Subject Re: [PATCH] Replace Component Classes with Service Equivalents
Date Wed, 25 Sep 2002 10:58:43 GMT
Following lots of discussion with regard to this change on james-dev
currently going on, I feel I need to -1 this change until at least the
next major release for Cornerstone (ie until 5.0), as it breaks backward
compatibility.

Rationale
---------
Some projects (ie JAMES) expose the ComponentManager interface, and
hence the Component interface, as part of their API, while also
depending on some of the cornerstone components and exposing these
through the ComponentManager by contract. Hence, removing Component and
ComponentManager from Cornerstone means that this client API breaks.

We should be supportive of our fellow developers at JAMES -- and any
other projects with a similar concern -- and give them the time to
handle this issue gracefully.

We should, however, formally deprecate the pieces in Cornerstone that
depend on the Component (& friends) interfaces, and indicate that they
will move to ServiceManager in the future, if we still want to continue
with this change.


Impact
------
This means that containers that want to be able to host the Cornerstone
components (ie Phoenix, Merlin) need to keep supporting
Component/Composable and friends. This is a good thing =)

best regards,

Leo Simons
