Bug #9380: Enumerator does not work in timeout

• Status: Closed
• Assignee: nobu (Nobuyoshi Nakada)

Enumeratorとtimeoutの組み合わせで、Timeout::Errorが起きるべきところでArgumentErrorが発生します。

$ ruby -v -rtimeout -e 'def (o=Object.new).each; sleep; end' -e 'Timeout.timeout(0.01) {o.to_enum.next}'
ruby 2.2.0dev (2014-01-07 trunk 44522) [universal.x86_64-darwin13.0]

lib/timeout.rb: fallback to Timeout::Error

• lib/timeout.rb (Timeout::ExitException.catch): pass arguments
  for new instance.
• lib/timeout.rb (Timeout::ExitException#exception): fallback to
  Timeout::Error if couldn't throw. [ruby-dev:47872] [Bug #9380]
• lib/timeout.rb (Timeout#timeout): initialize ExitException with
  message for the fallback case.
