IdHashShardingStrategy fails after 1.7M id is generated ------------------------------------------------------- Key: HSEARCH-237 URL: http://opensource.atlassian.com/projects/hibernate/browse/HSEARCH-237 Project: Hibernate Search Issue Type: Bug Affects Versions: 3.0.0.GA Reporter: Rafal Glowacz Assignee: Sanne Grinovero Original Estimate: 30 minutes Remaining Estimate: 30 minutes public class IdShardingStrategyTest extends TestCase { private IdHashShardingStrategy _defaultIdStrategy; private IdShardingStrategy _idStrategy; protected void setUp() throws Exception { _idStrategy = new IdShardingStrategy(); _idStrategy.initialize(null, createDirectoryProviders()); _defaultIdStrategy = new IdHashShardingStrategy(); _defaultIdStrategy.initialize(null, createDirectoryProviders()); } private DirectoryProvider[] createDirectoryProviders() { return new DirectoryProvider[]{new MockDirectoryProvider(), new MockDirectoryProvider(), new MockDirectoryProvider()}; } public void testIdSharding() { long id = 1; long limit = 1000 * 1000000 * 1000000L; try { while (id < limit) { generateForAddition(_idStrategy, id); generateForDeletion(_idStrategy, id); id += 129653153; } } catch (Exception e) { fail("Couldn't get directory for id " + id); } } public void testIdHashSharding() { long id = 1; long limit = 1000 * 1000000 * 1000000L; try { while (id < limit) { generateForAddition(_defaultIdStrategy, id); generateForDeletion(_defaultIdStrategy, id); id += 129653153; } fail("Should fail with ArrayIndexOutOfBoundsException for long id"); } catch (Exception e) { } } private MockDirectoryProvider generateForAddition(IndexShardingStrategy strategy, long id) { return (MockDirectoryProvider) strategy.getDirectoryProviderForAddition(null, id, id + "", null); } private DirectoryProvider[] generateForDeletion(IndexShardingStrategy strategy, long id) { return strategy.getDirectoryProvidersForDeletion(null, id, id + ""); } } Workaround: Returned value is minus for id's bigger then 1.7M so for time being I added check like: return value < 0 ? -1 * value : value; Works fine for me.
