Jenkins pipeline does not create postgresql_data volume but running docker compose up -d commad manually creates volumes
I'm pretty new to whole docker,docker-compose,jenkins and whole CI-CD concept. So, I may be missing a very simple point. My application is a django web app with postgresql and nginx. If I run docker compose build and docker compose up -d, 3 containers runs and docker volumes are created without any problems. Now I am trying to run these 3 containers with jenkins. I clone my app's repo to jenkins and run docker compose build and docker compose up -d in my pipeline. My app works, static volume is created but postgresql_data docker volume is not created and it's gone if I restart my host machine I thought this might be because of user permissions but the static volume is created by the same jenkins task. Thanks in advance. jenkinsfile pipeline { agent { node { label 'agent-compose' } } environment{ DOCKERHUB_CREDENTIALS = credentials('DockerHub') } stages { stage('Build') { steps { sh 'docker compose build' echo 'Docker compose build is Completed, these images are created:' } } stage('Run The Services') { steps { sh 'docker compose up -d' } } stage('Login To Docker Hub') { steps { sh 'echo $DOCKERHUB_CREDENTIALS_PSW | docker login -u $DOCKERHUB_CREDENTIALS_USR --password-stdin' echo 'Login completed' } … -
How to Access method decorated with @action decorator of a view inherited from APIView Class in urls.py file in DRF?
I need to apply different permission on different methods of my View class which is inherited from APIView in a DRF application. To achieve this I am using @action decorator on my methods of view. Here is views.py code class UserView(APIView): @action(methods=['post'], detail=False, permission_classes=[AllowAny]) def create(self, request): serializer = UserRegSerializer(data=request.data) user_service = UserService() try: serializer.is_valid(raise_exception=True) serialized_data = serializer.validated_data registered_user = user_service.create_user(serialized_data) payload = registered_user.__dict__ response = ResponseGenerator(payload, constants.SUCCESS_KEY) except Exception as e: response = ResponseGenerator(e) return Response(data={"Response": response.get_custom_response()}) I am not getting that how could I access this method in my urls.py file against the pattern '/user', here is my urls.py code. urlpatterns = [ path('user', UserView.as_view()), ] I was using ChatGPT to answer this query of mine. It suggested some ways to use a dictionary object passed {'post':'create'} in as_view() method of View in urls.py as following. urlpatterns = [ path('user', UserView.as_view({'post':'create'})), ] In this it told me that key of the dictionary should be the http method used to access that method against the url pattern and value of dictionary should be the method which you want to access against the given url. But its not working, and gives me following error when I try to start my … -

Considerations of building an Android service as system app (OEM)
I'm working on an OEM project where we need a background service (no UI) to be working continuously. Of course it'll be an app signed with the OEM key, so it shouldn't be any trouble related to background services Android's restrictions. But, as it is the first time developing this, is there any consideration regarding the implementation of the service lifecycle and workflow? Plus, anything important to consider regarding the testing flow of the project? Thank you, any help related to OEM-apps development will be much appreciated. -
how to access all buttons in every container
I want to assign an event listener for every button in every container, but I don't want to loop through the buttons first, because Firstly I want to access the container to use hidden inputs to be passed as parameter to every event listener. for(var i = 0 ; i<products.length;i++) { var id= products[i].getElementsByClassName('pr_id')[0].value; var price = products[i].getElementsByClassName('pr_price')[0].value; var Pname = products[i].getElementsByClassName('pr_name')[0].value var btn = products[i].getElementsByTagName('button')[0]; btn.addEventListener('click',function() { openpopUp(id,price,Pname) }) } but this way the parameters of every button function will be over written. In the end they all have the same parameter ( parameter of last item in the list). HTML code: <div> <div class="productCard"> <img src="'.$row['Picture'].'"> <h3><a href="productDetails.php?id='.$row['Product_ID'].'">'.$row['Name'].'</a></h3> <h4>'.$row['price'].'</h4> <Button type="button" class="open">aa</Button> <input type="hidden" class="pr_id" id="producId" value="'.$row['Product_ID'].'"> <input type="hidden" class="pr_name" name="productName" value="'.$row['Name'].'"> <input type="hidden" class="pr_price" name="productPrice" value="'.$row['price'].'"> </div> </div> -
How to copy a custom .scss file's .css output to wwwroot in a Blazor app?
I have a Blazor WASM application that I'd like to have separate .scss files used for global styling that are not component specific CSS isolation files. Those are bundled and available at runtime, so no issue there. I'm looking for getting the transpiled .css file from it's corresponding .scss source file, and have that .css file copied to wwwroot so I can link to it in index.html. To hedge this a bit, I understand there already exists in wwwroot an app.css file where additional global styles can be applied. The problem with this is it's a .css file and I'd like the power of SASS so this isn't the option I'd like to use. You also can't put a .scss file inside wwwroot as it's not proper because files that need transpiled need to be outside that folder and in the project itself; wwwroot is a target for static files to be hosted, not raw .scss source files. I'm leveraging LibSassBuilder to transpile my .scss files to .css so that's all taken care of. In this example I have a custom.css that's been transpiled from custom.scss and ready for use, but I need it copied to wwwroot. It's been a … -

How can you set the parallelism for a specific ingress for an embedded statefun application
I have a custom ingress which for various reasons should be run as a singleton. While I understand how the default parallelism can be set I do not see a way of controlling this for a specific operator or ingress when imbedded. I have searched the documentation but have yet to find anything related to this. -

Count of specific value and count of individual value
I have a table like: Id type status 1 coach 1.0 2 coach True 3 client Null 4 coach False 5 client Null 6 coach False 7 client Null 8 coach True 9 coach 1.0 10 client Null I want to create a column where coach status is active when value is 1.0 and True else status should be inaactive. Also want to add count of active and inactive values in another column and and total coach count as another column I tried this code Select id,(case when status in (1.0,True) then 'Active' else 'Inactive' end) as Status from table Where type ='Coach' But unable to add count of active and inactive and total coach -
MySQL tune slow delete
I'm using MySQL InnoDB, one of the most important tables has over 700 million records with totally 23 actively used indexes. I am trying to delete the records in a batch of 2000 based on the record date (and order by on primary key column). Each date has around 6 million records, I delete it date by date. Each batch takes around 25 seconds to complete. Since it is a Production database, I want this delete operation to complete faster. Is there a better way to do this? -
Pytorch Results Differ in Training eval() vs Testing/inference eval()
I am trying to replicate the results I get on my evaluation dataset in training with the same dataset in testing. For context, I am trying to denoise images and they are being passed a simple NN consisting of a few conv, relu and BN layers. My problem is that my results are quite close but there is always some disparity. For instance in training the model gets 37.49 dB and in testing it gets 37.40. I have done a bit of reading and it seems that this has to do with batchnorm in the model but setting track_running_stats to false hasnt helped as some people suggest. I also make sure to call model.eval() on my model and I use with torch.no_grad(): The only method I have found to bring the PSNR close is to test using a small minibatch (3 images) but this is not practical as the end goal is to process images seperately. I think this increase might also be due to the PSNR function itself processing larger batches at a time. -
Can GNU Octave handle dynamical plots for the GUI?
I tested this logging software for Arduino and it works great, for a while. The problem with this logging software is that the plot make the application freeze and I don't know why. I have been testing the software for a while and it seems that the plot is the cause of the problem. It freeze and then the whole application freeze. It does not matter even if I plot with regular plot, or if I call an object of the plot and update its X, Y vectors. https://github.com/DanielMartensson/GNU-Octave-Logger/blob/1c6001c115f402a6c3ec71c2ac95817666ea615b/export/wnd/GNU_Octave_Logger_thread.m#L98 % Focus on plot axis(wnd.plot); h = plot(rand(2)); [ code ] set(h, {'YData'}, {analogInPlot; analogOutPlot}); set(h, {'XData'}, {L; L}); legend(h, 'Analog in', 'Analog out'); So my question is: Even if I update the vectors, the plot can still freeze and then the whole application freeze as well. This is a combination with the GUI running. Can it be that GNU Octave cannot handle dynamical plots for GUI? If I remove the plot, then the application works fine. So it must be that GNU Octave cannot handle dynamical plots for the GUI? %set(h, {'YData'}, {analogInPlot; analogOutPlot}); %set(h, {'XData'}, {L; L}); %legend(h, 'Analog in', 'Analog out'); -
Javascript: How to reduce json when consecutive key is the same?
I have a json where I need to reduce the items when they are of a type (isSender). I need to reduce them when they are occuring consecutively. The data can change. The data looks like this: "messages": [ { "content": ["Foo"], "isSender": true }, { "content": ["Bar"], "isSender": true }, { "content": ["Lorem"], "isSender": true }, { "content": ["Ipsum"], "isSender": true }, { "content": ["Dolor"], "isSender": false }, { "content": ["Sit Amet"], "isSender": false }, { "content": ["No"], "isSender": true } ] I need the content to be an array of messages when the consecutive "isSender" key is the same. The output should look like this: "messages": [ { "content": ["Foo", "Bar", "Lorem", "Ipsum"], "isSender": true }, { "content": ["Dolor", "Sit amet"], "isSender": false }, { "content": ["No"], "isSender": true } ] So far I have tried looping through the message array and checking if next messages have the same "isSender" key. However this does not work for more than 2 messages. let deleteIndex = []; for(let i = 0 ; i < messages.length - 1; i++) { const currMs = messages[i]; const nextMs = messages[i + 1]; if (nextMs.isSender == currMs.isSender) { currMs.content.push(nextMs) deleteIndex.push(i + 1) // saving … -
Chromium video decoding issue
I work on a team that is developing a browser based video application. We have been experiencing an occasional severe degradation in the quality of our video starting around November 2022. It happens during a call and continues until the call is ended (the connection is ended), and appears to be a decoding issue (the screen looks pixelated/discolored but you retain some idea of the 'shape' of objects on the video feed). We use Pexip which acts as an MCU between participants, and have validated from Pexip's outbound packets that it is sending a clear video stream, however on the browser we see the issue nonetheless. This is only seen on a single participants video stream. The issue has only been seen on Chrome and Edge which default to VP8, and has not been reproduced on Firefox (defaults to H.264). This leads me to believe it is an issue with Chromium. I have struggled to find any logs that relate to the start of the issue, and am asking if you have any suggestions on where to look on Chrome's logs to find any indication that an issue has started or to understand more about why the issue is happening? … -
