Using a git bundle to fetch the I2P source code
Cloning large software repositories over I2P can be difficult, and using git can sometimes make this harder. Fortunately, it can also sometimes make it easier. Git has a
git bundle command which can be used to turn a git repository into a file which git can then clone, fetch, or import from a location on your local disk. By combining this capability with bittorrent downloads, we can solve our remaining problems with
Before you Start
If you intend to generate a git bundle, you must already possess a full copy of the git repository, not the mtn repository. You can get it from github or from git.idk.i2p, but a shallow clone(a clone done to –depth=1) will not work. It will fail silently, creating what looks like a bundle, but when you try to clone it it will fail. If you are just retrieving a pre-generated git bundle, then this section does not apply to you.
Fetching I2P Source via Bittorrent
Someone will need to supply you with a torrent file or a magnet link corresponding to an existing
git bundle that they have already generated for you. A recent, correctly-generated bundle of the mainline i2p.i2p source code as-of Wednesday, March 18, 2020, can be found inside of I2P at my pastebin paste.idk.i2p/f/4hq37i.
Once you have a bundle, you will need to use git to create a working repository from it. If you’re using GNU/Linux and i2psnark, the git bundle should be located in $HOME/.i2p/i2psnark or, as a service on Debian, /var/lib/i2p/i2p-config/i2psnark. If you are using BiglyBT on GNU/Linux, it is probably at “$HOME/BiglyBT Downloads/” instead. The examples here assume I2PSnark on GNU/Linux, if you use something else, replace the path to the bundle with the download directory preferred by your client and platform.
Cloning from a git bundle is easy, just:
git clone $HOME/.i2p/i2psnark/i2p.i2p.bundle
If you get the following error, try using git init and git fetch manually instead.
fatal: multiple updates for ref 'refs/remotes/origin/master' not allowed
git init and
First, create an i2p.i2p directory to turn into a git repository.
mkdir i2p.i2p && cd i2p.i2p
Next, initialize an empty git repository to fetch changes back into.
Finally, fetch the repository from the bundle.
git fetch $HOME/.i2p/i2psnark/i2p.i2p.bundle
Replace the bundle remote with the upstream remote
Now that you have a bundle, you can keep up with changes by setting the remote to the upstream repository source.
git remote set-url origin firstname.lastname@example.org:i2p-hackers/i2p.i2p
Generating a Bundle
First, follow the Git guide for Users until you have a successfully
--unshallowed clone of clone of the i2p.i2p repository. If you already have a clone, make sure you run
git fetch --unshallow before you generate a torrent bundle.
Once you have that, simply run the corresponding ant target:
and copy the resulting bundle into your I2PSnark downloads directory. For instance:
cp i2p.i2p.bundle* $HOME/.i2p/i2psnark/
In a minute or two, I2PSnark will pick up on the torrent. Click on the “Start” button to begin seeding the torrent.
