Hello Developers

We at Dynasol are asked by Kennisnet to do some development/bugfixing for MMBob in the near future. They specifically requested that we should develop in the mmbase cvs repository, and build a specific Kennisnet release on top of the files produced by the mmbase contributions build.

A requirement for us is that we can make releases that can be reproduced. it should be possible to branch from a previous release. To document what changes belong to a specific release.

The trouble is that I can not think of a release model other than following the mmbase releases. Because the applications/contributions are dependent of mmbase and version tagging/branching follows mmbase.

It is not a very good situation if we fix a number of bugs and than have to say: you can have the new version in three weeks because than a new mmbase release is being made.

We could tag the mmbase repository for mmbob releases. This at least would give us the chance to recreate a release. The problem of this approach of course is that mmbase might at such a time be unstable itself.

So, the crux is that an independent development model for applications is completely missing. I can not think of a way to do it right. I suppose maven could be used to disconnect the applications/contributions from mmbase as it is good at defining dependencies. But that is not the current situation.

I wonder how other people look at this issue. is there something I miss?
Can anybody suggest a way of working that would allow us to meet hour requirements apart from following the mmbase releases?

I am looking forward to some reactions on this.

regards,

Ernst
