Shotgun and Process.fork

[andyl]

I have a Sinatra app that does something like this:

    post '/action' do
      pid = Process.fork { sleep 10; do_some_background_stuff; }
      redirect('/another_page')
    end

I like to use Shotgun for development.  But it seems that Shotgun waits for the forked process to end before it redirects.  That makes it unusable for me.

Does anyone know a workaround, so I can use Process.fork in conjunction with Shotgun??

Tx, Andy

Looks like someone else had the same question: https://groups.google.com/forum/#!topic/sinatrarb/xH2Eml0L-lg

Sorry about the duplication - but I guess that means others have the same question...

By the way - I have gotten this to work find using Phusion Passenger and thin (production mode - no code reloading). 

But I'd like to get this working using Shotgun for development.  (Or - if there was another compatible solution for Shotgun-like code reloading, I'd love to hear about that!)

Since shotgun forks for every request on its own and then kills that fork after the request, there is no way to fix this, I guess.

I came up with an example that works.  It relies on the 'daemons' gem.

Here's the gist:

I've tested it with with shotgun/thin, rackup/webrick, rackup/thin, and passenger on Ubuntu 10.10.
