如何使用ActiveJob杀死Rails 4中的sidekiq作业

Question

Let's say we have test job:

class TestJob < ActiveJob::Base
  queue_as :default

  def perform(video)
    video.process
  end
end

After it we run bundle exec sidekiq start

And run in new terminal window in rails console

Video.first.pending!; TestJob.perform_later(Video.first)

Job is running, ffmpeg is on background, everything is fine, but according to official sidekiq wiki docs I try:

require 'sidekiq/api'
Sidekiq::Queue.new
=> #<Sidekiq::Queue:0x00000006406978 @name="default", @rname="queue:default">

Sidekiq::Queue.new.each {|job| puts job}
=> nil
Sidekiq::Queue.new.size
=> 0
ss = Sidekiq::ScheduledSet.new
=> #<Sidekiq::ScheduledSet:0x000000064a4330 @_size=0, @name="schedule">
ss.size
=> 0

Why there is no jobs? The job is running successfully ( I see it also in first window where sidekiq starts, but I can't see and delete it in rails console )

I am using Ubuntu 14 if it helps

With best regards, Ruslan.

UPD: It looks that ps = Sidekiq::ProcessSet.new; ps.each(&:quiet!) ps = Sidekiq::ProcessSet.new; ps.each(&:quiet!) works , but it doesn't stop my ffmpeg process this part of code internally in process:

cmd = "ffmpeg -i #{input_file.shellescape} #{options} -threads 0 -y #{self.path + outfile}"
pid = spawn(cmd, :out => output_file, :err => output_file)
Process.wait(pid)

How to stop it?

Answer 1

如果作业正在处理，则不再排队。

Answer 2

I use sidekiq web UI and various queues for my jobs. If I realize that particular job is failing I can clear out the queue of subsequent jobs of the same class.
