Question

我们遇到了一些超时问题。我们正在使用多线程运行sidekiq。他们每个人都执行一些http操作。有时，工作人员陷入Net HTTP调用，而不会超时。然后所有线程都空闲，什么都不做。

http read_timeout似乎设置为60，而ruby默认open_timeout设置为nil。这可能是问题吗？
如果是，是否可以为http类的所有实例设置超时的默认值？猴子补丁吗？

修改

我修补了http库。不确定问题是否会再次发生。如果是，我会在这里发布。

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

问题在于您在更新中发布的Net::HTTP中的默认超时值。对于Ruby 2.1.0，open_timeout的默认值为nil。 read_timeout安全默认为60秒。

从Ruby 2.3开始，open_timeout has changed from nil to 60s的默认值。在您最初提出这个问题之后，Ruby 2.3将不会再发布一年半，但我向您或遇到此问题的任何人提出的建议是升级到Ruby 2.3或更高版本。（而不是monkeypatch核心库，如果可能的话）
