Server Deployments: week 6 – recap

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

  • On Tuesday February 4th, the Main channel received the server maintenance package previously on the three RC channels, which includes a crash mode fix and a fix for llModifyLand() modifying the wrong location in region, when called in a child prim. See part 1 of this report for further details
  • On Wednesday February 5th, all three RCs received a new server maintenance package, which includes a crash fix.

It seems there may not be any RC deployment in week 7. A number of things are being worked on, but there’s nothing ready for release as yet, but that could change between now and Wednesday next.

SL Viewer Updates

Fitted Mesh

As expected, the Fitted Mesh RC received a further update on Wednesday February 5th, with the release of version 3.7.0.286015. This update was to incorporate a further fix for issues relating to FITMESH-6 and FITMESH-20, after Latif Khalifa of the Singularity team spotted a coding error in the original fix.

SL log-in Servers Redeployment

Coyot Linden: SL log-in server updates
Coyot Linden: SL log-in server updates

On Thursday February 6th, Linden Lab redeployed the log-in servers. The aim of this work was to bring them up to a current operating system version (the one they have been running on being some two years old). There was no change in functionality, and as the work was seamless from a user perspective, there was no blog post on the matter.  Commenting on the work at the Server Beta meeting on Thursday February 6th, Coyot Linden said the work involved

Newer versions of standard apps like webserver, caching app, etc., and all of the better functionality and security fixes that go with that. But nothing has changed about the login code or process.

This work was actually the reason log-ins on Aditi were broken ahead of the Server Beta meeting on Thursday January 30th: Aditi only has the one log-in server (as opposed to the 15 available to Agni, the main grid), and that was being used to test the update. The plan is for a second log-in server to be added to Aditi in order to avoid situation where the loss of a server prevents anyone from access the beta grid.

Vivox Work

As many are aware, there have been a number of Vivox issues (as well as FmodEx issues) affecting voice in SL.

On Tuesday February 4th, maintenance was performed on the Vivox backend which were mostly for quality enhancements for people using a recent version of the voice SDK. The changes didn’t involve any changes to the simulators, but as the updates are for a “recent” version of the voice SDK, it is questionable whether the enhancements will affect those TPVs using “older” versions of the SDK (e.g. Firestorm 4.4.2 is using an older version of the SDK, although upcoming releases will be on a par with the LL viewer).

Server Deployments: week 6

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

Main (SLS) Channel

On Tuesday February 4th, the Main channel received the server maintenance package previously on the three RC channels, which includes a crash mode fix and a fix for llModifyLand() modifying the wrong location in region, when called in a child prim.

Speaking at the Server Beta meeting on Thursday January 23rd, Maestro Linden described this fix thus:

For example, if a child prim is offset by <8,4,0> from the root prim, then calling that function in the child prim will try to modify the terrain at <8,4,0>  of the region,  which may or may not work depending on who owns the parcel.

The fix is to make it modify the land underneath the child prim (which of course follows the same permissions rules – you can only modify land owned by the script owner.

Release Candidate Channels

On Wednesday February 5th, all three RCs should receive a new server maintenance package, which includes a crash fix.

SL Viewer Updates

Google Breakpad

Google Breakpad reappeared in the viewer release channel as an RC (version 3.6.14.285686, dated January 29th) on February 4th. As per usual, the RC does not contain any functional changes or updates, but contains a Google Breakpad updates and restructures the crash reporting mechanism to support out of process crash reporting. These changes will give the development team more call stacks from crashes more frequently, to improve the triaging and debugging of issues.

HTTP Viewer

The HTTP RC gained a further update on Monday, February 3rd, with the release of  version 3.6.14.286010, although it had been anticipated this viewer might update to the de facto release viewer this week.

AIS v3

The Server-side Appearance “polish” and AIS v3 project viewer, version 3.6.14.285190 was released on Tuesday February 4th. In terms of SSA This includes:

  • Stability and performance improvements for SSA: retry logic, removing redundant requests, detecting various appearance stuck conditions.
  • Code cleanup with the removal of a lot of code related to the old client-side baking framework.
  • Bug fixes, mostly appearance-related
  • Support for AIS v3 (which requires server-side updates.

For more information, see my announcement of the release.

Group Ban Lists

Baker Linden continues to work on Group Ban Lists, commenting at the Simulator User Group meeting on Tuesday February 4th that, “I’m finally finished with (what I think is) the major viewer side changes, so I’ll be getting everything ready this week for a deploy hopefully in the next upcoming weeks, so be ready to test the crap out of group bans on Aditi soon!”

SL projects updates 5/1: server releases & fitted mesh

Server Deployments Week 5

Main (SLS) Channel

On Tuesday January 28th, the Main channel received the server maintenance project previously on the three RC channels, which contains a single fix for a crash mode.

RC Channels

On Wednesday January 29th, all three RC channels should receive a new server maintenance project, which includes a crash mode fix and a fix for llModifyLand() modifying the wrong location in region, when called in a child prim.

Speaking at the Server Beta meeting on Thursday January 23rd, Maestro Linden described the llModifyLand() fix thus:

For example, if a child prim is offset by <8,4,0> from the root prim, then calling that function in the child prim will try to modify the terrain at <8,4,0>  of the region,  which may or may not work depending on who owns the parcel.

The fix is to make it modify the land underneath the child prim (which of course follows the same permissions rules – you can only modify land owned by the script owner.

SL Viewer Updates

The Fitted Mesh RC was updated on Monday January 27th with the release of version 3.7.0.285669.  This includes a number of additional fixes, include those for FITMESH-20 and FITMESH-6, which can be summarised as:

  • FITMESH-20: certain non-rigged mesh invisible with ALM disabled
  • FITMESH-6: worn mesh which is not rigged to the collision bones is seen to stretch away towards the 0,0,0 point of the region the avatar is standing in when using the Fitted Mesh

An interesting emerging issue with Fitted Mesh – which likely won’t delay its eventual promotion to release status – is that it prevents the Firestorm Bridge from attaching.

The Bridge is a is a scripted object which is used by the Firestorm viewer for a number of functions, notably: Move To Teleport, Flight Assist, Script Count, some radar functions, and Movelock. The problem here is that the Bridge uses a dedicated attachment point (127), which doesn’t seem to be supported or allowed in the Fitted Mesh viewer code. It is currently unclear as to how this might be resolved.

There has yet to be a promotion to the defacto release viewer. If there is to be such a promotion this week, it would seem likely that the Interest List RC would be the one to make it.

Other Items

Viewer Script Debug Window

During the Simulator UG meeting on Tuesday January 28th, Jonathan Yap asked, “Has any thought ever been given to a script debug window? t would let you input commands to trigger events etc.”

Kelly Linden, chairing the meeting in Simon Linden’s absence, replied:

Short answer is yes it has been thought about. A lot of what you expect from a debugger is very difficult in LSL and harder in LSL-on-Mono, such as most of looking at the actual state of the script. Being able to trigger events is an interesting idea but I think it has some security concerns if not handled very carefully.

So, to elongate  Kelly’s initial short answer, while it has been thought about, it’s not something that is likely to happen any time soon.

Server Deployments Week 4 Recap

As always, please refer to the deployment thread in the forums for the very latest news.

Server Deployments in Week 5

Details on the deployments for week 5 (commencing Monday January 27th) have yet to be finalised. However, it appears there will be a new server maintenance projects targeted at the RC channel, which Maestro Linden outlined during the Server Beta meeting on Thursday January 23rd:

We’ll have another small maintenance project going out next week which includes another crash fix and a fix to llModifyLand(), [where] the bug is that calling it in a child prim modifies the wrong land.

For example, if a child prim is offset by <8,4,0> from the root prim, then calling that function in the child prim will try to modify the terrain at <8,4,0>  of the region,  which may or may not work depending on who owns the parcel.

The fix is to make it modify the land underneath the child prim (which of course follows the same permissions rules – you can only modify land owned by the script owner.

Unless another project pops-up in the interim, it is likely this update will be deployed to all three RC channels in week 5.

SL Viewer Updates

A new Maintenance RC viewer appeared in the release channel on Thursday January 23rd. Version 3.6.14.285499 includes some 43 MAINT related fixes and updates, as listed in the release notes.

All other viewer RC, project and the release viewer remain unchanged, per my notes in part one of this week’s report.

HTTP Work – Monty Linden

Monty attended the Server Beta meeting to provide some more information on the HTTP project work.

“Basically, my hope is to move http operations to a domain where ping time has far less impact on experience as well as just doing HTTP better,” he said of the current work, the benefits of which are currently in an RC viewer – version 3.6.14.285253. “And that is happening.” (See Monty’s blog post on the subject.)

HTTP Pipelining

This work was slightly sidetracked as Monty got involved in issues around third-party libraries (see below). However, pipelining is seen as the first major step that will give the Lab some ping time independence, and it is likely that it will involve some server-side work.

“The server work will be small, a change in fairness policies,” Monty stated by way of a broad explanation, “and throttle implementation but that isn’t set in stone yet.”

Third-party Library Work

The work on the third-party libraries has been covered in a number of recent HTTP project updates. These are the used in building the SL viewer, including zlib, libpng, openssl, ares, libcurl, boost and SDL, all of which Monty has been rebuilding, as well as “tweaking” colladadom, openjpeg, Google-mock and llqtwebkit.

The aim is to ensure that these libraries are up-to-date, and are probably managed and maintained and correctly used throughout the viewer build process.  This work should help, longer-term with any move by the Lab to 64-bit viewer builds, and should be of benefit to those TPVs already building 64-bit variants of their viewers.

Webkit Woes

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.

There have been an increasing number of issues with Webkit. The libraries used within SL are out-of-date, for example, something which has caused the Lab and TPVs a considerable amount of pain.

More recently,  users have been encountering issues when trying to view YouTube videos via the built-in browser or MOAP, reporting that they are seeing an error message informing them that  “You’re using Safari browser on Windows that we’ll soon stop supporting” (BUG-4763 and FIRE-12642), or reporting they have sound but no video (FIRE-11057). An Adobe engineer has commented on the latter Firestorm JIRA, explaining the problem, and has indicated he has contacted Linden Lab as well.

It’s unclear as to how this matter will be handled going forward. While Monty has prodded at Webkit as a part of his additional work on third-party libraries, and overall fix may not be that straightforward. As such, it appears the way forward in dealing with the video issues is currently unclear.

SL projects updates 2014: week 4 (1): Server releases, viewer, snapshot uploads

Posted on by Inara Pey

Server Deployments, week 4

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

Main Channel: Tuesday January 21st, 2014

The Main channel received the server maintenance project which had been on the RC channels for the last couple of weeks. This comprises:

Details on the scaling functions can be found by following the links, or by checking my week 2 projects update. All of these functions, including llLoadURL can be used in any current viewer.

There were two further updates included in the package, both of which require viewer-side updates which have yet to be released by the Lab. These are:

  • Preliminary support for custom default permissions on newly created objects – currently awaiting viewer-side support via STORM-68
  • Preliminary support for the viewer fetching the LSL syntax rules from the simulator, for up-to-date syntax highlighting in the script editor – currently awaiting viewer-side support via STORM-1831.

Release Candidate Channels, Wednesday January 22nd, 2014

All three RC channels should receive the same server maintenance project, which contains a single fix for a crash mode.

SL Viewer

As per my last report, the “Project Interesting” viewer appears to be running at a substantially reduced crash rate, and has seen the majority of issues resolved within it. If this continues through the current week, given the amount of time the viewer has been in the release channel as an RC, it could be a good candidate for promotion to the de facto release viewer in week 5 (week commencing Monday January 27th), assuming the Lab keeps to its plans of promoting a release candidate  every two weeks.

the Fitted Mesh viewer is also a potential candidate for promotion. However, as there are currently two significant issues with this RC at present,  any promotion of this candidate may well be delayed.

The two issues concerned are:

  • Certain non-rigged mesh invisible with ALM disabled -see FITMESH-20 – which has been confirmed by Marissa Linden and
  • worn mesh which is not rigged to the collision bones is seen to stretch away towards the 0,0,0 point of the region the avatar is standing in when using the Fitted Mesh viewer on systems with AMD graphics and with ALM turned off – see FITMESH-6 –  which Oz Linden has confirmed the Lab is investigating.
The Fimesh-6 issue, which affects how mesh garments not rigged to the collision bones can appear in the Fittted Mesh viewer running on systems using AMD graphics and with ALM disabled, is getting a further look at from the Lab

Snapshot Uploads to SL Feeds

As many are aware, the ability to upload snapshots to the profile feeds was broken for many before the Christmas / New Year holidays. While the functionality was restored for some who could not upload snaps was restored, many have remained unable to use the facility. However, speaking at the  simulator User Group meeting on Tuesday January 21st, Simon Linden indicated that the Lab believe the issue has now been completely resolved for all users. I’ve not had time to test the upload myself due to RL issues, but those who have continued to experience problems my wish to try things out once more. If problems are still evident, please raise a JIRA.

SL projects updates week 3 (2): upcoming server releases, Fitted Mesh, HTTP, Oculus Rift & more

Server Deployments: week 4

Because Monday January 20th is a holiday in the USA, Maestro Linden has posted details of the deployments which will take place in week 4. Despite the US holiday, the deployments will still take place on Tuesday and Wednesday as usual.

As always, please refer to the week’s forum deployment thread for the latest news and updates.

Main Channel: Tuesday January 21st, 2014

The Main channel should received the server maintenance project which has been on the RC channels for the last couple of weeks. As notes in previously SL projects updates in this blog, this comprises:

  • The forced delay in llLoadURL has been reduced to 0.1 seconds
  • New LSL functions for uniformly scaling linksets (integer llScaleByFactor(float scaling_factor), float llGetMinScaleFactor(),float llGetMaxScaleFactor() )
  • Preliminary support for custom default permissions on newly created objects – currently awaiting viewer-side support via STORM-68, which has yet to be released
  • Preliminary support for the viewer fetching the LSL syntax rules from the simulator, for up-to-date syntax highlighting in the script editor – currently awaiting viewer-side support via STORM-1831, which has yet to be released.

Release Candidate Channels, Wednesday January 22nd, 2014

All three RC channels should receive the same server maintenance project, which contains a single fix for a crash mode.

SL Viewer Updates

The following section contains notes taken during the TPV Developer meeting held on Friday January 17th, a video of which is included below. My thanks, as ever, to North for the latter.

Fitted Mesh

As reported here, the Fitted Mesh viewer reached release candidate status on Thursday January 16th, with the release of version 3.7.0.285178, which also includes a number of bug fixes and STORM contributions from third-party developers.

Issues Affecting ATI/AMD Users

There are reports of additional issues arising within the Fitted Mesh viewer which are not apparent in other version of the SL viewer.  These issues appear to impact those using ATI/AMD graphics cards and have Advanced Lighting Model disabled.

In the first issue, non-rigged mesh is invisible when viewed on the Fitted Mesh viewer (see FITMESH-20), which was reported for the new release candidate version of the viewer. In the second (FITMESH-6), worn mesh which is not rigged to the collision bones is seen to stretch away towards the 0,0,0 point of the region the avatar is standing in (which is oddly similar to how viewers without the Fitted Mesh updates render garments rigged to the collision bones in an avatar).

Again, these problems only appear to impact those using ATI/AMD graphics cards and who are running with ALM disabled. Initially, the problem had been thought by the Lab to be a  driver issue, but testing reveals the problem to occur across a range of ATI/AMD drivers, including the most recent Catalyst updates.

New Sliders and Asset

Redpoly Inventor has also raised a feature request (see FITMESH-19) for what he calls a “Mesh Clothing Adjuster” which can be used to scale specific parts of the collision skeleton in order to achieve better fitting for the likes of knee boots, tank top straps or any clothing that doesn’t look good with alphas. He also includes code with the JIRA which people can add to their viewer in order to create slider to the shape menu which controls the clavicle volumes.
