`OptionSet` is triggered when `tree` open in some cases.

[peter-lyr]

Description

I like the tree to stay open, but one day I run nvim-qt in a somewhat underperforming Windows 10 computer, I found out that every time I open the tree, I get stuck until I close the tree.

Then I tried to find out what causes it to be stuck, in other words, what makes OptionSet to be triggered repeatedly.

Neovim version

NVIM v0.9.1
Build type: RelWithDebInfo
LuaJIT 2.1.0-beta3

Operating system and version

Windows 10, Windows 11

nvim-tree version

3b62c6b

Clean room replication

for name, url in pairs {
  tree = 'https://github.com/nvim-tree/nvim-tree.lua.git',
  devicons = 'https://github.com/nvim-tree/nvim-web-devicons.git',
} do
  local install_path = vim.fn.fnamemodify([[C:\Users\llydr\Desktop\nv\nvt-min\]] .. name, ':p') -- TODO: Please change the path here!!!
  if vim.fn.isdirectory(install_path) == 0 then vim.fn.system { 'git', 'clone', '--depth=1', url, install_path } end
  vim.opt.runtimepath:append(install_path)
end

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

require('nvim-tree').setup()
print 'Minimal Config Ready!'

local file = [[C:\Users\llydr\Desktop\nv\nvt-min\nvt-min.log]] -- TODO: Please change the path here!!!
vim.api.nvim_create_autocmd({ "CursorMoved", "TextChanged", "OptionSet", }, {
  callback = function(ev)
    vim.fn.writefile({ string.format([[%-3.3f %-2d %-20s - "%s"]], os.clock(), ev.buf, ev.event, ev.file) }, file, 'a')
  end
})

Steps to reproduce

1. cd C:\Users\llydr\Desktop\nv\nvt-min
2. which nvim

/c/Users/llydr/Desktop/nv/nvim-win64/bin/nvim

3. nvim -nu nvt-min.lua
4. :NvimTreeOpen
5. press - to go Up or press <c-]> to CD into some folder.
6. observe whether the nvt.min.log file keeps growing.
7. When I type :NvimTreeOpen and press Enter, it just keeps getting bigger and bigger.

Expected behavior

When the tree remains open, regardless of whether the tree is active or inactive, and regardless of whether the tree is focused lost or gained, the OptionSet is not triggered repeatedly.

Actual behavior

CursorMoved, TextChanged, OptionSet are triggered repeatedly.

It will not be always triggered.

For example, when the tree is:

~\Desktop\nv\nvt-min/..
  devicons
  tree
  󰌱 nvt-min.log
   nvt-min.lua

or

~\Desktop\nv\nvt-min/..
  devicons
  tree
    .git
    .github
    .hooks
    doc
    lua
    scripts
     .editorconfig
     .luacheckrc
     .luarc.json
     .stylua.toml
     CONTRIBUTING.md
     LICENSE
     README.md
  󰌱 nvt-min.log
   nvt-min.lua

They would be triggered.

But when I CD into tree or devicons, They would not be triggered.
Like this:

~\Desktop\nv\nvt-min\tree/..
  .git
  .github
  .hooks
  doc
  lua
  scripts
   .editorconfig
   .luacheckrc
   .luarc.json
   .stylua.toml

Thank you for the replication. This works nicely:

local log = require("nvim-tree.log")

vim.api.nvim_create_autocmd({ "CursorMoved", "TextChanged", "OptionSet" }, {
  callback = function(ev)
    log.line("dev", [[%-2d %-20s - "%s"]], ev.buf, ev.event, ev.file)
  end,
})

[alex-courtis]

CursorMoved will happen repeatedly on every buffer. There is nothing specific to nvim-tree and nothing that can be done about it.

[alex-courtis]

Following your reproduction steps I get the following output for:

vim.api.nvim_create_autocmd({ "OptionSet" }, {
  callback = function(ev)
    log.line("dev", [[%-2d %s %s %s %s '%s' -> '%s']], ev.buf, ev.file, vim.v.option_type, vim.v.option_command, ev.match, vim.v.option_old, vim.v.option_new)
  end,
})

[2023-07-23 17:01:00] [dev] 0   global set eventignore 'BufEnter' -> ''

This activity is reasonable; most options are local and there is little use case for another plugin to listen to them.

[alex-courtis]

There's almost no TextChanged activity for the nvim-tree buffer, nor any other buffers.

vim.api.nvim_create_autocmd({ "TextChanged" }, {
  callback = function(ev)
    log.line("dev", [[%-2d %-20s - "%s"]], ev.buf, ev.event, ev.file)
  end,
})

[2023-07-23 17:05:24] [dev] 2  TextChanged          - "/home/alex/src/linux/NvimTree_1"

[alex-courtis]

I'm clearly not seeing the problem here. These events are very common and will be fired a lot.

@peter-lyr please provide the output of the above three cases.

@alex-courtis Thank you for answering my question.

After changing my logging to nvim-tree.log, it works nicely too on my Windows 11 PC. It's really a good way to debug this problem using such as vim.v.option_new.

I'd try on my Windows 10 PC tomorrow at work to find the cause of the high CPU usage when tree is open.

This is a good start. We can see whether it is excessive events or some other issue. nvim-qt vs standard neovim will be a good test.

[peter-lyr]

I can reproduce this issue on my Windows 10 now.

Before I run nvim -nu nvt-min.lua, I run set TEMP=D:\Desktop\nv\nvt-min\ and nvim-tree log file change to D:\Desktop\nv\nvt-min\nvim\nvim-tree.log.

1. D: and cd D:\Desktop\nv\nvt-min
2. md nvim
3. nvim -nu nvt-min.lua
4. :NvimTreeOpen
5. nvim\nvim-tree.log start to grows.
6. When I CD devicons or tree, it stops.

Maybe it's becuase tree nodes change and tree is refreshing?

Thanks for the detailed digging!

This does seem to be a windows specific issue. I'm seeing logs below once on tree open, then no further OptionSets.

Unfortunately the event passed to the OptionSet callback is not useful as it doesn't indicate which buffer the local option might apply to. It's always a modifiable set/reset.

The modifiable set/reset is done when the tree is drawn, which is to be expected, although tree draws are kept to a minimum.

Perhaps the tree is being excessively refreshed following filesystem events.

I'm not really sure how much further I can get with this one.

Suggestions:

• log.types.watcher = true to see which filesystem events are being seen
• filesystem_watchers.enable = false as another filesystem watcher experiment
• use WSL and see if you experience the same issue
