Server Deployments: week 13 – recap



there was only one update in week 13. The Magnum Rc received a new server maintenance project, comprising:

Crash mode fix.

Fixed a rare case in which certain users were unable to log in ( )

Fix for a case in which multiple scripts in the same prim calling llTakeControls() with heterogenous ‘accept’ and ‘pass_on’ parameters would not receive a control() event correctly in some cases ( )

Updated LSL syntax file to use a new schema (fixes ) related to a viewer in testing and apart of .

SL Viewer

The StatTest viewer was updated on Thursday March 27th to version 3.7.5.288371. This viewer makes one change related to crash statistics gathering has no functional changes compared to the current release viewer (download and release notes).

Also on Thursday March 27th, the Interest List RC returned to the release channel, having been temporarily removed on March 21st due to the number of RCs occupying the channel. The return sees the viewer updated to version 3.7.5.288404 (download and release notes).

Group Bans List

Things have been a little quiet in this of late. speaking at the Server Beta meeting on Thursday March 27th, Baker Linden explained why. “I pushed a new version of the group ban viewer, but unfortunately, it’s still a tad unstable. I don’t know how I managed to mess up the merge this bad … I think I lost some code. Well, I’m sure I lost some code. So I’m trying to go back and fix all that, but it’s coming along.”

The latest versions of the test viewer can be obtained via the links on the Server Beta wiki page. This can be tested on Aditi, and the server-side code in active on Morris, where the Server Beta meetings are held (and the code for which has been updated to prevent people with group ban rights from banning themselves from the group…).

Group Chat

There was a further test of the group chat back-end changes during the Server Beta meeting on Thursday March 27th. This involved around the same number of people as the first test, with some remaining in one location and others moving between regions while chatting.

In both instances, viewer freezes were noted when swapping between the group chat sessions and between local chat and one or other of the group chat sessions. These would last between 2-10 seconds depending on the volume of chat going through the group channel session being swapped to, with the average freeze being around 5 seconds.

Commenting on progress with the work, Simon Linden said:

I’m cautiously optimistic I can increase the performance … which should help reliability. From what I can tell, it just can’t handle the load at times. At a small-scale group chat isn’t that difficult a problem but with possibly 42 groups per online AV, the numbers involved can start getting big … I didn’t write the group chat servers, but am just the lucky guy wading through it now. Like I said, I’m cautiously optimistic I can improve it. A re-write to a new engine would be a pretty large project … and has already been tried once.

Further testing should be progressing to Agni and a large group in week 14.
