Flight's zero-copy optimization was not enabled previously due to an oversight. Additionally, enabling it exposed a use-after-free of a direct Netty ByteBuf that manifested as SIGSEGV. This fixes both issues: the fast path is truly enabled, and to avoid the use-after-free, the lifetimes of Netty ByteBufs in the Flight gRPC marshaller is now tied to the ArrowBuf lifetimes. Finally, an environment variable + property are added to disable the fast path in case the old behavior is desirable. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
