We use Git for managing the IPFire source code and the source code of all our other smaller projects.
You can browse the source code on http://git.ipfire.org/ or alternatively http://cgit.ipfire.org/. It is freely downloadable via the Git protocol, HTTP or SSH. The URLs to the repositories can be found on their respective summary pages.
IPFire uses two repositories for two major versions.
The master branch holds the code that is currently shipped.
git clone git://git.ipfire.org/ipfire-2.x.git
The next branch is the development branch that will eventually become the next Core Update.
git clone git://git.ipfire.org/ipfire-2.x.git git checkout -b next -t origin/next
git clone git://git.ipfire.org/ipfire-3.x.git
With IPFire-3.x we introduce a new workflow for development. From now on, each developer has got his own sandbox that is published on git.ipfire.org. In this sandbox one can do whatever one imagines. When a new feature is developed it will get finished in this sandbox or branch while it can be shared by many developers through the magic of git. After that, it is merged to the master repository.
If you have got an own developer account you should connect the master repository together with you own:
git clone ssh://firstname.lastname@example.org/pub/git/ipfire-3.x.git # Could also be checked out via the git protocol cd ipfire-3.x/ git remote add user ssh://email@example.com/pub/git/people/user/ipfire-3.x.git
The most common repositories are also mirrored on GitHub at https://github.com/ipfire
Please note that we do not do GitHub pull requests.
