[ruby-core:108637] [Ruby master Bug#18792] Socket.tcp throws `getaddrinfo': no implicit conversion of Hash into String

Issue #18792 has been updated by midnight (Sarun R).


It's the Ruby 3 things. They don't try to match method parameters for you anymore.

You have to do it explicitly:
~~~Ruby
Socket.tcp(host, port, **socket_opts)
~~~

Hello,

I was using ruby 2.5.3 for a while, but now it's EOL, trying to port my code to ruby 3.0.4. 
Same piece of code is throwing error on below code snippet.

Below piece of code works fine on ruby 2.5.3, but throws error on ruby 3.0.4. 
I investigated socket.rb, it turns out that local_host is Hash in latest ruby, in older version it was NilClass.

I have a sample running application on local VM. 

``` ruby
require 'socket'

host = "192.168.56.100"
port = 8081
socket_opts = {
   connect_timeout: 10,
}

Socket.tcp(host, port, socket_opts)

```
