Any changes to the file tree are ignored

How are you using the lua-language-server?

Visual Studio Code Extension (sumneko.lua)

Which OS are you using?

Linux

What is the issue affecting?

Annotations, Type Checking, Completion, Diagnostics/Syntax Checking, Hover

Expected Behaviour

When you make any changes to the workspace's file tree (e.g. add a new file, rename a file), LuaLS becomes aware of them.

Actual Behaviour

New/renamed files are only recognized so long as they are open in the editor and completely forgotten about once closed.

Reproduction steps

1. Add a new file to your existing workspace with the following content:

---@class TestClass
local TestClass = {}

function TestClass.test()
end

return TestClass

2. Save it and close the editor tab.
3. Require this file into a local in some other, preexisting file.
4. Observe that the local is of unknown type.

Additional Notes

Re-running diagnostics doesn't fix this. The only workaround I have found is to completely restart VSCode.

From my limited understanding of LuaLS code, I think it has something to do with cached files. And there is no way to discard and rebuild the cache without exiting VSCode that I could find.

Log File

No response

まず、LuaLS による workspace file-tree の変更処理と、報告で問題になっている cached-file のライフサイクルを追跡します。提示された add、save、close、require のシーケンスを再現し、その後、VS Code を再起動せずに、ファイルを閉じた後も diagnostics が新規または名前変更されたファイルを認識することを確認します。
