Flavio Junqueira commented on ZOOKEEPER-1197: --------------------------------------------- Camille, is setting the socket to linger an option here? > Incorrect socket handling of 4 letter words for NIO > --------------------------------------------------- > > Key: ZOOKEEPER-1197 > URL: https://issues.apache.org/jira/browse/ZOOKEEPER-1197 > Project: ZooKeeper > Issue Type: Bug > Components: server > Affects Versions: 3.3.3, 3.4.0 > Reporter: Camille Fournier > Assignee: Camille Fournier > Priority: Blocker > Fix For: 3.3.4, 3.4.0, 3.5.0 > > Attachments: ZOOKEEPER-1197.patch > > > When transferring a large amount of information from a 4 letter word, > especially in interactive mode (telnet or nc) over a slower network link, the > connection can be closed before all of the data has reached the client. This > is due to the way we handle nc non-interactive mode, by cancelling the > selector key. > Instead of cancelling the selector key for 4-letter-words, we should instead > flag the NIOServerCnxn to ignore detection of a close condition on that > socket (CancelledKeyException, EndOfStreamException). Since the 4lw will > close the connection immediately upon completion, this should be safe to do. > See ZOOKEEPER-737 for more details -- This message is automatically generated by JIRA.
