how do we garantuee packages on steam btw? e.g. we dont ship curl is there some setting in steam that checks packages for existence or does it simply fail, if the required package is not installed?

Hofstadter's law

Hofstadter's law is a self-referential adage, coined by Douglas Hofstadter in his book Gödel, Escher, Bach: An Eternal Golden Braid (1979) to describe the widely experienced difficulty of accurately estimating the time it will take to complete tasks of substantial complexity: Hofstadter's Law: It always takes longer than you expect, even when yo...

how do we garantuee packages on steam btw? e.g. we dont ship curl is there some setting in steam that checks packages for existence or does it simply fail, if the required package is not installed?

we just hope that curl is installed

ok, then we can also hope that the vulkan loader is just installed xdd

12:52

how do you link against libraries for macos? molten vk for example

libcurl is installed basically everywhere @Jupstar ✪

we include on macos what isn't by default on system

yeah ok, then ffmpeg or whatever

we include that

i mean for linux

12:53

was answering heinrich

steam has a dependency for libcurl

steam package suggests vulkan

12:54

i mean it kinda makes sense since DXVK is used alot by steam play

12:54

but its not dependency

steam also still chills on 32bit, i guess the dependencies are only 32bit then anyway (?)

@deen i guess we should build dr mingw with the patches here https://github.com/jrfonseca/drmingw/issues/32 ASLR on 64bit makes it impossible to recover the addresses

Dump also module base addresses in ExcHndl · Issue #32 · jrfonseca/...

With ASLR enabled in the process, the DLLs are loaded to a random location, so the PC addresses in the stack trace cannot be used directly to assist debugging. It can be helpful if the base address...

15:31

under wine it simply didnt do this, so i didnt see it

oh no

15:33

I don't think it's great to take 3 unreviewed changes from 2018

15:34

I'm wondering why they don't fix it. Disabling ASLR is also not great

why not add it

15:34

the patches are like 100 lines

15:35

actually probs only like 50 lines xd

because then I have to make sure they keep applying

15:37

would be better if they can be submitted upstream

15:37

I haven't even tested dr.mingw, so i won't be able to judge if everything is fine with the patches

the upstream code is also from feb 2021 XD

15:38

i tested only 32bit on windows and 32bit ASLR is just a static offset

15:38

but 64bit does crazy stuff

Jupstar ✪

i tested only 32bit on windows and 32bit ASLR is just a static offset

(an ez to guess one to be precise)

15:38

probs bcs limited address space

ASLR exists to be unguessable ^^

yeah but 32bit ez af xD

it's one of the last lines of defense protecting users against exploits

just replace the first two hex numbers with 40

@heinrich5991 I couldn't find where in ddnet's code it explicitly allows connections of the same port when someone is timeoutprotected

16:39

can you try and find that for me? My guess it its in GetClientSlot() just returning the old slot instantly

16:40

but in that case it should work on my server too, since it checks for a current slot first aswell

[ddnet/ddnet] Issue opened: #4757 Database connection failed, teamsave stored in sqlite

@Zwelf I noticed these failures will always use the random 3 word password, which is then unguessable for the players. I'm not sure if there is a good way to solve this, just using their pw will fail when it already exists in real db. Ideal would be to try the proper pw if it's unused, otherwise generate the 3 word one so we have it for admins to look up at least. Or maybe we should keep trying saves for a longer time instead of failing so quickly?

on private server. if login as main i cant use commands as dummy even if logged in how to fix?

known bug, isn't fixed yet

19:23

sorry

ok thx from noctua it was his problem ^^ (edited)

Oh nice the dummy rcon is a ddnet issue? I was sure it’s my fork and I procrastinated looking into it since forever

yes

Awesome!

[ddnet/ddnet] Issue closed: #4753 Prediction makes feet flicker while standing on 255 jump tile

But it’s super old. How come It’s the first time I hear about it in ddnet.

no, was introduced in 15.9

21:32

if you had it before, you have a different bug

21:32

and I just set bors r+ on the fix for it by heinrich5991

Do you know when the bug was introduced? Maybe 15.9 was released recently and there are just not enough nightly running dummy using rcon users

21:34

I do merge with upstream a lot

21:36

Yea I try to report issues more and faster and check if it’s a ddnet issue. To help released get more stable. :)

just check yourself: https://github.com/ddnet/ddnet/issues/4721

I feel kinda guilty letting a bugged rls happen when I could have stopped it.

yes, would just have to check if the same bug happens in ddnet

Yes
