----------------------------------
Summary: let NettyBufferPool extend PooledByteBufAllocator
Key: FLINK-7517
URL: https://issues.apache.org/jira/browse/FLINK-7517
Project: Flink
Issue Type: Sub-task
Components: Network
Affects Versions: 1.4.0
Reporter: Nico Kruber
Assignee: Nico Kruber
{{NettyBufferPool}} wraps {{PooledByteBufAllocator}} but due to this, any
allocated buffer's {{alloc()}} method is returning the wrapped
{{PooledByteBufAllocator}} which allowed heap buffers again. By extending the
{{PooledByteBufAllocator}}, we prevent this loop hole and also fix the
invariant that a copy of a buffer should have the same allocator.
