A lot of servers seems to be down

00:34

@snail ?

ok, all servers appear to off when nobody is playing on them and didn't turn on back

@deen uhm, did you do sth?

except for Persian, it's alive

I think that fixes all of them

yeah, nicely done

I got in top 10 today. after discussing it with others, it became clear why

I misread the problem statement

@heinrich5991 congrats

08:47

@Learath2 I updated the server, nothing else

08:48

Thanks for the workaround @Learath2

oh yea, thanks for being around to fix the servers @Learath2

Maybe the middle of the night is not the ideal time for our scheduled server restarts

08:51

I think when I set that I used to be online around that time and could react, but not anymore

[ddnet/ddnet] Pull request opened: #3391 Export all symbols from the main executable for the antibot

Add -rdynamic if supported by the linker. Not all symbols being exported broke our builds recently, the antibot library used mem_comp from the main binary but it wasn't exported, leading to the following runtime error: ./DDRace64-Server_sql: symbol lookup error: /home/teeworlds/servers/libantibot.so: undefined symbol: mem_comp

what happened?

or is it secret info

i wanna know too o_0

why did that only recently cause an issue

idk

oof

maybe a change in compiler

sry?

./DDRace64-Server_sql: symbol lookup error: /home/teeworlds/servers/libantibot.so: undefined symbol: mem_comp error message was here

afaik i mostly used memcmp not mem_comp anyway

*this, you can also see it in the pull request

09:31

yes, it's my fault anyway, if you want to blame someone

09:31

it's only an issue because I added the glue code

Oh what was it?

heinrich5991

yes, it's my fault anyway, if you want to blame someone

i dont want to blame someone i was just hoping i didnt fuck something up again lol

Just woke up :P

apparently the compiler stopped exporting mem_comp from the binary for the shared libraries

gm

but libantibot-noby.so used it and couldn't find it

09:32

-rdynamic exports all the public symbols again (edited)

09:32

usually it uses a heuristic at build time which symbols to export

Huh, how can the compiler not export that? It's a symbol with external linkage no?

it only exports those used by the shared libraries it can see at build time apparently

09:33

but that doesn't work for our setup where we only give the actual binary to the program at runtime

Huh, is that even a legal aasumption to make?

why cant we use memcmp instead

I didn't feel like tracking down every function we use from the main binary ^^

i meant bcs its string.h standard fn

Anyway, did you find a way to fix it?

or is it a compatibility thing

huh smart

libantibot-noby.so -> libantibot-nobo.so

no u

not my fault pepeH

ah github dark

09:36

so many years

I used it for 1 minute and went back to white

@deen took me a couple minutes to figure out what was even happening. We should prolly add something to run64 to stop trying to restart and warn us

is there a way to save backtrace and restart the executable

I think I like the new dark modd

@noby search for "coredump". they're usually saved when a program crashes

09:38

try it with a simple C program that crashes

@Learath2 I wouldn't necessarily stop, but at least warn sounds good. But an email per failed run would quickly explode

We already have coredumps but I don't think this caused a coredump

09:38

Or I couldn't find one anyway

nope, it's not a crash when it doesn't even start

it starts

09:38

it only detects at runtime that symbols are missing

09:38

not sure how it quits

oh

deen

@Learath2 I wouldn't necessarily stop, but at least warn sounds good. But an email per failed run would quickly explode

Need to be smarter than 1 mail per fail :D

I use https://healthchecks.io/ for this kind of monitoring (e.g. for certificates, or teehistorian downloads)
