---------------------------------
Assignee: Konstantin Dudkov (was: Semen Boikov)
> IgniteCache.invokeAll returns empty result set in ATOMIC cache
> --------------------------------------------------------------
>
> Key: IGNITE-3955
> URL: https://issues.apache.org/jira/browse/IGNITE-3955
> Project: Ignite
> Issue Type: Bug
> Components: cache
> Affects Versions: 1.7
> Reporter: Pavel Tupitsyn
> Assignee: Konstantin Dudkov
> Fix For: 1.8
>
>
> When entry processor is invoked from multiple threads, result set is sometimes empty.
> This happens with ATOMIC cache, but not with TRANSACTIONAL.
> To reproduce, paste the following into GridCacheAbstractFullApiSelfTest.java:
> {code}
> public void testInvokeAllMultithreaded() throws Exception {
> final IgniteCache<String, Integer> cache = jcache();
> final int threadCnt = 4;
> final int cnt = 90000;
> final Set<String> keys = Collections.singleton("myKey");
> GridTestUtils.runMultiThreaded(new Runnable() {
> @Override public void run() {
> for (int i = 0; i < cnt; i++) {
> final Map<String, EntryProcessorResult<Integer>> res =
> cache.invokeAll(keys, new CacheEntryProcessor<String, Integer, Integer>() {
> @Override
> public Integer process(MutableEntry<String, Integer> entry,
> Object... objects) throws EntryProcessorException {
> Integer val = entry.getValue();
> if (val == null)
> val = 0;
> val++;
> entry.setValue(val);
> return val;
> }
> });
> assertEquals(1, res.size());
> }
> }
> }, threadCnt, "testInvokeAllMultithreaded");
> assertEquals(cnt*threadCnt, (int)cache.get("myKey"));
> }
> {code}
> Run this test as part of GridCacheAtomicFullApiSelfTest.java.
