* Added an "immediate" queue to the priority queue. This isMic Bowman2011-04-201-245/+0
| | | | | | | | | per Melanie's very good suggestion. The immediate queue is serviced completely before all others, making it a very good place to put avatar updates & attachments. Moved the priority queue out of the LLUDP directory and into the framework. It is now a fairly general utility.
* Adds the first pass at an adaptive throttle to slow start newMic Bowman2011-04-204-18/+95
| | | | | | | | clients. If the sent packets are ack'ed successfully the throttle will open quickly up to the maximum specified by the client and/or the sims client throttle. This still needs a lot of adjustment to get the rates correct.

* Requeue unacknowledged entity updates rather than resend then "as is".Dan Lake2011-04-193-54/+112
| | | | | | | | | | | | | | | | | | | | | | | | Often, by the time the UDPServer realizes that an entity update packet has not been acknowledged, there is a newer update for the same entity already queued up or there is a higher priority update that should be sent first. This patch eliminates 1:1 packet resends for unacked entity update packets. Insteawd, unacked update packets are decomposed into the original entity updates and those updates are placed back into the priority queues based on their new priority but the original update timestamp. This will generally place them at the head of the line to be put back on the wire as a new outgoing packet but prevents the resend queue from filling up with multiple stale updates for the same entity. This new approach takes advantage of the UDP nature of the Linden protocol in that the intent of a reliable update packet is that if it goes unacknowledge, SOMETHING has to happen to get the update to the client. We are simply making sure that we are resending current object state rather than stale object state. Additionally, this patch includes a generalized callback mechanism so that any caller can specify their own method to call when a packet expires without being acknowledged. We use this mechanism to requeue update packets and otherwise use the UDPServer default method of just putting expired packets in the resend queue.
* Remove the call to remove tokens from the parent. Under heavy loadMic Bowman2011-04-152-5/+14
| | | | | | | | | | this appears to cause problems with the system timer resolution. This caused a problem with tokens going into the root throttle as bursts leading to some starvation. Also changed EnqueueOutgoing to always queue a packet if there are already packets in the queue. Ensures consistent ordering of packet sends.
