Sever Deployments for Week 12

Second Life Server (SLS)

On Tuesday March 19th, the Main channel received the server maintenance package which had been re-deployed to Magnum in week 11. As with the Magnum re-deploy, it excludes the fix for VWR-786 while LL go “back to the drawing board” to try to correct issues. However, it does include the following two fixes:

BUG-1612: region Owners and estate managers finding they are unable to teleport back to their region after disabling direct teleports to the region
SVC-8019: region visibility delays following region restarts.

The release notes for the deployment are available on the SL wiki, as usual.

Release Candidate Channels

On Wednesday March 20th, the Release Candidate channels should receive the following updates:

BlueSteel and LeTigre: should receive the same updates as deployed to the SLS channel on Tuesday March 19th, but otherwise retain the same updates received in week 11 – release notes (BlueSteel)
Magnum: should receive further updates to Andrew Linden’s interest list work, as per the release notes. Specific interest list bug fixes included with this update comprise:
- Updates for objects that are out of view are delayed for a maximum of 5 seconds, at which point they will be sent (mitigates BUG-1779)
- Fix for “No object updates from vehicles after some region crossings” (BUG-1814)
- Fix for “Agent appears in incorrect position to other agents after being moved by a sim teleporter” (BUG-1795).

Server-side Baking

As reported in week 11, the second official Server-side Baking pile-on / load test appeared to go well on Thursday March 14th. Speaking at the Content Creator’s User Group meeting, SSB project lead Nyx Linden reported:

Looks like things are going well overall – the back-end services are performing well. There are still some inventory and attachment rezzing issues, but these are believed to not be regressions from current limits.

A few reports of issues, some of which we have fixes for, others we’re investigating, and we’re looking at what it would take to fix up the systems that were falling over … there were a couple of new bug reports we’re investigating.

A further SSB pile-on / load test conducted in Friday 15th March, but exclusively with the Firestorm viewer pre-release with SSB support. Numbers at the Firestorm test were roughly the same as those for the “official” test, and overall, the outcome was the same – much lower reported SSB issues, but similar problems with outfit attachments rezzing from inventory (or rather, failing to), which was common to both parts of the test.

The Firestorm SSB pile-on / load test, March 15th — Peoiple gather for the Firestorm SSB pile-on / load test, March 15th

The inventory issues have themselves become more of a focus of investigation outside of SSB itself (attachments aren’t affected by the SSB code changes, which relate directly to the likes of skin, shape and clothing layer changes. While the inventory issues were thought to relate solely to Aditi, Nyx indicated that the problem is likely common to Agni as well. commenting:

We were seeing similar failures in inventory, etc on both the old pipeline and the new pipeline, and in areas that we didn’t change. So if we repeated the test on Agni we think we’d see similar failures. We’re looking at the root causes, but attachment rezzing failures won’t necessarily block our first release … We’re looking at the inventory & attachment issues and where their root causes are.

Expect further updates on the latter issue as they become known.

HTTP Testing

All of the test regions for Monty Linden’s upcoming HTTP updates are now up-and-running on Aditi, and available for public access (allowing for the caps on avatars in the primary test regions). The regions are:

DRTSIM-203 (Agni default settings): TextureTest2, MeshTest2, and Sandbox HTTP
DRTSIM-203H (the “Happy” channel): TextureTest2H, MeshTest2H, Sandbox HTTP H
DRTSIM-203A (the “Angry”) channel): TextureTest2A, MeshTest2A, Sandbox HTTP A.

As noted in previous project reports, Monty is keep to have TPVs and scripters test the capabilities in order to gather more comprehensive data on his work.

SL project updates: week 11 (2): Server, SSB testing and HTTP news

Posted on March 15, 2013August 22, 2013 by Inara Pey

Update Match 18th: The “mesh only” HTTP test regions, referred to as “coming soon” in the HTTP section of this report are now online on Aditi, and are called MeshTest2 (DRTSIM-203), MeshTest2A (DRTSIM-203A) and MeshTest2H (DRTSIM-203H), respectively. In addition, the sandbox areas (unrestricted access) are also now available as Sandbox HTTP (DRTSIM-203), Sandbox HTTP A (DRTSIM-203A) and Sandbox HTTP H (DRTSIM-203H).

Server Deployments

The planned deployments for the week went ahead as scheduled. Namely:

On Tuesday March 12th, the Second Life Server (SLS) Main channel received Baker Linden’s large (as in complex) object rezzing project, designed to improve region performance when rezzing large objects – release notes
On Wednesday March 13th, the BlueSteel and LeTigre Release Candidate (RC) channels received a server maintenance package, intended to fix a common crash mode – release notes
Also on Wednesday March 13th, the Magnum RC channel received an update to the server maintenance package deployed in week 10, with further improvements / fixes. These included the removal of the fix for VWR-786, which rather than correctly fixing the known issue (IMs to friends not respecting their privacy settings) resulted in all IMs to non friends returning the “User is not online” message, regardless as to whether the recipient was online or not. Release notes for the package are on the SL wiki. The Lab, according to Maestro Linden, is going to have to, “Go back to the drawing board,” to resolve this problem.

As I’ve mentioned in past reports, the aim of this “large object” rezzing project from Baker Linden is to improve how complex objects (those which have a lot of scripts and / or a large file size), with the focus of the work moving the parsing of object files onto a background thread in order to prevent the simulator being choked and performance spiking when such objects are rezzed. As such, the work applies to both in-world objects and attachments, with mesh potentially being a primary beneficiary of the changes. The thought is that the new code may also help frustrate griefers, as the simulator FPS should be better when multiple scripted objects are being rezzed.

SL Viewer

The SL beta and development viewer were both updated on March 14th. The beta viewer moved to release 3.5.0.271843, with updates primarily aimed at CHUI, as anticipated. The development viewer moved to release 3.5.1.271846, and remains broadly in sync with the beta version of the viewer.

Vivox Updates

Alongside the FMODex (sound system) updates which will be forthcoming after the formal release of CHUI as mentioned in part 1 of this report, Vivox (the SL Voice service) is also due to be updated to version 4.5. Like FMODex, this is unlikely to happen until after CHUI has reached a formal release., but once implemented, this should result in an improvement in Voice quality.

Mesh Deformer

There is still no news on this. Both the issues relating to avatar shapes and weighting are still awaiting internal resources at LL. As such, there is no timeline as to when any movement might be seen on this project.

Interest List – Issues and Further Updates

More interest list updates on Aditi and likely heading for a Release Candidate channel in week 12.

The following fixes, related to the interest list code, should be in an RC deployment in week 12 (week commencing Monday March 18th):

A fix issue where you ‘lose track’ of a vehicle after a region crossing
A fix for BUG-1795 (“Agent appears in incorrect position to other agents after being moved by a sim teleporter”), which should see an end to avatars still appearing in view after they have used a teleport system
A fix for the issue where object moving off-camera would suddenly ‘snap’ into place when you turned your camera so they were in your field-of-view. Whereas up until now, the new interest list code has not sent any updates for such objects, the fix to be deployed in week 12 will once again allow updates to be sent to the viewer, but at a much lower rate than before the interest list code was originally deployed.

The code with these updates is currently available for testing on two regions on Aditi: Solariam (rated: Adult) and Tischeriidae (rated: Moderate). This code also includes updates to improve object rendering (particularly with the viewer set to low bandwidths) and to object cacheing as well, as noted in the first part of this report, and those wishing to do so are encouraged to do so, although testing any improvements to vehicle regions crossings might be contingent upon being Adult verified.

Server-side Baking (SSB) Pile-on / Load Test

The second SSB pile-on load test took place on Aditi on Thursday March 14th, immediately following the Server Beta User Group meeting. The test was undertaken using the latest version of the Sunshine project viewer and appeared to be broadly satisfactory, involving both users and a fair few LL personnel – Nyx (x2, as he had his alt there), Simon, Maestro, Monty, Dan, Don, Log, and others. As with the original test, this took place on two regions – one running the current baking system, the other running the new service. Participants were asked to change outfits using the current service, so that the project team could get some baseline / comparison stats, before everyone moved over to the “new” service on the adjoining region.

Playing with Pixieviewer

Posted on March 14, 2013August 22, 2013 by Inara Pey

Thomas Buchauer has been working on developing a virtual world viewer-in-a-browser. The work is still very much in its alpha stages, but already shows sign of promise for those who are OpenSim-based.

Pixieviewer is available now as a special “first look” release, with access restricted to a special test grid called, appropriately enough, Pixiegrid. It is also in non-public testing with two OpenSim grids, and the aim appears to be to make it generally available as a browser-based means of access OpenSim environments at some point in the future. The viewer utilises HTML 5 (and so runs of Firefox, Chrome, etc.), and runs on any portable / mobile device capable of running WebGL.

PixieViewer: accessing OpenSim through a web browser — Pixieviewer: accessing OpenSim through a web browser

As an initial “first look” release, functionality is obviously limited – although already offering enough to get people playing with things and see the potential. Capabilities currently included in the viewer comprise chat, building both using primitive (“basic”) shapes and pre-set 3D models (mesh is supported although uploads are currently not enabled), and the ability to send content to a file suitable for 3D printing on your own (data exported as an STL file), or have the data sent to http://i.materialise.com, where you can preview and order 3D prints. Some basic object interaction is also possible as well – such as sitting on objects or clicking them to display pop-up with further information.

You’ll need to create a log-in account to the Pixiegrid in order to try-out the viewer, and you can do so directly through the viewer’s log-in page.

General Looks

The preview version loads fast – once you’ve registered an account, you can fire-up the viewer and are immediately delivered to the Pixiegrid preview area, where you can wander, try out various options (including the 3D printing), chat with others and explore what is already available.

Avatars come in default male and female forms and are non-customisable at present – although you might find your hair colour changes between log-ins; I’ve tended to find I’m either a blonde or a red-head when using the viewer. Movement – both avatar and camera – is fairly basic, but more than adequate for getting around and seeing things; those who have followed Lumiya’s development will be aware how rapidly things like this improved, so it’s reasonable to expect PixieViewer will add further refinements as time and the technology allows.

SL project updates week 11 (1): server deployments, viewer, and interest list updates

Posted on March 13, 2013August 22, 2013 by Inara Pey

Server Deployments

Second Life Server (Main channel)

On Tuesday March 12th, the Main channel received Baker Linden’s large object rezzing project which had been deployed to BlueSteel and LeTigre in week 10. This project is designed to improve simulator handling of “large” (as a file size / complexity, rather than physical object size) so that the simulator does not stall / choke when handling one or more such objects. makes sim performance smoother while objects are being rezzed. Further details on the project are in my week 10 update, and the server release notes are available in the SL wiki.

Release Candidate Channels

On Wednesday March 13th, the Release Candidate channels should be updated as follows:

BlueSteel and LeTigre: both of these channels should be receiving the same server maintenance package, intended to fix a common crash mode – release notes
Magnum should receive an update to the server maintenance package it received in week 10, with further improvements / fixes. These include the removal of the fix for VWR-786, which rather than correctly fixing the known issue (IMs to friends do not respect their privacy settings) resulted in all IMs to non friends returning the “User is not online” message, regardless as to whether the recipient was online or not. Release notes for the package are on the SL wiki

SL Viewer

There has been no major viewer movement since the last update in week 10.

CHUI, the Communication Hub User Interface

CHUI looks set to be merged-in to the Snowglobe code, with Oz Linden stating he was hoping to start on this on Monday 11th March. There are concerns as to how LL’s ongoing work with the viewer might impact TPVs going forward. As it is, CHUI is liable to remain in the SL beta viewer for a while (and there is expected to be one more CHUI release into beta, as perviously noted).

Materials Project

Work is continuing on clearing the current issues within the viewer code, with a further push of the non-public viewer expected this week, which may resolve some of the problems.

The Potential LL Roadmap for Viewer Releases

While things are always in a state of flux, the potential order of viewer releases from LL’s perspective is currently veering towards:

Materials is now unlikely to “be seen” until after the code has merged with the CHUI code – this follow-on from the SSB code currently undergoing a merge with CHUI and the move to merge CHUI with the Snowglobe code mentioned above
This does not mean that a materials project viewer will not appear prior to CHUI reaching the SL release viewer; rather it means that when a materials project viewer appears, it is likely to have CHUI incorporated into it
That said, materials will likely only arrive in the release version of the SL viewer after CHUI has been formally released and (most likely) SSB has been deployed
Other updates – FMODex is currently awaiting CHUI as well, but has no clear release date; the same is true of the Mac Cocoa project. Currently, it appears as if these are unlikely to reach mainstream release until after CHUI has been formally released.

Most TPVs are currently focusing on the Server-side Baking (SSB) integration, as this has a significantly greater impact on viewers in terms of the impact on users than CHUI (although the latter is by far the most complex update as it involves a lot of code refactoring as well as CHUI updates). As such, it is likely to be a while before CHUI starts appearing in the majority of third-party viewers (although Kokua has already merged with it, and now has the CHUI code in the beta branch of its code).

Merchant Outbox Project Viewer

As reported over the weekend, Linden Lab has re-issued the Merchant Outbox project viewer, updated to the 3.4.4 viewer code, but which does not incorporate CHUI. This release is purely to assist merchants who are encountering issues in migrating to Direct Delivery now that the initial retirement of Magic Boxes has been announced.

Those who have / are encountering problems in migrating to Direct Delivery can obtain the viewer from the Alternate Viewers wiki page.

This project viewer will be withdrawn at some point in the future, and will not impact other viewer releases.
