@nori afferim sana!

Bug

Image attachment

But it could be finish without team

Isn’t

01:58

Ingame it’s 46 Teamrank, only bugging on website

what does ed_showkeys do (edited)

02:09

and is there any way to show my own key presses

@louis yo do u kno if u can record dummy movements and have it be execute ?

05:36

executed ?

nvm found it

wtf repeat bot

@Brokecdx- where did you see it ingame with 46?

@deen your laptop from 2009, what gpu does it have? XD

@Deleted User it's a thinkpad x200s. I got a second one though, by coincidence my girlfriend is still using the same laptop as me

So I can also test Windows now

08:31

Intel Graphics Media Accelerator X4500MHD

appearently opengl 2.1, would be nice

08:35

i added alot of fallback now, so even if you set the gfx_opengl_major to 4, it should atomatically detect that you are only on 2.1

[ddnet/ddnet] Pull request opened: #2627 Fix GUI Icons for OpenGL <= 1.5 (fixes #2619)

by making the image size a multiple of 2. Thanks to Jupeyy for analyzing and suggesting the fix.

So I should test the PR you sent? What exactly do I need to do

well first of all check if it works at all

08:36

and if it works at all we can test the fallback system

08:37

if that works too we could increase to opengl 3.0, so ppl have texture arrays, since most ppl have newer GPUs anyway

08:38

it should also be a bit faster , not alot but i added tile buffering, but not tile extension(like go out of map)

@Brokecdx- I fixed it now. These problems really shouldn't be happening... Zwelf: Not sure if there is something still wrong

08:42

The log file was missing already

@Deleted User can we use opengl 4 too as well? i saw u added some commits about opengl 4

u can use any opengl version then

08:52

but opengl 3.3+ is always the same

08:52

i didnt add opengl 4.5 specfic things yet

:D

Image attachment

@deen yes idk, it only happening to RUS i think? When i finish with rockus everything is fine on GER

@deen same for gui_buttons.png btw

does anyone have CMakeLists.txt for vanilla 0.6?

@Deleted User so I tried on Windows. The original DDNet client loads, shows text, but no graphics (all white boxes). Yours shows the colorful thing in the start, no text, and then crashes

09:16

@Deleted User done for gui_buttons

ok if not even the original ddnet client works, then rip xD

09:20

the new client should show the opengl version string in the console and maybe GLSL errors @deen

09:21

but thats the problem with opengl in general, it lacks support under windows before opengl 4.0 basically

Btw is it really necessary supporting under opengl 2? opengl 2 released on 2004, under versions are very old

well. imo anything older than 10years isn't really worth it, but we indeed have quite a few ppl here using opengl 1.4

@Deleted User It wasn't the SDL2 upgrade that broke it btw, DDNet 10 still worked, but lagged quite hard (as did DDNet 9)

09:24

maybe the Windows driver just sucks for OpenGL, on Linux I still use the same laptop just fine with multiple ddnet clients

yeah, linux is much better with opengl

09:24

ok, well @deen you can ofc try gfx_opengl_major 1; gfx_opengl_minor 4; it will disable the mipmap generation

09:25

i cannot really think of anything else that changed in the older GL backend

09:25

and text for example does not use mipmap generation

09:26

and white textures are basically always an indicator for broken texture completness(so mipmapping, or sampler config)

on Linux it works fine, fallback from opengl 4 -> 3.3 -> ... -> 2.0 works fine too

OK at least some good news xd

3e42eac Update funding status - def-

i'm in sunny side up like 5 mins and my rank just doesn't load, /rank won't answer as well

@nori can happen sometimes if the server get a dos attack (at least from what I know from kog server).

after 6 mins it's loaded but still rank commands won't answer

10:10

hm strange

(not 100% sure with my answer, I'm not into coding or anything. Just my guess)

@nori i know what the problem is and it will be fixed soon. The problem is just that the servers aren't going empty so we can't restart them

oh okay

@nori i found a quick fix, works now?

yes

@Learath2 I used your iptables nat and it works ok once the connection failed once, better than nothing

[ddnet-web:master] 1 new commit

b9e95fe Forgot Korea - def-

Don't forget to enable ip forwarding

done

@deen maybe we could force the connection to fail somehow

@nori fixing your bug caused another bug, ddnet servers were not showing up in internet tab. Oops...

justatest

I'm getting "No master servers" on Korea and CHN(1). Weird

14:46

@heinrich5991 @Learath2 any experiences with this? ^

14:46

There are no iptables rules, so I'm not sure

[ddnet/ddnet] Issue opened: #2628 sv_use_sql 0 still uses sv_sql_failure_file

Noticed by Lwai on Discord, caused him to have a map finish from test server before the map was even released.

regsixup works correctly, but register doesn't

[ddnet/ddnet] Pull request opened: #2629 Clarify sv_use_sql config description

Helps with #2628

tcpdump confirms that the master servers are not responding to us (0.6 only), while 0.7 replies

did they close the servers?

15:33

for 0.6

no, running

15:37

just these 2 servers can't register

@Deleted User gfx_opengl_major 1; gfx_opengl_minor 4 works better, but still a few white boxes left

15:54

better even than the current ddnet release

Zwelf: Does it help to reduce the number of sql servers? Will that make things simpler to have just 1 write server globally and file fallback?

with embedded texture in the maps there will always be some white textures =\

@redix i'm not familiar with our graphics, why?

because mappers dont check if they are power of 2

and it's not just in the map, also the heart and lock symbol in server browser

well they can be fixed but you cannot fix all maps

I went through all DDNet maps and made the tile maps powers of 2

quads?

didn't know it should also be done for quad graphics

everything in the game i think

the reason I did it was so we can easier convert maps to TW0.7 since the maps there have this limitation for tile layer graphics

16:11

Can't we scale it in memory and then use that as a fallback?

sure but i dont think there is a suitable scaling algorithm in the code right now

16:16

well the is a Rescale function in the backend. should probably be enough

[ddnet/ddnet] Issue opened: #2630 Use Rescale function in the backend to convert image sizes to powers of 2

For compatibility with old GPUs. As discussed with redix on Discord. @Jupeyy thoughts?

Yeah thought about that to, but only want this in gl1 context tbh.. Now I can easily apply patches like that

d22690c Add new player record - def-

@deen: yes would make the sql writing/updating less error prone. E.g. the /save corner cases when reading from the same ddnet server (e.g. GER2), but different MySQL server.

@heinrich5991 @Learath2 let's get rid of the db replication and run only one?

can all servers reliably reach one other server?

18:51

especially china?

^

well, would be nicer to have fallbacks, but the replication has also been causing a few problems

18:53

we can then also get rid of the country in save

@deen you can try the new commit

19:19

it will hopefully fallback to opengl 1.5 now with a clean config and will resize images that arent power of two (edited)

[ddnet/ddnet] Pull request closed: #2629 Clarify sv_use_sql config description

@Deleted User if(GLEW_ARB_texture_non_power_of_two || pCommand->m_GlewMajor > 2) shouldn't it be >= 2? i think opengl 2 requires support for non power of 2 textures, but does not necessarily list ARB_texture_non_power_of_two

you are absolutly right but look here: https://www.khronos.org/opengl/wiki/NPOT_Texture "older hardware"

19:51

seems like they just didnt care and said opengl 2.0 is supported

okay...

the chance that the driver is buggy if it doesnt list that extension is higher than that it isnt listed and 2.0 is supported xD

19:51

atleast i guess so

yeah probably

@deen I think we should have atleast one server mirroring so we don't lose all our data in a catastrophe

deen takes daily backups AFAIK

20:54

much better server admin than I am

im not sure if this was intended, but like when u save a run and load it u cant do /r if u go in practice mode, it will just be the location where u fell in freeze but not the previous location where you were unfrozen

@Learath2 I have daily backups of the full server and the database, but only keep them 3 days back actually.

5e069a4 Fix ddnet-libs version to master - def-

Anyone here who is good with iptables? Somehow I fail to even do a simple rate-limit on udp on specific packets... (not by ip)

Embedded image

23:04

updated the client, rip now

23:04

help

@deen

sudo iptables -t mangle -A PREROUTING -p udp -s 1.2.3.4 -j newchain
sudo iptables -t mangle -N newchain
sudo iptables -t mangle -A newchain -p udp -m limit --limit 50/s --limit-burst 100 -j ACCEPT
sudo iptables -t mangle -A newchain -p udp -j DROP

except instead of -s 1.2.3.4 u choose whatever way u wanna match packets?

@Virus2k help with what

you started ddnet-server instead ddnet client (edited)

i see i see

23:14

thought its the "new" exe

23:15

since i dont have one anymore after the update

23:15

it just killed my whole client somehow

23:15

can someone give me the starting exe?

just download it again

wew

23:18

just give exe

does anyone know why my server has "trouble" with 0.6 masters? i mean, it works, it registeres, but these messages are quite spammy...

Image attachment

@noby @deen instead of -j ACCEPT there's also a suggestion to use -j RETURN, which will just exit the created chain and continue to check with the next rules
