Rails 5.1.0.alpha

  • 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::StatementInvalid, 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::StatementInvalid when a local db deadlock is detected
        # Might raise Net::OpenTimeout when the remote service is down
      end
    end
