===GIT/KDE useful recipes===
 
 
 
===Backporting fixes===
 
Let's say you just fixed a bug in kde-apps and you commited it to the master and git reported it as commit id 0f601b3d28. You want now to get it backported to the latest released version.
 
 
 
When you issue:
 
<syntaxhighlight lang="bash">git branch -a</syntaxhighlight>
 
you get
 
<syntaxhighlight lang="bash">
 
* master
 
  remotes/origin/4.6
 
  remotes/origin/HEAD -> origin/master
 
  remotes/origin/KDE/4.0
 
  remotes/origin/KDE/4.1
 
  remotes/origin/KDE/4.2
 
  remotes/origin/KDE/4.3
 
  remotes/origin/KDE/4.4
 
  remotes/origin/KDE/4.5
 
  remotes/origin/KDE/4.6
 
  remotes/origin/kdepim/enterprise-4.0.83
 
  remotes/origin/kdepim/enterprise-4.1
 
  remotes/origin/master
 
</syntaxhighlight>
 
The red-colored lines are showing you the branches that are living into the main repository (you must have enabled git colors before this).
 
 
 
You need to backport to the last released version, which lives in the remotes/origin/KDE/4.6:
 
 
 
<syntaxhighlight lang="bash">
 
git checkout -b KDE/4.6 origin/KDE/4.6
 
</syntaxhighlight>
 
This will get get you on the backport branch. Verify the diff between this old branch and the origin branch where you commited your fix :
 
<syntaxhighlight lang="bash">
 
git diff origin <fileYouModified>
 
</syntaxhighlight>
 
 
 
To apply your fix, do this:
 
<syntaxhighlight lang="bash">
 
git cherry-pick 0f601b3d28
 
</syntaxhighlight>
 
You just applied your fix (well, if you get merging errors, just fix them as usual). See it by yourself:
 
<syntaxhighlight lang="bash">git log</syntaxhighlight>
 
 
 
Now push your changes:
 
<syntaxhighlight lang="bash">
 
git push
 
</syntaxhighlight>
 
Don't forget to get back on the main branch:
 
<syntaxhighlight lang="bash">git checkout master</syntaxhighlight>
