useful for you and for you to learn about the .git folder as well.

https://git.seveas.net/repairing-and-recovering-broken-git-repositories.html

Repairing and recovering broken git repositories

Whether it's filesystem corruption due to a power outage, an overactive virus scanner, or a simple slip of the keyboard, it is not uncommon to hear about corruption inside the .git directory. It is much rarer to hear about such corruption being caused by git. I personally have never seen it, and it would surely be considered a critical bug if it were to happen.

So, what can we remove while still having something to recover? Well, pretty much everything except the objects directory. And even if you remove files from there, all other objects will be recoverable.

Make backups and try in a copy first

Your repository is already broken. Don't break it any further without first making sure nobody can access it except you, making a backup (tar, rsync) of the repository and first trying the commands in a copy of the repository.

$ tar zcvf myrepo.tar.gz myrepo
$ rsync -av myrepo/ myrepo-copy/
$ cd myrepo-copy/

All the files in .git are gone!

One of the more interesting (and surprisingly easy to solve!) cases of corruption I've seen is someone losing all the files in the .git directory, but no directories or files inside those directories were lost. We never did find out how it happened, but it was surprisingly easy to fix this.

The gitrepository-layout manpage can tell you which files git expects to exist.

Below you find out how to restore them when they've gone missing.

HEAD

When .git/HEAD is gone, git doesn't even think your repository is a repository. So really, we must fix this first or else we will not be able to use any git commands to salvage the rest.

$ rm .git/HEAD
$ git status
fatal: Not a git repository (or any of the parent directories): `.git`

This is one of the very few times where touching files inside .git is OK.
If you know which branch you had checked out, you can simply put that information inside .git/HEAD.
I had the master branch checked out before deleting the HEAD file.

$ echo 'ref: refs/heads/master' > .git/HEAD
$ git status

On branch master
Your branch is up-to-date with 'origin/master'.
nothing to commit, working directory clean

If you don't know which branch (or even commit in detached HEAD state) you had checked out, try a few.
If you picked the wrong one, git diff will tell you that there are many uncommitted changes.

index

Should you misplace your index, git thinks that all your files have been deleted from the repository with git rm --cached.

$ rm .git/index
$ git status
On branch master
Your branch is up-to-date with 'origin/master'.
Changes to be committed:
  (use "git reset HEAD <file>..." to unstage)

    deleted:    .gitignore
    deleted:    docs/index.rst
    deleted:    setup.py

Untracked files:
  (use "git add <file>..." to include in what will be committed)

    .gitignore
    docs/
    setup.py

To rebuild the index, you can simply do git reset --mixed.
This makes the index look like the last commit while leaving the worktree alone.
If you had any local changes you git added but did not commit yet, you will need to re-add those.

$ git reset --mixed
$ git status

On branch master
Your branch is up-to-date with 'origin/master'.
nothing to commit, working directory clean config

When the configuration is gone, you can't really get it back.
But you can set the default configuration variables and re-add your remotes.
This should get you into a workable state. So let's first do the default configuration.

$ git init

Git's init command will create a configuration if none exists. It will not wipe any objects, so it's safe to run in an existing repository.
If your repository was a shared repository, you will need to tell git that manually though, using git config core.sharedRepository true.

With the configuration in place, we can re-add our remotes.
My corrupt repository has one remote that lives on GitHub, so I'll add it.

$ git remote add origin git@github.com:seveas/whelk.git
$ git fetch

Are we done? Almost!

git branch -avv will tell you that your branches are no longer tracking their remote counterparts.
If you have only a master branch, a simple git branch -u origin/master master is enough to set up tracking.
If you have many branches, you will want to script this.

for head in $(git for-each-ref --format '%(refname:short)' refs/heads); do
    if git rev-parse -q --verify origin/$head >/dev/null; then
        git branch -u origin/$head $head
    fi
done
packed-refs

If the packed-refs file is gone, you might have lost an awful lot of refs.
Try a git fetch to see if some of them come back (tags and remote refs).
For local refs, see the recipe below that discusses losing the refs directory.

A folder in .git is gone!

Not even two weeks after the case of the missing files, a user popped into #git who had lost everything except .git/objects/ (seriously, how do people do this?!).
We managed to recreate everything else, which was of course made easier because he had only a single remote and a single branch. But it just goes to show that you can lose a lot of things and still keep git happy.

In this case it is important though to recover things in the correct order. The order we used was:

HEAD
refs/
HEAD again and index
config
refs

The refs directory contains all your branches, tags and other refs, except for the ones stored in .git/packed-refs.
When you lose refs, there are a few strategies to get them back.
The simplest one is to fetch from a remote repository (if you have any). This will bring back refs in refs/remotes, and tags that the remote has.
When you lost all refs, you will first need to manually mkdir -p .git/refs/heads to get git to recognize the repository at all.

For local refs, there are two locations where you can recover the previous values of refs :

• the reflog and
• the output of fsck.

If you still have your reflogs, you will find the correct value of a ref to on the last line of its reflog.
Here's an example of recovering the master branch:

$ tail -n1 .git/logs/refs/heads/master
54bc41416c5d3ecb978acb0df80d57aa3e54494c 2c78628255b8cc7f0b5d47981acea138db8716d2

$ git update-ref refs/heads/master 2c78628255b8cc7f0b5d47981acea138db8716d2

The reflog in .git/logs/HEAD can show you which branch you had last checked out. This can help you update the HEAD ref.

$ tail -n1 .git/logs/HEAD
7f79f6a992b11aaaf2592075346d83b1ba0f4ff8 a5e28dbe709a544f51b9c44752e14e5cd007a815 Dennis Kaarsemaker <dennis@kaarsemaker.net> 1448810920 +0100  checkout: moving from 7f79f6a992b11aaaf2592075346d83b1ba0f4ff8 to master
$ git symbolic-ref HEAD refs/heads/master

If you do not have any reflogs, you can still recover refs by looking at your commit objects. If a commit has no descendants, it could be at the tip of a branch, so a ref should point to it.
It could also be a commit that was amended, rebased or simply discarded, so this method may give you some false positives to sort through.

So how do you find commits without descendants? Fortunately you don't need to do this manually, git fsck is here to help. Let's break a simple repository to show it.

$ git clone https://github.com/seveas/whelk.git

These dangling commits are the tips of the branches. But which one is which? There's no way to know without looking, so let's create some temporary branches and have a look

$ git update-ref refs/heads/recovery-1 aa7856977e80d11833e97b4151f400a516316179
$ git update-ref refs/heads/recovery-2 16e449da82ec8bb51aed56c0c4c05473442db90a
$ git update-ref refs/heads/recovery-3 864c345397fcb3bdb902402e17148e19b3f263a8
$ git log --graph --all --oneline --decorate

In the resulting log, you'll see where these temporary branches point, and you can use git branch -m to give them their correct names back. And those dangling tags? Those are tag objects that you can now recover, the tag object even has the tag name in it!

$ git cat-file tag be9471e1263a78fd765d4c72925c0425c90d3d64

logs

If the reflogs are gone, they cannot be recovered.
Fortunately, these logs aren't necessary for the normal operation of git and losing them only makes recovering refs harder.

objects

If the objects directory is gone, it's time to give up.
This is where your data lives, and with it gone, what's left is useless. If you still have your worktree, you can use it to start a new repository.
Delete the .git directory and git init to start over.

If the directory is not gone completely, but you have some corrupt or missing objects, see below for tips and tricks on how to recover from this

info

The info/ directory is mostly useless these days, as it is only used for the obsolete dumb http protocol.
If you still use this protocol and lost the info/ directory of the repository that is being pulled from, you can recreate it with git update-server-info.

modules

If the modules directory is gone, Git can get quite upset.
To fix this, move the submodules' worktrees out of the way (or delete them if you're sure you have no changes) and simply run git submodule update to reclone them.
Then put your worktrees back if you had local changes, and you can commit those.

worktrees

A feature still under heavy development is support for multiple worktrees for a single repository. Information about these worktrees is stored in the worktrees directory.

For each worktree, there is a separate directory containing at least HEAD, index, logs/HEAD, gitdir and commondir.

• HEAD, index and logs/HEAD can be recovered as above.
• gitdir should contain the path to the .git file inside the separate worktree and
• commondir should contain the path to the original .git dir of the repository, usually ../..

Object corruption

The worst kind of corruption in a git repository is corrupt or missing objects. Corrupt objects are incredibly tricky to recover if you do not have a copy of them, so we will focus on restoring missing objects from another copy of the repository so any local-only work is not lost.

So let's first find out which objects are corrupt and remove them (you did read the first section of this article, saying to try this first in a copy of the repository, right?).

$ git fsck --full

This repository was intentionally broken by modifying some files with a hex editor. git fsck detects this and tells you which files have been tampered with. Any corrupt loose objects can simply be removed, but corrupt packfiles probably also contain some recoverable objects, so we try to recover those before removing the file.

$ mv .git/objects/pack/pack-0672bd01813664b80248dbe8330bf52da9c02b9f.pack .
$ git unpack-objects -r < pack-0672bd01813664b80248dbe8330bf52da9c02b9f.pack
$ rm pack-0672bd01813664b80248dbe8330bf52da9c02b9f.pack
$ rm .git/objects/27/c221b1620b8414de002b00aa990fd8e0d768a7

With those files now out of the way, git fsck will report all missing objects. We can try recovering those from a fresh clone.

$ git unpack-objects < ../fresh-clone/.git/objects/pack/pack-*.pack

If there are still missing objects, you can try adding the current contents of the work directory to your repository:

$ find -type f -print0 | xargs -0 git hash-object -w
