* Changed the throttling logic to obey the requested client bandwidth limit but also share bandwidth between some of the categories to improve throughput on high prim or heavily trafficked regions
Replaced the update lists with a priority queue implementation in LLClientView.
The priority queues are based on the MinHeap implementation also included in
this commit within the OpneSim.Framework namespace. Initially setup to exactly
mimic the behavior beofre the change which was a first come first serve queue.
* Removed two redundant parameters from SceneObjectPart
* Changed some code in terse update sending that was meant to work with references to work with value types (since Vector3 and Quaternion are structs)
* Committing a preview of a new method for sending object updates efficiently (all commented out for now)
* Apparently the LLClientView should have been doing this previously.. Also fixed the 'You' on the index block.. so the client doesn't display an extra green dot.
* Thanks lkalif for bringing it to our attention.
* OnQueueEmpty is still called async, but will not be called for a given category if the previous callback for that category is still running. This is the most balanced behavior I could find, and seems to work well
* Added support for the old [ClientStack.LindenUDP] settings (including setting the receive buffer size) and added the new token bucket and global throttle settings
* Added the AssetLoaderEnabled config variable to optionally disable loading assets from XML every startup. This gives a dramatic improvement in startup times for those who don't need the functionality every startup
* Changed the way the QueueEmpty callback is fired. It will be fired asynchronously as soon as an empty queue is detected (this can happen immediately following a dequeue), and will not be fired again until at least one packet is dequeued from that queue. This will give callbacks advanced notice of an empty queue and prevent callbacks from stacking up while the queue is empty
* Added LLUDPClient.IsConnected checks in several places to prevent unwanted network activity after a client disconnects
* Prevent LLClientView.Close() from being called twice every disconnect
* Removed the packet resend limit and improved the client timeout check
* Added some missing implementations of IClientAPI.RemoteEndPoint
* Added a ClientManager.Remove(UUID) overload
* Removed a reference to a missing project from prebuild.xml
* 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)
* Move ViewerEffect handling to Scene.PacketHandlers
* Removing the unused CloseAllAgents function
* Trimming ClientManager down. This class needs to be reworked to keep LLUDP circuit codes from intruding into the abstract OpenSim core code
* Changing OpenSimUDPBase back to high concurrency. High concurrency mode seems to make other problems happen faster, so it's helpful for working out other bugs and will probably

* Clients are no longer disconnected when a packet handler crashes. We'll see how this works out in practice
* Added documentation and cleanup, getting ready for the first public push
* Deleted an old LLUDP file
* Replaced logic in ThreadTracker with a call to System.Diagnostics that does the same thing
* Added Util.StringToBytes256() and Util.StringToBytes1024() to clamp output at byte[256] and byte[1024], respectively
* Fixed formatting for a MySQLAssetData error logging line
* Shrinks the largest in-memory object, the LLRAW.HeightmapLookupValue struct (only used for exporting to LLRAW terrain files), to the minimum possible size. This seems to have the odd side effect of cutting the size of the two double[256,256] terrain objects in half. Possibly an alignment optimization?
* Moved all priority queue access to helper functions to improve reliability and readability
* New version of CSJ2K.dll (from libomv source tree) that fixes a JPEG2000 comment decoding bug
* Fixed the incorrect "out of memory?" exception messages and replaced them with useful information
* Cleaned up J2KImage and LLImageManager to conform to coding conventions
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
* Re-added openjpeg-dotnet files since they are used elsewhere in OpenSim * Updated prebuild.xml with a reference to CSJ2K
* Renamed IJ2KDecoder and J2KDecoder member names to follow standard naming conventions * Removed j2kDecodeCache cruft and replaced it with the OpenSim cache system * Rewrote the default layer boundary algorithm to use percentages instead of an exponent * Switched from an infinite in-memory cache to an expiring cache (10 minute timeout) * Slightly quieted logging errors for failed texture decodes
* LongVersion nIni may be causing the test thread death. Pausing OpenSimulator during startup causes a nIni error that makes debugging startup operations difficult for users. It might be because when it's in pause mode, something else reads from the nini config passed? If it is, it might not be fixable.. however, if it's concurrency that causes nini death it would make sense to give each section of the tests a new IConfigSource so that they don't read from the same configsource at the same time.
* Test for prim obstructions between the avatar and camera. If there are obstructions, inform the client to move the camera closer. This makes it so that walls and objects don't obstruct your view while you're moving around. Try walking inside a hollowed tori. You'll see how much easier it is now because your camera automatically moves closer so you can still see.
* Created a way to know if the user's camera is alt + cammed or just following the avatar.
* Changes IClientAPI interface by adding SendCameraConstraint(Vector4 CameraConstraint)
This involved adding a new OnUpdatePrimSingleRotationPosition event to IClientAPI so that we can get the changed position from the client.
Btw adding new events to IClientAPI is really tedious where you have to copy the change across to at least 5 or 6 other files.
[Note this doesn't fix the bug where any rotation changes to the root prim (but not the whole linkset) cause rotation errors on the child prims.]
balancer plugin work again. Create a new method, GetClientEP, to retrieve
only the EndPoint for script usage. Marked the purpose of the method
in IClientAPI.cs with a warning. Also restored the corresponding SetClientInfo
functionality.
to be constantly pushed and popped uselessly, if you are not debugging packets. This showed some really big difference in a mock test, let's see how it behaves here.
bit of GetClientInfo that is actually used seems to be userEP as part of the
OSSL osGetAgentIP() script function. Now commented are the parts where
we serialize and copy out the *entire* packet queue of the client
(locking the packet handler in the process).
- uses Environment.TickCount for all timestamps (instead of more
costly Util.UnixTimeSinceEpoch()
- takes care of Environment.TickCount overflow (which will happens
after 24.8 days of system uptime)
- avoids instantiating List copies for each check
- gets rid of one lock() invocation
- moves calculation of loop invariant variable out of the loop itself
option for LLUDPServer. On windows .NET the default socket receive
buffer size is 8192 bytes, on recent linux systems it's about
111K. both value can be a bit small for an OpenSim instance serving
many clients. The socket receive buffer size can be configured via
an OpenSim.ini config option
- adds a general catch clause to LLUDPServer.OnReceivedData() to
prevent it submerging when an unexpected Exception occurs.
This change moves texture send processing out of the main
packet processing loop and moves it to a timer based
processing cycle.
Texture packets are sent to the client consistently over
time. The timer is discontinued whenever there are no
textures to transmit.
The behavior of the texture sending mechanism is controlled
by three variables in the LLCLient section of the config
file:
[1] TextureRequestRate (mS) determines how many times per second
texture send processing will occur. The default is 100mS.
[2] TextureSendLimit determines how many different textures
will be considered on each cycle. Textures are selected
by priority. The old mechanism specified a value of 10 for
this parameter and this is the default
[3] TextureDataLimit determines how many packets will be sent for
each of the selected textures. The old mechanism specified a
value of 5, so this is the default.
So the net effect is that TextureSendLimit*TextureDataLimit
packets will be sent every TextureRequestRate mS.
Once we have gotten a reasonable feeling for how these parameters
affect overall processing, it would be nice to autonmically manage
these values using information about the current status of the
region and network.
Note that this also resolves the pathologcal problem that
previously existed which was that a seated avatar generated very
few in-bound packets (theoretically) and would therefore be the
least able to retrieve the images being displayed by a
projector script.
We've encountered problems with textures never fully downloading and
objects not moving or being deleted (from the client's point of view)
even when the bandwidth settings on the client have been set very
low. This can happen over reasonably lossy links (eg you're on the
other side of the world from the server) as the server retries 3 times
and then gives up.
Whilst its possible to set ReliableIsImportant, this forces the server
to keep retrying no matter what which potentially could lead to
problems. This patch allows for the setting of MaxReliableResends
explicitly (is set to 3 normally) in OpenSim.ini so if you know you
will have clients connecting with poor connections you can set it a
bit higher (10-15 works quite well even for very poor connections).
This may break a lot of things, but it needs to go in. It was tested in standalone and the UCI grid, but it needs a lot more testing.
Known problems:
* HG asset transfers are borked for now
* missing texture is missing
* 3 unit tests commented out for now
* User interface is ... primitive at best right now.
* Loads bans from bans.txt and region ban DB on startup, bans.txt is in the format of one per line. The following explains how they are read;
DNS bans are in the form "somewhere.com" will block ANY matching domain (including "betasomewhere.com", "beta.somewhere.com", "somewhere.com.beta") - make sure to be reasonably specific in DNS bans.
IP address bans match on first characters, so, "127.0.0.1" will ban only that address, "127.0.1" will ban "127.0.10.0" but "127.0.1." will ban only the "127.0.1.*" network
Don't allow packets to be resent before they have actually been sent for the
first time. Switch from serializing a packet to get it's length to the LibOMV
provided Length property. Fix resend timing. Fix the use of dangling references
to Acked packets. Fix the packet handler to play nice with the packet pool.
Fix the packet pool. Add data block recycling to the packet pool. Packet pool
is now ENABLED by default. Add config option to disable packet and data block
reuse. Add ObjectUpdate and ImprovedTerseObjectUpdate to the packets being
recycled.
to recycley data blocs within a packet. Recycle the ObjectUpdate* data
blocks. Speeds up loading even more.
This may mean that the packet pool is now viable.
Following feedback from 0003440, i've made some changes to the new texture pipeline to optimise
performance. The changes are:
- Fixed a math issue where a small percentage of images with a certain size (on the packet boundary) would not have their final data delivered. This issue has been present since pre- 0003440
- It was suggested that a discardlevel of -1 and a prioriy of 0 meant to abandon the transfer, this is incorrect and caused some textures to clog.
- The texture throttle blocking queue is now only filled in relation to the actual throttle amount.. i.e, on a connection throttled to 300k, only twenty packets will be placed in the queue at a time, on a larger connection it will be much more. This is to balance responsiveness to requests and speed, and to minimise wasted packets.
- The engine now keeps track of the number of pending textures, and the stack will not be walked if there's no textures pending, saving CPU. Textures are only considered "pending" when they've already been decoded.
- As part of the above, some textures may receive twice as much data per cycle if the number of pending textures is below the cycle threshold, this should prevent loading from slowing down when there are fewer textures in the queue.
* WebStatsModule doesn't crash on restart. GodsModule doesn't crash when there is no Dialog Module. LLUDPServer doesn't crash when the Operation was Aborted.
* ODEPlugin does 'Almost NaN' sanity checks.
* ODEPlugin sacrifices NaN avatars to the NaN black hole to appease it and keep it from sucking the rest of the world in.
* Revamps the server side texture pipeline
* Textures should load faster, get clogged less, and be less blurry
* Minor tweak to ensure the outgoing texture throttle stays private.
* Fixes mantis 3440
Addresses Mantis #3381
The current implementation works as expected if the object has no rotation or
only rotation around the Z axis; you can spin the object left or right (around
the world Z axis).
It works a little unexpectedly if the object has a non-Z-axis rotation; in this
case the body is spun about its local Z axis, not the world Z-axis. (But SL
also behaves oddly with a spin on an arbitrarily rotated object.)
* Now, the 144 unit tests takes roughly as long time to run (16s on my laptop) that the 10 long running takes. The database tests takes forever.
* Feel free to run the unit tests as you code, and the rest before commit.
* Notes: this requires heavy testing, it may cause new issues where LL have recycled agent block data for non-security purposes. It can be disabled on Line 4421 of LLClientView.cs by changing m_checkPackets to false.
* This represents approx 1/8th of the packets being checked.
* Important: HttpServer.dll was changed to HttpServer_OpenSim.dll so that the HttpServer references do not conflict if you've copied the OpenMetaverse.Http.dll and requirements to the OpenSimulator bin folder.
This means that if you reference HttpServer.dll in any projects, you will need to change the reference to HttpServer_OpenSim.dll. It still uses the Same HttpServer namespace though.
Also truncate messages that may exceed the limit set by the packet size. The limit in OpenMetaverse is 1100 bytes including a zero byte terminator.
Fixes Mantis #3244
Added a flag (bool m_autoCreateLindenStack = true) which says if the ClientStack will be autocreated and initialised when creating regions. This helps with moving ClientStacks to Region modules.
Currently this flag is hardcoded to true, as it is only for testing at the moment, so you need to change the value in the code if you want to turn off auto creating.
Added a ApplicationRegistry to OpenSimBase.
Changed LoadRegionsPlugin so it registers itself to that application registry.
Added a event to LoadRegionsPlugin, that is triggered when it creates a new scene ,although maybe this event should actually be in opensimBase incase other plugins are creating regions (like the RemoteAdminPlugin).
- handle GetUser request for nonexistent user gracefully
- include throttle levels in ClientInfo
- code to save/restore throttles in client stack
- only update/send updates to active clients
- make animation classes serializable
* Added log4net dependency to physxplugin in prebuild.xml.
* Added missing m_log fields to classes.
* Replaced Console.WriteLine with appropriate m_log.Xxxx
* Tested that nant test target runs succesfully.
* Tested that local opensim sandbox starts up without errors.
* Added estate ban table to migration scripts of all supported databases.
* Added nhibernate mapping for EstateBans property of EstateSettings
* Refactored property accessors for EstateBan object.
* Added comments for EstateBan properties.
* Ensured that NHibernate tests pass with NUnitGUI.
* Ensured that nant test target passes.
This fixes mantis #3210. Thank you, tlaukkan!
and dropped nonths ago, because it is required to get smooth region
crossings with AO running. Without it, in some corner cases, anims will
continue to run in an unstoppable state.
NOTHING has been deleted or moved off to forge at this point. what
has happened is that OpenSim.Region.Environment.Modules has been split

These changes replace all direct references to the AssetCache with
IAssetCache. There is no change to functionality. Everything works as
before.
This is laying the groundwork for making it possible to register
alternative asset caching mechanisms without disrupting other parts of
OpenSim or their dependencies upon AssetCache functionality.
line editing, context sensitive help (press ? at any time), command line
history, a new plugin command system and new appender features thet let you
type while the console is scrolling. Seamlessly integrates the ICommander
interfaces.
OpenSim.Region.Environment into a "framework" part and a modules only
part. This first changeset refactors OpenSim.Region.Environment.Scenes,
OpenSim.Region.Environment.Interfaces, and OpenSim.Region.Interfaces
into OpenSim.Region.Framework.{Interfaces,Scenes} leaving only region
modules in OpenSim.Region.Environment.
The next step will be to move region modules up from
OpenSim.Region.Environment.Modules to OpenSim.Region.CoreModules and
then sort out which modules are really core modules and which should
move out to forge.
I've been very careful to NOT BREAK anything. i hope i've
succeeded. as this is the work of a whole week i hope i managed to
keep track with the applied patches of the last week --- could any of
you that did check in stuff have a look at whether it survived? thx!
* Increases the number of ImageDataPackets we send per PriorityQueue pop and tweak it so that the number of packets is ( (2 * decode level) + 1 ) * 2, and (((2 * (5-decode level)) + 1) * 2). The first one sends more data for low quality textures, the second one sends more data for high quality textures.
sceneB
* However, I'm not convinced that the actual process in the test completely reflects reality, and a lot of stuff had to be rigged up (which should get resolved over time)
* Adds a prototype web stats module which is disabled by default. It's functional with one report right now, however, the database structure may change, so I don't recommend enabling this to keep actual stats right now. I'll let you know when it's safe.
* Adds Prototype for ajaxy web content
* removed a warning or two.
* This facility allows you to save changes to an object that you've rezzed into a region back into their original inventory item without having to take a copy of the rezzed
object.
* This pushes an identifier for the OpenSim scene to the physics scene. This allows log messages from the physics scene to identify which OpenSim scene they relate to.
* Thanks Gerhard
* However, this is not currently activated since it's not absolutely fully tested and there's a bug lurking in there to do with the sending of the BulkInventoryUpdate packets
Adds a new method to IClientAPI to allow adding message handlers
for GenericMessages (of which "autopilot" is one). Part 2 adds a
specific autopilot handler in ScenePresence.cs.
2) Removing unused variables and functions.
3) Simplifying the navigation logic in ScenePresence.cs. The
original patch was somewhat complex because it included orientation
logic for a future enhancement of orienting the avatar to point
towards the direction being walked. Currently this isn't working,
though, so I removed the orientation code, which leaves just the
smaller and hopefully simpler-to-understand movement code.
* SceneObjectPartInventory.cs isn't a particularly good name but it's probably not got a long life
* A proper inventory interface to follow
* Parallel changes for other inventory partial classes to follow at a later date
release a direct descendant of the stable 7364, with all the features and
none of the issues.
This omits the following patch chain: r7383 r7382 r7381 r7377 r7375 r7373
r7372 r7370 r7369 r7368 r7367 r7366
the IM module and makes it into a module of it's own, which can be used by
all other modules. Removes some ugly hacks. Refer to the IM module to see
how it's used. Also fixes the persistence issue (Mantis #2598)
Contains a migration. May contain nuts.
Please back up your inventory data store. This revision changes the interface
version!! No older regions can connect to these new UGAIM, and the new regions
can't connect to the old UGAIM. Fixes a long-standing issue of permissions loss
Currently persisted on MySQL only.
* This may alleviate a little the freezing experienced by existing avatars when a new client logs in
* Race condition risks look minimal since one wouldn't expect another thread to start fiddling with that presence
* Code Cleanliness Fixes in LLClientView
* Using field instead of local variable for handlerUpdatePrimGroupRotation (if you notice any new oddities with prim group rotation after this patch, please mantis)
* Implements the SendInitiateDownload method in IClientAPI
* Uses the ITerrainModule Interface to write a terrain file to disk then uses a FileStream to read the binary file from the disk and put it in a byte array. and save to the xFer list.
* It then tells the client to download the file and the client initiates an Xfer request.
* Items will now be locally cached for only 24 hours from last access. (Rather than until restart)
* Caveat: Implementing the new caching mechanism means statistics gathering on AssetCache is no longer functional. (Justin - you might want to take a look and see if you can somehow get that back and running if you still need it)
* This means the recent memory fix should now be working correctly - so the current largest memory leak should be fixed. AssetCache still needs to be addressed however.
* This patch is highly experimental and may cause clients to not be able to connect, if this is the case, it will be rolled back in approximately 5 minutes.
* Introducing IClientCore - this will be the key replacement for IClientAPI in the long run, it has a very minimal set of methods designed to allow you to access specialist API's.
* See https://lists.berlios.de/pipermail/opensim-dev/2008-September/003049.html for the early discussion on this.
* This should (hopefully) allow TestClient and stuff built on top of it to work again
* Will probably come back later and change variable names to stop this happening again
* Really this should be 1, but I think that this would be too slow compared to a Second Life server until we improve our ability to send textures of variable quality
* This may improve one aspect of sim performance where there are many avatars. However, there are still other performance problems that are unrelated to this change
* Value may be further tuned
* Removed temporary decals since the multipler setting will stick around now
* This should probably be 1, but currently by default it is 8, to reflect what was being eon3 in OpenSim before this revision. So if the client requested a maximum throttle
of 1500 kilobits per second, we would actually send out 1500 kilobytes per second
* Adjusting this multiplier down towards 1 may improve your OpenSim experience, though in other situations it may degrade (e.g. if you're using a standalone over high bandwidth
links)
* This is currently a user setting because adjusting it down may currently reveal other OpenSim bugs.
on-/offline updates, calling cards for friends.
This adds methods in the DB layer and changes the MessagingServer, so a full
update (incl. UGAIM) is necessary to get it working. Older regions shouldn't
break, nor should older UGAIM break newer regions, but friends/presence will
only work with all concerned parts (UGAIM, source region and destination
region) at this revision (or later).
I added the DB code for MSSQL, too, but couldn't test that.
BEWARE: May contain bugs.
* This may help us detect if mysterious UDP disconnects are happening because of this.
* Shouldn't be any functional change but I would appreciate a buddy check from Teravus if he has time (as for all client stack changes)
* Whilst this does automatically get the client to rebake, on crossing a region border the 'local' assets are left behind
* There may be a cunning solution (such as squirting the assets on region crossing, or having them fetched from the original region) but
instead I'm going to opt for the easy solution of keeping them in the asset database, for now
* And hopefully rebaking all the time should no longer be necessary now
* It turns out that when the client baked the texture, the uploaded asset had the Temporary flag to true (Temporary is actually deprecated).
* It also had the StoreLocal flag set to true, which signifies that the asset should be stored locally. If it disappears we should reply to the asset request with
ImageNotInDatabasePacket
* However, last time this was enabled some clients started crashing. This may well no longer be the case and needs to be tested, but in the mean time we will store
the asset instead.
* This needs to be resolved in a better way, possibly by starting to send the ImageNotInDatabase packet again instead
* This moves authentication from the client thread (where failure was difficult to detect) to the particular thread handling that packet
* I've kept the authentication outside of the crucial clientCircuits lock (though any delay here is probably swamped by the other delays associated with login)
* Also added more to the unit test to ensure this doesn't regress
* This checks that a client circuit is established when the udp server is given a use client circuit code packet
* And checks that other circuit codes do not exist
* Not sure why things still worked in the presence of this bug - possibly the problem is compensated for later on. If you are having udp session problems this bug fix may help
(though no guarantees).
* Guys, there's an endless loop there *ON PURPOSE*. Please don't try to *fix* it. We must continue to process the UDP stream buffer on clients that disconnected nastily until it ends or the UDP server accept thread will die a horrible death.
Add rezzing time to objects. Add Object return and traffic fields to land
database. Add plumbing for auto return. Implement auto return.
Contains a migration. May contain nuts.
* Regarding an earlier change, I think it would be possible to eliminate the creation of new IPEndPoints on every end receive if we did the client circuit lookup before starting
the next receive. However, this would be a performance trade off and hence not worth trying without performance testing
* This widened what I think is an existing race condition where asynchronous recieves could potentially stomp on each other's end points (though this must occur very rarely, if at
all, in reality)
* This allows multiple user profile providers to be specified in OpenSim.ini separated by commas
* If multiple providers are specified then a request for a user profile will query each in turn until the profile is either found or all have been queried
* Unfortunately I don't believe this order can currently be specified, which if true is something that will need to be fixed.
* Thanks to smeans for the original patch.
* I believe this is reasonable since code outside the Linden client stack shouldn't be aware of the packet format being used
* I would love to have made the method protected, but the LoadBalancerPlugin is still calling it and resolving that would require more work
* This should fix a long standing issue where you often wouldn't see other people simply turn around without moving at all
* Arguably lastPhysRot (to mirror lastPhysPos) is not a good name, may change variable names later
* This may help http://opensimulator.org/mantis/view.php?id=2377 where large linksets do not always correctly delete - since a lost kill packet to the client could result in
the symptoms described
* Experimenting with the PacketPool mechanism.
* It's still disabled in the code, however there's now a flag to enable it.
* Converted to use Generic Collections vs Hashtables, also now uses a list of 'OK to pool' packets, starting with the high volume PacketAck packet.
The average-value of modify.ModifyBlock.Height in LLClientView.cs:4170
seem to be incorrect or it isn't the average? Mhhh...
So the terrain build -> Flaten Sphere is unuseable.
I have put in a patch that contains a workaround while
the main problem is not solved.
* I believe this was the cause of the remaining packet_out_of_order messages in the Linden client logs
* There were race conditions where multiple clientstacks would overwrite each other's sequence numbers
* Changing network bandwidth in the preferences will now have a much more noticeable effect - a user may want to increase this if data is being slow to download from opensim
Implementation of llModifyLand() and There is a bug on
permission-check of land-terraforming: x an y-coordinates
are interchanged on function-call ExternalChecksCanTerraformLand.
Correct: x is west, and y is north. 2) Missing check of
"Other allow to terraform-flag" (Parcel.ParcelFlags.AllowTerraform)
Introduce a resend counter on the ack queue. The header "Resent" field is
now obsolete. Implement 3 resends on reliable packets, variable.
Increase default resend timeout to 3000ms and default silence threshold
to 350ms.
old way: each region module interested in chat from client had to
- subscribe to scene.EventManager.OnNewClient
- then in its OnNewClient delegate it would subscribe to
client.OnChatFromViewer to capture chat messages coming
new way: ChatModule is the only region module that uses the "old
way" approach but is now forwarding all client chat via
scene.EventManager.OnChatFromClient
- each region module interested in chat from client now only
subscribes to scene.EventManager.OnChatFromClient
this not only simplifies code, but also allows us to substitute
ChatModule with derived classes (ConciergeModule is going to be one
example).
Also, this changeset changes ChatFromViewer to ChatFromClient as it
doesn't necessarily have to be a viewer that is a chat source.
i've taken great care to only comment out those OnNewClient delegates
that were only used for getting at the client chat --- hope it's not
breaking anything.
* Switched it on by default
* Updated OpenSim.ini.example to reflect this
* Caught a UDP Server issue that occurs when the network pipe is saturated
* Still experimental :D
* This actually probably doesn't make a huge difference. We still end up resending a massive number of packets in quite a few situations, but it's not easy to consistently
reproduce this.
* Might really need some throttling of packet send to the client on the OpenSim end.
Estate/ Manager Owner Uses the Region/Estate Menu Region TAB,
and uses "Teleport Home All Users..." (Action Button), the
action will complete but no one will be teleported and all
users still function in the region ok.
* returns FAKEEVENT instead of the connection returning a 502. It doesn't like our 502's for some reason.. so, in leau of this.. send it a fake event.
* Once again, this is still 'really early' code, so please don't blame us if you have no more threads left.
* It seems kind of silly to be building a 256x256 array just to use two 16 float blocks.. but for now the layerdata routine requires it so we'll go along with that.
* We only fill a 32x16 area of the 256x256 float array with data.
* We use patches 0,0 and 0,1 for the first and second patch to determine the direction and magnitude of the wind.
Check the client dialog box (from top menu) WORLD / REGION ESTATE
/ REGION tab. The client dialog box seems to have a hard limit of
about 32 characters per line available for displaying the region
version number. Our regions are sending a string which is greater
than the limit, causing the client to wrap the text and look ugly.
* A little wind wouldn't hurt anyone, right? This is the 'slightly breezy' setting.. hopefully you won't notice 'much' of a difference.
* It turns out the terrain patch routine is similar enough to the wind version that it can be used to hack together a breeze generator with a few mods.
* Not much configuration.. yet. You only get breeze updates in the general vicinity of your camera now to keep bandwidth usage down.. and we're not talking about 'much' movement at the moment.
* initial version... could use improvement I'm sure.
and makes it use a common set of types in both engine. Fixes the issues with
running both engines and HTTP requests / listens / timers etc..
Also fixes a couple of minor Scene issues and a CTB by nullref.
for inventory REST calls for the time being, as firefox, curl, and
also python's urllib2 cannot authenticate using digest auth.
fix permission checking for prim inventory to be the same as for
normal edit ops.
