@Jupstar ✪ any chance to build a new mobile client for him?

I'm not sure if that still works since the rust support :/

09:53

And restoring the old controls is probs lot of work too xd

watf is he playing touch or with external mouse?

09:55

if its touch i wanna see camera footage or didnt happen

09:56

also trol deen for having the url at the bottom

I don't remember touch support being in client, but I assume the android version is very old so maybe it was removed (edited)

I'm not sure if that still works since the rust support :/

I'd be willing to help with the rust support

I haven't played the PC DDNet.

09:57

insanity

i would start over tbh. isn’t that piece of work on gles1

I believe the app would only be great if it was for spectating and chatting only, not for playing

all UI is a NIGHTMARE and the client is so old that basics like antiping aren’t there

this mf started playing in 2022 mobile only and exceeded my decade of pc tryharding omg

09:59

in points

I’ve seen this guy on usa

09:59

never suspected mobile

09:59

maybe trolling

Yes was removed

10:01

I once proposed a mouse change to make touch ez to integrate. But MacOS is the least game friendly environment sadly xd

this mobile player needs a medal

10:11

and a new android release asap

Tell em to bring him his new release

rust can compile for Android

10:29

ndk

<Jupstar> I guess I also prefer to focus on next-gen teeworlds for now, but i can gladly assist with build script information and quirks for android

10:36

<Jupstar> if someone is motivated

Ryozuki

rust can compile for Android

I have no doubt about that. It's more about the cmake build setup and if the libraries support it(if we use libraries that do non std stuff)

Hey does someone have the link to the accounts issue on github?

[ddnet/ddnet] Issue opened: #6893 Should we accomodate building the headless client with as few dependencies as possible?

Pro: easier to build minimal container images. Should we even support that? Con: maintenance overhead CC #6889 CC #6891 (might also be useful regardless of this issue, apparently openSUSE doesn't ship libnotify?)

<Jupstar > chillerdragon when rename headless to surfaceless

thats not a thing

<Jupstar > do you disable anything else besides graphics?

11:45

<Jupstar > well u want libnotify disabled, but i guess its kinda part of graphics

it tries to keep most ddnet code

11:49

just being low on dependencies during compile and runtime

@heinrich5991 u know if a packed struct can have a align >1?

packed struct has align 1

11:55

so no, it cannot

f

why?

no reason

11:57

well cuz smth at work

Do u have to use rust?

its llvm

Pragma pack 2

11:58

Does not work?

i mean its not c++ either

11:58

its llvm ir

I don't know about llvm

11:58

my answer was about rust

yeye

11:58

but it makes sense to ask what rust does too

11:58

cuz it uses llvm

11:59

but according to my findings packed structs have align 1 ye

11:59

@heinrich5991 ever used the Layout struct from rust?

11:59

its awesome, it calculates padding, alignment, etc for mixing fields and stuff

have not. I think it's a new thing :p

yea

12:03

<Jupstar > i find the disadvantage a pretty huge disadvantage

12:04

<Jupstar > (a practical usecase)

12:04

<Jupstar > theoretically it's clear to me what the advantage is

@Davide :c

12:05

time to play w vpn i guess

we have a JIT engine from MLIR, we deserialize the inputs from json and allocate the resulting structures in the arena and pass it to the jit executing a function with those inputs, returning the outputs as pointers which we serialize back to json

12:06

it also works with natively compiling, in which case for now we call the method using a wrapper C program

12:07

static void run_bench(return_values_t *, void *, uint64_t)
    __attribute__((weakref("_mlir_ciface_main::main::main")));

12:07

which is why i once asked this weakref stuff time ago

12:07

kek

12:07

@Jupstar ✪ bumpalo works best when u want fastest allocation and dont care about deallocating

<Jupstar > man ur job is so interesting

all ppl asking "client" questions in developer channel is just me under different names

12:13

@Jupstar ✪ btw

12:13

in ur rust tw client

12:13

do u use mimalloc?

just change the default rust global allocator

12:14

to go blazingly fast he doesnt do allocations at all

12:14

he just pipes frames straight out of /dev/urandom because its webscale

ah mimalloc has no wasm rn

yo btw https://github.com/ddnet/ddnet/blob/master/scripts/compile_libs/gen_libs.sh here on the lines where it calls the other files it should be bash instead of ./ atleast it failed for me with a ./ even though the files had execution rights. ll. 85, 108, 120 (edited)

yea but they already had execution rights

im on arch btw ;)

<Jupstar > I've really never heard of such an issue and also never encountered it, is maybe "#!/bin/bash" missing in these files?

12:31

<Jupstar > the ones that fail

Jupstar: because they don't want every rust program to ship with an allocator (edited)

ws-client

<Jupstar > does that ever make sense? xd

when i executed them by hand they worked fine

they use the system allocators instead

<Jupstar > @heinrich5991 so the one ryo posted does some kind of pre allocations and then represents a heap on its own?

probably uses the OS page maps to create their own allocator

mimalloc is a drop-in replacement for malloc and can be used in other programs without code changes, for example, on dynamically linked ELF-based systems (Linux, BSD, etc.) you can use it as:

<Jupstar > @Teero i really dunno if this is not allowed in strict bash or smth. i always used it like this :D

free list sharding: instead of one big free list (per size class) we have many smaller lists per "mimalloc page" which reduces fragmentation and increases locality -- things that are allocated close in time get allocated close in memory. (A mimalloc page contains blocks of one size class and is usually 64KiB on a 64-bit system).

>

free list multi-sharding: the big idea! Not only do we shard the free list per mimalloc page, but for each page we have multiple free lists. In particular, there is one list for thread-local free operations, and another one for concurrent free operations. Free-ing from another thread can now be a single CAS without needing sophisticated coordination between threads. Since there will be thousands of separate free lists, contention is naturally distributed over the heap, and the chance of contending on a single location will be low -- this is quite similar to randomized algorithms like skip lists where adding a random oracle removes the need for a more complex algorithm. eager page purging: when a "page" becomes empty (with increased chance due to free list sharding) the memory is marked to the OS as unused (reset or decommitted) reducing (real) memory pressure and fragmentation, especially in long running programs.

>

secure: mimalloc can be built in secure mode, adding guard pages, randomized allocation, encrypted free lists, etc. to protect against various heap vulnerabilities. The performance penalty is usually around 10% on average over our benchmarks.

>

first-class heaps: efficiently create and use multiple heaps to allocate across different regions. A heap can be destroyed at once instead of deallocating each object separately. bounded: it does not suffer from blowup [1], has bounded worst-case allocation times (wcat) (upto OS primitives), bounded space overhead (~0.2% meta-data, with low internal fragmentation), and has no internal points of contention using only atomic operations. fast: In our benchmarks (see below), mimalloc outperforms other leading allocators (jemalloc, tcmalloc, Hoard, etc), and often uses less memory. A nice property is that it does consistently well over a wide range of benchmarks. There is also good huge OS page support for larger server programs.

<Jupstar > yeah @Ryozuki but it must have some disadvantages :D

12:34

<Jupstar > oh ok

size

<Jupstar > here it comes xD

12:35

<Jupstar > i mean its worth a try, but i generally try to reuse memory anyway without any allocators ^^

the best allocator is the stack kek

Jupstar ✪

i lately saw this: https://github.com/spuhpointer/stack-vs-heap-benchmark and was surprised and did some own benchmarks, bcs i wanted to reduce some heap allocations in my app. If you actually fill the data structure you allocated, it's indeed very close between heap and stack.. If you use smth like clone_from it's ofc MUCH faster with an preallocated buffer. But if you copy every element one by one it's almost same speed.. similar to the graph shown in this benchmark https://raw.githubusercontent.com/spuhpointer/stack-vs-heap-benchmark/master/filled2.png (edited)

^ this also interesting

@Jupstar ✪ Is there a reason why memory for texture data in graphics commands is allocated with malloc whereas other commands use the command data buffer? Seems like we currently leak the texture data memory if AddCmd fails.

<Jupstar> @Robyt3 it can't fail ™

13:37

<Jupstar> if it fails it flushes the command queue

13:37

<Jupstar> and if the queue is flushed its empty

13:37

<Jupstar> and the CMD is never too big then

13:38

<Jupstar> textures as well as buffers use malloc bcs they can be very huge

13:38

<Jupstar> and the command data have a limit of a few kb or maybe mbytes

I see, hard to understand code though

13:40

If it can't fail twice then we should assert and make AddCmd return void

<Jupstar> yeah vanilla tends to never use dynamic memory

13:41

<Jupstar> do we never handle the fail path?

13:41

<Jupstar> then we can probably do that

Seems like in some cases we just return early

can u link to code

13:41

Search for AddCmd

13:42

In some cases it's in if-statements, but in many it's not

13:42

This would also be a way for a texture handle index to not be freed correctly, but if AddCmd never fails then it's not that

<Jupstar> from feeling i'd say if we ever fail, it's an fatal error anyway

13:43

<Jupstar> i would know if most code could recover from this

13:43

<Jupstar> would not*

13:44

<Jupstar> @Robyt3 i really have the feeling we have a buffer overflow somewhere. or the crash logs are really bad

13:44

<Jupstar> and dont show the actual bug

13:47

<Jupstar> i'd highly suggest to not handle content bugs like this anyway. Fail where the content is loaded. for skins for example don't load the whole skin is one part fails. then we can safely assume that there are no invalid textures

13:47

<Jupstar> that's also why i dislike that we allow having no data dir

13:47

<Jupstar> they must be a default skin

13:47

<Jupstar> and a default entities

13:47

<Jupstar> and default whatever

13:49

<Jupstar> it also minimizes the chance such content is shared in the community bcs it does not work at all. that also worked with the warnings :D ppl were mad first but now i havent seen it in a longer time

<Jupstar> i dunno how much time you want to waste, but e.g. for maps, we currently dynamically load anything that is compressed. In my tw version whatever loads the map has to directly tell which stuff it wants to load. This allows to validate the map files directly at loading. and it also increases performance

13:57

<Jupstar> because the whole code works on memory instead of files

13:58

<Jupstar> so if u want to improve that you could think about redesigning how maps, skins etc are loaded xd

14:01

<Jupstar> dynamically load anything that is compressed when used the first time*

the error says that it can't find the libs but they were created and are in the ddnet-libs folder in the root directory

<Jupstar> how does your ddnet-libs look like, e.g. for ogg

I dunno if u should delete ddnet-libs. I could imagine header files are not copied

yea i overread that you need to merge both of the ddnet-libs... but there is one more problem over and this is sqlite i rebuild the ddnet-libs after i installed mariadbclient but i still get here the error that sqlite3 -> no such file or directory amd its the only small folder in it with 12k rest over or close to 1m (edited)

here are the last loglines of that

15:37

btw im using ubunutu feelsscary

well sdl2 thing is clear why it fails

15:47

sqlite3 is weird

15:47

ah

15:47

u dont have 7zip installed

15:48

for sdl2 u have to modify the script and pin a current sdl2 version

15:48

or rename libsdl3.a to libsdl2.a manually ^^

15:48

no idea if that will work with different headers tho xD

let me test it

Daniel

let me test it

function build_cmake_lib() {
    if [ ! -d "${1}" ]; then
        git clone "${2}" "${1}"
    fi

        # THIS IS NEW
    if [[ "${1}" == "sdl" ]]; then
        git checkout release-2.28.1
    fi
    (
        cd "${1}" || exit 1
        cp "${CURDIR}"/scripts/compile_libs/cmake_lib_compile.sh cmake_lib_compile.sh
        ./cmake_lib_compile.sh "$_ANDROID_ABI_LEVEL" "$OS_NAME" "$COMPILEFLAGS" "$LINKFLAGS"
    )
}

in gen_libs.sh

15:59

for sdl checkout a 2.x tag

15:59

if tags are not auto downloaded with your git, you can try release-2.28.x

i dont need sdl like i only need DDNet-Server

oh ok

Daniel

i dont need sdl like i only need DDNet-Server

why do u want to compile the server to WASM?

16:11

i hope you are aware that WASM over a browser does not offer UDP in any kind

16:11

and i am not sure if u can host a websocket server either

mhh. haven't thought about it yet but when you say it like that it sounds logical with the udp. @Teero and I had played around a bit and built a ui with some info for fun and wanted to see if we could get that with wasm in the browser.

16:18

yeah dunno got harder xdd

is there a point where it fails?

i cant even compile openssl anymore

@mAdIM making a master server i understood the second part i did not understand what do you mean by adding a list server on the client? you mean make your client talk to your master server instead of ddnet master server?

Thank you very much for your help It was meant to show my own servers in the section I added "my server"

ok will do thanks for the research lerato

Had to boot with a live usb, chroot in and reinstall just every package because it was so broken

average archlinux moment

ChillerDragon

how can pacman do kernel updates if /boot is ro?

idk how it managed to delete my kernel, it wouldn't remount it rw just on it's own right?

19:00

a its in here

19:00

thats not the master server is it?

19:00

is info.ddnet.org open source?

it's just a served json file iirc

19:02

don't remember what generates it

@mAdIM idk what you are building but i wouldnt setup a master server only for that tab :D just hardcode it in the client the list of servers you want to add there

19:03

if you want it to update then do it like ddnet

19:03

serve a json

19:05

something funny i found

20:40

some servers dont evenn list a clients [] array

20:40

at all

weird

20:41

which servers are those?

20:41

I think the client will reject them

yeah but the master not

20:41

i dont know rn, i didnt specifically save em, i just found i had to filter for that too

the master doesn't but who puts up servers that the client doesn't list?

I think I'd prefer if each server entry didn't have a lot of different colors

yeah i mostly copied the design from another web i have

20:44

its just work i did in 1 hour
