Server Deployments Week 16

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

On Tuesday, April 14th the Main (SLS) channel was updated with the server maintenance package previously deployed to all three RC channels. This comprises a crash fix, minor CDN configuration updates and an internal server configuration update.

On Wednesday, April 15th, all three RC channels should receive a new server maintenance package, 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.

SL Viewer Updates

The Maintenance RC viewer, version 3.7.27.300636 was promoted to the de facto release viewer on April 13th. The viewer contains multiple fixes and improvements, as detailed in the release notes.

This release also includes the fix for the URI parsing error, which was originally issued in the HeatWave RC viewer (formally version 3.7.27.300424, which has been withdrawn from the release channel as a result.

Webkit Replacement, Flash and Quicktime

As I’ve reported on a number of occasions, Webkit is a third-party library which has been used within the viewer for a number of media-related tasks (powering the built-in web browser, displaying profiles, and is used with MOAP  and many in-world TVs). However, it has been something of a problem for the Lab,  with out-of-date libraries and other issues.

Because of this, there is a project under-way in the Lab to replace webkit with the Chrome Embedded Framework (CEF). Work on this within the Lab has been progressing, and they now have CEF working with the windows version of the viewer, and are now focusing on getting it working on the Mac version.  There are no plans to release a test or project viewer with CEF support until it is running on both platforms (it is thought that Linux will be able to use the Mac version).

Avatar Complexity (RenderAutoMute Functions)

The new rendering controls will allow users to set a level above which avatars will be rendered as a solid colour
The new rendering controls will allow users to set a level above which avatars will be rendered as a solid colour “jelly baby”

In week #47. 2014, I reported on how the Lab is working to give greater control to users over how other avatars are rendered in their own view.

Avatars can frequently have very high render costs associated with them which, even in modestly populated areas, can have a detrimental impact on viewer performance on lower specification hardware.

The idea with the new, still-to-be-released functionality is that users will be able to define a render weight for their viewer when drawing avatars. Any avatar that exceeds this limit will be rendered as a solid colour “imposter”, regardless as to how near / far they are from a person’s viewpoint.  Thus, the rendering load is reduced, improving overall performance.  Because of the solid colour aspect of the avatars when rendered in this way, they were somewhat quickly dubbed “Jelly Babies” after the sweets of that name. note they are only rendered like this in your own view, it doesn’t affect how others see them.

This work has been going on for some time, now, and is approaching maturity. Commenting on it at the Open-source Developer’s meeting on Monday, April 12th, Oz Linden indicated that things are currently waiting server side updates. Included in the functionality is a means by which someone can see the number of other people who are rendering their avatar as a “jelly baby”.

The capability can actually be experimented with at the moment, although it is a case of trial and error until the new UI controls are added to the viewer. Should you wish to try, go to Advanced > Debug Settings and type-in RenderAutoMute. This will list a series of options, of which RENDERAUTOMUTEFUNCTIONS and RENDERAUTOMUTERENDERWEIGHTLIMIT are the two you need:

  • RENDERAUTOMUTEFUNCTIONS is essentially the “on / off” option for enabling the other options, and must be set to 7 in order for any of them to work
  • RENDERAUTOMUTERENDERWEIGHTLIMIT is the function that determines how avatars are rendered. Try starting with a value of around 100,000 and experimenting from there.

Group Chat

BUG-9020 reports issues with people being unable to see anything typed in certain group chats they belong to – either their own messages, or anything typed by anyone else. The problem appears to possibly be more widespread than the report indicates – if you are experiencing a problem, please consider adding the details to the report: the specific groups, etc., and specific issues. The Lab is currently looking into this and checking through the additional logging / diagnostic tools they’ve added to the group chat services to see if anything is showing-up as causing the problem.

Other Items

In-viewer Translation Tool Fix

As noted in my week #12 update, the built-in viewer translation tools are now pretty much broken (Google and Bing). Nalates Urriah filed a bug report on the Bing situation recently (see: BUG-8794 “The Bing API used by the viewer is depreciated [sic]”).

Commenting on the situation at the Open-source Developer’s meeting on Monday, April 13th, Cinder Roxley indicated that the Alchemy TPV team are working to get the viewer translation tool working again, although there is currently no ETA on this. The fix is liable to appear in the Alchemy viewer, but the code will be contributed to Linden Lab.

Forum Log-in Issue

As noted in BUG-8953, there is currently an issue with signing-in to the the SL forums, and staying logged-in. the problems are broadly two-fold. In short, people are finding they are being randomly logged-out of the forums for no apparent reason, or are being redirected to the top-level community page when logging-in, rather than being redirected back to the page in the forums they had displayed prior to the log-in request being displayed (e.g. when replying to a post).

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).

Don#t forget you can plunge into learning about SL’s extensive merfolk and undersea community this week, thanks to the folk at Fanci’s Deep and the Safe Waters Foundation. There’s undersea tours, dances, dolphin rides, shopping opportunities, freebies and a whole lot more. You can even visit the mer beach and fun fair (above)! To find out more, read the blog post on the event, which runs through until April 11th

Server Deployments Week 15

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 will receive the server maintenance update previously deployed to the three RC channels. This is primarily focused on trying to prevent  inventory loss issues, and sees UDP inventory messaging deprecated (see HTTP Inventory, below, for more important information)
  • On Wednesday, April 8th all three RC channels should receive a new server maintenance package comprising:
    • A fix for a server crash when rezzing an object
    • A minor change for CDN configuration
    • Adjusted internal server configuration.

SL Viewer Updates

A new release candidate viewer was released towards the end of last week. The HeatWave viewer, version 3.7.27.300424. This is essentially the maintenance RC viewer with an additional URI parser fix to prevent a viewer crash bug, but has retained a project name to differentiate the two RCs from one another.

 HTTP Inventory

With the Tuesday deployment (noted above), the main grid now only supports HTTP Inventory fetching. This means you must have the HTTP Inventory option enabled in the viewer (it can be found under the Develop(er) menu).

Should you disable it for any reason, you will encounter two issues:

  • Your avatar will not render, but will remain a cloud
  • Should you refresh your inventory for any reason (clear cache), your viewer will never complete the process of inventory fetching.

Unfortunately, and coincidentally, the Main channel deployment on Tuesday, April 7th came at a time when asset server / inventory issues were being experienced across the grid, and inventory database maintenance was carried out as a result.

Note that from Tuesday, April 6th, you must ensure HTTP Inventory is enabled in the Develop menu (sometimes called the Developer menu in TPVs) in order to help avoid inventory and / or avatar rendering problems
Note that from Tuesday, April 6th, you must ensure HTTP Inventory is enabled in the Develop menu (sometimes called the Developer menu in TPVs) in order to help avoid inventory and / or avatar rendering problems

These issues and the maintenance may have masked any problems some people may have been having purely as a result of HTTP Inventory being disabled in their viewer.

Therefore, if you are encountering problems with your avatar remaining a cloud, or your inventory failing to load, please try the following steps to see if they resolve your situation:

  1. Make sure you have the Develop(er) menu enabled in your menu bar at the top of the viewer. Press CTRL-ALT-Q if you cannot see it.
  2. Click on Develop(er) to list the menu options.
  3. Make sure there is a tick in front of the HTTP Inventory option.
  4. If HTTP Inventory does not have a tick in front of it, then it is disabled. Click on it to enable it (and display the tick).
  5. Closed the Develop menu and re-log.
  6. Hopefully, following your re-log, your avatar will render / your inventory load properly.

UDP Inventory Messaging Deprecated

The reason for this is that the Lab has now deprecated the “old” method of inventory messaging (referred to as UDP messaging). However, if you disable the HTTP Inventory option in your viewer, the viewer will still attempt to use the “old” method, and thus you’ll have problems.

There are plans in hand for the Lab to remove the HTTP Inventory option from the viewer, and some TPVs may opt to remove it ahead of any update from the Lab. Until that time, it is essential you keep the option enabled to assist with the smooth functioning of your inventory.

Experience Keys / Tools

Not a lot to report on this project. Simon Linden has been working on the Key Value (KVP) database store used by Experiences. This work appears to be related to the Lab working to ensure the when deployed Experience Keys / Tools can be properly scaled to meet the anticipated demand for them. Commenting in general terms on the work, Oz Linden said during the Simulator User Group meeting on Tuesday, April 7th, “if we are as successful as we’d like to be with Experiences being adopted, it would run into problems. So we’re trying to solve them before we get to that point.”

Server Deployments Week 14 – Recap

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

  • There was no deployment to the Main SLS channel on Tuesday, March 31st, due to the inventory issues arising from the week #13 RC deployment – see my update here for details.
  • On Wednesday, April 1st, all three RCs received the same update to the current server maintenance package to fix the issues with Trash failing to purge in non-AIS v3 viewers (see BUG-8877. and my coverage of the recent issues here). Those suffering from inventory fetch failures on RC regions are advised to re-enable HTTP Inventory in their viewers, if disabled (found under the Develop menu).

SL Viewer

Wednesday, April 1st saw the release of the Project BigBird viewer (yes, seriously!), version 3.7.27.300377, which contains the various fixes for attachment issues which the Vir Linden has been working on. Specific fixes offered are listed as (note the MAINT designations are for the Lab’s internal JIRA, and thus non-viewable):

  • MAINT-4351 HUDs and attachments intermittently and randomly detach after teleports, sometimes reattaching on their own shortly after, sometimes staying detached completely, or showing as “worn on Invalid Attachment Point” while still detached
  • MAINT-4653 [Attachment-RC] When using “Add” or “Attach to” to attach multiple attachments at the same time, some attachments fall off and some get attached to the wrong attachment point
  • MAINT-4917 Attaching multiple objects generates multiple bake requests
  • MAINT-4918 Removing multiple attachments generates redundant detach requests
  • MAINT-4919 Attempting to wear an outfit with more than 40 attachments will fail

UDP Paths: HTTP Inventory, Textures and More

As noted at the top of this report, the week #13 RC deployments have been causing some inventory-related issues, one of which –  the Trash purging problem – has been fixed with this week’s RC RC deployment.

The second issue  – failures in inventory fetching following clearing cache on RCs regions – has been caused by a combination of the Lab deprecating the UDP message path for inventory updates and users having the HTTP Inventory option in the viewer (found under the Develop menu – CTRL-ALT-Q) disabled (unchecked).

Given this path has been deprecated, it is essential you keep HTTP Inventory enabled (the Lab will be removing the option from the Develop menu in the future to prevent it being unwittingly disabled).

Speaking at the Server Beta Meeting on Thursday, April 2nd, Oz Linden indicated that the Lab would be taking steps in the future to deprecate UDP messaging is “high on the list” for being deprecated in the future, given that textures have now moved to the CDN.

The CDN and Switching Further Services

While discussing the issue of UDP messaging, Oz again re-iterated the desire to pivot things like fetching animations and sounds away from UDP and onto HTTP, with the aim of provisioning them through the CDN, further lifting the load the simulators currently carry. However, he caveated this with two important points:

  • While this is something he’d like to see done, and is in the plans for SL’s future, the work hasn’t actually be scheduled yet, must less started; therefore it is not something that will be happening in the short-term (or perhaps even the medium term)
  • The Lab is working on a further round of CDN improvements – again, no time scale is available for their implementation – but there won’t be any additions to the data delivered via the CDN until after such improvements have been deployed.

One aspect here is that, in terms of the simulator load and in terms of the vast majority of users, the switch-over to avatar, mesh and texture data to CDN-based services has been a success for the Lab. However, as we’ve also seen, it has resulted in issues for some users, up to and including what is a degraded service due to the actions of at least one ISP.  While the latter is not something the Lab or their CDN provider can directly tackle, it does point to the fact that while off-loading the heavy lifting from the Lab’s servers can make for improvements, it can affect users in other ways.

Hence why the Lab is being cautious in approach, and is continuing to work with its CDN providers to try to improve the service as far as can be done, in the hope of reducing the number of ways in which users might find SL a poorer experience as a result of the CDN implementation. However, exactly what can be achieved and issues mitigated, remains to be seen.

In the meantime, as as per part 1 of this week’s update, if you do feel mesh and texture rendering isn’t what it once was, try following Monty Linden’s interim ideas  for easing things.

SL project updates week 14/1: server and viewer updates, misc items

Posted on by Inara Pey

Server Deployments

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

There was no deployment to the Main SLS channel on Tuesday, March 31st, due to the inventory issues arising from the week #13 RC deployment – see my update here for details.

On Wednesday, April 1st, all three RCs will receive the same update to the current server maintenance package. This update is specifically aimed at correcting the trash purging issue reported with BUG-8877. However, the fix does not address the issue of inventory fetching hanging if HTTP Inventory has been disabled within the viewer.

This is because the Lab regards UDP inventory fetching as a deprecated protocol path, as indicated by the release notes, and non-HTTP based inventory fetching is now being phased out. As such, it is anticipated the option to disable HTTP Inventory within the viewer is likely to be hidden / removed at some point in the future.

SL Viewer Updates

The Tools update RC viewer updates to version 3.7.27.300242 on Monday, March 30th, bringing it into line with the current release viewer (3.7.26 with Avatar Hover Height).

The Maintenance RC viewer updated to version 3.7.27.300323 on Tuesday, March 31st. also bringing it into line with the current release viewer,  and includes fixes for many of the bugs and issues encountered with the initial release of the RC.

Other Items

Diagonal Region Rendering Issues

A fair while ago now (late 2012 / early 2013 in fact), I reported on issues that had been noted with regions seeming to be “missing” when seen from other regions.The problem was originally reported in SVC-8130, which is still marked as “unresolved”, and it had been hoped that fix for SVC-8019 would address the problem as well as dealing with other issues. However, the problem has continued intermittently ever since, with numerous issues marked as duplicates of SVC-8130 being reported, with the issue most recently being seen when looking at regions diagonally opposite Brocade on the Mainland.

The return of the missing regions issue (if it ever really went away): looking north-east from Brocade towards where Mullein isn't on the Mainland. Not, as well, the region kitty-corner beyond Mullein is also absent the view, although both appear on the map
The return of the missing regions issue (if it ever really went away): looking north-east from Brocade towards where Mullein isn’t on the Mainland. Not, as well, the region kitty-corner beyond Mullein is also absent the view, although both appear on the map

The problems are regarded as handshaking / communications issues between region, and are generally resolved through a region restart; although understandably, some holding regions on Mainland are reluctant to request a restart as this can affect multiple other region as well.

Multiple Calling Cards

Most of us are familiar with calling cards in the viewer. They can be obtained by friending someone, or by someone giving you their card (or you giving them your card, and are useful for things like  opening people’s profiles from inventory (particularly handy in cases where you haven’t friended someone, and so don’t have to use search to locate them), or initiating an IM conference call.

One of the many calling cards issues - spawning multiple copies of the same card (images via Jessica Lyon)
One of the many calling cards issues – spawning multiple copies of the same card (images via Jessica Lyon)

However, within v3-style viewer they can also be annoying, as they have a tendency to multiple for no readily apparent reason. People can often have a set of calling cards under the Calling Cards folder, which can be partially replicated in the Friends sub-folder, and then fully replicated in the All sub-folder beneath that, for example. Or individual cards can get spawned multiple times across one or more folders for no readily apparent reason.

The problem here is that having a high load of calling cards can generate problems logging-in to SL, where they run out of curl multihandles, causing log-in to hang or for them to disconnect on logging-in. This can usually be solved through … wait for it … disabling HTTP Inventory and then logging-in and deleting them, but this may not be an option in the future (see the notes at the start of this report). Given that calling cards get re-spawned following a re-log after deletion, and can start multiplying again, Oz noted in the SUG meeting that they are now an area “worthy of some study”.

Rendering / Rezzing Failures and the CDN

In week #13 I reported on rendering / rezzing issues being experienced by some people in the Florida / Alabama region of the USA. Since that time, the Lab’s investigations through the CDN provider have suggested the the ISP in question (Mediacom) has degraded the service, possibly due to the volume of traffic coming from the CDN. This was a concern voiced early-on during the CDN implementation, but this appears to be the first time such a move has been confirmed. In the forum thread on the matter, which has seen more input on the situation, Monty Linden has offered some interim ideas that may help users experiencing problems, while also emphasising the Lab is still working with the CDN providers to further refine the service.

SL Project updates week 13/2: TPV Developer meeting – HTTP, VMM and more

Posted on by Inara Pey

Matoluta Sanctuary, Sartre; Inara Pey, March 2015, on Flickr Matoluta Sanctuary (Flickr) – blog post

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”.
