02:12 <+bridge> [ddnet] <fokkonaut> @Learath2 can it be that extended net messages differ in their uuid?
02:12 <+bridge> [ddnet] <fokkonaut> because i cant seem to send a ddnet client the capabilities msg
02:12 <+bridge> [ddnet] <fokkonaut> and i cant seem to receive the show distance msg from a ddnet client
02:12 <+bridge> [ddnet] <fokkonaut> (it worked before, i dunno why i cant receive it)
02:33 <+bridge> [ddnet] <fokkonaut> i am out of ideas, for real :D
02:52 <+bridge> [ddnet] <Learath2> ofc not
02:52 <+bridge> [ddnet] <Learath2> the uuids stay the same
02:59 <+bridge> [ddnet] <fokkonaut> ye i mean
02:59 <+bridge> [ddnet] <fokkonaut> idk xd
03:19 <+bridge> [ddnet] <Learath2> debug what exactly you receive on the client when you send it e.g. capabilities
03:19 <+bridge> [ddnet] <Learath2> I'd print a hex dump dbg_msg
07:15 <+bridge> [ddnet] <Дядя Женя> Why won't you just send ddnet version as one number, so check if it's greater then X, then it supports something
08:00 <+bridge> [ddnet] <heinrich5991> @Дядя Женя because we want to support other mods
08:01 <+bridge> [ddnet] <Дядя Женя> What do you mean by mods
08:01 <+bridge> [ddnet] <heinrich5991> modifications
10:03 <+bridge> [ddnet] <deen> Anyone here got an idea how people rename themselves from one name to the same? They trigger the message `'$name' changed name to '$name'`. This is printed in gamecontext.cpp:2183 if WouldClientNameChange returns true. That function returns `str_comp(m_aClients[ClientID].m_aName, aNameTry) != 0`. So I'm confused. The names are printed exactly the same in logs (verified with hexdump), not just similar.
10:07 <+bridge> [ddnet] <Jupstar ✪> but it also returns true somewhere else doesnt it
10:08 <+bridge> [ddnet] <deen> No
10:08 <+bridge> [ddnet] <deen> only if the `Set` parameter is true, which it isn't for WouldClientNameChange
10:08 <+bridge> [ddnet] <Jupstar ✪> i see the opposite
10:09 <+bridge> [ddnet] <Jupstar ✪> or better
10:09 <+bridge> [ddnet] <Jupstar ✪> i see it true when setclientname is set
10:09 <+bridge> [ddnet] <deen> what is setclientname?
10:10 <+bridge> [ddnet] <Jupstar ✪> a function that is called by the gamecontext on player mconnect mesage
10:10 <+bridge> [ddnet] <deen> But we only call that when WouldClientNameChange was true
10:11 <+bridge> [ddnet] <Jupstar ✪> not when NETMSGTYPE_CL_STARTINFO is set
10:11 <+bridge> [ddnet] <deen> ehm, we don't check that startinfo has been set already?
10:11 <+bridge> [ddnet] <Jupstar ✪> so you can only change the name by this packet?
10:12 <+bridge> [ddnet] <deen> ah, we do. first line is `if(pPlayer->m_IsReady) return;`
10:12 <+bridge> [ddnet] <Jupstar ✪> but maybe the name was set before
10:12 <+bridge> [ddnet] <Jupstar ✪> or is that impossible?
10:12 <+bridge> [ddnet] <Jupstar ✪> NETMSGTYPE_CL_CHANGEINFO does not check for ready
10:13 <+bridge> [ddnet] <Jupstar ✪> but i also not 100% into this whole code
10:14 <+bridge> [ddnet] <deen> could they keep renaming? I don't get it
10:14 <+bridge> [ddnet] <Jupstar ✪> maybe they have some bot client that changes skins or smth like that and spam the info directly
10:15 <+bridge> [ddnet] <Jupstar ✪> idk
10:15 <+bridge> [ddnet] <Jupstar ✪> as said i dunno how sensitive the server is with packets, bcs im not too much into it
10:15 <+bridge> [ddnet] <Jupstar ✪> but thats something i could imagine xd
10:24 <+bridge> [ddnet] <Jupstar ✪> the server doesnt care about NETMSGTYPE_CL_STARTINFO
10:25 <+bridge> [ddnet] <Jupstar ✪> if(m_aClients[ClientID].m_State == CClient::STATE_READY)
10:25 <+bridge> [ddnet] <Jupstar ✪> is outside of the return true
10:25 <+bridge> [ddnet] <Jupstar ✪> so i guess this is possible
10:39 <+bridge> [ddnet] <Jupstar ✪> ok it does check it indeed
10:47 <+ChillerDragon> @deen you mean the 'nameless tee' -> 'nameless tee' log messages right? Spammed all over the place by a few tees. As far as i remember those are usually clan or skin change binds bound to a and d for example
10:53 <+bridge> [ddnet] <deen> ChillerDragon: Yes, but why would a clan/skin change show up?
10:54 <+bridge> [ddnet] <deen> I can't reproduce it or understasnd how
10:56 <+bridge> [ddnet] <Jupstar ✪> yeah me neither now xd
10:57 <+bridge> [ddnet] <deen> Would be much easier if our professional pentesters also reported how they did their cheats
11:12 <+ChillerDragon> haha the front :D
11:14 <+ChillerDragon> hm i can also no longer reproduce it but i remember seeing my clan bind in my logs at some point
11:15 <+ChillerDragon> I really would love to see a nice pdf by pink rat documenting ddnet map skips :D
11:18 <+bridge> [ddnet] <deen> ok, got it
11:22 <+bridge> [ddnet] <murpi> just wow
11:31 <+bridge> [ddnet] <deen> I'd like to deploy 3426 quickly. Someone got time to review?
11:56 <+bridge> [freenode] <Zwelf> Okay, I've taken a look.
11:56 <+bridge> [ddnet] <deen> thanks
12:39 <+bridge> [ddnet] <Roco> @deen here???
12:47 <+bridge> [ddnet] <deen> @Roco sometimes
12:49 <+bridge> [ddnet] <Learath2> @deen apparently their server broke while hosting a tournament, he was asking whether we could host gctf for them again
12:54 <+bridge> [ddnet] <ᶰ°Konͧsti> :feelsbadman:
14:10 <+bridge> [ddnet] <Roco> guys can any1 help out with servers? we need 4 servers, else we will cancel the tournament
14:39 <+bridge> [ddnet] <Дядя Женя> ping deen
15:13 <+bridge> [ddnet] <Learath2> I got it set up, was going to do it but I didn't have access on the computer I was on
16:44 <+ChillerDragon> @Roco sure i can help w servers
16:47 <+bridge> [ddnet] <heinrich5991> Learath2 already did
16:48 <+ChillerDragon> oh
18:50 <+bridge> [ddnet] <deen> Sorry, I wasn't home
19:30 <+bridge> [ddnet] <deen> The format of today's AoC looked 100% like a DCG, so I just used sed+prolog to run it: https://github.com/def-/adventofcode-2020/blob/master/day19.pl
19:35 <+bridge> [ddnet] <Ryozuki> whats this magick
19:36 <+bridge> [ddnet] <deen> https://www.metalevel.at/prolog/dcg
19:36 <+bridge> [ddnet] <deen> an easy way to define a grammar in prolog. You could do it without that, but it's a bit more syntax
19:36 <+bridge> [ddnet] <Ryozuki> 😯
19:38 <+bridge> [ddnet] <deen> Maybe I should consider this my sed-solution 😄
19:39 <+bridge> [ddnet] <Jupstar ✪> if u want a challenge program it for a GPU
19:40 <+bridge> [ddnet] <deen> I think this explains it better actually: https://en.wikipedia.org/wiki/Prolog_syntax_and_semantics#Definite_clause_grammars
19:40 <+bridge> [ddnet] <deen> I don't, I've gotten lazy and am searching for the easiest solutions now 😄
19:41 <+bridge> [ddnet] <Ryozuki> i also got lazy :pepeH:
19:41 <+bridge> [ddnet] <deen> I have some multiprocessing languages on my list, but felt like it's too stupid to split up these small problems into chunks
21:48 <+bridge> [ddnet] <timakro> I actually had this grammar stuff in first semester.. too bad I already forgot everything
21:49 <+bridge> [ddnet] <timakro> But I still remember the name of the algorithm
21:49 <+bridge> [ddnet] <timakro> It's called CYK
21:50 <+bridge> [ddnet] <timakro> We had to do the algorithm by hand in table from for the exam
