Subject [jira] [Commented] (CELIX-443) Add bundle tracking API to bundle context
Date Sun, 06 May 2018 19:21:00 GMT

    [ https://issues.apache.org/jira/browse/CELIX-443?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16465262#comment-16465262

Pepijn Noltes commented on CELIX-443:

An initial implementation is added, but currently locking is not working correctly. 
As far as I can see the framework.c needs an update bundle locking, I do not understand the
current implementation and for me it seems to complex.

I think it is possible to use the same approach as in the service tracker: 
- lock the bundle list with a rw lock and
- per bundle entry maintain a (mutex protected) use count.
- The use count should also have a condition, so that it is possible to 
- a) remove a bundle from the list and then
- b) wait until the use count == 0
