public class TestHistoryIndex
extends ProxyBigdataSailTestCase

Test the index supporting the HistoryServiceFactory.

Version:

$Id$ TODO The unit tests should cover both the tx and non-tx modes.

For read/write tx, we can not use an unisolated history index since changes could become committed before a given tx commits due to a concurrent tx commit. That would break the semantics of the history index if the tx then fails rather than committing since some of its changes would have become visible and durable anyway.

We might need a write-write conflict resolver for the history index when read-write tx are used. Otherwise a conflict on the history index could cause a tx to fail. I suspect that we can reconcile exactly the same write-write conflicts on the history index that we can reconcile on the statement indices, but this needs to be worked through in detail.

Method Detail

test_historyIndexDisabled

public void test_historyIndexDisabled()
                               throws org.openrdf.sail.SailException

Unit test verifies that the history index is not created if the option is not enabled.

Throws:

org.openrdf.sail.SailException

test_historyIndex01

public void test_historyIndex01()
                         throws org.openrdf.sail.SailException

Unit test works its way through two commit points, verifying the state changes in the history index in depth. In the first commit point, two statements are added and both should appear in the history index. In the second commit point, one of the statements is removed and an entry for that removal is also added to the history index.

Throws:

org.openrdf.sail.SailException

test_historyIndexWithPruning01

public void test_historyIndexWithPruning01()
                                    throws org.openrdf.sail.SailException

Unit test works its way through two commit points when the index pruning is set to 1 millisecond, verifying the state changes in the history index in depth. In the first commit point, two statements are added and both should appear in the history index. In the second commit point, one of the statements is removed and an entry for that removal is also added to the history index. However, both of the original entries in the history index have been aged out so they no longer appear.

Throws:

org.openrdf.sail.SailException
