02:28 erle        here is my minetest-servers tool https://forum.minetest.net/viewtopic.php?f=14&t=27984&p=409054

10:36 erle        impostoria
10:36 hacknorris  lmao
10:37 ROllerozxa  ah I get it now lmao
10:37 hacknorris  ye xd
13:46 hacknorris  anyways - someone already made parkour other than "inside the box" and isnt me? just asking...
14:01 hacknorris  dead chat
14:19 erle        hacknorris yes
14:19 erle        go to minigame server
14:19 erle        there is a parkour section
14:38 hacknorris  ?
14:38 hacknorris  ah minigame. probly smol. there are no big ones?
14:57 hacknorris  dead chat
14:59 jason101    i'm fascinated how i rename the wor
15:01 hacknorris  ?
15:19 hn          so is there any bigger parkuor server in minetest except of "inside the box" ?
16:06 Wuzzy       I am slightly confused by the register_decoration noise handling
16:07 Wuzzy       so the docs say that decorations are placed per "square division" but what does that mean exactly?
16:07 Wuzzy       and at which point are decorations placed, anyway? whenever the Perlin noise value >= 0?
16:07 hacknorris  x^2/y ? or smth... maths
16:07 hacknorris  idk
16:08 hacknorris  ah, decorations?
16:08 hacknorris  that their on one square at surface and making X on it probly...
16:08 hacknorris  or smth
16:36 MTDiscord   <AFCM> excuse me but which it the AuthMechanism used with modern servers?
16:38 MTDiscord   <SX> SRP?
16:38 erle        SRP, why?
16:38 erle        AFCM are you making a non-minetest client?
16:39 MTDiscord   <AFCM> I mean
16:39 MTDiscord   <AFCM> switch (chosen_auth_mechanism) {         case AUTH_MECHANISM_FIRST_SRP: {             // send srp verifier to server             std::string verifier;             std::string salt;             generate_srp_verifier_and_salt(getPlayerName(), m_password,                 &verifier, &salt);              NetworkPacket resp_pkt(TOSERVER_FIRST_SRP, 0);             resp_pkt << salt << verifier << (u8)((m_password.empty()) ? 1 : 0);
16:39 MTDiscord   Send(&resp_pkt);             break;         }         case AUTH_MECHANISM_SRP:         case AUTH_MECHANISM_LEGACY_PASSWORD: {             u8 based_on = 1;              if (chosen_auth_mechanism == AUTH_MECHANISM_LEGACY_PASSWORD) {                 m_password = translate_password(getPlayerName(), m_password);                 based_on = 0;             }              std::string playername_u = lowercase(getPlayerName());             m_auth_data =
16:39 MTDiscord   srp_user_new(SRP_SHA256, SRP_NG_2048,                 getPlayerName().c_str(), playername_u.c_str(),                 (const unsigned char *) m_password.c_str(),                 m_password.length(), NULL, NULL);             char *bytes_A = 0;             size_t len_A = 0;             SRP_Result res = srp_user_start_authentication(                 (struct SRPUser *) m_auth_data, NULL, NULL, 0,                 (unsigned char **) &bytes_A, &len_A);
16:39 MTDiscord   FATAL_ERROR_IF(res != SRP_OK, "Creating local SRP user failed.");              NetworkPacket resp_pkt(TOSERVER_SRP_BYTES_A, 0);             resp_pkt << std::string(bytes_A, len_A) << based_on;             Send(&resp_pkt);             break;         }         case AUTH_MECHANISM_NONE:             break; // not handled in this method     }
16:39 erle        stop doing this
16:40 MTDiscord   <AFCM> ?
16:40 erle        pasting lines of code
16:40 erle        use a pastebin like https://mister-muffin.de/paste
16:40 MTDiscord   <SX> Code blocks does not look good on IRC side...
16:40 MTDiscord   <AFCM> ok
16:41 erle        if the user does not exist, you get AUTH_MECHANISM_FIRST_SRP, otherwise AUTH_MECHANISM_SRP, correct?
16:42 MTDiscord   <AFCM> but why is AUTH_MECHANISM_SRP just after AUTH_MECHANISM_LEGACY_PASSWORD
16:43 MTDiscord   <AFCM> Are AUTH_MECHANISM_SRP and AUTH_MECHANISM_LEGACY_PASSWORD handled the same?
16:43 MTDiscord   <AFCM> (I don't know much about cpp)
16:43 erle        AFCM try examining the packets on the wire using the wireshark dissector
16:43 erle        you will see how the SRP works
16:44 erle        again, what are you trying to do?
16:44 MTDiscord   <SX> I've not looked at that bu I would guess if client used legacy password auth then server accepts that
16:44 MTDiscord   <AFCM> web authentification service
16:45 MTDiscord   <SX> Just auth directly against DB, if you want SRP for web pages then browser javascript implementation for SRP is needed...
16:45 erle        AFCM explain?
16:45 erle        i don't get it, you want a web service to log in?
16:46 erle        or to register?
16:46 MTDiscord   <SX> Otherwise you'll be doing "crippled SRP" like what I suppose "legacy password auth" is doing in engine code
16:46 MTDiscord   <SX> (password sent to server and server does "SRP", not real SRP anymore but same thing basically)
16:48 MTDiscord   <AFCM> you have a website allowing users to create an account then they can connect to minetest servers with their credentials and the minetest server will verify them using the web API
16:48 MTDiscord   <SX> I mean functions same but loses security features, client password is exposed
16:49 MTDiscord   <SX> You want your own auth backend service which directly authenticates user without minetest engine...
16:49 MTDiscord   <SX> I guess there's at least few ready made pieces around git... somewhere...
16:51 lsab        hello. I'm using i3 inventory, as I'm adm with creative privs I can't see recipes, is there some way to see that?
16:53 MTDiscord   <AFCM> I would use both bcrypt (for the website/API) and SRP (for the API endpoint allowing minetest to compare it with the encrypted password given by clients)
16:55 MTDiscord   <SX> Why you would use both if you're planning to use SRP anyway?
16:56 erle        split-brain account db?
16:56 MTDiscord   <SX> (any hash based auth takes away benefits of SRP)
16:58 MTDiscord   <SX> Well there's Buckaroo's https://hub.docker.com/r/minetestauth/minetest-auth-proxy / https://github.com/minetest-auth-proxy which does password auth using engine (through mod)
17:01 MTDiscord   <SX> But if building custom solution from scratch I would recommend going through direct db connection instead of using mod as a proxy, mod makes things a lot easier / faster to get working though.
17:01 MTDiscord   <SX> (easier because you can completely skip actual authentication implementation)
17:10 erle        AFCM did you see this? might be of interest https://forum.minetest.net/viewtopic.php?f=14&p=409075#p409075
17:14 MTDiscord   <AFCM> I basically want to encode a string the same way its encoded then its passed to the minetest auth API https://github.com/minetest/minetest/blob/2d8eac4e0a609acf7a26e59141e6c684fdb546d0/doc/lua_api.txt#L8937
17:26 chaverinho  .
18:26 MTDiscord   <SX> You can't. Well, you can but it is auth implementation detail that depends on other things. Basically here's "default" encoding: https://github.com/minetest/minetest/blob/2d8eac4e0a609acf7a26e59141e6c684fdb546d0/src/util/auth.cpp#L29-L47
18:33 sfan5       you can take a plain text password, generate the SRP data and use this to reset an users password inside MT
18:33 MTDiscord   <SX> What password actually is depends on how it was created / updated, that's SRP detail. It is either SRP derived key (should be this in most cases) or actual password hash (for legacy)
18:34 sfan5       also the code you linked is the legacy password
18:37 sfan5       <AFCM> you have a website allowing users to create an account then they can connect to minetest servers with their credentials and the minetest server will verify them using the web API
18:37 sfan5       ^ if you want to do this I suggest writing directly to the database
19:04 MTDiscord   <AFCM> what does "write to the database" exactly mean?
19:08 sfan5       open auth.sqlite and write to the `auth` table, changing the `password` column
19:08 MTDiscord   <SX> Basically what said earlier: if building custom solution from scratch I would recommend going through direct db connection instead of using mod as a proxy That is, you connect to minetest user/auth db and do whatever is needed like authenticate user or create users
19:10 MTDiscord   <AFCM> but isn't sqlite only allowing a single client at a time?
19:12 sfan5       only one client can write at a time
19:12 MTDiscord   <SX> btw will engine lock it, no?
19:13 sfan5       sqlite will lock the file during writes
19:16 MTDiscord   <SX> well, some things take exclusive lock for software lifetime and prevents anyone else doing anything but that's legacy thing. Just I would not be surprised if there's some legacy involved :p
19:26 erle        sqlite is one writer many readers
19:26 MTDiscord   <SX> Ofc  sqlite locking is not really that fool proof (because that's not possible with way how sqlite works) so better to have  backups anyway
19:28 erle        last time a looked into sqlite code i was irritated to no end though
19:28 MTDiscord   <SX> (it could be better to go with postgres anyway for multiple concurrent db clients)
19:29 erle        [insert a rant about sqlite 1 based array indexing and UB here]
19:30 erle        does sqlite still try to use relational operators to compare pointers? :D
20:27 fluxionary  is there any weird logic for connected textures? trying to register some walls via `walls:register` in minetest_game, and get them to connect to the "regular" version of the node. e.g. a wall version of "default:brick". even after adding "default:brick" to the wall's connects_to list, and adding the "wall" group to "default:brick"'s definition, they still do not connect.
20:30 fluxionary  there's examples of something similar working in darkage, but darkage seems to have its own "register_wall" logic that doesn't rely on minetest_game
20:33 fluxionary  hm. seems to work if i use `override_item` instead of just mangling the connects_to list directly. *shrug*.
20:39 Krock       yes, you must push the definitions to Minetest again
20:39 Krock       i.e. minetest-register_item or override_item
20:40 Krock       minetest.registered_nodes modifications are Lua-side only
