Subject [jira] [Commented] (ACE-368) More than one version of a bundle can end up in a deployment package
Date Wed, 10 Jul 2013 14:21:49 GMT

Wilfried Sibla commented on ACE-368:
------------------------------------

What about preventing the client from checking in such a shop repository?
All artifacts and their symbolic names are known on deployment calculation and I assume that
it's possible to detect this collision.
May be it could be a solution to offer a check method in the client API which checks the calculated
deployment and returns a CheckResult.
If all is OK, the CheckResult is empty.
Otherwise the colliding artifacts are listed.
I would expect that we we will have such collisions quite often in our environment. Therefore
it would be more than good to have such a "collision detection"

> If you assign more than one version of a bundle to a target, for example by making two
static associations from the same feature, both will indeed end up in the deployment package.
It will then fail to install or roll back because the Deployment Admin implementation never
catered for this case and could not quite recover from it.
> However, the problem is created already in the client, because you should never be allowed
to end up with more than one version of a bundle. We probably need to discuss how to tell
the user about this and decide if we should a) simply refuse to deploy, b) choose the highest
version and drop the other or c) something else. :)
