Semen Boikov updated IGNITE-3299:
---------------------------------
Fix Version/s: (was: 2.3)
> Cache remove can be lost in ATOMIC cache with OFFHEAP_TIERED memory mode
> ------------------------------------------------------------------------
>
> Key: IGNITE-3299
> URL: https://issues.apache.org/jira/browse/IGNITE-3299
> Project: Ignite
> Issue Type: Bug
> Components: cache
> Reporter: Semen Boikov
> Assignee: Semen Boikov
>
> Added test reproducing issue (IgniteCacheConcurrentPutGetRemove).
> 1. There is an issue with 'deferredDelete' implementation - entry marked as
> 'deleted' can be evicted from cache, after this information about remove is
> lost (note: this can be reproduced not only in OFFHEAP_TIERED, but also in
> ONHEAP_TIERED mode with eviction policy, also this can also cause lost update
> in transactional cache on changing topology).
> 2. Looks like condition for removing from offheap in
> GridCacheMapEntry.innerUpdate is not correct:
> {noformat}
> if (op != GridCacheOperation.UPDATE && cctx.offheapTiered() &&
> hasValPtr) {
> boolean rmv = cctx.swap().removeOffheap(key);
> {noformat}
> It is possible that value was put in offheap, but 'hasValPtr' is false.
