Release v0.8.0: Add Robin API and Robin Client CLI

Robin Server

  • A new module which handles all cips with hashtags.
  • Cips and hashtags can be retrieved using timestamps as reference.
• Robin User
  • Add followers list into the user's data structure.

Release v0.6.2: minor bug fixes and improvements

Robin Server:

• Move cleanup code from signal handler to main
• Robin Thread:
  • use condition variable for RT state for increased versatility
• Robin User:
  • fix minor bug

Release v0.6.1: move socket library and new alloc_safe library under lib/

Robin Server: the lib/alloc_safe.h library makes the allocation and deallocation of resources safe against pthread_cancel called on SIGINT.
This is useful for Valgrind debug in order to correctly clean-up all the allocated resources.

Release v0.6.0: add Follow/Unfollow/Following commands and cleanup gracefully

Robin Server: can be debugged with Valgrind.

• Robin Connection:
  • All resources are allocated and freed safely with pthread_setcancelstate().
  • New available commands:
    • follow: pass users' email to follow
    • unfollow: pass users' email to unfollow
    • following: list all following users
• Robin User:
  • A list of following emails is kept in User Data.
  • TODO: make User Data persistent on the file system.
• Robin Threads:
  • Gracefully exit with pthread_cleanup_push/pop().

Robin API (TODO): C API for Robin clients.

Robin Client (TODO): A Robin CLI client.

Release v0.5.0: add Register/Login/Logout commands

Robin Server:

• Robin Connection: new layer which encapsulates old Robin Manager.
  • It setups a robin_conn_t structure (no robin_ctx_t anymore).
  • New available commands:
    • register: pass email and password to register
    • login: validate email and password to acquire user data
    • logout: release the user data
• Robin User: provide exclusive access to user data in memory using mutexes.
  • User data is volatile in memory. TODO: make it persistent on the file system.
  • Robin Threads acquire and release user data using Robin Connection layer functions.
  • User data locking is not blocking (pthread_mutex_trylock()) preventing the connection from stalling.

Robin API (TODO): C API for Robin clients.

Robin Client (TODO): A Robin CLI client.

Release v0.4.1: stable enough to publish release

Robin Server: creates a TCP socket bound to host and port passed as command-line arguments.
It dispatches the connected clients (the socket file descriptors) to the Robin Thread Pool.

• Robin Thread Pool: spawns N Robin Thread (RT) to serve connected clients, with N a compile-time constant.
  • The server can handle up to N connections at a time.
  • An RT waits blocked in a queue until the server dispatch a new socket file descriptor to the pool.
  • The waked up RT handle the connection using the Robin Manager.
• Robin Manager: handles the connection with the client associated with the running thread.
  • Set up a context in which all data related to the client is stored.
  • Parse the lines arriving from the socket to execute the requested commands.
  • Available commands:
    • help: return the command list
    • quit: close the connection

Robin API (TODO): C API for Robin clients.

Robin Client (TODO): A Robin CLI client.
