[jira] Commented: (DIRMINA-229) IoSessionOutputStream write methods
should not return before the I/O operation is fully completed
[ http://issues.apache.org/jira/browse/DIRMINA-229?page=comments#action_12424945 ]
Niklas Therning commented on DIRMINA-229:
-----------------------------------------
I think this problem is very bad since things could get very, very messed up if you wrap one of these stream instances in e.g. a BufferedOutputStream. I'm not sure whether we want non blocking writes here. If we use join() as suggested in Oleg's patch we could also check isWritten() on the WriteFuture and throw an IOException if it couldn't be written. WDYT?
BTW, the patch looks great. I have no objections. But I would like to add the isWritten() check as well. I'll go ahead and apply it right away.

> IoSessionOutputStream write methods return before the I/O operation is fully completed, which causes issues in protocol handlers based on blocking InputStream/OutputStream model. Is it a desired behaviour?
> Per discussion with Peter Royal on the HttpComponents mailing list I am working on a simple HTTP server based on MINA and HttpComponents Core. HttpCore does not work with the latest SVN snapshot of MINA without this patch (attached)
