This sleep appears unnecessary since a sleep has already occurred in WaitForCallback() whilst waiting for the destination region to notify of teleport success.
There are no async operations between this sleep and the WaitForCallback()
If this sleep is present, then teleporting back to the source region within 5 seconds results in a disconnection.
If this sleep is commented out then teleporting quickly back and forth between two simulators appears to work without issue.
Tested on standalone, local grid and distributed grid.
Please revert if there's something that I've missed.
This adds a non-advertised wait_for_callback option in [EntityTransfer]. Default is always true.
Teleport tests disable the wait for callback from the destination region in order to run within a single thread.
These are identical apart from setting Velocity = zero, which has no practical effect anyway since this is zeroed when the avatar is added back to the physics scene.
This was an oversight when removing some race conditions from PhysicsActor setting recently.
Regression tests extended to probe this code path.
Extending regression tests required implementation of a BasicPhysicsPrim (there was none before). However, BasicPhysics plugin is still of no current practical use other than to fill in as a component for other parts of regression testing.
On region restart, the whole object would become physical as expected.
Observed behaviour from elsewhere is that all prims in a new linkset should take on the status of the root prim.
Add regression test for this behaviour.
prim_geom == IntPtr.Zero only before a new add prim taint is processed (which is the first taint) or in operations such as scale change which are done in taint or under lock.
Therefore, we can remove these checks which were not consistently applied anyway.
If there is a genuine problem, better to see it quickly in a NullReferenceException than hide the bug.
This involves a large amount of change in test scene setup code to allow test scenes to share shared modules
SetupScene is now an instance method that requires an instantiation of SceneHelpers, though other SceneHelpers methods are still static
May split these out into separate classes in the future.
We can now do this since the entire scene and all objects within it are now successfully gc'd at the end of these tests.
This greatly improves the time taken to run each test (by reducing teardown time, not the time to actually do the test work that we're interested in).
Slightly simplifies config read in Scene constructor to help facilitate this.
This is so that the static MainConsole.Instance doesn't retain references to methods registered by scene and other modules to service commands.
This prevents the scene from being garbage collected at the end of a test.
This is not the final thing preventing GC - next up is the timer started by SimStatsReporter that holds a reference to Scene that prevents end of test gc.
