The key points of discussion are provided below with time stamps to the relevant points in the video, which will open in a separate tab when clicked.

This was another  short meeting.

SL Viewer

[0:34-3:12]

The Umeshu Maintenance RC viewer updated to version 6.2.4.529755 on Wednesday August 7th.

The remaining pipelines are as follows:

  • Current Release version 6.2.3.527758, formerly the Rainbow RC viewer dated June 5th, promoted June 18th – No Change.
  • Release channel cohorts:
  • Project viewers:
    • 360 Snapshot project viewer, version 6.2.4.529111, July 16th.
    • Legacy Profiles viewer, version 6.2.3.527749, June 5th. Covers the re-integration of Viewer Profiles.
  • Linux Spur viewer, version 5.0.9.329906, promoted to release status 29th November 2017 – offered pending a Linux version of the Alex Ivy viewer code.
  • Obsolete platform viewer, version 3.7.28.300847, May 8th, 2015 – provided for users on Windows XP and OS X versions below 10.7.

Viewer Promotions

The hope is that some of the current four RC will gain promotion to full release status in August, as the bug list on all of them is “really small”.

In Brief

Inventory Issues, Fixes and Log-in Changes

[3:34-10:50]

  • Some Firestorm users are reporting an uptick in inventory issue, such as corruptions. It appears that, while usually a last resort, clearing inventory cache may correct it if it occurs.
  • There is some work being carried out by the Lab that improves their ability to fix back-end inventory issues. This work is getting an “unusually thorough” QA pass, so may be a while before it is ready for support deployment.
  • Also, the Lab is working on a new log-in process that adds more checks to the inventory queries performed during log-in.
    • Currently, some of the queries, a necessary part of the log-in process, can be subject to database look-up failures that go unreported to the viewer, leading to inventory issues for the user.
    • The new process will ensure that if a query fails, an error message will be returned to the viewer, allowing it to request further look-ups. However, it will be a while before this enters production.
  • A reminder that large flat inventories (e.g. thousands of items on the same level) can cause the inventory queries to time-out and log-in to time-out. Should this happen, an inventory transform can be requested from support, which breaks large flat inventories down into a folder structure.

Second Life Engineering Jobs

[16:23-17:25]

  • The position for a Second Life Senior Graphics Engineer remains open.
  • A new position has opened for a software engineer (C++). Oz linden “would love” to recruit someone who has the relevant experience / background and who is a Second Life resident.
  • Applicants need to be US residents.

2019 SL User Groups 30/3: TPVD Meeting and Singularity

Summer Edge; Inara Pey, June 2019, on FlickrSummer Edge, June 2019 – blog post

The following notes are taken from the TPV Developer meeting held on Friday, July 26th, 2019. A video of the meeting is embedded below, my thanks as always to Pantera for recording and providing it. The key points of discussion are provided below with time stamps to the relevant points in the video, which will open in a separate tab when clicked.

This was a short meeting with text chat around animation systems and options – please refer to the video for details.

SL Viewer

[0:00-1:48]

There have been no changes through the week with regards to the viewer pipelines. With the SL Feature Summit in week #31, it likely means there will be no updates then, either.

  • Current Release version 6.2.3.527758, formerly the Rainbow RC viewer promoted June 18th – No Change.
  • Release channel cohorts:
  • Project viewers:
    • 360 Snapshot project viewer, version 6.2.4.529111, July 16th.
    • Legacy Profiles viewer, version 6.2.3.527749, June 5th. Covers the re-integration of Viewer Profiles.
  • Linux Spur viewer, version 5.0.9.329906, promoted to release status 29th November 2017 – offered pending a Linux version of the Alex Ivy viewer code.
  • Obsolete platform viewer, version 3.7.28.300847, May 8th, 2015 – provided for users on Windows XP and OS X versions below 10.7.

Both Love Me Render and Rakes On Mesh are considered as being “very close” to promotion. However, as noted in my notes from the Content Creation meeting, BOM is going to be going through a QA review at the Lab, so Love Me Render might be the nearer of the two in terms of suitability for promotion.

SL Feature Summit

[1:51-2:00]

As noted, there is a SL Feature Summit in week 31, so there will also be no simulator releases next week.

Other Topics

UDP Messaging – Further Deprecation

[22:29-23:48]  There are still “a couple” of inventory-related UDP operations that need to be deprecated. This will not be a short-term change, however, as the corresponding HTTP operations handling has yet to be written. Once they have been, the UDP operations will be removed from the official viewer. Time – measured in months – will be allowed for TPVs to adopt the HTTP before the UDP is deprecated on the back end.

In Brief

  • [3:10-5:50] Can we have more than two shadow casting projectors? Short answer: not without measuring performance impact. Long answer: no further rendering type changes are up for consideration until after Love Me Render, EEP and BOM have been released. See also STORM-2147.
  • [4:04-4:17] OS X and OpenGL deprecation: the lab is still investigating options for Mac support after Apple deprecates OpenGL support.
  • [9:38-10:45] BUG-227350 – a feature request to allow LSL scripted toggling of voice on / off, which could be useful for guest-moderate talks, etc., when a land owner isn’t present – has been accepted by the Lab for consideration, but with the caveat the potential for abuse may prevent it being implemented. However, it stands as a good example of how to submit a feature request.

Singularity News

[16:59-17:33] Singularity was one of the viewers affected by the majority of UDP asset messaging paths being deprecated and removed from the back-endcode recently. While there are Singularity nightly builds to overcome the issue, there has yet to be an official full release – although this is being worked on. Commenting at the TPVD meeting, Inusaito Kanya stated:

We’re nearing release very soon, the build directed to on our site right now is http://links.singularityviewer.org/?to=nightly because we really don’t want anyone getting the UDP assets. We have Linux ready mostly and we’re working on a couple last minute fixes here and there but otherwise we should be good. Mostly graphics fixes and last minute UI touches[ still to be done].

 

2019 SL User Groups 28/2: TPV Developer Meeting

Sweet Paradise; Inara Pey, June 2019, on FlickrSweet Paradise, June 2019blog post

The following notes are taken from the TPV Developer meeting held on Friday, July 12th, 2019. A video of the meeting is embedded below, my thanks as always to North for recording and providing it. The key points of discussion are provided below with time stamps to the relevant points in the video, which will open in a separate tab when clicked.

This was a short meeting with a lot of non-specific text chat. Please refer to the video for details.

SL Viewer

[1:19-3:20]

The Bakes on Mesh RC viewer updated to version 6.3.0.529185 on July 11th.

Viewer Pipelines

The remaining LL viewer list looks like:

  • Current Release version 6.2.3.527758, formerly the Rainbow RC viewer dated June 5, promoted June 18th – No Change.
  • Release channel cohorts:
  • Project viewers:
    • Legacy Profiles viewer, version 6.2.3.527749, released on June 5th. Covers the re-integration of Viewer Profiles.
  • Linux Spur viewer, version 5.0.9.329906, dated November 17th, 2017 and promoted to release status 29th November 2017 – offered pending a Linux version of the Alex Ivy viewer code.
  • Obsolete platform viewer, version 3.7.28.300847, May 8th, 2015 – provided for users on Windows XP and OS X versions below 10.7.

Anticipated Viewer Updates

  • A further iteration of the EEP RC viewer is with QA and should appear in week #29 (week commencing Monday, July 15th).
  • Bakes on Mesh is expected to go through at least one further RC iteration, although it is believed that all viewer-side required fixes have now been implemented.
  • The July 9th Love Me Render (rendering pipe improvements / fixes) update moved that viewer closer to being ready for possible promotion to release status.
  • The 360 Snapshot viewer has now been merged up to the current LL viewer release and is undergoing testing, so should be re-appearing as a project viewer soon.

Viewer Build Process

[18:23-20:54]

The update of the viewer build process using Visual Studio 2017 / the latest Xcode is still stuck on a required update (to boost::fibers), and will likely remain that way for another week or so.

Texture Fetching / Texturing Caching Project

[21:01-23:05]

The project to improve texture fetching and caching in the viewer, which has been on hold for some time, is expected to re-start very soon. This work will likely including experimenting with using the HTTP/2 library, rather than the current curl library; this is also the project that includes support for higher texture memory in the official viewer as well as large on-disk caches. All of which, it is hoped will result in a noticeable performance improvement.

Other Topics

  • [5:15-7:23] It’s been noted the final deprecation of asset UDP messaging may be affecting the session times for scripted agent drivers built over LibOpenMetaverse, and the Lab threw out a question to open-source devs as to whether they could provide further information.
  • [27:02-27:40] There are some improvements coming to search, but it is too soon to say exactly how these will be reflected in the viewer; currently the focus is on improving the search infrastructure.
  • [29:40-31:25] work is continuing on the re-introduction of the “legacy” Profile floater. However, there are web-side changes needed (e.g. the feed needs to be turned into an API end-point). There is no planned simulator changes for this change, so profiles won’t be capabilities-driven.

2019 SL User Groups 26/3: TPV Developer Meeting

Atonement; Inara Pey, May 2019, on FlickrAtonement, May 2019 – blog post

The following notes are taken from the TPV Developer meeting held on Friday, June 28th, 2019. A video of the meeting is embedded below, my thanks as always to North for recording and providing it. The key points of discussion are provided below with time stamps to the relevant points in the video, which will open in a separate tab when clicked.

There are assorted text chat discussions scattered throughout the video covering various topics (e.g. Firestorm code that exposed a viewer setting to show the physics shapes of mesh objects, general discussion of LL hiring, avatar dot colours on the map, and opinions on a “lite” version of the viewer (remember the Basic viewer?), the technicalities of multi-threading, etc). These are not necessarily referenced in the notes below – please refer to the video.

SL Viewer

[1:30-7:00]

Recent Updates

  • As noted in my Content Creation summary, the Bakes On Mesh viewer is once again available with version 6.3.0.528495. This includes:
    • A new inventory icon for the “universal” wearable type.
    • A fix for a serious security issue type of bug.
  • The Love Me Render RC updated on Wednesday, June 26th to version 6.2.4.528505.
  • The Umeshu RC viewer updated on Thursday, June 27th to version 6.2.4.528492.

All of these RC viewer should now have parity with the current release viewer.

Note: at the time of writing, these viewers only appear on the Alternate viewers page; they are not listed on the the index of available viewers.

Viewer Pipelines

The remaining LL viewer list looks like:

  • Current Release version 6.2.3.527758, formerly the Rainbow RC viewer dated June 5th, promoted June 18th.
  • Release channel cohorts:
  • Project viewers:
    • Legacy Profiles viewer, version 6.2.3.527749, dated June 5th. Covers the re-integration of Viewer Profiles.
  • Linux Spur viewer, version 5.0.9.329906, dated November 17th, 2017 and promoted to release status November 29th, 2017 – offered pending a Linux version of the Alex Ivy viewer code.
  • Obsolete platform viewer, version 3.7.28.300847, dated May 8th, 2015 – provided for users on Windows XP and OS X versions below 10.7.

Additional Viewer Notes

  • Currently the BOM and EEP viewers appear vying for promotion to de facto release status. A new EEP RC is anticipated in early week #27 (commencing Monday, July 1st). It is hoped that both viewers are now functionally ready for release, and that both will go through promotion to release status by the end of July. Of the two, the more likely for promotion first is BOM – but this is not an absolute.
    • [9:40] The potential closeness of BOM and EEP going to release status relative to one another may raise questions within some TPV groups as to how to best handle them (.e.g. individual release or a combined release with both).
  • It is hoped that other projects – notably the texture fetching / texture caching re-write project – can start to be carried forward once more, with project viewers surfacing as a result at some point.
  • If the texture fetching can be improved, the Lab might also look at inventory fetching, although the two are somewhat different. There is already some work going on with the inventory back-end, which could also lead to opportunities to work on the viewer side of inventory handling.
  • [10:55-11:50 and 46:00-47:25] The 360 Snapshot project viewer has been brought up to parity with the current release viewer, and is currently awaiting QA. It should hopefully be returning to the viewer list soon™, and work should resume on the 360 snapshot function itself in the near future.
  • [12:52-14:26] Apple OpenGL deprecation: the Lab is working on a strategy to deal with this, but it is “too soon” for detailed discussion, however, part of it is dependent on the Lab getting an additional graphics engineer hired to work on SL.

Viewer Build Process

An issue with the new viewer build process using Visual Studio 2017 / the latest Xcode has been identified and hopefully rectified. The process will therefore be going to QA. Providing all goes well, the build process will then be deployed to the viewer build farm.

Script Processing Issues

[26:14-26:50]

The simulator updates that will hopefully improve script run time issues (see  BUG-226851 and BUG-227099) mentioned in my Content Creation summary, are unlikely to be deployed until at least week #28 (week commencing Monday, July 8th).

Other Topics

  • [7:01-8:00 and 28:22-29:00] There will be no viewer releases at the end of week #27, nor will there be any simulator RC channel deploys on Wednesday, July 3rd, due to the July 4th break. Similarly, there will be a period at the end of July / start of August with no releases / updates, as the SL team will be having their summer planning summit.
  • {21:15-25:15] iOS companion app: work has started on trying to get the initial test versions through Apple’s test process. It’s not clear how long this will take.
    • As per my summary and audio of Oz and April Linden’s Meet the Lindens session, this will initially be a basic communications app, allowing users to chat to others (users won’t even have an in-world location, per se).
    • Obviously, it is planned to evolve the app over time.
    • It’s not clear if users in-world will be able to discern if a user is on the iOS client.
    • Once the test version is available, iPhone users will require TestFlight on their ‘phones to play with it (hopefully, it should also run on iPads as well, although there may be some configuration differences).
    • Some of the back-end infrastructure the Lab is building is support of the app might be applicable to use with a web application, but that is not on the current plans.
  • [26:53-27:50] The Lab believe they have identified one of the causes of performance collapse when avatars teleport into a region. This is being queued up to be worked on.
  • [28:00-28:18] The latest versions of simulator code changes to help with region crossing and teleport issues should be fully deployed across the grid following the SLS (Main) channel deployment in week #27.
  • [32:00-43:30 – chat] Problems have been reported with ASCII characters used in group names displayed by the avatar tag taking time to correctly display in busy regions, which are notably seen with the Firestorm viewer, but which are proving difficult to reproduce in the official viewer. See: BUG26338.
    • This topic kicked off a length chat discussion that rolled into avatar dot colours on the map, viewer updates for avatar tags, etc.
    • The chat further rolled into a discussion of “why no VR in SL?”. Short answer: performance isn’t consider good enough to deliver a really comfortable VR experience, although non-LL driven tests have continued.
  • Having trouble with texture loading? I could be your system, depending on its age, but it also might be your anti-virus software – try explicitly whitelisting your viewer cache in you AV software and see if that helps.

2019 SL User Groups 24/3: TPV Developer Meeting

aZiLe; Inara Pey, May 2019, on FlickraZiLe, May 2019 – blog post

The following notes are taken from the TPV Developer meeting held on Friday, June 14th, 2019. A video of the meeting is embedded below, my thanks as always to North for recording and providing it. The key points of discussion are provided below with time stamps to the relevant points in the video, which will open in a separate tab when clicked.

SL Viewer

[0:23-3:40]

There have been no further LL viewer updates wince the Love Me Render and Bakes On Mesh RC releases on June 10th. This leaves the current LL viewer pipelines as follows:

  • Current Release version 6.2.2.527338, formerly the Teranino RC viewer, promoted May 22 – No Change.
  • Release channel cohorts:
  • Project viewers:
    • Legacy Profiles viewer, version 6.2.3.527749, released on June 5th. Covers the re-integration of Viewer Profiles.
  • Linux Spur viewer, version 5.0.9.329906, dated November 17th, 2017 and promoted to release status 29th November 2017 – offered pending a Linux version of the Alex Ivy viewer code.
  • Obsolete platform viewer, version 3.7.28.300847, May 8th, 2015 – provided for users on Windows XP and OS X versions below 10.7.

BOM Alpha / Universal Wearable Issues

Please also see my week #24 CCUG update for details of issues around alpha handling and the universal wearable channels in the Bakes on Mesh viewer. Vir indicated that the Lab has a handle on this, which will require an Appearance Service update and a “small” viewer-side update that will include a new inventory icon for universal wearables.

Legacy Profile Project Viewer

[3:50-6:10]

  • As per my preview article, the Legacy Profiles project viewer (version 6.2.3.527749 at the time of writing), moves avatar profile in the viewer back into their own floater, rather than using a view of the web profile.
  • This work is in its initial stages, and the overall aim of the work is in flux. This means that the profile panel itself might be subject to further revision, and that even the web feed itself might gain its own floater, rather than being a tab within the new profile floater.

360 Snapshot Viewer

[6:15-7:33] Note that the 360 Snapshot viewer has been temporarily withdrawn, due to  the core viewer code being badly out-of-date. The viewer is currently in the process of being updated – no functionality changes to the 360 snapshot capability, purely an update to bring the core code up-to-date with the current release viewer. It is hoped this will reach the Lab’s QA team soon, and reappear as a project viewer in due course.

Group Chat Performance

[17:01-34:15]

  • A frequent complaint with Group chat is that it can be slow.
  • The Lab’s investigation in issues shows that actual chat messages and group notices account for the minority of traffic seen in the group chat system.
  • By far the largest volume of traffic is purely the on-line / off-line notifications that are being sent.
    • So, for example, in a group of 20,000 members, each time someone logs-in or out of SL, 20,000 messages are generated in the group chat system; for a 50,000 member group, the number is 50,000, and so on.
    • Note that a couple of years ago, to try to improve things, the Lab disabled the ability to see the group members list for groups over 5,000 members – but the actual messages themselves are still circulated.
  • The Lab is therefore seeking feedback on how big an impact it would be if these on-line / off-line messages were turned off on the simulator side, either just for very large groups (upper limit TBD), or simply for all groups, in the hope it will reduce the volume of traffic and help improve overall chat performance.
  • It has been acknowledged that if this is to be done, it would be useful for group members to still be able to see which group owners / moderators are on-line, and for group owners / moderators to see which group members are on-line, so that issues / enquiries can be dealt with. The Lab will investigate whether this can be done.
  • Note that removing these messages would not affect the “last login” date for the group members list.
  • It is likely the Lab may carry out some experiments on a small cohort of groups to see what might be done and check for any measurable performance increase in those groups.
    • Some experimenting has already been done in trying to batch the on-line / off-line update messages, but it’s not clear if this has had any positive impact where it has been done.
  • An alternative suggestion is to break groups into types: e.g. those purely for chat (which may require more information on users’ on-line status) and those just for outwards announcements.
    • This is already done to some degree by group owners setting group rules / members’ capabilities; however, it still means the on-line / off-line messages are still sent.
    • Were the Lab to try to implement a more robust system like this, there would be a major issue is handling existing groups and determining how to define them.
  • [41:00-41:15] More generally with group chat, the Lab have considered adding an ability to add a server-side block (accessible through the viewer) on chat from groups a user does not wish to hear from, chat-wise. This may be implemented “at some point”.

In Brief

  • [36:10-36:35] Avatar Teleport on Region Performance: as we know, avatars arriving in a region can have a significant impact on the region’s performance. The Lab believe that have a partial understanding of the problem, and has some ideas on how the impact might be lessened.
  • [44:20-46:44] BUG-225696 – “All offline inventory offers from scripted objects are lost” –  was believed to have been fixed in the Teranino RC viewer, however it still appears to be occurring. As such BUG-227179 has been raised against the issue, and the Lab will look into it again.
  • [52:16-53:30] Kitty Barnett (Catznip) has been working on trying to clean-up a series of viewer-side events that can cause the viewer to stall after the login.cgi process has completed that can cause region messages (including IMs) to be lost. The Lab is aware of these as well, but would be interested in accepting Kitty’s code contributions if she can get them finished.
  • The Lab is still looking for a Senior Graphics Engineer to work on Second Life (San Francisco based).

Total Aside

In discussing SL groups (and as a point of humour), Oz and Grumpity revealed the first three Jira items filed internally at the Lab:

  • SL-1: Second Life should grow to dominate the entire world, thereby making us the de facto world leaders.
  • SL-2: Build a time machine.
  • SL-3: Build an army of robot cats.

SL-2 was seen as necessary because the Lab knew that it would eventually need to go back and re-engineer some of the decisions made when first defining / building Second Life and its architecture. Sadly, and DeLorean cars notwithstanding, there are still considerable blockers that prevent its implementation!

2019 SL User Groups 22/3: TPV Developer Meeting

(Fae Forest), Elvenshire; Inara Pey, April 2019, on Flickr(Fae Forest), Elvenshireblog post

The following notes are taken from the TPV Developer meeting held on Friday, May 31st, 2019. A video of the meeting is embedded below, my thanks as always to North for recording and providing it. The key points of discussion are provided below with time stamps to the relevant points in the video, which will open in a separate tab when clicked.

Note this meeting involved a lot of text-based chat on VRAM, script limits, and avatar complexity which, in the interest of brevity with these notes, I leave to the video.

SL Viewer

[01:18-2:22]

The Rainbow Maintenance viewer – version 6.2.3.527584 – was released on  Wednesday, May 29th. This viewer specifically fixes a known Windows / Nvidia issue where on exiting Second Life, the system video is distorted – see BUG-226803.

Note that at the time of writing this summary, the Rainbow RC viewer is not listed on the new Alternate Viewer page; if you are experiencing this particular issue, and wish to try the new RC, please go to the main Viewer Release page, where it *is* listed.

There should be a project viewer forthcoming “soon” with a number of open-source contributions

The remaining LL viewer pipelines are unchanged, as follows:

  • Current Release version 6.2.2.527338, formerly the Teranino RC viewer, promoted May 22 – NEW.
  • Release channel cohorts (please see my notes on manually installing RC viewer versions if you wish to install any release candidate(s) yourself):
  • 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.

As per my CCUG summary, it is anticipated updated versions of EEP and Bakes on Mesh RC viewers should be appearing in week #23 (commencing Monday, June 3rd, 2019).

Official Linux Viewer

[5:47-7:05]

  • The Lab has received a comprehensive open-source Debian-based contribution for Linux.
  • This will have restricted functionality (e.g. no Voice, as Vivox who supply the Voice EXE for the viewer no longer support Linux).
  • The Lab is currently putting time into trying to build this Linux option within their existing viewer build. If this succeeds, they will likely issue the viewer (I’m guessing as a project viewer initially).

Group Notices to IM

[10:50-12:00]

  • As per my April 26th TPVD meeting notes, the Lab is considering the possibility of no longer sending group notices to e-mail when a user is off-line.
  • This will only be for off-line group notices. It will not block / change the receipt off-line IMs.
  • The reason for making the change is to help is secondlife.com being regarded as a spam domain by e-mail services.
  • Work has not yet commenced on this.
  • The Lab expects to be doing “significant” work on groups in general “pretty soon”. This will include work on group notice delivery reliability, general group chat lag, etc.

In Brief

  • [2:24-3:28, 13:49-14:10, and 17:20-19:15] Teleport improvements:
    • Work continues in trying to stabilise / improve teleports to avoid any repeat of recent problems.
    • Work is also in progress to improve how attachments are handled on teleports to lessen instances of attachment loss, ghosting, etc.
      • Some of these issues might be related to viewer changes, and the Lab is currently testing fixes and experimenting with the viewer, and the latter may result in some tweaks to the way the viewer handles attachments.
      • More on this to follow once the internal tests are complete and have been assessed.
      • As it is, improvement have been deployed to help prevent attachments getting killed on teleports, although further work on this may still be required.
  • [7:05-10:08] Mobile client:
    • LL continue to work on the iOS mobile client for Second Life.
    • iOS was selected because “at the time the decision was taken, there wasn’t anything for iPhone”, and the Lab didn’t have the resources available to handle both iOS and Android development.
    • More details on the iOS client’s functionality are hoped to be available “before too long”.
    • Android remains a hoped-for goal, although there is no time line for when it might happen.
  • [12:10-12:30] Last names: work is continuing on the return of last names, although deploying the capability is not imminent.
  • [12:57-13:30 and 14:33-16:15] Transitioning SL to the cloud:
    • Again, work is progressing, and some services have been transitioned (note: not any user-accessible simulators), without any impact being noted / felt by users.
    • More services will be transitioning in the next few months.
