01:15 GreenDimond Negative
01:16 GreenDimond No idea when est31 will get around to it
01:17 Emerald2 Am I gonna have to remove the dev version to avoid package conflicts again?

15:34 JDCodeIt joined #minetest
15:36 JDCodeIt 5.0.0 releases today - any available benchmarks on the server versus 0.4.17.1? Can the same hardware support more players now?
15:36 rubenwardy there have been quite a lot of optimisations
15:36 rubenwardy but also a lot of new features
15:36 rubenwardy it would be good to see benchmarks made
15:37 JDCodeIt Were any more parts of the code made multi-threaded or is it mostly still just emerging new blocks?
15:38 rubenwardy no, just emerging
15:38 rubenwardy there's been optimisations to ABMs though
15:39 JDCodeIt Is there a thread for the ABM improvements?
15:40 JDCodeIt ...a series of fruitful discussions, not a lightweight process :-)
15:40 rubenwardy https://github.com/minetest/minetest/pull/7555
15:40 rubenwardy tl;dr: whether an ABM should check a MapBlock (16x16x16 nodes) is now cached
15:40 JDCodeIt left #minetest
15:41 rubenwardy lol
15:41 JDCodeIt joined #minetest
15:50 JDCodeIt I left to read 7555 - good discussion . I'm going to test it on some copies of worlds and try to measure CPU difference.

17:43 JDCodeIt Any migration path things to consider if we want to use an existing 0.4.17.1 world with MT 5.0.0 server? Or is that a no-go?
17:51 jas_ https://i.giphy.com/media/3D46bhclQgY7ZlIcOJ/source.mp4
17:51 jas_ i think it's okay, JDCodeIt
17:52 jas_ only thing that broke was network compatibility with the new version, if i'm not mistaken.  so if you upgrade to the server, the clients have to as well.
17:52 jas_ "broke."  probably a poor choice of wording.

18:20 JDCodeIt Hmmm well, my first attempt failed - MT 5.0.0 server on 32-bit linux, client 64-bit linux compiled from stable-5 branch, and using minetest_game from stable-5 - serialization error connecting to the world made with 0.4.17.1 mgv6.
18:20 sfan5 and that error is?
18:21 JDCodeIt let me repeat and get the exact error
18:22 JDCodeIt Malformatted inventory list, list=main, read 624 of 2648 ItemStacks.
18:23 sfan5 more context#
18:23 scr267 joined #minetest
18:23 sofar that's a lot of itemstacks
18:24 JDCodeIt This is in the client - immediately following initializing nodes: An error occurred: A serialization error occurred: <insert above> The server is probably running a different version of Minetest
18:24 sfan5 so a client-side error
18:25 JDCodeIt Client title is Minetest 5.0.0 [Main Menu] - it was compiled today from stable-5
18:28 JDCodeIt The player file main has "List main 32"
18:28 sfan5 !c 2648 / 8

18:30 sfan5 zsh: segmentation fault (core dumped)  ./minetest
18:30 sfan5 ....
18:30 JDCodeIt I think I know what it is - default item stack size was changed - let me try updating
18:31 JDCodeIt It's trying to squish some larger stacks into the default 99 max, right?
18:31 sfan5 i don't think so
18:36 JDCodeIt unified_inventory trying to build the list?
18:37 jas_ (random guess: player backend?)
18:37 JDCodeIt files
18:44 JDCodeIt An new player is able to join. Seems something with existing players
18:45 ensonic joined #minetest
18:55 JDCodeIt narrowing - happens with a new player if they have all privs when connecting
18:56 sfan5 sounds like a broken mod
19:00 nowhereman joined #minetest
19:08 DrFrankenstone joined #minetest
19:09 JDCodeIt priv = creative fails - suspect this is something to do with unified_inventory
19:17 kaeza joined #minetest
19:19 Soni left #minetest
19:20 p_gimeno the message still comes from the core, and it's a serialization error
19:20 p_gimeno I don't think a mod can cause that?

19:29 sfan5 not directly, of course

20:07 JDCodeIt hard to locate the serialization error without stack trace. What is the best way to find out what caused it?
20:10 sfan5 gdb might(?) be able to catch it directly when it happens

21:07 p_gimeno maybe try dumping the mapblock with sfan5's dump utility?
21:08 sfan5 this sounds like it'd be in a player inventory
21:09 p_gimeno this is the fragment throwing the exception: https://github.com/minetest/minetest/blob/master/src/inventory.cpp#L476
21:10 p_gimeno to me it looks like either corruption, or an engine bug, or both

21:25 argyle77 Is there any way to tint a user's view other than associated with a particular node?
21:33 kaeza argyle77: You could use a full screen semi transparent image
21:34 kaeza On the HUD I mean.
21:52 scr267 joined #minetest
22:20 argyle77 Thanks kaeza, I will look into it.

22:51 sfan5 this sounds a lot like your problem
22:52 JDCodeIt having a look
22:55 JDCodeIt Yep same error - creative priv was triggering this

23:18 Sveta Emerald2: perhaps if there is no luck resolving the internationalisation issue on irc, there is an email address to query instead?
23:19 argyle77 works perfect, kaeza!
23:19 rodskagg is there a convention for north, south, east west in minetest? like +x is north?
23:20 Emerald2 Sveta sorry I don't know.
23:20 argyle77 +z i think
23:20 rodskagg argyle77: thanks
23:21 argyle77 push f5.
23:21 argyle77 it gives positions and directions
23:21 rodskagg :o
23:21 rodskagg whoah.
23:21 rodskagg so cool.
23:21 rodskagg thanks argyle77. :D
