HttpCore 4.2: waiting release after 2.7 (and Commons IO 2.3)
Hello,
I thinks that is better to wait the release after JMeter 2.7 to upgrade
HttpComponents HttpCore to 4.2 (currently 4.1.4).
http://mail-archives.apache.org/mod_mbox/www-announce/201205.mbox/%3C1336239139.2137.34.camel%40ubuntu%3E
On http://www.apache.org/dist/httpcomponents/httpcore/RELEASE_NOTES.txt
"new asynchronous client and server side protocol handlers", seems
important for the Parallel Controller discussion.
With Commons IO 2.3, Java 1.6 is needed.
http://mail-archives.apache.org/mod_mbox/www-announce/201204.mbox/%3CCACZkXPznzeiMdT%3DU%3DcLR16G2CKJJUiGzrt501rBREk3aZYxq6A%40mail.gmail.com%3E
After JMeter 2.7 release, I will start the Java 1.6 conversion
(@override tags, System Tray Icon, etc.)
Any comments are welcome.

Yes, the I/O can be network I/O, but it is still synchronous; it uses
just the same code as in the main HTTP samplers.
The Asynch I/O provided by HttpCore is completely different; it uses NIO.

Perhaps, I'm confused in my mind.
When I've developed the parallel download of embedded resources, I have
used java.util.concurrent.Future object, and the javadoc says "A Future
represents the result of an asynchronous computation".
I believes that the result it's a Async HTTPSampler in HTTPSamplerBase,
and a I/O (input/ouput) in my mind may be a network I/O.

Huh?
AFAICT, we use the standard HTTPSampler sample() method in a separate thread.
We don't use Asynch I/O.

Perhaps, but from what I have read on the HC mailing list it's only
really necessary for very high numbers of parallel requests.

Because, perhaps, a httpcore 4.2 update may introduce some hidden bug
just before the release. But you are right, the update can be made
before release with some checks. I can do this if your are ok.

Basic async request is used in HTTPSamplerBase for parallel download of
embedded resources. Perhaps that is a opportunity to study the async
httpclient api for the parallel controller discussion (or embedded
resources)

Not sure why you suggest waiting.
Though of course we need to check that it is suitable for use with the
current HttpClient release.

I doubt we need to move to aynch. IO for that.
After all, we already support parallel requests in different threads.

We should only upgrade to IO 2.3 once we start needing 1.6 elsewhere,
rather than being forced to use 1.6 because of IO 2.3.
I don't think we make extensive use of Commons IO, so there is no
particular need to update it.
