2022 Land & Concierge meetings – week 4

The Concierge and Land User Group meeting area

The Concierge & Land user group meeting is generally held on the 4th Wednesday of the month “intended for discussion & education of SL topics such as current known issues and bugs, project viewers and new features, and general Mainland issues.” Attending the Wednesday, 26th January, 2022 meeting from the Lab were Wendi, Izzy and Vix Linden.

Please note, this is a summary, not a full transcript – so only those topics related to SL services, etc., managed / provided by the Lab on which there is general discussion and feedback from the Lab staff at the meeting are recorded below. For general audience comments, non-LL topics (such as TPVs) please refer to the video by Pantera embedded at the end of this article, and my thanks to her as always for recording the meetings.

2021 Review of the Year

[Video: 2:55-6:12]

Vix Linden raised the Lab’s December 2021 blog post looking back at 2021 and ahead to 2022.

  • Highlighted the upcoming new features – avatar expressiveness, Premium Plus, Mobile solution new user avatar customisation, script improvements, etc.
  • Noted that there are no ETAs for any of the work (although improvements in scripts running on simulators has been an improvement due to the recent tool update), as it is all either in progress or in the planning stages.
  • Pointed to the fact that with the Uplift transitional work completed, 2021 allows LL to focus on bedding-in services on AWS and starting to offer performance improvements.

High Fidelity Spatial Audio and Vivox

[Video: 6:34-8:52]

  • Following the announcement that High Fidelity Inc, has invested in Linden Research (money, skills sets and patents) there was speculation  – emphasis intentional, as some of it has been on this blog – that High Fidelity’s spatial audio might at some future point be integrated into Second Life.
  • In response to questions on this, the general feedback from the Lindens at the meeting was that this currently isn’t being planned or discussion in-house, and that as such, voice will remain on Vivox for at least the foreseeable future.

Simulator Updates

[Video: 20:44-23:03]

  • Vix re-iterated that the script performance improvements currently being seen is part of an overall “re-tooling” project that has been underway for some time that has involved changes to the hardware configurations used by the simhost servers and changes to the simulator code to better leverage the AWS servers and their supporting infrastructure.
  • In short: lower script time in the simulator stats (CTRL-SHIFT-1) – so 5ms instead of 15ms = script run improvements.
  • As noted via the official blog post on the subject and via my weekly Simulator User Group summaries, this change should manifest in better script run times and improved overall performance within a region.
  • A cautionary note with this is that with these improvements may come increased throttling elsewhere within the code (e.g. such as with, but not limited to, remote services accessed via llHTTPRequest), or where regions were already until a heavy script load.
  • Also referenced the deprecation of various older protocols (e.g. 1.0 and TLS 1.1, libopenmetaverse).

In Brief

  • [11:52-12:33] The research questionnaire referenced in this official blog post were mentioned, and the fact that the e-mails containing it (for those who receive them) will be coming from  research@secondlife.com, which is a legitimate Lab e-mail address. It was also stressed that the Lab will never request user divulge things like account passwords within this type of e-mail contact.
  • [16:22-16:50] Mention is made of the Tilia Inc., / Unity partnership announced on Wednesday, January 26th that will see Unity make Tilia’s services available to their community of developers – see the official press release and my own blog post for more.
  • [17:50-20:00] background was given to the Lab’s approach to employing outside of the United States, having offices elsewhere in the world, etc. The comments were predicated on some noting that Tilia Inc., (a wholly-owned subsidiary of Linden Research) has / has had a registered office in the UK since 2017. This segued into a discussion of LL providing 24/7 coverage by staff and the cost of doing so.
  • [31:07-32:10] A re-iteration to the changes made of off-line e-mail notification preferences (also see: Lab announces change to e-mail preferences for Group notices), and which came into effect from December 15th, 2021 – with a note that future options to control receipt of certain notifications via e-mail might be added at some point in the future.
    • There have been some reports that altering the settings can prevent the receipt of all off-line notifications via e-mail – which may well be confusion over setting the check boxes;  a request was made for people to double-check their settings (links in both blog posts above) if they are encountering problems in receiving off-line notifications.
  • [35:19-36:30] A reminder that the Valentines Shop and Hop event is on the horizon (Wednesday, February 2nd through Tuesday, February 15th, 2022), and that there will likely be the usual Valentines themed Last Names, the Hug a Linden, etc., activities, and so on.
  • [37:52-42:05] There are currently no known plans to extended the region / parcel ban list to support large numbers of names – those feeling it needs to be extended are asked to file a feature request jira.
    • Izzy Linden also indicated he has submitted an internal request to have listed automatically updated on the basis of account status (e.g. for accounts flagged as Closed are automatically removed from ban lists).
    • Izzy also warned about the “airlock” issue (as Izzy calls it) that could accidentally exclude people from region / parcel access (wherein there are allow / ban lists at both the region level and the parcel level, both of which have to be checked, but before the check is complete, users on slower connections time-out on their attempt to reach the region / parcel and so cannot reach it).
  • [54:50-56:40] In response to a question on the general mood at the Lab in the wake of recent changes / announcement, all they Lindens at the meeting indicated that they are personally “very charged” (positive) towards the direction in which SL is moving (including the move to AWS and what is being planned / implemented).

2022 SUG meetings week #4: Restart issues +Andrew Linden returns

Hanging Gardens of Babylon, January 2022 – blog post

The following summary notes were taken from the Tuesday, January 18th, 2022 Simulator User Group (SUG) meeting. The meeting was recorded by Pantera Północy, and the video is embedded at the end of this summary. Note this summary focuses on the key points of the meeting; where there is something to report, the video should be referred to should full details of the meeting need to be reviewed.

Server Deployments – Main SLS Channel Restart Issue

Despite being updated in week #3 with simulator version – 567269  – and with no RC update available for deployment, the SLS Main channel simhosts went through a restart on Tuesday, January 25th – and ran into a problem, with many regions remaining down for far longer than expected.

  • No detailed explanation for the issue has been given as yet other than, “one of our internal systems got a bit confused about what was started and what needed to be started.”
  • However, the issue was not in any way related to the simulator version itself, so no danger of the improvements it contains being rolled back.
  • Wulf Linden noted that the situation has provided LL with a lot of data that will hopefully allow them to “smooth out the pavement for the future.”

At the time of writing, any deployment to the RC channels for Wednesday, January, 26th was still TBA. Check the Second Life Server section of the forums for any possible announcement.

Available Viewers

This list reflects those official viewers available.

  • Release viewer: version version 6.5.2.567427 – Mac Voice hotfix viewer, January 13 – 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).
    • Maintenance RC viewer, version  6.5.3.567451 issued on January 20th, combining the Jenever and Koaliang Maintenance viewers.
    • The Tracy Integration RC viewer version 6.4.23.563771 (dated Friday, November 5) issued Tuesday, November 9.
  • Project viewers:
    • Mesh Optimizer project viewer, version 6.5.2.566858, dated January 5, issued after January 10.
    • Performance Improvements project viewer version 6.5.2.566967, dated December 17.
    • Performance Floater project viewer, version 6.4.23.562625, issued September 2.
    • Legacy Profiles viewer, version 6.4.11.550519, dated October 26, 2020.
    • Copy / Paste viewer, version 6.3.5.533365, dated December 9, 2019.

The Return of Andrew (Leviathan) Linden

The first person Philip Rosedale hired when establishing Linden Research (aka Linden Lab) was one Andrew Meadows. As Andrew Linden, he was pretty much the lead engineer for the server side of things, hosting what was the Tuesday Server and Scripting Meeting, (alongside Simon Linden) which later became the Simulator User Group Meeting. Andrew departed Linden Lab at the end of 2013 to join Rosedale at his (then) new venture, High Fidelity Inc.

Following news that High Fidelity had invested in Linden Lab (in what is increasingly looking like an informal merger) and that around seven High Fidelity staff were moving to work on Second Life, I pondered whether Andrew might be among them – and even publicly mused if indeed he would be in a later post on that subject.

Well, turns out he has, but under a new Linden name, that of Leviathan Linden. Appearing at the Simulator User Group Meeting on Tuesday, January 25th as Leviathan, Andrew has some trying to guess (good naturedly) at the reason for the name change – including having forgotten his old password! However, the explanation was simple, as he indicated whilst also noting the areas he’ll initially be working on.

Leviathan was the name I wish I had picked years ago. It seemed like a good pick for a new beginning. I’ll be working on simulator stuff. I’m getting back on my feet by fixing bugs and implementing small features.

Leviathan Linden (formerly known as Andrew Linden)

His appearance at the SUG meeting was positively received, as was the news he’ll once again be working on simulator-related projects. Which just leaves me room to say, “welcome back, Leviathan!”

In Brief

  • Following the reports of teleport disconnects / general region crossing issues, a further Jira has been filed noting recent events – BUG-231683 – in keeping with the request made at the last meeting, and this is now being investigated by members of the QA team.
    • Monty additionally noted other reports on crossings have also been filed and he is digging through them and the associated server-side logs.
  • User testing around BUG-231582 ” [Simplified Cache] Newly rezzed objects are invisible after relog under certain circumstances” suggests the issue is not cache related, but might be related to the Interest List, with it being noted the problem may have surfaced around the time back-end changes were made to the Interest List in preparation for the 360-degree viewer.
  • A question was asked on whether the tools update would impact anything with Key Frame Motion (KFM) behaviour on animations, with it being noted – anecdotally at this point in time – that the moving_end event seems to happen while the animation is still underway. None at the Lab appear to be aware as to why the updated server code should impact animation events, and a bug report has been requested if the issue is found to be reproducible.
  • The latter part of the meeting delving into a discussion involving a future implementation of HTTP/2, updates to libcurl, etc., and issues around them. Again, rather than me mangling things – please refer to the text in the video.

2022 TPV Developer meeting summary, week #3

Lost Dreams, January 2022 – blog post

The following notes are taken from the TPV Developer meeting held on Friday, January 21st, 2022.

These meetings are generally held every other week.  They are recorded by Pantera Północy, and her video of the meeting is embedded at the end of this report – my thanks to her for allowing me to do so – and it is used with the chat log from the meeting and my own audio recording to produce this summary, which focuses on the core topics discussed.

SL Viewer

[Video: 0:10-7:37]

  • The two Maintenance RC viewers Jenever and Koaliang, have been combined into a single Maintenance RC viewer, version 6.5.3.567451, issued on January 20th.

Important note: the above viewer version has a significant issue that may prevent users on this cohort from logging in. See this report for details. The recommendation is for those wishing to avoid the issue is to download and install the current release viewer (or if experiencing issues, to contact Support and request and inventory fix). 

The rest of the current list of official viewers remains as:

  • Release viewer: version version 6.5.2.567427 – Mac Voice hotfix viewer, January 13.
  • Release channel cohorts (please see my notes on manually installing RC viewer versions if you wish to install any release candidate(s) yourself).
    • The Tracy Integration RC viewer version 6.4.23.563771 (dated Friday, November 5) issued Tuesday, November 9.
  • Project viewers:
    • Mesh Optimizer project viewer, version 6.5.2.566858, dated January 5, issued after January 10.
    • Performance Improvements project viewer version 6.5.2.566967, dated December 17.
    • Performance Floater project viewer, version 6.4.23.562625, issued September 2.
    • Legacy Profiles viewer, version 6.4.11.550519, dated October 26, 2020.
    • Copy / Paste viewer, version 6.3.5.533365, dated December 9, 2019.

General Viewer Notes

  • The combined Maintenance RC viewer is likely the next viewer in line for promotion.
  • The Graphics improvements viewer still has some bug to be fixed prior to moving to RC status. In particular, Euclid Linden is working on fixing the frame stall issue resulting from a media texture update. Essentially, if vsync is enabled, then command buffer resources aren’t as unbounded as they are with vsync disabled, resulting in textures copied to it a call to update media textures exhausts all available resources, effectively blocking it until it is flushed, rather than the buffer simply being discarded as is with case with vsync disabled.

Upcoming Feature Work

[Video: 1:30-1:51]

  • Vir re-iterated that 2022 should see the viewer progress with new graphics features.
  • Further performance improvements beyond those currently within the Performance Improvements viewer are in the planning stages.
  • However, nothing is available for open discussion by LL at this point in time.

Animation Override Discussion

[Video: 11:07-52:00]

  • A discussion on improving avatar animations through the use of a cap / reliable messaging between the viewer and the server to directly replace the default server-side avatar animations (walk, run, sit, swim, fly, etc), with custom animations  – as per a scripted Animation Override – but avoiding the need  to use llSetAnimationOverride and scripted HUDs (as is currently the case).
  • See also  BUG-230100.
  • No work is currently planned for this, but interest was expressed in how it might work.
  • Firestorm has such a capability (adopted by some other TPVs), but the implementation isn’t widely favoured.
  • Another suggested option would be to make animations assets that define an animation set (e.g. a “Stand” asset that can be a container for a set of animation stands + the timing for running them + defining if they should be randomly or sequentially played).
  • A further advantage is that as well as removing the need for scripted attachments, it would allow everything to be drive via a viewer UI element, offloading work from the server to the Viewer (and potentially into an off-thread).
  • A problem in using a cap is that the viewer could hit it fairly readily, particularly if cycling through a large set of animated stands, for example.
  • There are also edge cases were scripts may still be required, but these are not inimical to the development of a client-side AO system able to work directly with the server-side animation graph.
  • The discussion lays out the benefits for more of a client-side AO control capability, and I refer you to it for the in-text comment – not that towards the end of the discussion, things turned towards some WIBNIs (as in, “Wouldn’t It Be Nice If the system could dynamically adjust walk speed to avatar size”), although elements like this would require a much more intensive overhaul of the animation system.
  • Please refer to the video for the full text of the discussion.

In Brief

  • [52:32-End] A short discussion on the benefits of LL defining an Area Search.
    • While Firestorm has an Area Search, it tends tow spam an entire region with requests for each individual prim hover properties (and is subject to draw distance and interest list).
    • ObjectNavMeshProperties, however (with changes and a throttle), could provide an alternative and potentially more preferable solution.
    • The core of this discussion is in text, with little input from LL – please refer to the video.
  • It has been reported via the forums that there is Mac OS Monterey performance issue associated with the viewer. At the time of writing, it is not clear how widespread this is or if a bug report has been raised, although the issue appears to be with a Monterrey OS capability, rather than the viewer – please read the forum post for more.

2022 SUG meetings week #3 summary

WQNC, January 2022 – blog post

The following notes were taken from the Tuesday, January 18th, 2022 Simulator User Group (SUG) meeting. The meeting was recorded by Pantera Północy, and the video is embedded at the end of this summary. Note this summary focuses on the key points of the meeting; where there is something to report, the video should be referred to should full details of the meeting need to be reviewed.

Server Deployments

Please refer to the server deployment thread for the latest updates and information.

  • Tuesday, January 18th saw the SLS Main channel updated to server release 567269, comprising a tools update previously deployed to the RC channels.
  • There is no planned deployment for the RC channels set for Wednesday, January 19th, and they will remain on server release
  • 567269.

In terms of the improvements wrought by the simulator updates, LL states that they have seen a considerable performance increase especially with respect to the number of scripts executed per frame, while Monty Linden added:

I’ve written up some release notes. Relevant points:
  • More script code executing may engage more throttles and drive external http services harder than previously.
  • SSL library updates move http-in/out away from sslv3, tls1.0, tls1.1.
  • This release does move the sims story forward a bit. We have seen http-out targets (llHTTPRequest) that only talk sslv3/tls1.0, for example.
  • Login is unchanged. Web properties have their own story.
In theory, some day, we’ll line up all our ingress and egress points and actually be able to tell you what’s going on there.

Available Viewers

This list reflects those viewers available via the first four links in the LL Viewer Resources section, below.

  • Release viewer: version version 6.5.2.567427 – Mac Voice hotfix viewer, January 13 – NEW.
  • Release channel cohorts (please see my notes on manually installing RC viewer versions if you wish to install any release candidate(s) yourself).
    • The Jenever Maintenance RC viewer, version 6.5.2.566860, issued on December 17.
    • The Koaliang Maintenance 2 RC viewer, version 6.5.2.566879, issued on December 17.
    • The Tracy Integration RC viewer version 6.4.23.563771 (dated Friday, November 5) issued Tuesday, November 9.
  • Project viewers:
    • Mesh Optimizer project viewer, version 6.5.2.566858, dated January 5, issued after January 10.
    • Performance Improvements project viewer version 6.5.2.566967, dated December 17.
    • Performance Floater project viewer, version 6.4.23.562625, issued September 2.
    • Legacy Profiles viewer, version 6.4.11.550519, dated October 26, 2020.
    • Copy / Paste viewer, version 6.3.5.533365, dated December 9, 2019.

In Brief

  • Some are seeing an uptick in disconnects during teleports, prompting an extended discussion (full context in in the video, interwoven with a discussion on pivot points arising from the previous CCUG meeting).  In short:
    • Frustration has been voiced that Jiras have been raised in the past on specific TP issues and “nothing was fixed”.
    • Regardless, LL are still requesting reports with information – who, from, to, exact time – of teleports that fail in a specific way, filed in a timely manner so that the relevant server files can be reviewed for possible clues / causes.
    • It is the specific nature of the failures that is of particular interest to LL, with more than one user reporting them, as Monty Linden noted, also replying to the critique that because “Lindens are in California” (only partially true) “with tiny ping times”:
I want a handful of user events that match their idea of a *specific* type of TP failure and the data so that I can go trawling for insight. As for ping times, this absolutely does colour how lindens understanding networking issues. But I’m in Boston so have poor ping times as well. All TP/region crossing failures are not the same. I want to filter down on a single type – not the rainbow of failures I already know are present.
    • Logs attached to Jiras for these cases do not necessarily need be be captured using the official viewer.
  • The issue of Friends lists failing to load (see BUG-231680) should be improved / resolved following a (non-simulator) deploy due on Tuesday, January 18th.
  • There has been a noticeable uptick of avatars taking longer to rez / remaining as clouds over the last couple of weeks or so. Some have mistakenly seen this as a simulator issue – although assets come via the CDN. Jiras have been raised on this, and the Lab is looking into matters.
