A simple goliath API that is supposed to take the hash of an uploaded stream.

sha_stream.rb

#!/usr/bin/env ruby
# encoding: utf-8

require 'goliath'
require 'digest/sha1'

class ShaStream < Goliath::API
  # use Goliath::Rack::Params

  def on_headers(env, headers)
    env['async-digest'] = Digest::SHA1.new # SHA1 or MD5
  end

  def on_body(env, data)
    env['async-digest'] << data
  end

  def response(env)
    [200, {}, ["sha1: #{env['async-digest'].hexdigest}\n"]]
  end
end

# run with ruby sha_stream.rb -sv -p 9000
# call with curl -F "file=@goliath/github.rb" "localhost:9000/stream"
# expected behavior: sha1 should always be the same
