use of org.apache.jackrabbit.oak.plugins.document.JournalGarbageCollector in project jackrabbit-oak by apache.

the class JournalIT method doLargeCleanupTest.

private void doLargeCleanupTest(int offset, int size) throws Exception {
    Clock clock = new Clock.Virtual();
    DocumentMK mk1 = createMK(0, /* clusterId: 0 => uses clusterNodes collection */

    // make sure we're visible and marked as active
    renewClusterIdLease(ns1);
    JournalGarbageCollector gc = new JournalGarbageCollector(ns1);
    clock.getTimeIncreasing();
    clock.getTimeIncreasing();
    // cleanup everything that might still be there
    gc.gc(0, TimeUnit.MILLISECONDS);
    // create entries as parametrized:

        mk1.commit("/", "+\"regular" + i + "\": {}", null, null);
        // always run background ops to 'flush' the change
        // into the journal:
        ns1.runBackgroundOperations();
    }
    // sleep 100millis
    Thread.sleep(100);
    // should now be able to clean up everything
    assertEquals(size, gc.gc(0, TimeUnit.MILLISECONDS));
