Server Deployments

There was no scheduled Main (SLS) deployment on Tuesday, February 23rd. On Wednesday, February 24th, all three RC channel should all receive the same new server maintenance package, comprising a server crash fix and “minor internal improvements.”

It is likely the server deployments will remain at a slower pace over the next few weeks as the Lab focuses on internal infrastructure changes.

SL Viewer

On Monday, February 22nd the HTTP / Vivox RC viewer updated to version 4.0.2.311302. The see the additions of the following fixes:

  • MAINT-5295 Extra setopt in PUT case for llcore::http forces PUT to POST
  • MAINT-5625 [Project Azumarill] Selected Objects Show Land Impact of 0
  • MAINT-5628 [Project Azumarill] When posting to Flickr, Upload button does not grey out when upload is in progress, clicking Upload more than once results in all images failing to post
  • MAINT-5629 Viewer Makes Request for SRV Records on Login
  • MAINT-5676 Azumarill repeatedly requests weight of selected objects in edit mode
  • MAINT-5978 Convert the Vivox state machine over to a coroutine implementation
  • MAINT-6071 Reference to a UUID used after iterator is lost.
  • MAINT-6086 Crash when removing non added Vivox session.

The remaining RC and project viewers remain unchanged from week #7:

  • Quick Graphics RC viewer, version 4.0.2.311103 dated February 17th Avatar Complexity options and the new graphics preset capabilities
  • Maintenance RC viewer,  4.0.2.310545 dated February 2nd – 38 updates. fixes and tweaks
  • Project Bento (avatar skeleton extensions), version 5.0.0.310099 dated 20th
  • Oculus Rift project viewer, version 3.7.18.295296 dated October 13th, 2015
  • 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.

This all leaves the release viewer unchanged: version 4.0.1.310054, dated January 15th.

SL project updates 16 7/2: Unscheduled server deployments; SL viewer

Unscheduled Server Deployments

Update, February 19th, 22:40 GMT: the SLS channel restarts have been completed and the Lab has issued a blog post on why they were required, which I’ve also blogged about. 

Update, February 19th: the deployment of the update referred to below will commence at 15:00 SLT. 

On Thursday, February 18th, there was an unscheduled server deployment to all three RC channels, which at the time of deployment was described as an, “Update on the simhosts. Nothing is changing Second Life functionality wise.”

Speaking at the Server Beta User Group meeting following the deployment, Steven Linden had this to say:

We had an unscheduled RC deploy earlier today. It’s for a security vulnerability that was released, and we discovered that Second Life regions were vulnerable. A full public post-mortem will be coming after we deploy to the rest of the main grid. I can’t say until it goes out to the rest of Agni; I can say that it was related to region availability only…. I honestly can’t say a great deal, other than we have a fix, and that it’s coming very soon to the rest of Agni.

All Steven could say about the issue was that a) it was related to region availability; b) it could only be exploited from within Second Life; c) there has been no evidence the issue  is being actively exploited on Agni.

However, given the apparent urgency of the situation, it is likely that the update deployed to the RC channels will be also be rolled to the Main (SLS) channel well ahead of Tuesday, the normal day for Main channel deployments and restarts.

I’ll have more on this following the post-mortem release from the Lab.

Scheduled Updates

Details are scant at the moment, but Wednesday, February 24th should see a new server maintenance package which includes some code clean up around the area of parcel bans. There’s no new functionality being added, and the changes shouldn’t break anything. More details when the update notes are published.

SL Viewer

The Quick Graphics RC viewer updated on Wednesday, February 17th to version 4.0.2.311103. This sees the addition of the following resolved issues:

  • MAINT-1945: Outgoing packets logging always says 0 bytes
  • MAINT-5613:  Complexity readings vary greatly for each avatar using the QuickGraphics viewer
  • MAINT-5620: Clicking on Graphics Preset title triggers favourite
  • MAINT-5681: Particles still render when complexity threshold is reached
  • MAINT-5682: Some avatars are invisible
  • MAINT-5685: Light still renders when complexity threshold is reached
  • MAINT-5690: Viewer crash when zooming out
  • MAINT-6070: Add detailed logging for how Avatar Rendering Complexity is computed.

The updates also sees the removal of SL-217: Document Avatar Complexity, from the list of resolved issues, presumably because the documentation is still a work-in-progress.

Other Items

Aditi Intellectual Property Tutorial

As mesh content creators are aware, in order to be able to upload mesh content to Second Life, you must a) have payment information on file, and b) complete the Intellectual Property Tutorial.  The same is also true for Aditi; however, a problem with the Aditi services has meant that some people have been unable to complete the tutorial there (accessed when you log-in to your Aditi dashboard), due to the test page failing to load / failing to display all the questions.

If you wish to use Aditi to upload test models of your mesh content, but have encountered issues in trying to complete the tutorial, the interim workaround is to try refreshing the page to force it to load, as there appears to be a load balancing issue in the Aditi back-end services. However, the issue is expected to be resolved for next week.

Server Deployments

There are no server deployments planned for this week, and no planned restarts for any of the channels.

There is an RC deployment planned for week #8 (week commencing Monday, February 22nd), details of which are still TBA.

As there have not been any rolling restarts, and won’t be any across the entire grid until around week #9, the advice is that if your region is behaving abnormally, file a support ticket to have it restarted. The Lab’s support team are aware that there are no scheduled restarts at present, so they should process requests OK.

SL Viewer

With Monday having been a holiday in the United States (Presidents’ Day), there was no meeting at the Lab to discuss viewer promotions.  This leaves the current list of Lab viewer unchanged from the end of week #6:

  • Current Release version: 4.0.1.310054, January 15 – formerly the Maintenance RC viewer download page, release notes
  • RC viewers:
    • HTTP updates and Vivox RC viewer updated to version 4.0.2.310660 on February 4 – combines the Project Azumarill RC and Vivox Voice RC updates into a single viewer  (download and release notes)
    • Maintenance RC viewer version 4.0.2.310545 released on February 2 – 38 updates. fixes and tweaks for memory leaks; viewer crashes; UI, permissions and mesh uploader bugs; visual muting issues, autopilot issues and duplicated calling cards (download and release notes)
    • Quick Graphics RC viewer updated to version 4.0.2.310127 on January 20 – provides the new Avatar Complexity options and the new graphics preset capabilities for setting, saving and restoring graphic settings for use in difference environments / circumstances (download and release notes)
  • Project viewers:
    • Project Bento (avatar skeleton extensions) version 5.0.0.310099 released on January 20 – adds 90+ bones to the existing avatar skeleton (download and release notes)
    • Oculus Rift project viewer updated to version 3.7.18.295296 on October 13, 2015 – Oculus Rift DK2 support (download and release notes)
  • 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 (download and release notes).

As noted in my recent TPVD meeting report, further updates are expected to the HTTP / Vivox RC viewer and the Quick Graphics RC viewer, but these may not appear this week.

Region Crossings – Grey Box Issue

There have been increasing reports of region crossing issues, including the return of the “grey box” attachment issue which was originally seen in 2013 when crossing from a BlueSteel RC to any other region. This would see any passenger(s) sitting on a vehicle surrounded by (or even replaced by) a grey prim, and left with no choice but to relog, leaving the prim behind, attached to the vehicle.

Caitlyn recently got caught by the "grey box" issue as we were sailing on the north side of Blake Sea. If you encounter the problem, please file a JIRA with as much information as possible (see below)
Caitlyn recently got caught by the “grey box” issue as we were sailing on the north side of Blake Sea. If you encounter the problem, please file a JIRA with as much information as possible (see below)

At the time of the problem first appearing, Kelly Linden described it thus:

Every agent has a ‘task’ representation on the server that is the same as a prim. The bug is in sending the linked set w/ avatars to the other region: avatars after the first are losing the special avatar treatment and getting passed as a regular linked prim. So that prim is what the server thinks all avatars look like.

Simon then added:

The region crossing code basically un-sits avatars from an object, sends both the avatars and object to the next region [as separate sets of data], which puts them back together. In this case, the 2nd avatar doesn’t get detached properly and things go south from there. So the 2nd avatar gets sent over bundled up with the object … which it’s not designed to do.

It had been thought this issue had been dealt with via a fix for (non-public) BUG-3547. However, if it is resurfacing, the problem now is to pin it down in a reproducible manner, if indeed it is returning. Should you encounter it, please make sure you file a JIRA providing as much information as possible, including your viewer log files, the regions you were crossing between when it happened yo you (or your passengers), the date and time, details of the vehicle you were using, etc.

Server Deployments

There are no server deployments planned for week #6. The reason for this is that most of the staff directly involved in developing and enhancing the platform – the engineering team, product teams, etc., are meeting to discuss plans for further enhancements and improvement to Second Life in the coming month, as existing projects such as Bento continue to unfold.

This more than likely means the next deployment will take place Wednesday, February 17th, 2016, to at least one of the RC channels.

This also means the detailed project information is liable to be a little light this week as well.

SL Viewer

The HTTP / Vivox RC viewer was updated post my last SL projects Updates in week #5. Version 4.0.2.310660, issued on February 4th. This update includes three new fixes:

  • MAINT-6055 [corehttp] Win or Mac – voice does not stay connected on resume from sleep
  • MAINT-6064 Voice disappeared after rejected IM call
  • MAINT-6108 Cannot turn off ‘Console Window on next Run’ option in develop menu.

There has been no promotion to release viewer for any of the current RCs, which leaves things as follows for the release channel and project viewers:

  • Current Release version: 4.0.1.310054, January 15 – formerly the Maintenance RC viewer download page, release notes
  • RC viewer (+ the HTTP / Vivox RC above):
    • Maintenance RC viewer version 4.0.2.310545 released on February 2 – 38 updates. fixes and tweaks (download and release notes)
    • Quick Graphics RC viewer updated to version 4.0.2.310127 on January 20 – Avatar Complexity and graphics pre-sets (download and release notes)
  • Project viewers:
    • Project Bento (avatar skeleton extensions) version 5.0.0.310099 released on January 20 – adds 90+ bones to the existing avatar skeleton (download and release notes)
    • Oculus Rift project viewer updated to version 3.7.18.295296 on October 13, 2015 – Oculus Rift DK2 support (download and release notes)
  • Obsolete platform viewer version 3.7.28.300847 dated May 8, 2015 – Windows XP and OS X older than 10.7 (download and release notes)

Server Deployments

As always, check the server deployment thread for the latest updates.

On Tuesday, February 2nd, the Main (SLS) channel received server maintenance package 16.01.21.310177, previously deployed to the three RC channels, comprising Internal simulator fixes and a fix for BUG-1313 “LSL llSetPos in root prim of attachment behaves differently at high altitudes – viewer does not show updates”, which can cause attachments to fail to update correctly at altitudes over approximately 1500 metres.

There are no scheduled deployments to the RC channels for this week, and there are currently no plans for any deployments in week #6 (week commencing Monday, February 8th). Some suspect this is because nest week will see one of the semi-regular meetings those at the Lab directly involved in Second Life have to determine projects and priorities taking place.

Simulator Moves

The Tuesday rolling restart apparently included a number of simulators previously on the RC channels also being redeployed onto the Main (SLS) channel. There has been no word on why this is the case, although it might simply be a re-balancing of simulators between the various channels (Main, Magnum, LeTigre and BlueSteel), or part of a server load balancing operation (the Lab used to undertake periodic re-distribution of simulators by server, but I believe that process is far more automated nowadays).

SL Viewer

The anticipated Maintenance RC viewer arrived in the viewer release channel on Tuesday, February 2nd. Version 4.0.2.310545 includes some 38 updates and fixes for, but not limited to: memory leaks; viewer crashes; UI, permissions and mesh uploader bugs; visual muting issues, autopilot issues and duplicated calling cards (which should hopefully prevent people seeing some / many of the calling cards in their inventory duplicated each time they log-in to Second Life).

Outside of this, the current official viewers remain as:

  • Current Release version: 4.0.1.310054, January 15 – formerly the Maintenance RC viewer download page, release notes
  • Release channel cohorts (please see my notes on manually installing RC viewer versions if you wish to install any release candidate(s) yourself):
    • HTTP updates and Vivox RC viewer, version 4.0.2.310349, dated January 27th
    • Quick Graphics RC viewer, version 4.0.2.310127, dated January 20th
  • Project viewers:
    • Project Bento (avatar skeleton extensions), version 5.0.0.310099, dated January 20th
    • Oculus Rift project viewer, version 3.7.18.295296, dated October 13th, 2015
  • Obsolete platform viewer (Windows XP and OS X versions below 10.7), version 3.7.28.300847 dated May 8th, 2015.

Project Bento Bone Survey

Those involved in work with the Project Bento avatar skeleton extensions are reminded that the  Bento Bone Survey,  while currently open, but is liable to be closed soon. The survey intended to gauge the level of interest in various bone proposals for the Bento skeleton is now available. So if you are an animator or content creator with a vested interest in Project Bento, and if you haven’t already completed the survey, please make sure you do so sooner rather than later. The Lab will be using the results to help with prioritising which additional bones people would like to see added to the Second Life avatar skeleton as a part of the Bento work.

Server Deployments

As always, check the server deployment thread for the latest updates.

On Tuesday, January 26th, the Main (SLS) channel received the server maintenance package, 16.01.16.310114, previously deployed to the three RC channels. This comprises:

  • A simulator crash fix
  • A further feature request: llGetObjectDetails() functionality to get the parent_id of any task in the region (OBJECT_REZZER_KEY).

OBJECT_REZZER_KEY returns the parent_id of any task in the region. If the object came from an object rezzer it returns the ID of the parent object, while If it was rezzed by an avatar, it returns the agent ID of the avatar. The function only works for those objects rezzed in-world after the code deployment (objects in-world prior to deployment will return NULL_KEY).

On Wednesday, January 27th, the three RC channels should all receive a new server maintenance package,16.01.21.310177, comprising:

  • Internal simulator fixes
  • A fix for BUG-1313 “LSL llSetPos in root prim of attachment behaves differently at high altitudes – viewer does not show updates”, which can cause attachments to fail to update correctly at altitudes over approximately 1500 metres.

Deployment Slowdown

“FWIW, we’re likely to slow down on server updates in the next couple of weeks,” Simon Linden informed those attending the Simulator User Group meeting on Tuesday, January 26th. “It’s not part of any evil plan, but I’m doing some internal maintenance work and travelling one week.”

How this plays out remains to be seen, but we should at least have one deployment to the Main (SLS) channel in week #5 (week commencing Monday, February 1st), assuming no issues are found, with the promotion of the this week’s RC deployment to that channel.

SL Viewer

no updates for the start of the week, with the current crop of viewers remaining:

  • Current Release version: 4.0.1.310054, January 15 – formerly the Maintenance RC viewer download page, release notes
  • Release channel cohorts (please see my notes on manually installing RC viewer versions if you wish to install any release candidate(s) yourself):
    • HTTP updates and Vivox RC viewer, version 4.0.2.310097, dated January 19th
    • Quick Graphics RC viewer, version 4.0.2.310127, dated January 20th
  • Project viewers:
    • Project Bento (avatar skeleton extensions), version 5.0.0.310099, dated January 20th
    • Oculus Rift project viewer, version 3.7.18.295296, dated October 13th, 2015
  • Obsolete platform viewer (Windows XP and OSX versions below 10.7), version 3.7.28.300847 dated May 8th, 2015.

Greater Local Region Control

A bug which has been getting repeated requests for attention, particularly by those engaged in SL combat activities, is BUG-8974, “Temp rez object are not rezzed in a timely manner”. It’s also one which hasn’t seem to be working its way to the top of the pile of things to be done. During the Simulator User Group Meeting, Simon expanded on one of these reasons this is the case:

“As I remember, it’s tied up with a larger idea: letting region owners pick different settings for the region based on the performance and safety you want.  Part of the problem is due to a throttle which was added for anti-griefing. So if you want temp rezzing faster, you might want that [throttle] looser, while a venue owner would definitely not want that [the throttle looser, due to the risk of griefing]. I can’t make promises but I hope to get to it soon.  It’s still on my list.”
