Information and commands on this page may no longer be valid and should be used with care. Please see the KDE Git hub page for more details. 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.

Found here. 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://anongit.kde.org/amarok 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 Contributions This is still a work in progress, as we work on getting ReviewBoard set up. In the meantime, hold on to any patches, or email them to [email protected] -- just be sure to follow the thread to ensure that it doesn't get lost :-) If you want to use a local clone for working on bug fixes or features, do the following: Create a branch for each new feature or 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 You can follow the main development branch easily by adding it as remote branch: git remote add upstream git://git.kde.org/amarok Update by pulling from the remote: git pull --rebase upstream master Remember to use one branch per feature/bug fix! Amarok Developers Account Setup If you don't already have a SSH account to the KDE SVN, please file a sysadmin bug on http://sysadmin.kde.org/tickets/ and provide your logon and your SSH pub key. Setup Amarok Clone Once you have a KDE development SSH account, a basic local clone for development work that allows push access can be created by running: git clone [email protected]:amarok This will place a clone in the "amarok" subdirectory of the current folder. If for some reason port 22 will not work for you (such as if you behind a firewall allowing only ports 80 and 443 through) you can use port 443 on git.kde.org by specifying the port in ~/.ssh/config: Host git.kde.org Port 443 You can also create your own server-side clone of the Amarok repository and store your changes there. Others can then pull from your repository or add your repository as a remote. Please note that personal clones are using KDE infrastructure and meant for KDE-relevant work, and as such you cannot change the access policy that allows everyone to read these clones (but you can change who can write to them, as explained below). Please do not create clones to e.g. make changes to customize code for your company. If you want to do this, host your clone on Gitorious.org or GitHub.com instead. To create a personal clone, run the following command, substituting your KDE username and a reponame of your choice, *without* a trailing ".git": ssh [email protected] clone amarok clones/amarok.git/[username]/[reponame] After that, you will have a fully functioning repository of your own at git://git.kde.org/clones/amarok.git/[username]/[reponame] or [email protected]:clones/amarok.git/[username]/[reponame] for read-only and push URLs, respectively. You can delete this repository at any time by running the "destroy" command: ssh [email protected] destroy clones/amarok.git/[username]/[reponame] Rights Management When your clone is created, it is setup to allow all KDE developers push access to it. This is in keeping with KDE's everyone-can-write-anywhere philosophy. You are strongly encouraged to keep this default. However, we understand that at times you may want to ensure that the work you are doing is not modified by anyone else until you are finished, or reach a milestone, or some such thing. As such, you can adjust who can write to your cloned repository. To see the current permissions, use the "getperms" command: ssh [email protected] getperms clones/amarok.git/mitchell/testrepo RW = @all @all is a special groupname that indicates all KDE developers. It is the only special name allowed in the permissions. To modify them, create a file named anything you like -- I'll use "myperms". In "myperms" enter those that should have RW access by their KDE user account name. The RW statements are cumulative, or can specify multiple user accounts on one line: RW = hein bcooskley RW = toma At the end of this, the total push permissions will be comprised of *you* (the creator of the clone, in my case "mitchell"), hein, bcooskley *and* toma. Note that *you* are the only one that can push and delete new branches and tags; the other contributors only have push access. In other words, you are your own release manager for your clone. Now, use the "setperms" command to set the permissions, passing in the file you created: ssh [email protected] setperms clones/amarok.git/mitchell/testrepo < myperms New perms are: RW = hein bcooksley RW = toma 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. Follow remote feature branch With git, feature branches are cheap and easy. Here's how to follow a feature branch someone else has already setup. Remember that you can't push to git:// URL's when picking what URL to use. git remote add jeff git://git.kde.org/clones/amarok.git/mitchell/pudaction.git git remote update git branch -a git branch jeff-pud jeff/pudaction-removal git checkout jeff-pud #and later you want to switch back to the mainline git checkout master git remote add adds a new remote named 'jeff' with the given URL. Think of remotes like bookmarks: you could always just explicitly pull from a URL instead. git remote update downloads all the remotes you have without merging them, including the remote you just defined. This is a handy command if you're tracking multiple remotes. git branch -a this lists all the branches you have, including the remote branches. Find the new branch you want to look at. git branch this command creates a local branch called 'jeff-pud' that tracks the remote branch 'pud-action/pudaction-removal'. You figured out the name of the latter in the previous command. git checkout is how you switch between branches.
