----------------------------------
Summary: allow actual 0-length content in
NettyMessage#allocateBuffer()
Key: FLINK-7515
URL: https://issues.apache.org/jira/browse/FLINK-7515
Project: Flink
Issue Type: Sub-task
Components: Network
Affects Versions: 1.4.0
Reporter: Nico Kruber
Assignee: Nico Kruber
Priority: Minor
Previously, length {{0}} meant "unknown content length" but there are cases
where the actual length is 0 and we do not need a larger buffer. Let's use
{{-1}} for tagging the special case instead.
