Updated by yahonda (Yasuo Honda) 6 months ago
### Steps to reproduce 1. Install `ruby 3.3.0dev` 2. Set `RUBY_MN_THREADS=1` environment variable 3. Follow these steps ``` git clone https://github.com/rails/rails cd rails rm Gemfile.lock bundle install cd actioncable bin/test test/channel/base_test.rb test/subscription_adapter/redis_test.rb test/channel/test_case_test.rb test/subscription_adapter/redis_test.rb test/client_test.rb --seed 14800 ``` ### Expected behavior It should pass as not setting ``` $ unset RUBY_MN_THREADS $ bin/test test/channel/base_test.rb test/subscription_adapter/redis_test.rb test/channel/test_case_test.rb test/subscription_adapter/redis_test.rb test/client_test.rb --seed 14800 /home/yahonda/.rbenv/versions/trunk/lib/ruby/gems/3.3.0+0/gems/minitest-5.20.0/lib/minitest.rb:3: warning: mutex_m which will no longer be part of the default gems since Ruby 3.4.0.

Finished in 12.031310s, 6.0675 runs/s, 46.7115 assertions/s. 73 runs, 562 assertions, 0 failures, 0 errors, 0 skips $ ``` ### Actual behavior It usually fails as follows. ``` $ bin/test test/channel/base_test.rb test/subscription_adapter/redis_test.rb test/channel/test_case_test.rb test/subscription_adapter/redis_test.rb test/client_test.rb --seed 14800 /home/yahonda/.rbenv/versions/trunk/lib/ruby/gems/3.3.0+0/gems/minitest-5.20.0/lib/minitest.rb:3: warning: mutex_m which will no longer be part of the default gems since Ruby 3.4.0.
