---------------------------------
Assignee: marco polo
> Memory possibly lost by using new thread
> ----------------------------------------
>
> Key: MINIFI-214
> URL: https://issues.apache.org/jira/browse/MINIFI-214
> Project: Apache NiFi MiNiFi
> Issue Type: Sub-task
> Components: C++
> Reporter: marco polo
> Assignee: marco polo
> Fix For: cpp-0.2.0
>
>
> Several components ( the scheduling agents, and the provenance repository )
> create a new thread. We should not be doing this. If the flow of events is
> such that all closures occur, this "possibly lost" isn't a given; however, we
> can't guarantee all operations will occur in the negative paths.
> Further, it appears as though if a the agents are relying on closure from the
> flow controller to stop all threads. If we were to stop processing in a
> processing group as a result of a C2C operation ( for example ), the threads
> would be deleted from the list of known threads, but not stopped. Since they
> are detached, this could be a problem and allow the thread to continue in
> perpetuity. Depending on ulimit, this could cause complete failure.
> Finally, we should probably not detach threads and instead create
> std::packaged_tasks from which we can keep track of futures.
