---------------------------------
Fix Version/s: 1.15.0
Resolution: Fixed
> PING message "leaked" at shutdown due to bad singleton implementation
> ---------------------------------------------------------------------
>
> Key: GEODE-9193
> URL: https://issues.apache.org/jira/browse/GEODE-9193
> Project: Geode
> Issue Type: Sub-task
> Components: native client
> Reporter: Blake Bender
> Assignee: Blake Bender
> Priority: Major
> Labels: pull-request-available
> Fix For: 1.15.0
>
>
> There is a micro-optimization in the native client to prevent creating and
> tearing down PING messages multiple times, since this message always has the
> same format. Unfortunately, the implementation uses a pointer, rather than a
> reference, so exactly one instance of TcrMessagePing is allocated on the
> heap, and the object is never deleted, making it appear as a leak in any
> leak-tracking tool.
> {code:java}
> TcrMessagePing* TcrMessage::getPingMessage(CacheImpl* cacheImpl) {
> static auto pingMsg = new TcrMessagePing(new
> DataOutput(cacheImpl->createDataOutput()), true);
> return pingMsg;
> } {code}
> Changing this from a pointer to a const reference will allow the object to be
> destructed properly at shutdown.
