William R. Speirs commented on HTTPCORE-302:
--------------------------------------------
I'm guessing changing BasicHttpResponse.setEntity() to call
EntityUtils.consumeQuietly() would be out of the question? Could also extend
HttpResponse to have a version of setEntity(boolean consumeOldEntity), and keep
the behavior of setEntity() to NOT consume the entity.
I would be against adding another class (MessageUtils), unless there are other
such methods you'd like to see added but don't have a good home for. I'd rather
see it added to EntityUtils as updateEntity().

> Key: HTTPCORE-302
> URL: https://issues.apache.org/jira/browse/HTTPCORE-302
> Project: HttpComponents HttpCore
> Issue Type: Improvement
> Components: HttpCore
> Affects Versions: 4.2.1
> Reporter: William R. Speirs
> Fix For: 4.3
>
>
> 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 #2.
