will open quickly up to the maximum specified by the client and/or

This still needs a lot of adjustment to get the rates correct.

mechanism as the entity update queues.
|
|
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.

of property update should supercede another. But for now the old

become significant when selecting/deselecting large numbers of
objects.
This is experimental code.

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.

Reprioritization algorithms need to be ported still. One is

synchronously.
Handling these synchronously kills the inbound packet loop if many requests are made for remote land and those requests are handled slowly or timeout (timeout is 10s)
This can happen if a user searches for "land for sale" and then clicks many of the parcels in the list (or just presses down arrow to move through every entry).

changes to all the estates that the user owns).
This applies to adding/removing estate users, groups, managers and bans.
This is the application of the AllEstates_0.5.patch from http://opensimulator.org/mantis/view.php?id=5420
Thanks very much, Snoopy!

Also adds lots of temproarily debug logging

the server settings.
This is in a very crude state, currently.
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

* Added Calculating Time Dilation in the OdePlubin
* When multiple object updates are stuffed into one packet, average the time dilation between them as a compromise.
* Time Dilation on the update is calculated when the EntityUpdate object is created. The pre-calc-ed TD is stored in the Entity update and used when it goes out on the wire. Previously, it was 1.0 all the time. The time dilation is tied to when the update is created, not when the update is sent.

* Adds an item that checks to see if the top request has been there for longer then 30 seconds without an update and sends an AbortXfer if it encounters one. This allows the client to cancel the Xfer on it's side so you can re-select the prim and get the inventory when it fails the first time.
* Some interesting locking... Using NewFiles to lock the rest of them. We'll see how that goes.
* The goal of this is to ensure that Xfers are restartable when they fail. The client will not do that on it's own.

These locks are necessary to avoid a delete/update race condition for scene objects.
However, since we're now locking on m_killRecord this shouldn't cause delays to m_entityUpdates reprioritization

updates for self movement as absolute top priority, going in to the unthrottled category. Self only, not other avies.
