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.

Beginne damit, die Verzeichnisstruktur mit zwei .luarc.json-Dateien nachzubilden und code.lua mit Neovim zu öffnen. Verfolge, wie lua-language-server Konfigurationsdateien erkennt, und vergleiche wiederholte Ausführungen mit unterschiedlichen konfigurierten Lua-Versionen. Erledigt ist die Aufgabe, wenn die Konfiguration des nächsten übergeordneten Verzeichnisses konsistent ausgewählt wird und die Reproduktion keine nichtdeterministischen Diagnosen mehr zeigt.
