BackgroundProcess | longer maintained ] BackgroundProcess is a PHP | Reactive Programming library

In my web-application I have action with long-running task and I want to call this task in background. So, according to documentation .net core 3.1 Queued background tasks I use such code for this:

Recently I asked a question on StackOverflow about long running background Tasks in asp.net core. Since then I have tried everything from here https://docs.microsoft.com/cs-cz/aspnet/core/fundamentals/host/hosted-services?view=aspnetcore-5.0&tabs=visual-studio and if i do what I do it will just stop at some time. And it will stop even if I wrap it in IServiceProvider.CreateScope and await it. The only thing I still didn't try and I'm trying to avoid it, is creating dedicated .net application that would just read queue and do what it's supposed to do. And also I thing that it's overkill to create queue for it, I just want to run it in background asynchronously but it just stops. Sorry if it's some stupid bug but this is my first asp.net project and I'm fixing this problem for week now.

hello i have been using the custom_splash package and as the docs says if i want to Execute a function in background and based on the value from that function navigate to different screen i have to do the following :

I have a spring mvc application where I am trying to add spring boot actuator for performance metrics. I am getting an exception when running it into tomcat server. Can anyone please help me how can I use spring boot actuator 2.4.2 into spring 5.2.8 for getting the performance metrics? Spring version : 5.2.8.RELEASE Spring Boot actuator version : 2.4.2

Using ASP.NET Core .NET 5. Running on Windows.

Users upload large workbooks that need to be converted to a different format. Each conversion process is CPU intensive and takes around a minute to complete.

The idea is to use a pattern where the requests are queued in a background queue and then processed by background tasks.

So, I followed this Microsoft article

The queuing part worked well but the issue was that workbooks were executing sequentially in the background:

I am attempting to use the BackgroundService and IBackgroundTaskQueue to have a service monitoring a queue to do work. I've started with the sample in the MS docs here: https://docs.microsoft.com/en-us/aspnet/core/fundamentals/host/hosted-services?view=aspnetcore-5.0&tabs=visual-studio#queued-background-tasks

My problem is it doesn't appear like my QueueHostedService is ever started. None of my breakpoints get hit for it. For now I was using the same "MonitorLoop" concept to queue work, that is starting and working fine to queue records, but they never get Dequeued and nothing in the QueueHostedService gets hit (Constructor, ExecuteAsync, BackgroundProcessing).

My sample code is the exact same as the documentation as far as I can tell with the following modifications: The monitor loop is async, but it is starting up fine so I don't think that is the problem. QueueHostedService and BackgroundTaskQueue are exactly the same as their samples. The adding of the services looks pretty much the same to me:

I'm writing an extension for Firefox to allow me to scrape some data from a web site.

A simplified description is that the site contains an index page with a list of links to subsidiary pages that contain the data I want. I browse to the index page where the extension detects the URL and asks if I want to scrape it. If I say yes, the content script scrapes the list of subsidiary page URLs and passes them to the background process which should open each page in turn in a new tab, scrape the data, then close the tab. To avoid issues at the server I set up a series of timeouts to create the new tabs, currently at 10 second intervals.

Once all the data is scraped it need to be passed to a PHP script on a server, but that's beyond the scope of this question.

All this works as described, except that I see this message appear on the console for each tab opened and closed (the tab number varies):

15:06:27.426 Uncaught (in promise) Error: Invalid tab ID: 171

I've puzzled over this most of the day but I can't track down the source of this error. It's doubly confusing because the code does exactly what I want.

Question: where is this error coming from, and what do I need to do to fix it?

Here's the code:

I am trying to get informataion from battery. So i've created BroadcastReceiver, to read this values in background. I've got the problem with get isCharging state from battery. I've got always false. I am trying to use this code:
