[英]Ruby daemon hangs on rails load
I am having issues getting a workling daemon working correctly. 我在使工作守护程序正常工作时遇到问题。 When I run: 当我跑步时:
ruby script/workling_client run
the daemon starts to load rails, but hangs indefintely. 守护程序开始加载rails,但是不确定地挂起。 When I kill the process, the stack trace is always the same: 当我终止进程时,堆栈跟踪总是相同的:
/Library/Ruby/Gems/1.8/gems/activesupport-2.1.2/lib/active_support/core_ext/load_error.rb:32:in `new': Interrupt

from script/workling_client:18
If I run the script without the daemons library, it works as expected. 如果我在没有守护程序库的情况下运行该脚本,则它将按预期工作。 I have, in fact, had trouble using the daemon gem to load anything that requires my rails environment. 实际上,我在使用守护程序gem加载需要我的rails环境的任何东西时遇到了麻烦。 Any ideas? 有任何想法吗?
UPDATE: The workling_client loads worklings listen.rb as a daemon. 更新:workling_client将工作文件listen.rb加载为守护程序。 Instead of loading rails in listen.rb, I changed it so that it gets loaded in workling_client instead, and the process works without a hitch. 我没有将其加载到listen.rb中,而是对其进行了更改,以便将其加载到workling_client中,并且该过程可以顺利进行。 Therefore, there is some reason that I can't load rails in a daemonized script :-( 因此,出于某些原因,我无法在守护程序脚本中加载rails :-(
Can you post the code that starts the daemon script? 您可以发布启动守护程序脚本的代码吗? I know it is possible to load rails in a daemons script since we do it for our delayed_jobs script. 我知道可以在daemons脚本中加载rails,因为我们是为delay_jobs脚本完成的。
The initial part of the script does: 该脚本的初始部分执行以下操作:
require File.expand_path(File.join(File.dirname(__FILE__), '..', 'config',
'environment'))
adjust for your environment.rb file in your rails project. 在Rails项目中针对您的environment.rb文件进行调整。 Then, the process proceeds to daemonize itself: 然后,该过程继续守护自己:
Worker::Command.new(ARGV, :workers => worker_config).daemonize
Our script loads rails before doing the daemonize step. 我们的脚本在执行守护进程之前先加载rails。 If this doesn't work, include how your script loads rails. 如果这不起作用,请包括脚本如何加载rails。
Try start working without monitor: 尝试在没有监视器的情况下开始工作:
options = {
:app_name => "workling",
:ARGV => ARGV,
:dir_mode => :normal,
:dir => File.join(File.dirname(__FILE__), '..', 'log'),
:log_output => true,
:multiple => false,
:backtrace => true,
:monitor => false
}
