[11:09 AM PT]  Ubit Umarov: welcome to another weekly meeting :)
[11:09 AM PT]  Ubit Umarov: During last week there where code changes commited
[11:10 AM PT]  Ubit Umarov: i did spent sometime playing with dotnet 6.0 migration issues
[11:10 AM PT]  Ubit Umarov: in fact got my first win11 BSOD in the process
[11:11 AM PT]  Andrew Hellershanks: Bah. Was deep in to some coding of a threaded interpreter language. Wasn't looking at the clock.:P
[11:12 AM PT]  Ubit Umarov: but with several hacks i did manage to compile and run a region in windows compiled and mostly using .net6.0 runtime
[11:12 AM PT]  Andrew Hellershanks: Hello, everyone.
[11:12 AM PT]  Ubit Umarov: in the process i had to remove Xengine, that does depend on features no longer present in dotnet
[11:14 AM PT]  Ubit Umarov: also some of out threading contol lost the ability to stop threads, something dotnet did remove, because they decided it is bad
[11:14 AM PT]  Ubit Umarov: so there is no way to stop a  thread stucked anywhere and try to recover from it
[11:15 AM PT]  Ubit Umarov: in a automatic way..
[11:16 AM PT]  Ubit Umarov: well can understand why they removed, seems they actually never did it right, if that is even possible..
[11:16 AM PT]  Ubit Umarov: hopefully we may live without it..  but it is another lose..
[11:17 AM PT]  Ubit Umarov: i did compile out main code in .net6.0,  warp3d and libomv
[11:18 AM PT]  Ubit Umarov: adding 2 extra dlls..  one to extend the support for image/bitmap to .net6, other to have a component needed for log4net, that they also removed, but still possible to add back
[11:19 AM PT]  Ubit Umarov: so as i said i did run a basic standalone on sqlite, even did load a oar and tested a car under yengine and ubode
[11:19 AM PT]  Ubit Umarov: the tested on WSL, the windows linux "emulator"
[11:20 AM PT]  Ubit Umarov: first time i fired opensim i got my first win11 BSOD
[11:21 AM PT]  Andrew Hellershanks: :)
[11:21 AM PT]  Ubit Umarov: thing mostly a WSL issue... i was out of ram, and WSL did blowup instead of normal use of swap space etc..
[11:21 AM PT]  Ubit Umarov: think..
[11:22 AM PT]  Ubit Umarov: othen ofc opensim just failed to load sqlite low level dlls
[11:22 AM PT]  Ubit Umarov: showing that we need to rewairte he entire way how dlls are loads
[11:22 AM PT]  Ubit Umarov: dotnet, fails to do what mono does fien
[11:22 AM PT]  Ubit Umarov: fine
[11:23 AM PT]  Ubit Umarov: so im stil far to check if the image code does still work in linux  on dotnet6.0
[11:24 AM PT]  Ubit Umarov: they did remove it, but they added a flag to allow it again. if one adds the extra dlls
[11:24 AM PT]  Ubit Umarov: that are ofc diferent from the windows ones...
[11:25 AM PT]  Ubit Umarov: making cross platform even more fun
[11:25 AM PT]  Andrew Hellershanks: :)
[11:26 AM PT]  Ubit Umarov: so.. lots of work to get less features and getting into a lot more unreliable software base
[11:27 AM PT]  Ubit Umarov: ofc this is also only try to compile and run the software
[11:27 AM PT]  Ubit Umarov: hard to tell and fix all the hidden breaking changes they made all over the code base
[11:28 AM PT]  Ubit Umarov: soll well that was some code work during last week...  a very frustrating experience
[11:29 AM PT]  Ubit Umarov: meanwire there was a new FS release
[11:30 AM PT]  Ubit Umarov: seems working, just profiles images fail to load in full resolution a lot
[11:30 AM PT]  Ubit Umarov: told Beq abotu it, she may look
[11:30 AM PT]  Ubit Umarov: meanwhile the had some work on profiles for the next release
[11:31 AM PT]  Andrew Hellershanks: I downloaded the latest FS for SL and OS this past week. I haven't used either of them much. What I'm noticing right now is that my CPU load seems lower than before.
[11:31 AM PT]  Ubit Umarov: FS did merge new LL code for profiles that did kill all profiles for opensim
[11:32 AM PT]  Ubit Umarov: replacing all the lludp based protocol by new ( BAD)  http caps based
[11:33 AM PT]  Ubit Umarov: Beq was busy putting back support for opensim, and last time we talked, 2 days ago? she had it mostly done
[11:33 AM PT]  Ubit Umarov: meanwhile i did look to the new profiles protocol,, and it is just really BAD
[11:34 AM PT]  Ubit Umarov: not easy to jsut add it, without changes from region code up to grid databases apis
[11:35 AM PT]  Ubit Umarov: since Beq did recover the lludp,  guess i will not try to add that new nonsense ll protocol
[11:36 AM PT]  Ubit Umarov: see..  change from lludp is change, means use of TCP that is a lot slower and heavy
[11:36 AM PT]  Ubit Umarov: means changign from a very compact information serielization, to LLSD based one, and XML based oen
[11:37 AM PT]  Ubit Umarov: that means that 90% of the data payload is XML support only..
[11:37 AM PT]  Ubit Umarov: but in this case they made it worse
[11:37 AM PT]  Ubit Umarov: in profiles, a packet did include several changes
[11:38 AM PT]  Ubit Umarov: like abotu text, UUIDs if pictures etc etc
[11:38 AM PT]  Ubit Umarov: so most of the edit on he profile was local on viewer, and only commited to region at end
[11:39 AM PT]  Ubit Umarov: and sent all in a nice packet
[11:39 AM PT]  Ubit Umarov: now the new procole makes a CAP call per item changed...
[11:39 AM PT]  Ubit Umarov: as we do the changess
[11:40 AM PT]  Ubit Umarov: ir as soon we change about test, it sends it to server..
[11:40 AM PT]  Ubit Umarov: the uuid of a pocture..
[11:40 AM PT]  Ubit Umarov: etc
[11:40 AM PT]  Ubit Umarov: picture
[11:41 AM PT]  Ubit Umarov: that is a extra overhead on comms
[11:41 AM PT]  Ubit Umarov: and ofc all out code from region to grids only handles that packet with all information
[11:42 AM PT]  Ubit Umarov: so we would need to add APIs to all the tine changes all over the code base
[11:42 AM PT]  Ubit Umarov: (ine == tiny)
[11:43 AM PT]  Ubit Umarov: this does not include things like pics, classified etc
[11:43 AM PT]  Ubit Umarov: they forgot abotu those and they are still lludp
[11:44 AM PT]  Ubit Umarov: well.. so it is possible to support this changes,  btu a lot of work for absulutly no gain
[11:45 AM PT]  Ubit Umarov: since Bq did restored old API; other viewers can do it also, so i will not try to add those changes, for now at least
[11:46 AM PT]  Ubit Umarov: some more as expected as LL find more things usin lludp and moves to http waste
[11:46 AM PT]  Ubit Umarov: well this are last week code news
[11:47 AM PT]  Ubit Umarov: what abotu you.. what news do you have?
[11:47 AM PT]  Andrew Hellershanks: Thank you for that summary of the past week, Ubit. Was a busy week.
[11:48 AM PT]  Andrew Hellershanks: Nothing new on my end as I was still working on code needed for an industry trade show that started yesterday.
[11:50 AM PT]  Andrew Hellershanks: We have a few less people here today compared to our usual complement. Does any one have any questions or comments for today?
[11:52 AM PT]  Andrew Hellershanks: Are we going to finish early for a change?
[11:53 AM PT]  Jamie.Jordan @grid.kitely.com:8002: looks like
[11:54 AM PT]  Andrew Hellershanks: I should have some time to do some more testing on FS this coming week. I want to check where the latest FS really has lowered the CPU load.
[11:55 AM PT]  Andrew Hellershanks: My frame rate also seems a little higher than it was last week.
[11:55 AM PT]  Ubit Umarov: yes las fs release does include some performance changes ll did
[11:55 AM PT]  Ubit Umarov: on the rendering etc
[11:56 AM PT]  Andrew Hellershanks: Yes, I read that in the release notes. It does appear to have made a noticeable difference on my machine.
[11:56 AM PT]  Ubit Umarov: yeah
[11:56 AM PT]  Ubit Umarov: sad teh profiles images
[11:56 AM PT]  Jamie.Jordan @grid.kitely.com:8002: nine too
[11:56 AM PT]  Ubit Umarov: sad..
[11:57 AM PT]  Ubit Umarov: hopefully Beq or other will find why and fix,
[11:57 AM PT]  Andrew Hellershanks: My profile image came in right away and looks ok.
[11:57 AM PT]  Ubit Umarov: yeah it is more on load conditions
[11:57 AM PT]  Ubit Umarov: also at SL
[11:58 AM PT]  Ubit Umarov: maybe changes on fetch priorities and timeouts
[11:58 AM PT]  Andrew Hellershanks: We can provide further reports about the latest FS next week.
[11:59 AM PT]  Ubit Umarov: only looked to one or 2 of the new features and they seem to work here also
[12:00 PM PT]  Andrew Hellershanks: We are at the top of the hour. Time to call this meeting to a close. My cat will be happy. She is meowing at me. :)
[12:00 PM PT]  Andrew Hellershanks: Thank you all for coming. See you again next week.
