[jira] Created: (TUSCANY-2766) Warning message conflicts with
conformance item ASM60008
Warning message conflicts with conformance item ASM60008
---------------------------------------------------------
Key: TUSCANY-2766
URL: https://issues.apache.org/jira/browse/TUSCANY-2766
Project: Tuscany
Issue Type: Bug
Components: Java SCA Assembly Model
Affects Versions: Java-SCA-1.3
Reporter: Shu Chao Wan
I'm testing conformance item ASM60008, and found something strange.
In ASM60008, it says that "The interfaces of the component references promoted by a composite reference MUST be the same, or if the composite reference itself declares an interface then all the component reference interfaces must be compatible with the composite reference interface. Compatible means that the component reference interface is the same or is a strict subset of the composite reference interface."
In order to verify this statement, I wrote a composite file like that
<composite>...
<service name="AService" promote="AComponent"/>
<component name="AComponent">
<implementation.java
class="org.apache.tuscany.sca.vtest.assembly.composite.impl.AServiceImpl" />
<reference name="b"/>
<reference name="c">
<interface.java interface="org.apache.tuscany.sca.vtest.assembly.composite.CService" />
</reference>
</component>
<reference name="c" promote="AComponent/c">
<interface.java interface="org.apache.tuscany.sca.vtest.assembly.composite.CSuperService" />
</reference>
<reference name="b" promote="AComponent/b"/>
<service>
</composite>
Here, the interface CSuperService is super set of interface CService, that is to say, interface CSuperServicecontains more methods than interface CService does.
But when I load this composite file, I got warning message:
Jan 12, 2009 11:27:27 AM org.apache.tuscany.sca.assembly.builder.impl.CompositePromotionBuilderImpl
WARNING: Interface of composite reference AComponent/c must be compatible with the interface declared by promoted component reference.
Jan 12, 2009 11:27:27 AM org.apache.tuscany.sca.assembly.builder.impl.ComponentReferenceWireBuilderImpl
WARNING: Incompatible interfaces on component reference and target: Composite = {http://assembly-tests}Assembly-sub-reference-interface-outer-Composite Reference = c Service = CComponent
It seems that this warning message conflicts with this conformance item, which causes that service can not be invoked correctly in the following test.

[jira] Resolved: (TUSCANY-2766) Warning message conflicts with
conformance item ASM60008

Dan Becker resolved TUSCANY-2766.
---------------------------------
Resolution: Invalid
Hello Shu Chao Wan,
You've cited the correct conformance item and provided a very good test case. However, I think there are multiple interpretations of the meaning of "Compatible means that the component reference interface is the same or is a strict subset of the composite reference interface."
One meaning of compatible is that all methods in the component reference interface (in your example CService) are the same or a subset of the composite reference interface (in your example CSuperService). Your example shows this and the 2 methods of CService interface are contained as a subset of the 3 methods of CSuperService.
Another meaning of compatible is that the interface of the component reference interface implements a subset of the interfaces that the composite reference interface implements. In other words, is component interface assignable from composite interface? Do they have a super/derived interface defined in the object hierarchy? The Tuscany implementation uses this later meaning.
Since your example has no assignable relationship between the two interfaces, they are not compatible. (Otherwise SCA implementation would have to introspect interface methods and compare sets which might take a while. AssignableFrom testing is quicker.) You may retry your example by providing object oriented hierarchy of CSuperService and CService to test this.
(If you do not like this explanation, you may reopen, and we can raise the issue on the developer list.)
