1. data Library login problem
   [!]: data.py Has been refactored on Database.py

def __in__(username) -> bool:
    return >> encode << (username) in data

2. Server side Database.handler problem

    def login_data(self):
        while self.isOpen():
            try:
                response = json.loads(self.recv())
                return response["type"], response["username"], response["password"]
            except TypeError:
                self.quit()
     ...
    @ignore
    def forever_receive(self):
        while self.isOpen():
            result, reason, username = Database.handler(*self.login_data())
            self.send(json.dumps({
    "result": result, "reason": reason}))
            if result:
                self.username = username
                break
         ...

3. Client login / The registration screen After successful registration, the waiting interface is still running

    def handle(self, dictionary: (dict, str)):
        >> self.loading_dialog.close() <<
        if isinstance(dictionary, dict):
            result = dictionary.get("result", False)
            reason = dictionary.get("reason", False)

            if not result:
                self.err_handle(reason)
            else:
                self.successful = True
                self.close()

        self.Enable(True)

4. File transfer time detection problem

5. Warning repair
6. Reduce redundant
