Vladimir Steshin created IGNITE-28133:
-----------------------------------------
Summary: Failure on cache.get() at the eviction.
Key: IGNITE-28133
URL: https://issues.apache.org/jira/browse/IGNITE-28133
Project: Ignite
Issue Type: Improvement
Reporter: Vladimir Steshin
When the eviction enabled on an in-memory cache, an assertion may apper in paraller get() operation:
{code:java}
Caused by: java.lang.AssertionError: [link=337503] at org.apache.ignite.internal.processors.cache.persistence.evict.RandomLruPageEvictionTracker.getFragmentLink(RandomLruPageEvictionTracker.java:193) at org.apache.ignite.internal.processors.cache.persistence.evict.PageAbstractEvictionTracker.tailPageTrackingIdx(PageAbstractEvictionTracker.java:212) at org.apache.ignite.internal.processors.cache.persistence.evict.PageAbstractEvictionTracker.trackFragmentPage(PageAbstractEvictionTracker.java:199) at org.apache.ignite.internal.processors.cache.persistence.freelist.AbstractFreeList$WriteRowHandler.addRow(AbstractFreeList.java:215) at org.apache.ignite.internal.processors.cache.persistence.freelist.AbstractFreeList$WriteRowHandler.run(AbstractFreeList.java:172) at org.apache.ignite.internal.processors.cache.persistence.freelist.AbstractFreeList$WriteRowHandler.run(AbstractFreeList.java:159) at org.apache.ignite.internal.processors.cache.persistence.tree.util.PageHandler.writePage(PageHandler.java:313) at org.apache.ignite.internal.processors.cache.persistence.DataStructure.write(DataStructure.java:371) at org.apache.ignite.internal.processors.cache.persistence.freelist.AbstractFreeList.writeSinglePage(AbstractFreeList.java:714) at org.apache.ignite.internal.processors.cache.persistence.freelist.AbstractFreeList.insertDataRow(AbstractFreeList.java:603) at org.apache.ignite.internal.processors.cache.persistence.freelist.CacheFreeList.insertDataRow(CacheFreeList.java:74) at org.apache.ignite.internal.processors.cache.persistence.freelist.CacheFreeList.insertDataRow(CacheFreeList.java:35) at org.apache.ignite.internal.processors.cache.persistence.RowStore.addRow(RowStore.java:110) at org.apache.ignite.internal.processors.cache.IgniteCacheOffheapManagerImpl$CacheDataStoreImpl.createRow(IgniteCacheOffheapManagerImpl.java:1541) at org.apache.ignite.internal.processors.cache.GridCacheMapEntry$AtomicCacheUpdateClosure.update(GridCacheMapEntry.java:5059) at org.apache.ignite.internal.processors.cache.GridCacheMapEntry$AtomicCacheUpdateClosure.call(GridCacheMapEntry.java:4785) at org.apache.ignite.internal.processors.cache.GridCacheMapEntry$AtomicCacheUpdateClosure.call(GridCacheMapEntry.java:4470) at org.apache.ignite.internal.processors.cache.persistence.tree.BPlusTree$Invoke.invokeClosure(BPlusTree.java:3941) at org.apache.ignite.internal.processors.cache.persistence.tree.BPlusTree.invokeDown(BPlusTree.java:2247) at org.apache.ignite.internal.processors.cache.persistence.tree.BPlusTree.invoke(BPlusTree.java:2137) {code}
This happens because _IgniteCacheOffheapManagerImpl_ does unprotected (with no {_}readLock(){_}):
{code:java}
PageEvictionTracker#touchPage(long pageId):{code}
{code:java}
private void afterRowFound(@Nullable CacheDataRow row, KeyCacheObject key) throws IgniteCheckedException {
if (row != null) {
row.key(key);
// Reproduce helper cycle. Increase the iteration number to get higher concurrecy chance.
for (int i = 0; i < 1000000; ++i)
grp.dataRegion().evictionTracker().touchPage(row.link());
}
}{code}
