15:19 Guest32804 trying to install RaspberryJamMod for python on Fedora 25 here, using this URL: http://linkis.com/serveur2jeu.info/5BSwE
15:19 Guest32804 but it shows this URL from the above does not exist: https://github.com/arpruss/raspberry​jammod-minetest/archive/0.20.tar.gz
15:19 Guest32804 what's the alternative?
15:22 jcalve cloning the repo in the mods folder?
15:24 Guest32804 jcalve: under socket folder, there's only dll files. Would those work in Linux?
15:24 jcalve no that's a windows thing

17:55 IhrFussel joined #minetest
17:56 IhrFussel WAIT...my server just crashed cause the code tried to lookup player information for a player who left WHILE the minetest_get_connected_players() loop was running
17:56 IhrFussel Are you serious? That will crash the server?
17:57 Natechip IhrFussel: Someone trying to get passwords and ips?
17:57 Natechip IhrFussel: Did you use whois?
17:58 IhrFussel Natechip, this line crashed the server in a for loop "if minetest.get_player_informat​ion(tuser).protocol_version < 27 then"
17:58 IhrFussel cause tuser was nil
17:59 Tmanyo joined #minetest
17:59 sfan5 tuser was probably not nil
17:59 IhrFussel for _,pnow in ipairs(minetest.get_connected_players()) do local tuser = pnow:get_player_name()
17:59 sfan5 minetest.get_player_information() probably returned nil
18:00 Hawk777 joined #minetest
18:00 IhrFussel sfan5, maybe this error message helps "ServerError: AsyncErr: ServerThread::run Lua: Runtime error from mod '' in callback on_chat_message(): ...inetest/worlds/oldserver/worl​dmods/own_commands/init.lua:215: attempt to index a nil value"
18:01 sfan5 it confirms my assumption that it wasn't tuser == nil but minetest.get_player_information(tuser) == nil
18:02 IhrFussel So I HAVE TO check for < 27 and ~= nil? ... meaning someone with an EXTREMELY old client played on my server?
18:02 red-001 no
18:03 red-001 well I don't think so
18:03 red-001 it should be 0
18:03 sfan5 you need to check that the player didn't leave in the meantime
18:03 IhrFussel Or how can minetest.get_player_information() return nil?
18:03 red-001 oh that must be it
18:03 sfan5 it can return nil if the player does not exist
18:03 jcjordyn120 joined #minetest
18:04 jcjordyn120 is account creation locked on dev.minetest.net?
18:04 IhrFussel So I have to add yet another check before checking the protocol version?
18:04 red-001 looks like it
18:05 rubenwardy jcjordyn120, ask Calinou
18:05 rubenwardy for an account
18:06 jcjordyn120 rubenwardy, thanks.
18:08 Calinou jcjordyn120: hi, PM me your email and desired username, so I can create an account for you
18:11 IhrFussel red-001, is Lua THAT slow with loops that it's possible to lose the player while iterating over it?
18:11 rubenwardy no
18:11 rubenwardy Lua runs on the server thread
18:11 rubenwardy so everything else is blocked whilst Lua is running
18:11 rubenwardy (apart from the mapgen threads)
18:12 red-001 isn't network in another thread?
18:12 rubenwardy Not sure
18:12 rubenwardy doesn't it send events though to the server thread?
18:12 rubenwardy in which case nothing should change for the server thread
18:13 rubenwardy ie: a client wouldn't just disappear
18:13 behalebabo joined #minetest
18:15 rubenwardy what's dstream?
18:15 rubenwardy https://github.com/minetest/minetest/blob/​723ab1a14a4a61486d31db022eb62794626cdf2a/s​rc/script/lua_api/l_server.cpp#L142-L267
18:15 rubenwardy that's the get_player_information function
18:15 rubenwardy what does your code look like?
18:20 Alcyone2 joined #minetest
18:21 Fritigern joined #minetest
18:27 Krock dstream sounds like debugstream
18:28 agaran joined #minetest
18:28 agaran Hello
18:28 red-001 pretty sure dstream is raw console output
18:29 Krock not directly. it's handled like each other lod output
18:29 Krock *log
18:29 Krock it just has the highest priority (LL_NONE) and can't be disabled
18:30 Krock the raw console output is called rawstream  or simply std::cout
18:30 Krock perhaps there's also an ingame notification if it's written into rawstream
18:43 glorfindel joined #minetest
18:50 IhrFussel rubenwardy,  but FACT is the player was suddenly lost in the MIDDLE of the iteration
18:54 rubenwardy would help to see relevant code

19:19 agaran hi IhrFussel
19:20 CalebDavis joined #minetest
19:20 IhrFussel tuser is the name of the current player in the loop
19:20 IhrFussel Hello there agaran
19:23 MinetestBot [git] Rui-Minetest -> minetest/minetest: Fix the serialization error by ff73c7a (#5964) 683ab3a https://git.io/vHy5d (2017-06-11T19:20:50Z)
19:28 GNU[BDC] some players get teleported outside map border. Anyone has this bug?
19:29 GNU[BDC] server 0.4.16 stable
19:29 IhrFussel GNU[BDC], was fixed after release
19:29 GNU[BDC] border is at 4500 they get at 24000
19:29 GNU[BDC] IhrFussel:  so i need dev build to fix stable bug?
19:29 GNU[BDC] IhrFussel:  thanks
19:29 sfan5 IhrFussel: don't call get_player_information twice
19:30 IhrFussel Correct
19:31 YuGiOhJCJ joined #minetest
19:33 IhrFussel sfan5, my code calls it for each player in the loop...is that wrong?
19:33 sfan5 no that's not what i meant
19:34 sfan5 do local x = minetest.get_player_by_name(tuser) and then if x ~= nil then if x.protocol_version < 27 then ...
19:35 IhrFussel local protv = minetest.get_player_informat​ion(tuser).protocol_version if protv < 27 and protv ~= nil then << that's what I have now...will see if it still crashes
19:35 sfan5 that doesn't work
19:35 sfan5 you need to check for nil first
19:36 sfan5 if you blindly do .protocol_version it is guaranteed to crash
19:38 IhrFussel sfan5, this should work now "if protv ~= nil then if protv < 27 then bcmsg = minetest.strip_colors(bcmsg) end end"
19:39 sfan5 no
19:39 sfan5 the problem is not that protocol_version is nil
19:39 sfan5 the problem is that the table that contains protocol_version is nil
19:39 red-001 ^
19:39 red-001 you can't index an non-table vaule
19:40 IhrFussel But I already check for if minetest.get_player_by_name(tuser) ~= nil then before that code
19:50 ThomasMonroe joined #minetest
19:50 ThomasMonroe joined #minetest
20:00 sfan5 IhrFussel: you need to save the value and then check it
20:01 sfan5 in theory the first call can return a table and the second one can return nil
20:01 Natechip IhrFussel: Your still working on this?
20:13 IhrFussel sfan5, how much time passes between the calls? They are literally neighbors

20:36 nac Minetest 0.4.15 on Debian 8.8. Where i put the /mod folder? Can i configure a own mod_path in my minetest.conf?
20:36 CalebDavis you put it in ./.minetest
20:38 agaran in technic, cable plates are just for make ones that look like mounting?
20:38 nac k thx
20:39 calcul0n nac, just in case, it's mods, not mod
20:40 nac ouh thx!
20:42 CalebDavis XD yep i didnt notice that
20:43 swift110 joined #minetest
20:43 nac a manual path to "mods" in the minetest.conf do not work?
20:47 sfan5 IhrFussel: it's unlikely yes, but instead of arguing you could just make sure a race condition does not happen and move on
