* I believe that if the Linden client has not started to receive a texture after 15 seconds, it re-requests it.
* My hypothesis is that the texture packets are often still in the texture queue (esp. if the client has just cleared its cache), so another load of packets get added...
* If this is the cause, resolution is going to be rather complicated.
* This may improve region memory usage
* This is a short-term response to a problem whereby some clients keep requesting the same texture even after we've sent it
* This treats the symptom rather than the cause.
* n can be adjusted by changing the constant at the top of UserTextureDownloadService if necessary
* When a new prim is created and raytracing is called for, raytrace from the camera position to the ground in the direction of the Norm(RayEnd - RayStart).
* If we got a hit based on our camera, create the new prim at the edge of the prim we hit.
* Don't raytrace if the difference between any component of the vector exceeds 4.5meters.
* We should not be using ASCII anywhere except for legacy compatibility reasons.
* A large number of UTF8 Encoders are being used in places where we should be using Util.StringToField instead. These have been tagged with // ENCODING FAULT
* This should fix Mantis#799 - Japanese Profile Text does not work.
* Should work in multi-region standalone and grid modes
* This should also solve other non-home region caps issues (map requests, RC client inventory requests, etc)
* We now pass CAPS information on to the destination region on region crossing, and set up a CAPS object when an agent becomes a master
* Current limitation is that this will only work if your http_listener_port is 9000
* This is a very early code cut (lots of bad practice, hard coding and inefficiency). However, I wanted to get this out there for feedback and my own sanity. Next few patches will clean up the mess.
* This reveals that the problem with saving scripts in a non-home region in multi-region configurations is due to a CAPS setup issue
* For some reason the client is still using the CAPS on the region it just came from, causing the ScenePresence lookup to fail (since the presence is now, correctly, a child agent).
* Remember, your admin user and estate managers can move locked objects that are not owned by them. That functionality differs from the Linden way of thinking and it's by design! It is not a bug! Create a non-god user and use that as your normal account.
* The warning will be
[USER TEXTURE DOWNLOAD SERVICE]: Received {0} requests for already dispatched texture {1} from client {2}
This is to see whether the texture packet queue memory leak is caused by clients continually re-requesting textures they should already have
* Should help stop any InvalidOperationExceptions caused by concurrent read/write
* The extra locking should be okay, but I'm really surprised we've got away without mucho crashes due to this...
Here's a diff of the changes I have made in support of the following LSL
script functions.
llSetScriptState
llGetScriptState
llCSV2List
llListRandomize
llList2ListStrided
llListFindList
llResetOtherScript
llGetScriptName
It was necessary to modify ExecutorBase in support of the ScriptState
implementations.
I also modified SceneObjectPart and SceneObjectPart.Inventory to
corrects a quoting mismatch in the commentary that through off live
parsing of the files.
I also simplified the State definition at the start of BuiltinCommands.
* Even very rapid linking/delinking should now behave normally. Terse updates still occur as before
* Hopefully this ends the recent linking problems - please let us know if there are more
* Noise, and Noise-Area brushes now use Perlin noise, more closely simulating the method LL uses officially.
* TerrainModule has been cleaned up slightly.
* TerrainUtil class has several new functions related to seeded noise generation.
* Extracted ITerrainEffect, ITerrainFloodEffect, ITerrainLoader, ITerrainPaintableEffect, TerrainChannel to seperate files.
* DelinkFromGroup was removing the parts from the delinked group, which later upset the update thread when it tried to do a queued update for that object
* Temporary fix is to stop deleting the parts, though it would be good later to stop sending out the now spurious updates
* This fix actually reveals another bug, where rapid linking and delinking will cause the non root prims to disappear (though they're actually still there if you relog). This is the next bug to tackle.
* Terrain Area-of-Effect brushes now should work properly.
* Updated the scale / effect of various brushes. Small & Medium brushes should now actually do something.
* Added osSetPrimFloatOnWater(BOOL) to make Physical prim float at the water level.
* osSetPrimFloatOnWater(TRUE); or osSetPrimFloatOnWater(FALSE);
* By default, prim do not float at the water level.
* More work is needed on the floating, but it's a start.
* W.I.P: Hydraulic Erosion (Spherical) paintbrush - code is all there, but some work is required on the initial parameters to get it to function correctly. Replaces the smooth brush when `newbrushes` is switched on.
* Implements the Optimised Erosion routine defined by Jacob Olsen in the paper 'Procedural Terrain Generation' (http://www.oddlabs.com/download/terrain_generation.pdf)
* Replaces the 'flatten' brush when 'newbrushes' is enabled.
* Added "script terrain newbrushes <true|false>" to enable experimental terraforming brushes. Presently the 'revert' brush is replaced with the Weathering brush, when enabled.
Also added osSetDynamicTextureDataBlend and osSetDynamicTextureURLBlend that will allow the various textures to be blended together, but currently there are still a few bugs in them. So not ready for use yet.
* Trying to store items other than textures, sounds and scripts in a prim's inventory should no longer cause an exception.
* Temporary solution is to ignore storage requests for these assets - actually implementing this requires changes to TaskInventoryItem, at least
* Enabled new TerrainModule. (The king is dead, long live the king!)
* Use the console command: "script terrain save file.r32" / "script terrain load file.r32" to load/save terrain. Now uses the extension to determine file format.
* MANY of the old terrain features do not have a replacement function in the new module yet, this needs to be corrected, but has not been done so far. This being said, the new module is faster and more efficient and should be a good replacement.
* *Much* faster terraforming (woot!)
* New "Brushes" design, so you can create custom terraforming brushes then apply those inplace of the standard tools. (ie an Erode Brush for example)
* New specialised "Flood Brushes" to do large area effects, ie, raise-area, now takes a bitmap rather than repeats the ordinary raise brush a thousand times.
* New modular file Load/Save systems -- write importers/exporters for multiple formats without having to hard code the whole thing in.
* Coming soon - effects system, ie the old Erosion functions, etc. for one-shot effects.
* ODE: Added support for larger box stacks. (they're slow, but they work)
* ODEPlugin no longer tries to 'catch up' with the simulator frame rate if it gets behind. Catching up was causing a lot of problems with larger box stacks and other things that stall the simulator (like saving prim in the datastore)
appropriate names consisten with their use.
All done with all 94 handlers from handler001
through handler094. Hopefully we can move
forward without numbered handlers.
* To play with this you must link your prim before setting it physical, otherwise they won't link in the physics engine properly. This will also be fixed.
* Currently the linked prim are extremely unstable because I have yet to implement combining of forces with the same normal. This will also be fixed. In fact, the whole PhysicsActor, ODEPrim relationship will be reworked to consider groups from the get-go.
* This implementation is better then it crashing your sim, so I'm commiting it for now.
** Added more realistic calculations of mass for the rest of the supported prim shapes+holes+cuts+tapers. Previously they were the generic height * width * length. Spheres roll (Angular velocity) more realistically, etc.
So anyway, it moves the Asset downloading (packet sending) to a module (AssetDownloadModule).
So now at last, AssetCache should be just dealing with fetching assets from the asset server and caching them.
* This might stop some client's constant requests for unfound textures, which is a candidate for the memory leak
* If a texture is not found then the "Image not found" texture will now be displayed clientside
* If it works, this should resolve mantis 676
* Non texture image requests do not receive this packet yet
* This will require a prebuild
* When you select a physical prim, it stops while you've got it selected.
* When you move or alter a prim in some manner, it doesn't become collidable until you de-select it
* When you select a prim, it doesn't become temporarily 'phantom' until you make some change to it while it's selected. (this prevents accidental selections in prim floor from causing it to go phantom on you(but don't move it or you'll fall))
* There's one major difference, and that's a physical object won't stop if you don't have permission to edit it. This prevents people who don't have edit permissions on a prim from stopping it while it's moving.
* Resolve a bad logic bug in AssetCache.GetAsset()
* This may make some asset related things work better (possibly getting main map images will now be improved).
* This should stop the constant increase in the download requests statistics
* If you see stat numbers for download requests which are far from what you'd expect, please report
* This fixes some of the 'runaway downloads' problem but not all of it
* Also fix up logging messages so texture requests are reported as such rather than as assets
* Untangled a tangly shutdown loop for the ScenePresence.
* Suggested to the Garbage Collector that this may be a good time to >.>, <.< *gasp* collect the memory.
* Set the massively slow UpdateEntities method to run every 2 seconds instead of 10 times a second. This method runs through *all* of the entities can calls the virtual update().
* Documented some of the code in the scene.Update method.
* The reason why pending downloads tick ever upwards is because missing assets are never signalled to the TextureSender
* Rectifying this is not straightfoward, but this will constitute the next patch.
* This does not explain the memory leak.
In his own words:
If a prim becomes a listener or remote channel and the script is deleted, it cannot become a listener or channel again with a new script.
This patch fixes that.
Changed the public IsAdministrator back to protected,
now checks Config to see whether it is allowed to run or not.
Defaults to false (not allowed).
To use add the following to OpenSim.ini
[LL-Functions]
AllowosConsoleCommand=true
* Converted all instances of "256" spotted to use RegionSize instead. Some approximations used for border crossings (ie 255.9f) are still using that value, but should be updated to use something based on RegionSize.
* Moving Terrain to a RegionModule, implemented ITerrainChannel and TerrainModule - nonfunctional, but will be soon.
appearance in the TryGetAvatarAppearance() method. Moving off Add will mean the second replaces the first instead of throwing the exception. This may still not be a good
permanent solution - more extensively locking or a code rearrangement could be better. I'm going to leave this in MW's much more familiar hands now.
all TerrainEngine.LoadFromFileX(string filename) methods don't set the dirty bits in heightmap.diff[,] in contrast to the TerrainEngine.LoadFromFileX(string filename, int dimensionX, int dimensionY, int lowerboundX, int lowerboundY) cousins. this has the unpleasant drawback that the Scene.SendTerrainUpdate(bool) will not send layer data to the client.
the attached patch fixes all LoadFromFileX(.) methods.
Thanks!
* Also small build fix for AvatarFactoryModule
* Updated the ode.dll for windows with a more reasonable stack space reserve. Linux users will need to type ulimit -s 262144 before starting up OpenSimulator if using Physical Prim to protect against stack collisions. or run the included ./bin/opensim-ode.sh to start up OpenSimulator in ODE mode.
* Added internal collision score and am keeping track of 'high usage' prim.
* Tweaked collisions some more
* Tested up to 460 physical prim in extremely close quarters (which was previously impossible in OpenSim). After 460 in tight quarters, physics slows down enough to make it hard to do any moving, however.. non physics things still work, such as logging on to the simulator, etc.
* Push asset update (invoked when clothing is altered) down into AgentAssetTransactions from Scene.Inventory.cs to join others
* I've tested that clothing creation and update still works, but please let me know if it suddently breaks for you.
* Add/correct comments
** Sending the actual TimeDilation to the client now instead of the 62455 constant. The client is *supposed* to use that value to sync with the simulator. (actually sending ushort.maxvalue * TimeDilation)
** Disabling prim that inter-penetrate instead of just not attaching a joint
** Reduced prim spin a 'little' bit, but not *enough*
** Tweaked the TimeDilation algorithm to be closer to 1.0 by default and various changes to the sim stats reporter
** Created a .SetValues method to PhysicsVector so we can simply call the setvalues function instead of .x, .y, .z sets.
** Experimented with a .GetBytes Method on PhysicsActor to be able to use the LLVector3.FromBytes() method.
** Upped the Inter-penetration depth to 0.25 instead of .08.
Added experimental console command to:
* unload module (note: module probably doesn't support it)
* load module
Not visible in help (needs testing first).
** Created SendFullUpdateToAllClientsExcept(LLUUID) so that permission updates /appear/ to apply immediately
** Separated out the ObjectFlags and the Permission Flags. They're related but not the same
** Added a hack routine to add *back* the objectflags to the client flags because the client hates the way we're doing object permissions
** Updated the clientflags routine to properly tell the client when they can't edit admin objects (objects owned by the sim administrator) even when they're an estate manager(why? >.< argh!)
** Fixed a null sim administrator/estate manager/user from causing permissions to return false even when it should return true.
** Re-added ObjectModify hack to allow collaboration with the allow anyone to move checkbox until we get group permissions done.
* Made Estate tools work for estate managers without needing to request admin status First
* Added code to make the Simulator version to be reported in the About box of the client
* However, I'm no longer sure they were even a big contributory factor (to this particular leak, there are other causes of other leaks). I need better measurement techniques
* Removed most of my debugging gawp
Attached is a patch for Mantis 25 - this fixes the problem of not having a
touch_start happen for all prims in a linked group. So, with this, large
builds can now have a single script in the base prim and it will run when
any prim in the linked build is touched. The problem was that the
objectgrab event was not being propagated to all the prims in the group.
* ParcelProperties are sent only when needed instead of on any movement
* Terse Updates and other temporary data packets are marked unreliable
* After a certain amount of users, the sim actually sends updates on things less
* Experimental
* Tested to 68 avatar with pCampBot (And it's surprising what actually causes the most lag.. the text chat!)
To use, see the appearance section in opensim.ini.example, set "persist = true", then add the correct connection string for your database.(see mysql-AvatarAppearance.sql in share folder for a example of the table mysql table structure).
This could possible be used in a very small grid, but would mean each region server would need to connect to the same mysql database.
But the work to move the code to one of the grid servers shouldn't be too much.
The ScriptDialogReply packet handler is a bit of a hack job. It is currently handled similar to ChatFromViewer, which will trigger the listen() event, however this is not exactly how LL's implementation works and will/can be fixed up later.
* Added a method for Tedd to hook to in scene to disable the Scripting engine that currently says, [TOTEDD] Here is the method to trigger disabling of the scripting engine.
* If you have Debian running, you should get a platform line that says, 'Found Debian!' when starting up your sim.
* If someone running Debian will confirm this does occur, that would be most helpful.
** If the region fails 3 times, then ChildAgentDataUpdates no longer get sent to that region
* Enabled Child_Get_Tasks in grid mode.
* When Child_Get_Tasks is enabled on neighbor regions, the neighbor region uses the client's draw distance to send out prim. This is a lot less likely to flood the client now since the ChildAgentDataUpdate contains both the throttle settings and the draw distance. This means that with this enabled, you can see prim in other regions in grid mode. Very experimental.
* On restart the latest save will be restored rather than the very first dragged in scripts
* Also add previously missed out database commits to separate prim inventory commit path (sigh)
* Added a Logout message with a name on the console
* Added a *fixme* message to figure out why the current agent session is null
* After updating you may notice that there's a login <user> and also a logout<user>
* Set the avatar's radius to 0.37m, I think this gives the *best* balance between spaces the avatar can fit, and the ability to climb steps
* Fixed a few things
* Tweaked some more
* Played with gravity (-9.8m/s)
* An example changed event syntax is at: http://opensimulator.org/wiki/Changed_Event_Example
* You can use this to trigger actions in your script if someone sits on your object_rez
* You can use this to figure out all of the CHANGED_ constants except for CHANGED_REGION, CHANGED_TELEPORT, and CHANGED_ALLOW_DROP
* Fixed a bunch of goofy math for calculating the sim stats counters
* Made most of the sim stats counters additive so it's easy to change the sim stats interval
* Changed the sim stats send interval to 3 seconds
* This means that you can take an object from a region and rez it somewhere else, with its inventory intact.
* As for earlier, at this stage only scripts can be placed in inventory
* This isn't an efficient implementation, a better one will probably need to come along soonish
* Time dilation is off now.. because it's the additive of the 0.91 * 10 (adds a second) / 5( the number of seconds since the last update) which results in 0.41td as common
* Slowing down the network accounting update will probably fix the red issue.
* We're only missing, the script related sim stats counters and the Images time counter and the Pending Uploads counter. The rest of them are actually implemented now.
* Added frame Milliseconds, Physics Milliseconds and Other Milliseconds to the Sim Stats Reporter so we can start to figure out what the slowdowns are. (these were the most convenient to get and had just about no overhead.
* Linkset status is now persistent
* Tweaked a physics child prim positioning hack to generate less database saves
* Re-factored physics object creation calls into ApplyPhysics. To create a new physics representation of an object or linkset, it's only necessary to call *group*.ApplyPhysics(bool m_physicalPrim). *lbsa has been waiting for this refactoring*
* We have collidable linksets now. (they don't become phantom anymore)
* Cleaned up copyright notices in AssemblyInfo.cs's
* Added Copyright headers to a bunch of files missing them
* Replaced several common string instances with a static constant to prevent reallocation of the same strings thousands of times. "" -> String.Empty is the first such candidate.
* There will be bugs, you can count on that. To avoid them, set the linksets phantom
* After region restart, the linksets restore in a non collidable state.
* Linksets can but shouldn't be made physical with the physical checkbox or when you unlink them, they tend to explode.
* After creating a linkset, you have to move the linkset or set it phantom and not phantom for it to become collidable.
* There's a few ParentGroup references that need to be refactored.
* Did some goofy math undoing in the Sim Stats Reporter
* More reduction to the amount of calls per second to UnManaged ODE code
* Added a significant amount of comments to ODE
300 msecs can be too slow and cause a timeout to occur. This is reported when
llHTTPRequest times out but may not be reported for other functions like
osSetDynamicTextureURL. This sets the time out to 30 seconds. It appears
that the value affects not just llHTTPRequest's.
* This can be turned on by setting storage_prim_inventories_experimental = True in OpenSim.ini
* Implemented for sqlite and MySQL, no MSSQL implementation yet
* As an experimental feature, there is no guarantee that this won't take down your region or that the db representation won't need to change.
* More (and continuing) details at http://opensimulator.org/wiki/OpenSim:Prim_Inventory_Persistence
* It is now possible to edit and save scripts directly from prim inventories
* On saving, the script will be restarted in the region
* Doesn't appear that it's yet possible to drag inventory contents back to agent inventory. Not quite sure why this is yet - the perms all look very permissive.
Probably doesn't yet work for any items other than scripts.
Still some work to do. No user functionality exposed. Not yet user tieable into normal code.
* Estate managers get abilities like the region owner for now.
* Estate managers, you'll need to request server admin status to be able to activate the estate tools dialog (haven't figured out why this is the case yet)
* Switching from grid mode to standalone or switching grids will make the stored Estate Manager UUIDs not match up with a valid account so you'll see (waiting) listed there instead of a user until you reset them or go back to the grid you added them from.
* You can put UUIDs in those fields to give other users some ability to help manage a sim you own.
* Also started decoding the EstateOwnerMessage packet convolutions.
* The BlockingQueue exposes Contains so we can make sure we don't add a TextureSender to the queue if there's already one present
* introduced some TryGetValue and various code convention stuff
* You can add and remove a friend in grid mode now within the same simulator. It doesn't save yet.
* I got rid of Mr. OpenSim as a friend.. he bothers me /:b...
* Charles, this will fix the red issue.
* Same situation, the first run updates the tables (and gives you a ton of red errors), the second run and everything works as expected.
* PrimitiveBaseShape: The textures are now exposed as a 'TextureEntry Textures'; all serialization still using the 'byte[] TextureEntry' for backwards compatibility.
* Scene: Re-added AddTree, since the Tree type isn't gone from libsl, merely relocated.
* SAVE YOUR PRIM DATA, THIS MAKES CHANGES TO YOUR PRIMS TABLE
* The first time you run OpenSim after updating past this revision, you'll see a lot of Errors. Be calm, shutdown the simulator, and start it again and your prims table will be updated.
* MSSQL added the fields to the Initial CreateTable section, however, you'll need to add the fields to your prims table if you want it to persist.
