Development procedure


Any change to c2cgeoportal and CGXP requires a GitHub pull request.

To give everyone a chance to review changes pull requests should not stay open for at least 24 hours.

Any main developers of c2cgeoportal projects can take responsibility for merging commits in the main (master) branch.

Pull requests with significant impacts can and should be reviewed by more than one person.

Working with Git and GitHub

Create a topic branch

To create a Git branch from the master branch use:

$ git checkout -b <branch_name> master

You can then add commits to your branch, and push commits to a remote branch using:

$ git push -u origin <branch_name>

The -u option adds an upstream (tracking) reference for the branch. This is optional, but convenient. Once the branch has an upstream reference you can push commits by just using git push.

The “origin” remote can either represent the main repository (that in the “camptocamp” organization) or your own fork. Creating branches in the main repository can ease collaboration between developers, but isn’t required.

Sync up a topic branch from master

To update a branch from the master you first need to update your local master branch:

$ git checkout master
$ git fetch origin
$ git merge origin/master


You’ll use “upstream” instead of “origin” if “origin” references your own fork.

You can now update your branch from master:

$ git checkout <branch_name>
$ git rebase master
$ git push origin <branch_name>

Pull requests

Making a pull request is done via the GitHub web interface. Open your branch in the browser (e.g. and press the Pull Request button.

Once a pull request is merged it is good practise to add a comment in the pull request, for others to get notifications.

Remove branches

Once you’re done with a topic branch (because its commits are merged in the master branch) you can remove it with:

$ git branch -D <branch_name>

To remove a remote branch use:

$ git push origin :<branch_name>

This means push nothing to “branch_name” on the origin remote.
