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.
types of property updates to be specified. Not sure if one form
of property update should supercede another. But for now the old
OpenSim behavior is preserved by sending both.
to the entity update queue. The number of property packets can
become significant when selecting/deselecting large numbers of
objects.
This is experimental code.
In order to pass ILandObject into IClientAPI.SendLandProperties(), had to push ILandObject and IPrimCounts into OpenSim.Framework from OpenSim.Region.Framework.Interfaces, in order to avoid ci
Counts are showing odd behaviour at the moment, this will be addressed shortly.
* 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.
Remove the too coarse CanEditParcel method in favor of a CanEditParcelProperties
method that takes a GroupPowers argument to specify what action is to be
taken. Also, make the method to set parcel data much more granular. Permissions
in a deeded setting should now work.
AvatarService -- add two new methods, GetAppearance and SetAppearance
to get around the lossy encoding in AvatarData. Preseve the old
functions to avoid changing the behavior for ROBUST services.
AvatarAppearance -- major refactor, moved the various encoding
methods used by AgentCircuitData, ClientAgentUpdate and
ScenePresence into one location. Changed initialization.
AvatarAttachments -- added a class specifically to handle
attachments in preparation for additional functionality
that will be needed for viewer 2.
AvatarFactory -- removed a number of unused or methods duplicated
in other locations. Moved in all appearance event handling from
ScenePresence. Required a change to IClientAPI that propogated
throughout all the IClientAPI implementations.
* Simplified the interest management code to make it easier to add new policies. Prioritization and reprioritization share code paths now
* Improved the distance and front back policies to always give your avatar the highest priority
Fixes: Undo, T-pose of others on login, modifiedBulletX works again, feet now stand on the ground instead of in the ground, adds checks to CombatModule. Adds: Redo, Land Undo, checks to agentUpdate (so one can not fall off of a region), more vehicle parts. Finishes almost all of LSL (1 function left, 2 events).
Direct flames and kudos to Revolution, please

* Handle logout properly. This needed an addition to IClientAPI, because of how the logout packet is currently being handled -- the agent is being removed from the scene before the different event handlers are executed, which is broken.
InventoryDescendents packet. Testing has shown that UDP inventory now
works flawlessly and, unlike CAPS inventory, doesn't download the entire
agent inventory on start. Neither does it incessantly re-request folder
NULL_KEY. Therefore, I have disabled CAPS inventory.
* Changed the Send*Data structs in IClientAPI to use public readonly members instead of private members and getters
* Made Parallel.ProcessorCount public
* Started switching over packet building methods in LLClientView to use Util.StringToBytes[256/1024]() instead of Utils.StringToBytes()
* More cleanup of the ScenePresences vs. ClientManager nightmare
* ScenePresence.HandleAgentUpdate() will now time out and drop incoming AgentUpdate packets after three seconds. This fixes a deadlock on m_AgentUpdates that was blocking up the LLUDP server
* Handle the AgentFOV packet
* Bypass queuing and throttles for ping checks to make ping times more closely match network latency
* Only track reliable bytes in LLUDPCLient.BytesSinceLastACK
* Changed the ClientManager interface to reduce potential errors with duplicate or mismatched keys
* Added IClientAPI.RemoteEndPoint, which can (hopefully) eventually replace IClientAPI.CircuitCode
* Changed the order of operations during client shutdown
* Removed the confusing (and LL-specific) shutdowncircuit parameter from IClientAPI.Close()
* Updated the LLUDP code to only use ClientManager instead of trying to synchronize ClientManager and m_clients
* Remove clients asynchronously since it is a very slow operation (including a 2000ms sleep)
Fixing LLClientView memory leak by disposing of all timers utilized
in LLClientView as they contain references to the callback method.
This required the use of the Terminate and Close infrastructure that
was already in place but was not being utilized.
* Inspect incoming TextureEntry updates for bakes that do not exist on the simulator and request the missing textures
* Properly handle appearance updates that do not have a TextureEntry set
