ruby-on-rails – 为什么puma没有像Unicorn这样的`before_fork`

Unicorn配置有一个before_fork和after_fork方法断开连接,然后在fork之后重新建立连接.

然而,彪马没有那个.它只有on_worker_boot,它在概念上类似于after_fork方法.

Puma是否也利用工人流程的分支？在像Unicorn这样的分叉之前是否需要断开连接？

谢谢！

示例文件

配置/ unicorn.rb

before_fork do |server,worker|
  # other settings
  if defined?(ActiveRecord::Base)
    ActiveRecord::Base.connection.disconnect!
  end
end

after_fork do |server,worker|
  # other settings
  if defined?(ActiveRecord::Base)
    ActiveRecord::Base.establish_connection
  end
end

配置/ puma.rb

on_worker_boot do
  # Worker specific setup for Rails 4.1+
  # See: https://devcenter.heroku.com/articles/deploying-rails-applications-with-the-puma-web-server#on-worker-boot
  ActiveRecord::Base.establish_connection
end
