All Implemented Interfaces:

public class TestIncrementalWrite
extends AbstractHTreeTestCase

Test suite for the logic performing incremental writes of nodes and leaves onto the store. The actual timing of evictions from the HardReferenceQueue is essentially unpredictable since evictions are driven by AbstractHTree#touch(AbstractNode) and nodes and leaves are both touched frequently and in a data and code path dependent manner.

Version:

$Id$ TODO The 2nd two tests in this file both rely on structural assumptions about the B+Tree. They will have to be carefully recrafted to work for the HTree. TODO There is an apparent problem with the persistence backed stress tests where incremental eviction can cause a parent directory page to become immutable during handling of addLevel(). The tests in this suite do not have the data scale necessary to trigger this issue. TODO This focuses on the reference counts and reference changes while TestDirtyIterators focuses on structural changes and the visitation patterns for children and post-order traversal both for all pages and for only dirty pages.
