Capistrano: "cap deploy" doesn't take effect when deploying a Rails application

I am deploying my rails application using Capistrano. Once I have made changes to my app I do "cap deploy" and it seems working properly, but changes don't take effect. I always have to do "cap deploy:stop" and "cap deploy:start" and then everything is fine. So I guess it has to do with "cap deploy:restart" which is run when deploying changes.

here is my deploy.rb: deploy.rb gist

Hope that someone can help.

Thank you in advance

Just noticed in line (105) in your gist

task :restart, :except => { :no_release => true } do
  if File.exist?("/tmp/unicorn.example.pid")
    run "kill -s USR2 `cat /tmp/unicorn.example.pid`"
  end
end

that you are testing for the pid file existence on your local machine. Instead you should do that on your server. Try changing it to

task :restart, :except => { :no_release => true } do
  run "test -f /tmp/unicorn.example.pid && kill -s USR2 `cat /tmp/unicorn.example.pid`"
end

But remember that it still fails silently if the pid file is missing.

If you restart unicorn using the USR2 signal it doesn't automatically know the correct environment for bundler. Check out this gist (specially the before_exec block) and adjust your unicorn config accordingly.

Hope that helps.
