When using WindowedRequestTracking, if the enquire_link expires, the bind is closed but doesnt restart

[laduchesneau]

The OnExpiredPduRequest is using the transceivable.go Close() function. This uses the ExplicitClosing state. Therefor the OnClosed() and the session restart() functions are not called.

if t.settings.OnExpiredPduRequest != nil {
    bindClose := t.settings.OnExpiredPduRequest(request.PDU)
    if bindClose {
        _ = t.Close()
    }
}

The normal behavior when any PDU expires, the user should be is given the choice to restart the bind by returning true to the closeBind variable. When its requested, the ConnectionIssue state should be used.

if t.settings.OnExpiredPduRequest != nil {
    bindClose := t.settings.OnExpiredPduRequest(request.PDU)
    if bindClose {
        t.closing(ConnectionIssue)
    }
}

func (t *transceivable) closing(state State) {
    if atomic.CompareAndSwapInt32(&t.aliveState, Alive, Closed) {
        t.in.closing(StoppingProcessOnly)
        t.out.closing(StoppingProcessOnly)

        // close underlying conn
        _ = t.conn.Close()

        // notify transceiver closed
        if t.settings.OnClosed != nil {
            t.settings.OnClosed(state)
        }
    }
    return
}

Hi, is this related to issue #154 problem?

[laduchesneau]

No. its for #152. This issue does not impact OnAllPdu configs.
