Vulcanize DB

Build Status

Development Setup

Dependencies

Cloning the Repository

  1. git config --global url."git@github.com:".insteadOf "https://github.com/"
    • By default, go get does not work for private GitHub repos. This will fix that.
  2. go get github.com/8thlight/vulcanizedb
  3. cd $GOPATH/src/github.com/8thlight/vulcanizedb
  4. dep ensure

Setting up the Databases

  1. Install Postgres
  2. Create a superuser for yourself and make sure psql --list works without prompting for a password.
  3. createdb vulcanize_private
  4. cd $GOPATH/src/github.com/8thlight/vulcanizedb
  5. HOST_NAME=localhost NAME=vulcanize_public PORT=5432 make migrate
    • See below for configuring additional environments

Adding a new migration: ./scripts/create_migration <migration-name>

Building

  1. make build

Creating/Using a Private Blockchain

Syncing the public blockchain takes many hours for the initial sync and will download 20+ GB of data. Here are some instructions for creating a private blockchain that does not depend on having a network connection.

  1. Run ./scripts/setup to create a private blockchain with a new account.
    • This will result in a warning.
  2. Run ./scripts/start_private_blockchain.
  3. Run godo run -- --environment=private to start listener.

Connecting to the Public Blockchain

./scripts/start_blockchain

IPC File Paths

The default location for Ethereum is:

  • $HOME/Library/Ethereum for Mac
  • $HOME/.ethereum for Ubuntu
  • $GOPATH/src/gihub.com/8thlight/vulcanizedb/test_data_dir/geth.ipc for private blockchain.

Note the location of the ipc file is outputted when you connect to geth. It is needed to for configuration

Start Vulcanize DB

  1. Start geth
  2. In a separate terminal start vulcanize_db
    • vulcanize sync --config <config.toml> --starting-block-number <block-numbe>

Watch contract events

  1. Start geth
  2. In a separate terminal start vulcanize_db
    • vulcanize sync --config <config.toml> --starting-block-number <block-numbe>
  3. Create event filter
    • vulcanize addFilter --config <config.toml> --filter-filepath <filter.json>

Configuring Additional Environments

You can create configuration files for additional environments.

  • Among other things, it will require the IPC file path
  • See environments/private.toml for an example
  • You will need to do this if you want to run a node connecting to the public blockchain

Running the Tests

Unit Tests

  1. go test ./pkg/...

Integration Test

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

  1. Run ./scripts/start_private_blockchain as a separate process.
  2. go test ./... to run all tests.
