rails--rails/activejob/CHANGELOG.md

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
