Example 1 with Builder

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

the class DocumentNodeStoreBranchesTest method commitHookChangesOnBranchWithInterference.

        }
    }
    // 2) wait 6 sec
    LOG.info("after purge was triggered above, 'waiting' 6sec");
    c.waitUntil(c.getTime() + 6000);
    // 3) now in another 'session', do another merge - to change the head
    LOG.info("in another session, do some unrelated changes to change the head");
    NodeBuilder parallelBuilder = ns.getRoot().builder();

    // 4) now merge the first session - this should now fail
    LOG.info("now merge the original builder - this should cause not all children to be visited");
    ns.merge(rootBuilder, CompositeHook.compose(Arrays.<CommitHook>asList(new TestHook("p"), new TestHook("q"))), CommitInfo.EMPTY);
    DocumentNodeState root = ns.getRoot();
    for (int i = 0; i < NUM_NODES; i++) {
        NodeState child = root.getChildNode("child" + i);
        assertTrue(child.exists());
        assertEquals("test", child.getProperty("p1").getValue(Type.STRING));
    }
}

Example 2 with Builder

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

the class CacheConsistencyRDBTest method setUpConnection.

@Before
@Override
public void setUpConnection() throws Exception {
    dataSource = RDBDataSourceFactory.forJdbcUrl(URL, USERNAME, PASSWD);
    DocumentMK.Builder builder = new DocumentMK.Builder().clock(getTestClock()).setAsyncDelay(0);
    RDBOptions opt = new RDBOptions().tablePrefix("T" + Long.toHexString(System.currentTimeMillis())).dropTablesOnClose(true);
    store = new TestStore(dataSource, builder, opt);
    mk = builder.setDocumentStore(store).setLeaseCheck(false).open();
