Server Deployments – Week 4 Recap

  • There was no Main (SLS) channel deployment during the week
  • On Thursday, January 22nd, the RC channels were updated as follows:
    • LeTigre and Magnum received the same server maintenance package which included a fix for BUG-8223, introduced to all three RC channels in the week #3 deployment
    • BlueSteel received a server maintenance package which contained the same fix for BUG-8223 and also support for the new Avatar Hover Height capability

SL Viewer – Avatar Hover Height

The Avatar Hover Height project viewer was released on Wednesday, January 21st, however, an issue with the SL wiki means that it currently cannot be reached via the Alternate Viewers wiki page, which is currently showing an out-of-date listing. Those wishing to download the viewer can do so from here.

For details on Avatar Hover Height in general, please refer to my overview.

SL Wiki

The ability for users to edit SL wiki pages was re-enabled on Thursday, January 22nd, after an extended period in which they were only editable by Lab personnel. However, whether the two are connected or not, but subsequent to the wiki being opened for editing, a number of pages appeared to revert to earlier versions or became inaccessible (e.g. the Alternate Viewers wiki page reverted to a version from late December 2014, while the pages for the RC channel release notes were replaced by blank pages).

The Lab is obviously aware of the issue, and looking into it.

CDN News

The Lab has been / is testing an additional CDN provider (to Highwinds, whom they currently use). It’s not clear where the testing is going, and when asked about it at the Server Beta User Group (SBUG) meeting on Thursday January 22nd, Simon linden could only say, “it was going to allow a lot more flexibility so we could have different regions on different CDNs … or something similar.   It might have been different areas of the world on different CDNs.”

Doubtless, if / when the project moves forward, we’ll get to hear more.

And on a Lighter Note

On Monday, January 19th, people started reporting that an old group logo – Whore Couture – was appearing in place of assorted group’s usual logo, as shown in the image below, taken from BUG-8255, “Whore Couture Logo Appearing on Several Groups”, where the problem was formally reported.

BUG-8255 reported the random appearance of an old Sl brand logo - Whore couture - appearing in place of various group's usual logo
BUG-8255 reported the random appearance of an old SL brand logo – Whore couture – appearing in place of various group’s usual logo

The cause of the problem was later revealed by Soft Linden:

An engineer grabbed a random group’s image as a placeholder and put it in place of an old asset ID that was used as the default image for many groups. It was meant as a temporary measure while he was doing some other texture work. Unfortunately, he didn’t look at the image he selected and I expect he would have chosen plywood instead if he had.

The image has been removed, but it may take some time before that propagates through the CDN and viewer caches.

Don’t worry, we’re not going to let him live this down. In the mean time, we’re building some better process around this.

SL project updates 2015 week 3/2: SBUG and TPV; texture thrashing

Salt Water; Inara Pey, December 2014, on FlickrWith Love in Her Heart, Sounds of Silence (Flickr) – blog post

The following notes are taken from the Server Beta User Group (SBUG) meeting held on Thursday, January 15th, 2015, and the TPV Developer meeting held on Friday, January  16th. A video of the latter is included at the end of the article (my thanks as always to North for recording it and providing it for embedding), and any time stamp contained within the following text refer to both it and the TPV Developer meeting.

Server Deployments – Week 3 Recap

  • There was no Main (SLS) channel deployment on Tuesday, January 13th.
  • On Wednesday, January 14th, all three RC channels received the same server maintenance package comprising: a fix for BUG-8002 “Experience Tools Allowed & Blocked experiences are lost with parcel subdivision”; crash mode fixes and avatar-related region crossing code clean-up related to “clean-up and polishing” rather than to performance improvements.

SL Viewer

The Experience Tools RC viewer was updated to version 3.8.0.298091 on January 15th, bringing it up to parity with the current release viewer (the HTTP pipelining release).

[00:15] There is a new maintenance release candidate viewer that is being queued-up for the viewer release channel.

Otherwise, LL viewers remain as per the download and Alternate Viewer wiki pages, and my Current Viewer Releases page.

Tool Chain

[09:52] The Lab now has both Windows and Mac versions of the viewer building successfully using the new tool chain (which among other things, used Visual Studio 2013 for Windows and xcode 6 for Mac), and may be “pretty close” to achieving the same with Linux, although that is still to be determined.

It is anticipated that project viewers using the new build process will start to appear soon, and the process gradually be applied to RC releases and the viewer release itself, but only after full regression testing has been undertaken to try to ensure there are no hidden issues remaining.

This work does potentially make it easier for the Lab to start producing 64-bit versions of the viewer, but there are currently no detailed plans for them to start doing so at this point in time.

Experience Key Tools

[01:20] The initial release of the Experience Tools is still on the horizon, with the release candidate viewer currently the only RC in the pipeline, and which has no further viewer-side changes waiting to be implemented (which doesn’t automatically mean it will be promoted to release status next). However, the Lab is still working on some back-end issues which must be fixed before the key can be turned and the capabilities formally released.

Group Chat

[01:24] The lab is continuing to push out changes intended to make group chat more robust. While happy with the overall improvements that have been made to performance in terms of reducing the noticeable amounts of group chat lag, the problems to the chat servers locking-up every so often and requiring a restart are still being worked on. Additional testing is continuing, and Oz linden indicates that the Lab aren’t about to give up on getting to the bottom of things.

Z-offset Height Adjustment

Vir Linden
Vir Linden: working on the z-offset height solution

[02:52] This is intended to provide a means of on-the-fly adjustments to be made to an avatars height above the ground / objects and which can be used whether the avatar is standing or sitting, without the need to use the current Appearance hover slider. It will work in a manner similar to the old z-offset height adjustment found in some TPVs, and will likely comprise a slider access through the avatar right-click context menu. As well as working for individual avatars, it is thought the capability will also work against thinks like couples poseballs for dancing, although this has yet to be tested.

Vir Linden, who has been working on the project reports that the capability is now to be persistent across logins on a per-account basis (so you will be able to set it for each of your accounts, and have the viewer remember the setting for those accounts, rather than having a global setting in the viewer applicable to all accounts using that viewer).

The viewer code is about to go through internal QA testing with the Lab, and the hope is that it will appear as a project viewer during week 4 (week commencing Monday 19th January). This will be available for testing the capability on Aditi (the beta grid), where a number of regions have been set-up on channel DRTSIM-274 (notably regions Hover1 and Hover2). The project viewer will be released with notes on how to use it, and people will be invited to tes it both on these regions with the necessary server-side support and on regions without the server support (and when moving between the two), with a request that any issues found are reported via the JIRA.

Assuming no major issues are found, the server-side changes are already in the queue for release onto Agni (the main grid), and the viewer code will hopefully rapidly progress to RC status as well.

[05:21] A further server-side update which is forthcoming and will assist with this testing is the avatar attribute testing fix, about which I reported in part 1 of this update.

SL project updates 2015 week 3: server, viewer, misc

SoHo New York; Inara Pey, January 2015, on FlickrSoHo New York (Flickr) – blog post

Server Deployments – Week 3

There was no Main (SLS) channel deployment on Tuesday, January 13th. As indicated in my last update, Wednesday, January 14th should see a new server maintenance package deployed to all three RCs.  This comprises:

  • A fix for BUG-8002 “Experience Tools] Allowed & Blocked experiences are lost with parcel subdivision”.
  • Crash mode fixes
  • Code clean-up around region crossing.

The region crossing improvements are for avatars only (not vehicles), and were described by Simon Linden, speaking at the Server Beta User Group meeting on Thursday, January 8th as, “all internal and pretty minor, so please don’t get hopes up for performance improvements,” and being about “clean-up and small polishing.”

Upcoming Deployments

Avatar Attribute Testing Fix

Note: no time frame has been set for the following, so it may not appear for another few weeks.

The Lab expects to have a server-side update running soon which, while perhaps not directly noticeable to users, should make it easier for testing new avatar attributes as they are being developed by the Lab.

In summary, the current approach means that when a new avatar attribute is being tested, the attribute must be understood by each region the avatar visited; if the avatar passes through a simulator that could not identify the attribute (e.g. the attribute is only supported on a server RC channel and the avatar testing it crosses into a simulator region running on the Main channel), the value assigned to the attribute is lost, and cannot not be easily recovered (simply crossing back into the simulator region with the necessary support, for example, would not restore the attribute value).

The new update will fix this issue and will thus make it easier to test new avatar features. Potentially, one of the first of these that will benefit will be the new avatar height offset capability.

SL Viewer

The HTTP Pipelining viewer, version: 3.7.24.297623, was updated to the de facto release viewer on Tuesday,  January 13th.  This viewer provides reduced pipelined texture and mesh fetching time-out so that stalled connections fail quickly allowing earlier retry, with the time-out value changed from 150 seconds to 60 seconds.

Mesh Import Project Viewer

Chairing the Simulator User Group meeting on Tuesday, January 13th,  Oz Linden indicated that a project viewer is in the works which contains “a bunch of fixes” for mesh imports to SL. Details on precisely what issues are addressed weren’t given, but those interested might want to keep an eye on the Alternate Viewers wiki page, and I’ll of course have updates and information here as and when the viewer appears.

Webkit Replacement

Webkit is a third-party library used within the viewer for a number of tasks. For example,  it powers the built-in web browser, and is used to display profiles (unless you’re using a viewer supporting legacy profiles). It is also used with like Media on a Prim (MOAP) and many in-world televisions. However, it has been something of a problem for the Lab,  with out-of-date libraries and other issues.

During 2014, Monty Linden carried out work to improve things, but the aim has always been to replace it with the Chrome Embedded Framework (CEF).  However, this project got sidelined in the push to implement a new tool chain for viewer building, and implement a new autobuild process. This work is now very near to completion for both the Mac and Windows versions of the viewer (Linux is lagging behind, unfortunately), and the hope is that attention will again be focusing on the CEF work in the near future.

Z-offset Height Adjustment

The new "z-offset" adjustment means you'll be able to "fine tune" your avatar's height when sitting, standing, etc., in addition to general adjustments made using the hover capability
The new “z-offset” adjustment, once available, means you’ll be able to “fine tune” your avatar’s height when sitting, standing, etc., in addition to general adjustments made using the Avatar Appearance hover capability

This is intended to provide a means of on-the-fly adjustments to be made to an avatars height above the ground / objects and which can be used whether the avatar is standing or sitting, without the need to use the current Appearance hover slider. It will work in a manner similar to the old z-offset height adjustment found in some TPVs, and will likely comprise a slider access through the avatar right-click context menu.

As I’ve previously reported, Vir Linden has been working on this for a while, as a result of a direct proposal from TPV developers setting out the problem of avatar height adjustment introduced by the deployment of server-side baking and the avatar appearance “hover” parameter (which the new capability is designed to compliment, rather than replace).  The indication are that a project viewer with the new capability will be appearing “very shortly”.

Server Deployments – Week 2

There were no server deployments to either the Main (SLS) or RC channels for the week.

Upcoming Deployments

There is likely to be a server-side RC deployment in week 3 (week commencing Monday, January 12th). Details on what it will contain have yet to be finalised, however, during the Server Beta User Group (SBUG) meeting on Thursday, January 8th, Maestro Linden indicated it would contain miscellaneous fixes an improvements which will likely include:

  • A fix for BUG-8002
  • Removal support for legacy viewer-side avatar baking
  • Region crossing improvements.

The region crossing improvements are for avatars only (not vehicles), and are described by Simon Linden as, “all internal and pretty minor, so please don’t get hopes up for performance improvements,” and being about “clean-up and small polishing.”

A number of regions on Aditi are running the updates  – DRTSIM-273 – (Ahern, Bonifacio, Morris and Rizal), and a group test was carried out during the SBUG meeting with people walking / flying and TP’ing between these regions and between them and other regions without the updates as a further check that the changes wouldn’t result in any failures / breakage. “I’m most worried about some data subtly changing or getting lost between crossings, Simon added in this regard, following the test. “but I haven’t seen anything like that.”

Details on the updates related to legacy avatar baking will be posted with the package release notes, when available.

SL Viewer

On Monday, January 5th, the HTTP pipelining RC viewer was updated to version 3.7.24.297623, bringing it up to par with the current release viewer, and therefore matching the Experience Keys RC viewer which slipped out just before Christmas.

Experience Keys / Tools

“It’s really quite close,” Oz Linden said of the Experience Keys / Tools project at the SBUG meeting. “We’re upgrading and testing some back end infrastructure to support it; when that’s ready, we’re good to go.”

As indicated in my original overview of Experience Keys / Tools, the tools come with a number of safeguards to reduce the risk of them being used for mischief. In addition, and as a further discouragement, those wishing to use the tools to build experiences will be required to pay a fee. This has now been set by the Lab, but is not at this time being made public. Expect to hear more about it when the tools are formally released.

In the meantime, you can read more on the project in these pages using the Experience Keys tag, and those wishing to try-out beta Experiences can do so via the Seamless Experiences section of the Destination Guide. You do not need to have the Experience Keys project viewer in order to do so – although it does provide you with access to more information about any Experience you try – see my project viewer overview for details (do keep in mind that both this and the project overview linked-to above are now several months old, and certain details may have changed in the interim; I’ll have a further article on Experiences when they are launched).

Group Chat

Simon Linden is continuing to work on group chat. No major news at this time, other than he’s been carrying out further digging into why some servers seem to get “stuck” every two weeks or so and require a restart. Further data was gathered during the region crossing tests mentioned above.

Other Items

Alpha Map Support for Mesh

I first reported on this matter, which forms feature request BUG-8100 – in week 52. Since then, the idea has received a lot more feedback and further thought. However, following initial triage, the JIRA was closed by Kyle Linden on Wednesday, January 7th, with the standard, “We’ve reviewed your request and determined that it is not something we can tackle at this time.”

SL project updates: week 52: viewer, misc items

Sarawak; Inara Pey, August 2014, on FlickrSarawak (Flickr) – blog post

Server Deployments

With the no change window in effect throughout the week, and running through until the 2nd week of January 2015, there were no server deployments to ether the main channel or the three RC channels during the last full week of 2014.

SL Viewer

The Experience Tools RC viewer was updated on Monday, December 22nd to version 3.7.24.297643 (although the Alternate Viewers wiki page has yet to be updated). This saw the viewer brought up to parity with the current release viewer.

2015 Updates

Early January 2015 should see the Windows and Mac viewer start to use the new viewer tools chain the Lab has been working on, and the updated autobuild process.One of the hopes with the Windows switch-over to Visual Studio 2013,  and the availability of Visual Studio Community 2013, is hoped that over time, many (or all) of the differences between the open source build configurations and the Linden versions can be eliminated, other than when using  proprietary packages.

Oz Linden has been working on the Linux side of things in order to get the Linux builds working with the new tools and gcc 4.6; he’s also actively soliciting for assistance from TPV developers for help in this.

Once the tools work is completed, it would appear that “avatar awareness” (aka “radar”) for the official viewer may well be heading towards the top of the list for new viewer capabilities, with Oz indicating he’d like to get to work on a specification for the capability. If not this, then quite possibly a further round of environment updates within the viewer, as noted in my week 51 report.

Other Items

SL Wiki Update

It is still not clear when the SL wiki will be re-opened for editing by SL users. According to Oz Linden, speaking at the Open-source Developer’s meeting on Monday, December 22nd, “every time they get close to finishing the QA, another batch of security problems comes out that we need to integrate fixes for.”

Alpha Map Support for Mesh

JIRA BUG-8100 has been raised as a feature request to provide an additional material map option alongside the existing diffuse, specular, and normal maps that allows a user to apply either a black and white map, or an alpha bit texture to mask out areas of a mesh and render them fully transparent (with a 1-bit edging). The JIRA has gained support and feedback from content creators (including the need for LSL from the outset, if implemented. Those interested / in agreement, should ensure they read the JIRA and WATCH it (remember, VOTE is not as strongly responded to by the Lab).

Next Meetings

  • Open-source Developers: Monday, January 5th.
  • Simulator User Group: Tuesday, January 6th.
  • Server Beta User Group: Thursday, January 8th.
  • TPV Developer: Friday, January 16th.

With thanks to Mona Eberhardt for the Open-source dev meeting notes and the BUG-8100 pointer.

The following notes are taken from the Server Beta User Group (SBUG) meeting held on Thursday, December 18th, 2014, and the TPV Developer meeting held on Friday, December 19th. A video of the latter is included at the end of the article, my thanks as always to North for recording it and providing it for embedding.

With reference to the meeting video, summary notes are provided below with time stamps to assist is spotting and listening to the associated conversations.

Server Deployments Week 51 – Recap

  • On Tuesday, December 16th, the Main (SLS) channel was updated with the server maintenance package deployed to the three RC channels in week #50
  • There were no deployments to the RC channels.

The end-of-year code freeze / no change window comes into effect from the end of the week, this means there will be no further server updates until January 2015.

SL Viewer

Release Viewer

The Maintenance RC viewer, version 3.7.23.297296, was promoted to the de facto release viewer on Thursday, December 18th. This viewer comprises a solid collection of bug fixes and improvements to many areas of SL, and also includes a range of fixes to previously released changes in the way joint offsets in rigged meshes are handled. Please refer to the release notes for further information.

Experience Keys RC Viewer

On Wednesday, December 17th, the Experience Keys / Tools viewer was updated to release candidate status with the release for version 3.7.23.297364. Please refer to my overview of the viewer (written while it was at project viewer status) for information on the viewer.

Further RC Updates

[00:50] As a result of the promotion of the Maintenance RC, both the new Experience Keys RC viewer and the HTTP Pipelining RC viewer are currently being rebuilt to include the Maintenance release code. These updates may appear in the release viewer pipeline on Monday, December 22nd, or they may be held over from release until after the end of the no change window.

Viewer Build Tools Project

[01:41] The new year should also see the first release of a project viewer for Mac and Windows built using the new build tools chain and autobuild process.

Group Chat

The last of the 2014 updates are being deployed to the back-end servers. At the time of the Server Beta User Group meeting, there were just a “few more” hosts that had yet to receive the updates, so things should be completed in short order. These improvement are focused on improving the overall robustness of the service and dealing with overload conditions.

CDN Work

What is being referred to as a “mini CDN” test was carried out on the BlueSteel region on the morning (PDT) of Thursday, December 18th. The test was designed to check a more flexible  CDN configuration that is going to make it easier for  the Lab to deal with fall overs. “It should be invisible normally but lets us have better control of where the viewer gets those mesh and texture assets,” Simon Linden said of the work, which will likely see a formal deployment in the New Year.

Viewer-managed Marketplace (VMM)

[03:53] There was an in-world meeting held on Friday, December 12th to discuss the Viewer-managed Marketplace (notes and transcript).

There should be a summary post from the Lab, covering JIRAs raised on VMM and comments made on the forums, which should be appearing on the current forum thread around the time this update is published. A further feedback meeting is being planned for the New Year.
