如何调试由工头开始的rails（3.2）应用程序？ [英] How to debug a rails (3.2) app started by foreman?

问题描述

我正试图用工头来启动我的rails应用程序。不幸的是，连接我的IDE进行调试时遇到困难。

我阅读了此处使用

  Debugger.wait_connection = true 
 Debugger.start_remote 
  pre> 
 
 
启动远程调试会话，但这并没有真正解决。
 
 
 
 问题： 
有没有办法调试由工头开始的rails（3.2）应用程序？如果是这样，那么这个方法是什么？
解决方案
如果你使用几个具有完整的rails环境的工作人员，可以使用下面的初始化器： / p> 
 
 
 ＃启用与工头的调试器，请参阅https://github.com/ddollar/foreman/issues/58 
 if Rails.env.development？ 
 require'debugger'
 Debugger.wait_connection = true 
 
 def find_available_port 
 server = TCPServer.new（nil，0）
 server.addr [1 ] 
确保
 server.close如果服务器
结束
 
 port = find_available_port 
将远程调试器在端口＃{port}
 Debugger.start_remote（nil，port）
 end 
  
在工头的日志中，你会可以找到调试器的端口：
  $ foreman start 
 12:48:42 web.1 |以pid 29916开始
 12:48:42 worker.1 |以pid 29921开始
 12:48:44 web.1 | I，[2012-10-30T12：48：44.810464＃29916] INFO  - ：listen on addr = 0.0.0.0：5000 fd = 10 
 12:48:44 web.1 |我，[2012-10-30T12：48：44.810636＃29916] INFO  - ：刷新宝石列表
 12:48:47 web.1 |端口59269上的远程调试器
 12:48:48 worker.1 |端口41301上的远程调试器
  
现在运行调试器：
  rdebug -c -p [PORT] 
  
 
I am trying to use foreman to start my rails app. Unfortunately I have difficulties connecting my IDE for debugging. 

I read here about using
Debugger.wait_connection = true
Debugger.start_remote
to start a remote debugging session, but that does not really work out.

Question:
Is there a way to debug a rails (3.2) app started by foreman? If so, what is the approach?
解决方案
If you use several workers with full rails environment you could use the following initializer:
# Enabled debugger with foreman, see https://github.com/ddollar/foreman/issues/58
if Rails.env.development?
  require 'debugger'
  Debugger.wait_connection = true

  def find_available_port
    server = TCPServer.new(nil, 0)
    server.addr[1]
  ensure
    server.close if server
  end

  port = find_available_port
  puts "Remote debugger on port #{port}"
  Debugger.start_remote(nil, port)
end
And in the foreman's logs you'll be able to find debugger's ports:
$ foreman start
12:48:42 web.1     | started with pid 29916
12:48:42 worker.1  | started with pid 29921
12:48:44 web.1     | I, [2012-10-30T12:48:44.810464 #29916]  INFO -- : listening on addr=0.0.0.0:5000 fd=10
12:48:44 web.1     | I, [2012-10-30T12:48:44.810636 #29916]  INFO -- : Refreshing Gem list
12:48:47 web.1     | Remote debugger on port 59269
12:48:48 worker.1  | Remote debugger on port 41301
Now run debugger using:
rdebug -c -p [PORT]
