Rebasing Topc Branches

For the purpose of this example we will assume the following:

• You are rebasing the ec2 branch onto the master branch.
• The master branch contains the tag "Ubuntu-2.6.32-29.58" at the point where you want the rebase.
• Clone a new copy of the Lucid kernel tree

   git clone zinc.canonical.com:/srv/kernel.ubuntu.com/git/ubuntu/ubuntu-karmic.git

• For purposes of this example we will be rebasing the ec2 topic branch

   cd ubuntu-karmic
   git branch --track ec2 origin/ec2

• Before rebasing the ec2 branch it must be prepared. If a "start new release" has not been performed upon it, that must be done.

   git co ec2
   maint-startnewrelease
   git co master

• Do the rebase.

   maint-rebase-branch ec2 Ubuntu-2.6.32-29.58

• Once the rebase completes successfully, inspect the rebase. You should be currently in a temporary topic branch named "auto-tmp-rebase".
• Once you are satisfied that the rebase worked the way you wanted, fixup the actual ec2 topic branch.

   git co ec2
   git reset --hard auto-tmp-rebase

• You can now go on to finish up this branch for release and testing.

  A repository of useful tools. This is where maint-rebase-branch comes from.

To Do:

1. Create another wiki page that show how to do this without using the script for the times the script fails.
