May be you should try something like ant’s replaceregexp: task myCopy << { ant.replaceregexp(match:’aaa’, replace:’bbb’, flags:’g’, byline:true) { fileset(dir: ‘src/main/java/android/app/cfg’, includes: ‘TestingConfigCopy.java’) } } This task will replace all occurances of aaa with bbb. Anyway, it’s just an example, you can modify it under your purposes or try some similar solution with ant.
The problem is in this line: return new Action(async () => … You start an async operation with the async lambda, but don’t return a task to await on. I.e. it runs on worker threads, but you’ll never find out when it’s done. And your program terminates before the async operation is complete -that’s why … Read more
EDIT as of this article from MSDN: Both Parallel and Task are wrappers for ThreadPool. Parallel invoke also awaits until all tasks will be finished. Related to your questions: Using Task, Parallel or ThreadPool depends on the granularity of control you need to have on the execution of your parallel tasks. I’m personally got used … Read more
When you say await task.ConfigureAwait(false) you transition to the thread-pool causing mapping to run under a null context as opposed to running under the previous context. That can cause different behavior. So if the caller wrote: await Map(0, i => { myTextBox.Text = i.ToString(); return 0; }); //contrived… Then this would crash under the following … Read more
SemaphoreSlim maxThread = new SemaphoreSlim(10); for (int i = 0; i < 115; i++) { maxThread.Wait(); Task.Factory.StartNew(() => { //Your Works } , TaskCreationOptions.LongRunning) .ContinueWith( (task) => maxThread.Release() ); }
Note: The following applies to VS2010 and publishing web-application projects with the “Web Deploy” publish method selected in the ‘Build/Publish {projectname}’ dialog. Julien Hoarau’s correct in that “Publish” is NOT the name of the msbuild target invoked in the above case; the actual target name is “MSDeployPublish”. Therefore, you have to define a “Target” element … Read more
Actually, the accepted answer mocks a synchronous exception being thrown, that is not the real async behavior. The correct way to mock is: var myService = Substitute.For<IMyService>(); myService.GetAllAsync() .Returns(Task.FromException<List<object>>(new Exception(“some error”))); Let’s say you had this code and GetAllAsync() try { var result = myService.GetAllAsync().Result; return result; } catch (AggregateException ex) { // whatever, do … Read more
Task.Wait() waits up to specified period for task completion and returns whether the task completed in the specified amount of time (or earlier) or not. The task itself is not modified and does not rely on waiting. Read nice series: Parallelism in .NET, Parallelism in .NET – Part 10, Cancellation in PLINQ and the Parallel … Read more
In general thread pooling, you distinguish short-running and long-running threads based on the comparison between their start-up time and run time. Threads generally take some time to be created and get up to the point where they can start running your code. The means that if you run a large number of threads where they … Read more
In a nutshell, Automatic Task Killers work by polling the OS for a list of currently running processes and the memory they are consuming. Then either with an intelligent algorithm or with user input the Task Killers issue a call to the system telling the system to kill the process. There are two apis you … Read more
