Build Status

Dependencies

Installation

go get github.com/vulcanize/vulcanizedb

Setting up the Database

  1. Install Postgres

  2. Create a superuser for yourself and make sure psql --list works without prompting for a password.

  3. createdb vulcanize_public

  4. cd $GOPATH/src/github.com/vulcanize/vulcanizedb

  5. Run the migrations: make migrate HOST_NAME=localhost NAME=vulcanize_public PORT=5432

    • See below for configuring additional environments

Configuration

  • To use a local Ethereum node, copy environments/public.toml.example to environments/public.toml and update the ipcPath and levelDbPath.

    • ipcPath should match the local node's IPC filepath:

      • when using geth:

        • The IPC file is called geth.ipc.
        • The geth IPC file path is printed to the console when you start geth.
        • The default location is:
          • Mac: $HOME/Library/Ethereum
          • Linux: $HOME/.ethereum
      • when using parity:

        • The IPC file is called jsonrpc.ipc.
        • The default location is:
          • Mac: $HOME/Library/Application\ Support/io.parity.ethereum/
          • Linux: $HOME/.local/share/io.parity.ethereum/
    • levelDbPath should match Geth's chaindata directory path.

      • The geth LevelDB chaindata path is printed to the console when you start geth.
      • The default location is:
        • Mac: $HOME/Library/Ethereum/geth/chaindata
        • Linux: $HOME/.ethereum/geth/chaindata
      • levelDbPath is irrelevant (and coldImport is currently unavailable) if only running parity.
  • See environments/infura.toml to configure commands to run against infura, if a local node is unavailable

Start syncing with postgres

Syncs VulcanizeDB with the configured Ethereum node.

  1. Start node (if fast syncing wait for initial sync to finish)
  2. In a separate terminal start vulcanize_db
    • ./vulcanizedb sync --config <config.toml> --starting-block-number <block-number>

Alternatively, sync from Geth's underlying LevelDB

Sync VulcanizeDB from the LevelDB underlying a Geth node.

  1. Assure node is not running, and that it has synced to the desired block height.
  2. Start vulcanize_db
    • ./vulcanizedb coldImport --config <config.toml> --starting-block-number <block-number> --ending-block-number <block-number>
  3. Optional flags:
    • --starting-block-number/-s: block number to start syncing from
    • --ending-block-number/-e: block number to sync to
    • --all/-a: sync all missing blocks

Running the Tests

Unit Tests

  • go test ./pkg/...

Integration Tests

  • go test ./... to run all tests.
