nos / nos-local

nOS Local

An environment for nOS development.

For now, manually start the neo-local environment and load contracts:

$ git clone https://github.com/nos/nos-local.git
$ cd nos-local
$ make run

If you exit the neo-python prompt, access it again with Docker:

$ sudo docker exec -it neo-python /bin/sh -c /bin/bash
$ np-prompt -p -v

Windows enviroment

Install Docker: https://docs.docker.com/docker-for-windows/install/#what-to-know-before-you-install Switch to linux containers (right click on tray icon)

$ git clone https://github.com/nos/nos-local.git
$ cd nos-local
$ makeWIN

Once you're at the neo-python prompt (wallet password is "coz"):

open wallet ./neo-privnet.wallet
build /smart-contracts/contract.py
import contract /smart-contracts/contract.avm 0710 05 True False False

Fill out the prompts for the contract meta data. Just hit [enter] if you're in a hurry 😉.

Wait a 🔥 minute and the nOS name service contract is deployed!

Let's register an example domain name with nOS:

testinvoke 9a309cfe03cead5b653bbb11f68ff6beced8f031 RegisterDomain ['AK2nJJpJr6o664CWJKi1QRXjqeic2zRp8y', 'bucket.neo', 'https://ihasabucket.com/', 'AK2nJJpJr6o664CWJKi1QRXjqeic2zRp8y']

Wait for the TX to clear, and test your domain is registered:

testinvoke 9a309cfe03cead5b653bbb11f68ff6beced8f031 GetDomain ['AK2nJJpJr6o664CWJKi1QRXjqeic2zRp8y', 'bucket.neo']

Visit nos://bucket.neo in the client!

nos-local's Issues

NeoSCAN and other clients cannot connect to neo local

Expected Behavior

NEOScan should get the number of transactions and addresses from neo local chain.

Current Behavior

NEOScan show empty fields regarding the number of transactions and addresses.

Steps to Reproduce

1. clone nos-local
2. make run
3. open localhost:4000

Possible Solution

Cannot start Neo Scan - MAC

I am trying to run the nos-local shell via "make run"
I observed that the neo scan container starts and then stops with an exception after few seconds. When I observed the logs of the container, I can see several instances of exception below -

Action required: Greenkeeper could not be activated 🚨

🚨 You need to enable Continuous Integration on all branches of this repository. 🚨

To enable Greenkeeper, you need to make sure that a commit status is reported on all branches. This is required by Greenkeeper because it uses your CI build statuses to figure out when to notify you about breaking changes.

Since we didn’t receive a CI status on the greenkeeper/initial branch, it’s possible that you don’t have CI set up yet. We recommend using Travis CI, but Greenkeeper will work with every other CI service as well.

If you have already set up a CI for this repository, you might need to check how it’s configured. Make sure it is set to run on all new branches. If you don’t want it to run on absolutely every branch, you can whitelist branches starting with greenkeeper/.

Once you have installed and configured CI on this repository correctly, you’ll need to re-trigger Greenkeeper’s initial pull request. To do this, please delete the greenkeeper/initial branch in this repository, and then remove and re-add this repository to the Greenkeeper App’s white list on Github. You'll find this list on your repo or organization’s settings page, under Installed GitHub Apps.

TestInvoke Doesn't Work on Sample Contract

I am trying the sample contract.py present in the codebase which is used to register and transfer domain. I used the create-nos-app boilerplate to create a react application and filled the details of contract for invocation as below:

   // Add your smart contract's scriptHash here
    const scriptHash = "e60a3fa8149a853eb4dff4f6ed93c931646a9e22";
    // The operation of your smart contract you want to (test)invoke
    const operation = "RegisterDomain";

    // The necessary arguments for you (test)invoke
    const args = ['AK2nJJpJr6o664CWJKi1QRXjqeic2zRp8y', 'google.nos', 
    'AK2nJJpJr6o664CWJKi1QRXjqeic2zRp8y', 'https://ihasabucket.com/'];

    // The storagekey you want to query
    const key = "google.nos.target";

Problems:

• The "RegisterDomain" operation doesn't work. The value is never stored to the blockchain.
• "Invoke" always returns error.

I am using local environment. "GetDomain" and "GetStorage" works if I set the domain from the nos-local shell.
I am not sure about how to test "RegisterDomain" and "Invoke"

Update neo-local

Currently the neo-local is linked to the NeoAuth version of Neo-Local. This version is old and outdated.

We should replace this submodule with the one from CoZ - which is maintained and compatible with windows aswell
