Server Deployments

There are no planned deployments for the week. However, all servers on the three RC regions will be subject to a rolling restart. This is in accordance with the Lab’s new policy of restarting channels every fortnight, whether or not there is an associated deployment. As the Main (SLS) channel underwent a restart on Tuesday, January third, server on this channel were not restarted this week.

SL Viewer

Project Alex Ivy

The 64-bit versions of the official viewer arrived in project viewer form on Tuesday, January 10th, under the code name Project Alex Ivy – which I take to be a reference to 64 (LXIV being 64 in Roman numerals, hence aLeX IVy).

The viewer, version 5.1.0.501863, has been built using the newly updated and upgraded libraries and build process the Lab has been putting together, which will also be used for 32-bit Windows builds. Thus, the project viewer is available in three flavours:

  • 64-bit Mac
  • 64-bit Windows
  • 32-bit Windows.

There is no Linux viewer as yet, but the Lab has indicated it is their intention to provide one, although TPVs and open-source contributors are likely to still be asked to help with its ongoing support.

Additionally, the following points, as specified in the release notes, should be underlined (although please ensure you read the release notes in full if you intend to try this viewer:

  • The Mac build has several known limitations:
    • There is currently no Mac Havok build,so pathfinding paths cannot be visualised, and it may not be possible to upload mesh assets.
    • Video media using QuickTime does not play.
  • The 64-bit version will not run on Windows 10 systems with Intel HD 2000/3000 GPUs and may not run on other systems that do not have GPUs explicitly supporting Windows 10.

These shortfalls will be addressed as the viewer progresses through the project and release candidate phases to release status in the next weeks / months. Once released, it will signal the end of the 32-bit MAC version of the viewer (and possibly the 32-bit Linux version). The Windows version will continue to be available as a 32-bit build as well as having the new 64-build available.

Also, note that this viewer doesn’t include any functional updates / changes to the existing viewer.

Remaining Viewers Pipelines

Outside of the 64-bit project viewer, the various viewer pipelines remain as my last SL project update:

  • Current Release version: 5.0.0.321958, dated December 1st, promoted December 5th – formerly the Project Bento RC viewer
  • Maintenance RC viewer, version 5.0.1.322513, dated December 21st – some 42 fixes and improvements + Bento support
  • 360-degree snapshot project viewer, version 4.1.3.321712, dated November 23rd – ability to take 360-degree panoramic images – hands-on review
  • Obsolete platform viewer version 3.7.28.300847, dated May 8, 2015 – provided for users on Windows XP and OS X versions below 10.7.

Monday Outage

On Monday, January 9th, many users were hit with significant issues, with many finding themselves unable to log-in, or being disconnected from the simulators and unable to log back in. On Tuesday, January 10th, April Linden from the Ops team posted another of her excellent post-mortem blog posts on what happened, and I recommend it as a worthwhile and informative read.

In essence a failure within a third-party provider used by the Lab failed to trigger the expected automatic switch-over of connections for all users accessing Second Life through that provider. As a result, those users were disconnected from the service, and due to the volume of people trying to re-connect, couple (I assume with those simply trying to log in, unaware of problems) generated a backlog, forcing the Lab to bring additional log-in servers on-line.

Once again, April does an excellent job in explaining things – revealing more of the complexities of SL in the process (which, as I’ve oft said in the past, goes well beyond just the simulator servers), and also offers apologies for the Monday problems.

Server Deployments

The RC channels were re-started on December 28th, 2016, to the consternation of some on the Server thread of the technology forum as there was no accompanying update. A rolling restart of the Main (SLS) occurred on Tuesday, January 3rd, 2017, again with further consternation on the thread.

However, as a quick check through the viewer can reveal, both of these operations were simply restarts to keep things running (reasonably) smoothly, as shown by the server version numbers remaining unchanged when viewed in the viewer (Help > About viewer).

No restart is anticipated for the RC channels on Wednesday, January 4th, given they were restarted at the end of December. The usual run of deployments + restarts are expected to resume in week #2 (week commencing Monday, January 9th) with the three RC channels.

SL Viewer

With the holiday break, there has been no movement with the official viewer, with four currently occupying the various pipelines:

  • Current Release version: 5.0.0.321958, dated December 1st, promoted December 5th – formerly the Project Bento RC viewer
  • Maintenance RC viewer, version 5.0.1.322513, dated December 21st – some 42 fixes and improvements + Bento support
  • 360-degree snapshot project viewer, version 4.1.3.321712, dated November 23rd – ability to take 360-degree panoramic images – hands-on review
  • Obsolete platform viewer version 3.7.28.300847, dated May 8, 2015 – provided for users on Windows XP and OS X versions below 10.7.

It had been indicated that the Lab might get a project version of their 64-bit viewer out prior to the holiday break, but this proved not to be the case.

 

A look at Second Life updates in 2016

A Painter's Link, Salomon Beach; Inara Pey, December 2016, on Flickr A Painter’s Link, Salomon Beachblog post

Each week through the year, I try to get to as many in-world and other meetings held by the Lab to keep an eye on technical developments and updates which are in the works for the viewer and the simulator, relaying the notable items via my SL project updates. As such, I thought it might be interesting to look back at some of the technical changes and updates have come our way in 2016.

The Big Ones

There were obviously a number of fairly high-level updates which came our way, notably Project Bento, which gave us a lot of new bones and attachment points specifically for mesh avatars to make them more flexible and easier to animate. There’s a whole story behind that project which perhaps hasn’t been told in full, so expect to read more from me on it in the New Year 🙂 .

Then there was Avatar Complexity, or Jelly Dolls as it has been more popularly dubbed (initially by Whirly Fizzle after it was pointed out the term “Jelly Baby”, as initially used was in fact a trademark). Avatar Complexity is designed to reduce the often high cost of avatar rendering by the viewer, thus lightening the load on computers / graphics cards which might otherwise struggle.

A longer-term hope may have been that perhaps it would encourage people to consider what they are wearing and how it may affect others, and even get content creators to think more conservatively about their creations, and seek to optimise them for rendering. Whether either of these latter points might be / already have come about is nigh-on impossible to judge.

The Viewer

Both Project Bento and Avatar Complexity involved some pretty substantial changes to the viewer – Bento to the degree it warranted a version number boost. But they weren’t the only significant changes. There were also 6 new Maintenance viewers through the year, bringing with them over 250 fixes, updates and improvements. Besides these the following notable viewer releases / updates also appeared through the year.

Graphics Presets

Alongside of Avatar Complexity we gained Graphics Presets, another useful means to help improve viewer performance by allowing users to save different graphics set-ups for the viewer. This means, for example, we can have a preset for taking photographs, with all the more taxing graphics options – shadows, lighting, longer draw distance, etc – can be enabled, then have another for, say, shopping, where all the bells and whistles aren’t required, helping to improve viewer performance – and we can quickly change between them without all that tedious mucking about in Preferences.

Graphics Presets (also in most TPVs) allows you to create and save your own graphics presets to suit different requirements, and which can be quickly loaded and used with just a couple of mouse clicks

If you are on a system which can struggle at times because you have your graphics settings tweaked a little on the high side and you’ve not experimented with Graphics Presets, you might want to give them a try.

Visual Outfits Browser

The Visual Outfits Browser brought with it the ability to have images associated with your Outfits (if you use the Outfits capability). Feedback on this seems to have been mixed. Many like it, while many, equally, ignore it (and I’m among the latter category).

HTTP Updates

The viewer received a lot of new under-the-hood HTTP updates, including the removal of  a considerable amount of deprecated and unused code, and a series of improvements for things like image, mesh and animation uploads, inventory manipulation, the Viewer Management Marketplace, LSL script compilation, Experiences management, etc.

Voice Updates

Voice has been worked on throughout 2016, with the Lab working closely with the Voice package provider, Vivox, to improve connectivity, overcome Voice quality issues, and removed many of the known exploits as possible to prevent thinks like a user in one region eavesdropping on a conversation being held in another region.

This work has involved changes to the viewer, changes to the simulator, changes to the Voice binary package supplied by Vivox (SLVoice.exe) and even changes to the Vivox servers (Voice is routed through their own servers).

LibVLC

As Apple dumped QuickTime for Windows with potential security vulnerabilities unpatched, The Lab adopted LibVLC for media handling in the Windows viewer (and will be moving to it win the Mac and Linux viewers when their have released their 64-bit viewers).  The move overcomes most issues in trying to play back media in-world, however, licensing around the Advanced Audio Coding and MP3 formats, and the way things are packaged with LibVLC might leave TPVs with a headache or two.

Inventory Handling

Aura Linden worked on removing deprecated and unused UDP inventory messaging mechanisms from the viewer. This work is to be followed by the removal of back-end support for the removed message channels, and further viewer-side work on rationalising and refactoring the code handling inventory operations.

360 Snapshot Viewer

Whilst still only a project viewer, the 360 snapshot  viewer is part of a viewer / simulator project to bring 360-dgree photography to Second Life.

Linux

One unpopular move was the announcement concerning Linux development going forward (although the Lab will be building a 64-bit Linux viewer).

The Simulator and Servers

The simulator software continued through its weekly deployments throughout the year, added bug fixes, security updates, feature requests and more each month. Listing everything that happened here would rapidly turn this article into a TL;DR. However, as well as the continued deployment of simulator code updates, 2016 saw the mechanism and tools used to build the simulator undergo update, as was (/is) the underpinning server operating system running the simulators.

Support for larger animation files was introduced, with uploads increased from 120Kb to 250Kb.

Group bans finally got a tweak so that those banned from a group whilst active in group chat would finally get booted from the group chat session as well.

Experiences got a new scripted sit capability, code-named Project Espeon.

And, of course, we have the increases to Land Capacity (or LI or prims, however you like to think of it).

Aditi Inventory Syncing

A new process for syncing inventory between Agni (the Main grid) and Aditi (the beta grid) was introduced, eliminating the need for users wishing to have their Agni inventory fully replicated on Aditi having to change their SL password and then wait between 24 and 48 hours (sometimes longer) for their Aditi inventory to be synced with Agni. Under the new system, a process automatically merges a copy of users’ Agni inventories with their Aditi inventory based on their last log-in to the beta grid.

There were some teething problems with the new system when first introduced (and some people report there may still be hiccups), but on the whole the new process is a lot smoother than the old.

Web Services: TLS 1.2 and More

The Lab made the switch to TLS 1.2, which had the potential to impact people’s ability to buy L$ via the LindeX / through a browser and / or add payment info to their account if they were not using a suitable viewer or web browser.

There were also numerous changes to various web properties, including updates to the SL Marketplace, the retirement of SLurl.com, various security and infrastructure updates

Grid Status Page

The Grid Status page moved to a new provider and was overhauled to be hopefully more informative, and have a faster means of update.

 2017 Expectations

The lab plays their cards close to their chests when talking about upcoming changes / updates / improvements to Second Life, but here’s a (short) list of some of the things we can reasonably expect to see in 2017:

  • 64-bit versions of the official viewer (Windows, Mac and Linux).
  • Possible changes / tweaks to the avatar / object complexity calculations made by the viewer, such as it being able to more easily determine those avatars in its field of view it should not attempt to fully render (rather than waiting on information from the simulator to make that determination).
  • Further updates to the viewer build tools (e.g. VS 2015 for Windows).
  • Progress on the 360 snapshot viewer.
  • Further work cleaning-up and rationalising the viewer code.
  • Voice updates for both the server and the viewer.
  • Continued server deployments and improvements 🙂 .

SL project updates 2016 51: server, simulator OS update

Server Deployment

While the No Change window was supposed to have come into operation on Friday, December 16th, there was indeed a deployment to the Main (SLS) channel on Tuesday, December 20th. It comprised the same server maintenance package as deployed to the RC channel in week #50, comprising internal logging changes.

The deployment means that all of the server channels on the main grid (Agni) are now running the same simulator version. As there are no planned deployments to the RC channels, all four channels should remain on this release until deployments resume after the holiday period.

SL Viewer

We might see a 64-bit project viewer appear during the week. However, at the time of writing,  the list of viewers in the various pipelines remains as:

  • Current Release version: 5.0.0.321958, dated December 1st, promoted December 5th – formerly the Project Bento RC viewer.
  • Release channel cohorts:
    • Maintenance RC viewer, version 5.0.1.322219, dated December 9th – some 42 fixes and improvements + Bento support
  • Project viewers:
    • 360-degree snapshot viewer, version 4.1.3.321712 dated November 23rd – ability to take 360-degree panoramic images – hands-on review
  • Obsolete platform viewer version 3.7.28.300847 dated May 8, 2015 – provided for users on Windows XP and OS X versions below 10.7.

Bento Support

With the release of Kokua for Second Life 5.0.0 and RLV 2.9.21 (see my article here), the following currently maintained viewers all have Bento support: Black Dragon, Catznip, Cool VL, Firestorm, Kokua for Second Life, Restrained Love. Alchemy is expected to update to include Bento “soon” and UKanDo is still awaiting a complete overhaul.

In terms of clients with 3D viewing capabilities, Radegast has been updated to support Bento, but the update is pending release. Lumiya for Android will have Bento support added “soon” (Lumiya 3.3 with Voice support released on Sunday, December 18th, and my review is available here).

Simulator OS Update

The Lab is in the process of updating the operating system on the simulator servers. At the moment the new OS version is installed on a number of regions on Aditi (the beta grid), including: Fire Ants 1, Fire Ants 2, Grasmere, Oak Forest, and Twilight Shores, not all of which are open to the public.

“This is one of those ‘features’ that might perform a bit better, but otherwise is a success if it behaves exactly like our current servers,” Simon Linden said at the Simulator User Group meeting on Tuesday, December 20th.

“We’re in the starting process of testing things. We have a lot of testing to do. [We’re] updating from an old version of Linux to a not-so-old version of Linux,” April Linden added. “Just to keep things moving. All the usual reasons. Performance updates, security, etc.”

Second Life hits a lot of low-level server code hard, including networking, memory and multi-processing. The overall hope is to have the newer revisions of the operating system will improve these. Expect this work to reach Agni in early 2017.

Group Chat

Group chat was long a bane of Second Life. In 2014/15 however, the Lab put a considerable amount of work into improving things, although some issues remain. One of these is that if an individual role outside of the default “Everyone” has a very high number of group members assigned to it (e.g. several thousand), it can dramatically impact things like group chat performance and can prevent the members’ list loading. One solution might be to delete the role (converting those in it to Everyone).

Server Deployments

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

  • On Tuesday, December 13th, the Main (SLS) channel received the same server maintenance package, as deployed to the RC channels in week #49. This includes the following feature requests:
    • BUG-6377 – llGetObjectDetails(id,[OBJECT_ATTACHED_SLOTS_AVAILABLE]) – Returns a value that is number of attachment slots allowed by the server minus the number of attachments worn by avatar. Returns 0 if avatar is not in the same region or if UUID is not an agent.
    • BUG-40871 – llGetEnv() constant “region_object_bonus” – returns the object bonus set for a region.
  • On Wednesday, December 14th, all three RC channels should receive the same new server maintenance package, comprising improved internal server logging.

SL Viewer

The Maintenance RC viewer updated to version 5.0.1.322219, bringing it to parity with the current release viewer, incorporating the Bento updates. This leaves the remaining viewers in the pipelines unchanged from week #48:

  • 360-degree snapshot viewer, version 4.1.3.321712, dated November 23rd.
  • 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.

No Change Window

The Christmas and New Year 2016/17 No Change window comes into effect from Friday, December 16th. This means there will be no further server deployments and no further official viewer promotions after that date, through until Monday, January 2nd, 2017.

Issues

Mesh and Texture Rezzing

As noted in my week #49 update, people have been noticing increased delays in object mesh and texture rezzing, with fingers being pointed at the Lab’s CDN supplier(s).  The issues are continuing for some, while for others they appear to have cleared up. It’s still not obvious if it is a potential LL / CDN issue or a network problem in general.

As Simon Linden said in the meeting, the problems have been seen by the Lab, but are proving to be intermittent and hard to pin down. The problem also seems to manifest differently for people: some report very slow texture rendering, other report textures load and render fine, but mesh items are prone to failing to fully render, others report a mix of the two.

Region Crossings

Region crossings have been widely reported as increasing again – including avatars being dumped at 0,0,0 (again). Some are reporting the issue as cumulative: the more regions they cross, the greater the likelihood they’ll encounter a serious issue (becoming unseated, return of vehicle, forced log-out). The usual advice is being circulated – reduce script load, handle crossings with caution, etc. However, the Lab are again aware of the uptick, but have not come to any specific conclusion on the cause.

The avatar appearing at a region’s 0,0,0 co-ordinates appears to be linked to connection problems and / or UDP packet loss (usually the first packet) resulting in messages arriving in the wrong order and the viewer and simulator falling out of synch with one another.

With both the rendering issues and the region crossing issues, fingers have been directed at the increased land impact allowances. This may be a case of post hoc, ergo propter hoc. In particular, it has been claimed that region crossings “became” bad after the mainland LI allowance increase, although people were reporting issues before the LI increase took place.

Appearance Issues / Bake Fails

Some are finding their avatar is failing to render in their view (bake fail) when logging-in. Changing outfits, camming away / back to your avatar may fix this, or a re-log. In extreme cases reverting to the default Character Test avatars may be required, or deleting and recreating the affected avatar appearance folder on your hard drive.

Rider Linden is looking into the problem, and believes it may be due to a missed inventory fetch at log-in, leaving the viewer thinking you’re missing a critical part of your appearance (e.g. your shape), but he is not 100% certain at this point in time.

2016 SL project updates 49/1: server, viewer, issues

La Digue du Braek, Muppets Island; Inara Pey, December 2016, on Flickr La Digue du Braek, Muppets Islandblog post

Server Deployments

On Tuesday, December 6th, the Main (SLS) channel was updated with the same server maintenance package deployed to the three RC channels, comprising internal simulator changes.

On Wednesday, December 7th, the three RC channels will received the same new server maintenance package, which includes the following feature requests:

  • BUG-6377 – llGetObjectDetails(id,[OBJECT_ATTACHED_SLOTS_AVAILABLE]) – Returns a value that is number of attachment slots allowed by the server minus the number of attachments worn by avatar. Returns 0 if avatar is not in the same region or if UUID is not an agent.
  • BUG-40871 – llGetEnv() constant “region_object_bonus” – returns the object bonus set for a region.

SL Viewer

On Monday, December 5th, the Project Bento viewer, version 5.0.0.321958, was promoted to de facto release status. See the official blog post here and my post here.

This leaves the current viewer pipelines looking as follows:

  • RC viewers:
    • Maintenance RC viewer, version 4.1.3.321792, dated November 30th – some 42 fixes and improvements
  • Project viewers:
    • 360-degree snapshot viewer, version 4.1.3.321712 dated November 23rd – ability to take 360-degree panoramic images – hands-on review
  • Obsolete platform viewer, version 3.7.28.300847, dated May 8, 2015 – provided for users on Windows XP and OS X versions below 10.7.

Other Items

Mesh and Texture Rezzing

People have been noticing increased delays in object mesh and texture rezzing, with fingers being pointed at the Lab’s CDN supplier(s).  Raised at the Simulator User Group meeting, it prompted Simon Linden to comment it could be a CDN issue, and re request was passed for the Lab to have a poke around at things.

Duplicated No Copy Items

Raised a couple of weeks ago, this is an issue where region crashes are being exploited to create duplicates of No Copy items (i.e. the duplication is happening server-side, rather than the objects simply being copied using a viewer, making them indistinguishable from the original), with the duplicated item – mostly obtained through gachas – then being put up for sale on the Marketplace.

The Lab is continuing to look at the problem, but as yet, no answer / solution has been identified.
