a93cf79 A Hedgehogs - ddnet-maps

@Deleted User: this worked LD_LIBRARY_PATH=$PWD ./DDNet

08:45

in 0.17 there is actually no blackscreen anymore but its still not instant :/ i can watch the window closing

08:52

08:52

also which crackhead skipped release of .15 omnagwd

15 is just like 11 and 17 dev versions

i join nori in the sdl hater gang

they dont garantuee a stable API

so what commit/tag you recommend me to bisect?

mhh

08:54

.14 should be fine

isnt that old then?

yes

oke lol

good luck climbing the binary tree xd

thanks mate

08:55

i will actually try git bisect this time

08:55

i usually do it by hand

yeah bisect gives you the fastest possible way without guessing

i cant find an open or closed issue for this

08:58

but maybe im too stoopid to read sdl issues

08:58

i rly can not belive that im so alone with this .-.

08:59

i thought i use a pretty mainstream setup

sometimes fixing other issues also fixes yours

ah yas babe

09:00

so nice!

09:00

.14 goes brrrrrrrrrrrrrrr

09:00

should i just yeet on bisecting and give SDL devs some time and instead patch my client launcher to use .14 ? :D

depends on how many ppl use a similar setup as you i guess

09:02

i have no problems with .17

oh cmn mine is really mainstream

09:02

nvidia best gfx card, arch best linux, gnome best DE, xorg best wm

nvidia sucks

e.g. nvidia not open source, and not mesa

amd better on linux

maybe not every dude on planet plays teeworlds

09:03

yes ryo u right

09:03

i also hate nvidia

09:03

but they make strong cards

xorg is not a wm

09:03

wm = window manager

its a popular choice wouldnt u say?

xorg is a window system display server

ah ye wat was it a window server?

09:03

yas

intel arc is best

i would argue that nvidia are the most used gfx cards

they are

but on linux its best amd

amd is always a few percent behind

ye thats my point i have a mainstream setup

atleast for drivers

amd integrates better

09:04

just like intel tbf

nvidia doesnt want their drivers open source

they both have mesa opengl drivers

my next rig will probably be amd i guess

also remember https://www.youtube.com/watch?v=iYWzMvlj2RQ

Linus Torvalds: Nvidia, Fuck You!

or intel arc xddd

such a meme

09:05

seen it so many times :D

09:06

amd sometimes faster than nvidia pretty nice, but sometimes also insanly slow xd

are 6000 series rdna2 or smth like that?

yeah

i wanna buy 6700 xt

09:08

but prices too high

yeah dude no chance xd

09:09

rly sdl...

main

i dont wanna be racist or anything...

09:09

but main

xdd

i dont even get whats wrong with it

09:10

its the MAIN branch

09:10

thats the most logical word

main is racist to secondary people

https://www.youtube.com/watch?v=9Q3_1xWXuAY

Not to be racist but asian people YAAA!

09:10

someone should edit that meme to "main branch"

i think we should also rename ddnet master branch to main

09:11

or default

yeah a lot of companies update their wording

09:11

I think blacklist is also changed

monkalaugh

which also makes sense imo xd

i rq the gfx repo because it has main branch

just always use the best fitting word

blacklist fits best

Why change the word when there is nothing broken about it?

in germany we litteraly say "red list"

i also like the word main and i see that master and slave is kinda fucked up :D but i grew up typing "git checkout master" and now half of the projects use this and half of the projects use this

context matters

if every project on da planet would switch to main i would get used to it at some point for sure

im a master of my craft

I don't get breaking peoples muscle memory built up over years because some people don't understand context

people who mastered something are racists now

think of all the git newcomers who see stack overflow using master branch omagawd

well

yas

its not about that tho ryo

09:13

you master yourself

09:13

thats different to master someone else

master the poor branch

???

when rename master boot record to main boot record?

You can either argue that there is context to words and their meanings adapt accordingly or they don't. You can't argue both

you master a skill

ur implying a branch which is some bits has some kind of humanity

????

yas

dude

stop branch shaming now!

i litteraly said choose most fitting word

master

main branch makes more sense

xxxxxxxD

09:15

main is also shorter

09:15

i agree main is nice

09:15

but change is bad

09:15

also 0.7 makes more sense than 0.6 @Deleted User :p

Deleted User

main branch makes more sense

Why? The word master has arguably acquired the correct meaning over the century we've used it whether in photography or recording

bcs a branch isnt a master

09:17

its more like a place

09:17

the main place

Master and main convey the exact same meaning to me in the context of git branches

omagawd learath dont compare ur english skills with the average joe. You would also say novice instead of easy. Our vocab is simple

your capital isnt the master city

nobo

main city would fit tho

09:18

it also translate like that to germany

A master is something you make copies out of. You don't clone your capital to make new cities

yo learath u made the sdl version so verbose right?[2021-08-17 11:24:51][sdl]: SDL version 2.0.15 (compiled = 2.0.16)veri helpful

bit weird because the compiled file claims to be .14.1 but yeee i assume sdl2 devs were drunkcp build/.libs/libSDL2-2.0.so.0.14.1 ~/Desktop/git/ddnet/build/libSDL2-2.0.so.0

chillerdragon: make issue on matrix bridge then, if you dont do it on SDL, use your energy xd

chillerdargon how is ur user a bot? :O

we train the AI chillerdragon

sus

jupsti i make sdl issue

whats wrong with sdl, chiller?

sdl broke fullscreen

@¡deadboo! but srsly, they use matrix, the new fancy way of chatting

fakin sdl devs

09:32

timakro: they added 1 sec of blackscreen when tabbing between two fullscreen ddnet clients

You're invited to talk on Matrix

You're invited to talk on Matrix

09:32

i cant do hammerhit anymoire :/(

09:32

matrix sucks

r u tabbing between two fullscreen ddnet clients instead of using the dummy feature?

Omg my system froze

09:33

Send help I can’t do anything anymore

09:33

SDL crashed my compooter wtf

09:33

I hope git bisect works across System reboots

09:33

@timakro I use 4 dummy’s so …

09:34

Would you say crashing my computer is git bisect good or git bisect bad? I mean idk if it has the black screen issue

I hope for you that most commits compile

git bisect is a state so should work

If it really crashed your computer it would be a git bisect skip

happened a few times already that i forgot to disable bisect xD

ah thats a thing

09:35

ok lemme try again

09:35

wish me luck

09:36

wat was pgk conf var name again

09:36

i should really get a shell history manager

http://progressquest.com/play/

09:36

wtf

09:36

hit play lmao

tmux always sowllws it

PKG_CONFIG_PATH

09:36

history | grep PKG?

ty babe

09:36

ctrl+r DDNET

09:36

but no

09:36

history file is only one

09:37

when having multiple shell sessions its not always veri good

09:37

hmm now it didnt crash

09:37

ok

yeah this sucks why is noone solving this

09:37

with the history file

because ur not supposed to use more than one shell :D

09:38

use ctrl+z and fg instead

i guess the session which ends last overwrites the file?

yas something like that

09:38

im sure there is a tmux plugin for that or a whatever thung

09:38

never was moitivated to search it

09:38

oh right i forgot about ctrö+z last time

09:38

timakro thats good command to

09:39

vim foo.c (ctrl+z make; fg)

ah ye

09:39

never used this

09:39

but seen this before

same

09:39

i got multiple shells :D

09:40

but still maybe sometimes u dont

i use ctrl z a lot

ur a weirdo

i open them like browser tabs

09:47

ctrl+a and ctrl+e obviously stand for "anfang" "ende"

ja

09:53

one of the many reasons why tmux is better than screen is that screen fakin hijacks the ctrl+a

how to exit screen? :D

axaxax

when are we upgrading cmakelists.txt to some configure shellscript? :)

10:00

inst windows counting as POSIX unix nowerdays anyways?

10:01

they ship openSSH and linux kernel im sure they can also run a ./configure

mmm

better not xd

hihi

10:07

i think i never saw any configure script that passed shellcheck :D

you use the configure script?

for sdl?

10:09

there is a non configure way?

y

o.O

cmakelists

INSTALL.md told me so

i always hate repos that dont have cmakelists

nah

10:09

configure is cool!

dunno what GNUs idea behind this build tools ever was

almost as cool as bam

but way too complicated for my brain xd

u dont gotta no aint read it

10:10

just run and feel hacker

xd

im always afraid to run make with more than one thread in projects i dont know

10:12

i was debugging some build error i forgot which project maybe handbreak for hours and turned out they didnt support parralel building :D

do anyone know how to make skin help

Frequency illusion

Frequency illusion, also known as the Baader–Meinhof phenomenon or frequency bias, is a cognitive bias in which, after noticing something for the first time, there is a tendency to notice it more often, leading someone to believe that it has a high frequency (a form of selection bias). It occurs when increased awareness of something creates the ...

watafak i was suprised all the .14 versions showed up as .16 and the bisect was bad 4 times in a row now i tested again and seems like its using my /usr/lib sdl again

11:47

@Deleted User: is that wrong?PKG_CONFIG_PATH="$(pwd)" ./DDNet

u need to use LD_LIBRARY_PATH

aaaaaaaaaa

PKG config might work with building

lets start bisect again...

11:53

how do i exit bisect :D

11:53

vim2.0

bisect stop or smth

its reset

11:54

but doesnt work with dirty working tree

11:54

it gets dirty on build tho so annoying

i rly miss a headless matrix client

gnome froze again :D

13:01

adding a fakin const shouldnt add 1 sec of blackscreen should it?

13:02

unless non const has some unknown performance boost nobody knows off :D

just go a few commits before that to check if its working again and then few commits after and check if its really broken

i did

14:19

and its not true

and found it chillerdragon?

no

15:15

constant system crashes are kinda time consuming

15:15

plenty of build errors

but i guess you are close?

no

15:16

i feel like i drift fruther and fruther

oh thought u have 14 steps with bisect

9

15:17

either i arrive at a invalid commit

in worst case report it without the commit, they might know what the problem is

or at the end of bisect where its stuck

15:17

its just day 1 debugging this

15:17

:D

15:18

i might be slow and sloppy but i am not giving up yet

thats the spirit

What bug are you looking for?

i feel like even bad SDL code shouldnt be able to crash my Xserver all the time omagawd

15:20

i get 1 sec blackscreen when i tab out of fullscreen

15:20

it used to be instant and i really need it instant

Bad xlib calls usually dont crash, is your system stable? :P

15:22

that gives a big ass blackscreen until window server is reloaded

15:22

go debug xorg next? :D

15:23

wow my second ACCDIDENTAL pc reboot today that must be a record

f window server

15:24

aaaaaaaaaa

its hilarious since that error message could normally not be seen because when it pops out in the terminal the window server is dead already and when rebooting it the terminal session is gone :D

15:31

... unless tmux

15:31

im sure debugging xorg must be a fun thing

hi devs 8) so when you say /times Name it lists when Name finished, and with what time. But you can't figure out with who, like what the whole team was. could that feature be added ?

test

i feel like the window bug was introduced somehwere during that 100 crashing commits but i can not tell. So maybe i gotta bisect the crash and apply the patch during the bisect of the other bug

xd

15:53

green dragons better than red dragons tho

zoozuki

suzoozki

ok fuck bisect tomorrow i will go back 1 commit by one manually

Are you bisecting sdl?

if arch packages werent so outdated i would have known immediatly maybe i should run SDL2-git from now on

16:10

yas since 8 hours

Try version by version maybe? That should help narrow down further

16:10

Then you can look at the commit list and figure out which are related

troll

16:11

.14 is ok

16:11

.16 is broken

16:11

.17 is broken in another way

16:11

.15 does not exist

16:11

half of the commits between .14 and .16 crash my xserver

16:11

so im kinda fucked

test

uuuhhh

19:45

i see many checks on CCharacter -> Team() != TEAM_SUPER and checks on with VANILLA_TEAM_SUPER

19:46

is there any difference?

19:46

like when we should use this and this

19:48

or we should check m_IsDDrace16 everywhere and choose right constant?

yo a short question, is there any option to activate/look into debug/crash log of tw?

run it with a debugger

19:49

which os are u on @FreZZ7 ?

how do i run debugger?

depends on ur os

win

run it in visual studio

Compiling teeworlds 0.7 windows (Visual Studio)

well... simply u can run executable in command line and when it will shut off u will have logs

imagine 0.7

but not crash logs

Anime.pdf

well... simply u can run executable in command line and when it will shut off u will have logs

oh nice how do i do it?

its same process in 0.6

gerdoe

or we should check m_IsDDrace16 everywhere and choose right constant?

this thing is important in some case if we still support ddrace16

FreZZ7

oh nice how do i do it?

wath da video

doesnt ddnet boot with a console by default

wawtch*

19:51

watch**

@FreZZ7: try running ddnet from the commandline

FreZZ7

oh nice how do i do it?

look for cmd in ur windows search and with command cd select a path cd C:/TeeworldsOrSmth and run it DDnet.exe

yeah i see, im not that much into programming, but thanks. i hoped for an easier way then compiling

Anime.pdf

look for cmd in ur windows search and with command cd select a path cd C:/TeeworldsOrSmth and run it DDnet.exe

yes nice thanks!

depends on the issue

compiling ddnet easier than making breakfast

if its an assert it shows in the normal logs

gerdoe

compiling ddnet easier than making breakfast

monkalaugh

why do you need it @FreZZ7 ?

seeing crashing error for a new map...

send me the map

19:53

i can do it for you

19:54

or better the server hosting it then its even less effort

chillerdragon

send me the map

i would but the creator doenst want to

19:54

but thanks for the effort

lol

FreZZ7

i would but the creator doenst want to

u can open editor in game and click File -> Load current map -> Save

why do you care for a crashing client if the map can not be played anyways

or go to /downloadedmaps and search for it

chillerdragon

why do you care for a crashing client if the map can not be played anyways

the map is making clients crash, so before it will be realeased we want to fix this?

makes no sense to me

?

you are not willing to create a crash report ur self and u do not allow others to do it :D

19:57

this way it wont be fixed

chillerdragon

you are not willing to create a crash report ur self and u do not allow others to do it :D

? i just ran ddnet into command line, i thought that will give me a error code...- its not my map, its the map of a friend of mine. so its not my decision. i just want to help him and i assumend i can do it without compiling

19:58

dont get me wrong, thanks for youre help/effort!

i am really confused and curious tbh

19:58

is the map for the public or is it a private secret map?

19:59

what client was used to create it?

19:59

what server does it run on?

chillerdragon

i am really confused and curious tbh

so a friend is creating a new map. the few ppl who looked into it have tw crashing several times on loading. i was like hey, tw must have something like an error log, let me find it and we should be easy to find a fix..., thats all

ok

kek

1

private map, ddnet client, trashmap

weird

actually you have this map

20:00

but nvm

gerdoe

actually you have this map

what do you mean?

chillerdragon

weird

what's wierd on that?

gerdoe

or go to /downloadedmaps and search for it

.

20:01

chiller are you on matrix bridge?

yes

does it show replies?

weird that it is crashing imo

20:01

no

chillerdragon

weird that it is crashing imo

yeah super wierd. it just closes tw without anything when loading the map. but completly randomly. not always just sometimes

gerdoe

compiling ddnet easier than making breakfast

Jerk. for some ppl this stuff (complainling) looks so freaking confusing/difficult^^

I think ath has crashlogs

20:05

I saw some trace collector in their code

chillerdragon

I think ath has crashlogs

idk, there willl be a day i will realy look into programming and get used with compiling and stuff, but not today

maps can easily crash clients, that is sadly not an easy fix

20:08

the smallest one I managed is 48 bytes in size

FreZZ7

Jerk. for some ppl this stuff (complainling) looks so freaking confusing/difficult^^

there actually few steps: download any vs studio 20xx download cmake gui download ddnet sources install vs studio choose everything for cpp if not chosen enter folder with ddnet sources open cmake gui with it write {your_path}/build in second placeholder run generate open project rmb on DDNet choose debug

i know, thtas why i dont do it now xd

Patiga

the smallest one I managed is 48 bytes in size

server can send weird maps too i guess? imagine 0 byte map xd

yes, the server can easily send any map, the error checking is very low-effort

FreZZ7

i know, thtas why i dont do it now xd

10-15 minutes are out, you could do it if you weren't such lazy ass xd

20:10

is there an issue for it?

not sure, but you would need to rewrite a large portion of the loading process, which itself is different for editor and client/server

gerdoe

10-15 minutes are out, you could do it if you weren't such lazy ass xd

10MBIT connection maybe?

ok? you could also send us map

gerdoe

ok? you could also send us map

yeah i would, but its not mine and i dont have permission

20:13

still thanks for the help, i still learned sommething

then no sense to help you bruh

20:14

okey have a nice night

gerdoe

then no sense to help you bruh

well i hope for an easier/faster way then compiling, thats all- sorry to have bothered you... i wanst expecting there isnt a debug feture already inside of tw...

hm ye error handling in tw is meh currently

20:15

only debugging by hands

hm lol why ddnet doesn't have switch unfreeze

20:30

cool feature

bruuuh why CCharacterCore has bools instead of bitflags

usability is better

memory footprint is worse, but performance is better?

we could iterate for DISABLE_HIT* flags and use less code

21:24

but usability is better xd
