[FELIX-5802] Service Component created via xml defines scope='singleton' and service specifies property with scope='bundle'

• Type: Bug

Description

Component with scope='singleton' created via xml or annotation has the service registered with a property of service.scope='bundle'

Project reproducing the issue is available here: https://github.com/mattrpav/felix-5802 

Steps to reproduce:

1. Define a serviceComponent via xml (or osgi ds annotation)
2. Deploy bundle
3. run scr:info (observe Service Scope: singleton)
4. run service:list (observe service.scope = bundle)

Investigation:

• Service registers with property of 'service.scope=bundle' here: https://github.com/apache/felix/blob/trunk/framework/src/main/java/org/apache/felix/framework/ServiceRegistrationImpl.java#L327
• Debugging in felix.scr confirms that the xml is being parsed correctly and the returned component metadata shows the 'scope' = 'singleton' correctly o.a.felix.scr.impl.xml.XmlHandler#L362
• Debugging confirms that felix.scr is detecting DS13 namespace

 scr:info output:

karaf@root()> scr:info TestModule
*** Bundle: com.foo.test-module (124)
Component Description:
Name: BundleModule
Implementation Class: com.foo.TestModule
Default State: enabled
Activation: immediate
Configuration Policy: optional
Activate Method: activate
Deactivate Method: deactivate
Modified Method: -
Configuration Pid: [TestModule]
Services: 
com.foo.api.Module
Service Scope: singleton
Component Description Properties:
Component Configuration:
ComponentId: 4
State: active 
Component Configuration Properties:
component.id = 4
component.name = TestModule

service:list output

karaf@root()> service:list
[com.foo.api.Module]
------------------------
component.id = 4
component.name = TestModule
service.bundleid = 124
service.id = 141 
service.scope = bundle

Company :: Foo :: TestModule (124)

OSGI-INF/serviceComponent.xml

<?xml version="1.0" encoding="utf-8"?>
<scr:component xmlns:scr="http://www.osgi.org/xmlns/scr/v1.3.0"      name="TestModule" immediate="true">
    <service scope="singleton">
        <provide interface="com.foo.api.Module" />
    </service>
    <implementation class="com.foo.TestModule" />
</scr:component>

 

Note: When the same impl class is reconfigured to register as a service via BundleActivator, the service has a service.scope = 'singleton'
