Quitting neovim takes a long time when toggling git ignore folders

[itsramiel]

Description

When I toggle a git ignore folders and javascript's node_modules is visible it takes an unusual longer time to quit neovim. I dont mean it only happens with node_modules but tht is my use case. Check the video where I have only nvim-tree as a dependency and I quit neovim when git ignore folders are hidden vs when they are visible.

One weird thing is that if I delete the .gitignore file and the node_modules is visible from the start then it quits just as fast as usual. It is only when I toggle the git ignore files from hidden to visible

Clean room replication

I tested it without any other plugin

vim.g.loaded_netrw = 1
vim.g.loaded_netrwPlugin = 1

vim.cmd [[set runtimepath=$VIMRUNTIME]]
vim.cmd [[set packpath=/tmp/nvt-min/site]]
local package_root = "/tmp/nvt-min/site/pack"
local install_path = package_root .. "/packer/start/packer.nvim"
local function load_plugins()
  require("packer").startup {
    {
      "wbthomason/packer.nvim",
      "nvim-tree/nvim-tree.lua",
      "nvim-tree/nvim-web-devicons",
      -- ADD PLUGINS THAT ARE _NECESSARY_ FOR REPRODUCING THE ISSUE
    },
    config = {
      package_root = package_root,
      compile_path = install_path .. "/plugin/packer_compiled.lua",
      display = { non_interactive = true },
    },
  }
end
if vim.fn.isdirectory(install_path) == 0 then
  print "Installing nvim-tree and dependencies."
  vim.fn.system { "git", "clone", "--depth=1", "https://github.com/wbthomason/packer.nvim", install_path }
end
load_plugins()
require("packer").sync()
vim.cmd [[autocmd User PackerComplete ++once echo "Ready!" | lua setup()]]
vim.opt.termguicolors = true
vim.opt.cursorline = true

-- MODIFY NVIM-TREE SETTINGS THAT ARE _NECESSARY_ FOR REPRODUCING THE ISSUE
_G.setup = function()
  require("nvim-tree").setup {}
end

-- UNCOMMENT this block for diagnostics issues, substituting pattern and cmd as appropriate.
-- Requires diagnostics.enable = true in setup.
--[[
vim.api.nvim_create_autocmd("FileType", {
  pattern = "lua",
  callback = function()
    vim.lsp.start { cmd = { "lua-language-server" } }
  end,
})
]]

### Steps to reproduce

1. create a directory and cd into it
2. run `npm init -y` to initialize an empty js project
3. run `npm install {add many packages to have a large node_modules}`
4. add a .gitignore with `node_modules`
5. try quitting neovim after toggling gitignore files vs not and see the quitting difference

### Expected behavior

I expect neovim to quit just as fast even when ignored git files are shown

### Actual behavior

Neovim quits slow when hidden git files are shown

Attempted replication with this 900MB setup:

git clone git@github.com:facebook/create-react-app.git
cd create-react-app
yarn

I and E on node_modules. No performance issue at any step. However, I am running on linux with btrfs.

This macos user had a similar issue, the root cause being the filesystem watchers. Resolution: https://github.com/nvim-tree/nvim-tree.lua/issues/2438#issuecomment-1864299051

  filesystem_watchers = {
    ignore_dirs = {
      "node_modules"
    },
  },

Which filesystem are you using? Is it case sensitive? Are you using full disk encryption?

This macos user had a similar issue, the root cause being the filesystem watchers. Resolution: #2438 (comment)

  filesystem_watchers = {
    ignore_dirs = {
      "node_modules"
    },
  },

This solved it for me

I dont really know the answer to these questions. I am happy to find out if you can let me know how.

Feel free to close the issue or keep it open if you want to dig deeper and I can help if you need me to check something

Just encryption would be great.

It would be great if you could collect a log, indicating the time you quit.

log = {
  enable = true,
  truncate = true,
  types = {
    all = false,
    config = false,
    copy_paste = false,
    dev = false,
    diagnostics = false,
    git = false,
    profile = true,
    watcher = true,
  },
},

I'm not certain there's much we can do about this; node modules is problematic for many tools and is ignored by default: #3649

It might be time to add that, given the number of issues this has caused.
