QUESTION

Is my M1 chip rejecting my Nix Build commands?

Asked 2021-Nov-04 at 04:34

I was trying to run a Nix command to build a project:

nix build -f default.nix plutus.haskell.packages.plutus-core.components.library

and I received this error!

error: attribute 'aarch64-darwin' missing, at /nix/store/cyfj6bd0n0ckvkm67mhjyg1qcvrfgsg9-source/artifact.nix:11:10

Is 'aarch64-darwin' referring to 64 bit architecture?

ANSWER

Answered 2021-Aug-20 at 00:00

Your M1 chips is not rejecting your builds, but some Nix expression is not prepared for M1 yet.

plutus was written by IOHK iirc, so you can check with them what's the status of M1 support for their software. If they don't already have a GitHub issue or other communication about it, it may be helpful to tell them the output of, say, ls /nix/store/cyfj6bd0n0ckvkm67mhjyg1qcvrfgsg9-source as context for the error message when you report the issue. I'm sure they'd like to improve the error if you mention it; they have to edit that code anyway.

QUESTION

How to set HTTP version with Haskell request

Asked 2021-Sep-09 at 08:57

I'm working through the first iteration of the Plutus Pioneer Lectures, and the code for lecture 6 that gets the exchange rate from coinmarketcap.com returns a 403 error:

getExchangeRate = runReq defaultHttpConfig $ do
    v <- req
        GET
        (https "coinmarketcap.com" /: "currencies" /: "cardano")
        NoReqBody
        bsResponse
        mempty
    let priceRegex      = "priceValue___11gHJ\">\\$([\\.0-9]*)" :: ByteString
        (_, _, _, [bs]) = responseBody v =~ priceRegex :: (ByteString, ByteString, ByteString, [ByteString])
        d               = read $ unpack bs :: Double
        x               = round $ 1_000_000 * d
    liftIO $ putStrLn $ "queried exchange rate: " ++ show d
    return x

if I try the same url in curl with the -L option to follow redirects, it works:

curl -i -L 'https://coinmarketcap.com/currencies/cardano'

The only difference I can see is that the Haskell code's request is HTTP/1.1, but the curl request is being sent with HTTP/2

I'd like to change the version of HTTP that the Haskell library is sending, in order to check if this is the problem. However, I'm a relative newbie to Haskell, so I haven't been able to figure out if there's a way with the Haskell Network.HTTP.Req module to set the HTTP version.

Is there a way to do this?

TIA

Answered 2021-Sep-09 at 08:57

I believe coinmarketcap.com is blocking requests that don't have a User-Agent header specified. You can do that like this:

getExchangeRate = runReq defaultHttpConfig $ do
    v <- req
        GET
        (https "coinmarketcap.com" /: "currencies" /: "cardano")
        NoReqBody
        bsResponse
        (header "User-Agent" "my-app/0.1.0.0")
    let priceRegex      = "priceValue___11gHJ\">\\$([\\.0-9]*)" :: ByteString
        (_, _, _, [bs]) = responseBody v =~ priceRegex :: (ByteString, ByteString, ByteString, [ByteString])
        d               = read $ unpack bs :: Double
        x               = round $ 1_000_000 * d
    liftIO $ putStrLn $ "queried exchange rate: " ++ show d
    return x

With this code the request finishes correctly but I run into a pattern match error. It seems the priceValue___11gHJ regex doesn't work anymore.

Plutus Interpreter Error in Plutus Playground

Asked 2021-Mar-06 at 08:40

This code compiles but when I click on Evaluate I get this error. I'm not sure if this is from the playground or not because I used the same code from their new tutorial .

The error doesn't show up when I compile it only happens when I attempt view transactions by clicking Evaluate. I'm not sure if this is an issue with the code because it passed compile.

The Error message doesn't seem about the code itself. Heck it even errors out with zero transactions on the test block chain. I tried with with different variations on transactions. I know these updates just came out this week. I double checked the documentation. And I'm not seeing what its talking about.

You are missing the endpoints declaration. You must define endpoints for any Plutus Playground contract for the UI with the type of:

endpoints :: Contract SplitSchema T.Text ()

For the Split App in question:

endpoints = (lock >>= lockFunds . mkSplitData) `select` (unlock >>= unlockFunds . mkSplitData)

...

endpoints = (lock >>= lockFunds . mkSplitData) `select` (unlock >>= unlockFunds . mkSplitData)

QUESTION

Flask Docker container SocketIO Issues

Asked 2020-Dec-27 at 01:33

I have a Flask application that uses SocketIO to fetch data from Postgres live.

The app works fine when I run this locally.

The problem arouses when I use docker-compose to host my Flask app. My JS client and flask server is hosted into a single app and on the same container.

My socketio in JS is like this:

var socket = io().connect(window.location.protocol + '//' + document.domain + ':' + location.port);

Dockerfile:

# Using python 3.7 in Alpine
FROM python:3.6.5-stretch

# Set the working directory to /app
WORKDIR /app

# Copy the current directory contents into the container at /app
ADD . /app

RUN apt-get update -y && apt-get upgrade -y

# Install the dependencies from requirements
RUN pip install -r requirements.txt

# Tell the port number the container should expose
EXPOSE 8083

# Run the command
ENTRYPOINT ["./entry.sh"]

entry.sh:

#!/bin/sh
gunicorn -k geventwebsocket.gunicorn.workers.GeventWebSocketWorker -b :8083 -w 5 run:app

My docker-compose is as such:

version: "3.8"

services:
  fortweet:
    container_name: fortweet
    build: ./
    env_file:
      - secret.env
    networks:
      - plutusnet
    ports:
      - 8083:8083
    restart: always

networks:
  plutusnet:
    name: plutus_network
    driver: bridge

I've also tried to use var socket = io.connect('http://public_ip_of_website:8083') but my socket connection still doesn't work.

How it should normally work is when i run this locally and click a certain button, it executes this function in my JS:

$("#tweets-live-start").click(function(){
    if (is_streaming == true){
      alert("A stream is already running")
    }else{
      $.ajax({
        type: "POST",
        url : "/admin/startstream",
        data: {url : "print \"hello\""},
        contentType: 'application/json;charset=UTF-8'
      });
    }
  });

When my server gets the hello, it starts a tweet streaming and emits them through the socket. Then my socket captures them as such:

// Listens for tweets
socket.on('stream-results', function(results){

  // Insert tweets in divs
  $('#live-tweet-container').prepend(`
  <div class="row justify-content-md-center mt-3">
    <div class="col-md-2">
        <img width="56px" height="56px"  src="${results.profile_pic !== "" ? results.profile_pic : "/static/icons/profile-pic.png"}" class="mx-auto d-block rounded"  alt="">
    </div>
    <div class="col-md-8 my-auto">
      <div><b>${results.author}</b></div>
      <div>${results.message}</div>
    </div>
  </div>
  `);
});

But when i run it on docker, nothing happens.

When i check my browser JS console, it seems that it is polling with a bad request and i don't know why:

index.js:83 GET http://th3pl4gu3.com:8083/socket.io/?EIO=3&transport=polling&t=NPYYrxr 400 (BAD REQUEST)

Here is my docker ps for more info:

I don't think this is an accessibility issue because i tried several telnet tests from each container and to each container also.

I checked logs of the docker container and it gives this:

FYI, the plutus container is just my Postgres database that my web app connects to.

Can anyone please help me ?

The 400 (BAD REQUEST) indicates that there is a communication between Your Browser+JS and the Flask app.

I suspect an issue between The Flask App and Postgres.

Your Postgres has to be in the same network as you application server (the service you call "fortweet" in your docker-compose. Plus, you have give it a hostname so the app server can resolve it internally.

version: "3.8"

services:
  postgres:                               #    <=== same name here 
    image: postgres/postgres:11
    networks:
      - plutusnet                      #  <== same network

  fortweet:
    container_name: fortweet
    build: ./
    env_file:
      - secret.env
    networks:
      - plutusnet                        #  <=== same network
    links:
      - db:postgres                      #    <== than here
    ports:
      - 8083:8083
    restart: always

networks:
  plutusnet:
    name: plutus_network
    driver: bridge`

Then the app must be configured to use "postgres:5432" to connect to DB.

Have a try and tell us.

QUESTION

the recylerView does not shown in the app

Asked 2020-Feb-29 at 17:05

Hey I'm new to working with Android and took this app to make I am following a tutorial, and the tutorial reads and writes data from MainActivity.java while I am trying to work in a Fragment.

Although there is no error the app shows nothing the Firebase Realtime Database has JSON data which isn't being displayed in RecylerView as expected.

Here are my Files

I can't understand where is the actual problem.

Edit: Included JSON Files.

{
    "Plutus":{
        "Task1":{
            "tasktitle":"Create an awesome app"
        },

        "Task2":{
            "tasktitle":"Learn More Android"
        },

        "Task3":{
            "tasktitle":"Learn Android Pentesting too"
        },

        "Task4":{
            "tasktitle":"Oi don't forget Bug Hunting"
        }
    }

A few problems in your code:

You're not handling the Plutus level of your JSON in your code.
You're acting as if there can be multiple nodes in the snapshot, but you're actually loading a very specific node. So you don't need to loop over getChildren().
Since you're loading the title node only, the result is not a MyTasks.

To load only the title of the one task, you'd do something like:

DatabaseReference taskDatabaseReference = FirebaseDatabase.getInstance().getReference();
DatabaseReference taskuser = taskDatabaseReference.child("Plutus/Task1/tasktitle");

taskuser.addValueEventListener(new ValueEventListener() {
    @Override
    public void onDataChange(@NonNull DataSnapshot dataSnapshot) {
        Log.i("Firebase", dataSnapshot.getValue(String.class));
    }

    @Override
    public void onCancelled(@NonNull DatabaseError databaseError) {
        throw databaseError.toException(); // make sure to show the programming error
    }
});

To load a single task, but the entire task, it'd be something like:

DatabaseReference taskDatabaseReference = FirebaseDatabase.getInstance().getReference();
DatabaseReference taskuser = taskDatabaseReference.child("Plutus/Task1");

taskuser.addValueEventListener(new ValueEventListener() {
    @Override
    public void onDataChange(@NonNull DataSnapshot dataSnapshot) {
        MyTasks p = dataSnapshot.getValue(MyTasks.class);
        Log.i("Firebase", p.toString());
    }

    @Override
    public void onCancelled(@NonNull DatabaseError databaseError) {
        throw databaseError.toException(); // make sure to show the programming error
    }
});

And to load all tasks, and add them to an adapter/view, it'd be something like:

taskAdapter = new TaskAdapter(this, list);
ourTasks.setAdapter(taskAdapter);

DatabaseReference taskDatabaseReference = FirebaseDatabase.getInstance().getReference();
DatabaseReference taskuser = taskDatabaseReference.child("Plutus");

taskuser.addValueEventListener(new ValueEventListener() {
    @Override
    public void onDataChange(@NonNull DataSnapshot dataSnapshot) {
        for (DataSnapshot taskSnapshot: dataSnapshot.getChildren()){
            MyTasks p = taskSnapshot.getValue(MyTasks.class);
            list.add(p);
        }
        taskAdapter.notifyDataSetChanged();
    }

    @Override
    public void onCancelled(@NonNull DatabaseError databaseError) {
        throw databaseError.toException(); // make sure to show the programming error
    }
});

You'll note that I pulled the adapter out of the listener here. You don't need to rebuild a new adapter every time the data changes, but can instead just update the data in list and then notify the adapter, so that it updates the UI.

Install Plutus

You can download it from GitHub.
You can use Plutus like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
