Nico Kruber created FLINK-7499: ---------------------------------- Summary: double buffer release in SpillableSubpartitionView Key: FLINK-7499 URL: https://issues.apache.org/jira/browse/FLINK-7499 Project: Flink Issue Type: Bug Components: Network Affects Versions: 1.3.2, 1.3.1, 1.2.1, 1.3.0, 1.1.4, 1.2.0, 1.1.5, 1.2.2, 1.4.0, 1.3.3 Reporter: Nico Kruber Assignee: Nico Kruber
{{SpillableSubpartitionView#releaseMemory()}} recycles its buffers twice: once asynchronously after the write operation and once in {{SpillableSubpartitionView#releaseMemory()}} after adding the write operation to the queue. 1) if {{SpillableSubpartitionView#releaseMemory()}} hits first and the buffer is recycled, the memory region may already be reused despite the pending write 2) If, for some reason (probably only in tests like {{SpillableSubpartitionTest#testConsumeSpillablePartitionSpilledDuringConsume()}}?), the buffer is retained and to be used in parallel somewhere else it may also not be available anymore or contain corrupt data. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
