Description

 

Description

1. Felix tries to resolve other bundles, even when the bundle has the capability for the requirement by its own

2. Felix resolves bundles, which are only required by bundles that aren't in the resolve result

 

 Example: https://github.com/stbischof/ds.resolve

 

try to resolve bundle req

• bundle req has the requirement namespace="ns",name="name"

so we look for the same capability namespace="ns",name="name"

• bundle cap has the capability namespace="ns",name="name"
• but bundle cap has also a Requirement osgi.service;filter:="(objectClass=java.lang.Readable)";effective:=active;cardinality:=multiple.
• this could be providet by itsselve osgi.service;objectClass:List<String>="java.lang.Readable" (target property of @Reference is not processed)

Issues:

• it resolves bundle capfora which provides a capability that is required by bundle a -> provides also the capability that is required from bundle cap ( osgi.service;objectClass:List<String>="java.lang.Readable").
• But in this case bundle a is not in the resolveresult
• bundle b is also resolved. (not needet, cap has the needet capability by its own)

 

Reproduce:

bndtools/eclipse

push the resolve button at ds.resolve/resolveActive.bndrun

commands

 

git clone https://github.com/stbischof/ds.resolve.git
cd ds.resolve
java -jar biz.aQute.bnd-4.1.0.jar clean
java -jar biz.aQute.bnd-4.1.0.jar _par
java -jar biz.aQute.bnd-4.1.0.jar resolve resolve --write ds.resolve/resolveActive.bndrun
git diff

 

 

results:

+-runbundles: \ + ds.resolve.b;version=snapshot,\ + ds.resolve.cap;version=snapshot,\ + ds.resolve.capfora;version=snapshot,\ + ds.resolve.req;version=snapshot,\ + org.apache.felix.scr;version='[2.1.0,2.1.1)'
