Anubis

An online judge platform.

Prerequisites

Install requirements

In the root of the repository, where Pipfile and package.json locates:

pipenv install  # You may have to install pipenv
npm install   # cnpm install

You don't need root privilege to run npm install. It installs stuffs in the project directory.

You may want to use cnpm and tuna if you are in China. Make sure to use cnpm by adding alias to npm instead of installing cnpm cli-tool.

Some requirements may need Python.h. In Ubuntu/Debian simply use

apt install python3-dev

to solve the problem.

IP Geo-Location

To enable IP geo-location translation, you need to obtain a MaxMind GeoLite City DB and put it in the project root directory:

curl "http://geolite.maxmind.com/download/geoip/database/GeoLite2-City.mmdb.gz" | gunzip -c > GeoLite2-City.mmdb

You may also want to install libmaxminddb for higher performance.

Development

In the root of the repository:

npm run generate
npm run build   # or: npm run build:watch
python3 -m anubis.server --debug

Set --listen (default: http://127.0.0.1:8888) to listen on a different address.

As an intuitive example, you may want to add a super administator and a problem to start:

alias pm="python3 -m"
pm anubis.model.user add 1 admin 12345 [email protected]
pm anubis.model.user set_superadmin 1
pm anubis.model.adaptor.problem add system "Dummy Problem" "# It *works*" -1 1000   # you can also use web UI

Watch and Restart

Frontend source codes can be recompiled automatically by running:

npm run build:watch

However you need to manually restart the server for server-side code to take effect.

Production

npm run build:production
python3 -m anubis.server --listen=unix:/var/run/anubis.sock
  • Set --listen (default: http://127.0.0.1:8888) to listen on a different address.
  • Set --prefork (default: 1) to specify the number of worker processes.
  • Set --ip-header (default: '') to use IP address in request headers.
  • Set --url-prefix (default: http://acm.sut.edu.cn) to set URL prefix.
  • Set --cdn-prefix (default: /) to set CDN prefix.
  • Set --smtp-host, --smtp-user and --smtp-password to specify a SMTP server.
  • Set --db-host (default: localhost) and/or --db-name (default: test) to use a different database.

Better to use a reverse proxy like Nginx or h2o.

Judging

To enable Anubis to judge, at least one judge user and one judge daemon instance are needed.

  • Use following commands to create a judge user:
alias pm="python3 -m"
pm anubis.model.user add 2 judge 123456 [email protected]
pm anubis.model.user set_judge 2
  • See YamaJudge for more details about the judge daemon.
