Server Deployments

At the time of writing there was no server release thread, I’ll update this article should one surface. The following notes are directly from the Simulator User Group.

  • On Tuesday, January 29th, 2019 the SLS (Main) channel was not update, and remains on server maintenance package 19#, comprising logging to gather baseline information on simulator performance in various areas of interest together with additional logging.
  • On Wednesday, January 30th, 2019 the RCs are likely to be updated as follows:
    • BlueSteel will hopefully receive an update to the EEP code. However, this is dependent on Rider Linden resolving a bug that is currently blocking EEP progress. This causes the time on a EEP region to become “stuck”.
    • Magnum and  / LeTigre will receive a server maintenance package, details undefined; the other should receive an update with internal changes.
  • There is currently a small Cake RC on Agni that is being used to iron out some transient network issues with the newest server operating system update, prior to it being move to a full RC for testing. Cake may grow a little larger before this happens.

SL Viewer

There have been no updates to the current official viewers to start the week, leaving the pipelines as follows:

  • Current Release version, dated December 5, promoted December 13. Formerly the Spotykach Maintenance RC viewer – No Change.
  • Release channel cohorts:
    • BugSplat RC viewer, version, January 23. This viewer is functionally identical to the current release viewer, but uses BugSplat for crash reporting, rather than the Lab’s own Breakpad based crash reporting tools.
    • Estate Access Management (EAM) RC viewer, version, January 23.
    • Love Me Render RC viewer, version, January 16.
  • Project viewers:
  • Linux Spur viewer, version, 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, May 8, 2015 – provided for users on Windows XP and OS X versions below 10.7.

Misc Items

Mesh asset UUID flipping

Being able to flip between mesh objects via script used to be possible in SL. However, it was blocked as it was being used as a means to animate meshes – but not very efficiently (the option places a lot of strain on the asset and physics server).

Recently, there have been requests to re-enable the capability because “now we have Animesh, there’s no need to flip this way.” There are also some use-cases that could benefit from the capability – such as being able to provide customisation options to customers who can then use a scripted mean to add them.

However, as Oz Linden pointed out, the availability of Animesh doesn’t necessarily negate mesh UUID flipping being abused. There is also a risk that the ability could be used to enable IP theft, and the approach – as noted – doesn’t really fit with the current SL design due to things like the asset load, etc. Ergo, it is highly unlikely to be allowed.

SL QA Engineer

If you’re a QA engineer and in the San Francisco  / Bay area, you might be interested in a QA job at Linden Lab working on Second Life.
