Contributing Code to openATTIC

This is an introduction on how to contribute code or patches to the openATTIC project. If you intend to submit your code upstream, please also review and consider the guidelines outlined in chapter openATTIC Contributing Guidelines.

Keeping Your Local Repository in Sync

If you have followed the instructions in Create Your own openATTIC git Fork on BitBucket, you should already have a local openATTIC instance that is based on the current master branch.

You should update your repository configuration so that you will always pull from the upstream openATTIC repository and push to your openATTIC fork by default. This ensures that your fork is always up to date, by tracking the upstream development.

It is pretty common to name the upstream remote repository upstream and your personal fork origin.

If you’ve cloned your local repo from your personal fork already, it should already be named origin - you can verify this with the following command:

$ git remote -v
origin<username>/openattic.git (fetch)
origin<username>/openattic.git (push)

If the name differs, you can use git remote rename <old> <new>.

Now add the upstream repository by running the following command:

$ git remote add upstream ssh://

Now you can keep your local repository in sync with the upstream repository by running git fetch upstream.

Using git+ssh behind a Proxy Server

If you want to use SSH behind a proxy you may use corkscrew. After the installation, append the following two lines to your $HOME/.ssh/config file:

    ProxyCommand corkscrew <proxy name or ip> <port number> %h %p

Now you can use SSH behind the proxy, because corkscrew now tunnels your SSH connections through the proxy to

Working With Branches

It is strongly recommended to separate changes required for a new feature or for fixing a bug in a separate git branch. Please refer to the git documentation for a detailed introduction into working with branches.

If you intend to submit a patch to the upstream openATTIC repository via a pull request, please make sure to follow the openATTIC Contributing Guidelines.

To create a new feature branch, update your repository, change to the master branch and create your new branch on top of it, in which you commit your feature changes:

$ git fetch upstream
$ git checkout master
$ git pull upstream master
$ git checkout -b <branchname>
< Your code changes >
$ git commit -a

To list your branches type the following (the current branch will be marked with an asterisk):

$ git branch --list

To just see the current branch you are working with type:

$ git rev-parse --abbrev-ref HEAD

After you are done with your changes, you can push them to your fork:

$ git push origin

Submitting Pull Requests

Now that your fork on BitBucket contains your changes in a separate branch, you can create a pull-request on Bitbucket to request an inclusion of the changes you have made into the master branch of the upstream openATTIC repository.

To do this, go to your fork on Bitbucket and click Create pull request in the left panel. On the next page, choose the branch with your changes as source and the openATTIC master branch as target.

Below the Create pull request button, first check out the Diff part if there are any merge conflicts. If you have some, you have go back into your branch and update it:

$ git fetch upstream
$ git rebase upstream/master
<resolve conflicts, mark them as resolved using "git add">
<test and review changes>
$ git rebase --continue
$ git push -f origin

After you have resolved the merge conflicts and pushed them into your fork, retry submitting the pull-request. If you already created a pull request, BitBucket will update it automatically.

After the pull-request was reviewed and accepted, your feature branch will be merged into the main repository. You may delete your feature branch on your local repository and BitBucket fork once it has been merged.
