What's the concern about just using the prescribed branching pattern
for SVN? There are some other nice tricks like "externals" for pulling
in common files into the working copies of other branches (ala the
'concurrent' code in 'standard' that's pulled into 'enhanced' on
checkout).
Even the authors of SVN warn people away from using externals.
Yeah, and a nightmare when trying to 'tag' code -- copying the link to
HEAD is no help.
I would propose we at least attempt to go down a path of
investigating a branching.
We should consider everything, but I'd personally rather keep as few
codelines as possible.
Agreed.
Regardless, I think we need to settle on our exact requirement first,
before spending too much time on looking for a solution. For example,
if logging is a real requirement, but everyone agrees it can be done
via instrumentation (AspectJ, java.lang.instrument, etc), then are
there any other requirements that affect the actual source files
internally? If not, then could all of the other requirements be
fulfilled by judicious SCM use?
So, I would suggest we back up a little and just layout all of the
requirements first, so we can make sure everyone's in agreement about
the needs.
Nathan is right -- this is hypothetical now, unless (for example) we
start on Java 6 development now.
Exactly - we need use cases (and it's not clear that the logging
problems have been resolved w/ aspects yet...)
You're joking, right? I tease the aspect people that logging is the
only problem that has been solved(*) <g>. There are lots of references
on how to do that, eg:
http://www.developer.com/java/other/article.php/3109831
There's caching too, I think. LogCache4J
What I meant was that it didn't seem like we came to a conclusion on it
- that if we had a general pre-processing solution, we could use that
too for logging, rather than have two.
The actual use-cases will help figure this out.

(*) it's not true though, there are a number of tasks that are
well-suited to using aspects. However, I would use them judiciously.
Like caching :) (And get your local psychic retainer to tell you what
the code is doing... ;)
