This is when you finally understand why a URL starts with HTTP

webserv's Issues

test issue

Configuration

Start

• Config.cpp and header
• Parse and Store configuration options
• Validate configuration
• Log Configuration Errors
• Fallback to default Settings

Client

Client Implementation

• Client.cpp and Client.hpp
• Define Client Class
• Manage client state
• Track Client's connection status
• buffer client data
• send and receive Data

Server

Start

• Create server cpp and header file
• define server class

Implement CPP file

• constructor in canonical form
• init server variables
  • Port, Host, Routes

Sockets

• Create Non-blocking Socket and Bind (use SOCK_NONBLOCK macro)
• Handle Socket Errors
• Throw Exception on Error

Event

• Set up Event Loop
• Use poll or equivalent
• Handle incoming connections
• Accept new clients connections
• Manage client connections in Event Loop

Handle HTTP requests

• Parse HTTP headers
• Determine Request Type:
  • GET
    • Server Static Content
    • Locate Requested File
    • Send File to Client
    • Handle 404 Errors
  • POST
    • Handle Form Submissions
    • Parse Form Data
    • Save uploaded Files
    • Send Response to Client
  • DELETE
    • Delete resources
    • Verify Resources existence
    • Remove resource
    • Send confirmation to client

Implement CGI Handlign

• Detect CGI request based on Extension
• Execute CGI Script with execve
• Pass Environment variables to CGI
• Capture CGI Output
• Send CGI responde to client

Main file

• Initializer server setup
• parse configuration file
  • load configuration parameter
  • set default config file if not provided

Set default path if not have a configuration file

Create Project Structure

• create makefile
• create directories structure

Use one poll() or equivalent

consider poll() to equivalent that we are using (epoll())

• poll() must check read and write at the same time
• never do a read or a write operation without going through poll()
• checking the value of errno is forbidden after a read or a write operation.
• don't use poll() before reading your configuration file

Take a configuration file as argument

Testing and debugging

Testing

• Write Unit Tests with google test suite
• Test Server Response Codes
• Test Static file Serving
• Tests CGI Execution

Debugging

• Stress Test Server
• Simulate Multiple Clients Connections
• Verify server stability

Tests

updated tests to still working with new implementation

Server must never block and the client can be bounced properly
