问题 I have a JIRA filter which returns all the fixes in a future release: project = MyProject AND fixVersion = "1.1.1" and issuetype in standardIssueTypes() and status != Closed All of these issues have Sub-Tasks which I want to have in a new filter result. They do not have the fixVersion set. I have tried the parent filter but this only accepts Key or ID. Is there any way I can write a filter to access these without manually using something like parent in (MyProject-1,MyProject-2,MyProject-3

问题 The following code works based on the OpenMP 4.0 specification: The out and inout dependence-types. The generated task will be a dependent task of all previously generated sibling tasks that reference at least one of the list items in an in, out, or inout dependence-type list. This means that task3 becomes dependent of task2. Right? but it does not make sense! Why should an input-output dependency task be a dependent of an input dependency task? What do I need to do in order to make them

问题 I have the following line of code used to read asynchronously from a NetworkStream: int bytesRead = await Task<int>.Factory.FromAsync(this.stream.BeginRead, this.stream.EndRead, buffer, 0, buffer.Length, null); I'd like to make it support cancellation. I see that I can cancel tasks using a CancellationTokenSource, however I don't see any way I can pass it to TaskFactory.FromAsync(). Is it possible to make a FromAsync()-constructed task support cancellation? Edit: I want to cancel a task that

问题 I need to copy a war file via scp. I have added the jsch-0.1.42.jar to $ANT_HOME/lib but I'm still getting this error: Cause: the class org.apache.tools.ant.taskdefs.optional.ssh.Scp was not found. This looks like one of Ant's optional components. This is the result of running ant -diagnostics just in case: http://gist.github.com/320859 回答1: This looks like your problem, from the top of the diagnostics: optional tasks : not available Your $ANT_HOME/lib directory is missing ant-jsch.jar, which

问题 I have some code that is using Task<T> which defers returning a result from a serial read operation for a short time, like this: void ReturnResponseAfterAShortDelay() { if (delayedResponseCancellationTokenSource != null) delayedResponseCancellationTokenSource.Cancel(); // Cancel any pending operations and start a new one. delayedResponseCancellationTokenSource = new CancellationTokenSource(); log.InfoFormat("Deferring response for {0} ms", Settings.Default.TimeoutMs); Task.Delay(Properties

问题 My question is probably pretty basic but still I can't get a solution in the official doc. I have defined a Celery chain inside my Django application, performing a set of tasks dependent from eanch other: chain( tasks.apply_fetching_decision.s(x, y), tasks.retrieve_public_info.s(z, x, y), tasks.public_adapter.s())() Obviously the second and the third tasks need the output of the parent, that's why I used a chain. Now the question: I need to programmatically revoke the 2nd and the 3rd tasks if

问题 i want to start a task when a relay command is called, however i want to disable the button as long as that task is running take this example private ICommand update; public ICommand Update { get { if (update == null) { update = new RelayCommand( param => Task.Factory.StartNew(()=> StartUpdate()), param => true); //true means the button will always be enabled } return update; } } what is the best way to check if that task is running? here is my solution but not sure if its the best way class

问题 Hello I'm writing a WPF program that gets has thumbnails inside a ThumbnailViewer. I want to generate the Thumbnails first, then asynchronously generate the images for each thumbnail. I can't include everything but I think this is whats relevant Method to generate the thumbnails. public async void GenerateThumbnails() { // In short there is 120 thumbnails I will load. string path = @"C:\....\...\...png"; int pageCount = 120; SetThumbnails(path, pageCount); await Task.Run(() => GetImages(path,

问题 Could anyone please explain this, perhaps I'm missing something obvious. These 2 cases seem to be identical in behavior, and yet they are not. Case 1 : Start a Task with an async Action, that does some work for some time: var t = Task.Run(async () => { await Task.Delay(2000); }); A second task waits for the first one: var waitingTask = Task.Run(() => { t.Wait(); }); Wait for the second task: waitingTask.Wait(); Case 2 : Build a Task using the Task constructor, passing the same async Action :
