2020 Simulator User Group week #41 summary (w/uplift)

Broken, August 2020 – blog post

The following notes were taken from the October 6th Simulator User Group meeting.

Simulator Deployments

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

  • There are currently no planned deployments for week #41. An RC update that had been planned had to be pulled after QA found an issue when attempting to uploading items that had been previously uploaded and edited.
  • This means that Some RC regions should be started during the Wednesday, October 7th deployment window, but they will not receive any updates.

SL Viewer

There have been no updates to the current list of official viewers, leaving the pipelines as follows:

  • Current release viewer :Love Me Render #4 (EEP fixes), version 6.4.9.549455, released September 24th, promoted September 28th – No Change.
  • Release channel cohorts (please see my notes on manually installing RC viewer versions if you wish to install any release candidate(s) yourself):
    • Cachaça Maintenance RC viewer, version 6.4.10.549752, issued October 1st.
    • Mesh uploader RC viewer, version 6.4.10.549686, October 1st.
  • Project viewers:
    • Project Jelly project viewer (Jellydoll updates), version 6.4.10.549690, October 1st.
    • Custom Key Mappings project viewer, version 6.4.5.544079, June 30th.
    • Copy / Paste viewer, version 6.3.5.533365, December 9th, 2019.
    • Project Muscadine (Animesh follow-on) project viewer, version 6.4.0.532999, November 22nd, 2019.
    • Legacy Profiles viewer, version 6.3.2.530836, September 17th, 2019. Covers the re-integration of Viewer Profiles.
    • 360 Snapshot project viewer, version 6.2.4.529111, July 16th, 2019.

Cloud Uplift

More regions on the main (Agni) grid are being noted as being on AWS (see my previous TPV Developer meeting and CCUG meeting notes). As a result some are (prematurely) proclaiming this to be a sign that “the end of the uplift work is in sight”; however, Oz Linden sobered such statements, commenting:

I’m not sure that we’re at the beginning of the end … but we’re past the end of the beginning.

To which Mazidox Linden added:

We’re currently running some tests with production data on AWS regions, yep. … There are definitely some outstanding issues we’re aware of, and more we’re probably not (yet) that we’re trying to shake out.

One aspect of the current situation is that while there may be some regions with associated experiences running via AWS, the core data handling for experiences still lies within the Lab’s co-lo facility; this may affect the experience performance in those regions, but should be rectified as the uplift work continues.

In terms of when specific aspects of the uplift will be “completed” (remembering that LL is looking to have a majority of the work done by year-end), Oz Linden further commented:

We’re lifting as quickly as we can, consistent with checking for problems. So far it’s going better than expected, but making any prediction would jinx it.
For the curious – spotting a region hosted in the cloud via Help About. Top: a region hosted at the Lab’s co-location facility (note the agni.lindenlab.com in the address). Bottom: and a region running on a simulator in the cloud, using an AWS address.

As per K.T. Kingsley’s comment below, scripters confused about obtaining host names via scripted means should refer to this forum thread.

In Brief

  • The Jejina region (old-style Linden Homes) has been reported as having “weird” EEP settings that are out of sync with the surrounding regions, and also has a odd Map tile. The exact cause is unknown. Anyone seeing similar oddities in Mainland EEP settings / Map tiles should contact support.
  • A large swath of Satori suffered significant issues with regions staying up during a 24-hour period over the weekend. Exact cause is unknown, but the issue now appears resolved.

2020 Simulator User Group week #40 summary

Swan, July 2020 – blog post

The following notes were taken from the September 29th Simulator User Group meeting – although there is not a lot in practical terms to report, the meeting largely given over to another music event.

Simulator Deployments

Please refer to the server deployment thread for news and updates. However, there are currently no planned deployments for week #40.

SL Viewer

The Love Me Render #4 RC  viewer, version 6.4.9.549455, containing only fixes for EEP issues was issues on September 24th, and promoted to release status on Monday, September 28th.

In addition, the previous iteration of the Lover Me Render viewer, version 6.4.8.547427, was withdrawn. This leaves the remaining official viewer pipelines as:

  • Release channel cohorts:
    • Mesh uploader RC viewer, version 6.4.8.548061, September 8.
  • 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 Performance

There have been a number of reports of region performance issues that appear to be coupled to simulator version 548903. These reportedly manifest as rubber banding when users walk around, viewer-based profiles being very slow to load, estate bans taking about 30 to 45 seconds to take effect, and experiences  not functioning correctly – such as repeatedly asking people who have already joined it to do so. Some have also reported HTTP communications issues. Restarting region apparently resolves these issues initially, but simulator performance starts to degrade once more.

It’s not clear if Jiras have been filed with specifics of the issue, but those Lindens at the meeting were interested in learning more. For my part, I had noticed an increase in the time taken to load viewer-based profiles of late, but as this has generally happened in “busy” regions, I’ve assumed it is the general load on resources, rather than indicative of a potential broader issue.

2020 Simulator User Group week #39 summary

Dim Sum Gardens, July 2020 – blog post

The following notes were taken from the September 22nd Simulator User Group meeting – although there is not a lot in practical terms to report.

Simulator Deployments

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

  • On Tuesday, September 22nd, the grid’s main SLS channel was updated to simulator maintenance release 548903, containing updates related to the cloud uplift work which contain no user-visible changes.
  • There are no RC deployments planned for the week.

SL Viewer

The Bormotukha Maintenance RC viewer, version 6.4.8.548890 dated September 18th, was promoted to de facto release status on Tuesday, September 22nd.

The rest of the official viewer pipelines remain as follows:

  • 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:
    • Mesh uploader RC viewer, version 6.4.8.548061, September 8.
    • Love Me Render RC viewer, version 6.4.8.547427, August 21.
  • 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.

Cloud Uplift

  • There is a known issue with Navmesh retrieval on cloud-hosted regions on Aditi.
  • The Lab believe they have a solution for the outward e-mail issue with cloud-based regions. However, due to the way in which Aditi regions are set-up, testing of the fix is being carried out elsewhere, but the hope is the fix will be usable once there are user-accessible regions on Agni that are running on AWS services.

In Brief

  • There is no update on the Group chat / IM failure issue (see BUG-229219).
  • The majority of the meeting focused on a general discussion on region crossings – notably with vehicles – and the assorted problems that can arise, including the inconsistencies in some things like object entry and group access are handled (the former can prevent vehicle and avatar entry, whereas the latter can allow a vehicle into a region / parcel, but then eject the driver / passenger, obviously resulting in problems).

2020 Simulator User Group week #38 summary

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.
