글로벌 Ruby HTTP 시간 초과

Question

시간 초과 문제가 있습니다. sidekiq를 여러 스레드로 실행하고 있습니다. 각각은 일부 http 작업을 수행합니다. 때로는 작업자가 시간 제한을 두지 않고 Net HTTP 호출에 걸려들 때가 있습니다. 그런 다음 모든 스레드가 유휴 상태가되어 더 이상 아무것도하지 않습니다.

• 는 HTTP read_timeout은 루비 기본 open_timeout이 nil로 설정되는 반면, 60로 설정 될 것으로 보인다. 이것이 문제가 될 수 있습니까?
• 그렇다면 http 클래스의 모든 인스턴스에 대해 시간 초과의 기본값을 설정할 수 있습니까? 원숭이가 패치 해 줘?

I 원숭이는 HTTP 라이브러리를 패치. 문제가 다시 발생하는지 확실하지 않습니다. 그렇다면 여기에 게시 할 것입니다.

module Net 
    class HTTP < Protocol 
    alias_method :old_initialize, :initialize 

    def initialize(address, port = nil, open_timeout: 60) 
     old_initialize(address, port) 
     self.open_timeout = open_timeout 
    end 
    end 
end

업데이트에 게시 할 때 문제가있는 기본 시간 초과 값은 Net::HTTP입니다. Ruby 2.1.0의 경우 open_timeout의 기본값은 nil입니다. read_timeout은 기본적으로 60 초로 기본 설정됩니다.

Ruby 2.3부터 기본값은 open_timeouthas changed from nil to 60s입니다. Ruby 2.3은 처음에이 질문을한지 1 년 6 개월 만에 발표 될 예정 이었지만,이 문제를 경험하고있는 여러분이나 다른 분들에게 추천하는 방법은 Ruby 2.3 이상으로 업그레이드하는 것입니다. (가능한 경우 핵심 라이브러리를 monkeypatch하지 마십시오)
