Divide and map. Now. -- the damn project -- helps mappers by dividing a big area into smaller squares that people can map together.

damn_server provides access to the PostGIS database via JSON API. It is written in Python3 and published under AGPLv3 License.

Report security issues. Send patches to:

git config format.subjectPrefix 'PATCH damn-server'
git config sendemail.to '~qeef/damn-dev@lists.sr.ht'

To develop, you need PostGIS database. You can use damn-deploy:

git clone https://git.sr.ht/~qeef/damn-deploy
cd damn-deploy
sed -i '/POSTGRES_PASSWORD=.*/d' .env
docker-compose -f http.yml up db

Create virtual environment and install dependencies:

python3 -m venv tve
. tve/bin/activate
pip install -r requirements.dev.txt

Set environment variable with the IP address of the damndb:

export DB_HOST=$(docker inspect -f '{{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}' damndb)

Run unit tests:

python3 -m unittest discover tests

with coverage:

coverage run --branch --include=damn_server/area.py,damn_server/conf.py,damn_server/db.py,damn_server/list_of.py,damn_server/new.py,damn_server/square.py,damn_server/user.py,damn_upkeep/execute.py,damn_upkeep/generate.py -m unittest discover tests && coverage report

Run damn server app:

uvicorn damn_server.api:app --workers 9

Run integration tests (damn server app must be running):

python3 -m unittest tests/integration.py

NOTE: You can prepend python3 or uvicorn with PYTHONASYNCIODEBUG=1 to see the async debug info.

NOTE: Use --workers 9 for testing. When developing, use --reload instead.

Run load tests (damn server app must be running):

pip install -r requirements.loadtest.txt
locust -f tests/mapathon.py -H http://127.0.0.1:8000 -u 1000 -r 10 -t 10m --headless --only-summary

Connect to the database:

psql "postgresql://damnuser:$(cat .env | sed -n 's/^POSTGRES_PASSWORD=\(.\+\)$/\1/p')@$(docker inspect -f '{{range.NetworkSettings.Networks}}{{.IPAddress}}{{end}}' damndb)/damndb"

Make documentation:

pip install -r requirements.doc.txt
cd doc && make html
