Non-deterministic behavior when there are multiple parent folders with .luarc.json.

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.

I currently don't have the energy to delve into non-VSCode issues. You can try using the multi-workspace feature to enable a workspace for each of these two directories.

@sumneko how do you know this is a non-VSCode issue? Have you tried to reproduce it with VSCode?

[sumneko]

VSCode requires an explicit specification of the workspace, so just specify dir1 as the workspace. But as far as I know, neovim will automatically use the directory where your first opened file is located as the workspace. Therefore, depending on the first opened file, the workspace may be dir1 or dir2.
