Adding missing fedora release branch to build environment

Every time Fedora has a new release (twice a year) we need to build our Open Source packages for this. Over and over again I forget the basic steps.

For example to build rear for Fedora 19 I need a branch for it in Fedora’s git environment. Basically, I had the following:

$ fedpkg switch-branch -l
Locals:
  el4
  el5
  el6
  f12
  f13
  f14
  f15
  f17
* f18
  master
Remotes:
  origin/el4
  origin/el5
  origin/el6
  origin/f10
  origin/f11
  origin/f12
  origin/f13
  origin/f14
  origin/f15
  origin/f16
  origin/f17
  origin/f18
  origin/master

As you can see in the above example Fedora 19 (f19) is missing in the list. Before requesting the missing branch in Bugzilla’s ticket of your initial software request check if it is not already available with the command:

$ git pull
Enter passphrase for key '~/.ssh/id_rsa_fedora':
From ssh://pkgs.fedoraproject.org/rear
 * [new branch]      f19        -> origin/f19
Already up-to-date.

There it is (no need to request this branch via RedHat Bugzilla). Finally we can switch to the f19 release branch:

$ fedpkg switch-branch f19
Branch f19 set up to track remote branch f19 from origin.
