00:36 adfeno       Hi, I can't how to make a require work after minetest.request_insecure_environment() ?
00:36 adfeno       Sorry: meant to ask: “how to”…
00:37 adfeno       lua_api.txt doesn't tell much about how to use that.
00:38 adfeno       I also already set my mod as trusted
00:39 adfeno       but doing a simple “require("some-lua-in-lua-path")” always gives me the same error about mod security.
02:14 MTDiscord    <05e​xe_virus> trusted in minetest.conf?
02:15 MTDiscord    <05e​xe_virus> also, what are you trying to "require"
02:15 MTDiscord    <05e​xe_virus> cause you shouldn't need to use require for getting mod-based stuff
02:15 MTDiscord    <05e​xe_virus> i.e. init.lua in a mod can require adjacent files
02:16 MTDiscord    <05e​xe_virus> if you need stuff from other mods, they should provide that access to you through a global table variable like minetest.functions work
02:51 daiNoZord    Is "home-hosting" a server a bad idea? Any tips?
03:01 MTDiscord    <05e​xe_virus> Haven't tried, people do it all the time
03:01 MTDiscord    <05e​xe_virus> use freedns to manage dynamic IPs
03:02 MTDiscord    <05e​xe_virus> i.e. residential addresses will have their ip address change from time to time
03:02 MTDiscord    <05e​xe_virus> so you register for a subdomain with freedns
03:02 MTDiscord    <05e​xe_virus> and you tell it (via a script) when your IP changes
03:02 MTDiscord    <05e​xe_virus> for example: freeDNS has a minetest.land domain they own
03:03 MTDiscord    <05e​xe_virus> so you would register for a subdomain called <your_server_name>
03:03 MTDiscord    <05e​xe_virus> players would join by typing in: <your_server_name>.minetest.land
03:04 MTDiscord    <05e​xe_virus> That's really the only major* issue with hosting at home
03:04 MTDiscord    <05e​xe_virus> The other problem is residential connections typically have worse upload speeds than VPS services online
03:05 MTDiscord    <05e​xe_virus> I think that's everything I have tips for
03:07 daiNoZord    thanks - is that the same as ddns?
03:15 daiNoZord    ah i think it is - it's a provider. Hey that's great! myserver.minetest.land - works for me :) Yeah I'm on a basic package and the speed isn't great.. VPS is the thing I've been trying to remember for the past couple of days - but I thought home-hosting as a trial if it's safe and then maybe see about hosting elsewhere if there's enough interest for it to be worth the cost
03:17 MTDiscord    <05e​xe_virus> Exactly
03:17 MTDiscord    <05e​xe_virus> I personally use genesisHosting. They have decent linux plans, roughly $3-4 a month
03:18 MTDiscord    <05e​xe_virus> (when you pay 6 months at a time, so like $27 for 6 months or something)
03:18 MTDiscord    <04o​neplustwo> ah yes, 4 * 6 is 27
03:19 daiNoZord    That's good value - what's the speed like there? much lag?
03:26 daiNoZord    $40 a year... about £2.50 pcm.
03:35 MTDiscord    <05e​xe_virus> Collection: taxes are included in that $27 ?  The speed is decent, lag is decent. I consider it a great baseline. I wouldn't host CTF on it or anything though. It flies for normal minetest gameplay with some mobs with maybe max 15 players. It seems to handle 3 factories running at once from techpack decently well. Not great, but playable at that point still.
03:52 daiNoZord    I think I may need to trim down the amount of mods I use. Especially if I add things like realms and arenas
09:50 adfeno       Hi there, is it possible to make bots that would show as players in /status and also on autocompletion, but not having entities nor occupying a server slot ?
10:21 rubenwardy   You can customise server slots
10:21 rubenwardy   User bypass
10:37 adfeno       rubenwardy: thank you, what about making bots/players with no physical entity?
10:37 rubenwardy   Oh right, you mean object
10:37 rubenwardy   Not possible currently
10:37 rubenwardy   Is this a server you run?
10:37 adfeno       Could be.
10:37 rubenwardy   You could make them spectators
10:38 rubenwardy   Or your could make them not players
10:38 adfeno       spectators?
10:38 rubenwardy   Making them not a player won't allow completion thought
10:38 rubenwardy   !mod spectator
10:38 MinetestBot  rubenwardy: Spectator Mode [spectator_mode] by jp - https://forum.minetest.net/viewtopic.php?t=13718 - https://github.com/minetest-mods/spectator_mode
10:40 adfeno       Hm, mod spectator seems to require an existing player to watch.
10:42 rubenwardy   which is what the bot player method would be
10:43 adfeno       So make an entity that is not a player, and then make mod spectator watch that non-player entity ?
10:43 rubenwardy   your two options are:
10:43 rubenwardy   1. Create a bot player using a tool like the one found on the forum. This connects as a player and would allow chat completion
10:43 rubenwardy   2. A Lua mod which pretends to be a player
10:43 rubenwardy   Number 2 is probably better
10:44 rubenwardy   it's better on resources and won't create an object
10:44 rubenwardy   Also, btw - players and entities are the two types of obect. Nonplayer entity doesn't make sense, as all entities are not players
10:44 rubenwardy   This is fairly minetest-specific terminology
10:45 adfeno       rubenwardy: my goal is to make a Minetest to XMPP bridge to send/receive messages at both ends, optionally allowing natively listing room participants in both ends.
10:45 rubenwardy   ahhh
10:45 rubenwardy   Well, you want #2 then
10:45 ShadowBot    https://github.com/minetest/minetest/issues/2 -- Burned wood
10:45 rubenwardy   see the IRC mods
10:46 rubenwardy   you won't be able to use chat completion currently, as there's no API For that yet :tm:
10:49 adfeno       rubenwardy: what if I employ a mod to pretend to be a player but do nothing, then with other mod make the MT+XMPP bridge and make each user from this bridge watch the fake player?
10:49 rubenwardy   you don't need to do that
10:49 adfeno       (watch in the sense of mod spectator)
10:50 rubenwardy   "pretend to be a player" -> you can just simulate chat messages and override /status
10:50 adfeno       What about autocompletion ?
10:51 rubenwardy   you can't do that without connecting to Minetest as an actual player, which would be very expensive
10:51 rubenwardy   or you could modify the C++ cod
10:51 adfeno       Hm, I see… very steep road it seems.
10:51 adfeno       I would also be dealing with IrrLicht along the way too :S
10:53 adfeno       I'll try to follow “override /status” and simulate chat messages then.
10:53 rubenwardy   not related to Irrlicht, as it's server-side only
11:06 adfeno       How to make players solid ?
11:08 rubenwardy   collide_with_objects = true   in object properties
11:09 adfeno       Hm, OK :)
11:12 adfeno       Recently I also tried to use require("lua-script-from-lua-path") in a mod listed on secure.trusted_mods, but Minetest wouldn't let me. I know that from the error message I could set security.enable_security = false, but I wonder: is there any other way?
11:13 rubenwardy   you need to use   ie.require
11:13 rubenwardy   and never ever do  security.enable_security
11:15 adfeno       With security.enable_security = true and security.trusted_mods = mod_name, tried in init.lua: local ie = minetest.request_insecure_environment(); ie.require("lua-from-lua-path") but got same error message about require.
11:15 rubenwardy   this is typically because the mods use require as well, you should do
11:16 rubenwardy   local tmp = require
11:16 rubenwardy   require = ie.require
11:16 rubenwardy   require("lua-form-lua-path")
11:16 rubenwardy   ie.require = require
11:17 adfeno       rubenwardy: shouldn't the last line be “require = tmp” ?
11:18 rubenwardy   ah yeah
11:20 adfeno       Ah, I see, thanks :)

11:39 adfeno       Hm… strange, even with ie.require, some Lua modules can't find some others, even though I have these in LUA_PATH and LUA_CPATH, the same command works in Lua and LuaJIT, and both path variables are the same in Minetest's environment.
11:40 adfeno       I don't know if this matters, but the part which doesn't work seems to use pcall(require, select( something-and-something
11:42 adfeno       I did set the insecure environment's require function as global require before calling the now-modified require.
11:43 adfeno       Ah, I must inspect ie's package paths :)
11:47 adfeno       Well, ie's package.path and package.cpath are all OK as equal to Lua and LuaJIT, so I don't know where it's failing.
11:48 adfeno       ie.package.path ie.package.cpath
11:48 adfeno       s/where/why/
11:57 adfeno       In the same error message there is also another erro for “module "encoding"” which I'm investigating and “encoding” seems to be a file which, as far as I know, should also be found in LUA_PATH.
12:00 rubenwardy   Are you using 5.4.0-dev?
12:03 adfeno       rubenwardy: Minetest 5.3.0
12:03 adfeno       Ah, I see, “module” itself isn't defined in insecure environment.
12:04 adfeno       I'll try replacing it with ie.require and assigning that to a local variable.
12:06 adfeno       Geess  I hate bundling, this XMPP is a must for my group but the most uptodate library seems to be bundling every kind of Lua it depends on, which has lots of old code (including those which use “module”)
12:09 adfeno       If things continue like this I'll ditch this verse library, install libstrophe from Guix (which unbundles everything), and hope to learn how to call that from Lua.
16:28 adfeno       rubenwardy: I think I found the issue, _G doesn't define module, but as far as I can see the insecure environment requested does.
16:47 adfeno       How to allow Lua code loaded from “require” to read /etc/resolv.conf ? I already requested insecure environment and used “require” from ie.
16:48 rubenwardy   You could implement require yourself with a correct fenv
16:48 rubenwardy   fenv is the problem
16:48 rubenwardy   so if you can work out the path to the lua file
16:48 rubenwardy   you can do   loadfile(path)   and then setfenv(func, ie)   on the result
16:48 rubenwardy   then call it
16:48 rubenwardy   require = find the path, run the path, cache the result, return result
16:50 adfeno       Addendum: error message is : “Mod security: Blocked attempted read from /etc/resolv.conf”
16:50 rubenwardy   yeah, that's because you're reading using the sandboxed env
16:54 rubenwardy   made an issue   #10877
16:54 ShadowBot    https://github.com/minetest/minetest/issues/10877 -- Insecure require() should set insecure env on file
16:57 adfeno       rubenwardy: so call it like this? require=ie.require; setfenv(loadfile(path), ie)
16:57 rubenwardy   don't need the require bit
16:58 adfeno       So setfenv(loadfile(path), ie) is enough?
16:58 rubenwardy   setfenv(loadfile(path), ie)()
16:58 rubenwardy   the () calls it
16:58 adfeno       Hm… I see
16:58 rubenwardy   files are functions in Lua
16:59 adfeno       What if the lua module itself uses “require” to load other modules ?
17:00 rubenwardy   setfenv handles that
17:00 rubenwardy   setfenv means that the file will use globals from ie
17:00 rubenwardy   including the require
17:00 adfeno       Hm… I see.
17:00 adfeno       Thanks :)
17:07 adfeno       rubenwardy: in loadfile(path) you mean the script that is attempting to both call others with require and also trying to read /etc/resolv.conf, right ?
17:08 rubenwardy   yeah
17:08 rubenwardy   I mean the remove script as well
17:08 rubenwardy   remote
17:08 rubenwardy   like library script
17:08 rubenwardy   if you're just trying to read resolv from a mod, you can do    ie.io.open
17:11 adfeno       I tried this: local testing = setfenv(loadfile("/usr/local/share/lua/5.1/verse/init.lua"), ie)();        … but now it errors with: Mod security: Blocked attempt to read from "/usr/local/share/lua/5.1/verse/init.lua".
17:11 rubenwardy   sorry,  ie.loadfile
17:14 MTDiscord    <03Z​ander_200> hi im in the IRC now
17:15 MTDiscord    <04o​neplustwo> oh dear
17:16 MTDiscord    <03Z​ander_200> what
17:34 adfeno       rubenwardy: strangely enough, doing        local verse_file = setfenv(loadfile(verse_init_file_path), ie); local verse = verse_file().init("client")      works fine, but most of the auxiliary functions seem to be nil
17:35 adfeno       s/most of the auxiliary functions/most of the *verse* auxiliary functions/
17:40 adfeno       Hm, I think I have an idea
17:50 adfeno       Hm… no luck
18:19 adfeno       OK, I decided to abandon the XMPP bridge, no XMPP Lua library is maintainable in a system without bundling, and even so, all the ones I tried fail because them themselves forget to include stuff.
