The following notes are taken from the TPV Developer meeting held on December 13th, 2019. A video of the meeting is embedded below, my thanks to Pantera for recording and providing it. As always:
- Time stamps are given with links that will open the video at the appropriate point in a separate browser tab for reference.
- Core points of the meeting are listed below. Other subjects of lesser import may have been discussed, please refer to the video.
SL Viewer News
Note: the comments below also include updates given at the Content Creation User Group meeting of December 12th.
- Copy / Paste viewer project vewer updated to version 18.104.22.1683365 on December 9th.
- The Wassail RC viewer, version 22.214.171.1243275, was promoted to de-facto release status on Thursday, December 12th. This was likely the last viewer promotion to release status for 2019.
The rest of the current viewer pipelines remain as follows:
- Release channel cohorts:
- EEP RC viewer, version 126.96.36.1992771, dated November 20th.
- Project viewers:
- Copy / Paste viewer, version 188.8.131.523365, dated December 9th.
- Legacy Profiles viewer, version 184.108.40.2060836, dated September 17th. Covers the re-integration of Viewer Profiles.
- Project Muscadine (Animesh follow-on) project viewer, version 220.127.116.110473, dated September 11th.
- 360 Snapshot project viewer, version 18.104.22.1689111, dated July 16th.
General Viewer Notes
- It is thought the Legacy Profiles viewer could be next in line for promotion to defacto release status. However, this viewer is still awaiting the release of an update that integrates the profile feed into the viewer.
- There are reportedly multiple issues with the Copy / Paste project viewer, some of which are UI related – no specific bug report reference to relay here at present, though.
- In addition, and awaiting surfacing / further work internally, are further Maintenance viewers and improvements to the mesh uploader.
Mercurial to Github Migration
Bitbucket, used to manage viewer repositories) will be sunsetting support for Mercurial in early 2020. Because of this, Linden Lab has now started migrating their viewer repositories from Mercurial to Git on Bitbucket.
- This means the pace of viewer updates might slow down while this work is in progress.
- A document outlining the steps in migration has been provided specifically for TPVs to allow them to keep in sync with how LL main the viewer code and its branches. See: Viewer Repository Migration (Google Docs).
- This is not the only way for TPVs to manage their own repositories, but it is the one that LL recommend for those wishing to reflect how LL manages things.
- [36:48-41:15] Thus far, the Lab have not run into problems in making the migration. It was also pointed out that:
- There are a number of cheat sheets out on the web for TPVs and self-compilers to make / understand the switch from Mercurial to Git.
- There will be fewer repositories used by LL for the viewer, as Git provides better support for branching and better matches the LL build process.
Viewer Updates for 2020
- Two viewer updates that will be surfacing in 2020 are Name Changes and Premium Plus.
- With regards to Name Changes, TPVs many what to consider migrating people’s settings and chat histories when they change their names, as all of this information is stored in a local folder / directory based on the avatar name.
- This could take the form of switching to using the avatar key UUID, although this isn’t necessarily user-friendly when looking at log files, etc.
Deprecating Windows 7 Support
- Windows 7 officially reaches its end of life on January 14th, 2020. After this date, patches and security updates, etc., will no longer be provided, and the company is unlikely to provide any support.
- As a result of this, it is very Linden Lab will cease officially supporting Windows 7 after that date. While users will still be able to log-in to Second Life on PCs running Windows 7:
- They will not receive assistance from LL support should they encounter problems.
- Viewer updates from the Lab will no longer be tested against Windows 7 prior to release.
- Bugs reported against Windows 7 that cannot be reproduced using Windows 8 or Windows 10 will not be investigated.
- Around 12% of SL users are running Windows 7, and this applies to them.
- Obviously, given Microsoft is ending Windows 7, the recommendation is for users to upgrade to Windows 10.
Linden Lab No Change Window
The 2019 end-of year No Change window is from Friday, December 20th 2019 through Thursday, January 2nd 2020. During this time there will be no simulator or official viewer updates, and TPVs are asked also not to make releases during this period in case they accidentally cause support or operational issues for LL.
- [7:15-9:02] The updates to the viewer build process (to support Visual Studio 2017 and Xcode 10.3) are in a bug hunting mode at the moment, and so will see light of day in early 2020.
- It is possible that work on updating to VS 2019 might commence later in 2020.
- [9:07-11:23] One of the projects awaiting the deployment of the new build process is updates to the Chrome Embedded Framework (CEF) responsible for handling media in the viewer. It is hoped that when these updates can be provided within the viewer they will help with media support playback and eliminate at least some problems.
- These updates should help with MP4 playback as more codecs are being added – although again, MP4 is a container with flavours rather than a specific format, so all flavours may not play back equally.
- [12:08-19:00] Discussion on Bugsplat, the crash reporting tool. This is probably outside the interest of most users, so is not listed below – please refer to the video.
- [22:40-24:00] Discussion on a Firestorm OpenSim release. Again, this probably not relevant to the majority of readers of the blog (and I’ll be covering it separately as and when it appears anyway), so again – please refer to the video.
- [32:04-32:40] BUG-227179 – All off-line inventory offers from scripted objects are STILL lost: this bug is still awaiting work.
