Subject [jira] [Created] (HTTPCORE-289) Cancellable#cancel() not invoked when network connection dies
Date Sun, 08 Jan 2012 16:29:39 GMT
Cancellable#cancel() not invoked when network connection dies

                 Key: HTTPCORE-289
                 URL: https://issues.apache.org/jira/browse/HTTPCORE-289
             Project: HttpComponents HttpCore
          Issue Type: Bug
          Components: HttpCore NIO
    Affects Versions: 4.2-alpha2
            Reporter: Geir Harald Hansen

I am rewriting my software to use the new API that comes with 4.2-alpha2. Returning a Cancellable
from HttpAsyncRequestHandler#handle() seems like a good idea for long running requests like
long polling. But I don't ever see Cancellable#cancel() being called.

I telnet into my server and type the necessary HTTP to start a long running request. A Cancellable
is created and returned from handle(). Then I kill the telnet process, thereby killing the
connection. I expect cancel() to be invoked in the connection's Cancellable at this point,
but nothing happens. cancel() is not invoked in my Cancellable, and there are no calls to
HttpAsyncServiceHandler#closed(), HttpAsyncServiceHandler#exception() or DefaultServerIODispatch#onClosed()
