We make heavy use of puppet environments in our workflow. Using r10k, git branches are magically mapped to environments. This allows a process where anyone one the team can individually work on a new feature or change, and then we can collaborate and review/revise/test in a controlled manner. We can rebase to the production branch, and use the diff output as part of our change-management documentation. Once the change is merged, however, sometimes the original branch is not deleted.
In doing a puppet-server migration, I decided to clean up some of these “forgotten” branches. Not all branches end up being merged, though; sometimes we will prove out a change, decide not to implement it in production, but want to keep it for future reference. Or, maybe the change is still a work in progress.
To list the remote branches that have already been merged (into the
$ git branch -r --merged production remotes/origin/HEAD -> origin/production remotes/origin/new_feature_foo remotes/origin/another_change_bar
These can be deleted. I can never remember the syntax for deleting a
remote branch, so I use a
nuke alias that deletes both the local and
$ git config --get alias.nuke !sh -c 'git branch -D $1 && git push origin :$1' - $ git nuke new_feature_foo Deleted branch new_feature_foo (was 0b43193). remote: Deploying to puppetmaster. remote: r10k new_feature_foo environment removed, will be purged on next run. remote: Sending notifications. remote: Mirroring to GitHub. remote: To firstname.lastname@example.org:/bowdoincollege/noc-puppet remote: - [deleted] new_feature_foo To git.bowdoin.edu:/noc/puppet.git - [deleted] new_feature_foo
Alternatively, you may want to see all branches that have not been
merged (yet) into the
$ git branch -a --no-merged production rejected_feature work_in_progress production remotes/origin/HEAD -> origin/production remotes/origin/rejected_feature remotes/origin/work_in_progress
I took a look at these and cleaned up what I could, but there were a few from other team members that I didn’t know about. I asked everyone to take a look and clean up any unneeded branches/environments. After they had deleted the remote branches, I was able to clean up my local repository:
$ git remote prune origin Pruning origin URL: email@example.com:/noc/puppet.git * [pruned] origin/arubaguestportal * [pruned] origin/freeradius_arubalab * [pruned] origin/freeradius_nopersontype * [pruned] origin/opsview_mitsubishiups * [pruned] origin/wlcforrancid
This deletes (prunes) any local tracking branches that no longer exist on the remote.
