Examples with Tombstone org.apache.geode.internal.cache.Token.Tombstone used on opensource projects

Example 1 with Tombstone

use of org.apache.geode.internal.cache.Token.Tombstone in project geode by apache.

the class NewWANConcurrencyCheckForDestroyDUnitTest method verifyTimestampAfterOp.

/*
   * For VM 5 in ds 3.
   */
public static void verifyTimestampAfterOp(long timestamp, int memberid) {
    Region region = cache.getRegion("repRegion");
    assertEquals(0, region.size());
    Region.Entry entry = ((LocalRegion) region).getEntry("testKey", /* null, */
    true);
    RegionEntry re = ((EntrySnapshot) entry).getRegionEntry();
    assertTrue(re.getValueInVM((LocalRegion) region) instanceof Tombstone);
    VersionTag tag = re.getVersionStamp().asVersionTag();
    assertEquals(timestamp, tag.getVersionTimeStamp());
    assertEquals(memberid, tag.getDistributedSystemId());
}

Example 2 with Tombstone

use of org.apache.geode.internal.cache.Token.Tombstone in project geode by apache.

the class PersistentRVVRecoveryDUnitTest method testConflictChecksDuringConcurrentDeltaGIIAndOtherOp.

/**
   * This test creates 2 VMs in a distributed system with a persistent PartitionedRegion and one VM
   * (VM1) puts an entry in region. Second VM (VM2) starts later and does a delta GII. During Delta
   * GII in VM2 a DESTROY operation happens in VM1 and gets propagated to VM2 concurrently with GII.
   * At this point if entry version is greater than the once received from GII then it must not get
   * applied. Which is Bug #45921.
   *
