[Festus1965]

Inside 24 hours I had 2 crash on "Asia Thailand" as
* of nil player_name in mod EUban

Code: Select all

2020-03-16 07:37:35: ERROR[Main]: ServerError: AsyncErr: ServerThread::run Lua: Runtime error from mod '' in callback on_prejoinplayer(): /home/thomas/.minetest/mods/euban/init.lua:262: attempt to index a nil value
2020-03-16 07:37:35: ERROR[Main]: stack traceback:
2020-03-16 07:37:35: ERROR[Main]: 	/home/thomas/.minetest/mods/euban/init.lua:262: in function 'is_banned'

and then one more crash
* with same reason in mod showbones

Code: Select all

2020-03-16 17:34:18: ERROR[Main]: ServerError: AsyncErr: ServerThread::run Lua: Runtime error from mod 'showbones' in callback on_leaveplayer(): /home/thomas/.minetest/mods/showbones/init.lua:269: attempt to index a nil value

Could that be, or what might have been happened ?

Are you storing objectrefs?

This could happen with an expired objectref, or if a mod is providing fake players

As always, please provide the code so we can see

A: Not that I know -
B: how to know if a mod uses fake players ?
C: I am using original mod code (so I linked there source in 1st post now)

and as this didn't happen for about a year, this often repeat same happening just now inside 24hours don't seam to have a reason in still same wrong code, more likely in something new in a client or method about or like hacker ...

The code of the mods were ok.
The solution for me was the update to the newest version of minetest at the server.
Greetings, Clyde.

The solution for me was the update to the newest version of minetest at the server.

What is newest to you:
* final stable = 5.1.1
* or what kind of safe, sure dev Version with 5.2.0 ?

[Clyde]

Directly from git with compiling and installing.

your all so funny: old versions, stable and dev are all on git, where I take them all from ... hihi, so mean, your answer didn't help anything yet. so
* sudo add-apt-repository ppa:minetestdevs/stable
* etc.

Code: Select all

git clone https://github.com/minetest/minetest.git

and after cmake and install = my actual and problem seen above (5.1.1),
as at 5.2.0-dev I saw that command "/revoke shout player" and the player still could talk in chat, so back to 5.1.1 and not sure as that problem was from dev or hacked-clients

I'm sorry about that, the server list tells me 5.2.0-dev.
I compile it with the flag -DCMAKE_BUILD_TYPE=Release.

This i've not tested, but i will do it, i can revoke myself the shout-priv and try to chat, this should show me enough.

Seems you missunderstood me, i talked about my server, where i had a similar problem and was hoping, this information helps you.

I know your server, i'm sometimes there ;-).

[Festus1965]

then better we stop the discussing here, as of too much miss = understand
