ruby - Sinatra Restarting Webrick Server after ctrl-c -
require 'sinatra' require 'rubygems' class testserver < sinatra::application set :port, 22340 '/' "hello world" end run! if app_file == $0 end very simple application ruby 2.0.0-p0 , sinatra 1.4.2
when ctrl-c webrick server restarts on default port... see output below

the problem you’re not correctly using sinatra modular style. rather requiring sinatra , inheriting sinatra::application should require sinatra/base , inherit sinatra::base.
what’s happening this. require plain sinatra, in turn requires sinatra/main. file adds at_exit handler runs built in server (unless disable it). explicitly call run! in own code, server starts because of call, when exit at_exit handler starts server again. requiring sinatra/base doesn’t start built-in server @ exit, you’ll have own explicit call run!.
require 'sinatra/base' # change here require 'rubygems' class testserver < sinatra::base # , here set :port, 22340 '/' "hello world" end run! if app_file == $0 end
