|
|
|
|
### 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
|
|
|
|
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/vulcanize/vulcanizedb`
|
|
5. 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
|
|
|
|
Adding a new migration: `./scripts/create_migration <migration-name>`
|
|
|
|
## Start syncing with postgres
|
|
1. Start geth
|
|
2. In a separate terminal start vulcanize_db
|
|
- `vulcanizedb sync --config <config.toml> --starting-block-number <block-numbe>`
|
|
|
|
* see `environments` for example config
|
|
|
|
## Watch specific contract events
|
|
1. Start geth
|
|
2. In a separate terminal start vulcanize_db
|
|
- `vulcanizedb sync --config <config.toml> --starting-block-number <block-numbe>`
|
|
3. Create event filter
|
|
- `vulcanizedb addFilter --config <config.toml> --filter-filepath <filter.json>`
|
|
|
|
* see `filters` for example filter
|
|
|
|
## Development Setup
|
|
|
|
### Cloning the Repository (Private repo only)
|
|
|
|
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/vulcanize/vulcanizedb`
|
|
3. `cd $GOPATH/src/github.com/vulcanize/vulcanizedb`
|
|
4. `dep ensure`
|
|
|
|
### Creating/Using a test node
|
|
|
|
Syncing the against the public network takes many hours for the initial sync and will download 20+ GB of data.
|
|
Here are some instructions for creating a private test node that does not depend on having a network connection.
|
|
|
|
1. Run `./scripts/setup` to create a private blockchain with a new account.
|
|
* This will result in a warning.
|
|
2. Run `./scripts/start_private_blockchain`.
|
|
|
|
### IPC File Paths
|
|
|
|
The default location for Ethereum is:
|
|
- `$HOME/Library/Ethereum` for Mac
|
|
- `$HOME/.ethereum` for Ubuntu
|
|
- `$GOPATH/src/gihub.com/vulcanize/vulcanizedb/test_data_dir/geth.ipc` for private blockchain.
|
|
|
|
**Note the location of the ipc file is printed to the console when you start geth. It is needed to for configuration**
|
|
|
|
## 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](https://ethereum.github.io/go-ethereum/downloads/) 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.
