Development

Dependencies

Supported build environments

Environment setup

If you have basic build tools like make already installed, you can run:

make deps

If you are starting from a fresh linux install with nothing, run:

./scripts/installDeps.sh

make deps

Testing

First run:

make build

This will build everything you need, including the sqlite extensions if they have not yet been built.

Entire suite

make test

One off tests

goTest.sh is a convenience script that sets up all relevant environment variables and runs the tests.

./scripts/goTest.sh -v ./internal/types/numbers -v -p 1 -run '^Test_Numbers$'

Long-running Rewards tests

The rewards tests are time and resource intensive and are not enabled to run by default.

Download the test data

./scripts/downloadTestData.sh testnet-reduced

Run the rewards tests

REWARDS_TEST_CONTEXT=testnet-reduced TEST_REWARDS=true ./scripts/goTest.sh -timeout 0 ./pkg/rewards -v -p 1 -run '^Test_Rewards$'

Options:

Build

This will build the go binary and the associated sqlite3 extensions:

make deps

make build

Bring Your Own PostgreSQL database

See PostgreSQL Setup for instructions on setting up a PostgreSQL database.

Directly using Go

Assumes you have PosgresSQL running locally already

make build
./bin/sidecar run \
    --ethereum.rpc-url="http://34.229.43.36:8545" \
    --chain="holesky" \
    --statsd.url="localhost:8125" \
    --database.host="localhost" \
    --database.port="5432" \
    --database.user="sidecar" \
    --database.password="..." \
    --database.db_name="sidecar"

# OR with go run
go run main.go run \
    --ethereum.rpc-url="http://34.229.43.36:8545" \
    --chain="holesky" \
    --statsd.url="localhost:8125" \
    --database.host="localhost" \
    --database.port="5432" \
    --database.user="sidecar" \
    --database.password="..." \
    --database.db_name="sidecar"

Using the public Docker container

Assumes you have PosgresSQL running locally already

docker run -it --rm \
  -e SIDECAR_DEBUG=false \
  -e SIDECAR_ETHEREUM_RPC_URL="http://34.229.43.36:8545" \
  -e SIDECAR_CHAIN="holesky" \
  -e SIDECAR_STATSD_URL="localhost:8125" \
  -e SIDECAR_DATABASE_HOST="localhost" \
  -e SIDECAR_DATABASE_PORT="5432" \
  -e SIDECAR_DATABASE_USER="sidecar" \
  -e SIDECAR_DATABASE_PASSWORD="..." \
  -e SIDECAR_DATABASE_DB_NAME="sidecar" \
  --tty -i \
  public.ecr.aws/z6g0f8n7/go-sidecar:latest run

Build and run a container locally

Assumes you have PosgresSQL running locally already

make docker-buildx-self

docker run \
  -e "SIDECAR_DEBUG=false" \
  -e "SIDECAR_ETHEREUM_RPC_URL=http://34.229.43.36:8545" \
  -e "SIDECAR_CHAIN=holesky" \
  -e "SIDECAR_STATSD_URL=localhost:8125" \
  -e SIDECAR_DATABASE_HOST="localhost" \
  -e SIDECAR_DATABASE_PORT="5432" \
  -e SIDECAR_DATABASE_USER="sidecar" \
  -e SIDECAR_DATABASE_PASSWORD="..." \
  -e SIDECAR_DATABASE_DB_NAME="sidecar" \
  --tty -i \
  go-sidecar:latest run

Running with docker-compose

By default, this will build the sidecar locally with Docker and run it.

If you wish to use the pre-built image, uncomment the image property in the sidecar service in docker-compose.yml and remove the build section

services:
  sidecar:
    image: public.ecr.aws/z6g0f8n7/sidecar:latest run
    #build:
    #  context: .
    #  dockerfile: Dockerfile
POSTGRES_DATA_PATH=<path to store postgres data> docker-compose up
