bquorning / flatten.rb
Created February 19, 2018 20:53
Did Ruby 2.5 introduce a new bug, or fix an old bug? The implicit `flatten` -> `to_ary` -> `respond_to_missing` call has changed.
class A
def respond_to?(method, include_all = false)
::Kernel.puts "respond_to?(#{method.inspect}, #{include_all.inspect})"
end
end
class B
def respond_to_missing?(method, include_all = false)
::Kernel.puts "respond_to_missing?(#{method.inspect}, #{include_all.inspect})"
end

Reproduction script for https://github.com/rspec/rspec-rails/issues/1668
# Run this script with `ruby rspec-rails-json-controller-params.rb`
# It will spawn two processes: one using Minitest, one using RSpec.

Models using `store` to serialize a `Hash` in the form of `ActionController::Parameters` in Rails 4 cannot read that same column in Rails 5.

ActiveRecord trying to save readonly records on has_many_through assignment. It looks like the bug was introduced by https://github.com/rails/rails/commit/d849f42b4ecf687ed5350f5a2402fb795aa33aac, and it should probably check `if !record.readonly?` and not just remove the condition.

Run with `rspec action_controller_gem.rb`. Fails as it is, but works with https://github.com/rspec/rspec-rails/pull/1568 applied.
