------------------------------
Resolution: Fixed
> Client CacheListener receives a TOMBSTONE when user calls region.get
> --------------------------------------------------------------------
>
> Key: GEODE-1830
> URL: https://issues.apache.org/jira/browse/GEODE-1830
> Project: Geode
> Issue Type: Bug
> Components: client/server
> Reporter: Dan Smith
> Assignee: Dan Smith
>
> A user's CacheListener on the client can see a TOMBSTONE as the newValue in
> this specific configuration:
> * The region is created using ClientRegionShortcut.PROXY (not CACHING_PROXY)
> * The value on the server is a TOMBSTONE (the entry has been created and
> then destroyed)
> * The user does a key for the destroyed key.
> Looking at the code, the problem seems to be in LocalRegion.basicPutPart2.
> The code checks to see if entry.isTomstone is true:
> {code}
> protected long basicPutPart2(EntryEventImpl event, RegionEntry entry,
> boolean isInitialized, long lastModified,
> boolean clearConflict)
> {
> final boolean isNewKey = event.getOperation().isCreate();
> final boolean invokeCallbacks = !entry.isTombstone(); // put() is
> creating a tombstone
> {code}
> Unfortunately, if the client is using ClientRegionShortcut.PROXY, the code
> calling this is ProxyRegionMap.basicPut, which passes a *static* markerEntry
> object, which will always return false for isTombstone. So the listener is
> invoked, despite the check for entry.isTombstone.
