Examples with BoundedServices reactor.core.scheduler.BoundedElasticScheduler.BoundedServices used on opensource projects

Example 1 with BoundedServices

use of reactor.core.scheduler.BoundedElasticScheduler.BoundedServices in project reactor-core by reactor.

the class BoundedElasticSchedulerTest method restartSupported.

@Test
public void restartSupported() {
    BoundedElasticScheduler s = scheduler();
    s.dispose();
    BoundedServices servicesBefore = s.boundedServices;
    assertThat(servicesBefore).as("SHUTDOWN").isSameAs(BoundedElasticScheduler.SHUTDOWN);
    s.start();
    assertThat(s.boundedServices).isNotSameAs(servicesBefore).hasValue(0);
}

Example 2 with BoundedServices

use of reactor.core.scheduler.BoundedElasticScheduler.BoundedServices in project reactor-core by reactor.

the class BoundedElasticSchedulerTest method startNoOpIfStarted.

@Test
public void startNoOpIfStarted() {
    BoundedElasticScheduler s = scheduler();
    // need a first call to `start()` after construction
    BoundedServices servicesBefore = s.boundedServices;
    s.start();
    s.start();
    s.start();
    assertThat(s.boundedServices).isSameAs(servicesBefore);
}

Example 3 with BoundedServices

use of reactor.core.scheduler.BoundedElasticScheduler.BoundedServices in project reactor-core by reactor.

the class BoundedElasticSchedulerTest method evictionForWorkerScheduling.

@Test
public void evictionForWorkerScheduling() {
    MockUtils.VirtualClock clock = new MockUtils.VirtualClock(Instant.ofEpochMilli(1_000_000), ZoneId.systemDefault());
    BoundedElasticScheduler s = afterTest.autoDispose(new BoundedElasticScheduler(2, Integer.MAX_VALUE, r -> new Thread(r, "eviction"), 60 * 1000, clock));
    s.start();
    BoundedServices services = s.boundedServices;
    Worker worker1 = afterTest.autoDispose(s.createWorker());
    assertThat(services).as("count worker 1").hasValue(1);
    assertThat(s.estimateSize()).as("non null size before workers 2 and 3").isEqualTo(1);
    Worker worker2 = afterTest.autoDispose(s.createWorker());
    Worker worker3 = afterTest.autoDispose(s.createWorker());
    assertThat(services).as("count worker 1 2 3").hasValue(2);
    assertThat(s.estimateSize()).as("3 workers equals 2 executors").isEqualTo(2);
    services.eviction();
    assertThat(s.estimateIdle()).as("not idle yet").isZero();
    clock.advanceTimeBy(Duration.ofMillis(1));
    worker1.dispose();

    clock.advanceTimeBy(Duration.ofMinutes(1));
    services.eviction();
    assertThat(s.estimateIdle()).as("idle for 1 minute and 10ms").isEqualTo(s.estimateBusy()).isEqualTo(s.estimateSize()).isZero();
