Subject: -1 shutdown_timeout?
To: yahns-public@yhbt.net

Hi,

I am trying to switch one application from using rainbows
to yahns, and the application would do some long-polling.

When I ctrl+c to interrupt yahns, I would see yahns is
trying to drop clients which still connect, with timeout
set to 5 (from my config setting client_timeout to 5).

However, after a few seconds, there would be messages
like this from yahns:

    dropping 0 of 1 clients for timeout=-1

The timeout would be -1 after a few seconds, and then
it would only stop when those clients timeout at 60 seconds
(this is my assumption though, it would show a request was
 around 60 seconds from CommonLogger (assumption again)
 in the end, and yahns would quit gracefully)

I looked around the code, which should be:

  def dropping(fdmap)
    if drop_acceptors[0] || fdmap.size > 0
      timeout = @shutdown_expire < Yahns.now ? -1 : @shutdown_timeout
      fdmap.desperate_expire(timeout)
      true
    else
      false
    end
  end

While Yahns.now would get growing, I don't really understand why
it's written like this? Is this intentional? If so, how could I force
yahns shut those clients down in this case?

Thanks!
