[BUG]Copas 1.1.4 connect bug

[Linker <linker.m.lin@...>]

Hi,All,

There is a copas-test function:

local client

local co_socket

local function connect()

if client then client:close(); end

client=socket.tcp()

co_socket=copas.wrap(client)

co_socket:settimeout(10)

while true do

local ret,err=copas.connect(client,'127.0.0.1',12345)

print(ret,err)

if ret then break;end

end

end

If the server is not ready first , the copas will block lua vm at copas.connect and forever.

I added some prints  to connect function:

-- waits until connection is completed

function connect(skt,host, port)

       skt:settimeout(0)

       local ret,err = skt:connect (host, port)

  if err=='timeout' then print('connect timeout.'); end

       if ret or err ~= "timeout" then

 print'ret'

    return ret, err

  end

   _writing_log[skt] = os.time()

       coroutine.yield(skt, _writing)

  print'try connect'

       ret,err = skt:connect (host, port)

   _writing_log[skt] = nil

       if (err=="already connected") then

               return 1

       end

       return ret, err

end

the output is :

connect timeout.

Why?

Is it a copas bug?

Thanks.
