Pierre De Rop commented on FELIX-4294:
--------------------------------------
The org.apache.felix.dm package version should now be bumped to 3.1.0 instead
of 3.0.0, because the ComponentDeclaration interface has been modified with the
following (API compatible) methods, in order to be able to implement this
FELIX-4294 new feature.
{code}
+ /** Returns the class name of the Component implementation. */
+ public String getClassName();
+ /** Returns the service optionally provided by this component, or null */
+ public String[] getServices();
+ /** Returns the service properties, or null */
+ public Dictionary getServiceProperties();
+ /** Returns the instance id of this component. */
+ public long getId();
{code}
So, in the core/pom.xml, I'm now exporting org.apache.felix.dm package to 3.1.0
instead of 3.0.0:
{code}
<Export-Package>org.apache.felix.dm;version="3.1.0";provide:=true,org.apache.felix.dm.tracker;version="3.1.0";provide:=true</Export-Package>
{code}
> Dependency Manager Shell improvements

> Project: Felix
> Issue Type: Improvement

>
> This issue proposes two enhancements regarding the dependency manager shell.
> 1) display component names more consistently
> =====================================
> - some components are sometimes displayed with a "class " prefix, while
> others are not:
> class org.amdatu.multitenant.adapter.TenantAdapter registered
> org.amdatu.multitenant.adapter.BundleDataStore(org.amdatu.tenant.pid=org.amdatu.tenant.PLATFORM,bundle.id=18)
> registered
> For readability, the "class " could be just removed.
> - When a component does not contain any service properties, an empty "()" is
> displayed after the component name
> pierre.multitenant.both.Both() registered
> org.amdatu.multitenant.TenantLifeCycleListener(org.amdatu.tenant.binding=3)
> registered
> As in previous case and for readability, it makes sense to not append an
> empty "()" after the component name, if it has no properties.
> 2) add "filter" and "nofilters" options for filter displayed components
> =====================================================
> By default, the "dm" shell command dumps all components. But sometimes, it
> is desirable to display a subset of all components,
> using a regular expression on the component name or on the component service
> properties.
> We can of course do this using gogo shell "grep", but the problem is that we
> may miss some important informations, like the component bundle id, or the
> component dependencies.
> As an example, let's assume we are using the AMDATU mutli-tenancy framework.
> With AMDATU MT, many internal AMDATU components are instantiated behind the
> scene for a given tenant bundle.
> In the following example, we have three tenant bundles, and if we type "dm",
> then we are getting a long list of components, including:
> - application tenant components: pierre.multitenant.*
> - some internal amdatu mt components (org.amdatu.multitenant.*):
> g! dm
