The SoftIndexFileStore runs into a deadlock at startup if more than ~20000 values have been stored and max node size is > 32777 bytes ------------------------------------------------------------------------------------------------------------------------------------- Key: ISPN-8912 URL: https://issues.jboss.org/browse/ISPN-8912 Project: Infinispan Issue Type: Bug Components: Loaders and Stores Affects Versions: 9.1.6.Final Reporter: Andreas Pabst Assignee: Radim Vansa The following unit test just puts lots of entries into the cache and restarts the cache repeatedly. It succeeds if maxNodeSize is set to anything up to 32777, but runs into a deadlock from 32778 upwards. If going even higher it doesn't run into a deadlock anymore, but throws an IllegalArgumentException instead. As a workaround one can delete the index. But the problem resurfaces after the next restart. {code:java} import java.util.concurrent.TimeUnit; import java.util.stream.IntStream; import org.infinispan.Cache; import org.infinispan.configuration.cache.Configuration; import org.infinispan.configuration.cache.ConfigurationBuilder; import org.infinispan.manager.DefaultCacheManager; import org.infinispan.manager.EmbeddedCacheManager; import org.infinispan.persistence.sifs.configuration.SoftIndexFileStoreConfigurationBuilder; import org.junit.After; import org.junit.Before; import org.junit.Rule; import org.junit.Test; import org.junit.rules.Timeout; public class SifsLargeNodeTest { private EmbeddedCacheManager cacheManager; @Rule public Timeout timeout = new Timeout(15, TimeUnit.SECONDS); private static Configuration createConfig(String location, int maxNodeSizeInBytes) { return new ConfigurationBuilder() .persistence().addStore(SoftIndexFileStoreConfigurationBuilder.class) .dataLocation(location + "/data").indexLocation(location + "/index") .maxNodeSize(maxNodeSizeInBytes) .preload(false).purgeOnStartup(false) .build(); } @Before public void setUp() { cacheManager = new DefaultCacheManager(); } @After public void tearDown() { cacheManager.stop(); } @Test public void testLoad() { int maxNodeSizeInBytes = 32780; // Note: Anything up to 32777 works fine String cacheName = "sifslargenodetestcache"; Configuration cfg = createConfig(cacheName, maxNodeSizeInBytes); int numberOfRuns = 10; int valuesToPutPerRun = 10000; for (int run = 0; run < numberOfRuns; run++) { System.out.println("RUN " + run); cacheManager.defineConfiguration(cacheName, cfg); Cache<Integer, String> testCacheBeforeReduction = cacheManager.getCache(cacheName); IntStream.range(run * valuesToPutPerRun, (run + 1) * valuesToPutPerRun) .forEach(i -> testCacheBeforeReduction.put(i, Integer.toString(i))); cacheManager.stop(); cacheManager = new DefaultCacheManager(); } } } {code}
