2019 SL User Groups 15/3: TPV Developer Meeting

Green Acres; Inara Pey, March 2019, on FlickrGreen Acres blog post

The following notes are taken from the TPV Developer meeting held on Friday, April 12th, 2019. A video of the meeting is embedded below, my thanks as always to North for recording and providing it. This was a relatively short meeting, with several periods of audio silence and text chat. The key points of discussion are provided below.

SL Viewer

  • The Estate Access Management (EAM) RC viewer updated to version 6.2.0.526190 on Friday, April 12th, 2019.
  • As noted in my CCUG summary, the EEP viewer updated to version 6.2.0.526104 on Thursday, April 11th.

All other viewer in the pipelines remain as:

  • Current Release version 6.1.1.525446, formerly the Love Me Render RC viewer, dated March 26, promoted April 2 NEW.
  • Release channel cohorts:
    • Bakes on Mesh RC viewer, version 6.1.1.525409, March 26.
    • Teranino Maintenance RC viewer version 6.1.1.525401, March 20.
  • 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. This viewer will remain available for as long as reasonable, but will not be updated with new features or bug fixes.

With the necessary back-end updates now made, it looks likely that the EAM RC viewer will be the next viewer to be promoted to de facto release status.

Teleport Issues

Teleport Disconnects

  • The Lab continues to try to understand the root cause(s) of the teleport disconnects. So far, they can only confirm it is not specific to any single viewer.
  • As previously indicated in my updates, the root cause of the issue is a race condition / timing issue – something that could be exacerbated by the distance of a user from the Lab’s servers (the grater the distance = the more time required for communications = the greater the chance of a timing issue / race condition).
  • Similarly, a high packet loss between viewer and simulator(s) might increase the chances of a disconnect occurring.
  • The problem remains in trying to identify precisely what has changed to cause any race condition / timing issue.
  • As noted in this week’s SUG meeting summary, there was a server RC deployment on Wednesday, April 10th – version 19#19.04.09.526122,. This included additional logging to help capture further data on the teleport disconnects, particularly capturing where the region handshaking may be failing.
  • Multiple regions have been replicated on Aditi, and having further enhanced logging enabled on them. This additional logging capability may be deployed to Agni in week #16, but not necessarily enabled, due to the performance impact it will have. However, the code will be in place should it be required.

Attachment Loss on Teleport

  • The Lab now has a “solid” repro for this issue. As anticipated, much of the problem appears to be related to having too many scripted attachments stacked on the same attachment point (e.g. the right hand, the default attachment point, and often used by default by mesh clothing makers).
  • However, the work on developing a fix has slowed as a result of resources being moved over to the teleport disconnect issue.

Asset UDP Messaging Deprecation

As noted in my SUG summary, it appears the code for the Asset UDP messaging deprecation didn’t work as anticipated, likely the result of one code element failing to merge correct. There will be a be a further RC deployment in week #16 with the corrected code.

A reminder that assuming the deployment is made and the code works as anticipated, anyone using very old viewers still reliant on UDP messaging for assets and which do not have support for HTTP messaging will not be able to receive any updates for the following: animations, body parts, clothing, gestures, landmarks, meshes and sounds whilst connected to regions on any RC channel.

In Brief

  • The are reports of issues with the EEP code interfering with Interest List culling, with Draw Distance having little effect on scene rendering (BUG-226752). This is being investigated.

2019 SL User Groups 13/3: TPV Developer Meeting

Sol Farm; Inara Pey, February 2019, on FlickrSol Farmblog post

The following notes are taken from the TPV Developer meeting held on Friday, March 29, 2019. A video of the meeting is embedded below, my thanks as always to North for recording and providing it. Time stamps are provided to the major topics of discussion, which will open the video in a new tab for ease of reference.

SL Viewer

There have been no updates to any viewers since my Simulator User Group summary. The viewer pipelines there remain as follows:

  • Current Release version 6.1.0.524670, formerly the BugSplat RC viewer February 13, promoted February 28 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):
  • 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.

[2:22-6:55]

  • The hope is the EEP RC viewer will be eligible for promotion to de facto release status “pretty soon”.  However, as per my CCUG summary, both the EEP viewer and the new-to-RC-status Bakes on Mesh viewer  are awaiting some fixes.
  • The Estate Access Management viewer is good-to-go, but is awaiting some simulator update with a new capability, which is likely to be another couple of weeks, before it can be promoted.
  • All of this means that the next viewer liable to be promoted will be Love Me Render viewer.

EEP Limitations

[7:24-25:00] There are also a couple of user-identified issues with EEP that are being considered:

The first is that EEP doesn’t play well with RLV and RLVa capabilities that use Windlight settings. LL have offered to help see what LSL abilities within EEP might be used to overcome the issues.

The second is potentially more disruptive: the ability to locally change an environment for the purposes of photography is somewhat limited.

Currently, with Windlight, it is possible for a photographer to tweak the local environment in their own viewer (e.g. move the Sun to provide better lighting / shadows, alter the cloud and haze density / colour, etc.).

Within EPP, this ability is limited to only those settings a user has a right to alter, make such minor adjusts potentially impossible to achieve. This is related to the EEP permissions system that has been set to allow EEP assets to be sold by creators.

The only options are either a): completely replace the location environment with one attached to their avatar; or b) trying to build a personal “copy” of the location environment just to adjust the Sun position, etc., or c) trying to employ LSL to make the necessary changes, with b) and c) clearly being hard for most people to achieve.

Whirly Fizzle has raised a feature request (BUG-225921) to bring the matter to LL’s attention, and it is being examined. However, whether or not an alternative means to make such localised (/ personal) tweaks to an environment will make the initial EEP release or be held over to “EEP 2.0” has not been decided.

One suggestion put forward at the meeting allowing such minor tweaks might be to allow make changes without exposing the associated underlying values for the settings (thus avoiding people being able to copy  / rip EEP assets that they would otherwise have to buy), and to have the Save options disabled when doing so. Rider Linden indicated this is one of the approaches he was considering looking at.

Reminder: the EEP simulator code is now grid-wide. This means certain render feature – such as the stars – appear to be “broken” on non-EEP viewers (e.g. black “stars” can appear in daytime skies as square blotches, and at night white stars appear decidedly square. This is because the sky (including the stars) is rendered differently with EEP, but an attempt is made to convert things like stars back to a windlight setting for rendering by non-EEP viewers, which doesn’t entirely work.

This issue will obviously be fixed when the EEP viewer code is available in all viewers.

Simulator Update

[6:56-7:20] Simulator releases have been fairly quiet of late, with some weeks seeing no roles on either the SLS (Main) channel or one or more of the RCs. However, there are a number of simulator projects in flight which mean things are liable to be busy with simulator releasing over the coming weeks.

Teleport Issues

Teleport Disconnects

[25:37-34:01]

  • It’s been widely noted that there has been a sharp up-tick in teleport failures & viewer disconnections (with physical region crossings also causing similar issues).
  • This problem appeared to start with a server deployment, but the root cause(s) is / are proving hard to identify.
  • It took the Lab a while to realise there was a problem, as the tool they use to monitor the success / failure rate of teleports was not showing any significant issues, and Lindens in-world assumed that when they encountered the problem, it was an issue with their own connection.
  • Investigations are now in progress, but identifying a root cause is difficult, as it is proving hard to get a consistent set of circumstances by which the disconnects can be reproduced.
    • If anyone can determine a means to repro the issue, or determine the conditions under which the problem is more / less likely to happen, they are asked to put it in a Jira for the Lab.
  • Some changes have been made to the simulator code in the hope that they might either a) help alleviate the problem, or b) at least provide more data when teleport disconnects do occur, and some of these changes are likely to be deployed in week #14.

Attachment Loss on Teleport

[34:09-36:59]

  • This is another issue that has been of increasing notice for a while now (e.g. inventory being actually detached; attachments being ghosted in your local view whilst others still see them attached; experience-controlled temporary attachments becoming ghosted, etc.).
  • The Lab does not have a solution for the problem as yet. However, via testing, they have found a number of issues that contribute to worn inventory being detached as a result of the teleport (/ region crossing).
  • Fixes for these issues are being developed, and more news on these should be available once the Lab has some definitive testing results.
  • The hope is that the Lab will able to resolve most of the issues  – or at least make things behave more correctly – just through changes on the server-side, rather than the fixes being heavily biased towards the viewer.
    • Any viewer-side changes that might be required will be highlighted at future TPVD meetings do that other viewers can take and merge them as required.

Other Items

Adult Rated In-Viewer Web Searches

[40:45-43:15]

Despite certain pundits claiming otherwise, the Adult rating is not all about “extreme sex and violence” (there are numerous residential, art, photographic, and role-play regions for example, that err on the side of caution and opt for an adult rating). However, a problem that does exist is that the web search in the viewer currently opens on the Events tab, and with the Adult search parameter enabled, this can result in sexually explicit adverts being displayed, which some who might otherwise be using Adult to rating simply to find the type of location noted above to be uncomfortable.

  • Unchecking the Adult search option isn’t a solution, as disables Adult searching in other categories thus preventing the art galleries, etc., mentioned above being listed in results.
  • One way to lessen this impact might be to make the Destinations tab the default tab on opening the web search panel. While this still has Adult destinations in the banner ads, these are more mixed with ads for destinations with other ratings, and potentially less noticeable.
  • Another suggestion offered is to possibly sub-categorise Adult search results between sexual / non-sexual (although this could be hard to achieve in avoiding issues of gaming).
  • The suggestion made for this issue to also be raised at the next Web User Group meeting.

 

2019 SL User Groups 11/3: TPV Developer Meeting

Forest of Astray; Inara Pey, February 2019, on FlickrForest of Astrayblog post

The following notes are taken from the TPV Developer meeting held on Friday, March 15, 2019. A video of the meeting is embedded below, my thanks as always to North for recording and providing it. Time stamps are provided to the major topics of discussion, which will open the video in a new tab for ease of reference.

There was a lot of general text chat during the meeting, there these notes are purely a summary of the key discussion points likely to be of interest to most users.

SL Viewer

[3:47-5:35]

There have been no SL viewer updates this week, leaving the current pipeline as:

  • Current Release version 6.1.0.524670, formerly the BugSplat RC viewer February 13th, promoted February 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):
    • EEP RC viewer version 6.1.1.525044, March 7th.
    • Love Me Render RC viewer, version 6.1.1.524929, March 6th.
    • Estate Access Management (EAM) RC viewer, version 6.2.0.524909, March 5th.
  • Project viewers:
  • Linux Spur viewer, version 5.0.9.329906, dated November 17th, 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 8th, 2015 – provided for users on Windows XP and OS X versions below 10.7.

Updates to the RC viewer have been delayed due to “some small problems” being revealed when the viewers were updated with a security update to  Chrome and Chromium), which affects all versions except the very latest, 72.0.3626.121. This is being addressed by Linden Lab, but it will take time for the patch to filter out to all viewers. In the meantime, the current internal SL web browser is potentially vulnerable; do not use it to browse non-LL websites on it, and avoid using media on a prim from untrusted sources.

In addition, EEP, EAM and Bakes on Mesh are all awaiting server-side updates, with EEP apparently being deployed to the rest of the grid in week #12 (Magnum and SLS).

Attachments Detaching

[9:28-20:50 (including a lot of text chat)] : Linden Lab is getting some “large-scale” testing done on attachments detaching (e.g. after a teleport or following region crossings).

  • Some of the tests have involved region crossings carrying more than the permitted number of attachments, and data from these experiments is still being gathered.
  • It has apparently proven difficult to consistently reproduce issues, which has delayed data gathering and investigation.
  • Part of the issue seems to still be wearing to many items on a single attach point (mesh items are particularly susceptible to this due to many creators simply utilising the default right hand attach point for their clothing, etc., rather than rigging to alternates).
  • Some have pointed to stressed (i.e. those bring over-used by avatars and scripted objects – such as busy shopping event regions) can exacerbate the issue, which could be the result of messages to / from the viewer being lost.
  • Others have suggested the issue is related to the complexity of attachments (visual and scripting).
  • Some testing by users has suggested that it a result of kill messages being received during multiple region crossings (e.g. an avatar crosses from region A to region B and then to region C, and gets missing attachments after crossing into C as a result of a kill message being received from region A causing the viewer to think something has been detached).

In Brief

  • [20:53-28:07 (including text chat)] Inventory Requests During Log-In: the viewer has a series of tags related to inventory requests that are used during the log-in process. LL has asked TPVs to check on to see if they have made any changes to how the tags are used, as changes may be coming as an overall part of the project to improve inventory robustness.
  • [32:16-32:40] Group  tag change/group role change throttle: the is currently a means for users to change their group tag and role rapidly using RLV/a scripting. However, this can put enormous strain on server-side services. Because of this, LL are introducing a server-side throttle on requests to change group tag information, and it appears likely that this will be deployed in week #13 (commencing Monday, March 25th, 2019).
  • [33:08-37:15] Video playback issues:
    • Autoplay of You Tube videos within the viewer appears to be broken, and a check on recent server changes will be made to see if there is anything in particular that might be responsible.
    • There are no plans for further Chrome Embedded Framework (CEF – media playback) updates until after the work on updating the viewer build process to Visual Studio 2017 has been completed.
    • It is possible that after the VS2017 upgrade, the Lab may be able to re-enable codec support for playback of MP4 format videos – although there is no time frame for this happening at present.

2019 SL User Groups 9/3: TPV Developer Meeting

The following notes are taken from the TPV Developer meeting held on Friday, March 1st, 2019. A video of the meeting is embedded below, my thanks as always to North for recording and providing it. Time stamps are provided to the major topics of discussion, which will open the video in a new tab for ease of reference.

There was a lot of general text chat during the meeting, there these notes are purely a summary of the key discussion point likely to be of interest to most users.

SL Viewer

[0:44-4:48]

As noted in my CCUG Summary for the week:

  • The BugSplat RC viewer, version 6.1.0.524670, was promoted to de facto release status on Thursday, February 28th.
    • This has resulted in breakage for some open-source builds, and the Lab will be accepting patches to correct this, providing the patches do not interfere with the BugSplat changes.
    • There will likely be further fine tuning of the BugSplat code to assist with the reports generated.
  • The EEP viewer was promoted to RC status with the release of version 6.0.2.524683 on Wednesday, February 27th.

The remaining viewer in the pipelines remain as follows:

  • Release channel cohorts (please see my notes on manually installing RC viewer versions if you wish to install any release candidate(s) yourself):
    • Estate Access Management (EAM) RC viewer, version 6.1.0.524240, dated February 22nd.
    • Love Me Render RC viewer, version 6.0.2.523177, dated January 16th.
  • Project viewers:
  • 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, dated May 8th, 2015 – provided for users on Windows XP and OS X versions below 10.7.

The EAM viewer requires a further simulator update, and there will be further simulator updates / deployments for EEP (which is not yet grid-wide).

The new Maintenance RC viewer – code-named Teranino (after the Croatian liquer) – has been delayed while it is being merged up to the BugSplat release. Among other things, this RC will have numerous crash fixes in it.

Also as noted in my CCUG summary, the Bakes on Mesh viewer is awaiting a Bake Service update. Once that has been deployed, the viewer will likely be promoted to RC status.

Asset UDP Messaging Deprecation

[4:54-6:08] The simulator update to remove the remaining Asset UDP messaging was delayed as a result of the week #9 deployments having to be deployed. The initial deployment of the changes will, I believe, be made to the Magnum RC channel.

As these updates are deployed the current Obsolete Platform viewer and the Linux Spur viewers will be increasingly unable to receive asset data – including avatar shapes, meaning avatars used using them will appear as clouds. These viewers will not be updated to render avatars, and will not be updated to enable them to do so.

In Brief

  • [22:29-22:52] Texture memory caching: this work is stalled at present, but LL hope to resume the work soon.
  • [23:12-23:35] Visual Studio 2017 update: “Good progress” is being made on the shift to using VS 2017 in the viewer build process, and it is hoped tested on the updated build process can commence in a few weeks.
  • [28:38-28:48] Avatar attachment issues: the issue of attachments belonging to other avatars randomly appearing to be briefly attached to your screen when logging-in to / teleporting to busy regions is thought to be the result of a race condition, with the viewer receiving object data for attachments before it gets the necessary avatar / attachment point data. While the problem does correct on receipt of the latter, LL are continuing to investigate.
  • [7:06- 19:23 – mainly in text chat] NiranV Dean (Black Dragon viewer) believes he has noted two performance improvement areas:
    • A means to prevent fps collapse when edit-selecting rigged mesh. He has offered to set up a repository so his ideas on this can be examined.
    • A means to reduce the number of getChild calls generated when using tools such as the Edit window (some TPVs may have already implemented fixes to reduce these calls).
    • Using sliders to make changes to glow and transparency (and possibly to materials – e.g. shine and glossiness, although the workflow here would be more complicated) to reduce the number of callbacks being made.
    • There is a willingness at the Lab to look at his ideas, once they’ve been submitted  / made available.
  • [29:38-31:31 (and beyond in chat)] General discussion on avatars appearing to float above platforms floors at altitude. In short, this is nothing to do with further height offset issues, but likely the result of floating point precision options (the same issues that can lead to things like “prim drift” when building at altitude). Any attempt to redress this could be a major project, if not a fundamental change in how the simulator works.
  • A presence of the Singularity team at the meeting led to suggestions a release for that viewer might be somewhere on the horizon.

A video of the meeting is embedded below, my thanks as always to North for recording and providing it. Time stamps are provided to the major topics of discussion, which will open the video in a new tab for ease of reference.

SL Viewer

[0:00-1:18 and 3:54-4:15]

The Bakes On Mesh project viewer updated to version 6.0.2.524367 on Friday, February 15th. The rest of the current viewer pipelines remain as per earlier in the week:

  • Current Release version 6.0.1.522263, dated December 5, promoted December 13. Formerly the Spotykach Maintenance RC viewer – 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):
    • BugSplat RC viewer, version 6.1.0.524348, February 13. This viewer is functionally identical to the current release viewer, but uses BugSplat for crash reporting, rather than the Lab’s own Breakpad based crash reporting tools.
    • Estate Access Management (EAM) RC viewer, version 6.1.0.523351, January 23.
    • Love Me Render RC viewer, version 6.0.2.523177, January 16.
  • 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. This viewer will remain available for as long as reasonable, but will not be updated with new features or bug fixes.

It is hoped that one of the current RC viewers will gain promotion to de facto release status, although there is one further issue in the Love Me Render viewer to be seen to. Also, the EEP viewer could see promotion to RC status in the very near future.

Viewer-Related Web Changes

Release Notes

[16:35-18:20] The Lab will be introducing a new system for release notes. In short:

  • It will use a new website for publishing release notes, and not the currently SL wiki pages.
  • Those release notes currently on the wiki will remain there for archival purposes.
  • Once visible, any issues should be reported via Jira.

User Profiles – Viewer and Web

[18:23-24:35] The current user profiles seen in the viewer, on the web, via various feeds, etc., are all currently powered by a single application. There is an upcoming system upgrade in the pipeline that might result in some breakage within this app. The Lab will therefore be moving viewer profiles back to using floater-style user profiles, as is seen with the like of Firestorm.

Upcoming changes will impact the current means of providing profile information. In particular, this means the official viewer will, in the future cease using the web format for displaying profile information (l) and will revert to a more “legacy” style, as seen in various TPVs (like Firestorm, shown r).

It is not currently clear what will happen to the current web profiles and feeds. It is hoped these will be able to continue to work, but the Lab is also contemplating a “worst-case” scenario that they may be retained for historical purposes (so snapshots uploaded to feeds are preserved and remain viewable, for example), but will no longer work as they do now – but this is not what the Lab is hoping to achieve.

This will not be an immediate change, as there may be issues along the way the Lab need to work through.

Weekend Issues

[5:27-6:31] The weekend of February 9th /10th saw some significant issues with Second Life, and extended periods of unscheduled maintenance. The problems that contributed to the issues are still being investigated, ut the Lab is close to understanding exactly what went wrong, and how to respond should a similar issue occur.

As an aside, the weekend issues result in inventory problem that caused some uses to see the “cannot remove protected categories” error. If you are still seeing this message, and have not already done so, file a support ticket.

In Brief

  • [1:20-1:46] Visual Studio 2017 Build Process Update: work on this is progressing well, but will like pause in the coming week, due to the project lead being on vacation.
  • [2:09-2:40] EPP: As per my SUG meeting and CCUG meeting notes, the simulator EEP code is now on BlueSteel and LeTigre. This will not get a further promotion in week #8, as there is a fix for another issue the Lab wants to see get wider exposure on the grid.
  • [6:50-10:18] Avatar attachment issues: there have been reports of attachments belonging to other avatars randomly appearing to be attached to your screen when logging-in to / teleporting to busy regions. The underlying problem appears to be a race condition in which the object data for the attachment is received by the viewer ahead of the avatar / attachment point data (and should correct when the latter is received).
    • In the meeting, the issue is specifically reported as occurring with “jellydolled” avatars, but this appears to be purely coincidental.
  • [10:39-11:28] New EEP Assets causing log-in freezes: a default set of new EEP object types were added to the asset library recently for use with the EEP viewer. However, if pulled into a non-EEP viewer, they can cause log-in freezes, as the viewer repeatedly generates an error message for each individual asset it encounters in loading inventory, rather than simply throwing a single message of the asset type, and simply ignoring the rest of the individual assets. There is a fix for this, but it has yet to reach the current release viewer code base.
  • [11:37-14:10] Landmark assets getting fetched twice at log-in: this appears to be a new(ish) issue. Although landmark assets only appear once in inventory, the viewer appears to be fetching them twice; once around mid-way through the log-in process, and then again at the end. The cause is unknown at present, but it has been noted by the Lab.
    • An intermediate workaround if your logins are being delayed unduly is to delete you landmarks.
    • This can might cause the degraded performance message (see below).
  • [13:07-15:33] Degraded performance message: “Linden Lab has detected degraded performance on your connection”, with a suggestion you relog, is a message users might receive when the viewer is failing to acknowledge enough of the UDP messages exchanged with the simulator.
    • This can be the result of your router being overloaded by whatever else it might be doing, so responses from the viewer fail to reach the simulator.
    • It might also be the result of issues being experienced in the simulator.
    • While a lot of asset-related UDP messaging has been removed from simulator / viewer communications, there is still much that does require / well suited to UDP, particularly where information is changing, and the viewer needs the latest update, not a re-send of a now outdated updated (e.g. object updates), as would be the case using something like TCP, which attempts to re-send the data it has, rather than any new data.
    • See also BUG-225544.
  • BUG-226352 requests allowing users to define more than a single resolution when uploading a texture

    [30:21-31:37] In-Viewer Animation Creation: This is a project based on contributions from NiranV Dean (Black Dragon viewer). Vir and Nat Linden had been working on elements of the project, but are both also busy with other viewer-related projects (e.g. Animesh follow-on investigations for Vir, working on the VS 2017 update for Nat). Resources are also being swallowed by the under-the-hood work required for the transition to the cloud, which is also impacting assorted projects.

  • [32:18-32:35] Texture resampling & mipmap availability: this has been the subject of extensive blog and forum discussions – see my week #7 CCUG summary) One outcome of this is Beq Janus has filed a feature request so users can define more than a single resolution when uploading a texture (see the dummy uploader floater design, right). The hope is this might encourage more people to make better choices about texture resolution use (very high resolutions aren’t always required, depending on how / where they are used, but can result in unnecessary texture memory use if unwisely employed).
  • [32:39-32:50] Asset UDP messaging deprecation: Aura Linden is now engaged in this work. This will include removal of the GrantUserRights message (found in LL PropertiesProcessor::sendfriendrights() ), which has been completely disconnected in the viewer since 2.0 days.TPVs are asked to check their code to confirm removal of the message path will not cause them problems.
  • [34:37-35:19] Does SL use multi-threading: yes, in parts of the viewer and the simulator code, but not as extensively as the Lab would like.

2019 SL User Groups 5/3: TPV Developer Meeting

Zimminyville; Inara Pey, December 2018, on Flickr

The following notes are taken from the TPV Developer meeting held on Friday, February 2nd, 2019. A video of the meeting is embedded below, my thanks as always to North for recording and providing it. Time stamps are provided to the major topics of discussion , which will open the video in a new tab for ease of reference.

Note that, as per the warning at the start of the video, there was an immature attempt to disrupt the meeting using voice / audio, and so there are lengthy periods of silence in the video to mute out the attempts.

SL Viewer

There have been not updates to any of the official viewers through week #5, leaving the pipelines as follows:

  • Current Release version 6.0.1.522263, dated December 5, promoted December 13. Formerly the Spotykach Maintenance RC viewer – 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):
    • BugSplat RC viewer, version 6.1.0.523335, January 23. This viewer is functionally identical to the current release viewer, but uses BugSplat for crash reporting, rather than the Lab’s own Breakpad based crash reporting tools.
    • Estate Access Management (EAM) RC viewer, version 6.1.0.523351, January 23.
    • Love Me Render RC viewer, version 6.0.2.523177, January 16.
  • 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.

[00:00-2:57] The three RC viewers have all had recent issues which have prevented their promotion to de facto release status.

  • Of the three, the EAM RC might be the closest to being ready for promotion.
  • The Bugsplat RC has been delayed due to the need to remove the code that allowed the viewer to be installed on Windows at account level, rather than at Admin level due to internal issue with Second life :URLs not working. This will require a further RC release before the viewer is liable to be ready for promotion.

Visual Studio Update

[2:49-3:42 and 19:50-21:51] The work to update the viewer build process to use Visual Studio 2017 is progressing well, with the focus on rebuilding all the various libraries need by the viewer to use VS 2017. The move to automate as many of the update processes as possible when updating the Visual Studio 2013 a couple of years ago means that this update should be significantly easier.

One outcome of this work is that when complete, it will allow LL to provide better  customised CEF support.

Environment Enhancement Project

[3:45-4:53 and 18:00-19:29] Please see my January 31st CCUG summary for a complete update. In brief:

  • A further simulator RC roll expected in week #6.
  • The viewer is close to being ready for promotion to RC status, and the next update should include a lot of bug fixes.
    • When this happens, it will not include crepuscular rays (and possibly some other atmospheric effects) due to performance issues that are still being worked on. Hopefully the capability will be added in the near future.
  • A final decision on capabilities that would make the cut for the initial viewer update / the release was due after the TPVD meeting, so expect further updates possibly at the week #6 SUG meeting.

Non-HTTP Asset Fetching / UDP Path Deprecation

[17:16-17:45] The work to remove all asset fetching UDP messaging from the simulator code will see the updated code deployed to Aditi in DRTSIM-400 (pre-RC readiness). It will then appear in an RC release on the main grid some time in the next couple of weeks. Once deployed, this will mean anyone using really old viewers that do not have HTTP asset fetching will no longer be able to obtain responses to asset requests.

Linux Viewer News

[21:54-23:20] The Lab is starting to receive some good input from Linux contributors to help get the official Linux flavour of the viewer back up and running. As noted in my previous TPVD meeting summary, this may not be a 100% functional version of the viewer; for example, Voice will likely not be supported, due to the fact that Vivox no longer supports Linux, and internal changes to the viewer mean that older version of the Linux voice plug-in will not work with the current viewer code. Those that need voice on Linux can try running the Windows SLvoice EXE (or even the entire Windows viewer) under Wine or similar emulation.

Other Items

  • [9:46-11:05] Mac OS voice issues: these are known about by the Lab. The Mojave issue cane be solved by giving the voice application permission to use the microphone; if users can’t get the permission dialogue, the route (for now) is to delete the viewer completely and re-install – just be sure to keep an eye out for the dialogue after the re-install and when trying to use voice (check all your monitors, check behind other open application windows, etc.).  There is also a contributed fixed from Firestorm’s Tonya Souther (and currently in the BugSplat RC) that should also help with Mac OS voice issues.
