Hi, I am trying to use jbosscache in the simplest way, having readers and writers working at the same time, with no transaction, just using the atomicity of operations replaceAll (writers) and getData (readers) on Node.
In my test case, 100 writers replace each second (or less) the complete data of a node using its own. Each second (or less) as well, 100 readers read that data, and verify its consistency (each value in the map is equal to the map size).
replaceAll and getData being atomic, I shouldn't have any reader complaining about consistencies, which is not what I found.
Here is my test case:
| package mytest;
|
| import java.util.HashMap;
| import java.util.Map;
| import java.util.Random;
|
| import junit.framework.TestCase;
|
| import org.jboss.cache.Cache;
| import org.jboss.cache.CacheFactory;
| import org.jboss.cache.DefaultCacheFactory;
| import org.jboss.cache.Fqn;
| import org.jboss.cache.Node;
|
| public class MyCacheTest extends TestCase {
|
| CacheFactory<Integer, Integer> factory;
|
| Cache<Integer, Integer> cache;
|
| Node<Integer, Integer> populations;
|
| int errors = 0;
|
| public void testCache() throws Exception {
| factory = new DefaultCacheFactory<Integer, Integer>();
| cache = factory.createCache();
| populations = cache.getRoot().addChild(Fqn.fromString("populations"));
|
| final Random r = new Random();
|
| for (int i = 0; i < 100; i++) {
| final Map<Integer, Integer> map = new HashMap<Integer, Integer>();
|
| for (int j = 0; j < i; j++) {
| map.put(j, i);
| }
|
| new Thread() {
| @Override
| public void run() {
| while (true) {
| populations.replaceAll(map);
| // System.out.println("replaceAll " + map.size());
| sleepRandom(r);
| }
| }
| }.start();
| }
|
| for (int i = 0; i < 100; i++) {
|
| new Thread() {
| @Override
| public void run() {
| while (true) {
| Map<Integer, Integer> map = populations.getData();
| int size = map.size();
|
| for (Integer value : map.values()) {
| if (value != size) {
| System.out.println("inconsistency in " + map);
|
| synchronized (MyCacheTest.this) {
| errors++;
| }
|
| break;
| }
| }
|
| sleepRandom(r);
| }
| }
| }.start();
| }
|
| Thread.sleep(10000);
| System.out.println("errors: " + errors);
| assertEquals(0, errors);
| }
|
| void sleepRandom(final Random r) {
| long sleep = 0;
| synchronized (r) {
| sleep = (long) (1000 * r.nextFloat());
| }
| try {
| Thread.sleep(sleep);
| } catch (InterruptedException e) {
| e.printStackTrace();
| }
| }
| }
|
Some runs do exhibit some inconsistencies, like the following, and some don't:
