SL project updates 16 6/1: server and viewer

Calas Galadhon; Inara Pey, February 2016, on Flickr Calas Galadhon – Gulf of Lune – blog post

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, 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:, January 15 – formerly the Maintenance RC viewer download page, release notes
  • RC viewer (+ the HTTP / Vivox RC above):
    • Maintenance RC viewer version released on February 2 – 38 updates. fixes and tweaks (download and release notes)

Server Deployments Week 51 – Recap

  • On Tuesday, December 16th, the Main (SLS) channel was updated with the server maintenance package deployed to the three RC channels in week #50
  • There were no deployments to the RC channels.

The end-of-year code freeze / no change window comes into effect from the end of the week, this means there will be no further server updates until January 2015.

SL Viewer

Release Viewer

The Maintenance RC viewer, version, was promoted to the de facto release viewer on Thursday, December 18th. This viewer comprises a solid collection of bug fixes and improvements to many areas of SL, and also includes a range of fixes to previously released changes in the way joint offsets in rigged meshes are handled. Please refer to the release notes for further information.

Experience Keys RC Viewer

On Wednesday, December 17th, the Experience Keys / Tools viewer was updated to release candidate status with the release for version Please refer to my overview of the viewer (written while it was at project viewer status) for information on the viewer.

Further RC Updates

[00:50] As a result of the promotion of the Maintenance RC, both the new Experience Keys RC viewer and the HTTP Pipelining RC viewer are currently being rebuilt to include the Maintenance release code. These updates may appear in the release viewer pipeline on Monday, December 22nd, or they may be held over from release until after the end of the no change window.

Viewer Build Tools Project

[01:41] The new year should also see the first release of a project viewer for Mac and Windows built using the new build tools chain and autobuild process.

Group Chat

The last of the 2014 updates are being deployed to the back-end servers. At the time of the Server Beta User Group meeting, there were just a “few more” hosts that had yet to receive the updates, so things should be completed in short order. These improvement are focused on improving the overall robustness of the service and dealing with overload conditions.

CDN Work

What is being referred to as a “mini CDN” test was carried out on the BlueSteel region on the morning (PDT) of Thursday, December 18th. The test was designed to check a more flexible  CDN configuration that is going to make it easier for  the Lab to deal with fall overs. “It should be invisible normally but lets us have better control of where the viewer gets those mesh and texture assets,” Simon Linden said of the work, which will likely see a formal deployment in the New Year.

Viewer-managed Marketplace (VMM)

[03:53] There was an in-world meeting held on Friday, December 12th to discuss the Viewer-managed Marketplace (notes and transcript).

There should be a summary post from the Lab, covering JIRAs raised on VMM and comments made on the forums, which should be appearing on the current forum thread around the time this update is published. A further feedback meeting is being planned for the New Year.
