Summary: Failed Compare and Swap in SASI's DataTracker#update Can Lead to Improper Reference Counting of SSTableIndex Key: CASSANDRA-14207 URL: https://issues.apache.org/jira/browse/CASSANDRA-14207 Project: Cassandra Issue Type: Bug Components: sasi Reporter: Jordan West Assignee: Jordan West Attachments: sasi-invalid-reference-count.rtf A race between e.g. Index Redistribution and Compaction can cause the compare and swap of a new {{sasi.conf.View}} in {{sasi.conf.DataTracker#update}} to fail, leading to recreation of the view and improper reference counting of an {{SSTableIndex}}. This is because the side-effects (decrementing the reference count via {{SStableIndex#release}}) occur regardless of if the view is promoted to be the active view. Code: https://github.com/apache/cassandra/blob/cassandra-3.11.1/src/java/org/apache/cassandra/index/sasi/conf/DataTracker.java#L72-L78 Attached logs and debug output show case where index redistribution and compaction race. This case was generated using the test provided in https://issues.apache.org/jira/browse/CASSANDRA-14055 -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: commits-unsubscr...@cassandra.apache.org For additional commands, e-mail: commits-h...@cassandra.apache.org
