2018 SL project updates 13/1: Simulator User Group

Soul2Soul River; Inara Pey, February 2018, on FlickrSoul2Soul Riverblog post

Server Deployments

As always, please refer to the server deployment thread for the latest updates.

  • The Main (SLS) channel was updated on Tuesday, March 27th, to server release 18#18.03.14.513292, containing the new server capabilities (see below).
  • At the time of writing, the Release Candidate channels were all TBD regarding potential deployments. This report will be updated if the deployment thread provides further information on the RC channels.

New Capabilities

The new capabilities in 18#18.03.14.513292 for the Main (SLS) channel is the first part of a set of server and viewer updates.

  • The new IM cap is to overcome of off-line IMs failing to be delivered when a user logs in. Currently, these are delivered via UDP, whether or not the viewer is ready to receive them. With the new capability (once grid-wide and implemented within the viewer), the viewer will request off-line IMs, which the server will package and deliver to the viewer via HTTP.
  • The new abuse report cap will replace the need for the viewer to have AR categories hard-coded into it. Once fully deployed, and a viewer update released, it will mean the view will request the current list of AR categories from the server when starting up, making the management of the list easier, and hopefully reducing the number of ARs filed under outdated categories.

Updates to the viewer incorporating these changes will be made available by the lab in the near future.

SL Viewer

  • The Maintenance RC viewer updated to version 5.1.3.513630 on Friday, March 23rd.
  • The Media Update RC viewer updated to version 5.1.3.513644, on Tuesday, March 27th.

The remainder of the pipeline remains as:

  • Current Release version 5.1.2.512803, dated February 23, promoted March 1 – formerly the Nalewka Maintenance RC – No change
  • Release channel cohorts:
  • Project viewers:
  • Linux Spur viewer, version 5.0.9.329906, dated November 17, 2017 and promoted to release status 29 November – offered pending a Linux version of the Alex Ivy viewer code.
  • Obsolete platform viewer, version 3.7.28.300847, May 8, 2015 – provided for users on Windows XP and OS X versions below 10.7.

In Brief

First Name / Last Name Changes

This is still a long way off from being implemented, however, Oz Linden confirmed llDetectedName() will return the current name for an avatar, no matter what the change. However, it may take some time for it to change everywhere due to caches.

More on the return of last names and name changes, please refer to The return of Second Life Last Names – update with audio.

SL Messaging Layer

Simon Linden is looking into the Second Life messaging layer, which may be the problem behind a lot of “lag” issues. “There’s actually a number of small improvements I want to make, but I’m being careful to do them one at a time and have real data showing it gets better,” he said in providing an update on the work.

Friendship Offers Failing

Some are experiencing Friendship offers failing, even when the offer is accepted – see BUG-215977. According to Simon Linden, this might require a server-side update to fully correct.

Region Crossings

Simon Linden has been looking at vehicle region crossings alongside of  Joe Magarac (animats) testing with the viewer (See Firestorm JIRA FIRE-21915, BUG-214653, this SL Forum thread, this Google document, and my update here for more).

Part of the issue, a previously noted, is viewer / simulator communications. If these are suffering latency or packet loss, then things can get rough with vehicle region crossing very quickly. This is something Joe has been trying to compensate for by introducing a script that turns off physics and freezes the vehicle when received by a new region until it can confirm the associated avatar data has arrived.

Unfortunately, excising the viewer from region crossing data handling would be difficult, as it has to be involved to move and change its primary connection for an avatar. It would take a major protocol change to remove the viewer from the region crossing loop and separate connection hand-off from crossings. Further, if such a protocol change were to be made, it would require more work to support both new and old until enough viewers get updated.

Mainland Price Restructuring

While the Lab does not issue numbers, Oz Linden indicated at the Simulator User Group meeting that since the Mainland Price Restructuring, “mainland ownership is up quite significantly.”
