The following notes were taken at the Simulator User Group meeting held on Tuesday, February 18th.

Simulator Deployments

As always, please refer to the week’s deployment thread for updates.

• The SLS (main) channel servers were updated with simulator update 2020-02-05T22:16:31.536040, providing support for the upcoming Name Changes feature.
• At the time of writing, the deployment thread indicates there is no RC deployment scheduled for Wednesday, February 19th, however according to Simon Linden speaking at the SUG meeting, there will be an RC update. so again, check the deployment thread for updates.

SL Viewer

At the time of writing, the official viewer pipelines remain unchanged from the end of week #7:

• Current Release version 6.3.6.535003, formerly the Xanté Maintenance RC, dated January 22, promoted January 27 – 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):
  • EEP RC viewer updated to version 6.4.0.536347, February 11.
  • Love Me Render RC viewer, version 6.3.7.536179, February 10.
  • Yorsh Maintenance RC viewer, version 6.3.7.535996, February 7.
  • Camera Presets RC viewer, version 6.3.6.535138, January 24.
• Project viewers:
  • 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.

Brief Notes

• Script running: concerns continue to be expressed over recent changes to script behaviour designed to improve script performance within a region may be affecting the ability of scripts to run in a timely fashion when their object is rezzed. Up to a 2-second delay has been observed, although this is by no means constant for any given object. This is a known issue with the Lab, who are continuing to work to improve the situation.

The following notes were taken at the Simulator User Group meeting held on Tuesday, February 11th.

• Work is continuing to try to clear the last blockers staying in the way on the Name Changes deployment.
• BUG-228162 “Issue with experience_permissions_denied() and XP_ERROR_NOT_PERMITTED triggered when experience permissions are granted by more than one person” – appears to report an issue in granting permissions if dialogue requests are simultaneously open.

The following notes were taken at the Simulator User Group meeting held on Tuesday, February 4th.

Simulator Deployments

As always, please refer to the week’s deployment thread for updates.

• A single RC channel deployment is planned for Wednesday, February 5th. Server update 2020-01-30T23:51:10.535702 should comprise support for the upcoming Name Changes capability.
• All other channels and simulators should remain on server update 2019-12-04T20:29:26.533447.

Linden Lab is considering dropping the date / time stamp from simulator update references, and just leaving the version number (the last 6 digits of the reference – so 535702 and 533447 in the releases above).

SL Viewer

On Tuesday, February 4th:

• The Yorsh Maintenance RC viewer, version 6.3.7.535600 was issued.

At the time of writing, all remaining viewer pipelines remain as follows:

• Release viewer,version 6.3.6.535003, formerly the Xanté Maintenance RC, dated January 22, promoted January 27
• Release channel cohorts:
  • Camera Presets RC viewer, version 6.3.6.535138, January 24.

Brief Notes

• Rider Linden is working on trying to improve avatar and vehicle region crossings by reducing some of the overheads involved.
• It has been pointed out that with the on-going work in transitioning Second Life to the cloud, parsing http-in urls is not a good idea.
• Simulator host names are still liable to include “agni” and “aditi” following the cloud transition, but they will not be at “lindenlab.com”.

Not a lot to report; much of the conversation was around general ideas for improving aspects of SL scripting (e.g. script-to-script communications) and speculations about the migration of SL to AWS.

Simulator Deployments

As always, please refer to the week’s deployment thread for updates.

• There were no deployments to the main SLS channel on Tuesday, January 28th, although there are reports some regions were restarted.
• An RC deployment is planned for all simulators on the RC channels for Wednesday, January 29th. Server update 2020-01-23T00:43:42.535128 is specifically aimed at making “rolling the grid more gentle on our non-simulator servers”. According to Simon Linden, speaking at the meeting:
  • These updates shouldn’t be user-visible, but should help improve the issue of starting scripts following a simulator re-start.
  • They *might* result in improvements on region crossing between regions on the RC channels, but this is by no means certain.

SL Viewer

The Xanté Maintenance RC viewer, version6.3.6.535003 and dated January 22nd, was promoted to de facto release status on January 27th.

At the time of writing, all remaining viewer pipelines remain as follows:

• An RC deployment is planned for Wednesday, January 22nd, but no details were available at the time of writing.

Simulator Issues

• Some region holders are still reporting script runtime issues. There may be some work in the RC deployment to help with these issues, but again, this wasn’t clear at the SUG meeting, due to the lack of release notes.
• There is some work to help manage scripted attachments and vehicles during region crossings, but no specifics given.
• There have been reports of object_rez() events randomly failing. It’s not clear how widespread the issue is, but it is a known issue with the Lab, but a reliable reproduction of the problem has yet to be reported / found.

SL Viewer

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

• Current Release version 6.3.5.533275, formerly the Wassail RC viewer, dated December 4, promoted December 12. – No change.

Simulator Deployments

There are no server deployments planned for week #3 due to the next batch of updates being ready for deployment.

Simulator Issues

• There are still reports of recent simulator updates causing issues for certain types of breedables. The Lab is aware of these problems, and while fixes are in the works, they may not be in the next set of simulator updates.
• LL has continued a post-mortem into the region restart issues from week #2, with Simon Linden noting they have hopefully learned enough such that future restarts such run a lot better (and hopefully more smoothly!).
• “A couple of hosts” that were not handling teleports as expected at the end of week #2, which should have been corrected.
• Additional data that the Lab has been gathering on simulator performance does show that long-running simulators incur increased host resource utilisation, but for reasons yet to be identified.
  • Scripted avatar loads might in part be responsible, depending on what their scripts are doing, but LL would prefer to gather further data rather than speculate on possible causes.
  • However, there are regions where issues have been recorded, but which do not have large avatars loads.
  • LL have tried multiple approaches to making similar slow-downs occur on the beta grid (Aditi), but the problem doesn’t appear to occur “on demand”, making possible causes harder to identify.

In Brief

• Rider Linden is looking at region crossings, and hopes to have some code that should help improve things when it is ready for deployment. However, he notes that the improvements will be “nowhere near what I would ultimately like.
