[jira] [Commented] (FELIX-4598) BundleDependency can effectively track only one bundle

--------------------------------------

Hi Tuomas,

I have limited time since I'm travelling, going to vacations for two weeks, however I would like to point out that since a couple of months we have entirely revisited the dependency manager 4.0.0, using a new strong thread model.
And I'm not sure but I believe that this problem from dm 3.2.0 (if it is really a problem, I did not have time to really check) is probably not applicable in DM 4.0.0.

Unfortunately, we have not yet commited the DM 4.0.0 version in felix-trunk/dependencymanager, and you can take a look at the felix sandbox here: [1]: it's a pure bndtools project, so you will have to install bndtools before. But we will (hopefully) move this dm 4.0.0 soon to the felix-trunk.

then you can take a quick look at [2], which is a quick description about the new architecture, and the BundleDependencyImpl is located in [3] 

please close this issue if you think it's ok in DM 4.0.0. Thanks.

[3] http://svn.apache.org/viewvc/felix/sandbox/pderop/dependencymanager-prototype/org.apache.felix.dm/src/org/apache/felix/dm/impl/BundleDependencyImpl.java

PS: I will commit a fix as well as some test cases for your other issue FELIX-4594, but this will be committed in the dm 4.0.0 (in the sandbox).

> Bundles are delivered to callbacks after component is instantiated but prior to that they can't be. This is the case with ServiceDependencies as well but unlike them after component instantiation the tracker is not used as source of bundles but instead lookup method is used. {{ServiceDependencyImpl}} uses this approach only to gain properties and auto configuration instance.
> I suggest that {{BundleDependencyImpl#invokeAdded(DependencyService service)}} would be implemented in similar manner that {{ServiceDependencyImpl#invokeAdded(DependencyService service)}} has been (perhaps also utilizing the serial executor) .
