Issue tracking and coordination
We use OpenProject for development coordination and roadmap planning. Please have a look at the following lists:
The main development branch for upcoming releases is
If in doubt, create your pull request against
All new features, gem updates and bugfixes for the upcoming release should go into the
For contributing source code, please follow the git workflow below:
- Fork OpenProject on GitHub
- Clone your fork to your development machine:
git clone firstname.lastname@example.org/<username>/openproject
- Optional: Add the original OpenProject repository as a remote, so you can fetch changes:
git remote add upstream email@example.com:opf/openproject
- Make sure you're on the right branch. The main development branch is
git checkout dev
- Create a feature branch:
git checkout -b feature/<short description of your feature>
- Make your changes, then push the branch into your own repository:
git push origin <your feature branch>
- Create a pull request against a branch of of the <opf/openproject> repository, containing a clear description of what the pull request attempts to change and/or fix.
If your pull request does not contain a description for what it does and what it's intentions are, we will reject it. If you are working on a specific work package from the list, you may include a link to that work package in the description, so we can track your work.
The core contributor team will then review your pull request according to our code review guideline. Please note that you can add commits after the pull request has been created by pushing to the branch in your fork.
If you want to contribute to the localization of OpenProject and its plugins you can do so on Crowdin. Once a day we fetch those locales and upload them to GitHub.
More on this topic can be found in our blog post.
Please add tests to your code to verify functionality, especially if it is a new feature.
Pull requests will be verified by TravisCI as well, but please run them locally as well and make sure they are green before creating your pull request. We have a lot of pull requests coming in and it takes some time to run the complete suite for each one.
If you push to your branch in quick sucession, please consider stopping the associated Travis builds, as Travis will run for each commit. This is especially true if you force push to the branch.
Please also use
[ci skip] in your commit message to suppress builds which are not necessary
(e.g. after fixing a typo in the
Bugs and hotfixes
Bugfixes for one of the actively supported versions of OpenProject should be issued against the respective branch.
A fix for the current version (called "Hotfix" and the branch ideally being named
release/* and a fix for the former version
(called "Backport" and the branch ideally being named
backport/*. We will try to merge hotfixes into dev branch
but if that is no trivial task, we might ask you to create another PR for that.
Inactive pull requests
We want to keep the Pull request list as cleaned up as possible - we will aim close pull requests
after an inactivity period of 30 days (no comments, no further pushes)
which are not labelled as
work in progress by us.
