[ddnet/ddnet] Issue opened: #5074 Useless files included at link

I believe we can reduce the size of client, server and mainly tools binary by refactoring the cmake file. Pros : smaller distributed files Cons: might need more manual tweaking when adding or removing files For the client, the following files are included in the link, but actually not used: ```shell CMakeFiles/game-shared.dir/src/game/mapbugs.cpp.o CMakeFiles/engine-shared.dir/src/engine/shared/network_server.cpp.o CMakeFiles/engine-shared.dir/src/engine/shared/masterserver.c...

wow, i think we should maybe switch to nanoseconds

08:18

an update takes 4 microseconds times 0.1 = 0 casted to int xd

[ddnet/ddnet] Pull request opened: #5075 Switch to nanoseconds

Modern hardware is too fast, updates sometimes take less than a few microseconds. It's easier in the long run if we use a bigger range to avoid calculation problems. possibly f i x e s #5051 (needs testing from bencie for the main bug, but fixes what @sjrc6 found) Also took the moment to use more chrono so we can at some point switch to a typesafe time. Hopefully I didnt miss any value ^^

did anyone ever use DbgHitch?

09:44

@heinrich5991 is the antibot always compiled when ddnet server compiles?

I think we just put the .so file there, don't recompile it

ok

09:46

too bad, bcs would be easier if system would allow c++ signatures

09:47

@bencie do you have a github account?

09:47

maybe u can try #5075 later i dunno if that fixes the video rendering bug, but at least worth a try

Sure

bencie

Yeah the username is bencie.

real bencie???

No.

oh

10:05

cat

deen

I think we just put the .so file there, don't recompile it

Doesn't noby just provides the so to avoid sharing the code?

10:11

Or ur in his trusted list xd

10:11

(supposing you're using noby's ab)

heinrich is in his trusted list

Ah

10:13

Afterall noby's ab is written in C

10:13

nobyC*

nobys code is more like random hex numbers xd

10:13

that magically work

I mean idk how he can fcking work on that, even me when I look at his ab code I give up instantly

10:14

He's not even using any obfuscator

10:14

He's obfuscating by himself, that's why I call that nobyC

justatest

2

true

lmao

one of the few pieces of code that I gave up on reading instantly

Lol, noby madman

Learath2

one of the few pieces of code that I gave up on reading instantly

he's good but too lazy to write properly xD

doesnt he use a file based database

11:49

for fng

ah u mean simple txt file, not even sqlite?

11:50

probably, that's the easiest for him & fastest thing to do for him (edited)

ah yeah i remember the start of his server always took a while but i guess he already changed it

[ddnet/ddnet] Pull request opened: #5076 Add a CMake option to enable IPO

The main motivation is to reduce the size of binaries for release build (following #5074). The feature is not enabled by default because it increases the build time and the effect should be valued case-by-case. #### Linux Linux build time changed from 2:01 to 2:56 (with GNU gold) or 3:20 (default ld). | Executable | Before | After | | ------------- | ---------|---- | | config_retrieve | 886K | 43K | | config_store | 890K | 51K | | DDNet | 4.1M | 4.1M | | DDNet-Server | 1.6M | 1....

Figured out the performance issue, I was testing out a a cpufreq governor before I left for 2 weeks, I apparently never deleted that kernel I was testing out

gg

Ryozuki

doesnt he use a file based database

lmao wtf

14:44

why

cuz he is noby

14:45

isnt gnu gold slower than lld

thought the same, but have no benchmarks for lto

14:45

but mold wins tho

u mean ld ?

bcs it can do lto multi threaded afaik

14:46

lld

14:46

is from clang

14:46

or llvm

oh y llvm

14:48

so you guys have change the built in linker ?

no why

i mean by default i have ld, not lld

yes but we dont change anything

14:48

use what u want

14:48

i also doubt that pr goes through

14:48

tho LTO is nice, i also use it for my client

14:49

with ofast

14:49

legendary compile options

xd

14:50

ofast is the equivalent of o3 no ?

no

isnt exactly the same thing ?

its even more aggressive

ofast enables fast math

ofast also allows non standard stuff

mmh okok

"Disregard strict standards compliance. -Ofast enables all -O3 optimizations. It also enables optimizations that are not valid for all standard-compliant programs. It turns on -ffast-math, -fallow-store-data-races and the Fortran-specific -fstack-arrays, unless -fmax-stack-var-size is specified, and -fno-protect-parens. It turns off -fsemantic-interposition."

14:50

here the description from GCC

ok there are some additional features

its nice to find bugs in your code xd

14:51

bcs UB is often compiled differently with ofast

14:55

https://raw.githubusercontent.com/rui314/mold/main/docs/htop.gif lld vs mold

Embedded image

14:55

lmao i love gifs like these

14:55

they are kinda art

Jupstar ✪

lmao i love gifs like these

same

14:56

mold looks way faster wtf

ofc

14:56

mold is the state of the art linker

Embedded image

made by the lld author

Click to see attachment 🖼️

y i just saw this

the bigger ur program the faster it is

14:57

on ddnet it probs make little diff

lmao shorter is better (edited)

14:57

imagine you need to read it

gnu gold sucks hard xd

Ryozuki

on ddnet it probs make little diff

might be imagination but feels a bit faster

who use gnu gold ?

idk

14:59

before lld existed it was the best i guess

GPL enjoyers xd

lld and mold are from the same author

14:59

tthat guy is a genius

gold was about 3x/4x faster than LD.

ah yeah

14:59

ld

kinda cringe

xd

Why does the speed of linking matter?

>

If you are using a compiled language such as C, C++ or Rust, a build consists of two phases. In the first phase, a compiler compiles source files into object files (.o files). In the second phase, a linker takes all object files to combine them into a single executable or a shared library file.

15:00

lmao

15:00

the github repo mentions rust

15:00

based

15:00

mold is written in C++20, so if you build mold yourself, you need a recent version of a C++ compiler and a C++ standard library. GCC 10.2 or Clang 12.0.0 (or later) as well as libstdc++ 10 or libc++ 7 (or later) are recommended.

15:00

more based

y the linking step is important too

15:01

i have gcc 11.2.0

15:01

ez

i have clang 15

@Jupstar ✪ mold is agpl

uff

thats good

15:03

no reason to use gnu gold

he has to be dead for 70 years before copyright lifts

15:04

there is nothing good about copyrights

u live in germany

but most software today wont be used in 20 years anyway

they dislike public domain there

so who cares xd

so agpl is the next best thing

CC0 or nub

to contribute to sqlite

15:05

u have to sign things

Ryozuki

to contribute to sqlite

xD

cuz public domain

15:05

countries suck at public domain

how the fuck can i know which linker im using ?

what compiler do u use?

i mean its obvious im using ld but how can i find the version

-DCMAKE_EXE_FLAGS="-v"

15:07

should tell you i guess

Nagi01 {LAN}

who use gnu gold ?

Who use CMake 2.8.12? It is nine years old. Who use 0 instead of nullptr? Even nullptr is 11 years old. Who use virtual instead of override? You know, there are some projects...

xd

15:07

who doesnt use c++23

dont u have to use virtual with override?

Ryozuki

dont u have to use virtual with override?

y wtf

no

Kaffeine

true story

u only need virtual for the base instance

15:08

all others just use override

15:08

no virtual keyword is needed

u need

15:08

for the base

15:08

u said it

y just for the base

y but someone added virtual ... override into our codebase

15:08

i saw that recently xd

[ddnet/ddnet] Issue opened: #5077 Dummy hammers on release of cl_dummy_hammer when cl_dummy_control is turned on

Steps to reproduce: bind x +toggle cl_dummy_hammer 1 0 cl_dummy_control 1 Press the key you bound the command to above, and you will notice usually the dummy hammers twice. Sometimes it doesn't, and I'll explain why: The delay for hammer is 120 ms (if you don't hit a tee). If you press the dummy hammer button, and release the button before 120 ms passes by, the dummy will only hammer once. If you hold down the button for longer than 120 ms and then release, the dummy will hamme...

anyway, from the devs except maybe chrain most use arch i think (except me xd)

Jupstar ✪

y but someone added virtual ... override into our codebase

It made some sense 10 years ago — when someone still used to place virtual to the overridden methods. Yet, having override allows to catch some bugs (and thus simplify refactoring).

just use c++17

15:10

deen also upgraded to debian 10

15:10

who uses c++? use rust

15:11

should have added

15:11

at the end

Ryozuki

who uses c++? use rust

yes pls start

15:11

we need a leader

Jupstar ✪

deen also upgraded to debian 10

and ddnet is from 2013 xd

15:12

so 9 years

15:12

find the error xddd

Ryozuki

@Jupstar ✪ replace gameworld with https://github.com/skypjack/entt

yes minecraft components

15:13

lets go

not c omponents

15:13

its a ECS

15:13

imagine using all cores

sounds cool

15:13

but look at our codebase

15:13

how can u not break everything xD

15:13

even changing 1 line often causes bugs xD

ye

ddnet.tw offline, is that intentional?

i doubt also just saw it

15:55

@deen u are needed

15:55

deen: ^

15:59

btw @deen @heinrich5991 https://master1.ddnet.tw/ddnet/15/servers.json failed. libcurl error: Operation too slow. Less than 8000 bytes/sec transferred the last 10 seconds in this rare case my browser does not fail to download it (just takes over 10 seconds) while the client does

16:00

maybe it should still keep trying or smth but already act like it failed

its possible to change the ping (server side) ?

why 0 server?

Is it possible to have clipping feature work like a tileset? So that you can cut out round shapes, corners and areas that aren't connected to each other?

u can do anything, just need to break compability with old clients and vanilla

i know how it sad is to maintain legacy code

Jupstar ✪

y but someone added virtual ... override into our codebase

i almost made a pr for this

17:35

then i thought that it was kinda useless

Jupstar ✪

anyway, from the devs except maybe chrain most use arch i think (except me xd)

please don't scorch my name

its not ur fault

17:36

its your work place xd

uh?

werent u forced to use ubuntu 18?

ah, i won't upgrade before finishing my manuscript

17:38

too many risks

17:39

but i still compiled gcc12 and clang12 somewhere

arch chad

xd

the problem is that gcc12 links to its own lib and then the binary wont find them if i don't change LD_LIBRARY_PATH

imagine not using arch

17:55

in 2022

17:55

bruh
