Support for PyMySQL

Inizia da prepare_connect_info e traccia il percorso con cui la sua proprietà port raggiunge la validazione di PyMySQL connections.py. Verifica il flusso di connessione esistente con una porta intera e conferma che il supporto funzioni senza compromettere gli altri connettori; il lavoro è completato quando una connessione PyMySQL accetta la porta configurata.

Describe the feature

Support the usage of the pymysql connector

Use Case

The project I'm working on uses pymysql, I tried to pass the Connect class to the AwsWrapperConnection, however, it's failing because it's casting the port argument to a string, even though I'm passing an int.

Code that's turning the port into a string:

def prepare_connect_info(self, host_info: HostInfo, props: Properties) -> Properties:
        prop_copy: Properties = Properties(props.copy())

        prop_copy["host"] = host_info.host

        if host_info.is_port_specified():
            prop_copy["port"] = str(host_info.port)

        PropertiesUtils.remove_wrapper_props(prop_copy)
        return prop_copy

pymysql code enforcing the int type:
connections.py

// ...
self.port = port or 3306
        if type(self.port) is not int:
            raise ValueError("port should be of type int")
// ...

I wonder if it's possible to remove that cast to string or adapt somehow to support pymysql. I'm not sure if that's all it's going to take, though.

Proposed Solution

Remove the cast to string for the port

if host_info.is_port_specified():
            prop_copy["port"] = host_info.port

or a condition for the pymysql library
