TurtleCoin Turtle-Service High-Availability Wrapper

This project is designed to wrap the turtle-service process on a *nix system and monitor it for hangups, locks, and etc that cause the wallet to stop responding.

The sample service.js includes a VERY basic example of how the wrapper can be used. For all options, please continue reading as it provides a VERY robust interface.

It also provides easy access to the turtle-service RPC API via native Javascript Promises.

To Do

  1. After the wallet container is synced, compare the wallet height to the network_height of the daemon (or public node) to detect if the wallet is out of sync.

Dependencies

Easy Start

You must copy turtle-service into the turtleservice-ha folder for the easy start process to occur.

git clone https://github.com/brandonlehmann/turtleservice-ha.git
cd turtleservice-ha
cp <turtle-service> .
./turtle-service -g -w container.walletd
npm install & node service.js

It is highly recommended that you create a container with a password and pass that into the wrapper. For your own security, please make sure that you use passwords for both the RPC server and the container itself. To do otherwise will fill you with regret.

Keep it Running

I'm a big fan of PM2 so if you don't have it installed, the setup is simple.

npm install -g pm2
 
pm2 startup
pm2 install pm2-logrotate
 
pm2 start service.js --watch --name turtleservice
pm2 save

Initialization

Practically all of the turtle-service command line arguments are exposed in the constructor method. Simply include them in your list of options to activate or use them. Default values are defined below. As always, please use values that make sense for your implementation.

There are a lot of different options available so reading through the full list is to your advantage.

Methods

wallet.start()

Starts turtle-service and starts monitoring the process.

wallet.start()

wallet.stop()

Stops turtle-service and halts all monitoring processes.

wallet.stop()

wallet.write(text)

If you really must write text to the actual turtle-service console, you can do so with this method. You'll need to parse the output of the data event as defined below.

wallet.write('help')

Events

Event - alive

This event is fired initially when the underlying turtle-service process is detected as being alive. It will also fire when it comes back alive after the process has been restarted. In addition, it will fire on the websocket connection after a successful authentication if the service is indeed alive.

wallet.on('alive', () => {
  // do something
})

Event - close

This event is fired when the underlying turtle-service process closes, dies, is killed for whatever reason. Usually, when this occurs we want to restart the process with wallet.start()

wallet.on('close', (exitcode) => {
  wallet.start()
})

Event - data

Provides the actual console output of turtle-service on a per line basis.

wallet.on('data', (data) => {
  // do something
})

Event - down

This event is fired when we detected that turtle-service appears down. It means that it is not responding to RPC requests. If you want to make it automatically restart turtle-service when this occurs, simply wallet.stop() in the event.

wallet.on('down', () => {
  wallet.stop()
})

Event - error

Provides the event for when an error event is encountered. These are bad, something isn't working right.

wallet.on('error', (err) => {
  // do something
})

Event - info

Provides the event for when an informational event is encountered.

wallet.on('info', (info) => {
  // do something
})

Event - save

This event is fired every save interval.

wallet.on('save', () => {
  // do something
})

Event - scan

This event is fired every scan interval to let us know that the service is currently scanning blocks for transactions that we need to handle.

wallet.on('scan', (fromBlock, toBlock) => {
  // do something
})

Event - status

This event is fired every polling cycle. It returns the equivalent of the turtle-service getStatus API call.

wallet.on('status', (status) => {
  // do something
})

Example Data

{
  "blockCount": 491136,
  "knownBlockCount": 491137,
  "lastBlockHash": "bc25f55db114fbe99720cb776b2c3b4787803edf1fb4cdd1851772087113b8eb",
  "peerCount": 8
}

Event - synced

This event is fired when turtle-service is fully synchronized with the network.

wallet.on('synced', () => {
  // do something
})

Event - transaction

This event is fired for each transaction that turtle-service says belongs to us. It contains the information for each transfer in the transaction rolled up into a single object for each transfer with one small addition of inbound which is a boolean. It will only fire for the portion(s) of the transaction where the transfer belong to the wallet container.

Special Note: Any and all amounts/fees will already be in HUMAN readable units. DO NOT DIVIDE THEM AGAIN unless you've specified decimalDivisor as 1 in the options. You have been warned.

wallet.on('transaction', (transaction) => {
  // do something very useful
})

Example Data

{
  "blockHash": "f98d6bbe80a81b3aa0aebd004096e2223524f58f347a1f21be122450f244b948",

  "amount": 10,
  "type": 0,
  "unlockTime": 0,
  "inbound": true
}

Event - warning

Provides the event for when a warning event is encountered. These are warnings saying that it might still work but you really should fix whatever the problem is.

wallet.on('warning', (warn) => {
 // do something
})

TurtleService RPC API Interface

As we can actually run this wrapper inside another nodeJS project, we expose all of the turtle-service RPC API commands via the wallet.api property. Each of the below methods are Javascript Promises. For safety sake, always handle your promise catches as we do use them properly.

Special Note: Any and all amounts/fees will already be in HUMAN readable units. DO NOT DIVIDE THEM AGAIN unless you've specified decimalDivisor as 1 in the options. You have been warned.

Unless otherwise noted, all methods will resolve the promise upon success and sample return data is supplied below. Any errors will reject the promise with an error condition.

Methods noted having options have parameters that may be optional or required as documented.

WebSocket Connections

A WebSocket socket.io server is initialized if enableWebSocket is true in the initialization of the module. The server is created on the bindPort specified + 1.

This server requires that the client authenticates otherwise you will not receive any of the below events aside from the challenge event. Authentication must occur within 10 seconds or the socket will be disconnected.

If the nonce column is Yes you may send a nonce in the payload in addition to the options defined.
