#SL News 2 Week 48

by

We had a roll back of the release channels this Thursday. SO, if you are wondering what happened, here is the story.

Quoting Maestro Linden in Thrusday’s Beta Server meeting, “So, let’s go over releases a bit.

This week was pretty ‘exciting’. The main channel got a maint-server that had been in RC for 2 weeks, which mostly included bugfixes. That went pretty smoothly.

However, on Wednesday we ran into some issues with the new code. We’d planned to put new code in all 3 RCs, and we took care of Blue Steel and Magnum, but by the time we got to Le Tigre, the grid was sick (unrelated to the new code), so Coyot aborted the Le Tigre roll.

Then there were reports in the forums about offline IM emails from objects being broken; if an object sent you an IM and you were offline, the offline email would contain all the usual details *except* for the message this bug affected both Blue Steel and Magnum since they both shared the responsible change.

Then, after digging into offline emails a bit more, we noticed that the ‘To’ field of offline emails would show the object owner’s name instead of the recipient’s name. So it would be like “To: Motor Loon <so***********@***il.com>” which was a little confusing 🙂 Fortunately they went to the right person at least.

Anyway, these bugs were kind of bad, but we weren’t sure that they were worth the trauma and downtime of an emergency rollback. But then this morning, we became aware of a 3rd bug, from support. It turned out that deeding parcels to groups was failing. That was the main cause for the rollbacks this [Thursday] morning.

So, now we’re back to Server 12.11.09.266804 on all 4 channels.

Kelly was pretty quick with bug fixes for those 3 issues, but they’re still in testing. We hope we can try again next week.“

#SL Viewer Update Week 48

by

SL Viewer Updates

It seems the memory leak problem has finally been solved for the SL Viewer. We’ve had a number of false hopes that it was fixed. But now the main production viewer has updated. That is a sure indication the problem is fixed. That does not mean every problem is fixed. But, the problem causing a high crash rate in the Beta & Dev viewers is fixed. So, fixes can now start to roll again. For the last few weeks updates had stopped while the problem was tracked down. So, we sort of have open floodgates and a surge of updates rolling out. Viewer versions are changing quickly.

The Development viewer is at version: 3.4.4-267322

The Beta viewer is at version: 3.4.3-267135 – Release Notes

#SL ADITI Grid Problems

by

ADITI is the preview grid for Second Life. This is where we test new scripts, mesh items, and lots of other stuff. It is popular with creators because uploads are free. Currently people are having problems logging in. The problem is caused by the hard drives for the ADITI database filling up.

Take-Away:

There will be discussion at Thursday’s Beta Server meeting on what may be the best solution for the problem. If you use the preview grid, you will probably want to be there for that meeting.

Discussion in the SL Forum: ADITI Problems Thursday Meeting

Details:

ADITI is smaller than the main grid and runs on less hardware. The database for assets on the ADITI is much smaller, hardware-wise. Oskar Linden, no longer on staff, was handling keeping the grid running. But, the situation required manual cleaning of the drives. Now that is proving a problem.

#SL News Week 48

by

This week following the Thanksgiving holiday we move back to the regular server updates. The Main Channel gets the maintenance package that was running on all three release candidate channels. This package has the fix for linksets and objects larger than 64 meters. (BUG-166 – Something invisible pushes avatars around.)

Server Scripting Meeting November 2012

While some saw linksets larger than 64m as a good thing, it was being used to grief people and also accidentally causing problems. With this release the problem is ‘fixed’.

A Strangeling in Second Life

by

Strawberry Singh  has a post about a new game, Strangelings, expected to be out the first quarter of 2013. She says the Ozimals team has joined up with two former Lindens and a financial expert to form Flying Monkey Interactive, Inc. The team is developing a product platform called Toto that will run on iPad, the web, iPhone, and Facebook.

Strawberry Singh as a Strangeling

The Magic of Oz region has been remade to create a promotional and information spot in Second Life. It is an all mesh area. Check it out. Also bounce over to Strawberry’s blog and see the video she made. It shows the Strangling in all is awesome cutness: Strangelings & Mesh Oz!

#SL Mesh Deformer Status II Week 48

by

There is an issue for some with the Mesh Deformer and the time it needs to calculate the mesh for offsetting. Kitsune Shan has been working with the Deformer and voicing concern about the time needed for the Deformer to kick in.

Kitsune Shan

Kitsune is proposing that we do something like what is done with avatar baking. The viewer does the bake and sends a composite image to the servers for everyone else to use. Of course that is being changed to a server side process now, where a new service in servers at the Lab will do the bake and send out the composite image. Kitsune would like to see something similar to that for the Mesh Deformer.

White Rabbit points outthe difficulties with attempting to cache the deformation calculations. White Rabbit has done some testing and finds the CPU time for the Deformer calculation is consistently small. She speculates that the long calc times come from the thread being a low priority process.

White Rabbit

The chances that Deformer calc’s will be cached server side is, in my opinion, slim to none. We do not have any statistics on the type of hardware being used with Second Life™. We know there is new stuff, way old hardware, and everything in between. But, AFAIK, we have no information on how much of each.

We have been told that number of users staying with SL Viewer 1.23.x is only 2 or 3%. Third Party Viewers that do not use SSE2 CPU commands is small. Read the SSE2 thing as meaning viewers that support really old computers. Their user bases are so small they fit within the 2-3% too. So, I’ll speculate that the Lab is not going to put much effort into something as complex as caching deformation data.
