• Allow jobs to the interrupted and resumed with Continuations

  A job can use Continuations by including the ::ActiveJob::Continuable concern. Continuations split jobs into steps. When the queuing system is shutting down jobs can be interrupted and their progress saved.

  class ProcessImportJob
    include ActiveJob::Continuable
  
    def perform(import_id)
      @import = Import.find(import_id)
  
      # block format
      step :initialize do
        @import.initialize
      end
  
      # step with cursor, the cursor is saved when the job is interrupted
      step :process do |step|
        @import.records.find_each(start: step.cursor) do |record|
          record.process
          step.advance! from: record.id
        end
      end
  
      # method format
      step :finalize
  
      private
        def finalize
          @import.finalize
        end
    end
  end

• Defer invocation of ActiveJob enqueue callbacks until after commit when enqueue_after_transaction_commit is enabled.

• Add report: option to ActiveJob::Base#retry_on and #discard_on

  When the report: option is passed, errors will be reported to the error reporter before being retried / discarded.

• Accept a block for ActiveJob::ConfiguredJob#perform_later.

  This was inconsistent with a regular ActiveJob::Base#perform_later.

• Raise a more specific error during deserialization when a previously serialized job class is now unknown.

  ::ActiveJob::UnknownJobClassError will be raised instead of a more generic NameError to make it easily possible for adapters to tell if the NameError was raised during job execution or deserialization.
