The functionality is the same but this allow us to monitor such tasks via "show threads" and abort them for test purposes, etc.
Also extends thread names to provide more info (e.g. SendInitialDataToClient says what client the task is for).
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.
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.
Relates to mantis 7276
Previously we used a heuristic of checking if the entry position is 0 to differentiate between Teleport and Cross, but that doesn't work anymore since we've started providing the precise entry position for cross, too. That's required in order to ensure that the user is allowed to enter the parcel that he's walking into.
This includes additions to Warp3D:
Optional rendering of mesh and scupltie prims (INI parameter. Off by default)
Texturing of large prims (INI parameter. On by default)
Better garbage collection
Rename 'RegionWorldLocX' to 'WorldLocX' and same for Y and Z.
This keeps the downward compatibility and follows the scheme of 'region'
and 'world' location naming that is happening in the Util module.
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.
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 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.
This is for testing and debugging purposes to help determine whether a particular issue may be teleport related or not
"SIMULATION/0.2" (the newer teleport protocol) remains the default. If the source simulator only implements "SIMULATION/0.1" this will correctly allow fallback to the older protocol.
Specifying "SIMULATION/0.1" will force the older, less efficient protocol to always be used.
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...
