Disclaimer

Use this software at your own risk!

You should know that if the repository you are downloading is controlled by an attacker, this could lead to remote code execution on your machine.

Build from source

Simply install the dependencies with pip:

pip install -r requirements.txt

Then, simply use:

./git_dumper.py http://website.com/.git ~/website

How does it work?

The tool will first check if directory listing is available. If it is, then it will just recursively download the .git directory (what you would do with wget).

If directory listing is not available, it will use several methods to find as many files as possible. Step by step, git-dumper will:

  • Fetch all common files (.gitignore, .git/HEAD, .git/index, etc.);
  • Find as many refs as possible (such as refs/heads/master, refs/remotes/origin/HEAD, etc.) by analyzing .git/HEAD, .git/logs/HEAD, .git/config, .git/packed-refs and so on;
  • Find as many objects (sha1) as possible by analyzing .git/packed-refs, .git/index, .git/refs/* and .git/logs/*;
  • Fetch all objects recursively, analyzing each commits to find their parents;
  • Run git checkout . to recover the current working tree
