Subject: [ruby-core:43227] [ruby-trunk - Bug #6128][Rejected] Thread#run does not work within signal handler


Issue #6128 has been updated by Koichi Sasada.

Status changed from Open to Rejected

trap handler (registered block) run on main thread.  So Thread#run for main thread doesn't work.

You should use other ways to communicate trap handler and main thread, for example, Queue.

  $q = Queue.new
  trap(:INT){$q.push nil}
  
  ...
  $q.pop # wait for trap handler

If I stop Thread.main, calling Thread.main.run in a signal handler does not wake up the main thread.

Please see this gist with a simple reproducible example:
