Replacing entry via Memcached does not increment version of original HotRod entry --------------------------------------------------------------------------------- Key: ISPN-3164 URL: https://issues.jboss.org/browse/ISPN-3164 Project: Infinispan Issue Type: Bug Affects Versions: 5.3.0.CR1 Reporter: Martin Gencur Assignee: Galder Zamarreño Fix For: 5.3.0.Final When an entry is stored via HotRod and later replaced by Memcached (or Embedded, it does not matter), the version of the entry does not change. This makes operations like replaceWithVersion of HotRod client unreliable in compatibility mode. {code:java} public void testHotRodPutMemcachedReplaceHotRodGetVersionedTest() throws Exception { final String key1 = "6"; // 1. Put with Hot Rod RemoteCache<String, Object> remote = cacheFactory.getHotRodCache(); assertEquals(null, remote.withFlags(Flag.FORCE_RETURN_VALUE).put(key1, "v1")); VersionedValue oldValue = remote.getVersioned(key1); // 2. Replace with Memcached Future<Boolean> f = cacheFactory.getMemcachedClient().set(key1, 0, "v2"); assertTrue(f.get(60, TimeUnit.SECONDS)); // 3. Get with HotRod assertEquals("v2", remote.getVersioned(key1).getValue()); assertTrue("The entry version should have changed", oldValue.getVersion() != remote.getVersioned(key1).getVersion()); //^^^ fails here } {code}
