• Skip optimised #exist? query when #include? is called on a relation
  with a having clause

  Relations that have aliased select values AND a having clause that
  references an aliased select value would generate an error when
  #include? was called, due to an optimisation that would generate
  call #exists? on the relation instead, which effectively alters
  the select values of the query (and thus removes the aliased select
  values), but leaves the having clause intact. Because the having
  clause is then referencing an aliased column that is no longer
  present in the simplified query, an ActiveRecord::InvalidStatement
  error was raised.

  An sample query affected by this problem:

  Author.select('COUNT(*) as total_posts', 'authors.*')
        .joins(:posts)
        .group(:id)
        .having('total_posts > 2')
        .include?(Author.first)

  This change adds an addition check to the condition that skips the
  simplified #exists? query, which simply checks for the presence of
  a having clause.

  Fixes #41417

• Increment postgres prepared statement counter before making a prepared statement, so if the statement is aborted
  without Rails knowledge (e.g., if app gets kill -9d during long-running query or due to Rack::Timeout), app won't end

• Add override of unary plus for ActiveSupport::Duration.

  + 1.second is now identical to +1.second to prevent errors
  where a seemingly innocent change of formatting leads to a change in the code behavior.

  Before:

  +1.second.class
  # => ActiveSupport::Duration
  (+ 1.second).class
  # => Integer

  After:

  +1.second.class
  # => ActiveSupport::Duration
  (+ 1.second).class
  # => ActiveSupport::Duration

  Fixes #39079.

• Add subsec to ActiveSupport::TimeWithZone#inspect.

  Before:

  Time.at(1498099140).in_time_zone.inspect
  # => "Thu, 22 Jun 2017 02:39:00 UTC +00:00"
  Time.at(1498099140, 123456780, :nsec).in_time_zone.inspect
  # => "Thu, 22 Jun 2017 02:39:00 UTC +00:00"
  Time.at(1498099140 + Rational("1/3")).in_time_zone.inspect
  # => "Thu, 22 Jun 2017 02:39:00 UTC +00:00"
  

  After:

  Time.at(1498099140).in_time_zone.inspect
  # => "Thu, 22 Jun 2017 02:39:00.000000000 UTC +00:00"
  Time.at(1498099140, 123456780, :nsec).in_time_zone.inspect
  # => "Thu, 22 Jun 2017 02:39:00.123456780 UTC +00:00"
  Time.at(1498099140 + Rational("1/3")).in_time_zone.inspect
  # => "Thu, 22 Jun 2017 02:39:00.333333333 UTC +00:00"

• Align Range#cover? extension behavior with Ruby behavior for backwards ranges.

  (1..10).cover?(5..3) now returns false, as it does in plain Ruby.

  Also update #include? and #=== behavior to match.

• Update to TZInfo v2.0.0.

  This changes the output of ActiveSupport::TimeZone.utc_to_local, but
  can be controlled with the
  ActiveSupport.utc_to_local_returns_utc_offset_times config.

  New Rails 6.1 apps have it enabled by default, existing apps can upgrade
  via the config in config/initializers/new_framework_defaults_6_1.rb

  See the utc_to_local_returns_utc_offset_times documentation for details.

• [Breaking change] ActiveSupport::Callbacks#halted_callback_hook now receive a 2nd argument:

  ActiveSupport::Callbacks#halted_callback_hook now receive the name of the callback
  being halted as second argument.
  This change will allow you to differentiate which callbacks halted the chain
  and act accordingly.

    class Book < ApplicationRecord
      before_save { throw(:abort) }
      before_create { throw(:abort) }
  
      def halted_callback_hook(filter, callback_name)
        Rails.logger.info("Book couldn't be #{callback_name}d")
      end
  
      Book.create # => "Book couldn't be created"
      book.save # => "Book couldn't be saved"
    end
