* | | | minor: Eliminate more unnecessary code copying individual parameters for ↵Justin Clark-Casey (justincc)2014-08-281-17/+19
| | | | | | | | | | | | | | | | Vector3 copying in Scene - this is not necessary as Vector3 is a value type
* | | | On code section that rezzes single objects and attachments, reduce CPU use ↵Justin Clark-Casey (justincc)2014-08-285-71/+128
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | by reading asset XML a single time with a stream reader rather than multiple times. Reading large XML documents (e.g. complex attachments) is CPU expensive - this must be done as few times as possible (preferably just once). Reading these documents into XmlDocument is also more resource intensive than using XmlTextReader, as per Microsoft's own publication "Improve .NET Application Performance and Scalability" Optimization of other cases will follow if this change is successful.

* | | | Implement experimental non-default mechanism to update scene via a timer ↵Justin Clark-Casey (justincc)2014-08-264-67/+113
| |_|/ |/| | | | | | | | | | | | | | | | | | | | rather than a persistent thread with sleep. This is to see if an inaccuracy in sleep times under load is responsible for increase in frame times even when there is spare time still available. Can currently only be activated by setting "debug scene set update-on-timer true". Can be switched between timer and thread with sleep updates whilst the scene is running.
* | | Remove database connection locking in MySQLXAssetData. This is unnecessary ↵Justin Clark-Casey (justincc)2014-08-221-186/+168
| | | | | | | | | | | | as connections aren't shared and transactions are already in place where necessary.

* | | Remove some use of database connection locking from MySQLSimulationData - ↵Justin Clark-Casey (justincc)2014-08-221-318/+298
| | | | | | | | | | | | | | | | | | | | | | | | | | | this has not been necessary for some time as database connections are not shared. However, many locks remain since they may effectively be providing transactionality in some operations (e.g. prim updates across multiple tables). These are candidates for being replaced with proper database transactions, since this would not block unrelated operations (e.g. land save and object save) or unrelated operations on the same tables (e.g. storage of one linkset whilst another is being removed). In practice, any performance deg due to contention is probably rare and short lived as the major prim operations are performed in memory and only persisted some time afterwards.
* | | Remove lock in MySQLFramework. This is not necessary as the connection is ↵Justin Clark-Casey (justincc)2014-08-221-21/+12

| |/ |/| | | | | | | | | These locks are not necessary since the connection is taken from the underlying mysql pool and not shared. Such locking is already not done by some other parts of OpenSim.Data.MySQL. Pointed out by arribasim-dev
* | Extend drop command to "debug lludp drop <in|out>..." to allow drop of ↵Justin Clark-Casey (justincc)2014-08-192-8/+44
| | | | | | | | | | | | inbound packets. For test/debug purposes.
* | Add "debug lludp drop out <add|remove> <packet-name>" console command for ↵Justin Clark-Casey (justincc)2014-08-192-0/+76
| | | | | | | | | | | | | | debug/test purposes. This drops all outbound packets that match a given packet name. Can currently only be applied to all connections in a scene.
* | minor:Give console feedback when we sit or stand pCampbot bots.Justin Clark-Casey (justincc)2014-08-191-2/+16
| | | | | | | | Also only write console lines for actually connected bots.
* | Add clientstack.<scene>.OQRERequestsWaiting statJustin Clark-Casey (justincc)2014-08-191-0/+19
| | | | | | | | Only present if OQRE is enabled
* | Add experimental OutgoingQueueRefillEngine to handle queue refill processing ↵Justin Clark-Casey (justincc)2014-08-193-5/+288
| | | | | | | | | | | | | | | | | | | | | | on a controlled number of threads rather than the threadpool. Disabled by default. Currently can only be enabled with console "debug lludp oqre start" command, though this can be started and stopped whilst simulator is running. When a connection requires packet queue refill processing (used to populate queues with entity updates, entity prop updates and image queue updates), this is done via Threadpool requests. However, with a very high number of connections (e.g. 100 root + 300 child) a very large number of simultaneous requests may be causing performance issues. This commit adds an experimental engine for processing these requests from a queue with a persistent thread instead. Unlike inbound processing, there are no network requests in this processing that might hold the thread up for a long time. Early implementation - currently only one thread which may (or may not) get overloaded with requests. Added for testing purposes.
* | Make LLUDPServer.Scene publicly gettable/privately settable instead of ↵Justin Clark-Casey (justincc)2014-08-193-49/+55
|/ | | | | | | protected so that other logging code in the clientstack can record more useful information Adds some commented out logging for use again in the future. No functional change.

* Don't allow the last behavior to be removed from a pCampbot botJustin Clark-Casey (justincc)2014-08-152-1/+4
| | | | If you want to stop existing behavious, add the None behaviour.
* Resolve a small race condition on removing bot behaviours that might leave ↵Justin Clark-Casey (justincc)2014-08-151-2/+3
| | | | | | | previous behaviour active Also closes behaviours on disconnect instead of interrupt, though this makes no practical difference. If existing behaviour is None, other added behavious will not take affect until None is removed (as this is an infinite wait until interrupted).
* If a user moves back in sight of a child region before the agent has been ↵Justin Clark-Casey (justincc)2014-08-153-7/+9
| | | | closed on teleport, don't unnecessarily resend all avatar and object data about that region.
* On teleport to a region that already has a child agent established (e.g. a ↵Justin Clark-Casey (justincc)2014-08-157-39/+50
| | | | | | neighbour) don't resend all the initial avatar and object data again. This is unnecessary since it has been received (and data continues to be received) in the existing child connection.
* Added RestrictEmail to make llEmail only send to avatars email address if true.Kevin Cozens2014-08-141-0/+34

* Make RootTerseUpdatePeriod and ChildTerseUpdatePeriod configurable in ↵Justin Clark-Casey (justincc)2014-08-141-0/+3
| | | | | | | | | | [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.
* Make some existing reprioritization values changeable outside the scene for ↵Justin Clark-Casey (justincc)2014-08-141-15/+18
| | | | | | test purposes, and use more consise property syntax. No functional change.
* Update OpenID server handler with proper interface. fixes ↵BlueWall2014-08-131-1/+1
| | | | http://opensimulator.org/mantis/view.php?id=7301
* On entity transfer of scene presence, replace polling sleep in ↵Justin Clark-Casey (justincc)2014-08-131-14/+13
| | | | | | | 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.
* Remove redundant origin region lock in SP.CompleteMovement()Justin Clark-Casey (justincc)2014-08-131-6/+1
| | | | 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.
* Only set up the UnackedMethod for an outgoing message if that message is ↵Justin Clark-Casey (justincc)2014-08-131-1/+3
| | | | actually meant to get an ack (because it's reliable).
* Terminate 'nothing' behaviour (and potentially others) by signalling using ↵Justin Clark-Casey (justincc)2014-08-135-36/+56
| | | | | | | 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.
* Add 'server' stats information to pCampbot, as used elsewhere in OpenSimulatorJustin Clark-Casey (justincc)2014-08-132-0/+25
| | | | | 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.
* For pCampbot, set max number of permitted connections to an endpoint to ↵Justin Clark-Casey (justincc)2014-08-121-0/+4
| | | | | | 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.
* Avination's Dynamic Floater Module. This works with Singularity viewer only.Melanie Thielker2014-08-122-0/+290
| | | | | It's WIP in that a dialog builder is on it's way. For now, the XML needs to be handmade.
* Move the inventory request lock introduced in git master a58152bd to ↵Justin Clark-Casey (justincc)2014-08-092-27/+47
| | | | | | | 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
* Change RootRotationUpdateTolerance from 0.01 to 0.1 in code as well.Justin Clark-Casey (justincc)2014-08-081-1/+1

* Add RootPositionUpdateTolerance, RootRotationUpdateTolerance, and ↵Justin Clark-Casey (justincc)2014-08-061-0/+7
| | | | | | | 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.
* refactor: Rename recent new Client*UpdateTolerance to Root*UpdateTolerance ↵Justin Clark-Casey (justincc)2014-08-063-19/+19

* Go back to disconnecting bots in parallel since serially is too slow.Justin Clark-Casey (justincc)2014-08-051-3/+5
| | | | However, disconnecting now halts any current connection, with the possible exception of the single currently connecting bot.
* Put pCampbot "disconnect" command on separate thread like "connect" so that ↵Justin Clark-Casey (justincc)2014-08-051-27/+35
| | | | we can continue to run status commands whilst bots are disconnecting.
* Allow "show bots" pCampbot console command to quickly report status by not ↵Justin Clark-Casey (justincc)2014-08-051-18/+20

| | | | | | | | | 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

* If REMOVEAGENTFROMGROUP core groups call fails because requesting agent does ↵Justin Clark-Casey (justincc)2014-07-314-10/+22
| | | | | | | 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.
