[QUESTION] Regarding pongWait Time in the Examples

[eltfshr]

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior

In the examples, it seems like new read deadline is set after receiving pong:

ws.SetPongHandler(func(string) error { ws.SetReadDeadline(time.Now().Add(pongWait)); return nil })

My question is why is it not set right after ping is sent. This might be a misconception on my part, but shouldn't time-out be set after sending ping so that it waits for the responding pong? If it is set after receiving pong, then most of the time-out is wasted in between the interval of pings, and the real time left for new pong to respond is pongWait - pingPeriod.

Expected Behavior

I expected the time-out to be set when sending ping instead of receiving pong.

Steps To Reproduce

No response

Anything else?

I am just wondering about something and I will illustrate my confusion in the diagram below:

Is the Pong Wait not the specific time to wait after the server sends a ping to the client???
According to the implementation in the link below, we don't start the timer to count the timeout between ping periods.

I think this question has been sufficiently answered. Closing out
