ruby - Handling exceptions in forked process -

i'm building sinatra api call trigger long-running operation in subprocess. i'm using exception_handler gem, don't understand how i'd use in forked process.

sinatra app:

require 'sinatra' require 'rubygems' require 'bundler/setup' require 'exception_notification'  use exceptionnotification::rack,   :email => {     :email_prefix => "[example] ",     :sender_address => %{"notifier" <notifier@example.com>},     :exception_recipients => %w{me@example.com},     :delivery_method => :sendmail   }  '/error'   raise 'bad!' # notification gets sent end  '/error_async'   p1 = fork     sleep 10     raise 'bad! (async)' # notification never gets sent   end   process.detach(p1) end 

got working, per docs:

get '/error_async'    p1 = fork      begin       sleep 10       raise 'bad! (async)'     rescue exception => e       exceptionnotifier.notify_exception(e)     end    end   process.detach(p1)  end
