[infinispan-issues] [JBoss JIRA] Updated: (ISPN-393) Override decodeLast instead of checking readableBytes

Override decodeLast instead of checking readableBytes ----------------------------------------------------- Key: ISPN-393 URL: https://jira.jboss.org/jira/browse/ISPN-393 Project: Infinispan Issue Type: Task Components: Cache Server Affects Versions: 4.1.0.ALPHA2 Reporter: Galder Zamarreno Assignee: Galder Zamarreno Fix For: 4.1.0.ALPHA3 Replace readableBytes hack when clients disconnect from the channel with implementing decodeLast accordingly. See below for more details <galderz> one final thing, <galderz> one thing I've spotted is that when a clients disconnect <trustin> (overriden that is) <galderz> my ReplayingDecoder.decode is called with nothing to read <galderz> iow, trying to read a byte throws a rather noisy ChannelClosedException or something like that <galderz> so, to get around this, <galderz> i created in the netty ChannelBufferAdapter that we have <galderz> i created a method called readableBytes that computes <galderz> buffer.writerIndex - buffer.readerIndex <trustin> hmmm <trustin> actually, ReplayingDecoder calls its decodeLast() method when the connection is closed. <galderz> calling buffer,readableBytes in the ReplayingDecoder would not really tell me what's behing <trustin> but the default implementation of decodeLast() is delegate the call to decode();. <galderz> right, so maybe I need to override decodeLast? <galderz> what I'm doing right now looks v hacky <trustin> yeah if you do not want to be notified when the connection is closed in your decoder <trustin> just override decodeLast() an do nothing there. <galderz> right, i'll check that out as well <trustin> The default decodeLast() implementation is reasonable with FrameDecoder, but I guess it seems to confuse the user with ReplayingDecoder * manik has quit (Quit: manik) <galderz> i think so, cos readableBytes gives me Integer.Max in those situations <trustin> when disconnected <trustin> readableBytes() will give the actual readable bytes <galderz> yeah, when disconnected <trustin> instead of Integer.MAX <galderz> it was definitely not giving me 0 <galderz> it was giving something really big <trustin> oh I see. <trustin> Let me know if you still have to problem after overriding decodeLast() <trustin> to -> the <galderz> sure, thanks a million for this chat
