Update tickets only for specific branches

I managed to use the following work-around in the post-receive hook:

if ref.ends_with?('master')
  Configuration.load(CONFIG_DIR)
  TicketUpdate.new(rev_old, rev_new, ref).parse.send_changes
end

My git version is 1.6.1 (local and remote)

I have local mater, production and staging branches and the same on remote.

I make changes to master, push to my remote master for my colleagues. Once a bunch of changes are done, I merge local master into my local staging which then I push to my remote staging. Once QA approves of staging, I merge my local staging into my local production and push it to my remote production.

I got around the problem of multiple updates to my LH tickets by only passing the commits on the remote master to the hook.
