Subject RE: [Lucene.Net] Is a Lucene.Net Line-by-Line Jave port needed?
Date Thu, 30 Jun 2011 20:19:33 GMT
Michael,
You interpret the report as "whoever commits code wins"? But when I look at it, I see "a lof
of talk, no work". .Net community is not interested in contributing.
I really don't understand what hinders people to work on Lucene.Net. As I did for 2.9.4g,
grab the code, do whatever you want on it and submit back. If it doesn't fit to the project's
direction it can still find a place in contrib or in branch. All of the approaches can live
side by side happily in the Lucene.Net repository. 

Troy,
I also don't understand why do you wait for 2.9.4g? It is a *branch* and has nothing to do
with the trunk. It need not be an offical release and can live in branch as a PoC. 


As a result, I got bored to listen to "this should be done that way". What I want to see is
"I did it that way, should we continue with this".

Michael,

I agree with everything you said. My point in saying "whoever commits code
wins" was to illustrate the reality of how and why the project has the
current form.

Building consensus is difficult. It is an essential first step before we can
do something like make a list of bit-sized pieces of work that others can
work on.

This is why my real message of "Let's find a way to accommodate both" is so
important. It allows us to build consensus, so that we can settle on a
direction and structure our work.

Until we accomplish that, it really is "whoever commits code wins", and that
is an unhealthy and unmaintainable way to operate.

>From a technical perspective, your statements about the unit tests are
completely accurate. They really need a LOT of reworking. That's the very
first step before making any significant changes. Part of the problem is
that the tests themselves are not well written. The other part is that the
Lucene object model was not designed for testability, and it makes writing
good tests more difficult, and certain tests might not be possible. It will
be difficult to write good unit tests without re-structuring. The biggest
issue is the use of abstract classes with base behaviour vs interfaces or
fully abstracted classes. Makes mocking tough. This is the direction I was
going when I started the Lucere project. I'd like to start in on that work
after the 2.9.4g release.

Thanks,
Troy
