[11:00] Andrew Hellershanks: Hello, Ubit and Vincent. [11:01] Andrew Hellershanks: Hello, Michael [11:01] Selby.Evans @grid.kitely.com:8002: hi everyone [11:01] MichaelOmega ChristopherGeode whispers: Hello! [11:01] Andrew Hellershanks: Hello, Orbert [11:01] Orbert.Tatham @hg.zetaworlds.com:80: Hello, folks [11:02] Orbert.Tatham @hg.zetaworlds.com:80: Hey, Andrew [11:02] MichaelOmega ChristopherGeode: Love the greeting, wife and I just re-watched Lucy last night :)) [11:02] Andrew Hellershanks: Good movie. [11:02] Andrew Hellershanks: Hey, Kayaker [11:02] Kayaker Magic: Hello all! [11:03] Ubit Umarov: hi [11:03] MichaelOmega ChristopherGeode: How's everyone been? been so buried for so long i've missed a lot [11:03] MichaelOmega ChristopherGeode: hey Ubit! [11:04] Andrew Hellershanks: np, Michael. We still meet her on Tuesdays so just drop by when you can. [11:05] MichaelOmega ChristopherGeode: need to get my phone attendance capacity back up & running so I dont have to make it back here [11:05] Andrew Hellershanks: If Christmas, New Years day, or the day befare those days happens to be a Tuesday we may skip meeting then. [11:06] MichaelOmega ChristopherGeode: I didn't even get time to prepare a presentation this year :( [11:06] Andrew Hellershanks: Michael, um... ok. I don't understand what you just said. [11:07] Andrew Hellershanks: You have been presenter at the OSCC in past years? [11:07] MichaelOmega ChristopherGeode: yes [11:07] Andrew Hellershanks nods [11:07] MichaelOmega ChristopherGeode: under Michael Christopher [11:07] Andrew Hellershanks: That's coming up soon. It is the weekend after this one coming up. [11:07] MichaelOmega ChristopherGeode: im the one that presented from inside the tornado zone last year lol [11:08] Andrew Hellershanks: That's dedication to your commitments. [11:08] MichaelOmega ChristopherGeode: my word is gold ;) [11:09] Ubit Umarov: well about last week code changes.. [11:09] Ubit Umarov: hmm none it seems :) [11:10] Ubit Umarov: onl some more work on the dotnet6 branch [11:10] Ubit Umarov: i also did create a dotnet6 branch on out fork of libopenmetaverse [11:11] Ubit Umarov: and did update it with the changes i made to it so far [11:11] Andrew Hellershanks: Good idea. [11:11] Ubit Umarov: it is still a bit "hard" to comple [11:11] Ubit Umarov: complie [11:12] Ubit Umarov: parts of with with only compile for windows now [11:12] Ubit Umarov: because dotnet does not include parts it needs like win forms [11:13] Ubit Umarov: for other OS other then windows [11:13] Ubit Umarov: theis means the project files need some hand tunning to set the target platform to windows [11:14] Ubit Umarov: once that is done, all should compile (on vs on windows ) [11:15] Ubit Umarov: the 4 files needed for opensim shoudl compile as is, even if there is a ton of errors relative to the other files.. [11:15] Ubit Umarov: their are at my repo and at bitbucke [11:15] Ubit Umarov: https://bitbucket.org/opensimulator/ [11:16] Ubit Umarov: namely [11:16] Vincent.Sylvester @hg.zetaworlds.com:8002: Only compile on Windows, but Microsoft loves linux /s [11:16] Ubit Umarov: https://bitbucket.org/opensimulator/libopenmetaverse/src/master/ [11:16] Andrew Hellershanks: :) [11:16] Ubit Umarov: there is no forms for linux i thing [11:17] Ubit Umarov: ms is making a new GUI code fro all pratforms calles MUI or something [11:17] Ubit Umarov: https://bitbucket.org/opensimulator/libopenmetaverse/commits/ [11:17] Kayaker Magic: pratfall on the platform [11:18] Ubit Umarov: is some very compacted changes on it [11:18] Orbert.Tatham @hg.zetaworlds.com:80: MAUI is a bit of vaporware so far [11:18] Andrew Hellershanks: Forms always makes me think of something GUI related. Where does it factor in to the backend? [11:18] Ubit Umarov: like play witgh some SIMD (sse) code on UUIDs. [11:19] Ubit Umarov: things like [11:19] Ubit Umarov: Vector128<byte> input = Unsafe.As<char, Vector128<byte>>(ref Unsafe.AsRef<char>(val)); + Vector128<byte> upper = Ssse3.Shuffle(input, Vector128.Create(0, 4, 8, 12, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff)); + Vector128<byte> lower = Ssse3.Shuffle(input, Vector128.Create(2, 6, 10, 14, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff)); +.... [11:19] Ubit Umarov: :) [11:20] Andrew Hellershanks: That certainly feels unsafe. [11:20] Ubit Umarov: a uuid parse with that is done in abotu 12.5ns versus to abotu 35ns with previus code [11:20] Ubit Umarov: and also around 35ns with ms Guid.. [11:20] Ubit Umarov: but a Guid IS not a UUID [11:20] Ubit Umarov: well overdetails :) [11:21] Ubit Umarov: not mushc gain .. as you see,, but well gain is gain [11:21] Ubit Umarov: uuid to string also uses simd now [11:21] Ubit Umarov: simlilar preformance gain [11:22] Ubit Umarov: and performance [11:23] Ubit Umarov: well at least the need changes for libomv to work under dotnet6 are stored also outside my disks :) [11:24] Ubit Umarov: ( you can applause now ... ) [11:24] Ubit Umarov: ;) [11:25] Ubit Umarov: danng.. :) [11:25] Andrew Hellershanks: I don't think I have any applause gestures in this grid. [11:25] Ubit Umarov: :) [11:25] MichaelOmega ChristopherGeode whispers: :)) [11:25] Andrew Hellershanks: /app2 [11:25] Andrew Hellershanks: (¯`v´¯) (¯`v´¯) [11:25] Andrew Hellershanks: `*.¸.*´ `*.¸.*´ [11:25] Andrew Hellershanks: ¸.•´¸.•*¨) ¸.•*¨) (`'·.¸(`'·.¸ A P P L A U S E¸.·'´) ¸.·'´) (¨*•.¸ (¨*•.¸`•.¸ [11:25] Andrew Hellershanks: (¸.•´ (¸.•´ .•´ ¸¸.•¨¯`• •`¯¨• ¸¸ `•. `•.¸) `•.¸) [11:25] Andrew Hellershanks: ok, I do. :) [11:26] Ubit Umarov: thy thy :) [11:26] Andrew Hellershanks: yw :) [11:26] Andrew Hellershanks: Thank you for the progress report. [11:26] Andrew Hellershanks: Hello, Selby [11:27] Andrew Hellershanks: I would have greeted you earlier but your chair was behind my chat window. [11:27] Vincent.Sylvester @hg.zetaworlds.com:8002: I really have to get stuck in and get those tests back working on dotnet, though I seemingly can't even fix them up properly on mono at the moment [11:27] Vincent.Sylvester @hg.zetaworlds.com:8002: Talking to Andrew last couple days trying to make sense of a strange test failure, am still no further with that, things keep popping up so I have little time [11:27] Vincent.Sylvester @hg.zetaworlds.com:8002: It's like trying to herd cats [11:27] Ubit Umarov: you did took dependency i xengine already? [11:28] Ubit Umarov: ..on... [11:28] Vincent.Sylvester @hg.zetaworlds.com:8002: It's a test that uses the mock script engine [11:29] Ubit Umarov: well as i sa said on previus meetings tests are not on my priority list currently [11:29] Ubit Umarov: i fact i have no machine where to run them [11:29] Ubit Umarov: possible could use github actions [11:29] Vincent.Sylvester @hg.zetaworlds.com:8002: Before we can even attempt to run them first have to figure out the prebuild so they don't mess up the build order and fail to build [11:30] Ubit Umarov: but those do have cpu time limit on free accounts [11:30] Vincent.Sylvester @hg.zetaworlds.com:8002: Then it's changing them up for the new nunit3 or 4 or whatever [11:30] Ubit Umarov: i did set them only do compile on master [11:30] Ubit Umarov: also no tests [11:31] Vincent.Sylvester @hg.zetaworlds.com:8002: I am still fixing up things in mono just to have a baseline to work with [11:31] Ubit Umarov: yabn not even sur ei can mk github accept nunit2.x tests [11:31] Ubit Umarov: ( for master ) [11:31] Ubit Umarov: don't thing dotnet will accept nunit2 either [11:32] Vincent.Sylvester @hg.zetaworlds.com:8002: Well I don't yet know how I will make jenkins run nunit4 either [11:32] Vincent.Sylvester @hg.zetaworlds.com:8002: So a work in progress, but I value tests, they have had uses in the past [11:32] Vincent.Sylvester @hg.zetaworlds.com:8002: If only for minor regression testing [11:32] Vincent.Sylvester @hg.zetaworlds.com:8002: All in time, first need to get this damn notecard test to stop being a princess [11:33] Ubit Umarov: on ocasion tests did spot my typos :) [11:33] Ubit Umarov: so some are useful [11:33] Vincent.Sylvester @hg.zetaworlds.com:8002: Or missing files or casts, the codebase is complex, can't always find all the cases [11:34] Ubit Umarov: well compiler spots most of those [11:34] Vincent.Sylvester @hg.zetaworlds.com:8002: Last thing tests caught was a problem with serializations being dependent on system locale, causing issues with decimals [11:35] Vincent.Sylvester @hg.zetaworlds.com:8002: Though that only shows up on tests, runtime works fine [11:35] Ubit Umarov: possible a bug on tests ;) [11:36] Vincent.Sylvester @hg.zetaworlds.com:8002: Bit like visual studio complaining about naming schema and so on, minor things in terms of code quality [11:36] Vincent.Sylvester @hg.zetaworlds.com:8002: I just always like to pay attention to that, less warnings make it easier to spot the really bad ones [11:36] Andrew Hellershanks: Hello, Cuga [11:36] MichaelOmega ChristopherGeode: hi cuga [11:37] Vincent.Sylvester @hg.zetaworlds.com:8002: Not seeing the forest for all the trees kinda thing [11:37] Cuga.Rajal @rajal.org:9000: Hello, sorry late. Nothing new here, just wanted to sit in. [11:37] Andrew Hellershanks: Vincent, have you put in debug messages at the start and end of the subroutines to see if that helps narrow down where it is hanging up? [11:37] Andrew Hellershanks: np, Cuga. [11:38] Vincent.Sylvester @hg.zetaworlds.com:8002: That's my next step, I been reading other tests today so see if anything looks vastly different that might explain what is going on [11:38] Ubit Umarov: oh i also did commit cuga dlls for M1 [11:38] Cuga.Rajal @rajal.org:9000: ahh ok [11:38] Vincent.Sylvester @hg.zetaworlds.com:8002: I also tried to combine the test that is stuck with the one that runs before it, hoping it just a cleanup issue, but no dice [11:38] Vincent.Sylvester @hg.zetaworlds.com:8002: Poking at it until it throws another error [11:38] Ubit Umarov: ofc it they work or not is another story ;) [11:39] Andrew Hellershanks: Vincent, ok. I only noticed one difference in the set up for the NC test that I mentioned the other day but it may not have anything to do with the issues you are experiencing. [11:39] Ubit Umarov: that was part for my dllmap support code [11:40] Ubit Umarov: think i told about it last week? [11:40] Vincent.Sylvester @hg.zetaworlds.com:8002: Unfortunately from reading the documentation I have not found a way to make the test timeout and just repeat if it does, timeout seems a hard fail [11:41] Andrew Hellershanks: I will mention that Vincent said the tests only seem to fail on occasion when run by Jenkins. [11:41] Vincent.Sylvester @hg.zetaworlds.com:8002: I make a code change they run three times or so then fail, just getting stuck until build timeout [11:42] Vincent.Sylvester @hg.zetaworlds.com:8002: Bewildering [11:42] Ubit Umarov: in our box several tests also fail just because mysql timeouts [11:42] Ubit Umarov: when the box is overloaded [11:42] Ubit Umarov: i had to extend some fixed wait times on several to the rudce chance of that [11:42] Vincent.Sylvester @hg.zetaworlds.com:8002: I added a bunch of asserts to the test to make sure the setup has worked and those pass, so I guess that part is fine, leaving the subroutines [11:43] Vincent.Sylvester @hg.zetaworlds.com:8002: On mono branch at least I got the script engine tests back in, for both engines and the general independent tests, performance tests, up to spawning thousands of NPCs and 200000 objects [11:44] Vincent.Sylvester @hg.zetaworlds.com:8002: Minor changes to get that stuff working, thankfully visual studio still has a working test adapter [11:44] Ubit Umarov: well on mono branch they where there [11:44] Ubit Umarov: well ok except the ones i just killed :P [11:45] Vincent.Sylvester @hg.zetaworlds.com:8002: I think it was somewhere around 300 tests, I have managed to get over 500 working now [11:45] Vincent.Sylvester @hg.zetaworlds.com:8002: Well apart from that particular one heh [11:45] Vincent.Sylvester @hg.zetaworlds.com:8002: If I restart jenkins after each build it's fine, but course that's not exactly ideal lol [11:46] Ubit Umarov: well sadly a few are just plain wrong, or useless [11:46] Ubit Umarov: as i said, tests should not me made by same coder [11:47] Ubit Umarov: but by other using higher level abstration on how something must be [11:47] Ubit Umarov: most our tests just test how that code did this or that.. [11:47] Ubit Umarov: that coder.. [11:48] Ubit Umarov: and on several cases that was.. well not correct [11:48] Ubit Umarov: wle rome also took sometime to build.. [11:48] Andrew Hellershanks: :) [11:49] Vincent.Sylvester @hg.zetaworlds.com:8002: Some of the more abstract things are a piece of work to understand [11:49] Vincent.Sylvester @hg.zetaworlds.com:8002: Only new test I managed to write thus far was running a LSL spec test script and recording the results [11:49] Vincent.Sylvester @hg.zetaworlds.com:8002: Course that's crude in basically setting up an entire scene to do so [11:50] Vincent.Sylvester @hg.zetaworlds.com:8002: Think that mock script engine basically only exists for tests [11:52] Andrew Hellershanks: Just under 10 minutes left in the hour. Is there anyone here with some other topic or question(s)? [11:52] MichaelOmega ChristopherGeode: none from me [11:53] Andrew Hellershanks: I see Kayaker typing then Vincent. [11:53] Vincent.Sylvester @hg.zetaworlds.com:8002: Uh oh, we should add a tag for dotnet6 to mantis at some point [11:53] Kayaker Magic: I am looking for suggestions to fix another problem, every time I do a 'generate map' I loose a chunk of memory. [11:53] Andrew Hellershanks: Kayaker, are you using Warp3D? [11:54] Kayaker Magic: Yeah. [11:54] Andrew Hellershanks: That's why. [11:54] Kayaker Magic: Strange thing is, it was not doing it on one server, moved to a new server and this problem started. [11:54] Andrew Hellershanks: AFAIK, it might leak a bit of memory. I thought I had read that was fixed but it might not be depending on which version of code you are building. [11:55] Ubit Umarov: mono/dotnet never releases all memory back [11:55] Andrew Hellershanks: Kayaker, Same version of mono? [11:55] Ubit Umarov: it just leaks things [11:55] Kayaker Magic: I think mono went up a vew decimal points.... [11:55] Vincent.Sylvester @hg.zetaworlds.com:8002: Cached memory is not lost memory, if you see free report less free memory doesn't mean you have less available, it remains cached and recycled when needed [11:55] Andrew Hellershanks: ok. That is not that likely to cause a change in behaviour. [11:56] Vincent.Sylvester @hg.zetaworlds.com:8002: You can force clear the caches, but in rare cases it makes mono unhappy, normally is safe though [11:56] Vincent.Sylvester @hg.zetaworlds.com:8002: Make sure you have the most recent version of libgdiplus [11:56] Andrew Hellershanks: If it just cached memory then running it a second time should not use any more memory. [11:56] Vincent.Sylvester @hg.zetaworlds.com:8002: You can test if that leaks with dynamic textures also [11:57] Kayaker Magic: How do I do that? is there an opensim console command to force a cache clear? [11:57] Vincent.Sylvester @hg.zetaworlds.com:8002: free is a linux command for showing memory distribution, if that shows a lot of memory in cached buffered then you can clear it [11:58] Vincent.Sylvester @hg.zetaworlds.com:8002: Somewhere in sys proc there is a drop_caches, just echo a 1 into that and it will start clearing it up [11:59] Vincent.Sylvester @hg.zetaworlds.com:8002: Course if you have a region going ham on memory you might just pull the rug under it, though that is rare [11:59] Vincent.Sylvester @hg.zetaworlds.com:8002: Normally it will just fetch what memory it needs from the cached pool as well [12:00] Vincent.Sylvester @hg.zetaworlds.com:8002: If you have a leak regarding the texture generation for the maptile itself that will show with dynamic textures as well [12:00] Vincent.Sylvester @hg.zetaworlds.com:8002: I recall an issue with libgdiplus a while back that leaked a lot of memory [12:00] Vincent.Sylvester @hg.zetaworlds.com:8002: Was eventually fixed [12:00] Kayaker Magic: I've got a slideshow that uses cynamic textures, I'll give that a try. [12:01] Kayaker Magic: *dynamic [12:01] Vincent.Sylvester @hg.zetaworlds.com:8002: libgdiplus | 6.0.5 or 6.0.4 should be fixed, anything below that might cause trouble [12:02] Vincent.Sylvester @hg.zetaworlds.com:8002: You can check available versions with apt-cache on debian systems and apt will give you a return on what's installed [12:02] Kayaker Magic: Ubuntu should hve that [12:04] Jamie.Jordan @grid.kitely.com:8002: I think most distros do [12:04] Vincent.Sylvester @hg.zetaworlds.com:8002: Some use yum... *shudder* [12:04] Andrew Hellershanks: :) [12:05] Andrew Hellershanks: I used to use a system that used RPM based package management. [12:05] Kayaker Magic: Just checked libgdiplus, V 6.0.5 [12:06] Andrew Hellershanks: Any other questions, Kayaker? [12:07] Kayaker Magic: No, I'll just keep plugging away at this system... [12:07] MichaelOmega ChristopherGeode: :) [12:08] Vincent.Sylvester @hg.zetaworlds.com:8002: Or throw household objects on IRC until someone helps heh [12:08] Andrew Hellershanks: ok, good luck with it. Next week you can let us know what you learned. [12:08] Andrew Hellershanks: hehe [12:08] Kayaker Magic: I used to run 12 mapgens on 12 regions at once on the old system, on the new hardware the memory dissapers and regions start crashing. [12:08] Andrew Hellershanks: Vincent, Good luck with your test issue. [12:09] Andrew Hellershanks: We are a little past the hour. If there are no other last moment questions or comments I will wrap up the meeting. [12:09] Andrew Hellershanks: Thank you all for coming. See you again next week. [12:10] MichaelOmega ChristopherGeode whispers: sounds good - Have a great week everyone!
