The Git repository for sip-router is available through HTTP, SSH, the proprietary Git protocol and CVS. The HTTP and Git access methods provide only read-only access to the repository, that means you will be able to check out your own copy of the repository, but you will not be able to push your changes back.

To clone the repository using Git protocol do (recommended for read-only access):

git clone git://git.sip-router.org/sip-router

To clone the repository using HTTP do:

git clone http://git.sip-router.org/sip-router

If you have write access to the repository and access to the git host then you can checkout the repository using ssh:

git clone ssh://username@git.sip-router.org/sip-router

where username is your username on host git.sip-router.org. Please see also GIT Quick Start Guide if you plan to commit changes.

After "cloning" the repository the default branch that is checked out is master. Right now there are 3 important branches in the repository:

1. master - latest code, all the new development goes here.
2. sr_3.0 - branch for the future sip-router 3.0 release, in process of being stabilized.
3. kamailio_3.0 - branch for the kamailio 3.0 release (kamailio 3.0 is the first kamailio release that will be based on sip-router, in this case the sr_3.0 branch).

If you are interested in a different branch then master, you have to use git checkout to change the branch, e.g.:

cd sip-router
git checkout --track -b sr_3.0 origin/sr_3.0

(replace sr_3.0 with the desired branch). The above command will create a local sr_3.0 branch that will track changes in the remote (repository) version of the same branch (origin/sr_3.0). Note that as an alternative, if you have a new git version you could replace the above command and the clone command with:

git clone --branch sr_3.0 git://git.sip-router.org/sip-router
cd sip-router

You need to do all of the above only once. After you already have a "clone" you can update your local copy with the latest changes in the repository using git pull. E.g.:

git fetch origin
git pull --rebase origin sr_3.0

(replace sr_3.0 with the branch you are on).

You can also browse the repository through the gitweb WWW interface at http://git.sip-router.org and you can download daily snapshots from http://sip-router.org/tarballs/sr. If you prefer you could use cvs instead of git (see below), but it will be significantly slower.

The repository is setup so that you can commit only to the following branches:

• <your_username>/*
• tmp/*
• master

In general you should not commit to master. You should use your own branch for work-in-progress and only when you think it's in a good enough form (it compiles and looks stable), you should merge it to master.

Please create the commit messages following the git convention:

• start with one short line, preferably less then 50 chars summarizing the changes
• follow by exactly one empty line
• then a more detailed description (if necessary), but make sure you don't have lines longer then 72 characters

Make sure you read git-commit-guidelines.

Example vim/gvim config additions for git commit messages:

" git commits edit
au BufNewFile,BufRead COMMIT_EDITMSG setf git
au BufNewFile,BufRead COMMIT_EDITMSG set ai tw=66

Please see GIT Commit into master HOWTO.

Please see GIT Merge into master HOWTO.

The repository is also available through cvs for those who do not want or cannot use git. A recent version of cvs client is needed to access the repository. You need to have the following two environment variable set if you want to access the repository anonymously through the pserver method:

export CVSROOT=:pserver:anonymous@cvs.sip-router.org/sip-router
export CVS_SERVER=git-cvsserver

To checkout the source tree you need to specify the name of the head (a.k.a branch) instead of the cvs module!. You can see what branches are available in the repository in gitweb at http://git.sip-router.org (look for heads)

The most important head names are:

• master - This is the main development/unstable branch (HEAD in cvs terminology)
• sr_3.0 - This is the (soon to be) stable sip-router 3.0 branch.
• kamailio_3.0 - This is the kamailio 3.0 stable branch (based on sr_3.0).

So if you want to checkout the latest development version then do:

cvs co master

CVS write access is only available through ssh:

export CVSROOT=:ext:username@cvs.sip-router.org/sip-router
export CVS_SERVER=git-cvsserver

cvs co master

The cvs compatibility layer does not support tagging and branching, so you would need to use git for that.
