gitバンドルを使ったI2Pソースコードの取得

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 git clone.

始める前に

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.

I2PソースをBitTorrent経由で取得

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.

Using git clone

gitバンドルからのクローンは簡単です。単に：

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

Using git init and git fetch

まず gitレポジトリとするためのi2p.i2pディレクトリを作成します。

mkdir i2p.i2p && cd i2p.i2p

次に、更新取得にむけて空のgitレポジトリを初期化します。

git init

最後に、バンドルからレポジトリを取得します。

git fetch $HOME/.i2p/i2psnark/i2p.i2p.bundle

バンドルリモートを上流リモートで置き換える

バンドルを持っている今、リモートを上流レポジトリソースに設定することで更新に追従できます。

git remote set-url origin git@127.0.0.1:i2p-hackers/i2p.i2p

バンドルの生成

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.

取得できたら、対応するant targetを走らせるだけです：

ant git-bundle

and copy the resulting bundle into your I2PSnark downloads directory. For instance:

cp i2p.i2p.bundle* $HOME/.i2p/i2psnark/

数分でI2PSnarkがそのトレントを拾います。 「開始」ボタンをクリックし、torrentのシードを始めてください。
