limits because the only ones used now are the defaults (which are overwritten
by the client throttles anyway). Updated the default rates to correspond to
about 350kbps.
Also added a configuration to disable adaptive throttle. The default
is the previous behavior (no adaptation).
and currently used for all of an avatars attachments by the other
policies. Also changed the way items are pulled from the update queues
to bias close objects even more.
command to look at the entity update priority queue. Added a "name" parameter
to show queues, show pqueues and show throttles to look at data for a specific
user.
This should correct save all the assets required for the items within the coalesced objects in an IAR. This should also correctly gather the items on hypergrid takes.
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.
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.

It turns out that viewer 2 was upset by the lack of a response to viv_watcher.php. This would send it into a continuous login loop.
Viewer 1 was quite happy to ignore the lack of response.
This commit puts in the bare minimum 'OK' message in response to viv_watcher.php. This allows viewer 2 voice to connect and appears to work.
However, at some point we need to fill out the watcher response, whatever that is.
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.
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.
From pure code inspection, it looks like the uuid gatherer may get most asset uuids because the scene object serializer naively pulls non-root parts from all contained scene objects into one mega-object. However, root part uuids may well still be missing, and there may be other odd artifacts from this bug.
It appears that storing the size of the coalescence and the offsets is redundant, since one can work out this information from the position data already in the scene object groups.

OpenSim behavior is preserved by sending both.

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.
This now only happens for the first object (which was the item selected last when the coalesce was originally taken)
This matches the expected behaviour of the environment as seen on the Linden Labs grid.
This structure matches the existing one for SceneObjects and will allow code to be reused by the uuid gatherer, other tests, etc.
Test is not yet fully implemented due to a bug in rezzing coalesced objects where they all get the same name as the item.
Only one object should get the same name as the item, which appears to be the one selected last when the the objects were coalesced in the first place.
This bug will be addressed shortly.

This should happen if the client supplies a task ID with the RezObject call.
The rez goes through the same code as llRezObject(), so the same perms are applied.
Rotation isn't yet preserved, this should be fixed shortly.

Note that this is going to cause faster (and more) retransmissions. Fix
for dynamic throttling needs to go with this.
implement the display names functionality as such, but it allows scripts
that are display name aware to function as if the display name were implemented
and set to the avatar name.
This updates prim counts correctly if an object is moved by something other than an avatar (e.g. scripts, region modules)
Create TestMoveOwnerObject() regression test for this case.
However, the calls to the land management module to record prims need to remain, since they were also being used to return owner object lists, etc.
This is probably why prim counts were being done there in the first place.
This fixes the total prim count that the viewer displays when prims are selected - it appears to ignore the total that we pass it and adds up the counts separately.
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).
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!

WARNING!!!!!
You can TAKE them, but you can't REZ them again. Only the first of the contained
objects will rez, the rest is inaccessible until rezzing them is implemented.
Also, rotations are not explicitly stored. This MAY work. Or not.
