ruby - 法拉第 : you may want to install system_timer for reliable timeouts

Question

我将一个旧脚本迁移到一个新的 CentOS box 并在运行脚本时收到以下消息:

Faraday: you may want to install system_timer for reliable timeouts

它是警告吗？system_timer 是什么？ gem ？

Answer 1

这是一颗 gem 。

不过，您应该不再需要它了，因为它只支持 Ruby 1.8 及更早版本(Ruby 1.8 已正式弃用)。

来自 http://ph7spot.com/musings/system-timer :

Update: system_timer is only relevant if you are running Ruby 1.8. You do not need it if you are running Ruby 1.9, JRuby, Rubinius or MacRuby. Actually using system_timer with one of these Ruby interpreters would not even make any sense since, as explained in this article, system_timer is designed to workaround a fundamental limitation of the threading implementation in Ruby M.R.I. 1.8 (green threads). All other Ruby interpreters use native threads and timeout.rb should work as expected as long as the global interpreter lock is released.
