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. |

<exe_virus> trusted in minetest.conf? |
| 02:15 |
MTDiscord |
<exe_virus> also, what are you trying to "require" |
| 02:15 |
MTDiscord |
<exe_virus> cause you shouldn't need to use require for getting mod-based stuff |
| 02:15 |
MTDiscord |
<exe_virus> i.e. init.lua in a mod can require adjacent files |
| 02:16 |
MTDiscord |
<exe_virus> if you need stuff from other mods, they should provide that access to you through a global table variable like minetest.functions work |

Is "home-hosting" a server a bad idea? Any tips? |
| 03:01 |
MTDiscord |
<exe_virus> Haven't tried, people do it all the time |
| 03:01 |
MTDiscord |
<exe_virus> use freedns to manage dynamic IPs |
| 03:02 |
MTDiscord |
<exe_virus> i.e. residential addresses will have their ip address change from time to time |
| 03:02 |
MTDiscord |
<exe_virus> so you register for a subdomain with freedns |
| 03:02 |
MTDiscord |
<exe_virus> and you tell it (via a script) when your IP changes |
| 03:02 |
MTDiscord |
<exe_virus> for example: freeDNS has a minetest.land domain they own |
| 03:03 |
MTDiscord |
<exe_virus> so you would register for a subdomain called <your_server_name> |
| 03:03 |
MTDiscord |
<exe_virus> players would join by typing in: <your_server_name>.minetest.land |
| 03:04 |
MTDiscord |
<exe_virus> That's really the only major* issue with hosting at home |
| 03:04 |
MTDiscord |
<exe_virus> The other problem is residential connections typically have worse upload speeds than VPS services online |
| 03:05 |
MTDiscord |
<exe_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 |
<exe_virus> Exactly |
| 03:17 |
MTDiscord |
<exe_virus> I personally use genesisHosting. They have decent linux plans, roughly $3-4 a month |
| 03:18 |
MTDiscord |
<exe_virus> (when you pay 6 months at a time, so like $27 for 6 months or something) |
| 03:18 |
MTDiscord |
<oneplustwo> 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 |
<exe_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 |

I think I may need to trim down the amount of mods I use. Especially if I add things like realms and arenas |

Could be. |

You could make them spectators |

Or your could make them not players |
| 10:38 |

Making them not a player won't allow completion thought |

| 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 |

ahhh |

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 |

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 |

ie.require = require |

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. |

I'll try replacing it with ie.require and assigning that to a local variable. |

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”) |

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 |

https://github.com/minetest/minetest/issues/10877 -- Insecure require() should set insecure env on file |
| 16:57 |

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 |

Hm… I see. |
