Scripting & Server News Week 42

by

For the release candidate on Le Tigre we have some new information that comes from the wiki release notes just recently updated. Some of those are:

Havok Update

The Havok Physics Engine updates to version 2012.1 in the release candidate. In week 35 I reported that this version was coming. At the time we had just updated to 2010.x, I think. This update enables Havok’s terrain optimized that simplifies the physics shape of the terrain for improved performance. This feature can be disabled by region owners and estate managers with the Region Debug Console command “set optimize_terrain false“.

Some are reporting vehicle crossing are slower.

llGetSimStats

llGetSimStats() has yet to show up in the Linden Scripting Language (LSL)  pages of the wiki. Fortunately the release notes say:

Currently, this function accepts only [[SIM_STAT_PCT_CHARS_STEPPED]] as its parameter, which returns the % of Pathfinding characters skipped each frame, averaged over the last minute.  The returned value corresponds to the “Characters Updated” stat in the viewer’s Statistics Bar.

#SL News 1 Week 42

by

This Tuesday we got a roll to the main channel. This is the package that was on Blue Steel. This is the code to improve performance for Large Groups. It is not the Large Group Editing changes that Baker has made. Those changes are in a package still stuck in QA.

It has been quite since the roll out. That usually means things are working as expected.

Magnum

Is going to continue to run the same package it has had for the last couple of weeks. This is a package that adapts the simulator to the new hardware. It contains various configuration changes for the Denebian OS running in the region servers. I have no information whether this is identical to last week or some configuration settings are changing. Whatever the case, it is expected users won’t see any difference.

Server Updates

This last week we did get the roll to the main grid and a couple of small release candidates made their way to the RC channels.

The main channel got the package from Blue Steal as previously reported. That was a server crash fix package.

Server & Scripting UG Oct 2012

Blue Steel and Le Tigre got the same package, one that has some fixes for group SQL queries. These are not the Large Group Editing fixes. Those are still stuck in QA… I understand it is more the package they are in that is stuck rather than the actual group queries that are stuck. Simon Linden is NOT expecting the package with Large Group Editing to make it to an RC next week (42). Bummer.

Magnum continues to run last week’s (40) package, the backend infrastructure changes. The package that rolled to the main grid was added to this package. The combined packages will test this week.

The comments in the Deploys thread are few. So, it is probably safe to assume things are working well for everyone.

Viewer 3.4.x Problem

Oz Linden has given us some news on the crashing problem they have had with the Beta and Development viewer. The Lindens believe the current Beta viewer (3-4-1-265642) has the memory leak, or whatever, fixed. The crash rate is back to low rates.

For the techies, the problem had to do with how the cURL wrapper was threaded. The cURL thing has to do with computer network communication over networks. It is a programming library that makes it easier for programmers to implement communication protocols like HTTP and HTTPS. It helps with encrypting communications.

Wind Vectors Displayed – Red Lines

One more round of testing in the Beta viewer is in progress. Once completed the basic fix and changes will move to the main release viewer, likely next week (42).

It takes a couple of days of testing to collect enough data to make a determination on whether a fix is working or not. The current Beta Viewer was compiled on Saturday and released on Monday. If you have Auto-Update on, you got it before it was on the web site.

#SL Testers Needed Oct 11

Oskar Linden posted in the SL Forum requesting help testing some network changes. I suspect this is related to the Sudden Lag I’ve been writing about. See: Networking Optimization Pile On Test – October 11th Linden Lab has made some changes to the way regions handle network traffic. We need your help to test. This … Read more
