2023 SL SUG meetings week #16 summary

Burrow Wood County, February 2023 – blog post† 

The following notes were taken from the Tuesday,  April 18th Simulator User Group (SUG) meeting. They form a summary of the items discussed and is not intended to be a full transcript. A video of the entire meeting is embedded at the end of the article for those wishing to review the meeting in full – my thanks to Pantera for recording it.

Server Deployments

  • On Tuesday, April 18th, the SLS Main channel servers were updated with simulator release 579248, previously deployed to the RC channels. This means the doubling of linkset data memory (to 128KB) and the three LSL functions for strided list management – llList2ListSlice(), llSortListStrided(), and llListFindListStrided() – are now grid-wide.
  • On Wednesday, April 19th, simhosts on the RC channels will be restarted, but there will not be any new deployments to them.

Upcoming Simulator Releases

  • It is still hoped to get the server-side support for PBR materials to at least one RC channel – Preflight, with the potential it might also go to Snack as well – but there was no ETA on this at the time of the meeting. Currently, it remains with LL’s QA team.

Viewer Updates

No official viewer updates at the start of the week, leaving the pipelines as:

  • Release viewer: Maintenance R viewer, version, dated March 28, promoted March 30th.
  • Release channel cohorts (please see my notes on manually installing RC viewer versions if you wish to install any release candidate(s) yourself).
    • Maintenance T RC viewer, version, April 6th.
    • Performance Floater / Auto FPS RC viewer updated to version, April 4th.
    • Maintenance S RC viewer, version, March 31st.
  • Project viewers:
    • PBR Materials project viewer, version, April 10 – This viewer will only function on the following Aditi (beta grid) regions: Materials1; Materials Adult and Rumpus Room 1 through 4.
    • Puppetry project viewer, version, December 8, 2022.

In Brief

  • llGetAgentInfo received a new flag – AGENT_AUTOMATED – in week #15, however, the simulator side has et to be released; it is currently in a maintenance simulator support which may go to QA for testing in week #17.
    • This raised concerns of whether or not llGetAgentInfo was the right place for this flag, and whether it could result in the dataserver being spammed with requests from people wanting to know if visitors to their land were avatars or scripted agents. However, as Rider Linden pointed out, the simulator already has information on scripted agent, so there is no requirement for the simulator to query the dataserver.
    • See the video for the broader discussion on when the flag for a scripted agent is propagated across the grid.
  • There was a general discussion on possible LSL enhancements. This included:
    • Possible improvements to notecard handling by LSL (e.g. searching notecards – e.g. BUG-4906 -, faster notecard reading, a safe means of sending back the contents of a notecard so a script doesn’t need to build a web page on the fly / read the entire contents of the notecard into memory).
    • HTTP response expansion.
  • Objects rezzing objects: it has been noted that if an object is set to rez other objects (e.g. say a “crate dispenser” which might be used as a visual enhancement to Get The Freight Out to simulate cargo loading), the rezzing tends to work perfectly when the rezzing object’s owner is present, but can experience issues when the owner is not present.
    • This tends to occur if rezzing within the land is restricted to Group membership, and object owner did not correctly set their active group prior to placing out the rezzing object.
    • As the owner’s group is checked when present, this allows the rezzer to work correctly, hence why the problem only surfaces when they are absent.
  • For all other discussions, please refer to the view below.
