SL project updates 2017-4/3: TPVD meeting: 64-bit, Linux

Whimberly, Whimberly; Inara Pey, January 2017, on FlickrWhimberlyblog post

The notes in this update are taken from the abbreviated TPV Developer meeting held on Friday, January 27th, 2017. The video of that meeting is embedded at the end of this update. My thanks as always to North for recording and providing it.

SL Viewer

[01:19] There has been no movement with any of the viewer currently in the various pipelines during the week, leaving the list as:

  • Current Release version:, dated December 1st, promoted December 5th, 2016 – formerly the Project Bento RC viewer
  • Release channel cohorts:
    • Maintenance RC viewer, version, dated January 12th
  • Project viewers:
    • Project Alex Ivy (LXIV), 64-bit project viewer, version for Windows and Mac, dated January 10th
    • 360-degree snapshot viewer, version, dated November 23, 2016 – ability to take 360-degree panoramic images – hands-on review – still pending completion of work on the 64-bit viewer, and no updates expected in the immediate future
  • Obsolete platform viewer, version, dated May 8, 2015 – provided for users on Windows XP and OS X versions below 10.7.

[01:48] There are two more branches for the Maintenance viewer updates in the offing. One is, as per Oz’s stated intent, a branch for rendering only fixes, the second will continue with the regular releases of Maintenance RC viewers with all other general fixes and updates.

64-bit Viewer

[22:55] The number of users on the 64-bit project viewer remains “small”, however, the Lab is pleased with the way most things in the viewer and viewer build process are working. There are still three major areas of work which need to be completed, outside of bug fixes, before the viewer can progress to release candidate (RC) status:

  • 64-bit Havok for OSX: the binaries, etc., have been received from Havok, but have been built using Xcode 8. The Lab is therefore updating the Mac viewer build process to use Xcode 8 so that the Havok code can be incorporated.
  • Updated VLC and CEF support: this is in process, and in the case of CEF, will include a new wrapper (project Dullahan – link for those who are curious about the etymology of Lab project names) which will replace llCEF, making it easier to render web content through the viewer
  • The new viewer installation / update process: this is being overhauled to improve the installation and update of the viewer. In particular, it will include a check to ensure users have actually downloaded the correct version of the viewer for their system. For example, if you are on 32-bit Windows and download the 64-bit version in error, the installer will recognise this, and download and install the 32-bit version for you.

Note the above still only apply to Windows and Mac OSX.

Linux Viewer Status / Future

[30:21] Thus far, the Lab hasn’t progressed very far with Linux 64-bit, beyond building some of the libraries. The aim is still to have the third-party viewer development  / open source community provide a strong level of support for Linux. However, it is recognised that the current way in which the Linux viewer is currently distributed makes it difficult for third-party support to be maintained.

In an attempt to improve things, the Lab is going to try to move away from using a TAR ball method of distribution to providing a .DEB file, which can be installed using standard Debian installation commands. This will involve changes to the Linux build process, which itself may highlight issues in producing the desired .DEB file. Where this is the case, the Lab will look to discuss and resolve issues with the TPV / open source community. It is hoped that this approach will result in a much improved and easier to manage mechanism for Linux viewer builds and distribution.

Other Items

Music Streaming Default Volume

[04:57] The first TPVD meeting for 2017 included a discussion on audio streaming autoplay found in the official viewer, and the problems this can cause new users. As a result of that discussion, the Lab agreed to revisit the default media volume setting in the viewer. This is now under discussion within the Lab.

Voice Issues

[06:06] While there is a Voice update coming down the line, people are reporting increasing Voice disconnection issues (see BUG-41288). Kyle Linden has been looking into the problems to try to identify where issues might reside, and it is a topic for discussion at the next Lab / Vivox meeting, in about a week. Oz Linden is also improving the code in the viewer to better monitor and report on Voice connections and issues so that they can be more easily identified; these updates will hopefully be in the upcoming Voice viewer.

Environment Maps

[12:53] At the end of the last TPV meeting, there was a convoluted discussion on environment maps and potential limitations. A JIRA feature request – STORM-2146 – has now been raised, outlining the specific issues with the environment maps, and what can be done to improve them to provide things like simulated environment reflections.  Acknowledged as being a prime example of a really good feature request in terms of level of explanation given (including mitigating risk of content breakage), the topic was put aside for detailed discussion at a later date, to allow this meeting to focus on the 64-bit viewer and Linux.

Server-side Group Chat “Opt Out”

Firrestorm has a viewer-side implementation to mute all chat from a group, but a server-side capability is being requested

Firrestorm has a viewer-side implementation to mute all chat from a group, but a server-side capability is being requested

[17:53] This is a request to provide support for “opting out” (muting) from group chats without necessarily having to wait for it to start & closing the window (e.g. via a right-click option on the group list or in the group profile – a method taken by Firestorm in providing viewer side support for the capability).

The Lab is aware of numerous requests for such an option, together with numerous and different suggestions on how it might be implemented. Because of this, no firm decision has been made on whether or not to add such a capability, managed server-side, has been taken.

The advantage of server-side support is that rather than having the viewer just discard incoming messages seen as “unwanted”, the server will not send them in the first place. This is very much what the Lab would like to achieve, were the capability to be added.

E-mail Improvements

[39:37] Changes are coming to the way in which e-mails are managed / distributed by the Lab. Please see my separate report on what this means and verifying you e-mail address, if you have not already done so.

SL Wiki Editing and JIRA Viewing

[49:03] The Ls Wiki remains closed to general editing. Users with a genuine need to edit wiki pages they have previously helped maintain or have created, should file a support ticket or raise a JIRA requesting the are granted Edit rights, and why they are requesting them. The Lab is now maintaining a white list of approved users.

Similarly, TPV developers and open source contributors who cannot view JIRAs related to their work, etc. (“Permission Violation”), should e-mail Oz Linden to request broader access to the system.
