14:24 <+bridge> [ddnet] @TsFreddie is that on fullscreen or what? 14:25 <+bridge> [ddnet] Fullscreen on 14:25 <+bridge> [ddnet] toggle fullscreen off and on then I got the second screenshot 14:26 <+bridge> [ddnet] ok bcs we actually update the viewport in fullscreen and learath said in mac the canvas size is not equal to window size 14:26 <+bridge> [ddnet] so i could atleast try to patch that 14:44 <+bridge> [ddnet] @TsFreddie can u compile on that laptop?

15:03 <+bridge> [ddnet] In CClient::LoadMap in client.cpp you could probably remove the hash-checking code 15:03 <+bridge> [ddnet] and then you need to recompile the client 15:20 <+bridge> [ddnet] sneaky peaky, how he just evaded my requested changes by opening the same pr few months later 15:22 <+bridge> [ddnet] oooh 15:22 <+bridge> [ddnet] sorry, didn't remember that you had requests on the original change 15:26 <+bridge> [ddnet] @Jupstar ✪ 15:26 <+bridge> [ddnet] https://cdn.discordapp.com/attachments/293493549758939136/788411736839290950/unknown.png 15:26 <+bridge> [ddnet] oof 15:26 <+bridge> [ddnet] sleep time, maybe next time 15:28 <+bridge> [ddnet] mhh looks annoying xD 15:35 <+bridge> [ddnet] well also doesnt matter probs @deen 15:35 <+bridge> [ddnet] the initialization works bcs in tw everything is static, as soon as we wouldn't do that the zero initlaization would drop and it would require a proper constructor 15:35 <+bridge> [ddnet] 15:35 <+bridge> [ddnet] Aslong you read the pr for possible null ptrs its fine 15:35 <+bridge> [ddnet] and aslong its consistent and doesnt break after some time xD 15:47 <+bridge> [ddnet] I can't build on macOS again... 15:47 <+bridge> [ddnet] This is really driving me insane 15:47 <+bridge> [ddnet] :cirBlech: 15:48 <+bridge> [ddnet] If I get Command Line Tools I can't compile ddnet 15:48 <+bridge> [ddnet] i can't figure out why vscode isn't stopping at breakpoint 15:48 <+bridge> [ddnet] if I don't get command line tools brew can't compile python 15:52 <+bridge> [ddnet] This is all soooooo annoying, why do people like to work like this?

CMake is using the clang inside xcode, my developer directory is correctly set to the dev dir in xcode. Yet this clang is using the commandlinetools version of includes 15:54 <+bridge> [ddnet] Do I go digging into clangs source code? 16:02 <+bridge> [ddnet] Okay figured out it's cmake breaking, now what I dig into cmake? 16:06 <+bridge> [ddnet] have u used a clean cmake build dir 16:06 <+bridge> [ddnet] yes 16:08 <+bridge> [ddnet] has cmake no debug or verbose mode, maybe the path isnt set in the right order or smth 16:08 <+bridge> [ddnet] could we maybe get hook tiles on those platfoms here? 16:08 <+bridge> [ddnet] https://cdn.discordapp.com/attachments/293493549758939136/788422223778021396/screenshot_2020-12-15_16-07-08.png 16:08 <+bridge> [ddnet] i see a lot of people blocking 16:08 <+bridge> [ddnet] on multeasymap 16:08 <+bridge> [ddnet] and i think that adding hook tiles on the floor would help people to defend 16:09 <+bridge> [ddnet] I narrowed it down to find_path finding a sqlite3.h inside commandlinetools, which is expected, but how it gets there I can't figure out at all 16:12 <+bridge> [ddnet] this is beside the point anyway, ofc I can debug it given an hour or two, I had an hour to spare and I wanted to look at the clipping issue @TsFreddie saw, now instead I'm wasting time wrestling with tools. Same experience on windows too 16:12 <+bridge> [ddnet] I never get to do any work, I only fix stupid tooling issues 16:12 <+bridge> [ddnet] @deen gonna create a quickpatch or a new version? 16:13 <+bridge> [ddnet] I bet this one is also going to boil down to some mistake in homebrew like every other macOS build issue I've had, because the person who made homebrew has a messiah complex and created a bloated mess 16:14 <+bridge> [ddnet] @Learath2 btw i tried to fix it: 16:14 <+bridge> [ddnet] https://github.com/Jupeyy/ddnet/tree/pr_macos_fix_try 16:14 <+bridge> [ddnet] u can download the artifact 16:14 <+bridge> [ddnet] and try if u want xd 16:14 <+bridge> [ddnet] I was surprised when I got the ddnet client building on windows in about an hour even though I never used visual studio before or compiled anything on windows 16:14 <+bridge> [ddnet] I'd just cherry-pick this one change? I'm not sure if we have other changes with high risk, but don't want to wait around for RCs 16:14 <+ChillerDragon> gj @timakro 16:14 <+bridge> [ddnet] ok 16:15 <+bridge> [ddnet] @timakro if u exclude the cmake process which downloads Gtest always on windows 16:15 <+bridge> [ddnet] then its strange 😄 16:15 <+ChillerDragon> well ok an hour is some time but it can also take an hour alone to dl bloat studio 16:15 <+bridge> [ddnet] maybe disabled multiprocessor on VS? 16:17 <+bridge> [ddnet] It seems like there are a lot of options on windows with a separate git tool on the git website and the WSL git. Same for cmake, the cmake for windows tool works with a lot of IDEs. You can kinda mix and match and even if you don't really know what you're doing the tools most of the time work together. You never quite understand how though. They must have put a lot of work into making those tools compatible 16:17 <+bridge> [ddnet] @timakro you know what works great? Ignoring the windows way of doing things. As soon as I ditched the pipe dream that I'd get to do something the "windows" way once, I got it working in a matter of minutes 16:18 <+bridge> [ddnet] Just get msys2, works perfectly. Or use cmd, nmake/ninja and the console version of cmake, works perfectly 16:18 <+bridge> [ddnet] Yep 16:19 <+bridge> [ddnet] I really hope this guy is onto something 16:20 <+bridge> [ddnet] :PES2_Depressed: windows 16:20 <+bridge> [ddnet] btw cmake has a lot of generators everywhere 16:20 <+bridge> [ddnet] I can generate sublime 3 projects, though no idea why anyone would want that 😛 16:21 <+bridge> [ddnet] Meh sublime 16:21 <+bridge> [ddnet] Why would anyone use that 16:21 <+bridge> [ddnet] Vscode ecosystem is bigger 16:21 <+bridge> [ddnet] But vim is bettee 16:21 <+bridge> [ddnet] :PES2_Depressed: 16:22 <+bridge> [ddnet] Anyway, seems I will have to strace cmake to figure out what it's doing with pkg_config 16:22 <+bridge> [ddnet] I'll go have fun with that 16:27 <+bridge> [ddnet] "ld: warning: dylib (/usr/local/lib/libpng16.dylib) was built for newer macOS version (10.15) than being linked (10.9)" 16:27 <+bridge> [ddnet] yeah now macos is onfire in the libpng pr too 16:28 <+bridge> [ddnet] Aaaaand ofc it's homebrew messing with things `Variable declaration, 'homebrew_sdkroot' has value '/Library/Developer/CommandLineTools/SDKs/MacOSX10.15.sdk'` 16:29 <+bridge> [ddnet] @Jupstar ✪ we either need to start shipping our own version of SDL or push SDL to finally fix the issue so we can start building for 10.15 16:30 <+bridge> [ddnet] (or we can build libpng too, we build our own curl and ffmpeg already) 16:32 <+bridge> [ddnet] i'd just ignore the system path comletly and dont do a prefer bundled, and then just static link everything 16:32 <+bridge> [ddnet] all problems solved for non linux OS 16:34 <+bridge> [ddnet] We do build our own libpng 16:34 <+bridge> [ddnet] yeah but not aggressivly enough xD 16:34 <+bridge> [ddnet] macos fails again 16:35 <+bridge> [ddnet] just rebased to the png_init commit 16:35 <+bridge> [ddnet] then just put some -DPREFER_BUNDLED_LIBS=ON in? 16:36 <+bridge> [ddnet] yeah maybe later, we also have to update the build scripts then etc. pp 16:37 <+bridge> [ddnet] @Learath2 yeah pls get SDL dev, and also fix the window focus under windows 16:39 <+bridge> [ddnet] I've completely lost all the motivation I had, I was going to fix a couple things today but I guess not 16:39 <+bridge> [ddnet] `/Library/Developer/CommandLineTools/usr/bin/../include/c++/v1/cmath:317:9: error: no member named 'signbit' in the global namespace` look at this, what am I supposed to do about that? 16:39 <+bridge> [ddnet] Do I have to become a compiler engineer too? 16:40 <+bridge> [ddnet] do u use some experimental libc++ ? XD 16:40 <+bridge> [ddnet] No it's just CommandLineTools as shipped by apple 16:41 <+bridge> [ddnet] wtf xD 16:41 <+bridge> [ddnet] how does apple or the clang team even do that on macos 16:41 <+bridge> [ddnet] i use experimental clang and had like no bug in 1 year xd 16:42 <+bridge> [ddnet] I remember I had the same error: https://stackoverflow.com/questions/58628377/catalina-c-using-cmath-headers-yield-error-no-member-named-signbit-in-th 16:42 <+bridge> [ddnet] :huh: 16:42 <+bridge> [ddnet] @deen Yeah we had it on CI, I "fixed" it by `rm -rf /Library/Developer/CommandLineTools` 16:43 <+bridge> [ddnet] XCode comes with a complete set of tools already and they aren't broken 16:43 <+bridge> [ddnet] ok 😄 16:45 <+bridge> [ddnet] :cirBlech: 16:45 <+ChillerDragon> there is no other os i know that goes so strong to push their own dev toolchain literally every macOS dev has xcode 16:46 <+bridge> [ddnet] Why ship 2 sets of tools even, why are these people like this? 16:46 <+ChillerDragon> 2 sets? 16:46 <+bridge> [ddnet] Whenever I'm doing something I try to minimise work. Just isolate the common "tools" into a package and have the IDE use those? 16:47 <+bridge> [ddnet] CommandLineTools and XCode come with two entirely different set of "tools" 16:47 <+ChillerDragon> woot i did not know 16:47 <+bridge> [ddnet] I finally isolated the issue 16:47 <+bridge> [ddnet] no idea how to fix it though xD 16:48 <+ChillerDragon> so when i go to the appstore and dl 4gb xcode i get another version of the tools shipped in ``xcode-select --install`` ? 16:48 <+bridge> [ddnet] cmake is adding a `-I/Library/Developer/CommandLineTools/SDKs/MacOSX10.15.sdk/usr/include` to the compiler line, no idea what adds it, don't have any way to debug it 16:48 <+bridge> [ddnet] i like my way of dealing with these things 16:49 <+bridge> [ddnet] ChillerDragon yes 16:49 <+bridge> [ddnet] it's called giving up 16:49 <+ChillerDragon> hm 16:49 <+ChillerDragon> i thougth they depend on each other 16:49 <+ChillerDragon> i remember ``xcode-select --install`` caused a update popup for xcode 16:49 <+bridge> [ddnet] I have 4 copies of clang on my computer: inside XCode, inside the CLT, one I built myself to test something and another from brew 16:50 <+ChillerDragon> macports masterrace 16:50 <+ChillerDragon> why would you build clang ur self 16:50 <+ChillerDragon> u nuts? 16:50 <+bridge> [ddnet] That's the only way to rule out Apples insanity 16:51 <+bridge> [ddnet] I accidentally created a file called `-c` how do I delete it? 16:51 <+bridge> [ddnet] rm -- -c 16:52 <+bridge> [ddnet] thanks, I thought \\-c would work but apparently not 😛 16:52 <+bridge> [ddnet] it's not an escaping problem, the shell doesn't do anything with -, the program itself does 16:52 <+bridge> [ddnet] and it's a convention to stop interpreting -args after -- 16:52 <+bridge> [ddnet] also important when you allow users to pass file names 16:53 <+bridge> [ddnet] and of course I know that because we have the maps -Ikarus-, -JustDoIt- & -SKY IVLAND- on DDNet 😄 16:54 <+bridge> [ddnet] Okay I can't fix this, the includedir for sqlite3, curl and zlib are all `/Library/Developer/CommandLineTools/SDKs/MacOSX10.15.sdk/usr/include` which is correct, but I can't have that passed as `-I` as includes that are part of the system are treated differently 16:55 <+bridge> [ddnet] For once I don't even have a vague clue what to do next 16:56 <+bridge> [ddnet] So I'll instead go sleep, what an absolute waste of time an entire hour and a half chasing a stupid issue because apple doesn't want to play nice with gnu 16:56 <+bridge> [ddnet] I'd honestly rather code on a limestone tablet 16:58 <+bridge> [ddnet] @Learath2 `-isystem`? 16:58 <+ChillerDragon> deen shell pro 16:58 <+bridge> [ddnet] Shell Pro Tip: Don't use shell scripts for anything public-facing 16:59 <+ChillerDragon> ima name my new ddnet map like a forkbomb ok? 17:00 <+bridge> [ddnet] call it "--no-preserve-root -rf /".map 17:00 <+ChillerDragon> xd 17:01 <+bridge> [ddnet] nah -isystem doesn't help either, nor could I possibly get cmake to use it anyway 17:02 <+bridge> [ddnet] hahaha `/Library/Developer/CommandLineTools/usr/bin/../include/c++/v1/stdlib.h:20:15: fatal error: 'stdlib.h' file not found` now I completely broke it 17:08 <+bridge> [ddnet] Oh I figured it out, finally 17:08 <+bridge> [ddnet] Still no idea how to fix it but for whatever reason cmake is using the macOS 11.0 sdk as the sysroot 17:09 <+bridge> [ddnet] So it's building with a very new clang, using a very old sdk, using the headers of a very new sdk 17:10 <+bridge> [ddnet] ``` 17:10 <+bridge> [ddnet] SQLite3_INCLUDEDIR:PATH=/Library/Developer/CommandLineTools/SDKs/MacOSX10.15.sdk/usr/include 17:10 <+bridge> [ddnet] SQLite3_INCLUDE_DIR:PATH=/Library/Developer/CommandLineTools/SDKs/MacOSX11.0.sdk/usr/include``` Here riddle me this one, what could be the possible reason for this? 17:11 <+bridge> [ddnet] @deen Isn't the skin database powered by shell scripts? 17:11 <+bridge> [ddnet] yes, but not the public-facing part 17:12 <+bridge> [ddnet] Did I write this? https://github.com/ddnet/ddnet-web/tree/master/www/skins/edit 17:12 <+bridge> [ddnet] only the moderator-facing part 17:12 <+bridge> [ddnet] That's comforting 17:12 <+bridge> [ddnet] I could have imagined past me hooking php up to shell scripts :D 17:13 <+bridge> [ddnet] I mean I hooked php up to python for trashmap 17:13 <+bridge> [ddnet] Ah it is accessible via web 17:13 <+bridge> [ddnet] You just need a login 17:13 <+bridge> [ddnet] I see 17:21 <+bridge> [ddnet] Think I found a bug in cmake 17:22 <+bridge> [ddnet] I was going to sleep, but noticed it's already 1700 17:27 <+bridge> [ddnet] Oh I actually should have went to sleep. I read 11.0 as 10.11 17:47 <+bridge> [ddnet] There is a simple application that wraps xcode so you can build for all apple platforms called `xcrun` 17:48 <+bridge> [ddnet] `xcrun` links to `libxcselect.dylib` which it immediately calls into and does nothing else 17:48 <+bridge> [ddnet] `libxcselect.dylib` upon this call loads another lib `libxcrun.dylib` dynamically and calls into that 17:49 <+bridge> [ddnet] which has many calls into `libxcselect.dylib` it's almost like italian bureucracy 18:04 <+bridge> [ddnet] heh, at the end of the chain, it execves an internal version of the binary xcrun 18:30 <+ChillerDragon> @timakro i like to call scripts using sudo from non admin user php code :D 18:33 <+bridge> [ddnet] ChillerDragon: you have set up sudo to only let through that particular command? 18:40 <+bridge> [ddnet] have you ever wondered about that dynamic libraries are quite bad concept? 18:40 <+bridge> [ddnet] i mean, dynamic libraries make sense in C, but in other languages, they are so awful to work with because maintaining ABI compatibility is hard 18:40 <+bridge> [ddnet] you usually end up with exporting plain C functions.... 18:44 <+bridge> [ddnet] something interesting to read: https://www.kix.in/2008/06/19/an-alternative-to-shared-libraries/ 18:44 <+bridge> [ddnet] hm. I like shared libraries 18:44 <+bridge> [ddnet] makes it easy to swap out stuff without recompiling everything 18:45 <+bridge> [ddnet] I found the oddest optimization I've seen in a decade easily 18:45 <+bridge> [ddnet] openssl security updates *cough* 18:45 <+bridge> [ddnet] This code is full of `strcmp(s, "f") && strcmp(s, "find")` 18:45 <+bridge> [ddnet] ehm, that doesn't sound like it's faster 18:46 <+bridge> [ddnet] does it do integer masks? 18:46 <+bridge> [ddnet] There is "r" "run", "n" "no-cache", "k" "kill-cache" 18:46 <+bridge> [ddnet] maybe they wanted || 18:46 <+bridge> [ddnet] aaaah 18:46 <+bridge> [ddnet] just strcmp being strcmp 😛 18:46 <+bridge> [ddnet] (and supporting < use case like that) 18:46 <+bridge> [ddnet] @heinrich5991 yes, but it's so fragile... even updating your compiler can break whole thing unless you export `extern "C"` things only 18:46 <+bridge> [ddnet] https://cdn.discordapp.com/attachments/293493549758939136/788462103336845312/Screenshot_2020-12-15_at_18.46.31.png 18:46 <+bridge> [ddnet] @Comrade that sounds like the problem of these languages not providing a stable ABI? ^^ 18:47 <+bridge> [ddnet] yes, but it seems they just don't care 18:47 <+bridge> [ddnet] OOOH 18:47 <+bridge> [ddnet] this supports h or help 18:47 <+bridge> [ddnet] yep 18:47 <+bridge> [ddnet] It's so hard to think when I'm so sleepy :/ 18:47 <+bridge> [ddnet] even modern things like Rust doesn't guarantee ABI stability as far as i know 18:47 <+bridge> [ddnet] even modern things like Rust don't guarantee ABI stability as far as i know 18:48 <+bridge> [ddnet] wym, even C++ has some sort of abi stability 18:48 <+bridge> [ddnet] but only barely across compilers AFAIK 18:49 <+bridge> [ddnet] @Learath2 yes, but then someone tries to compile a single library on Windows using MSVC and RIP... 😄 18:49 <+bridge> [ddnet] Yeah C++ is awful at it, that's why I gave it as an example 18:49 <+bridge> [ddnet] @Comrade I think there are initiatives to go for ABI stability in rust, but you're right, it doesn't exist right now 18:49 <+bridge> [ddnet] so you can't do some sort of rust shared library in a useful way 18:49 <+bridge> [ddnet] exactly 18:50 <+bridge> [ddnet] exporting C symbols is the only way 18:50 <+bridge> [ddnet] (except with a C ABI interface, that works, and works good in rust) 18:50 <+bridge> [ddnet] so why does it follow then that shared libraries are bad? 18:50 <+bridge> [ddnet] After an hour of reverse engineering xcrun, I finally figured out what's wrong 18:50 <+bridge> [ddnet] > [6:40 PM] Comrade: have you ever wondered about that dynamic libraries are quite bad concept? 18:50 <+bridge> [ddnet] maybe they work badly with some languages in practice, but them being a bad *concept*? 18:51 <+bridge> [ddnet] with most* 18:51 <+bridge> [ddnet] @Learath2 what is it? 18:52 <+bridge> [ddnet] @heinrich5991 you think it's programming languages' fault? 18:52 <+bridge> [ddnet] xcrun says the current sdk is "10.15.6" since it consults `_cltools_lookup_boot_system_sdk`, but CommandLineTools ships with SDK 11.0, and cmake finds that and uses the latest SDK 18:52 <+bridge> [ddnet] So I end up with 10.15 includes and 11.0 includes mixing 18:54 <+bridge> [ddnet] At the end of the day it's apples fault for including sqlite3, curl and zlib headers in their own sdk, who does that even 18:55 <+bridge> [ddnet] Actually at the end of the day it's this entire ecosystems fault. homebrew uses the current sdk, xcode uses the current sdk, commandline tools uses the latest sdk, apple in their suggestions say you should use the latest sdk 18:56 <+bridge> [ddnet] cmake follows apples recommendation, homebrew just is a mess 18:56 <+bridge> [ddnet] @ChillerDragon I feel like there should be a way to run PHP as different users e.g. per application instead of everything running as www-data 18:57 <+bridge> [ddnet] @timakro well php-fpm which does the interpreting runs as a certain user 18:57 <+bridge> [ddnet] Yeah www-data ... 18:57 <+bridge> [ddnet] You could probably run multiple instances of php-fpm per application 18:59 <+bridge> [ddnet] Yeah could work, but I don't want to experiment with that and go against the "running everything as www-data approach" that's built into nginx, php-fpm and the distro 19:04 <+bridge> [ddnet] @Comrade well, I'd say "programming language X does not work well with shared libraries", not "shared libraries are a bad concept" 19:05 <+bridge> [ddnet] is there any programming language other than C that works well with shared libraries? 19:05 <+bridge> [ddnet] Pascal maybe? 😄 19:05 <+bridge> [ddnet] idk. what about C#? 19:05 <+bridge> [ddnet] I'm not into that, so I don't know 19:06 <+bridge> [ddnet] Just because there is no good implementation doesn't mean the idea is bad 19:06 <+bridge> [ddnet] as far as i know you can easily load a DLL in C# and call some function from it, so probably yes 19:07 <+bridge> [ddnet] but does it work with non-MSVC DLLs? 😄 19:07 <+bridge> [ddnet] I'd guess they follow some ABI, so I'd guess yes 19:07 <+bridge> [ddnet] I "fixed" the issue. My new build command is `cmake .. && sed -i "" 's/10\.15/11.0/g' CMakeCache.txt && ninja && install_name_tool -change "/usr/local/opt/sdl2/lib/libSDL2-2.0.0.dylib" "/Users/learath2/Desktop/C/SDL/build/libSDL2-2.0.0.dylib" ./DDNet` 19:08 <+bridge> [ddnet] Overall amazing experience, I'm so glad I'm using this very mature and stable ecosystem 19:08 <+bridge> [ddnet] is macOS really that bad for devs? 😄 19:08 <+bridge> [ddnet] I only had to patch every piece of the build process together 19:09 <+bridge> [ddnet] To be honest with you, the fact that I only had to launch 3 instances of ghidra suggests this was quite a simple issue to debug 19:09 <+bridge> [ddnet] if you need 3 instances of ghidra to debug our build process, maybe there's something wrong with it… 😦 19:09 <+bridge> [ddnet] The install_name_tool one took 3-4 days, resulted in 2 SDL patches, and like 5 frameworks I had to reverse engineer 19:10 <+bridge> [ddnet] @heinrich5991 it's not our fault apple is out of their minds 19:10 <+bridge> [ddnet] @Learath2 I find your perseverance impressive 19:10 <+bridge> [ddnet] you're doing much better than I'd do 19:11 <+bridge> [ddnet] We could maybe include a heuristic in our CMakeLists to catch SDK mismatches? 19:11 <+bridge> [ddnet] oh no 😄 19:12 <+bridge> [ddnet] sounds good 19:12 <+bridge> [ddnet] I mean idk I could file a cmake bug but is it really a bug? Apple suggests you use the latest sdk when building. It's homebrew that's hardcoding the stupid 10.15 sdk in their pkg-configs 19:13 <+bridge> [ddnet] how do we take the 10.15 from its pkg-config? 19:13 <+bridge> [ddnet] I could file a homebrew issue but they are kinda right too, xcrun does report the 10.15 sdk being correct because it refers to the boot sdk version 19:13 <+bridge> [ddnet] @heinrich5991 pkg_check_modules 19:14 <+bridge> [ddnet] it results in a `pkg-config --variable=prefix ` 19:15 <+bridge> [ddnet] https://github.com/Homebrew/brew/blob/master/Library/Homebrew/os/mac/pkgconfig/10.15/libcurl.pc 19:16 <+bridge> [ddnet] So from there I get the 10.15 sdk in my includedir, and from cmake internals I get 11.0 as the sysroot 19:20 <+bridge> [ddnet] I found a prettier way to do it `SDKROOT=$(xcrun --show-sdk-path) cmake -GNinja ..` 19:20 <+bridge> [ddnet] Was reading through the cmake darwin initialization thing and noticed SDKROOT overrides all the heuristics 19:22 <+bridge> [ddnet] I'll hold off on filing a bug anywhere 19:23 <+bridge> [ddnet] oh finally I can check the resizing thing 😄 19:24 <+bridge> [ddnet] nice 🙂 19:25 <+bridge> [ddnet] Another interesting experience I had was when we were debugging the curl thing for osx cross compilation. I actually had to read a fair bit of clang source code for that one 19:28 <+bridge> [ddnet] @Jupstar ✪ not sure if it was you but we seem to have broken gfx_resizable somewhere along the way 19:29 <+bridge> [ddnet] I just remembered fullscreen was quite broken on macOS, @TsFreddie how did you even get it to launch? 19:29 <+bridge> [ddnet] Even 0.7 resorts to using "fake fullscreen" on macOS 19:31 <+bridge> [ddnet] If I launch ddnet fullscreen right now, it does some weird stuff then it starts windowed, yada yada we end up with the broken clipping, but changing resolutions fixes that quickly 20:18 <+bridge> [ddnet] <Дядя Женя> Fullscreen is Broken om every OS 20:19 <+bridge> [ddnet] <Дядя Женя> Useless function 20:19 <+bridge> [ddnet] <Дядя Женя> Fullscreen is Broken on every OS 20:19 <+bridge> [ddnet] huh 20:19 <+bridge> [ddnet] it's not useless, it can give more FPS 20:19 <+bridge> [ddnet] it never broke for me 20:19 <+bridge> [ddnet] <Дядя Женя> I mean in OS API 20:20 <+bridge> [ddnet] <Дядя Женя> I mean in OS API, not ddnet game 20:20 <+bridge> [ddnet] :tee_thinking: 20:29 <+bridge> [ddnet] how do you stop players from accidentally uploading their key material somewhere? 20:30 <+bridge> [ddnet] ideas: name the same something like "do_not_share.txt" 20:30 <+bridge> [ddnet] 2) spread the keys across multiple files which would make it annoying to upload 20:31 <+bridge> [ddnet] 3) use alternate streams, different positions to hide some key data 20:31 <+bridge> [ddnet] 4) encrypt it with the local user profile (works on windows, probably mac, don't know about linux). chrome does this I think 20:32 <+bridge> [ddnet] 5) encrypt it with some local details about the hardware, need some resilience in case the hardware changes 20:38 <+bridge> [ddnet] @heinrich5991 why are we stopiing people from uploading key material? 20:38 <+bridge> [ddnet] we don't have any key material 😛 20:38 <+bridge> [ddnet] :monkalaugh: 20:38 <+bridge> [ddnet] ye, if we do add it at some point 20:38 <+bridge> [ddnet] I'm thinking accounts again 20:38 <+bridge> [ddnet] sorry 😇 20:40 <+bridge> [ddnet] (hm, I shouldn't do emojis) 20:40 <+bridge> [ddnet] 😄 20:40 <+bridge> [ddnet] ah, I would put it in the keychain on mac, I bet there is a equivalent on windows, for linux we can try the gnome keyring, if not available we can try store it in an annoying way 20:41 <+bridge> [ddnet] yea, windows has something that chrome uses to encrypt the cookie db 20:41 <+bridge> [ddnet] (I know because chrome wouldn't let me borrow my cookies) 20:42 <+bridge> [ddnet] hm. but then it'd be hard for the user to transfer it to another PC 😦 20:44 <+bridge> [ddnet] oh btw, I was reverse engineering LeagueClient (because it wouldn't let me log in without riot client), I learned about a very effective way to analyze TLS traffic decrypted 20:44 <+bridge> [ddnet] SSLKEYLOGFILE, did you know this existed??? 20:44 <+bridge> [ddnet] Wireshark can directly parse this file and decrypt all the traffic 20:45 <+bridge> [ddnet] yes 20:45 <+bridge> [ddnet] it even works for the new quic libraries 20:45 <+bridge> [ddnet] at least for quiche (cloudflare's) 20:48 <+bridge> [ddnet] > In CClient::LoadMap in client.cpp you could probably remove the hash-checking code 20:48 <+bridge> [ddnet] @deen what i need to delete in the file? Sorry, im not C++ progranmer. 20:48 <+bridge> [ddnet] https://cdn.discordapp.com/attachments/293493549758939136/788492610087157770/20201215_224801.jpg 20:48 <+bridge> [ddnet] enhance 20:49 <+bridge> [ddnet] Entering the danger zone writing C++ code when you're not a C++ programmer xD 20:49 <+bridge> [ddnet] @heinrich5991 if that's not available it seems your best bet is frida, you can just hook whichever ssl library they are using 20:49 <+bridge> [ddnet] YES 20:49 <+bridge> [ddnet] frida is amazing 20:49 <+bridge> [ddnet] I used it before 20:49 <+bridge> [ddnet] it's sooo good, and I only used a tiny bit of it 20:49 <+bridge> [ddnet] I think I advertised it here before 😛 20:50 <+bridge> [ddnet] perhaps I got it from you, idk 20:50 <+bridge> [ddnet] Brilliant idea really, injecting a v8 engine into a program 20:50 <+bridge> [ddnet] hm, not sure how I feel about it being JS 20:50 <+bridge> [ddnet] but I guess it's the only real thing you can easily embed 20:50 <+bridge> [ddnet] so it's probably the right choice 20:51 <+bridge> [ddnet] @YupHio guess how I started in tw code 😛 20:51 <+bridge> [ddnet] Well they could have injected a wasm vm too 20:51 <+bridge> [ddnet] less easy to handle I guess 20:51 <+bridge> [ddnet] you only want to script and suddenly you have to handle ABIs and whatnot 20:52 <+bridge> [ddnet] well V8 hooks about as well into C as WASM afaik 20:52 <+bridge> [ddnet] ehm I mean for the "end user" using frida 20:52 <+bridge> [ddnet] if it was WASM, you'd have to compile your frida modules 20:53 <+bridge> [ddnet]
