THIS IS A DRAFT, DO NOT USE!
This Git Workflow is the recommended KDE Git Workflow for smaller projects where new features are developed in local and/or remote feature branches before being reviewed and merged back into the master branch.
This workflow is designed to be used after initial use of the Simple Workflow. It is assumed you have read and mastered the basic concepts as outlined in that Workflow, such as unstaged and staged changes, committing, rebasing and pushing.
Note that each module may choose to adopt a more complex workflow, in particular the Integration Branch Workflow, and you should check with your modules maintainers if this is the case.
See the Simple Workflow Set-up section for instructions on configuring Git and Cloning your Repository
By default when you first create a repository clone there is only a single local branch called 'master'. It is not good practice to do development in master, it is better kept clean for reference. Instead all work should be performed in a new local branch, even bug fixes.
To see what local branches you have:
This will initially appear as follows, with the * indicating your current working branch:
To see all local and remote branches:
git branch -a
This will initially look something like:
* master remotes/origin/HEAD -> origin/master remotes/origin/KDE/4.5 remotes/origin/KDE/4.6 remotes/origin/kdecore/klocale-win remotes/origin/kdeui/kdatetimeedit
To create a new local branch:
git branch <new-branch>
Now running git branch will show:
* master my-new-branch
To change to the new branch to work on it:
git checkout <new-branch>
Now running git branch will show:
master * my-new-branch
This sequence will create a new branch based on whatever local branch you were already in, i.e. that includes all the history of the original branch, which can be useful in building a hierarchy of dependent changes.
You may prefer to base your new branch on a remote branch such as the master branch of the central repository so you can integrate any new development. This is called 'tracking' a remote branch and is recommended for most work branches:
git branch --track <local-branch> <remote-branch>
For example to develop a new feature called 'bar' based on the central repository master branch:
git branch --track new-bar-feature origin/master
Once you have finished with a local feature branch and pushed all your commits to the central repository you can delete the local branch if you no longer require it.
First, you have to change to a different branch:
git checkout master
Then you can delete the feature branch:
git -d <local-branch>
This example workflow is for working on new features in a feature branch hosted on the central repository.
This workflow is recommended for larger features or where there are many developers on a project.
This example workflow is for locally fixing bugs in both the stable and unstable branches and pushing them to the central repository.
In Git, stable branches are just regular branches that have special meaning to a project and a possibly a special naming scheme to distinguish them. For example, kdelibs includes the following branches on the central repository:
origin/HEAD -> origin/master origin/KDE/4.5 origin/KDE/4.6 origin/kdecore/klocale-win origin/kdeui/kdatetimeedit origin/master
Here origin/KDE/4.6 is the 4.6 release of kdelibs.
Making bug fixes to stable branches is thus fundamentally the same as working on a feature branch, but with the added step of needing to push the bug fix to both the stable and unstable branch in the central repository.
In the Simple Workflow bug fixing section we describe a simple way to perform bug fixes for both stable and unstable branches in the same repository clone.
The basic workflow works fine except switching between unstable and stable branches inside a single Git repository can lead to large rebuilds if the unstable branch has diverged too much from the stable branch. On a small app this overhead may be small enough to not be a problem, but in most cases this constant rebuilding will be a waste of time.
This workflow uses the [script] to create separate work directories and builds for stable and unstable branches. This depends on you setting different up KDE Environments for the separate builds.
