* Requeue unacknowledged entity updates rather than resend then "as is".Dan Lake2011-04-191-32/+32
| | | | | | | | | | | | | | | | | | | | | | | | 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.
* New tokenbucket algorithm. This one provides fair sharing of the queuesMic Bowman2011-04-121-1/+1
| | | | | | | | | when client and simulator throttles are set. This algorithm also uses pre-defined burst rate of 150% of the sustained rate for each of the throttles. Removed the "state" queue. The state queue is not a Linden queue and appeared to be used just to get kill packets sent.

The LindenUDPModule was renamed LindenUDPInfoModule and moved to OptionalModules OptionalModules was given a direct reference to OpenSim.Region.ClientStack.LindenUDP so that it can inspect specific LindenUDP settings without having to generalize those to all client views (some of which may have no concept of the settings involved). This might be ess messy if OpenSim.Region.ClientStack.LindenUDP were a region module instead, like MXP, IRC and NPC

| * Stop LLUDPServer sending updates after object deletes by always queueing deletesJustin Clark-Casey (justincc)2010-12-021-2/+6
| | | | | | | | | | | | | | | | If an LL 1.23.5 client (and possibly earlier and later) receives an object update after a kill object packet, it leaves the deleted prim in the scene until client relog This is possible in LLUDPServer if an object update packet is queued but a kill packet sent immediately. Beyond invasive tracking of kill sending, most expedient solution is to always queue kills, so that they always arrive after updates. In tests, this doesn't appear to affect performance. There is probably still an issue present where an update packet might not be acked and then resent after the kill packet.

| * Set async_packet_handling = true by defaultJustin Clark-Casey (justincc)2010-10-301-1/+1
| | | | | | | | | | | | Setting this to true avoids a 500ms or so client freeze when the LLUDP server thread is taken up with processing a UseCircuitCode packet synchronously. Extensive testing on Wright Plaza appeared to show no bad effects and this seems to reduce login lag considerably. Of course, a lot of login lag is still coming from other sources.

* Send KillPackets on the Task queue rather than the State queueJustin Clark-Casey (justincc)2010-09-171-0/+4
| | | | | | | | | Object updates are sent on the task queue. It's possible for an object update to be placed on the client queue before a kill packet comes along. The kill packet would then be placed on the state queue and possibly get sent before the update If the update gets sent afterwards then client get undeletable no owner objects until relog Placing the kills in the task queue should mean that they are received after updates. The kill record prevents subsequent updates getting on the queue Comments state that updates are sent via the state queue but this isn't true. If this was the case this problem might not exist.
