As a fork of DMOJ, VNOJ serves as VNOI's official online judge and hosts its programming contests.

See it live at oj.vnoi.info!

Check out its features here.

Refer to the install documentation here. Almost all installation steps remain the same as the docs, but there are several minor differences, including cloning this repo instead of DMOJ's repo.

• You have to define DMOJ_PROBLEM_DATA_ROOT in local_settings.py, which should be the path to the directory that contains your problems' tests.

• Regarding disabling full-text search, please read this issue for more information.

• To sync the judge server and the site's cache, change the cache framework (CACHES) to memcached or redis instead of the default (local-memory caching).

• If you use python3 manage.py loaddata demo, the home button in the admin dashboard (/admin) links you to localhost:8081, there are 2 ways to change that:

  1. You can change that in demo.json
  2. You can go to the admin page, scroll down to find the Sites setting and change localhost:8081 to your domain.

• To support testlib.h, you need to copy testlib.h to g++'s include path in the judge server. To speed up compile time, you can also create a precompiled header for testlib.h.
