[New-bugs-announce] [issue29947] In SocketServer, why not passing a factory instance for the RequestHandlerClass instead of the class itself?

[Dominic Mayers]

New submission from Dominic Mayers:

I am just curious to know if someone considered the idea of passing a factory instance that returns RequestHandlerClass instances instead of directly passing the class? It may affect existing handlers that read non local variables, but there should be a way to make the factory optional. The purpose is only aesthetic and a better organization of the code. I find it awkward to have to subclass the server every time that we have an handler that needs special objects, a database connection, a socket connection to another party, etc. The server class should have a single purpose: accept a request and pass it to an handler. We should only need to subclass a server when we need to do that in a different way : TCP vs UDP, Unix Vs INET, etc. The usage is simpler and more natural. Instead of subclassing the server, we create a factory for the handler.
