The wp1 subdirectory includes code for updating the enwp10 database, specifically the ratings table (but also other tables). The library code itself isn't directly runnable, but instead is loaded and run in various docker images that are maintained in the docker directory.

requirements.txt is a list of python dependencies in pip format that need to be installed in a virtual env in order to run the library code. Both the web and workers docker images use the same requirements, though Flask and its dependencies are not utilized by the worker code.

The cron directory contains wrapper scripts for cron jobs that are run inside the workers image.

The setup directory contains a historical record of the database schema used by the tool for what is refered to in code as the wp10 database. This file has been heavily edited, but should be able to be used to re-create the enwp10 database if necessary.

wp1-frontend contains the code for the Vue-CLI based frontend, which is encapsulated and served from the frontend docker image. See that directory for instructions on how to setup a development environment for the frontend.

conf.json is a configuration file that is used by the wp1 library code.

docker-compose.yml is a file read by the docker-compose command in order to generate the graph of required docker images that represent the production environment.

docker-compose-dev.yml is a similar file which sets up a dev environment, with Redis and a MariaDB server for the enwp10 database. Use it like so

docker-compose -f docker-compose-dev.yml up -d

The *.dockerfile symlinks allow for each docker image in this repository to be more easily built on Docker Hub. See:

openapi.yml is a YAML file that describes the API of the web image in OpenAPI format. If you visit the index of the API server you will get a swagger-ui documentation frontend that utilizes this file. It is symlinked into the wp1/web directory.

The wp10_test.*.sql and wiki_test.*.sql files are rough approximations of the schemas of the two databases that the library interfaces with. They are used for unit testing.


This code is targeted to and tested on Python 3.9.4.

Creating your virtualenv

As of Python 3.3, creating a virtualenv is a single easy command. It is recommmended that you run this command in the top level directory:

python3 -m venv venv

Activating your virtualenv

To activate your virtualenv, run:

source venv/bin/activate

You should see your prompt change, with a (venv) appended to the front.

Installing requirements

To install the requirements, make sure you are in your virtualenv as explained above, then use the following command:

pip3 install -r requirements.txt

Installing frontend requirements

To install the requirements for the frontend server, cd into wp1-frontend and use:

yarn install


You will also need to have Docker on your system in order to run the development server.

Running the tests

The tests expect a localhost MariaDB or MySQL instance on the default port, with a user of 'root' and no password. You also need two databases: enwp10_test and enwikip_test. They can use default settings and be empty.

If you have that, and you've already installed the requirements above, you should be able to simply run the following command from this directory to run the tests:


If you'd like to use a different MySQL user or non-default password for the tests, you must edit _setup_wp_one_db and _setup_wp_one_db in

Populating the credentials module

The script needs access to the enwiki_p replica database (referred to in the code as wikidb), as well as its own toolsdb application database (referred to in the code as wp10db). If you are a part of the toolforge enwp10 project, you can find the credentials for these on toolforge in the file in the tool's home directory. They need to be formatted in a way that is consumable by the library and pymysql. Look at and create a copy called with the relevant information filled in. The production version of this code also requires English Wikipedia API credentials for automatically editing and updating tables like this one. Currently, if your environment is DEVELOPMENT, jobs that utilize the API to edit Wikipedia are disabled. There is no development wiki that gets edited at this time.


For development, you will need to have Docker installed as explained above.

Running docker-compose

There is a Docker setup for a development database. It lives in docker-compose-dev.yml.

Before you run the docker-compose command below, you must copy the file wp1/ to wp1/ and fill out the section for STORAGE, if you wish to properly materialize builder lists into backend selections.

After that is done, use the following command to run the dev environment:

docker-compose -f docker-compose-dev.yml up -d

Migrating the dev database

The dev database will need to be migrated in the following circumstances:

  1. In a clean checkout, the first time you run the docker-compose command above.
  2. Anytime you remove/recreate the docker image
  3. Anytime you or a team member adds a new migration

To migrate, cd to the db/dev directory and run the following command:

yoyo apply

The YoYo Migrations application will read the data in db/dev/yoyo.ini and attempt to apply any necessary migrations to your database. If there are migrations to apply, you will be prompted to confirm. If there are none, there will be no output.

More information on YoYo Migrations is available here.

Starting the API server

Assuming you are in your Python virtualenv (described above) you can start the API server with:

FLASK_DEBUG=1 flask run

Starting the web frontend

The web frontend can be started with the following command in the wp1-frontend directory:

yarn serve


The DEVELOPMENT section of is already filled out with the proper values for the servers listed in docker-compose-dev.yml. You should be able to simply copy it to

If you wish to connect to a wiki replica database on toolforge, you will need to fill out your credentials in WIKIDB section. This is not required for developing the frontend.

Development overlay

The API server has a built-in development overlay, currently used for manual update endpoints. What this means is that the endpoints defined in are used with priority, instead of the production endpoints, only if the ENV == Environment.DEVELOPMENT. This is to allow for easier manual and CI testing of the manual update page.

If you wish to test the manual update job with a real Wikipedia replica database and RQ jobs, you will have to disable this overlay. The easiest way would be to change the following line in

  if ENV == environment.Environment.DEVELOPMENT:
    # In development, override some project endpoints, mostly manual
    # update, to provide an easier env for developing the frontend.
    print('DEVELOPMENT: overlaying dev_projects blueprint. '
          'Some endpoints will be replaced with development versions')
    app.register_blueprint(dev_projects, url_prefix='/v1/projects')

to something like:

  if false:  # false while manually testing
    # In development, override some project endpoints, mostly manual

Updating production

  • Since Docker Hub no longer auto builds images, you must build the images yourself. From the wp1 directory, run the following commands to build and push the images:
    • git checkout main
    • git pull origin main
    • ./
  • Log in to the box that contains the production docker images. It is called wp1.
  • cd /data/code/wp1/
  • sudo git pull origin main
  • Pull the docker images from docker hub:
    • docker pull openzim/wp1bot-workers
    • docker pull openzim/wp1bot-web
    • docker pull openzim/wp1bot-frontend
  • Run docker-compose to bring the production images online.
    • docker-compose up -d
  • Run the production database migrations in the worker container:
    • docker exec -ti wp1bot-workers yoyo -c /usr/src/app/db/production/yoyo.ini apply

Pre-commit hooks

This project is configured to use git pre-commit hooks managed by the Python program pre-commit (website). Pre- commit checks let us ensure that the code is properly formatted with yapf amongst other things.

If you've installed the requirements for this repository, the pre-commit binary should be available to you. To install the hooks, use:

pre-commit install

Then, when you try to commit a change that would fail pre-commit, you get:

(venv) host:wikimedia_wp1_bot audiodude$ git commit -am 'Test commit'
Trim Trailing Whitespace.................................................Passed
Fix End of Files.........................................................Passed
hookid: yapf

From there, the pre-commit hook will have modified and thus unstaged some or all of the files you were trying to commit. Look through the changes to make sure they are sane, then re-add them with git add, before trying your commit again.
