This is a copyright violation detector web tool for Wikipedia articles running on Wikimedia Cloud Services at copyvios.toolforge.org.

It can search the web for content similar to a given article, and graphically compare an article to specific URLs. Some technical details are expanded upon in a blog post, though much of it is outdated.

• If using Toolforge, clone the repository to ~/www/python/src, or otherwise symlink it to that directory.

• Create a virtual environment and install the dependencies. On Toolforge, this should be in ~/www/python/venv, otherwise it can be in a subdirectory of the git project named .venv:

  python3 -m venv .venv
  . .venv/bin/activate
  pip install -e .
  

• If you intend to modify CSS or JS, install the frontend dependencies:

  npm install -g uglify-js cssnano postcss postcss-cli
  

• Create an SQL database with the tables defined by schema.sql.

• Create an earwigbot instance in .earwigbot (run earwigbot .earwigbot). In .earwigbot/config.yml, fill out the connection info for the database by adding the following to the wiki section:

  copyvios:
    oauth:
      consumer_token: <oauth consumer token>
      consumer_secret: <oauth consumer secret>
    sql:
      engine: mysql
      host: <hostname of database server>
      db: <name of database>
  

• Run make to minify JS and CSS files after making any frontend changes.

• Start your WSGI server pointing to app:app. For production, uWSGI or Gunicorn are likely good options. For development, use flask run.
