bug: missing idempotence in update lazy-lock.json between windows and unix

[orumin]

Did you check docs and existing issues?

• I have read all the lazy.nvim docs
• I have searched the existing issues of lazy.nvim
• I have searched the existing issues of plugins related to this issue

Neovim version (nvim -v)

0.10.0 66823fdb

Operating system/version

Ubuntu 22.04 (WSL) and Windows 11 22H2

Describe the bug

lazy-lock.json updated in Linux has newline as 'LF',
but the file updated in Windows has newline as 'CRLF'.
there is no consistency.

Steps To Reproduce

1. update lazy-lock.json on Linux (WSL2)
   • the file has newline as 'LF'
2. update lazy-lock.json on Windows
3. the file's newline is replaced by 'CRLF'

Expected Behavior

saved lazy-lock.json has same newline character code wherever updated.

the problem caused by file open mode in lazy.manage.lock.lua.

lazy.nvim/lua/lazy/manage/lock.lua

Line 12 in f0cfbf9

local f = assert(io.open(Config.options.lockfile, "w"))

Windows's libc fwrite(3) converts LF to CRLF in auto if file is opened with "w" mode.
use "wb" mode instead of "w", this problem will be resolved.

Repro

-- DO NOT change the paths and don't remove the colorscheme
local root = vim.fn.fnamemodify("./.repro", ":p")

-- set stdpaths to use .repro
for _, name in ipairs({ "config", "data", "state", "cache" }) do
  vim.env[("XDG_%s_HOME"):format(name:upper())] = root .. "/" .. name
end

-- bootstrap lazy
local lazypath = root .. "/plugins/lazy.nvim"
if not vim.loop.fs_stat(lazypath) then
  vim.fn.system({ "git", "clone", "--filter=blob:none", "https://github.com/folke/lazy.nvim.git", lazypath, })
end
vim.opt.runtimepath:prepend(lazypath)

-- install plugins
local plugins = {
  "folke/tokyonight.nvim",
  -- add any other plugins here
}
require("lazy").setup(plugins, {
  root = root .. "/plugins",
})

vim.cmd.colorscheme("tokyonight")
-- add anything else here
