Vulcanize DB

Dependencies

Go 1.9+
Postgres 10
Go Ethereum
- https://ethereum.github.io/go-ethereum/downloads/

Installation

go get github.com/vulcanize/vulcanizedb

Setting up the Databases

Install Postgres
Create a superuser for yourself and make sure psql --list works without prompting for a password.
createdb vulcanize_private
cd $GOPATH/src/github.com/vulcanize/vulcanizedb
Import the schema: psql vulcanize_private < db/schema.sql

or run the migrations: make migrate HOST_NAME=localhost NAME=vulcanize_public PORT=5432
- See below for configuring additional environments

IPC File Paths

The default location for Ethereum is:

$HOME/Library/Ethereum for Mac
$HOME/.ethereum for Ubuntu
$GOPATH/src/gihub.com/vulcanize/vulcanizedb/test_data_dir/geth.ipc for private node.

Note the location of the ipc file is printed to the console when you start geth. It is needed to for configuration

Start syncing with postgres

Start geth node (if fast syncing wait for geth to finsh initial sync)
In a separate terminal start vulcanize_db
- vulcanizedb sync --config <config.toml> --starting-block-number <block-number>
- see ./environments for example config

Running the Tests

Unit Tests

go test ./pkg/...

Integration Test

In order to run the integration tests, you will need to run them against a real node. At the moment the integration tests require Geth v1.7.2 as they depend on the --dev mode, which changed in v1.7.3

Run make startprivate in a separate terminal
Setup a test database and import the schema:

createdb vulcanize_private

psql vulcanize_private < db/schema.sql
go test ./... to run all tests.
