datachat's Issues

Logging

All chat and messages should be written to a text file. The filename should be built from the current date, time, and user name, and the logs should be stored in a subdirectory called "logs".

Some ! commands are not working

Use Message class instead of strings.

Error Checking

The system should implement error checking algorithms to verify message integrity. The project description mentions Simple Parity Check, Two-dimensional Parity check, Checksum and Cyclic Redundancy Check (CRC).

Only use the implementations Simple Parity Check and Cyclic Redundancy Check (CRC).

Error checking methods

Update message structure.

sender username | Command Type | content | [Checking bits (Method 1)] [Checking bits (Method 2)]

Method1 = Parity Bity
Method2 = CRC

Validation for ! commands

TCP Streaming/Segmentation issue

There’s a problem that when you send multiple messages to the client, they receive it as a single message.

This is a common issue with TCP, which is a stream-based protocol and does not guarantee that messages will arrive as sent. Instead, TCP guarantees that all bytes will arrive in the order they were sent.

This means that if we send two messages, "Hello" and "World", it's possible that the client will receive them as a single message, "HelloWorld". It causes an error while checking parity bits.

To handle this, implement a message framing protocol on top of TCP. One common method is to prefix each message with its length.
