If requested, this is the deepest level of memory issue debugging possible.
Prepare yourself mentally, and then:
_Do this in the tty, with no Hyprland instances running_
recommended to do in tty
Clone hyprland: `git clone --recursive https://github.com/hyprwm/Hyprland`
clone wayland (`git clone --recursive https://gitlab.freedesktop.org/wayland/wayland`)
clone hyprland (`git clone --recursive https://github.com/hyprwm/Hyprland`)
cd to it: `cd Hyprland`
add these envs to your Hyprland config to reset ASAN_OPTIONS for children and set LD_PRELOAD:
```
env = ASAN_OPTIONS,detect_odr_violation=0
env = LD_PRELOAD,/usr/lib/libasan.so.8.0.0
```
_Please note to check the asan .so version on your system with `ls /usr/lib | grep libasan`_
`make asan`
wayland:
```
meson ./build --prefix=/usr --buildtype=debug -Db_sanitize=address
sudo ninja -C build install
```
This will compile everything and launch Hyprland.
The Wayland build will likely fail citing missing dependencies such as Doxygen, these
dependencies will likely be available from your distros package manager.
Reproduce your crash. Hyprland will exit back to the tty.
hyprland:
```
cmake --no-warn-unused-cli -DCMAKE_BUILD_TYPE:STRING=Debug -DWITH_ASAN:STRING=True -S . -B ./build -G Ninja
cmake --build ./build --config Debug --target all -j`nproc 2>/dev/null || getconf NPROCESSORS_CONF`
cd ./subprojects/wlroots
rm -rf ./build
meson ./build --prefix=/usr --buildtype=debug -Db_sanitize=address
ninja -C build
cd ../..
sudo make install
```
You can now launch your regular Hyprland session.
Exit Hyprland to a TTY, cd to the cloned hyprland, and launch it:
```
ASAN_OPTIONS="detect_odr_violation=0,log_path=asan.log" ./build/Hyprland -c ~/.config/hypr/hyprland.conf
```
Now, in either `cwd`, `~` or `./build`, search for file(s) named `asan.log.XXXXX` where XXXXX is a number.
open your terminal
Do whatever you used to do in order to crash the compositor.
Please note many apps will refuse to launch. Notably complex applications, like e.g. browsers.
Once it crashes, go to `~` or `cwd` and look for `asan.log.XXXXX` files. Zip all and attach to the issue.
once you are done, to revert your horribleness of no app opening without the ld preload just go to the cloned wayland and do
```
sudo rm -rf ./build
meson ./build --prefix=/usr --buildtype=release
sudo ninja -C build install
```
To revert the changes to hyprland and wlroots, do inside the cloned hyprland:
```
make all && sudo make install
```
Zip all of them up and attach to your issue.
