cmput379assignment2's Issues

Server switch function

if first char @, !, ? - do functions a, b, c

Implement Read Size

On client you need to read ONLY the length that is the size being sent. MESSY

Client side read parsing and logic

Refactor socket

Don't open and close every time -> take it out of the while

Client-side Write Sanitization

If no input: keep waiting.

If input: sanitize the formatting of the input and send message.

Server Store (Backend)

Server query (?) function

No message? -> return "no message" message (in assignment pdf)

Message -> return correct message (outlined in assignment pdf)

Interface

• The client must also give the user to exit orderly (e.g., typing an exit command) and to do the same (orderly exit) if it receives control-C

• The client should be callable as the following command: wbc379 hostname portnumber [keyfile]

• Upon an error condition, a client must be able to terminate as soon as possible when it detects the error (this could be an error in the protocol message it receives), closing the socket of the connection, informing the user about what happened, and exiting.

• The server should be callable as the following command: wbs379 portnumber {-f statefile | -n entries}

• It only (orderly) terminates when a SIGTERM message is sent to it. It is the handling of this SIGTERM that allows the server to dump the whiteboard contents to a file called whiteboard.all in the directory where it started its execution. After handling the SIGTERM, the server terminates. This whiteboard.all follows the format of the statefile. In fact, we should be able to start a previously terminated execution of the server using as statefile the whiteboard.all saved by the previous execution of the server.

Connection established message

Clean out main on both Server and Client
Connection established message

Server SWITCH and GET-MESSAGE function

Receive (read) text

Sanitize input (Logic)

MAIN TODO

• Client side write sanitization - connectAndTalk.c:75
• Server side logic - talk.c:63 (results in writing to socket)
• Client side read - connectAndTalk.c:85
• Connected message on client -
  .
• Server backend
  .
• Compile and run convoluted bs
