* These have been mostly replaced by the PriorityQueue sender in LLClientView (it was still using threads and poll processing!)
* Thread Reduction!
* Might have been sending more image packets then necessary previously, texture times 2. We'll see if this reduces the texture packet load.
* If this doesn't melt the Http Server, this will significantly reduce the number of threads in use on regions with many users.
* Adds AddPollServiceHTTPHandler, and RemovePollServiceHTTPHandler to BaseHttpServer
* Generic enough to be used for many long poll services, not only the EventQueue.
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.
out which client connection has closed. So, in multi-region sims, things
can get messy fast.
This introduces a second parameters, which is a Scene object ref. Minor
adjustments to custom modules may be required due to this change.
- Set OwnerID = GroupID for deeded objects.
- Close a security loophole that would have allowed a user with deed rights in a group to deed ANY object to that group, even if it's not owned by them and/or not set to that group
- Set LastOwnerID correctly. Handle objects vs. prims correctly.
* This is necessary to avoid a dependency problem where LLStandaloneLoginModule references IInventoryService before the LocalInventoryServiceConnector is registered
* Correct some copypasta log messages in LocalInventoryServiceConnector
Several improvements in the connectors themselves.
Several improvements in configurations.
Needed to add a hack in IUserService and UserManagerBase, to be removed when that service is refactored.
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.
* Issue was that region server was silently dropping an XmlException caused by trying to deserialize the blank asset service response
* So make asset service return http status NOT FOUND rather than OK in accordance with REST
* and interpret this correctly in the async response so that a null object is sent back
* This means that this fix won't be active until both region simulator and server reach this revision
* If an oar save fails to get responses to all asset requests to the asset service then timeout after 60 seconds
* Timeout executes abort, since missing assets in an OAR seems bad
* This means that oar saves won't permanently hang and instead can be retried if something goes wrong with the asset service
* This is not a solution to mantis 3714. Hopefully a fix will be along shortly since I can now consistently reproduce that problem
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.
- fixes wild swings in memory usage related to usage of GetDrawStringSize()
We've been seeing wild swings in memory usage and a large chunk of
memory leak. From analysing this it's pretty clear that the mono
garbage collector is rather buggy! When exercised heavily it looks
like it frees more than its meant to resulting in crashes.
GetDrawStringSize() measures the size in pixels of text. To do this
memory for an image is allocated and used to call the GDI text
measure functions. Although no reference to the temporary memory
for the measuring is kept, it takes quite a while for the mono
garbage collector to clean up - so if lots calls to
GetDrawStringSize() are made at once there can be a spike in memory
usage. If the garbage collector is not fast enough then the GDI
layer runs out of memory. It also looks like the garbage collector
is not always reclaiming all of the memory.
I've attached an OpenSim patch which works around the garbage collector
issues. Instead of dynamically allocating memory for measuring
text sizes, it serialises (on a per region basis) access to a single
block of memory. The effect of this is to be nicer to the garbage
collector as it has a lot less work to do, at the cost of some
theoretical loss in performance (nothing noticeable with our tests
which hit it pretty hard).
OpenSim still does leak memory slowly, but it is a lot more stable
with this patch. I suspect that either the garbage collector misses
bits of freed memory or the GDI/cairo layer leaks a bit each time a
texture is created. Thats going to be a lot harder to hunt down, but
for reference if someone has OpenSim running on Windows it would be
interesting to see if it has the same problem as it would tell us if
its a mono/GDI problem or an OpenSim problem.
Modify dynamic texture handling so that an explicitly targetted
face is not scheduled for immediate expiration. The requirement
for precaching explicitly requires these assets to persist. They
do however remain temporary.
This approach leaves the legacy mode of operation (ALL_SIDES)
unchanged in this respect.
See the files: bin/config-include/GridCommon.ini.example and bin/config-include/StandaloneCommon.ini.example to configure and enable this caching method.

* unfortunately, while the client requires uuids and we want to be able to have arbitrary string ids, these cannot be kept in sync
* I think the problems last time were due to a serialization change
* So the major inteface version has been bumped to take care of any lingering issues here.
* This means that region servers beyond this revision can only connect to similarly uptodate grid services, and vice versa
* If you have something using XmlRpc that isn't in core, change your method signature from:
(XmlRpcRequest request)
to:
(XmlRpcRequest request, IPEndPoint remoteClient)
Changes to support client-side image pre-caching in the region. This
commit adds an additional calling sequence to the DynamicTexture data
and URL calls. The new interface allows a dynamic image to be loaded
into a specific object face (rather than the mandatory ALL_SIDES
supported today.
This is in part fulfilment of ticket #458.
The image render module is returning everything twice. Once with
data, once with null. This change adds a return to stop this
behavior. This was not apparent until I added a message to the
catching routine which issued a warning message when no data was
returned.
