Go implementation of the Hermez node.

## Test

- First run a docker instance of the PostgresSQL (where `yourpasswordhere` should be your password)

```
POSTGRES_PASS=yourpasswordhere; sudo docker run --rm --name hermez-db-test -p 5432:5432 -e POSTGRES_DB=history -e POSTGRES_USER=hermez -e POSTGRES_PASSWORD="$POSTGRES_PASS" -d postgres && sleep 2s && sudo docker exec hermez-db-test psql -a history -U hermez -c "CREATE DATABASE l2;"
```

- Then, run the tests with the password as env var

```
POSTGRES_PASS=yourpasswordhere ETHCLIENT_DIAL_URL=yourethereumurlhere go test -p 1 ./...
```

NOTE: `-p 1` forces execution of package test in serial.  Otherwise they may be
executed in paralel and the test may find unexpected entries in the SQL
databse because it's shared among all tests.

## Lint

- Install [golangci-lint](https://golangci-lint.run)
- Once installed, to check the lints

```
golangci-lint run --timeout=5m -E whitespace -E gosec -E gci -E misspell -E gomnd -E gofmt -E goimports -E golint --exclude-use-default=false --max-same-issues 0
```
