|
|
|
|
[](https://travis-ci.org/vulcanize/VulcanizeDB)
|
|
|
|
### 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 $GOPATH/src/github.com/vulcanize/vulcanizedb`
|
|
5. Import the schema: `psql vulcanize_private < db/schema.sql`
|
|
|
|
or run the migrations: `make migrate HOST_NAME=localhost NAME=vulcanize_public PORT=5432`
|
|
* See below for configuring additional environments
|
|
|
|
### IPC File Paths
|
|
|
|
The default location for Ethereum is:
|
|
- `$HOME/Library/Ethereum` for Mac
|
|
- `$HOME/.ethereum` for Ubuntu
|
|
- `$GOPATH/src/gihub.com/vulcanize/vulcanizedb/test_data_dir/geth.ipc` for private node.
|
|
|
|
**Note the location of the ipc file is printed to the console when you start geth. It is needed to for configuration**
|
|
|
|
## Start syncing with postgres
|
|
1. Start geth node (**if fast syncing wait for geth to finsh initial sync**)
|
|
2. In a separate terminal start vulcanize_db
|
|
- `vulcanizedb sync --config <config.toml> --starting-block-number <block-number>`
|
|
|
|
* see `./environments` for example config
|
|
|
|
## Watch specific events
|
|
1. Start geth
|
|
2. In a separate terminal start vulcanize_db
|
|
- `vulcanizedb sync --config <config.toml> --starting-block-number <block-number>`
|
|
3. Create event filter
|
|
- `vulcanizedb addFilter --config <config.toml> --filter-filepath <filter.json>`
|
|
* see `./filters` for example filter
|
|
4. The filters are tracked in the `log_filters` table and the filtered events
|
|
will show up in the `watched_log_events` view
|
|
|
|
## 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 node. 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 `make startprivate` in a separate terminal
|
|
2. Setup a test database and import the schema:
|
|
|
|
`createdb vulcanize_private`
|
|
|
|
`psql vulcanize_private < db/schema.sql`
|
|
3. `go test ./...` to run all tests.
