example of situation where our code blows up with mysql2 'connection is still waiting for a result' errors

authorization.rb

  class Authorization < Goliath::Synchrony::MongoReceiver
    include Goliath::Validation
    include Goliath::Rack::Validator
    
    # time period to aggregate stats over, in seconds

    class MissingApikeyError     < BadRequestError   ; end
    class DatabaseSaveError     < BadRequestError   ; end
    class RateLimitExceededError < ForbiddenError    ; end
    class UserIDMismatchError     < UnauthorizedError ; end

    # this is all pseud-code

    def pre_process
      mongodb_auth_lookup do |resp|
        if resp
          env['user_id'] = resp.user_id
        end
      end
    end

    def post_process
      if body_has_a_object?
        
        body[:object].save if env['user_id'] == body[:user_id]
        
      end
      #in reality we send a 401 if auth isn't valid or user_id mismatch

      [status, headers, body]
    end
end

users.rb

class Users < Foodtree::API
  
  class MissingUserIDError < BadRequestError ; end
    
  def response(env)
    resp = route_request  #this will send PUT to update
    resp
  end

  def update
    if user = User.find(params[:id])
      [200, {}, {:object => user, :user_id => user.id}]
    else
      raise MissingUserIDError
    end
  end
end
