rails--rails/activejob/CHANGELOG.md

Rails 5.1.0.beta1 (February 23, 2017)

• Correctly set test adapter when configure the queue adapter on a per job.

  Fixes #26360.

  Yuji Yaginuma

• Removed deprecated support to passing the adapter class to .queue_adapter.

  Rafael Mendonça França

• Removed deprecated #original_exception in ActiveJob::DeserializationError.

  Rafael Mendonça França

• Added instance variable @queue to JobWrapper.

  This will fix issues in resque-scheduler #job_to_hash method, so we can use #enqueue_delayed_selection, #remove_delayed method in resque-scheduler smoothly.

  mu29

• Yield the job instance so you have access to things like job.arguments on the custom logic after retries fail.

  DHH

• Added declarative exception handling via ActiveJob::Base.retry_on and ActiveJob::Base.discard_on.

  Examples:

  class RemoteServiceJob < ActiveJob::Base
    retry_on CustomAppException # defaults to 3s wait, 5 attempts
    retry_on AnotherCustomAppException, wait: ->(executions) { executions * 2 }
    retry_on ActiveRecord::Deadlocked, wait: 5.seconds, attempts: 3
    retry_on Net::OpenTimeout, wait: :exponentially_longer, attempts: 10
    discard_on ActiveJob::DeserializationError
  
    def perform(*args)
      # Might raise CustomAppException or AnotherCustomAppException for something domain specific
      # Might raise ActiveRecord::Deadlocked when a local db deadlock is detected
      # Might raise Net::OpenTimeout when the remote service is down
    end
  end
