2018 SL UG updates #29/1: Simulator User Group

Abandale; Inara Pey, July 2018, on FlickrAbandaleblog post

Sever Deployments

Please refer to the server deployment thread for the latest updates.

  • There was no SLS main channel deployment or restart on Tuesday, July 17th, 2018, leaving regions on that channel running on server release 18#18.06.14.516450.
  • On Wednesday, July 18th, the release candidate channels should be as follows:
    • Bluesteel and LeTigre will remain on server release 18#18.07.03.517389 and will not be restarted.
    • Magnum should receive a new server maintenance package, 18#18.07.11.517746, comprising “internal fixes”.

The Main channel roll – which was to have included Animesh – was postponed, as Simon Linden explained at the Simulator User Group on Tuesday, July 17th:

We unfortunately held back this morning’s update with the Animesh roll. Late last week we found some code that is probably causing problems with the physics shapes of mesh bodies … not Animesh, but other normal mesh stuff …  Not using the correct physics shape. When building with mesh, there are a few ways to set that shape, and the Animesh code changes affected that code.

Simon Linden, SUG meeting, Tuesday, July 17th 2018.

It should be pointed out that in the context of Simon’s comments, “mesh bodies” means “in-world mesh objects, as worn mesh items doesn’t have a physics shape per se.

Deployment of the Animesh code to the SLS channel will therefore likely await the deployment of a fix for the issues encountered.

SL Viewer

There have been no Sl viewer updates / changes to mark the start of the week, leaving the pipelines as follows:

  • Current Release version 5.1.6.516459 and dated June 15, promoted June 21 – formerly the Pálinka Maintenance Release Candidate – No Change
  • Release channel cohorts:
    • Quinquina Maintenance RC viewer updated to version 5.1.7.517594, on July 12.
  • Project viewers:
  • Linux Spur viewer, version 5.0.9.329906, dated November 17, 2017 and promoted to release status 29 November – offered pending a Linux version of the Alex Ivy viewer code.
  • Obsolete platform viewer, version 3.7.28.300847, May 8, 2015 – provided for users on Windows XP and OS X versions below 10.7.

Attachment Loss / Ghosting on Teleport / Region Crossing

Some people are reporting loss / ghosting of attachments on teleporting. The problems sees to vary in the number of teleports taken before it is noticed, and tends to take the form of others noticing an avatar is missing parts, rather than the wearer (for whom everything still appears to be worn).

It’s not clear how widespread the issue is, although it seems it has been reported a lot through the Firestorm support groups. Mazidox Linden did confirm some attachment / region crossing testing was occurring on Aditi, but it’s not clear if this is in reference to this specific problem, or to with examining / improving region crossings in general.

Firestorm has a Refresh Attachments option (Advanced menu), however, addressing the issue from the viewer is seen as a less than optimal approach, a server-side fix being preferable.

Commenting on region crossings and attachments in general, Simon Linden said, “From what I can tell with my investigations so far, most attachment problems with region crossings come down to messaging failures, and then the viewer and region(s) get out of sync and don’t recover. ” He also noted that his own testing of “double” region crossings (e.g. cutting across the corner of a region while moving between two others) lead him to want to say “stop!” at the first, and not even attempt the second until the first hand-off have completed.

At this point I want to improve the code and communications so after a crossing, both regions and the viewer can agree that everyone is on the 2nd region with all attachments and vehicles and, when something goes wrong, try to recover … At both ends, viewer and region, it should be able to realize it’s been a few seconds and things are missing or not, and then re-try.

Simon Linden on investigating region crossing, Tuesday, July 17th, 2018

As an aside, one of the reasons the Lab is working on region crossings and attachment issues beside trying to make region crossings smoother and more predictable in general, is so that they might increase the limit on the number of attachments that can be simultaneously worn (currently 38). However, as Oz Linden noted at the Simulator User Group meeting, this won’t happen until such time as attachments can remain reliably … attached.

2018 SL UG updates #28/2: TPVD meeting

ChouchouMemento Moriblog post

The majority of the following notes are taken from the TPV Developer meeting held on Friday, July 13th 2018. A video of the meeting is embedded below, my thanks as always to North for recording and providing it. This was a short meeting – just over 30 minutes in length, but with some significant pauses throughout.

SL Viewer

The Quinquina Maintenance RC viewer updated to version 5.1.7.517594, on July 12th. All other SL viewers in the various pipelines remain as for the start of the week:

  • Current Release version 5.1.6.516459 and dated June 15th, promoted June 21st – formerly the Pálinka Maintenance Release Candidate – No Change
  • Project viewers:
  • Linux Spur viewer, version 5.0.9.329906, dated November 17th, 2017 and promoted to release status 29th November – offered pending a Linux version of the Alex Ivy viewer code.
  • Obsolete platform viewer, version 3.7.28.300847, May 8th, 2015 – provided for users on Windows XP and OS X versions below 10.7. This viewer will remain available for as long as reasonable, but will not be updated with new features or bug fixes.

Animesh

[0:44-2:20] Some bugs have surfaced in the server-side Animesh code which may delay the code from being deployed to the Main (SLS) channel in week #29 (commencing Monday, July 16th).

There is still some validation testing going on for the LOD / bounding box issue in Animesh viewer, but the viewer should be promoted to release candidate status “fairly soon”, possibly by the time the server-side code has been deployed grid-wide.

Bakes On Mesh

[2:21-2:38] A further update to the Bakes on Mesh project viewer is anticipated, possibly in week #29 (commencing Monday, July 16th). This will include several bug fixes.

Upcoming Project Viewers

Environmental Enhancement Project (EEP)

[3:01-3:40] A project viewer for EEP should be surfacing soon, but the functionality will not be available on the Main grid until the supporting back-end inventory updates have been deployed to Agni.

Texture Caching Updates

[3:44-4:21] A project viewer (the TCO viewer) with new texture caching capabilities is still anticipated as coming soonTM.

Estate Management Tools Updates

[4:45-5:27 and 21:59-23:31] A viewer supporting the updates to the estate management tools – improved ban lists, etc., had been held up while some issues around Friend requests and group invites are fixed (these issues are related to the recently introduced capability to deliver off-line IMs, etc., via HTTP rather than UDP, with group invites and friendship offers requiring more back-end updates in order to work correctly through the new capability). These issues have now been resolved, and both the server-side updates and the viewer changes are with the Lab’s QA team.

Last Names

[16:30-20:25] Still no date for roll out, but as these keep coming up:

  • There are no plans to re-introduce legacy last names (i.e. no Pey, Widdershin, Sideways, Munro, Fizzle, etc.).
    • [27:27 (text) and 28:18-28:25] However, a suggestion was put forward in the meeting to offer legacy names at a higher price than other last names, and Oz indicated this might be considered.
  • People will be able to suggest last name options (excluding legacy last names, per above).
  • There will be no change to Display Names, which will remain available as an option for those wishing to continue using them.
  • Changing your name will levy a real-world fee – the exact amount is still TBD.

A focus on the work for this is updating back-end services so they properly support / recognised changed names. Until this work is completed, the Last Names capability cannot be deployed.

In Brief

  • [5:43-6:36] Dynamic user interface (DUI): referred to at the recent Meet the Lindens sessions at SL15B, the ability to separate floater and panels out from the main viewer window is not being worked on at present, and so it is extremely unlikely anything on this will appear in 2018.
    • For a broader discussion on the idea and some of the Lab’s thinking on is – please refer to this section of my SL15B summaries.
  • [7:11-7:30] Multi-core graphic pipeline: raised at the meeting, this is not something the Lab is liable to tackle at the moment. A more important focus is how to handle Apple’s deprecation of OpenGL.
  • [9:29-9:45, with text comments to 11:43] BUG-225039: “with transparent texture and alpha masking at cut-off 1, the underlying colour shows through in small patches” – the Lab is actively investigating this.

 

2018 SL UG updates #28/1: simulator user group / EEP

Aphantasia; Inara Pey, June 2018, on FlickrAphantasiablog post

Sever Deployments

Please refer to the server deployment thread for the latest updates.

  • There was no SLS main channel deployment on Tuesday, July 10th, 2018, leaving regions on that channel running on server release 18#18.06.14.516450. However, due to the “14 day rule”, region on the main channel were restarted.
  • On Wednesday, July 11th, the release candidate channels should receive server update package 18#18.07.03.517389, comprising “additional internal tweaks”.

Both of the RC updates will include changes to the Animesh code currently deployed to the RC to allow better logging of Animesh related activities.

SL Viewer

At the time of writing, there had been no SL viewer updates to mark the start of the week, leaving things as follows:

  • Current Release version 5.1.6.516459 and dated June 15, promoted June 21 – formerly the Pálinka Maintenance Release Candidate – No Change
  • Release channel cohorts:
    • Quinquina Maintenance RC viewer, version 5.1.7.516813, released on June 22.
  • Project viewers:
  • Linux Spur viewer, version 5.0.9.329906, dated November 17, 2017 and promoted to release status 29 November – offered pending a Linux version of the Alex Ivy viewer code.
  • Obsolete platform viewer, version 3.7.28.300847, May 8, 2015 – provided for users on Windows XP and OS X versions below 10.7.

Environment Enhancement Project (EEP)

This is the project to introduce a set of environmental enhancements. Rider Linden is now engaged in internal testing a viewer supporting the new EEP capabilities, together with the server-side support. During the July 10th, 2018 SUG meeting, he provided a brief summary as to how the basics of EEP will work:

You can create what are called settings objects in your inventory. These settings objects [they are not prim-like not can they be rezzed in-world] represent either a water, a sky or a complete day cycle. We are providing interfaces that will let you set the parameters for each of these types of settings. (Very similar to the existing WL editors).

[Then,] from the context menu for a setting object you can apply it either to yourself, the parcel you are in or the region you are in. (The last two if you have rights to do so; you may also open the editor and a button there will let you apply to region or parcel as well).

Scripted support for EEP will be provided for agents (avatars) in experiences, but as I’ve noted in previous EEP updates in these pages, this scripted support will not be part of the initial EEP release, but will be added later.

Will there is now the ability to present different windlights at pre-set altitudes (to to 1,000m, then 1,000m up to 2,000m and then 2,000m up to 3,000m and 3,000m+), this may be seen as a less flexible approach that can be achieved through some third-party viewers, which allow much closer altitude zoning of windlight settings (e.g. have a windlight from, say 22m to 500m, another from 500m to 1,000m, etc.). .

The bar at Holly Kai park exemplifies a potential limitation of EEP. The bar is built-in to the base of a rock plateau, and currently, it is possible to define a viewer-side windlight that applies purely to the bar’s interior (i.e. up to a height of 32 metres above the sea floor). Above that limit (“above ground” so to speak), the parcel uses the same daylight windlight as the rest of the region. EEP’s 1,000 metre altitude zoning effectively prevents this.

How big an issue this might be remains to be seen – but it is not unfair to say there is a reasonable number of regions scattered across the grid where EEPs altitude zoning could force a repositioning of different sky builds using local windlights, should it become the only means of applying localised windlight – which might not be initially popular.

In Brief

Retrieving Grid Statistics Page via llHTTPRequest (see BUG-216320): trying to retrieve grid statistics via a script results in a 499 error, although queries via web browsers will still succeed. No remedial work has been done on this.

JIRA Bug report fields issue (BUG-1074): the fields used in the Create form for a bug report do not use the same titles as the fields seen in a filed bug report, nor are they in the same order. This makes submitting a bug report confusing for anyone not used to the SL JIRA (they can’t even look at a filed report to easily see what they sound be entering in the fields of the submission form). This is something the Lab might fix following the deployment of an upcoming JIRA update.
