Writing a multithreaded, multicall XML-RPC server

You can make your XML-RPC server accept multiple calls simultaneously. This means that multiple function calls can return a single result. In addition to this, if your server is multithreaded, then you can execute more code after the server is launched in a single thread. The program's main thread will not be blocked in this manner.

How to do it...

We can create a ServerThread class inheriting from the threading. Thread class and wrap a SimpleXMLRPCServer instance in an attribute of this class. This can be set up to accept multiple calls.

Then, we can create two functions: one launches the multithreaded, multicall XML-RPC server, and the other creates a client to that server.

Listing 7.2 gives the code for writing a multithreaded, multicall XML-RPC server, as shown:
