task

I'm new using celery and have a question. I have this simple task: @app.task(name='test_install_queue') def test_install_queue(): return subprocess.call("exit 0",shell=True) and I am calling this task later in a test case like result = tasks.test_default_queue.apply_async(queue="install") The task run successfully in the queue install (because I am seeing it in the celery log, and it completes fine. But I would like to know a programmatically way of finding in which queue was the task test_install_queue run, from the object stored in result . Thank you! EDIT: I've changed the tasks to be like:

I am trying to wrap my head around synchronously calling async functions and deadlock. In the below example I am blocking an async call which internally uses ConfigureAwait(false) which as far as I can tell should prevent deadlock. The first call to the web service does not deadlock. However, the second one that happens within a continuation that syncs back to the UI thread deadlocks. GetBlocking_Click is a click event in a WPF app so both the first and the second request happen on the UI thread. private void GetBlocking_Click(object sender, RoutedEventArgs e) { const string uri = "http://www

In Groovy, I overwrite a task like this: task jar(overwrite: true) { ... } How do I do that with Kotlin-dsl? I know that I can create a task like this: tasks { val jar by creating { ... } } but I can't find the equivalent way to declare it as overwrite, this leads to an error By opening an issue on the kotlin-dsl github I found the correct syntax: tasks.replace("jar") { ... } However, this is the old way and does not work within a tasks { } block, so this issue will be further tracked here 来源： https://stackoverflow.com/questions/48553029/how-do-i-overwrite-a-task-in-gradle-kotlin-dsl

In my MVC application, I sometimes get an exception like: System.Net.WebException: The request was aborted: The request was canceled. at System.Net.HttpWebRequest.BeginGetRequestStream(AsyncCallback callback, Object state) at System.Net.Http.HttpClientHandler.StartGettingRequestStream(RequestState state) at System.Net.Http.HttpClientHandler.<>c__DisplayClass4.<PrepareAndStartContentUpload>b__0(Task task) at System.Threading.Tasks.Task.Execute() --- End of inner exception stack trace --- EDIT Here's another kind I'm seeing: System.Exception: Unhandled Task Error ---> System

I am implementing an interface method that is asynchronous (returns Task). However, my implementation is by necessity synchronous. What's the best way to do this? Is there some built-in way to do this? Here are several options I'm considering: Option 1: Task.FromResult return Task.FromResult(ComputeResult()); This is good because my code runs synchronously. The disadvantage is that if ComputeResult() fails or is canceled my method throws instead of returning a failed task. Option 2: Task.Run return Task.Run(() => ComputeResult()); This propagates failure and cancellation more naturally.

Here is my minimal example producing the problem: using System.Runtime.InteropServices; using System.Threading.Tasks; using Excel = Microsoft.Office.Interop.Excel; class Program { static void Main(string[] args) { Task.Run(() => { Excel.Application app = new Excel.Application(); if (app != null) { app.Quit(); Marshal.FinalReleaseComObject(app); app = null; } }); } } This results in the following exception: The last part in Japanese says the "EventSetInformation" of DLL advapi32.dll entry point cannot be found . I'm having difficulty understanding what is going on. Basically why is this
