2. Detail description about this issue(error/log)

Why is the default value of dispatch_mode 3 and do you recommend using it?
When the value of dispatch_mode = 3 then
WARNING Server::start_check(): cannot set 'onClose' event when using dispatch_mode=1/3/7
That is, we will not be able to use onClose in websockets.
Do I understand correctly?
If I use websockets and I need onClose then I should use dispatch_mode = 2 right?

Thank you for your time!

For sync blocking HTTP Server, in order to use the Worker efficiently, it is recommended to set dispatch_mode=3. However, the onClose event cannot be supported under WebSocket Server. And Swoole will give you a WARNING message. If you do not need the onClose event, you can ignore it.

That is, we will not be able to use onClose in websockets.

If you want to use the onClose event, you can only set dispatch_mode=2/4/5
