I have got Sinatra/Rails app and an action which starts some long process.
Ordinary I make a queue for background jobs. But this case is too simple and background process starts very rarely, so queue is an overhead.
So how could I run background process without queue?
get "/build_logs/:project" do
LogBuilder.new(params[:project]).generate
"done"
end
I've tried to make it as a new Thread or Process fork, but it didn't help.

I have had success with this (simplified) in Sinatra:
get '/start_process'
@@pid = Process.spawn('external_command_to_run')
end
This returns the Process ID, which you can use to terminate the process later if you need. Also, this is on Linux, it will not work on Windows.
