there is only one element in the range, it must
also coincide with the specified stride. The
existing code assumes that the stride starts at
start ( which is the expected and most useful
behavior).

Linux (as an example), it is possible for the existence check to fail
because the file is not yet recognized by the file system. Although
the loop has a 250mS delay, in practise, the existence test in the for
loop is successful and no delay is introduced.
Next, this takes care of the two, unpredictable, situations where a
script fails to compile. The first is caused by an occasional SEGV in
the underlying mono VM while mcs is running, the second is caused by
file system latency.

Applied with changes:
llGetSimulatorHostname was not changed, because the change breaks
existing behavior and carries a data exposure risk. That value needs
to be configurable, the proposed fixed change is not acceptable.
This patch allows the land owner to dynamically set the SIP address of a particular land parcel from script. This allows predetermined SIP addresses to be used, making it easier to allow non OpenSim users to join a regions voice channel.

the message is directed to the OpenSim console log (and NOT
forwarded to the client). This is a great way to capture scripting
events to the log. To enable, add ScriptConsoleChannel = -xxx to
the ScriptEngine parameters in the .ini file. Note that the
message is written using Console.WriteLine rather than
the rather more fragile log4net service. The console channel is
also not subjected to the 1024 character limit imposed on regular

* LongVersion nIni may be causing the test thread death. Pausing OpenSimulator during startup causes a nIni error that makes debugging startup operations difficult for users. It might be because when it's in pause mode, something else reads from the nini config passed? If it is, it might not be fixable.. however, if it's concurrency that causes nini death it would make sense to give each section of the tests a new IConfigSource so that they don't read from the same configsource at the same time.
This needs to be looked into. This commit, unfortunately, reinstates
a memory leak in regions that see significant script fluctuation,
e.g. lots of scripted attachments, or script development.
Fixes Mantis #3979
Applied with changes. Changed ThreatLevel to High since all discovery

|Subject: [PATCH] Closed two major memory leaks for scripted objects
|
|Two major memory leaks for the scripted objects were fixed
|- One leak had to do with remoting acrossing app domains. When a script and
| its controlling agent communicate across an application boundary, it calls
| functions on a stub proxy object that then invokes the remote method on
| the object in the other app domain. These stub objects (two for each script)
| were setup to have infinate lifetimes and were never being garbage collected.
|- The second leak was the result of adding a scene object part instance method
| to a scene event and never removing it. This cause the event's delegate list
| to maintain a link to that object which is then never freed as the scene event
| object is never destroyed.
Patch applied, please direct feedback to me. Possible issue: Longtime idle
scripts like vendors may fail.
[1] Added a new OnAttach event to Scene/EventManager
[2] Hooked up existing attach event handler in XEngine.
[3] Modified SceneGraph and Scene.Inventory to trigger
attach events at the appropriate places. I was forced
to distribut the changes across two files because of
the way attach processing is distributed across the
two files.
[4] In the case of RezSingleAttachmentFromInventory it is
necessary to handle event scheduling in a special way.
There is no synchronous path available, so the fact
that this object is attached, and who it is attached to,
is cached when the ScriptInstance is created. When
the script is started, the attached handler is driven
after on_rez (but before changed, this should be reviewed).

The vector parameter to llSetPos() specifies an absolute position for
an unlinked prim or the root prim of a linkset; however, when the
function is used by a child prim, the vector specifies a relative
offset from the root prim. The changed introduced in llSetPos() treats
this value as an absolute position in all cases, which has the unintended
effect of mangling the position of child prims.
balancer plugin work again. Create a new method, GetClientEP, to retrieve
only the EndPoint for script usage. Marked the purpose of the method
in IClientAPI.cs with a warning. Also restored the corresponding SetClientInfo
functionality.
Attached is a patch that changes the oar file saving of creation date/time to an integer
instead of a string. I did this after justincc emailed me saying there is a problem
with internationalisation doing it the old way and I said I'd fix it. Its been
tested with MySQL and I've made the changes for MSSQL but that hasn't been well tested.
Changing the names of these methods because they were being picked up by
nunit as tests even though they were marked private. Naming them Check*
after the original Test*.
This change addresses two issues:
[1] It adds a flag field to the blendface call which allows the
caller to indicate whether or not the generated asset is
temporary, and whether or not the asset being replaced should
be explicitly retired fromt the memory cache. The decimal
values correspond to:
0 - Permanent asset, do not expire old asset
1 - Permanent asset, expire old asset
2 - Temporary asset, do not expire old asset
3 - Temporary asset, expire old asset
'3' corresponds to the default behavior seen today, and is
the continued behavior of the non-blendface calls.
[2] The dynamic texture routines are highly-asynchronous and can
be scheduled simultaneously on a multi-core machine. The nature
of the texture management interfaece is such that updates may
be lost, and the nature of asynchornous operation means that
they may be processed out of order. A lock has been added to
ensure that updates are at least atomic. No attempt has been
made to enforce ordering. The lock applies to the SceneObjectPart
being updated and is held for the lifetime of the TextureEntry
used to carry texture updates (the one instance carries all
faces supported by the prim).
Users of these services should remember that the dynamic texture
call is asynchronous and control will be returned *before* the
texture update has actually occurred. As a result, a isubsequent
GetTexture call may not return the expected asset id. A script
must wait for the corresponding TEXTURE_CHANGED event before
retrieving any texture information.
SL's LSL supports lone idents:
integer x;
x;
as well as lone idents in for-loop assignments:
for (x; x < 10; x++) { ... }
while those are errors in C# (MONO at least). This patch skips lone
idents in such places.
Fixes Mantis #3042.
For loops with no assignment are no longer syntax errors. For example,
this is now valid:
for ( ; i < 10; i++) { ... }
Corresponding changes to lsl.{lexer,parser} in r99 in opensim-libs.
Fixes Mantis #2501. Fixes Mantis #2884.
It seems overloading the method TestllAngleBetween confused nunit a bit
and caused it to try running the private TestllAngleBetween method. The
method's access modified prevented that from happening, and nunit
complained.
This patch adds oar file date and time (UTC) meta data to an oar file
when it is created. It also adds a unique ID, though this id does not
in anyway identify the machine that the oar file was created on.
When an oar file with this meta data is loaded this extra information
is saved with the region settings and available via LSL through:
- osLoadedCreationDate()
- osLoadedCreationTime()
- osLoadedCreationID()
If there is no meta data these fields will be blank. Subsequent oar
file loads will erase the information for the previous oar file
load. Persistence has only been implemented for MySQL, the other
backends need updating.
Overall this allows us to much more easily identify the specific version of
software that clients are using. Its very straightforward to edit the oar file
to change the ID string to be something more human friendly.
Included in the patch is a new file OpenSim/Data/MySQL/Resources/030_RegionStore.sql
required for the MySQL DB migration.
btw I had a chat with justincc about this a few weeks ago since he
wrote the oar file import/export and he sounded happy to accept
something that included date/time information but didn't want anything
that would silently leak private information like machine names.
The attached patch implements llPassTouches. It has been added
to the export/import XML along with the flag for AllowedInventoryDrop.
The MySQL backend has been updated as well, though I haven't
done one of those before so could do with a check. I added
the migration mysql file as well.
The other data backends need updating as well.

Changes to support client-side image pre-caching in the region. This
commit adds an additional calling sequence to the DynamicTexture data

This is in part fulfilment of ticket #458.
This may break a lot of things, but it needs to go in. It was tested in standalone and the UCI grid, but it needs a lot more testing.

This is to handle the changes in the v1.23 viewer
of LL regarding the adult rating. With this patch
a region can be changed to the adult rating from
LL viewer v1.23 and above.
- AssetType isn't InventoryType. Those enums contain different numbers. Use AssetType for the asset type, InventoryType for the inventory type.
- The ToString method (or ToLower) of AssetType/InventoryType doesn't necessarily return the correct LLSD string.
- Replaced several magic numbers by their corresponding enum.
- Fixed the invType for gestures and animations in the library.
This should fix Mantis #3610 and the non-terminating inventory loading
that region. I decided against sending the terrain on every call to osTerrainSetHeight
(which makes it abysmally slow), and added a osTerrainFlush instead, which should be
called after all the terrain-changes have been done. Changed some return types to
LSL types, too, and removed some end-of-line spaces.
This is sent to all root prims of all attachments of an avatar when the
animation state changes. llGetAnimation() can thenbe used to find the
new movement animation. This eliminates the need for fast timers in AOs
of objects from the scene, and of scripts from objects. This facilitates
the development of modules that can register prims with externall servers
for inbound email and XMLRPC. Currently implemented in XEngine only.

With some support from HomerH, this patch adds support for Wind
Model plugins via the mono.Addin framework.
* Adds console & OSSL access to Wind Parameters
* Adds plug-in support for custom wind models
* Provides two example Wind Model plug-ins
Documentation for the wind module is temporarily located at http://code.google.com/p/flotsam/wiki/CoreWindModule [^]
-- will move this documentation to http://opensimulator.org [^]
after the patch has been committed.
* Important: HttpServer.dll was changed to HttpServer_OpenSim.dll so that the HttpServer references do not conflict if you've copied the OpenMetaverse.Http.dll and requirements to the OpenSimulator bin folder.
This means that if you reference HttpServer.dll in any projects, you will need to change the reference to HttpServer_OpenSim.dll. It still uses the Same HttpServer namespace though.
number map. Instead, write the map to a file for later use. That is not

Attached is a patch which enabled through an OpenSim.ini option the ability
to read long notecard lines. Currently although the data is read from
the notecard it is truncated at 255 characters (same as for the LL servers.
This patch allows the setting of that limit to a different value.
; Maximum length of notecard line read
; Increasing this to large values potentially opens
; up the system to malicious scripters
; NotecardLineReadCharsMax = 255
this allows for save/restore functionality using notecards without
having to worry about very short line length limits.
Attached is a patch which provides osAvatarPlayAnimation() the ability to
also trigger animations contained within the same prim as the script, as
llStartAnimation() does. (It also modifies osAvatarStopAnimation(),
otherwise the script wouldn't be able to stop animations it had started.)
* In most cases, the setting in OpenSim.ini.example is taken as the canonical one since this is the file virtually everyone ends up using
* OpenSim will start up with a blank OpenSim.ini, in which case sqlite is the default database (as before)
It's good practice to isolate unit tests so their outcome (pass/fail)
does not depend on whether another test has been run/passed/failed. A
method is used to populate the DB independently for each test, and a
TearDown method cleans up the database after each test.
Also adding extra comment in C-style comment test.
Also truncate messages that may exceed the limit set by the packet size. The limit in OpenMetaverse is 1100 bytes including a zero byte terminator.

llSetHoverHeight() should not clamp the x/y position of an object the way MoveTo does,
and it should recalculate the absolute height to hover at as an object moves to reflect
the current ground/water height under it.
Correctly implementing required adjusting the Physics interfaces and implementing at
the physics plug-in level. The attached is a patch that correctly implements
llSetHoverHeight() including updates to the ODE physics plug-in.
Changes to IWindModule interface: Change from assuming a single array of
256 Vector2 values to a lookup function that takes region x, y, z and returns a Vector3
* Changed llWind() to use new lookup method of IWindModule
* Moved logic for determining the wind at a given point in the data array from
llWind() to the Wind Module itself.
isn't tested, but it doesn't break anything else. The reason for this
function is to let in world tools be used to coordiante out of world
network services that need access to client ip addresses.
* Added log4net dependency to physxplugin in prebuild.xml.
* Added missing m_log fields to classes.
* Replaced Console.WriteLine with appropriate m_log.Xxxx
* Tested that nant test target runs succesfully.
* Tested that local opensim sandbox starts up without errors.
The built-in default is OpenSim, unless a user server url is given, then
that is used, unless "shard" is also goven, then shard takes precedence.
The defult in OpenSim.ini is "OpenSim" for compatibility.
* Not locking causes enumeration exceptions as described in this matis
* part.TaskInventory needs to be locked for every access as it's a dictionary
* Extra locking will hopefully not cause any major issues - in places where the enumeration of the dictionary performs other lock or long running operations, the dictionary is
cloned instead
The attached patch implements osGetDrawStringSize that looks like:
vector osGetDrawStringSize(string contentType, string text, string
fontName, int fontSize)
in LSL. It is meant to be used in conjunction with the osDraw*
functions. It returns accurate information on the size that a given
string will be rendered given the specified font and font size.
This allows for nicely formatted and positioned text on the generated
image.
and dropped nonths ago, because it is required to get smooth region
crossings with AO running. Without it, in some corner cases, anims will
continue to run in an unstoppable state.
The following patch fixes http://opensimulator.org/mantis/view.php?id=3107

child prim being rotated relative to root prim in linked set.
In SL if llAbs() is called with the minimum integer value of -2147483648
it will return that value untouched without error.

move out to forge.
I've been very careful to NOT BREAK anything. i hope i've
succeeded. as this is the work of a whole week i hope i managed to
keep track with the applied patches of the last week --- could any of
you that did check in stuff have a look at whether it survived? thx!
This changeset fixes a race condition where a script (XEngine run) can
startup before a reference is added to it in all of the required
places in the XEngine class. The effect of this is that a script can
sometimes on startup miss script events. For example a script which
starts up and initialises itself from a notecard may never receive the
dataserver event containing the notecard information.
The patch isn't as clean as I'd like - I've split the constructor of
ScriptInstance up so it does everything it did before except
call Startup and post events like state_entry and on_rez. An Init
function has been added which is called after the ScriptInstance
object has been added to the necessary data structures in XEngine.
Happy to rework it if someone suggests a better way of doing it.
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!
the IM module and makes it into a module of it's own, which can be used by
all other modules. Removes some ugly hacks. Refer to the IM module to see
how it's used. Also fixes the persistence issue (Mantis #2598)
* This doesn't allow complete script lockdown of a sim, many avenues (copying, editing) are still uncloseable at the moment
* Default remains to allow all users to create scripts (subject to existing permissions if enabled)
This patch makes llAllowInventoryDrop work with the permissions module
enabled. Changes include:
- Enabled PropagatePermissions when permissions module serverside perms
is on
- change ownership of item when item is dropped into an object.
Ownership changes to the owner of the object the item is dropped into
- propagation of permissions if the permissions module enabled (eg
next-owner mask applied)
- CHANGED_ALLOWED_DROP is now passed to the change script event if an
item was allowed to be dropped into the object only because
llAllowInventoryDrop is enabled (instead of CHANGED_INVENTORY being
passed).
- Sets object flags correctly when llAllowInventoryDrop is called so
clients are notified immediately of the change in state. Am not
sure that calling aggregateScriptEvents is the right way to do it,
but it works and seems to be the only way without making further
changes to update LocalFlags
PRIM_TEMP_ON_REZ and PRIM_MATERIAL are not implemented in
llSetPrimitiveParams so support for these is in the patch.
Also two deprecated functions throw errors. They are changed
to behave as in SL: llSetPrimURL - Does nothing except the sleep
(currently commented out) & llRefreshPrimURL shouts
"llRefreshPrimURL - not yet supported" on the error channel
potential (asset bloat, asset server DOS due to no enforced delay)
Formatting cleanup. Change default permissions on the notecard to
not include "anyone can copy" and "anyone can move", as they are
meaningless on non-prim items.
* Inserts proper animation state names into data/avataranimations.xml file so that llGetAnimation() works as one would expect.
* Thanks StrawberryFride!
* This is a partial implementation of llGetAnimation that returns the name of the animation as stored in data/avataranimations.xml but not its state name (since we don't yet
have these).
* Thanks StrawberryFride
This patch allows an object to directly message another object given its
key using the method osMessageObject(key objectUUID,string message).
to communicate with an object it must implement the dataserver listener
method. The dataserver method is passed the key of the calling object
and a string message.
* The attached patch changes the LSLInteger operator overrides for == and != to return LSLIntegers 1 or 0 instead of a bool and adds similar operator overrides for >, <, >= and
<=
* Thanks idb!
