Eventmachine talk - Dec 2007 - EventMachine 0.10.0 released with support

All, please download and try EventMachine version 0.10.0, available now on
Rubyforge.

The release contains a variety of small features as noted in the ChangeLog,
and one large, important feature: EventMachine now can be run in pure Ruby,
without the need for a compiled extension.

Pure-Ruby mode joins the C++ extension as a fully-supported implementation
of EM. What that means is that the project commits to support all
functionality under both versions, with platform distinctions as documented.
The support commitment is that any EM program will run unchanged on either
implementation. At this time, the pure Ruby implementation passes all of the
unit tests, as does the C++ version.

See the file PURE RUBY in the distro for information on how to use this
feature. If anything is not clear, please ask here. You will notice that
performance and scalability are not as good with pure Ruby as with the C++
extension, but otherwise, all of your programs should work just the same.

There has been enough interest in a pure Ruby version of EM to generate talk
of forking the code base. Since this would be extremely destructive to the
project, and also to the commitment that all of you have made to it, I
intend to do everything in my power to prevent a fork. Part of the
motivation for the  current 0.10.0 release is to relieve the pressure for a
fork.

On the roadmap, the 0.11.0 release will add a third implementation, written
in Java, and intended for JRuby users. Of course, you can use the pure Ruby
implementation on JRuby right now. But as with the original C++ version,
performance and scalability are important enough to justify a distinct
implementation in Java. Again, the same support commitment holds for Java as
for pure Ruby and C++: any program written to the official EM APIs is
guaranteed to run on any of the three implementations.

Tremendous work, Francis! I''ve been using EM for the last 2 months on
a job where I work. It has behaved flawlessly. Thanks very much for
your efforts.

Maybe hemant will drop his pure-ruby reactor in backgrounDRb and jump
on board the EM train...

I offered him an opportunity to contribute it to EM. He wasn''t
interested.

Speaking of backgrounDRb, there''s been a lot of talk of providing an
evented
version of it for EM. Anyone interested in working on that?
