The majority of the notes in this update are taken from the TPV Developer meeting held on Friday, August 11th 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. Timestamps in the text below will open the video in a separate window at the relevant point for those wishing to listen to the discussions.
Server Deployments Week #32 – Recap
Please refer to the deployment notice for the week for latest updates and news.
- On Tuesday, August 8th, the Main (SLS) channel was updated with a new server maintenance package (#17.07.27.327933), comprising “additional internal fixes”,
- The scheduled deployment to the RC channels for Wednesday, August 9th has been cancelled due to a back-end data issue which meant the region channel names weren’t being set correctly, so they didn’t start.
[00:54] The Maintenance RC viewer was updated on Wednesday, August 9th to version 220.127.116.118060. This is currently the most likely candidate for promotion to de facto release status. The rest of the LL viewer pipeline remains as at the start of the week:
- Current Release version 18.104.22.1686593, released on May 26, promoted June 20 – formerly the AssetHTTP RC viewer – overview – download and release notes
- Release channel cohorts:
- Project viewers:
- Obsolete platform viewer version 22.214.171.1240847, dated May 8th, 2015 – provided for users on Windows XP and OS X versions below 10.7.
[01:15-01:40 and 4:51-5:33] It is hoped the Alex Ivy 64-bit viewer will be updated in the early part on week #33 (commencing Monday, August 14th). Currently, the viewer is still showing an elevated crash rate for some, for reasons yet to be determined. In the meantime, the Lab is adding further code that will hopefully capture more crash information.
[01:56 and 06:49] The 360-degree snapshot viewer is currently on hold due to people being on vacation at the Lab. This may be a slightly extended delay while resources are diverted to the 64-bit viewer and CEF work.
[14:22-14:34] The Voice viewer is also suffering a high crash rate, also for unknown reasons.
[14:35-14:46] One of the next viewer projects for the Lab is a major re-vamping of the crash reporting and analysis system, which will hopefully make it easier to trace down probable causes for viewer crashes.
[02:15-04:21] The least couple of weeks have seen server-side issues with llHttpRequest. Some of this has been due to low-level library changes that were inherited in updating the simulator code to some of the new components, including the OS itself. Other issues were the result of changes the Lab made at around the same time.
Most of these issues have now been rectified, although there is still some incompatibility issues still to be sorted. There is one further significant update related to this which will be going out on Aditi (the Beta grid), which will be put to the test with the intention of seeing if anything else breaks. A blog post / forum notice will precede this.
Simulator Infrastructure Updates
[08:52-09:28] The Lab is going to be carrying out a lot of simulator infrastructure work over the next two quarters. Efforts will be made to make user-visible updates during this work, but most of the work will be transparent to users, and may result in some performance improvements.
[08:18-08:46] Group notice failures: No work has been put into looking at why some group notices are being dropped. This is currently seen as a lower priority than dealing with issues which can crash simulators.
If an open-source developer implements mirrors that work, and are acceptable from a performance point of view, without unreasonable restrictions on where you can put them and what you can put them on, I at least will be happy to consider the contribution. But I don’t believe that’s possible, and I am assured by graphics developers who know a great deal more about rendering than I do, that it isn’t possible; and that’s why we’re not doing in. So, if you have a miracle worker out there who wants to do a contribution to the viewer – go for it! But since I’d like to get other work done, I’m not going to devote our developers to doing it.
[18:20-18:32] Viewer UI Region / Estate ban list improvements: this work is still pending a developer resource.
[19:10-24:12] Abuse of Setting Home: it has been reported that griefers are able to circumvent being kicked out of a region (TP Home) by moderators if they have home set to that region. The alternative to this is to ban them from the land – but this requires the rights to do so. There are also alleged means to bypass estate bans if the home position is set to the banned region – which should not be possible. If there is a bug allowing this to happen, it needs to be reported with repro steps.
PacMan Stars and Black Stars: the issue of “Pacman stars” (irregularly shaped stars) has been fixed via a contribution by Drake Aconis (Sovereign Engineer). However, the issue of stars appearing as black dots in some daylight windlight settings has yet to be fixed. This may be looked at as a part of the EEP.
