The attached patch adds the automatic granting of PERMISSION_CONTROL_CAMERA
on request to a script when an avatar is sitting on the object that the script
resides in.
It also automatically removes PERMISSION_TAKE_CONTROLS and PERMISSION_CONTROL_CAMERA
from the scripts when an avatar stands up. It doesn't remove the other automatically
granted permissions but this follows LL server behavior. Removing these two
permissions avoids some potential race conditions (accidentally taking
control after the avatar has stood up) which may be why LL put
them in the first place.
On a call of llVolumeDetect(1) (or any other number !=0) volume
detection is enabled. Together with VD, the phantom flag is set to the GUI.
On a call of llVolumeDetect(0), vd detection is switched of again,
also the phantom state is removed. On a call to llSetState(STATE_PHANTOM,
false) while VD is active, also VD is switched off. The same is true for
unchecking the phantom flag via GUI. This allows to take back VD without
the need to script just by removing the phantom flag.
Things missing in this patch: persistance of the volume-detection flag.
This needs more discussion and will be included in another patch soon.
It is not documented to be applied to llGetTimeOfDay at all and is not appropriate for the other two because dilation does not directly affect script speed in OS.
Fixes Mantis #2783 and #2162
The attached patch ads an OpenSim.ini option (AutomaticLinkPermission)
which when enabled makes PERMISSION_CHANGE_LINKS to be granted to
scripts by default. When enabled llGetPermissions will always return it
as granted and llCreateLink//llBreakLink will succeed without
doing llRequestPermissions. ONLY ENABLE THIS IN TRUSTED ENVIRONMENTS.
The patch also fixes a minor bug in llCreateLink
related to a potential dereference of a null client object.
* Warning! Physics API change. This means that the NBodySimulation needs to be updated!
* PhysicsActor -> void SetVolumeDetect(int) needs to go into classes that use PhysicsActor as their base class.
The attached patch fixes the bug where llCreateLink will cause a null dereference
if the avatar who gave link permission for the object is no longer logged in.
Use height calculation in Basic Physics and Physics of Simplicity so that avatars larger than the default walk with straight legs and shorter walk on the ground.
* Entities should now in theory be lock-free externally.
* Other properties may cause blocking however[?].
* ScenePresence maintains separate locks so isn't fixed by this commit.
* 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
* This renders RootPart == null checks useless - the replacement is to check SOG.IsDeleted. However, in many cases this will not be necessary since updates to deleted parts
will not be sent to the client
* This should remove any remaining race conditions where an object is deleted while another thread is yet to obtain the root part to perform some operation
* Doing this is probably a necessary prerequisite to moving to a model without a separate SOG and SOP
* Unfortunately it's not possible to eliminate all RootPart == null checks since in some contexts it is currently used to check whether an object was created successfully
causes defautlt behavior. "true" now means usable unconditionally, "false"
means disabled, and a list of UUIDs restricts it.
This changes SECURITY! If you used "true" here before, you shoudl review
your setup!
