upload_app

Flask-based web app with register/login capabilities where users upload their C/C++/Pascal/Java sources to be asynchronously tested by the app with the results returned to them live. Current mode tests using predefined input files.

Getting Started

These instructions will get you a copy of the project up and running on your local machine for development and testing purposes.

Docker version update

Just run start_all.sh. It should bring up nodes one by one in the right order to avoid race conflicts. You may also want to modify or get rid of nginx entirely for testing purposes.

All logic resides in a single Python source file, so if you value your sanity don't go near it. I never got to properly rewrite it. One day, maybe.

Prerequisites

• Python 2.7 (not tested on 3)
• pip
• Redis
• CouchDB
• gcc/g++/fpc/javac (depending on what you want to compile)

Besides packages installed with pip, you also need Redis and CouchDB installed on your system. A quick guide to install Redis can be found here, while CouchDB can be installed from here. They may also be available in your preferred distribution's package manager.

Installing and running

Clone the repo

mkdir app/upload_app/run/build

Wrap sources in a virtualenv for easier package management.

virtualenv .venv
source ./.venv/bin/activate

Install the required packages

pip install -r requirements.txt

Export flask needed global variables, run helper script to create database and views in CouchDB, then run flask app.

upload_app$ export FLASK_APP=upload_app
upload_app$ export FLASK_DEBUG=1
upload_app$ python upload_app/setup_db.py
upload_app$ flask run

Run a celery worker instance to be able to test uploaded files

upload_app$ celery worker -A upload_app.upload_app.celery --loglevel=info

Running a test

Assuming you already created and logged in to your account, to run a quick test just upload tests/kfib/implementations/kfib.cpp to the web app, then click on Begin test.
