SL projects update week 40 (1): server releases, group ban list, interest list

Server Deployments – Week 40

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

Second Life Server (Main Channel)

There have been no updates to the Main channel.

Second Life RC BlueSteel, RC Magnum, and RC LeTigre – Wednesday October 2nd

All three RCs should receive the same maintenance package comprising:

  • A fix for a bug affecting group notice delivery to large groups whereby the notice randomly fails to reach some group members
  • Interest list preparatory work for more correct sort order during scene load
  • New JSON_DELETE option to llJsonSetValue(), for deleting elements in JSON strings. Usage: ‘string output_json = llJsonSetValue(string input_json, [list location, JSON_DELETE)’ will delete the element specified by the location argument

Release notes: BlueSteel, LeTigre and Magnum.

Region Crossing Issue Update

Speaking at the Simulator User Group meeting on Tuesday October 1st, Andrew Linden reported that both he and Maestro had been looking into the recent problems with region crossings which have been hard to pin down to a specific cause. However, Andrew was confident one cause had now been identified, saying:

It appears that there is a bug when vehicles cross region boundaries on parcels with autoreturn. “In particular, if the vehicle has been on the parcel long enough to trigger autoreturn, it won’t actually get autoreturned because someone is sitting on it. But when it tries to cross the region boundary with the rider things fall apart.

Simon Linden indicated he had a proposed fix for the issue, which he wanted to discuss with Andrew outside of the meeting, but hopes that the fix will be in a position to be deployed in week 41 (commencing Monday October 7th).

Group Ban List

The obligatory Baker Linden shot :)
The obligatory Baker Linden shot 🙂

Following-on from the update given on his behalf at the TPV Developer meeting on Friday September  27th, Baker Linden appeared at the Simulator User Group meeting to provide a rapid-fire update on his latest state-of-play with the group ban list work (see JIRA VWR-29337):

Today I’ll be working on merging the viewer code with what’s in release, and I’ll be working on getting up some actual builds to deploy to a grid for internal testing (it is not Aditi yet). so by the end of the day, I should have all the components deployed and ready for internal testing, and depending on how well that goes, it’ll be ready for Aditi soon!

In terms of the viewer code becoming visible, Baker believes his project viewer repository will become visible soon, most likely around the time of the next TPV developer meeting, when he is due to explain the new functionality.

In the meantime there’s still some further work required on the code, as he explained. “There are still a few small bugs and issues I have to work on in the code — I’ll be working on those while internal testing is happening. There’s a major refactor in llpanelgroupinvite, which is what I’m trying to hand-merge today.”

Interest List Work and Video

Andrew Linden has been finishing-up on some additional interest list work, and is now looking to produce a video showing the “before” and “after” scene loading within a region. The “before” part of the filming is already in the can, but the region he used is now “long gone”, and so he picked-up a few suggestions from the Simulator group on regions which may offer go locations for shooting the “after” segment of the film. Essentially he’s looking for regions with lots of objects be which are not ridiculously overloaded with textures.

Other Bits

Render Weights and Calculations

Work has been going on around the issue of render weights and how they are calculated. The current Maintenance viewer has code for a new “automatic avatar render limit and feedback system”.

Que Niangao raised concern at the meeting and on the SLU forum that a constant forming a part of this system – OBJECT_RENDER_WEIGHT, which requires feedback from the viewer, and so might be used for grefing people; such as through a viewer tweaked to return highly inflated numbers for others in a region, thus allowing it to become a tool for griefing.

Responding to Que’s enquiry, Simon Linden said, “Yes … OBJECT_RENDER_WEIGHT needs to be used carefully. First, the way that is calculated is likely to change … I’m going to be working on it today, in fact.”

He went on to indicate that he’s been gathering data on avatar weightings (samples from about 500 avatars) which he’ll be using to make the changes, although he may be seeking further assistance. The changes he’s looking to make are on the server, but he was a little circumspect on details out of concern that going too deeply into how things work on the server as do so could make it easier for the unscrupulous to game the system.

One area where the new system will hopefully have an impact is in preventing the use of worn sim laggers impacting a region as can currently be the case.
