How to do a proper finish hook?

[devvmh]

Related to #424, the code I provided there doesn't do what I'd like. Given these two tasks

namespace :notification do
  notifier = Slack::Notifier.new('https://hook.bearychat.com/=bw6KQ/incoming/2d9481657d9013eb61cb41d3708f39a8')
  task :start_deploy do
    notifier.ping %(mina 1.x test - start deploy task ran)
    command %(echo 'started')
  end

  task :finish_deploy do
    notifier.ping %(mina 1.x test - finish deploy task ran)
    command %(echo 'finished')
  end
end

I get this output:

       started
       Elapsed time: 0.00 seconds
       finished
       Elapsed time: 0.00 seconds
-----> Creating a temporary build path
-----> Deploy finished
-----> Building
-----> Moving build to /home/deploy/mina-deploys/minatest/cure/releases/20160815063411
-----> Build finished
-----> Launching
-----> Updating the /home/deploy/mina-deploys/minatest/cure/current symlink
-----> Done. Deployed version 20160815063411
       Elapsed time: 1.47 seconds

What I would like is for the finish_deploy output (and slack notification) to run after passenger is restarted, like so:

       started
       Elapsed time: 0.00 seconds
-----> Creating a temporary build path
-----> Deploy finished
-----> Building
-----> Moving build to /home/deploy/mina-deploys/minatest/cure/releases/20160815063411
-----> Build finished
-----> Launching
-----> Updating the /home/deploy/mina-deploys/minatest/cure/current symlink
-----> Done. Deployed version 20160815063411
       Elapsed time: 1.47 seconds
       finished
       Elapsed time: 0.00 seconds

Is there a way to make mina do what I want?

Ah, got it, I need to change this

task deploy: :environment do
  deploy do
    run(:local) { invoke :'notification:start_deploy' }
    invoke :'git:clone'
    # ...other commands...
    invoke :'deploy:cleanup'

    on :launch do
      invoke :'passenger:restart'
      run(:local) { invoke :'notification:finish_deploy' }
    end
  end
end

to this

task deploy: :environment do
  run(:local) { invoke :'notification:start_deploy' }

  deploy do
    invoke :'git:clone'
    # ...other commands...
    invoke :'deploy:cleanup'

    on :launch do
      invoke :'passenger:restart'
    end
  end

  run(:local) { invoke :'notification:finish_deploy' }
end
