ircserv

An IRC (Internet Relay Chat) server in C++ 98.

Execution order:

./ircserv <port> <password>

• port: the port on which the IRC server will be listening to for incoming IRC connections.
• password: the connection password, any IRC client should have one in order to connect to the server.

NOTTODO

• Develop a client.
• Handle server-to-server communication.
• Forking and block operations.
• Writing spaghetti code

TODO

• Develop an IRC server in c++ 98.
• Handle multiple clients at the same time.
• Use only 1 poll() (or equivalent) for handling all these operations (read, write, listen, and so forth).
• Choosing and IRC client as reference.
• Connecting te client with the server without encountering any error.
• Implement communication between client and server via TCP/IP (v4 or v6).
• The client must be able to connect to the server just like any other official IRC server.
• Implement the following features:
  • Authentication, nickname, username.
  • Joining a channel, send and recieve private message using the client.
  • Forwarding all the messages sent from one client to everyone else that joined the channel.
  • Implement operators and regular users.
  • Implement the commands that are specific to operators.

MacOS only

• Since MacOS doesn't implement write() the same way as other Unix OSes, the fcntl() should be used.
• The implementation of fcntl should be like fcntl(fd, F_SETFL, O_NONBLOCK), any other flag is forbidden.

Tests

• Verify absolutely every possible error and issue (recieving partial data, low bandwidth, and so forth).
• To ensure that the server correctly processes everything that we send to it, the following test could be used.

$ nc 127.0.0.1 <port>
com^Dman^Dd
$

• Use ctrl+D to send the command in several parts: 'com', then 'man', then 'd\n'.
• In order to process a command, aggregate (COLLECT) the received packets in order to rebuild it.

Bonus

• Handle file transfer.
• A bot.
