distributed-chat

This program will implement distributed chat on virtual ring topology network. Furthermore this program will implement Chang-Roberts algorithm to achieve full ordering of messages.

Features:

• Nodes can freely join into existing ring, based on information about one node (IP:port). First node will join with itself into ring.
• Ring will recover from unexpected disconnect of one node at the time.
• One node will be elected as central authority (leader), all messages will be then passed through leader.
• Leader will be elected using Chang-Roberts algorithm.
• GUI in Qt, it will also have CLI.
• Encryption of messages.

How to build documentation

1. Create virtual environment using: python3.5 -m venv env
2. Activate virtual environment: . env/bin/activate
3. Install dependencies: python -m pip install -r requirements.txt
4. Change directory into docs: cd docs
5. Build documentation: make html
6. Open file docs/_build/html/index.html to view documentation.

How to run tests

Run (in installed and activated virtual environment):

python setup.py test

or

pytest -v tests/test_chat.py
