Codecov API

We believe that everyone should have access to quality software (like Sentry), that’s why we have always offered Codecov for free to open source maintainers.

By making our code public, we’re not only joining the community that’s supported us from the start — but also want to make sure that every developer can contribute to and build on the Codecov experience.

A private Django REST Framework API intended to serve Codecov's front end.

Getting Started

Building

This project contains a makefile. To build the docker image:

make build

requirements.txt is used in the base image. If you make changes to requirements.txt you will need to rebuild.

Note, you'll need to install Rust to build ribs which is a dependency of shared. Go here for more info on how to do this: https://www.rust-lang.org/tools/install

Running Standalone

This project contains a docker-compose.yml file that is intended to run the api standalone. In this configuration it does not share codecov.io's development database; so don't expect parity there.

To start the service, do

docker-compose up

Utilizing its own database provides a convenient way for the REST API to provide its own helpful seeds and migrations for active development without potentially destroying/modifying your development database for codecov.io.

Once running, the api will be available at http://localhost:5100

Running with codecov.io

This service will startup when you run codecov.io normally. It is under that api block of codecov.io's docker-compose.yml file.

Testing

The easiest way to run tests (that doesn't require installing postgres and other dependencies) is to run inside of docker:

docker-compose up
docker exec -it codecov-api_api_1 pytest -rf

Testing standalone

If you would like to use pytest directly (Either through an IDE like PyCharm or with the CLI), you will need to change the settings file used by pytest. Run this command to have the tests executed (You will need an instance of postgres running locally):

RUN_ENV=TESTING DJANGO_SETTINGS_MODULE=codecov.settings_test pytest

Make sure to have all the requirements from requirements.txt installed.

Deploying

All work merged into the main branch is immediately deployed to the production environment. More context on this strategy can be found here.

Deploying to Staging environment

To deploy to our staging environment it's crucial to follow these steps:

1. Check in Slack to see if anyone is currently using the staging environment
2. If not, delete the current staging branch
3. Create a new staging branch and merge your feature branch into it

Steps 2 and 3 are important to limit interaction between features not yet merged into main. This approach was inspired by this document: https://codecovio.atlassian.net/wiki/spaces/ENG/pages/507445249/Branching+and+Continuous+Delivery+Strategy+Proposal

Secret and Credential Management

This project should store no secrets or credentials in its source. If you need to add to / modify / setup secrets for this project, contact Eli and he'll get you started..

Adding dependencies

This repository uses pip-tools to manage dependencies, so make sure you've installed it with pip install pip-tools. To add or update dependencies, change requirements.in, Then run

pip-compile requirements.in

Do not change requirements.txt directly.

Formatting

This project uses black for formatting.
You can run the linter using the command make lint.

Migrations

We leverage Django's migration system to keep the state of our models in sync with the state of our database. You can read more about how we work with migrations at https://codecovio.atlassian.net/wiki/spaces/ENG/pages/1696530442/Migrations
