Question

我通过工头启动独角兽，因此吞下了调试器提示符。我过去曾debugger宝石幸运connecting as a remote debugger。

我们即将升级到Ruby 2.1.2，据我所知，它与debugger不兼容。

我已将远程调试器代码更改为使用byebug：

require 'byebug'

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}"
Byebug.start_server('localhost', port)

一旦启动了独角兽，我可以连接到byebug：

$ byebug -R localhost:54623
Connecting to byebug server localhost:54623
Connected.

但我的代码中充斥着byebug次调用，并且它们永远不会在远程调试器中触发断点。远程连接时，调试器未正常远程加载时阻塞的页面。

unicorn文件只指定一个工作者，所以我有理由相信它不是它：

require File.dirname(__FILE__)+'/application'

if Rails.env.development?
  worker_processes 1
  timeout_override = ENV['WEBSERVER_TIMEOUT_OVERRIDE']
  timeout Integer(timeout_override || 3600)
  if timeout_override
    puts "Development: Using WEBSERVER_TIMEOUT_OVERRIDE of #{timeout_override} seconds"
  end
else
  worker_processes Integer(ENV['WEB_CONCURRENCY'] || 3)
  timeout 25
end

preload_app true

before_fork do |server, worker|

  Signal.trap 'TERM' do
    puts 'Unicorn master intercepting TERM and sending myself QUIT instead'
    Process.kill 'QUIT', Process.pid
  end

  defined?(ActiveRecord::Base) and
      ActiveRecord::Base.connection.disconnect!
end

after_fork do |server, worker|

  Signal.trap 'TERM' do
    puts 'Unicorn worker intercepting TERM and doing nothing. Wait for master to send QUIT'
  end

  defined?(ActiveRecord::Base) and
      ActiveRecord::Base.establish_connection
end

非常感谢任何想法。

我认为你错过了一个简单的设置： Byebug.wait_connection = true

更改此

port = find_available_port
puts "Remote debugger on port #{port}"
Byebug.start_server('localhost', port)

到这个

port = find_available_port
puts "Remote debugger on port #{port}"
Byebug.wait_connection = true
Byebug.start_server('localhost', port)

这应该是神奇的。希望它有所帮助。

ByeBug遥控器不会与Unicorn一起打破断点
