`file` and `arguments` are accessed using the square bracket syntax, while `output` is accessed using `.get()`. This commit uses square brackets for all three. This will throw a `KeyError` if `compilation_database` does not have the key, which is the correct behaviour IMO.
The `<sys/stat.h>` include in `launcher.c` is only used to check if the executable is a symlink on macOS. Therefore it is not needed on other platforms.
The macOS specific `package()` code changes the directory. This didn't cause any problems before 9135387cfa since `compile_commands.json` was written to the filesystem before `package()` was called. This is not the case anymore, which results in `compile_commands.json` being written into the `kitty.app` bundle. I fixed the problem by using a context manager to change the direcctory back after `kitty.app` was created.
Now there is only one launcher. Which means it can be used to start
kitty with profiling and ASAN in the natural way. The recommended
way to run kitty from source is now:
./kitty/launcher/kitty
The launcher also automatically re-execs to resolve symlinks on macOS.
I see a couple problems with using git to determine the files to delete:
- git needs to be installed
- The manual cleaning code is supposed to function correctly, so why not always use it? That way bugs in the manual cleaning code are also more likely to get discovered
- If some files ignored by git should not be deleted, they need to be added to a sort of blacklist. If some files should be deleted by the manual cleanup code, they need to be added to a sort of whitelist. If someone forgets to add files to one of these lists, then not deleting files that should be deleted is better than deleting files that should not be deleted.
Calling `Env()` without the `ldpaths` parameter after a call with the `ldpaths` parameter, keeps the list from the first call because the argument is mutable. This is probably not what was intended. This commit fixes this issue and also reverts a change to two lines introduced in 091e74d618, which was probably a workaround for this issue.
