### First stage
|
|
|
|
- [✓] Server starts
|
|
- [✓] It accepts two params, ./ircserv <port> <password>
|
|
- [✓] The server accepts one user, user can send messages and we can see from server
|
|
- [✓] Only 1 poll()
|
|
|
|
### Second stage
|
|
|
|
- [✓] Server can handle multiple clients simultaneously
|
|
- [✓] Manage SO_REUSEADDR (restarting server fails to bind same port)
|
|
|
|
### Third stage
|
|
|
|
- [✓] Dispatcher (select function for each command)
|
|
- [✓] Implement generic parser (extract command and pass args to command function)
|
|
- [✓] Client has nickname and username
|
|
- [✓] PASS command for authenticate
|
|
|
|
### Fourth stage
|
|
|
|
- [✓] Client can create/connect to channels
|
|
- [✓] JOIN command (user can create channel)
|
|
- [✓] PRIVMSG command (send message to a channel)
|
|
- [✓] QUIT command
|
|
- [✓] PRIVMSG difference between channels (#) and users
|
|
|
|
### Fifth stage
|
|
|
|
- [ ] PART command (user leaves a channel)
|
|
- [✓] KICK command (operator removes a user from channel)
|
|
- [ ] INVITE command (operator invites a user to channel)
|
|
- [ ] TOPIC command (view or set channel topic)
|
|
