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.
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.
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
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.
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.
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
This may have been the trigger CheckSendingPatchesToClients() dictionary out of sync exceptions in today's load test.
Don't need to check ContainsKey() since Remove() returns false on a request to remove a key that it doesn't have
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.
This governs when child agent position changes are sent to neighbouring regions.
Corresponding config parameter is ChildReprioritizationDistance in [InterestManagement] in OpenSim.ini
For test purposes.

It can't be done this way because the stats data needs to show up on the console at all log levels, not just debug.
But this means setting it to log at fatal, which is not appropriate for this stuff in the log.
I understand the desire but this has to be done some other way, perhaps by (yet another) config parameter.
Also, this was already being done with the ClientStatsReport but that also should be done in another way, I think.
This reverts commit 5d53412766.
I forgot that a null 'their version' would not be passed over the wire and ends up as an empty string instead (like older simulators).
So instead pass through the correct simulator protcol version instead (SIMULATOR/0.3) when querying from login or hg login.
Also removes a debug console write for agent limit accidentally left in for the same commit.

Another manifestation of this bug is that after a Hypergrid teleport, when you click on one of the avatar's attachments the object doesn't show its name. This means that the viewer knows the attachment is there, but the simulator does not.
The problem was caused by treating Hypergrid teleports as if they're Logins (because the teleport flag ViaLogin is enabled).

This caused the client to stop responding, and even the simulators to have problems. The solution is to disallow crossing before the previous cross has completed.
This, by default, enables terrain patches being sent to each avatar
from the avatar away (rather than the old outside-in pattern), only
sending terrain patches within the avatars view distance (making
view loading quicker), and sending multiple terrain patches per
protocol packet (making terrain loading and editing quicker).
co-op should be more stable as it doesn't abort threads, which can trigger virtual machine instability
This change will be invisible to users as script DLLs are recompiled automatically where necessary, though the change won't take affect until the next simulator restart.
This change has no effect on existing script state.
If you want to continue using abort, set ScriptStopStrategy = abort in the [XEngine] section of OpenSim.ini
As per http://msdn.microsoft.com/en-us/library/system.random%28v=vs.100%29.aspx, the .NET Random class is not thread-safe.
If called by multiple threads at once, methods may return 0.
Except for llRand(), other OpenSimulator code did not lock before calling a shared Random instance.
This commit adds a ThreadSafeRandom class that extends Random but does internal locking so that it is thread-safe.
This change is invisible to existing callers and the explicit locking in the llFrand() implementation is now redundant.
We have to do this since we can't unload existing DLLs if they're all in the same AppDomain.
But we can still update the underlying DLL which will be used in the next simulator session.
Code was identical apart from error logging, but if there are failures creating these directories then you'll be
seeing lots of errors anyway, and these will be more informative
I think it's still useful to know this to show up any errors early, but it's reasonable to still carry on rather than throw an exception.
Follow on from Diva's commit 9643792
If the C# column can't be found in the positionMap (but the line can),
use the map immediately after it while correcting for the offset,
unless that results in an LSL position before the previous LSL position
in the positionMap.
The idea behind this heuristic is that in most, if not all cases C#
consumes more characters than LSL (for example LSL_Types.LSLInteger
instead of just 'integer').
Thus if the distance between the columns of two markers differ in
the C# and LSL file, the distance in the C# file will be larger.
Moreover, we can assume that every time this happens we will have
a marker at the beginning of the longer 'keyword', because those
keywords were generated by us in the first place.
For example:
C#: LSL_Types.LSLInteger f2(LSL_Types.LSLString s)
^ ^
1 2
will always have markers at the beginning of the long keywords
'LSL_Types.LSLInteger' and 'LSL_Types.LSLString'.
If an error is generated in between (for example at the beginning
of the function name 'f2') then the correct position is found
by using an offset relative to 2 rather than 1.
Note that a case where this isn't working correctly is
when the user adds extra spaces. For example:
LSL: integer f2( string s)
would still use the start of 'string' as reference and
then go backwards 3 characters only because the corresponding
C# still looks like
C#: LSL_Types.LSLInteger f2(LSL_Types.LSLString s)
^ ^
only 3 chars difference
and the reported error at 'f2' would be here:
LSL: integer f2( string s)
^
This can only be fixed by generating a mapping for 'f2' itself, or
generating a mapping whenever the amount of spaces is changed.
When a compile error reports a colum/error that is not an exact
match in the positionMap dictionary, the last position in the
map with a line number and position before the reported error
should be returned.
The old code had the following problems:
1) It returns l,c - which are line and column of the C# file, not LSL.
2) It doesn't set l to 'line' when the map has an entry with 'line'.
3) It sorts the map without taking columns into account, which may
result in a random order of the columns. With my mono implementation
the columns were reversed in order.
For example, if the map contains the following lines:
99,5,49,10
100,30,50,10
100,40,1,0
101,5,51,10
and a translation of 100,35 was requested,
then the old code would compare '100' with the keys in
the first column - setting l to that key while it is
smaller. Hence, l is set to 99.
Then it finds the key 100 and doesn't update l.
Because of the reversed sort order, it first compares
the column 35 with 40, finding that it is smaller
and therefore it stops; returning 99,1 instead of finding
the correct 100,30 entry and returning 50,10.
This patch causes 50,10 to be returned.
The remaining problems after this patch are:
1) The sorting might not be necessary at all.
2) The is code duplication (I fixed both instances,
but really there should be no code duplication
imho).
AvatarFlyingGroundMargin and AvatarFlyingGroundUpForce set to 5.0 and
2.0 respectively which seems to give about the same action as in SL.
Also moved force addition to before the velocity to force computation
so the upward velocity is properly applied to the avatar mass.
This is because jump statement generation was mistakenly inserting its own line without updating the csharp positions in CSCodeGenerator.
This is Aleric Inglewood's patch in http://opensimulator.org/mantis/view.php?id=7195 but applied to opensim itself rather than the defunct code generation in opensim-libs. Thanks!
This patch also adds a regression test for this case from myself.
