Using a Commonj Work Manager to send Asynchronous HTTP calls


Using a Commonj Work Manager to send Asynchronous HTTP calls

To fix this issue I ended up cloning the DOM document used as a parameter. There must be some downstream code that has side effects on the parameter.

will help you Twisted framework is just the ticket for that. But if you don't want to take that on you might also use pycurl, wrapper for libcurl, that has its own async event loop and supports callbacks.

will help you If you used Feign in a GUI application, coroutines would come as great help even though Feign is a blocking API.
Coupled with a thread pool, coroutines can turn a blocking call into a suspending one from the perspective of the caller. Since blocking the GUI thread is out of the question, this is a great match. You retain the exact same sync programming model (a simple function call that returns the HTTP result) and yet you comply with the GUI thread restrictions.
code :
class MyActivity : AppCompatActivity(), CoroutineScope {
    lateinit var masterJob: Job
    override val coroutineContext: CoroutineContext
        get() = Dispatchers.Main + masterJob

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        masterJob = Job()
        this.launch {
            val github: GitHub = feignCall("https://api.github.com")
            val contributors = github.contributors("OpenFeign", "feign")
            findViewById<TextView>(R.id.about_text_view).text = contributors.toString()
        }
    }

    override fun onDestroy() {
       super.onDestroy()
       masterJob.cancel()
}

suspend inline fun <reified T> feignCall(url: String) = withContext(Dispatchers.Default) {
    Feign.builder().decoder(GsonDecoder()).target(T::class.java, url)
}
How To Know All Asynchronous HTTP Calls are Completed

How To Know All Asynchronous HTTP Calls are Completed

This might help you The most simple way would be to keep a count of how many requests are 'in flight'. Increment it for each request enqueued, decrement it at the end of the callback. When/if the count is 0, any/all requests are done. Using a semaphore or counting lock you can wait for it to become 0 without polling.
Note that the callbacks run on separate threads, so you must provide some kind of synchronization.
code :
public class WaitableCallback implements Callback {

  private boolean done;
  private IOException exception;

  private final Object[] signal = new Object[0];

  @Override
  public void onResponse(Call call, Response response) throws IOException {
      ...
      synchronized (this.signal) {
        done = true;
        signal.notifyAll();
      }
  }

  @Override
  public void onFailure(Call call, IOException e) {
    synchronized (signal) {
      done = true;
      exception = e;
      signal.notifyAll();
    }
  }

  public void waitUntilDone() throws InterruptedException {
    synchronized (this.signal) {
      while (!this.done) {
        this.signal.wait();
      }
    }
  }

  public boolean isDone() {
    synchronized (this.signal) {
      return this.done;
    }
  }

  public IOException getException() {
    synchronized (this.signal) {
      return exception;
    }
  }

}
for ( WaitableCallback cb : pendingRequests ) {
  cb.waitUntilDone();
}
// At this point, all requests have been processed.

I wish this help you Fortunately, k6 currently does not support asynchronous, or more generally, event loop.
You can read here for more details about how script execution.
