[InterestManagement] in OpenSim.ini for experimental purposes.
If n > 1 for RootTerseUpdatePeriod only every n terse update is actually sent to observers on same region, unless velocity is effectively zero (to stop av drift).
If n > 1 for ChildTerseUpdatePeriod only every n terse update is sent to observers in other regions, unless velocity is effectively zero.
Defaults are same as before (all packets are sent).
Tradeoff is reduction of UDP traffic vs fidelity of observed av mvmt.
Increasing n > 1 leads to jerky observed mvmt immediateley for root, though not on child, where experimentally have gone to n = 4 before jerkiness is noticeable.

test purposes, and use more consise property syntax.
No functional change.

SP.WaitForUpdateAgent() with a triggered event instead.
Rapid polls are more expensive than triggered events (several polls vs one trigger) and may be problematic on heavily loaded simulators where many threads are vying for processor time.
A triggered event is also slightly quicker as there is no maximum 200ms wait between polls.
|
| |
|
|
| |
This is already going to be correctly set by WaitForUpdateAgent() earlier on in that method, which is always called where a callback to the originating region is required.
|
| |
|
|

actually meant to get an ack (because it's reliable).

an event rather than polling connection state every 100ms
This kind of polling is very expensive with many bots/polling threads and appears to be the primary cause of bot falloff from the client end at higher loads.
Where inbound packet threads can't run in time due to contention and simulator disconnect timeout occurs.
|
| |
|
|
|
| |
This adds the "show stats", "stats record", etc. commands and information on available Threadpool threads, etc.
It also adds the Watchdog which logs warnings if time between executions is unexpectedly large.

int.MaxValue
This is to avoid issues where many bots connect to a single end point with multiple regions, where each region requires a long-lived poll connection for each bot.
|
| |
|
|
| |
This is to resolve some issues for pCampbot, chiefly with capability connection and inbound handling.

It's WIP in that a dialog builder is on it's way. For now, the XML needs to

HGInventoryBroker to preserve that behaviour there but allow 2 simultaneous inv requests (chiefly WebFetch) rather than 1
This lock serialized all requests and made the inventory throttling in WebFetch redundant.
By moving this lock, two simultaneous requests may now take place which may help with http://opensimulator.org/mantis/view.php?id=7054

cuts down UDP traffic without obvious adverse effects on observed avatar rotations.
Experimentally, on the Linden Lab grid the avatar can rotate slightly before triggering AvatarUpdates, whereas this is practically impossible in OpenSimulator.
These updates allow other avatars to see rotations, though sensitivity is low since other avatars can only be seen in one of 8 body rotations.
This commit changes sensitivity from 0.01 to 0.1, which better matches LL and reduces UDP traffic which has a beneficial impact on network and CPU load.
This has no impact on rotations in the simulator itself so simulation fidelity is the same as before.
To change this setting back for test/other purposes, edit RootRotationUpdateTolerance in the [InterestManagement] section of OpenSim.ini

pool from 15 to 300
Running out of such threads under heavy load causes delayed packet processing which can lead to spurious UDP resends and knock on issues.
We already massively boost the min/max builtin pool worker and IOCP threads (which even with STP are still used for inbound network requests) without obvious adverse effects.
The threads are only instantiated if they are required.
This change does not affect other async_call_method options.

Move the experimental extra features functionality into the GridService. This sends default values for map, search and destination guide, plus ExportSupported control to the region on startup. Please watch http://opensimulator.org/wiki/SimulatorFeatures_Extras for changes and documentation.

RootVelocityUpdateTolerance parameters to [InterestManagement] in OpenSimDefaults.ini
These govern when AgentUpdates are sent to observers on position, rotation and velocity changes to an avatar (including the avatar themselves).
Higher values reduce AgentUpdate traffic but at a certain level will degrade smoothness of avatar and perceived avatar movement.

However, disconnecting now halts any current connection, with the possible exception of the single currently connecting bot.
|
| |
|
|

we can continue to run status commands whilst bots are disconnecting.

DebugLevel 1
This covers event queue setup messages and some outgoing messages (e.g. EnableSimulator)
In my experience these messages are only useful if you really know what they mean and you're looking for them
Otherwise, they're quite spammy.
Event queue DebugLevel 1 is enabled with the "debug eq 1" console command

not have sufficient permission, return null failure result rather than true.
On non-HG this is on the only recognized failure state so we can return more information in the error result.
On HG there are multiple failure states which would require more work to distinguish, so currently return the unsatisfying "Internal Error" like some other existing calls.

This should set the ServiceLocation to an empty string instead.

For experimental purposes.
Also corrects a previous bug where each terse update sent was counted rather than each set of terse updates to agents.

Allows experiments in manually reducing updates under heavy load.
Activated by "debug scene set client-upd-per" console command.
In a simple test, can send as few as every 4th update before observed movement starts becoming disturbingly rubber-banded.

Corresponds to ResendAppearnceUpdates setting in [Appearance] in OpenSim.ini
This was originally implemented to alleviate cloud appearance problems but could be too expensive with large numbers of avatars.

bulletsim physics is running in a separate thread.
This will also allow the "disable physics" setting in the region debug viewer dialog to work in this circumstance.

reprioritization distance to be changed on the fly.

This gives a count of all requests made to the remote inventory service.
This is finer grained than inventory.httpfetch.ProcessedFetchInventoryRequests since such a request can be comprised of many individual inv service calls.
In addition, this will count requests that don't go through the HTTP inventory fetch (e.g. HG, archiving, etc.)

Stop failure by actually giving the test handler a path instead of null

a huge number.
A stop gap solution - a better one may be to improve stats display on simulator-side.
Caps information is still accessible via the "show caps stats by user" and "show caps stats by cap" commands

This is for testing purposes (chiefly http://opensimulator.org/mantis/view.php?id=7054) so many not be permanent
Setting this will change the xinventory request timeout from the simulator from the default 100 seconds
|
| |
|
|
|
| |
For each service endpoint (e.g. posts to the xinventory service), a stat is available which shows the number of requests received and moving average per second
The full name is "service.<http-method>:<path>.requests (e.g. service.POST:/xinventory.requests)
