ruby-on-rails - 从 ruby​​ 守护进程中调试 osascript 执行

Question

我需要经常在我的网络服务器上运行 applescript。由于服务器正在运行 rails，并且我需要在运行脚本之前和之后访问我的模型，我认为守护进程(通过 daemons gem )可能是合适的。

理论上这很容易。下面是一个简化的例子。

#!/usr/bin/env ruby

ENV["RAILS_ENV"] ||= "development"

require File.dirname(__FILE__) + "/../../config/application"
Rails.application.require_environment!

$running = true
Signal.trap("TERM") do 
  $running = false
end

while($running) do

  Rails.logger.info "Daemon running at #{Time.now}.\n"

  # sanity check
  %x{touch /foo.txt}

  # this stops working after a while
  result = %x{/usr/bin/osascript -s o /path/to/the/script.scpt}

  # under normal operation, my applescript spits out a string result
  Rails.logger.info "Result: #{result}.\n"

  sleep 30
end

出于测试目的，我用一行代码替换了(有点长且耗时的)生产 applescript。这是它的全部荣耀:

"It Worked!"

因为 applescript 将脚本的最后一行视为返回语句，所以该字符串被传递到我的 result 变量中并最终登录到 rails 中。

这在一段时间内效果很好。但最终(通常在几个小时后)osascript 行停止返回结果。守护程序仍在 仍在运行，但据我所知，osascript 行完全失败，没有任何解释。

我可以肯定地说，守护进程本身并没有死，因为

• rails 日志条目以正确的时间间隔出现，并且
• 我对“foo.txt”的合理性检查会定期更新其最后修改的时间戳。

我想我会发布一个更新，以防有人遇到类似的问题。首先，我找到了解决方法。这肯定是一个丑陋的 hack，但它完成了工作并且不会每 2 小时崩溃一次。我正在做的是在每次运行作业时建立一个 ssh 连接，这有效地让脚本在一个干净的 session 上运行。

Net::SSH.start('127.0.0.1', 'username', :password => 'password') do |ssh|
  result = ssh.exec!('/usr/bin/osascript -s o /path/to/the/script.scpt') 
end

其次，我在 ~/Library/Logs/DiagnosticReports 目录中发现了大量崩溃报告。越来越多的我开始相信这整个考验与某种 session 超时或过期有关。

Answer 1

我通过测试发现了我们的问题。我有一个问题要问你，你是如何开始剧本的？它是从登录机器并在 Mac OSX 桌面屏幕中启动终端启动的吗？或者您是通过 ssh 连接到 Mac 并从那里启动它。

在我们尝试使用窗口管理器 (firefox) 的守护程序上，如果我们通过登录用户的 Terminal.app 启动它。它会工作得很好。如果我们 ssh 进入以启动脚本(当您使用 Capistrano 启动它时会发生这种情况)它会正常工作，直到该 ssh session 停止。在控制台中，您可以看到日志:

2/7/11 8:32:13 PM    com.apple.SecurityServer[22]    Session 0x22058d0 destroyed
2/7/11 8:32:13 PM    com.apple.SecurityServer[22]    Session 0x22058d0 dead
2/7/11 8:32:13 PM    com.apple.SecurityServer[22]    Killing auth hosts

这发生在我们终止 SSH session 之后。终止后，我们会像您一样收到错误:

abort() called
LaunchServices: GetOurLSSessionIDInit() returned err #1, 
    securitySessionID == 0x0, vers=10600000 uid=501 euid=501

我们现在有一个 LaunchAgent，而不是通过 ssh 启动脚本，它将基于带有 ~/jobs/目录的 WatchPaths 启动脚本。它运行良好，我们仍然可以使用 capistrano 重新启动服务器。

我会在您的日志中查看 SecurityServer 是否在脚本失败时立即销毁 session 。如果是这样，那么也许您可以找出导致超时的原因。
