Description

A gem with a temporary stopgap workaround for MRI Ruby versions 2.2.7, 2.2.8, 2.3.4, 2.4.1 for the bug https://bugs.ruby-lang.org/issues/13632 until the proper fix gets backported. No other versions besides those 4 are affected. The mentioned versions are currently most recent ones.

How does this bug look?

You're getting a similar exception erratically in a presence of many threads:

Traceback (most recent call last):
    1: from test2.rb:9:in `block (2 levels) in <main>'
test2.rb:9:in `sysopen': stream closed in another thread (IOError)

Installation and usage

In Gemfile:

if %w(2.2.7 2.2.8 2.3.4 2.4.1).include? RUBY_VERSION
  gem "stopgap_13632", "~> 1.0", :platforms => ["mri", "mingw", "x64_mingw"]
end

Don't forget to require it:

require 'stopgap_13632'

And when an "IOError: stream closed" happens in a thread, accessing a busy IO, catch it and call the following method:

rescue IOError
  Thread.current.purge_interrupt_queue
end

It will unblock the thread and allow it to proceed.
