Vladimir Ershov commented on IGNITE-2509:
-----------------------------------------
Denis,
Thanks for checking! Could you please take a look at the test
GridCacheOffHeapValuesEvictionSelfTest that was added for preventing such cases
and advise about conf permutation for reproduction?
> Broken eviction and metrics for OFFHEAP_VALUES cache mode
> ---------------------------------------------------------
>
> Key: IGNITE-2509
> URL: https://issues.apache.org/jira/browse/IGNITE-2509
> Project: Ignite
> Issue Type: Bug
> Affects Versions: 1.5.0.final
> Reporter: Denis Magda
> Assignee: Denis Magda
> Priority: Blocker
> Fix For: 1.6
>
> Attachments: EvictionBug.java, eviction_fix.patch
>
>
> In case when {{OFFHEAP_VALUES}} mode is used {{EvictionPolicy}} calculates
> values size wrongly which leads to the fact that data is evicted only when
> either the limit on number of entries is reached or size of keys is bigger
> than max allowed size.
> To reproduce set the following cache configuration
> {noformat}
> FifoEvictionPolicy plc = new FifoEvictionPolicy();
> plc.setMaxMemorySize(2 * 1024 * 1024);
> cacheCfg.setEvictionPolicy(plc);
> cacheCfg.setMemoryMode(CacheMemoryMode.OFFHEAP_VALUES);
> cacheCfg.setSwapEnabled(true);
> {noformat}
> Test that reproduces the issue is attached.
> Also attached a patch that fixes the issue. However we should validate that
> the fix is full and add additional tests to the test suites.
> Finally, {{cache.metrics().getOffHeapAllocatedSize()}} always returns 0 for
> this cache mode. Has to be fixed as well.
