rails/activejob/CHANGELOG.md

• Fix BigDecimal (de)serialization for adapters using JSON.

  Previously, BigDecimal was listed as not needing a serializer. However, when used with an adapter storing the job arguments as JSON, it would get serialized as a simple String, resulting in deserialization also producing a String (instead of a BigDecimal).

  By using a serializer, we ensure the round trip is safe.

  To ensure applications using BigDecimal job arguments are not subject to race conditions during deployment (where a replica running a version of Rails without BigDecimalSerializer fails to deserialize an argument serialized with it), ActiveJob.use_big_decimal_serializer is disabled by default, and can be set to true in a following deployment..

  Sam Bostock

• Preserve full-precision enqueued_at timestamps for serialized jobs, allowing more accurate reporting of how long a job spent waiting in the queue before it was performed.

  Retains IS08601 format compatibility.

  Jeremy Daer

• Add --parent option to job generator to specify parent class of job.

  Example:

  bin/rails g job process_payment --parent=payment_job generates:

  class ProcessPaymentJob < PaymentJob
    # ...
  end
  

  Gannon McGibbon

• Add more detailed description to job generator.

  Gannon McGibbon

• perform.active_job notification payloads now include :db_runtime, which is the total time (in ms) taken by database queries while performing a job. This value can be used to better understand how a job's time is spent.

  Jonathan Hefner

• Update ActiveJob::QueueAdapters::QueAdapter to remove deprecation warning.

  Remove a deprecation warning introduced in que 1.2 to prepare for changes in que 2.0 necessary for Ruby 3 compatibility.

  Damir Zekic and Adis Hasovic

• Add missing bigdecimal require in ActiveJob::Arguments

  Could cause uninitialized constant ActiveJob::Arguments::BigDecimal (NameError) when loading Active Job in isolation.

  Jean Boussier

• Allow testing discard_on/retry_on ActiveJob::DeserializationError

  Previously in perform_enqueued_jobs, deserialize_arguments_if_needed was called before calling perform_now. When a record no longer exists and is serialized using GlobalID this led to raising an ActiveJob::DeserializationError before reaching perform_now call. This behavior makes difficult testing the job discard_on/retry_on logic.

  Now deserialize_arguments_if_needed call is postponed to when perform_now is called.

  Example:

  class UpdateUserJob < ActiveJob::Base
    discard_on ActiveJob::DeserializationError
  
    def perform(user)
      # ...
    end
  end
  
  # In the test
  User.destroy_all
  assert_nothing_raised do
    perform_enqueued_jobs only: UpdateUserJob
  end
