[Bug] luarocks fails when neovim opened with file as an argument

[boltlessengineer]

I found error when opening neovim with file as an argument without tree-sitter parser.
Loading file with :e test.rs after opening neovim is fine.

Reproduce

• run nvim test.rs
• check :Rocks log

:Rocks log output:

rocks.toml

[rocks]

[plugins]
"rocks.nvim" = "2.35.1"
"rocks-treesitter.nvim" = "scm"

[treesitter]
auto_highlight = "all"

By adjusting some internal code, I found the error was happening while running first search --all command:

luarocks --force-lock --lua-version=5.1 --tree=/home/ubuntu/.local/share/nvim_rocks/rocks --server='https://nvim-neorocks.github.io/rocks-binaries-dev/' --server='https://luarocks.org/manifests/neorocks/' --server='https://nvim-neorocks.github.io/rocks-binaries/' search --porcelain --all --dev

which was executed from:

rocks-treesitter.nvim/lua/rocks_treesitter/highlight.lua

Lines 40 to 50 in 59903dc

	local function find_parser_rock(lang, callback)
	local rock_name = "tree-sitter-" .. lang
	local rocks = api.try_get_cached_rocks()
	if rocks and rocks[rock_name] then
	return callback(rocks[rock_name])
	end
	-- Cache may not have been populated. Query luarocks.
	api.query_luarocks_rocks(function(luarocks_rocks)
	callback(luarocks_rocks[rock_name] or {})
	end)
	end

But I don’t get any error when I manually run that command with luarocks 3.11.1-dev version.
Even :=require("rocks.api").query_luarocks_rocks(function(res) vim.print(res["tree-sitter-rust"]) end) was fine.

I guess some initialization hasn’t executed before the FileType autocommand but couldn’t find it.

Hey 👋

thanks for the report.
This is an issue with the luarocks locking mechanism.
As a workaround, I guess we have to synchronise all invocations of the luarocks CLI.
