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. go get github.com/ethereum/go-ethereum
    • This will take a while and gives poor indication of progress.
  4. go install github.com/ethereum/go-ethereum/cmd/geth
  5. cd $GOPATH/src/github.com/8thlight/vulcanizedb
  6. 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. go get -u -d github.com/mattes/migrate/cli github.com/lib/pq
  4. go build -tags 'postgres' -o /usr/local/bin/migrate github.com/mattes/migrate/cli
  5. createdb vulcanize_public
  6. createdb vulcanize_private
  7. cd $GOPATH/src/github.com/8thlight/vulcanizedb
  8. godo migratePublic
  9. godo migratePrivate

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

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.

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 a blockchain. It is needed to start the listener below

Running Listener

  1. Start a blockchain.
  2. In a separate terminal start listener (ipcDir location)
    • godo runPublic -- --ipc-path /path/to/file.ipc

Running the Tests

Integration Test

In order to run the integration tests, you will need to run them against a real blockchain.

  1. Run ./scripts/start_private_blockchain as a separate process.
  2. go test ./...

Unit Tests

  1. go test ./core
