I’m working on supporting Ruby 3 and got this spec failure. Steps to reproduce Run Ruby 3.0.2 $ cd discourse $ bundle exec rspec spec/models/optimized_image_spec.rb:10 Expected result It should finish successfully as follows 1 example, 0 failures Actual result It always get failure as follows. $ bundle exec rspec spec/models/optimized_image_spec.rb:10 Run options: include {:locations=>{"./spec/models/optimized_image_spec.rb"=>[10]}} Randomized with seed 44957 F Failures: 1) OptimizedImage.crop should produce cropped images (requires ImageMagick 7) Failure/Error: expect(cropped_size).to be ' # ./spec/rails_helper.rb:279:in `block (2 levels) in ' Finished in 0.22966 seconds (files took 2.89 seconds to load) 1 example, 1 failure Failed examples: rspec ./spec/models/optimized_image_spec.rb:10 # OptimizedImage.crop should produce cropped images (requires ImageMagick 7) Randomized with seed 44957 $ Diag info This failure is related to this line. lib/image_optim/cmd.rb 1ed032858 # Run using `system` # Return success status # Will raise SignalException if process was interrupted def run(*args) if args.last.is_a?(Hash) && (timeout = args.last.delete(:timeout)) args.last[Gem.win_platform? ? :new_pgroup : :pgroup] = true pid = Process.spawn(*args) waiter = Process.detach(pid) if waiter.join(timeout) status = waiter.value check_status!(status) status.success? else cleanup(pid, waiter) fail Errors::TimeoutExceeded end When it runs with Ruby 2.7.4 it works but with Ruby 3.0.2 it raises “can’t convert ImageOptim::Timer into Float (TypeError)”. Here are the minimum steps to reproduce. $ more foo.rb gem 'image_optim' require 'image_optim' timeout = ImageOptim::Timer.new(15.0) args = [{"PATH"=> "/usr/bin"}, "date" ] pid = Process.spawn(*args) waiter = Process.detach(pid) waiter.join(timeout) With Ruby 3.0.2, it shows “can’t convert ImageOptim::Timer into Float (TypeError)” $ ruby -v ruby 3.0.2p107 (2021-07-07 revision 0db68f0233) [x86_64-linux] $ ruby foo.rb foo.rb:14:in `join': can't convert ImageOptim::Timer into Float (TypeError) from foo.rb:14:in ` ' Fri Oct 1 12:42:51 PM JST 2021 $ With Ruby 2.7.4 it works with no exception. $ ruby -v ruby 2.7.4p191 (2021-07-07 revision a21a3b7d23) [x86_64-linux] $ ruby foo.rb Fri Oct 1 12:44:00 PM JST 2021 $

Thanks for the suggestion. Sure. Will open a pull request to GitHub - toy/image_optim: Optimize images using multiple utilities · GitHub .

OptimizedImage specs are failing with Ruby 3.0.2

Looks like there is a trivial fix there … just add a .to_f

if waiter.join(timeout.to_f)

Can you send a PR through?
