> StreamResultFuture check for completeness is inconsistent, leading to races
> ---------------------------------------------------------------------------
>
> Key: CASSANDRA-15667
> URL: https://issues.apache.org/jira/browse/CASSANDRA-15667
> Project: Cassandra
> Issue Type: Bug
> Components: Legacy/Streaming and Messaging
> Reporter: Sergio Bossa
> Assignee: Massimiliano Tomassi
> Priority: Normal
> Fix For: 4.0
>
>
> {{StreamResultFuture#maybeComplete()}} uses
> {{StreamCoordinator#hasActiveSessions()}} to determine if all sessions are
> completed, but then accesses each session state via
> {{StreamCoordinator#getAllSessionInfo()}}: this is inconsistent, as the
> former relies on the actual {{StreamSession}} state, while the latter on the
> {{SessionInfo}} state, and the two are concurrently updated with no
> coordination whatsoever.
> This leads to races, i.e. apparent in some dtest spurious failures, such as
> {{TestBootstrap.resumable_bootstrap_test}} in CASSANDRA-15614 cc
> [~e.dimitrova].
