executioncontext

I have some synchronous calls in my Scala code. I've wrapped them in a blocking() context and then in a Future: Future(blocking(syncCall())), but I don't know which type of ExecutionContext to use. I know there may be a lot of possibilities and that there is not an ExecutionContext that it's the "best". I just need some information in order not to choose the worst because there is a lot of information out there and I have a mess in my head. 来源： https://stackoverflow.com/questions/38014748/best-executioncontext-for-io

I am trying to discover how the ExecutionContext actually works in version 4.0 and above of the .NET Framework. The documentation says that the managed principle, synchronization, locale and user context all flow to the new thread when using Thread.Start and most thread pool operations. But I cannot see this working at all in practice. Here is a simple console application that tests if the synchronization context and managed principle flow when starting a new thread... static void Main(string[] args) { SynchronizationContext.SetSynchronizationContext(new SynchronizationContext()); Thread

A new execution context is created for each function in JavaScript. How many execution contexts are present in memory when the following code is run? Note that function Bar is not invoked. function Foo () { function Bar() {} } Foo(); Also, when are the execution contexts created? At evaluation time or runtime? The runtime invocation of a function is what causes an execution context to be created. In your example, therefore, there's only one function call, so only one execution context is involved. The static (compile-time) arrangement of functions is important, because that determines scope

I'm having problems with my Playframework application not being responsive from time to time and I would like to detect this at runtime + log information on what is currently running on the exhausted execution context. What would the best strategy for implementing this be? I thought about posting small runnables to the execution contexts and if they don't get executed in time I would log a warning. This max wait time should of course be configurable. Eg the main web execution context should never be blocked for more than 1 sec but a background db execution context might allow 30 sec of

Would using Thread.CurrentPrincipal's claims in a referenced library that uses ConfigureAwait(false) pose any problems or will the flowing of ExecutionContext's logical call context take care of me there? (my reading and testing so far indicates that it will). Example WebAPI Controller Action: [CustomAuthorizeThatSetsCurrentUsersClaimsToThreadCurrentContextAndHttpContextCurrentUser] public async Task<Order> Get(int orderId) { return await _orderBusinessLogicLibrary.LoadAsync(orderId); // defaults to .ConfigureAwait(true) } Example load functions from external, referenced library:
