Subject [jira] [Created] (KARAF-5664) Service Component created via xml defines scope=''singleton' and service is created with scope='bundle'
Date Fri, 09 Mar 2018 18:53:00 GMT
Matt Pavlovich created KARAF-5664:
-------------------------------------

             Summary: Service Component created via xml defines scope=''singleton' and service
is created with scope='bundle'
                 Key: KARAF-5664
                 URL: https://issues.apache.org/jira/browse/KARAF-5664
             Project: Karaf
          Issue Type: Bug
          Components: karaf-scr
    Affects Versions: 4.1.5
            Reporter: Matt Pavlovich


 

Steps to reproduce:
 # Define a serviceComponent via xml
 # Deploy bundle
 # run scr:info (observe Service Scope: singleton)
 # run service:list (observe service.scope = bundle)

Investigation:
 * 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|https://github.com/apache/felix/blob/trunk/scr/src/main/java/org/apache/felix/scr/impl/xml/XmlHandler.java#L362]

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

Provided by :
Company :: Foo :: TestModule (124){noformat}
OSGI-INF/serviceComponent.xml
{noformat}
<?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>{noformat}
 

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