Unable to send handles with uv_write2

[nikneym]

Hi, I'm trying to send handles over pipes. I've created a socketpair and sent one end to a new thread and when I try to read/write between them, it just works. In the following code though, I'm sending accepted TCP connections to a thread via write2 but it doesn't work.

local uv = require "luv"

local fds = uv.socketpair(nil, nil, { nonblock = true }, { nonblock = true })

-- setup worker thread
uv.new_thread(function(fd)
  local uv = require "luv"

  local pipe = uv.new_pipe(false)
  pipe:open(fd)

  pipe:listen(128, function()
    local client = uv.new_tcp()
    pipe:accept(client)

    print "handle received by worker"
    client:close()
  end)

  uv.run()
end, fds[2])

-- setup writer pipe & tcp server
local pipe = uv.new_pipe(true)
pipe:open(fds[1])

local server = uv.new_tcp()
server:bind("127.0.0.1", 3000)

server:listen(128, function()
  local client = uv.new_tcp()
  server:accept(client)

  -- send it to worker thread
  pipe:write2("", client)
end)

uv.run()
