redis is a C library typically used in Database applications. redis has no bugs, it has a Permissive License and it has medium support. However redis has 1 vulnerabilities. You can download it from GitHub.

Redis is often referred to as a data structures server. What this means is that Redis provides access to mutable data structures via a set of commands, which are sent using a server-client model with TCP sockets and a simple protocol. So different processes can query and modify the same data structures in a shared way.

redis Key Features

Redis cares to store them on disk, even if they are always served and modified into the server memory. This means that Redis is fast, but that it is also non-volatile.

The implementation of data structures emphasizes memory efficiency, so data structures inside Redis will likely use less memory compared to the same data structure modelled using a high-level programming language.

Redis offers a number of features that are natural to find in a database, like replication, tunable levels of durability, clustering, and high availability.

QUESTION

How to invalidate a view cache using django-cacheops

Asked 2022-Mar-19 at 15:05

I have a view and I cached it in views.py using django-cacheops (https://github.com/Suor/django-cacheops):

@cached_view(timeout=60*15)
@csrf_exempt
def order(request, usr):
    ...

The regex for order view in urls.py:

url(r'^order/(?P<usr>\D+)$', views.order, name='ord')
# Example Url: http://127.0.0.1:8000/order/demo (demo is the user name)

And I want to invalidate the cached view order inside the below view:

@login_required 
def available(request, pk, avail):
    pk = int(pk)
    avail = strtobool(avail)
    if avail:
        Product.objects.filter(id = pk).update(available = True)
    else:
        Product.objects.filter(id = pk).update(available = False)
    return HttpResponseRedirect(reverse_lazy('yc'))

According to the docs, we can achieve this by doing:

@login_required 
def available(request, pk, avail):
    pk = int(pk)
    avail = strtobool(avail)
    if avail:
        Product.objects.filter(id = pk).update(available = True)
        order.invalidate("http://127.0.0.1:8000/order/demo", "demo")
        #it's a dummy url I've handled it dynamically in my code
    else:
        Product.objects.filter(id = pk).update(available = False)
        order.invalidate("http://127.0.0.1:8000/order/demo", "demo")
        #it's a dummy url I've handled it dynamically in my code
    return HttpResponseRedirect(reverse_lazy('yc'))

But it's not working. Here are my logs using redis-cli monitor:

It looks like it's deleting some other cache.

I've also raised the issue in the repo of django-cache, you can check it for more information: https://github.com/Suor/django-cacheops/issues/425

ANSWER

Answered 2022-Mar-19 at 14:37

Since you used a named group usr in your regex, Django passes it as a keyword argument:

url(r'^order/(?P<usr>\D+)$', views.order, name='ord')

But you are trying to invalidate the cache with a positional argument:

order.invalidate("http://127.0.0.1:8000/order/demo", "demo")

Instead, invalidate it with the corresponding keyword argument:

order.invalidate("http://127.0.0.1:8000/order/demo", usr="demo")

Redis NodeJs server error,client is closed

Asked 2022-Feb-11 at 05:16

I am developing an application where chats has to cached and monitored, currently it is an local application where i have installed redis and redis-cli. The problem i'm facing is (node:5368) UnhandledPromiseRejectionWarning: Error: The client is closed Attaching code snippet below

//redis setup
const redis = require('redis');
const client = redis.createClient()//kept blank so that default options are available
  

//runs when client connects
io.on("connect", function (socket) {

  //this is client side socket
  //console.log("a new user connected...");

  socket.on("join", function ({ name, room }, callback) {
    //console.log(name, room);
    const { msg, user } = addUser({ id: socket.id, name, room });
   // console.log(user);
    if (msg) return callback(msg); //accessible in frontend

    //emit to all users
    socket.emit("message", {
      user: "Admin",
      text: `Welcome to the room ${user.name}`,
    });
    //emit to all users except current one
  
    socket.broadcast
      .to(user.room)
      .emit("message", { user: "Admin", text: `${user.name} has joined` });

    socket.join(user.room); //pass the room that user wants to join

    //get all users in the room
    io.to(user.room).emit("roomData", {
      room: user.room,
      users: getUsersInRoom(user.room),
    });

    callback();
  }); //end of join

  //user generated messages
  socket.on("sendMessage",  async(message, callback)=>{
    const user = getUser(socket.id);

    //this is where we can store the messages in redis
    await client.set("messages",message);

    io.to(user.room).emit("message", { user: user.name, text: message });
    console.log(client.get('messages'));
    callback();
  }); //end of sendMessage

  //when user disconnects
  socket.on("disconnect", function () {
    const user = removeUser(socket.id);
    if (user) {
     
      console.log(client)

      io.to(user.room).emit("message", {
        user: "Admin",
        text: `${user.name} has left `,
      });
    }
  }); //end of disconnect

I am getting above error when user sends a message to the room or when socket.on("sendMessage") is called.

Where am I going wrong?

Thank you in advance.

You should await client.connect() before using the client

Hi i was deploying a branch on heroku and threw up this error. I also tried deploying a branch which worked perfectly, but that is also showing the same error.

QUESTION

Why the swagger doesn't open in .NET 6?

Asked 2021-Dec-15 at 15:11

Well, I was doing a DDD project, specifically using redis, but I don't think that has anything to do with it.

The problem is, the swagger doesn't appear to me, it fails, but when I make requests in postman it works normally.

Thats the error:

 Microsoft.AspNetCore.Diagnostics.DeveloperExceptionPageMiddleware[1]
  An unhandled exception has occurred while executing the request.
  System.TypeLoadException: Could not load type 'Microsoft.AspNetCore.Http.Metadata.ITagsMetadata' from assembly 'Microsoft.AspNetCore.Http.Abstractions, Version=6.0.0.0, Culture=neutral, PublicKeyToken=adb9793829ddae60'.

Startup file (ConfigureServices):

public void ConfigureServices(IServiceCollection services)
{
        services.AddRedisContext(Configuration);
        services.AddControllers();
        services.AddSwaggerGen(c =>
        {
            c.SwaggerDoc("v1", new OpenApiInfo { Title = "Basket.Api", Version = "v1" 
        });
});

My method in extension method class:

public static IServiceCollection AddRedisContext(this IServiceCollection services, IConfiguration config)
{
        services.AddStackExchangeRedisCache(options =>
        {                
            options.Configuration = config["CacheSettings:ConnectionString"];
        });

        services.AddScoped<IBasketRepository, BasketRepository>();
        services.AddScoped<IBasketService, BasketService>();

        return services;
 }

The Package reference:

<Project Sdk="Microsoft.NET.Sdk.Web">

  <PropertyGroup>
    <TargetFramework>net6.0</TargetFramework>
  </PropertyGroup>

  <ItemGroup>    
    <PackageReference Include="Swashbuckle.AspNetCore" Version="6.2.3" />
  </ItemGroup>

  <ItemGroup>
    <ProjectReference Include="..\Basket.Infra.Data\Basket.Infra.Data.csproj" />
  </ItemGroup>

</Project>

I also commented the lines referring to redis and it still gave the same error. So it's almost certainly something involving the swagger.

ANSWER

Answered 2021-Dec-15 at 15:11

In my case, it was the SDK not running the proper net6.0 version.

While the whole project was using new net6.0 NuGet packages, the local SDK on that one machine I was working on was still net5.0. After installing .net6.0, Swashbuckle 6.2.3 was working again, and all was as expected.

Docker image does not run with specified Python version

Asked 2021-Oct-08 at 00:53

I have a Dockerfile

RUN pip install redis
RUN pip3 install glob2

RUN pip install face_recognition
COPY ./worker.py /worker.py

CMD  python3 worker.py

I build the image and run my image with docker run -it {image_id}, but I see errors from python app - It complains about f-strings syntax as it is supported since python 3.6 I address that it uses some older python.

I debugged and get python version it printed 1.19.0

While creating a docker multi stage build, your final container will always be based off the last docker container you have referenced

So in your case it will be aaftio/face_recognition which uses Python 3.4.9 and not python:3.7.12-slim-buster which uses Python 3.7.12

Reference for docker multi stage build - here

You can try something like this

FROM aaftio/face_recognition as intermediate
RUN pip install face_recognition


FROM python:3.7.12-slim-buster

#Copy the python installed libraries from intermediate container
#COPY --from=intermediate face_recognition

RUN pip install redis
RUN pip3 install glob2
COPY ./worker.py /worker.py
COPY ./rediswq.py /rediswq.py

CMD  python3 worker.py

QUESTION

Bitnami Redis on Kubernetes Authentication Failure with Existing Secret

Asked 2021-Sep-02 at 12:07

I'm trying to install Redis on Kubernetes environment with Bitnami Redis HELM Chart. I want to use a defined password rather than randomly generated one. But i'm getting error below when i want to connect to redis master or replicas with redis-cli.

I have no name!@redis-client:/$ redis-cli -h redis-master -a $REDIS_PASSWORD 
Warning: Using a password with '-a' or '-u' option on the command line interface may not be safe.
Warning: AUTH failed

I created a Kubernetes secret like this.

---
apiVersion: v1
kind: Secret
metadata:
  name: redis-secret
  namespace: redis
type: Opaque
data:
  redis-password: YWRtaW4xMjM0Cg==

And in values.yaml file i updated auth spec like below.

auth:
  enabled: true
  sentinel: false
  existingSecret: "redis-secret"
  existingSecretPasswordKey: "redis-password"
  usePasswordFiles: false

If i don't define existingSecret field and use randomly generated password then i can connect without an issue. I also tried AUTH admin1234 after Warning: AUTH failed error but it didn't work either.

You can achieve it in much simpler way i.e. by running:

$ helm install my-release \
  --set auth.password="admin1234" \
    bitnami/redis

This will update your "my-release-redis" secret, so when you run:

$ kubectl get secrets my-release-redis -o yaml

you'll see it contains your password, already base64-encoded:

apiVersion: v1
data:
  redis-password: YWRtaW4xMjM0Cg==
kind: Secret
...

In order to get your password, you need to run:

export REDIS_PASSWORD=$(kubectl get secret --namespace default my-release-redis -o jsonpath="{.data.redis-password}" | base64 --decode)

This will set and export REDIS_PASSWORD environment variable containing your redis password.

And then you may run your redis-client pod:

kubectl run --namespace default redis-client --restart='Never'  --env REDIS_PASSWORD=$REDIS_PASSWORD  --image docker.io/bitnami/redis:6.2.4-debian-10-r13 --command -- sleep infinity

which will set REDIS_PASSWORD environment variable within your redis-client pod by assigning to it the value of REDIS_PASSWORD set locally in the previous step.

If you are reading this README you are likely in front of a Github page or you just untarred the Redis distribution tar ball. In both the cases you are basically one step away from the source code, so here we explain the Redis source code layout, what is in each file as a general idea, the most important functions and structures inside the Redis server and so forth. We keep all the discussion at a high level without digging into the details since this document would be huge otherwise and our code base changes continuously, but a general idea should be a good starting point to understand more. Moreover most of the code is heavily commented and easy to follow. Source code layout ---. The Redis root directory just contains this README, the Makefile which calls the real Makefile inside the src directory and an example configuration for Redis and Sentinel. You can find a few shell scripts that are used in order to execute the Redis, Redis Cluster and Redis Sentinel unit tests, which are implemented inside the tests directory.
