ruby-on-rails - Getting hirefire to work with Rails 3.1.3, DJ 3.0.0, Heroku Cedar Stack

Question

I'm trying to get hirefire to work with Heroku Cedar Stack. I tried using this patch, but that doesn't seem to help either. Workers are not getting spun up at all. Anybody here has a solution that works?

在查看了hirefire source后，我找到了解决方案。我的问题是作业队列中有一个锁定的作业。因此，delayed_job.working 结果是 1 而不是 0。此外，由于锁定的工作，delayed_job.jobs 也是 1。因此没有雇用任何工人。我从队列中清除了所有的工作，然后hirefire 就像一个魅力一样工作。

    def hirefire_hire
      delayed_job = ::Delayed::Job.new
      if delayed_job.working == 0 \
      or delayed_job.jobs    == 1
        environment.hire
      end
    end

我认为应该修改此检查以检查未锁定的作业数量或类似性质的东西。
