SL projects update week 9/1: server releases, viewer updates

Posted on by Inara Pey

Server Deployments: week 9

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

Main (SLS) Channel

On Tuesday February 25th, the Main channel was updated with the server maintenance package previously on all three RCs, which comprises the following:

  • Fix for BUG-5034 “If an EM restarts a region and then teleports out immediately, the EM will disconnect just after teleport”
  • Fixed a rare case in which e-mails read by LSL scripts immediately after rez or region change would sometimes be missing the message body
  • Fixed some crash modes

Release Candidate Channels

On Wednesday February 26th, the Release Candidate channels should be updated as follows:

  • BlueSteel and LeTigre should receive an infrastructure update, with no functional changes
  • Magnum should also receive the infrastructure update, and in addition have the server-side AIS v3 code enabled (the code having already been rolled-out to the grid – see the AIS section of my week 7 report). This code requires viewer-side updates to work (currently available as a project viewer), and should Improve performance and reliability when changing outfits (see my AIS reports in this blog).

SL Viewer Updates

HTTP Viewer Promoted

The HTTP viewer, version 3.7.2.286707 was promoted to the de facto release viewer on February 25th. This currently leaves just two RC viewers in the release channel: the Maintenance RC (3.7.2.286708) and the Interest List viewer (3.6.14.285213), both of which should  be rebuilt using the HTTP viewer code base in due course.

Sunshine / AIS Viewer

With only two RCs in the release channel, it is possible the Sunshine / AIS viewer may be moved to release candidate status this week. Given that the server-side AIS code is starting to be enabled on the main grid, this viewer could be on course to reach a release status in week 11.

Group Ban Lists

Baker Linden is currently filing for the server-side code to be deployed to Aditi, which he hopes will happen by the end of the week. In the meantime, he describes the status of the Viewer code as, “testing it for compatibility with old viewers and such. Once that’s stable and I know I didn’t break anything, I’ll start filing for the viewer to become a release candidate.”

Other Items

Region Restart Oopsie

The new on-screen region restart warning, accompanied by a sound and camera shake
The new on-screen region restart warning, accompanied by a sound and camera shake

A slight issue has come to light with the recently implemented new region restart alert, now active in the SL viewer and in the most recent updates to a number of TPVs. Essentially, the sound accompanying the 5-minute countdown (and which is played alongside the camera shake at the top of each minute in the countdown) is actually played in-world rather than locally.

The result is that if there are several avatars close together who are using viewers with the new restart alert code, the noise can either be very loud or something of a mess (particularly if some of those users have opted to set custom warning sounds within their viewer).

The fix is relatively straightforward, and will doubtless be incorporated into an upcoming viewer release. In the meantime, the Firestorm team have implemented their own fix ready for the next release of that viewer due in early(ish) in March, which will be the first version of Firestorm to incorporate the new code.

Pocket Metaverse Users Inadvertently Blocked at Weekend

There were a number of reports over the weekend that users on the iOS Pocket Metaverse third-party client were unable to log-in to Second Life, as a result of their hardware being blocked. This caused a number of forum posts on the subject, such as this one and this one, and some upset on Twitter.

It turned out the client was apparently presenting the wrong information to LL’s servers, triggering the hardware block. On becoming aware of the problem, the Lab immediately set about reversing the blocks, and the matter appeared to be cleared-up by the end of the weekend.

The Pocket Metaverse issue caused some users to complain on Twitter, prompting a resonse from Ebbe Altberg

Kokua 3.7.1.30956: Fitted Mesh and refresh scene option

Posted on by Inara Pey

kokua-logoKokua, the SL and OpenSim v3-style viewer, updated on Tuesday February 18th to version 3.7.1.30956. With it came support for the Lab’s Fitted Mesh solution and the Facebook log-in hotfix.

As well as bringing the viewer up to parity with the Lab’s code base through to 3.7.1, this release also sees a set of updates from the Kokua team, the core of which can be summarised as:

  • The Mac version of the viewer (issued as a test version in January) is now available as a release version with this update, thanks to the help and support of Mac users
  • The Draw Distance slider on the status bar is now turned off by default as new users were apparently confusing it with a volume slider. It can be re-enabled via the debug setting ShowDDSlider (Advanced > Show Debug Settings)
  • The Windows version of Kokua now uses the FmodEx library for music streaming, and incorporates the avatar name in the title bar (port from Firestorm)
  • Opensim variable-sized regions and Aurora Sim regions are now supported
  • A number of issues with the UI have been resolved with assistance from CtrlAltStudio’s Strachan OFarrell.

Refresh Scene

Perhaps the most interesting update to Kokua with this release is a new Refresh Scene feature. This is primarily aimed at mitigating the missing prim issue, and can be accessed through both the Commands and Advanced menus or by pressing CTRL-ALT-SHIFT-R.

The Scene Refrsh option in the Command and Advanced menus
The Scene Refresh option in the Commands and Advanced menus

When selected, the option carries out a number of tasks:

  • Basic Shaders are deselected, increasing the viewer’s frame rate and allowing the viewer to more quickly pull-in the basics of a scene
  • A message is sent to the viewer log, allowing the viewer to run a little longer without the shaders
  • Basic Shaders are re-enabled to complete re-dressing the scene, which should now be correctly rendered.

Other Notes

There have been some reports in the comments following the release notes of issues running the 64-bit Linux version of the viewer on Ubuntu, which are apparently under investigation.

I did encounter initial issues running the viewer on 64-bit Windows using my Crash Test Alt, which saw the viewer repeatedly going non-responsive within a minute or so of logging-in. However, I confess to not having performed a clean install,  so this particular issue could have been as much my end as anything else. When I did perform a completely clean install, the issue went away. So if you do encounter issues, try a clean install, if you haven’t already.

All told, another nicely packaged update to Kokua, one which probably hides a lot more in the way of under-the-hood changes than might at first appear to be the case. The Refresh Scene option is an interesting approach to resolving the missing prim issue, and may well prove to have other benefits in the future as well.

SL projects news week 8/1: server, viewer and log-in issue PSA

Posted on by Inara Pey

My apologies for the late release of this update; things have been a little bit hectic, and I’ve been rushing to catch-up on posts and news.

Server Deployments: week 8 – recap

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

  • As there was no update to the RC channels in week 7, there was no update to the Main channel on Tuesday February 18th.
  • On Wednesday February 19th, all three RCs received a new server maintenance package which comprised the following updates:
    • Fix for BUG-5034 “If an EM restarts a region and then teleports out immediately, the EM will disconnect just after teleport”
    • Fixed a rare case in which e-mails read by LSL scripts immediately after rez or region change would sometimes be missing the message body
    • Fixed some crash modes

The region restart issue (BUG-5034) was described in part 2 of my week 7 report.

Commenting on the e-mail issue during the Server Beta Meeting on Thursday February 20th, Maestro Linden said:

The other bug fix was for some obscure e-mail issue that Kelly found, where e-mails to LSL scripts would be missing their message bodies under very obscure circumstances. Nobody’s filed a bug report about that happening, so maybe nobody ever saw it regularly.

 In this case you’d see the e-mail, and see the subject but not the body. Or rather, I guess the body would be an empty string … I guess you’d only know if you had sent the e-mail yourself.

 According to Kelly, it would only happen during a very narrow time window as the sim was starting up, so I could imagine most people who saw it once just shrugging after the issue didn’t occur a second time.

SL Viewer Updates

  • The Maintenance release RC was updated on Tuesday February 18th to version 3.7.2.286708
  • The HTTP RC was updated on Wednesday, February 19th to version 3.7.2.286707
  • The Google Breakpad RC has been removed from the release channel, having completed this round of tests.

Group Ban Lists

There’s not much more to report here than last week. Commenting on the overall status of the work at the Simulator User Group meeting on Tuesday February 18th, Baker Linden said:

I’m in the last stages of code cleanup and ensuring there aren’t any major bugs (which QA will surely find) and I’m wrapping everything up for deployment to Aditi this week (server-side stuff only right now).

 It’s not clear if the server code did reach Aditi, or whether it may appear in week 9. Commenting on the status at the Server Beta meeting later in the week, Maestro Linden indicated the code was “inching closer to Aditi”, and will be available “as soon as we’re confident that the backend host and simulators are playing nicely. If there’s a bug which is definitely viewer-only, that’s not a blocker for Aditi at all.”

Materials Handling

Scripted Control

The ability to control materials (normal and specular maps) via scripts has been an oft-discussed topic in User Group meetings and the subject of MATBUG-359.  The subject was again raised at the Simulator User Group Meeting on Tuesday February 18th, to which Simon replied, “I’ve been looking into that, and hope to get to it soon, but it keeps getting pushed back with other more immediate issues cropping up.”

One of the concerns with scripted control of materials maps in that if manual changes are made to materials too quickly in the build floater, they will often revert, as if the server is unhappy in receiving  too many quick updates. Commenting on this, Simon added:

That’s an interesting point and something we’ll have to look at after doing the basic scripting change.   If it’s somehow worse than the current scripted texture changes, we’ll have to have some sort of throttle to slow it down.

The question was raised on why normal and specular maps appear to work different to diffuse (texture maps), with the server better able to handle fast changes to textures when compared to normal and specular maps. Simon indicated that both normal and specular maps are handled differently in order to minimise the impact of multiple usage.  Expanding on this is terms of scripted control, he went on:

I was just looking at the materials code, and the complication this has compared to regular textures is how materials have their own layer of special data packaging instead of a just a UUID on a face.  I’m not sure yet how script access is going to thrash that data or not.

There also may be something of a cost / benefit issue within the Lab when it comes to adding scripted control to materials – would the potential uses be broad enough to justify the time required to avoid issues of data thrashing, introducing throttles on updates, etc. Hence Simon asked for some specific examples of where scripted control of materials would be beneficial, so he could carry them back to the Lab’s product managers.

Metabolt set to live on

Posted on by Inara Pey

Metabolt-logoThere have been concerns and rumours circulating about Metabolt, the text-based client for Second Life and OpenSim. The last update occurred in August 2013; the long delay coupled with the recent unavailability of the Metabolt website, fuelled rumours that the client was being discontinued.

However, this is not the case; CasperTech are stepping-in to take over curating the project, as an announcement on the Metabolt website reveals:

Same Viewer. New Opportunities

It was recently announced that the METAbolt project was being discontinued. We are very happy to announce that this has not happened, and instead CasperTech have stepped in to curate and maintain the project.

CasperTech is a leading provider of solutions for content creators within Second Life. We believe that METAbolt will benefit from our strong legacy and foundations.

It is not our intention to commercialise the project, and we will maintain it in the same spirit of open source community collaboration. We do intend, however, to rejuvenate the METAbolt community with active development, support and new innovation. We are very excited by this opportunity, and we hope you are, too!

Please bear with us while we complete the transitional period – we’re working on a new website and will be making our first release of METAbolt soon.

– Casper Warden, CasperTech Ltd.

While the new Metabolt site is being set-up, a link to the download page / source code for the current release of the client is included below the message.

Metabolt: set to continue thanks to CasperTech
Metabolt: set to continue thanks to CasperTech

Metabolt is popular text-based client for users of various types of bot in SL (such as the Pandora Bot), which can be used for a variety of role, such as greeters, automated assistants, etc. As such, the news that the client looks set to continue should be warmly received.
