Timothy Bish resolved PROTON-1767. ---------------------------------- Resolution: Fixed Fixed by: https://github.com/apache/qpid-proton-j/commit/e7aae9469ac2f45a6de1822d7fe3cd2d4c8a314c > [proton-j] Allow the Transport to expose an output buffer that is not > read-only > ------------------------------------------------------------------------------- > > Key: PROTON-1767 > URL: https://issues.apache.org/jira/browse/PROTON-1767 > Project: Qpid Proton > Issue Type: Improvement > Components: proton-j > Affects Versions: proton-j-0.25.0 > Reporter: Timothy Bish > Assignee: Timothy Bish > Priority: Minor > Fix For: proton-j-0.26.0 > > > In some cases the read-only output buffer exposed by TransportImpl by calling > head() or getOutputBuffer() can lead to extra intermediate copies of the > buffer based on the IO framework being used to transmit the bytes (such as > current Netty releases). This is due to the fact that the read-only buffer > reports that it doesn't have a backing array so the frameworks try to work > around this to optimize the transfer of bytes. For uses who are aware of > this and can ensure they never tamper with the buffer contents that aren't > consumed we should let them choose to expose a writable duplicate of the > output buffer. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@qpid.apache.org For additional commands, e-mail: dev-h...@qpid.apache.org
