Rob Mulholand 3e39ccb9bb Fix missing block numbers lookup
- Previously, a block was treated as missing if there was a number in
the given range for which there existing a block that did not match
the node's fingerprint. This meant that in a case where we have a block
that does not match the node's fingerprint and also one that does match,
the block would be treated as missing. This led to errors being thrown
when attempting to add a block that already exists.
- These changes treat a block as missing only if we do not already have
a block that matches the number and node fingerprint.

Vulcanize DB

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.
