Cloud Uplift

Region Testing

As the Lab has announced, and I’ve reported – see Play Linden Realms in the cloud and help the Lab, the Linden Realms have been cloned to Aditi and are running on AWS  servers. Interested users are asked to help in testing the regions by logging-in to Aditi and spending time playing the game. Follow the links above to find out more.

LSL HTTP Changes

As a part of the move to AWS services, there will be changes to the use of HTTP once cloud-hosted simulator come into use. It is Linden Lab’s hope that these changes will not cause significant issues, however, in order to provide scripters with as much information as possible, Oz Linden posted a forum update providing an outline of the areas of impact: llHTTPRequest – Outbound HTTP and lRequestURL or llRequestSecureURL.

A number of regions on Aditi have been set-up to allow for testing, comprising:

  • Morris
  • Cloud Sandbox 1
  • Cloud Sandbox 2
  • Cloud Sandbox 3
  • Cloud Sandbox 4

Further information and the continuing discussion can be found within the forum thread.

Changes are coming to LSL HTTP calls – for details please refer to LSL HTTP Changes Coming

Group Chat

People continue to experience issues with group chat disconnecting / failing following a transition to a different region via vehicle or teleport (see BUG-229219). As per last week’s update, there is a potential fix for this issue in the works, but whether or not it solves all of the issues currently being experienced or not is an unknown until it is actually deployed.

2020 Simulator User Group week #37 summary

Eris Isle, July 2020 – blog post

The following notes were taken from the September 8th Simulator User Group meeting.

Simulator Deployments

Please refer to the server deployment thread for news and updates. However, there are no planned deployments for week #37.

SL Viewer

On Tuesday, September 8th, 2020, the following viewers were updated:

  • The Bormotukha  Maintenance RC viewer updated to version 6.4.8.548394.
  • The Mesh Uploader RC viewer updated to version 6.4.8.548061.

The rest of the viewer pipelines currently remain unchanged from the end of week #36:

  • Current release viewer version 6.4.7.546539, dated August 11, promoted August 17, formerly the Arrack Maintenance RC viewer – No Change.
  • Release channel cohorts:
  • Project viewers:
    • Project Jelly project viewer (Jellydoll updates), version 6.4.8.547487, issued August 26.
    • Custom Key Mappings project viewer, version 6.4.5.544079, June 30.
    • Copy / Paste viewer, version 6.3.5.533365, December 9, 2019.
    • Project Muscadine (Animesh follow-on) project viewer, version 6.4.0.532999, November 22, 2019.
    • Legacy Profiles viewer, version 6.3.2.530836, September 17, 2019. Covers the re-integration of Viewer Profiles.
    • 360 Snapshot project viewer, version 6.2.4.529111, July 16, 2019.

Region Crossings

The recent updates to region crossings have generally improved things, but they’ve also led to a lot of “interesting” – to use Simon Linden’s term – side effects and some unpredictable behaviour.

  • Some are reporting a possible increase in avatar / vehicle collisions when crossing into regions with damage enabled.
  • Others are reporting issues of crossings “hanging” – the vehicle vanishes, the avatar is unable to move, communication, teleport, stand, etc., while the user is still able to cam around but is unable to to cleanly log-out.

This second issue apparently particularly noticeable when the region being entered is not visible at the time of the crossing (see BUG-229312), although this factor may be a separate issue to anything related to region crossings.

Group Chat

People continue to experience issues with group chat disconnecting / failing following a transition to a different region via vehicle or teleport (see BUG-229219).

There is a potential fix for this issue in the works, but whether or not it solves all of the issues currently being experienced or not is an unknown until it is actually deployed.

In the meantime, the group chat issue may be related to to issues being experienced with bots using group chat becoming unresponsive,sometimes after little more than an hour of running.

All of these issues appear to date from a period of back-end updates made in early August.

Cloud Uplift

Questions continue to be asked about changes that will / may be made to simulator services as a part of or immediately following the uplift work to get simulators transitioned to AWS services.

As has oft been stated by the Lab (and reported in these pages), the Lab’s focus is on successfully transitioning all of their services  – including simulators “as is”, without making substantive changes at this point in time. As  Oz Linden stated during the meeting:

Uplift is trying very hard not to make any changes we don’t _have_ to make … A big driver for getting simulators uplifted is that then we can start selling regions again … believe me, that’s pretty great motivation.  When and whether we’ll make other changes to optimize or exploit the cloud is later on.

2020 Simulator User Group week #35 summary

Cascadia, June 2020 – blog post

The following notes were taken during the Simulator User Group meeting of Tuesday, August 25th, 2020.

Simulator Deployments

Please refer to the server deployment thread for news and updates:

  • On Tuesday, August 25th, the majority of servers were updated to server maintenance update 547110, previously deployed to the RC channels comprising updates to assist with the cloud uplift.
  • On Wednesday, August 26th, there will an RC deployment with version number still TBA at the time of writing, so please check the deployment thread for update. This should  comprise, in the words of Rider Linden:
We hope will help with test pilots being cut in half by their helicopters and other such unpleasantness. There may still be a few issues with unexpected collisions on a region crossing. But we think we have most of the cases. That is going out to LeTigre at least, we may put it on other channels also.

SL Viewer

The have been no official viewer updates to mark the start of the week, leaving the pipelines as follows:

  • Current release viewer version 6.4.7.546539, dated August 11, promoted August 17, formerly the Arrack Maintenance RC viewer – NEW.
  • Release channel cohorts:
  • Project viewers:
    • Custom Key Mappings project viewer, version 6.4.5.544079, June 30.
    • Copy / Paste viewer, version 6.3.5.533365, December 9, 2019.
    • Project Muscadine (Animesh follow-on) project viewer, version 6.4.0.532999, November 22, 2019.
    • Legacy Profiles viewer, version 6.3.2.530836, September 17, 2019. Covers the re-integration of Viewer Profiles.
    • 360 Snapshot project viewer, version 6.2.4.529111, July 16, 2019.

In Brief

  • The improvements to region crossings have resulted in a race condition that mean the receiving region can start acting on a vehicle (running scripts, etc), before avatars are correctly re-seated. As noted, the RC deployment in the planning for Wednesday, August 26th, should help with addressing this.
  • Further thought is being put into how to improve region crossings further, but there will always be limits to what can be achieved due to the nature of the beast (handling data between two region simulators and the viewer), as Mazidox Linden pointed out:
Ultimately moving data blobs around takes time. Moving a lot of data blobs around to a lot of different places at once takes a lot of time and a lot of complexity. It’s never going to be totally seamless without I-Don’t-Want-To-Think-About levels of rearchitecting. And I’m sure even that would come with trade-offs.

Maxidox Linden, SUG Meeting, August 25th

  • HTTP-out restrictions remain in place on the Aditi regions running on AWS infrastructure. Work is progressing on code that will allow these restrictions to be lifted, although the implementation (when ready) will come in stages. One of these stages will be to make the new HTTP-out code available on regions still in the Lab’s co-lo (Aditi first, then Agni) to allow for more widespread testing.
