activerecord 5.2.4

on Ruby Gems

Active Support

• Make ActiveSupport::Logger Fiber-safe. Fixes #36752.

  Use Fiber.current.__id__ in ActiveSupport::Logger#local_level= in order
  to make log level local to Ruby Fibers in addition to Threads.

  Example:

  logger = ActiveSupport::Logger.new(STDOUT)
  logger.level = 1
  p "Main is debug? #{logger.debug?}"
  
  Fiber.new {
    logger.local_level = 0
    p "Thread is debug? #{logger.debug?}"
  }.resume
  
  p "Main is debug? #{logger.debug?}"
  

  Before:

  Main is debug? false
  Thread is debug? true
  Main is debug? true
  

  After:

  Main is debug? false
  Thread is debug? true
  Main is debug? false

Active Model

  Fixes #35676.

Active Record

• Fix circular autosave: true causes invalid records to be saved.

  Prior to the fix, when there was a circular series of autosave: true
  associations, the callback for a has_many association was run while
  another instance of the same callback on the same association hadn't
  finished running. When control returned to the first instance of the
  callback, the instance variable had changed, and subsequent associated
  records weren't saved correctly. Specifically, the ID field for the
  belongs_to corresponding to the has_many was nil.

  Fixes #28080.

  Larry Reid

• PostgreSQL: Fix GROUP BY with ORDER BY virtual count attribute.

  Fixes #36022.

  Ryuta Kamizono

• Make ActiveRecord ConnectionPool.connections method thread-safe.

  Jeff Doering

• Assign all attributes before calling build to ensure the child record is visible in
  before_add and after_add callbacks for has_many :through associations.

  Fixes #33249.

Action View

• Allow programmatic click events to trigger Rails UJS click handlers.
  Programmatic click events (eg. ones generated by Rails.fire(link, "click")) don't specify a button. These events were being incorrectly stopped by code meant to ignore scroll wheel and right clicks introduced in #34573.
