New prefs. Don't think about the symbolic name when dealing with Prefs. Prefs predates symbolic name. All Prefs can know is bundle id and bundle location. The Prefs spec is mute on which is the primary key for the prefs data. However the ref impl uses bundle id. I have opened an issue for CPEG to decide which it should be and will we then update the spec text and perhaps issue an erratum. I expect bundle id will be the choice since that is the behavior of the ref impl.
So in your scenario A and B and C all have different bundle ids. Therefore none of them can see any of the others preferences.

Ok, so what should happen in the following scenario: Bundles A and B are installed at the same time. They have the same symbolic-name but different versions. They both use prefs, so they have their own preferences. The Preferences Impl bundle is shutdown... ... sometime later the Preferences Impl bundle starts up again. Bundles A and B are no longer installed. However there is a new Bundle C that has the same symbolic-name as A & B. When Bundle C asks for it's prefs, what should it get? A's prefs, B's prefs, or new prefs?

Should the bundles share the same > preferences or should they each have their own? Technically, these are 2 distinct bundles. Each has a distinct bundle id and bundle location. Therefore, Prefs must treat each as a seperate bundle and give them each their own preferences. If the there was only one bundles installed and it was updated to a new bundle version, then the updated bundle would then use the prefs from the original bundle. This is because they are the "same" bundle to Prefs: they have the same bundle id and bundle location. > > This question came up in Eclipse bug https://bugs.eclipse. > org/bugs/show_bug.cgi?id=124176#c5 > > Regards, > Roy Paterson > > ----------------------------------------- > Roy Paterson > IBM Pervasive Computing > Austin, TX > Phone: (512) 838-8898_______________________________________________ > osgi-dev mailing list > osgi-dev@bundles.osgi.org > http://bundles.osgi.org/mailman/listinfo/osgi-dev BJ Hargrave Senior Technical Staff Member, IBM OSGi Fellow and CTO of the OSGi Alliance [EMAIL PROTECTED] Office: +1 407 849 9117 Mobile: +1 386 848 3788 _______________________________________________ osgi-dev mailing list osgi-dev@bundles.osgi.org http://bundles.osgi.org/mailman/listinfo/osgi-dev _______________________________________________ osgi-dev mailing list osgi-dev@bundles.osgi.org http://bundles.osgi.org/mailman/listinfo/osgi-dev _______________________________________________ osgi-dev mailing list osgi-dev@bundles.osgi.org http://bundles.osgi.org/mailman/listinfo/osgi-dev
