Routines in Util to compute region world coordinates from region coordinates
as well as the conversion to and from region handles. These routines have
replaced a lot of math scattered throughout the simulator.
Should be no functional changes.
* Add an IsBlocked(string Key) method so it can be used more generically. (think.. if we want to rate limit login failures, we could have a call in the Login Service to IsBlocked(uuid.ToString()) and ignore the connection if it returns true, if IsBlocked returns false, we could run the login information and if the login fails we could run the Process method to count the login failures.
* Applied the XmlRpcBasicDOSProtector.cs to the login service as both an example, and good practice.
* Applied the BaseStreamHandlerBasicDOSProtector.cs to the friends service as an example of the DOS Protector on StreamHandlers
* Added CircularBuffer, used for CPU and Memory friendly rate monitoring.
* DosProtector has 2 states, 1. Just Check for blocked users and check general velocity, 2. Track velocity per user, It only jumps to 2 if it's getting a lot of requests, and state 1 is about as resource friendly as if it wasn't even there.
-- addition of varaible region size in X and Y
-- internal storage of heightmap changed from double[] to short[]
-- helper routines for handling internal structure while keeping existing API
-- to and from XML that adds region size information (for downward compatibility,
output in the legacy XML format if X and Y are 256)
Updated and commented Constants.RegionSize but didn't change the name for compatibility.
count number to integer world coordinates.
Added new methods RegionWorldLoc[XY].
Refactored name of 'RegionLoc*' to 'LegacyRegionLoc*' throughout OpenSim.
Kept old 'RegionLoc*' entrypoint to RegionInfo for downward compatability
of external region management packages.
This makes scripted object sounds and a few other things play by default instead of having to switch the viewer to adult
This reduces the support burden
This is not guaranteed to be accurate since users may be left "online" in certain situations.
For example, if a simulator crashes and they never login/logout again.
To counter this somewhat, only users continuously online for less than 5 days are shown.
This requires a new GridService.GetDefaultHypergridRegions() so ROBUST services require updating but not simulators.
This method still returns regions flagged with just DefaultRegion after any DefaultHGRegions, so if no DefaultHGRegions are specified
then existing configured defaults will still work.
Immediate use is for conference where we need to be able to specify different defaults
However, this is also generally useful to send experienced HG users to one default location and local users whose specified region fails (e.g. no "home" or "last") to another.
Disabled by default. Enable by setting
[Startup]ManagedStatsRemoteFetchURI="Something"
and thereafter "http://ServerHTTPPort/Something/" will return all the managed
stats (equivilent to "show stats all" console command).
Accepts queries "cat=", "cont=" and "stat=" to specify statistic category,
container and statistic names. The special name "all" is the default and returns
all values in that group.
This can currently only be activated with the console command "debug stats record start".
Off by default.
Records to file OpenSimStats.log for simulator and RobustStats.log for ROBUST
This reflects the actual use of this stat - it hasn't recorded general exceptions for some time.
Make the sim extra stats collector draw the data from the stats manager rather than maintaing this data itself.
The major departure from flotsam is to send only one message per destination region, as opposed to one message per group member. This reduces messaging considerably in large groups that have clusters of members in certain regions.
In this new protocol, and as committed before, the viewer is not sent EnableSimulator/EstablishChildCommunication for the destination. Instead, it is sent TeleportFinish directly. TeleportFinish, in turn, makes the viewer send a UserCircuitCode packet followed by CompleteMovementIntoRegion packet. These 2 packets tend to occur one after the other almost immediately to the point that when CMIR arrives the client is not even connected yet and that packet is ignored (there might have been some race conditions here before); then the viewer sends CMIR again within 5-8 secs. But the delay between them may be higher in busier regions, which may lead to race conditions.
This commit improves the process so there are are no race conditions at the destination. CompleteMovement (triggered by the viewer) waits until Update has been sent from the origin. Update, in turn, waits until there is a *root* scene presence -- so making sure CompleteMovement has run MakeRoot. In other words, there are two threadlets at the destination, one from the viewer and one from the origin region, waiting for each other to do the right thing. That makes it safe to close the agent at the origin upon return of the Update call without having to wait for callback, because we are absolutely sure that the viewer knows it is in th new region.
Note also that in the V1 protocol, the destination was getting UseCircuitCode from the viewer twice -- once on EstablishAgentCommunication and then again on TeleportFinish. The second UCC was being ignored, but it shows how we were not following the expected steps...
- The existing event to scene has been split into 2: OnAgentUpdate and OnAgentCameraUpdate, to better reflect the two types of updates that the viewer sends. We can run one without the other, which is what happens when the avie is still but the user is camming around
- Added thresholds (as opposed to equality) to determine whether the update is significant or not. I thin these thresholds are ok, but we can play with them later
- Ignore updates of HeadRotation, which were problematic and aren't being used up stream
successfully tested, and I'm merging back those changes, which proved to
be good.
Revert "Revert "Cleared up much confusion in PollServiceRequestManager. Here's the history:""
This reverts commit fa2370b32e.
When Melanie added the web fetch inventory throttle to core, she made the long poll requests (EQs) effectively be handled on an active loop. All those requests, if they existed, were being constantly dequeued, checked for events (which most often they didn't have), and requeued again. This was an active loop thread on a 100ms cycle!
This fixes the issue. Now the inventory requests, if they aren't ready to be served, are placed directly back in the queue, but the long poll requests aren't placed there until there are events ready to be sent or timeout has been reached.
This puts the LongPollServiceWatcherThread back to 1sec cycle, as it was before.
This reverts commit 21a09ad3ad.
After more analysis and discussion, it is apparant that the Count(), Contains() and GetQueueArray() cannot be made thread-safe anyway without external locking
And this change appears to have a positive impact on performance.
I still believe that Monitor.Exit() will not release any thread for Monitor.Wait(), as per http://msdn.microsoft.com/en-gb/library/vstudio/system.threading.monitor.exit%28v=vs.100%29.aspx
so this should in theory make no difference, though mono implementation issues could possibly be coming into play.
This reverts commit 42e2a0d66e
Reverting because unfortunately this introduces race conditions because Contains(), Count() and GetQueueArray() may now end up returning the wrong result if another thread performs a simultaneous update on m_queue.
Code such as PollServiceRequestManager.Stop() relies on the count being correct otherwise a request may be lost.
Also, though some of the internal queue methods do not affect state, they are not thread-safe and could return the wrong result generating the same problem
lock() generates Monitor.Enter() and Monitor.Exit() under the covers. Monitor.Exit() does not cause Monitor.Wait() to exist, only Pulse() and PulseAll() will do this
Reverted with agreement.
This adds explicit cap poll handler supporting to the Caps classes rather than relying on callers to do the complicated coding.
Other refactoring was required to get logic into the right places to support this.

This was a regression since commit 831e4c3 (Thu Apr 4 00:36:15 2013)
This commit also adds a regression test for this case, though this currently only works with Mono
This aims to address http://opensimulator.org/mantis/view.php?id=6704
This currently prints caps requests received and handled, so that overload of received compared to handled or deadlock can be detected.
This involves making BaseStreamHandler and BaseOutputStream record the ints, which means inheritors should subclass ProcessRequest() instead of Handle()
However, existing inheriting classes overriding Handle() will still work, albeit without stats recording.
"show caps" becomes "show caps list" to disambiguate between show caps commands
This is in order to reduce the likelihood of naming clashes, make it easier to filter in/out attributes, ensure uniformity, etc.
All dynattrs in the opensim distro itself or likely future ones should be in the "OpenSim" namespace.
This does alter the underlying dynattrs data structure. All data in previous structures may not be available, though old structures should not cause errors.
This is done without notice since this feature has been explicitly labelled as experimental, subject to change and has not been in a release.
However, existing materials data is being preserved by moving it to the "Materials" store in the "OpenSim" namespace.
e.g. "show stats server.network"
I failed to realize this had already been implemented without the period in the show stats command (as the command help had not been updated).
However, I would prefer the . approach as it will allow specifying multiple stats, easier wildcarding, etc.
This commit also prevents any stat from having a period in its short name.
This was the original intention with these stats, as I didn't believe they would be useful to ordinary users if everything is working as it should.
Please amend if this is an issue.
Just for now, levels actually have no impact on what is displayed via the "show stats" command.
hashes for the purpose of accurately responding to AgentTextureCached
packets. There is a change to IClientAPI to report the wearbles hashes
that come in through the SetAppearance packet. Added storage of the
texture hashes in the appearance. While these are added to the
Pack/Unpack (with support for missing values) routines (which means
Simian will store them properly), they are not currently persisted in

packet can be pulled out of LLClientView and moved to
AvatarFactory. The first pass at reusing textures (turned off by
default) is included. When reusing textures, if the baked textures
from a previous login are still in the asset service (which generally
means that they are in the simulator's cache) then the avatar will not
need to rebake. This is both a performance improvement (specifically
that an avatars baked textures do not need to be sent to other users
who have the old textures cached) and a resource improvement (don't
have to deal with duplicate bakes in the asset service cache).
