SL project updates 23/1: server, TPV Developer meeting

Posted on by Inara Pey

Crestwick Island; Inara Pey, June 2015, on Flickr Crestwick Island (Flickr) – blog post

The following notes are primarily taken from the TPV Developer (TPVD) meeting held on Friday, June 5th. A video of the TPVD meeting is included below, with any time stamps in the following text referring to it. My thanks as always to North for the recording and providing it for embedding.

Server Deployments Week 23 – Recap

There was no deployment to the Main (SLS) channel on Tuesday, June 2nd, due to the week #22 RC deployment being rolled-back.

On Wednesday, June 3rd, all thee RCs received the same server maintenance package, which was the same update which had been attempted in week #22, but with additional back-end fixes to prevent a repeat of the earlier problems. The update comprises:

  • A change logic on accessing group member lists for large groups
  • Internal server logging changes.

SL Viewer

On Thursday, May 3rd, the attachment fixes RC viewer (Project Big Bird) updated to version 3.7.30.302190.  Presumably, this update is to bring the viewer up to parity with the current release viewer (formerly the avatar layers update), and so will hopefully clear the way for it to be promoted to the de facto release viewer in the near future.

[02:40] A new maintenance fixes RC viewer should be appearing in the release channel soon, the should also be an update to the Mesh Importer project viewer (currently version 3.7.28.300878) appearing soon; and work is progressing on updating the Oculus Rift project viewer.

Experience Keys (/ Tools)

[03:35] Work is continuing on the back-end of the Experience Keys systems prior to the capabilities being formally released across the grid as a whole.

“We are making progress on the back-end issues that have been delaying that,” Oz Linden informed the TPV Developer meeting. “But as far as I’m aware, we have not yet  … uncovered a viewer-related problem with that. so far these are all back-end related issues.” He went on:

To be a little bit more transparent, it’s really scaling issues. Experience actually work just fine at the scale we’re using them right now … but what we’re concerned about is what will happen when we turn them loose on a much, much larger population and there are lots more experiences running and there are a lot more simulators with experiences running on them. 

So what we’ve doing … is fairly intensive scaling and performance testing and we’re solving the problems that the testing uncovers. So, we’re making progress on it, and we’re fairly confident the problems are solvable, but we have run into a whole host of assorted issues with that.

In the meantime, it is expected that the current RC release of the Experiences viewer (currently version 3.8.0.300963) will be brought up to parity with the release viewer during week #24.

Viewer-Managed Marketplace

[05:53] For ease of reference, please refer to my update on VMM, available here.

Land Bans

[17:58] Oz Linden has issues an invitation to open-source contributors to assist the Lab in trying to improve the management of land ban lists. Again, for ease of reference, please refer to my separate report on this, available here.

Group Membership Changes

[22:15]  The update to the server RC channels referred to as “a change logic on accessing group member lists for large groups”, as noted in the server deployments recap at the top of this article, refers to a new way in which the members lists for larger groups (5,000 members and over) are handled.

In brief, the members lists for such groups will no longer load in the group floater in the viewer, unless the person attempting to see the list is in a role which requires they need to be able to do so. While this change is discussed within the meeting, I have been specifically asked not to blog on the change until it is deployed to the Main (SLS) simulator channel on Tuesday, June 9th, when I’ll have the details in full.

Unified Snapshot Floater

[33:12] As I’ve recently reviewed, NiranV Dean has updated the unified snapshot floater in his Black Dragon viewer. As he originally contributed the code for this floater to the Lab, he has also raised a JIRA (see BUG-9325) listing improvements and fixes and has contributed his updated code. This has been under review at the Lab, and commenting at the TPV Developer meeting, Oz indicated that the Lab are “fine” with the majority of Niran’s suggestions, although there are a couple that appear to be subject to further consideration, which might take a little while to sort through.

NiranV Dean's unified snapshot floater improvements, including the separate, resizeable preview panel, are now with the Lab, although it is not yet entirely clear which of the updates will be adopted, or when they will appear in the official viewer.

SL project updates week 20/2: TPV Developer meeting, VMM

The following notes are primarily taken from the TPV Developer (TPVD) meeting held on Friday, May 15th, and from the Server Beta meeting held on Thursday, May 14th. A video of the TPVD meeting is included below, with any time stamps in the following text referring to it. My thanks as always to North for the recording and providing it for embedding,

Server Deployments, Week 20 – Recap

As always, please refer to the server deployment thread for the latest updates / news.

There was no Main (SLS) channel deployment on Tuesday, May 11th. On Wednesday, May 12th, the three RC channels were all updated with a new server maintenance package, comprising internal server logging changes, back-end system bug fixes, reply-to email changed in postcard sends (see below for more).

Group Chat

The Server Beta User Group meeting on Thursday, May 14th, saw a test of a group chat update it is hoped will fix the issue of some people not seeing all or some chat when the group chat window is open (see BUG-9130). The test appeared to yield positive results, with Simon reporting no unusual event logging. The problem here is that the instances of the problem seem to be so rare, it’s hard to guarantee a small sampling of testers will catch any problems which might still exist.

SL Viewer

[00:15] It has been a quiet week on the viewer front. As noted in part 1 of this week’s report, the attachment viewer (Project big Bird) reached RC status, other than that there has been not additional movement with either the current selection of RC and project viewers.

A further update to the mesh importer project viewer (currently at version 3.7.28.300878) is with LL’s QA team and should be released relatively soon. Updates are also being made to the Viewer-Managed Marketplace project viewer (which is likely to go to RC status once through LL’s QA process) and the Oculus Rift project viewer.

Snapshots to E-mail

[02:22] Commenting at the TPV Developer meeting, Oz Linden gave a little more information on the “reply-to email changed in postcard sends” update deployed to the RCs, indicating this was indeed a fix aimed at preventing snapshot to e-mail being tagged as spam by ISPs and a/v software due to the way they handle the “from” field (see my TPV Developer meeting report for week #17), which had caused the Lab to consider removing the snapshot to e-mail capability.

“Instead,” Oz told the meeting, “we found we could get around that by sending the e-mail differently … So the way it’s changed now is that instead of sending the ‘from’ address as the sender’s address, we send the ‘reply-to’ address; and the ‘from’ address is ‘no-reply@secondlife.com’ … so that ducks the problem of us looking like spammers who are forging invalid addresses.”

This should hopefully negate any need to remove the snapshot to e-mail capability, and retain compatibility with sending snapshots to the likes of Snapzilla and the SLU forums.

Unified Snapshot Floater

[04:40] NiranV Dean, who submitted the unified snapshot floater to LL (and which has most recently been integrated into Firestorm among the TPVs) asked if there had been any feedback on it. Both Oz and Grumpity Linden indicated that overall, feedback has been positive, although some have complained at the amount of screen real estate it takes up with the preview panel open. As this allows the snapshot preview to match the aspect ratio of the user’s screen, there’s not a lot that can be done about it – and the preview window can always be closed / the panel minimised when initially setting-up shots.

The unified snapshot floater - further work is being carried out by TPV devs for contribution to LL, including the possible full integration of the Facebook, Flickr and Twitter upload options
The unified snapshot floater – further work is being carried out by TPV devs for contribution to LL, including the possible full integration of the Facebook, Flickr and Twitter upload options

Niran is proposing a further set of updates (one of which, a fix for auto snapshot, is in the works at the Lab), including possibly making the preview screen detachable from the main floater.  Cinder Roxley also indicated she is working on fully integrating the Facebook, Twitter and Flickr options into the main snapshot floater (they currently retain their own floaters due to the authentication workflow required for each. This work will be contributed to the Lab for consideration / integration when complete.

Viewer-Managed Marketplace (VMM)

[08:09] Over the last two weeks, as a part of the on-going beta of VMM, around 15-20 volunteers have had their stores migrated by the Lab from Direct Delivery to VMM. Brooke linden reports that the exercise has uncovered “pretty much minor issues” which the Lab can address. A further batch of volunteer migrations is planned to help further test the robustness of the process in the next week or so.

As noted above, the VMM viewer is now heading for an RC release once it has cleared LL’s QA testing. However,  the time frame on when this might happen is a little vague; it might be in the next week or so, or it might be longer.

Avatar Complexity

[17:34]  The next Snowstorm contributions viewer is progressing internally at the Lab. This is the viewer which includes the new Avatar Complexity (aka “Jelly Babies” or “rainbow avatars”) functionality which allows users to define a level of complexity (a weighting number) which will render any avatar exceeding that value as a solid colour, rather than a full avatar. The aim of this is to help reduce the rendering load placed on people’s computers, particularly in very busy locations. The value is adjustable, as so can of course be varied to suit your current needs.

Avatar complexity is intended to help those who may hit performance issues as a result of their GPU struggling to render complex (hight render cost) avatars, by rendering such avatars as solid colours.
Avatar complexity is intended to help those who may hit performance issues as a result of their GPU struggling to render complex (hight render cost) avatars, by rendering such avatars as solid colours.

A slight hiccup has occurred in that in making some changes to the code, Oz accidentally broke the code such that instead of rendering as a solid colour, avatars exceeding the limit are currently rendering as transparent, and this is yet to be fixed. Code has been added to the viewer to report how many people around you are rendering your avatar as a solid colour (should your avatar be complex enough to be rendered thus), but this has yet to be made visible through the viewer UI, and simulator support for this is now in place on the RC channels and will be rolled to the Main channel in the coming week.

Mac Updates

[19:36] Cinder Roxley has a set of contributions for using the viewer with Mac Retina displays ready to go to the Lab, and it seems likely these will flow into a further Snowstorm contributions viewer in development alongside the one containing the Avatar Complexity updates.

A question was also asked whether there were plans to update the Mac viewer to use a newer OpenGL core profile. The Lab is not working on this, as their rendering team believe there is little or no benefit to be gained from it. However, they would accept any contributions offered for consideration (subject to a “long, terrible QA process”). However, a good part of this would require working through some eight years of OpenGL code.

SL project updates week 18/2: TPV Developer meeting

Posted on by Inara Pey

Server Deployments Week 18 – Recap

As always, please refer to the server deployment thread for the latest news.

SL Viewer

[00:30] All of the viewers currently in the release channel as RCs are currently being updated to match the current release viewer, version 3.7.28.300918, which uses the new viewer build tool set.

Experience Keys / Tools

[02:06] The Lab is still making headway on the back-end issues they wish to clear before they promote the Experiences RC viewer to the de facto release viewer.

Attachment Fixes

[02:20] The attachment fixes project viewer (Project BigBird), currently at version 3.7.28.300856, is expected to appear as a release candidate viewer very soon – most likely in week #19. It is thought this viewer fixes all of the attachment issues associated with AIS v3, although there are some attachment issues which occur server-side which it does not correct, such as failures with requests to attach multiple items (such as during an outfit change).

Oculus Rift Project Viewer

[07:22] As noted in my last TPV Developer meeting report, the Lab is resuming work on the Oculus Rift project viewer. The focus on this will be to ensure the viewer works with the latest Oculus SDK (it is currently running behind SDK releases), and also up to the latest viewer source.

Once this has happened, it is likely that the viewer will enter the release channel as a release candidate viewer, so that it can keep pace with updates to the release viewer, and from there progress to release status. How quickly this will happen is dependent upon a lot of different factors, and it is likely to remain the last in line to become the release viewer for a good while, partly because it is unlikely the Oculus Rift will be available as a consumer item until 2016, and so there will be other things entering the release channel which have broader usage within the SL community, and will therefore be promoted more quickly.

Viewer-Managed Marketplace

There was a Viewer Managed Marketplace meeting on Friday, May 1st, immediately prior to the TPVD meeting, and a transcript of that meeting, with recording, is now available.

SL project updates week 17/2: TPV meeting – CEF, Inventory

Posted on by Inara Pey

Fantasy Faire 2015: YoZakura; Inara Pey, April 2015, on Flickr Fantasy Faire – April 23rd to May 3rd, 2015: YoZakura (Flickr)

The following notes are primarily taken from the TPV Developer meeting held on Friday, April 24th,  a video of which is included below (my thanks as always to North for recording it and providing it for embedding), and from the Server Beta meeting held on Thursday, March 26th. Any time stamps contained within the following text refer to the TPV developer meeting video.

Server Deployments, Week 17 – Recap

As always, please refer to the server deployment thread for the latest updates.

  • On Tuesday, April 20th, the Main (SLS) channel received the server maintenance package deployed to all three RC channel in week #16, which comprises internal server logging changes and new flags for llGetObjectDetails()
    • OBJECT_BODY_SHAPE_TYPE – returned list entry is a float between 0.0 and 1.0. Anything > 0.5 is male, otherwise female; -1.0 if the avatar is not found
    • OBJECT_HOVER_HEIGHT – returned list entry is a float, -1.0 if the avatar is not found.
  • There were no deployment or restart on the three RC channels on Wednesday, April 22nd.

SL Viewer Updates

[05:50] The Tools Update viewer, version  3.7.28.300918, was promoted to the de facto release viewer on April 23rd – see my article here for details. During its run as an RC viewer, this release had around a 2% lower crash rate than the release viewer built using the “old” tool set and processes.

As a result of this, all the remaining RC and project viewers are being updated to match the release viewer code base, and updated versions should be appearing soon.

Attachment Fixes Viewer (Project BigBird)

[07:42] This viewer, current available as a project viewer – version 3.7.28.300856 – and which fixes a range of issues related to avatar attachment failures, is in the process of being updated to a Release Candidate status, and should be appearing in the release pipeline as such in week #18.

[29:28] The Lab believes that these fixes resolve all of the viewer-side issues related to attachment problems which are related to AIS v3. However, a number of the more noticeable issues  – such as problems with attachments being detached on teleporting – are server-side, and require further investigation / fixing.  Similarly, failures with requests to attach multiple items (such as during an outfit change) also appear to be simulator-related, rather than anything within the viewer or linked to AIS v3.

Oculus Rift Viewer

[07:55] The Oculus Rift viewer is now on the schedule to be updated and brought into line with more recent viewer code releases. There is no set time scale for this project (and the Oculus Rift itself, according to Oculus VR, is unlike to reach a consumer release in 2015), but the aim is to bring it back to a “more active” state.

Viewer-Managed Marketplace

[00:08] Brooke Linden gave an update on VVM – as this is of interest to a potentially wider audience than those interested in viewer development, I’ve provided a separate article on it.

Web Media (Webkit and CEF)

[08:41] The Lab is making “pretty good” progress on replacing webkit, an increasingly outdated third-party library used within the viewer for powering the built-in web browser, displaying web profiles and powering in-world media (TVs, MOAP, etc.), with the Chromium Embedded Framework. The Mac work is lagging a little behind this, but the Lab has now called-in external expertise to help move the project forward as a whole.

Request for TPV / Open-source Support for Linux

[09:17]  The Lab is seeking support from TPV developers and the open-source community to help maintain and move the Linux flavour of the viewer forward. For details, please see my  separate article in this blog, complete with an audio extract from the meeting.

Snapshots to E-mail

[12:27] The send snapshot as e-mail capability is in the process of being removed from the viewer.

The main reason for this is that wherever possible, snapshots are sent via the “secondlife.com” domain, but use the sender’s own e-mail address as the originating address in the “from” field of the sent e-mail which appears as if the “from” address is being forged. This, and other ways in which e-mails flowing out from “secondlife.com” are handled, has resulted in some ISPs regarding the domain as a spam domain, and have been pro-actively blocking it (Germany-based GMX is one such example).

To rectify these problems, the Lab is reviewing how e-mails from “secondlife.com” are being managed as a whole, and eliminating those uses which may conceivably lead to the domain In the case of the snapshot floater, the Lab’s perspective is that the easiest way to fix the problem is to remove the option from the snapshot floater; however as was pointed out to them in the meeting, this will break content such as wardrobe HUD systems which utilise the snapshots to e-mail functionality.

Other Items

HTTP and CDN Use Expansion

[20:35] The Lab is working on increasing the number of assets such as animations, sounds, and gestures, consumed by the viewer to being delivered via HTTP the CDN, and removing the reliance on UDP. This is for a number of reasons:

  • It further fees-up resources on the simulator to do what they do best – simulate the world around us, rather than using them for managing UDP file transfers
  • The use of UDP is not the most efficient or robust means of carrying out these transfers
  • UDP is bad for the network; there’s no flow control packet or congestion control behaviour, it can result in high packet losses which may occur anywhere between the the server and the viewer, and thus be hard to identify and prevent in future, etc.

As this work progresses, the Lab will be removing the server-side support for the UDP messaging currently used by such transfers. This has already happened with inventory fetching (and the option to disable HTTP Inventory is due to be removed from the viewer), and will be happening soon with texture fetching (which will also see the removal of the option to disable HTTP Textures in the viewer).

To help with this, TPVs are being encouraged to work with the Lab to identify specific / reproducible  issues users are encountering vis HTTP, etc., so that more work can be put into fixing them, and the Lab is asking TPVs not to recommend to users to switch back to the “old ways” of doing things when potential HTTP problems are encountered, as the 2old way may not be around for much longer.

SL Project updates week 15/2: TPV Developer meeting

Posted on by Inara Pey

Tillicum Island; Inara Pey, March 2015, on FlickrTillicum Island (Flickr) – blog post

The following notes are primarily taken from the TPV Developer (TPVD) meeting held on Friday, April 10th, and from the Server Beta meeting held on Thursday, April 9th. A video of the TPVD meeting is included below, with any time stamps in the following text referring to the video. My thanks as always to North for the recording and providing it for embedding,

Server Deployments Week 15 – Recap

As always, please refer to the server deployment thread in the forums for the latest information and updates.

  • On Tuesday, April 7th the Main (SLS) channel received the server maintenance update previously deployed to the three RC channels, which sees UDP inventory messaging deprecated (HTTP Inventory in the viewer MUST be enabled for your inventory to fetch correctly / your avatar to render in your view –  details here and further notes below)
  • On Wednesday, April 8th all three RC channels received a new server maintenance package comprising a crash fix, minor CDN configuration updates and an internal server configuration update.

HTTP Inventory

[15:18] The Lab is still planning to remove the HTTP Inventory option and setting from their viewer “soon”. In addition, as a part of their overall work on improving inventory handling, the Lab is planning on removing the viewer-side code for UDP inventory fetching from their viewer, citing the time frame in which this is likely to happen as being “weeks or months, more likely months”.

Firestorm has already removed the option in preparation for their upcoming release, and has set that viewer so that if anyone currently has HTTP Inventory disabled, it will automatically be re-enabled in installing the new release over their older version.

Forthcoming Deployment

A new change destined for the RC channels is an update to llGetObjectDetails(), which adds new functions for avatar shape identification and hover height:

  • OBJECT_BODY_SHAPE_TYPE – returned list entry is a float between 0.0 and 1.0, -1.0 if the avatar is not found
  • OBJECT_HOVER_HEIGHT – returned list entry is a float, -1.0 if the avatar is not found.

SL Viewer

Avatar Layer Limits

[03:00] The Avatar Layer Limits viewer updated from project to RC status with the release of version 3.7.27.300567 on April 9th. This allows users to wear up to 60 wearable layers (jackets, shirts, tattoo, alpha, etc.) in any combination. Until these updates reach the main viewer (and all TPVs), those using it will find their layers will only adhere to the new global limit whilst using this RC viewer.

A update to the baking service which will enforce the new global limit  will be deployed once it has passed LL’s QA testing.

[05:23] Again, please note that this update only applies to avatar wearing (clothing) layers; it does not apply to attachments, which remain at the global limit of 38. The Lab currently has no plans to alter this, not only because they’re work to resolve a series of attachment issues, but also because large numbers of attachments on avatars can impact viewer performance due to the way in which they are handled.

[11:38] The above notwithstanding, a further update to the attachment fixes project viewer (currently at version 3.7.27.300377) is expected soon, possibly in week #16.

Maintenance Viewer

[06:36] The Maintenance RC viewer updated to version 7.27.300636 on April 9th. This viewer includes multiple fixes and improvements. It now appears that all of the issues reported against this viewer when first released have now been resolved, and subject to the performance of this new version as an RC, it looks set to be promoted as the next de facto release viewer.

Tools Update Viewer

[08:50] The “final” set of fixes and updates for the Tools Update RC viewer (currently version 3.7.27.300242) are with the Lab’s QA team. If all goes according to plan, these should be appearing shortly in an update to the RC viewer, which should then place it as the next-in-line for promotion to the de facto release viewer  after the Maintenance RC has been promoted.

Once this viewer does reach release status, it will mean the Lab will have switched to the new viewer build process. As a result, the official viewer will no longer install on Windows XP or versions of Mac OS X below 10.7. This will also be true of any TPVs which fully switch to the the new build process in the future.

Viewer-Managed Marketplace

[00:00] The first element of the server-side deployment occurred in week #15. However, there are two further elements awaiting deployment, which will roll-out to the servers over the next two weeks. So the Lab is hoping that things might be ready for wider beta testing to commence in the week #17 (commencing Monday, April 20th).

The following notes are primarily taken from the TPV Developer meeting held on Friday, March 27th,  a video of which is included towards the end of the article (my thanks as always to North for recording it and providing it for embedding), and from the Server Beta meeting held on Thursday, March 26th. Any time stamps contained within the following text refer to the TPV developer meeting video.

Server Deployments Week 13 – Recap

As always, please refer to the deployment thread in the forums for the latest updates / news.

  • On Tuesday, March 24th, the Main (SLS) channel received the server maintenance package deployed to the three RCs in week 12, comprising updates which allow the Lab to make various configuration changes without having to necessarily run a rolling restart when they have done so. It contains not actual functional changes to the simulator software
  • On Wednesday, March 25th, the three RC channels received the same new server maintenance package, which is focused on inventory loss issues, and provides the Lab with better error detection and logging, improving their ability to look at some of the failure places and the removal of unused code. This updates does not remove the server-side messaging used in support of RTLP.

SL Viewer Update

Avatar Layers Project Viewer

Vir Linden’s work on a new global limit for system layer clothing was released as a project viewer, version 3.7.26.299805. With this viewer, a user can wear any combination of clothing layers (wearables), up to a maximum of 60, rather than being limited to (in general, and as with the official viewer) to a maximum of 5 items per layer type. Note that these changes do not apply to body part wearables (skin, shape, hair, eyes), for which the limit is still one of each, and do not affect attachments, for which the limit is still 38 total.

[07:18] There is already an update in the pipe for this viewer, which should be appearing next week.

Camera Positioning / Handling

[05:12] While there are no specific details as yet, the lab is hoping to put some work into improving camera positioning and handling in the not too distant future, in the hope of removing various glitches and issues.

Build Tools Viewer

[05:54] There have been a few fixes added to this viewer (currently version 3.7.26.299443), so a further update to the release candidate version is with the Lab’s QA team and should be appearing in week #14 (week commencing Monday, March 30th).

Maintenance Release Viewer

[06:29] Currently at version 3.7.26.299845, the latest Maintenance release viewer has a range of issues, many of which have hopefully been addressed with a series of fixes, so an update to that viewer is also with the Lab’s QA team. However, given the scope of the updates, it is proving a little harder to pass the QA process.

Experience Tools Viewer

[06:50] The Experience Keys / Tools viewer (currently version 3.8.0.299338) is being merged-up with the latest release version of the viewer code (version 3.7.26.299635). The updated version should also be appearing (again as an RC) in week #14.

Viewer Code

[17:27 – 19:50] There is an interesting discussion on the viewer code which, for anyone interested in how the viewer has developed over the years, and how much of it dates back some 14 years.

Viewer-Managed Marketplace

[00:00] There was a pile-on test of the new Viewer-Managed Marketplace capability on Aditi in week #12, and Brooke Linden was at the TPV Developer meeting to provide feedback. The pile-on test did not reveal any significant issues in terms of performance.

However, there is still a viewer / simulator / marketplace  communications issue which has to be resolved, which may take another couple of weeks to fix. After that, there are two grid deployments which need to take place: one for the VMM code itself, and one for updates to the Advanced Inventory System (AIS), so it is unlikely VMM will be fully deployed within the next month to two month, and the project viewer (currently version 3.7.25.298865) is unlikely to progress through a release candidate to release status until after the server components have been deployed.

Group Chat

Simon Linden has been working on significant improvements to the group chat service
Simon Linden has been working on significant improvements to the group chat service

[07:32] Simon Linden has been continuing to work on the group chat code, and all of his current updates should have been deployed to the back-end group chat servers. A broad consensus is that the issues which recently occurred as a result of some changes have been reversed, and that the group chat service as a whole is now running a lot better, both in terms of the early performance improvements Simon made, and with regards to the overall stability of the service and the servers.

[08:24] There is a further round of updating in the planning, but these require a platform upgrade to be carried out for the group chat service first. Therefore, unless unless the latest set of updates deployed by the Lab start to show issues, the engineering team will be switching focus for the immediate future, and will return to working on group chat once the necessary upgrade work has been completed.

Experience Keys  / Tools

[09:20] One of the items the engineering team want to focus on in particular is Experiences, and getting the remaining back-end issues sorted out so that Experiences can be properly deployed.

Voice Updates

[09:59] There will be a further round of voice updates which are expected to appear in a project viewer “shortly”. They include (but are not limited to) things like general code clean-up to prevent unnecessary list loading, removal of media messaging in person-to-person calls (which has never worked), fixes for issues related to microphone volume and improvements to the microphone test so that you can now hear yourself when testing your microphone, and improvements for hot swapping microphones / headsets.

[13:58] There is some confusion over whether or not a fix to voice designed to prevent someone’s voice channel being “left behind” when teleporting between regions has actually worked. It had been thought that the fix for this had been deployed in later 2014. However, bug reports are still being made still reporting issues (see BUG-8543 and STORM-2109), prompting the Lab to re-examine the status of the fix.

[19:54] Voice package updates from Vivox are also expected to be forthcoming in the future as well.

Restore To Last Position (RTLP)

Oz Linden - keeping an eye on feedback through the Firestorm blog on "restore to last position"
Oz Linden – keeping an eye on feedback through the Firestorm blog on “restore to last position”

[21:08] There have been around 400 responses to the Firestorm call for feedback on how people use the Restore To Last Position functionality found in some TPVs. As I’ve previously reported, the Lab had been considering deprecating the server-side message RTLP uses as an overall part of on-going work to reduce the amount of inventory loss issues (real or perceived) which can occur.

Firestorm’s call is helping the Lab to better understand how, as faulty as it might be, RTLP does fulfil a range of useful / valid use cases. Commenting on the fact the he has been reading through the feedback, Oz Linden said:

[21:49] Well, I understand that there are user scenarios that need to be addressed and need to be better supported. Whether the existing feature is the way to do that or not, I still consider to be an open question. I do want to take those use cases and work back through that process [of determining how best to serve them].

So the Lab still isn’t going to do anything “quickly” either way on RTLP, and people needn’t worry about RTLP vanishing / breaking “suddenly”.

In the meantime, they are working on other changes intended to address various rezzing failure situations. This work is more server-side focused, although it may be a while before updates appear on the grid as the exact nature of the updates is still being determined.

[23:42] Oz also again thanked everyone who responded to the Lab’s call for feedback on inventory losses in general, defining the feedback as “really, really useful”.
