Examples with RetrySchema io.helidon.common.reactive.RetrySchema used on opensource projects

Example 1 with RetrySchema

use of io.helidon.common.reactive.RetrySchema in project helidon by oracle.

the class ReadableByteChannelPublisherTest method negativeDelay.

@Test
void negativeDelay() throws Exception {
    PeriodicalChannel pc = createChannelWithNoAvailableData(10, 1);
    RetrySchema schema = (i, delay) -> i >= 3 ? -10 : 0;
    ReadableByteChannelPublisher publisher = new ReadableByteChannelPublisher(pc, schema);
    // assert
    try {
        ContentReaders.readBytes(publisher).get(5, TimeUnit.SECONDS);
        fail("Did not throw expected ExecutionException!");
    } catch (ExecutionException e) {
        assertThat(e.getCause(), instanceOf(TimeoutException.class));
    }
}

Example 2 with RetrySchema

use of io.helidon.common.reactive.RetrySchema in project helidon by oracle.

the class ReadableByteChannelPublisherTest method onClosedInProgress.

@Test
@Disabled("This test uses a sleep, so could cause issues on slow environments")
void onClosedInProgress() throws Exception {
    PeriodicalChannel pc = createChannelWithNoAvailableData(5, 2);
    RetrySchema schema = RetrySchema.constant(TimeUnit.SECONDS.toMillis(2));
    ReadableByteChannelPublisher publisher = new ReadableByteChannelPublisher(pc, schema);
    // start reading (this will cause 2 second delay)
    Single<byte[]> data = ContentReaders.readBytes(publisher);
    // run the stream
    data.thenRun(() -> {
    });
    Thread.sleep(1000);
    // immediately close the channel, so we fail reading
    pc.close();
    CompletionException c = assertThrows(CompletionException.class, () -> data.await(5, TimeUnit.SECONDS));
    assertThat(c.getCause(), instanceOf(ClosedChannelException.class));
    LazyValue<ScheduledExecutorService> executor = publisher.executor();
    assertThat("Executor should have been used", executor.isLoaded(), is(true));
    assertThat("Executor should have been shut down", executor.get().isShutdown(), is(true));
