Amarok is now developed in a Git repository instead of SVN. This was done to help get into place all the needed infrastructure to convert all of KDE, including documentation.

git config --global user.name "Your Legal First and Last Name Here"
git config --global user.email [email protected]

Run these commands before you even ponder ever in your life pushing to a Git repo.

Getting started with git

Depending on whether you simply want to test and follow Amarok development, write the occasional patch, or are an Amarok developer, the steps to use the repo are different.

Follow and test the latest development code

git clone git://gitorious.org/amarok/amarok.git

This creates an 'amarok' directory. cd into that and use it like normal. And when you want to update:

git pull

will download the new changes.

Patch Contributors

You can use the method above, make your changes, then do 'git diff' to create a patch like normal. Or you could use the following rules to create your own fork of Amarok with the additions you would like to request to merge. This makes it easier for Amarok Developers to track your changes and is better for more complicated patches.

Make sure you have created your account on Gitorious and are logged in. Go to the project you want to clone (e.g. Amarok - http://gitorious.org/amarok) and select the branch which you want to clone (in this case Amarok - Mainline which is the master branch).
After selecting the branch you can click "Clone this repository on Gitorious". Give your branch a name and you'll be taken to the page of your newly created clone. On this page you find two git urls: one to publicly clone the repository and the "Push url: [email protected]:~yourname/amarok/yourname-clone.git.
Clone the push url to start working on your clone:

git clone [email protected]:~yourname/amarok/yourname-clone.git

Create a branch for each new feature of bug fix you want to work on:

git branch my_feature_branch

Switch to the new branch:

git checkout my_feature_branch

Work, fix that bug or add the feature...

...work on this checkout - follow the normal development workflow...

Commit it to your local checkout:

git commit -a

Publish it on gitorious:

git push origin my_feature_branch

To submit your patches: Create a merge request on gitorious by going to your clone page and selecting "Request merge" in the menu on the right. Alternatively you could email [email protected] with your branch public branch URL and ask that it be merged. (We just started this, so exactly how to do such things still hasn't been decided).

You can follow the main development branch easily by adding it as remote branch:

git remote add upstream [email protected]:amarok/amarok.git

Update by pulling from the remote:

git pull --rebase upstream master

Remember to use one branch per feature/bug fix!

Amarok Developers

gitorious.org account setup

Create an account on gitorious.org the git hosting service used by Qt and now Amarok.
On your user page, (that's at http://gitorious.org/~your_nick) click on "Manage SSH keys" and add your SSH key.

People with KDE-SVN accounts als should do the following:

Again from the user page, click on "Manage aliases" and add any email addresses you've ever used in KDE SVN. This way any commits you've made in the past are tracked back to you. If your gitorious email address is the only one you ever used, then this step isn't needed.
Request one of the kde-developers admins to add your username to the group (the same rules apply as KDE SVN account requests). This will give you push rights to Amarok. Lydia, Ian and Jeff are all admins.

Setup Amarok Clone

Gitorious has one address for cloning, and another for pushing. The pushing address can be used for cloning, so the easy thing to do is just use that.

git clone [email protected]:amarok/amarok.git

This will create a directory 'amarok'. cd into that and start developing!

Basic Development

90% of the time this is all that is needed:

git pull --rebase
#hack, compile, build. It works!
git status #to check if you want to commit all the modified files
git commit -a
git log
git push

git pull --rebase downloads the latest changes. The --rebase option takes any unpushed local commits and applies them to the latest code, moving it to the top of the history. It is the equivalent of git pull; git rebase origin/master. See the "1. Rebase" section of Shipping Quality Code for a good explanation of what rebase does.

If you have uncommited changes you can not rebase. Instead you can git stash, do the rebase, and then git stash apply.

git status will tell you what files are modified. If you created a new file, use git add on it to "track" it. If there are some junk files, you can add a regexp to .gitignore in the root.

git commit -a will commit all unmodified files. You can use git add and then simply git commit instead if you wish to commit only certain files.

Use git log to review the local unpushed commits. Possibly also useful is git diff origin/master, which will give you a diff between the current checkout and what is in the central repo.

git push pushes all the local commits to the central repo.
