Python Sockets Project

This is a simple Python project that demonstrates socket communication between a server and a client. It includes a server implementation (server.py), a daemonized server (daemon_server.py), and a client (client.py).

Installation

1. Navigate to the project directory:

   cd your-sockets-project

2. Create and activate a virtual environment:

   python -m venv venv
   source venv/bin/activate

3. Install the required dependencies:

   pip install -r requirements.txt

Usage

Running the Server

Basic Server

In server.py, adjust the SERVER and PORT literals as needed:

# Update these values accordingly
SERVER = "localhost"
PORT = 8080

Run the basic server:

python server.py

Daemonized Server

Run the daemonized server:

python daemon_server.py

It will generate a temporary 'daemon_server.pid' file in the tmp folder containing a process ID value. Run the following command to stop the daemon:

kill $(cat tmp/daemon_server.pid)

Configuration

The project includes a configuration file (config.ini) with the following settings:

[text_file] Section:

• linuxpath: The path to the text file used for searching string sent by client.
• reread_on_query: Whether to reread the file on each client query (True/False).

[ssl] Section:

• ssl_auth: Whether SSL authentication is enabled (True/False).
• certfile: The path to the SSL certificate file.
• keyfile: The path to the SSL key file.

Running the Client

In client.py, adjust the SERVER and PORT literals as needed:

# Update these values accordingly
SERVER = "localhost"
PORT = 8080

Run the client:

python client.py

Testing

This project uses pytest for testing. In test files contained in tests folder, adjust the SERVER and PORT literals as needed:

# Update these values accordingly
SERVER = "localhost"
PORT = 8080

Run the tests with the following command:

pytest

Run specific test files using:

pytest ./tests/{name of test file}

For the file search speed tests it is useful to add the -s flag:

pytest -s ./tests/{name of test file}

Type Checking

Type checking is performed using mypy. Run mypy with the following command:

mypy {name of file}
