Expected Behaviour

When the language server processes a Lua file, it should use the .luarc.json file that is closest (in the chain of parent folders) to the file being opened. So in this case:

dir1
 |- .luarc.json
  \_ dir2
        |- .luarc.json
         \_ code.lua

Opening code.lua should use dir2/.luarc.json.

Actual Behaviour

Non-deterministic behavior: sometimes it uses dir1/.luarc.json and sometimes it uses dir2/.luarc.json. This is a big problem e.g. in cases where those two files specify different versions of Lua.

Reproduction steps

Create the directory/file structure above, specifying different version of Lua in each one, then put some code in code.lua that is sensitive to the version, then run lua-language-server (I run it through Neovim) on code.lua, and observe sometimes it assumes one version of Lua and other times it uses the other.

Deleting dir1/.luarc.json then eliminates the non-deterministic behavior and it always uses dir2/.luarc.json.

Commencez par reproduire la structure des répertoires avec deux fichiers .luarc.json et ouvrir code.lua dans Neovim. Suivez la manière dont lua-language-server découvre les fichiers de configuration et comparez plusieurs exécutions avec différentes versions de Lua configurées. Le travail est terminé lorsque la configuration du répertoire parent le plus proche est sélectionnée de manière cohérente et que la reproduction n’affiche plus de diagnostics non déterministes.
