[BUG] Double Workspace Loaded on Sumneko 2.6.0

[tigorlazuardi]

Two workspaces are loaded in the newest Sumneko lua server when using lua-dev. I can confirm this does not occur when not using lua-dev in lspconfig.

The effect of loading two workspaces is super slow startup for the lsp, and super slow autocompletes and goto definitions.

The proof of two workspaces loaded can be seen in the screenshot by using lsp_status indicator in the status line (the bottom row).

This is most likely caused by the new workspaces feature. Can be seen from this compare tag commits.

I'm experiencing this too.

@folke can you check this one out? Because of this, the loading time has increased dramatically.

I don't really see anything I can do to fix this?

Seems like a bug in Sumneko? As far as I can see, there's only one lsp client.

Thank you for the answer. Downgrading sumneko_lua to v2.5.6 fixed the issue. It seems best to wait until sumneko_lua to be stable before going to v2.6.x or higher.

I consider this issue from my side closed, but left the decision to close it to you.

Hi!
Could this be related?

warn message in ~/.cache/nvim/lsp.log:

[WARN][2022-01-21 14:39:09] .../lua/vim/lsp.lua:812	"server_request: no handler found for"	"workspace/semanticTokens/refresh"

I'm getting 100% CPU usage and no response from the server.

I've also tried it without applying

require("lua-dev").setup { lspconfig = M.general }

and the warning keeps appearing (I assume it has to do with sumneko_lua) but the CPU usage won't rise...

The reason for this is LuaLS/lua-language-server#1596
