re animateJoints: I vaguely remember this being discussed some time, but I forgot whether someone actually tested it and found it was broken or that was just a theory |

<localhost> also in my settings set synchronous = 0, but in the dump database the pragma doesn't exists |
| 09:39 |
[MTMatrix] |
<localhost> I just reacreated database manually with some pragmas, nice workaround |

<grorp> Merging #13779 in 10 min |
| 13:18 |
ShadowBot |
https://github.com/minetest/minetest/issues/13779 -- Fix that negative integer values for float settings don't get a ".0" suffix by grorp |
| 13:40 |
MTDiscord |
<grorp> Done. |
| 13:50 |
erle |
question to devs: has the 10 min thing ever resulted in something being not merged? it seems awfully low (i mean what if someone is not glued to their screen at all times) |
| 13:50 |
erle |
or am i misunderstanding its purpose? |

cdb downloads really need any kind of progress indication, even if it's just some stuff printed to console |
| 16:21 |
sfan5 |
I just waited 3-4 minutes for some unknown amount of data to be downloaded, unpacked size is 160 MB at least. My internet could manage more than 10 times that in the same time at least. |

<rollerozxa> uh yeah, downloading from CDB seems to be kinda slow |

consider doing some bandwidth limiting (QoS) for downloads if you don't already |

nginx config: https://gist.github.com/rubenwardy/05b9eb2ed4990ff8d955b2bd2ff26fd3 |
| 16:38 |
rubenwardy |
so do I want limit_rate ? |
| 16:38 |
sfan5 |
as an addition to limit_req, maybe |
| 16:39 |
sfan5 |
import question first is: where's the current bottleneck? disk, network or cpu? |
| 16:39 |

you can enable "detailed cpu time" to easily see when processes are spending time waiting for io (in gray here): https://0x0.st/HpRv.jpg |
| 16:48 |
sfan5 |
judging by what you showed it's probably an io bottleneck |

a lot of the top users in ifconf are aws and linode instances |

PMed an image with more info from iftop, the top users are on aws and linode so maybe abusing it or scraping? |
| 17:19 |
rubenwardy |
ok turns out it wasn't sorted, probably just crawlers |

<localhost> How specify two or more bind interfaces? enp1,enp2 is valid or no supported multibinding? |
| 18:02 |
sfan5 |
not supported |
| 18:05 |
[MTMatrix] |
<localhost> eh |
| 18:08 |
sfan5 |
no idea who wrote that description anyway, bind_address does not specify an interface |
| 18:08 |
sfan5 |
it specifies an IP |
| 18:10 |
[MTMatrix] |
<localhost> hm but tun0 works fine, but one problem, httpapi also binds on this interface and it can't fetch some content from lo interface π |
| 18:11 |
sfan5 |
it works for curl but not MT's networking code |

i have a suggestion to speed up CDB if it is upstream-bandwith-limited: grab some torrent library and use cdb as a webseed. |

no |

ok |

<grorp> sfan5: #13550 has two approvals now. You self-requested a review on that PR. Do you still want to review it or can it be merged? |

https://github.com/minetest/minetest/issues/13550 -- Improve UX when no game exists and drop `default_game` by rollerozxa |
| 20:06 |
[MTMatrix] |
<localhost> minetest can handle more than 1000 players? |
| 20:08 |
erle |
localhost i'll doubt any amount of 200 it until someone shows a server like that. |
| 20:08 |
erle |
over 200 i mean |
| 20:08 |
erle |
you have one? |
| 20:09 |
erle |
and even if the engine can handle that (which i do not know), i have enough experience with badly written mods that send random crap to everyone scaling with the amount of players |
| 20:10 |
erle |
or have some globalstep that does player stuff |
| 20:10 |
erle |
localhost so, show and tell? |
| 20:11 |
[MTMatrix] |
<localhost> server have super simple 1 block (singlenode) world, it can help improve expirence? :D |
| 20:11 |
erle |
i don't think it's really about the world in any case |
| 20:12 |
erle |
i mean, you can make a world that is laggy for 5 players pretty easily: fill chests with recursive shulkers or so |
| 20:13 |
erle |
localhost, if this is a practical question, i am interested. if it is a theoretical, i am not. are you running a server and try to up the user count? |
| 20:13 |
ROllerozxa |
I don't think even voxelmanip classic would be able to handle 1000 players even if it was hosted on a beefy dedi server |
| 20:14 |
erle |
the only tried-and-tested way i know to make a server handle more players bandwith-wise is to shave bytes off here and there (often many times, with each single attempt looking like it would not improve much) |
| 20:14 |
[MTMatrix] |
<localhost> also, voxelmanipulator via lua scripts have native speed as native writen mapgen? |
| 20:15 |
erle |
computation-wise, it's about not being stupid |
| 20:15 |
erle |
like not accidentally quadratic or so |
| 20:16 |
erle |
luk3yx you made this python library for minetest clients, right? did you run any load tests with it? |
| 20:17 |
[MTMatrix] |
<localhost> wut!? python library for minetest, whoa |
| 20:19 |
[MTMatrix] |
<localhost> In this case, minetest more CPU or RAM like? |
| 20:21 |
erle |
what do you mean |
| 20:21 |
erle |
minetest can fill your RAM, regardless of how much you have, if you do something stupid with it |
| 20:22 |
[MTMatrix] |
<localhost> of cource, i think, minetest eat less resources than minecraft java stuff |
| 20:22 |
erle |
an example: cora had an implementation of fire spread that worked eXaCtLy LiKe MiNeCrAfT. if you ask the engine to run a counter per node for the age of the fire and the fire node copies itself, filling the world with more counters β¦ eventually you run out of RAM, regardless of how much you have. |
| 20:23 |
erle |
cora fixed it by making the fire die probabilistically |
| 20:23 |
erle |
like, each tick the fire had a chance to die β this does not require a counter (and thus a bit of RAM) for every fire node |
| 20:24 |
erle |
if you have a minetest engine game you *probably* want to find all these little stupid things before even thinking about the engine stuff |
| 20:31 |
[MTMatrix] |
<localhost> or cource, stupid things like create tnt world Β is huge pain.... |
| 20:33 |
luk3yx |
erle: I don't think I wrote a client library? I made something once to try and detect servers lying about players on the server list but it was very simple (no reliable packet handling) and only tries to log in rather than joining |
| 20:34 |
luk3yx |
I'm sure someone made a Go library at some point |
| 20:34 |
luk3yx |
https://github.com/minetest-go/minetest_client |
| 20:34 |
erle |
luk3yx then i confused you with someone |
| 20:35 |
erle |
the go library is from anon5 i think? |
| 20:36 |
luk3yx |
I think BuckarooBanzai wrote the one I linked |
| 20:38 |
[MTMatrix] |
<localhost> oh it mean bot client for minetest already exists? π Β >_< |
| 20:38 |
[MTMatrix] |
<localhost> bots everywhere |
| 20:38 |
[MTMatrix] |
<localhost> eh |
| 20:41 |
erle |
localhost how about you use that and test and then report your findings |
| 20:42 |
[MTMatrix] |
<localhost> but still thanks! |
| 20:43 |
[MTMatrix] |
<localhost> and this is true, mine **test** |
