Subject [jira] Commented: (FELIX-102) Implement singleton bundle support
Date Tue, 05 Aug 2008 19:38:44 GMT

    [ https://issues.apache.org/jira/browse/FELIX-102?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12620014#action_12620014

Richard S. Hall commented on FELIX-102:
---------------------------------------

After looking into this some more, I think what we need to do is make two modifications:

1. Modify our methods that find candidates to pre-filter any singleton candidates that have
a singleton with the same symbolic name already resolved in the installed bundle list.
2. Modify findConsistentClassSpace() to check the current set of selected candidates to see
if there are any duplicate singletons selected to be resolved, if so, increment the candidate
configuration.

Step 1 is not strictly necessary, but it will avoid unnecessary inconsistencies for candidates
that can never be chosen.
