SL projects update 24 (3): New object return LSL capabilities

Posted on by Inara Pey

Update June 12th, 22:40 BST/14:40 SLT: The BlueSteel  / LeTigre deployment which includes these capabilities has been rolled back due to an issue whereby objects cannot be rezzed in BlueSteel / LeTigre parcels which disallow object entry (even if Create Objects is enabled) – BUG-2850. Both regions are now running the week 24 Magnum deployment.

In week 23, Kelly Linden announced new LSL capabilities for the scripted return of objects within a region / parcel.  In making the announcement, he indicated the capabilities would be available “some time in the future”, a comment which appears to have been a little overly cautious, as the new functionality received its first outing on the Main channel in the RC deployments to BlueSteel and Le Tigre on Wednesday June 12th.

The new object return functions are llReturnObjectsByOwner and llReturnObjectsByID, and are designed to be used to enable the automated return of specified linksets to their owners.

The object containing scripts using the functions can either be placed in the land, or worn as an attachment but will only work on land held by the object owner.

The primary aim of these functions is to make for easier clearing of private sandboxes and rental parcels in cases where previous users / tenants may have left objects behind on leaving (thus removing the onus on the land owner to locate and manually return items).  They are not intended as anti-griefing tools, nor are they a “replacement” for the parcel / region auto-return functions.

The Functions

The functions are defined within the BlueSteel and LeTigre release notes as follows:

Additional Notes and Q&A On Capabilities / Limitations

There are also some additional notes which go with the new functions:

  • There are no cases where one of these new LSL calls would return an object that you could not manually return yourself
  • The functions will only work on objects in the same region/parcel as the object containing the script using them. Objects which are returned are coalesced in the recipient’s inventory, rather than being returned as individual objects
  • The functions work if and only if the user would have permission to return the object via the viewer, and it does not handle encroachment
  • To prevent severely damaging accidents the mass returns by owner (llReturnObjectsByOwner) will not work for your own items, items owned by an estate owner or manager or items that are owned by the group the land is ‘set’ to
  • llReturnObjectsByID will not return objects owned by the parcel owner
  • In order to work on group-owned land the object containing the script using the functions must be deeded to the group by the group owner
  • The return capabilities are throttled to a maximum hourly quota based on a parcel’s Land Capacity (under About Land > Object). So, if your Land Capacity is 500, then using these LSL functions you can return up to 500 linksets per hour
    • The throttle is there primarily to prevent a silent war between a rezzer and returner that could impact the back-end servers
    • Even with the throttling, it is anticipated that the functions should be able to return everything on your land within a region in one go, but not necessarily more than once an hour for large-scale returns.

SL projects update week 24 (2): server news

Posted on by Inara Pey

Update June 12th, 22:40 BST/14:40 SLT: The BlueSteel  / LeTigre deployment which includes these capabilities has been rolled back due to an issue whereby objects cannot be rezzed in BlueSteel / LeTigre parcels which disallow object entry (even if Create Objects is enabled) – BUG-2850. Both regions are now running the week 24 Magnum deployment.

Server Deploys for Week 24

As always, please refer to the week’s forum deployment thread for news, updates and feedback.

Second Life Server (Main) Channel

On Tuesday June 11th, the SLS channel received getting the server maintenance project that was on BlueSteel and LeTigre in week 23. This is intended to fix a simulator crash mode, and address a disconnection issue whereby multiple avatars would be disconnected from a simulator simultaneously, giving the impression the region had crashed when it had in fact not done so, and which also impacted LSL HTTP-in URLs.

Following the deployment, there was a report that the disconnection issue fix had not fully addressed the problem of LSL HTTP-in URLs being dropped, which was also raised at the Simulator User Group meeting on Tuesday June 11th. The matter has been acknowledged by Kelly and Maestro Linden, who are currently awaiting further information on the problem, although Simon Linden also commented, “I realize a bug Kelly and I were talking about earlier today is that issue, so someone is on it.”

BlueSteel and LeTigre Release Candidate Channels

On Wednesday June 12th BlueSteel and LeTigre should receive a new server maintenance project to fix a number of crash modes, addresses an issue with neighbouring region visibility, and adds new LSL pathfinding capabilities and object return capabilities:

  • The new pathfinding property CHARACTER_STAY_WITHIN_PARCEL, which I described in week 19. can be used with llCreateCharacter() and llUpdateCharacter(), and is intended to help with keeping characters within parcel boundaries
  • The new object return functions I reported on in week 23, namely llReturnObjectsByOwner and llReturnObjectsByID, are intended to provide an automated means of returning objects to their owners. For ease of reference, I’ve provided a more in-depth look at the capabilities in a separate report. Kelly Linden has also includes some guidelines on the functions in the deployment discussion thread.

Magnum Release Candidate Channel

On Wednesday June 12th Magnum should receive an update to the current interest list changes running on that channel, which addresses two bugs introduced by the project. Providing no further issues are found with these changes, it is likely (but subject to confirmation) that they will be promoted across the grid in week 25.

Commenting on the Magnum update at the Simulator User Group meeting on Tuesday June 11th, Andrew Linden said, “The Magnum channel has two bug fixes. The excessive AvatarAppearance packets [in which the simulator would send many unnecessary AvatarAppearance messages to the viewer], and my final fix for Meeroos; specifically, the problem where it looks like the Meeroo’s animation is busted when you turn around to look at it.”

Going on Andrew’s recent comments, this update is liable to mark the final aspect of server-side interest list work for the moment.

The Magnum deployment also includes a fix for the issue relating to viewing the text of large scripts I reported on in week 23, whereby the text of previously saved “large” scripts cannot be displayed in the script editor for users on slow connections (BUG-2694). This update had originally been targeted at the week 23 deployments, but failed to make the cut then due to some last-minute work being required.

Group Ban List

Baker Linden
Baker Linden

The group ban list functionality Baker Linden has been working towards in his desire to address JIRA SVC-8127 may soon start to get attention. Commenting at the Simulator User Group meeting on Tuesday June 11th, Baker said:

I am getting closer! I haven’t started work on it directly, but I’m wrapping up the last of the bug fixes related to Mute Lists. I’m writing some new unit tests to test my new functionality … There might be some viewer / other backed server work to do too, but hopefully everything will work so that part will be smooth. But after I finish up this last issue, I’ll be working on group ban stuff. I’ve learned a ton about Django and how to implement it, so I’m hopeful that it’ll be somewhat smooth of an implementation.

Django is a web framework the Lab uses for a number of in-world user-related services, and is the chosen mechanism by which to add the ban list functionality (its use doesn’t mean the group ban function will be web-enabled or anything like that). It is also a tool set unfamiliar to Baker, who only started finding his way around it a few weeks ago.

JSON Wiki Update

New LSL capabilities were recently introduced for the creation and parsing of JSON formatted strings which can used for transferring data between in-world objects and external resources / websites.  The LSL-JSON pages on the Second Life wiki have been evolving over the past few weeks, with the most recent updates occurring on June 10th. If you’re interested in these new capabilities, make sure you take a look at the wiki.

SL projects update 24 (1): Viewer news – materials, SSB/A, deformer, snapshots

Posted on by Inara Pey

Update: In further tests of the FIRE-9097 “fix” at lower resolutions (e.g. 2650 pixels across), I found it can re-introduce the tiling artefacts in snapshots.

General Viewer News

Materials Processing

The release of an update to the materials beta viewer on Wednesday June 5th (3.6.0.276961) was followed at the weekend by the arrival of a further beta version – 3.6.0.277049 – with accompanying release notes. Commenting on the rapid-fire releases, Oz linden said at the Content Creation User Group meeting on Monday June 10th, “We’re getting close to the end of its beta cycle (or put another way… report your bugs now).”

Snapshot Issues

We’re all aware of the snapshot tiling issue which plagued SL photographers for a good while, which would leave “tiling” artefacts on images taken at higher resolutions than the user’s monitor resolution when running in deferred mode (now known as Advanced Lighting Model). A fix for this issue (MAINT-628) finally reached the public in late 2012, but brought with it some additional issues. On of the most notable of these was the appearance of black rectangles in very high resolution images.

This latter problem most recently caused an additional outcry when the LL “tiling” fix was finally incorporated in Firestorm viewer earlier in 2013, with many users incorrectly blaming the Firestorm team for the problem.

Well, for all and sundry, Firestorm users or otherwise, there is some potentially good news on the horizon.

Commenting on the broader issues reported with snapshots duing the Open-source Dev meeting on Monday June 10th, Oz Linden said:

It looks like there are fixes in the MAINT pipeline for those. I don’t know how soon those will be out… I can try to find out if they have a project build ready.

Additionally, there is further news specifically for Firestosm users. While it is somewhat outside the scope of “SL project news”, it is neverthless reporting here.

Nicky Dasmijn has been working on the problem, and has implemented a fix for the issue (see Firestorm JIRA FIRE-9097), which should correct matters for snaps of up to 4096×4096 pixels without any “rectangle” artefacts appearing or with any regression to issues of tiling, and which may work at high resolutions than that for some.

Firestorm image artefact fix: image at 6000 pixels across, saved as PNG – note rectangle artefact (click to enlarge)

I tried a very rough-and-ready test of the fix. I found that capturing images up to 5,000-5,600 pixels across with the aspect ratio maintained worked OK for me. Anything around 6,000 pixels across saw JPG images save OK, but rectangle artefacts begin to appear when saving in PNG (see both images on the right)

However, as I’ve recently been experiencing other GPU issues, I’ve been unable to ascertain if the rectangles are down to an issue with the code or simply a matter of my GPU running out of resources when processing PNG images above 5600 pixels across.

The fix is currently in a recent Firestorm pre-release, and will hopefully make the cut for the next formal release. It is currently unclear whether the code has been / will be contributed to LL, and if so, whether they will adopt it or opt to go with their own forthcoming updates (as indicated by Oz in his statement above) or opt to combine it with their own fixes (depending on the nature & scope of the latter).

Future “STORM Project Viewer” Release

There are a number of code contributions which have come via the Snowstorm route which have been queued awaiting a suitable release. These cover a range of additions to the viewer, and example of which is STORM-68 (As a Builder, I want that ability to set default permissions on creation of objects, clothing, scripts, notecards, etc.).

Commenting on STORM contributions in general, and in light of the forthcoming changes to the viewer release process, Oz said, “I’m trying to get all the storm issues merged up so that I can be ready to put out a project viewer as soon as the new viewer version manager is deployed.” Whether STORM-68 (which is apparently seen as “largely good to go”, although it may also require a server-side change), or the fixes for snapshot issues mentioned above will be among them remains to be seen. However, a “STORM” project viewer could well be adding even more features to the SL viewer in the near future.

Second Sol Regatta readying for Relay for Life

Posted on by Inara Pey

Over the next two weekends the Sail4Life Second Sol Regatta will be taking place as a part of the overall Sail4Life fundraising work for Relay for Life.

Over the course of both weekends some 20 teams of between one and four sailors will race one another using an all-mesh sail boat donated for the regatta by Jacquline Trudeau of Trudeau Yachts. The Trudeau Patchogue II sailboat is a lovely little boat which is fast and manoeuvrable, and should be well-suited to the event (I recently had fun skipping around in one of the demos!).

banner

The first round of qualifying races will take place on Friday 14th and Saturday 15th June, over a range of courses as follows:

  • Friday June 14 12:30 SLT: Nantucket Yacht Club-SL, Atlantic raceline  Race Directors: Jean Quartz, Gemma Vuckovic
  • Saturday June 15 09:00: North Sea/ EYBC, Breadnut raceline.  Race Director: LlDewell Hawker
  • Saturday June 15 12:00: Triumphal Yacht Club, Faragut raceline.  Race Director: SerenityAeon
  • Saturday June 15 15:00: Danshire Yacht Club, Queequeg raceline.  Race Director: Hay Ah
  • Saturday June 15 18:00: Fishers Island Yacht Club, Plum Gut raceline.  Race Director: Jane Fossett.

There will be further heats on Saturday June 22nd, with the top crews from the various heats then competing in the finals on Sunday June 23rd, after which there will be an award ceremony and closing party.

Full details of the courses and participating crews can be found in the SL Sailing Forum. spectators are welcome, but are asked to keep clear of the race routes (see the maps on the forum thread), and not to touch the boats participating in the races. There are viewing areas at the various yacht clubs supporting the event, such as at the Danshire Yacht Club quayside as well as the other participating yacht clubs, and spectators will be able to donate to RFL.

Those interested in trying-out the Trudeau Patchogue II sailboat can do so by availing themselves of a timed demo version which can be obtained from the following two locations: The Trudeau Yacht Yard, and the dock at Danshire Yacht Club in Knaptrackicon.

About Sail4Life and the Second Sol Regatta

Sail4Life has always been a strong supporter of Relay for Life, and in 2012, it raised L$2.34 million through a series of events held across the RFL of SL season, including regattas, races, auctions and other events, as well as a strong presence at the RFL of SL weekend. The Second Sol Regatta 2013 promises to present another great page in the history of the SL sailing community’s support for RFL.
