Subject [jira] [Commented] (HTTPCORE-302) setEntity should consume the old entity first
Date Thu, 26 Jul 2012 14:12:36 GMT

    [ https://issues.apache.org/jira/browse/HTTPCORE-302?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13423092#comment-13423092

Oleg Kalnichevski commented on HTTPCORE-302:

Ah. I think I did it because the new method was available in the 4.3 code line only. We can
certainly add a reference to it in SVN trunk. IllegalArgumentException in case the response
object being null should be reasonable, shouldn't it?

> The setEntity() method of HttpResponse makes it very easy to leak connections if used
without consuming the old entity first. I'm proposing the following enhancements:
> 1) add a Javadoc note to the setEntity() method of HttpResponse that says something like:
"Implementations might not consume an existing entity. Callers should consume any existing
entity before calling this method."
> 2) either add a consumeAndSetEntity() method to BasicHttpResponse which consumes an existing
entity before setting the reference, OR change the implementation of setEntity() to consume
any existing entity first. (My vote is for the later, although it will change existing behavior,
it shouldn't negatively impact any callers.)
> The reason for this improvement request is simply that I've been burned a few times by
calling setEntity() without first consuming the existing entity, and I think we could make
this more user friendly. I'm happy to submit a patch once we decide what should be done with
