CHANGELOG.md

• Allow a job to retry indefinitely

  The attempts parameter of the retry_on method now accepts the symbol reference :unlimited in addition to a specific number of retry attempts to allow a developer to specify that a job should retry forever until it succeeds.

  class MyJob < ActiveJob::Base
    retry_on(AlwaysRetryException, attempts: :unlimited)
  
    # the actual job code
  end

• Added possibility to check on :priority in test helper methods assert_enqueued_with and assert_performed_with.

  Wojciech Wnętrzak

• OpenSSL constants are now used for Digest computations.

  Dirkjan Bussink

• Add a Serializer for the Range class.

  This should allow things like MyJob.perform_later(range: 1..100).

• Communicate enqueue failures to callers of perform_later.

  perform_later can now optionally take a block which will execute after the adapter attempts to enqueue the job. The block will receive the job instance as an argument even if the enqueue was not successful. Additionally, ActiveJob adapters now have the ability to raise an ActiveJob::EnqueueError which will be caught and stored in the job instance so code attempting to enqueue jobs can inspect any raised EnqueueError using the block.

  MyJob.perform_later do |job|
    unless job.successfully_enqueued?
      if job.enqueue_error&.message == "Redis was unavailable"
        # invoke some code that will retry the job after a delay
      end
    end
  end
