Deployment
==========

Install the following packages:

  - apache2
  - python3-falcon
  - python3-ply
  - python3-psycopg2
  - python3-termcolor
  - python3-waitress
  - swi-prolog-nox

Settings:

  - point webroot to codeq-web
  - set up reverse proxy for /svc/ to wsgi server:
      ProxyPass /svc/ http://localhost:8082/
      ProxyPassReverse /svc/ http://localhost:8082/
  - set _path_prefix in server.problems
  - set DB settings in db

Running:

  - run prolog/runner/main.pl
  - run python/runner/main.py
  - run daemon.py
  - run wsgi_server.py

Misc.
=====

Add a new problem to the database by running

    python -m scripts.add_problem

in the toplevel directory. This will ask for language and problem group (groups
can be shared between languages, e.g. Introduction can be used for both Prolog
and Python). The script will print the ID and path for the new problem.

You can test stuff in a python interpreter:

    >>> import server
    >>> session = server.user_session.authenticate_and_create_session(<user>, <pass>)
    >>> session.get_problem_data('python', 'introduction', 'fahrenheit_to_celsius')

    >>> python = session.get_python()
    >>> python.test(231, 180, '''print('-17.7')''')
    >>> python.hint(231, 180, '''print('-17.7')''')

    >>> prolog = session.get_prolog()
    >>> prolog.test(231, 96, 'sister(X,Y):- parent(P,X), parent(P,Y), female(X).')
    >>> prolog.hint(231, 96, 'sister(X,Y):- parent(P,X), parent(P,Y), female(X).')
