Examples with GenWorkerImpl cz.metacentrum.perun.engine.scheduling.impl.GenWorkerImpl used on opensource projects

Example 1 with GenWorkerImpl

use of cz.metacentrum.perun.engine.scheduling.impl.GenWorkerImpl in project perun by CESNET.

the class GenWorkerImplTest method testGenWorkerSuccess.

@Test
public void testGenWorkerSuccess() throws Exception {
    GenWorker worker = new GenWorkerImpl(task1, null);
    Task resultTask = worker.call();
    LocalDateTime now = LocalDateTime.now();
    assertTrue(resultTask.getGenEndTime().isBefore(now) || resultTask.getGenEndTime().equals(now));
    // GenWorker itself doesn't change status anymore, since it caused race condition with endStuckTasks() process
    // Its now responsibility of GenCollector thread to switch status -> only genEndTime is set by worker.
    assertEquals(PLANNED, resultTask.getStatus());
}

Example 2 with GenWorkerImpl

use of cz.metacentrum.perun.engine.scheduling.impl.GenWorkerImpl in project perun by CESNET.

the class GenPlanner method run.

@Override
public void run() {
    BlockingDeque<Task> newTasks = schedulingPool.getNewTasksQueue();
    while (!shouldStop()) {
        try {
            log.debug("Getting new Task in the newTasks BlockingDeque");
            Task task = newTasks.take();
            /*
				!! Change status immediately, so it won't be picked by PropagationMaintainer#endStuckTasks()
				because we might be waiting on blockingSubmit() here !!
				*/
            task.setStatus(GENERATING);
            GenWorker worker = new GenWorkerImpl(task, directory);
            genCompletionService.blockingSubmit(worker);
            try {
                jmsQueueManager.reportTaskStatus(task.getId(), task.getStatus(), task.getGenStartTime().atZone(ZoneId.systemDefault()).toInstant().toEpochMilli());
            } catch (JMSException e) {
                log.warn("[{}] Could not send Tasks {} GEN status update: {}", task.getId(), task, e);
            }
        } catch (InterruptedException e) {
            String errorStr = "Thread executing GEN tasks was interrupted.";
            log.error(errorStr, e);
            throw new RuntimeException(errorStr, e);
        } catch (Throwable ex) {
            log.error("Unexpected exception in GenPlanner thread. Stuck Tasks will be cleaned by PropagationMaintainer#endStuckTasks() later.", ex);
        }
    }
}
