Время ожидания вызова Ruby on Rails для сценария Perl

Question

Я пишу приложение на Ruby on Rails, которое вызывает Perl-скрипт с использованием Open3. Однако при вызове perl-скрипта мое приложение вызывает Timeout:: Error раньше, чем я хочу. Код, где я вызываю скрипт, выглядит так:

  Timeout::timeout(120){
       @stdout, @stderr, @exit_code  = Open3.capture3(@command)
      [@exit_code.to_i, @stdout, @stderr]
  }

Я понимаю, что вызов потенциально "долго" работающего скрипта (возможно, 20–30 секунд) не идеален для приложения ruby ​​on rails, но у меня не так много вариантов.

Я использую единорога, чтобы получить параллелизм, и у меня установлен тайм-аут единорога 60 с. Несмотря на 60-секундный тайм-аут в моем файле единорога и 120-секундный тайм-аут, обернутый вокруг вызова Open3, мой запрос истекает примерно на 18 секунд. Я знаю, что сценарий успешно завершается, потому что вижу результаты на другой стороне, но мне нужно мое приложение, чтобы дождаться возвращения сценария.

Есть ли другой способ заставить мое приложение rails ждать, а не тайм-аут?

Спасибо!

Как вы можете видеть в трассировке стека

/opt/sen/ruby/lib/ruby/gems/1.9.1/gems/rack-timeout-0.0.3/lib/rack/timeout.rb:16:in `call'

у вас есть промежуточное программное обеспечение стойки (время ожидания стойки), которое вызывает дополнительное время ожидания для всего запроса. Сконфигурируйте или удалите это промежуточное ПО, и все будет в порядке.
