Vulcanize DB
About
Vulcanize DB is a set of tools that make it easier for developers to write application-specific indexes and caches for dapps built on Ethereum.
Dependencies
- Go 1.9+
- Postgres 10
- Ethereum Node
- Go Ethereum (1.8+)
- Parity 1.8.11+
Project Setup
Using Vulcanize for the first time requires several steps be done in order to allow use of the software. The following instructions will offer a guide through the steps of the process:
- Fetching the project
- Installing dependencies
- Configuring shell environment
- Database setup
- Configuring synced Ethereum node integration
- Data syncing
Installation
In order to fetch the project codebase for local use or modification, install it to your GOPATH
via:
go get github.com/vulcanize/vulcanizedb
Once fetched, dependencies can be installed via go get
or (the preferred method) at specific versions via golang/dep
, the prototype golang pakcage manager. Installation instructions are here.
In order to install packages with dep
, ensure you are in the project directory now within your GOPATH
(default location is ~/go/src/github.com/vulcanize/vulcanizedb/
) and run:
dep ensure
After dep
finishes, dependencies should be installed within your GOPATH
at the versions specified in Gopkg.toml
.
Lastly, ensure that GOPATH
is defined in your shell. If necessary, GOPATH
can be set in ~/.bashrc
or ~/.bash_profile
, depending upon your system. It can be additionally helpful to add $GOPATH/bin
to your shell's $PATH
.
Setting up the Database
-
Install Postgres
-
Create a superuser for yourself and make sure
psql --list
works without prompting for a password. -
Execute
createdb vulcanize_public
-
Execute
cd $GOPATH/src/github.com/vulcanize/vulcanizedb
-
Run the migrations:
make migrate HOST_NAME=localhost NAME=vulcanize_public PORT=<postgres port, default 5432>
- See below for configuring additional environments
In some cases (such as recent Ubuntu systems), it may be necessary to overcome failures of password authentication from localhost
. To allow access on Ubuntu, set localhost connections via hostname, ipv4, and ipv6 from peer
/md5
to trust
in: /etc/postgresql/<version>/pg_hba.conf
(It should be noted that trusted auth should only be enabled on systems without sensitive data in them: development and local test databases.)
Configuring Ethereum Node Integration
-
To use a local Ethereum node, copy
environments/public.toml.example
toenvironments/public.toml
and update theipcPath
andlevelDbPath
.-
ipcPath
should match the local node's IPC filepath:-
For 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:
<full home path>/Library/Ethereum
- Linux:
<full home path>/ethereum/geth.ipc
- Mac:
- The IPC file is called
-
For Parity:
- The IPC file is called
jsonrpc.ipc
. - The default location is:
- Mac:
<full home path>/Library/Application\ Support/io.parity.ethereum/
- Linux:
<full home path>/local/share/io.parity.ethereum/
- Mac:
- The IPC file is called
-
-
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:
<full home path>/Library/Ethereum/geth/chaindata
- Linux:
<full home path>/ethereum/geth/chaindata
- Mac:
levelDbPath
is irrelevant (andcoldImport
is currently unavailable) if only running parity.
-
-
See
environments/infura.toml
to configure commands to run against infura, if a local node is unavailable. (Support is currently experimental, at this time.)
Start syncing with postgres
Syncs VulcanizeDB with the configured Ethereum node.
- Start the node
- If node state is not yet fully synced, Vulcanize will not be able to operate on the fetched data. You will need to wait for the initial sync to finish.
- Start the vulcanize_db sync
- Execute
./vulcanizedb sync --config <path to config.toml>
- Or to sync from a specific block:
./vulcanizedb sync --config <config.toml> --starting-block-number <block-number>
- Execute
Alternatively, sync from Geth's underlying LevelDB
Sync VulcanizeDB from the LevelDB underlying a Geth node.
- Assure node is not running, and that it has synced to the desired block height.
- Start vulcanize_db
./vulcanizedb coldImport --config <config.toml>
- Optional flags:
--starting-block-number <block number>
/-s <block number>
: block number to start syncing from--ending-block-number <block number>
/-e <block number>
: block number to sync to--all
/-a
: sync all missing blocks
Running the Tests
In order to run the full test suite, a test database must be prepared. By default, the rests use a database named vulcanize_private
. Create the database in Postgres, and run migrations on the new database in preparation for executing tests:
make migrate HOST_NAME=localhost NAME=vulcanize_private PORT=<postgres port, default 5432>
Ginkgo is declared as a dep
package test execution. Linting and tests can be run together via a provided make
task:
make test
Tests can be run directly via Ginkgo in the project's root directory:
ginkgo -r
Start full environment in docker by single command
Geth Rinkeby
make command | description |
---|---|
rinkeby_env_up | start geth, postgres and rolling migrations, after migrations done starting vulcanizedb container |
rinkeby_env_deploy | build and run vulcanizedb container in rinkeby environment |
rinkeby_env_migrate | build and run rinkeby env migrations |
rinkeby_env_down | stop and remove all rinkeby env containers |
Success run of the VulcanizeDB container require full geth state sync, attach to geth console and check sync state:
$ docker exec -it rinkeby_vulcanizedb_geth geth --rinkeby attach
...
> eth.syncing
false
If you have full rinkeby chaindata you can move it to rinkeby_vulcanizedb_geth_data
docker volume to skip long wait of sync.
