00:20 lhofhansl Thanks! It's safe to merge. If you prefer I'll trainee the FOV default change, it's not needed, just a cosmetic cleanup
00:20 lhofhansl I'll remove...
00:27 paramat no need
00:28 paramat 0 is cleaner than that equation
00:28 garywhite What's luarocks?

01:21 garywhite Will someone please approve #4472 before Wednesday? It'd be one thing that MT would have a major advantage over MC

14:35 PR4061works Kulgan`: VanessaE found mem usage was growing due to logs, not about water queue
14:36 VanessaE well no
14:36 VanessaE the logs were a problem, fixed, but there is still an apparent memory leak
14:36 VanessaE whether it's the liquid queue, idk.
14:36 PR4061works nice
14:37 PR4061works missed that part
14:38 VanessaE that's because I hadn't yet said it :)
14:38 VanessaE there's not really enough new stats since I factored-out the logs to make a fair judgment
14:39 VanessaE https://daconcepts.com/vanessa/h​obbies/minetest/stats-daily.html  but if you look at the memory graph here, you can see a ~1 GB drop in usage when the servers were restarted at 0700.
14:40 PR4061works VanessaE: try slowing liquids to a crawl? or applying 4061?

15:53 PR4061works juhdanad: what do you think about moving fog farther a little? This get me thinking about it:https://imgur.com/a/AKbkr (shaders enabled)
15:56 PR4061works juhdanad: right now I feel like some stuff is completely hidden by fog, but rendered (like on pics above)
15:56 juhdanad You can set the fog for yourself as you want.
15:57 PR4061works juhdanad: really?
15:57 PR4061works can't find it in config
15:59 proller joined #minetest-dev
16:00 juhdanad Advanced settings->Client->Graphics-​>In-Game->Advanced->Viewing range
16:01 PR4061works juhdanad: i use 240, what i mean is fog compleately hides some chunks on that screenshot
16:01 juhdanad But I do think that it should be easier to find.
16:02 PR4061works maybe it needs to at least slightly uncover that parts
16:02 juhdanad On the first picture you disabled fog, am I right?
16:02 PR4061works right
16:02 PR4061works look center and left trees on far side
16:02 PR4061works compare two screens
16:03 juhdanad In this mode your client draws everything.
16:03 PR4061works make them in two tabs
16:03 PR4061works hmmm, but i looked into F6 menu and drawing not changed
16:03 juhdanad Try it out! Fly ~1000 nodes, look back, and disable fog.
16:03 juhdanad You should see everything that has been ever drawn.
16:04 PR4061works block drawn is the same when i turn off the fog
16:04 PR4061works nope
16:04 juhdanad (at least full viewing range with the R key does this)
16:04 PR4061works or wait
16:05 PR4061works i don't use R right now
16:05 juhdanad Sorry, then I misunderstood you.
16:05 PR4061works it draws everything if only R is used
16:06 PR4061works i'm really sure fog hides completely some parts, will post new screens
16:06 VanessaE something I especially like is that F5 now turns on wireframe mode if you press it enough times
16:08 PR4061works juhdanad: https://i.imgur.com/cdGF0Qd.png vs https://i.imgur.com/fQ9CqZY.png
16:09 PR4061works so that part can be uncovered a bit for sure
16:10 longerstaff13 joined #minetest-dev
16:10 PR4061works juhdanad: i have impression it is in some parts only
16:11 juhdanad Oh, somebody made a commit that made fog round. However the server sends blocks in a cubic shape. You are seeing towards the edge.
16:12 PR4061works juhdanad: you sure? blocks are send in round shape now
16:13 juhdanad TWell, I don't know what the latest version does. Fly up, and with full view range look down. So you can see the shape of sent blocks.
16:15 PR4061works juhdanad: https://github.com/minetest/minetest/commi​t/e7c62edec90c476b54ea7cf7c44354f1609e4575
16:16 PR4061works juhdanad: lol, i think I bothering wrong person
16:16 PR4061works lhofhansl did fog changes...
16:16 PR4061works not you
16:16 PR4061works sorry
16:16 juhdanad No problem.
16:20 PR4061works juhdanad: i wonder if thats you who tried to fix ghost lighting?
16:20 juhdanad Yes, I am. And at this moment I'm working on it.
16:21 juhdanad At the current state I think it works, but uses too much CPU.
16:21 PR4061works juhdanad: good luck with that
16:21 juhdanad So I'm trying to make it faster.
16:22 juhdanad Thanks!
16:27 PR4061works damn, I also has this impression of bright grass as someone noted
16:43 YuGiOhJCJ joined #minetest-dev
16:43 PR4061works wonder if someone will reconsider improving of algorithm that is used for background darkening, due to problems with it in some parts of floatlands: https://github.com/minetest/minetest/issues/3577
16:47 juhdanad How can I add six new bits to mapblock data? Should I create a new version number?
16:49 sfan5 why 6 bits
16:49 juhdanad Each bit indicates that the light spreading could not be finished in that direction because the neighbor block was not loaded.
16:50 juhdanad This prevents light calculating when all light spreading is complete.
16:51 PR4061works interesting
16:51 PR4061works wonder if this can be related to liquid spreading that hmmmm was thinking
16:52 juhdanad I don't know - I haven't seen hmmmm's algorithm.
16:54 PR4061works he was thinking about: how in some way mark the water when it settle to not process it next time
16:54 PR4061works nevermind

17:34 i joined #minetest-dev
17:35 est31 is it for network serialisation, or for disk serialisation?
17:36 juhdanad For both.
17:36 est31 ok

17:37 est31 from what you told the change sounds reasonable
17:42 PR4061works ugh, can't put stick, wooden stairs into furnace
17:47 Krock you can craft sticks into planks, depends on subgame and mods
17:50 PR4061works nevermind, sfans mtg is probably too old, it was fixed recently i guess
17:51 PR4061works hold on, can't use furnace in creative
17:52 Krock lolwhat?
17:52 PR4061works lolyes
17:52 PR4061works or not
17:53 Krock maybe you're doing it wrong. works fine here

21:27 paramat joined #minetest-dev
21:28 paramat green was used to blend with the papyrus colour
21:28 paramat it's not ideal, perhaps it could be dirt now since grass only spreads from neighbours
21:29 paramat hm good idea
21:29 juhdanad Yes, I think dirt would be better.
21:29 paramat i avoided dirt before because it would just change to grass
21:29 paramat will do this
21:30 paramat Fixer your input is so useful
21:30 juhdanad By the way, what does !tell do?
21:30 garywhite !tell juhdanad this

21:30 ShadowBot garywhite: O.K.
21:30 paramat or ~tell
21:31 juhdanad Oh, I thought it sends an e-mail or something.
21:31 paramat the message pops up for the recipient when they next log in

21:45 paramat #4829
21:45 ShadowBot https://github.com/minetest/minetest/issues/4829 -- Mapgen: Make mgv7 the default mapgen by paramat
22:05 VanessaE 2016-12-03 23:03:13: WARNING[Server]: ServerEnv: Trying to store id = 49415 statically but block (-20,12,44) already contains 10002 objects. Forcing delete.
22:05 VanessaE this really, REALLY needs fixed....
22:05 VanessaE (especially since the per-block limit is 500)
22:05 PR4061works lol, wonder what are those objects
22:05 sfan5 why do you blocks have 10k objects ಠ_ಠ
22:05 VanessaE I have no idea at all
22:05 sfan5 your*
22:05 PR4061works is it possible to print list of them?
22:05 VanessaE why is the engine allowing the count to exceed 500?
22:06 sfan5 nobody implemented the check in that place
22:06 sfan5 or rather it's hard to keep track of which entities move to which mapblock
22:11 VanessaE that mapblock is up in the air, far from any land.  only one tall building near that spot, and all it has for entities is a bunch of signs.
22:11 VanessaE /clearobjects quick   helps though.
22:16 VanessaE ...and it would seem that the old "flat player skin" bug has resurfaced.
22:16 red-001 why does minetest even keep that texture around?
22:17 VanessaE I don't mean the "green guy"
22:17 VanessaE I mean a regular "sam"/minecraft-type skin being laid out flat-sprite style
22:19 red-001 so even worse then the green sprite?
22:19 VanessaE yeah
22:19 VanessaE imagine taking a regular skin file and just...displaying it raw.
22:19 VanessaE not wrapping it around a model
22:19 red-001 thats pretty bad
22:20 VanessaE it's an olllllllllld bug
22:20 red-001 is it a bug in the lua code?
22:20 red-001 or the c++ code?
22:20 VanessaE no idea
22:21 red-001 any sure way to reproduce it?
22:21 red-001 or does it happen at random?
22:21 VanessaE the only thing I can be sure of is that entity glitch ^^^ can help cause it
22:22 VanessaE because it still, to this day, deletes player refs/handles too
22:31 PR4061works VanessaE: cheapie created very dirty hack to avoid this
22:31 PR4061works VanessaE: i sometimes get kicked too on login to some of your servers
22:31 PR4061works because of this id = crap
22:31 VanessaE I saw his hack
22:32 VanessaE figured I'd wait for the devs to decide what to do about it
22:32 PR4061works why not somehow get list of those objects, what are they, and somehow deduce why they are there
22:33 VanessaE didn't seem like there was any point, the only thing in the are that even creates entities is signs and LCD screens, and they update very infrequently
22:36 Shara Regarding the "flat skin" bug. I've noticed it's likely to happen the same time as the "multiple players named unknown in the player list" bug.
22:38 Shara Players time out, and seem to get replaced on the player list by "unknown", and when they sign back in, they have flat skins.
22:38 PR4061works o.O
22:38 Shara It's extremly rare, but have noticed they seem to go together.
22:38 VanessaE that's what happened to me.
22:39 VanessaE I signed in, got caught-up and deleted with those ^^^ entities, had to quit and sign on again, and got the flat skin.
22:39 Shara I've previously entered /status on my server to get "unknown, unknown, unknown, unknown, Shara" for example, when it's just me there and others timed out
22:40 Shara Haven't seen it in quite a long time now.

23:08 milllersman anybody remembering my mapgen with strictly downhill flowing rivers? I'm thinking of redoing the implementation in a more generic way
23:09 milllersman my idea is to create an abstract base class that provides the tools for writing recursively refining MapGens
23:09 paramat i certainly remember it, and tried it
23:10 milllersman in theory it might even be possible to make them scriptable
23:12 milllersman joined #minetest-dev
23:12 milllersman the worlds the old one generated are ugly as the ridges of mountains were always on a grid with a power of two step-size, small ones at around 4x4 while bigger ones had a 64x64 grid or even bigger...

23:15 millersman joined #minetest-dev
23:16 millersman joined #minetest-dev
23:16 millersman in theory recursive refinement allows to have non-local rules (like water always goes in the direction of decreasing y regardless of how long rivers are) with comparable speed to noise-based generators
23:17 millersman sorry for spaming with reconnects :(
23:18 millersman is there any interest in integrating such a feature in the official minetest?
23:21 paramat yes i'm interested
23:21 millersman joined #minetest-dev
23:22 paramat it can certainly be considered
23:25 millersman how could i best communicate the general concept and my ideas for the implementation details?
23:25 paramat an issue at github
23:27 millersman ok, but there are a lot of details, hope i'm able to write it in a clear way
23:28 paramat well hmmmmm at least will probably understand it
23:30 millersman ok, so i'll try it
23:30 millersman joined #minetest-dev
