Subject [jira] [Commented] (KARAF-4980) OSGi framework capabilities: add all services
Date Tue, 07 Feb 2017 09:44:41 GMT

    [ https://issues.apache.org/jira/browse/KARAF-4980?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15855652#comment-15855652
] 

Markus Rathgeb commented on KARAF-4980:
---------------------------------------

I already asked some time on the mailing list, because AFAIK "effective:=active" is only used
for "Require-Capability"
See: http://karaf.922171.n3.nabble.com/What-does-effective-active-mean-tp4047770p4047787.html

Also this comment I found on some vogella site seems to be informative that it is only necessary
for "Require-Capability" and not for "Provide-Capability"
"You should notice the effective:=active directive here. It is necessary so the OSGi Framework
will resolve the bundle without checking if another bundle provides that capability. Without
that directive or setting effective:=resolve the resolution of the bundle would be prevented."

I updated the PR:
* I removed "effective:=active"
* I removed all services that are already provided (in the bundle:headers 0 list)
* I added all capabilities where properties are missing
* I added the missing capabilities

> The services provided by the Felix and the Equinox framework differs and should be provided
by the system capabilities.

are provided by Equinox.

you agree):
