[jira] [Reopened] (HTTPCORE-289) Cancellable#cancel() not invoked
when network connection dies
[ https://issues.apache.org/jira/browse/HTTPCORE-289?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Geir Harald Hansen reopened HTTPCORE-289:
-----------------------------------------
4.2-beta1 downloaded from the website fails with the attached Test.java code. I'm pretty sure this was working with an SVN snapshot at one point.
Do an HTTP request (with telnet, GET, or similar) and kill the process. The cancel() method is still not invoked until the timeout.

> 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() either.
