I.e., 3.0 provides a deep refactoring that address performance, concurrency
and scaling issues. Significant progress has been made towards the 3.0

It looks good. +1 on releasing this.
One comment might be to point people looking at the Java implementation
classes to the md files that provide the guided tutorial. I started in the

Hello,
I am wondering if anyone has looked into creating tree based algorithms for
multi-cast of RMI messages for river. Assuming a local cluster, such
patterns generally have log(p) cost for a cluster with p nodes.
For the curious, this is how many MPI messages are communicated under the
hood.
or river is not succeeding, but succeeding in a new
community.
Thanks,
Bryan

Sounds good. Does Apache do release candidates as well? If not,
let's make sure that the existing deployed footprint (which is large)
has a chance to evaluate the branch before the 3.0 release.

This is all good, but I would personally be interested in getting to a
release based on the QA branch with less remaining development. I would
suggest rapid iterations for releases with incremental change until a QA
branch based release is stable.

What is the argument for pushing out the qa_refactor based release? Do you
believe that it is not ready to evaluate in production systems? Or do you
believe that the rename is more important? If so, why? Just curious about
people's perspectives here.
Bryan

All you need to do is dup the buffer. That gives you independent fields for
position and limit, which is what is not thread safe. You do need a
synchronization section around that dup, but that is a very fast operation.
You can also use the read only view of the buffer. Bryan

If not. Let's just release it and document that there is a lot of churn. Give

We have been using river/jini since 2006. While I have very little time for
work on open source projects outside of our own (read - completely swamped), I
am hugely in favor of its continued life. The main points for me are not so

I would like to setup exporters used by both long-lived and relatively short
lived objects in a manner that could be compatible with a firewall. E.g., I
would like to have river communicating only using some configured ports. Is
this as easy as specifying the port number explicitly for TcpServ
y from the build
in eclipse?

Peter,
As I said, I am happy to take on a few classes and see if I can find some
problems or discuss possible concurrency failures. I am pretty good at
recognizing concurrency problems, at least within the range of coding
styles that I am familiar with. But I do not know the river internals.
Thi
I am uncomfortable with a release that has known concurrency problems. I
am also uncomfortable that the custom Levels serialization change by
Oracle [1] has broken the current release for new JVMs. I would like to
see a minor release which fixes that serialization problem and a candidate
release
Sure. Lets look at this more tomorrow. Bryan

We have a 10.8.2 on a recent intel mini with 16G RAM. Does the test suite
require much memory to run? If not, we also have some other machines with
less memory and earlier OS revisions.
Are there specific tests to run?
Any guidance on running the test suite?

I am curious whether there is any known problem where an interrupt could be
propagated into the wrong thread by the jini/river library (this is against
river 2.2), or perhaps retained across the reuse of a thread for another task.
