Content-Type

Use text/csv content type - why? why not?? use special case for windows (excel) e.g.

def csv_content_type
  case request.user_agent
  when /windows/i then 'application/vnd.ms-excel'
  else                 'text/csv'
  end
end

Rack.builder

(auto-)wrap app in rack builder - why? why not?

  • let you use use for middleware

  • also support map or add a "custom" mount - why? why not?

builder = Rack::Builder.new do

  map "/rack" do
    run lambda{|env| [200, {"Content-Type" => "text/html"}, ["PATH_INFO: #{env["PATH_INFO"]}"]]}
  end

  map "/mini" do
    run MiniApp.new
  end

  run App.new
end

app = builder.to_app

add before and after filters / hooks

add

before do
end

after do
end

why? why not??

call.dup

sinatra 2.0 uses a mutex with synchonize on Base.call - add it too? why? why not?

is Base#call.dup still recommended (good enough)
