Question

使用虚荣时，我经常会收到超时错误（Timeout::Error: execution expired），并且不断崩溃我的网站。这是发生的事情：

app/controllers/downloads_controller.rb:80:in `go'

在我的控制器中，我有：

  # GET /downloads/1/go
  def go
    @download = Download.find(params[:id])

    # Redirect & track the outbound click
    cookies[:subid] = { :value => "#{@download.to_param}", :expires => 30.days.from_now, :domain => ".example.com", :path => "/" }
    cookies[:download_type] = { :value => "#{@download.download_type}", :expires => 30.days.from_now, :domain => ".example.com", :path => "/" }    
    redirect_to @download.destination.strip, :status => :see_other
    track! :download_start
  end

我在Passenger上使用Ruby 1.9，运行Vanity。有谁知道如何解决这个问题？

谢谢！

更新有人建议将其添加到environment.rb以处理Passenger中的分叉，但仍然无法解决问题......

# monkey patch vanity to force new redis connection when Passenger forks
if defined?(PhusionPassenger) 

  class Vanity::Playground 
    def reconnect_redis 
      @redis = nil
      # Need to remove method or unable to force a reconnect because it
      # hits the method, not the variable.
      class << self ; self ; end.send(:remove_method, :redis)
      redis # Make a new connectiont to redis
    end 
  end

  PhusionPassenger.on_event(:starting_worker_process) do |forked| 
    if forked 
      # We’re in smart spawning mode.
      begin
        Vanity.playground.reconnect_redis 
      rescue Exception => e
        RAILS_DEFAULT_LOGGER.error "Error connecting to redis: #{e.to_s}" 
      end
    end 
  end 
end
