rails--rails/activejob/CHANGELOG.md

• Don't run after_enqueue and after_perform callbacks if the callback chain is halted.

  class MyJob < ApplicationJob
    before_enqueue { throw(:abort) }
    after_enqueue { # won't enter here anymore }
  end
  

  after_enqueue and after_perform callbacks will no longer run if the callback chain is halted. This behaviour is a breaking change and won't take effect until Rails 6.2. To enable this behaviour in your app right now, you can add in your app's configuration file config.active_job.skip_after_callbacks_if_terminated = true

• Fix enqueuing and performing incorrect logging message.

  Jobs will no longer always log "Enqueued MyJob" or "Performed MyJob" when they actually didn't get enqueued/performed.

    class MyJob < ApplicationJob
      before_enqueue { throw(:abort) }
    end
  
    MyJob.perform_later # Will no longer log "Enqueued MyJob" since job wasn't even enqueued through adapter.
  

  A new message will be logged in case a job couldn't be enqueued, either because the callback chain was halted or because an exception happened during enqueing. (i.e. Redis is down when you try to enqueue your job)

  Edouard Chin

• Add an option to disable logging of the job arguments when enqueuing and executing the job.

  class SensitiveJob < ApplicationJob
    self.log_arguments = false
  
    def perform(my_sensitive_argument)
    end
  end
  

  When dealing with sensitive arguments as password and tokens it is now possible to configure the job to not put the sensitive argument in the logs.

  Rafael Mendonça França

• Changes in queue_name_prefix of a job no longer affects all other jobs.

  Fixes #37084.

  Lucas Mansur

• Allow Class and Module instances to be serialized.

  Kevin Deisz

• Log potential matches in assert_enqueued_with and assert_performed_with.

  Gareth du Plooy

• Add at argument to the perform_enqueued_jobs test helper.

  John Crepezzi, Eileen Uchitelle

• assert_enqueued_with and assert_performed_with can now test jobs with relative delay.

  Vlado Cingel

• Add jitter to :exponentially_longer

  ActiveJob::Exceptions.retry_on with :exponentially_longer now uses a random amount of jitter in order to prevent the thundering herd effect.. Defaults to 15% (represented as 0.15) but overridable via the :jitter option when using retry_on. Jitter is applied when an Integer, ActiveSupport::Duration or exponentially_longer, is passed to the wait argument in retry_on.

  retry_on(MyError, wait: :exponentially_longer, jitter: 0.30)
