            TaskQueue is used here to run task one by one

            It will run them one at a time, yes. SemaphoreSlim does have an implicit queue, but it's not strictly a FIFO-queue. Most synchronization primitives have a mostly-but-not-quite-FIFO implementation, which is Close Enough. This is because they are synchronization primitives, and not queues.

            If you want an actual queue (i.e., with guaranteed FIFO order), then you should use a queue, such as TPL Dataflow or System.Threading.Channels.

            if you trying to launch task without await inside it, it will block current thread.

            All async methods begin executing on the current thread, as described on my blog. async does not mean "run on a different thread". If you want to run a method on a thread pool thread, then wrap that method call in Task.Run. That's a much cleaner solution than sprinkling Task.Delay throughout, and it's more efficient, too (no delays).

            Enqueuing function to run after all events on current form are handled
            Asked 2022-Mar-15 at 03:25

            I have a form with a formdata event handler that updates a field of the FormData if a certain state is found in the DOM. After the form submission, the DOM needs to be changed, but the formdata event handler should still observe the old state. Currently, I achieve this by using setTimeout(() => {/*...*/}, 0) in a submit event handler on the same form, because this will enqueue the function to run later - hopefully, after the formdata event is handled. My question is: Is this behavior guaranteed, and if not, is there a specification-backed way to accomplish this behavior?

            In the specification of event loops, the first step for choosing what work to do next is described as:

            Let taskQueue be one of the event loop's task queues, chosen in an implementation-defined manner [...]

            The oldest task from this chosen queue is then run later on. This would mean, that if functions scheduled with setTimeout are in the same task queue as the event handlers and if the formdata event handler is scheduled before the submit handler is actually run, I would definitely be safe - I cannot find any evidence for that though. From the documentation of the formdata event ("fires after the entry list representing the form's data is constructed") and the fact, that the formdata handler is run after the submit handler, I would even assume the contrary to be true - but that is not what I observed with the approach described above.

            ...

            ANSWER

            Answered 2022-Mar-15 at 03:25

            Your understanding is quite correct, and you are right that setTimeout(fn, 0) may not always fire after a "related" event: it is indeed very possible that these events are fired from two different tasks, very unlikely they'll use the timer task sources, and you correctly identified the bit that would make the event loop "possibly" select a task from an other task source.

            However in this exact case, you are safe.

            The submit event and the formdata one are fired from the same "task"*.

            If you look at the form submit algorithm, you can see that the submit event is directly fired at step 6.5, instead of being wrapped in a task that would get queued like it's often the case.

            Let shouldContinue be the result of firing an event named submit at form [...]

            Then in the same algorithm, without any in parallel or anything implying asynchronicity, we have the step 8 that says

            Let entry list be the result of constructing the entry list with form, submitter, and encoding.

            And in this constructing the entry list algorithm, at the step 7, we have the call to

            Fire an event named formdata at form [...]

            once again without any asynchronicity allowed.

            So we can be sure that these events will fire without anything else in between (apart microtasks), and that your timer callback from the submit event will fire after the formdata callback, even two requestAnimationFrame callbacks scheduled in the same frame (that are also "synchronous" for the event loop) won't be able to interleave there:

            How do I run an asynchronous task periodically and also sometimes on demand?
            Asked 2022-Feb-15 at 22:43

            I have a task (downloading something from the Web) that runs regularly with pauses 10 min between runs.

            If my program notices that the data is outdated, then it should run the download task immediately unless it is already running. If the download task happened out-of-time, the next task should be after 10 min since the out-of-time task so all future tasks and pauses are shifted later in time.

            How do I do this with Tokio?

            I'd recommend using select! instead of interruptible futures to detect one of 3 conditions in your loop:

            • download task is finished
            • the data is outdated signal
            • data expired timeout signal

            "The data is outdated" signal can be conveyed using a dedicated channel.

            select! allows waiting for futures (like downloading and timeouts), and reading from channels at the same time. See the tutorial for examples of that.

            ANSWER

            Answered 2022-Jan-30 at 09:57

            I'd like to know by what criteria implementors run? How do they evaluate the "important-ness" of queues?

            That's basically their call, a design choice made from years of experience looking at how their tool is being used and what should be prioritized (and also probably a good part of common sense).

            The WHATWG indeed doesn't define at all how this task prioritization should be implemented. All they do is to define various task-sources (not even task-queues), to ensure that two tasks queued in the same source will get executed in the correct order.

            The closest we have of defining some sort of prioritization is the incoming Prioritized Task Scheduling API which will give us, web-authors, the mean to post prioritized tasks, with three priority levels: "user-blocking", "user-visible" and "background".

            To check what browsers actually implement, you'd have to go through their source-code and inspect it thoroughly.
            I myself already spent a couple hours in there and all I can tell you about it is that you better be motivated if you want to get the full picture.
            A few points that may interest you:

            • All browsers don't expose the same behavior at all.
            • In Chrome, setTimeout() still has a minimum delay of 1ms (https://crbug.com/402694)
            • In Firefox, because Chrome's 1ms delay was producing different results on some web-pages, they create a special very-low-priority task-queue only for the timers scheduled before the page load, the ones scheduled after are queued in a normal priority task-queue. (https://bugzil.la/1270059)
            • At least in Chrome, each task-queue has a "starvation" protection, which prevents said queue to flood the event-loop with its own task, by letting the queues with lower priority also execute some of their tasks, after some time (not sure how much).

            And in the end I'd like to see an example that shows the order of these queues, if it is possible.

            As hinted before, that's quite complicated, since there is no "one" order.

            Your own example though is quite a good test, which in my Chrome browser does show correctly that the UI task-queue has an higher priority than the timer one (the while loop takes care of the 1ms minimum delay I talked about). But for the DOMContentLoaded though, I must admit I'm not entirely sure it shows anything significant: The HTML parser is also blocked by the while loop and thus the task to fire the event will only get posted after the whole script is executed.

            But given this task is posted on the DOM Manipulation task source, we can check it's priority by forcing a other task that uses this task source, e.g script.onerror.
            So here is an update to your snippet, with a few more task sources, called in reverse order of what my Chrome's prioritization seems to be:

            Twilio developer evangelist here.

            The structure of your form and the data within it seem relatively arbitrary. I know it is based on whatever data that you get from the TaskRouter API, which will likely not change, but you do still have to render lists of form items. To that end I wrote up a quick experiment to see how you could solve this for any object that you can give a component. Hopefully this is helpful and you can apply it to your application.

            React's model is that data is sent down and actions bubble up, so in this case you want to store your form's state in the top level component, which also handles the form's submit event, and send that state down to the child components. The child components should then send up change events that update the state.

            Then, when the form is submitted, you can send the full state to the endpoint (side note here, we recommend that you implement calls to the Twilio API on the server side, not in the client, so that you don't embed your API credentials in the front-end where they can be taken). I note that your application doesn't currently have a

            element (that I can see), I do recommend you wrap form elements in a so that you can handle the submission of the with an onSubmit handler.

            The previous paragraph is the easy part, the harder part is keeping the state up to date. If you run your code as you have it, where a number of the inputs have a value attribute but not an onChange handler, you'll find React telling you that you need to do something about it.

            So, you need to implement an onChange handler that updates the state in the top level component. I had a go at implementing this myself, for an arbitrary object full of data. I created a handleUpdate function that could be passed to any input as an onChange handler. When the handleUpdate function is triggered, it is passed an event which points to the DOM element that triggered it. You can use this to get the value of the element to update your state:

            How does camel jms component consume messages from queue
            Asked 2021-Nov-18 at 17:01

            Our environment consists of 3 jboss servers(portal,jms,reconciliation).

            1. Reconciliation server hosts camel routes which has a Route consuming from queue(SLAQueue).
            2. JMS server has all our queues hosted.
            3. Recently we identified a bug where some of messages in TaskQueue hosted on JMS server are not being delivered to MDB's on portal server. For some reason they are stuck and when we restart the JMS server the stuck messages are delivered.

            To investigate we enabled TRACE level logging on "org.apache.activemq.artemis". We are noticing lot of chatter between our camel jms component and JMS server. One instance of chatter is listed below, logs like these get written every 1 second.

            Questions :

            1. What is the mechanism camel jms component uses to get messages from queue? Does JMS component poll the queue every second(pull) ? or JMS component gets notified when the message arrives in the queue ?
            2. Is the mechanism different from J2EE Message driven beans? The MDB' get notified when the message arrives in the queue.
            3. Based on the chatter below i think it is polling. If it is polling can the polling window be configured ? I have tried receiveTimeout option with no luck.

            Yes, the JMS consumers are polling. By default Camel uses Spring's DefaultMessageListenerContainer under the hood.

            The Spring-Listener itself uses the JMS API directly.

            Spring uses a default timeout of 1 second to pull messages. I don't know if you really can change this with Camel's receiveTimeout option.

            The answer lies in what is happening if this code executes while there is nothing in the queue.

            var workItem = await TaskQueue.DequeueAsync(stoppingToken);

            The answer is that nothing is happening. This line of code doesn't execute over and over again until something is dequeued. That's why there's no need for a delay.

            It also doesn't block until something is dequeued.

            What happens is that the thread executing the method is freed to do something else. No thread is dedicated to the execution of DequeueAsync. (See this excellent post - There Is No Thread.)

            When and if an item appears in the queue to be dequeued, then an available thread is assigned to resume execution of the method.

            DequeueAsync only throws an exception if

            • the cancellation token is canceled
            • the queue's Complete method is called and the queue is empty, which means that you're no longer expecting anything to appear in the queue.
