ZhaoYang updated CASSANDRA-14754: --------------------------------- Test and Documentation Plan: CI: [https://circleci.com/workflow-run/52fd4154-03d5-4c92-bc3f-1378bf490fc9] Status: Patch Available (was: In Progress) [patch|https://github.com/apache/cassandra/pull/480]: * added verification to stream state transition: ** Disallow stream state to leave final state (eg. complete, failed) ** Disallow changing stream state to early state, eg. from {{streaming}} to {{preparing}} will fail * remove unused {{StreamSession}} from {{StreamMessage.Serializer.deserialize}} > Add verification of state machine in StreamSession > -------------------------------------------------- > > Key: CASSANDRA-14754 > URL: https://issues.apache.org/jira/browse/CASSANDRA-14754 > Project: Cassandra > Issue Type: Task > Components: Legacy/Streaming and Messaging > Reporter: Jason Brown > Assignee: ZhaoYang > Priority: Normal > Fix For: 4.0 > > > {{StreamSession}} contains an implicit state machine, but we have no > verification of the safety of the transitions between states. For example, we > have no checks to ensure we cannot leave the final states (COMPLETED, FAILED). > I propose we add some program logic in {{StreamSession}}, tests, and > documentation to ensure the correctness of the state transitions. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: commits-unsubscr...@cassandra.apache.org For additional commands, e-mail: commits-h...@cassandra.apache.org
