SL project updates 2016 51: server, simulator OS update

Server Deployment

While the No Change window was supposed to have come into operation on Friday, December 16th, there was indeed a deployment to the Main (SLS) channel on Tuesday, December 20th. It comprised the same server maintenance package as deployed to the RC channel in week #50, comprising internal logging changes.

The deployment means that all of the server channels on the main grid (Agni) are now running the same simulator version. As there are no planned deployments to the RC channels, all four channels should remain on this release until deployments resume after the holiday period.

SL Viewer

We might see a 64-bit project viewer appear during the week. However, at the time of writing,  the list of viewers in the various pipelines remains as:

  • Current Release version: 5.0.0.321958, dated December 1st, promoted December 5th – formerly the Project Bento RC viewer.
  • Release channel cohorts:
    • Maintenance RC viewer, version 5.0.1.322219, dated December 9th – some 42 fixes and improvements + Bento support
  • Project viewers:
    • 360-degree snapshot viewer, version 4.1.3.321712 dated November 23rd – ability to take 360-degree panoramic images – hands-on review
  • Obsolete platform viewer version 3.7.28.300847 dated May 8, 2015 – provided for users on Windows XP and OS X versions below 10.7.

Bento Support

With the release of Kokua for Second Life 5.0.0 and RLV 2.9.21 (see my article here), the following currently maintained viewers all have Bento support: Black Dragon, Catznip, Cool VL, Firestorm, Kokua for Second Life, Restrained Love. Alchemy is expected to update to include Bento “soon” and UKanDo is still awaiting a complete overhaul.

In terms of clients with 3D viewing capabilities, Radegast has been updated to support Bento, but the update is pending release. Lumiya for Android will have Bento support added “soon” (Lumiya 3.3 with Voice support released on Sunday, December 18th, and my review is available here).

Simulator OS Update

The Lab is in the process of updating the operating system on the simulator servers. At the moment the new OS version is installed on a number of regions on Aditi (the beta grid), including: Fire Ants 1, Fire Ants 2, Grasmere, Oak Forest, and Twilight Shores, not all of which are open to the public.

“This is one of those ‘features’ that might perform a bit better, but otherwise is a success if it behaves exactly like our current servers,” Simon Linden said at the Simulator User Group meeting on Tuesday, December 20th.

“We’re in the starting process of testing things. We have a lot of testing to do. [We’re] updating from an old version of Linux to a not-so-old version of Linux,” April Linden added. “Just to keep things moving. All the usual reasons. Performance updates, security, etc.”

Second Life hits a lot of low-level server code hard, including networking, memory and multi-processing. The overall hope is to have the newer revisions of the operating system will improve these. Expect this work to reach Agni in early 2017.

Group Chat

Group chat was long a bane of Second Life. In 2014/15 however, the Lab put a considerable amount of work into improving things, although some issues remain. One of these is that if an individual role outside of the default “Everyone” has a very high number of group members assigned to it (e.g. several thousand), it can dramatically impact things like group chat performance and can prevent the members’ list loading. One solution might be to delete the role (converting those in it to Everyone).
