@Learath2 we don't put sqlite3 for mac in ddnet-libs and it seems like it doesn't want to use the version I install to linux so I have no idea how deen is able to cross compile from linux to macos

04:05

this is the only thing it's missing, it finds everything else

Deleted User

okay, for some reason sqlite only provides an autotools configure script You might be able to cross-compile sqlite3 like this: CC=target-triple-idk-clang ./configure --prefix=<wherever darwin-x86_64.toolchain specifies> --host=x86_64-pc-linux-gnu make install though autotools is so bad and flaky this may well not work

this guy has the same issue 1 year ago

04:06

the resolution was "cross compilation doesn't work"

04:06

but yesterday we decided native compilation doesn't work

04:06

so I'm confused

04:09

it used to exist, why did we get rid of it

04:11

it got deleted here https://github.com/ddnet/ddnet-libs/commit/ae0eb60903b612f3d8c0b5a2f2661c9f14710fbf

does deen not cross compile?

Deen does have a Mac, so I expect he just compiled on that

Learath2

Also I think our official mac build is still crossbuilt from linux, it might be an issue there too

I was told this

What is the poll in #announcements about?

Why not just ask deen? @deen do we still cross compile for mac or do you do a native release nowadays?

At least you don't get disconnected anymore

You just need to retry a second time to connect the dummy

[ddnet/ddnet] Issue opened: #9578 Freezebar not shown while standing in kill tile after finishing

Tees can stand inside kill tiles without being killed or frozen if they are in a team with another player and have finished already. In this case, the freezebar is not shown, because it is assumed that being inside a kill tile always kills or gives freeze again.

ChillerDragon

yo @Davide connecting a dummy on ger3 is a bit wonkey sometimes he just doesnt want to connect

Same, cannot connect dummy on server tho

a drawback to not needing to verify yourself on ger10 anymore. the same reason you now have a small delay when joining, i guess it just drops the attempt to connect the dummy

10:59

i guess this could be fixed on our side rather than davides tho

trying to test my fix for https://discord.com/channels/252358080522747904/757720336274948198/1332659743507873822 and also learn some mapping basics, how can i place kill tile in editor

or other tiles as well if not opening an existing map

on the left side, the Game group and layer are selected by default just press space, the tile selector will pop up

<ChillerDragon> what is nicer for a list of urls? A config with comma separation like sv_urls https://foo.com,https://bar.de or a command like add_url https://foo.com add_url https://bar.de

12:58

<ChillerDragon> not for ddnet btw

command-based imo

12:59

just feels more flexible

<ChillerDragon> i think so too

12:59

<ChillerDragon> makes the config file look nicer because of multiple lines vs long lines

exactly

<ChillerDragon> but then it also needs stuff like remove_url or clear_urls

also makes adding/removing em easier, depending on the size

<ChillerDragon> which the user has to figure out

ye

13:00

i mean having add_url del_url/rem_url is sane either way

<ChillerDragon> but the comma also has to be figured out so ...

13:00

<ChillerDragon> del or rem :D

maybe you can have both? `have add_url "https://foo.com; https://bar.de" work, but adding it as 2 seperate entries

<ChillerDragon> wowowo

13:01

<ChillerDragon> but then it doesnt have the edit/remove capability

remove by index

13:01

add list_url(s) aswell kekw

kekw

<ChillerDragon> oof poor user

13:03

<ChillerDragon> sv_register uses the comma array for example

but it only has two options

<ChillerDragon> so does sv_register_extra

i can imagine it get really messy really quickly

<ChillerDragon>

MACRO_CONFIG_STR(SvRegisterExtra, sv_register_extra, 256, "", CFGFLAG_SERVER, "Extra headers to send to the register endpoint, comma separated 'Header: Value' pairs")

depending on how many url's are needed for whatever you're thinking about

<ChillerDragon> i am working on multiple http end points stats are sent to on a round end

13:04

<ChillerDragon> but i am wondering in general

13:04

<ChillerDragon> i had the same question while thinking about redirect tiles

13:05

<ChillerDragon> the command seems a bit supirior but it only shines if we actively start using it with a unified interface

13:06

<ChillerDragon> i think i am going for the comma variant for now just because it is easier for the user to figure out especially if only one url is needed which is the most common case

13:07

<ChillerDragon> but one day we should develop some array config standard for ddnet that works well with multiple values

13:08

<ChillerDragon> maybe config files just need a way to support newlines with a backslash then you can have config variable values spanning multiple lines

13:08

<ChillerDragon> but what if the values can contain commas?

ws-client

<ChillerDragon> but what if the values can contain commas?

what kind of values should contain commas? floats are dots, and no other variable is in need of comma seperation

13:09

right?...

13:10

i guess custom servers could have that, e.g hook_rgb 100,100,100 or smth

Solly

would it be possible to add the hashed timeout code to the server json list for the purpose of clients identifying eachother (using auxillery server)

Sharing the timeout code in any way shape or form Is a bad idea

meloƞ

Sharing the timeout code in any way shape or form Is a bad idea

you would have to try very hard to unhash a timeout code

14:55

thers also multiple timeout codes (millions) which create the same hash (depending on the size of the hash)

14:56

and you have to guess the right one before getting ratelimited (idk if there is, i guess chat/command rate limit)

14:56

and also the person has to have timed out

14:56

and what risk is there

14:56

someone is now playing under your name

14:57

unless theres also an account system

14:57

but the risk is .. minute anyway

14:59

adding any other way for clients to identify eachother (or to share arbritrary data, but that wont fly) would also work

14:59

could be in the same way timeout codes work.. but not used for timeout recon (edited)

Solly

adding any other way for clients to identify eachother (or to share arbritrary data, but that wont fly) would also work

identification never will be added to the client to preserve privacy

Avolicious

identification never will be added to the client to preserve privacy

the code would be unique per connection

15:01

accounts allow clients to identify eachother (if clients can see if other clients are verified, probably via some 0 info thing to prevent servers from faking it) but is more persistent (account id or whatever)

@ChillerDragon for spamming an endpoint with countless packets the closer to the source you get rid of the packets the better because often you have more bandwidth and cpu to deal with it cloudflare has terrabits of bandwidth to soak up ddos attacks your router has gigabits (if youre lucky) and limited cpu time your computer/server has a slice of that (if youre lucky) and limited cpu time the software will probably crash or grind to a halt services like cloudflare will be more prepared to deal with attacks = less downtime & no crashing than you iptable blocking suspicious ips it will also be prepared to deal with more than just spamming, like slow loris attacks (edited)

20:18

"the closer to the source" or rather the further away from your software, minimizing the attack surface and reducing wasted bandwidth and cpu time
