git-fastclone

git-fastclone is git clone --recursive on steroids.

Why fastclone?

Doing lots of repeated checkouts on a specific machine?

Above times captured using time without verbose mode.

What does it do?

It creates a reference repo with git clone --mirror in /var/tmp/git-fastclone/reference for each repository and git submodule linked in the main repo. You can control where it puts these by changing the REFERENCE_REPO_DIR environment variable.

It aggressively updates these mirrors from origin and then clones from the mirrors into the directory of your choosing. It always works recursively and multithreaded to get your checkout up as fast as possible.

Detailed explanation here.

Usage

gem install git-fastclone
git fastclone [options] <git-repo-url>

-b, --branch <branch>   Clone a specific branch
-v, --verbose           Shows more info
-c, --color             Pretty colors!

Change the default REFERENCE_REPO_DIR environment variable if necessary.

Cygwin users need to add ~/bin to PATH.

How to test?

Manual testing:

ruby -Ilib bin/git-fastclone <git url>

Compatible with Travis and Kochiku.
