Tabled Discussions

This document is to keep track of discusstion points related to Avalon 5 development. When things get to a point where they can be focused on in the Avalon-Dev site without being considered noise. Just follow the format already outlined below.

Should we incorporate Commons Logging?

This move would increase synergy with other projects and reduce the amount of code that we need to maintain. The issue was raised by Mauro Telivi, and we need further communication to figure out what is the best solution.

Update by LSD

Additional discussion as part of the framework 4.1.4 release. We didn't add a wrapper around commons-logging Log class, but it is easy to do and should be considered again for the next release.

Its turned out we cannot really migrate to Log at all in 4.x, as it doesn't provide getChildLogger(). And it makes no sense for commons either to add in that method into the Log interface (because of backwards compatibility).

Note discussions about this with commons were quite fun and productive, so good synergy vibes nonetheless :D

Topic: Should we use Maven for the build?

Our current build architecture is chaotic to say the least. We have no less than three methods of generating documentation, and serveral fairly complex build scripts. Maven helps smooth out the inconsistencies in the approach, and still allows for plugging in a documentation building tool like Fortress. Most importantly, it will get rid of many JAR files in our CVS directory, and simplify the build process for our users.

=== Update by LSD ====

We've started restructuring the build structure to get rid of jars in CVS by using standard ant tasks to get stuff from the maven repo. We've come a large way for generating docs (now using forrest in most places, still anakia in some, but no "custom cocoon" anymore).

The build structure is still quite complex and inconsistent. Its still a good idea to move away from "just ant". Jason suggested we wait for beta9 if we want to move.

CON:

  - speed (not a great problem in CVS version because of      "console" plugin)    - project inheritance is not fully done so we have to      copy a 3 line property file around when we are using;      however, this is supposed to be fixed before next release    - inheritance of maven.xmls is not possible as far as I      know so you can end up copying some around.  Not sure      if this will be fixed .. but will become irrelevent if      next point picked up ...    - painful to manage your own plugins if not in maven CVS.      I believe this will hopefully be fixed sometime in the      future ... maybe :) 

I am using their last release and it seems to work well. However it may be best to wait till next release before converting Avalon (Just to avoid a few bugs that the last Maven has). However I suggest we keep our current ANT build system around until Maven gets the ability to easily install plugins on per project basis at which point we can dump our exisitng build system.

Topic: Should we unify the CVS structures?

We currently have ~9 CVS structures. The purpose was to separate the different projects and make it very clear what code belongs to which project. That project also helps us identify areas of tight coupling and what projects depend on which other projects. That can still be done in one CVS structure, using directories to distinguish the projects.

Update by LSD

Well, testlet allready nuked, and we want to keep avalon, avalon-site and avalon-sandbox even if we do a unification, so definately not one repo. Doesn't apply to a SVN setup though.

PRO:

CON:

our asses off, and it has led to headaches where phoenix depended via-via on sandbox code and stuff like that. We've done enough restructuring.

update!

Topic: Should we remove unused sets of code?

Excalibur is rife with obsolete, competing, and confusing stuff. Also mixed in there are some *really* useful gold nuggets. By getting rid of the failed experiments, we can focus our energies and web site on what is good.

Update by LSD

General consensus seems to be: yes, we should. Excalibur is looking a lot cleaner already!
